Effect of High Standard of Temperature on the Hardened Needled Concrete

Fibers are usually used to reinforce concrete. The study shows the using of needles for reinforcing high-strength concrete (60MPa) when the samples are exposed to temperatures (100°C and 400°C) with a percentage of needles (0%, 0.5% and 1%) compared with the conditions of room temperature (25°C). They study shows that the compressive strength decreases by about (0.94% and 17.6%) for (0% needle (steel fiber)) at 100°C and 400°C, respectively. The compressive strength decreases by about (1.7% and 15.9%) for (0.5% needle (steel fiber)) at100°C and 400°C, respectively. The compressive strength decreases by about (0.3% and 14.2%) for (1% needle (steel fiber)) at 100°C and 400°C, respectively. All the above-mentioned results are compared with cubes tested at room temperature (25°C). Based on the results of this work, the tensile strength decreases by about (0.49% and 6.65%) for (0% needle (steel fiber)) at 100°C and 400°C, respectively. The tensile strength decreases by about (0.73% and 6.1%) for (0.5% needle (steel fiber)) at 100°C and 400°C, respectively. The tensile strength decreases by about (0.24% and 5.54%) for (1% needle (steel fiber)) at 100°C and 400°C, respectively. All the above-mentioned results are compared with cubes tested at room temperature (25 °C). The flexural strength decreases by about (1.08% and 26%) for (0% needle (steel fiber)) at 100°C and 400°C, respectively. The flexural strength decreases by about (2.1% and 26.3%) for (0.5% needle (steel fiber)) at 100°C and 400°C, respectively. The flexural strength decreases by about (3.1% and 24.7%) for (1% needle (steel fiber)) at 100°C and 400°C, respectively. All the above-mentioned results are compared with cubes tested at room temperature (25°C)

Resumptive pronouns in Baha Arabic: an experimental study

The phenomenon of resumption has been a central topic of debate for both syntacticians and psycholinguists. The debate particularly centres on whether resumption is a syntactic phenomenon or a processing one and whether this characterization differs across languages (and dependencies). Theoretical and experimental investigations have revealed that resumption exhibits a great deal of variation across (and sometimes within) languages (Sells, 1984; Sells, 1987; Asudeh, 2004; McCloskey, 2006; Asudeh, 2012). This is further complicated by diverging interpretations of the data. Specifically, while the theoretical literature presents resumption as a wide-spread cross-linguistic phenomenon affecting longer distance dependencies and island-violating dependencies, this claim is not confirmed in experimental literature (Farby et al., 2010; Keffala, 2011; Tucker et al., 2019; Perpiñán, 2020, among others). This dissertation examines the phenomenon of resumption in Baha Arabic, a language with a productive use of resumptive pronouns across different types of dependency structures. It aims to investigate the theoretical literature’s argument that resumption is preferred to gaps in certain syntactic configurations (i.e. islands and longer dependencies) and to elaborate on the extent to which resumption in this variety of Arabic differs from resumption in languages like English. Four experimental studies, exploiting both offline and online methods, are conducted. The findings suggest that resumption in Baha Arabic is not a uniform phenomenon, despite the argument that it mainly has a syntactic function; (i) true RPs in illi-structures constitute part of the initial derivation in binding dependencies (as morpho-syntactic features of C do not trigger movement) and (ii) intrusive RPs in wh-questions are utilized as last resort devices to fix derivation problems when movement is illicit. The availability of intrusive RPs as a syntactic last resort device is restricted to wh-questions featuring inherently D-linked fillers ‘i.e. which-fillers’. This dissertation, furthermore, examines the extent to which the type of wh-filler phrase (which vs. what) affects the acceptability and processing of island-violating dependencies in Baha Arabic. Although no such claim had previously been made for Arabic varieties, we found that gapped island-violating dependencies with which- fillers are accepted more than gapped island-violating dependencies with what-fillers. This amelioration effect is interpreted as reflecting an extra-grammatical phenomenon. Though not the focus of the dissertation, our findings suggest that islands are neither a purely syntactic nor a purely processing phenomenon and that a combination of both cognitive and syntactic constraints contribute to it

