The Consortium for Wildlife Bycatch Reduction conducts research to understand the nature of interactions between endangered non-target species and fishing operations.
Short-finned Pilot Whales and False Killer Whales
Duke University scientists have been working with longline fishermen within the Cape Hatteras Special Research Area (CHSRA) to study pilot whale (Globicephala spp.) interactions with the longline fishery. Their initial findings were that short-finned pilot whales (Globicephala macrorhynchus) are the main species that interact with longline vessels during the fall season, that interactions within this fishery occur frequently and most often occur during the evening through the early morning, and that there is substantial depredation of tuna (target species) by pilot whales.
Researchers at Duke are currently trying to quantify the extent of pilot whale depredation on tuna off North Carolina and to determine the proportion of the population that engages in depredation. They are examining the relative importance of tuna in the diet of pilot whales in the CHSRA using stable isotope analysis.
Both short-finned pilot whales and false killer whales (Pseudorca crassidens) can be hooked by pelagic longline gear. Researchers at Duke University and the University of North Carolina are assessing the "hook pulling" jaw strength of pilot whales and false killer whales to provide biological guidance for "whale-safe" hooks by understanding the thresholds of hook bending capacity of the jaws of these odontocetes. The target bending threshold strength is determined by the minimum required to retain the target catch. Owing to the large disparity in weight between an average or large-bodied target fish (e.g. yellowfin tuna) and that of pilot or killer whales, reducing hook strength to this threshold should result in retention of target catch while mouth-hooked whales should be able to pull on the hook, straighten it, and de-hook themselves.
Bottlenose dolphins (Tursiops truncatus) are known to remove captured fish (depredate) from gillnets set for Spanish mackerel in North Carolina; this behavior increases the dolphins' risk of entanglement. Danielle Waples, at Duke University, conducted a field evaluation of SaveWave acoustic deterrent devices on these gillnets. She recorded interactions between dolphins and Spanish mackerel gillnets equipped with the devices and found that dolphins were less likely to approach or interact with nets that had active SaveWave devices, but their presence did not eliminate interactions completely. She also found that dolphins were echolocating more when active SaveWave devices were present. This may mean that the dolphins used echolocation to invistigate the nets with SaveWave devices, which may improve their ability to detect and avoid the nets.
Loggerhead Sea Turtles
Bottom-set gillnet fisheries that target flounder in the Pamlico Sound, North Carolina are responsible for incidentally taking juvenile sea turtles during the fall months. This is especially problematic given that it is the State's most valuable finfish fishery. The Division of Marine Fisheries has employed a variety of management tools to address this problem including: closed areas, mandatory permits, reporting and observer coverage, gear restrictions, net attendance, goals for reduced strandings, and incidental take limits. In 2002, the National Marine Fisheries Service was forced to permanently close the deepwater portion of the fishery due to sea turtle takes. Shallow water areas remain open, with portions closed seasonally when takes exceed certain levels.
Catherine McClellan, while at Duke University, tracked loggerhead sea turtles, Caretta caretta, using satellite telemetry to determine how their movements interacted with the inshore large-mesh gillnet fishery. In Pamlico Sound, loggerheads spent 64 to 70 percent of their time in the deep water areas that are closed to gillnet fishing.

Single-Acting Hydraulic Cylinder (Simple)
Basic functionality of single-acting hydraulic cylinder
The Single-Acting Hydraulic Cylinder (Simple) block represents a simplified version of a hydraulic cylinder, developed for applications where only the basic cylinder functionality must be reproduced, in exchange for better numerical efficiency. For these reasons, such factors as fluid compressibility, friction, and leakages are assumed to be negligible. The hard stops are assumed to be fully inelastic, to eliminate any possible oscillations at the end of the stroke. The model is especially suitable for real-time and HIL (hardware-in-the-loop) simulation, if such simplifications are acceptable.
The model is described with the following equations:
|F||Force developed by the cylinder|
|v||Cylinder rod velocity|
|vR,vC||Absolute velocities of cylinder rod and cylinder case, respectively|
|p||Pressure at the cylinder inlet|
|q||Flow rate at the cylinder inlet|
|x0||Initial distance between piston and the cap|
|Fc||Hard stop force|
|xE||Distance the piston can travel to fully extend from initial position|
|xR||Distance the piston can travel to fully retract from initial position|
The main difference between this block and the Single-Acting Hydraulic Cylinder block is the representation of the hard stop:
The Single-Acting Hydraulic Cylinder block utilizes the elastic model of the stop, which is essentially a combination of a spring and a damper, connected in parallel. The stiffness of the spring, which represents contact stiffness of colliding bodies, is very high, resulting in high-frequency, low-magnitude oscillations at the moment the bodies collide. These oscillations can hardly be noticed experimentally, but they are difficult to process by a numerical simulation and generally decrease numerical efficiency.
The hard stop in the Single-Acting Hydraulic Cylinder (Simple) block is represented with the inelastic model, which is essentially a viscous damper with the penetration-dependent damping coefficient. This coefficient is referred to as the penetration coefficient. With inelastic model, no oscillation is generated during an impact, resulting in improved numerical robustness and efficiency. But inelastic stop model has a feature that you must consider while selecting the model: colliding bodies continue slowly moving into each other as long as the contact is loaded with the compressing force. In real life, this phenomenon is similar to collision of two bodies separated by a sizable layer of viscous liquid. It takes some time to squeeze the liquid before bodies themselves come into contact.
Connections R and C are mechanical translational conserving ports corresponding to the cylinder rod and cylinder clamping structure, respectively. Connection A is a hydraulic conserving port associated with the cylinder inlet. The physical signal output port P shows current rod extension.
Pressure at port A generates force in the direction specified by the Cylinder orientation parameter.
Basic Assumptions and Limitations
Friction between moving parts is not taken into account.
Inertia effects are not taken into account.
Fluid compressibility is not taken into account.
Leakage flows are assumed to be negligible.
The hard stops are assumed to be fully inelastic, as explained above.
- Piston area
Effective piston area. The default value is
- Piston stroke
Piston maximum travel between caps. The default value is
- Initial distance between piston and cap
The distance between the piston and cap at the beginning of simulation. This value cannot exceed the piston stroke. The default value is
0, which corresponds to the fully retracted position.
- Penetration coefficient
Specifies the penetration property of colliding bodies. The higher the value of the coefficient, the less the bodies penetrate into each other, but the sharper the increase of the impact force. To find out the value of the coefficient for a particular application, it is recommended to run the same model with different hard stop models (or with different cylinder models) until they show close results. The default value of the coefficient is
- Cylinder orientation
Specifies cylinder orientation with respect to the globally assigned positive direction. The cylinder can be installed in two different ways, depending upon whether it exerts force in the positive or in the negative direction when pressure is applied at its inlet. If pressure applied at port A exerts force in negative direction, set the parameter to
Acts in negative direction. The default value is
Acts in positive direction.
The block has the following ports:
Hydraulic conserving port associated with the cylinder inlet.
Mechanical translational conserving port associated with the cylinder rod.
Mechanical translational conserving port associated with the cylinder clamping structure.
Physical signal output port that outputs rod extension.

In 2002, Luciano Floridi published a paper called What is the Philosophy of Information?, where he argues for a new paradigm in philosophical research. To what extent should his proposal be accepted? Is the Philosophy of Information actually a new paradigm, in the Kuhninan sense, in Philosophy? Or is it only a new branch of Epistemology? In our discussion we will argue in defense of Floridi's proposal. We believe that Philosophy of Information has the types of features had by other areas already acknowledge as authentic in Philosophy. By way of an analogical argument we will argue that since Philosophy of Information has its own topics, method and problems it would be counter-intuitive not to accept it as a new philosophical area. To strengthen our position we present and discuss main topics of Philosophy of Information.

