Wio Terminal Continuous Motion Recognition
In this tutorial, you'll use machine learning to build a gesture recognition system that runs on Wio Terminal. This is a hard task to solve using rule based programming, as people don't perform gestures in the exact same way every time. But machine learning can handle these variations with ease. You'll learn how to collect high-frequency data from real sensors, use signal processing to clean up data, build a neural network classifier, and how to deploy your model back to a device. At the end of this tutorial you'll have a firm understanding of applying machine learning in embedded devices using Edge Impulse.
There is also a video version of this tutorial:
1. Prerequisites
For this tutorial you'll need a supported device. Follow Wio Terminal Edge Impulse tutorial fist before the followings.
Apart from Wio Terminal, here are other supported devices.
If your device is connected under Devices in the studio you can proceed:
Edge Impulse can ingest data from any device - including embedded devices that you already have in production. See the documentation for the Ingestion service for more information.
2. Collecting your first data
With your device connected we can collect some data. In the studio go to the Data acquisition tab. This is the place where all your raw data is stored, and - if your device is connected to the remote management API - where you can start sampling new data.
Under Record new data, select your device, set the label to idle, the sample length to 5000, the sensor to Built-in accelerometer and the frequency to 62.5Hz. This indicates that you want to record data for 10 seconds, and label the recorded data as idle. You can later edit these labels if needed.
There is also another options for External multichannel gas, this uses the Grove - Multichannel Gas Sensor v2 for collecting gas sensor values.
After you click Start sampling move your device up and down in a continuous motion. In about twelve seconds the device should complete sampling and upload the file back to Edge Impulse. You see a new line appear under 'Collected data' in the studio. When you click it you now see the raw data graphed out. As the accelerometer on the development board has three axes you'll notice three different lines, one for each axis.
It's important to do continuous movements as we'll later slice up the data in smaller windows.
Machine learning works best with lots of data, so a single sample won't cut it. Now is the time to start building your own dataset. For example, use the following three classes, and record around 3 minutes of data per class:
 - Idle - just sitting on your desk while you're working.
 - Wave - waving the device from left to right.
 - Circle - drawing circles.
Make sure to perform variations on the motions. E.g. do both slow and fast movements and vary the orientation of the board. You'll never know how your user will use the device. It's best to collect samples of ~10 seconds each.
3. Designing an impulse
With the training set in place you can design an impulse. An impulse takes the raw data, slices it up in smaller windows, uses signal processing blocks to extract features, and then uses a learning block to classify new data. Signal processing blocks always return the same values for the same input and are used to make raw data easier to process, while learning blocks learn from past experiences.
For this tutorial we'll use the 'Spectral analysis' signal processing block. This block applies a filter, performs spectral analysis on the signal, and extracts frequency and spectral power data. Then we'll use a 'Neural Network' learning block, that takes these spectral features and learns to distinguish between the three (idle, circle, wave) classes.
In the studio go to Create impulse, set the window size to 2000 (you can click on the 2000 ms. text to enter an exact value), the window increase to 80, and add the 'Spectral Analysis' and 'Neural Network (Keras)' blocks. Then click Save impulse.
Configuring the spectral analysis block
To configure your signal processing block, click Spectral features in the menu on the left. This will show you the raw data on top of the screen (you can select other files via the drop down menu), and the results of the signal processing through graphs on the right. For the spectral features block you'll see the following graphs:
 - After filter - the signal after applying a low-pass filter. This will remove noise.
 - Frequency domain - the frequency at which signal is repeating (e.g. making one wave movement per second will show a peak at 1 Hz).
 - Spectral power - the amount of power that went into the signal at each frequency.
A good signal processing block will yield similar results for similar data. If you move the sliding window (on the raw data graph) around, the graphs should remain similar. Also, when you switch to another file with the same label, you should see similar graphs, even if the orientation of the device was different.
Once you're happy with the result, click Save parameters. This will send you to the 'Feature generation' screen. In here you'll:
 1. Split all raw data up in windows (based on the window size and the window increase).
 2. Apply the spectral features block on all these windows.
Click Generate features to start the process.
Afterwards the 'Feature explorer' will load. This is a plot of all the extracted features against all the generated windows. You can use this graph to compare your complete data set. E.g. by plotting the height of the first peak on the X-axis against the spectral power between 0.5 Hz and 1 Hz on the Y-axis. A good rule of thumb is that if you can visually separate the data on a number of axes, then the machine learning model will be able to do so as well.
Configuring the neural network
With all data processed it's time to start training a neural network. Neural networks are a set of algorithms, modeled loosely after the human brain, that are designed to recognize patterns. The network that we're training here will take the signal processing data as an input, and try to map this to one of the three classes.
So how does a neural network know what to predict? A neural network consists of layers of neurons, all interconnected, and each connection has a weight. One such neuron in the input layer would be the height of the first peak of the X-axis (from the signal processing block); and one such neuron in the output layer would be wave (one the classes). When defining the neural network all these connections are intialized randomly, and thus the neural network will make random predictions. During training we then take all the raw data, ask the network to make a prediction, and then make tiny alterations to the weights depending on the outcome (this is why labeling raw data is important).
This way, after a lot of iterations, the neural network learns; and will eventually become much better at predicting new data. Let's try this out by clicking on NN Classifier in the menu.
Set 'Number of training cycles' to 1.. This will limit training to a single iteration. And then click Start training.
Now change 'Number of training cycles' to 2 and you'll see performance go up. Finally, change 'Number of training cycles' to 100 or more and let training finish. You've just trained your first neural network!
You might end up with a 100% accuracy after training for 100 training cycles. This is not necessarily a good thing, as it might be a sign that the neural network is too tuned for the specific test set and might perform poorly on new data (overfitting). The best way to reduce this is by adding more data or reducing the learning rate.
4. Classifying new data
From the statistics in the previous step we know that the model works against our training data, but how well would the network perform on new data? Click on Live classification in the menu to find out. Your device should (just like in step 2) show as online under 'Classify new data'. Set the 'Sample length' to 5000 (5 seconds), click Start sampling and start doing movements. Afterwards you'll get a full report on what the network thought that you did.
If the network performed great, fantastic! But what if it performed poorly? There could be a variety of reasons, but the most common ones are:
 1. There is not enough data. Neural networks need to learn patterns in data sets, and the more data the better.
 2. The data does not look like other data the network has seen before. This is common when someone uses the device in a way that you didn't add to the test set. You can add the current file to the test set by clicking ⋮, then selecting Move to training set. Make sure to update the label under 'Data acquisition' before training.
 3. The model has not been trained enough. Up the number of epochs to 200 and see if performance increases (the classified file is stored, and you can load it through 'Classify existing validation sample').
 4. The model is overfitting and thus performs poorly on new data. Try reducing the learning rate or add more data.
 5. The neural network architecture is not a great fit for your data. Play with the number of layers and neurons and see if performance improves.
As you see there is still a lot of trial and error when building neural networks, but we hope the visualizations help a lot. You can also run the network against the complete validation set through '

