A 2.0% zinc phosphide pellet and a 0.001% brodifacoum bait gave the lowest percentage post-treatment activity in a field test in which broadcast applications were followed shortly by rain. There was not a clear difference in performance between the single-feeding toxicants and the multiple-feeding anticoagulants in this experiment. A 0.075% cholecalciferol bait gave control comparable to some r...

Epitaxial layers of p-type indium phosphide (InP) have been grown by low pressure, metal organic chemical vapour deposition (LP-MOCVD) using diethylzinc (DEZn) as the p-dopant source. Proposed zinc-associated InP point defects and experimental DEZn doping data were used to formulate a point-defect equilibrium model of the Zn doping process of MOCVD InP. The model equation is contrasted with the...

This prospective study was aimed to analyze the nature of and the factors associated with deliberate self-poisoning in children below the age of 12 years. Children referred to the Child Guidance Clinic for evaluation after recovery from the effects of poisoning during the five-year period between 1999 and 2003 formed the subjects of the study. The children were evaluated for stress factors, psy...

Rodents are a major constraint to forage production for livestock in Mongolia. A technical program to identify the magnitude of the problem and strengthen the research capabilities of Mongolian rodent specialists was initiated in 1994. The Brandt's vole is the most widespread and the most detrimental rodent to the steppes of Mongolia. Limited resources inhibit activities by the Mongolian Plant ...

Rodents cause substantial amounts of damage and losses of foodstuffs around the world. While various methods are used to reduce damage and losses to rodents, rodenticides remain the most important tool in the toolbox. However, like all tools, rodenticides have advantages and disadvantages. Several considerations are shaping the future of rodenticide use. These include manufacturing and registra...

The optical transparency and high electron mobility of graphene make it an attractive material for photovoltaics. We present a field-effect solar cell using graphene to form a tunable junction barrier with an Earth-abundant and low cost zinc phosphide (Zn3P2) thin-film light absorber. Adding a semitransparent top electrostatic gate allows for tuning of the graphene Fermi level and hence the ene...

Shrew is an animal belong to small mammals that the existence must be noticed because it has defecation behavior and their droplets often pollutes house. can vectors in spread of infectious diseases human. management not been conducted well. Information about most preferred bait effective rodenticide as a reference controlling widely known. Chemical control using rodenticides enough does take l...