Calculate the mass of ice required to lower the temperature of 300 g of water 40°C to water at 0°C.
(Specific latent heat of ice = 336 J/g, the Specific heat capacity of water = 4.2J/g°C)
Let m be the mass of the ice to be added.
Heat energy required to melt to lower the temperature is = mL = m x 336
Heat energy imparted by the water in fall of its temperature from 40°C to
0°C = mass of the water x specific heat capacity x fall in temperature
= 300 x 4.2 x 40°C
If there is no loss of heat,
m x 336 J/g = 300 g x 4.2 J/g°C x 40°C
':. m = (300 xx 4.2 xx 40)/336'
∴ m = 150g

What could an indigenous small-scale industry provide for the welfare of a community and its inhabitants? Is it possible to boost their development?
The answer is: Yes. Take a look at kalamay industry in the upland agri-tourism town of Indang in the province of Cavite.
If Los Baños, Laguna is known for the utilization of agricultural products to make their buko pie, then the municipality of Indang does the same in producing "Kalamay Indang," also known as "Kalamay Buna," named after the place where it is originally made: Barangay Buna Lejos, Indang, Cavite.
Kalamay Buna or Kalamay Indang, designated as the area's one-town-one-product (OTOP) by Cavite's Department of Trade and Industry (DTI), has been a famous local delicacy for more than a century.
Kalamay Indang is recognized by the DTI as Indang's one-town-one-product (OTOP) commodity. It is also a well-known product of the Philippines reaching various countries worldwide.
This traditional "kakanin" is described as sweet and chewy. It is made of glutinous rice, coconut milk, brown sugar, and fortified with young coconut meat or ripe jackfruit strips. The term "kalamay" can also be spelled thus: "calamay."
The Department of Labor and Employment Regional Office IV-A, in cooperation with the Cavite Provincial Cooperative, Livelihood and Entrepreneurial Development Office (PCLEDO), sponsored the Kalamay Buna Product Development and assisted the Samahan ng Magkakalamay ng Buna Lejos to improve their livelihood project.
The group further enhanced their skills and improved their products through the technical assistance of the DTI and financial support of the municipality of Indang by way of the skills training program and Bottom-Up Budgeting (BUB) project, respectively.
Through the DOLE and DTI, their product has been standardized and well-packaged. There are two kinds of packaging: the square box contains 12 pieces of smaller kalamay worth PhP 50 while the rectangular box with 10 pieces of large kalamay is worth PhP 100.
Likewise, the municipality of Indang, under the leadership of Mayor Perfecto V. Fidel and Vice Mayor Ismael dM. Rodil, facilitated the construction of a building near the old Indang municipal hall to serve as an outlet for kalamay. It has been dubbed "Bahay Kalamay" and is the town's "pasalubong" (souvenir) center.
The lifespan of Kalamay Indang is two weeks, even if not refrigerated. Kalamay is a favorite present or pasalubong for loved ones, officemates, and friends. Among the major customers are the relatives of the more than 14,000 students studying in the main campus of the Cavite State University in this busy town.
Kalamay-making in Indang is an old industry. One of its eldest practitioners is Librada T. Costa, a 95-year old native of Buna Lejos and an experienced kalamay producer who learned her skills from her parents. She started making kalamay at age 18. Over more than seven decades in the industry, she was able to send all her seven children to college, and they finished their respective courses.
Indeed, Kalamay Indang is a thriving indigenous industry of the town and has contributed to the economic welfare and development of this agri-tourism first class municipality and its populace.

Whilst we are primarily a Bird Club we are also very interested in non-bird records from offshore.
Most of our non-bird records relate to cetaceans - whales, dolphins and porpoises, and insects such as butterflies and moths. We also have records of fish, turtles and bats.
Identifying marine animals is often more difficult than identifying birds and wherever possible a brief sketch/description should be made of what is visible if identification is not certain. E.g. any white areas, shape of dorsal fin etc.
Some useful hints are provided by Caroline Weir, who verifies our marine animal observations. You can improve your identification by being familiar with what is and what isn't common in the North Sea. We have further information on the identification of cetaceans.
We welcome all insect reports - even though many are sent in dead! Butterflies and moths found dead should only be sent in to the Recorder if they cannot be identified offshore.
Initially, a photograph could be emailed to us to assist in identification. Colleagues at Aberdeen University can assist in the identification of specimens sent in or for whichphotographs have been emailed to us.
Occasionally, bats are found offshore - often alive. These cannot be sent onshore without following an established procedure.
Prof. Paul Racey of Aberdeen University has provided guidelines which should be adhered to in the event that a bat is found.
Bat records from offshore have provided useful information on the Nathusius' Pipistrelle - a species found primarily on the European mainland.

