To shift wave-vector k as well as Hamiltonian from traditional (100) plane orientation, tensor plane revolution equations are used. It is demonstrated that optical emission spectrum and crystal plane alignments have a significant correlation. At a carriers injection density of 2.50 x 1018 per cm3, the maximum and minimum gains are measured in the (111) as well as (100) orientations, respectively, with optimum emission wavelengths of 1770.00nm and 1680.00nm.

Common aims are to increase strength or stiffness or to reduce permeability within the mass of ground treated. This paper, mainly, addresses permeation grouting for the improvement of soils, in terms of strengthening or reduction of permeability, and compensation grouting for the displacement of structures during subsurface exploration. The grouts used to make permeation grouting are suspensions and chemical solutions. The suspensions penetrate well into soils with granulometry up to coarse sand. On the contrary, the chemical solutions penetrate satisfactorily in finer formations up to fine sands or coarse sludges. Because some chemical solutions are toxic or generally harmful to the environment and humans, an effort has been made internationally in recent years to replace them with inorganic fine-grained suspensions.","PeriodicalId":8524,"journal":{"name":"Asian Journal of Engineering and Applied Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84659779","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 inorganic salts used were NaCl, KI, and MgCl2·6H2O. The influence of factors such as amount of salt, phase volume ratio, initial aniline concentration in feed-water solution, and temperature on the distribution of aniline was investigated. It was found that addition of 5% NaCl shows an appreciable salting-out effect on distribution of aniline. It was also found that the distribution of aniline was favoured at low aniline concentrations, and a phase volume ratio of toluene to water of little above 1.0. It is also found that the dissociation of salt added plays an important role in aniline extraction and the effect of cation and/or anion as predicted by the Hofmeister series may not be always followed in all cases. The distribution of aniline between water and toluene is found to be endothermic in nature.","PeriodicalId":8524,"journal":{"name":"Asian Journal of Engineering and Applied Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87427245","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}

In the current project, this optical characteristic of CdO nanoparticles is used to time investigate of interaction between different aryl mercaptanes and CdO nanoparticles. The results were shown that aryl mercaptan compounds with shorter chain length interact faster with CdO nanoparticles.

Packet data is a method of transferring data, broken into bits called packets which travels over a network. Packet losses occur when packets fail to reach their destination devices as a result of network congestion, faulty routers or as a result of an attack. Encryption is the standard method for making a communication private. In sending a private message to another user, it is first encrypted (termed encipher), the intended recipient alone knows how to correctly decrypt (decipher) the message. There are several algorithms developed for the purpose of encryption which provides data security and integrity. This paper proposes the use of the Rivest-Shamir-Adleman (RSA) algorithm to implement a system for encrypting text files of any length (by breaking long messages into valid blocks and encrypting each block) capable of being transmitted using a Simple Mail Transfer Protocol (SMTP). Probable primes, 3048 bits in length are generated to be used in the generation of public, private key pairs for encryption and decryption. The proposed scheme is better because the route taken during transmission of data is recorded and packet losses are also checked for during transmission of encrypted files as compared to known state-of-the-art schemes.","PeriodicalId":8524,"journal":{"name":"Asian Journal of Engineering and Applied Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86493596","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 shelf life of vegetables is highly dependent on temperature and humidity in storage place. Cold room and refrigeration facilities are out of budget due to advance technologies and high electricity consumption. Affordable storage facility is highly useful in such conditions. The paper aims at developing low cost, small scale evaporative cooler that operates on a principle of evaporative cooling phenomenon. The developed model has box type of structure having water holding vessel at bottom side. The proposed model has cooling fan arranged for vertical orientation with certain height partial closed as well as medium height between cooling chamber and storage chamber. The fan has been operated at two speed variants namely low speed as well as high speed for getting results at different evaporation rates. Throttling vanes have been provided through the air entering chamber which significantly affects evaporation capacity of the evaporative box. In the given range of 270 minutes of operating time during two time slots i.e.,morning and afternoon. Humiditypercentage increase from 26 to 60 is found through the experimentation while the temperature difference was reduced down to 8 degrees of difference (40 ⁰C to 32 ⁰C) through experimentation. The performance of the developed model was found better in case of throttling with fan speed parameter that includes partial throttling at high speed and medium throttling at low speed.","PeriodicalId":8524,"journal":{"name":"Asian Journal of Engineering and Applied Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91026993","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}

Information and communication technology is an opportunity for young individuals to grow businesses. Young professionals need to investigate in small and medium-sized enterprises and should not only expect to get jobs elsewhere. The issue is that young professionals in the East African community cannot compete with each other when their mindset on doing business through small and medium-sized enterprises are taken differently and the levels of economic of these countries are very different. This article is motivated by the researcher’s observation analysis about young professionals in the East Africa community who know information and communication technologies, and unfortunately, they use them in a way that cannot make small and medium-sized enterprises successful. The main goal of this study is to describe information and communication technologies as an opportunity to buy or sell goods or services through small and medium-sized enterprises. This study will provide a better understanding to the lecturer, especially young professionals to take information and communication technologies positively as an opportunity to grow business through small and medium-sized enterprises and to know the strategy to use to sell products and how to manage consumer’s behavior through their needs.
