Abstract: This is a quasi-experimental method of research aimed to create electronics gadget voltage time delay device for protection of electrical appliances from power spike due to brownouts at affordable cost. Result showed a fluctuation of voltage, current, and power but is ideal based on the three percent voltage drop in a line. The mean temperature for the three treatments in all replicate was normal base on the maximum temperature of the magnetic contactor which is 1000C. The device was used for electronics instruction where the performance of the students was improved based on the pretest and posttest scores. The reliability of the test based on the posttest result was 0.75 interpreted as good which means that the assessment instrument is good; however, there are probably few items which could be improved. Testing the hypothesis of no significant correlation between the pretest and the post test at 0.01 and 0.05 levels of significance, researcher failed to provide sufficient evidence to accept the null hypothesis. The knowledge and skills obtained by the students on the different processes involved during the fabrication of the device can help to engage entrepreneurial activity to augment poverty alleviation.

Search and creation new biologically active compounds which exhibit diuretic action is an current task of the modern Medical Chemistry. In order to identify diuretic activity a series of 5-substituted of 1,3,4-thiadiazole have been investigated. As index of urinary intensity the amount of urine was considered allocated by animals for 2 hours in terms of 100 g of body weight. In determining the diuretic action, a hydrochlorothiazide was selected as a comparative preparation. Screening research which have been conducted together with the study of the effect on the excretory renal function showed that the synthesized compounds exhibit diuretic activity, competing with the comparison standard. The comparative analysis of the biological action of 5-substituted of 1,3,4-thiadiazole and the preparation "Hydrochlorothiazide" showed that the most active among these compounds are derivatives with code 1.1 and 2.2, which significantly exceed the diuretic effect of the reference medicine. The prospectivity and feasibility of further targeted synthesis of this class of substances has shown to create more effective and safe medicines with diuretic action

Abstract: The brewing industry in Nigeria appears characterised by a lot of rivalry in its struggle for dominance. In a bid to gain and retain their market share, the firms have adopted product innovation as a strategy. Unfortunately many of the new products seem not to survive long in the market. This study therefore, examined the relationship between organizational culture and innovation in selected breweries in South-East Nigeria. Specifically, it explored the nature of relationship between market culture and product innovation. Survey research design was adopted. Data were collected through questionnaire and hypothesis was tested using Pearson’s Product Moment Correlation Coefficient. The study revealed that there was a significant positive relationship between market culture and product innovation. Therefore, it is recommended that breweries in Southeast, Nigeria, should develop a market culture that focuses more on research and development so as to manufacture innovative products which will survive beyond the introductory stage, withstand competition and satisfy customers taste.

The paper demolishes an old myth which the Soviet Union created after 1945. The myth is associated with the victory of USSR against Germany and its allies in Europe during the Second World War. According to the Soviet Union, the “Great Patriotic War” of 1941-1945, was won because of Stalin leadership and due to the efficient economic industrial mobilization which the Communist GOSPLAN Central Economic Committee imposed on the economy. The Soviet era argument compares the victory of 1945 with the defeat of capitalist Russia in 1917, and claims that the communist organization of the war economy has been very successful compared to the poor organization of capitalist Russia of 1914-1917 period. The reality is different. The USSR was both heavier industrialized and armed compared to the Empire of the Czar in 1914. However the USSR suffered more defeats, human and material losses as well as catastrophes compared to those of the Russian Empire. And these developments occurred as the country enjoyed greater military and economic aid from the US and Great Britain compared to what was granted to Czarist Russia during 1914- 1917. The biggest paradox however is associated with the post-war settlements. The humiliating defeat which the Czarist Empire suffered in World War I -and was sealed with the Treaty of Brest Litovsk signed by Lenin- was never implemented since the Western Allies with the victory of 1918 simply abolished the Treaty. Thus the defeat of 1917 practically did not have a negative outcome. The 1945 victory generated the huge expansion of Soviet sphere of power in Eastern Europe but the cost of victory was so high that the final outcome can be considered as a pyrrhic victory.

The aim of this study is to compare the efficiency of radiopaque dye, decalcification, and histological sectioning in detection of accessory canals in mandibular 1st molars. 30 Extracted mandibular 1st molars were selected. The teeth selected for the study were stored in normal saline. Endodontic access openings were made using a round bur and pulp tissue was removed from the pulp chamber using a standard spoon excavator. Root canal contents were extirpated using barbed broach. Complete debridement of root canals was done using files No. 8 to 25, with copious irrigation using 3% sodium hypochlorite. The teeth were placed in separate bottles containing normal saline and were labeled. Three different methods were used to study the accessory canals, viz, Radiopaque dye, decalcification, and histologic sectioning. According to this study, The incidence of lateral and accessory canals for the mandibular first molar is 46.6%. Results showed that Histological sectioning was significantly ( P = 0.048) better than dye method , but the difference between the Histological sectioning and decalcification was not significant.