will from now on fix the ordering to, that is, we are considering the contribution in (2.10). The remaining terms can simply be obtained through permutation of labels.
We have just seen that the part is nothing but the color-ordered amplitude. We therefore turn our attention to the part, investigating which contours the imaginary terms dictate for the integrals. Near the quantity is a positive imaginary number (remember that ), so the contour is above the real axis here. For we have which is a negative imaginary number, hence the contour lies below the real axis. Finally, for we see that, meaning that the contour for lies below the contour of for. See Figure 1 for an illustration of this nested structure.
The next step is to deform the contours for into expressions corresponding to color-ordered amplitudes. That is, we are going to close the contours either to the left, turning the contour below the real axis, or to the right, turning the contour above the real axis. Besides having the correct integration region, in order to identify the integrals with amplitudes, we also need to make sure that the integrand is correct. This implies that we sometime need to pull out phase factors. However, in order not to cross a branch cut we do this in the following way: for with We have added some additional details concerning this subtle, but important, point in Appendix A.
Furthermore, there is a freedom in the number of contours one can close to the left or the right. For a given, we can pull the contours from 2 up to to the left, and the set from to to the right ( or means all to the right or all to the left, resp.). Let us illustrate this in details for the five-point case (the four-point case is a bit to simple in order to capture all the features of the general argument).
2.1. Five-Point KLT Relations
Starting with, pulling the contour for to the left, only showing the piece involving, we get Note that in the previous first line we write instead of and instead of in order to compensate for the same swapping of order in the integral of (2.11). Now, as illustrated in the bottom of Figure 2, we also close the contour for to the left (only showing the part involving the variable) We see that the total integration over and exactly correspond to color-ordered open string amplitudes, which we will denote to distinguish them from the ones following from the part, such that the whole contribution in can be written as Together with (2.11) for, and (2.10), we have obtained the following relation between the five-point closed string amplitude and the color-ordered open string amplitudes, If we take the other extreme, that is, closing both contours to the right (), we get for the integration, and for the integration, see the top case of Figure 2, that is, Finally, we could have closed to the left and to the right, as also illustrated in Figure 2, resulting in ()
All of these different forms can be nicely collected into one compact formula if we introduce the momentum kernel where equals 1 if the ordering of and is opposite in and, and 0 if the ordering is the same. Here we have defined for a general number of legs, so, for instance and so on. We will also define for empty sets. With this function we can collect (2.16), (2.19), and (2.20) into one formula as with. Note that when one should read the set as being empty, and likewise for the set is empty.
2.2. General -Point KLT Relations
Equation (2.23) not only collects all the different five-point forms, due to different ways of closing the contours, in one nice expression, but going through the same procedure for the -point case, it directly generalizes to with.
Expression (2.24) shows how to factorize an -point closed string amplitude into the product of -point color-ordered open string amplitudes and, "glued'' together by kinematic factors contained in the function. We note that the expression is a sum over terms, taking its maximum value for or, and its minimum for. (The floor and ceiling functions are defined on half-integers as follows: if is odd, or if is even. if is odd, or if is even.)
Although, being one of the expressions having most terms, choosing the relation takes a particularly nice -point form only involving one function and having a greater symmetry between the sums over different ordered and amplitudes. An equally nice form occurs with.
3. The Field Theory Limit
Now that we have obtained the KLT relations in string theory, we will take a closer look at the field theory limit of (2.24), that is, letting. The amplitudes just go to their corresponding field theory expressions and, where it follows from (2.21) that with, or more generally, which will be used later on. Let us at this point also make a slight change in the overall constant such that it fits with a more commonly used normalization of field theory amplitudes. The -point KLT relations in field theory then take the final form again with the freedom. We have not been very explicit about which theories the amplitudes belong to, and as one might have anticipated from the string theory derivation they are actually valid for very general classes of amplitudes. We could, for instance, have an supergravity amplitude on the l.h.s. and SYM amplitudes on the r.h.s., or even express the full tree-level gauge theory amplitude as products between color-ordered gauge theory and a color-scalar theory [13, 19]. However, for simplicity, we will for the rest of this paper just consider it as a relation between pure graviton and pure gluon amplitudes.
Since it will be relevant for a later section, and because of its simple expression, let us explicitly write out the forms one obtains with and, and at the same time introduce a short-hand notation that will be used when expressions get large. With or (3.3) becomes or respectively, see also Figure 3. Here we have introduced the short-hand notation, for a permutation over leg, and likewise for. Note that and are two unrelated permutations, the tilde is just to remind us which one is going with, and we are trying to be economic with our use of Greek letters.
These relations are totally crossing symmetric, which they of course have to be since they equal a gravity amplitude. However, the r.h.s. is only manifest crossing symmetric in legs. The crossing symmetry between, for instance, legs and in (3.4) can also easily be seen by use of the reflection symmetry of color-ordered amplitudes, and the following identity: but in general the crossing symmetry is not obvious at all. These comments also apply in the string theory case.
Although the calculations in Section 2 were a bit involved, at least one had an intuitive picture of breaking up a closed string into two open strings glued together by phase factors. It was also clear how one could get different expressions for this factorization by choosing different closures for the contours. The field theory limit then follows naturally when taking. However, it would be quite unsatisfactory if we could not understand this field theory expression without going through string theory first. This will be our main focus for the remaining of this paper; how to see the KLT relations from a purely field theoretical point of view, including the possibility of going between different expressions without having contours to deform. In order to get a better feel for the task that lies ahead let us start by looking at some explicit lower-point examples and make some comments.
3.1. Lower-Point Examples
The connection between gravity and gauge theory already starts at three points. It is well known that for real momenta an on-shell three-point amplitude must vanish. However, if we go to complex momenta this is no longer the case. Interestingly, it turns out that Lorentz invariance, and the spin of the external particles, uniquely fix the three-point amplitude, see for example,. In detail, the spin 2 three-point amplitude (gravitons) is the product of two spin 1 three-point amplitudes (gluons) This can also be directly seen from Feynman rules when legs are put on-shell, something that in particular simplifies the expression for the gravity three-point vertex. Although we did not have the complex three-point amplitude in mind when we wrote down (3.3), it does give the correct result even in this case. At first it might seem a bit strange to consider amplitudes with complex momenta, but recent progress in amplitude calculations has largely been inspired by such an extension. Indeed, the BCFW recursion relation, that will be reviewed below, relies on the deformation to complex momenta, and so will our proof of (3.3) in Section 4.
The four point case also looks very simple however, its field theoretical origin already becomes a bit unclear here. Compared to (3.7) we see the appearance of a kinematic factor that makes sure to cancel one of the poles present in both gauge theory amplitudes. We also see that the total crossing symmetry of the r.h.s. has already been well hidden, although we know it has to be there.
When we go to five points, even expressed in the form with fewest terms (), not only is the total crossing symmetry of the r.h.s. by no means obvious, but also the correct cancellation of poles begins to get more complicated to see. These properties only get more and more disguised as we increase the number of external particles


Is there a way to write my own syscall/int 0x80 without using them? So, normally it goes like
setup registers
syscall or int 0x80
and I am interested in doing this without syscall/int 0x80
setup registers
call mysyscall
where can I find implementation of syscall or int 0x80? Or is it too low level to implement it in asm?
TL;DR: These are two instructions supported by the CPU, you cannot implement them in assembly, as they are (or aren't) part of the assembly language you're using.
Some more background:
An interrupt (the assembly int instruction is causing a software interrupt) is a special event for the CPU. The CPU immediately (This is slightly inaccurate as advanced performance optimizations and low-level features are ignored for the sake of simplicity) stops executing the instruction sequence it was executing, saves the context of the current execution (such as the EIP and other control registers, most not directly accessible to the user), and switches to a specifically designated code sequence that is in charge of handling that specific interrupt.
Examples of hardware interrupts are related to handling power, hard-disk network and other peripherals, as well as when a program fails accessing a memory region, fails with certain calculations (divide by zero), floating point errors, tries executing a privileged or an invalid instruction and many others.
Additionally, a program can intentionally trigger an interrupt by using the int instruction which receives a single operand - the interrupt id to trigger.
When an interrupt happens, the resumes execution at the address pointed by the interrupt index in the Interrupt Descriptor Table (aka Interrupt Vector Table), in the case of int 0x80, that's the address at offset 0x80, obviously.
As interrupts are an expensive operation for the CPU (it entails a lot of bookkeeping related to theads and context switches, among other things), AMD (and later Intel) introduced the sysenter instruction (called syscall by Intel). That instruction keeps bookkeeping to the minimum by only raising to ring0 and executing kernel code.
Your Answer