|What Is the Purpose of the Kabbalah Red String?|
Followers of the mystical Judaic tradition Kabbalah often believe that wearing a red string tied around the left wrist will ward off the evil eye. According to Kabbalah teachings, the talisman works as a "spiritual vaccination": the red string, being the color of danger, will shield the wearer against danger and negativity. Before Kabbalah red string is sold to followers, it is wound around the tomb of Rachel, a Biblical matriarch whose motherly protection becomes part of the red string's power.
Many cultures have used a red string, ribbon, or cloth as a ritualistic talisman of protection, including the ancient Greeks, Egyptians and Chinese; red string also appears in the folk customs of Ireland, Romania and India. Scholar Elly Teman identifies three elements that make the red string such a powerful cross-cultural symbol: the knotting of the thread, symbolizing binding and closure; the circularity of the string, symbolizing sacredness and protection; and the string's redness, connoting blood, earth and courage.
The Kabbalah red string is a type of "segulah," the Jewish term for a protective, healing spiritual act. However, Rabbi Ahron Lopiansky claims that there is no scriptural basis for this particular segulah, citing instead a Talmudic verse that equates the red-string ritual to superstition and idol worship.
The modern red string ritual began in the '30s when those with fertility problems began making pilgrimages to Rachel's Tomb; thus, early on, the red string was used primarily as a fertility charm. This tradition disappeared while the tomb was under Jordanian rule, but reappeared after the Six Day War in 1967, and the string came to mean protection rather than fertility. The Kabbalah string must be wound seven times around Rachel's Tomb to endow it with full protective powers.
In the '80s, the red string became more and more popular as the conditions in Israel grew more and more uncertain; Elly Teman believes that national anxiety is at the root of contemporary usage of the Kabbalah string. Then, in the late '90s, many celebrities (including Madonna, David Beckham and Britney Spears) began wearing a red string as a fad accessory.

The ONCORELIEF vision is realized through a multiand trans-disciplinary user-centric approach with concrete technical and scientific objectives and builds upon the following five pillars:
Analysis of clinical settings, treatment parameters and environment dynamics and driving forces of cancer patient wellbeing
ONCORELIEF will adopt a user-centred approach (see also Pillar 5), placing the patient at the centre of the posttreatment ecosystem and analysing the parameters that affect his/her wellbeing and health status within the everyday environment (i.e. personal, social, working, etc.), resulting to the effective design of the ONCORELIEF solution. This pillar consists of the following objectives:
- Objective 1.1: To thoroughly analyse clinical settings at diagnosis, treatment and after-treatment level in conjunction with environmental parameters affecting the health status, the QoL and WB of a cancer patient focusing on the parameters of both external and personal space affecting the long-term effects of cancer treatment.
- Objective 1.2: To analyse oncology-related socio-cultural and psychological factors of personal WB and QoL focusing on the patient's everyday routine and their needs, during and after treatment.
- Objective 1.3: To record and analyse the needs of cancer-patients regarding their everyday life and activities, perceived WB, environment and after-cure improvement shortand mid-term.
- Objective 1.4: To incorporate health law and GDPR aspects in user requirements in order for the solution developed to be both ethically and legally compliant.
- Objective 1.5: To define the technology interventions positively impacting the everyday life of a cancer patient through which the project scenarios of use will be defined.
Exploiting Big Data and AI capabilities for holistic post-treatment insights generation
Amongst the cornerstones of ONCORELIEF is the employment of novel big data and AI techniques to analyse patterns and generate insights that will help to better understand and consequently transform services and knowledge that needs to be conveyed to users, which has to do with their post-treatment QoL and way of living. This pillar consists of the following objectives:
- Objective 2.1: To identify, collect and transform various heterogenous data streams into a well specified, extendable, linkable and standard-compliant data model able to describe critical factors relevant to post treatment environments and activities.
- Objective 2.2: To employ novel GDPR perspective security and privacy mechanism for enabling the secure exchange of data and the generation of trust to the ONCORELIEF platform, safeguarding private sensitive data of users
- Objective 2.3: To design a set of smart algorithms that can be used at generic levels for generating reports that provide group analytics for monitoring similar individuals and that verify or possibly lead to new clinical protocols.
- Objective 2.4: To individualize data algorithms though AI outputs for offering personalized insights and recommendations to individuals based on their specific medical history, needs, life patterns, environment and activities.
- Objective 2.5: To incorporate AI elements for the development of self-learning and incorporation of empathic features to the assistant providing it with the necessary intelligence and the empathic personalized behavioural features related with the patient characteristics, cancer type, treatment, clinical settings, etc.
Development of innovative technological elements for providing personalized wellbeing
Building upon the active user-involvement, ONCORELIEF will proceed with the development of its technological concepts, including the implementation of a novel smartphone application (ONCORELIEF Guardian Angel) and wellbeing QoL index (ONCORELIEF index) used as the basic tool for supporting the patients, and the development of a platform incorporating AI elements and advanced data processing for accurate wellbeing assessment, while integrating with low-cost, off-the-shelf sensing devices for measuring parameters of the everyday environment (i.e. personal, social, working, etc.). This pillar consists of the following objectives:
- Objective 3.1: To create a digital smart guardian angel running on a smartphone, providing personalized information on cancer-patients wellbeing and supporting them in everyday routine tasks that improve their aftertreatment quality of life and decrease their psychological stress.
- Objective 3.2: To setup a sensing infrastructure incorporating off-the-shelf sensing devices, measuring environment parameters affecting the wellbeing of the cancer-patient. In order to assess the wellbeing and status of the user, a combination of wearable sensing devices, which provide very accurate readings about the user activities and bio-signals such as heart rate or oxygen blood level, and other ambient non-wearable monitoring devices, that can greatly improve the contextual information of the user, will be used.
- Objective 3.3: To define an Index reflecting the wellbeing level of a cancer-patient taking into account (a) the clinical setting of diagnosis, treatment and after-treatment follow-up of the patient, (b) measurable parameters and inputs provided by the patient, and (c) dynamically adjusting to the treatment and after-cure changes by reflecting the overall wellbeing level of the users.
- Objective 3.4: To develop reporting tools giving useful insights and notifications to the patient regarding his wellbeing, health status, psychological wellbeing and post-treatment related needs, and on the progress regarding its condition and its measurable parameters.
Piloting in different cancer types and patient-environment settings
ONCORELIEF will be exhaustively validated and evaluated in real-life settings, for different types of cancer, taking into account cross-gender needs and diverse patient environments. Two 12-month pilot studies (Germany and Italy) are planned, with the participation of 450 patients. Additionally, pre-pilot activities will take place, focusing on ONCORELIEF technical verifications and for collecting early user feedback and incorporating it into the ONCORELIEF prototypes.
- Objective 4.1: To validate early prototypes of the proposed system and services for trial operation in semicontrolled environments aiming to use data collected to improve the technical aspects (robustness, interfaces, resources usage, etc.) of the system for the trials execution with end users.
- Objective 4.2: To validate the proposed solution for 12 months with active cancer patients following posttreatment suffering from different types of cancer, namely Acute Myeloid Leukaemia (AML) and Colorectal Cancer (CRC), in various pilot sites. This will allow the consortium to examine the projects' impact.
- Objective 4.3: Perform controlled pre-pilot activities on the specifications and projects' early prototypes with clearly envisioned outcomes at Year 1 and Year 2 of the project that will be put under the evaluation and scrutiny of the end-users. This will help to focus on the real value delivered to end users by incorporating their feedback at critical progress milestones as well as train our data-models, thereby improving their accuracy and performance.
Active engagement of stakeholders resulting to measurable impacts
ONCORELIEF will involve the stakeholders during the whole project duration to achieve high-user acceptance, by adopting a user-centred design methodology (through the use of design thinking methods and tools) and thoroughly designing our pilots. This principle will be combined with rich dissemination activities and detailed feasibility and competition analysis for the development of an accurate go-to-market strategy. Towards this direction the following objectives will be fulfilled:
- Objective 5.1: Engage the stakeholders by adopting a design thinking methodology including six stages of involvement: define, research, ideate, prototype, deliver and learn, helping to understand better the user needs and pains, encourage inputs from a wide variety of stakeholders (patients, doctors, healthcare professionals, etc.), and design solutions that best reflect the preferences and user requirements.
- Objective 5.2: Involve stakeholders from multiple disciplines Following the previous one, this objective regards the engagement and participation in the pilots and evaluation process of a sufficient number of different types of stakeholders (e.g. patients, doctors, healthcare professionals, and psychologists etc.).
- Objective 5.3 Achieve wider user-driven steering of the project by establishing synergies with European and international associations and currently running EU R&I projects that will in turn promote and facilitate the smooth and early adoption of the proposed offerings.
- Objective 5.4: Define appropriate business and go-to market strategy in order to enable the wide, smooth and fast adoption of its outcomes by relevant stakeholders.

