Statement by Dr. Terry Brooks, executive director, Kentucky Youth Advocates
LOUISVILLE, KY – The Kentucky House has a track record that clearly values family stability and protecting children from maltreatment. Yet, on the same day as passing critical legislation that will positively impact children across the child welfare continuum, House members ensured passage of House Bill 7 that threatens efforts to improve child safety and well-being.
As we've previously shared, there is emerging evidence about the critical role of economic and concrete supports in preventing child maltreatment, including lowering chances of a substantiated abuse or neglect report for children who participate in SNAP or WIC and a decrease in child maltreatment investigations when children have continuous Medicaid or CHIP coverage. While we are glad to see that vulnerable groups, such as kids, foster youth, and kinship and fictive kin caregivers, are especially protected from the changes proposed in HB 7, the possibility remains for unintended consequences of those good intentions to improve the state's public benefits system.
We thank House Speaker David Osborne and Speaker Pro Tem David Meade for continuing to listen to feedback from stakeholders and considering key recommendations as the legislation advances, including:
- Clarifying language to allow the Cabinet for Health and Family Services' (CHFS) discretion to determine punishments for violations of fraud.
- Exempting payments made to foster, kinship, and fictive kin caregivers, as well as exempting WIC and third-party payments, such as CCAP, from requirements that public assistance programs be distributed on the same EBT card.
- Removing language around Categorical Eligibility for public benefits so children in households enrolled in SNAP can continue to automatically be eligible for free school meals.
- Requiring CHFS to develop an online Employment and Training program so families have more options to fulfill work and community engagement requirements.
- Establishing a Benefit Cliff Task Force to study bridge insurance program for low-income families and strengthen access to the Child Care Assistance Program.
As this legislation heads to the Senate, we ask for the following considerations:
- Explicitly exempt former foster youth from provisions within the legislation to ensure there are not additional barriers for this vulnerable group.
- Allow noncustodial parents who are behind on child support the ability to prove their involvement in their child's life before disqualifying them from public benefits.
- Allow Presumptive Eligibility determinations to be made by medical practitioners and various clinical sites to ensure the determination for pregnant women and children isn't limited to only hospitals.
- Strengthen the appeals process so families have the opportunity for due process before being charged with fraud.
In addition to these recommendations, we have several questions related to the bill, including but not limited to: How are former foster youth impacted by this bill? What counts as community engagement? How will mandated community engagement be monitored? Are pregnant women and former foster youth excluded from community engagement programs? What is the fiscal note for HB 7? Is ninety days enough time for the Cabinet to integrate SNAP, Medicaid, and other public assistance programs into the same EBT card?
Safety net programs play a critical role in making sure families struggling to make ends meet can have food to eat, cover basic family needs, and access critical supports and services needed to be healthy. Kentucky will be strongest when all children have their best chance to thrive as we continue to build an equitable pandemic recovery. We call on Senate leadership to consider these recommendations and questions as HB 7 progresses through the legislative process.

MySQL 8 is GA and it has a variety of new features. Recently, we happened to work with resource groups to restrict resource utilization for a MySQL thread.
That's why I thought of writing this blog post: to give you a quick introduction to resource groups, an idea of how to dynamically allocate them and to discuss a related bug report.
Introduction To Resource Groups:
A resource group, a new feature in MySQL 8, is the entity that defines the allowed resources consumption for threads pertaining to that group. Group attributes enable control over resources and hence the database threads get restricted with those limits.
Resource groups introduce the following associated components:
1. SQL to manage the resource groups (create, alter, assign, drop).
2. Resource groups related privileges.
3. The information_schema.resource_groups table, which holds groups details.
4. A new column was added to the performance_schema.threads table to show us the assignments of threads to respective resource groups.

Plan International began operating in Laos in 2008 to advance children's rights and equality for girls. We work with vulnerable children, families and communities so they can build the best possible futures for themselves.
We work with communities where there is low school enrolment and completion, poor hygiene, little-to-no access to sanitation, limited safe water and high levels of malnutrition.
Our key areas of work include:
- Providing parents with the facilities and knowledge to give their children a healthy start in life
- Providing access to quality education for all vulnerable children, particularly girls
- Improving the health of children by ensuring good sanitation and hygiene practices and providing sustainable access to clean water.
Toilets improve the health of communities
Plan International Laos is encouraging people to use and maintain hygienic toilets and is helping them understand how it will improve their health and well-being.

FLAGSTAFF, Ariz. – The sand dunes among which Navajos have eked out austere livings for generations are growing fast and becoming mobile as the climate changes, says U.S. Geological Survey geologist Dr. Margaret Hiza Redsteer, whose interviews with elders and historical research augment her decade-long research on Navajo Nation land.
Redsteer will discuss her work Friday, Oct. 21 at the annual conference of the Society of Environmental Journalists in Miami, as part of a panel on "Climate Change and Indigenous Peoples on the Frontlines."
One third of the Navajo Nation is sand dunes, much of it stabilized to varying degrees by vegetation that holds moisture and provides livestock range. Some of the dunes are very old; others date from the 1950s, when drought and wind mobilized sediment from floods on the Little Colorado River. Now, after severe drought has gripped the region with varying but persistent severity from 1996 to 2011, new dunes are increasing in number and previously inactive dunes are on the move. The new dunes form downwind from rivers and washes, largely from dry, wind-blown river sediment. In the Grand Falls area of the southwest Navajo Nation, dunes have grown 70 percent since 1995 and are moving northeast at a rate of 115 feet per year.
Dune mobility can threaten roads and buildings, as well as the livestock raising vital to the Navajo economy and indispensable to its culture. It is one of many signs of the region's increased aridity. Redsteer and the USGS Navajo Land Use Planning Project, under license to and in collaboration with the Navajo Nation, are mapping the area's geology and documenting its changes to help Navajo leaders plan for the challenge.
In addition to using ground-based lidar measurements, meteorological monitoring, GPS and aerial and satellite imaging, Redsteer drew on more than 70 elders living in the southwestern Navajo Nation to record observed changes in land use practices, as well as weather, vegetation, location of water sources and the frequency of wind and dust storms. The interviews helped corroborate USGS science.
"Old men told me that they had seen grass grow in areas where no grass grows now," Redsteer said.
"We have aerial photographic surveys of the study area from 1934 and from 1954, but between those years there were big changes. Our interviewing not only provides another line of evidence, but it also fills in a lot of the data gaps."
Redsteer's work also points up the vulnerability of indigenous people who live on land she calls "just on the edge of being habitable.
"The annual moisture here has historically been just enough to get by. When there is even a small change, there is a huge effect," she said.
John Leeper, director of the Navajo Water Management Branch of the Navajo Nation in Fort Defiance, Ariz., called Redsteer's work "critical in understanding the magnitude of the climate challenges facing the Navajo Nation due to sand dune movement and other impacts. If the current trends she identifies continue, much of the Navajo Nation will be severely impacted, and much of the Navajo Nation will become uninhabitable," Leeper said.
"The Navajo Nation is intended to be a permanent homeland for the Navajo people," he said. "However, much of that homeland may be in jeopardy if these trends can not be successfully mitigated. Not only has Margaret's work identified and documented the current trends, her work also gives us perspective on the steps that can, and must, be taken to reverse many of the most damaging of these trends. Her work will help to ensure that the Navajo people will be able to find their livelihoods here long into the future."
As part of their work, Redsteer and the USGS have conducted pilot studies of mitigations to dune movement, such as placing 2m by 2m PLA sand barriers to stabilize dunes and seeding dune areas to encourage vegetation.
"If we're going to do research for people's benefit, we have to try to see what kind of solutions there are," she said.
Redsteer's research in the Great Falls dune area is described in the USGS fact sheet "Monitoring and Analysis of Sand Dune Movement and Growth on the Navajo Nation," available online at _URL_