Azure SQL and Managed Identity
Azure SQL has a close relationship with Azure Storage. Features like Polybase, backups, extended events and more make use of Azure Storage.
On Azure SQL Database, probably the most common use is Extended Events. When we create a file target, we need to point to the Azure Storage URL where the file will be stored.
Using Keys
In order to access Azure Storage, we need to control the authentication. The most common way is to use credentials, creating a credential with the storage SAS key
. Graphical user interface, text, application, email
Description automatically generated
Once we generate the SAS key, we create the credential object inside our database. For this we have Database Scoped a new feature introduced exactly for these situations, allowing us to create the credential inside the database, instead of at server level.
The statement to create the credential would be like this:
CREATE DATABASE scoped credential
The Identity value is fixed, to identify the kind of key we are using, a SAS key. The name needs to be the URL to the container, but not always, it depends on what feature will be using this credential.
Some more recent features are prepared to use credentials, receiving the name of the credential as a parameter. In these cases, the credential can have whatever name we would like.
However, older features, such as Extended Events, are not prepared to be linked to a credential. This is solved by ensuring the credential name has the same name of the path used by the feature. In this way, SQL Server identifies which credential should be used for that access.
Avoiding Keys
This method ends up spreading SAS keys all around. We can't really tell this is unsafe, since the credentials are kept encrypted using the SQL Server encryption system, but it would be better if we could make the authentication without directly using a key or password.
That's what we can achieve using Managed Identities. Each service on Azure can have its own identity registered with Azure Active Directory. Once the identity is stablished, we can use Role Based security (RBAC) to set permissions for the service, avoiding the use of passwords or keys.
Azure SQL Database doesn't have a control on the UI to set the managed identity, but we can easily do it using PowerShell in the cloud shell on the portal.
Graphical user interface, text, application
Description automatically generated
The statement to set the managed identity is like this:
Setting Identity Permissions
Once we execute this statement, the server gets an identity, and we can use this identity to control the access to the Azure Storage. The next step is to give permission to this identity.
When dealing with RBAC permissions it's important to mind there are two kinds of permissions: Object permissions, for managing the object, and data permission, to access the data within the object. In this case, we need the data permissions, so SQL Server will be able to write the extended events file to the blob storage. We can set the Managed Identity with the permission Storage Blob Data Contributor, which is different than Storage Blob Contributor.
On the storage account, we access the tab Access Control (IAM) and click the Add button. A new window will open, where we configure the identity and permission. The permission is set on Role dropdown, we just choose it. We type on the Select text box to filter the identities. The Manage Identity will have the same name as the SQL Server we created. Once found, we select it and complete the creation of the role assignment.
Graphical user interface, text, application
Description automatically generated
Next step is creating a credential in the database to use the managed identity. This time we don't have a secret for the credential, we only define the type of Identity we will use:
CREATE DATABASE scoped credential
= 'Managed Identity';
Creating the XE Session
This is only an example of an Extended Events session pointing to the blob storage. It will use the credential to authenticate and, in our example, will be using the SQL Server Managed Identity.
ADD EVENT sqlserver.sql_statement_completed(

ELF Danger: True? How To Protect Yourself?
Laura from U.S. writes:
Is there such a thing that can negate ELF's? My housemate insists on turning the wireless off at night as she has read all sorts of scary things about ELF's coming from wireless devices. Is there something I can attach to it that will negate the ELF's and keep the unit going all night but harmless to humans? Do you have any articles on it?
ELF or Extremely Low Frequency, refers to radiation emitted in the 1 Hz to 300 Hz range usually associated with power lines or electrical wiring. This type of radiation has been linked (in some studies, it is still a controversial subject with proof on both sides) to increased risk of cancer.
Since Wi-Fi operates in 2.4 Ghz or 5 Ghz spectrum, ELF related studies would not be applicable to home Wi-Fi networks. There has been no accepted mainstream research to date linking Wi-Fi signals to health risks.
If your house mate still insists on turning off Wi-Fi, you may be able to switch to a wired plug. But you'll need a wired Ethernet jack on any device you want to connect to the Internet. You could plug an Ethernet cable from your router into the device's Ethernet port and access the internet. If you have the router in a different room, you might consider buying powerline network adapters, which use your homes power lines as cables.

Associations of Physical Activity with Mental Health and Work Engagement
- Presented on April 2014
Background and Aim: Research on physical activity and mental health has mainly focused on mental disorders. However, mental health is not merely the absence of disorders but also comprises well-being. An indicator of work-related well-being is work engagement. The aim of this study was to explore associations of moderate to vigorous physical activity (MVPA) with work engagement and general mental health.
Methods: 257 employees self-reported their MVPA, mental health and level of work engagement using validated questionnaires, including the SQUASH, RAND-36, and UWES, respectively. In addition, a randomly chosen subgroup (n=100) wore an Actigraph accelerometer for a 1-week period to measure their MVPA objectively. Crude and adjusted associations between MVPA and both work engagement and mental health were analyzed using linear regression analyses.
Results: There was no statistically significant association between self-reported MVPA or objectively measured MVPA with mental health (adjusted: b=0.026; 95% CI -0.158- 0.210 and b=-0.199; 95% CI 1.417- 1.018, respectively). There was also no significant association between self-reported or objectively measured MVPA with work engagement (adjusted: b= 0.002; 95% CI -0.010- 0.013 and b=0.007; 95%CI -0.083-0.069, respectively).
Conclusions: This study found no evidence for the beneficial effects of MVPA on positive aspects of mental health. The possible difference in how the physical activitymental health relationship works for negative and positive sides of (work-related) mental health should be considered in future studies.

I just came across the lovely and unreal set of gear constructions – that seem to work when you watch the videos. At first I thought this was a one-off project by a student but there seems to be more science behind the geometries of these paradoxical gear sets.
From Jacques Maurel's explanation on his website:
"…This gear pair has been invented by Mr. Mercier of Renault automobile company, and has been patented in 1988 – it was to be used in a special differential providing "torque transfer" This model below shows 2 pulleys with a crossed belt – a knot giving a point on the belt. With a felt pen, it is possible to point out the trajectory of this point on a disc locked by a pin to the left pulley (red spots) and afterward, on a disc locked to the right pulley (green spots). These spotted lines are the involute curves, which will give the profile of the teeth. The pulleys are turning in opposite directions. But look at photo 4, showing a straight (non-crossed) pulleys and belt mechanism, the 2 same involute curves are still meshing together, but the pulleys are now turning in the same direction – This gives the paradoxical gear pair."

The Impact of the Adversary's Eavesdropping Stations on the Location Privacy Level in Internet of Vehicles
The Internet of Vehicles (IoV) has got the interest of different research bodies as a promising technology. IoV is mainly developed to reduce the number of crashes by enabling vehicles to sense the environment and spread their locations to the neighborhood via safety-beacons to enhance the system functioning. Nevertheless, a bunch of security and privacy threats is looming; by exploiting the spatio-data included in these beacons. A lot of privacy schemes were developed to cope with the problem like CAPS, CPN, RSP, and SLOW. The schemes provide a certain level of location privacy yet the strength of the adversary, e.g., the number of eavesdropping stations has not been fully considered. In this paper, we aim at investigating the effect of the adversary's eavesdropping stations number and position on the overall system functioning via privacy and QoS metrics. We also show the performances of these schemes in a manhattan-grid model which gives a comparison between the used schemes. The results show that both the number and the emplacement of the eavesdropping stations have a real negative impact on the achieved location privacy of the IoV users.

As we learned in yesterday's daf, Abaye was surprised to find that his teacher, Rabba, permitted a non-Jew to be asked to bring hot water to facilitate a brit mila on Shabbat in a place where there was no eiruv.
Abaye asked why completing the ritual to purify someone who had become tame which is forbidden on Shabbat by the Sages – cannot be performed even if it is necessary to perform a mitzva (e.g. to sacrifice and eat the Passover sacrifice), yet in our case, asking a non-Jew to bring water for the brit is permitted?
The Gemara's response to Abaye's question is that we distinguish between an "active" Rabbinic prohibition and a "passive" one. How to understand this distinction depends on different girsa'ot – variant readings – in the Gemara.
The standard text of the Gemara argues that the case of the brit is passive because Rabba did not ask the non-Jew to heat the water, only to bring the water. According to this reading, our case is passive because the activity that was done was just moving something from one place to another, rather than being a creative activity.
Rabbenu Hananel has a different text of the Gemara, which does not have the explanation that focused on whether the non-Jew needed to heat the water up. According to this version, the difference is between the Rabbinic decree of Amira la-Akum (asking a non-Jew to perform a forbidden act on) and other Rabbinic ordinances, which involve direct activity, not merely speech, which is not considered an active behavior.
The Ra'avad argues that this case is unique because it involves two Rabbinic ordinances – a shvut d'shvut. First of all, there is no action, only a request made by speaking. Secondly, the activity performed by the non-Jew – transferring water from the house to the courtyard – is, itself, not forbidden by the Torah, but only by the Rabbis. In this case, where it is necessary in order to perform the brit mila, the Rabbis never would have applied their restrictions.