Wings held high, the Panther appeared ready to take flight like a bird flapping its wings. The wings folded to maximize space aboard aircraft carriers in the early 1950s, and were usually positioned nearly vertical. On this day, the staff was testing special wing struts they had fabricated from an original piece. Numerous patches were visible on the airplane where holes and dents had been filled with an aluminum epoxy compound, then sanded.

Belt Conveyor for Maximum Customer Satisfuction
The belt conveyor plays a special role in Hawkplant conveyor technology portfolio. On the one hand, it belongs to the family of continuous conveyors, but in our case, it is limited to the transport of general cargo and individual load carriers within a stationary conveyor system. The Hawkplant belt conveyor is specially designed according to customer requirements and uses a long-proven modular construction kit that is optimized and adapted to the respective application. This allows maximum flexibility and increases space utilization in a wide range of production environments. The belt conveyor system works with maximum efficiency in terms of both material flow and energy requirements, making it a profitable and environmentally friendly investment in the future.
The Very Low Maintenance and Minimized Susceptibility To Interference And Wear Characterize The Hawkplant Belt Conveyor
The tried-and-tested Hawkplant philosophy serves to speed up individual work processes and to sustainably reduce production costs in your company. The belt conveyor has been part of the Hawkplant system family for many years and has established itself as a fixed size in the transport of cargo 500 to 1000 mm to 40 meters. In addition to horizontal transport, the belt conveyor can also be used in the form of a continuous elevator over a downhill slope. The conveyed enters a higher level without a freight elevator or the like to install.
In this application, a special conveyor belt is used, which provides a firm grip and ensures that even heavier goods reach their destination. The seemingly effortless and very low-noise conveyor belt brings various production units in the form of boxes, boxes, boxes, tires, rims, barrels and various other containers and many more, fast, accurate and uncomplicated to their destination. In order to meet the requirement of separation from a conveyor line into different areas or the merging of one or more conveyor lines, simple as well as equally effective side guides are available. An additional option is provided by the pneumatically controlled pushers. The belt conveyor is designed for uninterrupted operation, delivering maximum productivity coupled with high.

What is the difference between putting $DB::single=1 and $DB::single=2 in your code? Both seem to have the identical effect of halting execution at the statement following the assignment when I do a 'c' on the perl debugger command line.
perldebug says that a value of 1 is equivalent to having just pressed's' to get to the next statement, and 2 is the same as 'n', but what difference does it make how you got to the statement?

From perldebug:
If you set $DB::single to 2, it's equivalent to having just typed the n command (which executes over subroutine calls), whereas a value of 1 means the s command (which enters subroutine calls).
That much you know already.
From a user point of view, I'm pretty sure there is no difference. I base this on an examination of the actual DB.pm source code.
Let's follow this logically. You may want to refer to the source code. I've simplified some of the code to remove unnecessary detail but you should be able to get the idea from my descriptions.
When you are executing code in the debugger, there are (at least) two important variables, running and single. The combination of these is what decides whether code is run:
running single description
 0 ? not running
 1 0 running flat-out
 1 1 single stepping, execute into function
 1 2 single stepping, execute over function
The DB() function is executed for every single line, and it contains the following snippet which will stop the running if single has been set (it always executes the current line regardless):
if ($DB::single) {
 $DB::single = 0;
 $running = 0;
That's why, if you set the variable in your Perl code, it will break (by break, I mean "stop running the code", not "damage somehow") the debugger at the next line.
When running is 0, the DB() function enters this little loop:
# Now sit in an event loop until something sets $running
do {
 $c->idle; # call client event loop; must not block
} until $running;
In other words, it waits on a user command which sets running back to 1. This can be done by one of the following three functions:
sub next {
 $DB::single = 2;
 $running = 1;
sub step {
 $DB::single = 1;
 $running = 1;
sub cont {
 $DB::single = 0;
 $running = 1;
You can see that these three commands set up a different combination of single and running which will be used while executing the next Perl line (see the earlier table to see what these combinations mean).
The ability to use either 1 or 2 in your Perl code is a direct result of the fact that you're using a sneaky but clever trick to break execution from your Perl code itself, by setting a variable that would normally be set by a debugger command.
That's why it's not the value that matters so much as the fact you're forcing the debugger into a particular state.

not sneaky, well documented. – ysth Dec 20 '10 at 21:54
It may be well documented now but I'm of the opinion that it was a simple side effect of the way DB.pm worked, that someone discovered was useful (even if that someone was the original author). No-one in their right mind would design an API like this :-) They would have provided a function to do it so as to not expose the inner workings, not just let a variable be set to two different values, the difference between those values being absolutely nothing in terms of the use. – paxdiablo Dec 20 '10 at 23:23

ANTH 231: Native North American Cultures: Books
Anthologies vs. Monographs
Edited anthologies are book-length texts that include a set of essays or articles by a variety of authors. Monographs are a book-length text (not a collection of essays or articles). You can't always tell from the record in the catalog whether a book is an edited volume or not--you may need to actually look at the physical book or go into the ebook to figure it out. If a book is written by one or two authors, it is considered a monograph. If the book contains chapters or essays by a bunch of different authors, that is an anthology.

Chinese Flagship Program 中文领航
Photograph: Allie Surina
Student Profile--Allie Surina
1. What is your degree and major?
Bachelor of Arts: Mathematics/Economics double major
2. Why did you choose to study Chinese?
I chose to learn Chinese so that I can work directly with Chinese researchers to study economic development in China's urban centers.
3. What specifically led you to choose the Flagship Program?
I chose the Flagship Program because the instruction pace and content are suited for people who need to use the language in the working world, rather than for people who want to learn about the culture as an end goal. Additionally, the program coordinators are embedding my language learning within my personal career framework so that every Flagship-related opportunity moves me closer to my larger goals.
4. What are the most rewarding things about flagship?
The most rewarding things about Flagship are marking progress through each language level, and building a core group of friendships through the intensive classroom atmosphere.
5. How has your Flagship Program set you apart from other students? What advantages has the program given you?
When professors and other students hear about the goals and details of the Flagship Program, they usually are surprised that such a forward-thinking program exists, and that there are students willing to sign up for the challenge. I have earned a lot of respect from professors who think that Chinese is mostly "unlearnable" for Americans. Through the Flagship Program I have traveled to China twice and am able to network with Chinese people in my own community at home. Between some cultures there are old walls that are difficult to cross. With China and the United States, the culture, history and language of China is that wall. Learning Chinese has given me an opportunity to understand and learn from a culture that was previously a mystery to myself, and my community.
6. How has The Language Flagship helped you to discover your role in the world?
Representing the Language Flagship has given me an opportunity to serve as a culture-translator between the United States and China. I find that people at my school and in my community often ask me questions about the future of China and how things are on the ground there. I enjoy helping people to understand the Chinese point of view in the context of American culture, and I now hope to serve the United States government in some capacity with my research.
7. What are your career goals?
I plan to go to graduate school to study development, governance and public choice. I hope to be a professor in a research university with strong ties to Asian economic development, and would like to work in conjunction with agencies such as the World Bank or the Brookings Institution.

