Abstract:
This study
aimed at assessing Shea nut processing among rural households in
Fakai Local Government Area of Kebbi State, Nigeria.
Proportionate random sampling technique was used to select one
hundred and two (102) Shea nut processors. Primary data were
collected with aid of interview schedule and data analysis was
carried out using descriptive statistics. Result revealed that
91.2% of Shea nut processors are mainly females, 49% aged 51 and
above years, 73.5% of the processors are married, while 37.3%
had no formal education. About 35.3% of the processors are
farmers, while majority (60.8%) of the processors had between 16
– 20 years’ experience in Shea nut processing. However, the
processing techniques are manual, time consuming, and highly
demanding. There are limited market opportunities for the
product. Besides, inadequate credit facilities, processing
drudgery and inadequate storage facilities were the most severe
constraints of the processors. It could be concluded that
processing
techniques are manual, time consuming, and highly demanding.
There are limited market opportunities for the product. It is
recommended that Federal Government should curb importation of
products of Shea nut/butter origin to stimulate the
establishment local industries that will use Shea nut/butter as
raw materials. This will lead to mechanisation and
commercialisation of the sub-sector. Extension should help
locate Shea butter markets and motivate processors to meet
specifications.

Abstract:
This scientific
research article focus that “HUMAN ANCESTOR” shall be
considered as “TERRORIST” evolved from “Dark Cloud of
Stardust”. The human Ancestor shall be considered as lived
in “MARS PLANET” in the early Universe under “Perfect
law and order” (kingdom Rule, absolute ideology) under the
influence of “Zero hour radiation” environment also
called as “J-RADIATION”. It is speculated that the
stardust cloud (as stipulated in Big-bang theory) shall be
considered as composed of three-in-one ions of Anti-photon,
Anti-Electron, Anti-Proton. The supernatural star dust shall
also be considered as having “Terrorist Behavior” in the
early Universe. It is further speculated that in the “expanding
universe” the environmental condition of universe consider
consistently changed into three distinguished behavior in
three Nuclear ages as described below.
i.
Terrorism environment
ii.
Revolutionism environment
iii.
Evolutionism environment.
During the course of time the “Mars
populations” do not want to live under “Strict law and
order” considered descended to “EARTH PLANET” for
more freedom and become “Revolutionist”, “Evolutionist”
thereafter. The concept of various Ethnicism, Racism, shall be
considered as developed on the Earth Planet subsequently.
“Expanding Universe shall
mean consistent variation in environment condition with respect
to varied relative position of SUN, EARTH, MOON and
varied angle of its rotation on their axis”.

Study the Educational-
Cultural Rights of Religious Minorities in Education System of
Islamic Republic of Iran
Mehrnaz Zemami Amlashi1
*, Zahra Pishgahpour 2, Fateme Jafarinia3
Abstract:
Education in Iran; From the
viewpoint of the constitution of the Islamic Republic of Iran,
freedom of education is considered as an acceptable
pre-assumption. In fact, the purpose of the legislators of the
constitution was to eradicate illiteracy in the country and to
improve public knowledge of people considerably. At the same
time, this document has paid particular attention to the
principle of education and emphasizes on providing public and
free education not only in elementary school, but also to the
secondary school; thus, one of the basic duties of the
government, in view of clause three of principle three of the
constitution, freedom in education and physical education should
be provided for all in all levels and the government should
facilitate and popularize higher education. Employing the phrase
“for all” in clause three of principle three, and “for the
entire nation” in thirtieth principle directs minds to the
subject that constitution believes in the right of education for
all nationals of the company, and does not accept discrimination
among the subjects of the country; although, individuals; too,
benefit from this advantage as per their talents and merits in
various degrees. Therefore; based on this argument, some jurists
have stated: “There is no legal restriction in education in
terms of age, gender, ideology, beliefs or religious and
spiritual beliefs”.

Abstract:
1871年刚刚打造成形的德国,想跟英美竞争照明工业优势,几十年间德国一批顶尖物理学家百般努力,都不能解决黑体问题。直到1900年偶然中出现的普朗克,才得以完成。这个高昂的代价,即使后来德国政治几经曲折,换来的是整个民族智慧站到了“量子”高地时代。在真实世界这个难以捉摸的量子概念,发展出的量子力学,如量子遂道扫描显微镜,是一种比电子显微镜放大倍数更大的显微镜,对研究基因组学十分有用。还有激光、核磁共振、核元素分析等常见的应用,对人类学考古也十分有用,已成人类上古史大统一考古用的主流方法。邓小平同志说:“过去也好,今天也好,将来也好,中国必须发展自己的高科技,在世界高科技领域占有一席之地。这些东西反映一个民族的能力,也是一个民族、一个国家兴旺发达的标志。”

