T h e intent would be to reduce or delay the nematode populat ion build-up until an acceptable yield was assured, as is usual with toxic nonfumigant nematicides. An added benefit of nematode control with amino acids is the human nutr i t ional value of any residual material. Furthermore, these findings clearly establish the feasibility of alternative chemotherapy as a practical, safe means of m...

one of the fundamental issues in the ethics of medical researches is cost-benefit assessment which consists a main part of related codes. this article is aimed to propose a model for ethical assessment of researches with judgment about their costs and benefits. after reviewing related materials and our experiences and discussions with experts, we proposed a model for ethical assessment of costs...

background and aims: the safe, potent and effective live vaccines against measles, mumps and rubella as important childhood diseases have been available for several decades. several factors can affect the thermal stability of lyophilized vaccine. methods: in this study, the effect of residual moisture on thermal stability of 61 batches of mmr vaccine was investigated using an accelerated method...

In the treatment of cancer the fundamental surgical goal is to remove all local malignant disease and leave no residual malignant cells. Studies have demonstrated the benefit of achieving negative resection margins in terms of disease free local recurrence and overall survival. The surgical margins for Head & Neck cancer may vary widely depending on the site of disease. This variation reflects ...

In this paper we study some monotone behavior of the residual (past) entropy of order . We prove that, under some relation between the hazard rates (reversed hazard rates) of two distributions functions F and G, when the residual (past) entropy of order of F is decreasing (increasing) then the residual (past) entropy of G is decreasing (increasing). Using this, several conclusions regarding mo...

the parallel systems are special important types of coherent structures and have many applications in various areas.in this paper we consider a two-exchangeable-component parallel system for the generalized farlie-gumbel-morgenstern (generalized fgm) distribution. we study the reliability properties of the residual lifetime of the system under the condition that both components of the system ar...

abstract background: the current practice to measure rv is either by bpg or helium dilution methods which may not be available in all clinics due to their cost. methods: this paper outlines a method for both direct and indirect calculation of rv via pft with acceptable sensitivity (81 %, 60% ), specificity (71 %, 94%) and validity (76%, 78%) for obstructive and restrictive lung disease respecti...

in the present health care environment, cost-benefit analysis is extremely important. in this screening program, the minimal cost of screening dipstick urinalysis in 1601 asymptomatic school children was determined. the process of screening was similar to all the studies. the minimal cost utilizing 3 general physicians was calculated. costs were determined by using current charge for supplies o...