Gothic: From Ghost Town to Field Station
The excitement began in May 1879 when brothers John and David Jennings discovered a rich silver lode at nearby Sylvanite Basin. Hundreds of eager prospectors rushed to the area, seeking their own quick riches. By August 'Gothic City' was officially organized. Along its streets quickly appeared numerous log and frame residences, two hotels, three restaurants, several saloons, two general stores, a school, law and medical offices, a bank, two saw mills, other merchants' buildings, and a post office. Yet, as revealed in Gothic's newspaper, The Gothic Miner, the feverish venture effectively lasted for little more than two years because it became evident that too few diggings yielded ore rich enough for processing. Gothic became such a well-known boisterous mining town that in 1880 Ex-President Ulysses S. Grant came for a personal visit.
Gothic's decline started in the summer of 1881 and, although the town government lived on for a time, it was virtually abandoned by 1890. From then until 1928 few people remained. The notable exception was the colorful Garwood Hall Judd --'The Man Who Stayed'-- who until his death in 1930 was the wily self-appointed Gothic caretaker. Seeing chance for Gothic's revival, Judd played a key role in aiding Dr. John C. Johnson, RMBL founder, in obtaining personal title to part of the abandoned townsite.
Dr. Johnson, then Professor of Biology and Dean at Western State College (WSC) in Gunnison, first saw Gothic in July 1919. From then through 1927 he regularly took college biology students on overnight field trips to Gothic. During those years he became convinced not only that a high-altitude field station was needed, but also that Gothic, with its abundant diverse biota and spectacular location, would be the ideal site.
Since Colorado's political climate at the time barred WSC from providing support, Dr. Johnson went ahead on his own. By 1928 he had persuaded Dr. A. O. Weese and Dr. Aute Richards of the University of Oklahoma, and Dr. L. A. Adams of the University of Illinois, to join him and his wife, Vera, in forming RMBL, an independent Colorado Corporation. He assumed all initial financial responsibility and turned over his Gothic properties to the promising new institution that later acquired additional land. RMBL's first session began in June 1928.
The dilapidated Gothic Hotel and several other ancient buildings remaining from the silver-mining days were repaired and used in RMBL's earliest years until new residences, classrooms, laboratories, and service buildings could be constructed. Three buildings from the 1880s, including the old Gothic Town Hall (now the Gothic Store), and two from about 1910, have been preserved.
During the following years Dr. Johnson, Director of RMBL for its first thirty years, built its instructional and research programs while improving its physical facilities. Students and prominent biologists from all over the United States and other countries come to Gothic to study and gather research data concerning the biota within the area's unique ecosystems.

Showcase of Amazing Paper Made Artworks and Sculptures
Paper is a medium that most of us only use for jotting down our ideas and writing down notes, and think that there is no other use of paper except writing. However, some imaginative artists out there have created spectacular pieces of artwork out of paper. They refer to it as Paper Craft or Paper Artwork.
We have already published a post about Awesome Works of Art Made From Paper and that was greatly appreciated by our readers. Now we have gathered another great collection of Amazing Paper Made Artworks and Sculptures.

Hammerhead sharks are a species of shark found in tropical oceans worldwide. Their name is derived from the unusual shape of their head which gives them increased sensory ability to detect prey.
In the early 18th century, hammerhead sharks were hunted by various individuals, such as the pirates Edward Kenway and Adéwalé. The bones they collected from the sharks were profitable in this era of the West Indies, and Edward used them as crafting material for his second ammunition pouch and his shark hunter outfit.
During the Peloponnesian War, a heavy hammer that was inspired by and dedicated to the hammerhead sharks was made available to the Spartan misthios Kassandra through an Animus modification by Layla Hassan, an Assassin who relieved her memories.
Behind the scenes
In Assassin's Creed IV: Black Flag, hammerhead sharks can be hunted for "hammerhead shark bones". In reality, sharks do not have mineralized bones, only cartilage and connective tissue. These "hammerhead shark bones" are required materials for crafting two items: the pistol ammo pouch II and the shark hunter outfit. Two are needed for the pouch while one bone and one pelt of bull shark skin is needed for the outfit.

Centralised sampling system
The Centralised Sampling System facilitates sample taking from beer tanks. It is a modular system equipped for taking out samples from up to 12 tanks. Because of the position of the sampling valve on vertical fermenters or bright beer tanks, access to sampling point often requires platforms. The system allows for placing the sample valve at the optimal point for sampling: on the middle of the cylindrical part of the vessel, independent of whether there is easy access to this point or not.
When taking a sample there are two possibilities; either sterile or non-sterile sampling. For sterile sampling of the chosen tank, the "sterile" button is pressed and the pipeline to the sampling panel will be steam sterilised. After sterilising, the pipeline is blown dry with sterile air or CO2. Now the "sampling" button can be pressed and the sample media will flow from the chosen tank to the sample coil at the sample panel. By pressing the "flush" button, the pipeline is hereafter flushed with water, steamed and blown dry.
When choosing non-sterile sampling for non-microbiological samples the first step after choosing the tank, is to press the "sampling" button. The sampling process will then be the same as above but without the sterilisation before the sample is taken. The sample valves and pipelines with other valves are CIP'ed together with the tank. The cleaning process is started by pressing the "CIP" button or by external signal from a PLC and runs automatically according to the pre-selected time.
- Fully automatic and safe sampling from selected tanks
- "Fool proof" operation
- Highly sanitary sampling
- Economic solution compared to "cat-walk" installations
- Optimal sampling point position on tank regardless of tank construction and access
- Simultaneous sampling and or CIP

I'm starting to make a symbol and subject index with the package multind. In the symbol index, I would like to group the symbols by thematics, e.g., write set theory notation and have all the symbols below the description, after write operators and have all the notation for the operators, etc.
Does anyone knows how to do this?
I would like to obtain something like the following
Can anyone help me with a minimal working example? Preferably changing the section with page number.

 The package multind is very old and unmaintained. I suggest you to use either imakeidx or splitidx to generate multiple indexes. – karlkoeller Nov 20 '13 at 6:01

 This seems more a work for the glossaries package. – egreg Nov 20 '13 at 8:49
You can use glossaries to do this. I assume you either want to sort your symbols according to definition or to usage since symbols are difficult to sort alphabetically (and your sample isn't alphabetically sorted). With glossaries you can use the package option sort=def to sort in order of definition or sort=use to sort according to usage. In the example below, I've used sort=def (change \setglossarystyle to \glossarystyle if you are using a version of glossaries prior to version 4.0):
% (Pre glossaries v4.0 requires \glossarystyle rather than
% \setglossarystyle)
% Define a command to define operators
% Syntax: \newoperator[options]{label}{operator symbol}
% Similarly for constants
% Define operators
% Define constants
\chapter{Sample Chapter}
Some sample usage of constants:
 \gls{pdash}, \gls{Mcn}, \gls{jnu}
Some sample usage of operators:
 \gls{Mop}, \gls{Aalpha}, \gls{nablaOmega}
More sample usage:
\gls{T}, \gls{I2}, \gls{Jz}, \gls{Gz},
\gls{Mcn}, \gls{Dpq}, \gls{jnu}
In order to build the PDF you need to do:
 1. Run pdflatex
 2. Run makeglossaries
 3. Run pdflatex
The above example produces:
Page 1:
Image of page 1
Page 2:
Image of page 2
Page 3:
Image of page 3
In your example image, you have some lines with multiple entries (for example, c, c_1, c_2, \ldots, v_n). There are various ways to deal with these. You could designate the first in the list (e.g, c) as the main parent entry, and the remainder as sub-entries, and then define a glossary style that puts the sub-entry names after the parent entry name, but this will complicate the location list. However, I think the easiest solution is probably to define an entry with the specified list and then use \glsdisp or \glslink whenever you use it.
For example:
\newconstant{c}{c, c_1, c_2, \ldots, v_n}
Then in the document:
In-line: $\glslink{c}{c}$ or $\glslink{c}{c_1}$ or $\glslink{c}{c_2}$ etc.