Several previous reports have established the Pentax Airwayscope® (Pentax AWS, S-100, HOYA-PENTAX, Tokyo, Japan) as an efficient tool for tracheal intubation in adult patients. The Pentax AWS is often successfully used with an INTLOCK blade ; to date, however, INTLOCK blades have been released for neonatal and pediatric patients only. In this case, we performed tracheal intubation using a Pentax AWS attached to a pediatric-type INTLOCK blade (ITL-P) in an adult patient fitted with a Leksell® Stereotactic frame (Elekta, Sweden). The patient weighed 45 kg and was 154 cm tall, and was scheduled for a tumor biopsy due to glioblastoma in the brain stem. The patient was preoperatively fitted with a Leksell® frame on her head. The patient was not premedicated and was monitored with electrocardiography (ECG), noninvasive blood pressure, and pulse oximetry. Following pre-oxygenation, general anesthesia was induced using propofol 4.0 μg·ml-1 with target-controlled infusion and remifentanil 0.25 μg·kg -1·hr-1. After loss of consciousness, we administered 30-mg rocuronium boluses. We initially attempted tracheal intubation first using a Macintosh laryngoscope and then a Pentax AWS, but we could not achieve tracheal intubation with either of these instruments. Upon switching to a Pentax AWS with an ITL-P, we successfully achieved tracheal intubation without any complications. Anesthesia was maintained uneventfully with 3.0 μg·ml-1 propofol and remifentanil 0.10 to 0.25 μg·kg-1·hr-1 in oxygen and air. Further study is needed to facilitate the effective use of the Pentax AWS and the ITL-P in such cases.

Shark-infested spelling makes an irresistible learning game for kids age 6 and up! Word Pirates combines spelling and logic in a game fun for adults and kids. To play, each pirate takes a turn rolling letter dice and making a word out of the letters. The goal is to build a pathway of words from the starting point to the center of the board containing pirate treasure--without getting eaten by a shark. The game is similar to Scrabble®, in that players can build off of each other's words. Players practice strategy-making, because they can plot to block their enemies' paths with rock walls.
One reviewer says award-winning Word Pirates is great for a family game night, because the "randomness of the letters rolled levels the playing field between adults and children."
WARNING: CHOKING HAZARD--Small parts. Not for children younger than three years.

Planning the database
After you have determined your data requirements, think about ways to structure the database that will optimally convey stored information to your users. You can decide how you want to structure your database before you begin conceptualizing your page layouts, or while you develop the application interface itself. Your individual workflow needs will determine exactly how and when you create your database.
You may want to sketch the database out on paper before you begin creating it. The first step is to choose the tables in the database. A database table contains collections of related entities, such as persons, objects, or events, and divides this information into horizontal rows and vertical columns. In database terminology, each table column represents a field, and each table row represents a record.
Once you have decided on the number and types of tables that will make up your database, choose the columns for each table. Columns describe the properties of each entity or record in the table. For example, you might have a database table called CONTACTS that contains the names and addresses of a group of people. The CONTACTS table might contain columns for each person's name, street, city, state, zip code, and phone number. Each horizontal row in the CONTACTS table would represent a single record for an individual, much like a trading card contains information about a particular person.
In general, it is good practice to make sure that each of your tables has a primary key column—a column that contains values unique to each row in the table. This allows you to select an exact row when searching the database. Most primary key columns consist of ID numbers, but you can use other kinds of primary keys such as government form numbers or product serial numbers.

New type of spooky slug found
Ghost slug
It might sound more like a creepy creature out of Harry Potter, but a new type of slimy slug has been found in gardens in Wales.
Most slugs you find in Britain are brown or black, have eyes, and eat plants.
But this one is all white, has no eyes, lives underground, and eats worms by sucking them in like spaghetti!
Scientists think they've found a new species, and have named it 'Selenochlamys ysbryda', or ghost slug.
The name partly comes from the Welsh word for ghost, ysbryd.
Similar slugs are found in the countries of Turkey and Georgia, where Europe meets Asia.
the blade-like teeth of a Ghost Slug
The slug's teeth are like blades
But experts say the creatures that were found in gardens in Cardiff and Caerphilly in south Wales are different.
They don't know where the ghost slugs came from, but think they may have been brought into Britain in plant pots.


text: With the advancement of photo editing software, digital documents can easily be altered, which causes some legal issues. This paper proposes an image authentication method, which determines whether an image is authentic. Unlike many existing methods that only work with images in the JPEG format, the proposed method is image format independent, implying that it works with both noncompressed images and images in all compression formats. To improve the authentication accuracy, some strategies, such as overlapping image blocks only on concurrent directions, using a two-scale local binary pattern operator, and choosing the mean deviation instead of the standard deviation, are applied. A back-propagation neural network (BPNN) is used instead of support vector machines (SVMs) for classification to make online learning easier and achieve higher accuracy. In our experiments, we used the CASIA Database (CASIA TIDE v1.0) of compressed images and the Columbia University Digital Video Multimedia (DVMM) dataset of uncompressed images to evaluate our image authentication method. This benchmark dataset includes two types of image tampering, namely image splicing and copy–move forgery. Experiments were performed using both the SVM and BPNN classifiers with various parameters. We determined that the BPNN achieved a higher accuracy of up to 97.26 %.

