Lightning Data Services
What is LDS :
 LDS is Lightning Component that display the data on Page in Salesforce Lightning. Using LDS we don't need any apex controller to perform CRUD operation. using LDS we can increase the performance. It also provide the way to cache the data to work offline in case user is not connected to network. Once the connection is restored data will sync.
LDS also handle Field Level Security and sharing rules security. Record loaded in Lightning Data Services are stored in cache and shared between all components.Using LDS all component performance is increase because data is loaded once and used by many component, no need to make separate request from different-different components . when any of the component updates a record then other component will automatically updated with new value.
force:recordData :
 This tag is must be used to load the data in component using LDS.
Attributes of force:recordData :
recordId : Id of current page record that will be load
 mode : (Edit,View) its depend on what operation we are performing. If we want to update,create then Mode='Edit' else Mode='View'
layoutType : specify the layout type to display record and its determine what field are included in component.
 fields : specifies which fields in the record to query.
Target Attribute :
1. targetRecord : populate with loaded record.
2. targetField : view of loaded record.
3. targetError : populate with error.
Methods :
1. saveRecord() : insert of update the current record in force:recordData.
2. deleteRecord() : delete the current record in force:recordData.
3. getNewRecord() : load the new record instance to insert the record of that object from force:recordData.
4. reloadRecord() : reload the current record with new data.
Keep In Mind When Using It :
i. LDS is simple but it's not complete replacement of apex controller.
ii. LDS is not supported in lightning out and visualforce page. Its only for lightning.
iii. LDS perform CRUD only on single record. It's not supported for bulk data.
iv. In Summer 17, release LDS used force:recordPreview component.But now it's completely replaced by force:recordData. Difference between force:recordPreview and force:recordData is force:recordData returns record in new shape using UI API and targetfield is added in parameter.
v. To update from force:recordPreview to force:recordData is to change reference from targetRecord to targetField.
vi. If you want to query multiple operations in one transaction then use apex controller @AuraEnabled.
Example :
 Here we are creating a component that is added on Account detail page. It will create a new contact for current account record.
1. Create a new Record :
 Lightning Component :
 <aura:component implements="flexipage:availableForRecordHome, force:hasRecordId">
<aura:attribute name="newContact" type="Object"/>
<aura:attribute name="createContact" type="Object"/>
<aura:attribute name="newContactError" type="String"/>
<force:recordData aura:id="contactRecordCreator"
 layoutType="FULL"
 targetRecord="{!v.newContact}"
 targetFields ="{!v.createContact}"
 targetError="{!v.newContactError}"/>
<aura:handler name="init" value="{!this}" action="{!c.doInit}"/>

 <lightning:card iconName="action:new_contact" title="Create Contact">

<lightning:input aura:id="contactField" label="First Name" value="{!v.createContact.FirstName}"/>
<lightning:input aura:id="contactField" label="Last Name" value="{!v.createContact.LastName}"/>
<lightning:button label="Save Contact" variant="brand" onclick="{!c.handleSaveContact}"/>

</lightning:card>

 <aura:if isTrue="{!not(empty(v.newContactError))}">

 {!v.newContactError}

 </aura:if>
 </aura:component>
 Lightning Controller :
 ({
 doInit: function(component, event, helper) {
 console.log('changes');
 component.find("contactRecordCreator").getNewRecord(
 "Contact", // sObject type (entityAPIName)
 null, // recordTypeId
 false, // skip cache?
 $A.getCallback(function() {
 var rec = component.get("v.newContact");
 var error = component.get("v.newContactError");
 if(error || (rec === null)) {
 console.log("Error initializing record template: " + error);
 }
 else {
 console.log("Record template initialized: " + rec.sobjectType);
 }
 })
 );
 },
 SaveContact: function(component, event, helper) {
 component.set("v.createContact.AccountId", component.get("v.recordId"));
 component.find("contactRecordCreator").saveRecord(function(saveResult) {
 if (saveResult.state === "SUCCESS" || saveResult.state === "DRAFT") {
 var resultsToast = $A.get("e.force:showToast");
 resultsToast.setParams({
 "title": "Saved",
 "message": "New Contact ."
 });
 resultsToast.fire();
 } else if (saveResult.state === "INCOMPLETE") {
 console.log("User is offline, device doesn't support drafts.");
 } else if (saveResult.state === "ERROR") {
 console.log(JSON.stringify(saveResult.error));
 } else {
 console.log('Unknown problem, state: ' + saveResult.state);
 }
 });
 }
 })
Result :
2. Delete A record :
 Here we added Delete Component on Account Detail Page. It will Delete Current Account when we click on Delete Button in below component.
Lightning Component :
<aura:component implements="flexipage:availableForRecordHome,force:hasRecordId">
 <aura:attribute name="recordError" type="String" access="private"/>
 <force:recordData aura:id="dataRecord"
 recordId="{!v.recordId}"
 fields="Id"
 targetError="{!v.recordError}"
 recordUpdated="{!c.handleRecordUpdated}"/>

 <lightning:card iconName="delete" title="Delete Record">

<lightning:button label="Delete Record" variant="destructive" onclick="{!c.handleDeleteRecord}"/>

 </lightning:card>

 <aura:if isTrue="{!not(empty(v.recordError))}">

 {!v.recordError}

 </aura:if>
</aura:component>
Lightning Controller :
({
handleDeleteRecord: function(component, event, helper) {
 component.find("dataRecord").deleteRecord($A.getCallback(function(deleteResult) {
 if (deleteResult.state === "SUCCESS" || deleteResult.state === "DRAFT") {
 console.log("Record is deleted.");
 } else if (deleteResult.state === "INCOMPLETE") {
 console.log("User is offline, device doesn't support drafts.");
 } else if (deleteResult.state === "ERROR") {
 console.log('Problem deleting record, error: ');
 } else {
 console.log('Unknown problem, state: ');
 }
 }));
 },
 handleRecordUpdated: function(component, event, helper) {
 var eventParams = event.


