With the modernization of electronic machines, the size or weight to efficiency ratio is getting small enough to leave the equipment highly thermally stressed. To manage this stress, an experiment on thermal effects of a two-metal (Cu-Ag) micro heat pipe (TMMHP) of convergent-divergent cross section, which provides variable conductivity and pressure gradient, at steady state are investigated to compare with a single metal micro heat pipe (SMMHP). Internal fluid flow is considered as one dimensional which is axially flowing. It is a 150 mm long convergent-divergent hollow circular tube having a hydraulic diameter of 3.74 mm and thickness of 0.3 mm. The evaporator and condenser sections are made of pure copper and silver respectively while the adiabatic section is made of both copper and silver. Water and three low boiling point liquids ─ ethanol, methanol and iso-propanol ─ are used as working fluids. In view of the real situation of machines usage, tests are conducted by placing the heat pipe at three different inclinations of 0o, 45o and 90o. To provide heat flux, an electric heater-coil has been wrapped around the evaporator simulating the heat-generation within an actual device, and simultaneously the condenser section is directly cooled by ambient water in an annular space. Ten calibrated K-type thermocouples are installed at different locations ─ five of them are to measure the temperatures of internal fluid and five are used to measure the surface temperatures of the tube. Temperatures are monitored by digital electronic thermometers. Unlike in the SMMHP, it is found that the super heater effect in the evaporator of TMMHP simplifies the initially developed complex two-phase flow into a single-phase of super heated vapor. Thus, it increases TMMHP’s heat transfer capability several times higher than that of a SMMHP.
We have developed certain definite integrals involving Hypergeometric functions. This integrals are new.
One of the problems facing most third world, developing and or underdeveloped countries including Nigeria today is corruption. This to a large extent affects development. In Nigeria for example, this problem has become endemic such that the entire fabric of the society is affected. Past administrations be it civilian or military had in the time past, put in place machineries to curb and or curtail this menace. Presently, there are institutions established with the sole aim of eradicating corruption. Yet, the disease has refused to go away or die. This is due to the fact that the apostles of this crusade against (corruption) are in most instances affected by it. Corruption is an ethical and moral problem not subject to a consistent theoretical construct, because it varies from place to place, time to time, culture to culture and with the level of development in given country. While one can say that corruption is a global phenomenon, the degree of corruption varies. For example, the incidence of corruption is less in developed countries with good welfare system; it is high in countries and or less developed economies with poor welfare system and income. It is less in socialist countries than in capitalist countries.
Vascular Innovation science are a standout amongst the most approaching innovations which is very secure. In this paperi introduces a study of machine learning techniques utilized for Vascular innovation development applications, and distinguishes significant exploration issues. Basic mission assets and applications require instruments to recognize when honest to goodness clients attempt to abuse their benefits; unquestionably biometrics serves to give such administrations.
Krishi Vigyan Kendras (KVKs) are organising training programmes with the felt needs of the tribal farmers as per the resources available. The study conducted with 240 tribal farmers and farm women undertaken training at KVK in the districts of Sundergarh, Keonjhar and Nuapada revealed that there was overall increase of 36.82% of the knowledge level of the respondents on various farm activities. However, 33.00% gaps indicated that the tribal farmers and farm women were still lacking adequate knowledge. More gaps were observed on farm forestry, fish farming, income generating activities, farm mechanisation, animal production and horticulture in comparison to crop production. Socio-economic attributes of the respondents had not much influence in increasing their knowledge level. Hence, KVKs have to organise more need based training programmes to enrich knowledge and skill competency of the tribal farmers to adopt the changed practices for more production and income for their sustainable livelihood.
This study aimed to investigate the application of the industrial sector companies for the management accounting concepts during the preparation the budgets that recognized by the managerial accounting. Where the main budgets in the management accounting concepts are: Master budget, Financial Budget, Cash-Flow budget, Static budget & Operational budget, but the researcher except the Static budget in this study because it uses for the public and nonprofit sectors, and this study aims to investigate the Industrial sector in ASE-Jordan and all of these companies are profitability.
Background: Use of contraceptive methods is one of the efficacious interventions that help to prevent HIV transmission and unintended pregnancies among HIV positive women. However, contraceptive utilization, in general, and Long Acting and Permanent Contraceptive (LAPM) methods, in particular, and its integration with HIV treatment services is not well understood in poor-resource settings. The study aimed to assess the level of integration of LAPM with ART, LAPM utilization and associated factors among HIV positive women in public hospitals of Tigray, northern Ethiopia. Methods: A cross-sectional study was conducted in 2013 among 343 HIV positive married women selected using two-stage cluster sampling.
This paper proposes a farming environment observing framework for checking data concerning an outside by using Wireless Sensor Network (WSN) innovation. The proposed rural environment observing server framework gathers natural and soil data on the outside through WSN-based ecological and soil sensors. In this paper we are using sensors as soil moisture sensor and temperature sensor .This sensors help the field to control the water level and also temperature .Here we are using wireless sensor network as GSM (global system for mobile communication).
The primary concern of this paper is to argue that Mongo Beti is very political in his search for liberty in the choice of his pseudonyms, the names of some of his major characters and, consequently, his fiction. Before he discovered the hypocrisy in the practice of assimilation, Alexandre Biyidi Awala did not see himself as different from the real Frenchman. When the dawn of realization came, withdrawal syndrome showed. Thus, the French intellectual still lurking in the Cameroonian Biyidi, informed him to adopt a pseudo-identity to be able to express his disgust with a system that enslaved him for a long time. This search for a second, concealed personality yielded a set of symbolically charged names: Eza Boto means “the alienated people” or people without any “authenticity or autonomy”. Mongo Beti, “the son of soil, the child of Beti land. These names tell us what Biyidi thinks of the system he represents in his fiction. This view is highlighted in this paper by examining Beti’s fiction, paying particular attention to the symbolic significance of the names of some of his major characters. This is done with a view to corroborating Es’Kia Mphahlele’s contention in his The African Image that every creative writer must be committed to something beyond his art, to a statement of value not purely aesthetic, but to a criticism of life geared towards liberating a people (VI). This paper therefore, opines that literature, in its critical realist tradition, contributes immensely to the freedom (liberty) of man.
Waste is unnecessary for any kind of industry because it raises the manufacturing cost of products. For owners or clients waste is anything that cannot create any value. By effective lean production system it becomes possible to decline the generation of wastes and increase the productivity in any industries. So, it became very significant to identify lean wastes and its effects on productivity and manufacturing cost of RMG products. By this research work it was possible to categorize the lean wastes in four RMG industries. Motion studies during manufacturing also helped to bolstering the work. Strong willingness of management of RMG industries for increasing productivity and lowering the wastes level accomplished the study successful and finally seven dead wastes were recognized. According to lean manufacturing these dead wastes encompasses overproduction, more waiting time and bottlenecks, over transportation, excess inventory, more processing (re-works), excess motion and defects. These lean wastes could not contribute in adding value of different products. However, this research paper mainly underscored on seven lean wastages of RMG industries and its consequences for increasing production cost and hindrance of productivity due to greater production time.
