Should You Have Workplace ID Cards if There's Already Security Personnel?
When securing your property there are several different approaches to keeping it safe. A well-managed building and security personnel can help a lot, however by using ID cards you not only increase safety but also gain flexibility. Now you may be questioning why ID cards are useful when you already have security personnel, so here are three reasons why.
It Supports Your Security Personnel
Without an ID system your security personnel have to keep track of everyone that enters your property; this takes a great deal of time and expense. For example without an ID system in place your security has to talk with everyone who enters the building, check their identification, and sign them into some type of record system every time they show up. With ID cards it's easy to identify who should be there and grant access to those who should have it.
ID Systems Are Versatile
>With a well implemented ID system you give your visitors and employees greater freedom to move about your property and do what they are paid to do. ID cards can range from the simple to the very complex allowing you to easily implement a system that fits your needs. Permanent ID cards can have a picture of the holder and special security measures, such as holograms, to identify the card as authentic. While simpler ID systems use paper IDs that allow access for short term visitors and then expire after a set period of time. Plus you can combine your ID card system with computer software to keep detailed records of who visited and when. No matter what system you use it allows you to keep track of visitors without overworking your existing security measures.
It Lets You Control Access
ID cards can do a lot more than just identify who should be in a building, as they can control who gets in at all. ID badges can easily be combined with security features to allow greater usability and add features. Proximity cards can be handed out with ID cards allowing you to not only identify who should be in your building but also controlling what parts of the building they can access. Proximity cards function much like key fobs allowing employees to open locked doors via a scanner system. This also cuts down on security work as they no longer have to guard such locked doors or control who can access them. This saves both time and money, and makes day to day operations easier to manage.
While security personnel are an essential part of having a safe property ID badges offer further safety and increased flexibility as well for your existing security systems. When selecting an ID card system to make use of you have several different choices available to fit a variety of businesses and properties. This variety of choices allows you to pick an ID card system that fits your needs and uses. When looking to buy ID card equipment you want to buy from an industry professional.

Scientists create epidermis that could replace animal testing
By Amanda Stewart,
Artificial epidermis grown by scientists in a lab could potentially replace animals in drug and cosmetic testing.
The findings of this study are published in the journal Stem Cell Reports.
According to The Daily Mail, scientists, in both the United Kingdom and the United States, have been able to produce fragments of epidermis (the outermost layer of skin) using stem cells.
The epidermis is in place in order to protect the body from the external environment. Until now, the engineers working on recreating the epidermis have been unable to create a layer of skin that is functional as a protective barrier.
They believe that in the near future these layers of skin grown in a lab could limit the suffering of animal testing, according to Science World Report.
"The ability to obtain an unlimited number of genetically identical units can be used to study a range of conditions where the skin's barrier is defective due to mutations in genes involved in skin barrier formation, such as ichthyosis (dry, flaky skin) or atopic dermatitis," said Theodora Mauro, a researcher from the study. "We can use this model to study how the skin barrier develops normally, how the barrier is impaired in different diseases and how we can simulate its repair and recovery."
These skin samples could also lead to more understanding of skin disorders, such as eczema.

Clustering of the values of a response variable and simultaneous covariate selection using a stepwise algorithm.
- Competence Center for Methodology and Statistics
In supervised learning the number of values of a response variable can be very high. Grouping these values in a few clusters can be useful to perform accurate supervised classification analyses. On the other hand selecting relevant covariates is a crucial step to build robust and efficient prediction models. We propose in this paper an algorithm that simultaneously groups the values of a response variable into a limited number of clusters and selects stepwise the best covariates that discriminate this clustering. These objectives are achieved by alternate optimization of a user-defined model selection criterion. This process extends a former version of the algorithm to a more general framework. Moreover possible further developments are discussed in detail.

Biography for
The Mandarin (Character)
from "Iron Man" (1994)
Warning! This character biography may contain plot spoilers.
Visit our Character Biography Help to learn more.
The Mandarin is a notable Super-Villain who first appeared in the 1964 comic "Tales of Suspense #50" (Written by Stan Lee)
BiographyThe Mandarin's parents, a Mongolian nobleman decended from Genghis Khan and a British aristocrat, died shortly after he was born. The Mandarin spent all of his inheritance training at science and martial arts. Doing so caused him to go broke at roughly the same time he reached adulthood. The Chinese government evicted him because he was too broke to pay his taxes. The bitter, broke, homeless, but extremely well trained Mandarin began to wander the earth. He found an alien space-ship during his wandering. He studied the ship to gain knowledge of advanced science, and stole rings he found within it. The Mandarin uses a combination of superhuman martial arts abilities, alien science, and the ten energy-blasting rings he found to wage a never-ending war on civilization.
Powers and abilitiesThe Mandarin possesses superhuman martial arts skills, such as channeling Chi into superhuman strength, performing superhumanly destructive karate-chops, and going for long periods of time without food or water by living on stored Chi.
The Mandarin is extremely educated in multiple scientific fields.
The Mandarin is a genius tactician and gifted strategist.
WeaponryThe Mandarin wields ten energy-blasting rings. Among the uses for these rings are creating illusions that allow him to attack while his enemy doesn't know what is real, trapping an enemy in ice allowing him to attack while the enemy can not move, and creating a tornado allowing him to attack while the enemy is dizzy. In conjunction with his superhuman martial arts abilities, these make him an extremely lethal warrior.
In Iron Man 3, the Mandarin is only an actor named Trevor Slattery, hired by Aldrich Killian to confuse everyone making people think he is the real super villain. He does not possess any superhuman martial arts skills or something similar to the comics. It is later revealed that Killian himself is the Mandarin.

Automated Target Recognition in Gigapixel Video
Agency / Branch:
DOD / USAF
The objective of the proposed program is to develop a long term image-based tracking camera system. Our goal is to allow fewer personnel to analyze and respond to threats detected in aerial video, making large format video useful in real time analysis. We propose to exploit long term 'contextual' information gathered over long periods of time over wide areas to improve tracking performance. Further, we provide identification and classification of thousands of simultaneous targets using both tracking information and previously gathered identity data. In the first phase, we propose to study three algorithms - short term tracking (0-30 seconds), medium term tracking (30 seconds - 1 hour), and long term tracking and identification (1 hour - 24 hours). ArguSight personnel have significant experience in large format imagery and video analysis, and are well qualified to address all parts of the work effort. We will be working with subcontractor Carnegie Mellon University (CMU, a premier computer vision research center.

