Indian Navy SSB Interview Procedure
Many defense aspirants dream of being an Indian Navy officer or army officer or Air Force officer. There are several aspects that a candidate needs to focus while attending SSB Interview as one has to cross this barrier of selection to get recruited in defense services. So as to be selected in Indian defense services overall development of personality, knowledge and body is required. Candidate need to brush up his knowledge and bring him officer like qualities, in short one need to adapt an environment of defense services, discipline and attitude to get in SSB Interview. First step is to apply through exams like National defense academy (NDA) or combined defense service examination (CDSE) or Air Force Common Admission Test (AFCAT).
Second method is to apply various army, navy or air force courses and get admission through academic records after graduation through which a candidate needs to go for SSB Interview. SSB Interview is conducted as test in which there are different stages that candidate have to crack. It's a complete procedure of 5 days and they are mentioned as below:
The very first day of selection is the stage-1, where the candidate faces picture perception and description test and intelligence test for the analyzing of aptitude level of candidate. The tests that are carried out are as follows:
- Picture Perception and description test
- Intelligence Test
- Analyzing the Picture
- Candidates need to focus on the vital points like facts, characters, moods in the image, Gender and their age. Keen observation is required when pictures are shown to aspirants for writing a brief story.
The second day of selection is based upon the selections that had happened before in the previous round of selection i.e. stage-1. Those candidates need to focus on the next stages that they will face for test like:
- Thematic Apperception Test
- Word Association Test
- Situation Reaction Test
- Self-Description Test
These tests are conducted to know that how much attention does candidate pay while observing and their sense of judging things and situations.
This is the stage from where the complete procedure of performing in a group is carried on that is known as GTO Round-1. In this stage candidates need to face several tasks like:
- Group Discussion
- Group Planning Exercise
- Progressive Group task.
- Group Obstacle Race
- Half Group Task
This is the stage-4 that is carried out after candidate clears their third round of interview which was carried on day-3 and in this stage the tasks carried are:
- Individual Obstacles
- Command tasks
- Final Group Tasks
This round is last and final in which the candidates complete all the tough modes of task and last round in which conference is held where interview officer panel interview candidate i.e. personal interview is carried out on day-5 just normal round of questioning.
Once these all days are cleared candidate got hired as per his scoring in per round from day-1 to day-5.

New Smyrna Beach
New Smyrna Beach occupies a notable place in history as the site of the largest single attempt at colonial settlement in what is now the United States. Dr. Andrew Turnbull, a Scottish physician and entrepreneur, obtained a grant of land from the British Crown. In 1768 he established a colony of 1,225 immigrants on the coastal plantations at New Smyrna, with a view toward the commercial production of such crops as corn, indigo, rice, hemp, and cotton. The land that the Turnbull colonists settled is located along the west bank of the Indian River, opposite one of coastal east Florida's relatively few inlets.
For some 10,000 years before the arrival of the Europeans, Native Americans inhabited the area, initially on a nomadic basis and later in more sedentary camps and villages. Until the early twentieth century, the coastline was strewn with mounds of ancient refuse that testified to the presence of the Indians. Most of the mounds were destroyed, the shell used for roads and building construction material. However, much evidence of prehistoric habitation remains hidden under ground and water within the corporate limits of New Smyrna Beach and beyond. Read Complete History


MapleSim Connector for JMAG-RT
Share this on social media:
Maplesoft has launched a product that allows users to combine the powerful finite element analysis abilities of JMAG with the advanced physical modelling approach of MapleSim. The MapleSim Connector for JMAG-RT allows engineers to produce high-fidelity system models that seamlessly incorporate components from each system.
MapleSim is an advanced physical modelling and simulation tool that applies modern techniques to dramatically reduce model development and analysis time while producing fast, high-fidelity simulations.
JMAG is a powerful finite element analysis (FEA) tool that allows engineers to develop, analyse, and fine-tune electric motors and generators, taking into account such diverse factors as thermal, structural, and vibration issues. With the new connector, engineers can incorporate their JMAG motors and generator models into a MapleSim system-level model.
This ability allows users to study interactions between their motors and generators with other components of the final product. For example, in a hybrid-electric vehicle, the behaviour of the battery, the internal combustion engine, the tires, and other elements of the car can have a significant impact on the performance of the electric motor. By incorporating all these diverse elements into a single system-level model, the engineer can better understand and optimise the behaviour of the entire design, avoiding unpleasant surprises at the prototype stage.
'Different tools are suited for different tasks, so it is vital that today's engineers have the ability to easily move from tool to tool as they work on their project, without incurring tremendous overhead costs in the process,' said Laurent Bernardin, executive vice president and chief scientist at Maplesoft.


Notes to "Note to Self"
program notes by Mia Ferm
(program notes written for Note to Self: The Psychosexual films of Nazli Dinçel @ ERC 2/23/2016)
Lovemaking is not fluid. We start, stop, adjust, try too hard or not enough, let go, and enjoy. A certain mechanics is involved that can include both successes and failures. So too it is with moviemaking: roll, cut, and adjust for the right angle or shot. Rarely though is such disruption displayed for us as viewers, when sex is neatly packaged up in everything from Rom-Coms to Pornos. Even violence can seem fluid. Disruption, however, is a major theme in the film work of Nazli Dinçel, who takes to task representations of female sexuality through a highly personal artist's cinema, with often only a crew of one, both behind and in front of the camera, and imbedded into the actual material surface of her medium of choice, 16mm film.
"She locks the bathroom door." —Solitary Acts #4
For Solitary Acts #4, the filmmaker positioned the camera with remote shutter release and positioned her body to record as both camera operator and actor the so-called solitary act of masturbation. So-called because it is ultimately part of a public experience. About two-and-a-half minutes in and filling the frame with a warmly-lit vagina, hand sliding in and out, there is a question of what exactly is being recorded. The self, the body, pleasure? With the penis it's just so much easier to recognize both arousal and the moment of orgasm. It's obvious, visible, and potentially valuable. Writing about pornography in her book Hard Core: Power, Pleasure, and the "Frenzy of the Visible" Linda Williams notes, there is a "reliance on visible penile ejaculations (money shots) as proof of pleasure" (p. 8). Quelle photogénie! But these physiological responses aren't quite as evident (or represented) when it comes to female genitalia. One must wonder how pleasure presents itself (and really in terms of images, presents itself for whom?).
Defined as relating to mental, emotional, and behavioral aspects of sexual development (Miriam-Webster Dictionary), psychosexual is a Freudian term, with psychosexual energy as the driving force behind one's behavior as an adult, arrived at via five infamous childhood stages (i.e. oral, anal, etc.). While not an actual correlate, Dinçel's Solitary Acts #4 and #5 chronologically reveal to the viewer certain moments in the sexual awakening of a young girl into her teen years. Of course, it isn't the explicit imagery that is telling us, but rather those things that disrupt it. From what Freud taught, a disrupted stage leads to certain fixations later in life.
"She imagines kissing, sucking, kissing…" —Solitary Acts #5
Confession seems too loaded a term, but it's something like that, scratched onto the surface, frame-by-frame, of the film acetate, sometimes creating multiple columns within a single frame as in Her Silent Seaming or Solitary Acts #5; and to add tedium to envisioning such a tedious production task, let us not forget that just one second at a regular frame rate is composed of 24 frames. Even without fully understanding this aspect of production, the vibrating or typewritten words almost peeling off the surface demonstrate an intensity in her work as text/body and as therapeutic method. As Dinçel herself writes, "[o]ver-working the subject matter is a form of healing. The content is exhausted in the making of the films." Light-leaks and other imperfections of hand-processing also intrude along with the cuts from the exacto knife, the punches from a sewing machine and typewriter, or the blows from a hammer that the film acetate receives. Manipulation of the film's surface is more than a metaphor for the malleability of the body.
"He says it's ok, I don't like coming…" —Her Silent Seaming
Direct cuts to the optical track are also part of Dinçel's production, disrupting the physical surface to effect the aural and visual experience. Recounting moments of intimacy in Her Silent Seaming, again via scratched text and in a mainly he said/he said address, over colorful and imperfect images of male genitalia and finally a symbolically eviscerated pomegranate, there is a pulsing pop that the filmmaker instructs should be played loud. But what we hear is not exactly when we see. Between the lens of the projector and the sound head there are 26 frames, meaning that what we hear is a past image. It's impossible to catch up.
In her artist's manifesto, Dinçel qualifies her interest in pornographic imagery, clarifying that her use of this imagery "is not primarily meant to arouse the viewer." In addition to the complexity and intensity of the subject matter (far too much to unpack in these program notes), one shouldn't ignore the beauty and humor of her work. The use of pop music, for example in Solitary Acts #4 with slow-mo Britney teasing "oops, I did it again," is half making-fun at the filmmaker's own relatable experiences of so-called bad sex. Making an appearance in all three of the Solitary Acts films, transforming as it is strung along, is that dang dangling carrot wrapped up in Freudian fixations to arrive as an unintentionally ironic metaphor. And at the center of the program "Note to Self" is the found film Sharing Orgasm: Communicating Your Sexual Response (1977) that is so earnest both in its original screenplay and in Dinçel's placement of it as an attempt to mend past failures that its humor becomes highly palpable.
In terms of beauty, however, a stand out film might be Leafless (2011), which on its sensual surface seems like an update of Willard Maas's Geography of the Body (1943), but now warmly-colored and somehow both fantastic and familiar, with cuts to real landscapes between the peaks and valleys of a lover's body. Dinçel admits to never having seen the Maas film and while the body as landscape is hardly a novel concept, it is where her film is coming from that feels different.
Meant as a poem of textures, Leafless is a hand-processed film made by a young woman whose multi-located childhood between Turkey, the US, and Switzerland, appears in much of her work under the theme of dislocation. Although visually abstracting the body, the film has the sense of locating oneself by becoming familiar with a lover's body as/via landscape. The sensual is found equally in the skin of a hand, the trunk of a tree, a penis, and shimmering reflections in the water. Is lovemaking fluid here? We can't really know, but like Nazli Dinçel's other films it feels honest, real, and tentative, accepting of its disruptions.