The mean or average change in process over time from subgroup values. The control limits on the X-Bar brings the sample's mean and center into consideration.
The range of the process over the time from subgroups values. This monitors the spread of the process over the time.
The p chart is for the fraction of defective items in a sample.
The fraction defective is the number of defective items in a sample divided by the total number of items in a sample. The fraction defective chart is used when the sample size varies. If we have a high percentage of good items, say 99%, the fraction defective is small, 0.01. In order to get any defectives in as sample from a high quality population, the sample size must be large. In many cases the sample size is all the daily production. In this situation the sample size will vary from day to day. The only statistical measure of quality would be the fraction rejected.
The np chart is for the number of defective items in a sample.
The number of defective, np, chart shows the number of defective items in samples rather than the fraction of defective items. It requires that the sample size remains constant. It has two benefits over the p chart: there is no calculation required of each sample result; it easier for some people to understand.
The c chart is for the number of defects in an item.
The number of defects, c, chart is based on the Poisson distribution. It is a plot of the number of defects in items. The item may be a given length of steel bar, a welded tank, a bolt of cloth and so on. For the control chart, the size of the item must be constant. If the chart is for the number of defects in a bolt of cloth, all the cloths must be of the same size.
The c chart can also be used for the number of defects in a fixed number of items. The number of defects per 10 bolts of cloth can be plotted on c charts just as well as the number of defects per single roll. The essential factor for using c charts is that each sample has the same opportunity for defects.
How to Interpret the X Bar R Control Charts
- To correctly interpret X bar R chart, always examine the R chart first.
- The X bar chart control limits are derived from the R bar (average range) values, if the values are out of control in R chart that means the X bar chart control limits are not accurate.
- If the points are out of control in R chart, then stop the process. Identify the special cause and address the issue. Remove those subgroups from the calculations.
- Once the R bar chart is in control, then review X bar chart and interpret the points against the control limits.
- All the points to be interpret against the control limits but not specification limits. As specification limits are provided by customer or management whereas control limits are derived from the average and range values of the subgroups.
- If any point out of control in X bar chat. Identify the special cause and address the issue.
- Process capability studies can be performed only after both X bar and R chart values are within the control limits. There is no meaning to perform process capability studies of an unstable process.


Nociceptive primary afferents: They have a mind of their own
Susan M. Carlton
 Research output: Contribution to journalArticlepeer-review
 20 Scopus citations
 Nociceptive primary afferents have three surprising properties: they are highly complex in their expression of neurotransmitters and receptors and most probably participate in autocrine and paracrine interactions; they are capable of exerting tonic and activity-dependent inhibitory control over incoming nociceptive input; they can generate signals in the form of dorsal root reflexes that are transmitted antidromically out to the periphery and these signals can result in neurogenic inflammation in the innervated tissue. Thus, nociceptive primary afferents are highly complicated structures, capable of modifying input before it is ever transmitted to the central nervous system and capable of altering the tissue they innervate.

I was brushing up on some basic vocabulary. Asked what the Japanese equivalent of "the means (of doing something)", I would use 方法. However, they've used 手段. As far as I can tell, these are (fairly) synonymous. Is there a difference? Are there places/phrases where you would use one but not the other?
I have always got by taking 方法 as method or "way of doing" and 手段 as "a means": As Tokyo Nagoya says, there is some overlap but if you know when to use method and means in English then try to do the same in Japanese.
(Hint: I think 方法 is the easiest to adopt. You could leave 手段 until after you have heard it used more.)


Windows File History
Estimated reading time of this article: 2 minutes
Windows offers a useful feature with the file history. But there are a few hurdles, so that it is useful for developers.
The file history of Windows backups regularly, e.g. every hour, all changed files to a second drive. The file properties dialog in Windows Explorer has the tab "Previous Versions". The regularly backed up old file versions are listed there. An old version of a file can be restored.
How can for an arbitrary folder the history be enabled, e.g. 'C:\Projects'?
previous file versions dialogPrevious file versions tab in Windows Explorer file properties
Windows 10 file history has the following limitations:
 1. The main drive containing the data cannot be used as a backup drive. So C: does not work.
 2. By default, only the user directory is backed up, i.e. 'C:\User\User X'.
 1. A SD card can be used as a backup drive. Alternatively, a USB stick could be used, but the SD cards are less disturbing during transport.
 2. To backup any folder, you have to add your folder to a library. Because libraries are also backed up.
In addition, it is recommended to exclude large folders or folders that are not interesting in the file history:
 -.git/objects
 - node_modules
 - target
 - dist
The effective activation of the file history is described on many other pages:

Brisker uses a gentle heating element to warm the interior temperature to ~120 degrees Fahrenheit. Warmer air spreads moisture out, so items inside the Brisker dry out and stay crunchy.
This all works because of the principles of relative humidity. With the air inside the Brisker about 40-50 degrees warmer than room temperature in your kitchen or pantry, humidity and moisture decreases inside of the Brisker relative to the humidity in your kitchen.
Here's a neat video explaining how relative humidity works.

What is the minimum real value of $z_0$ for which the following equation has a non-zero solution in $z$?
$$\tan(z) = - \frac{1}{\sqrt{ \left(\dfrac{z_0}{z}\right)^2-1 } }$$
It seems that $z_0 = \frac{\pi}{2}$ is a the threshold but I am unable to prove this.

Are you sure about min and not inf? – Kaster Feb 25 '13 at 21:11
_USER_ I haven't been very careful about "min" vs "inf". I would like to know what is the answer, however accurately it can be given. – user6818 Feb 25 '13 at 21:37
Answer is $z_0 > \frac \pi 2$, but this set doesn't have min. It has inf though. As for the difference, min is something that belongs to the set, i.e. reachable at some point, whereas inf not necessaryly, it can be outside of the set. Just like this interval -- it doesn't have min, because whatever value you choose as min you'll be able to find the value from the same interval which is less than that so called min. But inf, it is least possible number $m$ s.t. $m \le z, \forall z \in Z$. – Kaster Feb 25 '13 at 22:00

Plot both functions $y = \frac {\tan z}z$ and $y = -\frac 1{\sqrt{z_0^2-z^2}}$ (to better understand both functions' domains). Also let's consider $z>0$ domain, since both functions are even.
enter image description here
So you can see, that second function has vertical asymptote at $x = z_0$, which means it never goes beyond that line. Also, it's always negative. At the same time, $\tan z$ (as well as $\frac {\tan z}z$) is positive, and change its sign only when $z > \frac \pi2$, so the only way to those two function to intersect is when $y = -\frac 1{\sqrt{z_0^2-z^2}}$ function's asymptote lies beyond $\frac \pi2$.
So the answer is - $z_0$ to those two lines defined above to intersect is set $z_0 > \frac \pi2$. This set doesn't have minimum value, but $\inf z_0 = \frac \pi2$.
share|improve this answer
Why are you looking at the function "y= z tan z"? I would think you should look at $y = (tan z)/z" (..if you want to intersect it with "-1/Sqrt(z_0^2 - z^2)"..) – user6818 Feb 26 '13 at 1:31
You're right. I'll fix it soon. It doesn't change answer though, sine it's based on signs. – Kaster Feb 26 '13 at 1:37
I have fixed it. – Kaster Feb 26 '13 at 1:43
I've changed those equations at first because by some reason I thought it's range would be messed up, but it turned out it's not. Anyway, either way is valid. – Kaster Feb 26 '13 at 2:49

Accident statistics indicate that postcrash fire is one of the most serious threats to human life in aircraft crashes. It is also a serious threat in automotive crashes. Several methods are available to reduce this hazard. The simplest and most effective method is through control of the fuel spillage.
Aircraft crash testing has shown that fuel systems incorporating tough, flexible fuel tanks that are smooth in contour, free from rigid attachments, and mated with flexible fluid lines are capable of preventing fuel spillage during crashes involving decelerative loading above the human survival range.


extension-point element:

In the context of a particular extension, a plug-in that stands in the extender role defines the extension, typically making certain aspects of itself available to a host plug-in through the extension. It also causes the host plug-in to add certain processing elements to its environment. As an example, the following plugin.xml corresponds to a plug-in that consumes the org.aperi.myapp extension.