Portable safe drinking water is a challenge for communities living in Nyangombe area in Nyanga District.
Water to drink comes from river, unprotected wells, and dams. When ActionAid International Zimbabwe and their partner Fact Nyanga identified this problem they thought of ways to intervene to reduce the impact of unsafe water on the communities.
Through the Emergencies unit a sand technology was identified that could help these people in the name of bio-sand filter. This technology uses three layers of sand of different sizes to filter the water. Besides the sand particles filtering the water after a number of days the process also relies on a bio-layer that also assists in ensuring that no foreign particles or bacteria passes the sand. The water that comes out of the bio-sand filter is free of any disease causing organisms. If tested it is 97 -99.9 percent pure and can be used safely within communities.
The organisation procured 375 bio-sand filters for distribution in its various operational areas in 2010. Communities in Makoni, Chiendambuya and Nyanga in Manicaland, Nkayi in Matabeleland North and Hwedza in Mashonaland East were beneficiaries of the bio-sand programme. At total of 375 people, 70 percent of which were women, benefitted from the programme.
The objective of the program was to reduce cholera and water borne diseases through provision of clean, safe portable water for household use.
The provision of safe water was therefore done through this innovation which is available locally from our partner one way ministries. Other non benefiting villages have expressed interest after seeing how it works.

Pathé or Pathé Frères (French pronunciation: [pate fʁɛʁ], styled as PATHÉ!) is the name of various French businesses founded and originally run by the Pathé Brothers of France from 1896. In the early 1900s, Pathé became the world's largest film equipment and production company, as well as a major producer of phonograph records. In 1908, Pathé had invented the newsreel that was shown in theaters prior to a feature film.
The company was founded as Société Pathé Frères (Pathé Brothers Company) in Paris, France on 28 September 1896, by the four brothers Charles, Émile, Théophile and Jacques Pathé. During the first part of the 20th century, Pathé became the largest film equipment and production company in the world, as well as a major producer of phonograph records.
The driving force behind the film operation was Charles Pathé, who had helped open a gramophone shop in 1894 and then established a phonograph factory at Chatou on the western outskirts of Paris. As these became successful, he saw the opportunities offered by new means of entertainment and in particular by the fledgling motion picture industry. Having decided to expand the record business to include film equipment, Charles Pathé oversaw a rapid expansion of the company. To finance its growth, he took the company public under the name Compagnie Générale des Établissements Pathé Frères Phonographes & Cinématographes (sometimes abbreviated as "C.G.P.C.") in 1897, and its shares were listed on the Paris Stock Exchange.
In 1902, Pathé acquired the Lumière brothers' patents and then set about to design an improved studio camera and to make their own film stock. Their technologically advanced equipment, new processing facilities built at Vincennes, and aggressive merchandising combined with efficient distribution systems allowed them to capture a huge share of the international market. They first expanded to London in 1902 where they set up production facilities and a chain of movie theaters. By 1909, Pathé had built more than 200 movie theaters in France and Belgium and by the following year they had facilities in Madrid, Moscow, Rome and New York City plus Australia and Japan. Slightly later, they opened a film exchange in Buffalo, New York. Prior to the outbreak of World War I, Pathé dominated Europe's market in motion picture cameras and projectors. It has been estimated that at one time, 60 percent of all films were shot with Pathé equipment. In 1908, Pathé distributed Excursion to the Moon by Segundo de Chomón an imitation of Georges Melies a Le Voyage Dans La Lune ("A Trip to the Moon"). Pathé and Melies worked together in 1911. Georges Melies made a film Baron Mucherons Dream, his first film to be distributed by Pathé. Pathé's relationship with Melies soured, and in 1913 Melies went bankrupt, and his last film was never released by Pathé.
Worldwide, the company emphasized research, investing in such experiments as hand-coloured film and the synchronisation of film and gramophone recordings. In 1908, Pathé invented the newsreel that was shown in theaters prior to the feature film. The news clips featured the Pathé logo of a crowing rooster at the beginning of each reel. In 1912, it introduced 28 mm non-flammable film and equipment under the brand name Pathescope. Pathé News produced cinema newsreels from 1910, up until the 1970s when production ceased as a result of mass television ownership. In the United States, beginning in 1914, the company's film production studios in Fort Lee, New Jersey produced the extremely successful serialized episodes called The Perils of Pauline. By 1918 Pathé had grown to the point where it was necessary to separate operations into two distinct divisions. With Emile Pathé as chief executive, Pathé Records dealt exclusively with phonographs and recordings while brother Charles managed Pathé-Cinéma which was responsible for film production, distribution, and exhibition. 1922 saw the introduction of the Pathé Baby home film system using a new 9.5 mm film stock which became popular over the next few decades. In 1921, Pathé sold off its United States motion picture production arm, which was renamed "Pathé Exchange" and later merged into RKO Pictures, disappearing as an independent brand in 1931. Pathé sold its British film studios to Eastman Kodak in 1927 while maintaining the theater and distribution arm.,
Natan to Parretti
Pathé was already in substantial financial trouble when Bernard Natan took control of the company in 1929. Studio founder Charles Pathé had been selling assets for several years to boost investor value and keep the studio's cash flow healthy. The company's founder had even sold Pathé's name and "rooster" trademark to other companies in return for a mere 2 percent of revenues. Natan had the bad luck to take charge of the studio just as the Great Depression convulsed the French economy.
Natan attempted to steady Pathé's finances and implement modern film industry practices at the studio. Natan acquired another film studio, Sociètè des Cinéromans, from Arthur Bernède and Gaston Leroux, which enabled Pathé to expand into projector and electronics manufacturing. He also bought the Fornier chain of motion picture theaters and rapidly expanded the chain's nationwide presence. The French press, however, attacked Natan mercilessly for his stewardship of Pathé. Many of these attacks were antisemitic.
Pathé-Natan did well under Natan's guidance. Between 1930 and 1935, despite the world economic crisis, the company made 100 million francs in profits, and produced and released more than 60 feature films (just as many films as major American studios produced at the time). He resumed production of the newsreel Pathé News, which had not been produced since 1927.
Natan also invested heavily into research and development to expand Pathe's film business. In 1929, he pushed Pathé into sound film. In September, the studio produced its first sound feature film, and its first sound newsreel a month later. Natan also launched two new cinema-related magazines, Pathé-Revue and Actualités Féminines, to help market Pathé's films and build consumer demand for cinema. Under Natan, Pathé also funded the research of Henri Chrétien, who developed the anamorphic lens (leading to the creation of CinemaScope and other widescreen film formats common today).
Natan expanded Pathé's business interests into communications industries other than film. In November 1929, Natan established France's first television company, Télévision-Baird-Natan. A year later, he purchased a radio station in Paris and formed a holding company (Radio-Natan-Vitus) to run what would become a burgeoning radio empire.
But in 1935, Pathé went bankrupt. In order to finance the company's continued expansion, Pathé's board of directors (which still included Charles Pathé) voted in 1930 to issue shares worth 105 million francs. But with the depression deepening, only 50 percent of the shares were purchased. One of the investor banks collapsed due to financial difficulties unrelated to Pathé's problems, and Pathé was forced to follow through with the purchase of several movie theater chains it no longer could afford to buy. Although the company continued to make a profit (as noted above), it lost more money than it could bring in.
The collapse of Pathé led French authorities to indict Bernard Natan on charges of fraud. Natan was accused of financing the purchase of the company without any collateral, of bilking investors by establishing fictitious shell corporations, and negligent financial mismanagement. Natan was even accused of hiding his Romanian and Jewish heritage by changing his name. Natan was indicted and imprisoned in 1939. A second indictment was brought in 1941, and he was convicted shortly thereafter. He was freed in September 1942.
The company was forced to undergo a restructuring in 1943 and was acquired by Adrien Ramauge. Over the years, the business underwent a number of changes including diversification into producing programs for the burgeoning television industry. During the 1970s, operating theaters overtook film production as Pathé's primary source of revenue. In the late 1980s, Italian financier Giancarlo Parretti tried to make a bid for Pathé, even taking over a smaller distributor and renaming it Pathé Communications in anticipation of owning the storied studio. Parretti's shady past, however, raised enough eyebrows in the French government that the deal fell through. It turned out to be a fortunate decision, as Parretti later took over Metro-Goldwyn-Mayer, only to lose it in a bankruptcy.
Jérôme Seydoux
In 1990 Chargeurs, a French conglomerate led by Jérôme Seydoux, took control of the company. As a result of the deregulation of the French telecommunications market, in June 1999 Pathé merged with Vivendi, the exchange ratio for the merger fixed at three Vivendi shares for every two Pathé shares. The Wall Street Journal estimated the value of the deal at US$2.59 billion. Following the completion of the merger, Vivendi retained Pathé's interests in British Sky Broadcasting and CanalSatellite, a French broadcasting corporation, but then sold all remaining assets to J

