Fruits on processing yield about 15 to 30 per cent of by-products which are under-utilized. Pomace is theresidue or by-product that is obtained during processing of fruits and vegetables. Amla-pomace for its nutritionaland functional properties can be exploited by food processing sectors for development of varieties of processedfoods. Present Study aims on development of value added products using Amla-pomace. Value added products suchas noodles, pasta, waffles, chocolate waffles and cookies were developed by incorporation of amla pomace. Alsonutritional properties and sensory qualities were analysed for the products developed. Four variations weredeveloped with 5, 10, 15 and 20 per cent incorporation of amla pomace. The results showed that products developedwith amla-pomace are acceptable for its organo-leptic quality and nutrient composition. Amla-pomace can beutilized for product development.

A transmission tower is a tall structure, usually a steel lattice tower used to support an overheadpower line. They are used in high voltage AC and DC systems. Steel tower structure resting on footings arecurrently becoming popular in any geographical location for electrical transmission, microwave transmissionetc. It is necessary to have an understudy of the behavior of such structures and provide an economical design.To understand the performance of such high rise structures, it is necessary to know their behavior consideringthe soil structure interaction. Modeling of Transmission tower for the validation purpose is done. The basicsoil properties of laterite were also found accordingly. Here the entire transmission tower with the isolatedfooting is modeled and analyzed in STAAD Pro V8i and STAAD Foundation software. The total loadtransmitted to each tower leg is found using STAAAD Pro and the size of isolated footing under each tower legis determined using the STAAD Foundation software respectively. If required the soil structure interactioneffects (SSI) can also be found easily

Now a days the news of coronavirus is on all news paper’s headline. Coronavirus is spreading fromanimal market of Wuhan in central China. There are several types of coronavirus but all are not dangerous but thisnew coronavirus is very dangerous. It is a group of RNA viruses that cause a variety of disease in animal andanimal to human. The efficiency of this new coronavirus found in the live animal market of Wuhan in central China,circulate in a range of animals and spread from animal to animal and animal to human also which is calledSpillover. Mild symptoms of coronavirus are cough, shortness of breath and severe problems are pneumonia, kidneyfailure and death also. Basically corona virus effects on immune systems and decrease the immune power. There areno specific treatments or vaccines for this disease still now. So in this condition, people have to maintain immunityand should increase immune power to fight against coronavirus. Only washing hand and wearing a mask are notenough to fight against this virus, people have to modify their daily diet. This article summarizes the immuneboosting therapeutic diet against coronavirus (COVID-19).
今天,冠状病毒的新闻登上了所有报纸的头条。冠状病毒正在从中国中部城市武汉的动物市场蔓延。冠状病毒有几种类型,但都不危险,但这种新型冠状病毒非常危险。它是一组引起动物和动物对人类各种疾病的RNA病毒。在中国中部城市武汉的活体动物市场发现的这种新型冠状病毒的有效性,在一系列动物中传播,并在动物与动物之间传播,也在动物与人类之间传播,这被称为溢出。冠状病毒的轻微症状是咳嗽、呼吸短促,严重的问题是肺炎、肾衰竭和死亡。基本上,冠状病毒会影响免疫系统,降低免疫力。目前还没有针对这种疾病的专门治疗方法或疫苗。所以在这种情况下,人们必须保持免疫力,应该提高免疫力来对抗冠状病毒。仅仅洗手和戴口罩不足以对抗这种病毒,人们必须改变日常饮食。本文对增强免疫的治疗性饮食进行综述。