Experimental Validation of an Elastic Registration Algorithm for Ultrasound Images
MetadataShow full item record
Ultrasound is a favorable tool for intra-operative surgical guidance due to its fast imaging speed and non-invasive nature. However, deformations of the anatomy caused by breathing, heartbeat, and movement of the patient make it difficult to track the location of anatomical landmarks during intra-operative ultrasound-guided interventions. While elastic registration can be used to compensate for image misalignment, its adaptation for clinical use has only been gradual due to the lack of standardized guidelines to quantify the performance of different registration techniques. Evaluation of elastic registration algorithms is a difficult task since the point to point correspondence between images is usually unknown. This poses a major challenge in the validation of non-rigid registration techniques for performance comparisons. Current validation guidelines for non-rigid registration algorithms exist for the comparison of techniques for magnetic resonance images of the brain. These frameworks provide users with standardized brain datasets and performance measures based on brain region alignment, intensity differences between images, and inverse consistency of transformations. These metrics may not all be suitable for ultrasound registration algorithms due to the different properties of the imaging modalities. Furthermore, other metrics are required for validating the registration performance on different anatomical images with large deformations such as the liver. This work presents a validation framework dedicated for ultrasound elastic registration algorithms. Quantitative validation metrics are evaluated for ultrasound images. These include a simulation technique to measure registration accuracy, a segmentation algorithm to extract anatomical landmarks to measure feature overlap, and a technique to measure the alignment of images using similarity metrics. An extensive study of an ultrasound temporal registration algorithm is conducted using the proposed validation framework. Experiments are performed on a large database of 2D and 3D US images of the carotid artery and the liver to assess the performance of this algorithm. In addition, two graphical user interfaces which integrate the image registration and segmentation techniques have been developed to visualize the performance of these algorithms on ultrasound images captured in real time. In the future, these interfaces may be used to enhance ultrasound examination.

Background. Using in-depth qualitative methods, we investigated negative contraception counseling experiences, including those felt to be coercive or discriminatory, in a population of postpartum urban minority women. Methods. Brief surveys and semi-structured interviews were conducted with 30 consenting postpartum women who had received care at a Medicaid-funded obstetrics clinic. In-person one-on-one interviews were then reviewed for themes using an iterative process of qualitative analysis. Results. In this sample of African American (63%) and Hispanic (37%) women (median age 26), 73% had unplanned pregnancies. Features of negative counseling experiences included having insufficient, non-physician-directed and impersonal counseling. Most women had experienced episodes of poor communication with providers; 10 described feeling coerced or perceiving racially-based discrimination in counseling. Conclusions. Negative experiences with contraceptive counseling may affect contraception utilization. Contraceptive education should respect each individual's autonomy, culture, and values.

WEDNESDAY, Oct. 29 (HealthDay News) -- Breast-fed children are less likely to experience behavioral or mental health issues than those who are not breast-fed, according to research presented this week at the American Public Health Association meeting in San Diego.
Katherine Hobbs Knutson, M.D., of Massachusetts General Hospital in Boston and a colleague examined 102,353 parent/ guardian interviews concerning the health of children aged 10 months to 18 years from the 2003 National Survey of Children's Health. Parents were asked questions regarding breast-feeding and their children's behavior, and answers were analyzed via multivariate regression.
Parents/guardians of breast-fed children were significantly less likely (23 percent) to report apprehension over their children's ability to learn for themselves. Similarly, they were significantly less likely (24 percent) to report concern over learning in preschool. Odds of concern regarding the children's behavior, medically diagnosed behavioral/conduct problems and receipt of mental health care were decreased by 15 percent, 37 percent and 37 percent, respectively, in parents/guardians of breast-fed children compared with those of non-breast-fed children.
The authors conclude, "These findings support current evidence that breast feeding enhances childhood intellectual ability while providing new evidence that breast feeding may contribute to childhood emotional development and protect against psychiatric illness and behavioral problems."

Search for a relative to learn more about your family history.
Where is the Seering family from?
You can see how Seering families moved over time by selecting different census years. The Seering family name was found in the USA, the UK, Canada, and Scotland between 1840 and 1920. The most Seering families were found in USA in 1920. In 1840 there was 1 Seering family living in Pennsylvania. This was 100% of all the recorded Seering's in USA. Pennsylvania had the highest population of Seering families in 1840.
Use census records and voter lists to see where families with the Seering surname lived. Within census records, you can often find information like name of household members, ages, birthplaces, residences, and occupations.


Kia Ora Stud
Kia Ora Stud
Until the recent ascendency of 'Arrowfield' under the astute stewardship of John Messara the stud in the area to produce the majority of champion stallions was Kia Ora Stud in the Segenhoe Valley near Aberdeen. During the 20th century Kia Ora stood no fewer than three champion stallions who between them won 10 championships: 10% of the national total during the 100 years. 'Magpie' won twice in 1928 and 1931; 'Midstream' three times in 1948, 1951 and 1952; 'Delville Wood' five successive titles 1953 – 1957 inclusive. Only Widden Stud exceeds this record throughout the 20th century.

1937 – Percy Miller and the Kia Ora Stud
Percy Miller was a successful businessman and a hobby breeder with half a dozen mares. In 1914 he embarked on commercial thoroughbred production and purchased the cattle property Kia-Ora, over the Pages River from the established Segenhoe Stud, just east of Scone. With manager Bert Riddle, Miller set about developing Kia-Ora as a fully operational horse stud and by 1917 was able to offer two yearlings at the Sydney Easter Sales. It was to be the start of a sustained and most remarkable breeding record. In the same year a horse called Magpie ran second in the English 2000 Guineas and eventually came to Australia where he was acquired as a stallion by Percy Miller. Over the next decade Magpie became one of Australia's leading sires producing many feature race winners at Kia-Ora including Windbag, Amounis and Talking. This became the pattern with a succession of successful sires standing at Kia-Ora. Most notable of these were Midstream and Delville Wood who also became premiership winning sires and were responsible for such champions as Shannon, Delta, Hydrogen and Evening Peal.
They were to leave a legacy in a superb brand of brood mares but most remarkable about the record of Kia-Ora was the high percentage of winners that came off the property and the huge numbers, for the times, of well-grown yearlings that were sold off the stud. This peaked with 105 yearlings offered at the 1941 Sydney Easter Sales, while there were 103 catalogued in 1928 and 99 in both 1931 and 1936 for a total of 2,862 yearlings presented for sale between 1917 and 1949. Bert Riddle was the manager through all these years but on his death in 1952, four years after Percy Miller, the stud was scaled back by the family and finally dispersed in 1957. Kia-Ora had a series of owners from then on and amongst the stallions that stood at the farm were Australian champions Gunsynd and Baguette. Despite the numbers of horses bred at Kia-Ora being far less than before the winners kept coming, including top two year old Gretel and Caulfield Guineas victor Sou'wester.
The present owners took over Kia-Ora in 2000 and have re-developed the famous stud farm returning it to its former glory and once again making it home to some of the best bred mares in Australia.


