The field experiment was conducted with the aim of developing and testing an automatic sprayer for agricultural spray experiments and studying the effect of spray pressure, spray speed and spray height on the spraying process. The effects of the major spraying factors (pressure, speed, and height) on the spraying performance of the automatic sprayer were studied. This study included several traits: First - the drop sizes - Second - the penetration of the spray into the vegetation cover - Third, the spray wasted. The results showed: - First: - Increase in coverage percentage when using the first speed, 2 km / h, which amounted to 26.85%. An increment in the spraying penetration of the vegetation cover was observed at the second speed

The morphological description and histological structure of the

olfactory     organ     of    Parasilurus     triostegus     (Heckel)     have    been

investigated. The olfactory organ situated on the dorsal surface of the

head infront of the eye.

It  is  represented   by  elongated  olfactory  sac,  in  which  the

olfactory Lamellae arranged as Rosette- like pattern .

The olfactory sac connected with the olfactory bulb by short olfactory nerve. The olfactory bulb which situated near the olfactory sac connected wi

It is well known that the spread of cancer or tumor growth increases in polluted environments. In this paper, the dynamic behavior of the cancer model in the polluted environment is studied taking into consideration the delay in clearance of the environment from their contamination. The set of differential equations that simulates this epidemic model is formulated. The existence, uniqueness, and the bound of the solution are discussed. The local and global stability conditions of disease-free and endemic equilibrium points are investigated. The occurrence of the Hopf bifurcation around the endemic equilibrium point is proved. The stability and direction of the periodic dynamics are studied. Finally, the paper is ended with a numerical simul

Hypertension is a cardiovascular problem with high rates of epidemiology and risks of morbidity and mortality in the global area. Nitric oxide (NO) is one of the reactive oxygen species (ROS) that produced from L-arginine by nitric oxide synthase (NOS) enzyme. NO involves in various vital processes in human health, one of which is the modulation of vasoconstriction and relaxation of the vascular system. We have aimed to investigate the link between NO and NOS with hypertension in women. The relationship between NO and NOS, as well as the usefulness of them as indicators of hypertension risks were subjects of study in this article. The results have revealed that hypertensive women had significant (P<0.05) lower levels of NO (15.07±3.41 IU/m

One hundred and six S. aureus were isolated from 250 Nasal swabs of
Healthcare workers and patients at Al- Kadhamia teaching Hospital and Al-
Numan hospital, Baghdad, Iraq. The study was undertaken over a period of
ten months between August 2011 and June 2012. S. aureus isolates were
diagnosed based on phenotypic traits and biochemical tests. Antibiotics
sensitivity to 11 antibiotics, revealed that S.aureus is totally resistant to
Pencillin G (100%), highly resistant to Cefoxitin (alternative to Methicillin)
(94.3%) While there are varied resistance percentage for the rest of
antibiotics: Erythromycin (37.7%), Tetracycline (34.9%), Gentamicin
(29.3%), Trimethoprim/sulfamethoxazole (50%), Ciprofloxacin (29.2%),<

The present study represent the histological and histochemical structure of the esophagus of laughing dove Streptopelia senegalensis, one of the wild birds, which feed on the seeds( grainvorous).The result showed that the esophagus long tubular quit wide and highly distensible organ situated at the right side of the nick , lie between pharynx and stomach it was divided into cervical and thoracic part , the cervical part longer than the thoracic part, and the crop was merely enlargement fusiform in shape which located at the entrance of the thorax. Esophagus parts showed that composed of four layer ;the mucosa, sub mucosa, muscular and adventitia or serosa, the mucosal layer was arranged in folds which was longer in the c

  The morphological description and histological structure of Kidney in barn owl Tyto alba have been invesigated. The results of present study revealed that barn owl has pair of elongated solid kidney situated symmetrically on both sides of vertebral column. Each kidney consists of three lobes represented by carnial, middle and caudal lobes and all of then covered by a capsule of connective tissue.     Microscopical examination showed that the basic unit of kidney in barn owl represented by lobules which have conical shaped and each of them consists of cortex and medulla, and the cortex occupies more area than that of medulla. The results of the present study revealed that the glomerulus in barn owl represented b

Background: Oral Lichen Planus is a chronic inflammatory mucosal disease, presenting in various clinical forms .Both antigen-specific and non-specific mechanisms involved in the pathogenesis of OLP. Apoptosis or programmed-cell death is a physiological process essential for the normal development and maintenance of homeostasis in many organisms. Fas is a cell-surface glycoprotein, 40-kDa, that belongs to the nerve growth factor / tumor necrosis factor (TNF) receptor family. Fas is expressed in several tissues including blood, where its expression is upregulated on activated T and B lymphocytes and natural killer cells. Fas ligand is a type II transmembrane protein that belongs to the tumor necrosis factor family. The proto-oncogene c-Myc is