Understanding ESG
Understanding an organisation's ESG aspects provides an in-depth exploration of non-financial risks that may adversely affect organisational performance. Furthermore, considering the different ESG aspects enable value creation through, firstly, recognising the gaps that are present in their ESG business practices and, secondly, closing the gaps to maximise the value creating opportunities inherit in them.
While ESG aspects are typically referred to as non-financial elements, they can have a direct impact on the financial performance of an organisation. Stakeholders, from customers to investors, are increasingly making their decisions on the ESG aspects of an organisation. This has a direct financial impact on revenue and the cost of capital.
Studies have found that organisations with robust ESG practices are more likely to have a lower cost of capital, fewer accounts of corruption, and reduced volatility. In addition, those organisations that were found to have poor ESG practices were more likely to have a higher cost of capital and increased volatility due to disruptions along their supply chains, their operating environments and/or caused by extreme weather events, as well as possible liabilities, or legal compliance issues.
While it might be simple to understand the different ESG elements of organisations and the subsequent benefits, the process of identifying and benchmarking organisational practice against ESG best practices has previously been a costly, time-consuming process.
This time-consuming process has been optimised through a collaboration between Mazars and Kudos One. We have developed a simple but effective tool and thus, increased the accessibility for organisations to engage with their ESG practices.
Your Mazars ESG Awareness assessment will simplify the first steps into becoming a more sustainable organisation, while simultaneously analysing the risks and opportunities at the forefront of your business practices.
After the completion of an ESG Awareness assessment, we provide a report that discusses an organisation's current awareness levels to ESG elements and the gaps in organisational practices. Additionally, pragmatic solutions are provided to close the relevant gaps while maximising value.

In economics, a positional good is a product or service whose value is at least in part (if not exclusively) a function of its ranking in desirability by others, in comparison to substitutes. The extent to which a good's value depends on such a ranking is referred to as its positionality.
The term was coined by Fred Hirsch in 1976. The broad theme of Hirsch's book, in which he developed his theory of positional goods, was, he told the New York Times, that material growth can "no longer deliver what has long been promised for it - to make everyone middle-class". This important concept explains why, as economic growth improves overall quality of life at any particular level, doing "better" than how your grandparents lived does not translate automatically into doing "well", if there are as many or more people ahead of you in the economic hierarchy. For example, if you are the first in your family to get a college degree, you are doing better. But if you were at the bottom of your class at a weak school, you may find yourself less eligible for a job than your grandfather, who was only a high school graduate. "The value to me of my education - the satisfaction I derive from it - depends upon how much education the man ahead of me in the job line has."
Hirsch's contribution is becoming more notable as the Great Recession multiplies the number of college educated but poorly employed graduates, and probably explains why he would be referenced in a television situation-comedy: "There's an economic concept known as a positional good in which an object is only valued by the possessor because it's not possessed by others. The term was coined in 1976 by economist Fred Hirsch to replace the more colloquial, but less precise neener-neener."
Positional goods often earn economic rents or quasi-rents. Examples of positional goods include high social status, exclusive real estate, a spot in the freshman class of a prestigious university, a reservation at the "hottest" new restaurant, and fame. The measure of satisfaction derived from a positional good depends on how much one has in relation to everyone else.
Competitions for positional goods are zero-sum games because such goods are inherently scarce, at least in the short run. Attempts to acquire them can only benefit one player at the expense of others. By definition, every person cannot be the most educated, the most skilled, or elite, in the same way that every person cannot be a star athlete: all of those terms imply a separation or superiority over other people.
Land (in the economic sense) is similar to positional goods in that it cannot be created, and land rent arises largely because of a parcel's ranking in desirability against other plots. However, land is valued at least in part for its absolute contribution to productivity, which does not derive from its relative ranking. Thus, some economists (such as Hirsch) include 'land' in positional goods, while others (such as Robert H. Frank) only include goods which are valued specifically because of their relative quality.
In general, positional goods cannot be created, only redistributed, while material goods can be created with time and effort. However, most goods have both a positional and a material component. Fast cars may be considered to be inherently scarce because one's perception of a car's speed depends on its relation to other vehicles, but there is still an absolute value attached to satisfaction gained from the speed at which a car can travel; it can be considered as having a positional aspect in that only some cars can be the fastest. Because a car is a complex product made of many other materials, some of which (such as steel) are limited in supply and some which (such as leather) are renewable, they may instead be considered Veblen goods.
Positional externalities
Some economists, such as Robert Frank, argue that positional goods create externalities, or a so-called "arms race" for goods that might boost one's social status relative to others. This phenomenon is clearly wasteful; thus, it is argued, government can improve social welfare by imposing high luxury tax on certain luxury goods to correct for this externality and mitigate the social waste.
However, in some cases it may be less clear that such government intervention is warranted in response to these externalities. For example, government spending may be administered by players are equally motivated by positional goals. Furthermore, in certain cases, such government actions can potentially impede improvements in living standards and innovation. Technological advance itself is possible in part because wealthy individuals are willing to purchase new and untested goods. There is a certain experimentation and risk that accompany luxury goods, and if they are found to be useful they may eventually be mass produced and made affordable to the common person: one era's luxuries are another's commonplace goods. In short, the negative positional externality is often compensated by the public goods of infant industry effects and research and development. Ultimately, any such positive effects of these goods would need to weighed against the negative positional effects to determine the magnitude of any consumption taxes placed on them.

You could make the dropdown box editable, then when the user starts typing the control suggests colors from the list. For advanced users the box should accept color values in hex.
share|improve this answer
If I want a custom colour, I have to select the star, and then enter in the colour value. You are adding an extra step for no benefit, and adding something that is not very clear.
I would instead treat the dropdown as a shortcut to a defined colour which modifies a text field which can represent a hex colour, or a code colour.
That way it is clean and simple to use, and makes it as fast as possible.
Here is an mockup of what I mean:
enter image description here
If you have the ability, I would also make the colour block a link to a colour palette with relevant colours. This would also act as a shortcut to change the hex value or code value depending on what is most applicable. Something similar to this:

Thank you for your answer, my mistake - I explained what I want to do in a very brief way. I can't go away from code field, this is the domain-specific area of app. It must be there. Also there are other different GUI elements: width pickers, style pickers, text editors and so on that will have two different input modes. Color is the only example. Hence, I need this "trigger" to switch on the "input code mode". What is the most intuitive way for end-user to perform it? End-users are aware of code input and app functionality. – Steve Mar 7 '13 at 18:22
_USER_ could you please explain how the 4th example shown would not work? You could just not use hex codes, but keep the text area for domain specific code. – JohnGB Mar 7 '13 at 18:43

The finest soups, roasts and sweet buns were daily fare in the Salzburg villa. Johanna Raudaschl lived there almost as part of the family, as she recalls vividly in her memoirs. She began collecting her recipes - for both food and life - where she grew up, an illegitimate child, in the modest rural surroundings of the Salzkammergut [Austria's lake district]. Her grandmother taught her the secrets of cooking and baking. During her apprentice years she refined her culinary skills, and the Trapp family then benefited from her resourcefulness in the kitchen. She handed down her treasured recipes to her grand-daughter Irmgard Wohrl, who tried them out and now, together with journalist and biographer Caroline Kleibel, reveals them in the context of the moving story of Johanna Raudaschl's life. The grandmother of the author Irmgard Wohrl became close with the singing family known from the worldwide renowned Musical Sound of Music. This book reveals stories about the Trapp-Family that were never told before.

Perambulator or Pram in short, was invented by an English garden architect named William Kent in 1733. Kent was commissioned by the Duke of Devonshire to create a transportation device for his children. The first incarnation was a shell shaped basket on wheels meant to be pulled by a small pony or goat. Real prams appeared in the 1800′s and around 1870 bassinets were added.
Even though the Victorian prams were elegant and beautiful but in reality they were unstable and not very safe. They were often made of wood and held together by expensive brass joints. Not until 1965, the first stroller with aluminum frames was designed by an aeronautical engineer named Owen Maclaren which spurred an industry and evolved into today's modern strollers.


