Frozen iPod is nothing new for most users. In fact, it is something that is being experienced from time to time. iPod Touch is in a way durable even if they could experience freezing at some point. Fixing it could be simple, although in severe cases, the iPod Touch might be replaced.
One of the reasons leading to iPod frozen is the presence of corrupted files. When this happens, the operating system is not likely to know what to do with the file causing a freeze. Other reasons include lack of memory, physical freezes and in some cases, no battery.
Part 1 How to Fix Frozen iPod
1 Steps to Fix iPod Touch Frozen
iPod Touch is prone to freeze from time to time. However, when it happens, follow the steps below to fix it.
- First, you have to hold down the Wake/Sleep button that is found on the top of iPod Touch till a red slider comes up to the screen. Slide your finger across the slider to turn off your iPod Touch. Then restart your iPod Touch. (If the red slider never comes up even by pressing the button for 25 seconds, you need to reset it.)
- Reset the iPod Touch by holding down the Wake/Sleep button and Home button at the same time for about 10 seconds, then the Apple logo will appear.
- Connect your iPod Touch to an adapter and wait for it to charge.
- Press the Home button to check your iPod Touch's battery status.

Use of tracheobronchial tree 3-dimensional printed model: does it improve trainees' understanding of segmentation anatomy? A prospective study
3D Print Med. 2021 Jan 6;7(1):2. doi: 10.1186/s41205-020-00092-3.
Abstract
Background: This prospective study investigated whether the use of 3D-printed model facilitates novice learning of radiology anatomy on multiplanar computed tomography (CT) when compared to traditional 2D-based learning tools. Specifically, whether the use of a 3D printed model improved interpretation of multiplanar CT tracheobronchial anatomy.
Methods: Thirty-one medical students (10F, 21 M) from years one to three were recruited, matched for gender and level of training and randomized to 2D or 3D group. Students underwent 20-min self-study session using 2D-printed image or 3D-printed model of the tracheobronchial tree. Immediately after, students answered 10 multiple-choice questions (Test 1) to identify tracheobronchial tree branches on multiplanar CT images. Two weeks later, identical test (Test 2) was used to assess retention of information. Mean scores of 2D and 3D groups were calculated. Student's t test was used to compare mean differences in tests scores and analysis of variance (ANOVA) was used to assess the interaction of gender, CT imaging plane and time on test scores between the two groups.
Results: For test 1, 2D group had higher mean score than 3D group although not statistically significant (7.69 and 7.43, p = 0.39). Mean scores for Test 2 were significantly lower than for Test 1 (7 and 7.57, p = 0.03) with mean score decline for 2D group (Test 1 = 7.69, Test 2 = 6.63, p = 0.03), and similar score for 3D group (Test 1 and 2 = 7.43). There was no statistically significant interaction of gender and test score over time. Significant interaction between group and time of test was found for axial CT images but not for coronal images.
Conclusions: Use of a 3D-printed model of the tracheobronchial anatomy had no immediate advantage over traditional 2D-printed images for learning CT anatomy. However, use of a 3D model improved students' ability to retain learned information, irrespective of gender.

text: As increasing of requirements such as large number of input/output (I/O) and high operation frequency on semiconductor chips, high density, high speed and low power consumption are required for semiconductor package. In order to meet those requirements, we developed 1) low dielectric and low dielectric loss tangent (tan8) material (lowΚ material), 2) Cu line formation technology on flat surface of insulation layer. Based on those technologies, we have developed new low-Κ material and have evaluated its properties. We measured signal propagation delay of test substrate based on new low-Κ material with 50ω microstrip line and confirm it showed half of signal propagation loss and 1/4 of signal propagation variation in those of current materials. We also confirm significant difference in variation of characteristic impedance and signal transmission by time domain reflectometry (TDR) and time domain transmission (TDT). Other than those evaluations, we also measured power consumption and signal transmission property with 100ω microstrip line. We confirm developed low-Κ material show lower power consumption and variation than those of current materials and conclude that developed low-Κ material can be used for 100ω design providing lower power consumption. Furthermore, in order to evaluate influence by line designs, we made 50ω microstrip line with bending points and confirm very little influence by those micro line designs. We also confirm that obtained experimental results match with RLGC model considering skin effect and calculate breakdown of signal propagation loss by the RLGC model. This calculation show line formation technology on flat surface significantly reduce signal propagation loss, therefore, we conclude that flat surface of substrate as well as low dielectric constant and loss tangent are important. From this study, we conclude that line formation technology on flat surface, low dielectric and low loss material greatly contribute to high density, high speed and low power consumption of semiconductor package.

Black, H. (2013). Doll bones. NY: Margaret K. McElderry Books.
Zach, Polly, and Alice have been friends for many years. They enjoy playing imaginary games that involve pirates and many adventures. When Polly discovers that an old porcelain doll may be inhabited by a ghost, the adventures become very real. The three friends set out on a journey to return the doll to the grave where the ghost belongs. They must travel to a small town in Ohio to return the doll. They begin by bus, but when a strange man hassles them, they must leave the bus and take off on foot and then end up on boat. When they finally reach the right town they are dirty, exhausted, and angry with each other. They eventually find the grave for the doll and have a funeral for her before their adventure ends. This book was very eerie and mysterious. I loved the mystery and often wondered if the book was going to end up being a ghostly mystery or just a hoax put on by Polly. The theme of this book was showing how the friends are growing and changing. They face the possibility that they may grow apart from each other. As Havinghurst describes, adolescents need to learn how to get along with peers. This includes the changes in how relationships and friendships are made during adolescence. Friendships become based on shared interests, not just proximity of where our friends live.
This book could be used with grades 5-8.