Suppose one has two locally finite quasivarieties $\mathcal{V}$ and $\mathcal{W}$.
Further suppose that:
 1. $\mathcal{V}$ is a variety.
 2. The finite algebras $\mathcal{V}_f$ are dually equivalent to $\mathcal{W}_f$.
Does it follow that $\mathcal{W}$ is also a variety?
Background: This question fits into the area of 'Natural duality'. I am hoping someone can provide a counterexample, or perhaps provide additional conditions.
Here is a way to manufacture such examples. Let $\mathcal{V}$ be a locally finite variety such that (i) $\mathcal{V}$-epis are surjective, (ii) $\mathcal{V}_f$ has an injective cogenerator $A$. Define the algebra $B$ to have the same carrier as $A$, its finitary operations between all $\mathcal{V}$-morphisms $A^n \to A$. Further define $\mathcal{W} := \mathcal{Q}(B) = \mathbb{S}\mathbb{P}(B)$ to be the quasivariety generated by $B$. Then $\mathcal{V}_f$ is dually equivalent to $\mathcal{W}_f$ via the contravariant hom-functors for $A$ and $B$, endowed with additional algebraic structure.
e.g. Let $\mathcal{V} = \mathsf{Vect}(\mathbb{F})$ for a finite field $\mathbb{F}$ and take $A = \mathbb{F}$. Then $\mathcal{W}$ is essentially $\mathcal{V}$ again, where every linear combination of variables is viewed as an operation.
Here is a counterexample.
Let $A = \langle \{0,1\}; d, s\rangle$ be the algebra on $\{0,1\}$ whose defining operations are the discriminator operation $d$ on $\{0,1\}$ and the "switch" ($s(0)=1$, $s(1)=0$). According to the NU Duality Theorem of natural duality theory, $A$ is dualizable, and the topological quasivariety dual to $\mathcal V:=SP(A)$ is $\mathcal W:=S_cP(\langle \{0,1\}; s, {\mathcal T}\rangle)$, where $\mathcal T$ is the discrete topology.
I am allowing the empty algebra, else the duality doesn't work out perfectly (empty is dual to singleton in both directions).
It follows from Jonsson's Lemma that $\mathcal V:=SP(A)$ is a variety, but it is easy to see that $\mathcal W_f$ is not the finite part of a variety. $\mathcal W_f$ is the finite part of the quasivariety of $\mathbb Z_2$-sets having no fixed points, while the variety generated by $\mathcal W_f$ contains all $\mathbb Z_2$-sets.

Published Tuesday, 29th January 2019 in Research news
An extensive scientific survey among Scottish supermarkets and butchers aims to determine the prevalence of bacteria such as "E. coli" and "Salmonella" in mince.
In the first such survey of fresh beef mince at retail level in Scotland, the year-long project will study 1,000 samples from retail outlets across the country.
The project team hope this will allow them to identify any possible seasonal or geographical patterns associated with microbial contamination.
Commissioned by Food Standards Scotland (FSS) and led by SRUC, the survey will generate an up-to-date evidence base that provides estimates of the prevalence of microbiological pathogens that can cause disease, such as E. coli O157. It will also provide estimates of the prevalence of hygiene indicator bacteria and the presence of antimicrobial resistance (AMR).
Led by scientists from SRUC's Epidemiology Research Unit in Inverness, the survey will involve three Scientific Services Laboratories, two Scottish Microbiological Reference Laboratories as well as input from the Food-Borne Pathogens Group at the University of Aberdeen.
Dr Marianne James from Food Standards Scotland said: "The results of this survey will help provide evidence on the microbiological quality of mince on retail sale in Scotland. We will be able to use this information to help businesses and consumers control these risks. Any contamination of mince shouldn't however present a risk to consumers as long as it hygienically handled and cooked thoroughly."
The sampling programme will take place between January and December 2019, with a report due to be published next year.

How do I attach ribbon to pointe shoes?
To attach the ribbons, fold the bottom of each ribbon for extra strength, then lay the folded end along the pencil mark you've made, with the back edge of the ribbon aligned with the line. Choose a strong thread that won't fray the satin u2013 many dancers prefer dental floss!
Can you go on pointe in demi pointe shoes?
The toe box of a demi-pointe shoe is reinforced, but there is no hard shank (reinforced insole) inside the shoe, making it impossible to dance on pointe in a pair of demi-pointe shoes.
Why do you have to sew pointe shoes?
Some dancers sew the elastics near the ribbons, which helps conceal them once the ribbons are tied, while others sew them at the back of the heel, on the outside of the shoe, to avoid chafing the Achilles tendon.
How tight should the elastic be on pointe shoes?
Sewing Elastics to Pointe Shoes Allow about 1 inch (or a thumbs' width) of space between the two ends of the elastic, and make sure it's snug but not too tight to cut off circulation.
Why do ballerinas cut their feet with razors?
Some dancers have strange rituals, such as blowing into their shoes before putting them on, or covering their feet in glue and other chemicals to make them stick, or, even more dangerously, cutting their feet with scissors and razor blades.
Can ballerinas stand on their toes without pointe shoes?
TRUTH: Pointe shoes are designed to encase your toes and support your foot when you're en pointe; it's not advisable to go on your toes in any other shoe (or barefoot) that isn't specially designed to support you in that position.
Why do ballerinas sew their shoes?
Let's take a look inside their pointe shoe preparation process! The first step, which is common among all ballet dancers, is sewing ribbon and elastic on the shoes so that they stay secure on the foot while hopping, turning, and balancing. After that, dancers bend the shoes to "break it in" so that they form to the foot.

Woods PTO Shaft: Everything You Need to Know
PTO shaft
Introduction
The Woods PTO shaft is a crucial component in various machinery applications. It connects the power source to the implement, enabling the transfer of power for efficient operations. In this article, we will explore the different aspects of the Woods PTO shaft, its advantages, types, and how to select or customize the right PTO shaft for your specific needs and conditions.
What is PTO Shaft?
PTO shaft
A PTO (Power Take-Off) shaft is a mechanical drive shaft that connects the power source (such as a tractor or engine) to the implement (such as a rotary mower or baler). It transfers mechanical power from the power source to the implement, allowing it to perform its intended function.
Key Points:
 - PTO shafts enable the transfer of power from the power source to the implement
 - They are crucial for various machinery applications
 - PTO shafts ensure efficient power transmission
Advantages of PTO Shaft

text: Data center networks often use densely interconnected topologies to provide high bandwidth for internal data exchange. In such network, it is critical to employ effective load balancing schemes so that the bandwidth resources can be fully utilized. A simple and widely adopted scheme is equal-cost multi-path (ECMP) routing, which is generally supported by commodity switches and routers. However, research shows that ECMP cannot always ensure even traffic distribution among multiple paths. Consequently, ECMP cannot guarantee optimal resource utilization. We propose a scheme to complement ECMP with per-flow reroute. The basic idea is to perform ECMP-based load balancing by default. When a congestion occurs on a certain link, we dynamically reroute one or a few big flows to alternative paths to alleviate the congestion. The main contribution of our research is to design a scheme that enables per-flow reroute without introducing any modifications to IP switches and routers. All the flow-based operations and reroute functionalities are implemented in software that are installed on end hosts and centralized controllers. We call this scheme PROBE (Probe and RerOute based on ECMP). PROBE uses a traceroute-like approach to discover alternative paths and modifies packet headers to enable flow-based reroute. We show that PROBE is a low cost, low complexity and feasible scheme that can be easily implemented in existing data center networks that consist of commodity switches and routers.

