Forest environment classification in mountain regions based on single-sensor remote sensing approaches is hindered by forest complexity and topographic effects. Temperate broadleaf forests in western Asia such as the Hyrcanian forest in northern Iran have already suffered from intense anthropogenic activities. In those regions, forests mainly extend in rough terrain and comprise different stand...

Public concern over increasing health-care costs plus dramatized testing errors, has resulted in CLIA '88 with its more stringent rules governing laboratory performance. The purpose of the 1990 U.S. Health Care Financing Administration Final Rules for Proficiency Tests is to separate the quality laboratory from the poorly performing one. From the perspective of total quality management, the cus...

Simulation of crop systems has evolved from a neophyte science into a robust and increasingly accepted discipline. Our vision is that crop systems simulation can serve important roles in agriculture and environment. Important roles and uses of crop systems simulation are in five primary areas: (1) basic research synthesis and integration, where simulation is used to synthesize our understanding...

We show genetic improvement of programs (GIP) can scale by evolving increased performance in a widely-used and highly complex 50 000 line system. GISMOE found code that is 70 times faster (on average) and yet is at least as good functionally. Indeed it even gives a small semantic gain.

Aquaculture in developing countries is largely based on unimproved fish strains. There is ample evidence indicating the potential of genetic improvement programs and a range of selection methods may be used. Examples of the application of mass, cohort, within family, and combined between-within family are given. The methods are discussed in terms of their effectiveness and suitability. It is co...

AIMS To identify the prognostic variables concerning the improvement of overactive bladder syndrome (OAB) related symptoms following a transurethral resection of the prostate (TURP) in patients with benign prostatic obstruction (BPO). METHODS A retrospective review was conducted in 298 patients with BPO who had undergone TURP. All patients had completed the preoperative evaluations including ...

introduction atrial standstill is a rare condition, characterized by absence of atrial electrical and mechanical activity evident in surface electrocardiography echocardiography, or fluoroscopy, which is associated with unresponsiveness of atria to maximal output electrical stimulation. this condition can be present with thromboembolic complication, low cardiac output, and sometimes palpitation...

stand establishment in crusting soil is one of the main concerns in the production of crops with delicate seedlings such as cotton, onions and rape seed. crust breaking, maintaining soil moisture and adding chemical and organic amendments to soil are different methods to weaken soil strength and allow the shoots to emerge. these methods are not always successful because they depend on factors s...

Poor emergence resulting in inadequate stand establishment is a major problem associated with direct-seeded rice production, especially for semidwarf cultivars. In order to gain information on the problem, plant type related to gibberellic acid (GA3) and seeding depth was studied. A total of 21 cultivars including 9 semidwarfs and 12 talls had seed treated with GA3 at 25 parts per million (ppm)...

Thinning treatment is a necessary and complex forestry activity. The experimental results from plantations established 20-30 years ago explains some concepts of the theory, practice, methods, regime thinning on permanent sample plots pine stands in Gatchinsky Leningrad region were shown this article. Choosing right method allows to optimize yield, productivity mortality stand. On other hand, we...
