How to
Derive The Fine-structure Constant--1/α
= Fn/Fe =
hC/(2πe2)
From Author’s New
Black-hole Theory and Formulas?

【Abstract】。What
is the fine-structure constant--1/α
= hC/(2πe2)
= 137.036 ? It has been an important problem not recognized and
unsolved
by scientists for more 50 years.
A Chinese old famous saying: The stones of other hills may be
good for making jades.Applying the hydrogen atom as a model and
contrast, a proper ratio Fe/Fg between
the electrical force Fe and the
gravitational force Fg could be really
established as a famous Dirac large number Ln = Fe/Fg
≈ 1039,
because in a hydrogen atom, either the electron or the proton
can be acted by the electrical force Fe and the
gravitational force Fg together;in
addition, Fn and Fe have the same
acting distance R. Right now, physicists have not found the
correct formula or numerical value of nuclear strong force—Fn.
Drawing the same mathematical and physical analogy from Ln
= Fe/Fg, a special mini black hole of Mbo
= 0.71´1014g
can be a better choice as a model, in which each one of all
quarks decomposed from protons must be acted by the electrical
force Fe and the nuclear strong force Fn
together. Thus, the proper ratio Fn/Fe
between Fn and Fe can be correctly
established and proved that, Fn/Fe should
just be the fine-structure constant, and Fn/Fe
= 1/α
=
hC/(2πe2)
= 137.036.Richard Feynman once said some words about the fine-structure constant:
[It has been a mystery ever since it was discovered more than
fifty years ago, and all good theoretical physicists put this
number up on their wall and worry about it... It's one of
the greatest damn mysteries of physics: a magic number that
comes to us with no understanding by man. You might say the
"hand of God" wrote that number, and “we don't know how He
pushed his pencil.”]

Abstract:
Objective:
The aim of the current work is to
study the outcomes of hysteroscopic myomectomy at Early Cancer
Detection Unit at Ain Shams University Maternity Hospital over a
12-year period between 1996 and 2007. Patients and Methods:
The current study is a retrospective analysis of outcomes of
hysteroscopic myomectomy procedures performed at Early Cancer
Detection Unit at Ain Shams University Maternity Hospital over a
12-year period between 1996 and 2007. Data were retrieved from
patients’ case records available at the Early Cancer Detection
Unit. Operative procedure details and notes were obtained from
patients’ case records. Patients were contacted directly,
through mail and/or phone calls to complete follow-up data,
procedure outcomes as well as missing data. Results: A
total of 78 women, who underwent hysteroscopic myomectomy during
the period between 1996 and 2007, were included in the study. Of
the included 78 women, 34 (43.59%) had menorrhagia, 34 (43.59%)
had primary infertility, 8 (10.26%) had secondary infertility, 1
(1.28%) had recurrent miscarriage and 1 (1.28%) had amenorrhea.
Uterine perforation occurred in 2 (2.57%) cases; both were
managed conservatively, with no need for exploration. Cervical
lacerations occurred in 2 (2.57%) cases. Excessive bleeding (>
500 ml estimated blood loss) occurred in 1 (1.28%) case. Of the
included 78 women, only 25 (32.05%) were accessible for
follow-up. Of the accessible 25 women, 10 (40%) had
hysteroscopic myomectomy performed for menorrhagia. Of the 10
women who had menorrhagia, 9 (90%) had it resolved. Of the
accessible 25 women, 15 (60%) had hysteroscopic myomectomy
performed for infertility; of them 7 (46.67%) women got
pregnant, while 8 (53.33%) remained infertile. Of the 7 women
who got pregnant, 2 had term delivery, 2 had preterm delivery,
while 3 had first trimester spontaneous abortion. Conclusion:
In conclusion, hysteroscopic myomectomy for either abnormal
uterine bleeding or infertility seems to have promising success
rates with much low complications rates, and should be offered
to all women who have the diagnosis of symptomatic submucous
myoma and choose to preserve their fertility as the first line
of surgical treatment.

Abstract:
In this paper we have discussed
about the working of three phase high voltage direct current in
many fields. The derivation of High voltage TL converter is
extended to all DC-to-DC converters, and families of TL
converters are proposed in this paper. And High voltage Direct
Current allows to power transmission between AC System by
distribution systems, and it can increase system stability by
preventing cascading failures due to phase instability from
propagating from one part of a wider power transmission grid to
another. And high-voltage direct current electric power
transmission system used in direct current for the bulk
transmission of power supply, and here we show the all areas
where we used the power transmission of common alternating
current systems.

