Failure analysis of an economizer tube sheet & its cover due to corrosionand imperfection

The boiler's economizer was found to be inefficient. Corrosion is suspected to be the source of the economizer's pressure reduction. The examinations included visual inspection, stereomicroscope, metallography, elemental microanalysis by EDS, and chemical composition analysis. The economizer failed due to a weld crater caused by improper welding, which induced residual welding stress. The slight sulfur content of the condensed or flue gas that causes rusting on the economizer's outer cover is not considered a severe failure issue. Material SUS304 stainless steel is the right selection for economizer materials.

Enhancement of Orientation of Corn Shelling Machine

Shelling is one of the most responsible and post-harvest operations of the plant. Production of various types of grain, peeled from the bark and traditionally. It is a traditional show of corn and the most time-consuming activities included hard work, grain loss and felling, chipping through a bite, using sticks, and using animals to step on multiple locations. Modern corn huskers tend to be large and heavy, high energy, which require high scaling capabilities. Additional expenses, the purchase of huskers, this is a high level of agriculture, small farmers-owners. Therefore, the aim of this study is to design, construct, and evaluate the performance of a small corn husker engine management system. It was built with both local, affordable materials and its cost is very low and affordable. The main components of the machine are: hood, scale block (musician, drum and concave), outer cover, shaft, frame and exhaust port. The location of these elements in relation to the belt and pulley. Engine capacity of 2 HP. provides drive through pipeline connections with the drive pulley show in between. Existing methods in the case of maize, de-zoom, the agro-industrial complex consists of crushing grain manually or using machines to the proper extent, and not one of them is effective, so as not to invest money in the development of the economy, public relations. Therefore, there is a need for an innovative idea for a product that is feasible, safe, cost-effective and efficient for the Indian farmer.

MICROMORPHOLOGY OF TEGUMENT OF EURYTREMA PANCREATICUM BEFORE AND AFTER ANTHELMINTICS

The article describes micromorphological features of the tegument of the trematode of the species Eurytrema pancreaticum (Janson, 1899), Loos, 1907, family Dicrocoelliidae Odhner, 1911. The parasites were collected by dissection of spontaneously infected animals (cattle) with Eurytrema and with formed chronic eurythrematosis. Some of the trematodes were collected from the control group of animals, and some after deworming with anthelmintics. Using histological methods in a comparative aspect with the control, changes in the morphological features of the tegument of Eurytrema after effect of hexachloroparaxylol and oxinid were shown. It has been established that the toxic effect of anthelmintics causes destruction of the tegument. This increases the permeability of the drug and its metabolites through the outer cover of the trematodes into their body. There is a complete atrophy of the outer part of the tegument, and in the inner part of the tegument there is a decrease in the number of degenerative cells with hexachloroparaxylol and their increase with oxinid. The comparative effect by two anthelmintics of the old generation on the tegument is described to emphasize the effectiveness of their use in trematodiases, on the one hand, and to show the quality of histological methods in the expert assessment of drugs, on the other.

Gol Gumbad, Bijapur

This report on the Gol Gumbad provides a detailed explanation for this decay, as also an excellent summary of the repairs carried out since the early part of the twentieth century, even the views of various engineers and archaeologists who had examined it. The deterioration of the inner dome, it seems, was a consequence of rainwater annually finding its way into the masonry core, which was partially addressed by the guniting of the outer cover.

The technologies that were used in the development of the rotary module are metal machining and plastic printing by additive technology. It also deals with materials that were used in the production of the first generation of the functional prototype and in the development and testing in the pre-production phase.

The pH of soaps, skin care products and cosmetics used in the period of COVID-19 pandemic

Introduction. Human skin is the outer cover of the body. It performs important functions for the entire organism, such as protection of internal organs. The skin also protects the body against the effects of the external environment, ensures the balance between the environment and the inside of organism. Due to the pandemic, all members of the public are encouraged to frequently wash or disinfect hands, which may lead to skin irritation. Aim. The aim of the study was to check the pH of soaps, skin care products and selected cosmetics used in the period of COVID-19 pandemic. Materials and methods. For pH determination the CP-105 pH meter manufactured by ELMETRON® (Poland) was used. A total of 111 products available on the Polish market were collected for testing. The results were compared with the pH of tap water samples. Results. The soaps had mean pH of 5.04±1.04, shampoos 6.04±1.57, creams 6.87±0.1, products for depilation 9.8±3.06. All the values were within legal ranges. Conclusion. The majority of skin and hair cosmetics have pH close to the pH of tap water. Chemical hair removal products have the most alkaline pH and therefore, require extreme caution as they can cause irritation.

Pesticide knowledge and safety practices in farm workers from Tubah Sub-Division, North West Region, Cameroon

This study aimed to evaluate the safety measures practiced by farmers with use of pesticides in Tubah Sub-Division. The data gathered would be useful for drafting policies related to use of pesticides to reduce its effects on human health and the environment. This survey was carried out in November 2016 in Tubah Sub-Division, Mezam Division of the North West region of Cameroon. A structured questionnaire was administered to 120 homesteads of the study area. The results revealed that 94.2% of the farmers were untrained in pesticide safety measures, 30.8% did not observe any safety interval before consuming freshly treated crops and 25.8% did not read instructions on pesticide labels before handling. Fifty five percent of the farmers did not use any protective equipment, 79.2% practiced careless pesticide disposal, 13.3% stored pesticides in stores and 7.5% stored pesticides inside their houses. Eighty percent of the families stored their crops via hanging in the house and smoking the crops, while 10.8% stored their crops in sealed bins. Water washing followed by removing the outer cover was applied as a crop cleaning procedure prior to cooking or consumption. Major symptoms such as headache, wheezing, dizziness and skin problems were observed in the homesteads. Some environmental changes observed after application of pesticides were damage of non-target plants and disappearance of insects. It could be concluded that in Bambili, farmers lacked proper knowledge regarding safe handling and use of pesticides and the adverse effects of improper pesticide use to human health and the environment.