Calculating Cooling Capability for your equipment
Simple Formula for Heat Rejection Capacity Calculation
The cooling tower suppliers have to take into account many factors such as wet bulb temperature (What is wet bulb temperature?), circulating water rate, inlet and outlet water temperature that decide the design condition for cooling tower. In other words, knowing these factors is beneficial to meet customer's requirement. In general, customers firstly need to know the quantity and heat requirement for equipment, and then decide the refrigeration ton of cooling tower. The formula is as below:
Generally, customers need to know the quantities and heat requirement of facilities to decide the model of cooling tower. Formula to calculate heat requirement as follow:
 - T1: Inlet water temperature to equipment (℃ ℉)
 - T2: Outlet water temperature from equipment (℃ ℉)
 - m: Water flow rate (L/min))
 - Q: Heat rejection produced by equipment (Kcal/h)
Simple Formula to calculate Heat Rejection Capacity: Q= (T2-T1) x m
From above formula, we can know the demand for heat dissipation of production equipment.
Calculation of Heat Rejection Capacity and Selection of Cooling Tower
If a factory needs the cooling tower to carry out on cooling, the equipment usually include:
 1. Water cooled chiller
 2. Oil temperature heat exchanger for blow molding machine
Requirement of water cooled chiller
 - T1 Inlet water temperature to chiller: 33℃
 - T2 Outlet water temperature after heat exchange: 38℃
 - M Water flow rate for chiller: 6000 liter/h
 - Heat rejection capacity calculation: Q = (38-33)*6000= 30,000 Kcal/h
Requirement of oil temperature heat exchange for blow molding equipment
 - T1 Inlet water temperature to heat exchanger: 33℃
 - T2 Outlet water temperature after heat exchange: 36℃
 - M Water flow rate for chiller 6000 liter/hr
 - So, the total heat rejection capacity needs about 48,000 Kcal/h (18000+30000)
Heat rejection capacity calculation: Q = (36-33)*6000= 18,000 Kcal/h
So, We total need calorific capacity about 48,000 Kcal/h(18000+30000)
After knowing the heat rejection capacity, there are three ways to choose cooling tower:
Using cooling tower comparison list to find suitable cooling tower that meets the heat rejection capacity for your equipment. The customers can provide these information such as local wet but temperature, circulating water flow rate, inlet and outlet water temperature for equipment to the suppliers to choose a suitable cooling tower.
Actually, current cooling tower companies have their own cooling condition, data, and experience for the selection of tower. On final decision, it's necessary to consider water quality, limescale (Know the relationship between cooling tower and limescale?), and climate exchange which contribute to weaker cooling capacity. Therefore, the decision of cooling capacity should bigger than the information customers provide, ensuring the stable cooling capacity for equipment.

"Femicide is any form of violence exercised on women on the basis of an alleged male superiority, through both physical and psychological enslavement." This is the definition of a new term coined due to the growing number of acts of violence against the female gender.
But is this number really growing? Statistics confirm this: every two days in Italy a woman is killed by her partner, without taking into account all other types of non-domestic violence. From murder to rape, from stalking to verbal insult, the types of violence are numerous, but they all affect the victim both psychologically and physically.
The age range of executioners and victims vary, but generally the former are between 31 and 50 years old, while the latter, much younger, between 18 and 31. However, femicide is also increasing at the expense of older women, between 71 and 80 years old.
Although the phenomenon is so widespread and above all serious, the sentences received are not equivalent to the crime inflicted.