ABSTRACT:
Irish potato (I.P) (Solanum
tuberosum L.) tuber is a nutritious but highly perishable
crop that is subject to high fungal spoilage and wastage due to
non-availability of appropriate storage techniques. Therefore,
the present work was carried out to isolate and characterize
fungal agents of spoilage of I.P and to determine the
effectiveness of traditional methods of preserving the I.P. 460
I.Ps were randomly bought from 5 markets in Lagos and
stored in 50, in each ampoule under 6 storage conditions
using sliced onion, dry pepper, sunlight, room temperature,
refrigerator and wood ash. Moisture and ash contents of the I.P
were determined using methods recommended by the Association of
Analytical Chemists (AOAC). The pH of LP was determined using pH
meter while titratable acidity was determined by titration
method. The potato rots were cultured on potato dextrose agar
and incubated at temperature between 26°C to 28°C. The fungi
isolated were identified using standard cultural and microscopic
methods. The total protein analysis of the I.P skin was carried
out using Sodium Dodecyl Sulphate Poly-Acrylamide Gel
Electrophoresis (SDS PAGE). Fusarium solani has the
highest isolation rate 40%, followed by Fusarium oxysporum
(26.7%), Aspergillus niger (23.3%) and Penicillium
spp (10%). Sliced onion has the highest values of rot
(52%) while wood ash has the lowest value of rot (10%). The
results also showed that the mean pH value of rotten and
un-rotten I.Ps were 5.28 and 6.58 respectively while the mean
moisture values of rotten and un-rotten I.Ps were 77.54% and
72.07% respectively. The t-values of intrinsic factors of I.Ps,
mean pH and moisture were 4.81 and 14.01% respectively. No
significant difference was found between the mean value of pH
and moisture contents of I.P (P>0.05). The proteomic analysis of
the skin of rotten and un-rotten LPs showed that their relative
mobilities were 0.558 and 0.465 respectively while
their molecular weights were 38.5kg and 53.0kg
respectively. The results of this study showed that the higher
the moisture contents the lower the pH value of the I.Ps and
also the more the fungal spoilage. Wood ash is recommended to be
an appropriate storage technique for I.Ps.

Abstract:
Rhizobia are soil-borne bacteria
that form nodules with legume roots and convert nitrogen into
ammonia. Legume plants are often a major part of native or
agricultural ecosystems, which increas nitrogen in low fertility
soils, e.g. saline soils. The major target of this study was to
characterize salt-tolerant rhizobial strains with high symbiotic
efficiency. We choose ten strains of rhizobia that were
previously mutagenized. Obtained results showed that 40 krad
was the highest dose of gamma rays supported by tested strains.
The irradiated clones at 50 krad were more tolerant to salt
stress compared to control strains, which proved that gamma
irradiation was effective in changing physiological and
phenotypic characteristics via random mutations. The rhizobial
strains treated with gamma rays were investigated using randomly
amplified polymorphic DNA profiles to differentiate the DNA
patterns among gamma treated rhizobia and parental strains. The
RAPD profiles showed different, similar or even the same RAPD
patterns for both types of rhizobial strains. The increase of N2
fixation parameters with some mutants was related to tolerance
acquisition that protects effective symbiosis against damage
induced by abiotic stresses. Inoculation with mutant isolates
resulted in higher total nitrogen content than parental
strains. According to the results of this study it can be
recommended that inoculation of Vicia faba with effective
Rhizobium strains can result in significant increase in
yield due to higher nitrogen fixation ability.

Abstract:
Fish is the most important source of animal protein food for the
human population and the potential of fish culture production
from ponds, floating cages and various other small water bodies
in India is great. The supply of quality fish seed is a key
factor to the expansion of fish farming. Fish seed demand at
present is strong, unsatisfied and expected to expand and fish
seed business in India is profitable. This review, based on
existing literature and field survey, provides clear
understanding of the current status of freshwater fish seed
resources for aquaculture development in Uttarakhand. The review
includes information relating to: (i) fish seed resources and
supply, (ii) fish seed production facilities and seed
technology, (iii) fish seed management and seed quality, (iv)
Induced breeding. Based on the above information, the emerging
challenges in Uttarakhand freshwater fish seed sector are
identified as: (1) broodstock management and species
identification, (2) human capacity and training needs, (3)
monitoring and evaluation, and indicators.

