In an auditory interpretation study, Frazier and Clifton (1998; F&C) tested sluices with two indefinite possible antecedents:
With the embedded object (someone) accented, object responses (who was hiding) reached 69%, while accenting the matrix subject (tourist) produced 46% object responses. Accent position significantly affected interpretation, presumably by helping focus the accented element, but object responses remained even with subject accent. This object bias was traced to focus more indirectly, through perceivers' general tendency (in English) to assign focus clause-finally. However, these results could also result from a preference specifically for object antecedents, or for antecedents not separated from the sluice by additional clause boundaries. Additionally, this work explored focus only in indefinite sluices, though other types exist (Romero 1997, Merchant 2001).
An auditory questionnaire addressed alternative explanations using sluices with two VP-internal indefinites:
Two further experiments extended this work to the processing of contrast sluices (with 'else' indicating contrast with a definite antecedent, instead of an indefinite) as in (3):
In a written questionnaire, sentences like (3) received 86% object responses, showing that the preference for a clause-final antecedent holds for contrast sluices. In an auditory questionnaire, object responses fell to 42% with the subject (Alice) accented, vs. 88% with the object (Bill) accented (p's.001). With the verb or both arguments accented, object responses were at 76% (each differed from the subject/object accent conditions, p's.05). These results show that exclusive accent on only one argument is needed to raise focus assignments to that argument, not just the presence of an accent. Finally, despite strong accent effects, an overall bias towards the lower antecedent remains, showing that the position of default focus is important in all sluices tested. The implications of these results for ellipsis processing and the relation between accent and focus will be discussed.

Life Expectancy for Protective Clothing
As the NFPA Technical Committee on firefighters protective clothing worked through the year 2008 revision of NFPA 1851, Standard on Selection, Care, and Maintenance of Protective Ensembles for Structural Fire Fighting and Proximity Fire Fighting, one of the most debated issues continued to be "What is the life expectancy of protective clothing?" Although the committee was not able to reach complete agreement on the answer to this question, there was consensus that structural ensemble elements should be retired ten years after the date of manufacture, and that proximity outer shells must be retired five years after the date of manufacture. However, the Annex does contain language explaining that this does not mean all ensemble elements will last or should remain in service for the full 5 or 10 years – just that five year old proximity outer shells and ten year old structural gear must be retired. The standard also provides additional criteria for inspection and retirement as well.
Having explained the mandatory requirements found in NFPA 1851, it is fairly well understood in the industry that the average life of a structural turnout suit is three to five years, and that proximity outer shells become worn out even sooner than that. It is important to remember, however, that average means some garments have lasted much longer and other garments not as long. Some segments of the fire service have even suggested that since the NFPA clothing standard is revised every five years, then five years should be the maximum time to leave garments in service. While this would ensure that as technology improves, garments would automatically be upgraded to meet new requirements and offer new levels of safety, it could leave the false impression that anything less than five years old is still perfectly compliant.
The reality is that the life span of any protective clothing is entirely dependent upon the type and amount of field use to which each separate garment has been exposed. Contributing factors to this include frequency of maintenance, storage conditions, exposures, and other issues that are beyond the garment manufacturer or material supplier's control. Facilities that specialize in care and cleaning will advise that they have seen clothing that is much older than five years and still in excellent shape; likewise, however, they have seen instances where the first time a garment was worn it was exposed to circumstances that totally destroyed the clothing. Since the purpose of firefighters clothing is to protect the wearer, if the gear has saved a life or prevented serious injury just once, then it has done its job.
It is also important to remember that protective clothing is a component system, not a single layer, and each component needs to be evaluated in its own right, with each layer routinely inspected for continued serviceability. For example, we have evaluated garments wherein the outer shell appears visually to be in excellent condition; however, closer inspection of the liner-moisture barrier will reveal rips or tears that would not be obvious in a cursory examination. Discoloration to any layer of the protective ensemble may be an indication that the garment is no longer able to provide the same level of protection as when it was new. Any discoloration should be carefully inspected.
The bottom line, regardless of when the clothing was produced, is that the safety officer or authority having jurisdiction must routinely perform an advanced inspection on all protective ensemble elements in order to assure that they are clean, maintained, and still safe. Just knowing the age of the gear cannot do that.

I have an array with a bunch of strings and I want to check if a certain string is contained in the array. If I use the containsObject: message on the array, I'm getting correct results. Do all NSString objects with the same string point to the same object? Or why is the containsObject: working?

Yes, hard-coded NSStrings (string literals) (that is any @"..." in your source code) are turned into strings that exist indefinitely while your process is running.
However NSArray's containsObject: methods calls isEqual: on its objects, hence even a dynamically created string such as [NSString stringWithFormat:@"%d", 2] would return YES in your sample snippet.
This is because NSString's isEqual: (or more precisely its isEqualToString:) method is implemented to be content aware (vs. comparing pointer identities) and thus returns YES for any pair of strings containing the very same sequence of characters (at time of comparison), no matter how and when they were created.
To check for equal (pointer-)identity you'd have to enumerate your array and compare via
NSString *yourString = @"foo";
BOOL identicalStringFound = NO;
for (NSString *someString in stringArray) {
 if (someString == yourString) {
 identicalStringFound = YES;
(which you most likely wouldn't want, though).
Or in a more convenient fashion:
BOOL identicalStringFound = [stringArray indexOfObjectIdenticalTo:someString]!= NSNotFound;
(you most likely wouldn't want this one either).
Summing up:
So the reason you're getting a positive reply from containsObject: is NOT because literal strings share the same constant instance, BUT because containsObject: by convention calls isEqual:, which is content aware.
You might want to read the (short) documentation for isEqual: from the NSObject protocol.
share|improve this answer
containsObject: performs a value check, not a pointer check. It uses the isEqual: method defined by NSObject and overridden by other objects for testing. Therefore, if two strings contain the same sequence of characters, they will be considered the same.
The distinction between pointer testing and value testing is very important in some cases. Constant strings defined in source code are combined by the compiler so that they are the same object. However, strings created dynamically are not the same object. Here is an example program which will demonstrate this:
int main(int argc, char **argv) {
 NSAutoreleasePool *p = [NSAutoreleasePool new];
 NSString *constantString = @"1";
 NSString *constantString2 = @"1";
 NSString *dynamicString = [NSString stringWithFormat:@"%i",1];
 NSArray *theArray = [NSArray arrayWithObject:constantString];
 if(constantString == constantString2) NSLog(@"constantString == constantString2");
 else NSLog(@"constantString!= constantString2");
 if(constantString == dynamicString) NSLog(@"constantString == dynamicString");
 else NSLog(@"constantString!= dynamicString");
 if([constantString isEqual:dynamicString]) NSLog(@"[constantString isEqual:dynamicString] == YES");
 else NSLog(@"[constantString isEqual:dynamicString] == NO");
 NSLog(@"theArray contains:\n\tconstantString: %i\n\tconstantString2: %i\n\tdynamicString: %i",

