Abstract

Dermatophyte fungi of the genera Trichophyton, Epidermophyton, and Microsporum infect human skin, hair, and nails.
These types of infections, termed "dermatophytoses," are widespread that affects billions of individuals worldwide. In
the present study, we isolated Trichophyton mentagrophytes from patients with dermatophytoses. The isolates were
grown on Sabouraud agar and were identified on the basis of microscopic examination, for the presence of fungal
elements. To promote production of protease, T. mentagrophytes isolate cultured in protein liquid medium. Results
showed that T. mentographytes have ability to produce extracellular protease which indicated by proteolysis activity
111.9 U/ml against casein when added as substrate to the culture filtrates of T. mentographytes with specific activity
2238U/mg. To optimize protease production by T. mentographytes, the effect of different cultural conditions
(production media, incubation period, optimal temperature and pH) on production of extracellular protease were
studied. The results showed that T. mentographytes have high ability to produce protease after 9 days of incubation in
protein liquid media at 30 °C, and pH 7.0. The extracellular protease synthesized by T. mentagrophytes extracted, then

Abstract

Novel N2O2 type Schiff base and its metal complexes of Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) have been synthesized
from the Schiff base (H2L) 4[N-(2-hydroxyacetophenone)imino]antipyrinyl-2-amino-2methyle-1-propanol derived
from 4-aminoantipyrine, o-hydroxyacetophenone and 2 – amino – 2 – methyl – 1 - propanol. Structural features of the
complexes have been deduced from metal analyses, infrared, electronic spectra, magnetic susceptibility and
conductivity measurements. All complexes were found to have the composition of [ML] type. IR spectra show that the
ligand is coordinated to the metal ions in a tetradentate manner. The electronic and magnetic susceptibility data of the
complexes suggest a square planar geometry around the central metal ion. The molar conductance data reveal that the
complexes are non-electrolytes.

addition to chert fragment. Monocrystalline and polycrystalline quartz also exist in 17-30%, feldspar rarely occured.
The heavy minerals biotite, hornblende, rutile, muscovite and opaque minerals also present. The high percentage of
carbonate rock fragments indicate that they derived from the older carbonate such as Fat'ha and other older carbonate
formations

Abstract

This study reveals the orthogonal structure of Amphicotylo heteropleura cestode tapeworms by using the enzymatic
method with (Achi) technology. The results show that the cholinergic compound for regular orthogonal consist of two
pairs of brain ganglia which are located the revoluted elongated head with associated organs like posterior ring which is
similar to the accessory sucker, in addition to the apical disc. On of this posterior long cerebral ganglia located near the
cestoda body characterized with its elongated shape , arise from it two pairs of thick lateral nerve trunks, the other is
anterioly located arise from it five pairs of thin median nerves and four pairs of lateral nerve cords. Thick nerve trunks,
lateral nerve cords , and thin median nerves are connected together by a number of transverse commissures , which are
different in number according to the number of body segments. Moreover, this study reveals the distribution of
posterior lateral ganglia along the thick lateral nerve trunks, lateral nerve cords and thin median nerves. This cestode is
characterized by appearance of nerve net in each segment that ends by sensory ganglia which have a good reaction to
(Achi) technology, this net extends to the borders of the body , the cholinergic components extended deeply into the
tissues of the reproductive organs and other functional units to supply it with nerves and to make a nerve mechanism to
continue its life.

Abstract

This paper shows that under regularity conditions and if
1 Yn Y ,.......,
are iid from a k–parameter regular exponential
family with complete sufficient statistic
n
with
   
( ) n
, then
(   ) ~  (0,()) n n  k
where
()
is the
information matrix of the natural parameterization of the family. And also we can use the delta method in finding the
Expectation and Variance for the complex function . In this paper, I generate random numbers for 2 continuous
distributions and 2 discrete distributions which belong to the Exponential Family, the result of Simulation appears that
the Central Limit Theorem has a good approximation for the Normal distribution .