Improved Limits on Spin-Dependent WIMP-Proton Interactions from a Two Liter CF3I Bubble Chamber
Data from the operation of a bubble chamber filled with 3.5 kg of CF3I in a shallow underground site are reported. An analysis of ultrasound signals accompanying bubble nucleations confirms that alpha decays generate a significantly louder acoustic emission than single nuclear recoils, leading to an efficient background discrimination. Three dark matter candidate events were observed during an effective exposure of 28.1 kg-day, consistent with a neutron background. This observation provides the strongest direct detection constraint to date on WIMP-proton spin-dependent scattering for WIMP masses >20 GeV/c^2.

Underlying theory of Concept Maps: Concept maps have strong academic roots. Here are four important scholarly papers by Joseph D. Novak and Alberto J. Cañas about their construction and theory.
An overview of concept mapping: Eric Plotnick's 1997 article from the ERIC Clearinghouse on Information and Technology Syracuse NY.
Concept maps and web research: As I research – I build a map. As I map – I realise new areas that need research. So for me, web research and concept maps are a natural fit. These papers variously by Arguedas, Cañas, Carnot, Carvalho, Dunn, Eskridge, Gram, Leake, Maguitman, Muldoon and Reichherzer have helped me to understand why, and see other possibilities.
Semantic networks: This article by John F. Sowa, originally written for the Encyclopedia of Artificial Intelligence, describes the broad term "Semantic network".
Visual representation of knowledge: Sigmar-Olaf Tergan is an academic leader in the field, and here are links to some of his articles on the visual representation of knowledge.
Assessment by concept map: Do concept maps offer one way of judging students' knowledge structure? This discusses the nature of knowledge, and the difficulty in measuring achievement in the three types of domain knowledge.
Knowledge mapping for communities: Simon Buckingham Shum and Alexandra Okada make a case in this interesting slideshow for a move away from text towards knowledge or mind mapping presentation in a knowledge community. Their objective is to change cognition, no less.

This study was conducted to analyze the background factors and achievements of the ASEM process over the past 25 years since its establishment and to draw policy implications for Korea.
After the Introduction, Chapter 2 reviewed, in a detailed manner, the background factors of and the roles assigned to the ASEM process. Especially, ASEM was identified as an inter-regional cooperation mechanism between the two continents – Asia and Europe – that was established in order to fill the 'missing link'. The intention of European countries to intensify cooperative relationship with Asian countries that had been increasingly recognized as 'the potential center of global economic growth' was a mian background factor that led to the establishment of ASEM. Also crucial was the desire of Asian countries to diversify their diplomatic relationship and to cultivate the biggest internal market provided by the European integration process. In addition to its traditional role to foster and enhance the cooperative relationship between Asia and Europe, the ASEM process also contributed to strengthening the intra-regional cooperation within Asia by providing them with motivations to establish the ASEAN+3 and the East Asia Summit (EAS), which can be regarded as a very positive by-product.
Chapter 3 was fully devoted to the evaluation of ASEM cooperation. First of all, the study looked into the agenda items of twelve summit meetings held until October 2021 in order to identify the main direction of cooperation in the ASEM process. Also, the study thoroughly investigated the cooperation agenda discussed and the frequncy of ministerial meetings, and found out that the ASEM process has been well-balnaced between political and economic policy areas. As a result of qualitative evaluation of the ASEM process, the study brought into discussion the following five main weaknesses of the ASEM process, especially compared to other internaitonal cooperation bodies, such as the APEC process. (i) unclear long-term vision; (ii) very low degree of institutionalization with no physical secretariat; (iii) too much comprehensive cooperation agenda leading to a low degree of concentration and focus; (iv) non-binding characteristics leading to no meaningful commitment of members; and (v) low visibility of the whole process.
Chapter 4 examined the trends and characteristics of the ASEM enlargement through indicator analysis. The European Commission's Joint Research Center created a sustainable connectivity indicator and analyzed the degree of connectivity between Europe and Asia by collecting basic data from ASEM member countries. As a result, it was confirmed that significant achievements were made between the two regions in terms of trade, investment, movement of people, institutional and political connectivity, and joint research between the Asian and European regions. However, the European Commission's Joint Research Center's Sustainability Connectivity Indicator is not only Europe-centered, but the data is collected at a specific point in time. In order to supplement weakness of the Sustainability Connectivity Indicator, we created a new governance indicator that shows the degree of connectivity between the three pillars of ASEM. New indicator clearly illustrates trends and characteristics within and between the two regions in the process of ASEM enlargement. Furthermore we examined changes in Korea's status in the process of ASEM enlargement using the governance indicator. According to analysis results Korea showed a high growth rate far exceeding the average of ASEM member countries in all areas including the public sector, market, and civil society. And compared to the early days of ASEM, Korea's relative standing of nowadays has risen significantly. In particular, the degree of improvement in areas such as pulic administration, market environment and welfare was remarkable.
Chapter 5 presents Korea's strategies for the upcoming 25 years of ASEM based on Korea's achievements within ASEM. The future strategies will be was proposed focusing on areas where Korea can demonstrate intellectual leadership within ASEM. Indicator studies have shown that within ASEM, Korea has set a best practice in the areas of market opening, social security and deregulation. In addition, the Asia-Europe education cooperation program is also a major area in which Korea can demonstrate its intellectual leadership in the future. Future strategies proposed by Korea, such as market opening, social security, deregulation and education, are expected to make a significant contribution to the process of overcoming the challenges ASEM member countries are facing in the post covid-19 era.

