Molds and mycotoxins in poultry feeds from farms of potential mycotoxicosis

Forty five finished poultry feed samples, collected from different broilers, broiler breeders and layers farms were divided into two parts, for mycological and mycotoxins examination. In counting of molds, dilute plate technique was used, whereas feed parts were used for mycotoxin estimation, they were subjected to four standard kits of Aflatoxin, Ochratoxin, T-2 toxin and Fumonisins. Mold counts were around 105 cfu.g-1 sample. Fourteen mold genera were recovered. From the systematic point of view, 2 genera belonged to Zygomycetes (i.e. Mucor, Rhizopus,), 1 genus belong to Ascomycetes (i.e. Eurotium); the majority, within so-called mitotic fungi (formerly Deuteromycetes), encompassed 11 genera (i.e. Acremonium, Alternaria, Aspergillus, Fusarium, Paecilomyces, Penicillium, Scopulariopsis,, Trichothecium, Ulocladium and Aerobasidium). The most frequent fungi were those from the genus Aspergillus. The concentrations of the four analyzed mycotoxins in the poultry finished feeds, and the percentages of the recovered mycotoxins, revealed that aflatoxins was recovered in 91.1% of the examined samples, with a mean value of 179.1µg/kg. The same percentage was found with Ochratoxins, but with lower mean concentration of 159.4µg/kg. In the third order were Fumonisins mycotoxins were in the third order, and they were recovered in 51.1% of the tested samples with a mean value of 127µg/kg. In the fourth order was T-2 toxin, with a percentage of 2.2% and a value of 50.0µg/kg

Mycofix ameliorative effect on Newcastle disease antibody production in broiler chickens during aflatoxicosis

Three experiments were conducted to elucidate the alleviation effects of Mycofix plus 3.0 on Newcastle antibody formation during aflatoxicosis in broiler chickens. Three levels of Mycofix (0.05%, 0.15%, and 0.25%) and aflatoxin (2.5ppm, 3.5ppm, and 5ppm) were used. Chickens were vaccinated at 8 and 18 days of age. Enzyme-linked immunosorbent assay and Haemagglutination inhibition tests were employed for determination Newcastle antibody titers at 28 days. The results showed that, Mycofix , and only at its high level of addition (0.25%) was effective in ameliorating the negative effect of aflatoxin at the rates 2.5ppm and 3.5 ppm levels of inclusion on antibody production but not at the high level of 5ppm on antibody production, comparing with titers in control groups

Detection of streptomycin residues in local meat of bovine and ovine

From meat retails in Mosul province, forty-five meat samples of local ovine and bovine (23 bovine samples and 22 ovine samples) were collected. The period of collection was during November 2010 to May 2011, by means of multistage random sampling for detection of streptomycin residues. Enzyme linked immunosorbent assay (ELISA) was used for detection of streptomycin residues. The results revealed that eleven ovine meat samples (50%) were positive to streptomycin residue, with a mean value 35.06 µg kg-1, while 14 bovine meat samples (60.86%) were positive to residual streptomycin with a mean value 59.56 µg kg-1. From the results, it is clear that all tested meat samples (ovine and bovine) were safe enough for human consumption

Potential contribution of low cost materials in clean technology

As the world's population approaches more than 9 billion, the strain on the planet's resources is steadily increasing. This demand can only be met by improving production methods to reduce the use of chemicals and the amount of chemical waste. Zeolites are among the least-known products for environmental pollution control, separation science and technology. This study investigates whether the use of geological sources as low-cost materials are suitable for zeolite synthesis and future applications. In this investigation natural montmorillonite clay, locally available in Erbil-Kurdistan, was used as raw material. The experiments were carried out in the presence of ultrasound 30KHz at 60°C and for different crystallization times (5, 10 &15 hours) and the results were compared with those obtained by performing conventional alkaline hydrothermal static syntheses under similar conditions and crystallization time of (90 hours). The raw material as well as the products was analyzed using; Fourier Transform Infra-Red (FT-IR), X-Ray Diffraction (XRD) and X-Ray Fluorescence (XRF) spectroscopy and scanning electron microscope (SEM). The experimental data were ascertained the formation of Zeolite successfully. Crystallization by ultrasound has been demonstrated to offer the possibilities of increasing the nucleation and crystallization rates of zeolites, improving the yield and directing the synthesis towards different crystal phases

Finite Element Analysis of Horizontal Axis Wind Turbine Blades Using NACA 4412 Series

Wind turbine technology is one of the rapid growth sectors of renewable energy all over the world. The ultimate objective of the project work is to increase the output power under specified atmospheric conditions. From the technical point of view, the output power depends on the shape of the blade. The blade plays a pivotal role, because it is the most important part of the energy absorption system. Finite element analysis was conducted by different materials used for blade fabrication namely glass fiber with epoxy resin, Aluminum and teak wood. The research work focuses on NACA4412. Also, the performance of a wind turbine blade is highly dependent on the structure Total deformation, Stress and Strain of the blade is critical to the wind turbine system service life. So, the wind turbine blades are analyzed taking these parameters into account

