Abstract:
Salinity is an international problem causing soil degradation
and desertification; thereby threaten sustainable crop
production in agriculture. Traditional methods of measuring
wheat growth have been time-consuming and have often involved in
the destructive harvest of plants. Thermal infrared imaging (IR)
is now an established technology for the study of stomatal
responses and for phenotyping the stomatal behavior under
various environmental stresses. Two Experiments were carried out
at the experimental farm of El Quantara Shark, Suez Canal
University, Ismailia, Egypt to test whether thermal imaging can
be used to distinguish between tolerant and sensitive wheat
genotypes. Ten bread wheat genotypes differing in salt tolerance
were evaluated under two soil salinity levels (EC =3.78 dS m-1and
EC= 8.24 dSm-1).
The salinity stress created a wide range in leaf temperature,
stomatal conductance (IG) and Crop Water Stress Index (CWSI) between tested genotypes. Proline content
increased by 13 fold in landraces 1, 2, 3and 10 folds in
genotypes Sakha 8 and Kharchia due to salinity stress.
There were inverse correlation between canopy temperature and
CWSI (r= -0.31) and IG (r = 0.53). Thermal imaging
can distinguish between salinity stress and non-stress canopies.
Therefore, the application of these technologies and
methodologies for efficient salinity managements in wheat open
new opportunities and challenges in future precision farming.

Abstract: Objective: The
purpose of this study is to determine the presence/degree of
sexual dimorphism of the 12th thoracic vertebra
through a quantitative analysis and to further examine its
potential and reliability in the sex estimation of human
skeletal remains. Method: In order to assess this, the 12th
thoracic vertebrae, 100 persons 51 males (age range 23-70 years)
and 49 females (age range 17-62 years) from Egypt. These persons
were patients who needed to undergo CT of the abdomen for
several reasons in the Radiology Departments of Minia University
hospital. CT studies were performed using a 16-detector
Multi-Detector Computed Tomography (MDCT) scanner .The
morphology of the 12th thoracic vertebra was examined
by nine measurements. Descriptive statistics, including means,
standard deviation and test of
significance were performed for each of the measurements. To
assess the level of significance in the mean values between the
sexes, t-test was applied and a value of P < 0.05 was considered
significant. Univariate and stepwise discriminant function
analysis were carried out respectively. Results: The coronal
diameter of vertebral body (BDc) and vertebral length (VL) are
found to be highly significant sexually dimorphic. The sagittal
diameter of vertebral body (BDs) and length of spinous process
(SL) showed high significant sexual dimorphism. While the height
of pedicle on right and left side (PHr & PHI) are significantly
sexually dimorphic. The highest accuracy was obtained with the
BDc (87%). Conclusion: The result of the present work showed
that the lih thoracic vertebra exhibits anatomic variability
between genders. 12th thoracic vertebra dimensions
measurements, especially the coronal diameter of vertebral body,
are valuable in studying sexual dimorphism.
