The use of waste as an additional material on the building work was increasingly actively developed, such as straw, styrofoam, bagasse, cow manure. The key drivers of the use of waste is the potential for waste is increasing, due to the depletion of non-renewable resources. Papyrus rod diameter 60 cm, length 30 meters, has a volume of 5,652m3 as well as the edges of the Rods that can be used for construction with a thickness of 3 cm has a volume 0,942m3, Pith and fiber volume content of the stem 4,71m3/rod, then in one rod, there are 2 to 3 bunches each fruit bunches yield as much as 20 to 30 items for one harvest, by weight of fruit fiber 101.2 gram / fruit, Fiber characteristics are round and smooth is expected to reduce cracks in solid concrete brick and also can reduce the use of sand. This study aims to determine the compressive strength of the composition of the additional material of Rods fiber content and Fiber of palmyra fruit with a percentage 3%, 6% and 9%, mixing ratio; 1 cement and 5 sand in the manufacture of solid concrete brick. Rods fiber content used the average Ø1,031mm with a tensile strength of single fiber 39,305N / cm and fruit fiber to an average value Ø0,40mm with a tensile strength of single fiber 33,691N / cm. Making test specimen with a length of 20cm, width 10cm and thick 8cm.

Abstract

Sterilization of health care products, reduction of total microbial load in feed and food samples, extension of shelf-life of freshvegetables and genetic improvement of some plants are some of applications in the GU-3 gamma irradiation facility. The dosimetricsystem used is treated in this paper because dose and its uniformity are very important parameters of the radiation processing. They arerelated with chemical, biological and other physical changes in the irradiated product. To provide good dose uniformity (determined asthe ratio of maximal dose to minimal dose) it is applied the radiation technique based on the rotation of the vessel with the material insideit. The dose uniformity was about 105 %. With regard to reducing total microbial load in food and feed samples it was seen that thisquantity was reduced from )/g for control, up to &gt;10/g for the irradiated samples. Over analytical controlof the irradiated health care products was confirmed their sterility. Irradiated fresh vegetables (tomato and strawberry) had a longer shelflifethan control. We used mutation breeding in pepper through radiation to improve crops quality and in M1 generation photosyntheticpigments were higher in mutant materials than control.

Abstract

Typhoid fever is a systemic disease characterized by fever and abdominal pain caused by dissemination of S. typhi or S.paratyphi. In contrast to other Salmonella serotypes, the etiologic agents of enteric fever (S. typhi and S. paratyphi) have unknown hostsother than humans. Thus, enteric fever is transmitted only through close contact with acutely infected individuals or chronic carriers.Rather, most cases of disease result from ingestion of contaminated food or water. Over the past four decades, with the advent ofimprovements in food handling and water/sewage treatment, enteric fever has become a rare occurrence in developed nations. Childrenunder 1 year of age appear to be most susceptible to initial infection and to the development of severe disease. Enteric fever is endemicin most developing regions and is related to rapid population growth, increased urbanization, inadequate human waste treatment, limitedwater supply, and overburdened health care systems. Morbidity and mortality are increased in outbreaks associated with antibioticresistantstrains, presumably because of inadequate or delayed treatment. In this article we have considered all hospitalized cases inpediatric department of Regional Hospital of Shkodra, with acute diarrhea. All cases diagnosed as salmonelosis typhoid’s and portablesare diagnosed with culture proven because we don`t effort the serology method cause of expensive kits and provisions) in our hospitals.It is impossible to have this information because the hospital has not the high technology laboratory. It has very old equipments in thecurrent laboratories and we use only the culture proven instead. The elaboration of datas is made by a simple method, descriptiveand cumulative. Some dates analyzed with Microsoft Office Excel method are presented through graphics.

Abstract

The communication teachers –parents is going to be even more essential for the progress of the child. So it tends to be directand all inclusive with the aim of evidencing the progress of the success of the child. The information, is very important in transmitting thechanges and the new ideas in the educational process, as a primary form of communication .This study tends to analyze some problemsfaced in information and as a result in communication parents - teachers. To highlight these problems we have done a questionnaire withapproximately 100 parents of primary and secondary school children, from which we tend to present that the information in our schools isnot in the required expectations, especially in public schools. In non-public schools, in which the information is more formal andinstitutional toward every parent are also evaluated some details and elements as: parents meeting, school activities, tests etc.,consequently the communication is more different in the simplicity, objectivity in evaluation and judgment. On the other hand this studytends to bring different forms of communication, which are applicable nowadays in Shkodra city schools. Also what they suggest to do intheir point of view, what they want from the school, how they want to collaborate with teachers and other staff to be more fruitful andsuccessful for their children.

Abstract

This research aims to study the capacity of Thai local governmental agencies in addressing water shortage causingvulnerabilbities to the local tourism industry on Koh Chang Island. The objectives of the study includes assessing the economic andsocial vulnerability of local tourism industries having been affected by water shortage caused by climate change and to study thecapacity of the local governmental agencies in dealing with the problems. The research design and data collection techniques employedin this research included documentary research, interview, and field surveys. A series of studies were conducted to disclose certaincritical issues of vulnerability caused by water shortage in the study area and to study the current ways that the local governmentalagencies deal with the problems. The study of Yohe and Tol (2002) regarding determinants of adaptive capacity was applied as datacollection framework to create the interview guides and other tools used in this study. Twenty-four respondents in this study comprisinglocal governmental agencies, local community leaders, and local tourism operators. The finding could be concluded that water shortagein Koh Chang Island would come from climate change, but the most important thing is the lack of knowledge on water managementunder the climage change of the local governmental agencies. Therefore, capacity building of local governmental agencies on climatechange and properly water management should be performed in order to reduce water shortage affecting on tourism industries.