Anosov $C^{1}$-diffeomorphism. Smale and Williams (see [H(1970)]) proved the following nice theorem. \proclaim {Theorem 4.1} Assume that the set of periodic points of $T$ is dense in $\bom$. If $F$ is a compact invariant subset of $\bom$ satisfying $\text {\rm codim}_\bom\ F \ge 1$, then $\text {\rm codim}_\bom\ F \ge 2 $. \endproclaim The combination of Theorem 4.1 with our weak Lemma 2.1 provides a strong ball-avoiding statement for smooth systems: \proclaim {Corollary} For any $B \neq \emptyset \subset \bom$ open, $A_\Bbb Z(B)$ is a closed set of topological codimension is at least two. \endproclaim \demo {Proof of the Corollary} Topological transitivity, the invariance of $A_\Bbb Z (B)$, and the openness of $B$ imply that $\text {\rm Int} A_\Bbb Z (B) \neq \emptyset$. Proposition 3.3 then proves the claim. \enddemo \qed \demo {Proof of Theorem 4.1} Throughout the whole paper we will denote by $\{\gamma^s\}$ and $\{\gamma^u\}$ the invariant foliations defined by the dynamics in question, and by $\gamma^s_{\varepsilon}(x)$ and $ \gamma^u_{\varepsilon}(x)$ the local invariant manifolds of size $\varepsilon$ through the point $x$. Denote by $\Cal P$ the set of periodic points of $\bom \setminus F$. We use the following simple statements: \noindent {\it Claim 1.} $\Cal P$ is dense in $\bom$. \noindent {\it Claim 2.} If $x \in \Cal P$, then $\gamma^u(x) \cap F = \gamma^s(x) \cap F = \emptyset$. These claims easily provide the truth of the Theorem. Indeed, let $y \in F$ and choose $\varepsilon > 0$ small. The foliations $\{\gamma^u\}$, $\{\gamma^s\}$ define a local product structure and using it we can consider a parallelogram $\gamma^u_\varepsilon (y) \times \gamma^s_\varepsilon (y)$. Moreover, we define $ F_0 = F \cap (\gamma^u_\varepsilon(y) \times \gamma^s_\varepsilon (y))$. By Claim 2, for any $x \in \Cal P$, $(\gamma^u(x) \cup \gamma^s(x)) \cap F = \emptyset$, and, consequently, $F_0 \subset (\gamma^u_\varepsilon (y) \setminus \cup_{x \in \Cal P}\gamma^s(x)) \times (\gamma^s_\varepsilon (y) \setminus \cup_{x \in \Cal P}\gamma^u(x))$. Claim 1 and Proposition 3.3 then say that the factors of the previous product set have codimension at least one each. Hence the Theorem follows by the product theorem (cf. Theorem III.4 of [H-W(1941)]). Let us now prove Claim 1. Take an arbitrary open subset $G$ of $\bom$. The open set $G \setminus F$ is not empty for otherwise we would have $\dim F = n$. Since $\Cal P$ was dense in $\bom \setminus F$, we also have $(G \setminus F) \cap \Cal P \neq \emptyset$. Turn next to Claim 2. We prove $\gamma^s(x) \cap F = \emptyset$ for an arbitrary $x \in \Cal P$. Assume $T^px =x$. Select an open neighbourhood $G$ of $x$ disjoint from $F$. By invariance, $(\cup_{n \in \Bbb Z} T^n G) \cap F = \emptyset$. Now for any $y \in \gamma^s(x)$\ \ $\rho(T^{kp}y, x) \to 0$ if $k \to \infty$, and thus, for $k$ sufficiently large, $T^{kp}y \in G$ implying $y \notin F $. \enddemo \qed \noindent {\bf Remark 4.2.} After the aforementioned result, the study of compact invariant subsets was continued --- among others by Franks [F(1977)], Hancock [H(1978)] and Ma\~n\'e [M(1978)]. Since the sets $A_\br(B)$ provide natural examples of compact, invariant subsets --- in fact, all compact invariant subsets are of this form ---, this description has been used by several authors. In particular, for every $0 \le k \le d-2$, Przytycki [P(1980)] found examples of sets $B_k$ such that $\dim A_\br(B_k) = k$. \heading 5. A Strong Ball-Avoiding Theorem for Hyperbolic Systems (With or Without Singularities) \endheading \bigskip \bigskip For simplicity, we formulate the theorem for discrete time groups $\ddina$ of hyperbolic systems since the generalization to continuous time is straightforward. Our setup is that $\bom$ is a compact $C^\infty$-manifold and $\mu$ is a smooth, invariant probability measure. We also want to permit singularities as it is done in [L-W(1995)] or in [Y(1998)] or in [Ch(1998)]. For saving space, we do not list the conditions formulated in these works since we only use some standard consequences of them. Namely: the $\mu$-a. e. existence of the local invariant manifolds and the absolute continuity of the canonical isomorphism between them, and further the simple fact that if in case of singularities we define trajectory branches as it is described, for instance, in????, then can always be considered continuous on these trajectory branches. On the other hand, the kind of hyperbolicity needed will be implicitly ensured by our assumptions. Start with the corresponding definition. \proclaim {Definition 5.1} A point $x \in \bom$ is called {\sl a zigzag point} if one can find arbitrary small open neighbourhoods $U$ of $x$ such that for every zero-set $A \subset \bom$ there exists another zero-set $A'\supset A$ with the property: for every $y, y' \in U \setminus A'$ there exists a chain (also called Hopf-chain) $$ \g_{\text {loc}}^u(z_0), \g_{\text {loc}}^s(z_1), \g_{\text {loc}}^u(z_1), \g_{\text {loc}}^s(z_2), \dots, \g_{\text {loc}}^u(z_{n-1}), \g_{\text {loc}}^s(z_n) $$ (here $z_0=y, z_n=y'$) of local unstable and stable invariant manifolds inside $U$ such that each intersection $$ \g_{\text {loc}}^u(z_i)\cap \g_{\text {loc}}^s(z_{i+1}) \qquad \qquad \qquad (i=0, \dots, n-1) $$ and $$ \g_{\text {loc}}^s(z_i)\cap \g_{\text {loc}}^u(z_i) =\{z_i\} \qquad \qquad \qquad (i=1, \dots, n-1) $$ consists of exactly one point belonging to $U\setminus A'$. \endproclaim The following theorem generalizes Lemma 4.3 of \kssw, and its proof is also based on its ideas. \proclaim {Theorem 5.2} Assume that \roster \item "{(i)}" the group $\ddina$ is mixing; \item "{(ii)}" for the subset $Z$ of zigzag points of $\bom$, $\bom \setminus Z$ is slim; \item "{(iii)}" $B\neq \emptyset\ (\subset \bom)$ is open; \item "{(iv)}" $H\ (\subset \bz)$ satisfies\ $ \sup H = -\inf H = \infty.$ \endroster Then $A_H(B)\ (\subset \bom)$ is a closed zero-set of codimension at least two. \endproclaim \noindent {\bf Remark 5.3.} For the first glance, condition (ii) of Theorem 5.2, as formulated, might seem too restrictive, but, fortunately, this is not the case.

The present study employs the life history method, which is a collaborative venture between the researchers and four Informants, to tell the stories of the beginning teachers' role management action within theories of context. Informed by literature on teacher professionalization and professional socialization, we found that two first year teachers were caught In a tension of external performance-oriented appraisal and internal appraisal of self-worth. Another two beginners in their second year of teaching faced a tension of defining their professional self-identity when they were obliged to work against the grain in terms of making their pedagogical decisions. These beginners employed role management strategies ranging from situational adjustment to strategic redefinition to cope with the tension. The strategies were found to have different Impact on the their development as a teaching professional. When these role management strategies were analysed in the beginners' biographical, the schools' structural and the wider socio-historical contexts, we have better understanding of the conditions which contribute to the beginning teachers' employment of role management strategies that are conducive to desirable professional development.

High Flying Bugs
Have you ever wondered what altitude insects reach when flying in the sky? Although there is much to be learned about insect physiology and how it handles high altitudes, scientists have developed a few techniques that help determine the height that certain insects can reach.
By putting bumblebees into a chamber that mimics high altitudes researchers found that bumblebees can reach altitudes as high a mount everest, which is almost 30,000 feet. This is an impressive height when you consider that the highest flying bird reaches 37,000 feet. Flies and butterflies can even reach heights of just under 20,000 feet.
However, higher altitudes means thinner air, and that means that flying insects will have to flap their wings much faster since the small amount of molecules in the air make it harder for wings to take advantage of lift. But the bumblebees will change the way they flap their wings to adapt to the change in oxygen. By studying the way insects fly at high altitudes we can learn more about engineering mechanisms of human flight.
Do you think that learning about how insects fly at extremely high altitudes could help humans develop more sophisticated airborne vehicles?

Events to highlight benefits of trees on farms
How can trees increase your farm's income? Find out at two free events this May.
Soil Association Scotland is teaming up with with practical farmer and Nuffield Scholar Stephen Briggs of Abacus Organic, and experts from Forestry Commission Scotland and the Woodland Trust for these practical events.
The two 'Trees: a crop with multiple benefits' events will examine managing and planting trees for improved livestock and arable production. Both events will cover the same fundamentals, but will involve visits to different farms, each with a different emphasis.
The first, on Thursday 26 May in Aberfeldy, Perthshire, includes a visit to Bolfracks Estate, with a look at a long-established grazing system that integrates trees. The second event on Friday 27 May in Newburgh, Fife includes a visit to Parkhill Farm, with a look at the farmer's plans to establish alleyway planting of apple trees in arable fields to increase production along with planting native trees to provide shelter for livestock.
Lyn White, Agricultural Development Manager for Soil Association Scotland said:
"We want to spread the word: trees have real potential to help farmers, growers and crofters in Scotland. They can be good for land, good for crops, good for livestock and ultimately good for business, and these events show exactly how.
"We've pulled together top experts and experienced farmers to give attendees a practical look at everything about farming with trees: from how to access funding, where to start with planning, how trees can benefit your farm, a look at real-life farms that are working with trees, and lots of time for questions and discussion. Best of all – these events are free for all land managers."
These events are open to all farmers, organic or otherwise, and are free of charge to farmers and land managers (or £40.00 plus VAT to any other interested parties). Booking is essential. For further information visit _URL_ call Lyn White on 07899 791748 or email _EMAIL_.
These events are part of Soil Association Scotland's Future Farming Scotland programme, funded by the Scottish Government and the European Agricultural Fund for Rural Development with partner funding from Quality Meat Scotland, Forestry Commission Scotland, Innovative Farmers and The Prince of Wales's Charitable Foundation.