The Ohio Air Quality Development Authority (OAQDA) administers the Qualified Energy Conservation Bonds (QECB) program in Ohio. QECBs have been used by local governments and public universities to finance the installation of energy conserving equipment in publicly owned buildings. Under a QECB financing package, OAQDA authorizes Air Quality Development Bonds for issuance as a Series A federally tax-exempt bond and a Series B Qualified Energy Conservation Bond (QECB) federal tax-credit bond. Combining funding from the two separate sources results in a lower, "blended" interest rate for the participating entity.
Qualified conservation purposes include:
Capital expenditures that will reduce energy consumption in publicly owned buildings by at least 20%, fund green community programs, or support rural development involving the production of electricity from renewable sources;
Research expenditures that support the development of cellulosic ethanol or other non-fossil fuels, technologies for the capture and sequestration of carbon dioxide, increasing the efficiency of existing technologies for producing non-fossil fuels, automobile battery technologies to reduce fossil fuel consumption in transportation or technologies to reduce energy use in buildings;
Mass commuting facilities;
Demonstration projects that promote commercialization of green building technology, conversion of agricultural waste, advanced battery manufacturing technologies, technologies to reduce peak electricity consumption or technologies for the capture and sequestration of carbon dioxide emitted from fossil fuels that produce electricity; and
Public education campaigns to promote energy efficiency.

There is a close correlation between culture and economy, and economic development of any region is inseparable from cultural factors. Qi-Lu culture, as one of the traditional Chinese cultures, exerts a profound impact on economic development of Shandong. This paper analyzes the similarities and differences between Qi culture and Lu culture, and takes economic development of Jining and Zibo as examples to investigate the characteristics of regional economic development in Shandong Province under the impact of the two cultures. Regional economic development is inseparable from driving force of culture. Traditional culture not only needs to be promoted, but moreover, reformed and innovated. Only in this way can we promote the construction of Shangdong as a strong economic and cultural powerhouse. Culture means a tradition. It is under combined action of factors like a region's unique geographical environment, natural conditions, customs, humanities, history, politics that the region's unique culture is formed[1]. Economy is formed on certain cultural basis. The development of regional economy is inseparable from the driving force of regional culture. In turn, the economy acts on the inheritance and development of culture[2]. The integrated development of culture and economy can not only provide a source of power for economic development, but also carry forward the promotion and prosperity of culture.

Can Video Games Help Kids Eat Healthy?
The study, published in the American Journal of Preventive Medicine, compared the effects of two epic video adventure games to two knowledge-based video games on children's behavior. All of the games were designed to motivate children to make healthy lifestyle changes including increasing fruit and vegetable intakes, water consumption, and physical activity.
Games that grab them are more effective
The 133 children in the study were 10 to 12 years old and had BMI (body-mass indices) that indicate they were overweight or at risk to be overweight (between the 50th and 95th percentiles for age). They were assigned to either the adventure games group or the knowledge games group. The adventure games ("Escape from Diab," referred to as Diab, and "Nanoswarm: Invasion from Inner Space," referred to as Nano) were both epics consisting of nine sequential sessions, each building on gains from the previous session. Behavior-changing motivators were incorporated into the stories at the centers of the games. The knowledge games involved a similar number of game-playing sessions, providing information about nutrition and lifestyle and interactive quizzes.
At the end of the trial, children in the adventure games group had made more substantial changes in fruit and vegetable intakes and physical activity than the children in the knowledge games group. The biggest difference between the groups was in fruit and vegetable consumption. "The games motivated players to substantially improve diet behaviors," the study's authors said. "[However,] fruit and vegetable intake and water consumption and physical activity were still below the minimum recommendations, indicating that more work is needed."
The Popeye effect
It should come as no surprise that engaging stories affect children's behaviors. The popularity of Popeye, the spinach-eating cartoon hero who appeared regularly in comics in the 1930s, was credited with a 33% increase in spinach consumption in the US during that decade. Even as recently as 2010, researchers have found that children eat more spinach after viewing Popeye cartoons.
If you can't beat 'em, join 'em
Parenting advisors invariably suggest limiting screen time for many good reasons, including getting kids to be more active. Despite this sound advice, the Kaiser Family Foundation recently reported that children between 8 and 18 years old spend an average of 7.5 hours per day using computers, television, and other electronic devices.
Introducing your kids to engaging video games that effectively lead to healthy lifestyle changes is one way to intervene in the trend. To learn more about new health-promoting video games that are being developed, visit _URL_.