What is sailing?
Sailing is a sport that uses wind to power sails and propel the sailing boat forward. There are two types of sailing – racing and cruising. Racing is a type of yachting you will identify from the Olympics, however cruising is more of a recreational activity.
How can I sail?
Sailability is a national program developed through the Royal Yachting Association that enables people with disabilities to try sailing and take part regularly. You don't need to be able-bodied, or even a strong swimmer to get into sailing. The variety of approved Sailability sites will have boats and facilities to cater for everyone.

Let's suppose I'm working with some set of functions $f_k(n)$. $f_1(n)$ is essentially the root of my functions, and could be nearly anything, and then $f_k(n) = (f_1(n) * f_{k-1}(n))$ for some convolution $*$ that won't be described here. $f_k(n)$ takes non-negative integers and yields reals. $f_k(n)$ has as a given the following properties.
1) $f_0(n) = 1$
2) ($f_j(n) * f_k(n)) = f_{j+k}(n)$. This mirrors, of course, the usual rules about raising numbers to powers ($x^j \cdot x^k = x^{j+k}$). More broadly, $a f_j(n) * b f_k(n)) = (ab)f_{j+k}(n)$
3) $f_k(n)$ structurally must be 0 once $ k > \log n$, or thereabouts.
4) * is both associative and commutative.
Suppose I can't guarantee almost anything else useful about $f_k(n)$, because it's such an irritable function. Integration and derivation don't work. $f_k(n) \cdot f_k(m)$ and $f_k(n) + f_k(m)$ are manually computable but in wildly unpredictable ways, and $f_k(n+m)$ has no obvious or easy relationship to $f_k(m) + f_k(n)$. There are no guarantees about values being greater or less than other values in any direction.
(I realize that might be insufficiently precise, so let me know if there needs to be any clarification)
So here's my question. Only given the four properties above, which identities from the world of power series will still be valid, if we replace the usual powers of x with my convolution here? Or, more generally, is there a way to tell which identities will be valid?
I know by hand that many series identities seem to work regardless of the nature of $f_1(n)$ - so, for example, if we define $cosf(n) = 1 - \frac{f_2(n)}{2!}+\frac{f_4(n)}{4!}-\frac{f_6(n)}{6!}+...$, and do something similar for $sinf(n)$, then $cosf(n)*cosf(n) + sinf(n)*sinf(n) = 1$, if $cosf(n)*cosf(n)$ is taken to mean the term-wise convolution of its power series with itself.
An awful lot of other series relationships seem to work from this perspective.
On the other hand, $sinf(n+ \frac{\pi}{2})$ usually isn't $cosf(n)$ (for the various $f_1(n)$ I'm working with). Trig identities dealing with things like half angle formulas I've tried don't generally work, either.
Is there an easy way for me to tell which power series relationships will still be valid? Am I stumbling on an obvious and well-covered area of research here? It would be really handy for me if I were...

I don't see the relevance of property 4) especially since you haven't described what set $f_k(n)$ takes values in. What seems to be much more relevant is the question of whether * is associative and/or commutative. – Qiaochu Yuan Nov 17 '11 at 22:59
* is both associative and commutative. I updated my question and changed property #4 to say as much... And $f_k(n)$ operates operates on non-negative integers and produces reals. I'll add that to my question too. – Nathan McKenzie Nov 17 '11 at 23:28
It sounds like you are looking for some kind of functional calculus, i.e. a way of calculating $P(f_1)$ for any polynomial $P$ (which is just trival algebra) or, more generally, for $P$ an analytic function on some domain. If your space of functions were, for example, a Banach algebra, then you could use the holomorphic functional calculus for Banach algebras. If your space is not a Banach algebra, then you need to specify further topological properties; e.g. in what sense does the series for $\cos f_1$ converge? You definitely need some kind of extra analysis. – Zen Harper Nov 18 '11 at 3:45

Example sentences for: detritus-based
How can you use "detritus-based" in a sentence? Here are some example sentences to help you improve your vocabulary:
 - Growth and survival may thus be affected by habitat size, which varies greatly among small aquatic habitats [ 23 24 31 36 ]. There is a positive relationship between size, or volume, of the habitat and species richness, and between volume and growth responses of individual species [ 16 23 24 25 31 37 ]. Levels of water and resources may be important cues to ovipositing females, with resulting impacts on individuals and communities [ 9 16 38 39 ]. Oviposition site selection is an important variable affecting survival and development of non-dispersing larvae, and large volumes may be preferred by females laying eggs in aquatic environments due to increased stability and decreased risk of drought [ 29 39 ]. However, allochthonous plant material from surrounding terrestrial areas is the major input of energy resources to many freshwater detritus-based food webs, and resource quantity in these habitats is highly heterogeneous and dependent on location of the habitat relative to resource inputs [ 14 40 ]. Clearly, the choice of habitat by ovipositing C pipiens females will have growth and survival consequences for offspring.
 - The interaction we found between habitat size and food abundance is consequential for ecology of the organisms within, and there may be a complex relationship between habitat size, habitat drying (which changes volume when it occurs), and resources [ 30 32 ]. For instance, leaf litter resources are often limiting to organisms in aquatic detritus-based communities [ 11 15 22 32 33 ]. Resources in the form of leaf litter are consumed by microbes, which are then consumed by mosquito larvae, along with small particulate organic matter [ 22 ]. When litter abundance is high, microbial growth is also high (CJ Paradise, personal observation), due to both high levels of resources and substrate for microbes to grow on.

When you're strolling in your home city, and you see someone with pull out a map, you can be pretty sure you're looking at a tourist. But a new study suggests that a map-like spatial orientation is layered on top of people's understanding of even highly familiar places. In other words, you may not have a map stashed in a fanny pack, but you can't escape the way of looking at the world that maps tutor us in. From a new study in Psychological Science:
"We examined how a highly familiar environmental space—one's city of residence—is represented in memory. Twenty-six participants faced a photo-realistic virtual model of their hometown and completed a task in which they pointed to familiar target locations from various orientations. Each participant's performance was most accurate when he or she was facing north, and errors increased as participants' deviation from a northfacing orientation increased…. Although participants recognized familiar local views in their initial locations, their strategy for pointing relied on a single, north-oriented reference frame that was likely acquired from maps rather than experience from daily exploration. Even though participants had spent significantly more time navigating the city than looking at maps, their pointing behavior seemed to rely on a north-oriented mental map."