Towards an EU import ban on forced labour: new study
The European Parliament has called for a new EU instrument that allows for import bans on products related to severe human rights violations such as forced labour or child labour. This tool could be a complementary measure to the EU legislation on corporate human rights and environmental due diligence along supply chains which is currently being developed. The landmark due diligence law is expected to introduce requirements for all companies operating in the EU to take steps to prevent and address human rights and environmental harm along their value chains. The law should also give victims possibility to bring companies to court in Europe when harm occurs. However, certain products stemming from severe human rights violations should not enter the EU market at all. Therefore, in addition to this upcoming due diligence law which is focused on company behaviour, a related instrument that focuses on products is needed, allowing for restrictions or bans.
In this paper, we examine different options for an EU mechanism. In particular, we consider whether the import bans could be introduced via:
 - o EU foreign policy, i.e. the new EU Human Rights Sanctions mechanism
 - o amending our Free Trade Agreements and other trade mechanisms
 - o a new Internal Market instrument
 - o a new instrument with a trade legal basis
A brief examination of each option's pros and cons leads to the conclusion that a new EU instrument with a trade legal basis would be preferred. Such instrument could draw heavily on previous instruments such as the Regulation protecting intellectual property rights. A deeper evaluation and analysis of what works well and what doesn't (e.g. the absence of remediation required) in the US Tariff Act can lead to more detailed options for an EU approach.
The import ban instrument would be a complementary measure to the upcoming EU due diligence law, giving the EU an additional tool to guarantee that no products being sold in the EU are tainted with grave human rights abuses. It would allow us to immediately stop goods at our borders when we have reasonable suspicion that they are made with forced labour. The onus would then be on the company in question to prove that this is not the case, or to take action to remedy the situation on the ground before these products are allowed in again.
Experience from the US shows that such bans can be extremely effective and lead quickly to remedy for workers. However, we need to learn from the lessons of the US approach regarding the things that have not worked so well: we need do it in a more transparent, remedy-centred way, that focuses on the impacts for people, and is not a hidden protectionist tool. Conditionality for the lifting of bans or easing of restrictions should always be that companies take measure to improve the situation on the ground; in this regard the remediation of victims should always be prioritized. The instrument needs to be therefore carefully designed and applied.

Making Homelessness Applications for Single Refugees
When receiving leave to remain, refugees commonly become homeless.
With demand for housing high, it can be difficult to prove that individuals have a priority need for accommodation. Yet many single refugees suffer from mental and physical health conditions that make them more vulnerable. If this vulnerability is exacerbated by being homeless, councils may have a duty to house them.
Providing an overview of how to support single refugees through a homelessness application, the training will include:
- Understanding what duties councils have towards homeless applicants
- How to support refugees to make a homelessness application
- When and how to challenge homelessness decisions

Another dinosaur (not 'Obamadon gracilis') / AFP/Getty Images
Babies and pets have been named in honor of President Obama -- and now a prehistoric lizard
Researchers at Yale University have dubbed a newly discovered species of dinosaur -- a lizard -- Obamadon gracilis, citing the president's broad smile, Reuters reports.
In modified Latin, Obamadon stands for "Obama's teeth," while gracilis means "slender."
"The lizard has these very tall, straight teeth and Obama has these tall, straight incisors and a great smile," said Nick Longrich, a paleontologist at Yale.
Also reports Reuters:
"Like many other dinosaurs, the lizard died out about 65 million years ago when a giant asteroid struck earth, scientists say.
"Longrich said he waited until after the recent U.S. election to name the dinosaur.
"'It would look like we were kicking him when he's down if he lost and we named this extinct lizard after him,' he said in an interview....
"Other celebrity names also have been used to name new species. A small Caribbean crustacean has been named after reggae icon Bob Marley, an Australian horsefly has been named in honor of hip-hop star Beyonce, and an endangered species of marsh rabbit has been named after Playboy magazine founder Hugh Hefner."

The Jackson deserialize and cast to Integer all numbers if value in range of Integers instead it cast to Long. I would like to cast ALL values to Long. Is it exist easy solution of issue?
share|improve this question
possible duplicate of Forcing Jackson to deserialize to specific primitive type – Fabian Lange Jul 22 at 19:35
1 Answer 1
Jackson deserializes to type you tell it to, so if you declare property to be of type long or Long it would construct it as long. But maybe you are binding to "untyped" structure like Map? If all values are of type Long, you could just declare type appropriately, like:
Map map = objectMapper.readValue(json, new TypeReference>() { });
Alternatively might be able to add custom Deserializer for Object.class with different handling (default deserializer is org.codehaus.jackson.map.deser.UntypedObjectDeserializer).
It might help if I knew what you are actually trying to do -- Integer and Long are both numbers, so often distinction does not matter a lot... so what is the reason to require Longs?
share|improve this answer
The deserialized numbers are IDs of objects that I would like to retrieved through the Hibernate. When I use Integer it throw an exception that it can convert from integer to long. – eugenn Jun 30 '10 at 13:14
Then the easiest way might be to explicitly just convert these, something like 'Long id = numberValue.longValue();'. Unless if map only has numeric values, in which you can declare types as Map (as I mentioned above) – StaxMan Jul 1 '10 at 7:06
_USER_ explicit conversion will become redundant when the IDs become long so wouldn't some form of type casting (e.g. JsonTypeInfo) be preferable? – ajostergaard Aug 24 '13 at 7:02
Jackson does type co(nv)ercions where necessary. So if POJO indicated that long or Long are needed, that's what you'd get. The original post is vague enough that I don't really know enough to know what the right answer is. But polymorphic type inclusion does not seem to be part of the picture. – StaxMan Aug 27 '13 at 17:43

What is octal latch? - Definition from WhatIs.com
Part of the Microprocessors glossary:
An octal latch is an integrated circuit (IC) that contains eight binary digital circuits called latches. A latch is a form of sequential logic circuit.
A simple latch has two stable logic states. The latch maintains its states indefinitely until an input pulse called a trigger is received. If a trigger is received, the latch outputs change states according to defined rules, and remain in those states until another trigger is received. Latches can be interconnected to form more sophisticated circuits that function in memory chips and microprocessors.
An octal latch can hold onto the data at its inputs before transmitting the data to its outputs. This ability is useful in applications where a number of devices share a single data bus, because it allows the processor to store data, go onto other operations that require the bus, and return to the stored data later if the need arises.
A common example of an octal latch is the Fairchild LVX573, an advanced high speed CMOS IC with eight three-state outputs. When the output enable input is high, the eight outputs are in a high-impedance condition.