In a similar fashion as a plug-in, a fragment can consume or provide extensions from/to other plug-ins. These capabilities are defined in the fragment.xml file, which is similar to the plugin.xml for a plug-in, and is part of every fragment. An example of a fragment.xml that corresponds to a fragment that consumes the org.aperi.myapp extension follows:

The act of extension is quite a general concept in Eclipse, and to understand its full generality, it is useful to summarize the types of relationships that may exist between plug-in objects, extension-points, and callback objects.
 1. Multiple extension-points may exist in a host plug-in.
 2. A plug-in may act both as a host plug-in, exposing some extension-points, and as an extender plug-in, extending some plug-ins.
 3. Multiple plug-ins may extend a given extension-point.
 4. A given plug-in may extend a given extension-point multiple times.
 5. An extender plug-in may include different extensions of different host plug-ins.
 6. A single act of extension of an extension-point by a particular extension of a particular plug-in may create multiple callback objects.
 7. A plug-in can define extensions of its own extension-points.
For more information on the Eclipse plug-in architecture, see Notes on the Eclipse Plug-in Architecture (_URL_ High Level Architecture Conceptual View
The conceptual view of the Aperi architecture consists of two layers:
 * The Platform layer provides basic storage management functions such as discovery, monitoring, and control of storage assets. It also includes the basic server infrastructure needed to support an enterprise application (logging, threading, transport, container, etc).
 * The Application layer provides high-level functions, such as filesystem capacity reporting, fabric zone control, and so forth.
Process View
At a high level the Aperi Storage Manager consists of the following processes:
 * GUI
 * CLI
 * Server
 * Host agent
 * Database
In addition to the host agent the architecture depends upon SMI-S CIMOMs and SNMP agents to be deployed in the environment. Furthermore, while Aperi includes a rich-client GUI, this is not meant to preclude the development of alternative user interfaces. The components are shown in the image below:
GUI Renders GUI panels for the user and receives user input CLI Provides scriptable command-line interface for Aperi functions Server Contains core infrastructure, including discovery, control, and monitoring services; responds to GUI requests; carries out scheduled actions and receives notifications from agents Database Repository of all information collected by Aperi Host agent Provides detailed information about host filesystems and SAN visibility from the host perspective. May be replaced over time by SMI-S host agents. Responds to requests from the server and generates asynchronous notifications to the server SMI-S CIMOM Provides low-level management and monitoring capability for storage devices. Responds to requests from server and generates asynchronous notifications to the server SNMP Agent Provides low-level monitoring capability for (some) storage devices and generates asynchronous notifications to the server
The following sequence diagrams illustrate various typical flows of communication among the various components.
The first diagram illustrates the flow during a scheduled discovery:
 1. The server's scheduler kicks off the discovery process
 2. The server queries the agents (Aperi host agents, SMI-S CIMOMs, or SNMP agents) required as part
 of the discovery
 3. The agents query the devices they represent
 4. The devices return data to the agent
 5. The agents return data to the server
 6. The server stores the data in the database
The next sequence diagram illustrates the flow when an agent sends an event that triggers a re-discovery (for example, a switch may broadcast a "configuration changed" event, and Aperi needs to rediscover the configuration):
 1. The agent sends an event to the server (either because the agent noticed a change or because it
 received a notification from the device, which is not shown here)
 2. The server stores a record of the event in the database
 of the re-discovery
 4. The agents query the devices they represent
 5. The devices return data to the agents
 6. The agents return data to the server
 7. The server stores the data in the database
The next sequence diagram illustrates the flow when a GUI user invokes a configuration operation, such as creating a volume:
 1. The GUI invokes API on the server (in response to user action not shown here)
 2. The server invokes API on the appropriate agent, such as an SMI-S CIMOM
 3. The agent invokes API on the device to execute the change
 4. The device returns data to the agent
 5. The agent returns data to the server
 6. The server stores the data in the database
 7. The server returns data to the GUI
Mapping Aperi Function to the OSGi/Eclipse Component Model
Each major component of the Aperi platform is represented as an OSGi bundle and/or Eclipse plug-in. The components are organized into logical groupings called features (collections of plug-ins). Many of the plug-ins expose packages or services so that other plug-ins may leverage them. Several plug-ins also define extension points to allow exploiting applications (also plug-ins) to extend the underlying function. Notice that these features correspond to the architectural layers identified above. Server Plug-ins and Features Feature Included Plug-ins Comments org.eclipse.aperi.runtime javax.help javax.jms org.apache.derby org.apache.soap org.apache.xerces org.eclipse.aperi.log org.eclipse.equinox.common org.eclipse.equinox.jakarta.common.logging org.eclipes.equinox.jetty org.eclipse.equinox.jetty.http org.eclipse.equinox.registry org.eclipse.equinox.servlet.api org.eclipse.equinox.servlet.bridge.http org.eclipse.osgi org.sblim.cim.client org.sblim.slp org.eclipse.osgi.services org.eclipse.update.scheduler org.eclipse.update.core org.eclipse.update.configurator org.eclipse.aperi.common org.eclipse.aperi.connector This feature contains the core Eclipse runtime. That includes the base OSGi container, OSGi service definitions, the plug-in framework, and support for plug-in deployment and updates (lifecycle mgmt). This feature also contains the implementation of the OSGi HTTP Service. This service contains the servlet container and the soap implementation needed to support web services. org.eclipse.aperi.server org.eclipse.aperi.cbe org.eclipse.aperi.database org.eclipse.aperi.jobs org.eclipse.aperi.discovery org.eclipse.aperi.monitor org.eclipse.aperi.control org.eclipse.aperi.events org.eclipse.aperi.authorization org.eclipse.aperi.config org.eclipse.aperi.alerts This feature provides the platform layer of the Aperi server.

Standards, particularly storage management standards, are critical to Aperi. The Aperi Storage Manager is intended to be an exemplary consumer of the SNIA SMI-S standard for storage device management. Aperi should use SMI-S to the fullest extent possible and should serve as a model to others on how to use SMI-S successfully. SMI-S should be the first and foremost mechanism used by Aperi, but Aperi can also use other standard mechanisms such as SNMP and GS3. Finally, it is also important that Aperi be a competitive storage management application, and it is possible that there is some

Seco de los Olivos: Overview
Located in front of the coast of Almeria (southeast Spain), the Chella Bank (Seco de los Olivos in Spanish) is a seamount whose top is found at a depth of 80 metres. It is a set of elevations that houses a very rich biodiversity, including deep-sea coral reefs, cetaceans, sharks and lots of fish. Oceana is responsible for documenting this area as a partner of the LIFE+ INDEMARES project of the European Union, with the objective of turning it into a protected marine area within the Natura 2000 Network.
In the frame of this project, Oceana has obtained never before seen images of the bank with an underwater robot (ROV). As well as these videos, which reach 600 metres depth, the on board diaries which are identified with the logo LIFE+ INDEMARES illustrate the main findings of the 2010, 2011 and 2012 expeditions and also explain the threats presented by aggressive fishing and rubbish.
Oceana first documented Chella Bank in 2006 and the following year found in these waters the first carnivorous sponge observed in Spain. All the details put together up to now demonstrate that this site in the Alboran sea is an ecologically important area within the Mediterranean and it is necessary to protect it.