We introduce the Concave-Convex procedure (CCCP) which con(cid:173) structs discrete time iterative dynamical systems which are guar(cid:173) anteed to monotonically decrease global optimization/energy func(cid:173) tions. It can be applied to (almost) any optimization problem and many existing algorithms can be interpreted in terms of CCCP. In particular, we prove relationships to some applications of Legendre transform techniques. We then illustrate CCCP by applications to Potts models, linear assignment, EM algorithms, and Generalized Iterative Scaling (GIS). CCCP can be used both as a new way to understand existing optimization algorithms and as a procedure for generating new algorithms.


The Weil Pairing
Consider the group of $m$-torsion points $E[m]$ for some $m$ coprime to $q = \mathrm{char} K$.
For a point $T \in E[m]$, find a $T_0$ such that $m T_0 = T$ (i.e. $T_0 \in [m]^{-1}(T)$). Let $g_T$ be a rational function with divisor
\[ \langle g_T \rangle = \sum_{R\in E[m]} \langle T_0 + R \rangle - \langle R \rangle \]
Let $\tau_S$ be the translation-by-$S$ map for some $m$-torsion point $S$. Then define the Weil pairing to be
\[ e(S,T) = \frac{g_T \cdot \tau_s }{ g_T } \]
Since $R, S$ are both elements of the group $E[m]$:
\[ \langle g_T \cdot \tau_S (P) \rangle = \sum_{R\in E[m]} \langle T_0 + R - S \rangle - \langle R - S \rangle = \langle g_T \rangle \]
So $g_T$ and $g_T \cdot \tau_S$ have the same divisor which implies $e(S, T) = g_T \cdot \tau_S / g_T = \mu$ for some constant $\mu$ (recall that $g_T$ is unique up to a constant).
Repeating this argument gives $g_T \cdot \tau_S^i = \mu^i g_T$. Since $m$ translations by $S$ is the identity (since $S \in E[m]$) we find $\mu^m = 1$, when $i = m$. In other words $e(S,T) = \mu$ is an $m$th root of unity.
So we may view the Weil pairing as a map
\[ e : E[m] \times E[m] \rightarrow \mu_m \]
where $\mu_m$ is the group of the $m$th roots of unity.
Note this definition of the Weil pairing is not suitable for practical computations as the representations of the functions $g_T(P), g_T(P+S)$ grow quickly with $m$. (There are $2m^2$ poles and zeroes for each function, which means each function is a product of $2m^2$ line equations.) Fortunately an alternative definition of the Weil pairing lends itself well to explicit computation.
Pullback of Divisors
This is another way to view this definition of the Weil pairing.
Suppose $\alpha$ is an endomorphism, and $g$ is a rational function. Then a natural construct is to compose $g$ and $\alpha$, i.e. $g \cdot \alpha$.
For example, if $\alpha$ is translation by a point $T$, then $g \cdot \alpha (P)= g(P+T)$.
The map $\alpha$ also induces a map on the divisors $\alpha^* : Div(E) \rightarrow Div(E)$ that takes the divisor of $g$ to the divisor of $g \cdot \alpha$.
For example, if $\alpha$ is translation by $T$, then $\alpha^*$ takes a divisor $\sum m_P \langle P \rangle$ to $\sum m_P \langle P - T \rangle$.
Then the function $g_T$ in the Weil pairing may be defined as a function such that
\[ \langle g_T \rangle = [m]^*(\langle T \rangle - \langle O \rangle) \]
Properties of The Weil Pairing
The Weil pairing is nondegenerate, alternating and bilinear.
 - $e(S_1 + S_2, T) = e(S_1, T) e(S_2, T)$
 - $e(S, T_1 + T_2) = e(S, T_1) e(S, T_2)$
 - $e(S, S) = 1$
 - $e(S, T) = e(T, S)^{-1}$
 - $e(S, T) = 1$ for all $T$ if and only if $S = O$
 - $e(S, T) = 1$ for all $S$ if and only if $T = O$
 - For any nonzero endomorphism $\alpha$, $e(\alpha(S), \alpha(T)) = e(S,T)^{\deg \alpha}$
 [TODO: define degree of endomorphism]

Title: Theseus at the Gates of the Labyrinth
Subtitle: Interpreting a Pompeian Painting
Author(s): LING, Roger
Volume: 84 Date: 2009
A painting of Theseus and Ariadne in the House of M. Lucretius Fronto at Pompeii shows the moment when the princess hands the hero the ball of wool that will enable him to find his way out of the Labyrinth; but the action of Theseus, who holds his arm over his head with a fillet dangling from the hand, presents a problem of interpretation. A recent theory has proposed that he is crowning himself after his victory over the Minotaur and, therefore, that the painting combines two moments in time: the preparations for the expedition into the Labyrinth and the celebrations after its successful outcome. The present paper suggests, by analogy with other Pompeian paintings of the same subject, that Theseus is actually removing his sword prior to entering the Labyrinth naked and unarmed. This is an iconographic variant found only at Pompeii and only for a brief period shortly before the middle of the 1st century AD.

About the build:
'Bleeding Books' begins in the sky, and drops to the large fortress at ground level. It is a story in my ongoing series on abuse as seen through the lens of language. What happens when knowledge is so disrespected that it is freely contaminated with doses of falsehood? There are avenues to properly sort facts in this information age, yet we easily turn a blind eye to certain evidence if it goes counter to our beliefs – even when our choices may cause immeasurable harm. In the exhibit, the texts of books bleed falling letters of the alphabet, for they can no longer contain any structure of value.

