Abstract
The increasing of temperature with reduction of rainfall in dry season led to reduce water areas which cause reduce the cultivation areas in Iraq and other countries. Effecting of drought ...causing negative action on crop productivity. The irrigation water shortage will impact on crops by stress of water as well water decreasing will increase salt concentration that will increase the salt stress cause influence on yield of crops. This research will study of stress by decreasing of water (deficit irrigation) on production of okra crops with both use subsurface water retention techniques (SWRT) and without use SWRT, then estimation differences after that calculate affection of salt on crop. The research was done in Babylon governorate in Al-Hindiya Barrage. The treatments A1 used drip irrigation system with SWRT technique and used deficit irrigation in some times, while A2 used trickle irrigation without SWRT and use deficit irrigation in some times. The results of treatment A1 showed the amount of applying water reduced to 7% than A2. Whereas the number of irrigations of A1 equal to A2. The yield of crop of A1 was more than of A2 by 15 %. The actual yield of A1 was impacted by water stress and salt were 0.01 kg/m2 and 0.011 kg/m2 respectively. The actual yield of A2 which impacted by water stress and salt were 0.079 kg/m2 and 0.085 kg/m2, respectively. The yield in A1 with SWRT and without stress and the yield of A2 without SWRT and without stress showed percent of increasing of 2.3%. The SWRT technique helps to stress resistance and drought resistance by using okra of loam soil.
Abundance and diversity of benthic macroinvertebrates as well as physico-chemical parameters were investigated in five rivers of the Juru River Basin in northern Peninsula Malaysia: Ceruk Tok Kun ...River (CTKR), Pasir River (PR), Permatang Rawa River (PRR), Kilang Ubi River (KUR), and Juru River (JR). The physico-chemical parameters and calculated water quality index (WQI) were significantly different among the investigated rivers (ANOVA,
P<0.05). The WQI classified CTKR, PR, and JR into class III (slightly polluted). However, PRR and KUR fell into class IV (polluted). High diversity and abundance of macroinvertebrates, especially the intolerant taxa, Ephemeroptera, Plecoptera, and Trichoptera, were observed in the least polluted river, CTKR. Decreasing abundance of macroinvertebrates followed the deterioration of river water quality with the least number of the most tolerant taxa collected from PR. On the basis of composition and sensitivity of macroinvertebrates to pollutants in each river, the highest Biological Monitoring Working Party (BMWP) index score of 93 was reported in CTKR (good water quality). BMWP scores in PRR and JR were 38.7 and 20.1, respectively, classifying both of them into “moderate water quality” category. Poor water quality was reported in PR and KUR. The outcome of the multivariate analysis (CCA) was highly satisfactory, explaining 43.32% of the variance for the assemblages of macroinvertebrates as influenced by 19 physical and chemical variables. According to the CCA model, we assert that there were three levels of stresses on macroinvertebrate communities in the investigated rivers: Level 1, characterized of undisturbed or slightly polluted as in the case of CTKR; Level 2, characterized by a lower habitat quality (the JR) compared to the CTKR; and Level 3 showed severe environmental stresses (PRR, PR, and KUR) primarily contributed by agricultural, industrial, and municipal discharges.
1. A stock of cross-bred CD hens was divided into 'resistant' (R) and 'sensitive' (S) to stress on the basis of the heterophil/lymphocyte (H/L) ratio using the lower 99% confidence limit method for ...selection. A first generation was produced from these R and S females mated with similarly selected R and S local Barred males. The association between 'resistance' and some production traits was investigated. 2. The proportions of R:S among CD females and Barred males was 51.2:48.8 and 52:48, respectively. Mean H/L ratios for Barred males and females, respectively, were 0.87 +/- 0.03 and 0.83 +/- 0.03 (P > 0.05). 3. Compared with the S group in CD females, the R group had greater egg production (59% vs 51%), egg weight (65.5 g vs 62.6 g) and body weight at 39 weeks (115 g heavier). 4. The superiority of R in terms of proportion of fertile eggs, hatchability and the proportion hatched from those set amounted to 4.8, 6.1 and 5.4%, respectively. 5. The proportion of dead embryos in the R group (5.4%) was lower than in the S group (9.3%). 6. With the F1 generation the R chicks were heavier at hatching. 7. Percentage mortality of male F1 chicks, from hatching to 4 weeks and from 4 to 8 weeks, was lower in the R group. A similar, but non-significant, trend was noted for R females. 8. The progeny of the R group was heavier than the S progeny at 4 and 8 weeks and also the percentage dressed weight of males was greater at 8 weeks. The R group was heavier than the S group at 4, 8 and 12 weeks. 9. These results suggest that selection for general 'resistance', on the basis of the H/L ratio using the 99% lower confidence limit method of selection, is positively correlated with several important production and reproduction traits. Establishing resistant lines with high production rates seems feasible.