Conference paper
Abstract
O'BRIEN and TOOLE (1) studied theoptical rotatory dispersion (ORD) of complexes formed by several colorless metal ions with optically active amines. They concluded that the effects were independent of the nature of the central metal ion and of the nature of the active amines, but dependent on the number of ligand molecules coordinated. SHIMURA (2) showed that for [Co(NH3)4L-leuc] (ClO4)2 [leuc = NH2CH(CO2)C2H3 (CH3)2] the presence of the optically active ligand caused an anomalous dispersion curve in the region of the first absorption band of Co(III). The present paper reports the study of the contributions to the optical activity from the dissymmetric spiral configuration

Why you Should not Suppress your Emotions
A submissive woman who does not respond assertively to her abusive partner, a man who drinks in order to escape bad moods for a moment, a person who tries to keep himself busy in order to forget his problems, are examples of people who suppress their emotions.
Many people suppress their emotions thinking that by doing so they have managed to get rid of problems but this practice usually lead to a bigger problem. Suppressed emotions usually manifests in one way or another. For example a man who has an abusive boss can turn out to be abusive towards his children. In this case this man directs his suppressed anger toward his children because he can't direct it towards his boss.
In my article "how to stop a narcissist from ruining your self-esteem" I said that, not responding assertively to an abusive narcissist is one of the things that can ruin your self-esteem.
Suppressed Emotions can bring bad Moods
One of the causes of bad moods and depression is repressed emotions. Your brain usually gives you negative emotions so that you solve a particular problem or achieve a certain goal. When your mind realises you are in the right direction towards solving that problem, it will send you positive emotions. On the other hand when your inner mind thinks that you are stuck and doing nothing to solve your problems, it will send you bad moods, sadness and depression.
Now, when you suppress the bad emotions that your inner mind is sending you so that you deal with a particular problem, it will realise that you are defying it, therefore, it will keep sending you even more intense bad moods.
Suppressed Emotions can Cause bad Dreams
I strongly agree with Alfred Adler's interpretations of dreams. One of his theories states that dreams are nothing but a reflection of what's happening in your life. Your inner mind (subconscious mind) usually uses dreams to remind you of a particular issue or to help you solve a certain problem. For example if at work you were assigned a role that you are not prepared for, you can dream of being at school, where you are being given an exam that you are not prepared for. This is because dreams usually come in symbols.
Bad dreams and nightmares are not different. Your mind can give you nightmares because there is important problem that you are trying to escape instead of dealing with it, maybe because you are afraid to face it.
Yes, the monster that was chasing you in your dreams might be a symbol of your abusive boss or any other issue that you are afraid of facing.
Suppressing Emotions and Attracting Difficult People
If you usually suppress your emotions when you are being mistreated then you can attract narcissists and abusive people.
Narcissists and abusive people usually target a victim that they can abuse without facing serious consequences. Therefore it you are too submissive you can attract them.
How to stop Suppressing your Emotions
You have to deal with the real issue that makes you suppress your emotions. In my previous article "understanding codependency" I said that fear of rejection can make a codependent person suppress his negative emotions. In this case unless he deals with his fear of rejection, build self-esteem and end codependency, he may always find it difficult to not repress his emotions.
Whether you have developed a bad habit of escaping from problems instead of dealing with them, whether it's fear that makes you suppress your emotions or whether you learned that from your childhood, it's very important to understand the root cause of that behaviour first. (See: how to stop being overly sensitive)

- This article concentrates on the history and development of punts and punting in England, for other usages see Norfolk punt and the general disambiguation pages at punt (disambiguation) and punter (disambiguation).
A punt is a flat-bottomed boat with a square-cut bow, designed for use in small rivers or other shallow water. Punting refers to boating in a punt. The punter generally propels the punt by pushing against the river bed with a pole. A punt should not be confused with a gondola, which is propelled by an oar rather than a pole.
The term "punt" has also been used to indicate a smaller version of a regional type of long shore working boat, for example the Deal Galley Punt. This derives from the wide usage in coastal communities of the name "punt" for any small clinker-built open-stem general purpose boat.
In Canada, the term punt can also refer to any small flat-bottomed boat with a square-cut bow, regardless of purpose, building material, or propulsion source.
In Australia, cable ferries are commonly referred to as punts.
Punt construction
A traditional river punt differs from many other types of wooden boat in that it has no keel, stem, or sternpost. Instead, it is built rather like a ladder with the main structure being two side panels connected by a series of 4 in (10 cm) cross planks, known as "treads", spaced about 1 foot (30 cm) apart.
The first punts are traditionally associated with the River Thames in England and were built as small cargo boats or platforms for fishermen. Pleasure punts – specifically built for recreation – became popular on the Thames between 1860 and 1880. Some other boats have a similar shape to a traditional punt – for example the Optimist training dinghy or the air boats used in the Everglades – but the most similar boat is the European Weidling a type that can be tracked back to Celtic boats built more than 2,000 years ago.
Since a punt has no keel, it draws only a few inches even when fully laden; this makes it very manoeuvrable and suitable for shallow water. A punt can be punted with equal facility in either direction; this is handy in narrow streams where turning round may be difficult. The square-cut bow gives greater carrying capacity for a given length than a boat of the same beam with a narrow or pointed bow; it also makes the boat very stable, and suitable for passengers.
Punts are still made in England to supply the tourist trade in Oxford and Cambridge or for racing purposes. The construction material of choice for most punts is wood. Fibreglass is used for some very light and narrow racing punts. The sides, the ends (known as "huffs"), and the "till" are normally made of hardwood such as mahogany. The treads are often made from teak. The bottom is made of softwood and may be replaced several times during the life of a particular boat.
A traditional punt is about 24 feet (7.3 m) long and 3 feet (0.91 m) wide. The sides are about 18 inches (0.5 m) deep. Both the bow and the stern are cut square, with a long shallow "swim"; this is to say, the underside of the boat slopes very gently at the front and the back.
Both smaller and wider punts are made. Extra large and wide punts known as ferry punts may be seen in Cambridge, where many are used as water-borne tourist vehicles. Single seater Thames punts were normally made only 2 feet (60 cm) wide, and somewhat shorter than a standard punt; very few of these are still afloat. Racing punts, which are still used by a few specialist clubs on the lower Thames, may be built even narrower. Thames punts have occasionally been adapted for other means of propulsion: including sails, tow-ropes, and paddle wheels. With the addition of iron hoops and canvas awnings, punts have also been used for camping.
The bottom of the punt is made with long, narrow planks stretching fore and aft, attached to the flat sides and the treads. In order to allow the wood to swell when it gets wet, the planks are set a small distance apart (traditionally the width of an old penny, about 1–2 mm). The gaps are caulked; this caulking normally needs to be renewed annually. The treads are attached to the sides with small wooden "knees", which may be vertical or set at an angle. The diagram above shows a punt without seats. The seats are usually just a simple board fitting against blocks on the sides, with cushions. The gaps between the treads are normally fitted with gratings to allow the passengers to keep their feet dry.
A punt can be punted with equal facility in either direction, so it is not obvious to the novice which end is the bow and which the stern; however, one end of the boat is strengthened with a short deck, usually called a "counter" or a "till" (terms from cabinet making), that extends some six feet (2 m) from that end.
The Thames punt-building tradition was that the end with the till was the stern, as shown in the diagram. The till provides some extra torsional rigidity, and is normally closed in; occasionally a locker may be built into it. A small minority of punts, such as those made from fibreglass at Magdalen College, Oxford have no single till in the usual sense, instead having very small tills at either end.
The forerunners of pleasure punts, fishing punts, usually had an additional compartment, called a "well," which extended across the width of the punt a little way in front of the till. This compartment was made water-tight, and had holes in the bottom or sides so that it could be flooded with water. It was used for keeping any caught fish.
Punt poles
A traditional punt has no tiller nor any provision for oars, sails, or motor; instead it is propelled and directed with a pole. Poles for pleasure punts are normally made of spruce, or aluminium. A normal pole is about 12–16 feet (4–5 m) long and weighs about 10 lb (5 kg). In both Oxford and Cambridge, long 16 ft (4.9 m) poles tend to be used exclusively. The bottom of the pole is fitted with a metal "shoe", a rounded lump of metal to protect the end – the shoe is sometimes made in the shape of a swallow tail.
Traditional wooden poles are preferred by many experienced punters; they are more sympathetic on the hands and make less noise on contact with the river bottom or the punt compared with an aluminium pole. Aluminium poles are considerably cheaper and stronger, so may be preferred by punt stations offering punts for hire to inexperienced punters; however, it is normally possible to choose either type.
Racing poles are generally a great deal lighter than pleasure punt poles, and aluminium is the preferred material. It is usual to carry one or two spare poles in a race, so that one can keep punting if a pole gets stuck or is dropped.
Punting technique
Punting is not as easy as it looks. As in rowing, you soon learn how to get along and handle the craft, but it takes long practice before you can do this with dignity and without getting the water all up your sleeve.
— Jerome K. Jerome, Three Men in a Boat (1889)
The basic technique of punting is to shove the boat along with a pole by pushing directly on the bed of the river or lake. In the 1870s, when punting for pleasure first became popular, the normal approach was for the passengers to sit at the stern on cushions placed against the till, and for the punter to have the run of the rest of the boat. The punter started at the bow, planted the pole, and then walked towards the stern, shoving the punt forwards. This is known as "running" the punt. It was the normal technique used to move heavy fishing punts. As pleasure punts became lighter, it became more usual for the punter to stand still – normally towards the stern – while shoving. This is called "pricking" the punt. Pricking has the advantages that the punter is less likely to walk off the end of the punt inadvertently, and that more of the punt can be used to carry passengers.
For pleasure punting, the best way to learn is to start out in a boat with a competent punter in order to watch him or her at work. After this there is no substitute for extensive hands-on practice on different stretches of river. For racing punting it is best to join a club, and to work on one's balance. Some punt racers practise by punting in canoes.
The orthodox punting position is to stand in front of the till, towards the back of the boat, and to punt from the side. Left-handers stand on the starboard side with the left leg forward; right-handers stand on the port side with the right leg forward. The leading foot is placed against one of the knees, and should not move as you punt. The back foot moves backwards and forwards as the punter makes each stroke.
Rather different traditions have grown up in Oxford and Cambridge: in Cambridge they stand on the till and punt with the open end forward, while in Oxford they stand inside the boat and punt with the till forward. The Oxford position is closer to the

