Abstract:
Plant disease
management should be ecologically based and should be
undertaken within the purview of integrated pest and
diseases management scheme. Therefore, the best method
is to utilize
environment-friendly concept. Really, the use of
bio-fungicide of mainly plant based products has gained
ground in the recent time. Moreover, plant biodiversity
has provided a suitable platform and source of
biologically active materials for use in traditional
crop protection system.
Investigation was carried out to test the efficacy of
aqueous
Ocimum gratissimum
extracts for the control of yam tuber rot caused by
Botryodiplodia theobromae, Aspergillus glaucus,
Aspergillus niger and Aspergillus flavus. Hot and
cold water extracts were obtained from leaves of
O. gratissimum
and were found to be fungicidal against the fungi. The
extracts suppressed the growth of these fungi in culture
and reduced rot development in yam tubers.
The most phytotoxic capacity of hot water extract of
O. gratissimum at 50g/100ml was found against B.
theobromae (95.71%) and A. flavus (96.67%).
Similarly, the most fungicidal values of 95.33% and
79.75% were respectively evoked against A. glaucus
and A. niger by hot water extract of
O. gratissimum at 50g/100ml. The most
mycelial reduction effects of cold water extract of
O. gratissimum at 50g/100ml was against B.
theobromae and A. flavus, evoking
90.48% and100% respectively. Cold water extract of O.
gratissimum at 50g/100ml performed most by
causing inhibition on A. glaucus (100%)
and A. niger (96.40%). The phytotoxic effects of
aqueous extracts of O. gratissimum are without
any known residual implication.

摘要
(Abstract):
广义相对论理论的核心是新的引力场定律和引力场方程.有人说,麦克斯韦在电磁场上做过什么工作,Einstein在引力场也做过什么工作.广义相对论引人注目的特征之一是将牛顿力学中的引力简化为四维时空中的弯曲,“宇宙图景”的新情景不再是“三维空间中一片以太海洋的受迫振动”,而是“四维空间世界线上的一个纽结”.
1914年,Einstein与洛伦兹的学生福寇一起发表了一篇严格遵守广义协变性要求的引力理论的简短论文,发现从绝对运算和广义协变性的要求出发,可以证明诺茨屈劳姆的理论只是Einstein—格罗斯曼理论的一种特殊情况,其标志是真空光速不变这一附加条件;Einstein—格罗斯曼理论包含着光的弯曲,而诺茨屈劳姆的理论没有光的弯曲.

摘要:
利用快子理论发现了新引力公式(16),亚光速物质转动产生离心力这点大家都知道,超光速物质转动产生向心力作用在亚光速物质上产生引力。利用这我们建立了宇宙膨胀理论,参看图2,(22)—(25)。引力子能够转变为静止质量,参看图2,,(24)和(27)。牛顿引力理论是近似的,而爱因斯坦广义相对论是错误的。暗物质,暗能量,引力波,黑洞,量子纠缠和平行宇宙都不存在。

Abstract:
For strategic decision
making in each country and its organizations the future
should be considered and determine the position of the
country and it's organizations in future, and plan to
achieve that position. Therefore, no future planning is
possible without prediction, so in technology strategic
planning technological parameters that affect the future
of the organization should be defined by fore sighting
and forecasting technology and uses this parameter for
long term planning. This article explains this topic and
focuses on technology prediction and futurism that are
the guideline keys for strategic planning and gives
brief information about two countries that were pioneer
in this field (Japan and Turkey).

Abstract:
America by importing
about 10 million oil barrels per day is very dependent
on Middle East as a region with about 56.6% of the oil
in the world. This dependence on Middle East oil
encountered USA with an extensive political and security
issues during the previous decades. Here Barak Obama
administration in its strategy emphasized more on some
policies such as “Diversification”, “reserve of fuel
resources”, increasing “energy efficiency” and investing
on new energies to reduce USA dependency on Middle East
oil by decreasing oil consumption.

