Production of Vinegar from Pear Juice and Comparative Analysis of its Quality with Apple Juice Vinegar
No full textVinegars are the product of scalar fermentations carried out by several groups of microorganisms acting at different moments in time. Apple vinegar is made with apple juice or concentrated Apple juice (CAJ) through a double fermentation: alcoholic and acetic. Vinegar was successfully produced from the juice extracted from pear using yeast and acetic acid bacteria. This study presents a summary of research concerning the quality of vinegar made from pear and apples by using double distillation method. Juice is extracted from both the apple and pear and was analysed for several parameters like pH, brix, specific gravity, Total Reducing Sugars (TRS), Reducing Sugars (RS), titratable acidity, alcohol percentage and Total Dissolved Solids (TDS). pH of pear and apple juice was found to be 4.82 and 4.35 respectively. pear and apple juice had the Brix of 8.5° and 12° respectively. The TRS of pear and apple juice was found to be 10.2%and 11.87 % respectively. Quality characteristics between pear vinegar and apple vinegar were investigated which includes pH, titratable acidity and alcohol percentage. The alcohol percentage of pear vinegar is slightly less than apple vinegar but the titratable acidity of pear vinegar was slightly more as compared to apple vinegar. Also pH of pear vinegar and apple vinegar are found to be 3.60 was 3.58 respectively. Acetic acid bacteria were isolated from Pear and apple vinegar prepared, using Frateur medium and Glucose Yeast Peptone (GYP) agar medium. Aceto Acetic Bacteria (AAB) isolated was confirmed to be Gram negative rods through Grams staining. The study reveals that pears being a seasonal fruit and cheaper compared to apples can be used to prepare healthy vinegar of best quality by a simple double fermentation method
Automated Fish Feeder Using Scheduler Mobile Application
No full textToday\u27s fish feeder technology is a device dedicated to reducing labor costs and creating a better feed dispensing system in local fish farming productions. In this study, a newly developed automated fish feeder using a mobile scheduler application is designed and implemented specifically for Milkfish (Chanos Chanos) production. The development consists of four phases; online research, system design, purchase of materials, and construction. Two types of testing were conducted to evaluate this technology, including a functionality test and a technology acceptance test. The functionality test of the technology was tested using experimental analysis, which uses simulation to test the functionality of the developed system. Seven (7) trials tested the automated fish feeder using the mobile scheduler application for seven days. The study shows that this device was consistent in dispensing 0.43 Kilograms of feeds for one feeding schedule and 0.86 Kg for two feeding schedules, based on the total kilograms put in the system. There were ten respondents that participated in the technology acceptance test. From this test, the mean score values for all items such as availability, aesthetics, and performance were found to be more than 3.7 (using a 5-point Likert scale), which means that the automated fish feeder using the mobile scheduler application is very acceptable according to the technology acceptance test. The developed automated fish feeder using the mobile scheduler application will help the farmers remotely feed fish without hassle and optimize the quantity of feeds for the milkfish
Impact of Urbanisation on Land Use Pattern in Tamil Nadu: An Economic Analysis
No full textChanges in land use that eventually resulted in less land being used for agriculture and more space being used for housing in most metropolitan populations. Land use changes have a variety of ecological effects on both urban and rural locations. One of the most notable land use dynamics is the conversion of land that occurs around the periphery of large cities due to a variety of economic and demographic causes. The specific objectives set forth for the study are, to analyse the temporal changes in the land use pattern of the study area and also to estimate the dynamic changes of land use categories and the loss of agricultural land in the study area. The changes in the land use pattern were estimated for the period from 2000-01 to 2019-2020 and further discussed as two decadal periods. The results revealed that there had been a significant decline in the net area sown, while the area under land put to non-agricultural uses and fallow lands, had a sharp increase. This shift in the land use categories might be due to the increasing demand for urbanization and infrastructure development, as a result of population pressure
Exploring Risk Factors of Suicidal Behaviour among Medical Professionals in the UK: A Retrospective Analysis of Online News Portals
