abstract the main aim of the paper is to determine the marketing efficiency of poultry industry in karaj. in this research the marketing margin and the marketing efficiency of poultry market in different level of the market in karaj was calculated. the results showed that slaughter houses gain the main part of marketing margin and marking profit. the share of slaughter house was more that 50 pe...

BACKGROUND Since the last In-Depth Review of lead toxicity in 2004 there have been further developments with regard to safe exposure levels for lead workers. AIMS To advise occupational health professionals of the latest research on the multi-system toxic effects of lead and the implications of this research for setting new safe and appropriate occupational suspension limits. METHODS An ext...

Previously, a computer-based navigation system has not been used routinely for en-bloc resection of sacral tumors. In order to improve the accuracy of tumor resection, O-arm navigation was used to join anterior and posterior osteotomies during an en-bloc resection of a sacral Ewing's sarcoma. This case study describes the technique for en-bloc resection of a sacral Ewing's sarcoma guided by O-a...

Consistent stochastic orders of processing times and objective functions yield optimal policies in many stochastic scheduling problems. When these orders fail to hold, however, finding optimal values may be difficult. In this paper, we show how to bound these values in general situations including problems with unreliable machines and tardiness-based objectives.

A REGIMENTED PROGRAM OF RESISTANCE TRAINING CAN PROVIDE A MULTITUDE OF BENEFITS FOR THE PREGNANT WOMAN. HOWEVER, A WOMAN UNDERGOES SIGNIFICANT PHYSIOLOGICAL AND MORPHOLOGICAL CHANGES THROUGHOUT THE TERM, AND THESE ISSUES NEED TO BE TAKEN INTO ACCOUNT WHEN DESIGNING A ROUTINE. THEREFORE, THE PURPOSE OF THIS PAPER WILL BE 3-FOLD: (A) REVIEW THE BENEFITS OF MATERNAL RESISTANCE EXERCISE, (B) DISCUS...

In our daily lives, the advances of new technology can be used to sustain development for people across the globe. Particularly, e-government can be the dynamo of the development for the people. E-government services are intended to be responsive, citizen-centric based and social inclusive. It also engages citizen to participate in the process of delivery of services. Consequently, users can ea...

Railway interlockings are dominated by highly proprietary systems. We present the development project Alister 2.0 – an interlocking system based on industry-proven standard components: Safety PLCs in distributed nodes communicate over safe network protocols. This enables a highly productive and highly maintainable fail-safe interlocking system for centralised traffic control.

Current statistical models for structured prediction make simplifying assumptions about the underlying output graph structure, such as assuming a low-order Markov chain, because exact inference becomes intractable as the tree-width of the underlying graph increases. Approximate inference algorithms, on the other hand, force one to trade off representational power with computational efficiency. ...

BACKGROUND This study sought to determine safe ranges of oblique angle, skin entry point and needle length by reviewing computed tomography (CT) scans and to evaluate the usefulness of a bent tip needle during celiac plexus block (CPB). METHODS CT scans of 60 CPB patients were reviewed. Image of the uppermost margin of L2 vertebral body was used to measure the minimal and maximal oblique angl...

OBJECTIVE To define the anatomic "safe zone" for placement of external fixator half pins into the anterior and lateral femur. METHODS In 20 fresh-frozen hemipelvis specimens, the femoral nerve and all branches crossing the femur were dissected out to their final muscular locations. The location where the nerves crossed the anterior femur was measured from the anterior superior iliac spine and...
