حضرت أفلام رقيقة من TiO2 بطريقة SOL-GELعلى ركائز من الزجاج العادي باستخدام المحاليل الأولية من ثلاثي كلوريد التيتانيوم والأيتانول وهيدروكسيد الصوديوم وحمض كلور الماء والماء المقطر. لدنت الأفلام المحضرة حراريا عند درجات حرارة (500-400-300-200)لمدة ساعة واحدة.درست البنية البلورية للأفلام المحضرة والمعالجة حراريا بتقانة XRD .بينت الدراسة أن الأفلام المحضرة تتبلور وفق البنية البلورية (orthorhombic) . تم حساب ثوابت الشبكة البلورية ووجد أها تتوافق بشكل جيد مع بيانات بنك المعلومات JPCDS ومع بعض الأعمال العلمية.
The thin films of TiO2 were prepared by the Sol-Gel, on glass subtracts by using the following initial solutions: trichlorethylene titanium, ethanol, sodium hydroxide and hydrochloric acid and distilled water. The films were annealed at temperatures(200- 300- 400-500)c° for 1 hour. The structure of the prepared and annealed films were studied by XRD. The XRD rusltes showed that the films prepared crystallize according to orthorhombic Structure.Lattice constants were calculated and it was found that it was consistent with the data JPCDS and with some scientific works.

It was found that the values of porous structure factors vary according to the
method of preparation, the two samples prepared in the manner of thermal
disintegration. The total pore size is slightly increased, while the mean pore radius
decreases from 2.71nm to 2.37nm, in contrast to the two hydrothermal heating
samples.
The total pore size increases significantly to 0.553ml /g. (SLS), a decrease in the
radius of the middle pores, and an increase in the value of the surface area.
In the present paper, we discuss the influence of point defects on electrical and
optical characteristics of ZnO thin films grown by the atomic layer deposition (ALD)
method on glass and silicon substrates at low temperature (100°C). Room temperatu
re
photoluminescence (RT PL) spectra, secondary ion mass spectroscopy (SIMS), and Hall
Effect measurements were made for as-grown ZnO layers. The annealing process was
performed in air as well as in N2 atmosphere at 400°C for half an hour. The long annealing
resulted in a larger reduction in electron concentration. Simultaneously, an evident
increase in carrier's mobility was observed, which may suggest that annealing resulted in a
decreased number of native defects in the ZnO layers. Also, it was observed that hydrogen
atoms in ZnO samples did not dominate their electrical properties with the increase of
electrons concentration.
In this research we have prepared thin films from poly vinyl chloride (PVC) by spin
coating technique in three velocities (1000,2000,3000)RPM on glass substrate (Micro
scope cover glass), at room temperature. The absorbance A, and transmittance T f
or the
films were studied in the visible and ultra-violet region (UV-VIS). In addition,we have
calculated the absorbance coefficient α, skin depth δ, refractive index no, dielectric
constant ε (the real part and the imaginary part), also we have calculated the energy band
gap of allowed and forbidden direct transitions.
The films showed high transmittance (80-90)%, in the infrared region as a function
of the spinning velocity and took the maximum value 80% for the velocity 1000RPM, and
90% for the velocity 3000RPM, and the refractive index was decreased with the velocity
increase, we found it between3.67 and 4.56 for the velocities 3000RPM and 1000RPM
respectively. Whereas the skin depth δ decreased with the increasing of velocity, the
minimum value was 0.0000531cm for the velocity 3000RPM and the maximum value was
almost 0.00023cm for the velocity 1000RPM.

The research was conducted on 24 ewes of Awasi sheep. The
animal study were divided into 4 groups each includes six ewes.
The first three groups were injected via variant proportions of
BST hormone ( as serial doses 40 mg, 80 mg, and 120 mg)
dail
y for 2 weeks. The fourth group was considered as control
group. It was measured the quantity of morning milk and
measurement of fat and protein and lactose one time every
week. Tissue specimen was taken from udder to study the
changes of secretive vesicles.