No full textSuicide is a significant global health burden. The demanding nature of the healthcare profession, combined with unique stressors and challengses, puts medical professionals at risk of mental health difficulties, including suicidal ideation and attempts. This study aims to investigate suicidal behaviour among medical professionals in the United Kingdom by reviewing online news portals and focusing on the risk factors associated with suicide. Seven online news portals from the UK were purposefully selected for the study, focusing on news reports of suicides among medical professionals. Only English online news portals were chosen, as English is the standard language in the country. Out of the 61 reports, 37.7% of the reported suicides were among males, and 62.3% were among females. The age distribution of the suicide reports revealed that the majority of the cases are within the 20-30 age range (42.6%). Mental health issues and fear of losing their job were also prominent reasons (24.6%). Suicide among healthcare professionals in the United Kingdom has drawn little attention. Suicide is more prevalent in early adulthood and among female professionals. Nurses, doctors, and junior doctors are more likely to commit suicide
Influence of Crack Inclination Angle and Thickness on Mode-Mixity Using FEM
No full textMode mixity is common in fatigue growth problems to assess the integrity of components by obtaining the fracture parameters as stress intensity factor, T-stress, J-integrals etc. Present study aims to investigate the effects of fracture parameters in a modified Compact Tension (CT) specimen using finite element methods (FEM) with ANSYS 2022 software. Crack orientation angle (α) and thickness (t) have their effects on crack growth which affect the life of a mechanical component. With increasing the crack inclination angle (0°, 15°, 30°, 45° and 60°), an increase in mode III stress intensity factor is noticed while mode I showed a significant decrement. Pure mode I is notice at 0°. With further increase in the angle mode-mixity (mode I and mode III) is obtained. Also, with an increase in the thickness (8mm, 10mm and 12mm) of component there is a noticeable decrease in all modes of stress intensity factor. This mode-mixity play a crucial role in the cracked model of the specimen
Study of the Potential Toxicity and Side Effects Associated with the Long-term Consumption of Walnuts (Cola verticillata: Sterculiaceae): Anti-Meiosis in the Insect Assay
No full textCola verticillata (Sterculiaceae) is a plant that produces nuts renowned for their ceremonial, cultural, medicinal and above all economic value in Africa. The study consisted in evaluating the cytotoxic and genotoxic effects of the aqueous extract of the plant\u27s nuts on the Zonocerus variegatus model. Male and adult locusts were treated with increasing concentrations of 5, 10, 20, 30 and 40 µg/ml. The 0.01 ml/mg extract was administered intraperitoneal and 96 h post-treatment the grasshoppers were killed, dissected and the testicular follicles removed for smear preparation. Chromosomal examinations revealed that the aqueous extract of C. verticillata induced a significant regression of the meiotic index, followed by a significant increase in the chiasmatic frequency in a concentration-dependent manner and in comparison with the control group. In addition to chromosome bridges, chromosome breaks, sticky chromosomes and leak chromosomes were observed mainly at 40 µg/ml. These results show that Cola extract is cytotoxic and genotoxic because it slowed down meiosis while also inducing multiple chromosomal abnormalities with clastogenic effects in the male Z. variegatus breeder. The results of this study call for populations to consume kola nuts (Cola verticillata) intermittently if the cytotoxic and genotoxic effects are not reversed

Fungicides and Bioagents Are Used to Manage Downy Mildew on Pearl Millet
No full textPennisetum glaucum (L.), pearl millet Known by most as bajra, it is a significant warm-season grain that is mostly farmed in India under rainfed circumstances. In India, downy mildew caused by Sclerospora graminicola (Sacc.) Schroet is the most common and deadly disease affecting pearl millet. Two weeks after seeding, the illness was visible as chlorotic stripes on the leaf surface advanced from the base to the top. Most infected plants were unable to develop typical, healthy earheads. The bioagents that were examined as seed dressers were Trichoderma harzianum (6 g/kg seed), Pseudomonas fluorescens (8 g/kg seed), Trichoderma viride (6 g/kg seed), and neem oil and water. The downy mildew disease incidence was significantly reduced (2.83%) by the fungicides Mancozeb at 0.2%, Neem oil, Metalaxyl at 0.25%, and Carbendazim at 0.25%, as compared to the control, which had a documented disease incidence of 40.33%. Neem oil considerably outperformed all evaluated bioagent seed dressings for downy mildew prevention, including the seed dressing containing Pseudomonas fluorescens seed treatment at 8 g/kg seed was statistically comparable to Trichoderma harzianum seed treatment at 6 g/kg seed and Metalaxyl application at 0.25%. The downy mildew was also greatly reduced by foliar application of Mancozeb at 0.2 % and seed treatment with Metalaxyl (6 g/kg seed) + spray of Propiconazole at 25% EC at 0.25%; these two methods outperformed the seed dressing with all evaluated bioagents. The positive outcome of using neem oil topically suggests that, when it comes to managing downy mildew in pearl millet in an environmentally benign manner, it might replace fungicides