Attention as a Source of Variation in SLA
Learning a foreign language.
Learner differences in the field of could be studied from different perspectives. The reason lies in the fact that each individual is unique considering cognitive, affective and socio-cultural factors. One of the considerations in the field of individual differences is the role of attention and its different degrees in the process of language learning. This study focuses on the meaning of attention with respect to its definitions and its significant role in SLA. It discusses briefly three main approaches to the definition of attention in SLA theories namely Schmidt' noticing hypothesis, Robinson model and Tomlin and Villa's functional model of input processing. It also draws the interest of teachers to the differences exist in the field of SLA considering the role of attention in interlanguage. It concludes that teachers should recognize that not all learners have the same level of attention which is an influential factor in the process of second language learning.

How to take tilt-shift photographs
Romain Trystram
If you've ever seen a video or photo of a large object that, for some strange reason, appears to be a picture of a small scale model, there's a good chance it was made using tilt-shift photography. The technique works by photographing an object with the lens out of line with the sensor or film. This allows for a different focal distance at various points in the photo. It's an impressive technique, but can require expensive lenses.
Fortunately, Bhautik Joshi, who "couldn't justify the cost" of one such lens, decided to take matters into his own hands. His website,, lists four ways to make one, as well as more info on how this technique works. We'll focus on his "Plungercam Mini" design, as it's simple to make.
 1. Gather the parts
 You'll need a camera body that's capable of changing lenses and an old 35mm lens you don't mind damaging. You'll also need a camera-body cap, a 5cm pipe coupling, and a 5cm turnkey hose clamp.
 Finding the correct materials will be the trickiest part of the project -- try a hardware shop.
 2. Assemble the tilt mechanism
 Remove the lens back. Cut a piece of the coupling to the length of your unaltered lens, then drill out the centre of the body cap to fit the pipe. Slide the altered body cap into one side of the coupling section. Slide your altered lens into the other end of the coupling. The length of the assembly should be close to what the lens was before alteration to keep the lens's focal distance correct. Place the hose clamp over the coupling near the lens, then tighten it. Screw the body cap on to your camera to form your new lens fixture.
 3. Focus, tilt, then refocus
 Bhautik suggests you "form a sharp image of something near, then adjust the focus on to a far object while holding the lens still."
 Now, try to get two objects in focus that are separated by some distance. The same technique works for shooting video.

The Wyoming Prescription Drug Abuse Prevention Toolkit is a collaborative effort between the Wyoming Department of Health and the Wyoming Survey & Analysis Center at the University of Wyoming (WYSAC). Funded through the Wyoming Grant to Prevent Prescription Drug/Opioid Overdose-Related Deaths (PDO), this project is intended to make information about prescription drug abuse and related prevention strategies more accessible.
This website aims to provide resources for prevention workers and other stakeholders throughout the lifecycles of prevention efforts. It is modeled after the Strategic Prevention Framework (SPF), a five-step, cyclical process to help stakeholders understand and address issues of substance abuse and addiction in their communities. The SPF model includes the following components:
- Assessment – Using current data to understand local needs
- Capacity – Building partnerships and resources to have capacity to address prevention needs
- Planning – Understanding best practices related to these needs and how to effectively implement them
- Implementation – Delivering the best practices or programs selected in the previous step
- Evaluation – Taking a look at how practices were implemented and whether they led to the intended outcome
Regardless of what step a community is at in its efforts to prevent prescription drug abuse, this website will provide the information and resources they need to get started, or to enhance work that's already being done.


How Do You Fold A Document That Has Been Laminated?
1 Answers
Arjun Mitra Profile
Arjun Mitra answered
The answer to this question depends on how hard the laminated surface is. If the laminated surface is hard enough for the document to not fold, you have no choice left. You will just have to go about not folding the document or go ahead remove the lamination. Some laminations are soft in texture and can be easily folded. But once they are folded the folds will leave a permanent mark on them which will never go away.
So if you are looking to fold a laminated document then it is advisable not to do so as you could cause harm to it. What you could do is get files or folders or envelops that are bigger in size of the document and you will not have to fold the. Just avoid the idea of folding a document especially if it is an important one.

Britain to limit funding for new power-only biomass plants
Thu Jul 18, 2013 2:15pm EDT
* New biomass plants to get subsidy only if they harness heat too
* Subsidy for new plants to apply only up to 400 MW capacity
* State funding for all biomass plants to be phased out by 2027
By John McGarrity
LONDON, July 18 (Reuters) - New standalone biomass power plants in Britain will not be eligible for some subsidies unless they generate heat at the same time, under new government proposals, meaning many new plants could be cancelled, an industry lobby said.
Britain's government said on Wednesday it aimed to deny public money via guaranteed minimum power prices to dedicated biomass plants that do not generate both heat and electricity.
"The lack of a strike price for new build biomass means support for this important technology has effectively come to an end, and we urge the Government to reconsider," said Gaynor Hartnell, chief executive with the Renewable Energy Association (REA).
She said that as heat output, known as combined heat and power (CHP) could not easily be built into projects that had already been approved, many would be scrapped:
"Developers cannot simply add CHP to these projects retrospectively, so they will most likely be cancelled."
CHP is seen as much more efficient as the heat from power generation is used to warm homes and businesses.
The government is steering a landmark energy bill through parliament that aims to unlock 110 billion pounds ($168 billion) of new energy investment to replace ageing capacity and lower carbon emissions.
Policymakers also plan to restrict subsidies for biomass to 400 megawatts per plant through a different type of subsidy called the Renewables Obligation, as also outlined on Wednesday.
Restrictions on this form of subsidy will only apply to new projects and not conversions from coal-fired power planned by companies such as Drax, Britain's biggest power station.
"It is new, so-called dedicated biomass power stations that will have a cap on subsidies, and not those plants that are switching to wood from coal," a spokeswoman for Drax said.
This means that large scale, controversial imports of wood pellets to Britain will continue.
On Wednesday, Edward Davey, Britain's Secretary of State for Energy and Climate Change, told BBC Radio that importing wood and burning it as biomass was not the long-term answer to the country's energy needs, leading to suggestions that the government was reversing its previously policy of support.
Drax and other large generators switching to biomass from coal will have subsidies phased out by 2027, meaning they will then have to pay all the costs of burning wood instead of the highly-polluting fossil fuel.
"This is something we already knew and does not mark a change in government policy," the Drax spokeswoman added.
Britain's energy ministry said in a statement that it had always been clear that biomass is a transitional technology, "to be replaced by other, lower carbon forms of renewable energy in the medium to long term".
Drax has already converted 660-megawatts of output to biomass, and plans to switch two similar sized units to wood pellets by 2017.
Green groups are concerned that growth in Britain's bioenergy industry will mean the felling of virgin forests for fuel, a practice that was commonplace in Europe and North America before coal was used to power the industrial revolution.
They say that carbon footprint of harvesting trees and shipping wood pellets across the Atlantic is much higher than power companies estimate.
Drax said the fuel it imports has cut emissions in converted units by 80 percent compared with burning seaborne coal, and that the wood used, much of which is sourced in the southern United States, is certified as sustainable.
But not all plants that have switched to biomass have decided to maintain power generation.
Last week, RWE npower said it would close a newly converted 750-megawatt biomass plant at Tilbury by July 21 because of a forecast drop in UK power prices and lack of capital from the Germany-based parent RWE.
Last year Drax scrapped plans to build a new dedicated biomass plant on its site in North Yorkshire, citing the need for better government support.