. Analysis of Synthetic Data
To analyze the accuracy of the reconstructed HARDI models in the synthetic data sets, we report the detected angular error. We use a simple scheme for determining the angular error, that is, we find the local maxima of the reconstructed profiles on a mesh generated by tessellating icosahedron of certain order and then report the angular difference between these maxima and the simulated (true) fiber directions. To reduce the error that the discrete mesh imposes, in our analysis we use the 7th order of tessellation of the icosahedron, that imposes 1° spacing between tessellation points, thus, a maximum distance between any point and the nearest tessellation point of 0.5°. Depending on the orientation of the fibers in the space of the gradients, different errors might appear for the same simulated angle. For example, if we simulate an angle of 60° by two crossing fibers and then rotate the fibers in 3D space, one would assume that always the same angle of crossing is detected. However, in Söderman's model, different angular errors are calculated for different orientations of the fibers. In general, these errors cause less than 5° angular error, and therefore while choosing our optimal parameters for certain angular configuration, we take these errors into account. For example, for an angle of 60°, the -value of 3000?s/mm2 might give an angular error of 4° and the -value of 4000?s/mm2 an angular error of 2.5°. However, due to the errors imposed by the tessellation of the mesh and the orientation of the fibers as well as our choice of tolerance for 5°, we report the b-value of 3000?s/mm2 as preferable, since both -values are within our range of tolerance, and we always report the smallest -value as optimal.
2.5. Analysis of Human Data
2.5.1. Criteria for In Vivo Data Analysis
For qualitative analysis of the real data, we select the centrum semiovale (CS) (see Figure 2) where crossings are to be expected. This is a challenging region for DW-MRI analysis techniques, since fibers of the corpus callosum (CC), corona radiata (CR), and superior longitudinal fasciculus (SLF) form a three-fold crossing. A region-of-interest (ROI) was defined on a coronal slice. Red rectangle indicates the position of the slices in the acquisition.
The qualitative criteria for comparison are the sharpness of the profiles in CC and lower parts of the CR, the presence of two ODF maxima for the CC and CR and the spread of the their crossing in the centrum semiovale, and the presence of the superior longitudinal fasciculus in the upper corners of the region. Furthermore, the presence of spurious peaks is an indication of poor SNR and unreliably detected crossings.
2.5.2. SNR in In Vivo Data
We calculate the SNR in the images via the "difference method" as described by Reeder, et al.. For a set of two unweighted volumes, the SNR is computed via the difference method as where and are two unweighted images and and are the mean and the standard deviation respectively. The SNRs, computed in an ROI of 60 voxels in the middle of the corpus callosum, is 23.58, 20.75, 19.29, and 18.61 at -values of 1000, 1500, 2000, and 3000?s/mm2, respectively. The final reported SNR is calculated as the median of six SNRs, each computed from two unweighted images closest in time. Since unweighted volumes were interspersed between 12 diffusion weighted volumes, the SNRs are probably slightly under-estimated due to bulk motion and drift over the measurement time. Note that, due to the characteristics of the phased-array RF coil, the SNR in the CC in the middle of the head is a lower bound for the SNR in the rest of the scanned volume. SNR is expected to increase (quadratically) towards the periphery.
2.5.3. Scanning Time
To give an indication for the time requirements for the individual acquisition schemes, we estimate the total scanning time needed to obtain a full brain acquisition at the given parameters. Assuming at least 60 axial 2.5?mm slices would be needed for whole brain coverage and the shortest achievable TR would be used, whole brain measurement times are given in Table 3.
In this section we will discuss the quantitative results from our synthetic data and give qualitative implications for the real data scanned under the same parameters.
3.1. Synthetic Data Analysis
To get an indication on the optimal parameters for each simulated angle, we run a series of tests, where we determine the minimal angular error that can be obtained with the minimal combination of -value and -order, under different gradient sampling schemes. The results are presented in Table 4.
We observe similar trends for both of the reconstruction techniques. Both Q-ball and DOT-ODF can accurately represent crossings of 90° for -values as low as 1000?s/mm2 and order of SH regardless of the choice for the gradient sampling scheme. The scenario changes for the angle of 60°, where the best choice for -value recommends 3000?s/mm2 and higher order of SH of. Trying to resolve smaller angles of crossings, with these analytical decomposition methods results in higher choices for -values and SH order even in noiseless cases. The SNRs in clinical scanners at high -values such as 4000?s/mm2 drop and therefore these -values are not recommended. The noise corrupts the reconstructed profiles, and modeling with high orders of SH will result in capturing the noise, which is dominant in these cases. Therefore, from the noise tables (see Supplementary Material available online at _URL_ we already get the indication that the lowest angle which can be captured within reasonably imposed angular error would be around 60°. To reduce the parameter space, we therefore select this interesting angle and SH order of (as Table 4 indicates for this angle) and look at some interesting influences of the -values and number of gradients, under different SNRs. Another motivation for this choice of reconstruction angle is the region that we select for illustrating the in vivo results. The centrum semiovale contains a large amount of voxels where the crossing angles are approximately between 60° and 90°. To investigate the effect of the gradient sampling schemes, we performed tests where for -values of 2000?s/mm2, we vary the number of gradients under different levels of added Rician noise. In Figure 3, we report the calculated angular error and the standard deviation of 100 noise realizations for simulations of 60° angle of crossing. We observe that for SNR of about 20 (similar to our case) of the recovered angle suffers from an angular error of less than 10°. For higher SNRs (20–40), we observe that around a number of 70 gradients the graph stabilizes and we do not gain much accuracy by having denser gradient sampling schemes. The results are similar to the ones from the DOT-ODF and for completeness are reported in Figures 8, 9 and 10.
In a similar fashion, we investigate the effect of the -value, on the accuracy of the reconstruction techniques under different SNRs. From the previous discussion, we concluded that the number of 70 gradient direction is sufficient for good detection of a 60° crossing fiber configuration, and therefore in this analysis we fix the number of gradients to 72 (Figure 4). For data with SNR 10, there is a clear tendency for an optimum -value of around 2000?s/mm2 as seen in the decrease in the angular error. Higher -values, produce worse results with high standard deviations. However, if the SNRs are higher, the angular error and the standard deviation decay and stabilize around -values between 2000?s/mm2 and 3000?s/mm2. Again, the results coincide with the ones from the analysis of analytical DOT-ODF, and for completeness are reported in Figures 8, 9 and 10.
The previous analysis emphasizes the importance of the SNRs for reliability in the reconstruction of analytical HARDI decomposition techniques. To address this important issue, we investigate the effect of the SNR under fixed parameters for -value and number of gradients and report in Figure 5. We observe that data with SNRs lower than 15 would produce very unreliable datasets, where the accuracy would drop to an angular error bigger than 10°. Smaller angles cannot be resolved accurately and most probably will not be detected as distinct fiber populations. It can also be seen that the effect of the number of gradient directions (at least at the level between 48 and 72) has much less of an effect on detection performance than the SNR level does. Take note that this is a simplified model of the diffusion process, where only two fiber populations are simulated. The scenario gets more complicated when more fiber populations interfere within a voxel. Increasing the number of gradients does not significantly improve the angular error in the case of SNR of about 20.
3.2. Real Data Analysis
For better appreciation of anatomical locations, we present the results by visualizing the recovered maxima, overlaid over an FA-map. To be able to observe the changes in the shape of the glyph profiles, in Figures 11, 12, 13, 14, 15,

Windows operating systems such that they can each agree who is going to be a local master browser and who will be local backup browsers. An election can be forced at any time. For example, let's assume that the CEO has finished his massage and reboots his server. As the server comes online, it will announce its presence and an election will take place to see if the PC in the spare parts department should still be the master browser.
When an election is performed, each machine broadcasts via datagrams information about itself. This information includes the following:
These values determine which operating system has seniority and will fulfill the role of the local master browser. (Chapter 6, Users, Security, and Domains, describes the election process in more detail.) The architecture developed to achieve this is not elegant and has built-in security problems. While a browsing domain can be integrated with domain security, the election algorithm does not take into consideration which computers become browsers. Thus it is possible for any machine running a browser service to register itself as participating in the browsing election, and (after winning) being able to change the browse list. Nevertheless, browsing is a key feature of Windows networking and backwards compatibility requirements will ensure that it is in use for years to come.
Yes, but most people who have done it have had their share of headaches. Spanning multiple subnets was not part of the initial design of Windows NT 3.5 or Windows for Workgroups. As a result, a Windows domain that spans two or more subnets is, in reality, the "gluing" together of two or more workgroups that share an identical name. The good news is that you can still use a primary domain controller to control authentication across each of the subnets. The bad news is that things are not as simple with browsing.
As mentioned previously, each subnet must have its own local master browser. When a Windows domain spans multiple subnets, a system administrator will have to assign one of the machines as the domain master browser. The domain master browser will keep a browse list for the entire Windows domain. This browse list is created by periodically synchronizing the browse lists of each of the local master browsers with the browse list of the domain master browser. After the synchronization, the local master browser and the domain master browser should contain identical entries. See Figure 1.14 for an illustration.
Sound good? Well, it's not quite nirvana for the following reasons:
If it exists, a primary domain controller always plays the role of the domain master browser. By Microsoft design, the two always share the NetBIOS resource type <1B>, and (unfortunately) cannot be separated.
Windows 95/98 machines cannot become or even contact a domain master browser. The Samba group feels that this is a marketing decision from Microsoft that forces customers to have at least one Windows NT workstation (or Samba server) on each subnet of a multi-subnet workgroup.
Each subnet's local master browser continues to maintain the browse list for its subnet, for which it becomes authoritative. So if a computer wants to see a list of servers within its own subnet, the local master browser of that subnet will be queried. If a computer wants to see a list of servers outside the subnet, it can still go only as far as the local master browser. This works because, at appointed intervals, the authoritative browse list of a subnet's local master browser is synchronized with the domain master browser, which is synchronized with the local master browser of the other subnets in the domain. This is called browse list propagation.
Samba can act as a domain master browser on a Windows domain if required. In addition, it can also act as a local master browser for a Windows subnet, synchronizing its browse list with the domain master browser.
The Windows Internet Name Service (WINS) is Microsoft's implementation of a NetBIOS name server (NBNS). As such, WINS inherits much of NetBIOS's characteristics. First, WINS is flat; you can only have machines named
fredor workgroups like CANADA or USA. In addition, WINS is dynamic: when a client first comes online, it is required to report its hostname, its address, and its workgroup to the local WINS server. This WINS server will retain the information so long as the client periodically refreshes its WINS registration, which indicates that it's still connected to the network. Note that WINS servers are not domain or workgroup specific; they can appear anywhere and serve anyone.
Multiple WINS servers can be set to synchronize with each other after a specified amount of time. This allows entries for machines that come online and offline on the network to propagate from one WINS server to another. While in theory this seems efficient, it can quickly become cumbersome if there are several WINS servers covering a network. Because WINS services can cross multiple subnets (you'll either hardcode the address of a WINS server in each of your clients or obtain it via DHCP), it is often more efficient to have each Windows client, no matter how many Windows domains there are, point themselves to the same WINS server. That way, there will only be one authoritative WINS server with the correct information, instead of several WINS servers continually struggling to synchronize themselves with the most recent changes.
The currently active WINS server is known as the primary WINS server. You can also install a secondary WINS server, which will take over in the event that the primary WINS server fails or becomes inaccessible. Note that there is no election to determine which machine becomes a primary or backup WINS server - the choice of WINS servers is static and must be predetermined by the system administrator. Both the primary and any backup WINS servers will synchronize their address databases on a periodic basis.
In the Windows family of operating systems, only an NT Workstation or an NT server can serve as a WINS server. Samba can also function as a primary WINS server, but not a secondary WINS server.
Whew! Bet you never thought Microsoft networks would be that complex, did you? Now, let's wrap up by showing where Samba can help out. Table 1.6 summarizes which roles Samba can and cannot play in a Windows NT Domain or Windows workgroup. As you can see, because many of the NT domain protocols are proprietary and have not been documented by Microsoft, Samba cannot properly synchronize its data with a Microsoft server and cannot act as a backup in most roles. However, with version 2.0. x, Samba does have limited support for the primary domain controller's authentication protocols and is gaining more functionality every day.