What is the purpose of obligatory and optional properties of the objects?
For each class, WinRunner learns a set of default properties. Each default property is classified obligatory or optional.
 > An obligatory property is always learned (if it exists).
 > An optional property is used only if the obligatory properties do not provide unique identification of an object. These optional properties are stored in a list. WinRunner selects the minimum number of properties from this list that are necessary to identify the object. It begins with the first property in the list, and continues, if necessary, to add properties to the description until it obtains unique identification for the object.

CGRect frame = CGRectMake(0.0f, 0.0f, 100.0f, 30.0f);
What's the difference between the following two code snippets?
 UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
 button.frame = frame;
 UIButton *button = [[[UIButton alloc] initWithFrame:frame] autorelease];

I think they're equivalent. Haha! Trick question you sneaky little punk!
 1. -buttonWithType: returns an autoreleased UIButton object.
 2. +[NSObject alloc] defaults scalar instance variables to 0, so buttonType should be 0, or UIButtonTypeCustom.
Pros & Cons
 1. You could argue that it's clearer to use -buttonWithType: and set buttonType explicitly and that it's safer in case Apple changes UIButtonTypeCustom to be 1 instead of 0 (which will most certainly never happen).
 2. On the other hand, you could also argue that it's clear & safe enough to use -initWithFrame. Plus, many of the Xcode sample projects, such as "TheElements" & "BubbleLevel," use this approach. One advantage is that you can explicitly release the UIButton before the run loop for your application's main thread has drained its autorelease pool. And, that's why I prefer option 2.

+1 for internal dialog. – glenstorey Aug 22 '12 at 17:54
"-[NSObject init] defaults scalar instance variables to 0" No, it's actually +alloc that sets instance variables to 0. "so buttonType should be 0" No, this depends on what -[UIButton init] (if there is such a method) does. Sure, it might currently set it to 0 or doesn't set it (in which case it would be 0); but since that method it not documented, they could change its behavior in the future. You have no guarantees on what it does. – user102008 Aug 27 '12 at 21:06
I know this is old but I have noticed you have to use [UIButton buttonWithType:] are your button type never gets set. Also you've written -buttonWithType as an instance method it should be a class method so you need to replace - with +. – Popeye Mar 28 '13 at 15:57

I would strongly suggest using the first approach (+buttonWithType), because that's the only way to specify the button type.
If you +alloc and -initWithFrame:, the buttonType is set to some standard value (not sure which, and this could change in later versions of the SDK) and you can't change the type afterwards because the buttonType property is read only.

The main (maybe the only) difference is in memory management: as you said, buttonWithType returns an autoreleased UIButton. This way you don't have to worry about releasing it. On the other hand, you don't own it, so you cannot release it when you want to (except, of course, if you drain the autorelease pool).
Calling explicitly [[UIButton alloc] initWithFrame:frame], instead, you dynamically alloc your button, so you own it and you're responsible for releasing it.
If you plan to retain your button for some reason then maybe you should consider the second solution, but if, as in this case, you are autoreleasing it immediately, there's no big difference between the two way of creating a button...

Two options are the same but I prefer option 2 because it can handle memory management

You can use the first and do "[button retain];", so you will never lose the pointer.