ThreatQuotient Launches Data-Driven Approach to SOAR and XDR, Accelerating Detection & Response
[May 04, 2021]
ThreatQuotient, a leading security operations platform innovator, today announced ThreatQ TDR Orchestrator, a new data-driven automation capability for more efficient and effective threat detection and response. This capability enables users to control what actions are to be taken, when, and why through the use of data.
"The security industry's approach to automation has overlooked the vastly different needs of detection and response use cases," said Leon Ward, VP of Product Management, ThreatQuotient. "The focus of ThreatQ TDR Orchestrator is data, not process. In detection and response, what is learned when performing an action is far more important than the action itself. ThreatQuotient has seized an opportunity to define and provide automation in a way that reduces complexity for security teams."
With the shortage of security personnel, automation has become a key strategy to offload repetitive tasks and empower humans to conduct advanced security operations tasks more efficiently. To date, automation has been looked at as defining a process and the steps needed to complete that process. This approach ignores the fact that automation is much more than just running the process. In reality, there are three important stages of automation to define and address:
 1. Initiate - Define what should have actions taken upon it and when those actions should occur
 2. Run - Perform the course of action or defined process through to completion
 3. Learn - Record what is learned for analytics and to improve future response
ThreatQ TDR Orchestrator puts the "smarts" in the platform and not the individual playbooks by using Smart Collections™ and data-driven playbooks. The application of Smart Collections and data-driven playbooks provides or simpler configuration and maintenance, and provides a more efficient automation outcome. This approach further addresses all three stages of automation - Initiate, Run and Learn - easily and efficiently by enabling users to curate and prioritize data upfront, automate only when relevant, and simplify actions taken. It can be used to complement other playbook capabilities through ThreatQuotient's ecosystem partners or users can define data-driven playbooks within the ThreatQ platform. To improve the platform "smarts", it will also capture what has been learned to improve data analytics, which in turn improves the initiation stage of automation.
Use cases for ThreatQ TDR Orchestrator include but are not limited to automating the following:
 - Hunting key threats as new intelligence is learned and recording the results
 - Deploying blocking and detection content to EDR and network devices
 - Enriching threat intelligence that meets complex criteria including relationships
 - Tasking a user to patch a high priority vulnerability that is being used in relevant campaigns
"Having high confidence in the data being used to trigger alerts is critical. ThreatQuotient's approach to security operations ensures that teams remain focused on high-priority threats through automation and optimization, achieving results such as freeing up multiple analysts for more important tasks," Ed Amoroso, CEO and Founder, TAG Cyber. "ThreatQuotient's data-driven approach to automation through ThreatQ TDR Orchestrator enables security teams to reduce the number of playbook runs and have confidence that the output is relevant and high priority."
ThreatQ TDR Orchestrator will be available in Summer 2021. To learn more about the benefits of data-driven automation, visit the ThreatQ TDR Orchestrator webpage.

A plan to save Prime Hook National Wildlife Refuge from rising sea levels may do more than just create new habitat for migratory birds, increase opportunities for hunters, and prevent flooding in some coastal communities.
The ambitious proposal, released by the U.S. Fish and Wildlife Service on May 31, may become a template for how Delaware deals with the coastal flooding that already strikes the state's many low-lying areas – a challenge that experts say will get far worse in coming decades.
The 10,000-acre Prime Hook preserve is one of the areas that state officials say will be virtually wiped out by the one-meter rise in ocean waters projected to happen by the end of the century if current trends continue.
Rising sea level is the main threat to the refuge and the main driver behind the federal agency's long-awaited Comprehensive Conservation Plan.
As salt water from the Delaware Bay inundates some 4,000 acres of what had been freshwater impoundments, those areas no longer attract the migratory birds that they were built to shelter. The surging waters from the bay frequently flood the adjacent community of Prime Hook Beach and damage bordering farmland with salt water.
The plan lays out three options for responding to repeated flooding at the refuge. The option favored by the Fish and Wildlife Service would raise the level of at least one of the impoundments by about seven inches by pumping in million of tons of sand and mud from a long-planned dredging project to deepen the Delaware ship channel. The agency hopes the operation will allow the area to revert to salt marsh and drain into the bay rather than drawing waters from it, as it does now.
"The bay is rising twice as fast as the marsh is," said Michael Stroeh, project leader for the Delaware Coastal Refuge Complex that includes Prime Hook and Bombay Hook refuges.
Stroeh said the Prime Hook plan could become a model for coastal restoration elsewhere because of its large size and because most other restoration projects, especially in the mid-Atlantic area, have not used dredging spoils to restore marshes.
"Any restoration project this large would be unique," he told DFM News. "It offers the opportunity for innovative ideas."
At a public meeting in Milford, Stroeh said the plan to dump dredging spoils at Prime Hook represents the best chance for the restoration project to succeed.
"The deepening project is my big shot to get sediment here," he told residents at the meeting.
If approved, work wouldn't begin until 2014 because the dredging spoils are earmarked for nearby Broadkill Beach and Kelly Island before that.
But the 102-mile dredging project — designed to give larger cargo ships access to Wilmington and other ports on the Delaware – faces legal challenges from environmentalists who say the plan would disrupt the ecology of the Delaware Bay. Seventeen miles of the channel near Claymont has already been deepened.
If the plaintiffs win their lawsuit against the project's leaders, the Army Corps of Engineers, that would halt work on the project, according to Jane Davenport, senior attorney for Delaware Riverkeeper Network, one of the environmental groups. The case is awaiting a ruling by the Third Circuit Court of Appeals in Philadelphia.
Davenport said any plan to dump dredging spoils at Prime Hook would be "extremely problematic" and would probably require the Army Corps to conduct another environmental impact statement before doing the work, a process that can take years.
Until the court rules, the Corps is pressing ahead and inviting bidders on the next phase of the project, according to Ed Voigt, a spokesman for the Corps in Philadelphia.
Voigt confirmed the Corps is talking to the federal wildlife service about using dredging spoils at Prime Hook. Any decision to take the material there would have to be funded by agencies other than the Corps, he said.
David Small, deputy secretary for Delaware's Department of Natural Resources and Environmental Control (DNREC), said the work at Prime Hook could have value well beyond the central Delaware coast.
"Could that be a model that could be followed in other areas?" he asked in an interview with DFM News. "I think it could be."
In April, DNREC released an assessment of Delaware's vulnerability to sea-level rise. It estimated that 10 percent or more of the state's land mass could be inundated by the end of the century. The agency's coastal team is now working on how the state should adapt.
For now, there's no immediate relief in sight for residents of Prime Hook Beach. They continue to endure frequent flooding of their yards, homes and streets as waters rush in to one of the impoundments on high tides, nor'easters, or major storms.
On June 4, a high tide flooded homes, ruined landscaping, and submerged Prime Hook Road, temporarily cutting off the community's main link with the rest of the state. "This flooding every few months is very difficult for the people who own these homes," said Cindy Miller, chair of the Prime Hook Beach Organization. "It's traumatic and it's a public safety issue."
Miller said the community needs immediate relief from the flooding rather than the long-term solution proposed by the federal Fish and Wildlife Service. Her group will offer more detailed comments at a June 19 public meeting to discuss the Prime Hook plan.
The federal agency says restoring the salt marsh alongside the community of some 200 homes should eventually reduce exposure to the ocean waters that now sweep into the impoundment through several dune breaches to the north.
For now, the agency proposes to put sand, coconut logs, and Christmas trees along the east side of the impoundment in hopes that will break up the waves. The agency says it has no plans to close the dune breaches, because winds and waves would probably undo the work quickly, as happened after a previous repair in 2011.
The federal Fish and Wildlife Service is expected to make a final decision on Prime Hook by the end of the year.

