In this paper we propose a novel method for measuring re-flectance of isotropic materials efficiently by carefully choosing a set of sampling directions which yields less modeling error. The analysis is based on the empirical observation that most isotropic BRDFs can be approximated using 2D bivariate representation. Further a compact representation in the(More)
Phosphorus (P) is essential for plant growth and productivity. It is one of the most limiting macronutrients in soil because it is mainly present as unavailable, bound P whereas plants can only use unbound, inorganic phosphate (Pi), which is found in very low concentrations in soil solution. Some ectomycorrhizal fungi are able to release organic compounds(More)
Since the first report of infectious bursal disease in Pakistan in 1987, outbreaks have been common even in vaccinated flocks. Despite appropriate administration of vaccines, concerns arise if the circulating strains are different from the ones used in the vaccine. Here, we sequenced the hypervariable region (HVR) of the VP2 gene of circulating strains of(More)
A multidisciplinary, collaborative project was conducted to determine the prevalence and distribution of soil-borne zoonotic pathogens in Lahore district of Pakistan and ascertain its Public Health Significance. Using a grid-based sampling strategy, soil samples (n = 145) were collected from villages (n = 29, 5 samples/village) and examined for Bacillus(More)
The development of resistance in bacteria against commonly used antibiotics/drugs is of considerable medical significance. Aim of this study was to determine the microbial load of un-pasteurized packed fruit juices sold in Lahore city and to determine antibacterial activity of five different honey samples against isolated bacteria. Unpasteurized fruit juice(More)