Lazy Loading Design Pattern
 - Difficulty Level : Easy
 - Last Updated : 07 Feb, 2018
Lazy loading is a concept where we delay the loading of object until the point where we need it.
 - Lazy loading is just a fancy name given to the process of initializing a class when it's actually needed.
 - In simple words, Lazy loading is a software design pattern where the initialization of an object occurs only when it is actually needed and not before to preserve simplicity of usage and improve performance.
 - Lazy loading is essential when the cost of object creation is very high and the use of the object is very rare. So this is the scenario where it's worth implementing lazy loading.The fundamental idea of lazy loading is to load object/data when needed.
For Example, Suppose You are creating an application in which there is a Company object and this object contains a list of employees of the company in a ContactList object. There could be thousands of employees in a company. Loading the Company object from the database along with the list of all its employees in the ContactList object could be very time consuming. In some cases you don't even require the list of the employees, but you are forced to wait until the company and its list of employees loaded into the memory.
One way to save time and memory is to avoid loading of the employee objects until required and this is done using the Lazy Loading Design Pattern.
Lazy_Loading1
There are four common implementations of Lazy Loading pattern :
 1. Virtual proxy
 2. Lazy initialization
 3. Ghost
 4. Value holder
Virtual proxy
The Virtual Proxy pattern is a memory saving technique that recommends postponing an object creation until it is needed. It is used when creating an object the is expensive in terms of memory usage or processing involved.

interface ContactList
{
public List<Employee> getEmployeeList();
}

class Company {
 String companyName;
 String companyAddress;
 String companyContactNo;
 ContactList contactList;

 public Company(String companyName, String companyAddress,
 String companyContactNo, ContactList contactList)
 {
 this.companyName = companyName;
 this.companyAddress = companyAddress;
 this.companyContactNo = companyContactNo;
 this.contactList = contactList;
 }

 public String getCompanyName()
 {
 return companyName;
 }
 public String getCompanyAddress()
 {
 return companyAddress;
 }
 public String getCompanyContactNo()
 {
 return companyContactNo;
 }
 public ContactList getContactList()
 {
 return contactList;
 }

}

class ContactListImpl implements ContactList {
 public List<Employee> getEmployeeList()
 {
 return getEmpList();
 }
 private static List<Employee> getEmpList()
 {
 List<Employee> empList = new ArrayList<Employee>(5);

 empList.add(new Employee("Lokesh", 2565.55, "SE"));
 empList.add(new Employee("Kushagra", 22574, "Manager"));
 empList.add(new Employee("Susmit", 3256.77, "G4"));
 empList.add(new Employee("Vikram", 4875.54, "SSE"));
 empList.add(new Employee("Achint", 2847.01, "SE"));

 return empList;
 }
}

class ContactListProxyImpl implements ContactList {
 private ContactList contactList;
 public List<Employee> getEmployeeList()
 {
 if (contactList == null) {
 System.out.println("Fetching list of employees");
 contactList = new ContactListImpl();
 }
 return contactList.getEmployeeList();
 }
}

class Employee {
 private String employeeName;

 private double employeeSalary;
 private String employeeDesignation;

 public Employee(String employeeName,
 double employeeSalary, String employeeDesignation)
 {
 this.employeeName = employeeName;
 this.employeeSalary = employeeSalary;
 this.employeeDesignation = employeeDesignation;
 }
 public String getEmployeeName()
 {
 return employeeName;
 }
 public double getEmployeeSalary()
 {