The earliest record of human activity in northern Europe
Parfitt, Simon A.; Barendregt, Rene W.; Breda, Marzia; Candy, Ian; Collins, Matthew J.; Coope, G. Russell; Durbridge, Paul; Field, Mike H.; Lee, Jonathan R.; Lister, Adrian M.; Mutch, Robert; Penkman, Kirsty E.H.; Preece, Richard C.; Rose, James; Stringer, Christopher B.; Symmons, Robert; Whittaker, John E.; Wymer, John J.; Stuart, Anthony J.. 2005 The earliest record of human activity in northern Europe. Nature, 438. _PHONE_. 10.1038/nature04227Full text not available from this repository. (Request a copy)
The colonization of Eurasia by early humans is a key event after their spread out of Africa, but the nature, timing and ecological context of the earliest human occupation of northwest Europe is uncertain and has been the subject of intense debate1. The southern Caucasus was occupied about 1.8 million years (Myr) ago2, whereas human remains from Atapuerca-TD6, Spain (more than 780 kyr ago)3 and Ceprano, Italy (about 800 kyr ago)4 show that early Homo had dispersed to the Mediterranean hinterland before the Brunhes–Matuyama magnetic polarity reversal (780 kyr ago). Until now, the earliest uncontested artefacts from northern Europe were much younger, suggesting that humans were unable to colonize northern latitudes until about 500 kyr ago5, 6. Here we report flint artefacts from the Cromer Forest-bed Formation at Pakefield (52° N), Suffolk, UK, from an interglacial sequence yielding a diverse range of plant and animal fossils. Event and lithostratigraphy, palaeomagnetism, amino acid geochronology and biostratigraphy indicate that the artefacts date to the early part of the Brunhes Chron (about 700 kyr ago) and thus represent the earliest unequivocal evidence for human presence north of the Alps.

Actions (login required)


The 13th technology on the manual reads:
After resolving one or more powerups gained from performing a Main action, you may pay 1 cocoa to gain an additional power-up (same Action Board)
While the main action part on the manual reads:
Pay the cost in gold as shown on the selected tile and place one of your Technology markers (wooden discs) on it to mark that you have acquired this Technology. Refer to the Appendix for an explanation of the ongoing benefit of each Technology tile.
After placing the Technology marker, advance once on one temple, depending on which column the selected Technology belongs to: for the left column, for the centre column, for the right column
Afterwards, power up one of your workers on the Alchemy (5) Action Board, unless you used the 3rd option when selecting the tile (you used a single power 4 or 5 worker to place your marker on a second-row Technology).
Therefore, you get the power-up after you have already received the technology, and advanced on a temple. Does this mean that when powering-up your die, can you immediately pay one cocoa to gain an additional power-up?
TLDR: Can you use the technology 13 power on the same die power-up you get from purchasing the technology?
No you can not.
From the FAQ file on BGG here the following Q and A is included.
Q: When do Technology benefits trigger? A: Each Technology triggers at most once during your turn. Most Technologies trigger after performing the Main action on the board (or boards) listed at the bottom of each Technology tile. No Technology will trigger during the turn when it was acquired.
I've tried to find evidence to back this up in the rules printed though and could not.

Debugging Tips for Database Abstraction
Today I want to talk about database script debugging in large systems. The main problem is that in large applications, it becomes difficult to find the source of rogue queries that, for example, broke in a recent system update.This may not readily apply to most of you, but bear with me: some day it will.
Pretend for a moment you have a database architecture where you have 2 masters (dual replication) and 2 read-only slaves. Now pretend that you have a large application with 100 different pages/scripts. You have 5 web servers with mirror copies of the application. This would be a fairly typical setup for a small, but growing company.
One day, you come into work and find out that you had a bad transaction lock that caused your system to hang all weekend. So you look at the process list and you know what query is causing the problem (because it's still stuck). The problem is that it looks suspiciously like the queries you'd find on virtually every page in your application. How do you fix this problem? An different (but related) problem is when an update initially executed on one master database server replicated to a slave and got stuck on the slave but executed fine elsewhere. What happened? Which master server got the initial query? This sort of debugging is very difficult to track down without more information such as where the query was initially sent and from what page it originated.
The primary challenge is figuring out which query came from what page in your application. The solution is to add logging straight into your queries. The implemented looks something like this:
//Get the current page or script file
//Replace out any comment tags and add in the database being connected to
$metaData = str_replace(array('/*', '*/'), array('/ *', '* /'), $source). " ($databaseHost)");
//Escape the query so the URI can't be used to inject data
$metaData = mysql_real_escape_string($metaData);
//Execute the query
$result = mysql_query("/* $metaData */ ". $query, $connection);
This solution inserts a comment into your query that gives you useful information that can be seen when looking at the raw query. MySQL uses C++ style comment blocks (the /* */) which are ignored by the parsing engine. This means you can pass data to the engine which can be useful for debugging. These comments are also replicated down to the slaves, which can be useful when you find a slave having problems with a query that came from a master server. For those of you unaware, the "URI" refers to the full URL that was typed in the address bar to access a page.
But make sure that you correctly sanitize the URI so that somebody can't arbitrarily end your comment block (with a */) and inject their own nonsense into your query. Also, considering issues like multi-byte character attacks, I don't even want to take the risk of not further escaping the data with a call to mysql_real_escape_string.
The solution we use at my work logs the web server IP, database server IP, and script path/URI. Other potential ideas are local timestamps, version information, user IDs, and session IDs.
In conclusion, this solution will help you identify the source (and sometimes the destination) of queries that are causing problems. This has been used in our production environment at work often when trying to determine what pages are producing extremely slow queries. This solution should work with any database, although my example is written for MySQL.
Happy debugging!
PHP Best Practice: Don't use INC extensions
I have been bad about updating, and this goes back to an old habit that probably has to do with human nature: as time between updates increases, there's a desire to write a "big" update, which is increasingly difficult as news-worthy events happen and are ignored. There's so many things for me to update about that I could touch on, such as the iPhone SDK update, news on IE8 passing the ACID2 test, my predictions from a year ago that were spot on (until about a week ago when all stocks tanked), and Sun buying MySQL. But I wont. Perhaps next time. So this post is small, but serves as a feeler post to help me get back into the routine. The truth is that I have several programming post drafts setting on my machine that could have been posted a long time ago if I had given them a final read-over. Those things take a lot longer than they look from the casual observer.
Today's post is a best practices post. The tip is simple: When creating a naming convention, never rely on the.inc extension. The.inc is used in some shops to denote files that serve as libraries. This is a terrible practice for a number of reasons.
First, it means deploying your library ANYWHERE requires adding the extension to your server's configurations so that it knows these files are for PHP executables. This isn't a deal breaker in most cases, but beware that if you use shared hosting environments, this sort of thing can be annoying and stall development.
The second far more practical reason is for security. When these library files are moved to a new server which has yet to be configured, they are wide open for public viewing. Because the server doesn't know they are PHP files, they are served up as text files, essentially exposing your code base for the world to see. I've seen this issue pop up in production environments where a new web server was brought online without being fully configured, causing pages to become exposed. This is the sort of business that helps cause source code leaks (remember the Facebook code leak late last year?).
Of course, this points to the greater issue that library files shouldn't be web accessible, but I have also seen this paradigm used in common CMS applications where you have a.php file include a.inc file that contains the bulk of the page logic. Here, again, you would be exposing highly sensitive application logic to the world.
If you really want to denote files differently, I prefer to use file prefixes. As in, classes might get a prefix like "class.[rest-of-filename]". Or perhaps "function.[rest-of-filename]". There's even "include.[rest-of-filename]". The point is, a prefix can't kill you because the files retain the.php extension. :) Happy coding!