The cooling system is the most critical component in a laser cutter, a well maintained system will last many years if not indefinitely, also a well maintained system will increase the cooling efficiency and life span of the laser tube.
We know that the primary cooling fluid is water, but what is the difference between distilled, deionized and tap water?
Some people recommend the use of biocides and algicides to prevent bacterial growth. But why do we disagree?
We have written this article to help explain our reasoning and methodology for recommending the use of pure distilled water as a cooling medium with no added impurities.
Distilled water has low conductivity due to the absence of mineral content. This is important due to the high voltages present in a dc excited laser. By adding impurities and additives to the system you are not only increasing the fluids conductivity but also its ability to absorb minerals and oxygen present in the surrounding environment further increasing the conductivity.
Typically a DC excited laser operates with voltages in the range of 15-65kV thats 65,000V DC, at these voltages you have to take into consideration the air gap, conductivity of surrounding materials and the capacitive coupling effect of the glass laser tube. Its hard to comprehend but at these voltage levels electricity can travel through air, glass and water. By raising the conductivity of the cooling water, you are potentially creating a shorter (less resistant) path to ground for the electricity to travel. The end result of this can be
- Output power loss
- Damage to sensitive electronic equipment
- Positively charge cooling fluid, this can cause a range of issues including galvanic corrosion, this issue is further compounded when adding sodium based impurities such as bleach.
- A ringing noise coming from the power supply.

We are not going to attempt to calculate the conductivity of the cooling medium as this value will not be of any use to anyone.
What we will try to do is educate on why we believe pure distilled water to be the ultimate cooling medium.
- Tap water – Not recommended due to the presence of naturally occurring minerals, mineral content increases the conductivity of water.
- Engineered cooling fluid – specific fluids are now available for similar applications. At this present moment we haven't found anything that is as practical as distilled water.
- Deionized water – made by running water though electrically charged resin. If you have deionized water made from distilled water that has been sitting out exposed to air, it becomes ordinary distilled water. It's fine to use this type of leftover deionized water in place of distilled water. Unless you're certain it won't affect the outcome, do not substitute one type of water for another for any application that specifies which type to use.Helmenstine, Anne Marie, Ph.D. "The Difference Between Distilled and Deionized Water." ThoughtCo, Dec. 28, 2018, _URL_-versus-deionized-water-609435.
- Distilled water – a process that involves boiling water and condensing the steam to achieve a solution with a very low to no mineral content. The quality of distilled water is affected by the process and stages used during distillation.
Bacterial growth in cooling systems is a common issue we must overcome. Bacterial growth will reduce the cooling efficiency of the fluid, and in severe cases will reduce its ability to flow. Once a bacterial free system is achieved it can be maintained by regular water changes and the use of a silver coil.
Bacteria like most living organisms need light, food, water and suitable temperature to bread and survive. Unlike humans when conditions become unfavorable bacteria will spread spore that will remain dormant until the living conditions become unfavorable again.
This is why we recommended shocking the systems to kill off all spores and bacteria before attempting to maintain a bacteria free cooling system.
Preventing bacterial growth in a cooling system
- Seal the system, ensure minimal air can circulate the system, ensure air tight seals on hoses, ensure lids are always correctly seated etc. Ensure water return hose is always below the water level to prevent the return flow from aerating the water reservoir.
- Remove light exposure, replace the clear silicone hoses for black silicon hoses. This will stop the bacteria from receiving light exposure needed to aid growth.
- Heat, even when the laser is not in use it is advisable to keep the chiller running. Lower temperatures will slow down bacterial growth. This is not always possible or practical.
- Regular water changes, we recommend changing water once every 3 months. But for a well maintained system we have seen water free of bacteria after several years.
- Insert a silver coil into your water reservoir, the oligodynamic effects will cause damage and death to cells present in the cooling water.
Algaecides and Biocide treatments
We do not recommend the usage of algaecides or biocidal treatments due to the corrosiveness of some of these solutions, not to mention the effects on the ph instability that they can caused. They are simply not required as a preventative method of maintaining a bacterial free fluid.
The only method we recommended to prevent growth is a single silver coil in the reservoir.
Known as the oligodynamic effect, silver ions bond to cellular proteins and enzymes causing damage to cells and death. Silver can be purchased inexpensively for this exact purchase in the form of a silver coil. When placed into the cooling the silver oxidising releasing ions into the cooling medium. Do not be concerned about placing metal into the cooling water, it poses no risk of increasing the conductivity of the water, this is due to the fact that silver is insoluble in water.
If absolutely necessary the only algaecide we would recommend is the Tetra brand Algae Control, its primary active chemical is Polyquaternium (WSCP) also known as Poly[Oxyethylene(Dimethyliminio)Ethylene (Dimethyliminio)Ethylene Dichloride].
We often see people advising bleach being adding to your cooling formula as a biocide, most specifically the Clorox brand. If you take a few moments to study the safety data sheet of this product you will notice the two primary ingredients.
- Sodium hypochlorite – Its corrosive properties, common availability, and reaction products make it a significant safety risk. In particular, mixing liquid bleach with other cleaning products, such as acids or ammonia, may produce toxic fumes.Source wiki
- Sodium hydroxide – is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water, and readily absorbs moisture and carbon dioxide from the air. Source wiki
The above properties make the product absolutely unsuitable for use in a cooling system with sensitive components as a long term solution.
Shocking a system with regular Chlorine based bleach and water mixture is ok as a short term solution to killing bacterial growth.
Mix chlorine based bleach with regular water at 1:4 ratio. Run this mixture around your system for 24 hours. Ensure this mixture is thoroughly flushed out the system. We recommend several flushing washes after shocking a system.
You can flush the system by draining all liquids, fill with regular tap water. Circulate for one hour, drain system and repeat.
For the final flush we recommend to flush with distilled water.
Bleeding air from your cooling loop
Pockets of localised air in the cooling loop of the laser tube will lead to a reduction in heat transfer, the larger the pocket of air the lower the efficiency of the loop to cool the specific area.
The laser tube is sensitive to temperatures greater than 25'c with long term irreparable damage being possible. air pockets located in the cooling cavities of the tubes optics, both reflective final mirror and columinating lens can lead to superheating of the optical components. This is also why bacterial growth is common to be found at either end of the tube, where conditions are hotter and more favorable for bacterial growth.
We have written an article that covers this subject in depth, we recommend having a read for yourself.
Please do not use cooling additives, they are simply not needed. If you are struggling to maintain stable temperatures in your cooling system your problem lies in your setup or chillers cooling ability, not the cooling waters ability to transfer heat.
A popular subject, we all know glass laser tubes tend to crack when filled with water and frozen. This is never a desirable scenario to find yourself in. We recommend the use of storage heaters, or if budget allows a chiller with heating function.
Antifreeze can be introduced into the system, but we would never recommend to rely on it for a long term solution as it has its trade offs.
Any antifreeze that is suitable for our specific application will have reduced thermal transfer properties. For example propylene glycol (the base chemical of most "RV Antifreeze" tends to change in viscosity and gel up in cold conditions.
Automotive antifreeze is not suitable for our application due to the presence of silicon hoses and sensitive gaskets in the chiller / water pump being susceptible to degradation.
If you absolutely have to use an antifreeze we recommend the use of 99.9% proof propylene glycol. But expect to see an increase in bacterial activity. In this case you will have to add a biocidal treatment to your cooling fluid.
Mix PG with distilled water at a 1:1 ratio.
Surfactants – a compound that lowers the surface tension of water to help with the removal of air. Once again using surfactants has its own trade offs, we recommend the best method of removing all air from a system is by using gravity