Abdul Hameed Masho Gagar.ماشوگاگر
Died circa 1732
Residence about 14 km from Peshawar City on Kohat Road
Ethnicity Pashtun
Known for Pashto Poetry
Religion Islam
Abdul Hameed Mashokhel (Pashto: عبدالحميد ماشوخېل - also known as Abdul Hamid Baba), was a Pashtun poet and Sufi figure.[1]
Abdul Hameed Masho Gagar was born in the second half of the 17th century at Mashu Gagar, a small village controlled by the Kudrizi branch of the Mohmand clan, a Pashtun tribe. Hameed travelled to Peshawar, where he undertook his education, and became a priest. At this point, Hameed was a man of considerable stature among intellectuals, and students from a number of surrounding districts came to receive instruction from him.[2]
Hameed's poetry was written primarily in the Pashto language. His poems generally had a moral to them, and were often tinged with tones of contempt for the world and its lack of virtue. The morals of his poems were based on Sufism, as a large proportion of other Muslim poetry was. Hameed's poetry was popular even in Persia, where he was dubbed "Hameed the Hair-splitter". Hameed's major works, Love's Fascination, The King and the Beggar and Pearls and Corals have all been translated into English.[2]
Hameed's exact death date is not known, but it is thought by those in his home village that he died around the year 1732. He died in the same house that he had lived in for most of his life.[2]

The University of Arizona (UA) Campus Health Service (CHS) and the Southwest institute for Research on Women (SIROW), propose Project Lifeline, a comprehensive suicide prevention strategy to reduce the incidence of suicide, suicide attempts, and their related risk factors such as alcohol and other drug (AOD) misuse/abuse among students at the UA with a special emphasis on high-risk student populations, such as LGBTQ students and veterans. Located in Tucson, UA is a large public institution (over 43,000 students) with over 45% of its student population from an ethnic/racial minority and 52% female. Approximately 5-6% of the population identifies as LGBQ and over 1,000 students are veterans receiving GI Bill benefits. On a 2017 survey 63% of UA students reported having consumed alcohol, 28% reported having used marijuana, 2% reported having used pain pills, and 6% reported having used sedatives not prescribed to them in the past 30 days. Seventeen percent had been diagnosed with depression and 19% with anxiety. Forty five percent had felt hopeless, 81% had felt overwhelmed, 30% felt so depressed it was difficult to function at least once during the past year. Seventeen percent reported at least mild suicidality, 1.4 reported attempting suicide, and 3 committed suicide in the past school year. These risk factors indicate the strong need for comprehensive suicide prevention on campus.
In collaboration with a wide variety of campus and community partners, CHS and SIROW's Project Lifeline will address the following objectives:
- Increase collaboration among campus departments and the Tucson community to address student mental and behavioral health needs;
- Increase knowledge and willingness of students and campus personnel (gatekeepers) to respond effectively to students with mental health (MH) and behavioral health (BH) problems that can lead to school failure, such as depression, substance abuse, and suicidal thoughts and attempts;
- Increase students who are screened and assessed for MH and substance use disorders;
- Increase awareness of campus and community resources that can identify, assess, and treat MH and MH problems;
- Increase help seeking for MH and BH problems;
- Decrease suicide attempts and related risk factors;
- Institutionalize effective program components and disseminate information at local, state, and national levels.
To address these project objectives, the project team will utilize gatekeeper training to 400 individuals/year, educational presentations and curriculum infusion to a minimum of 400 individuals/year and campus-wide efforts such as student driven activities and media (videos, posters, pamphlets, articles) with the potential to be seen by most students (43,000), as well as local, state and national dissemination (presentations, technical assistance and publications).

White House Council on Women and Girls
On March 11, 2009 President Obama signed an Executive Order creating the White House Council on Women and Girls. The mission of the Council is to provide a coordinated federal response to the challenges confronted by women and girls and to ensure that all Cabinet and Cabinet-level agencies consider how their policies and programs impact women and families.
USTR has already taken steps to fulfill the President's goals in this regard. Developing an outreach strategy that incorporates stakeholders from all facets of the community, we are working to ensure that U.S. trade policy is used as an effective tool to benefit women.
Recognizing that trade policy benefits women at home and abroad, USTR is using trade policy to achieve objectives such as poverty reduction, promoting rule of law, and improving the financial and socio-economic status of women and children. Whether through job creation, market access or the improvement in the overall standard of living, including within the home, opportunities can be created to impact the lives of women.
U.S. Free Trade Agreements include provisions to promote more effective and efficient trade capacity building assistance to all sectors of society, including programs that improve the ability of women and girls to participate more effectively in the domestic and global marketplace.
One of the more recent examples of this initiative is in Guatemala where a group of Guatemalan agricultural producers (Labradores) with assistance from USAID, strengthened production and became certified for Good Agricultural and Manufacturing Practices. As a result of its improved ability to comply with international requirements, Wal-Mart signed up Labradores to supply vegetables and fruits to its Central American outlets. The majority of the jobs in the packing plant went to women. This is just one of the many stories of how trade benefits women and girls. Without strong U.S.- Guatemalan trade relations, these jobs would not have solidified.
Such firm-level assistance is a typical trade capacity building mechanism that directly enhances the capacity of smalland medium-scale enterprises throughout Central America and the Dominican Republic.
USTR also administers the four U.S. tariff preference programs that provide enhanced access for developing countries' exports into the U.S. markets. These programs benefit women, who comprise much of the labor force in developing countries both in larger-scale manufacturing operations and in the home.

3 Techniques to increase growth hormone
Yesterday, I featured a new article from nutrition expert John Romaniello (aka, Roman) about the topic of intermittent fasting and how this relates to the conventional fitness nutrition method of 5-6 meals/day. As I said, I like to be open minded and give every viewpoint a fair chance, and Roman made some excellent points in his article.
In fact, over the last 6 months, I've occasionally tested intermittent fasting on myself, although supplemented with BCAA's during fasting times (usually 14-16 hour fasts which included overnight sleep time) to prevent excess muscle breakdown, and I've actually had pretty decent results.
Today, we're back with another great article from Roman on 3 specific methods you can use to increase GH, which is also known as "the fitness hormone", or the "leanness hormone" (as well as the "youth hormone").
3 Techniques that Increase "The Leanness Hormone" in Your Body
By John Romaniello, author of Fat Loss Forever
We briefly touched on the hormonal benefits of fasting in yesterday's article, including an increase in one of the most powerful hormones around: Growth Hormone, or GH. Also known as "the fitness hormone," GH has a myriad benefits, ranging from increased sleep quality to enhanced metabolism. While a full description of this amazing hormone is beyond this writing, it's enough to say that the more GH your produce, the faster you can lose fat and gain muscle.
And so today, I want to share with you the top three instances when you naturally produce more Growth Hormone, and show you a way that you can combine all three to get the best possible outcome--a synergistic BURST of GH production, all leading towards incinerating fat.
Let's take a look.
Three Instances of Naturally Increased Growth Hormone
1) When you sleep
2) When you are in a fasted state
3) When you train with weights.
That's correct -- you produce the MOST growth hormone when you sleep, when you eat, and when you train intensely. So, how do we use this knowledge to increase fat loss?
Well, let's look at it. We know you're producing tons of growth hormone when you're fasting--which means you're NOT producing it when you're eating. We also know you're producing it when you sleep.
So, if you're producing GH when you sleep...why do you STOP producing it when you wake up? EASY--because, when most people wake up, the first thing they do is EAT...which we just said stops growth hormone production.
Which means that by doing something as simple as skipping breakfast (when done strategically) you can extend the natural secretion of growth hormone that occurs during your sleep cycle; in addition, staying in a fasted state will actually help you produce MORE growth hormone.
With just that simple change, you've doubled your fat-burning production of GH. And...forgive me for sounding like an infomercial host, but this is the perfect time to use this line...
"But wait, there's more!"
Because, it actually does get even better.
Oh, wait: that's exactly what we did!
You see, imagine what would happen if you put your GH producing weight training session at the end of your GH-producing fasting session...which was used to extend the effect of your natural GH-producing sleep?
Exactly: you would create a perfect storm production, sending growth hormone production into overdrive, allowing your body to burn fat at an accelerated rate, while you're already in a calorie deficit.
Here's the abbreviated cheat sheet:
1) Get a good night's sleep
2) Push your breakfast back until after your workout
3) Train with weights any time between 12 and 2pm.
Follow those three simple steps, then follow that with a healthy meal. Do those things, and you're on your way to losing fat, and keeping it off forever.
Can you imagine that? By simply skipping breakfast and having a workout, you can likely double or triple growth hormone secretion and burn up to three times as much fat.
Incredible results with minor changes -- that's what Fat Loss Forever is all about.
Thanks Roman yet again for your fitness wisdom!