Abstract

Shaping Traditional and Modern Approaches to Mitigate Impacts of Mining Industry: A case study of Karen Village, LowerKlity Creek, Thailand aims to analyze the effectiveness of mitigation measures, in the past and at present, for solving the problems ofcontamination of lead in waste water releasing from mines into the creek. Secondly, this project also aims to present mitigate measurethat is the hybrid of traditional folk wisdom and modern technology in solving the problem. The study is carried out under documentaryresearch, interview approach and participant observation. The descriptive analysis is designed to analyze the data. As the villagershave to rely on the creek not only as their main food source but also in other consumer activities, they are poisoned by leadcontamination in the creek. This resulted in both physical and mental illness, especially in children; some children died from suchcontamination, while some became disabled. As for the environmental aspect, the ecosystem is severely damaged. This impact resultedin mitigation measures from various sectors to tackle the issue. However, these mitigation measures were not successful due to lack ofconsistency in operations and follow-up, lack of long-term relief budget plan, failure to understand the villagers’ ways of life, and lack ofintegration and extension of further knowledge and practice. Thus, the measure presented in this research is that of a hybrid betweenthe folkways and modern technology in order that the villagers and responsible organizations will be able to adapt it to achieve theeffective solution of the problem in the future.

Abstract

Diseases related to contaminated drinking water have a greater impact on human health. The purpose of this study ismonitoring the microbiological characteristics of water dissolved in the water distribution system in Tirana. The method used formicrobiological analysis is: membrane filter. This method is based on filtering the water with a vacuum filter equipment using membranefilters with a diameter of 47 – 50 mm, and 0.45 􀈝m pore size. As object of this study have been some areas of Tirana: Kinostudjo,Porcelan, Don Bosko, Kombinati, Laprakë, 21 Dhjetori, Komuna e Parisit, Treni, Ali Demi, Yzberishti, Sharra, ect. The areas are codifyas : (A1, A2, A3, A4, A5,A6, A7, A8, A9, A10, A11, A12, A13, A14, A15, A16, A17, A18, A19, A20 ). Samples for analysis were takenfrom this areas in two stages with difference time a month of each other just to see the difference in microbial load depending ontemperature rise. Monitoring was conducted for indicator organisms (E. Coli, T. Count, Pseudomonas aeruginosa, Enterococcus fecalis).Mainly areas which result in a high contamination are codified as (A3, A4, A14, A17, A20). The reasons for these results are:amortization of distribution system, the lack of restoration of damaged items to the distribution system, illegal interference in thedistribution system, construction of wells in private homes, the use of storage systems and pumping systems for individual supply in anyresidential apartment.

Abstract

This paper discusses the role of urban agriculture with a special focus on community gardens in urban food security andpoverty alleviation in the three high density suburbs of Magwegwe North, Nketa and Nkulumane in Bulawayo metropolitan province ofZimbabwe. Urban agriculture in Zimbabwe is in two forms; one that violates local authority by-laws whereby open pieces of land arehaphazardly cultivated and the form comprising authorised cultivation of urban gardens close to residential areas or on allocated landthough, with limited renewable user rights, by the local authority to farmers. The study focuses on the different beneficiaries, cropsgrown, output and their contributions to the household diet and income. The research is largely qualitative and uses primary datacollected from 15 interviews, 5 focus group discussions and observations on beneficiaries of community gardens in Magwegwe North,Nketa and Nkulumane high density suburbs. The results indicate that community gardens have become a significant source of freshproduce but the shortage of resources inputs, and environmental health risks remain paramount obstacles to realising the full potential ofthese gardens. We conclude that community gardens do increase access and household food security, diversity of diet and contributeimmensely to poverty alleviation among urban households.

Abstract

This paper investigated the interacting effect of the employee’s job competency, extra-role performance and three persistencefactors (current purposes pursuing - CPP), recurrence of unattained purposes - RUP, and long term purposes pursuing - LTPP) on thejob performance of a sample of 200 Romanian employees (participation rate: 86.2%). We used correlation analysis, prediction models,and, as tools, competency assessment checklists developed by means of the Competency Elicitation Interview (Faix et al., 1991),Robertson’s performance scales for job performance (1996, 1997), Smith’s scale for extra-role performance (1983) and a persistencescale (Constantin, 2010). Results support the idea that job performance can be approached from a multidimensional point of view. Thesignificance of extra-role performance and two persistence factors (current purposes pursuing-CPP, and long term purposes pursuing-LTPP) was successfully established, highlighting the important role they have in relationship with job performance, as valid predictors ofsupervisory ratings of employees’ performance. Furthermore, job competencies alone seem to be necessary but not sufficient to predicthigh levels of job performance. Main limitations (such as those who refused to participate they didn’t had comparable demographics withthose who agreed to participate) along with main findings are being discussed.

Abstract

Herzberg’s motivation-hygiene theory is a popular but controversial theory of employee satisfaction. This theory has classifiedfactors that influence employees’ satisfaction into two categories “Motivators and Hygiene factors”. The theory was at the centre of along debate that focused on conceptual and methodological problems. The objective of this comparative study is to understand both thehygiene factors and the motivators in the Libyan environment. The study aims to give a clear picture about the impact of implementingAmerican theories of motivation in different environments. A ratio analysis method has been used in this study; where ratio &gt; 50 percentillustrates positive relation with a theory’s factor, ration &lt; 50 percent indicates inverse relation. The findings support Herzberg Two-Factortheory of work motivation, where all motivators defined by Herzberg were found to be significant satisfiers (motivators) in the Libyanworkplace environments. On the other hand, some differences were found in the hygiene factors; thus these factors have been changedinto motivators due to the differences between the two environments. Furthermore, the study recommends that, to avoid the dominanceof the American theories it is important to develop culturally appropriate theories.