The archaeology of Film
The subject of this archeological research is the 16mm copy of the documentary WERNER HERZOG EATS HIS SHOE (USA 1980, R: Les Blank) that is in the Arsenal archive. The film shows director Werner Herzog cooking and eating his Clarks desert boots at a public performance in an American cinema. The archeological work involves examining the film's different contexts, as well as preparing a public presentation of the project results.
As opposed to films that are thought to have disappeared or have been found unexpectedly, where the opening of rusty film canisters, the rescuing from damp basements or the snatching from oblivion play a role and thus anticipate an archeological perspective, WERNER HERZOG EATS HIS SHOE is a typical "bonus film". Instead of disappearing, the film made a career as an add-on. In film seasons as well as on the DVD market, the film was predominantly relegated to the status of footnote. It effectively disappeared into the role of "add-on".
What happens if a film is removed from its cocoon of add-on and put in the spotlight? How does one reach it? What does one dig out? Which details of the history of film and cinema come to the surface? Which connections (from philosophy to art history to the world of consumers) reveal themselves?
The sub-project involves students taking part in the "Archeology of film and cinema: Theories and projects" course at the Freie Universität Berlin. A public presentation of the results could take place in January 2012. A continuation of the project, with the goal of publishing a book (e.g. a small reader about the archaeology of film without a DVD), would be feasible depending on the results. One could also think about purchasing a new film copy if this made sense and was financially feasible as part of the project.

Senior Design Projects
During the final year of studies, Chemical Engineering students complete a real-world engineering project. The project is part of the Chemical Engineering Plant Design course that teaches students the skills needed to successfully complete process design projects of realistic industrial complexity. Students work on the design projects in small teams
The technical and problem-solving abilities developed by the students relate to the chemical engineering aspects of the process design cycle to enable the synthesis and design of processes typically encountered in the chemical and related industries. The focus is on:
Knowledge of the plant design process from conceptual design through to detailed design.
- Process Synthesis using design heuristic and systematic techniques to develop and evolve process designs.
- The conceptual design and specification of process equipment with a focus on fluid flow, heat and mass transfer.
- The evaluation of safety and environmental issues related to a design.
- The expert use of design computational tools in the form of process simulators and their use in assessing and optimizing process design scenarios.
In parallel to the development of their technical abilities, the students develop professional skills to facilitate successful participation in process design activities. This includes effective written and oral communications through structured team meetings, process design reports, and presentations, and the skills necessary to effectively perform in process design teams. These include project planning and management, time keeping and professional conduct, awareness of roles, expertise and strengths of team members, compliance with management decisions and acquisition of relevant information from literature sources and outside experts.
The Senior Design Projects constitute a full process design effort starting from a business-oriented problem statement to arrive at an efficient base case process design that is later optimized in detail. The teams select suitable technologies for the process, create and discriminate between possible design alternatives, develop process flow and control diagrams, perform preliminary safety and environmental analyses, and perform a full cost analysis, and assemble a full report of the results.
The teams assign specific roles and responsibilities to team members according to areas of specialization and project needs. Leadership and autonomy are emphasized as teams are encouraged to overcome minor challenges by their own means while they are challenged to discern the appropriate time to seek outside assistance.
The Senior Design Projects are presented to an industrial evaluation board for independent assessment by professional design engineers.

In 1973, Mayor Harvey Sloan oversaw the creation of Louisville's first Landmarks Commission, modeled after an ordinance in New York City, making preservation public policy for the first time in the city. Now 39 years later, Louisville has created on average two Individual Landmarks a year, seven Landmarks Districts, a new merged government structure with new political dynamics, and the Metro Council has voted to change how preservation happens in the city.
In early February, Metro Councilmember David Yates sponsored an amendment to Louisville's Landmarks Ordinance, complaining the original system lacked oversight, accountability, and public participation. Quickly joining Yates, eight additional council members, mostly representing suburban districts around the old Urban Service District, signed on as cosponsors. The amendment was introduced in Metro Council on Thursday, February 9, 2012, and over the proceeding six months, politicians and preservationists clashed on how Landmarks designation procedures should work, resulting in a newly politicized process and additional thresholds to be met in the public petition process. But in all the arguing, Louisville missed a real opportunity for preservation reform.


The Advantages of The Early Start Denver Model (ESDM) Behavioral Therapy
The Early Start Denver Model is based on the methods used in Applied Behavior Analysis (ABA) Therapy and has demonstrated remarkable results in infants and toddlers with Autism Spectrum Disorder. We are excited to provide you with an informative post regarding the data-proven benefits of using ESDM versus non ESDM behavioral therapy approaches. ESDM is one of the few approaches of early intervention used with infants and toddlers (12-48 months) that has conclusive data support.
The Necessity of Interaction
Autism often affects young children through a lack of desire for interacting with others. This difference is not a disability in itself, but considering how every interaction an infant has stimulates learning and brain function, those children not seeking out an adequate amount of social interaction do not gain valuable social and communication skills and form critical neural pathways at the same pace as those infants whom have the desire to socially interact.
Young children learn from social interactions of all kinds. If social interaction is less exciting than toys to infants with ASD, then there will be more competing environmental variables when attempting to engage (such as television or any interesting toy). Therefore, Autism could be seen as preventing the child's desire to engage with others, which begins a domino effect of fewer opportunities to learn social cues and will affect future social interactions.
Another point to consider is that play skills are not a natural born ability. They are learned based off engagement with older siblings, parents, daycare workers etc. Pretend play provides vital building blocks for social interactions, and by utilizing the Early Start Denver Model, it provides a myriad of beneficial engagements for children with ASD.
Maximizing Opportunities to Learn
The Early Start Denver Model focuses on creating social experiences that have the child with ASD actively engaged in the family's social activities. Tasks that could appear as normal everyday routines actually have the capability to engage the child with ASD and provide learning opportunities. These activities are as simple as grocery shopping, diaper changes, going down a slide, taking a walk, and even feeding pets. These are important activities where children can learn, and ESDM emphasizes the importance of parents coaching their children as well.
The Data
Research by Geri Dawson in 2010 demonstrates the success of using the Early Start Denver Model in a controlled trial. There were 48 children with ASD between the ages of 18 months and 30 months. The groups were divided into those engaging in 15 hours per week of ESDM as well as additional parent coaching, and the others using community intervention that was available in the city of Seattle at the time. Both groups had similar amounts of time in therapy each week. The children also all had similarly matched IQs at the beginning of the trial, around 60, which is a typical range for children of that age with ASD.
One year later, the children receiving ESDM gained about 17 IQ points on average, compared to the children in the comparison community group that did not include ESDM, gained about 5. The children in the ESDM group increased their IQs so much (to 80) that they no longer fell under the range of intellectual disability.
However, the same is not true for Autism severity, as ADOS scores indicate how much of a gain they can make. The children with more severe autism in the ESDM group did better than the children with severe autism in the community group, but they did not have nearly as high of IQ gain as the children with milder autism to begin with. Neverthless, the ESDM treatment still showed gains with children with severe ASD.
Earlier studies along with Geri's came to the same conclusion: children receiving a variety of interventions do not tend to make as much progress as children who receive a highly focused, and carefully manualized and organized intervention like ESDM.
Another breakthrough for ESDM was that children in the ESDM group also showed similar responses to typical developing children when it came to brain responses to faces. They proved to have faster and stronger electrical brain responses to faces (a discovery acknowledged in Time Magazine) than they did to toys.
The community group proved to still have stronger brain responses to toys than to faces of people.
The Early Start Denver Model has revolutionized ABA therapy, and we hope this informative blog post has given you a greater insight into its effectiveness. Feel free to comment with any questions, comments or additional experiences pertaining to the Early Start Denver Model!