Whitehead's spiny rat description
Named after the British explorer John Whitehead who first documented its existence (3), Whitehead's spiny rat (Maxomys whiteheadi) has reddish-brown upperparts with grey underfur (2) (4). As its name suggests, Whitehead's spiny rat also has numerous inflexible grey spines with black tips on its upperparts, which are thought to be for protection. The underparts are orange-buff with grey underfur and numerous soft, pale spines (4) (5).
The tail, which is shorter than the head and body length combined, is bicoloured, with a brown-black upperside separated from a white underside by a sharp line (6).
Male Whitehead's spiny rats generally have longer hindfeet than females. This species of rat has the largest teeth of all Maxomys species. Six subspecies of Whitehead's spiny rat are currently recognised, all of which differ slightly in appearance (7).

Whitehead's spiny rat biology
Whitehead's spiny rat is believed to be monogamous, with each breeding pair occupying a home range that is defended against other spiny rats (8). It is believed to breed throughout the year, at least in peninsular Malaysia, and has one to six young per litter (5).
A nocturnal animal (8), Whitehead's spiny rat spends its nights foraging on the forest floor for a wide range of plant material, such as fallen fruits and seeds, with a preference for oil palm fruit (10). However, as an omnivorous species, its diet also includes arthropods (8). Like other spiny rats, it is a hoarder, storing seeds in deep underground burrows that are dug by other forest animals (11).
Whitehead's spiny rat is eaten by a number of predators, including the leopard cat (Prionailurus bengalensis) (9).Top
Whitehead's spiny rat range
Whitehead's spiny rat is native to Southeast Asia, ranging from peninsular Thailand south to Malaysia, Indonesia and Brunei. This includes the islands of Borneo and Sumatra, as well as various neighbouring islands (1).Top
Whitehead's spiny rat habitat
Belonging to a genus of rodents which are the most common in Southeast Asian tropical forests, Whitehead's spiny rat is found in old undisturbed areas of forest (8), as well as areas that have re-grown following a disturbance (secondary forest) (9). This ground-dwelling spiny rat also inhabits rice paddies and gardens adjacent to forests (8). Although generally a lowland species, Whitehead's spiny rat has been recorded at elevations as high as 2,100 metres on the slopes of Mount Kinabalu (1).Top
Whitehead's spiny rat status
Whitehead's spiny rat is classified as Vulnerable (VU) on the IUCN Red List (1).Top
Whitehead's spiny rat threats
The main threat to Whitehead's spiny rat is the widespread loss of habitat on Sumatra and Borneo (1), as a result of commercial logging and agriculture, particularly oil palm plantations (12). Lowland forests have been particularly hard hit, with some predicting that if this rate of deforestation continues, lowland forest in Sumatra and Kalimantan (Indonesian Borneo) may soon disappear completely (12).Top
Whitehead's spiny rat conservation
Although there are no known specific conservation measures currently in place for Whitehead's spiny rat, it occurs in the protected area of the Mount Kinabalu National Park, Borneo. A number of conservation organisations, such as WWF, are working to conserve forest in the region this endangered species inhabits (1) (13).Top