Background: Consanguineous marriage is a relationship between biologically related individuals. Genetic factors have a role in gene environment interactions that takes the center stage. The evidence ...of oral disease (gingivitis and periodontitis) may depend on genetic syndromes, inherited diseases, familial studies etc. The present study aims at assessing dental plaque and gingival health condition in children of inbreeding parents compared with children of outbreeding parents among primary schools in Al-Qasem city/ Babylon governorate in Iraq. Materials and methods: this comparative study included three hundred ninety eight (398) students, 6-12 years old, from 4 primary schools; 199 children had their parents of inbreeding marriage with first level of inbreeding, and the other 199 children had parents of outbreeding marriage. Plaque status was assessed according to index of Silness and Loe (1964), gingival health status according to index of Loe and Silness (1963). Results: Children of inbreeding parents showed significantly higher plaque index and gingival index mean values than children of outbreeding parents. Mild gingivitis was found as the most prevalent type among both groups. A highly significant positive correlation was found between gingival and plaque indices. Conclusion: Inbreeding rates have an effect on oral health, as the children of outbreeding parents had significantly better oral hygiene and gingival health condition than children of inbreeding parents.
Abstract
Currency is one of the most frequently passed items in the world. It used every day and every way, and it could act as an important vehicle for cross-contamination. This research was aimed ...to determine how long pathogenic bacteria can survive on currency paper, four pathogenic bacteria including
E. coli, Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis
were provided according to laboratory standard methods. Sterile pieces of currency paper were inoculated with the pathogenic bacteria and the survival of bacteria was tested over seven days. The results showed that all tested bacteria differed in time of survival and this survives according to environmental conditions, the type of bacteria and the mode of its resistance, but they were stable and still cultivable after seven days. The second part of this research was to design a simple experimental model to check the efficacy of germicidal and attempted to use ultraviolet light radiation to evaluate the inhibitory effect of most pathogenic microorganisms on currency as a disinfectant. The results revealed that UV is an effective tool, so we recommend using it as a disinfectant for currency.
A new Schiff base I was prepared by refluxing Amoxicillin trihydrate and 4-Hydroxy- 3,5-dimethoxybenzaldehyde in aqueous methanol solution using glacial acetic acid as a catalyst. The new ...1,3-oxazepine derivative II was obtained by Diels- Alder reaction of Schiff base I with phthalic anhydride in dry benzene. The reaction of Schiff base I with thioglycolic acid in dry benzene led to the formation of thiazolidin-4-one derivative III. While the imidazolidin-4-one IV derivative was produced by reacting the mentioned Schiff base I with glycine and triethylamine in ethanol for 9 hrs. Tetrazole derivative V was synthesized by refluxing Schiff base I with sodium azide in dimethylformamid DMF. The structure of synthesized compoundsI-V was characterized by their melting points, elemental analysis CHN-S and by their spectral data; FTIR and 1H NMR spectroscopy. Two cancer cell lines include: (RD) human pelvic rhabdomyosarcoma and (L20B) the mice intestines carcinoma cell line (which expresses the genes for human cellular receptor for Polio viruses) were used in this study. The cytotoxic effect of different concentrations of all the synthesized compounds for 48 hrs was examined. All compounds except IV and V showed less than 50% inhibition for (L20B), while these compounds exhibit inhibition more than 50% inhibition for (RD).
