This project is aimed at studying environmental pollution using ion-beam analysis (IBA) techniques. The work will focus initially on the analysis of aerosol samples collected around New York State and will eventually be extended to include soil, water, sh, and tree samples. The samples will be analyzed using the IBA techniques of particle-induced X-ray emission, proton elastic scattering, parti...
A number of government programs, including USDA conservation programs, provide financial incentives to entice changes in behavior. An important question for these programs is whether temporary payments can lead to persistent behavioral changes. Over the past 20 years, the USDA Environmental Quality Incentives Program (EQIP) has provided more than $250 million to farmers adopting no-till crop pr...
anxiety is one common disorder during childhood. in curing anxiety disorders, there are different types of psychological remedies, pharmotherapy, family therapy, and music therapy that can improve the individual’s anxiety, but we need some other remedies to improve social and emotional relationship and interactions. considering the importance of curing the anxiety disorders, the effect of sand ...
In this paper, we identify a fragment of second-order logic with restricted quantification that is expressive enough to capture numerous static analysis problems (e.g. safety proving, bug finding, termination and non-termination proving, superoptimisation). We call this fragment the synthesis fragment. Satisfiability of a formula in the synthesis fragment is decidable over finite domains; speci...
A factorial experiment with two levels of Zn (0 and 1.5 mg Zn kg-1), five salinity levels of irrigation water (0, 60, 120 and 180 mM NaC1, and 120 mM NaNO3) in three replications was conducted. Wheat (Triticum aestivum cv. Roshan) was seeded in pots. After plant harvesting, zinc and cadmium concentrations were determined in the shoot. Activities of metal species in the soil solution were predic...

A FORTRAN computer program was developed to simulate nematode soil sampling strategies consisting of various numbers of samples per field, with each sample consisting of various numbers of soil cores. The program assumes that the nematode species involved fit a negative binomial distribution. Required input data are estimates of the mean and k values, the number of samples per field and cores p...
In the aftermath of the severe droughts and floods at the end of the 20th century, the Chinese government launched several ecological restoration projects, including the Natural Forest Protection Program in 1998 and the Grain-for-Green Program in 1999, to promote afforestation and reforestation to reduce surface runoff and consequent soil erosion nationwide. However, it is still unclear how veg...
Areca nut and sago are typical fruits of the Papuan Community which produce waste. Utilization waste for community itself has not been done optimally, especially in agriculture. One way to overcome problem soil fertility is by adding organic matter. shell stem alternative uses existing processing it into liquid fertilizer (POC) biochar. Adding matter can increase productivity affect biological ...
