 Abstract

The purpose of acid etching is to remove the smear layer and create a rough surface by mixing hydroxyapatite crystals on the outer surface. This topography will facilitate penetration of the fluid adhesive components into the depressions created; hence the adhesive gets locked into the surface and contributes to micromechanical retention. If a laser can achieve the above-mentioned function of acid etching, and even produce a desirable surface for bonding to a restorative material, it may be a viable alternative to acid etching. The purpose of this study was to compare the bond strengths after acid etching with conventional primers, acid etching with moisture insensitive primers, laser etchants with conventional primers and laser etchants with moisture insensitive primers

Pityriasis alba is a common fungal infection of the skin in tropical region. The characteristic lesions are small yellowish-brown macules. These slowly blend to from large disfiguring area. Concomitant hypopigmentation is usual. Most of us get confused in diagnosing pityriasis in an initial year of practice and thus we need to know the differentiating characteristics of condition. However, treatment can be possible of the homoeopathic medicine through proper repertorization and totality of symptom. A 14-year boy came to OPD with complaint of white rounded patch on right cheek and forehead from last 3 months. Appearance of the patches are lighter than the surrounding skin. Headache aggravate from heat of sun and ameliorate from cold things.

 Abstract

This study is a theoretical paper aimed at looking at issues, challenges and the way forward concerning agricultural development and employment generation in Nigeria. Nigeria as an economy is endowed with too many resources both human and natural. Yet there is still threat of poverty, starvation, insecurity and unemployment. The unemployment rate is so alarming that between the periods of 2010 and 2019 the rate stood at 5% and 23.1% and a projected 33.5 in 2020. This is a worrisome status as Nigeria serves as the global poverty capital with the incidences of high prevalence of crime rate, murders, kidnappings, militancy, armed robbery, drug abuse and many other vices. To combat this menace calls for urgent attention. It is in the light of the above this study is carried out to access the level of development in the agricultural sector and unraveling the potentials and capacity of the Nigeria agricultural sector if properly developed in generating jobs for the millions of people (Nigerians) without jobs. However, in the course of this study, poor agricultural funding, poor and lack of farm inputs, inconsistent and no sustained policy and programmes for the sector, lukewarm and lackadaisical attitude of political leaders and neglect of agricultural research institutes are seen as some major issues hampering the development of the agricultural sector in Nigeria, Furthermore, the study revealed that the agricultural sector is the most critical sector that has the potential to industrialize Nigeria, reduce poverty, increase food security and create jobs for the massive unemployed population. The study concludes that the development of agricultural sector is still at its infant age despite the numerous policy efforts of successive government to develop the sector. Therefore, it is suggest that the only way forward for Nigeria agricultural sector to drive industrialization, guarantee food security and employment generation is by total and massive investment in the sector, budgetary allocation to the sector should be increased by 10% to meet 2003 African Union Summit in Maputo and the right policy and programmes put in place, sustained and managed by patriotic states men and women for the benefit of all.

The problems which are related to our basic needs may be common. But certain problems are specific to ageing. But while ageing has a charming beginning in the form of development (i.e. growth and differentiation), it has a dismal end marked by senescence, loss of adaptability of the organism to its extrinsic and intrinsic environments, decrepitude and ultimately the macabre death.

Wireless location is defenceless to malevolent assault owing to the scenery of its unlocking intermediate. These lessons propose an attack-resistant fingerprinting localization algorithm bottom on a probabilistic comprehensive disjunction representation. This representation allows an assault surveillance to play a fewer momentous role throughout the localization procedure, thus attain additional healthy position opinion beneath safety intimidation. This learns built-in experiment conduct in a real Wi-Fi system. Untried consequences well-known that this move toward them says that achieve more robust judgment than cluster-based, median-based, and sensor-selection technique beneath a mixture of show aggression on RSS.

 Abstract

The effect of doses of black pepper, black cumin, garlic and methi powder against pulse beetle and recorded the highest adult mortality (83%), lowest number of eggs (42%), numbers of adult emergence (11.11%) and amount of weight loss (29.00 %) when gram seeds were treated with black pepper powder at 1.00 g/kg. The efficacy of four plant extracts viz., Clove, Sehjan, Ajwain and Ginger against Fusarium solani at 10%, 25% and 50% concentrations. Among all four plant extracts tested, Clove was found to be most effective against Fusarium solani on Third, Fifth and Seventh day at 50% concentration and conquered the colony growth by 100% compared to control. Different bacterial species and the amount of clove oil used and observed that Ralstonia solanacearum was the most sensitive when 50 ?l of clove oil was used in our agar diffusion assay. Tomato and Geranium plants grown in R. solanacearum-infested soils pre-treated with 0.5% clove oil were significantly taller and produced significantly more root and above-ground plant tissues than their untreated control. Geranium plants grown in R. solanacearum-infested soils treated with 0.5% clove oil produced similar number of flowering stalks to those in bacterium-free soil with or without clove oil treatment.