The National History Bee is a buzzer-based history quiz competition for individual students. Please see below for a comprehensive account of how the Bee works. If you have any further questions, please email our International Director, Mrs. Nolwenn Léon Madden
In order to compete in the History Bee, you must be 18 years or younger at the time of your Regional Bee. If you turn 19 before the National Championships, that's okay. You must also be enrolled in a high school or younger school or a comparable secondary school that corresponds to an American high school in terms of the age range served (i.e. no schools that are comparable to universities).
In order to compete in the Junior Varsity Division of the History Bee, you must be 16 years or younger at the time of the Regional Bee. If you are in an American high school, or an institution that follows a comparable age division, you cannot be in the upper two years (i.e. above tenth grade) even if you are 16 or younger. If in doubt, ask the Tournament Coordinator or Tournament Director for your tournament, or better yet, contact the Tournament Coordinator in advance.
There is no younger age limit – a brilliant and well-behaved 8 year-old is welcome to compete. Likewise, there is no limit on types of schools – local, international, public, private, religious, American schools abroad, etc. are all welcome. Students from the 50 US states may compete if they have not competed yet this year, but then forfeit their eligibility for any other tournaments in the USA.
Students are only allowed to compete at one Regional Bee in Asia this year.
At all History Bees, there are three preliminary rounds of 30 questions each. In each round, you'll be in a room with 5-10 students. Usually, it's 6 or 7. Depending on how many students are competing (see below under "Final Round Structure" for a full explanation) the 2, 5, or 10 highest scorers from the preliminary rounds in both the Varsity division and the Junior Varsity division, then compete in the final rounds. The Junior Varsity and Varsity divisions are kept entirely separate – there is no crossover, including in the final rounds. Each round takes about 20-30 minutes to complete, including the finals.
In a History Bee round, we feature thirty tossup questions. Students each have a buzzer and attempt to be the first student to ring in and answer correctly. Students may ring in at any point in the question – they are encouraged to interrupt the moderator to do so. After they ring in, they give their answer. If they are correct, they get a point. If incorrect, they cannot buzz again on the question. Three incorrect answers given will end the question, at which point the moderator reveals the answer. They do not normally lose a point if they are incorrect except if they are the third student to answer incorrectly before the end of the question, in which case, they do lose a point (so it is possible, conceivably to have a negative score). If the question has been read to completion, three incorrect answers will still end the question, but no penalty will be assessed.
Once a student has reached 8 points, that student is done for that round. But, students receive bonus points based on how early they reach 8 points. The following table summarizes the bonus structure:
Reaching 8 pts on or before question… Results in this many bonus pts… And thus this many total pts…
Twelve Five Thirteen
Fifteen Four Twelve
Twenty Three Eleven
Twenty-Five Two Ten
Thirty One Nine
Since there are 30 questions in a round, it is thus impossible to finish the round with a score of eight points exactly.
Students are grouped into different groups for each of the three rounds. For the 2012-2013 school year, questions can reference all eras and places in history throughout each round. After all three rounds, the scores from all rounds are added up, and the top students advance to the finals.
Final Round Structure
In the final round, the top two, five or ten students in both the Varsity and Junior Varsity Divisions all compete at once. If starting with ten, they seek to then be among the first five students to reach three points. Then, the scores reset to zero, and the five remaining students seek to be among the first two students to reach four points. Finally, the scores reset to zero again, and the remaining two students seek to be the first to reach five points. Whether we take two, five, or ten students into the finals will be announced at the start of the Bee – it depends on how many teams attend, and how many students compete in each division. A field needs at least 12 students to take the top five into the final, and a field needs at least 25 students to take the top 10 into the final. If both the Varsity and Junior Varsity Divisions have over 25 competing students, we will take ten from the Varsity division and five from the Junior Varsity.
In the History Bowl, there are a number of different question styles. In the Bee, by contrast, all questions are "pyramidal" tossups, where we start with more obscure information and move to more familiar information. Questions cover the history of the arts, sciences, religion, philosophy, languages, historical geography, recent history and the history of sports and entertainment in addition to the usual social, political, and military history. In the final rounds, the questions are, on average, slightly longer and more difficult. Here are a few examples of preliminary and finals questions:
Sample Preliminary Questions
The northern tip of this island was home to this nation's Jaffna kingdom, which ruled at the same time as other empires on this modern country like the Kotte Kingdom and the Kandy Kingdom. For the point, name this Asian island nation, the site of the Tamil Tigers separatist movement, which was once known as Ceylon.
ANSWER: Sri Lanka [or Ceylon before mentioned]
It was announced in a graduation speech given at Harvard University and designed in part by William Clayton, George Kennan, and a Secretary of State. For the point, name this American economic plan that intended to halt the spread of Communism by providing financial support to European nations, which was conducted under Harry S. Truman.
ANSWER: Marshall Plan or European Recovery Plan or ERP
Sample Finals Questions
This leader's accomplishments include putting down Nayan's rebellion and installing Wonjong as the ruler of the Goryeo dynasty of Korea. Three times, he attempted to invade Vietnam along with his brother Mongke, and his two attempts to invade Japan were both cut short by severe typhoons known as kamikaze. He employed Marco Polo and his father as ambassadors. For 10 points, name this founder of the Yuan Dynasty, a grandson of Genghis Khan.
ANSWER: Kublai Khan
This navy sent an expedition to Mexico on the San Buena Ventura, a ship built by William Adams. This navy was instructed to only allow passage to ships abiding by the Red Seal system. This navy was crushed by Admiral Yi Sun-sin and his turtle ships during an abortive invasion of Korea. For 10 points, name this navy that was led by Admiral Yamamoto during World War II.
ANSWER: Japanese Navy [accept Tokogawa navy until "Yamamoto"]

Watershed Management
Redmond City Council approved the Citywide Watershed Management Plan on December 3rd, 2013. The primary goal of the plan is to focus resources and efforts into specific watersheds (5 total) to recover in-stream habitat within decades. This will include capital investment planning, design, and construction, in addition to programmatic efforts.
2013 Redmond Watershed Management Plan – Final
Washington Department of Ecology has approved Redmond's Citywide Watershed Management Plan as an alternative approach to stormwater management minimum requirements detailed in NPDES Municipal Stormwater Permit.
Washington State Department of Ecology Approval Letter
Using a watershed approach to achieve healthy aquatic habitat has been a long-standing policy detailed in the City of Redmond Comprehensive Plan and is recognized by stormwater and surface water restoration practitioners as the recommended approach to accommodate healthy streams in an urbanized landscape.
The stormwater utility is now in the process of implementing the plan. This includes developing transparent tracking systems, detailed engineered implementation plans for select watersheds, effectiveness monitoring development, and regional collaboration on this approach.

What is a watershed?
What is a Watershed
A watershed is an area of land -- regardless of size -- where snowmelt and rainwater drain from higher areas into lower lying areas and then into a single water body; such as a wetland, stream, river, lake or ocean. Watersheds are separated from each other by elevated features such as ridge tops, hills, or roads.
When precipitation increases rapidly and surface water flows across flat or impervious areas, it can cross over watershed boundaries. For example, if the upper Sammamish River Valley experienced a 100-year storm, stormwater runoff would most likely flow across the boundaries of the City's smaller watersheds and flood areas of the Sammamish Valley floor.
Interesting Facts About Redmond's Watersheds
 - The City of Redmond has designated approximately 87 different watersheds, either wholly or partly included within city limits.
 - The smallest of these watersheds is 1.6 acres; the largest is 1,685 acres.
 - The majority of the city watersheds (approximately 66) occupy less than 200 acres; another 13 occupy between 200-400 acres; and only eight watersheds are larger than 400 acres in size.
 - Total Impervious Surface (TIS) as a percentage of total watershed area, varies among these watersheds from a low of 2% to a high of 89%.
 - Only two of the 87 watersheds have less than 10% TIS. Twenty-seven watersheds have 10-40% TIS; and the remaining 58 watersheds have impervious surfaces exceeding 40%.
(Large-scale land cover data is available for all of Redmond's watersheds on King County's website: King County Land Cover 2001)
Why Focus on Watershed Management?
What is a Watershed
In the past, project development and land management decisions have often been approved project-by-project, jurisdiction-by-jurisdiction and regulation-by-regulation. This singular approach does not identify the significant cumulative impacts to watershed functions and processes when viewed as small, seemingly harmless, projects.
What happens when, instead, you look at things from a watershed perspective? Because so many watershed functions and processes are closely interrelated, it becomes harder to look at a single project or management issue in isolation. Landscape linkages become more obvious and several issues can be dealt with together--cumulative impacts to a wider area become clearer and may be addressed in a more equitable and cost efficient manner.
Adopting a broader watershed perspective encourages the development of solutions to environmental issues that can satisfy several regulatory requirements simultaneously. For example, compliance with the Clean Water Act, Endangered Species Act, or possible hazardous waste and toxics cleanup. Watershed plans will also enable us to make better choices about how to plan, maintain, and construct our drainage systems so they can better meet the community's many needs.
Watershed management solutions can only be effective with support from policymakers, elected officials, and the public. These groups are encouraged to adopt a long-term, broad-based watershed perspective.
What does stormwater have to do with watersheds?
What is a Watershed
As urban areas grow, we dramatically alter the way water flows through developed areas. As natural vegetation is replaced with impervious surfaces (roads, parking lots, buildings, and rooftops), runoff from rainfall increases, flushing sediment and pollutants into nearby wetlands, streams, and lakes. This in turn impacts our surface water quality--one of the toughest environmental challenges facing all cities. Redmond has adopted a watershed management approach to address these environmental challenges.
Using the watershed as our vantage point, we can craft better stormwater management techniques and meet the needs of businesses, residents, and wildlife.
What watersheds does Redmond manage?
What is a Watershed
Historically the US Geological Survey, Washington Department of Ecology, and King County have monitored the larger main-stem rivers and streams in Redmond (Sammamish River, Bear and Evans Creeks), as well as Lake Sammamish. When Redmond started its water quality monitoring program in 1995, it focused on the smaller streams and watersheds that drain into these larger water bodies.
Redmond's Watershed Map
What is a Watershed
Watershed Map
The Watershed Map provided above identifies the 20 watersheds, and associated water bodies, within Redmond's city limits. Each watershed is color coded based on the strategy needed to restore a healthy water body in each watershed. Green color coded watersheds are in good shape, yellow watersheds are the most likely to become healthy with investment (programs and projects), orange watersheds are likely to become healthy with investment over a longer period of time, and red watersheds are heavily impacted and will take substantial time and investment to become healthy. No water body will be allowed to get worst, but improvements to existing impacts will be focused as much as possible in the yellow color coded watersheds.