Fresnel Zone Plates (FZPs) are widely used in many areas, such as optics, microwaves or acoustics. On the design of FZPs, plane wave incidence is typically considered, but that is not usually the case in ultrasounds, especially in applications where a piston emitter is placed at a certain distance from the lens. In these cases, having control of the focal distance is very important, and with the usual Fresnel equation a focal displacement from the theoretical distance is observed due to the plane wave supposition. In this work, a comparison between FZP with plane wave incidence design and FZP with point source design in the case of piston emitter is presented. Influence of the main parameters of the piston in the final focalization profile has been studied. Numerical models and experimental results are shown, and they prove that when spherical wave incidence is considered for the piston case, it is possible to have a fine control of the focal distance in comparison with the classical design method.
Obesity is a low-grade inflammatory disease and may lead to health problems such as hypertension, dyslipidemia, diabetes. It is also associated with important risk factors for cardiovascular diseases. This requires the detailed evaluation of obesity, particularly in children. The aim of this study is to enlighten the potential associations between lipid ratios and obesity indices and to introduce those with discriminating features among children with obesity and metabolic syndrome (MetS). A total of 408 children (aged between six and eighteen years) participated in the scope of the study. Informed consent forms were taken from the participants and their parents. Ethical Committee approval was obtained. Anthropometric measurements such as weight, height as well as waist, hip, head, neck circumferences and body fat mass were taken. Systolic and diastolic blood pressure values were recorded. Body mass index (BMI), diagnostic obesity notation model assessment index-II (D2 index), waist-to-hip, head-to-neck ratios were calculated. Total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDLChol), low-density lipoprotein cholesterol (LDLChol) analyses were performed in blood samples drawn from 110 children with normal body weight, 164 morbid obese (MO) children and 134 children with MetS. Ageand sex-adjusted BMI percentiles tabulated by World Health Organization were used to classify groups; normal body weight, MO and MetS. 15th-to-85th percentiles were used to define normal body weight children. Children, whose values were above the 99th percentile, were described as MO. MetS criteria were defined. Data were evaluated statistically by SPSS Version 20. The degree of statistical significance was accepted as p≤0.05. Mean±standard deviation values of BMI for normal body weight children, MO children and those with MetS were 15.7±1.1, 27.1±3.8 and 29.1±5.3 kg/m2, respectively. Corresponding values for the D2 index were calculated as 3.4±0.9, 14.3±4.9 and 16.4±6.7. Both BMI and D2 index were capable of discriminating the groups from one another (p≤0.01). As far as other obesity indices were considered, waist-to hip and head-to-neck ratios did not exhibit any statistically significant difference between MO and MetS groups (p≥0.05). Diagnostic obesity notation model assessment index-II was correlated with the triglycerides-to-HDL-C ratio in normal body weight and MO (r=0.413, p≤0.01 and r=0.261, (p≤0.05, respectively). Total cholesterol-to-HDL-C and LDL-C-to-HDL-C showed statistically significant differences between normal body weight and MO as well as MO and MetS (p≤0.05). The only group in which these two ratios were significantly correlated with waist-to-hip ratio was MetS group (r=0.332 and r=0.334, p≤0.01, respectively). Lack of correlation between the D2 index and the triglycerides-to-HDL-C ratio was another important finding in MetS group. In this study, parameters and ratios, whose associations were defined previously with increased cardiovascular risk or cardiac death have been evaluated along with obesity indices in children with morbid obesity and MetS. Their profiles during childhood have been investigated. Aside from the nature of the correlation between the D2 index and triglycerides-to-HDL-C ratio, total cholesterol-to-HDL-C as well as LDL-C-toHDL-C ratios along with their correlations with waist-to-hip ratio showed that the combination of obesity-related parameters predicts better than one parameter and appears to be helpful for discriminating MO children from MetS group.
Obesity, a disease associated with a low-grade inflammation, is a risk factor for the development of metabolic syndrome (MetS). So far, MetS risk factors such as parameters related to glucose and lipid metabolisms as well as blood pressure were considered for the evaluation of this disease. There are still some ambiguities related to the characteristic features of MetS observed particularly in pediatric population. Hormonal imbalance is also important, and quite a lot information exists about the behaviour of some hormones in adults. However, the hormonal profiles in pediatric metabolism have not been cleared yet. The aim of this study is to investigate the profiles of cortisol, insulin, and thyroid hormones in children with MetS. The study population was composed of morbid obese (MO) children without (Group 1) and with (Group 2) MetS components. WHO BMI-for age and sex percentiles were used for the classification of obesity. The values above 99 percentile were defined as morbid obesity. Components of MetS (central obesity, glucose intolerance, high blood pressure, high triacylglycerol levels, low levels of high density lipoprotein cholesterol) were determined. Anthropometric measurements were performed. Ratios as well as obesity indices were calculated. Insulin, cortisol, thyroid stimulating hormone (TSH), free T3 and free T4 analyses were performed by electrochemiluminescence immunoassay. Data were evaluated by statistical package for social sciences program. p<0.05 was accepted as the degree for statistical significance. The mean ages±SD values of Group 1 and Group 2 were 9.9±3.1 years and 10.8±3.2 years, respectively. Body mass index (BMI) values were calculated as 27.4±5.9 kg/m2 and 30.6±8.1 kg/m2, successively. There were no statistically significant differences between the ages and BMI values of the groups. Insulin levels were statistically significantly increased in MetS in comparison with the levels measured in MO children. There was not any difference between MO children and those with MetS in terms of cortisol, T3, T4 and TSH. However, T4 levels were positively correlated with cortisol and negatively correlated with insulin. None of these correlations were observed in MO children. Cortisol levels in both MO as well as MetS group were significantly correlated. Cortisol, insulin, and thyroid hormones are essential for life. Cortisol, called the control system for hormones, orchestrates the performance of other key hormones. It seems to establish a connection between hormone imbalance and inflammation. During an inflammatory state, more cortisol is produced to fight inflammation. High cortisol levels prevent the conversion of the inactive form of the thyroid hormone T4 into active form T3. Insulin is reduced due to low thyroid hormone. T3, which is essential for blood sugar controlrequires cortisol levels within the normal range. Positive association of T4 with cortisol and negative association of it with insulin are the indicators of such a delicate balance among these hormones also in children with MetS.
Obesity is an abnormal physical condition where an increased and undesirable fat accumulates in the human body. Obesity is an international phenomenon. In the present study, 12 schools were randomly selected from each district considering the areas i.e. Elite Private Schools in the private sector, Government schools in urban areas and Government schools in rural areas. Interviews were conducted with male students studying in grade 5 to grade 9 in each school. The sample size was 600 students; 300 from Faisalabad district and 300 from Rawalpindi district in Pakistan. A well-structured and pre-tested questionnaire was used for data collection. The calibrated scales were used to attain the heights and weights of the respondents. Obesity of school-going children depends on family types, family size, family history, junk food consumption, mother's education, weekly time spent in walking, and sports facility at school levels. Academic performance, physical health and psychological health of school going children are affected with obesity. Concrete steps and policies could minimize the incidence of obesity in children in Pakistan.
Medical, social, and economic relevance of osteoporosis is caused by reducing quality of life, increasing disability and mortality of the patients as a result of fractures due to the low-energy trauma. This study is aimed to examine the associations of metabolic syndrome components, bone mineral density (BMD) and trabecular bone score (TBS) in menopausal women with non-vertebral fractures. 1161 menopausal women aged 50-79 year-old were examined and divided into three groups: A included 419 women with increased body weight (BMI - 25.0-29.9 kg/m2), B – 442 females with obesity (BMI >29.9 kg/m2)i and C –