The purpose of this study is to predict the accurate timings for pubertal growth peaks for Class I, Class II - Div 1, Div 2 and Class III. Comparisons are made between the period of the pubertal growth peak in Class I, Class II –Div 1, Div 2 and Class III subjects. This would help the orthodontist in the following ways: 1) For predicting correct treatment time for all malocclusions. 2) For benefiting the patient by guiding the growth modification treatment during the favorable time in a balanced and harmonious manner. 3) To assess skeletal age and pubertal growth spurts are of prime importance in orthodontics and dentofacial orthopedics, for diagnosis, treatment planning, and retention. This study has used the Cervical Vertebral Maturation (CVM) technique for the finding of the peak in growth of mandible, based on the scrutinizing and analysising of the second through fourth cervical vertebrae in a single cephalogram. The lateral cephalograms of orthodontically untreated or new subjects/ patients, ages 8 through 18 years, were studied. The CVM stage on each radiograph was assessed and evaluated according to the Baccetti et al method. Skeletal relationship was evaluated by Steiner’s analysis (By Steiner's analysis: ANB (A point, Nasion, B point) shows whether the relationship amongst the maxilla and mandible is normal (skeletal class I relationship (+ 2 degrees), a skeletal Class II (+4 degrees or more), or skeletal Class III (0 or negative). The Duration of pubertal peak in Class I was 5 months longer than class II patients and 6 months shorter than class III patients. The pubertal peak for Class I subjects lasted 1 year 4 months (in agreement with previous indications of the literature) whereas in subjects with Class II div 1& div 2 malocclusion it lasted for a shorter period (11 months) and Class III malocclusion it persisted for a longer period (1 year 10 months).

The right to education is a fundamental right enshrined in the most important legal documents and international conventions. Nevertheless in countries with ethnic and linguistic divisions, the right to education is not guaranteed to all and often it is required a genuine implementation of policies in order to achieve inclusiveness and full realization of this right. In this paper I will analyze how this right is implemented when it comes to national minorities in the case of FYR of Macedonia. In the first part of this paper I will compare the educational system before and after the Ohrid Agreement, to find the root causes of the segregation of pupils with different ethnic background in Macedonian schools today. This phenomena lead to the necessity of a new approach when it comes to education in divided societies: that of inclusive education. The last chapter will discuss specific policy suggestions in order to overcome barriers to the inclusiveness in education. In this paper I will mainly use secondary sources such as reports and studies published by international and regional organizations. Primary sources will be also consulted such as the Macedonian legislation on the educational sector from 1991.

Unemployment is one of the main problems facing Algeria, due to their negative dimensions and serious consequences on the country’s economy and social life. Therefore, Algeria government has developed policies of employment concerning the category of young people; especially university graduates. This is resulting in a new version of labor, temporary labor instead of permanent labor; that represents an essential mechanism for integration and social cohesion. The objective of this paper is to investigate labor representation of the young university graduates category rather than their ambition realized from temporary labor. In this study, a conceptual framework is developed based on extend literature review and examination of data collected from 60 young university graduates working in public sector. Globally, there is a difference between female’s and male’s labor representation. Female labor is a way to self – realization and appreciation in the first confederation and them a means of financial independence. While for the male labor is festival way to salary then an obligation for society services. As a result of their ambitions, temporary labor may help to absorb unemployment rate especially for university graduate.

Pemphigus vulgaris and mucous membrane pemphigoid are uncommon dermatological disorders which also involves the mucosae of the oral cavity. Both the conditions differ in microscopy and prognosis. Thus the aim of the present paper is to present one case each of pemphigus vulgaris and mucous membrane pemphigoid with oral involvement. Special attention has been made on the clinical tests to evaluate these disorders and cytological pitfalls, which may be helpful for both clinicians and pathologists.

Current methodologies in displaying dynamic organic frameworks regularly need fathomability, particularly for users without scientific foundation. In this paper propose another way to deal with defeat such confinements by joining the graphical representation gave by the utilization of Petri nets with the demonstrating of flow by effective yet natural fuzzy logic based frameworks. We build a fuzzy reasoning Petri net (FRPN) model for the genetic regulatory network of the lac operon of E. coli bacterium. Depending on the FPN formalism is a decent other option to mathematical equations that require dynamic parameter qualities and better than Boolean Formalism which naturally sets control as "on" or "off" guidelines. The lac operon has been considered as a model framework for comprehension the molecular biology of gene expression with considered to its regulation. We approve our formal model via programmed checking a progression of characteristics that are known for the control of the lactose. In this way, we demonstrate the feasibility of utilizing FRPN to design and reason about biochemical systems.

Completion of root development takes around 3 years after eruption of permanent teeth. Any pulpal injury in this period can lead to necrosis of pulp. Pulp necrosis of immature permanent teeth may impair root development and apical closure of root canals. Management of immature non vital teeth is very challenging for a clinician because teeth may have wide open apex and thin root canal walls that may diverge towards the apex. Conventional cleaning and shaping of the canals and obturation may not be possible because of the lack of apical stop. This case report presents two cases of apexification. First case, managed using Calcium hydroxide and iodoform paste for multiple visit apexification which had a rare apexogenesis like outcome and second case using MTA for single visit apexification followed by root reinforcement with Glass fiber reinforced composite post.

This review was indicated on healthcare development of Cambodia and Kazakhstan. This paper aimed to comparison studies on healthcare system between Cambodia and Kazakhstan. The healthcare system of these two countries is significantly different, and healthcare reform in Kazakhstan was just a little better than in Cambodia; although, the health situation in both countries was virtually the same, and needs the government to improve more on this sector. The MOH is the principal authority who has overall responsibility on this sector, and strongly assures this sector has been improving. In suggestion, to enhance this sector, MOH should be watchful on policies, legislation, strategic plan, financing and increasing health workforce.