Summary:
High performance
liquid chromatography is now one of the most powerful tools in
analytical chemistry. It has the ability to separate, identify,
and quantitate the compounds that are present in any sample that
can be dissolved in a liquid. Today, compounds in trace
concentrations as low as
parts per trillion [ppt] may easily be identified.
HPLC can be, and has been, applied to just about any sample,
such as pharmaceuticals, food, nutraceuticals, cosmetics,
environmental matrices, forensic samples, and industrial
chemicals. Nowadays, GLPs
are solid standards for government registration and regulatory
research facilities. Outside the U.S., OECD GLP is more familiar
and has been applied in some other countries [1-2]. It is
important that not only proper science must be used in the
scientific research but also quality assurance systems should be
implemented while we attempt to produce reliable and
reproducible data in regulatory research because all of these
activities have great impacts on toxicology and the environment.
This article discussed the Good Laboratory practices for High
performance Liquid Chromatography for precise results and long
life of the instruments and its consumable accessories.

Abstract:
Policy makers and service providers have increasingly come to
view information and communication technologies (ICT), and
particularly the Internet, as an important tool in providing
disadvantaged groups and areas with access to information,
services and markets that would otherwise be inaccessible. The
concept of development of the rural, today, is not just project
initiatives and governance; it is much more beyond that. This
paper uncovers a whole plethora of ICT emergence as a technology
of the new millennium. Against the backdrop of the ongoing ICT
boom, this paper makes an attempt towards studying its
applications and usage planning process and policy making for
the rural communities focusing on how it helps in aligning the
key factors and reduce the problems of alienation, fragmentation
and dislocation of knowledge.

Micro-credit and its effect on agricultural development
Mina Abarashi

University, Damavand, Iran
*Email:
sharif11070@yahoo.com
Abstract:
The major beneficiaries of micro-credit programs are rural women
and low-income groups who use the micro-credits to improve their
social and economic status. For the past two decades,
micro-credit has been one of the solutions considered in order
to expedite investment process and strengthen the financial
bases in rural and deprived areas. Empowerment and poverty
eradication in deprived communities through improving
productivity are all results of micro-credit. Micro-credit has
proven its value in development as an effective tool in
struggling poverty and hunger. It has the ability to change and
improve people’s lives, especially people in need. In
micro-credit programs there are some other parts like small
saving accounts and deposits; that’s why they are presented as a
credit-saving program . The two terms in “micro-credit” refer to
tow fundamental concepts that it is dealing with. The first term
“micro” refers to inefficiency of classical economists’
development methods. Focus on the term “micro” implies revising
the market’s economical recommendation in rural development.
Small and micro-scale activities are the ones done within the
local markets with goal of providing livelihood for households
and with least link to the national and international economy.
The second term “credit” refers to rural circumstances and lack
of official sources which is a critical problem for them. By
designing a micro-credit plan, the system is trying to provide
credit sources for poor families and increase efficiency of
rural market. In micro-credit system, production is mostly local
and industrial, therefore economic surplus in these programs is
relatively law.

Abstract:
Aerobic biodegradation of synthetic Paraffins and Olefins in the
Gulf of Guinea sediments were monitored over a 120 day period in
an indoor benthic chamber basin tests measuring 18 x 30 inches.
At each 30 day interval, residual hydrocarbons were measured
with gas chromatograph while microbial populations were
quantified with the most probable plate number method (MPN). At
the end of the 120 day monitoring period, the following %
degradation rates were recorded for different hydrocarbon
substrates; Linear Olefin (90%), Synthetic Paraffin (82%), and
Internal Olefin (86%). The overall degradation sequence showed
that the Olefins degraded faster than the Paraffins but both
hydrocarbon substrates were readily biodegradable by the
indigenous microbial flora of the Gulf of Guinea sediments. This
study demonstrated that over 85% of the degradation of Synthetic
Paraffins and Olefins on the surface of sediments were carried
out by aerobic microorganisms.

Abstract:
Today, education and training
discussion is a reality of modern days. Living in such modern
world may be impossible without education and training and
without possessing a training system. On the other hand, there
is essentially no discussion about education and training
principle; but the important is interactions for how and what
education, i.e. all thought and training schools focus on how
and what education and training provided. All attempts of Master
Motahari focused on how interiorize the education and training
of Islam’s point of view. Explaining the objective of education
and training of Islam’s point of view, analyzing the principles
of training and education, recognizing the factors influencing
on education and training are the main objectives of this study.
Above all describing the properties of Islamic education and
training. is another point that will be explain in this paper.