remote switching on and off of equipment. Wake-on-LAN/WAN is a technology that allows a computer to be turned on remotely by a software call. It can be implemented in both local area networks (LAN) and wide area networks (WAN). It has many uses, including turning on a Web/FTP server, remotely accessing files stored on a machine, telecommuting, and, in this case, turning on a computer even when the user####^~^~^~^~^~^####x2019;s computer is turned off. The Wake-On-LAN protocol defines a package called ####^~^~^~^~^~^####x201c;Magic Package####^~^~^~^~^~^####x201d; shown in Figure 3. This package contains the MAC address of the machine that is desired to switch on. The Magic Package is sent by the link data layer to all the NICs (Network Interface Controllers) using the address of the network diffusion. The frame is formed by 6####^~^~^~^~^~^####x2009;bytes (FF-FF-FF-FF-FF-FF) followed by 16 repetitions of 48####^~^~^~^~^~^####x2009;bits that represent the MAC address. The frame has 102####^~^~^~^~^~^####x2009;bytes in total.
This proximity detection prototype is integrated within an open MAS that includes all the agents and information needed to create an integral system for helping disabled people in the workplace.
Open MAS are systems in which the structure is able to change dynamically. Its components are not known a priori, change over time, and may be heterogeneous. The open MAS must allow the participation of heterogeneous agents with different architectures and even languages. This makes it difficult to rely on the agents####^~^~^~^~^~^####x2019; behavior and necessitates controls based on societal norms or rules. The open MAS was created using PANGEA.
3.1. Description of PANGEA
PANGEA is a service-oriented platform that allows the implemented open MAS to take maximum advantage of the distribution of resources. To this end, all services are implemented as Web services. Due to its service orientation, different tools modeled with agents that consume Web services can be integrated and operated from the platform, regardless of their physical location or implementation. This makes it possible for the platform to include both a service provider agent and a consumer agent, thus emulating client-server architecture. The provider agent (a general agent that provides a service) knows how to contact the Web service, while the remaining agents know how to contact with the provider agent due to their communication with the ServiceAgent, which contains information about services.
Once the client agent####^~^~^~^~^~^####x2019;s request has been received, the provider agent extracts the required parameters and establishes contact. Once received, the results are sent to the client agent. Using Web services also allows the platform to introduce the SOA (Service-Oriented Architecture) into MAS systems. SOA is an architectural style for building applications that use services available in a network such as the web. It promotes loose coupling between software components so that they can be reused. Applications in SOA are built based on services.
Using PANGEA, the platform will automatically launch the following agents.(i)####^~^~^~^~^~^####x2009;OrganizationManager: this agent is responsible for the actual management of organizations and suborganizations. It is responsible for verifying the entry and exit of agents and for assigning roles. To carry out these tasks, it works with the OrganizationAgent, which is a specialized version of this agent.(ii)####^~^~^~^~^~^####x2009;InformationAgent: this agent is responsible for accessing the database containing all pertinent system information.(iii)####^~^~^~^~^~^####x2009;ServiceAgent: this agent is responsible for recording and controlling the operation of services offered by the agents.(iv)####^~^~^~^~^~^####x2009;NormAgent: this agent ensures compliance with all the refined norms in the organization.(v)####^~^~^~^~^~^####x2009;CommunicationAgent: this agent is responsible for controlling communication among agents and for recording the interaction between agents and organizations.(vi)####^~^~^~^~^~^####x2009;Sniffer: it manages the message history and filters information by controlling communication initiated by queries.
The platform agents are implemented with Java, while the agents of the detection prototype are implemented in NET and nesC. These agents interact with the specific agents of the detection prototype; their interactions can be seen in Figure 4.(i)####^~^~^~^~^~^####x2009;ZigBeeManagerAgent: it manages communication and events and is deployed in the server machine. (ii)####^~^~^~^~^~^####x2009;UsersProfileAgent: it is responsible for managing user profiles and is also deployed in the server machine. (iii)####^~^~^~^~^~^####x2009;ClientComputerAgent: these are user agents located in the client computer. They are responsible for detecting the user####^~^~^~^~^~^####x2019;s presence with ZigBee technology and for sending the user####^~^~^~^~^~^####x2019;s identification to the ZigBeeManagerAgent. They manage the strength of the signal in order to determine how close or far away the user is. These agents are responsible for requesting the profile role adapted for the user to the ProfileManagerAgent when the user####^~^~^~^~^~^####x2019;s equipment needs to be turned on and personalized. Each ClientComputerAgent is located in a piece of office equipment (computer).(iv)####^~^~^~^~^~^####x2009;DatabaseAgent: the detection proximity system uses a database, which stores data related to the users, sensors, computer equipment and status, and user profiles. It can also communicate with the InformationAgent of PANGEA.(v)####^~^~^~^~^~^####x2009;ZigBeeCoordinatorAgent: it is included in the ZigBee device and is responsible for coordinating the other ZigBee devices in the office. (vi)####^~^~^~^~^~^####x2009;ZigBeeReaderAgent: these agents are included in several ZigBee devices that are used to detect the presence of a user. This agent is responsible for managing the personalized information for each user.
Every user in the proposed system carries a ZigBee tag, which is detected by a ZigBeeReaderAgent located in each system terminal and continuously in communication with the ClientComputerAgent. Thus, when a user tag is sufficiently close to a specific terminal (within a range defined according to the strength of the signal), the ZigBeeReaderAgent can detect the user tag and immediately send a message to the ClientComputerAgent. Next, this agent communicates the tag identification to the UsersProfileAgent, which consults the database to create the XML file that is returned to the ClientComputerAgent. The ClientComputerAgent then interacts with the ServiceAgent to invoke the Web services needed to personalize the computer according to the user####^~^~^~^~^~^####x2019;s profile.
Figure 5 presents a sequence diagram that shows the interaction between the agents involved in a case of user detection by the prototype. The note of the sequence diagram shows an example of XML used to identify the user profile.
4. Case Study
This paper presents a proximity detection system that is used by people with disabilities to facilitate their integration in the workplace. The main goal of the system is to detect the proximity of a person to a computer using ZigBee technology. This allows an individual to be identified and different actions to be performed on the computer, thus facilitating workplace integration: automatic switch on/off of the computer, identifying user profile, launching applications, and adapting the job to the specific needs of the user. As a result of the ZigBee technology, the prototype is notably superior to existing technologies using Bluetooth, infrareds, or radiofrequencies and is highly efficient with regard to detection and distance. Additionally, different types of situations in a work environment were taken into account, including nearby computers, shared computers as can be seen in Figure 6.
Our case study included a distribution of computers and laptops in a real office environment, separated by a distance of 2####^~^~^~^~^~^####x2009;meters. The activation zone is approximately 90####^~^~^~^~^~^####x2009;cm, a distance considered close enough to be able to initiate the activation process. It should be noted that there is a ####^~^~^~^~^~^####x201c;sensitive area####^~^~^~^~^~^####x201d; in which it is unknown exactly which computer should be switched on; this is because two computers in close proximity may impede the system####^~^~^~^~^~^####x2019;s efficiency from switching on the

Human-animal interaction encompasses any situation where there is interchange between human(s) and animal(s) at an individual or cultural level. These interactions are diverse and idiosyncratic, and may be fleeting or profound.
The human-animal bond is a mutually beneficial and dynamic relationship between people and animals that is influenced by behaviors considered essential to the health and well-being of both. The bond includes, but is not limited emotional, psychological, and physical interactions of people, animals, and the environment. The veterinarian's role in the human-animal bond is to maximize the potential of this relationship between people and animals and specifically to promote the health and well-being of both.
The AVMA officially recognizes: (1) the existence of the human-animal bond and its importance to client and community health, (2) that the human-animal bond has existed for thousands of years, and (3) that the human-animal bond has major significance for veterinary medicine, because, as veterinary medicine serves society, it fulfills both human and animal needs.