E-Verify Measure up for Debate
Thursday, February 5, 2009
As the negotiations for Obama's economic stimulus plan continue on Capital Hill, proponents of the E-Verify system are taking a stand.
E-Verify is a government program that checks a worker's immigration status against the Social Security Administration and the Department of Homeland Security. Immigration advocates believe using the E-Verify system lowers the rate of illegal immigrants becoming employed. Federally contracted workers, and several states across the nation, are already required to use E-Verify and face steep penalties if they are found to employ illegal workers.
The House version of the stimulus bill includes a provision for all companies or banks receiving funding from the federal government that requires them to participate in the E-Verify program.
But opponents of the provision insist that reporting errors from the SSA or Department of Homeland Security could result in thousands of wrongful terminations and essentially slow down the economy as a result.
However, proponents of the measure believe that any jobs available in the market should go to legal immigrants or American citizens, and using E-Verify will be a tool to insure that happens.

The People V. Leo Frank:
A teacher's guide to accompany the film by Ben Loeterman
"Almost a century after the fact, one of the most notorious criminal dramas in American history comes back to life as a documentary." —Atlanta Journal Constitution
The People v. Leo Frank, a 2009 film by Ben Loeterman Productions, vividly brings to life one of the most fascinating criminal cases in American history: the 1913 murder of a child laborer, Mary Phagan, and the trial and lynching of the Jewish factory supervisor accused of her murder, Leo Frank. Set against the backdrop of an American South struggling to shed its legacy of bigotry and xenophobia, The People v. Leo Frank is both a first-rate murder mystery and a compelling look at racial, religious, regional and class prejudices in the early years of the 20th century. View the movie trailer.
ADL is proud to present the Teacher's Guide to accompany The People v. Leo Frank. The guide provides instructional materials that help educators to explore the intersection of various forms of oppression and the complexity of bias incidents at the center of the Leo Frank case in four topic areas:
- Anti-Semitism and Religious Bigotry
- Racism and Race Relations
- Regional and Class Tensions
- The Power of the Press
Each topic area includes guided review of film clips with discussion questions, student readings, extension activities and research ideas, investigation of primary source materials, as well as correlation to national educational standards.
Students will emerge from their study of the Leo Frank case with an understanding of the ways in which anti-Semitism, racism and other social forces shaped life in the post-Reconstruction and Jim Crow South. More importantly, students will also increase their awareness about the dangers of stereotyping and bigotry in today's world, and the importance of speaking out against bias and prejudice of all kinds.
Read through some excerpts of the guide's discussion questions and watch the accompanying film clips. You can also download the entire Teacher's Guide using the form below.

According to Deng, the current computing power being used in Bitcoin mining operations is 8.23x10²² floating point operations per second (FLOPS for short), while the total computing power in the world is 1.2x10²³ FLOPS. According to these calculations, Bitcoin mining is consuming 17 percent of total global computing power, justifying the frequent accusations that Bitcoin mining is wasteful.
Matrix is seeking to reinvent mining algorithms by including AI into the equation through a Bayesian mining system that utilizes a Markov chain Monte Carlo algorithm (MCMC). Because these computations function similarly to traditional mining functions, they work well for Bitcoin mining.
As Deng argues, using AI, the computing power used to verify transactions on the Bitcoin network can be leveraged for other uses outside the world of cryptocurrencies.
One example he gave his scientific research -- a brain network simulation requires approximately 1018 FLOPS, while a complete human metabolic network simulation requires 1025 FLOPS.
According to Deng, other important non-crypto use cases that require massive computing power are chemical reaction simulations, medical diagnoses and complex finance modeling.
Intel recently filed a patent for a Blockchain-based system that also works to harness the energy used in cryptocurrency mining for scientific development - in this case particularly for genetic sequencing.
The BlockShow Asia conference this November included a number of innovative projects in addition to Matrix. 1,500 entrepreneurs and experts gathered at the event in Singapore to share and discover the latest developments in the industry.

The effects of process and outcome accountability on judgment process and performance
This article challenges the view that it is always better to hold decision makers accountable for their decision process rather than their decision outcomes. In three multiple-cue judgment studies, the authors show that process accountability, relative to outcome accountability, consistently improves judgment quality in relatively simple elemental tasks. However, this performance advantage of process accountability does not generalize to more complex configural tasks. This is because process accountability improves an analytical process based on cue abstraction, while it does not change a holistic process based on exemplar memory. Cue abstraction is only effective in elemental tasks (in which outcomes are a linear additive combination of cues) but not in configural tasks (in which outcomes depend on interactions between the cues). In addition, Studies 2 and 3 show that the extent to which process and outcome accountability affect judgment quality depends on individual differences in analytical intelligence and rational thinking style.

Soy sauce has become one of the most popular condiments in people's daily diets. The soy sauce of traditional brewing process in our country is incomparable in the color, aroma and taste of soy sauce produced in some developed countries. However, most of the brewing process is exposed to natural spaces, accompanied by the growth and reproduction of multiple microorganisms. So, how can we effectively remove bacteria from soy sauce? Here is a description of membrane separation technology.
In general, the solid content and viscosity of soy sauce are high, and it is very important to pretreat. Hollow fiber components should not be used. In this way, the processing flow is simplified, the production cost is reduced, and relatively considerable economic benefits are brought about. After the soy sauce is filtered, the color is improved, the soy sauce is clear and transparent, and the value is high. The retention rates of salt-free solids, reducing sugars, and pigments are all around 98%, and are in line with national product standards.
Process advantages of membrane separation
1. It has a simplified process flow and reduces operating costs.
2. It is automatically controlled, reliable in operation and balanced in product quality.
3. It has a long service life. The equipment has low comprehensive cost and high cost performance.
4. It has good acid resistance, alkali resistance, good anti-pollution performance and high separation precision.

It's hard to believe that 26 years before the outbreak of the American Civil War, 28 years before the Emancipation Proclamation, and 35 years before African Americans were allowed to vote, Oberlin College opened its doors to both white and black students alike to get a high quality, equal education. In 1835, It became the first University to regularly admit black students and hold a policy that it would accept any qualified student regardless of race. Oberlin was home to many ardent abolitionists and played a significant role in the Underground Railroad. Oberlin was a key stop and offered shelter to fugitive slaves on their escape to other northern states or Canadian territory. Not only was Oberlin the first college to regularly admit African-Americans but it became the first coeducational university in the country. In 1837, four female students enrolled with the rest of the male student body and 3 of them received their Bachelor of Arts degree in 1841. They are the first women ever to receive this type of degree. Oberlin College is truly a path setter in the way it laid the foundation for blacks and women to receive a higher education. It's also appropriate that the first African-American woman to receive a Bachelor's degree graduated from Oberlin in 1862.

