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. The test results of compressive strength after 14 days with the lowest value at 3% of additional material combination of fiber content of 6% fiber stem and fruit by 70,384Kg/cm²with a water content of 15,254% In weight position 2,935Kg as well as the highest value on the combination of additional material 0% rods fiber content and 3% fruit fiber by 98,821Kg/cm² with a water content of 15,031% In weight position 3,058Kg. While N (without additional material) with a compressive strength below the average id 63,704Kg/cm2 with water content of 10,167 in weight position 3,072Kg.

Abstract

This paper harped on human capital development in science, technology and mathematics education withspecial reference to its implications for sustainable development in Africa. The usefulness and relevance ofscience, technology and mathematics education to sustainable development in African Nations are nolonger in doubt. Therefore any nation that plays with these indices plays with her own development.America is a super power today because she has been able to transfer her science into technology. Thiscould also be done in Africa through effective and efficient development of STM human capital. This paperdiscussed the rational for human capital development in STM education, the economic implications ofhuman capital development in STM education and the attendant suggestions to improve human capitaldevelopment in the STM programme in Africa.

Abstract

Concentrations of some heavy metals in crops such as banana, pawpaw, maize, sugarcane and mangoirrigated with water from Makera drain, Kaduna-Nigeria were investigated. These were determined byAtomic Absorption Spectrophotometer (AAS) technique. The metals were found to be in the magnitude ofZn&gt; Pb&gt; Cr &gt;Cu, while that of the trace metals are Mg&gt;Na&gt;Ca in decreasing order of magnitude. Therewas varying level of significance (p&lt;0.05) with increased concentrations of the determined metals. The highlead and chromium concentration (above WHO limit) in the irrigated crops may lead to its toxic effects asit can bio-accumulate in the tissues and muscles of human and domestic animals that utilize them as feed.It is thus observed that the water from the Makera drain used to irrigate crops may have delibetating effecton the consumers. Consumption of crops irrigated along the drain should be discouraged as it mightcontain high concentration of chromium and other toxic substances.

Abstract

Curcuma longa is the botanical name of a ginger plant belonging to the family of zingiberaceae. Itcontains a colourful condiment with a distinctive pungent flavour. The natural product (curcuma longa)has a pH range of 8 to 9. The quantitative evaluation gave a percentage yield of 15.2. On Thin-layerchromatographic analysis, the dye gave Rf(methanol) value as 0.83. The ultra-violet visible (UV) spectra ofthe dye also showed absorption of 480nm corresponding to the region of dyes. Infra-red (IR) spectra of thedye from methanol extract showed intense peaks at 3423.8, 2961.7, 1739.5 and 1380.9 corresponding toO-H stretching of alcohol, C-H stretching of methyl and methylene groups, C=O of amides stretching andC-H bending vibrations of methyl and methylene groups respectively. An extraction was conducted wherea colourful yellow dye was produced from powdery curcuma longa with methanol as solvent. The indicatorproperty of the extracted dye was investigated using methyl orange as a reference indicator. It wasobserved that the titrimetric end-points obtained for the dye present in curcuma longa comparedreasonably with those of methyl orange. I strongly recommend that the dye from curcuma longa can beused as alternative to methyl orange during titrimetric analysis.

Abstract

The purpose of this study is to explore the challenges of the existing research on learners’communication behaviors in theEnglish-as-a-foreign-language (EFL), mainly Asian context, and identify the fields which need to be further explored. Byreviewing the research investigating factors influencing EFL learners’ willingness to communicate, this paper argues thatthough learners’ use of English in communication has become the common interest in EFL education research and factorsinfluencing their oral participation have been widely documented, there are limitations.This paper suggests that it is necessaryto conceptualize the communication behaviors of EFL learners in English in terms of situational-specific practices, and toidentify the underlying causes of student self-exclusion from oral tasks, by examining the context in which these students arelocated. In light of the review of the literature, this paper also identifies some variables which need to be taken intoconsideration in future research, such as identity negotiation, investment in English learning, international posture andimagined community.It is hoped that this paper will inform the development of L2 communication research.

Abstract

Nowadays, one of the ways to reject a woman in Africa especially Nigeria is when the spouse elopes with a lady in theWestern state in the guise of seeking greener pastures. Economic depression, lack of job and general insecurity, politicalinstability and lack of social amenities have been attributed to reasons many men leave their home country for the Westernworld for better living for self and the family; but the current trend has been abandon, neglect and eventual divorce of thewomen with their children. This has brought shame and guilt to many women because of the perception of many Africanstowards divorce. This empirical study involved twenty-five women whose husbands have been overseas in the last five to tenyears and waiting to be invited over; but were later divorced. It was established that these women were suffering from guilt andshame. The twenty-five volunteer women were subjected to twelve weeks counseling using self-developed scales that werepatterned after Cognitive-Attribution Therapy of Lewis (1993), and Shame and Guilt of Barrett (1995). The prognosis revealedthat the level of shame and guilt of the women were reduced; some of them concluded to move forward by remarrying, whileothers concluded to take the incidence as fate and continue to take care of self and children. It was concluded that manypeople inflict self pain on self for not being responsible for a particular occurrence, but psychological therapies such asCognitive-Attribution can be applied to help such individuals.

Abstract

Social Media, the new term that has invaded our daily lives in high velocity, consists of social networking, playing interactivegames, making international friendships and communicating, in general, worldwide. On the other hand, Human Resources areoccupied with terms such as recruitment, career advancement, motivation, employability, evaluation. Those two seem sodifferent and diverse but nowadays a correlation and a parallel walk is occurring. Social Media sites such as Facebook,Linkedin, Twitter etc are currently being utilised as a company promotion tool under their will to reach in a personal way each'user' or as a possible employability entrance, and, in same recent cases, reason for dismissal. But how these two actuallycombine or better correlate? This latter in addition, firstly, to the way this relation is widely perceived by potential and currentemployees as well as companies' Human Resources departments and secondly, the emergence and application of all these inthe case of Greece, will be the research scope of this paper presenting the traditional way of recruitment and selection as wellas career advancement and evaluation through the basic principles of Human Resources Theory and practical experience, incorrelation with the will to explore and investigate the opportunity or not to utilise social media as an additional tool in order toadvance in a modern world of Human Resources.

Abstract

The European Union has offered autonomous trade concessions to the Balkan countries. All industrial products and mostagricultural products have duty and quota free access. “Autonomous” means that the European Union immediately opens theinternal market, while a longer period of transition is conceded to the Balkan countries before opening up their markets to EUcompetition. Albanian economic performances have improved recently. But encouraging signs of economic development arebeing at risk by various uncertainties and deficiencies in the Albanian development system. Electricity shortage is a majorhandicap of the country. Many working hours are getting lost when electricity is switched of. This increases costs of productionand business management. Infrastructure - traffic and transportation - is a problem, which particularly impedes economicdevelopment and investment in the more remote and rural regions. Regional development is considered a high priorityobjective by most experts. There has been moderate progress in judicial reform, which is a key priority of the Opinion. Thisarticle presents a summary of the influences of technical assistance and administrative capacity in development of Albaniangovernment. In the centre of this study we are using the concepts and innovations of the E-Learning, which is gainingsignificant interest in distance education, including reforming political, social and economical developing in Albaniangovernment reforms and other details.