The study presents a brief review of Polish regions' participation in the global economy in 2011 based on exportlinkages at the local level (LAU 1). It identifies both the key actors in the globalisation processes withinthe country and the types of territories that share common trends in geographic and product export structures.The paper deals with a delimitation of areas of export concentration. A total of 23 areas have been identifiedaccounting for nearly 60% of Polish exports. Both the economic strength of the regions as reflected in theirrespective figures and the long-established position of industry in the national economy resulted in a widerange of areas discussed here.


In 2003, the drought-stricken state of Texas passed a law requiring retail public water utilities to conduct a water audit every five years.
"We needed to know water loss accountability, how much water loss there is, how the utilities report water losses, and how efficient they are in doing so," says Mark Mathis, municipal water specialist for the Texas Water Development Board.
Three years after the program was implemented, though, Mathis is hard-pressed to compare water loss volumes in the state. Each of its more than 3000 utilities had its own method for calculating water loss percentages, with different variables. Nothing was standardized. "It's so across the board," he says.
These inconsistencies will gradually disappear as utilities adopt the state's new water audit methodology. As part of the state mandate, the water board created an audit form and worksheet based on a newly formulated International Water Association (IWA)/American Water Works Association (AWWA) audit process. In an attempt to make utilities account for every single drop of water, the audit standardizes terminology in an industry where there are no hard-and-fast definitions.
"It's a new method that eliminates the percentage method of accounting, as well as the term 'unnaccounted-for' water, to show in more exact terms where the inefficiencies are occurring," says Mathis.
Although the board is non-regulatory, it can deny funding requests from utilities that haven't submitted a water audit. Mathis believes this stipulation will increase the number of local utilities that adopt the new methodology, so the board can better calculate and manage the state's water loss.
How do you report water loss? What factors do you use to calculate water loss percentages?
Chances are, if 100 water utilities are asked such questions, most won't agree on any given answer. For example, most utilities consider a 10% to 15% "unaccounted-for" water loss rate as acceptable. But what is "unaccounted-for" water loss?
"You can put 10 water utility managers in a room, ask them what 'unaccounted-for' is, and they will each have a different answer," says Mathis.
There also isn't a uniform method for determining water loss percentages, says Mathis. Plus, there are four key measures percentages don't reveal:
 - Where the losses are occurring
 - How much those losses are costing the utility
 - How much is being lost (expressed in volume)
 - Why the losses are occurring.

A worker at a McDonald's branch in Japan died of "karoshi" — the Japanese term for death from overwork — according to officials at the local government labor bureau. The employee, a 41-year-old woman, had put in about 80 hours a month in overtime for six months before she died. "We determined her work caused the illness," said an official at the agency.
The worker died in October 2007, after collapsing during a company training program. McDonald's Japan has yet to comment on the case, saying the company hadn't been contacted by authorities and needed to confirm the labor bureau's findings. In an earlier karoshi-related case, McDonald's paid a worker $75,000 in back overtime wages after his doctor warned him he was risking a stroke by working too hard.
The term "karoshi" is used by the Japanese government to refer to deaths — usually from heart attack or stroke — that are connected to excessive work. Approximately 150 workers die of karoshi each year, according to government data. Companies in Japan are increasingly being held liable for karoshi-related deaths and illnesses; earlier this year, a judge ruled that a man's suicide was due to his working conditions, and ordered his employer to pay $1.2 million to his surviving relatives.

In this case study I will be looking at one state, that is Punjab, and compare the differences of the population density between two districts, one rural and one urban, within that state, I will do this by looking at the birth rate, death rate fertility rate and infant mortality rate etc. And examining the fact and analysing them which led to the differences. In Jalandhar, the rural district, we see that the population is 1,962,700. In Amritsar, the urban district, the population is 3,096,077. The population is much larger in Amritsar, and we can say that Amritsar is a more urbanised area in Punjab.
This is because the government have spent much money to develop the area as it's a major city of tourism due to the location of the golden temple. This has also attracted both tourist and many people from rural areas. So the increase in population adds to the increase of population density in that area. In Jalandhar we see that as it's a rural district the population stays low therefore this plays one major role in leading to the low population density. Another point that I feel is correlated is that the people per household is proportionate to the number of population.
This is because as the area of the district is limited when there is an increase in the population the average space per person will decrease, this will lead to a rise in the people per household and therefore cause a higher population density. Now looking at Amritsar we can see that the number of people per households is 6, this is a high number is responsible by the high number of population, this number would have been higher if the area was low, but as it was high the number of people per household turned out quite less.
In Jalandhar we see that the number of people per household is 5, there not much different between Jalandhar and Amritsar this is because the area of Jalandhar is much smaller to that of Amritsar and this lead to an increase in the number of people per household. Therefore this proves our theory that as the population increases so does the people per household. So these factor effect the population density in a propionate way. I. E. if the population and number of people per household increases so does the population density.
Looking at the Birth rate and death rate, as the records were not found for each district I decided to use the different age group population and use the term 'high birth rate, low birth rate, high death rate, low death rate' according to how many people were in each age group. Now in Amritsar we see that the birth rate is quite high, this is because within the age group 0 – 4 we see that the population is 286,056. This tells us that the birth rate will be high and also the infant mortality rate will be quite low since the population of children is high.
Now looking at the rest of the age groups we see that the population is still quite high and this leads us to assuming that the death rate must be quite low as the population of the age groups does not decrease by a great amount. Also as we can see the number of people which live beyond 60 years is 283,409 this number is quite high and therefore we can say that the life expectancy is also high. To conclude this we can say as Amritsar is an urban city the medical facility is high and this is proved by the high number of population.
Drawn below is a sketch of the population pyramid of Amritsar from the assumed data written above. Now looking at Jalandhar we see that the population of people in the age group 0-4 is 154,749 this figure is much lower than what we saw in Amritsar. So therefore we can say that the birth rate is either low, this is unlikely as it is a rural district, or that the birth rate is high but the infant mortality rate is very high. In the other age groups we see that the population does not increase at an exponential rate and it is much lower than the figures in Amritsar, so this tells us that the death rate is high.
And also as there are relatively few people above the 60 year age group therefore meaning that the life expectancy is low. To conclude this we can say, as Jalandhar is a rural city the medical facility is low and this is proved by the low number of population as compared to Amritsar. These factors here also affect the population density again in a proportionate way. Drawn below is a sketch of the population pyramid of Jalandhar from the assumed data written above.
Now looking at both the population density of Amritsar and Jalandhar. We see that Amritsar has a population density of 619. 21. This is quite high but it's expected from an Urban district in a LEDC. Reason have been explained above, human and physical factors is listed below. In Jalandhar the population density is 577. 09 we can see this is lower than Amritsar's but still quite high, it is high because it is in a rural district region but it is lower than Amritsar's because jalandhar has a higher death rate.