Exact Ordering

 Ordering is an important subject of learning; it has so many applications in day -to - day life. Hence, in this paper exact and general exact ordering methods are reviewed giving sample applications for them. Firstly, the exact ordering method is introduced and few theorems are given to assign the conditions needed to locate the position of a required object among a class of objects to be ordered in a certain manner in three classes. Secondly, the exact ordering method is generalized to any odd number of classes  In both cases and if the required object class is put in the middle of other classes, then the required object will be located exactly in the middle of all objects provided that we arrange the objects orderly in three classes in the first case and in ones in the second general case and where certain defined steps are to be followed.In general  steps are required to determine the required object exactly and where  is the odd number of classes. Making the subject more interesting, deeper, and handled in a sophisticated manner, through the introduction of exact ordering operators, is then exposed to. Finally, few different applications are suggested in physics, operational research, criminal investigation and in sorting files and postal mailing. A practical demonstration with playing cards is also mentioned

Gene frequencies of ABO and rhesus blood groups in Sabians (Mandaeans), Iraq

The present study aimed to determine the frequency of ABO and Rh blood group antigens among Sabians (Mandaeans) population. This paper document the frequency of ABO and Rh blood groups among the Sabians (Mandaeans) population of Iraq.There is no data available on the ABO/Rh (D) frequencies in the Sabians (Mandaeans) population. Total 341 samples analyzed; phenotype O blood type has the highest frequency 49.9%, followed by A 28.7%, and B 13.8% whereas the lowest prevalent blood group was AB 7.6%. The overall phenotypic frequencies of ABO blood groups were O>A>B>AB. The allelic frequencies of O, A, and B alleles were 0.687, 0.2 and 0.1122 respectively. Rhesus study showed that with a percentage of 96.2% Rh (D) positive is by far the most prevalent, while Rh (d) negative is present only in 3.8% of the total population. The Sabians (Mandaeans) ethnic group showed the same distribution of ABO and Rh blood groups with others ethnic groups in Iraqi population

Biochemical Evaluation of some Natural Feed Additives against Dexamethasone-induced Metabolic Alterations in Rabbits

Glucocorticoid therapy is limited by numerous metabolic adverse effects associated with long term exposure to excess doses. Therefore, the present study aims to determine the possible protective effects of date palm and/or Saccharomyces cerevisiae probiotics on dexamethasone-induced metabolic changes in rabbits. 25 healthy male white New Zealand rabbits were grouped into group 1 (control), group 2 (2 mg/kg bw/day dexamethasone I/M), group 3 (0.5 g/kg/day date palm flesh+2 mg/kg bw/day dexamethasone I/M), group 4 (1g/kg/day S. cerevisiae probiotic + 2 mg/kg bw/day dexamethasone I/M), group 5 (date palm flesh + S. cerevisiae probiotic + dexamethasone at the aforementioned doses). Dexamethasone injection resulted in marked increases (p≤0.05) in hepatic MDA concentration and catalase activity, as well as significant decreases in hepatic GSH concentration and body weight gain. The serum levels of glucose, lipid profile (TG, cholesterol, VLDL, LDL/HDL risk ratio), and liver function biomarkers (serum total proteins, albumin, ALT, ALP) showed significant variations (P≤0.05) between control and dexamethasone treated group. The ameliorative effect of date palm fruit and/or probiotics (S. cerevisiae) was markedly indicated by restoration of these tested parameters to near normalcy. Therefore, the co-treatment with date or S. cerevisiae could be considered of great interest as potential feed additives for reduction of the adverse metabolic effects induced by dexamethasone in rabbits