Pink, associated with the Heart chakra and the product of the "marriage" of red and white, can aid in the healing of wounded intimate relationships. It has been observed that those who are drawn to pink are likely to readily display kindness, consideration and forgiveness. Decorators often use pink in bedrooms because it is evokes romantic feelings. Supposedly, the auras of newborn babies and their mothers are suffused with pink and its mother glows in the energy of the pink ray.
Pink encourages the perception of beauty, compassion, love, and purity of intent. Pink, associated with honesty, integrity and openness helps develop the capacity for self-respect and self-love in those individuals who tend to be perfectionists and to be very hard on themselves. When employed as an aid to meditation in can aid in the illumination of higher truths.
The differences between brown topaz and pink topaz can clearly be perceived both via thought-based analysis and feeling. These differences can then be used to help broaden one's understanding of the qualitative differences between the inner natures of gingergrass and palmarosa oils. In turn, this will aid in the determination of which of these oils is most relevant regarding the soul-nature of a specific individual.

Rolled zinc is a durable material
Rolled zinc products in building applications have a very long life due to the self-protecting property of zinc. In Europe, there are numerous examples of zinc roofs renovated after about 100 years of continuous service.
The reasons for such a long service time are now well understood :
|Stage 1||Stage 2|
The metallic zinc surface reacts with atmospheric oxygen (O2) in the presence of water (H2O) to form zinc hydroxide (Zn(OH)2).
The zinc hydroxide reacts with atmospheric carbon dioxide (CO2) to form zinc hydroxicarbonate (2ZnCO3.3Zn(OH)2) which is the main component of the patina.
The patina forms a layer which is compact, adhesive, insoluble in rainwater, and which will hinder any further exchanges between oxygen and zinc, thereby controlling the corrosion rate of rolled zinc and maintaining it at a low level.
Nevertheless, the durability of zinc can be reduced by some acid pollutants, which increase the corrosion rate. The main pollutant is sulphur dioxide (SO2). Sulphur dioxide reacts with the patina to form zinc sulphate (ZnSO3 + ZnSO4), which is soluble in water and is washed away by rain.
Sulphur dioxide is produced by some industrial plants, oil-fired central heating installations and road traffic. As a result, the corrosion rate is greater in an urban or industrialised area than in a rural environment.
Fortunately, since the 1970's, SO2 pollution of the atmosphere has been considered as a major environmental problem. Therefore, European and other legislators have strengthened legislation against this type of pollution. This has resulted in a general reduction of the concentration of SO2 in the atmosphere and an even more drastic reduction in particularly polluted sites such as cities or industrial areas.
As a result, the corrosion rate of rolled zinc was greatly reduced during the second half of the 20th century.
Today, the corrosion rate of rolled zinc is generally 1(¹) µm/year. With a typical initial thickness of 0.7 mm and a main corrosion rate of 1(¹) µm/an, we see that the life expectancy for rolled zinc is higher than a hundred years. The life expectancy of rolled zinc has increased over the last decades and will continue to increase over the years to come.

Getting the stock-images
As I was saying before the most important thing in a landscape photo manipulation is the right stock, so pick it carefuly. I've chosed the folowing stock:
Step 1
Open the first picture from the cosmos pack and place it in the left upper corner.
Step 2
Create a new layer. Select the brush tool smooth edges and paint some of the areas like in the image below. You can find the colors code next to the image.
Step 3
Open the next cosmos picture and place it in the right. Create a layer mask and eraseall th edges with a black brush with smooth edges.
Step 4
Open the third cosmos picture and place it at the bottom of the file. We just need the little planet from this one since we are going to put the earth there.
Step 5
Now press CTRL+J and duplicate this layer so the little planet should be in the left.
Step 6
This is it with the cosmos background for now, so let's create the earth. Open a new file. We are going to use a lot of stock pictures for this one so open the first two ones and place them like in the picture below.
Step 7
Open the next two pictures and place them like I did in the image below.
Step 8
Now create a mask for the sea picture and erase with a black brush all the edges.
Step 9
Open the cliff image and place it in the left corner, then got o the thitd image that we have opened and CTRL+J it and flip it horizontaly. We just need the bottom part from this picture.
Step 10
Create masks for this 2 new layers and erase all the edges.
Step 11
Create a new layer and fill it with light blue. Create a maks and erase some of the parts like in the image.
Step 12
Merge all the layers by pressing CTRL+ALT+SHIFT+E. Then go to File-Transform-Warp. Watch the picture below to see how to use the warp correctly.
Step 13
Drag the earth into the cosmos file. Place it like in the image. Create a mask and erase the top edges.
Step 14
Create a new layer. Load some cosmos brushes. You can fiind lots of greath brushes here or you can create your own brushes. Now place some stars in the lighter areas. This is a matter of taste so place as many as you wish.
Step 15
Next got o Filter-Render-Difference clouds. Create a mask and erase all the parts that are just to much - so the image will lock lighter.
Step 16
Cut the model out. Select a basic brush and paint some glitter next to her eye.
Step 17
Now we must create an action for the mesh wing. First draw a line similar to the one in the image below on a new layer. (1.) Then start recording the following things: Duplicate the line layer (press CTRL+J) and then transform the line (CTRL+T) by rotating the second line like in the image below (2.) After you're done with this stop the action.

Weather of Belgium
Belgium Weather / September 6, 2018
When you think of a European summer, you usually think of long, hot days on the French, Italian or Spanish coasts, not sheltering under an umbrella in the centre of Brussels.
With high rainfall, harsh winters and very average summers, Belgium has a bad reputation for its weather and deservedly so.
Wet Summers
Belgium has an annual average rainfall of 820 mm (32 in) that is fairly evenly distributed through the year, with a slight increase in the summer months. On average, they get around 200 days of rainfall each year. This is more than both Paris and London, both of which are renowned for their grey and drizzly days. This makes an umbrella or waterproof jacket essential items for any trip to Belgium.
The dampness can also make it feel much colder than it is, so even if you have dressed appropriately for the forecasted temperature it's probably a good idea to throw on an extra layer or two just in case.
The daily and monthly temperature variations are quite small, so unlike other European countries that oscillate between freezing cold and scorching hot, Belgium tends to go from mild winters to only-slightly-warmer summers. Average daily temperatures range from 3 degrees celcius in January to 18 degrees celcius in July.
Even at the height of summer, the temperature rarely exceeds 22 degrees celcius. Warm and sunny weather is not constant during summer and it is almost a surprise when the sun does come out. If you're lucky enough to get a few consecutive days of sunshine, be prepared for the locals to talk about nothing else. But even on warmer days, the evenings can still turn quite cool so you will probably need to pack a jacket or light jumper.
Wet Winters
From October, the temperature begins to drop quite rapidly. The winter months are chilly and wet, and rarely bring the same massive snowfalls that cover other parts of the continent. If it does snow, it will melt fairly quickly and become slush on the ground. Therefore it's a good idea to wear sturdy, thick-soled shoes in winter and watch your step on the quaint but surprisingly deadly cobble stone streets of Belgium's medieval towns.
Wet, but Safe
This moderate climate means that Belgium is subject to very few natural disasters. Flooding is a threat along rivers and in some areas of reclaimed coastal land. In November 2010, torrential rain across the country caused floods and mudslides, killing two people. However events of this scale are rare and very unlikely to affect most travellers.
To maximise your chances of getting good weather (but remember, it's never guaranteed in Belgium) May to September is the best time to visit, especially for hiking and outdoor activities. There is still a very high likelihood of rain but at least it won't be paired with freezing temperatures.
However, this is also peak tourist season, so it will pay to plan ahead and book accommodation in these areas before you arrive.


