ROLE OF PROBIOTICS IN GASTROINTESTINAL TRACT DISEASES: INFLAMMATORY BOWEL DISEASE AND NECROTIZING ENTEROCOLITIS

Bacterial microflora which is present in gastrointestinal tract cause various disorders. Probiotics provides beneficial effects in gut related disease. Previously probiotics are used as alternative medicine but now entering in mainstream medicine. Probiotics help in restoring normal bacterial microflora and regulate the gastrointestinal tract functioning through different mechanisms. There are only few evidences available which show potential benefits of probiotics. The efficiency of probiotics used as a single strain or multiple formulation is tested in various diseases such oral health, diabetes, multiple sclerosis, inflammatory bowel disease, necrotising enterocolitis and many more. The purpose of this paper is to focus on diseases related to gastrointestinal tract including inflammatory bowel disease and necrotising enterocolitis based on the literature review available and propose future perspective to reduce the translocation of bacterial microflora in gastrointestinal tract and reducing subsequent inflammation of gut.

System on Chip based Design of a Prototype Unmanned Sea Surface Vehicle

This paper discusses regarding design and developmentof a simple, low cost, the prototype of an UnmannedSea Surface Vehicle (USSV). Prototype USSV using System onChip(SoC) can be developed which could be used for carryingout surveillance at sea and underwater survey operations.Afterimplementing autonomous control system this vehicle can be usedfor more complex operation such as Intelligence Surveillance andReconnaissance (ISR) operations. This vehicle is developed basedon centralized architecture, System on Chip (SoC). Interfacingcircuits using analog components are designed so that inputoutputdevices can be reliably interfaced. Interfacing Software,Communication Protocols, and the Remote control panel isdesigned and developed for the prototype USSV. Selection ofoff the shelf navigation and Instrumentation sensors, Thrusters,Communication systems and Payloads with its interfacing isbriefly explained in the paper. Finally tests and trial resultsare discussed along with conclusions and further scope forimprovement

MULTI FUSION PATH PLANNING ALGORITHM FOR UGV

This research paper presents the work on the multifusion path planning algorithm for Unmanned Ground Vehicle(UGV), which includes, tasks such as studying various existingalgorithms, combing algorithms for better results,implementing multi fusion path planning algorithm to producean optimal path for UGV in a simulated environment. Todetermine collision free path for a robot from start to goalposition in a workspace comprising of obstacles, is the mainchallenge in the design of an autonomous UGV. The Multifusion Path planning algorithm subsequently attempts tocreate free paths for the UGV to travel in the workspacewithout colliding with obstacles. Probabilistic roadmap (PRM)algorithm along with Dijkstra algorithm is used for the UGVnavigation in an environment. Python is used for simulation ofthe results

Thermal segragation of asphalt material in road repair

This paper presents results from a field study of asphaltic pavement patching operations performed by three different contractors working in total of ten sites. Thermal imaging technology was used to record temperatures of the patching material throughout the entire exercise, from the stage of material collection, through transportation to repair site, patch forming and compaction. Practical complications occurring during patch repairs were also identified. It was found that depending on the weather condition and duration of the travel, the temperature of the asphalt mixture can drop as much as 100oC over the entire period of patching work. Cold spots and temperature differentials were also identified between the new and old surfaces as well as along the edge of the pavement. In addition, the temperature loss at various locations on the asphalt mat was found to vary despite the material being laid at the same temperature. For example, over a five minute period, the temperature at one point was reduced by 33% whereas the temperatures of nearby areas were decreased by 65% and 71%. A return visit to the repair sites, three months later, revealed that locations where thermal segregation was noted during the patching operation had failed prematurely

Seismic Reliability of Highway Transportation Systems

Assessment of the reliability of lifelines under seismic loads requires particular attention, since the proper functioning of these systems during or after a destructive earthquake is very important. The main objective of this study is to investigate the system reliability of lifeline networks subjected to earthquake loads by concentrating on highway transportation systems consisting of viaducts, bridges, roads, and highways. Seismic reliability of a structural component is determined based on the seismic capacity of the component and earthquake loads acting on it. The future earthquake threat on the components is calculated by performing a probabilistic seismic hazard analysis. Failure reasons of bridges and asphalt roads are explained and behavior of these components under earthquake loads is discussed to determine the seismic capacities of them. In this respect, the system reliability concepts are used and bounds on the seismic reliability of a system are established. A case study based on real-life data is also presented in order to illustrate the implementation of the method. (C) 2018 American Society of Civil Engineers