Eccentric vs Concentric
Eccentric and Concentric are two words that are often confused in terms of their meanings and connotations. The two words are related to the contractions of the muscle. They are both types of isotonic contraction. When the muscle shortens to move a load then the muscle undergoes concentric contraction.
A bicep curl is one of the best examples of a concentric contraction. While holding a weight too, a man has to bend his elbow thereby, resulting in what is called concentric contraction. In other words, concentric contraction is all about muscular movement. The forearm gets pulled along with the weight in the case of concentric contraction.
The biceps brach would shorten its movement during the course of concentric contraction. Inefficient muscle use results in the other type of isotonic contraction called as the eccentric contraction. In short, it can be said that both concentric and eccentric type of muscle contraction is tried and practiced by the weight lifter during his workouts at the gym during body building exercises.
Hence, both these terms are associated with body building and weight lifting. If the muscle lengthens under contraction it amounts to eccentric contraction. Hence, eccentric contraction is exactly the opposite of concentric contraction. If the weight is too heavy to hold then the weight lifter feels that it is beginning to fall under control. This results in eccentric contraction.
It is important to note that the brachialis and biceps begin to contract trying to hold the extra weight. On the other hand, although the biceps try to hold the extra weight, they are unable to produce the extra force to hold the weight long, and hence, they give way resulting in eccentric contraction. These are the differences between the two words that are associated with body building and weight lifting, namely, eccentric and concentric.

The problem seams to be with float comparisons:

How else can we compare floats in ocaml?

Use =, not ==.
Floats are reference types in ocaml and == checks reference equality. So 0.1 == 0.1 is false.
Generally, you almost always want to use =, not == to compare two values.
Note that aside from that, your function will return true for two lists of different size. Assuming that's not intended you should only return true when both lists are empty and false when one of them is empty and the other is not.
As a style note, using List.length to check whether a list is empty is usually a bad idea (for one thing it's O(n) even though it can be done in O(1) with pattern matching). Using pattern matching right at the beginning will also clean your code up a bit.
Like this:
let rec compareVs v1 v2 = match v1, v2 with
| [], [] -> true
| [], _
| _, [] -> false
| x::xs, y::ys -> x = y && compareVs xs ys
Oh and if this isn't just an exercise, note that you can just do v1 = v2 and don't actually need to write a function for this.

I didn't know we could use, with match. Could you suggest any site where I can find all kinds of usages or examples of match or pattern-matching in general with OCAML? – lalli Oct 22 '10 at 15:32
_USER_: v1, v2 is a tuple and you can pattern match on tuples like on any other object. Also see this page for information about pattern matching. – sepp2k Oct 22 '10 at 15:36

Sepp2k is correct, but as an additional discussion about comparing floats (which is often dangerous), the following functions have helped me:
This compares two floats with tolerance of epsilon and the syntax would be similar to other float functions. clearly extending >. and others is obvious.
let epsilon = 1.0e-10
let (=.) a b = (abs_float (a-.b)) < epsilon
If you are dealing with many extreme values of floats, you should look at the classify_float function in the pervasives module. I don't recall off the top of my head how NAN values are compared in the = function. You can independently experiment with this if you need to.
I had used this for awhile, but its tolerance was actually way to low for my usage (as in, a very small value for epsilon as above). This does not take into account what, NAN - NAN does. So, this might not be useful.
 let (=.) a b = match classify_float ( a -. b ) with
 | FP_infinite | FP_nan | FP_normal -> false
 | FP_subnormal | FP_zero -> true

Utilizing measurements on a lanthano-aluminosilicate core optical fiber, the specific effects of lanthana (La2O3) on the Brillouin characteristics of silica-based oxide glass optical fibers are described. Lanthana is an interesting species to investigate since it possesses a wide transparency window covering the common fiber laser and telecom system wavelengths. As might be expected, it is found that the properties of lanthana are very similar to those of ytterbia (Yb2O3), namely, low acoustic velocity, wide Brillouin spectral width, and a negative photoelastic constant, with the latter two properties affording significant reductions to the Brillouin gain coefficient. However, lanthana possesses thermo-acoustic and strain-acoustic coefficients (acoustic velocity versus temperature or strain, TAC and SAC, respectively) with signs that are opposed to those of ytterbia. The lanthanoaluminosilicate (SAL) fiber utilized in this study is Brillouin-athermal (no dependence of the Brillouin frequency on temperature), but not atensic (is dependent upon the strain), which is believed to be, to the best of our knowledge, the first demonstration of such a glass fiber utilizing a compositional engineering approach.

The design principle of hotel bathroom
Regardless of which hotel or level, toilets are indispensable, but what size of toilet is appropriate? What are the main points of device placement? The editor below summarizes a few little knowledge about hotel bathrooms based on what I know. I hope I can help you much.
1. The bathroom has good waterproof, drainage, and slip resistance, and needs to be neat and beautiful;
2, 3 square meters is the minimum area of the bathroom, just now you can organize the sink, toilet and bathing equipment;
3. Nowadays, most of the floor of the hotel bathroom is paved with moisture-proof floor tiles. Its operation is relatively convenient. First, the cement floor is chiseled and washed, the floating ash is swept away, and a layer of 1:2 cement mortar is spread with some construction glue., The cement mortar should be smoothed as much as possible, and then the floor tiles can be attached;
4. When choosing sanitary ware for a bathroom with a size of 3 square meters, it is necessary to consider leaving a certain amount of space for activities. Washing tables and toilets are recommended to be delicate; the shower should be set close to the corner, and the shower can use a straight shower board or Simple shower. In addition, the bathroom mirror can be used to achieve the visual effect of expanding a small space;
5. Minimal objects should be placed in the bathroom as little as possible. A variety of small layouts will make the small bathroom more congested and messy. The shower method is more convenient than the bathtub. Generally, glass or shower curtains can be used to partition the corner of the bathroom as a shower room, but the shower room is not recommended. Less than 0.8m×0.8m, otherwise it is inconvenient to turn around. Bathrooms often have one or two walls without sanitary ware or other items. For this, you can choose a piece of furniture that can reasonably use the corner space according to the width of the wall, such as storage Cabinet, can store all the loose bathroom supplies in it. The mirror surface of the bathroom cabinet can be set on the storage cabinet, and the space under the basin can be used to make storage space;
6. When installing mirror headlights, pay attention to prevent glare. It is recommended to install lampshades, or choose lamps with frosted glass exterior. Mirror height: Generally, it is better to keep the center of the mirror 160-165 cm above the ground. The mirror in the bathroom is recommended to be framed. If it is not framed, it needs to be sealed and waterproof. When installing, be careful not to damage the wall, especially hang a mirror on the tiled wall, and try to choose to punch holes at the joints of the materials. In addition to installing ordinary mirrors, it is recommended to install a stretchable magnifying glass above the washbasin. When taking a bath, the mirror in the bathroom is vaguely smoked by the steam. You can apply soap to the mirror surface, and then wipe it with a dry cloth to prevent the mirror surface from being vague. The dirt on the mirror can be scrubbed with a soft cloth or gauze dipped in some kerosene or wax, but do not scrub with a wet cloth, otherwise the mirror surface will be blurred and the glass will be easily corroded.