Risk analyses
Technology is evolving rapidly. What is the solution for the future today may be outdated the day after tomorrow. The Ingenium Risk Analysis team uses sensitivity analysis to map out the future risks of an energy project and proposes flexible solutions that are future-proof.
This flexibility can cover various aspects. For example, the fuel used - and the cost price evolution, availability, government support - is a crucial factor in the TCO for a particular energy solution. For example, heating a building solely on biogas carries a risk if the price of gas were to rise sharply in the future. However, heating networks are future-proof. While they usually use the recovery heat from waste plants today, in the future, they may also be fed by another heat source.
Another parameter is the possibility of renovating, repairing or expanding the installation in the future. Especially in large and complex projects, such as hospitals or buildings that are delivered as hulls, it is important to take account of functional changes and evolutions in the building volume during the initial design of the technical installations.
The concepts and scenarios proposed by Ingenium always take possible risks and evolutions into account. Calculating fluctuations in the price of raw materials or maintenance and scenarios for the evolution of the buildings from the start makes a project future-proof.

Before a baby can talk, he or she relies on non-verbal cues, especially facial expressions, to communicate. Babies also mirror those cues, and in so doing, discover the emotions the cues are attached to. In a recent study published in the Journal of Basic and Applied Social Psychology researchers from the University of Wisconsin scientists evaluated over 100 kids and found that that six and seven-year-old boys who had heavily used pacifiers were worse at mimicking emotions expressed by faces on a video. They also interviewed more than 600 college students and discovered that college-age men whose parents reported they had relied on pacifiers scored lower on tests measuring empathy and the ability to evaluate the moods of others. For girls and young women, the researchers found there was no difference in emotional maturity based on pacifier use.

Smartphones to help fight stress from noise
traffic on Melbourne freeway
Crowd sourcing data to identify urban noise hotspots could combat stress and improve productivity, say researchers (Source: Flagstaffotos)
Researchers from CSIRO and the University of New South Wales, built the program called Ear-Phone, using existing smartphone technology, to provide more detailed noise profile maps of cities, and help identify noise hotspots.
Noise pollution has been linked to stress in modern day life, with health effects including sleep disruption, hearing impairment, and psychological damage, impacting negatively on productivity
"This information is very important for town planning - if you want to build a school, and for real estate markets [and] buyers choosing the area they want to live in," says the study's lead author Dr Rajib Rana from CSIRO's Autonomous Systems Laboratory.
Rana says Australia does not actually measure ambient noise levels but in the United Kingdom noise maps are produced every five years.
However, he says, these don't measure noise levels directly but are based on models of traffic densities and the noise reflectivity off buildings. They also need to consider changes in levels throughout the day and night, and over small distances.
Rana says such existing methods of determining the noise distribution around a city is a very expensive process.
"Just think of the geographical extent of a city and covering every street," he says.
A better way
"We thought we could use samples from mobile phones as a crowd sourcing method of determining noise levels," says Rana, adding the modern smartphone already has sensors capable of collecting the data required.
"Just think of the built-in sensors [already] fitted to smartphones, such as accelerometers, gyroscopes, proximity sensors, light intensity monitors. Some even have temperature and humidity sensors," says Rana.
Smartphones also provide a location and time stamp to show exactly where and when the measurement was taken.
Rana and colleagues needed to develop an algorithm that records only useful measurements of ambient noise, and not other sounds like conversations, or keys jangling in bags, which could distort readings.
Initial tests were carried out on the streets of Brisbane, and readings were confirmed using commercially available sound meters.
Best results
The authors found the best results were obtained when people were outdoors, with the phone in their hand. Readings were far less accurate inside vehicles, or when the phones were in a bag or case.
"We only want to sample when the phone's in your hand, so the program determines if it's in a bag, pocket or case, by using its light monitor, accelerometer and proximity sensors, to determine its position and unwanted data can then be discarded," says Rana.
"GPS readings are used to determine movement below 6 kilometres per hour, which is the average the speed of the person walking, and a valid GPS signal means they're outdoors."
The research reported on the pre press website, indicates the program can detect the phone's position with an accuracy of 84 per cent.
The noise level and GPS co-ordinates are then sampled every minute and stored along with the location and time, before being uploaded to the database when a free Wi-Fi connection is detected.
According to Rana, the next challenge is to develop a sustainable incentive mechanism to get people motivated to participate.

Mutual exclusion for uniprocessors
journal contributionposted on 01.03.1999, 00:00 by Brian N. Bershad
Abstract: "We discuss and evaluate four mutual exclusion primitives appropriate for uniprocessors: memory interlocked instructions, software reservation, kernel emulation and restartable atomic sequences. A restartable atomic sequence is a code fragment that, if interrupted, is resumed by software at the beginning of the sequence, guaranteeing that the sequence is eventually executed to completion atomically.We describe two implementations of restartable atomic sequences for the Mach operating system, and show that restartable atomic sequences perform significantly better than either kernel emulation or software reservation, making them an attractive alternative for use on uniprocessors that do not support atomic read-modify-write instructions. Further, on many processor architectures that do support such instructions, we show that restartable atomic sequences can have better performance. We show that improving the performance of low-level mutual exclusion mechanisms can have a substantial effect on application performance."

Effector-triggered versus pattern-triggered immunity: how animals sense pathogens.
Publication TypeJournal Article
AuthorsStuart, LM, Paquette N., and Boyer L.
AbstractA fundamental question regarding any immune system is how it can discriminate between pathogens and non-pathogens. Here, we discuss how this discrimination can be mediated by a surveillance system distinct from pattern-recognition receptors that recognize conserved microbial patterns. It can be based instead on the ability of the host to sense perturbations in host cells induced by bacterial toxins or 'effectors' that are encoded by pathogenic microorganisms. Such 'effector-triggered immunity' was previously demonstrated mainly in plants, but recent data confirm that animals can also use this strategy.

Not at home? Alexa can greet visitors for you on your Ring doorbell
The benefits of a smart video doorbell are numerous and obvious. When you aren't home, you can still respond to visitors and provide instructions for deliveries. The downside is that you have to be near your phone and not currently busy in order to respond to visitors, so what happens when you're in the middle of an important conversation or driving? Thanks to a new feature called Smart Responses, Alexa can greet visitors for you. Alexa's reach continues to grow beyond just being a voice for Amazon Echo smart speakers and displays.
There are three main Smart Responses: Quick Replies, Alexa Greetings, and Motion Warnings. It's worth pointing out that Alexa Greetings is the only smart response that is Alexa powered.
Quick Replies is a solution for those times when someone shows up at your door and you can't — or you just don't want to — answer. When someone comes to the door, you can choose from six preset responses, including "Please leave the package outside," "Hi, we'll be right there!" or "If you'd like to leave a message, you can do so now." This feature has already begun to roll out and will be available on Ring Video Doorbell models, with the exception of the Ring Video Doorbell Wired.
Alexa greetings turn your doorbell into a sort of smart concierge. It can greet visitors for you and provide contextual responses based on their answer. For example, Alexa might ask if a visitor wants to leave a message or what the purpose of their visit is. If the response includes the word "package," Alexa can ask if the packages require a signature and inform the delivery person where to drop the packages. It's a useful tool for when you're away from home but you still want to leave information for visitors.
One of the Smart Responses, Motion Warnings, acts as a deterrent to anyone with less than honorable intentions. As soon as the doorbell detects motion, it chimes in with the message: "Warning, you are now being monitored and recorded by Ring." It functions in much the same way as a yard sign for a security system. If a potential burglar knows they are being watched, they're more likely to leave.
These new Smart Responses make the Ring lineup of doorbells even more useful, all while adding another layer of intelligence to Alexa's capabilities.

