This study aimed to assess the acceptability of the Coconut Meat Sisig Recipe among Senior High School teachers. We employed a descriptive research design and utilized a survey technique for data collection. The data were collected through an adapted and modified questionnaire. We used Frequency Count and Percentage Distribution, Mean and Standard Deviation, and Analysis of Variance (ANOVA) as statistical tools. The results indicated that the Coconut Meat Sisig recipe is highly acceptable in appearance, color, aroma, taste, and texture. The innovative incorporation of coconut meat as the primary ingredient received a positive reception, demonstrating the dish's potential for favorable adoption in the culinary preferences of this target group. Furthermore, the Coconut Meat Sisig recipe enjoyed universal acclaim, with slight variations in perception related to educational backgrounds concerning texture. Given its broad acceptance among Senior High School teachers, it is recommended to promote the Coconut Meat Sisig recipe as an innovative and attractive option for school canteens.

Briquetting is a mechanical compaction process for increasing the density of bulky materials. Briquette is an example of biomass which is a renewable source of energy. As the world turn to renewable energy due to global warming, depletion of fossil fuel reserves and deforestation. The demand for briquetting machines is on the increase. This high demand and large market for briquetting machines has result in the need for briquetting machines with extended capabilities and design customization. This calls for an elaborate conceptual design phase. This research adopts a fuzzified Multi Criteria Decision Making (MCDM) model, (COPRAS) to identify the optimal conceptual design from four conceptual designs of briquette making machine, operating based on different principles. This was achieved by considering eight (8) design features and their sub features as the criterion to analyze, evaluate and measure the four conceptual designs. The result shows that in applying the COPRAS-F model, several decision makers choice can be factored into the process of choosing an optimal design, from a group of designs and still generate a valid result.

A method for predicting surface thermal failure of gears made of plastic materials and their natural fiber composites is developed with the “Verein Deutscher Ingenieure (VDI)” “Association of German Engineers” method, and a simulation is made for these gears. The simulation is carried out for Duracon acetal gears and composite material of high density polyethylene (HDPE) with 40% birch wood fiber (HDPE40B) gears. The simulation is carried out with the same meshing characteristics that were used to carry out the tests on the gear test bench in real simulated operation to study the thermo-tribo-mechanical behavior of HDPE40B gears. From the predefined operating temperature, the torque-speed (C-ω) limiting curve is established using the computer program for predicting operating temperatures. Then the heat map is established using the same temperature calculation program by determining the equilibrium temperatures in the tooth and instantaneous temperatures on the profile according to the normalized positions S/pn. The induced surface contact stresses are then determined according to the normalized positions S/pn with the VDI method and are compared with the limit allowable stress. The results show that more severe operating conditions give comparatively lower induced stresses, but they are nevertheless the ones that will fail first at surface thermal failure compared to less severe operating conditions. In other words, the results show that the more severe the operating conditions, the shorter the operating cycles become before surface thermal failure occurs. The results also show that the surface thermal failure behaviors for plastics and composites gears are similar and the higher the melting temperature of the material, the butter it can stand surface thermal failure in more severe working conditions.

Speed breeding is a cutting-edge breeding method with the potential to revolutionize the agricultural industry. Speed breeding significantly reduces the time it takes for crops to mature, enabling the production of several generations each year. This is accomplished by adjusting environmental conditions like temperature, light quality, and photoperiod duration. Researchers and breeders can create new crop varieties with desired features more quickly thanks to this faster breeding procedure. Compared to conventional breeding techniques, speed breeding has a number of benefits. It makes it simpler to generate improved cultivars with higher yield, disease resistance, and other desirable qualities since it enables the swift evaluation and selection of plant attributes. Speed breeding speeds up the breeding process, allowing scientists to adapt to shifting environmental factors and developing agricultural problems more quickly. While speed breeding offers tremendous potential, there are also limitations and challenges associated with its implementation. Factors such as plant species, specific traits, and optimal growth conditions need to be carefully considered. This system involves manipulation of growing conditions by different ways, here three of the methods are described. As the population of world is increasing day by day so to overcome the risk of global food security and to cope with such future problems, such rapid crop improvement approaches need to be implemented. Speed breeding approach is an old concept but its implementation in the field of breeding has not been exploited to a greater extent. However, ongoing advancements in technology and further research is likely to overcome these challenges, making speed breeding an increasingly valuable tool for crop improvement in the future.

