All governors have some sort of safety shutdown mechanism to operate automatically or
manually to close the wicket gates in case of emergency. The device is usually controlled by a
solenoid. In most cases, a weighted arm that is connected to the gate limit mechanism is held in
place by the solenoid. If the trip is initiated, either automatically or manually, the solenoid is de-
energized, dropping the weight, causing the gate limit to go to zero. A few installations have
shutdown solenoids that are designed so that they must be energized to trip. Typically, there...
Performance evaluation measures the skill of an asset manager and its principal idea
is to compare the returns with an alternative appropriate portfolio to that which was obtained
in a particular case. The emergence of modern portfolio theory (MPT) by Markowitz (1952),
who quantifies how rational investors make decisions based on expected return and risk, has
brought much development to portfolio performance measurement.
Food technology and safety research financed by the European Commission
has the obvious objective of enhancing the quality of life, in the short term as
well as in a long-term perspective. Research as such is most often seen as a
long-term activity and even the most applied research should be regarded as
an investment for future benefits. Nevertheless, the EU should address
research on short-term issues, in order to meet the needs of rapid and
accurate information in cases of emerging transnational crises. ...

Abstract Biliary stones are usually found in the gallbladder, but about 10-20% may spontaneously migrate into the common bile duct where they either remain trapped or migrate subsequently via the papilla of Vater into the duodenal lumen. In some cases, biliary stones may form de novo in the common bile duct because of local precipitating factors.

A unique cause of hemoperitoneum: spontaneous rupture of a splenic hemangiopericytoma
Picozzi Stefano Carlo Maria1*, Massimo Mauri2 and Luca Carmignani1
Abstract Non-traumatic hemoperitoneum may be catastrophic if it is not promptly diagnosed and treated. It is critical to identify this clinical picture and treat any active bleeding.

Massive acute colonic pseudo-obstruction successfully managed with conservative therapy in a patient with cerebral palsy
Derek R Cooney* and Norma L Cooney
Abstract Acute colonic pseudo-obstruction (ACPO), also known as Ogilvie syndrome, is a massive dilation of the colon in the absence of mechanical obstruction.
The Wiley Series in the Psychology of Crime, Policing and Law publishes single
author and edited reviews of emerging areas of contemporary research.
The purpose of this series is not merely to present research findings in a clear
and readable form, but also to bring out their implications for both practice
and policy. The series will be useful not only to psychologists, but also to all
those concerned with crime detection and prevention, policing and the judicial

While various glomerular disorders account for the most cases of end stage renal
failure, the etio-pathogenesis of these conditions intrigued many investigators for
decades. A clear knowledge of the etiology and pathogenesis is crucial for developing
novel strategies to prevent and to treat these disorders. Notwithstanding the
continuous emergence of new discoveries, we still have a long way to get any closer to
a thorough understanding of the mechanisms of glomerular injury.
The study of how biodiversity is spread around the world is known as bio-
geography. Mite harvestmen illustrate one of the most common patterns in bio-
geography, called vicariance: species become separated from each other when
geographical barriers emerge. Those barriers can be formed by oceans, as in the
case of the mite harvestmen; they can also be separated by rising mountains,
spreading deserts, and shifting rivers. The other major pattern in biogeography,
known as dispersal, occurs when species themselves spread away from their
place of origin.
Tuberculosis (TB) kills more than 4,500 people each day worldwide;
approximately 1.7 million TB deaths occurred in 2006 alone (WHO,
2008a). TB is second only to AIDS as the leading infectious disease–related
cause of adult deaths. Although antibiotic treatment for TB was discovered
more than half a century ago, an estimated one-third of the world’s popula-
tion is currently infected with Mycobacterium tuberculosis (Keshavjee and
Seung, 2008), and 9.2 million new cases of active TB are estimated to occur
around the world annually (WHO, 2008a). ...
In terms of numbers also, in roughly half of the companies, promoters have a
majority stake. The incidence of majority promoter ownership is more prevalent in
case of large companies with more than Rs. 50 crores market capitalisation (Table-
VI). Promoter’s stake, however, need not always be held by the promoters
themselves in their personal capacity. It could be provided by other companies
controlled by the group, some of which could be listed companies themselves.
The ability to recognize and deal with complex business ethics issues has become a
significant priority in twenty-first-century companies. In recent years, a number of
well-publicized scandals resulted in public outrage about deception and fraud in
business and a demand for improved business ethics and greater corporate responsibility.

Fisher and Mahalanobis described Statistics as the key technology of the twentieth century. Since then Statistics has evolved into a ﬁeld that has many applications in all sciences and areas of technology, as well as in most areas of decision making such as in health care, business, federal statistics and legal proceedings. Applications in statistics such as inference for Causal effects, inferences about the spatio- temporal processes, analysis of categorical and survival data sets and countless other functions play an essential role in the present day world.
(BQ) The aim of the 100 Cases series is to provide a novel learning and revision tool that works by guiding the reader through clinical cases, imitating those that students and junior doctors are likely to meet in accident and emergency and outpatient departments, and in general practice.
All have been, more or less, a response to three chronic problems: U.S. schools fare badly in international comparisons, the school dropout rate is high and probably rising, and a huge gap in achievement between whites and blacks (with Hispanics in the middle on most measures) emerges as early as age three...