Economic Policy Review Executive Summary
When the Back Office Moved to the Front Burner:
Settlement Fails in the Treasury Market after 9/11
Recapping an article from the November 2002 issue
Contact Authors
E-mail authors
23 pages / 251 kb
Authors: Michael J. Fleming and Kenneth D. Garbade
Index of executive summaries
Fleming and Garbade explain why a high rate of settlement fails persisted after September11 despite actions by the Federal Reserve and market participants to ameliorate the problems caused by the attack on the World Trade Center. They argue that fails rose initially as a result of the destruction of records and communication facilities, but remained high because the means typically used to avert or remedy fails—borrowing a security though a special collateral repurchase agreement—proved as costly as failing to deliver the security.
The magnitude of the settlement fails problem that arose in the aftermath of the attack was unprecedented in the history of the Treasury securities market and led Treasury to reopen the actively traded ten-year note with only two hours' notice to market participants. Both the size of the problem and Treasury's strong response make understanding the origins and context of the settlement fails problem particularly important.
Argument and Methodology
Fleming and Garbade begin their analysis with an overview of the settlement process in the Treasury securities market. They explain how settlement fails occur in the normal course of market functioning and describe the role of special collateral repurchase agreements in avoiding and remedying fails (exhibit).
The authors then describe the initial effects of the September11 attack on the settlement process. The destruction of trade records, brokers' offices, and communication facilities caused settlement fails to soar. For the week ending September19, fails averaged $190billion per day, far exceeding the $7.3billion daily average for the first eight months of 2001 (chart). The Federal Reserve responded quickly by suspending selected limits on its securities lending program, thereby making collateral more readily available to primary dealers. Concurrently, market participants worked to resolve the communication and operational problems caused by the attack.
Fleming and Garbade go on to show that despite these steps, settlement fails continued at a high rate through the end of September. The authors argue that fails remained high because a relatively low federal funds rate and investor reluctance to lend securities kept the rates on special collateral repurchase agreements at or near zero. With such low "specials" rates, investors had little incentive to borrow the securities they needed to settle earlier trades.
As concern grew that the level of fails was undermining market functioning, Treasury officials took the unprecedented action of reopening the ten-year note with only two hours' notice. The additional supply raised the note's specials rate and increased investors' incentives to settle their trades. Thereafter, fails declined quickly, dropping from a daily average of $142billion during the week ending October3 to $63billion per day the next week, and then to roughly $18billion per day in each of the following two weeks (chart).
The authors attribute the persistence of fails following September11 to specials rates that were near zero for several actively traded securities. In effect, the cost of borrowing securities to avert or remedy a fail during this period was virtually as high as the cost of failing. Treasury's action to reopen the ten-year note raised the specials rate and made borrowing the note more attractive than failing.
Fleming and Garbade conclude their analysis with a look at long-run reforms to alleviate chronic fails. One initiative considered is the creation of a Treasury facility that could lend specific securities on a temporary basis during periods of high demand. Chronic fails could also be reduced, the authors suggest, through the institution of a penalty fee for fails.
Fails may be remedied by borrowing the needed security through a special collateral repurchase agreement. In the second section of the exhibit below, B remedies its fail to investorC by "reversing in" bonds from investorD and delivering the borrowed bonds to C.
Borrowing Securities to Cure a Settlement Fail
Settlement fails reached their peak immediately after the September attacks and remained high until early October, when Treasury reopened the on-the-run ten-year note.

A new study on the Irish electricity system has revealed that the growing levels of wind generation on the Irish electricity network are not adding to the wholesale price of electricity. The report by grid operator EirGrid and the Sustainable Energy Authority of Ireland, uses detailed modelling tools to look in detail at the wholesale prices in the Irish electricity system in 2011, which has a total annual value of almost €2 billion
The analysis showed that wind generation lowers wholesale prices by over €70 million, which almost exactly offsets the costs of the Public Service Obligation (PSO) levy and other costs associated with the generation of wind energy. The study clearly demonstrates that wind energy is not contributing to higher wholesale electricity prices on the Irish electricity system.
Wind generators have high capital costs, but as they do not consume fuel they have no short-term costs. By displacing higher cost fossil fuel generation, wind energy tends to reduce the wholesale cost of producing electricity, the study has found. When balanced against other costs, the overall cost impact of wind is less than half of one percent, which is within the study's margin of error.
The increased use of wind energy on the Irish electricity system increases Ireland's security of supply and ensures a more diverse fuel supply in the long-term.
Dermot Byrne, chief executive of EirGrid, says: "Reliable, economic and sustainable power is crucial to Ireland's future. Renewable energy can play an important part in the energy mix but it is important to continuously look at the effect on prices of all sources of energy, in the interest of consumers. This report is a significant contribution to that."
Dr Brian Motherway, chief operations officer of SEAI.
Dr Brian Motherway, chief operations officer of SEAI, remarks: "It is important that our energy debates are based on solid facts and clear evidence. This detailed analysis answers an important question – that exploiting our strong wind energy resource comes at no additional cost. It is right that we keep a focus on energy costs, and it is very good news to see that we can capture the benefits of wind energy without having to pay extra for them. And as fossil fuel prices increase the economic benefits become more significant."
IWEA (Irish Wind energy Association) has today welcomed the publication of the Eirgrid/Sustainable Energy Authority of Ireland study. "The report is further proof that Ireland's most abundant and environmentally friendly natural energy resource, wind, can be harvested without any additional cost to the consumer," comments Dr Michael Walsh, chief executive of IWEA. "The study, we anticipate, will be supported by the findings of our own comprehensive report, titled 'The Impact of Wind on Pricing Within the Single Electricity Market', which will be published on March 1st. This report, which was conducted by international specialist energy consultancy Redpoint, follows an in-depth analysis of the impact that wind generation has on two components of consumer bills; electricity prices and renewable support."