Abstract:
The aim of this study was to assess the microbial quality of
fish and hygienic status of fisher market in Ed Dueim city,
White Nile state, Sudan. Three fishes were selected, commonly
named Polti (Tilapia niloticus), Debs (Labeo niloticus)
and Kass (Hydrocynus spp.). Viable
bacterial count was determined by Pour plate method, while
coliform and fecal coliform were determined according to the
Most Probable Number (MPN) techniques. Total Viable counts of
bacteria and Staphylococci in fishes Skin were ranged from 2.8 x
103 to 9.8 x 104cfu/g and 0.0 to 7.2 x 102
cfu/g, respectively. The total count of
Yeast and Moulds ranged from 0.0 to 5.3 x 102cfu/g
while coliform and fecal coliforms were ranged from 15 to
120MPN/100g and 3 to 95MPN/100g, respectively. However, in
fish’s intestine the viable bacteria, Staphylococci and (Yeats &
Moulds) counts were ranged from 1.5 x 103 to 8.4 x 104cfu/g,
0.0 to 8.0 x 102cfu/g and 0.0cfu/g to 3.7 x 103cfu/g,
respectively. Total coliform and fecal
coliform were ranged from 20 to 150MPN/100g and 0.0 to
75MPN/100g, respectively. The results revealed 8 genera of
bacteria: Enterobacteriaceae, Bacillus, Pseudomonas,
Staphylococcus, Micrococcus, Streptococcus, Acinetobacter
and Moraxella in Skin's samples. The same genera were
obtained from intestine samples. Among these isolates,
Enterobacteriaceae [13(22.0%), 13(21.0%)] was the most
prevalence isolated from skin and intestine, respectively.
However, the least dominant isolate was Acinetobacter
2(3.4%) in skin and Moraxella 4(6.4%) in the intestine.
The results also showed the detection of Samlonella and
Shigella indifferent rate in some fish samples (skin and
intestine). According to the finding from this study, the fishes
examined were potentially contaminated with the pathogenic
microorganisms. Therefore, fishes should be appropriate
handling, cleaned, washed and cooked before consumption.

Abstract:
This research was initiated with the objective of developing
water management strategies to Siwa Oasis to ensure its
sustainable development. This is carried out by proposing and
testing chain water management scenarios that makes use of
suitable water (multiple reuses) before it reaches the last
disposal point. The results indicated that this specific type of
water management can add about 9,000 feddans to the presently
cultivated area in Siwa Oasis as a result of water saving
without any additional groundwater. Accordingly, the
productivity of each unit of groundwater will be achieved along
with reducing the non-productive area which is presently
occupied by the salt lakes.

The Relationship between Balanced

Fahim_721@yahoo.com
Abstract:
This study attempts to investigate the relationship between
characteristics of Balanced Scorecard (BSC) and innovation. To
this end, BSC literature is reviewed and then three basic
characteristics are extracted: diversity of performance
measures, balanced use of performance measures, and strategic
linkage of performance measures. Based on the premises of the
relationships between each characteristic of BSC and innovation,
three hypotheses are formulated. The hypotheses are empirically
investigated by data collected from most active one hundred
companies listed in Egyptian Stock Exchange. Findings indicate
that diversity of performance measures is not sufficient in
itself to stimulate innovation, unless both financial and
nonfinancial measures are used in a balanced manner, and
causally linked to the firm’s strategy. This is consistent with
BSC philosophy. The results also indicate that Egyptian
companies still give priority to financial metrics over
nonfinancial metrics. This weakens the ability of these
companies to innovate. The study also reveals that financial
metrics are not associated with innovation unlike nonfinancial
metrics.

Abstract: Human beings are
living in an epoch which has intrinsic complexities. Complexity
is a crucial factor both in natural phenomenon and the manmade
ones. We ought to be acquainted with complicated matters to
encounter the extant world and to know ways of dealing with it.
Once there was an epoch in which Kepler, Galileo and Newton’s
discoveries definite scientific features ruled the world of
science. Some hypothecations denoted that physical apparatuses
are pinpoint able.
Therefore it is feasible to foresee their future based upon
their past conditions. Such hypotheses opened novel vents in the
ruling paradigms of that epoch. They congregated plenty of
followers around themselves. Such conclusive views were
attractive and thrilling not only for pundits but also for the
canaille. They heralded a reliable predictable future. These
attitudes evinced that there was no unreliability and everything
abided by the cause-and-effect pattern. Einstein’s relativity
hypothesis which was actually a generalized version of Newtonian
mechanics furthered the prognosticated features of phenomena.
The predicament named “undeterminedness” was propounded in the
quantum physics. We happen upon some phenomena in quantum
physics whose future situation portending is difficult even if a
precise quantification contraption is utilized. These are the
circumstances in which we ought to resort to statistics and
probabilities. Once Heisenberg promulgated that human beings
will never be capable of overcoming the undeterminedness tenet
as long as quantum mechanics is valid. Some endeavors are made
in this article to define three concepts named “chaos”,
“complexity” and “catastrophe” in the nundination settings to
counteract such conditions. Organizational sensibleness in a
complicated setting is collated with Adizes organizational
maturity level.

his live. Because burullus lake is polluted with industrial
waste products and because fish present in this polluted water
and can’t escape so, the aim is to assess effect of this
pollution on fish organs and assessment of heavy metals
impairments. Materials and Methods: two fish species from
two different water Burullus lake and Bahr Tira canal as
control used to assess kidney and liver function and
antioxidants in muscles and gills also heavy metals were
assessed in water of two different regions and both muscles and
gills. Results: show increase of liver and kidney
function tests level and decrease in catalase and glutathione
reduced activity in both gills and muscles in addition to
elevation of heavy metals levels in burullus lake specimens than
Bahr Tira canal specimens. Also some heavy metals show elevation
in gills and muscles of fish taken from Burullus lake as
general.
