Recent work has shown that fine-tuning large networks is surprisingly sensitive to changes in random seed(s). We explore the implications of this phenomenon for model fairness across demographic groups in clinical prediction tasks over electronic hea
lth records (EHR) in MIMIC-III ------ the standard dataset in clinical NLP research. Apparent subgroup performance varies substantially for seeds that yield similar overall performance, although there is no evidence of a trade-off between overall and subgroup performance. However, we also find that the small sample sizes inherent to looking at intersections of minority groups and somewhat rare conditions limit our ability to accurately estimate disparities. Further, we find that jointly optimizing for high overall performance and low disparities does not yield statistically significant improvements. Our results suggest that fairness work using MIMIC-III should carefully account for variations in apparent differences that may arise from stochasticity and small sample sizes.
The important processes that follow the harvesting of various agricultural crops, especially
the cereal crops, the process of sifting and separation of seeds from impurities, in order to
get rid of the impurities that exist with the seeds in the fi
rst degree, and to get rid of the
distorted and damaged seeds in the second degree.
This study was aimed to study the effect of the sieve holes of a local industrial electric
screening machine in the process of sifting and cleaning the seeds of some cereal crops,
and evaluation the performance of this machine, and then determining the optimal sieve
diameters for the seeds of crops studied and economically important in Syria.
The active part of the machine, called the vibrator, consists of three layers of sieves and
four gutters, the first sieve to get rid of large impurities (gravel, cloths, ...), the second
sieve to extract the very large seeds, the third sieve moves the seeds to the graphite
machine, It produces soft impurities (broken and small seeds).
The second sieve was studied. The results showed that the best sieve of the cumin seeds
with holes (0.8 mm) compared with actually used the sieve (1 mm). The best sieve seeds of
holes (1.25 mm), compared with actually used the sieve (1.40 mm). The best sieve for
local lentil seeds with holes (2 mm), compared with actually used the sieve (2.5 mm). The
best sieve of chickpea seeds with holes (5 mm) compared with actually used the sieve (5.5
mm).
Therefore, it is recommended to use the sieves with the holes shown above to screen the
studied seeds instead of the actual sieves used in the screening factories due to their
inaccuracy in the screening process because the diameter of these holes is not consistent
with the sizes of the studied seeds.
Orange fruits contain many materials such as oils in seeds which
have biological and nutritional values, due to that, physical and
chemical properties of orange seed oil (OSO) have been
determined, which extracted from two samples collected from two
areas (Al-ssisanyah and Al-jma'ashyah) which are different in
environmental factors.

The research was conducted on 25male lambs of Awassi
sheep to compare the effect of using different levels of whole cotton
seeds (WCS). The experiment extended for 70 days.
The research was conducted on 25male lambs of Awassi
sheep to compare the effect of using different levels of whole
cotton seeds(WCS). The experiment extended for 70 days,
experimental units were rested, then left for an adaptation period of
10 days, during the adaptation period, the animals were housed in
one pen, in the end of the adaptation period, the lambs were
individually weighed, then divided according to live weight into six
equal groups of an average weights (24-25) kg each.
This study investigated the effect of the water extract of two types
of algae which spread in Syrian marine: Colpomenia sinuosa
(Brown) and Ulva fasciata (green) and a combination of them in
the cultivation on tomato and tobacco seeds with concent
rations of
(1: 2 1: 4 1: 6 1: 8 1:10 1: 20) By adding 5ml of each
concentration, and comparing it with the control sample with only
distilled water added, the comparison was made in terms of: The
germination, stem length, root length, root branch.
The phenolic compounds were extracted from leaves and flowers of Hops and grape
seeds from local production by soaking with different solvents (Methanol-ethanol-alcohol
and water mixture) . The polyphenols content in the methanol extracts for 100 g
dry matter
was 6.31 g for the grape seeds, 2.08 g for Hops leaves and 0.6 g for Hops flowers.
Methanol extracts were characterized by an antioxidant activity that appeared by their
ability to Reduce ions ferriques Fe+3, at a concentration of 2500 ppm, the Reducing Power
was 96.45% , 67.56% for the grape seeds and Hops leaves, respectively. The methanolic
extracts of grape seeds and Hops leaves at 80 ppm showed activity in scavenge free radical
DPPH. was 82.04% and 40.92% respectively. The methanolic extracts of grape seeds and
Hops leaves at 250 ppm gave the ability to protect linoleic acid from the oxidation process
of 78.98% and 48.41%, respectively. The antioxidant activity values of the extracts were
compared with standard samples of ascorbic acid and BHT.
Adding the sifting meals of the Avocado seed to wheat flour mixtures caused
increasing in folowing percentages of components: (moisture , fibers , ash , starch and total
soluble sugars )
Also the (5,10%) percentages adding caused a slight reducing
in gluten quality ,
while a reducing in gluten quality was clearly at (15 , 20%) percentages.
Also the adding of tested meals caused improvement in baking quality (loaf weight
during baking and during cooling) , also improvement the sensory properties of produced
bread significantly , except (20%) percentage comparing with control sample.
Finally , 15 and 20 percentages , only of Avocado seed meals adding caused
reducing in taste property of produced bread.
This research was carried out during two seasons 2014 – 2015 to study effect of seed
coats on germination of endocarp, seed and embryos of two wild genotypes (M1, M2) of
Mahaleb rootstock (Prunus mahaleb L.) prevailing in Alhaffa area, Lattakia. Th
e
experiments were done at Lattakia Scientific Agricultural Research center and Faculty of
Agriculture at Tishreen University.
The Results of the seeds planted on agar 0.7% in dark at 15 C° showed that no
germination of the M1 endocarp VS late and low germination at 10% for the M2 endocarp
starting after 98 days. As for seeds, the germination was (66.66%) and (53.33%) for M1
and M2, respectively. Removal of the woody coat (endocarp) and seed coat makes the
germination faster. the embryos germination was (80%) and (60%) for M1 and M2,
respectively.