There are relatively few volcanoes in the Indian Ocean, most natably the hot-spot volcanoes of Piton de la Fournaise on La Réunion island and Karthala volcano on the Comores.
The first reported eruption of the region was from a written account of an eruption of Karthala volcano between the 10th and 12th century, the next recorded eruption was from the region's most active volcano, Piton de la Fournaise, on the island of Reunion, in 1640. Réunion has recorded more than 150 eruptions since then.
Réunion was claimed by France around 1662 and has been French virtually continuously since then. French settlers began to move in from 1715, and today, 600,000 people live on the 2,510 km2 island. La Réunion is one of France's overseas departments. Piton de la Fournaise volcano is being monitored by one of the world's leading observatories, established in 1980.
The Comoros islands were controlled by Moslem Sultans until occupied by the French in the latter half of the 19th century. After the early eruption mentioned above (1050 AD ± 150) no further reports are known until the early 19th century. The Comoros became a French overseas territory in 1947 and declared independence in 1975.

Apple purportedly wants 'folded cameras' with periscope lenses in future iPhones
Apple has begun looking for suppliers of "folded cameras" in order to strengthen the optical zoom feature of its iPhones, according to Korea IT News
A folded camera refracts light like a periscope and has lenses and sensors placed horizontally and not vertically. Korea IT News says that Apple plans to introduce triple cameras to its smartphone line. If a smartphone has a such a lens, it can provide a hybrid zoom range of 10X or even higher depending on the tunnel length and lens element arrangement.
Periscope lenses allow for greater optical zoom by bouncing light inside the phone off a mirror before passing it through another smaller lens which can be moved closer and further away from the sensor, amplifying the light even more.
Apple has been granted for periscope lens over the years. For example, in 2015, it was granted a parent for "Mirror Tilt Actuation" (pictured above) for an assembly the includes a folded optics arrangement such that light enters the lens and mirror assembly through a first lens with an optical axis of the first lens orthogonal to the plurality of moveable lens elements.
And last year the US Patent and Trademark Office granted Apple two patents for a periscope camera lens. The first was a "folded lens system with five refractive lenses" and the second patent was for "three refractive lenses."

Business or Brand(Revisd)
Business or Brand
There are some differences between growing a brand and growing a business. If They of course work together, but growing each is a slightly different experience.
A brand can typically exist independently of the businesses that operate under its umbrella. A brand is a broader expression of your business, it's the image or identity behind your business, your ventures, your community. Let's take a closer look at the difference between growing a brand and growing a business.
Sales-focused or community-focused
The goal of your business is likely to generate income, while the broader goal of building a brand should be to grow a community. That community can of course lend to sales - that's how brand and business go hand-in-hand, and why both are so important. However, to grow a brand, you're not focused on the number of products you sell or the number of leads you generate - you're more focused on engagement, reach, and recognition.
While building a business involves expanding products or offerings, building a brand typically means focusing on a single idea or focus that you want your brand to embody. Your brand creates a reputation for you and any businesses that operate under that brand. It's what helps people identify and relate to your business.
Which one is larger?
Because building a brand goes beyond generating income or offering new products, it focuses more on public perception and sentiment. It is not about what you sell, it is about how you make your people feel. For example, bringing in Coca-Cola again, the sugary, carbonated beverage brings thoughts of unexpected moments of happiness, not because of the product itself, necessarily, but because of the branding around the product.
Many of us have likely seen the Coca-Cola commercials showing joyful people sharing a cola, promoting the "share a Coke" campaign. It becomes more than a beverage this way; instead, it's a community for those who love the brand and its products. This is a clear example of how product, business, and brand, work together to create community and sales. It's these kinds of campaigns and connections that stand out in people's minds and create a memorable view of your brand and how your company functions within that brand. It brings your products and offerings together with the connection you need to have with your customers in order to keep them interested in those products and offerings.
Brand can not be taken away
Your business might fail, but a brand doesn't work that way. A brand only fails if you fail to find the right community and continue growing it. If it doesn't work, you can likely just try shifting the direction of your brand or changing the focus. It can't ever be taken away from you or stolen, because it's an expression of your values, views, and goals rather than a physical offering of services or products.
Your business may end for one reason or another, but your brand can easily live beyond that. Brand is the face and voice of any companies that exist as part of it. So in that sense, a brand is more of an idea than a tangible item or entity, and no one can take an idea from you! And in that way, growing a brand becomes just as important in any business venture as growing the company or business itself.
Equally important
As an entrepreneur, it's equally important to grow brand and business. Your business allows you to solve the needs within the community your brand creates, and your brand allows you to reach more people whose needs your business can help to solve. Growing both of them simultaneously helps you to reach your business goals. Sure, these concepts can operate independently, but the most successful companies have dedicated communities and recognition around their brand - so take the time to establish and build your brand with your business.

Acoustic panels and baffles are used to absorb noise and reduce the passage of sound through a building.
Sound absorbing wall panels, ceiling panels and baffles can provide a high quality, effective acoustic solution for a variety of commercial building environments including:
- Schools & Educational Facilities
- Manufacturing & Industrial Warehouse Units
- Conference Facilities
- Community Centres
- Restaurants & Dining Facilities
Acoustic panels and baffles are used to create a comfortable environment in large open spaces. In planning the installation consideration should be given to the type of space that is being separated, the practical implications such as the requirements of those using the it and the activities to be carried out within the area.
Acoustic panels are available in a variety of shapes, sizes and colours or can be printed with a design of choice if required.
What are the benefits of acoustic panels and baffles?
An effective acoustic solution can aid concentration, speech clarity and privacy by reducing sound propagation throughout a building. They are particularly helpful when installed in open-plan areas of a building, changing the dynamic of noise in one area, which might otherwise overpower activities in another area. Effective baffles and sound insulation are also proven to encourage a better understanding and improved behaviour in a school setting.

Optimal Collection of Data for Parameter Identificationby F. E. Udwadia, Univ of Southern California, Los, Angeles, CA, USA,
Document Type: Proceeding Paper
Part of: Dynamic Response of Structures
Abstract: In this paper, the author attempts to study the optimal spacing of measurements for a structural system modelled by a single-degree-of-freedom oscillator so that the variance of one or more of the parameters being identified is minimized. The study starts with a linear oscillator, and using Fourier transforms, derives a set of linear algebraic equations. The condition on the measurement frequencies so that the estimated variance of either the mass parameter, the stiffness parameter or the damping parameter is minimal is derived analytically. It is also found that there may exist a set of frequencies at which no additional information on that parameter is available, yielding no reduction in its estimated variance. The determination of the optimal measurement frequencies depends solely on the nature of the forcing function used in the identification procedure and are invariant with respect to the actual values of the parameters being estimated.