Can you open fire hydrants to get water for bathing?
Only fire departments, and occasionally other units of local governments, are allowed to open fire hydrants. Because of the significant public safety risk of having inadequate water pressure with which to fight fires, punishment for illegally opening a fire hydrant tends to be severe.
There is a Uniform Fire Code in the United States that sets forth model laws about firefighting and fire protection systems for states to implement. In sections 1001.6.2 of that code, it says: "Fire hydrants and fire appliances required by this code to be installed and maintained shall not be removed, tampered with or otherwise disturbed except for the purpose of extinguishing fire, training, recharging or making necessary repairs, or when allowed by the fire department."
More generally, the section just before that, 1001.6.1 declares that "[a]pparatus, equipment and appurtenances belonging to or under the supervision and control of the fire department shall not be molested, tampered with, damaged or otherwise disturbed unless authorized by the chief."[i] This uniform law might be incorporated into state statutes, but is more likely to be in the municipal or county code[ii] because fire departments, even when operated by volunteers, are authorized by those governments. Because opening a fire hydrant, outside of municipal authority, is an offense against the government, doing so is a crime. Therefore, punishment for violating a fire hydrant law involves at least a ticket and at most a jail term.

In what sources of fresh water can you legally bathe or wash laundry? If waterways are polluted and you get sick from washing in them, does the law entitle you to anything? Can your bathing or washing laundry in rivers or lakes, etc… count as pollution?
You can usually expect that it is probably legal to bathe in naturally existing bodies of water such as lakes, creeks, rivers, and oceans which do not have to be entered through private property and do not have fences or signs declaring them to be off limits.
Use of these natural bodies of water is, however, subject to rules involving the land connected to them. If there is a lake in the middle of a city park that closes at 9:00 p.m., then using that lake for a bath after the park closed at 9:00 p.m. is also illegal. While laws regarding the use of public lands and waterways are often posted on signs, it is also possible that they are simply recorded in the law books, especially when they apply to an entire park system or collection of beaches.[i]
Public fountains are not naturally existing bodies of water. They, and other man-made water-involving exhibits are usually created for the purpose of commemoration or beautification and the government has no obligation to allow people to use them for other purposes like washing. There do not have to be specifically written laws declaring that the public is only allowed to gaze upon the municipal reflecting pond or water display in order for misusing them to be illegal. The police have an array of general misconduct charges that can be legitimately applied against public behavior. See the posts about police and courts for more details about those.
There is a federal law, called the Clean Water Act, which defines water pollution and explains exactly when it is illegal to discharge anything into waterways. Made by Congress, that law "is intended to protect the quality of lakes, streams, and other waters for recreational use, for maintenance of aquatic life, and for drinking water sources."[iii] The federal Environmental Protection Agency and state environmental departments have regulations that detail how that federal law is to be carried out.[iv]
The Clean Water Act makes it illegal for any person to put pollutants including solid waste, garbage, chemical waste, industrial waste, biological residue, etc…[v] into the waterways. Even though the law says "any person" can be guilty of a violation, the Clean Water Act is ordinarily used against businesses that dump or drain out dirty water and against local governments whose waste treatments plants aren't sufficient to treat raw sewage or who fail to prevent excessive debris and biological overflowing when storms wash things into pubic waterways.
This Act, and the various regulations that go with it, are all full of measurements because it simply isn't possible to prevent every bit of pollution from going into public waterways. The laws detail under what circumstances particular quantities of various pollutants can go into waterways.
The small amount of soap or grime that a person bathing or washing clothes might put into the water would be very far below the level of water contamination that would count as pollution, although it can be considered a violation of the local litter ordinance. Typical state and local litter laws have very broad declarations that dumping human waste, garbage, paper, detrimental substances, or other things into rivers or waterways is littering.[vi]
Industries and waste treatment plants have to obtain permits to dump in waterways. To get a permit, it is necessary to identify one's industry and the pollutants that are going to be discharged. The permit process is mainly a way of letting the government know that this company will be submitting regular reports to prove that they are cooperating with the pollution limits in the federal and state regulations.
If a company or municipality allows more pollutants into a waterway than they are supposed to, they will be fined by the EPA or the state environmental agency and, if necessary, sued by the EPA. Private citizens and groups of citizens can also file lawsuits against companies or governments for violating the Clean Water Act,[vii] but because this law is intended to keep waterways clean, the remedy that comes from this kind of lawsuit emphasizes reducing pollution in the water source, not directly aiding individuals who have gotten sick from the water.
Nevertheless, violations of the Clean Water Act are important sources of proof in cases that are about injuries and sickness caused by polluted water. In other words, if a community of homeless people become sick from bathing in polluted water and the EPA or the state environmental agency has documented who caused the pollution, then the homeless people can use those documents as proof of how they got sick and who caused their sickness.
Cases that emphasize the harm done to humans are grouped in a category called "personal injury law." The formal legal term for this category is "torts." Within torts are two general ways that people get injured: intentionally and by negligence. When people get sick or injured by water pollution, the lawsuit is filed on the basis of negligence.
In order to succeed in a negligence case, it is necessary to prove that the defendant owed a duty to the injured plaintiff. The plaintiff also has to prove that the defendant breached that duty, that he (the plaintiff) is suffering harm, and that this harm has been caused by the defendant's breach of his duty. The Clean Water Act and the federal EPA and state regulations that go with the Act all establish the duty that is owed in a negligence case about water pollution.[viii]
A successful Clean Water Act lawsuit, which could have been brought by the EPA or an environmental group or anybody not necessarily the plaintiff in the negligence case, can serve as proof that the duty was breached. So, all that is left for the plaintiff in the negligence case to prove is the extent of his injuries or sickness and the connection between his problems and the polluted water.
A book titled A Civil Action[ix] details the work involved in making a negligence case on behalf of leukemia victims against a company that polluted a local water source. That case was a class action lawsuit on behalf of several families which went through years of expensive preliminary court procedures. It depicts, with great pain, the work and costs involved in collecting evidence and simply trying to ascertain who was truly responsible for contaminating the water. There is also a related book titled A Documentary Companion to A Civil Action[x] which contains many of the actual court papers that were filed in the case. Both of those books would be helpful to somebody thinking about suing for injuries or sickness caused by water pollution. There are also some law library reference books that have practical guidance for working on this kind of lawsuit. One of these, a set called "Am Jur Proof of Facts" has a very detailed article describing how to prepare a case about dioxin poisoning in a water source. It lists the evidence that should be presented, gives checklists of questions to ask experts, includes sample interrogatories identifying the documents to obtain, and generally conveys what information is necessary to prove and present a water pollution case.[xi] Another helpful article from that set is specifically about the role expert witnesses play in proving "toxic torts," personal injuries caused by poisons and pollution. It has sample forms, clear explanations of how experts show that an accused defendant did or did not pollute water, and descriptions of the
