Understanding the commitment efficiency, process and influence of journalism professionalism practices amongst web newspaper journalists in Saudi Arabia / Saleh Zaid S Alenizi

The phenomenon of web journalism in the Kingdom of Saudi Arabia is one of the new practices in Saudi journalism. Despite the newness of this journalistic phenomenon, a number of Saudi web newspapers (more than 250 web newspapers according to a mini¬survey conducted to determine the number of Saudi web newspapers) differs in terms of their ideological and professional orientations. There are web newspapers that cover specific regions in Saudi Arabia, web newspapers specializing in a given topic such as sports, children, women, business web newspapers, as well as general web newspapers that cover various topics

Separation and concentration of health compounds by membrane filtration

The performance of nano-filtration (NF) for separating phenolic compounds from sugar in apple juice was studied using 1 and 0.25 kDa molecular weight cut-off (MWCO) spiral wound membranes. If these phenolic compounds could be recovered, they could stabilize the juice from haze formation or be added as antioxidants to foods and beverages in order to increase their health properties. Batch experiments were conducted on a pilot scale rig using a diluted clear apple juice concentrate. For the 1 kDa MWCO membrane, the research determined the effect of operating conditions on process efficiency and membrane fouling. The concentration of polyphenolics on the retentate side increased by a factor of up to 4 and the sugar concentration increased by 1.5 times under optimum conditions of lower temperature (30oC), acidic pH (2), lower transmembrane pressure (5 Bar) and higher initial sugar concentration (20 oBrix). Despite the increase in polyphenolics in the retentate, there was little difference in the phenolic composition between retentate and permeate solutions. As the molecular mass of the rejected phenolics was smaller than the membrane cut-off, this indicated that the rejection was related to the formation of a secondary membrane formed as a result of fouling. A mass balance of polyphenolics in the final retentate and permeate compared with the initial feed solution indicated that up to 4.3 gm of polyphenolics were bound per m2 of membrane. The permeate solutions collected from the 1 kDa MWCO membrane were then filtered using a 0.25 kDa MWCO membrane. Most phenolic compounds were retained by the membrane and the concentration increased by a factor of up to 2. Catechin, rutin, phloridzin and quercetin derivatives were concentrated on the retentate side. However, around 20-40% of chlorogenic acid and epicatechin was observed on the permeate side. It is concluded that membrane separation represents a potentially efficient and cost-effective technology to separate the phenolic fraction of fruit juice in a form suitable for use as a functional ingredient

Fouling Characteristics of a Light Australian Crude Oil

Australian crude oils, which generally contain little asphaltenes, nevertheless give rise to fouling in refinery pre-heat trains. In this research, fouling of a series of such crude oils and their blends is being assessed. The present work focuses on thermal fouling resulting from heating Gippsland crude oil at moderate temperatures. The oil is maintained under nitrogen at a pressure of 379 kPa, and re-circulated at bulk temperatures of 80-120°C through an electrically heated annular probe at velocities in the range 0.25 to 0.65 m/s with surface temperatures from 180-260°C. Experiments are run for periods up to 90 hours at constant heat flux. Fouling is detected by the increase of wall temperature of the probe. The oil is characterized by its filterable solids content, density and viscosity both before and after the fouling run. The trends in fouling rates are compared to predictions of the threshold-fouling model proposed by Ebert and Panchal (1995). Data on deposit composition are presented, and the fouling mechanism discussed

The influence of audit committee characteristics on modified audit opinion in Jordan

The Jordanian Corporate Governance Code (JCGC) was first enacted in 2004 and revised in 2017. It offers standards for ethical and decent practices in the corporates. Law in Jordan in 2009 has enforced the formation of an audit committee for all listed companies. Literature has substantiated that the audit committee characteristic (ACCs) impact the quality of financial reporting. This work investigates the role of ACCs in lessening the prospect of corporates in obtaining modified audit opinion in the context of Jordan. Four ACC problems (expertise, independent, meeting, and size) have been studied and the modified audit opinion. The total sample of 117 listed companies on the Amman Stock Exchange (ASE) was studied. The relationship between the modified audit opinions (dependent variable), and ACCs (expertise, independent, meeting, and size; as independent variables) was analyzed using logistic regression. The ACCs is projected to effectively improve the quality of financial reporting, and thus, decrease the prospect of corporate in obtaining modified audit opinion. The findings according to the listed companies from 2012 to 2017 in Jordan showed that audit committee (AC) expertise validates this likelihood. Lastly, there is no effect of AC independent, size, and the number of meetings held on the modified audit opinion. General, the findings have policy implications on enhancing corporate governance (CG) efficacy concerning the quality of financial reporting