Sandwich Tern (Danny Sauvageau)
Have you noticed how newspapers and periodicals increasingly seize every opportunity for a headline ending "…say Scientists". It lends a spurious authority to any tenuous assertion, like "astronauts unlikely to find cheese on moon, say Scientists" (suggesting at least the faint possibility of some mature cheddar lodged in a crater). Or "Frooty-pops cereal may protect against ingrown toenails, say Scientists". To which the proper response is: "research reference please". But it seems 37.9% of people are actually prepared to believe this tendencious stuff… say Scientists.
But I digress. To the business in hand. The Sandwich Tern (Thalasseus sandvicensis) is a smart-looking medium-sized tern. Its clearest ID signifier among terns is a sharp black beak with a yellow tip. Also, its black legs helpfully distinguish it from other tern species that have orange legs.Sandwich Tern (Sandy Point), Abaco - Bruce Hallett
The origin of the name for this species is an unexpected one. The Thaleasseus (formerly Sterna) simply refers to the sea (Gk). The Sandwich part is more complicated. It's certainly nothing to do with a tasty filling for a sliced bread snack **. Other bird species such as Branta sandvicensis, an endemic Hawaiian goose, have the name because Hawaii was historically known as the Sandwich Islands. But Sandwich terns are not found there. In fact, the name comes from the town name of Sandwich, Kent UK (sand wic OE – 'trading post by the sea'). The ornithologist who first described the bird in 1787, John Latham, just happened to live there. (And how fortunate for ornithology that he did not come from Pratts Bottom, also in Kent).
Sandwich Tern, Abaco (Woody Bracey)
Sandwich terns have a wide range around the world. As the range map below show, the most significant breeding area is Great Britain and northern Europe. On Abaco, the birds are uncommon summer residents.

Like all the Thalasseus terns, the Sandwich tern plunge-dives for fish. I love the sight of diving terns. They hang high in the air as they scope out the water for fish, only to break free from the sky and smash down into the sea, often emerging with a silver prize. Here's a wonderful photo of one that missed its meal – and one that succeeded.
Sandwich Tern (Danny Sauvageau)Sandwich Tern (Danny Sauvageau) An endearing characteristic of these terns can be seen during their courtship display. The male will catch a fish, then offer it to the female. Her acceptance of the gift signals her readiness to approve the male as a suitable mate.
Of the 12 tern species recorded for Abaco most are summer residents, some of which breed on Abaco. The royals are the only permanent residents; and the Forster's are the only winter residents. The other 4 species are transient in migration, or vagrant (arctic tern).

As I have mentioned before, a very good source for easy ID to distinguish between different birds of the same family is to head off to BIRDORABLE. The drawings (cartoons!) may not be scientific, but they do highlight the most notable distinctions. Invaluable as a last resort. Or first resort, even! For similar-looking birds, compare the beaks and the legs. The composite below shows how simple it is.
Noisy neighbours? Put this short recording of a sandwich tern colony in the breeding season on a continous loop, and you have the makings of a powerful retaliatory weapon. They'll be out within a fortnight…

** The food we call a sandwich was named after the 4th Earl of Sandwich. He found eating while playing cards inconvenient, so asked his valet for two slices of bread, requesting "and squash a tern between them, if you'd be so very kind…" The Sandwich Islands were also named after his Lordship by Captain James Cook, as a compliment for financially supporting an expedition there, say Historians…

No, it's not Christmas in a beehive. Instead, each hexagon in this shifting honeycomb represents a gene. A computer program called GATE makes these movies by reading the data from an experiment and grouping genes that turn on (red) and off (green) at similar times. When researchers click on any part of the honeycomb, GATE connects them to databases brimming with more information about gene and protein activity. Such interaction helps biologists wrap their heads around the vast amount of data they and their colleagues have gathered. It also inspires new hypotheses in areas as diverse as stem cell differentiation and ecosystem evolution. Courtesy of the Ma'ayan Laboratory, Mount Sinai School of Medicine.

V. Food hygiene and sanitation in infants and young children: a paediatric food-based dietary guideline
Keywords: hygiene, sanitation, infants and young children
AbstractThis paper has three related aims. Firstly, it aims to profile the current food hygiene and safety needs of children under the age of five in South Africa. Secondly, to reflect the importance of domestic hygiene, access to water and sanitation in reducing the transmission of gastrointestinal pathogens while feeding infants and young children. And, thirdly, to highlight the need for collaboration between healthcare professionals and the local authorities who provide basic services. Food safety and hygiene needs for people living with HIV/AIDS (PLWHA) have been mainstreamed in the various sections addressed in this paper that underpin the importance of food safety and hygiene in immune-compromised individuals. The following topics have been covered: water and sanitation, food safety and hygiene, hand washing and personal hygiene, hygiene and sanitation for PLWHA, relevant primary healthcare strategies (e.g. oral rehydration solutions), rotavirus immunisation, and vitamin A and zinc supplementation. Additionally, the paper discusses relevant interventions to prevent diarrhoeal disease. This review utilises sourced references in both global and local evidence-based studies by conducting repeated literature searches via PubMed, the Cochrane Collaboration, Google Scholar, EBSCO Information Services and United Nations' agency documents, as well as the "grey" literature (theses, research reports and other non-indexed material). The main keywords "hygiene", "sanitation", "infants" and "young children" were used, in addition to other keywords and key phrases referred to in the text. On the basis of the literature review, it is proposed that the following message is tested for inclusion in the food-based dietary guidelines for infants and young children: "Hands should be washed with clean water and soap before preparing, feeding or eating, and after going to the toilet".

The aim of the study was to investigate the relationship between the concentration of psychrophilic bacteria, mesophilic bacteria and mold fungi in bioaerosols, and the number of new cases of type 1 diabetes mellitus (T1DM) in children.
Methods: Air samples from the Lubelskie and Pomeranian voivodeships in Poland were collected from January 2015 to December 2016 in winter, spring, summer and autumn. Thirty-three samples were collected in the Pomeranian and 27 in the Lubelskie voivodeship. The air samples were collected on the first day of each month at 1:00 pm for 10 mins at a height of 1.5 m above the ground. The number of mesophilic bacteria was detected after 24–48 hrs incubation at 37°C on tryptone soya agar (TSA; Merck, Darmstadt, Germany). The number of psychrophilic bacteria was detected after 72 hrs incubation at 22°C on TSA. The number of fungi was detected by a 5-day long incubation at 28°C on chloramphenicol yeast glucose agar.
Results: In the Lubelskie voivodeship, the mean concentration of psychrophilic bacteria was significantly higher than in the Pomeranian voivodeship (2739 vs 608 CFU/m3, respectively), the mean concentration of mesophilic bacteria was significantly higher (2493 vs 778/m3, respectively) and the concentration of fungi was significantly higher (3840 vs 688 CFU/m3, respectively). We also showed a statistically significant relationship between the number of children with recently diagnosed T1DM and the mean concentration of psychrophilic and mesophilic bacteria in the Pomeranian and Lubelskie voivodeships (P<0.001). Moreover, we found a significant relationship between the number of new cases of T1DM in children and the mean concentration of fungi in bioaerosols in the Lubelskie voivodeship (P<0.001), but not in the Pomeranian voivodeship (P=NS).
Conclusion: The results of our research showed that there is a higher concentration of microbial particles in the Lublin voivodeship. Therefore, we recommend changes in climate for children (trips to the sea, mountains, etc) as often as possible.