 }
 public String getEmployeeDesignation()

 }
 public String toString()
 {
 return "Employee Name: " + employeeName + ",

}

class LazyLoading {
 public static void main(String[] args)
 {
 ContactList contactList = new ContactListProxyImpl();
 Company company = new Company
 ("Geeksforgeeks", "India", "+91-011-28458965", contactList);

 System.out.println("Company Name: " + company.getCompanyName());
 System.out.println("Company Address: " + company.getCompanyAddress());
 System.out.println("Company Contact No.: " + company.getCompanyContactNo());
 System.out.println("Requesting for contact list");

 contactList = company.getContactList();
 List<Employee> empList = contactList.getEmployeeList();
 for (Employee emp : empList) {
 System.out.println(emp);
 }
 }
}
Output:
Company Name: ABC Company
Company Address: India
Company Contact No.: +91-011-28458965
Requesting for contact list
Fetching list of employees
Employee Name: Lokesh, EmployeeDesignation: SE, Employee Salary: 2565.55
Employee Name: Kushagra, EmployeeDesignation: Manager, Employee Salary: 22574.0
Employee Name: Susmit, EmployeeDesignation: G4, Employee Salary: 3256.77
Employee Name: Vikram, EmployeeDesignation: SSE, Employee Salary: 4875.54
Employee Name: Achint, EmployeeDesignation: SE, Employee Salary: 2847.01
Now, In the above code have a Company object is created with a proxy ContactList object. At this time, the Company object holds a proxy reference, not the real ContactList object's reference, so there no employee list loaded into the memory.
Lazy Initialization
The Lazy Initialization technique consists of checking the value of a class field when it's being used. If that value equals to null then that field gets loaded with the proper value before it is returned.
Here is the example :
// Java program to illustrate
// Lazy Initialization in
// Lazy Loading Design Pattern
import java.util.HashMap;
import java.util.Map;
import java.util.Map.Entry;

enum CarType {
 none,
 Audi,
 BMW,
}

class Car {
 private static Map<CarType, Car> types = new HashMap<>();

 private Car(CarType type) {}

 public static Car getCarByTypeName(CarType type)
 {
 Car Car;

 if (!types.containsKey(type)) {
 // Lazy initialisation
 Car = new Car(type);
 types.put(type, Car);
 } else {
 // It's available currently
 Car = types.get(type);
 }

 return Car;
 }

 public static Car getCarByTypeNameHighConcurrentVersion(CarType type)
 {
 if (!types.containsKey(type)) {
 synchronized(types)
 {
 // Check again, after having acquired the lock to make sure
 // the instance was not created meanwhile by another thread
 if (!types.containsKey(type)) {
 // Lazy initialisation
 types.put(type, new Car(type));
 }
 }
 }

 return types.get(type);
 }

 public static void showAll()
 {
 if (types.size() > 0) {

 System.out.println("Number of instances made = " + types.size());

 for (Entry<CarType, Car> entry : types.entrySet()) {
 String Car = entry.getKey().toString();
 Car = Character.toUpperCase(Car.charAt(0)) + Car.substring(1);
 System.out.println(Car);
 }

 System.out.println();
 }
 }
}

class Program {
 public static void main(String[] args)
 {
 Car.getCarByTypeName(CarType.BMW);
 Car.showAll();
 Car.getCarByTypeName(CarType.Audi);
 Car.showAll();
 Car.getCarByTypeName(CarType.BMW);
 Car.showAll();
 }
}
Output :
Number of instances made = 1
BMW
Number of instances made = 2
BMW

Database environment introduction
A Berkeley DB environment is an encapsulation of one or more databases, log files and region files. Region files are the shared memory areas that contain information about the database environment such as memory pool cache pages. Only databases are byte-order independent and only database files can be moved between machines of different byte orders. Log files can be moved between machines of the same byte order. Region files are usually unique to a specific machine and potentially to a specific operating system release.
The simplest way to administer a Berkeley DB application environment is to create a single home directory that stores the files for the applications that will share the environment. The environment home directory must be created before any Berkeley DB applications are run. Berkeley DB itself never creates the environment home directory. The environment can then be identified by the name of that directory.
An environment may be shared by any number of processes, as well as by any number of threads within those processes. It is possible for an environment to include resources from other directories on the system, and applications often choose to distribute resources to other directories or disks for performance or other reasons. However, by default, the databases, shared regions (the locking, logging, memory pool, and transaction shared memory areas) and log files will be stored in a single directory hierarchy.
It is important to realize that all applications sharing a database environment implicitly trust each other. They have access to each other's data as it resides in the shared regions, and they will share resources such as buffer space and locks. At the same time, any applications using the same databases must share an environment if consistency is to be maintained between them.

I'm working on a problem related to Hyper Geometric Distribution; I searched the forum and found a number of posts related to it in this "advanced statistics" forum but wasn't able to find a specific thread that helps..
Let's say I have a standard playing card deck (52 cards) and am looking for the odds of: In the first 15 cards I draw, finding at least 1 King *and* at least 1 Queen.
I'm using Excel rather than have to do this by hand, so for finding a King in the first 15 cards, I have:
=1-(HYPGEOMDIST(0,15,4,52)) - which gives me ~75.6%
0 = finding none
15 = sample
4 = successes
52 = population
The odds of finding BOTH in a 15 card sequence would be roughly 0.756 squared, or 57.16%, but obviously if I draw a King in the first 15 cards, that will decrease the odds of drawing a queen. Over a small example like this one, the difference is probably negligible, but I'd like to get an idea how to calculate this for more precision on larger (and more important) problems.
Any help - either relating to how to solve this mathematically or how to bend Excel to my will - is much appreciated!