After mating on the surface of the skin, in 12 hours they go back into it and lay eggs, taking bacteria with them and excreting wastes and secretions, laying 50 to 60 eggs inside the hair follicles or sebaceous glands while it takes two weeks to develop into adults. After death, their corpses become liquid and decompose inside the skin. They reproduce by a generation every 15 days. Their total lifespan is around 30 to 90 days!


\chapter{FLT - Fried Lettuce and Tomato Sandwich?} In two episodes (which first aired on October 30, 1995 and September 20, 1998), we see a statement of the form $a^{12}+b^{12}=c^{12}$, where $a$, $b$, and $c$ are natural numbers. These equations are the following. \begin{equation} 1782^{12}+1841^{12}=1922^{12}\label{funnyeqn1} \end{equation} \begin{equation} 3987^{12}+4365^{12}=4472^{12}\label{funnyeqn2} \end{equation} This may call to mind a little-known theorem. \begin{thm}[Fermat's Last Theorem, or FLT]\label{flt} The equation $x^n+y^n=z^n$ has no non-zero integer solutions for $n>2$. \end{thm} \begin{proof} I have a marvellous proof of this, but the grant funding to produce this manual is too small for me to present it here. However, interested readers may wish to see \cite{AW1995}.\\ \end{proof} A consequence of this theorem, of course, is that equations (\ref{funnyeqn1}) and (\ref{funnyeqn2}) must be incorrect. But how might one determine this without recourse to FLT? Well, if one had lots of spare time late at night (as you very well may, dear reader), one could just go ahead and multiply them out. This author, on the other hand, has a very active social life. So, we instead recall the following. \begin{lem}\label{integerproducts} The product of any two odd integers is an odd integer. The product of any two even integers is an even integer. \end{lem} \begin{proof} Look in your notes or text from Math Camp. This is one of many similar results we proved back in those good old days.\\ \end{proof} \begin{cor}\label{oddtopower} An odd integer raised to any positive integer power is an odd integer. That is, for odd $z\in\mathbb{Z}$, $z^m$ is odd for any $m\in\mathbb{N}$. \end{cor} \begin{proof} By induction. Suppose $z$ is any odd integer. \emph{Base case}: Since $z$ is odd, we know that $z^1=z$ is odd. \emph{Inductive step}: Suppose $z^n$ is odd for some $n\in\mathbb{N}$ (our inductive hypothesis). We must show that $z^{n+1}$ is also odd. Well,... $z^{n+1}$=$z^n\cdot z$ by basic properties of exponents. By our inductive hypothesis we know that $z^n$ is odd, and we began by assuming that $z$ is odd. So, $z^n\cdot z$ is the product of two odd integers and is therefore odd by Lemma (\ref{integerproducts}).\\ \end{proof} \begin{cor}\label{eventopower} An even integer raised to any positive integer power is an even integer. \end{cor} \begin{proof} This proof is nearly identical to the one above. To reduce the printing cost of this thesis and conserve some of the planet's natural resources, we omit it.\\ \end{proof} We now look back to equation (\ref{funnyeqn1}), $1782^{12}+1841^{12}=1922^{12}$, and see that we have an two even integers, 1782 and 1922, raised to positive integer powers; thus, by Corollary \ref{eventopower}, each of the results is even. Similarly, by Corollary \ref{oddtopower}, $1841^{12}$ is odd.\\ Now all that remains is to invoke one of the most powerful theorems known to mankind. \begin{thm}\label{awesometheorem} The sum of an even integer and an odd integer is an odd integer. \end{thm} \begin{proof} The proof of this theorem is so far beyond the scope of this thesis as to be nearly incomprehensible to a person of your intellect. Some of the greatest math students in the history of Colby College are currently devoting all their talents and energies to a proof, even to the extent that they have had to reduce their daily hours spent playing Dungeons and Dragons from sixteen to just two. Fortunately, they are unemployed and living in their mothers' basements, so they have little else to do.\\ \end{proof} By applying Theorem \ref{awesometheorem} to the left-hand side of Equation (\ref{funnyeqn1}), we see that this left-hand side must be odd. But we already found above that the right-hand side is even. Thus, this equation cannot be true.\\ Alas, this same argument cannot be applied to Equation (\ref{funnyeqn2}). [Why not?] However, by using a different base for our modular arithmetic, we can arrive at the same conclusion. This, my loyal and persevering reader, is left on your shoulders. So put away your video games and your crazy rock and roll records and get to work, you slacker.

Onondaga Lake's mercury levels dropping more than expected
Even though dredging and capping operations to clean up contamination in Onondaga Lake is in its early stages, a scientist consulting on the project says mercury levels are dropping better than expected.
Honeywell only began its dredging and capping operations on a part of the lake this summer, but Syracuse University professor Charles Driscoll says the decrease in mercury levels found in fish in the lake is "unbelievable" compared to where they were about four years ago.
"Now we have a ways to go; they're still above advisory levels," he says.
Onondaga Lake became contaminated due to nearby industrial operations and chemical production. A federal lawsuit required Allied Chemical, since purchased by Honeywell, to reduce PCB, benzene and mercury levels in the lake. The $451 million remediation project will take about five years.
With just one year of that work in the books, Driscoll foresees increasingly better numbers.
"We anticipate they will continue to drop," he says of mercury levels.

A precursor of the modern day helicopter, the Aerial Screw designed by Leonardo da Vinci was designed to compress air in order to obtain flight. Now you can build this model straight from da Vinci's musings and marvel at how ahead of his time he truly was. Snap together assembly, no glue required.
Recommended ages 8 and up.
Made of plastic, the assembled model measures approx. 5" H and 7" W.
Leonardo da Vinci first sketched the predecessor to the modern helicopter in the late 15th century. Dubbed the "aerial screw," this simple machine was designed to compress air to obtain flight through its unique shape. When originally designed, da Vinci's helicopter measured more than 15 feet in diameter and was made from reed, linen and wire. The four men depicted on this model represent the original four men in the sketches who stood on a central platform, turning cranks to rotate the shaft. However, due to weight constraints, this model would never have been able to take flight.
A true Renaissance man, da Vinci was everything from a sculptor to a mathematician to an anatomist. He is credited with designing many original prototypes of modern inventions.

