The main objective of this study was to evaluate the adsorption efficiency of two adsorbent materials, Iraqi chicken eggshells (ESh) and activated carbon (AC) derived from ESh powder for the removal of a cationic dye (Janus green B; JGD) from aqueous solution. Activated carbon was synthesised from ESh using a simple chemical activation method using phosphoric acid as the activating agent. The physicochemical properties of the adsorbents were characterised by the Brunauer–Emmett–Teller (BET) method, FT-IR spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), inductively coupled plasma optical emission spectroscopy (ICP-OES), and point of zero charge (pHpzc). The results of BET analysis confirmed th

The argumentative elements ,the author is trying to convey to the reader, are linguistic procedures aim at persuading and being persuaded of what is true. The present study traces, through Camus’ novel The plague, the best method to construct argumentative techniques used to express the author’s deep philosophies.
Résumé
L’argumentation n’est pas un phénomène intellectuel nouveau, ses origines reviennent aux savants grecs et romains. Elle est une act
... Show MoreThis research dealt with the subject of negotiation skills of employees in public relations departments which is one of many skills supposed to be available to these employees. These skills combined help in the success of the job of public relations departments; and give them an important and vital role within the roles distributed in the departments of any government institution wither is governmental or non-governmental.
Negotiation is a skill that requires intelligence, tact, culture, information, intuition, and knowing to use the means of communication to access the information that is useful in reaching satisfactory results
... Show MoreThe agricultural lands that depend on supplementary irrigation methods for winter wheat cultivating in wide areas of the Nineveh province are most vulnerable to climate change concerns. Due to frequent rainfall shortages and the temperature increase recently noticed and predicted by the climate scenarios. Hence important to assess the climate effect on the crop response in terms of water consumption during the periods (2021-2040) and (2041-2060) by using high-resolution data extracted from 6 global climate data GCMs under SSP5-8.5 fossil fuel emission scenarios in changing and fixed CO2 concentration. And validate the Aqua-Crop model to estimate the yield and water productivity. And gives the RRSME of 7.1- 4.1
... Show MoreIn this study, from a total of 856 mastitis cases in lactating ewes, only 34 Streptococcus agalactiae isolates showed various types of resistance to three types of antibiotics (Penicillin, Erythromycin and Tetracycline). St. agalactiae isolates were identified according to the standard methods, including a new suggested technique called specific Chromogenic agar. It was found that antibiotic bacterial resistance was clearly identified by using MIC-microplate assay (dilution method). Also, by real-time PCR technique, it was determined that there were three antibiotics genes resistance ( pbp2b, tetO and mefA ). The high percentage of isolate carried of a single gene which was the Tetracycline (20.59%) followed by percentage Penicillin was

Show More(Received 21 May 2019, Revised 30 September 2019, Accepted 21 October 2019)ABSTRACT : The results of the current study showed that the liver of H. javanicus appeared as large lobulated organ dividedinto six distinct lobes, that filled the cranial region and little extended to the middle region of abdominal cavity. On the otherhand, liver of S. carolinensis laid against the diaphragm, occupied the cranial region of the abdominal cavity and consisted of fivelobes. The liver is surrounded with a thin capsule of dense regular collagenous connective tissue and few numbers of smoothmuscles fibers can be seen in the capsule that covered the squirrel liver. The liver parenchyma divided into a large number ofinterconnected hepatic lobules marked
... Show MoreBackground: The prolonged retention of progesterone-infused intravaginal sponges in estrous synchronization protocols, results in alteration of vaginal microflora, disturbance of vaginal pH, and increased vaginitis in goats. These changes lead to the growth of opportunistic pathogenic bacteria, such as Escherichia coli and Staphylococcus aureus, which need antibiotics to treat this condition. Probiotics have recently been suggested as an alternative method for the maintenance of vaginal health and improving animal fertility. Aim: To investigate the effects of probiotics (Lactobacillus plantarum and L. acidophilus), in compared with enrofloxacin and a control group, on vaginal microflora, vaginal pH, vaginitis incidence, and fertility in

Methods: In a single-center prospective observational study, 74 women with hormone-receptor-positive (HR+)/ human epidermal growth receptor-2 (HER2)-negative metastatic breast cancer were recruited from the Oncology Hospital, Medical City in Baghdad, Iraq. The patients were treated with oral Palbociclib (125 mg) for 21 days, then continued with Letrozole (2.5 mg) for 7 days, and completed six treatment cycles. The candidates were divided into two groups based on therapeutic response: Group 1 responded to the palbociclib plus letrozole combination therapy, a