Warm compresses can hasten the resolution of inflammation and infection in the eyelids.
Types of warm compresses
The best way to warm the eyelids is to use a wheat bag eye mask. These provide both heat and moisture as wheat bags must be wet before heating. Wheat also holds its heat for longer than other methods. Dampen the outer covering of the wheat bag and place it in your microve. How long to heat your bag in your microwave will require a little experimentation. You want the wheat warm, not scalding.
There are three other common techniques:
- The simplest method is to fill a bowl with very hot water from the kitchen tap, wet a flannel in this water, wring it out, and place it over the inflamed area. Unfortunately flannels cool quickly. Once again, be careful not to make the flannel too hot
- A thermos can be filled with boiling water. The thermos mouth is placed underneath the eyelid, allowing steam to warm the affected skin. You must be careful not to place your eyelid too close to the thermos mouth
- Finally, you can use a hot wooden spoon. The wooden spoon is heated by placing it in a boiling kettle or pot of water. After a minute or two the spoon is withdrawn and dried carefully on a towel to remove all boiling water. The warm wood is then placed over the eyelid
How long and how often?
Hot compresses should be applied for about 10 minutes, four to six times a day to begin with. After a few day, just one treatment is usually enough.
What to expect
Please note that due to the application of heat the skin around the area will look pink or reddened after treatment. It is important that you don't confuse this with progression of infection or inflammation. An assessment of whether the changes in the lid are getting worse should be made an hour or two after treatment, not immediately following treatment.

McNemar's test to analyze a matched case-control study
McNemar's test is used to compare paired proportions. It can be used to analyze retrospective case-control studies, where each case is matched to a particular control. Or it can be used to analyze experimental studies, where the two treatments are given to matched subjects. Read an example with explanation.
Use McNemar's test (and this calculator) only when you are analyzing matched pairs. Each value you enter above represents a number of PAIRS. The total number of subjects in the study is twice the total of the values you enter above.

Send SCSI READ LONG command to DEVICE. The read buffer is output in hex
and ASCII to stdout or placed in a file. Note that the data returned includes
the logical block data (typically 512 bytes for a disk) plus ECC
information (whose format is proprietary) plus optionally other proprietary
Arguments to long options are mandatory for short options as well.
uses a SCSI READ LONG(16) command. The default action is to use a SCSI
READ LONG(10) command. The READ LONG(10) command has a 32 bit field for
the lba while READ LONG(16) has a 64 bit field.
sets the 'CORRCT' bit in the SCSI READ LONG command. When set the data is
corrected by the ECC before being transferred back to this utility. The
default is to leave the 'CORRCT' bit clear in which case the data is
output the usage message then exit.
where LBA is the logical block address of the sector to read. Assumed
to be in decimal unless prefixed with '0x' (or has a trailing 'h'). Defaults
to lba 0. If the lba is larger than can fit in 32 bits then the --16
option should be used.
instead of outputting ASCII hex to stdout, send it in binary to the
file called OF. If '-' is given for OF then the (binary)
output is sent to stdout. Note that all informative and error output is
sent to stderr.
sets the 'PBLOCK' bit in the SCSI READ LONG command. When set the
physical block (plus ECC data) containing the requested logical block
address is read. The default is to leave the 'PBLOCK' bit clear in
which case the logical block (plus any ECC data) is read.
opens the DEVICE read-only rather than read-write which is the
default. The Linux sg driver needs read-write access for the SCSI
READ LONG command but other access methods may require read-only
increase the level of verbosity, (i.e. debug output).
print the version string and then exit.
where BTL is the byte transfer length (default to 520). If the
given value (or the default) does not match the "long" block size of the
device, the appropriate BTL is deduced from the error response and
printed (to stderr). The idea is that the user will retry this utility
with the correct transfer length.
If a defective block is found and its contents, if any, has been
retrieved then "sg_reassign" could be used to map out the defective
block. Associated with such an action the number of elements in
the "grown" defect list could be monitored (with "sg_reassign --grown")
as the disk could be nearing the end of its useful lifetime.
Various numeric arguments (e.g. LBA) may include multiplicative
suffixes or be given in hexadecimal. See the "NUMERIC ARGUMENTS" section
in the sg3_utils(8) man page.
As a data point, Fujitsu uses a 54 byte ECC (per block) which is capable
of correcting up to a single burst error or 216 bits "on the
fly". [Information obtained from MAV20xxrc product manual.]
The exit status of sg_read_long is 0 when it is successful. Otherwise see
the sg3_utils(8) man page.


Electrical Firing System - Firing Cables
Firing Cables
The type of firing cable used depends primarily on how many conductors is needed. Generally, 16 or 50 conductor cables are used, being this is the most common type of firing system configuration. Some systems are designed with a specific male/female polarity (i.e. one type solely used at firing system end and one type used at field module end) and some use the same sex connector for both ends. The specific polarity design usually used to imply the "direction" of the firing current and/or data signal (computerized system only); however, this is unnecessary in an analog (non-computerized) firing system, where there is not necessarily an "input" and "output" of the field module. In other words, you don't have to worry about which end of the cable goes where in an analog system which uses the same sex connector on both the slave and firing control module, ultimately saving you time during setup. In addition, firing cables can have a separate ground line secured to them for systems which are not internally grounded. See pictures below.

The Politics of Planting
Israeli-Palestinian Competition for Control of Land in the Jerusalem Periphery
Shaul Ephraim Cohen has conducted an unprecedented study of planting in the region and the control of land it signifies. In The Politics of Planting, he provides historical background and examines both the politics behind Israel's afforestation policy its consequences. Focusing on the open land surrounding Jerusalem and four Palestinian villages outside the city, this study offers a new perspective on the conflict over land use in a region where planting has become a political tool.
For the valuable data it presents—collected from field work, previously unpublished documents, and interviews—and the insight it provides into this political struggle, this will be an important book for anyone studying the Israeli-Palestinian conflict.