What will happen to life on Earth when the Sun becomes a red giant?
Hi I am a novelist from Norway and I have some questions concerning the death of the sun.
If the Sun became a red giant will the Earth still be able to support life here?
Jagadheep: No, the Earth will not be able to support life if the Sun becomes a giant star. Giant stars have large radii as their name implies. When the Sun becomes a giant star, it may become so large as to engulf Earth, in which case the planet will be destroyed. Even if this does not happen, the sun will expand so far out that the temperatures on Earth will become extremely high so that all oceans will evaporate away, and there will be no water left on Earth. So, no life which depends on water will be able to survive.
When the sun starts expanding in about 5 billion years, what will be the first signs of this process?
Karen: The Sun is a relatively low mass star and as such its death will be relatively mundane (at least by Astronomical standards). The Sun's luminosity and radius have been increasing since it started life and will continue to gradually increase in this manner for another 4.5 billion years or so. When the hydrogen in the core is all used up energy generation will stop there, however it will continue in a thin shell around the core. It is this which makes the Sun expand since it heats up the outer layers more. Funnilly enough this makes the very outer layer cooler so that sun will actually redden as well as becoming brighter and expanding. I suspect that this reddening might be the first signs the the Sun has left the Main Sequence.
How long will it take from the process starts til the earth is engulfed, or at least uninhabitable?
Timescales are difficult in evolutionary models of stars. It's not clear quite what'll happen to the Earth either. It could be engulfed by the Sun, or it might get pushed out into a larger orbit and freeze as the Sun expands. The Sun will be a Red Giant for a few million years. By then I think it's safe to say that the Earth will be uninhabitable.
Will the earth catch fire while humans still live here or will the planet simply dry out?
I think that the temperature would kill life before anything caught on fire. It would only need to be 100F or so all the time for humans to be wiped out (we don't survive long in the desert, right).
Is it probable that life on earth will survive that long, or will asteroids wipe us out before then?
Probability wise, it's likely that the Human Race will have been killed off by the time the Sun leaves the Main Sequence. I don't think that any species in history has dominated the Earth for that long. Of course we could be the first....

Rebecca FosterMrs. Rebecca loves the quote, "Teaching isn't my job. It's my passion." She has had this passion from the beginning. Her teddy bears learned a lot, with her bedroom-sized chalkboard and old textbooks from her mom's elementary classroom. It was no surprise to anyone when she sought and gained her Interdisciplinary Studies (K-8) degree from Middle Tennessee State University in 2001. That fall, she began her teaching career in a self-contained 6th grade classroom. Since then, she has taught all core subject areas in grades 2, 3, 4, 5, and 6 in Rutherford County Schools. As a dedicated public school teacher, she spent countless hours planning lessons, creating materials, researching for best practices, collaborating with co-workers, and combing through student data. Her students consistently showed academic growth on state testing. She has spent the last 2 years teaching students from China online and in-person at a homeschool tutorial. She is excited to join the team of outstanding educators at Fusion Online Academy.

Reception class
The children in reception have settled in brilliantly and are beginning to build relationships with their peers. They are already so used to the different routines of the day and manage these as if they have been in school for years. You can always hear the sounds of children laughing and having fun from the reception corridor.
The adults have been challenging the children in their construction work lately. Here you can see the children selecting their own resources so that they can make their construction even better and more interesting. They worked collaboratively, sharing thoughts and ideas and adding a narrative into their play. What fantastic teamwork!
In the playground on Monday we had about 40 children working collaboratively to create a huge obstacle course. It was fantastic to stand back and watch the children support each other, come up with different ideas and work together to complete the challenge they had set for themselves. Well done Reception!or your news story here.

terminals, negative at the bottom edge of the board. Please note that this is different from the beta version. The polarity is marked on the silkscreen on the back of the board (there was no room on the front).
Warning: Do not make or break any connections while the board or the Arduino are powered. There is a high risk of destroying the drivers and/or the Arduino.
GAUPS 1.1 Example Configuration
This image (click on it to enlarge) shows an example configuration:
 - Four drivers and four motors
 - Dual-Y (two Y motors, each with its own driver)
 - Pololu DRV8825 purple high-current drivers (note that other driver modules may have the trimpot in a different location, so do not use it to decide the driver module orientation. Always check the pin labels).
 - Heatsinks
Note that the microstepping is not configured: the DIP switch is in its factory default configuration, corresponding to full stepping on all axes (not recommended).
Bottom of GAUPS 1.1 PCB, showing supply polarity
Also, when using GRBL 0.8 or 0.9 with the "invert mask" set to 0, any Pololu drivers, and the motors we carry in our store, wired as shown, for a move in the positive direction of each axis, the motors turn as follows (as viewed looking into the shaft):
Axis Motor Axis Positive Direction Motor Direction
X Right Counter-clockwise
Y Left (Y driver) Toward the back Counter-clockwise
Right (A driver) Clockwise
Z Up Clockwise
This is the standard direction of travel for a dual-motor dual-Y drive eShapeoko with any of the standard eShapeoko belt configurations (teeth down, belt going under the idler wheels and over the belt pulley). This is also valid for a Shapeoko with any of the belt mods that have the belt facing teeth down. For the original Shapeoko configuration (belt teeth up, going over the idler wheels and under the belt pulley) and any other teeth up configuration, reverse the direction of X and Y motors (by reversing the connections, black–green–blue–red instead of red–blue–green–black).
Note that not all motors from all manufacturers turn in the same direction when wired the same, although this seems to be the most common case. If your motor has different color wires, always determine the correct pairing before wiring the motors, to avoid damage to the drivers. Any configuration will work, as long as the wires in each pair are next to each other (pins 1 and 2 one pair, pins 3 and 4 another pair).
Also note that driver modules other than Pololu A4988 and DRV8825 may turn the motors in the opposite direction, too, and the direction can also be changed in firmware.
Power Supply
The choice of voltage depends on the driver modules. The kit of parts, as supplied, has capacitors rated at 35 V, so that's the maximum voltage. However, an alternative is supplied, with capacitors rated for 50 V. To keep the same form factor, these capacitors are smaller (22 µF instead of 47 µF).
With A4988 drivers, the maximum voltage is 35 V, but EMF induced in the motor during braking can raise the supply voltage, so we do not recommend using more than 30 V. The DRV8825 drivers are rated to 45 V, but, for the same reason, we do not recommend more than 40 V (provided that you are using capacitors rated 50 V or more).
A4988 and DRV8825 both work from 12 V, but the most popular voltage for them is 24 V. 19 V is also popular, because it's the typical voltage of a laptop power supply, and many people have one of those lying around.
The DRV8834 driver operates from 2.5 V to 10.8 V, so it's ideal for low-voltage applications.