Abstract:
The karyotypic and cytological characteristics of Rosy barb,
Puntius conchonius (Hamilton, 1822) (cyprinidae) were
investigated by examining metaphase chromosomes spreads from the
anterior kidney following Thorgaard and Disney (1990). The
fishes were obtained from the local fishermen and transported
live to the Limnology and Fisheries Laboratory of Centre of
Research for Development, University of Kashmir. Ten fish were
injected intraperitoneally with two doses of phytohemagglutinin
(PHA), 4µg g-1body weight with a 20-h interval to
induce cell division. After 8 h in 20˚C water, the fish were
injected intraperitoneally with colchicine 0.05% @ 0.5ml/50g
body weight to depress the cell division in the metaphase stage
and left for 2-3 h before sacrificing. Kidney and gill epithelia
were used for karyotype analysis. The diploid chromosome number
of the fish was 2n=50, consisting of 11 pairs of metacentric, 8
pairs of submetacentric and 6 pairs of telocentric chromosomes
respectively. Centromeric index, arm ratio and Fundamental
Number were determined as 0-50, 1-∞ and 88 respectively.
No heteromorphic sex chromosomes were cytologically detected.

Abstract:
by looking at women’s history of economic and social life, we
can find that this great group, continuously have played basic
role in forming economic condition of country. This great group
consistent with men have had active role at areas of
social-economic activities and always have had major part on
economic production of society. Nowadays, supporting family
supervisor women is adopted by universal society, as politic,
economic a social concern and nearly all countries applied
related approaches, and however these efforts have resulted in
failure, in so many cases. paying part of cost of life by
government or charities, establishing forums to analyze family
supervisor women’s problems, supplying necessary facilities to
grow and improve child’s life quality and paying facilities to
provide sustainable employment, are among most important
approaches to support family supervisor women. Paying credit
facilities to access sustainable employment with easy terms at
limited time, is one of the most important approaches to support
family supervisor women. Because alongside supplying their
continues needs, their esteem wouldn’t be marred. Currently,
this approach is used at many countries and positive results
have emerged.

Abstract:
Concept of adult education
in revolutionary countries, is a combination of these two
concepts. Changes in these countries due to social, political
and cultural revolution, resulting from, literacy and continuing
education necessary to find because of the revolution, there is
cultural poverty on the other hand the implementation of
development plans and the need for skilled personnel are expert.
General adult education system based on economic conditions -
social and cultural community is different and each specific
goals will follow. General objectives of adult education and
literacy in two categories is divided into professional
education.
It’s your job to listen carefully for teaching
moments and take advantage of them. When a student says or does
something that triggers a topic on your agenda, be flexible and
teach it right then. If that would wreak havoc on your schedule,
which is often the case, teach a bit about it rather than saying
flat out that they’ll have to wait until later in the program.
By then, you may have lost their interest.

Abstract:
The main objective of this study was to identify the problems
associated with financing community development projects in
Obowo Area of Imo state. The specific objectives were to:
determine the sources of financing community development
projects, identify the commonest projects initiated and executed
in the community, describe the roles of these source In
financing community development projects, examine the problems
of financing community development projects, and to make policy
recommendations based on the findings. One hundred and twenty
{120} respondents were randomly selected from ten (10)
autonomous communities in Obowo Area of Imo state. Data were
obtained using structured questionnaire. Simple statistical
tools such as frequency, percentages, and tables, were used in
data analysis. Result also shows that the self-help group is the
most available source (99.1%) than other sources. The major
problems encountered during financing the projects include:
Embezzlement of funds, mismanagement of funds, available sources
not co-operating, lack of security at the project site, and land
– owners demanding much money for compensation. The solutions
proffered include: proper management of funds, payment of taxes
and rates, creation of more autonomous communities, among
others.

划分物理学和力学的界限也就把场方程和运动方程加以区分.或许正如前面所指出的那样,既然忽略了离散存在质点和场的相互作用,所以场方程和运动方程都是线性的.在用抽象的理论认证某个质点的时候在力学上就把这个质点看成是一种纯属被动的实体,而力也就施加在它上面,同时又和这个质点本身无关,这也正是解决力学问题的前提.在场论中力场被相应地看成所谓被动的一面,看成是不依赖于场的粒子(即场源)的函数.根据力来确定运动,根据力与坐标的关系确定力是牛顿在《自然哲学的数学原理》中所提出的两个问题.在解决第一个问题时,牛顿依据的是他所阐明的运动公理.同时在《原理》中还解决了另一个问题,确定了把力(引力)和坐标联系起来的函数的形式.如所周知,这是古典物理学的出发点.以后物理学的其他部门就是按牛顿的引力场的式样构成的.
在物理学发展的影响下,当力学把标量也包括到自己的基本概念之中的时候,已知力和初始条件就能决定质点位置的牛顿运动方程将要被另一种方程所取代.
