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 research was carried out at Jeb Ramlah Research Station – AlGhab Research Center - General Authority of Scientific Agricultural Research at 2017 growing season. The objective was to investigate the effect of three organic and bio fertilizers (B acillus, Humic acid and Amino acids) and three fertilization methods (Soaking seeds, Vegetative spraying and Plant irrigation) in some morphological and production traits of cotton cultivar 124 (Gossypium herutum L.) The experiment was conducted according to RCBD with three replications. The first factor (fertilizer type) occupied the main plots, while the second factor (fertilization method) occupied the split plots. Statistical analysis was carried out using the Genestat.12 software and the least significant difference L.S.D. at 5% level was calculated. Studied traits included (at the beginning of Blooming stage): Plant Height, Plant wet weight, Plant dry weight, Leaf area and plant production of cotton. The results showed that the average of treatment of amino acids was superiority significant on the others in terms of plant height (70.70cm), Plant wet and dry weight (201.50, and 83.41g), respectively, Leaf area (4240.15cm2/plant) and plant production of cotton (75.13g). For fertilization method, Vegetative spraying average was superiority significant on the others in terms of all studied traits.
A proper matching of agricultural machinery with properties of materials forms the essential requirements which lead to best performance of machine. To achieve that goal, availability of data and precision analysis on engineering and physical prop erties of these materials is required. This forms important and necessary data base for the design, development and structure of agricultural machinery and equipments, control and analysis of machines and determination of efficiency of machines. This research was carried out to study some engineering and physical properties of seeds of common Syrian crops to be used in the design and development of some agricultural machinery and equipments. Results provided the shapes and dimensions of cells of feeding devices for planting seeds of some crops namely, wheat, maize, lentil, pea, chick-pea, kidney bean, broad bean and cotton. In addition a set of empirical equations were established to be used to predict, with reasonable accuracy, the physical properties of crops seeds based on measurement of any of three dimensions (length, width and thickness).
The research was carried out during 2015 and 2016 seasons at Arab El-Mulk village, Banias district, in Tartous Governorate, to study the effect of planting peanut seeds size (mixture, small, medium and large), and spraying plants with bread yeast (Saccaromyces serevisiae) concentration of (4%) in three treatments (control, once and twice), on biological yield (BY), Economic yield (EY) and some physiological indicators; yield index (YI), Harvest index (HI), crop index (CI) and seed index (SI). The experiment design was set as split plot in a randomized complete block with four replications. The seeds size considered the main factor, while spraying yeast allocated the sub plots. The results showed that seed size caused significant increases in all of the studied indicators. The large seeds gave better values of (BY) 210 g, (HI) 30.56%, (CI) 44.12%, (SI) 74.85 g, except (EY) compared with mix, small and med seeds. Also the results showed that there were no significant increase between mixture and medium seed size in (YE) and (HI), but there was a significant increase in (BY) and (SI), on the other hand the treatments; spray yeast for once and twice had significant increases compared to the control, and the twice yeast spraying gave better values (215.22 g ,63.98 g, 29.64%, 42.37 % and 73.45g ) of (BY , EY ,HI, CI and SI) respectively, compared to the control. The interaction between seeds size and bread yeast spraying caused a significant increase which achieved 15.78 % in (BY), 23.99 % in (EY), 9.74 in (HI), 13.68% in (CY) and 7.87g in (SI) compared to the interaction between untreated treatment and small seeds size.
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.
The effect of different culture medias (water, MS solid, MS 1/2 solid) on germination and growth of heliotropiun hirsutissimum Grauer. in vitro was studied with different concentrations of gibberellic acid (0.001-0.01-0.1 and 1 mg/l). The results showed that best germination rate (80.5%) and root (20mm) and shoot (35mm) growth were obtained in MS solid medium with 0.1mg/l GA3. Addition of 0.1mg/l GA3 to MS1/2 solid medium improved germination rate (75.44%), root (19mm), and shoot (24mm)growth. When GA3 (0.1 mg/l) was added to water medium, germination rate reached (65.33%), as well as root and shoot growth (12.66mm and20mm) alternatively after 2 weeks of planting. Seedling of MS solid medium were transferred into pots contained torp medium to adapting them with outside environment, and then surviving their growth until maturity after 4 weeks.