About the webinar
The webinar will present key new trends and data emerging from the 27 countries, including three new country profiles on Albania, Croatia, and Ireland. 2020 has seen positive steps towards new statelessness determination procedures, 1954 Convention reservations withdrawn, and measures to address barriers to birth registration. But the Index highlights that much remains to be done to bring law, policy, and practice in line with States' international obligations.
After the state of play update, a panel of invited experts will then offer their reflections on what the trends identified mean for stateless communities, national governments, regional institutions and other stakeholders and how we can better work together to ensure stateless people are not left behind in our complex and challenging times.
About the issue
A stateless person is someone who has no nationality, someone who is not recognised as a national by any State. Statelessness affects over half a million people in Europe – both people on the move and those who have lived in the same place for generations – denying many their fundamental rights. Its causes include state succession, gaps in nationality laws, discrimination, displacement, and nationality stripping.
Despite the extent of the problem, many states still lack robust policies to address statelessness. Critically, only a handful of countries in Europe have a dedicated statelessness determination procedure to identify people on their territory without a nationality and to offer appropriate protection status (including residence and other rights under the 1954 Convention) and subsequent naturalisation. Accessing regularisation routes and protection can be more difficult for stateless people due to their marginalisation and lack of documentation. Stateless refugees and migrants are often wrongly assigned a nationality or recorded as having 'unknown' nationality. The result can be a failure to identify (and prevent) the risk of statelessness among children born in exile, or barriers to protection, family reunification and naturalisation. A stateless person with no right to residence often has no country they can return to, so if their statelessness is not identified, they can face repeated, futile removal attempts and prolonged detention.


Haris Ahmed Chicago Consultant: Top 3 Benefits of Job Rotation
For Haris Ahmed of Chicago-based management consulting firm Pragmatium Consulting, Inc., employees are the heart of every business. Each one plays a crucial role in the organization, and as such, each one deserves equal opportunities and privileges. But despite the company's best efforts, there will always be employees who are underperforming or not living up to their full potential—for whatever reason (professional or personal). How do you encourage your employees to always give their best to whatever task needs to be done? How do you help them establish strong bonds with one another?
In this post, Haris Ahmed, Chicago management consultant and change expert, shares with readers what a job rotation is and the benefits to be derived from it.
What is job rotation?
In simple terms, job rotation is an internal strategy where the organizational structure is reshuffled to encourage employee growth and retention. This strategy is often initiated by the Human Resources department of the organization, discussed with team or department heads, and approved by the CEO and other top executives.
Usually, an employee is assigned to another department or given a new position because this is where their talents and skills will truly be of value to the organization, and where they have more opportunities for growth. When an employee has been with the company for years, he or she may have acquired or developed new skills, and assigning them to a new department with new responsibilities is the best way for them to further hone their newly acquired skills.
Here are the top 3 benefits of organizational restructuring and job rotation:
1. Improve performance and productivity. As mentioned above, when you assign an employee to a new team and give him or her new responsibilities, you allow the employee to grow. New challenges mean new opportunities and with these come a rejuvenated spirit, which could mean improved performance and productivity. This, in effect, targets the employee's performance and productivity, and the department's or team's.
2. Encourage loyalty. When an employee feels that he or she has become 'stagnant' or feels more like a wallflower than an active participant within the organization, chances are they will eventually leave and go where they are appreciated—where they would be made to feel that their contributions are valuable to the organization. Job rotation prevents this from happening, for reasons stated above.
3. You create a dynamic organization. When people learn of the organization's active participation in their employees' growth and advancement, they will see your company as a potential employer, upping your reputation as a good organization to work with. When you have positions that need to be filled, applicants wouldn't hesitate to join your organization because they know there is room for growth.
In his next post, Haris Ahmed will share his recommendations on how to approach job rotation and make employees understand that this is a step towards their own growth and advancement.

Does the Laplace equation on a rectangle with Dirichlet boundary conditions at two opposing sides and Neumann boundary conditions at the other two, always have a solution? If it does, is it unique? Is the same true for the discrete Laplace equation (with the standard five-point laplacian)?
share|improve this question
3 Answers 3
The solution to the Dirichlet problem is unique by the maximum principle. For the same reason, the solution to the Neumann problem is unique up to a constant.
At worst your problem would fail uniqueness by a constant, but those Dirichlet conditions you've got will prevent this.
This carries over to the discrete case. But note that the discrete case is an easier problem since you can just write out the matrix you need to invert and check if it's invertible.
share|improve this answer
I am not familiar with the discrete case. As for continuous case, I think you can use the method of images to solve this problem. It should always have a solution and it should be unique, due to the fact that the underlying Green's function is unique. In particular, to construct the Green's function, after reflecting by a Neumann or Dirichlet boundary, you put a same (resp. opposite) source (Delta function). By this way, we have an infinitely many sources, then your Green's function is the sum of the effects by all the sources. Hope it can help. :-)

Lining Extrusion and Cracking
Lining extrusion and cracking may be caused by overheating, which can reduce the strength of linings so that the material yields and cracks from the effect of normal and shear forces transmitted through very thin oil films. Wiping does not necessarily occur under such conditions.
Addressing the Damage
Fit new or reconditioned bearing pads. To prevent future damage, investigate and, if possible, reduce the maximum operating temperatures.

Brush Lettering
Hey guys! It's me again.
Want to start brush lettering but don't know how? If you haven't done Faux Calligraphy, go ahead and check out the post. To do either, you need a rudimentary knowledge of cursive. If you don't know how, I recommend using the D'Nealian or the Spencerian Method. I did the the D'Nealian method and now I doing the Spencerian method which is great!
To brush letter, you'll need: paper, a brush pen (best brush pen to start with is Tombow Fudenoske (comes in hard and soft tip)). I'm using normal printer paper and (what brush)
Step 1. Remember upstrokes and down-strokes? (insert photo) Practice thick down-strokes and thin upstrokes. Don't be afraid to push down on the brush tip. 🎨
Step 2. Let's do the letter "a," a cursive letter "a."
Remember to achieve downstrokes and maintain your marker, hold the tip at a 45 degree angle to the paper.
Step 3. Practice is the key to mastery (maybe I heard it somewhere 😊)
PRACTICE is the only advice I can give to getting better. I started brush lettering maybe a year and half ago.
Tell how you did!! and practice!
