Optical Parameters of Varies Thickness of Bismuth (Iii) Iodide Thin Films for Photovoltaic and Nonlinear Applications

We report in varies thickness of BiI3 thin films by thermal evaporation techniques onto glass substrate. The films were strongly oriented along the (113) plane. The structural parameters of these films (crystallite size and lattice strain) were determined using (XRD) pattern. The thicknesses and refractive indices of the films were considered using Swanepoels method. The band gap was determined in terms of T and R spectrum in the UV-region of the absorption. The possible optical transitions of all films are found to be allowed direct transition with energy gap fluctuate bout 1.96 ± 2% eV. Dielectric constant, volume-energy-loss function (VELF) and surface-energy-loss function (SELF) for as deposited films were discussed in terms of film thickness rising. The change in optical parameters have been interpreted in terms of the change in microstructure parameters. BiI3 is recommended for photovoltaics and nonlinear optics because of its higher absorption coefficient, dielectric constant, and fair band gap

Whither the species? Phytophthora taxa, MOTUs and barcodes in the world of metagenomics

The study of ecosystem diversity is being transformed by high throughput sequencing technology that allows an unparalleled depth of sampling of DNA barcode sequences. The opportunities are great at this fascinating interface of pathology, ecology, taxonomy and molecular biology but there are pitfalls. It is important to consider the potential for bias at all steps in the process from sampling through to data analysis. Increasingly Phytophthora diversity is being examined by metabarcoding of the PCR amplified rDNA ITS regions from soil, water or plant sample DNA. We have applied baiting and isolation, cloning and Sanger sequencing and Illumina MiSeq analysis to a time-series of filtered water samples from several Scottish streams within a UK-wide sampling network. These data, the literature and other presentations in this session will be explored in a critical analysis of the field. A specific focus will be placed on exploring the range of species and their boundaries, the potential for species quantification and possible benefits of the technology for plant health legislation

Therapeutic Management, Clinicopathological, Molecular and Cost Studies on Sarcoptes scabiei Infestation in Rabbit

Sarcoptic Mange is a highly contagious parasitic disease that can cause huge economic losses to rabbit producers and has the potential to infect humans. This study aimed to perform molecular characterization and phylogenetic analysis of Sarcoptes scabiei, assess redox and inflammatory state, evaluate the cost and efficacy of a single dose of a commercially available ivermectin with a topical application of sulfur ointment for control of this issue. Skin scraping was collected from infested rabbits in Ismailia governorate, Egypt, and submitted for parasitological examination. The mite specimens were identified based on ITS2 PCR gene. Forty-four adult rabbits naturally infected with mange and 5 free animals were divided into three groups, group 1, 1% ivermectin was injected subcutaneously once, the affected area was soaked with 1% deltamethrin, and sulfur ointment 10% was applied every 2 days. Group 2 received two injections of ivermectin with an interval of 2 weeks while group 3 was non-infested rabbits. Skin scraping and serum samples were taken for parasitological and clinicopathological examination and the cost of each treatment was calculated. A high degree of sequence variation was observed between our sequence sample and some other Sarcoptes scabiei sequences from Egypt and different geographic areas. MDA and IL-6 levels were significantly increased, and TAC was significantly decreased in the infected groups compared with the uninfected group. On the 28th day of treatment, hair growth and complete skin recovery were observed in both treated groups. A single dose of 1% ivermectin with topical treatment is sufficient to eliminate Sarcoptes scabiei but is costly.