Ab Initio - Generate Records
A cool part about the Generate Records is that it can behave as an in-graph record source to the graph itself, or just to produce an output file for another graph to consume. It allows us to instantly create records for testing without having to hand-edit a file, and it can generate data in high volume just by setting up a graph.
I see a lot of questions around the Generate Records component. Apart from building basic data, people want to build the more exotic and 1-off data types that the Generate Records does not readily support.
May I offer one humble suggestion, and that is to simply forego the output content of the Generate Records except where we need to use a randomly generated string value. Apart from this, I've found far more power and flexibility in the following scenario, and it works every time it's tried.
Firstly, we need to put a couple of components on the canvas. One is the Generate Records and one is the Reformat. In the input DML of the Reformat, we will define a record with a single string field. Call it dummy[1] or some such like. We only plan to throw it away. Connect the output port of the Generate Records to the input port of the Reformat. Now the only data we need in the Generate Records, is how many records to generate. Let's use ten (10) records to start.
Now on the output DML of our Reformat, we put the record definition of the data we are actually trying to generate. For example, some wild, vectored, EBCDIC format - whatever, the output port of the Reformat will be the actual launching point of our generated data, rather than the output port of the Generate Records.
Someone once asked me, what does this buy us, exactly? I mean, we can't actually do anything with an empty, null record comming off the Reformat's output can we?
Of course we can.
We have the entire domain of the Reformat's expression editor, statements and business rules to stuff data into the output port with reckless abandon. Of course, we aren't exacely reformatting anything, more like formatting, creating data in the Reformat, manufacturing it on the fly.
And you may well ask - where does the data come from? It comes from the Reformat, which will emit one record for each record sent from the Generate Records. We are after all sending records from the Generate Records, we're just not doing anything with them. Each time a record "appears" on the input port of the Reformat, it will automatically cause the Reformat to emit a record on its output port, based on the rules we've put in the transform section of the Reformat.
Now to catch the data that the Reformat is about to produce, we can attach a Trash component, or we can attach an Output File, whatever suits.
Once we put all the rules in place, we punch the go button and our setup will manufacture ten (10) records into the Output File component. We can now examine it, review it, change, tweak or add some rules in the Reformat, then try again. Each time (in this case) we'll get ten records.
Need more data? Change the count in Generate Records - need different data? Modify the rules in the Reformat. This setup is the most flexible way to create data, and the one that will always guarantee we get the data in the DML form we are expecting.
I've seen folks take a really ugly COBOL copybook, put it on the output port of the Reformat, and flesh out the Reformat's transform to faithfully replicate the data exactly as how it would look from the source. I've also seen folks set this up to simulate a database extract, mainframe extract and XML generated output. For all practical purposes, we can manufacture any information, in any quantity and any format with this setup.
Use it in peace

Nice posting. I have used that technique a number of times and found it useful. In fact, I recommend checking in a graph with each project that generates test data as expected from the source system, for testing purposes. It saves a lot of headaches trying recreate test data later when doing enhancements, etc.
Another point worth mentioning is the "Generate Data" component which combines the Generate Records and Reformat together. It can be found under lib/layered_components/generate-with-transform.mpc. I think Chris Day wrote about this in one of his posts.

UIZE JavaScript Framework
MODULES Uize.Dom.VirtualEvents.Edge
1. Introduction
The Uize.Dom.VirtualEvents.Edge module implements virtual DOM events that can be used to detect when the mouse enters / exits nodes at specific edges.
DEVELOPERS: Chris van Rensburg
1.1. In a Nutshell
The virtual DOM events provided in the Uize.Dom.VirtualEvents.Edge module make it easy to wire up DOM nodes so that different things occur depending on at which edge the user enters a DOM node.
So, for example, you could perform a different action when the user mouses over a node from the left side than when the user mouses over the same node from the right side.
1.1.1. How It Works
Edge virtual DOM events are implemented for a node by comparing the coordinates of the mouse - at the time that a mouseover or mouseout real DOM event occurs for a node - to the coordinates of the node itself.
Based upon where the mouse is at the time that the mouseover or mouseout event is handled, an edge is determined based upon into which of four triangular divisions of the node the coordinates fall. The node is divided into four triangular segments by diagonal lines that run from top left to bottom right and from top right to bottom left. If the mouse coordinates fall into the leftmost triangular segment, then the left edge is chosen. If the coordinates fall into the topmost segment, then the top edge is chosen. If they fall into the rightmost segment, then the right edge is chosen. Finally, if they fall into the bottommost segment, then the bottom edge is chosen. If the edge at which a mouseover or mouseout event occurs corresponds to an edge for which a mouse-enter-at-edge or mouse-exit-at-edge virtual DOM event is wired, then the handler for that event will be executed.
1.1.1.1. Limitations
In the overwhelming majority of cases, the rather simple mechanism involved in determining the edge of entry or exit works quite reliably and is very accurate.
However, there are some situations where the edge determination logic can produce what could be considered faulty results. One case is where one is connecting to a machine remotely through a system such as Microsoft's Remote Desktop Protocol, where latencies can be introduced into the delivery of mouse events (that originate remotely) to the machine being controlled. While this is a somewhat rare case, the result is that a mouseover or mouseout event can be fired long after the mouse has already crossed an edge boundary of a node. Without having tracked mouse movement over time, where the mouse is at the time that the mouseover or mouseout event is first fired can provide a misleading indication of how the mouse got there. It could appear closest to the top edge, but it may have gotten there by entering from the left.
Another (more likely) case where edge determination can become confused is when a node for which a mouse-enter-at-edge or mouse-exit-at-edge virtual DOM event is wired is being partially overlapped by another node, and where it is possible to enter or exit the wired node by transitioning between the wired node and the obscuring node. Neither of the two cases mentioned sufficiently detract from the value of the edge virtual DOM events, however.

As with most third century Roman Empresses, very little is known about her. Probably of senatorial family, she became regent on her son Hostilian, when Decius and Herennius were defeated and killed in the Battle of Abrittus to sink into obscurity after her husband and sons perished. It is assumed that her ancestors settled in Etrurian lands. Herennia married Decius probably before 230 and gained the title Augusta. Her sons were Herennius Etruscus and Hostilian.