Fundamentals Knowledge of Investor and Its Influence on Investment in Capital Market- A Study from Dhaka Stock Exchange

A comprehensive investment literacy questionnaire surveyed to the participants in the Dhaka Stock Exchange (DSE) to measure the basic financial literacy and its effects to the stock market participants. It has been found that the majority of the respondents shows basic financial literacy, but they don’t believe that they have sufficient basic knowledge of investing in DSE. So the conflict between knowledge and their confidence leads them to wrong prediction of investment and the dependency on rumors on their investment decision. Inadequate knowledge about capital market not only sad loss, but also turns to an unattractive place of investment. Basic financial literacy not necessary prerequisite for a good investment decision in the capital market but help to make a preliminary decision of investment as well as to avoid a major loss.

Calculation of true coincidence summing correction factor for clover detector in add-back and direct mode

The true coincidence summing effect on the full-energy peak efficiency calibration of an unsuppressed clover HPGe detector has been studied. Standard multi-energetic and mono-energetic gamma-ray sources were used to determine the full-energy peak efficiency of the detector as a function of the gamma-ray energies at different source-to-detector distances. The true coincidence summing correction factors for the full-energy peak efficiency of the detector has been determined, in the add-back and direct modes of the detector, using both experimental and analytical methods. Geant4 simulations were performed to obtain the full-energy peak efficiency and total efficiency of the detector for different gamma-ray energies. The simulated efficiencies were used to calculate the correction factors using the analytical method. The correction factors obtained from both analytical and experimental methods were found to be in good agreement with each other. The clover detector in add-back mode exhibits larger summing corrections compared to the direct mode for the same source-to-detector distances. For the add-back mode, the coincidence summing effect is not significant for source-to-detector distances ~ 13 cm or above, whereas, for the direct mode, measurements can be performed for source-to-detector distances ~ 5 cm or above without considering the coincidence summing effect

The case for early use of rapid whole-genome sequencing in management of critically ill infants: late diagnosis of Coffin-Siris syndrome in an infant with left congenital diaphragmatic hernia, congenital heart disease, and recurrent infections.

Congenital diaphragmatic hernia (CDH) results from incomplete formation of the diaphragm leading to herniation of abdominal organs into the thoracic cavity. CDH is associated with pulmonary hypoplasia, congenital heart disease, and pulmonary hypertension. Genetically, it is associated with aneuploidies, chromosomal copy-number variants, and single gene mutations. CDH is the most expensive noncardiac congenital defect. Management frequently requires implementation of extracorporeal membrane oxygenation (ECMO), which increases management expenditures 2.4-3.5-fold. The cost of management of CDH has been estimated to exceed $250 million per year. Despite in-hospital survival of 80%-90%, current management is imperfect, as a great proportion of surviving children have long-term functional deficits. We report the case of a premature infant prenatally diagnosed with CDH and congenital heart disease, who had a protracted and complicated course in the intensive care unit with multiple surgical interventions, including postcardiac surgery ECMO, gastrostomy tube placement with Nissen fundoplication, tracheostomy for respiratory failure, recurrent infections, and developmental delay. Rapid whole-genome sequencing (rWGS) identified a de novo, likely pathogenic, c.3096_ 3100delCAAAG (p.Lys1033Argfs*32) variant in ARID1B, providing a diagnosis of Coffin-Siris syndrome. Her parents elected palliative care and she died later that day

Sustainability of Scientific Journals in the Developing World With Special Reference to Bangladesh

The study explores sustainability of scientific journal publication in Bangladesh. Forty-three journal editors were interviewed, and 66 current journals were physically examined for production quality, regularity of publication, and availability at concerned libraries. Findings revealed that 68% of the journals were published late, 30% had inconsistencies in typesetting, and 14% were indexed. Most journals were found either excellent or of good quality in terms of printing (85%), binding (77%), paper (92%), and graphic reproduction (76%). Most journals were not available in major libraries under study. Of the 43 editors, 28 (35%) reported a cost recovery of 1-45% from subscriptions, advertisements, and sales. About 74.4% of the editors did not consider their journals at risk. Although 86% of the editors were confident that their journals would be sustained in the long run, 37.3% could not give any convincing logic in support of their statement. Major problems include lack of skilled staff, finance, quality articles and institutional support, and lengthy peer review process. Only one journal editor was found to be a full-time editor having training in editing and publication. One-half (51%) of the editors reported have training in editing, while four had publication training. Most editors (79%) were interested in acquiring training in editing and publication. Institutional support and backup, enthusiasm and zeal of editors, unmet need for standard local journals, constant flow of funds and articles, and skilled manpower are instrumental for sustainability of science journals in Bangladesh
