Aflatoxins represent aggressive group of mycotoxins. They are really toxic, carcinogenic and dangerous for human health. There are mechanical, physical and chemical methods for their detoxification. Aflatoxins could be also neutralized by means of various adsorbents as well. We do some research work in the direction of aflatoxin adsorption by presence of lignin, which is quite affordable and gives an effective result.

Aim/Objective: The author writes the manuscript by reviewing the literatures related to the biomedical application of metallic nanoparticles. The term metal nanoparticles are used to describe the nanosized metals with the dimension within the size range of 1-100 nm. Methods: The preparation of metallic nanoparticles and their application is an influential area for research. Among various physical and chemical methods (viz. chemical reduction, thermal decomposition, etc.) for synthesizing silver nanoparticles, biological methods have been suggested as possible eco-friendly alternatives. The synthesis of metallic nanoparticles is having many problems inclusive of solvent toxicity, the formation of hazardous byproducts and consumption of energy. So it is important to design eco-friendly benign procedures for the synthesis of metallic nanoparticles. Results: From the literature survey, we concluded that metallic nanoparticles have applications in the treatment of different diseases. Metallic nanoparticles are having a great advantage in the detection of cancer, diagnosis, and therapy. And it can also have properties such as antifungal, antibacterial, anti-inflammatory, antiviral and anti-angiogenic. Conclusion: In this review, recent upcoming advancement of biomedical application of nanotechnology and their future challenges has been discussed.

An experiment was conducted to compare various physical and chemical methods of castration of lambs at 15 and 60 days of age. Their effects on body growth, feed efficiency, dressing percentage and profitability were studied. At birth 100 lambs were divided among the 16 different treatments according to sex and the following breeding groups: Suffolk, North Country Cheviot, two-breed cross and three-breed cross. The different methods of castration were: complete removal of the testicles, Burdizzo, elastrator and partial castration. The sterilization methods consisted of intramuscular, intratesticular and intraveinous injection of cadmium chloride. All lambs were weaned at 30 days of age and placed in individual pens. They were subjected to similar environmental conditions and shipped to slaughter at approximately 45 kg body weight. Significant differences were observed among breeds, sexes and the various castration methods for daily gain, feed efficiency, days required to reach market and profitability. Age at castration did not have any important effect ort the variables measured. Superior gains, feed efficiency and profitability were observed for the partially castrated group, for the lambs that received an intramuscular injection of cadmium chloride and for the non-castrated males. All treatment groups involving males were superior to the females for the characters studied except for dressing percentage.

One effective method to minimize the increasing cost in the construction industry is by using coal bottom ash waste as a substitute material. The high volume of coal bottom ash waste generated each year and the improper disposal methods have raised a grave pollution concern because of the harmful impact of the waste on the environment and human health. Recycling coal bottom ash is an effective way to reduce the problems associated with its disposal. This paper reviews the current physical and chemical and utilization of coal bottom ash as a substitute material in the construction industry. The main objective of this review is to highlight the potential of recycling bottom ash in the field of civil construction. This review encourages and promotes effective recycling of coal bottom ash and identifies the vast range of coal bottom ash applications in the construction industry.

Health informatics is one of the main branch of engineering which provides a solution to a variety of problems like delayed, missed or incorrect diagnoses with the help of computational techniques. With the help of technologies such as bio-computing, health informatics, the disaster impacts on both human health and biological factors can be reduced to a large extend. Using these computational technologies, the country’s economy can also get boosted up and due to increased disease-causing pathogens, which directly impact the human health system. In this research work, a different type of sugarcane disease is detected and classified because manual identification is difficult and time-consuming. So, the farmers couldn’t find a better solution, than on the whole, they go for stubble burning, which is an alarming issue both on human and environmental wellness. The burning of bagasse causes bagassois, an interstitial lung disease that affects the tissues present in the lung through the air sacs. So, this sugarcane disease detection needs to be done early to avoid various health and environmental issues. The proposed work consists of the detection of four types of sugarcane leaf disease directly from the field. The sequence of methods is capturing images with WSN nodes, pre-processing with image enhancement and noise removal (IENR), segmentation with Fuzzy membership function and clustering (FMFC), feature extraction using Gray Level Co-occurrence Matrix Vector (GLCMV) and classification using Support Vector Machine (SVM). With the help of the effective proposed method, the highest parameters like precision, accuracy, sensitivity, and specificity for sugarcane leaf disease have been obtained. Based on the successful implementation process, the accuracy stated for the four sugarcane diseases along with the execution time is given below as Smut disease (87.12, 1.01 sec), Rust disease (90.23, 1.02 sec), Grassy Shoot disease (95.34, 1.047 sec), Red Rot disease (95.51, 1.04 sec).

Разработана технологическая схема получения жидкого сахара из полупродуктов свеклосахарного производства, которая предусматривает получение исходного (концентрированного) сахарного раствора из сиропа после выпарки, некондиционного сахара и желтого сахара последнего продукта с содержанием сухих веществ (СВ) от 68 до 72. Изучено изменение количества микроорганизмов в жидком сахаре в течение 30 сут хранения в закрытых сосудах при температуре окружающей среды без предварительной обработки физическим и химическим способами с целью использования сиропа при производстве пищевых продуктов. Установлено, что в растворе с содержанием СВ 68 72 количество микроорганизмов увеличилось: бактерий с 15 до 60 КОЕ/г, дрожжей и плесневых грибов с 10 до 34 КОЕ/г, что не превышает допустимых уровней СанПиН 2.3.2.1078 01 и ГОСТ Р 53035 2008. Определена длительность хранения жидкого сахара для использования в пищевых производствах не более 15 сут. The technological scheme of obtaining liquid sugar from semiproducts of sugar beet production, which provides for obtaining the initial (concentrated) sugar solution from the syrup after evaporation, substandard sugar and yellow sugar of the last product with a content of dry matters from 68 to 72, has been developed. The change in the number of microorganisms in liquid sugar was studied during 30 days of storage in closed vessels at ambient temperature without preliminary treatment by physical and chemical methods with the aim of using syrup in food production. It was found that in the solution with the content of dry matters 68 72 the number of microorganisms increased: bacteria from 15 to 60 CFU/g, yeast and fungi from 10 to 34 CFU/g, which does not exceed the permissible levels of SanPiN 2.3.2.1078 01 and GOST R 53035 2008. The storage duration of liquid sugar for use in food production was determined no more than 15 days.