Anyone who uses solvents to extract Cannabinoids on a large scale will tell you that the solvents are expensive. Not only is it cost-effective to recover and reuse the solvents, it is wise to use only as much solvent as is necessary, and not more. Using excess solvent lengthens the purge time and reduces the capacity of your equipment.
Of course, it is also true that the more solvent you use the higher your total yield. So, a balance must be struck between using more solvent to improve yield, and using less solvent to increase productivity. On both ends of this spectrum are diminishing returns, and the cost-benefit analysis is dependent on where priorities are placed.
What many may not realize is that the solvent-to-substrate ratio has implications not only to productivity and yield, but also to purity of final product. Consider the posted graph to illustrate the concept.
The green line indicates the total yield by mass. That is: how much final product do you get as a percentage of your starting material? We must recognize that our final product is not 100% pure cannabinoid… the mass of the cannabinoids is less than the total mass of the final product. As such, the blue line indicates the amount of cannabinoids recovered as a percentage of the total starting material.
What these data indicate is that the more solvent you use the more material you capture, but the lower purity of final product. As solvent quantity increases, the amount of cannabinoid capture depreciates faster than does the amount of impurity capture.
By no means is this an argument in favor of using less solvent. There is certainly an argument for higher yield even if it sacrifices potency a little. It's a balancing act. As a producer, you should ask yourself what you desire from your extraction process. On what vertical line of this graph do you want your extraction outcome?
Note: The graph above is not to scale and depends on a number of factors including what type of solvent is being used. If you want to find out how your solvent behaves so as to maximize your outcomes, ask your laboratory to help you conduct a similar experiment.

The purpose of this NSF-funded I3 project was to creatively provide evaluation capacity-building tools and strategies to NC State's K-12 STEM outreach programs, particularly those funded by NSF, to help ensure the breadth and depth of the future U.S. STEM workforce. North Carolina State University had over 120 STEM outreach projects funded between 2003 and 2009. Among these are many funded by NSF, including the ITEST, MSP, Noyce, GSE, AGEP, CCLI, GK-12, and ERC programs. The vision for MISO is an integrated institutional structure that will allow pre-college programs to think and act strategically to meet the goals below. While the first two goals are new endeavors made possible through the proposed project, all four goals are shared among all participating K-12 STEM outreach programs:
- Provide an innovative network of support and communications among University-based outreach project directors and educational evaluation experts, creating a learning community to promote sharing of best practices and innovation that will deepen the impact of NC State's pre-college STEM programs on students' future academic and career choices.
- Develop and demonstrate a system of data-driven planning and analysis guided by best practices to facilitate longitudinal assessment of participant outcomes through development of a common STEM Outreach Evaluation Protocol as well as a database integrating records of NC State K-12 outreach participants with NC Department of Public Instruction records and university enrollment.
- Use the longitudinal assessment of outreach participant outcomes within the university-wide outreach learning community to support more seamless transitions across critical educational junctures.
- Broaden participation among underrepresented groups in pre-college STEM outreach activities through integrated recruitment and support strategies.
One important outcome of the project was the development of the S-STEM and T-STEM instruments. The S-STEM instrument emerged out of the project team's conclusion that there did not exist a well validated, reliable instrument for measuring student attitudes (i.e., self-efficacy and goal orientation) towards STEM subjects, STEM career pathways, and 21st century skills—key outcomes for critical STEM education and workforce development programs. The T-STEM similarly measured teacher's perceptions of their ability to teach STEM subjects and 21st century skills. While a few survey instruments measure related attitudinal dimensions, they do not systematically gather this data across all of the STEM subject areas. This data was central to the work of the MISO project and other projects being undertaken at the Friday Institute and thus spurred our efforts in this endeavor.
In our work reporting on the development and validation of these instruments, we have received an enthusiastic response from the STEM education research and evaluation community, witnessed in part by the large number of requests we've had in the short time it has been publicly posted. To date, the T-STEM and S-STEM surveys have been requested for use by more than 1,000 potential users. The instruments have been reported on at major conferences (e.g., NARST, AERA, ASEE, AEA) and with NSF umbrella communities such as CADRE and the MSP Knowledge Management and Dissemination (KMD) group. Within the state of North Carolina, they have already been used by both state and district wide STEM education initiatives. We are continuing to use these instruments in our own research and evaluation; and in continuing to develop, validate, and disseminating these instruments.
Please feel free to contact us with any questions. While this project is no longer active, the project team will do our best to respond and answer your queries.

Move an image
Examples of moving handles
Moving handles for different types of graphics:
Callout 1 An image "from file."
Callout 2 The drawing canvas with a drawing on it.
As with resizing, the same basic principle applies to moving most types of graphics: You select the image, and then drag it into position.
Unlike resizing, there are some minor variations, depending on the type of graphic:
 - For images on the drawing canvas, you can move both the drawing canvas and the image. Position the pointer over the image or over the border of the drawing canvas (if the drawing canvas isn't visible, click the image and it will appear). When the four-headed arrow Pointer image appears, you can drag the image or the drawing canvas.
 - For images not on the drawing canvas, the four-headed arrow does not appear. However, as soon as you begin to drag the image, a small box Pointer and move box appears next to the pointer and a special insertion point appears on the same line of text as the pointer to help guide your positioning. This is especially helpful if you're positioning an image near or inside text, as you'll see in the following section.
 - For diagrams (including organization charts), you need to select the diagram, and then position the pointer over the its border. When the four-headed arrow Pointer image appears, you can drag the diagram.

Spontanious dispersion of nanotubes in viscous polymer
Appeared in Carbon, Letter to the editor
19 December 2012
Materials scientists at Toulouse (CEMES) collaborating with ESWCT Airbus (Toulouse) have discovered when studying the nanotube wetting on polymers, that nanotubes placed on a thermoplastic polymer (PEEK) surface diffuse homogeneously in the polymer when annealing.
TEM image of interface between diffusion layer of multiwall carbon nanotubes and polymer.
The large application potential of carbon nanotube composites in aerospace industry is principally due their improved electrical and mechanical properties. So far one of the biggest obstacles of their large scale use is their tendency to form agglomerates in the matrix leading to heterogeneous composites. Recent wetting studies of carbon nanotubes of agglomerated tubes on the surface of PEEK at CEMES show, however that the tubes disperse spontaneously in the polymer when annealing. The authors propose that preferential infrared absorption of carbon nanotubes heat the tubes resulting in higher diffusion rates of the polymer along the tube axis which has the effect of dispersing the tubes in the polymer. Current studies show that the tubes are homogeneously dispersed at distances of at least 70 micrometers.