|This guidance document provides basic information about used oil management practices for used oil collection programs. The rules can be found in Title 128 – Nebraska Hazardous Waste Regulations.
Used Oil Collection
- Definition of used oil: Any oil that has been refined from crude oil or any synthetic oil that has been used, and as a result of such use, is contaminated by physical or chemical impurities. (Title 128, Chapter 1, §140)
- New oil is never considered "used oil."
- Examples of substances that are considered used oil and meet the used oil exemption:
- Spent oil from gasoline and diesel engines
- Spent refrigerant lubricating oil
- Spent lubricating oil from aircraft reciprocating and jet engines
- Spent hydraulic fluid
- Spent heat transfer fluids
- Spent transmission fluid
- Cutting oils
Examples of materials that are not used oil:
Used oil that exhibits one or more characteristics of hazardous waste but is recycled in some manner other than being burned for energy recovery is exempt from hazardous waste regulation (Title 128, Chapters 4, and 7 through 23).
Used oil mixed with a listed hazardous waste is a hazardous waste. In fact, if used oil contains more than 1000 ppm of total halogens it is presumed to be a hazardous waste on the assumption that it has been mixed with a halogenated hazardous waste listed in Title 128, Chapter 3, §013 through 016. This presumption may be rebutted. If a used oil collector accepts "rebutted presumption" used oil, we recommend that documentation be kept.
A used oil generator or collector who gives (or sells) used oil directly to an off-specification used oil marketer is not a marketer of used oil. (See page 3 for a discussion of off-specification used oil.) Obtain documentation. Documentation from the off-specification used oil marketer must indicate what he does with the used oil; that is, he does not burn the used oil for energy recovery himself. This documentation is standard in the used oil industry.
A collector of used oil is subject to the used oil marketer provisions of Title 128, Chapter 7, §010.04 if he provides that used oil directly to a person who burns used oil for energy recovery.
The analysis requirement at Title 128, Chapter 7, §010.04B1 may be skipped if the collector/generator stipulates the oil does not meet specification.
Used oil marketers must notify NDEQ of that activity. This notification is done using State of Nebraska Form 8700-12, "RCRA Subtitle C Site Identification Form" commonly referred to as the "Notification of Hazardous Waste Activity 8700-12 Form."
Used oil marketers must use an invoice system. When the marketer initiates a shipment of off-specification used oil, the marketer must send the receiving facility an invoice that has an invoice number, the marketers NDEQ ID #, the names and addresses of both the sending and receiving facilities, the quantity of the off-specification used oil, the date of shipment, and a statement that says "This used oil is subject to NDEQ regulation under Title 128, Chapter 7". A copy of the invoice must be kept for three years.
The marketer must obtain certain written and signed notices from the used oil burner to document the used oil is burned in a proper device. See Title 128, Chapter 7, §010.04B5.
If the marketer claims the used oil meets specification, the marketer must keep copies of the analysis that proves such for three years, maintain a log with certain required information, and provide a cross reference between the log and the used oil analysis.
A person may market off-specification used oil only to burners or other marketers who have notified NDEQ (or other authorized state/EPA) of used oil activities and who have a NDEQ identification number.
- Spent antifreeze
- Brake fluid
- Solvents of any kind
- Unused motor oil
Burning Used Oil
- Used oil burned for energy recovery is subject to the requirements of Title 128, Chapter 7, §010. This section includes:
- A prohibition against burning used oil mixed with hazardous waste, except under limited circumstances.
- A prohibition against burning off-specification used oil in a used oil fired space heater, except under limited circumstances.
- Requirements for generators of used oil burned for energy recovery.
- Requirements for used oil marketers (see discussion below).
- Requirements for burners of used oil.
Off-specification used oil is used oil that exceeds any one or more of the levels for the following:
Arsenic - 5 ppm
Cadmium - 2 ppm
Chromium - 10 ppm
Lead - 100 ppm
Flash Point - 100° F (minimum)
Total Halogens - 4,000 ppm
Used oil that is a hazardous waste solely because it exhibits a characteristic of hazardous waste may be burned for energy recovery if:
- It is not mixed with hazardous waste. This means the used oil may be a characteristic hazardous waste in its own right, but no additional hazardous waste may be added.
- The used oil contains hazardous waste generated SOLELY by a person subject to the requirements of a conditionally exempt small quantity generator (CESQG) of hazardous waste. A CESQG generates 220 pounds or less of hazardous waste per month.
- This means public utilities may burn used oil in their utility boilers for energy recovery if it is their own used oil or it is collected from: a) "do-it-yourself" (DIY) used oil generators; b) farmers who are CESQGs as well as DIY oil generators; c) other businesses who are CESQGs; and d) other businesses who generate hazardous waste above the CESQG level only if it can be confirmed their used oil has not been mixed with hazardous waste. If businesses that generate hazardous waste as small quantity generators (SQG) or large quantity generators (LQG) place hazardous waste in their used oil, their used oil is no longer regulated as used oil.
Off-specification used oil may be burned in oil-fired space heaters if the heater burns only used oil that the owner or operator generates, or used oil from do-it-yourself oil changers who generate the used oil as household waste. For example, a state agency that does oil changes can bring their own off-specification used oil to another of their facilities that has a used oil-fired space heater. That same agency cannot take that used oil to be burned in another state agency's used oil-fired space heater. Any of the above can burn do-it-yourself used oil, but be prepared to prove the do-it-yourself oil is what it claims to be. See below for transportation related issues.
Nebraska does not have any quantity limitations on used oil collection or transportation. A hazardous waste manifest is not required for transporting used oil in Nebraska. Transporters must comply with any appropriate Department of Transportation regulations. See the 49 CFR series. Collectors must comply with applicable State Fire Marshall requirements for storage of flammable and combustible materials.
HANDLING USED OIL AND HAZARDOUS MATERIALS
Storage and Collection
- Keep hazardous materials separate, properly labeled, and sealed in the recommended containers.
- Develop a system for monitoring incoming used oil. Locked collection ports can help prevent unwanted materials in your used oil.
- We recommend collection tanks have a clearly visible gage that shows the level of product in the tank and overfill protection. Continued overfilling of used oil collection tanks has occurred when there was no indication the tank was actually full.
- Containers and aboveground tanks used to store used oil shall be in good condition (no severe rusting, apparent structural defects or deterioration (T128, Ch7, §009.04A1); and not leaking (with no signs of visible leaks) (T128, Ch7, §009.04A2)
- Containers and aboveground tanks (and other receptacles of used oil) with a volume of 25 gallons or greater, shall be labeled or marked clearly with the words "Used Oil", T128, Ch7, §009.04A3
- The Department recommends that storage or collection areas be covered. The storage or collection location may need to be fenced and locked if vandalism could be a problem.
- Cap, label, cover, and properly store above-ground outdoor liquid containers and small tanks within a bermed area and on a paved impermeable surface, if possible. This practice helps to prevent spills from running into surface or ground water.
- If possible, store materials under a roof or tarpaulin to protect them from the elements and to prevent contaminated runoff.
- Sweep regularly.
- Inspect hazardous materials storage or collection areas at least weekly to ensure there are no leaks or spills.
- Inspect equipment such as pumps, pipes, storage tanks, valves, and material handling equipment for signs of corrosion, support or foundation failure, or other deterioration.
- Promptly clean up spilled materials to prevent runoff, tracking, and spoilage of other materials.
- Stock cleaning and spill response materials where they are readily available.
- Post reminders of good housekeeping practices.
- Provide instruction on securing containers.
- Schedule housekeeping duties and inspections to ensure good housekeeping is being accomplished.
- Maintain adequate aisle space between containers to facilitate material transfer, easy access to materials, and inspections.
- Close used oil containers between filling or emptying events.
- Store containers, drums, and bags away from direct traffic routes to prevent accidental damage or spills.
- Organize materials neatly for storage.
- Store incompatible materials separately.
- Stack containers according to manufacturer's instructions to avoid damage to containers from improper weight distribution.
- Store containers on pallets or in containment devices
