Magnesium is the lightest of all the metals and the sixth most abundant on Earth. Magnesium is ductile and the most machinable of all the metals. Magnesium alloy developments have traditionally been driven by requirements for lightweight materials to operate under increasingly demanding conditions (magnesium alloy castings, wrought products, powder metallurgy components, office equipment, nuclear applications, flares, sacrificial anodes for the protection of other metals, flash photography and tools). The biggest potential market for magnesium alloys is in the automotive industry. ...
This study combines the discussions of the main impacts on the European
food sector (food crises, technology progress, globalisation) with a forward
looking exercise. As a result, key categories for future research in the
European food sector are outlined, and potential research priorities are
The distrust of consumers towards policy makers and food industry in the
wake of several severe food scandals obviously had a strong influence on
scientists and experts linked to the present study.
Weight loss procedures are being performed more frequently to treat morbid obesity, with a
six-fold increase over a recent 7-year time span; almost half of patients are women of
reproductive age. The level of evidence on fertility, contraception, and pregnancy outcomes is
limited primarily to case series and case reports. The evidence suggests that fertility improves
after bariatric surgical procedures; however, data are too sparse to reach definite conclusions
about the degree of improvement in fertility that is achieved.
Defined in this way, a strategic communications audit has both evaluative and formative
value. It is evaluative in that it provides a “snapshot” of where an organization currently
stands in terms of its communication capacity or performance. It is formative in that it
also points to areas in which the organization can strengthen its performance.
Communications audits are a relatively common practice, though they are more
common among for-profits than nonprofits, and not familiar to most non-
This program focuses on farmlands located in Southern Thailand. ORRAF
supports the initial budget to cover costs of clear felling, site preparation,
seedlings, fertilizers, weeding and labour. The budget for the initial costs is
7300 baths per rai for a 7-year period, that is, until the farmer is allowed to
conduct the first rubber tapping activities. Full payment of benefits is
delivered to the small-scale farmer in seven instalments. The extension
officers perform yearly auditing visits to the farmland sites in order to verify the
proper use of funds.
An organized system of follow-up is important for all device patients and is best facilitated through the patient's membership in a formal pacemaker/ICD follow-up clinic. The first formal clinic follow-up visit is usually scheduled at approximately 3 months after implantation to allow for completion of the lead-tissue maturation process, which may affect sensing and capture thresholds. Reprogramming, to account for any threshold change since implant, and still provide a safety margin along with improved battery life, may be done at that time.
Brachytherapy is the direct implantation of radioactive sources into the prostate. It is based on the principle that the deposition of radiation energy in tissues decreases as a function of the square of the distance from the source (Chap. 81). The goal is to deliver intensive irradiation to the prostate, minimizing the exposure of the surrounding tissues. The current standard technique achieves a more homogeneous dose distribution by placing seeds according to a customized template based on CT and ultrasonographic assessment of the tumor and computer-optimized dosimetry.

The effect of abductor muscle and anterior-posterior hip contact load simulation on the in-vitro primary stability of a cementless hip stem

Abstract Background: In-vitro mechanical tests are commonly performed to assess pre-clinically the effect of implant design on the stability of hip endoprostheses.
The pioneering work of Bra˚ nemark ushered in a new era in dentistryd
the era of implant dentistry. Bra˚ nemark and his colleagues created a new
field of study from a serendipitous research observation, thus exemplifying
Pasteur’s dictum that ‘‘chance favors the prepared mind.’’ Through further
research, these investigators transformed the field of implantology from an
unpredictable art to a well-grounded clinical science. This research provided
the scientific basis for a set of strict clinical protocols.