Opisthoteuthis meroSteve O'Shea, Richard E. Young, and Michael Vecchione
O. mero is known from over 100 specimens. It appears to be the most common species of the genus in New Zealand waters.
- Arms formula variable, arms IV usually shortest.
- Arms I in males without increased robustness.
- Suckers slightly larger in males (4.3-8.6% of ML) than in females (4.6-7.55% of ML).
- Males with only proximal field with greatly enlarged suckers.
- Suckers of proximal field slightly but abruptly enlarged; distal field virtually absent. Suckers 1-3 moderate in size, suckers 4 to 9-12 greatly enlarged, distally suckers decrease gradually but slightly to level of web, terminal 15-25 suckers decrease rapidly in size. [All arms apparently similar.]
- Up to 71 suckers on each arm.
- Web nodules not described.
- Cirrus length 4-10% of ML or 0.6-1.2 times maximum sucker diameter.
- First cirri between suckers 1 and 2.
Figure. Oral views of a female, 57 mm ML, and male, 54 mm ML O. mero. Drawings from O'Shea, 1999.
The above description is taken from O'Shea (1999). More details of the description of Opisthoteuthis mero can be found here.
O. persephone differs in almost always having 6 primary gill lamellae, and more suckers per arm (93). O. phillipi also has a high arm-sucker count. (Comparisons from O'Shea, 1999).
O. mero differs from all members of the genus (where males are known), except O. robsoni and O. depressa, in lacking distal fields or at least lacking an increase in sucker size in the distal fields. O. depressa differs from the other two in having more enlarged suckers on each arm of the proximal field (i.e., 16 vs 5-8). O. mero differs from O. robsoni in having a bilobular rather than a unilobular digestive gland.
The type locality: Off the northern end of New Zealand, 36°52'S, 176°19'E, 510 m. The species is known from waters virtually all around New Zealand in depths of about 400-900 m (O'Shea, 1999).

Participants will increase their understanding of what is included in a retailer's overall strategy, and the importance of being able to understand and articulate the strategy (from both a retailer's and supplier's perspective). Retailer strategy has a significant impact on category management, and needs to be defined across different buckets, including retail format, target consumer, competitive environment and private label or no name. Each of these areas will be reviewed in detail. A hands-on workshop allows participants to define the strategy for a specific retailer that they either work for, or that is their client.
- Explain how retailer strategy affects category management;
- List different examples of what may be included in a retailer strategy;
- Identify the strategies of a specific retailer; and
- State why it is important for retailers to communicate a clear and consistent strategy to consumers.
The estimated completion time of this course is 2 hours.

text: vinces99 writes: A quick glance at a world precipitation map shows that most tropical rain falls in the Northern Hemisphere. The Palmyra Atoll, at 6 degrees north, gets 175 inches of rain a year, while an equal distance on the opposite side of the equator gets only 45 inches. Scientists long believed that this was a quirk of the Earth's geometry – that the ocean basins tilting diagonally while the planet spins pushed tropical rain bands north of the equator. But a new University of Washington study shows that the pattern arises from ocean currents originating from the poles, thousands of miles away. The findings, published Oct. 20 in Nature Geoscience, explain a fundamental feature of the planet's climate, and show that icy waters affect seasonal rains that are crucial for growing crops in such places as Africa's Sahel region and southern India.

FRANCES MOORE LAPPÉ on CHANGING THE WAY WE THINK TO CREATE THE WORLD WE WANT
Frances Moore Lappé is an author, speaker, and activist. She and her daughter, Anna, founded of the Small Planet Institute, committed to helping people find ways to interrupt and reverse the progression of scarcity and powerlessness around the world: "appreciating that we humans take our cues from each other, the Small Planet Institute emphasizes the spread of stories of hope in action." Lappé's 1971 book, Diet for A Small Planet, was a touchstone in the food movement timeline, helping to expose the wasteful and environmentally harmful practices of agribusiness, particularly in meat production.
Lappé is also the author of 17 other books about world hunger, living democracy, and the environment. Some of her works include: Democracy's Edge, Getting a Grip, EcoMind, and World Hunger: 10 Myths. With a focus on the roots of the U.S. democracy crisis, and how Americans are creatively responding to the challenge, her current work includes the online Field Guide to the Democracy Movement, and forthcoming book Daring Democracy: Igniting Power, Meaning, and Connection for the America We Want, coauthored with Adam Eichen. The Smithsonian's National Museum of American History in Washington, D.C., describes Diet for a Small Planet as "one of the most influential political tracts of the times." Frances was also named by Gourmet Magazine as one of 25 people (including Thomas Jefferson, Upton Sinclair, and Julia Child), whose work has changed the way America eats. Her books have been translated into 15 languages and are used widely in university courses.

We are well aware of the fact that the Earth's crust is exceptionally hot. However, it is obvious that the rocks and all the constituents inside the Earth's crust also contain extremely hot temperatures. In a recent case, scientists discovered the hottest rock and recorded its extreme temperature as well. The rock was first discovered in 2011 by the University of Western Ontario and surprisingly small zircon grains were being discovered too. Zircons are very reliable substances, and when given high-temperature conditions, they have the capability to form crystals. But it was not obvious at that time whether there were actually zircon grains or not being found. However, later studies endorsed this fact through and through, proving that the discovery was made right.
Not only did they find this in one specific location, but they came upon it in more than one place, i.e., in different locations throughout the earth's crust, and it turned out that they were warmed up to the core with a temperature of about 4298 degrees Fahrenheit, or 2370 degrees Celsius. "The biggest implicit argument is that we're receiving a much better understanding of how hot these effects melt rocks are, which constituted when the meteorite touched the surface, and it gives us a much better idea about the history of the melt and how it cooled in this particular crater," said Gavin Tolometti, a postdoctoral student at the University of Western Ontario. "The majority of the surviving evidence, such as glass pieces and impact melt samples, were discovered near the crater bottom," he noted. "By extending this information to additional impact craters, researchers may be able to find more evidence of the temperature conditions seen in less thorough investigations of other craters."
A lot of analyses have been conducted to prove the authenticity of this research, like the one that shows that about 36 million years ago, these rocks were transmuted into meteorites and that this happened due to their hot temperature, which caused the melting. This is evidence that the recorded heat of the rocks was authentic and well researched. "It might be a step forward in attempting to comprehend how rocks have been affected by impact craters over the whole solar system," Tolometti observed. Despite these findings, the researchers are still on their way to exploring more techniques and procedures to study the rocks and find some amazing discoveries like the one recently discovered about the hottest rock in the earth's crust. The study has been published here.

