 Abstract

Background: Histopathological examination still remains the gold standard method for the confirmation of the appendicitis. Patients with incidental findings of tumors and parasites, do not present with the specific symptoms and hence, elective or incidental appendectomies are performed. Aims: To determine the various histological diagnoses of all surgically removed appendices and to find out the age and sex related incidence of appendicitis, the perforation rate and the rate of elective or incidental appendectomies. Methods: This was a cross sectional retrospective study at a tertiary care centre of 1043 appendectomy cases over two years period. Results: The mean age was found to be 29.13 years. In present, males (51.7%) slightly outnumbered females (48.3%), with male to female ratio of 1.06: 1. Most common non-neoplastic lesion was acute appendicitis (51.8%), followed by chronic/ recurrent appendicitis (31.6%). Neoplastic lesions included eight metastatic Adenocarcinoma � six from colon (0.6%) and two from ovary (0.2%). Carcinoid tumor was found in 0.2% cases and Primary Mucinous Adenocarcinoma was seen in 0.1% cases. Limitations: This was a retrospective study hence the follow-up of patients could not be done. Conclusions: Present study strongly emphasizes and recommends meticulous gross as well as microscopic examination of every appendectomy specimen.

 Abstract

Honeycomb structures are often natural or artificial assemblies, which have the similar geometrical shape of a honeycomb and are used to get the expected strength by minimize the amount of used material, reduce the weight and cost of the materials. The advantages of honeycomb sandwich structures when compared to conventional structures are that it provides: very low weight, production cost savings, durability and high stiffness. Acrylic Honeycomb structures are made-up of unique core material that offers advantages such as good impact strength, transparency, resistance to breakage, elasticity, good weatherability, good heat resistance, excellent dimensional stability. Honeycomb sandwich composite fabricated by using Acrylic honeycomb sheet as a core material along with carbon fiber reinforced polymers (CFRP) and glass fiber reinforced polymers (GFRP) as face sheets. The main objective of this paper is to evaluate the Flexural strength of Honeycomb sandwich composite and calculate the values from the Python Libraries such as NumPy and Matplotlib.

 Abstract

The E-commerce business levels are every day rising, people are getting adopted to using on the web and composing remarks about their buy encounters on seller/audit Websites. These obstinate substances are gainful to both future purchasers for essential initiative and to sellers to enhance their products and moreover organization. To lighten this issue, numerous data mining approaches are designed which uses human efforts. Today, deep learning has risen as a powerful method for classification problems. We propound new deep learning system WDE that could use the huge amount of pitifully sorted audit reviews for the sentiment analysis. WDE attempts to catch the assessment circulation of the information by inserting preparing on pitifully marked sentences. At that point, it utilizes a couple of marked sentences for profound system adjusting just as for forecast model learning. In this system first, we train the data by CNN-WDE Classifier and then view the features vector. After that Detect the Sentimental labels. Then perform the classification and we can get the exact positive or negative view in the Sentiment Prediction Graph. To assess the proposed framework, we took a dataset containing unlabeled reviews from Amazon.

 Abstract

This paper attempts to study the nature of the modern education process in India where diversity is seen economically, financially, socially and geographically not only in culture and ethnicity but also in purchasing power and affordability of the Indian people. The imposition of lockdown due to Covid-19 spread in India which has continued till today, promoted the e-learning process facilitated by digital instruments like Laptop, Smartphone, flash drives etc with the aid of several apps like Zoom, Skype, Google Meet etc. Institutes and enterprising teachers try to market e-learning among their students. For A-level and B-level cities its good and sounds very elite. However the areas with low connectivity and those belonging to underprivileged sections or living in far-flung areas that cannot afford data plans and other gadgets and drives it�s another divide. These students are staring at the electronic divide that this new turn of digital education has brought them. As destined to be the electronic media inequality is staring and creating class privileges so the real world and the virtual one all have class privileges. So, while many universities and colleges are conducting online learning sessions, students from disadvantaged families or living in remote areas might not have access to Telegram, iCloud or, indeed, the internet even in the best of times. The paper uses secondary data from the published Government sources and websites and other data from cited papers. It is a descriptive study. This discussion paper brings forth the limiting aspect of Electronic Education various limitations the Digital Education has landed us on. An attempt is being made to explore the electronic divide that exists in India and bring to the discussion the infiltration of internet and, its use, applicability to the day to day needs of education by the people in India; also the initiatives under the ambitious Digital India Program is highlighted in the paper to find out India�s progress in transforming itself into a digital society.

 Abstract

The thesis focuses mainly on well efficient model of high frequency range, low power and high stability all pass filters. In vision of the modern communications there is a progressive development in the signal transmission techniques in sight of the contemporary methods arise to transference the signal from source to destination by means of the transmitters and receivers, as the par expansion of these systems is more, transreciever has to be replaced both and in designing such complex model a number of suitable considerations are come into account like filtering the signal and passing the signal form Hz to several GHz mainly for the RF, military application and also for wireless communications. To accomplish the task for building an effective such a novel design is required for the processing and passing the sustainable measured quantity without any loss of the information and its characteristics are to be analysed for the accuracy and efficiency. In context of these a physical variable is needed for such type of realizations, and from these aspects an all pass filter design here provides all the features like gain, stability and phase, The implementation of the all pass filters is worked out with different methodologies and the selection of the topology for the high range frequencies are somewhat critical to validate. The models proposed accompanies the ideal characteristics of Analog all pass filter such as unity gain, high bandwidth and 180� phase shift over the band of frequencies with supressed noise and high efficiency.

 Abstract

Additive manufacturing is the industrial production name for 3 D printing, a computer controlled process that creates 3D objects by depositing materials usually in layers. Using computer aided design (CAD) or 3D object scanners, additive manufacturing allows for the creation of objects with precise geometric shapes. Additive manufacturing processes take the information from a computer-aided design (CAD) file that is later converted to a stereo lithography (STL) file. These are built layer by layer which is in contrast to traditional manufacturing that often requires machining or other techniques to remove surplus material. Additive manufacturing has introduced a novel method in design, manufacturing, and distribution to end to end users. This technology has provided great freedom in design for creating complex components, highly customizable products and efficient waste minimization. This paper mainly concentrates on raising the importance of additive manufacturing and how additive manufacturing has advantages over conventional manufacturing process. Additive manufacturing has revolutionized the production industry by providing Freedom of design; less wastage of raw material, the desired product can be manufactured by adding materials of desired properties. The additive manufacturing includes VAT polymerization, powder sintering, hybrid, 3D printing, metal extrusion, Sheet lamination, metal jetting, Direct energy deposition..

 Abstract

Pulmonary breathing sounds act as the important indicators of respiratory tract health and respiratory tract disorders. The breathing sound emitted by a person is directly related to air movement, changes within lung tissue and the position of secretions within the lung. For instance a wheezing sound, is a common sign that a patient has an obstructive airway disease like asthma or chronic obstructive pulmonary disease (COPD). Pulmonary breathing sounds can be recorded using digital stethoscopes and other recording techniques. This digital data provide and des us with the possibility of using the deep learning technique CNN to automatically diagnose respiratory disorders like asthma, pneumonia and bronchiolitis, etc.