Clinical microdialysis enables monitoring of the cerebral extracellular chemistry of neurosurgical patients. Introduction of the technique into different hospitals' neurosurgical units has resulted ...in variations in the method of application. There are several variables to be considered, including length of the catheter membrane, type of perfusion fluid, flow rate of perfusion fluid, and on-line compared with delayed analysis of samples. The objects of this study were as follows: 1) to determine the effects of varying catheter characteristics on substance concentration; 2) to determine the relative recovery and true extracellular concentration by varying the flow rate and extrapolating to zero flow; and 3) to compare substance concentration obtained using a bedside enzyme analyzer with that of off-line high-performance liquid chromatography (HPLC).
A specially designed bolt was used to conduct two adjacent microdialysis catheters into the frontal cortex of patients with head injury or poor-grade subarachnoid hemorrhage who were receiving ventilation. One reference catheter (10-mm membrane, perfused with Ringer's solution at 0.3 microl/minute) was constant for all studies. The other catheter was varied in terms of membrane length (10 mm or 30 mm), perfusion fluid (Ringer's solution or normal saline), and flow rate (0.1-1.5 microl/minute). The effect of freezing the samples on substance concentration was established by on-line analysis and then repeated analysis after storage at -70 degrees C for 3 months. Samples assayed with the bedside enzyme analyzer were reassessed using HPLC for the determination of glutamate concentrations.
Two adjacent microdialysis catheters that were identical in membrane length, perfusion fluid, and flow rate showed equivalent results. Variations in perfusion fluid and freezing and thawing of samples did not result in differences in substance concentration. Catheter length had a significant impact on substance recovery. Variations in flow rate enabled the relative recovery to be calculated using a modification of the extrapolation-to-zero-flow method. The recovery was approximately 70% at 0.3 microl/minute and 30% at 1 microl/minute (10-mm membrane) for all analytes. Glutamate results obtained with the enzyme analyzer showed good correlation with those from HPLC.
Homozygous variants of the thrombospondin type‐1 domain‐containing 1 (THSD1) gene have recently been associated with nonimmune hydrops fetalis (NIHF; OMIM 236750) in infants, as well as with ...congenital heart disease, hemangiomas, prematurity, and embryonic lethality. Here, we report the first case of a biallelic variant of THSD1 in an extremely premature infant (25 weeks) who suffered from NIHF (eventually resolved) and other manifestations of the THSD1 variant, such as congenital heart disease and hemangiomas. Her prematurity was complicated by pulmonary hypertension and chronic lung disease. This case indicates that biallelic homozygous variants of THSD1 are among the likely causes of NIHF. Information from this case report will aid in determining the prognosis of NIHF caused by such variants in premature infants.
During the spring season of 2021, a field experiment was conducted at the College of Agricultural Engineering Sciences - University of Baghdad (Abi Ghraib location). To investigate the impact of nano ...iron concentrations and their application dates on the yield and its components of maize. A factorial experiment was carried out in a split-plot arrangement. The main plots occupied the spraying dates (beginning of the male flowering stage, 50% female flowering and completion of female flowering) and symbolized in sequence. At the same time, the iron concentrations (0, 100, 200 and 300 mg. L-1) occupied sub-plots according to RCBD with three replicates. The results revealed that the dates of spraying nano iron substantially influenced most of the features tested. The early date (beginning of the male flowering stage) gave the highest average length of the ear (16.374 cm), the number of rows per ear (16.3 row ear-1), and the number of grains per ear (563.4 grain ear-1) and the total grain yield of 6.096 tons ha.-1. The results also showed that the concentrations of nano iron 300 mg L-1were superior in all the characteristics of the yield components and the grain yield, as it produced the most significant average for ear length, number of rows, number of grains per row, number of grains in the ear, weight of 500 grains, and total grain yield. It is concluded from this study that spraying at the beginning of the flowering stage is the most responsive to spraying the nano iron element, especially at the concentration of 300 mg L-1.