Twin Cities-based artist Siah Armajani is known for his pioneering public works, which have helped to redefine the social function of art both in this country and abroad. More than simply art for public spaces, Armajani's bridges, plazas, and other public art pieces—at once utilitarian and symbolic—are intended to reflect the ideals of a democratic society and to foster discourse and learning in the communities they inhabit.
Armajani explored the bridge as a metaphor for passage in a number of his early conceptual models and works. In 1970, for example, for the exhibition 9 Artists/9 Spaces, he fashioned an 85-foot-long, rough-timbered wooden bridge. Rising quite surprisingly to a gabled peak at its middle, it sheltered a lone pine tree planted beneath. The idea of passage became decidedly more functional with Armajani's full-scale commission for the Irene Hixon Whitney Bridge, which allows pedestrians to cross the sixteen lanes of streets and highway that had severed the Garden from neighboring Loring Park for many years. The artist's design incorporates the three basic types of bridge structure: beam (across its fir-planked, horizontal span), arch (for the eastern portion), and suspension (for the western portion). To underscore the sense of transition from one part to the next, Armajani painted each half a different, atmospheric shade: pale blue for the upward arching portion and yellow, recreated from the hue that Thomas Jefferson used at his home, Monticello, for the inverted arch. Affixed to the upper lintel of the span and running in each direction across the bridge are the words of a poem—a meditation on movement, place, order, and crossing—which Armajani commissioned specially from the renowned American poet John Ashbery.


If You've Had an Organ Removed, Should You Still Massage Its Reflexology Point?
reflexology for missing organ, reflexology removed organ, organ removed
One of the questions that I am frequently asked is whether someone should massage a reflexology point if it no longer applies to them. For example, if your spleen or gallbladder was removed many years ago, you may wonder whether you should massage the organ's reflexology point. After all, you don't have the organ any more, so is it still beneficial to massage its reflexology point?
The answer is YES.
Traditional Chinese Medicine (TCM) has a broader perspective on organs than the Western medical view. The TCM perspective encompasses not only the physical organ, but also the organ's energy meridian, and its yin and yang elements.
So even though you may no longer have the organ in your body, you still have its accompanying energy meridian. The same applies not just for organs, but also for any body part such as the tonsils or appendix. The energy still exists and so does the energy meridian that runs through the area.
Your Body Is Your Home
Think of your body's energy meridians like an electrical circuit running through your home. You want your qi—your body's electrical current—to flow smoothly and abundantly. So even though you unplugged the toaster and removed it from the counter, there is still electricity going to the kitchen.
A similar analogy applies if an organ was surgically relocated to a different area in your body. That's like taking the toaster, moving it to the dining room, and plugging it in there. Even though the toaster is no longer in the kitchen, you still need to maintain the wiring in the kitchen because the electricity powers other appliances.
The same holds true for the qi flowing through your energy meridians. The qi still flows through its original location, so it's beneficial to massage the corresponding reflexology point.
Emotional Reasons for Massaging a Point
When someone has had an organ removed, they may feel regret, guilt, or shame about the missing organ. They may think, "I should have done something different. Maybe I should have gotten a second opinion." They may feel badly about the experience and their body, thinking, "I am no longer whole."
The flow of qi is affected by your thoughts so negative thinking can actually disrupt the smooth flow of qi through an area. Want to test this out? Take a second to think of something that's been bugging you lately. If you pay attention to your body, you'll notice that your breathing may have become shallower, your jaw may have clenched, or you may be tensing up one part of your body.
Now imagine what years of feeling regret, shame, and guilt can do to your body, especially when you're directing it to the same place (the missing organ) every day. So to help prevent energy blocks, massage the organ's reflexology point, and also visualize bright white light flowing through this area of your body. Bringing your focus to the area in a loving manner will help to naturally relax and release tension—and this will help keep your qi flowing smoothly.
Even if you're not missing an organ, you can always visualize loving white light surrounding any portion of your body, or even your entire body. Go ahead and try it right now. You'll be amazed at how your breathing deepens and your body relaxes. It's a simple and easy way to improve the flow of qi.

Time-dependent behavior with gel formation or curing
Figure 1: Time-dependent viscosity function of a sample with gel formation or curing: The viscosity value increases significantly after reaching time-point tS because of the gel formation or curing reaction. A previously defined viscosity value is reached at time-point tv.
This test is performed under constant shear conditions either at a constant shear rate or at a constant shear stress. In most cases, tests with controlled shear rate are preferred. One disadvantage of controlled-shear-stress tests is that, with the increase in viscosity, the resulting rotational speed will continuously decrease. This would result in the deformation velocity no longer being constant.
However, the latter is a decisive parameter for comparing the effects of shearing on the behavior of a sample. The measuring temperature is kept constant, thus providing for isothermal conditions. It is recommended that disposable measuring systems consisting of a disposable plate and a disposable dish for single use are selected. In most cases, after curing, the two parts of the PP measuring system will stick together firmly, unable to be separated or cleaned without substantial effort. The result is usually evaluated as a time-dependent viscosity function (Figure 1).
Two time-points are of relevance here: the starting time tS at the beginning of the curve slope indicating the start of gel formation or a chemical curing reaction, and the time tV when a previously defined high-viscosity value has been reached.
However, with rotational tests, it is not possible to reliably provide an answer to the questions as to when a sample becomes solid and when the sample has been cured completely. This means that the entire curing process cannot be evaluated because at one point the cured mass is no longer able to flow and becomes solid. If the maximum torque of the rheometer has been exceeded, the rheometer can no longer control the preset rotational speed or shear rate. As a consequence, the speed will continuously decrease and the viscosity will approach infinity.
This is because the viscosity value is defined by the law of viscosity, stating viscosity as the shear stress divided by the shear rate. In the case of curing, the shear rate would finally reach zero. This also means that the law of viscosity would not be applicable here.
Our recommendation: Oscillatory tests are preferred over rotational tests for evaluating gel formation and curing processes because, with oscillatory tests, materials can be examined in their solid state as well.