Impact Of Breast Feeding Versus Formula Feeding On Surgical Wound Healing In Infants During The First Three Months Of Age

Breast milk has antimicrobial and healing properties that actually can help the wound healing. Surgical infants are at a much higher risk for malnutrition as a result of increased metabolic demands from surgery, nutrient losses, and sepsis. Many methods of feeding are used postoperatively for infants; oral feeding (breast or formula milk), enteral, or parenteral feeding. Aim of this work was to assess the effect of breast-feeding versus formula feeding on surgical wound healing in infant during the first three months. Methods and materials: Comparative descriptive research design was used to carry out this study. It comprised 100 infants aged less than 3 months, they were divided into two equal groups as the following: Group 1: received breast milk feeding, Group 2: received formula milk feeding. Tools were developed by the researcher, after that the researcher fulfill assessment sheet and took anthropometric measurements for each infant then the photographs were taken by the researcher on the 7th postoperative day and reassessed for second time on the 14th day. Results: Out of the included breast-fed infants, 78 % were boys, while 22% were girls

Povidone-iodine versus normal saline solution in preoperative vaginal cleansing before office hysteroscopy: a randomized controlled trial

Background: Hysteroscopy is well-thought-out the gold standard for assessing the uterine cavity, and now can be done as an office process due to enhanced endoscopic advances with no need to in-patient admission. Objective of the present study was to compare the difference in the rate of postoperative vaginal irritation symptoms and postoperative infections after using povidone iodine (PI) and normal saline (NS) solution in vaginal cleaning before outpatient office hysteroscopy (OH).Methods: Women attended to the hospital for diagnostic OH were included for present study. Eligible women were randomly allocated in a 1:1 ratio to two groups. Group I "PI group" women exposed to PI for vaginal cleansing before hysteroscopy, and group II "NS group” women exposed to the NS solution for vaginal cleansing. The primary outcome of the study was to compare the difference in the rate of postoperative vaginal irritation symptoms and postoperative infections in both groups.Results: The mean age of the study participants was 34.26±4.14 years for NS group compared to 35.22±4.01 years for PI group (p=0.652). The PI group reported higher rate of vaginal irritation than NS group with no statistically significant difference between the two groups (p=0.179). Both groups were similar in postoperative fever, urinary tract infection and vaginitis (p>0.05).Conclusions: This study concluded that preoperative vaginal disinfection at the time of OH with a NS solution is less frequently causing postoperative vaginal irritation symptoms. Additionally, it is as effective as the usual agent (PI) in preventing postoperative infections

Study on the Discrimination of Possible Error Sources That Might Affect the Quality of Volatile Organic Compounds Signature in Dairy Cattle Using an Electronic Nose

Electronic nose devices (EN) have been developed for detecting volatile organic compounds (VOCs). This study aimed to assess the ability of the MENT-EGAS prototype-based EN to respond to direct sampling and to evaluate the influence of possible error sources that might affect the quality of VOC signatures. This study was performed on a dairy farm using 11 (n = 11) multiparous Holstein-Friesian cows. The cows were divided into two groups housed in two different barns: group I included six lactating cows fed with a lactating diet (LD), and group II included 5 non-lactating late pregnant cows fed with a far-off diet (FD). Each group was offered 250 g of their respective diet; 10 min later, exhalated breath was collected for VOC determination. After this sampling, 4 cows from each group were offered 250 g of pellet concentrates. Ten minutes later, the exhalated breath was collected once more. VOCs were also measured directly from the feed's headspace, as well as from the environmental backgrounds of each. Principal component analyses (PCA) were performed and revealed clear discrimination between the two different environmental backgrounds, the two different feed headspaces, the exhalated breath of groups I and II cows, and the exhalated breath within the same group of cows before and after the feed intake. Based on these findings, we concluded that the MENT-EGAS prototype can recognize several error sources with accuracy, providing a novel EN technology that could be used in the future in precision livestock farming
