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.

Abstract

Our concern is lecture is basically an evaluation of the National 10 – year Development Plan onEducational Reforms and The part of NEEDS policy on the making of Millennium Development Goals.MDGs in 2005. The Policy provisions were critically evaluated as to what extent they have gone midwayinto the Targeted year 2015. It was found that by year 2010, the implementers of these 10 – years –Development plan have not gone near 45% of what should be 100% by 2015. The UBE and MDGs goalsmay end up as mere pipe dreams and a drain on the national resources if double Efforts are not made nowto strengthen the resolve to achieve these set goals. It was recommended that all the policy options in allthe section of our educational system must be vigorously pursued in order to attain these goals we have setfor our nation Nigeria

Abstract

Women are marginalized in the human society from the day of its origin in all parts of the world. Like anyother region of the world, south Asia is not a region, with this major problem. This paper is an attempt tomake a comparative analysis on Women empowerment in seven South Asian countries. Since internationalcomparison provides us a better comparison of status, ranking is compared mainly. This comparison can bedone effectively by comparing few indices like Gender Related Development index, Gender empowermentmeasure, Gender inequality in Education, Gender Inequality in Economic activity, Political EmpowermentMeasure etc. This paper is a small piece of a major research done over this area. This paper has comparedonly the comparative women empowerment indicators like Gender Related Development index and Genderempowerment measure for a point of time and found that women are not in equal status throught thisSouth Asian Region. Again Gender Development index ranking and Human Development Ranking aloneare compared over a period of time ie. from 1994 to 2011. The overall analysis has brought a conclusionthat South Asia is a region that need special attention from the world and international agencies for itsgender empowerment and human development as they are ranked beyond 134th Rank in HumanDevelopment Index and are placed beyond 98th rank in case of Gender Development Index except in caseof Sri lanka and Maldives where there are continuous crisis.

Abstract

Study was conducted at the Microbiology laboratory of Lagos State Polytechnic, Ikorodu to determinequality deterioration of tomatoes sample using plastic, carton and basket storage method for period of 7and 14 days respectively. 1000g matured tomatoes sample were taken from a farm settlement atOdogunyan-Ikorodu, Lagos to determine the physiochemical properties; moisture content (MC), protein (P),fat (FT), fibre (FB), ash (A) and vitamin ‘C’ (VC) of the produce before and after storage, also, microbialcount and pathogenic presence after 24 and 48 hours of storage. Result obtained showed 95.00%MC,2.21%P, 0.30%FT, 0.81%FB, 2.34%A and 67.50mgVC before storage. Tomatoes stored in the carton had thehighest nutritional values in terms of quality; 55.48%MC, 0.85%P, 0.18%FT, 0.58%FB, 1.00%A and2.50mgVC after 14 days. Penicillium, green fungi which grows in ripening fruit was found in the plasticafter 48 hours with about 2.89 * 106 colony count while, sample stored in the carton were more susceptibleto less colony count (1.52 * 106) of fungi after 48 hours. The carton gave better results when compared tobasket and plastic methods of storage in the study area as far as these quality attributes assessed areconcerned.

Abstract

Over 80% of graduates in Nigeria are unemployed, in spite of their qualifications, they are employable yetthey are not employed. The inability of the higher educational institutions to meet the needs of thesegraduates as well as promotion of economic self reliance and self sufficiency has resulted into youthsjoblessness (unemployment). These have added to increase in restiveness among Nigerian youths. Thisresearch is therefore undergone to investigate the relationship between entrepreneurship and employabilityamong Nigerian graduates. The paper, discussed the concept of entrepreneurship and employability. Sinceemployability is the act of having qualification that enables someone to employ you, the research alsolooked at the basic skills that can make one employable and at the same time becoming self reliant. Alsodiscussed are ways forward in promoting entrepreneurship among Nigerian youths and how teaching ofcreativity and problem solving skills can help reposition Nigerian graduates.

Abstract

This document aims to analyze the genealogy of the concept of cultural heritage from the Middle Ages tothe twenty-first century, to establish the reason why it is still necessary to review and reconceptualize theway to understand the cultural heritage, where the material and immaterial aspects mutually interactaccording to its socio-cultural functions. The impacts of the market economy over the cultural heritagedefinition and management after the second part of the twentieth century make evident why culturalheritage preservation has to be redirected and redefined. It has to involve not only the communities’perspective and interests, but also different cultural heritage dynamics and understandings out theEurocentric perspective that still rules heritage issues.

Abstract

The environment is changing very fast, it is reshaping at a rapid pace specifically because the emergence ofnew technologies is changing the society, changing the way we live, the way we communicate and dobusiness and also the way we learn. Consequently, our educational systems are facing significant pressureto change the way we educate our children too in order to adequately prepare them to live, learn, andwork in a global, digital age. Education is all about change and creativity, therefore there should becreative models for engagement in learning in a shifting educational landscape. Education in the 21stcentury is different from what it used to be in the 17th or 18th century because of the changes overtimeand subsequently the variations in the learners’ needs particularly in this world of technologicaladvancement. Teaching and learning process should be more effective by constant renewal in theknowledge impacted and shared with the students all the time. The mode of instruction delivery needs tochange from traditional teacher-centred to new learning that is learner-centred and globally acceptable asis the case with the USA and other countries where education is undergoing a major paradigm shift(change) from traditional learning environments focused on the teacher as the “deliverer” of knowledge tonew open learning environments focused on the learner as information seeker. Although the movement inthe USA and other developed countries took root first at the primary and secondary levels of education, ithas had an impact on tertiary education as well. Likewise, there should be turn of the tide in the NigerianEducational System.

Abstract

Globalization presents contradictions, leading to its manifestation as good and bad – a double edgedsword. For the proponents of globalization, it is a unifying force, an economic process that offers people avariety of choices, leading to an improved quality of life. One can also argue that globalization is goodgiven the example of China and Indian where most people have moved from abject poverty. However, thenegative aspect of globalization has resulted in a tremendous income inequality in most developingnations. There is a high rate of unemployment in these countries as both skilled and unskilled youths havebecome increasingly marginalized and disfranchised from the promise of “development.” The position ofthis paper is that, the processes of globalization in the last few decades have continuously restrictedpeople’s lives, widened the gap between the rich and poor, north and south, resulting in a fragmentedglobality. And for the particular case of the Niger Delta region, economic globalization has resulted in thedisenfranchisement of the youths. The discussions of this socio-economic phenomenon in this paper will bebased on the field work that commenced in 2004 to 2010 in Obagi, Obelle, Omoku, Ogbogu, and Obitecommunities

Abstract

This paper analyses the impact of climate change on Nigeria’s cereal grain yields, variance and covariance.Maize and rice were selected based on their distinct production in almost all the States in Nigeria. A paneldata stochastic production model with heteroscedasticity was employed in analysing the data. The dataconsists of a panel of eight States and 18 time periods. The eight states spans across the six geopoliticalzones. The cereal grains considered are rice and maize. The simulation results show that there would be anincrease in rice yield whereas its variance would increase. The contrary holds for maize. The covariance ofthe two crops would reduce in future due to climate change. The results have implications for allocations ofagricultural land among crops, for crop production mix, and for adaptation and mitigation policies.