Using Series Active
Filter for Limitation of Fault Currents

Yaser.hoseynpoor@gmail.com
Abstract:
Power quality improvement
has become a very important topic in power systems over
the past several decades. Custom power devices (DFACT)
are a kind of Flexible AC Transmission Systems (FACTS)
devices which are used for power quality enhancement in
distribution networks. The Series Active Filter or
dynamic voltage restorer (DVR) is a modern custom power
device used in power distribution networks to protect
consumers from sudden sags (and swells) in grid voltage.
Implemented at medium voltage level, the DVR can be used
to protect a group of medium voltage or low voltage
consumers. However, the DVR will therefore be tasked to
mitigate even more faults involving downstream loads.
Large fault currents would flow through the DVR during a
downstream fault before the opening of a circuit
breaker. This will cause the voltage at point of common
coupling (PCC) to drop, which would affect the loads on
the other parallel feeders connected to PCC.
Here, the Z-source inverter based DVR is proposed to
compensate voltage disturbance at the PCC and to reduce
the fault current in downstream of DVR. By calculating
instantaneous current magnitude in synchronous frame,
control system recognizes if the fault exists or not,
and determines whether DVR should compensate voltage
disturbance or try to reduce the fault current. The
proposed system is simulated under voltage sag and swell
and short circuit conditions. The simulation results
show that the system operates correctly under voltage
sag and short circuit conditions.

Abstract:
There are many tests available
to help you and your students discover your best
learning style. Generally speaking, however, if you are
someone who is more likely to think in pictures, prefer
to meet with someone in person, and are more likely to
want visual diagrams when completing a project you have
tendencies towards visual learning. Similarly, if you
are more likely to think in terms of sounds, prefer to
speak on the phone with someone, and want verbal
instructions then you tend towards auditory learning.
Finally, if you are more likely to think in terms of
moving images like mini-movies in your mind, prefer to
participate in an activity when you meet to speak with
someone, and tend to jump right into a project without
reading directions you tend towards tactile/kinesthetic
learning.

Abstract:
An experiment in the split plot design in the format of
completely randomized blocks with four replicates was
carried out in the city of Firuzkooh to study the effect
of seeding date on safflower cultivars in the years
2009-2010. The experimental treatments included the
seeding date as the major factor (four different dates
20 days apart from each other – February 28, March 20,
April 9, and April 29 ) and the cultivar as the minor
factor( the three cultivars of Sina, Isfahan 14, and
Padideh). Results obtained show that yield and its
components are significantly affected by delays in the
seeding date –that is, the more the seeding date is
delayed from the suitable seeding date, the more the
yield is reduced. Safflower cultivars also show
statistically significant differences due to their high
production potential and also because of the degree of
their adaptation to the weather in the area. As a whole,
the cultivars can be seeded in Firuzkooh at the seeding
dates of February 28 and March 29; and these two dates
did not give significantly different results. Based on
the results of this experiment, the cultivar Padideh was
superior in many of the traits investigated, while the
cultivar Isfahan 14 did not meet the necessary
requirements to be recommended for Firuzkooh.

Principles for the Teachers of
Adults and its importance

E-mail:

Abstract:
For most adults,
being out of the classroom for even a few years can make
going back to school intimidating. If they haven’t taken
a class in decades, it’s understandable that they would
have some degree of apprehension about what it will be
like and how well they’ll do. It can be tough to be a
rookie when you’ve been an expert in your field for
many, many years. Nobody enjoys feeling foolish. Your
job as a teacher of adult students includes being
positive and encouraging. Patience helps too. Give your
older students time to respond when you ask a question.
They may need a few moments to consider their answer.
Recognize the contributions they make, even when small.
Give them words of encouragement whenever the
opportunity arises. Most adults will rise to your
expectations if you’re clear about them. A word of
caution here. Being positive and encouraging is not the
same as being condescending. Always remember that your
students are adults. Speaking to them in the tone of
voice you might use with a child is offensive, and the
damage can be very difficult to overcome. Genuine
encouragement from one person to another, regardless of
age, is a wonderful point of human interaction.

Joint operation of
several types of Power Plants to Increasing Net Profit
in Deregulated Power Market

Abstract:
This work proposes joint
operation of power plant and electric energy storage
plant in order to maximizing overall profit in a
restructured electricity market. Among electric energy
storage technologies, we select NaS battery systems for
coupling with power plant because of their enough
technological maturation and less environmental impacts.
The goal is investigating the coupling efficiency on
profit increment considering various intensities of
power plant’s fuel constraint. In order to reach this
goal, the amount of overall profits of fuel-constrained
power plant, NaS battery plant and their coupling are
first calculated in a specific time interval. Then, the
coupling efficiency is determined using incremental
profit rate. Having an appropriate strategy to calculate
this parameter is essential. Hence, a comprehensive
approach to self-schedule of individual and coupled
plants is developed. This comprehensive self-scheduling
approach is therefore formulated and solved as a mixed
integer non-linear programming (MINLP) problem.
Numerical results for a case study are discussed.