 Abstract

Diabetes is a group of metabolic diseases that is due to a high level of sugar in the blood for a long period of time. People with diabetes are also more likely to have many other conditions to raise the risk of heart disease. Diabetes and heart disease are the two most complex diseases that are globally affecting many peoples in society. According to WHO, the report says the diabetes patients list has been increasing day by day and due to diabetes 1.6 million deaths was caused in the year 2016 and by 2030 approximately 700 million peoples will be affected by diabetes worldwide. Therefore early prediction of diabetes is very necessary for that Data mining has played a main role in the field of diabetes and heart disease research. The main objective of this paper is to predict diabetes and heart disease which help doctors and many other medical practitioners to predict the disease before it occurs.

 Abstract

Projects within the development sector is characterized as fragmented, temporary and sophisticated which inherently brings upon risk exposure. Decision makers within the industry need reliant access to information and knowledge so as to manage risks during a sufficient and systematic way. Thus, the implementation of an efficient risk management in reference to managing associated project risk knowledge may facilitate successful construction project endeavors. The purpose of this master thesis is to explore and evaluate project risk management within the Swedish housing industry, with the stress on the attitude of Swedish contractors. The aim is to look at the popularity and practical adoption of risk management so as to investigate how project knowledge is employed within the process. The methodology consists of a literature review on risk management fundamentals, the various risk attitudes and knowledge management in reference to risk. Data collection and analysis are based on a mixed method approach during which conclusions are made in reference to theoretical groundwork. The empirical data is collected through the usage of a web survey and in-depth semi structured interviews with key professionals within the Swedish housing industry. The results from this research indicate that theoretical models and processes for risk management is fairly unknown within the industry, analogous methods are used within respective organizations but the sharing of definitions and ideas within the industry are absent and therefore the methods aren't as structured as described in risk management theory. However, findings suggest that the perception of actors within the industry regarding risk and therefore the risk management process is one among high importance for obtaining project objectives. Furthermore, findings indicate that the interplay between knowledge- and risk management and therefore the incorporation of those processes is underutilized among the contractors and developers.

 Abstract

Due to rapid industrialization, the waste products are also being generated in huge quantity which occupies large quantity of precious land as well as creating environmental problems. Recycled Concrete Aggregates (RCA) which is generated as a part of Construction and Demolition material is a type of waste product. In the same way, Blast furnace slag is also a waste product of steel production. As the construction of pavements requires a massive amount of aggregates, the replacement of part of fresh aggregates with mixture of Recycled Concrete Aggregates (RCA) and Blast furnace slag will be very advantageous considering the dearth of fresh aggregates. Therefore, an attempt has been made in the present study to determine the optimum proportion of Recycled Concrete Aggregates (RCA) and Blast furnace slag as Base material in pavement. The main objective of the study is to select the best possible percentage to increase the bearing capacity of sub base granular layer. The cost of construction of the pavement is considerably decreases if locally available low cost materials are used in the construction of sub base, sub grade etc. The design of pavement is based on the minimum specified structural quality of the soil that will be achieved for each layer of material. Each layer must resist shearing and avoid too many deflections that cause fatigue. It is also used to decrease the compressibility and permeability of the soil mass and to increase its shear strength. As the quality of the soil is increased, the ability to distribute the load is increased so that a drop in the thickness of the soil is also permitted. Use of by- products is also a way to protect environment from the harmful effects of recycled aggregates and blast furnace slag as they are required to be dumped in open grounds or beneath the surface which affects the natural formation of the soil and degrades the surface. In this research various laboratory tests like atterberg limits, proctor test and CBR i.e California bearing ratio test is performed and the best possible combination of the required proportion is selected.

Gone were the days where the traditional technique of recruitment would suffice to appoint potential talents. But, for a long time, the recruitment system has witnessed a sea of alternate due to the introduction of the web and its proliferation. Earlier the organization had the power all through the job search, however in the current trend; candidates have a ways greater power in the course of the job search. The potential candidates had been viewed to be the employee in the past, however, the whole center of attention has modified and the candidates are being handled as customers. This dramatic change is all due to the altering phenomena of the web and its tremendous coverage in growing countries.