Strategic Planning of Technology Transfer.
Groff, Warren H.
Using the Ohio Technology Transfer Organization (OTTO) as its primary example, this paper offers a strategic planning perspective on technology transfer and human resources development. First, a brief overview is provided of the maturation of mission priorities and planning processes in higher education in the United States, followed by a definition of technology transfer as a means to facilitate economic development, increase productivity, and stimulate job growth. Next, several components of OTTO (a statewide network of postsecondary institutions providing small business and industry with the information, advice, and services essential to technology transfer) are described, along with other state and national efforts in the field. A strategic plan to accomplish technology transfer and human resources development is then presented within the framework of three components: (1) research and development; (2) delivery systems; and (3) evaluation. The research and development component is examined in terms of futurism, trend analysis, high technologies, modes of technology transfer, technology assessment, entrepreneurship, and community development. The delivery systems component is considered with reference to personnel and alternative forms of the electronic delivery of education and training. The process of evaluation is presented in terms of costs, capital planning, and management of the planning process. In a brief conclusion, the future of postsecondary education is linked to the degree to which it meets social needs. (HB)

Ed and Edd, But Not Eddy
Ed and Edd decided to build competing roller coasters. Ed built his roller coaster 40 feet high that will travel down on a straight slope. Edd built his roller coaster 40 feet high, but his travels down a curved slope (steep at the beginning, levels out at the end with no bumps).
If both cars are released at the same time (they cars are identical), which one will arrive at the bottom first?
 1. curved slope will win
 2. The curved slope will win because you will pick up more speed at the beginning.
 3. mike - are you sure about this? I spent a lot of time considering this (this happens to be right up my alley, as you may know by now), and I think I may disagree. you do in fact get more speed at the beginning, but you have a greater distance to travel, since you have to travel the length of the line, and if the line is curved, it will be longer (i.e. the shortest distance between two points is a straight line).
 Consider the following extreme example. Let's say that your "curved line" consists of a vertical drop for the full height, then a flat line going to the end, while the "straight line" coaster is just a linear slope between the start and end. We'll say that it's 45 degrees for simplicity (that is, length=height=h). If you crunch the numbers, it comes out that it takes slightly longer to get to the end of the "curved" coaster, unless I made a mistake.
 "Straight Line"
 distance to travel = d = h*sqrt(2)
 acceleration = a = g cos(theta) = g/sqrt(2)
 d = h*sqrt(2) = (1/2)*a*t^2
 t = 2*sqrt(h/g)
 "Curved Line"
 First Leg:
 distance = d = h
 acceleration = a = g
 d = h = 1/2*a*t1^2
 t1 = sqrt(2*h/g)
 final velocity = v = sqrt(2*g*h)
 Second Leg:
 distance = d = h
 acceleration = a = 0
 d = v*t2
 t2 = d/v = h/sqrt(2*g*h) = sqrt(h/(2*g))
 t = t1+t2 = (sqrt(2)+sqrt(1/2))*sqrt(h/g)
 since (sqrt(2)+sqrt(1/2))>2, the "curved" scenario takes longer, by my figuring. Anyway, it seems like this would hold true for all similar scenarios if it held true for this case, but I'm not sure about it.
 I bet this was a lot more than you bargained for on this question...sorry.
 4. As usual for me, I'm not sure. It's going to take me some time to figure this one out.
 At first glance, I would think it would matter how far you are dropping. Off the top of my head (I haven't worked my way through your math, yet) I can definitely see there would be a tipping point where the straight line would catch up to the curved line, but for a short drop, the curved line (I would think) would win.
 And, if there is a tipping point, I wonder what that would be.
 And, that all supposes that I'm right about the quick pick-up of speed.
 Let me work through your math and see what I can see.
 5. Alright, after trying my hand at some algebra, I think I came up with time on a curved track is (sqrt(2) + sqrt(2))*sqrt(h/g) which is bigger than time on a straight track 2*sqrt(h/g).
 If either of us is doing the math correctly, the straight line wins.
 Sorry about that.
 6. it's ok. I'm going to actually look at some Hamiltonian / Lagrangian techniques and see if I can solve this definitively with calculus of variations. you've piqued my curiosity. I'll get back to you.
 7. Mike,
 I crunched the numbers on one that slopes just a little more sharply than a straight line, then levels off at the bottom, and it is indeed faster. If you slope just a little more at the first, it is faster, but the extreme case I gave is slower, which means there is some maximization curve which will do it in the fastest time. Anyway, good question, even if you didn't realize it at the time ;-)
 9. Wow, that was totally not obvious to me. Very interesting though.
 I really wish I could say I knew it all along, but I'm guessing everyone here would know better by now!

Debug Process
To debug a mapping, complete the following steps:
 1. Create breakpoints.
 Create breakpoints in a mapping where you want the Integration Service to evaluate data and error conditions.
 2. Configure the Debugger.
 Use the Debugger Wizard to configure the Debugger for the mapping. Select the session type the Integration Service uses when it runs the Debugger. When you create a debug session, you configure a subset of session properties within the Debugger Wizard, such as source and target location. You can also choose to load or discard target data.
 3. Run the Debugger.
 Run the Debugger from within the Mapping Designer. When you run the Debugger, the Designer connects to the Integration Service. The Integration Service initializes the Debugger and runs the debugging session and workflow. The Integration Service reads the breakpoints and pauses the Debugger when the breakpoints evaluate to true.
 4. Monitor the Debugger.
 While you run the Debugger, you can monitor the target data, transformation and mapplet output data, the debug log, and the session log. When you run the Debugger, the Designer displays the following windows:
 - Debug log.
 View messages from the Debugger.
 - Target window.
 View target data.
 - Instance window.
 View transformation data.
 5. Modify data and breakpoints.
 When the Debugger pauses, you can modify data and see the effect on transformations, mapplets, and targets as the data moves through the pipeline. You can also modify breakpoint information.
The Designer saves mapping breakpoint and Debugger information in the workspace files. You can copy breakpoint information and the Debugger configuration to another mapping. If you want to run the Debugger from another PowerCenter Client machine, you can copy the breakpoint information and the Debugger configuration to the other PowerCenter Client machine.
The following figure shows the windows in the Mapping Designer that appears when you run the Debugger:
In addition to the mapping, the Debugger displays the debug log, session log, Instance window, and Target window.

 Packing at the Palace Museum and installation at the V&A
Journalists have expressed a great deal of interest in the way the robes were preserved. The garments look so pristine – they said. How are they stored in the Palace Museum?
Today we take it for granted that museum objects are kept in purpose-built storerooms, inside cupboards with environment control. But we must not forget that before the robes became historic objects they were clothes that were worn, not 'art' that was for display. The well-being of the robes was the duty of the Imperial Household Department staff. In days before the invention of air-conditioners and humidifiers the robes were protected from fluctuating temperature by sturdy wooden cupboards and chests. Insect-repelling incense was placed inside the furniture, and palace eunuchs regularly aired the clothes to prevent the build-up of mildew.
 Details of robes
But what about the 1911 Revolution? What about the two world wars? What about the Cultural Revolution? The journalists persisted. I of course do not know what happened during those turbulent years. Yet the fact that the robes have not suffered damage must mean that they had somehow escaped the notice of the Japanese invaders and the little red guards.
A few sceptical journalists suspected the exhibition to be a government initiative, aimed at boosting Sino-British relationship. Whereas that is not true, I was still bewildered at the way some people distrust their government. It is as if anything organized by the government has something sinister behind it. I murmured to one of the robes: "tell me, if you were sent to the UK not at the request of the V&A but at the request of Downing Street, would that make you less pure or less inspiring?" The robe, very wisely, remained silent, as it has done for the past 300 years.
In China it is the other way round. Anything organized or supported by the government is seen as good. Perhaps the Chinese understand that the ability to trust is a faculty too precious to throw away without a good reason. Once it is gone it would be very difficult to re-build.

Researchers at the University of Chicago just accidentally stumbled upon something they weren't even trying to make. While experimenting with some new ways to create glass, they accidentally created a whole new kind of it.
The experiment the researchers were performing involved vaporizing organic molecules in a vacuum and then layering them at a very specific temperature to form glass. But when they examined the way that light shone through it and found strange results. Initially they assumed their readings were a mistake but eventually found that the resulting material had a fairly regular molecular makeup, which is strange for glass.
Professor Juan de Pablo explained it this way in a press release about this discovery:
Randomness is almost the defining feature of glasses. At least we used to think so. What we have done is to demonstrate that one can create glasses where there is some well-defined organization. And now that we understand the origin of such effects, we can try to control that organization by manipulating the way we prepare these glasses.
What kind of applications does this glass have? It's unclear, but the optical qualities of this kind of glass are much different than traditional varieties. That means there's a lot to study. According to Pablo, "This is a new field of research and a class of materials that didn't exist before. So we're just at the beginning."