Dye localization is a useful method for the resection of unidentifiable small pulmonary lesions. This study compares the transbronchial route with augmented fluoroscopic bronchoscopy (AFB) and conventional transthoracic CT-guided methods for preoperative dye localization in thoracoscopic surgery.
Between April 2015 and March 2019, a total of 231 patients with small pulmonary lesions who received preoperative dye localization via AFB or percutaneous CT-guided technique were enrolled in the study. A propensity-matched analysis, incorporating preoperative variables, was used to compare localization and surgical outcomes between the two groups.
After matching, a total of 90 patients in the AFB group (N = 30) and CT-guided group (N = 60) were selected for analysis. No significant difference was noted in the demographic data between both the groups. Dye localization was successfully performed in 29 patients (96.7%) and 57 patients (95%) with AFB and CT-guided method, respectively. The localization duration (24.1 ± 8.3 vs. 21.4 ± 12.5 min, p = 0.297) and equivalent dose of radiation exposure (3.1 ± 1.5 vs. 2.5 ± 2.0 mSv, p = 0.130) were comparable in both the groups. No major procedure-related complications occurred in either group; however, a higher rate of pneumothorax (0 vs. 16.7%, p = 0.029) and focal intrapulmonary hemorrhage (3.3 vs. 26.7%, p = 0.008) was noted in the CT-guided group.
AFB dye marking is an effective alternative for the preoperative localization of small pulmonary lesions, with a lower risk of procedure-related complications than the conventional CT-guided method.

Testing-Based Forward Model Selection
AbstractThis paper defines and studies a variable selection procedure called Testing-Based Forward Model Selection. The procedure inductively selects covariates which increase predictive accuracy into a working statistical regression model until a stopping criterion is met. The stopping criteria and selection criteria are defined using statistical hypothesis tests. The paper explicitly describes a testing procedure in the context of high-dimensional linear regression with heteroskedastic disturbances. Finally, a simulation study examines finite sample performance of the proposed procedure and shows that it behaves favorably in high-dimensional sparse settings in terms of prediction error and size of selected model.

CBeebies launches a mindfulness app for kids voiced by Stephen Fry - here's how to download it
Friday, 8th May 2020, 3:30 pm
Updated Friday, 8th May 2020, 3:30 pm
CBeebies has released a new mindfulness app activity voiced by Stephen Fry to help children during lockdown
The app experience, called Your Mindful Garden, aims to teach children between 0 - 6 years old, how to develop mindful habits.
It's aimed at helping them through difficult and unexpected times such as the coronavirus pandemic.
The new app activity comes after the BBC expanded their education website BBC Bitesize, to help children learn during lockdown.
What activities are included in the app?
According to the CBeebies website, Your Mindful Garden provides three activities to complete daily, which aim to increase "focus, creativity and calm" in children.
"Your Mindful Garden teaches valuable techniques to help children de-stress and unwind - useful skills both in these tough times and for later in life," reads a statement on its website.
In-app hide and seek with CBeebies characters is one example of the concentration based activities, while some creative activities include raking patterns in a zen garden.
Creative and concentration based activities "help to clear and relax the mind", according to the children's television channel.
The third and final activity is always geared towards calming the child. This can range from physical activities such as stretches to breathing exercises.
"From learning to stretch with a new monkey friend to breathing along with a frog, it's all about learning valuable techniques that can help improve children's wellbeing," the website says.
Why is it called Your Mindful Garden?
The app activity gets its name from one of its core components. Your Mindful Garden asks children to virtually dig a hole in the app to plant a mindfulness tree.
Once they have completed a full set of three daily activities, they are rewarded with an in-app surprise element which is added to their tree.
Stephen Fry, who voices the app experience said: "It was such a pleasure to be involved with a simple, but beautifully designed idea like this. I hope and believe that many children will find the game fun, engaging and helpful in their journeys through life."
How can I get the app?
Your mindful Garden which was developed with the help of a professional mindfulness consultant, is now available for free in the CBeebies Go Explore app, which itself can be downloaded from the App Store, Google Play or Amazon App Stores.

Laetitia and her group crossed the state line into West Virginia. Their ultimate destination was Capon Bridge, but first they went south for a stop at Capon Springs. One meaning of the word "capon" is a male chicken whose testicles have been surgically removed to maximize meat production in the castrated bird. Development of the technique is credited to the Romans. However the West Virginia place name is derived from the Shawnee Indian word for a local stream, "Cape-cape-de-hon," meaning "River of Medicine Water."
Originally called Frye's Springs, the river was believed to have medicinal properties. During the mid-nineteenth century, a hotel, spa, and resort, the Capon Springs Historic Hotel, was built to capitalize on the springs putative healing capability. Laetitia brought her group to the hotel, where they toured the grounds. Some of the group used the spa.
Then they headed north to the Edwards Run Wildlife Management Area for some wildlife viewing before heading toward Capon Bridge for the evening. On the way they stopped at the late-nineteenth-century Hook Tavern. When the group viewed the span over the Cocapon River for which Capon Bridge is named, a poultry farmer from Kentucky named Clem who was on the tour said to his wife, "See, I told you the bridge wasn't actually made out of capons." Laetitia smiled and later wrote the limerick of the day.
Clem thought Capon Bridge must be schlock
When he thought of his own capon flock
For a castrated bird
Is rather absurd
For use as a bridge building-block.