For most components, numerous equivalent parts exist from various manufacturers. The given manufacturers and part numbers are just examples of compatible parts. However, except where marked with an asterisk, the supplied parts in our kit are exactly those listed here (those with an asterisk are generic equivalents). This is especially important for the long-life electrolytic capacitors of the correct form factor, and for the good quality screw terminals. Also important are the long (15 mm pins) Arduino headers; the typical Arduino headers with 10–12 mm pins are not tall enough for the solder joints on the back of the shield to clear the Arduino USB connector, and insulation is required.

District Heating – Community Heating – Heat Sharing Networks™
Traditional District heating is a system for generating heat at a central location and distributing heat at high temperatures for space heating and hot water to residential and commercial properties using heat networks. District heating plants can provide higher efficiencies and lower carbon emissions than local boilers. Some District networks also provide a cold distribution circuit to facilitate cooling.
Heat Sharing – Community Heating – Heat Networks – Decarbonising Heat
There is an alternative means of sharing heat using a lower temperature distribution circuit. This communal circuit, which is linked to a communal ThermalBank, can be accessed by each member of the group which uses its own heat pump to raise the temperature to the temperature it requires for its own heating and hot water requirements. Heat Sharing Networks™ are also termed "Cold Water Heat Networks", "Low Temperature Heat Networks", "Ambient Ground Loops", or "Fifth Generation Heat Networks".
A heat sharing circuit is cheaper to install than a high temperature circuit because it does not require the same degree of insulation to prevent heat losses to the ground. In fact, heat exchange with the ground that the pipes pass through can be beneficial: the ground adjacent to the pipes extends the contact with the ground and the pipes can draw heat from the ground.
Those buildings with excess heat can exchange heat with the Heat Sharing Network. This is more efficient for them than heat exchanging with hot external air. It also raises the temperature of the Heat Sharing Network for the benefit of those whose heat pumps need to extract heat.
Interseasonal Heat Transfer™ has many advantages for district heating. IHT can ensure that building groups have a reliable, independent and sustainable source of Renewable Heating and Renewable Cooling.
Interseasonal Heat Transfer™ can also bring On-site Renewable Energy to district heating, instead of relying on external fossil fuel supplies commonly used in Combined Heat and Power (CHP) systems.
Heat Sharing based on Interseasonal Heat Transfer can...
- provide a reliable and low-cost green energy source for space heating and cooling
- save over 70% on carbon emissions on heating compared to emissions from gas boilers
- save over 80% on carbon emissions on cooling buildings compared to emissions (from the power stations) that power electric air conditioning and electric chillers
- provide a low-cost heat energy (or cooling) source for industrial processes
- provide opportunities for reducing carbon emissions by re-cycling solar energy instead of burning fossil fuels
- provide the opportunity to recover heat from buildings with high occupancy and high passive heat gains and transfer it to buildings needing heat
- attract Renewable Heat Incentive cashback for use of ground source heat pumps
- attract Renewable Heat Incentive cashback for use of solar thermal collectors
- improve urban air quality by avoiding combustion of fossil fuels or biomass in densely populated areas
Groups of Buildings
IHT is very well suited to providing Heat Sharing to groups of houses. The cost of providing an efficient installation can be shared across a number of houses, and the benefits increase if the district heating system includes other buildings such as schools or offices whose heating and cooling requirements may follow a different daily pattern (and different weekly pattern) from the heating demand for houses. Where the district covers offices, or data centres, the heat recovered from cooling these buildings can be transferred to homes requiring heating (or other buildings with a heating need such as a community swimming pool).
Where the cooling demand is separated in time from the heating demand, surplus heat can be stored in ThermalBanks from the time it is available to the time it is needed. This efficient use of heat is at the heart of Interseasonal Heat Transfer and enables ICAX to provide cheaper heating and cheaper cooling than conventional methods, as well as proving heating and cooling with a very low carbon footprint.
Sharing heat between buildings
Many commercial buildings have an overall cooling load over the year: they have a requirement to disperse heat. This often applies to modern office buildings in south east England with extensive glazing and high solar gains. These buildings may be adjacent to older buildings with an overall annual heating load. ICAX has developed systems to allow for the transfer of heat between buildings: this form of heat transfer can save fuel and carbon emissions for both buildings.
Both buildings can benefit from a "heat sharing dividend" when they enjoy "joined up heating".
Other buildings with a need to loose excess heat include underground train tunnels, data centres and supermarkets.
A comparison of the advantages of Heat Sharing Networks over traditional gas powered District Heating is shown in the Heat Sharing Table.
District Energy Management System
ICAX has developed a District Energy Management System ("EMS") to control the transfer of thermal energy from the times and places it is most cheaply available to the times and places where it is most needed. This involves control of Thermal Energy Storage to maximise the benefits, minimise costs and minimise carbon emissions.
Even in a group of similar houses there will be variations in the heating requirements between houses: some houses will be unoccupied during the working day, others with small children, or pensioners, may have higher heating loads during the day. IHT can meet these variations in demand successfully – and meter the use of heating in different buildings.
The combined benefits make Interseasonal Heat Transfer an attractive option for offices, schools and universities, hospitals, community centres, urban and suburban housing developments, industrial developments and private houses aiming for low energy use based on solar power.
Energy Hub – sharing warmth feels good
District Heating using Interseasonal Heat Transfer combines the benefits of on-site renewable energy with sharing heating loads between neighbours.
The Intranet of Heat
This new heat sharing infrastructure is the birth of an "Intranet of Heat". The Intranet of Heat enables the exchange of information about sources and needs of heat – and cooling – and then allows heat exchange from those buildings with surplus heat to those in need of heat.

Meaning 'suspended in air' the name Meteora includes the entire rock community of 24 monasteries. There were no steps and the main access to the monasteries was by means of a net that was hitched over a hook and hoisted up by rope and a hand cranked windlass to winch towers overhanging the chasm. Monks descended in the nets or on retractable wooden ladders up to 40m long to the fertile valleys below to grow grapes, corn and potatoes.
Studies suggest that the pinnacles are formed about 60 million years ago during the Tertiary Period. Weathering and earthquakes then shaped them into their present shape.
Although it is unknown when Metéora was established, as early as the 11th century AD hermit monks were believed to be living among the caves and cutouts in the rocks.

Roots provide the foundation in the field for higher yields. Farm Journal Associate Field Agronomist Missy Bauer explains how these roots are the lifeline of the corn plant in episode 8 of Corn College TV.
"Head out with a shovel and dig up plants to see what's going on," Bauer says. "Clean up the rootball and get the extra soil off. Trim off the brace roots. They anchor soil, but they aren't the yielding power or capability of the plant."
To identify the crown roots, look and find the old seed.
"Snap that off. And at the base, the crown roots start there," Bauer explains. "They increase in diameter as the plant grows. And the first, second and third crown roots are the yielding power of the plant."
She says that those are the roots that supply most of the nutrients and water to the plant