This study aimed to create an iron-rich dietary supplement utilizing spirulina and other nutritionally dense ingredients—quinoa, soybean, and amaranth—in the form of a pancake premix. The pancake premix was formulated, prepared, and analysed for its nutritional composition. The premix was meticulously developed by combining ingredients from various food groups, incorporating vanilla powder for flavour. The preparation involved simple steps to produce the final pancake product. Following the preparation, a thorough nutritional analysis was performed, covering moisture, ash, fat, protein, iron, crude fibre, and total carbohydrate content, adhering to established protocols such as AOAC methods. The results revealed that the spirulina pancake premix contained 4.5% moisture, 12% ash, 4.6% fat, 11.7% protein, 67.8% carbohydrates, 5.7% iron, and 0.83% crude fibre. Furthermore, based on the Food Composition Table, the premix provided 460 kcal of energy, 16g of protein, 87g of carbohydrates, 3g of fat, and 8.5g of iron per serving, meeting substantial nutritional requirements. Microbial analysis indicated limited microbial growth, attributed to the airtight sealing of the premix in silver plastic bags, which effectively prevented contamination and extended the product's shelf life. The pancake premix demonstrated promising nutritional content and microbial control, suggesting its potential as an iron-rich dietary supplement for addressing nutritional deficiencies, particularly among anemic adolescent girls.

Renewable energy is the most promising energy-saving and environmentally friendly option. The concentrating type solar collector like parabolic trough collectors can be utilized for solar thermal energy collection due to low cost and high-temperature output. The paper is an experimental study of a solar parabolic trough collector with manual sun tracking. A parabolic trough with an area of 2.5´1.75 m² was constructed for the present study. A highly polished aluminum sheet for concentrating the reflecting sunlight to the focal line contains the receiver tube. The parabolic trough was tracked at regular interval of one hour concerning the sun position and focused the sunlight into the receiver tube to ensure sound performance. Water is used as a working fluid inside the receiver tube, and experiments were done with three different mass flow rates of 0.0072,0.0112 and 0.0158 kg/s. Two heat-collecting elements, such as a stainless-steel receiver tube and a glass-coated copper receiver tube, were tested with a parabolic trough. The performance was analyzed based on the difference in the inlet and outlet temperature of the working fluid at the ends of the receiver tubes of the parabolic trough. The instantaneous efficiency of the parabolic trough with two different materials of receiver tube at three different flow rates were evaluated. The results showed that the glass coated copper tube surpassed in performance compared with stainless steel receiver tubes. The instantaneous efficiency of the glass coated copper tube is found to be 71.17% at a flow rate of 0.0158 kg/s which was significantly high when compared with that of the stainless-steel receiver tube. The glass coated copper tube prevents the convective heat transfer loss and thereby increases the efficiency. The experiment shows that the performance of the parabolic trough solar collector strongly depends upon solar light tracking and the focal line containing the receiver tube.

The experiment shows that the performance of the parabolic trough solar collector strongly depends upon solar light tracking and the focal line containing the receiver tube.","PeriodicalId":10730,"journal":{"name":"Current Journal of Applied Science and Technology","volume":"375 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139160670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Nolia Nuagaon (Bada Noliya and Sana Noliya Nuagaon), fisher communities rehabilitated between the newly revived Tampara Lake, Bay of Bengal, and Rushikulya Estuary. The coastal ecosystem and habitation within this sandy beach vegetation in the past are regularly affected by storm surges, coastal erosion, and floods. The fisher group relies on the sea and the estuary for their livelihood. They are politically, and socio-economically deprived. The present study envisages the societal and economic changes due to the altered ecosystem due to climate changes, Regional Sea Level Rise (RSLR), and human interventions. The basic tools involved are Hazard Vulnerability and Capacity Assessment (HVCA), and Ecosystem Services Shared Value Assessment (ESSVA) using the policies piloted by the International Lake Environment Committee (ILEC) for Eco-DRR, Partners for Resilience (PfR). The Nolia Nuasahi (Bada and Sana) villages were under threat on the coastal front. The search helped to train the community to understand the pioneer issues and coercions that are surging up with time and the fishing profession, which is now replaced by migration and marginalization adding to their age-old lifestyle. The growth of tourism activities in the nearby Tampara Lake shall bring challenges to the landscape, supporting Ecosystem services and the fishing community’s regime. A joint Action Plan between the Lake and coastal ecosystem is warranted to be developed to maintain a better livelihood for the villagers after acceptance from the Gram Sabha and then included in the Gram Panchayat development plan (GPDP) to boost SDG-14.

Poultry farming plays an important role in the livelihood for the farmers of hilly areas of Jammu & Kashmir. The hilly area farmers face a lot of constraints in poultry farming which affect their poultry birds productivity. Poultry farming is an important occupation in Reasi district of J&K. To identify the constraints involved in poultry farming by the farmers residing in hilly areas, the present study was conducted in the hilly district Reasi of Jammu and Kashmir which was selected purposively. A sample of 120 poultry farmers was selected from the selected villages. The major constraints identified were lack of lack of poultry feed in some months of the year, high disease incidence and a lack of improved strains of poultry. The majority of poultry farmers opined that there is a need to encourage the farmers to grow Azolla specially in off-season, a need of subsidy of poultry feed, awareness-cum training on poultry farming and market channel for the sale of products(eggs and meat) for better remunerative prices for the meat and eggs.