The Effect of Religious Monuments in the Plan of the ArabianIslamic city Samarra City – Case Study

Religious monument is considered as one of the most distinguished elements which form one of the components of architectural structure, religious monument’s importance stands out from the religious affiliationof the city’s people (Spiritual affiliation). Also considered one of the distinguished architectural elements and recognized architectural identity, which have drawn the mental image for the formation of religious cities in people’s memory. The research depends on studying the plans of the religious cities specifically the Arabian Islamic cities; for its religious importance and the clearness of the religious factor’s impact in its creation and planning, and from reviewing the previous studies those dealt with analyzing the Arabian Islamic city the research problem had been determined in “There is a knowledge gap about the role of religious monuments in planning of the Arabic Islamic cities”,the research hypothesis have been formulated as The religious monument has a regulatory role in planning the Arabian Islamic city, in its impact on axial connection on both local stage and global level. The research has defined the religious monuments as landmarks or architectural elements of the city’s plan which differentiate in attendant appearance in people’s memory, which is generally showing in worship places, from all that the research’s target has been determined as: Clarifying religious monuments' role in Planning of Arab Islamic cities according to the impact that it have played as a regulatory element for the urban fabric. Samarra have been chosen for the required practical study, considering it’s one of the most important Arab Islamic cities, for what it has of religious monuments, which perform as regulatory power for the local and global connection, research confirms from experience research’s letter using (GIS: ArcView 3.3) computer software for the chosen urban formation that: the impact of the religious factor reflects on the components of the urban fabric of the Arabian Islamic city from both of the form and the space in its planning and regulation, which shows on the group of planning elements for the city, also the religious monuments have an effect on the orientation of spatial connection, and creating public areas in the city, and preparingcomplete spaces which have a high permeability around its locations, As well asits effect on the most complete distribution type in other parts of the syste

ORAL CANDIDA ALBICANS COLONIZATION RATE IN FIXED ORTHODONTICS PATIENTS

Objectives:  The objective of this study was to assess the oral Candida albicans colonization ( OCAC)  in a cluster of teenagers and young adults while being treated with a fixed orthodontic appliance (FOA). Subjects and methods:  The investigational group was selected from orthodontic patients whom were examined clinically as soon as to get baseline information before active treatment.  The cluster included 210 patients; 45 males, 165 females (mean age 21.6 ± 4.5 years).  Clinical, demographic data and risk factors were collected in standard questionnaire then each individual was directed to carry out oral wash by a phosphate-buffered saline solution, which was expectorated and processed intended for the isolation of Candida species on Sabouraud’s dextrose agar. The isolated Candida species were identifying by culturing on chromogenic Candida agar and notice species-specific colony natures. Results:  The predominant Candida species isolated was C. albicans with OCAC rate equal to 13.8% extensively enhanced after the insertion of a FOA, as revealed by the oral rinse (P < 0.05) techniques. The results also revealed an increase of OCAC in male patients (24.4%) than female patients (10.9%),   21-25 years patients (17.1%), and regular smoking and Qat chewing were significant associated risk factors (OR=28.6, OR=10.7 respectively , P < 0.0001).  There was no significant association between C. albicans  colonization with oral hygiene in fixed Orthodontic patients. Conclusion:  As a whole, the current data suggest that the introduction of FOA is likely to promote OCAC. Moreover, it becomes visible that the routine oral hygiene procedures performed by these patients may not necessarily reduce OCAC while smoking and chewing Qat habits significantly increased OCAC in FOA. Also smoking and Qat chewing during FOA treatment should be banned if potential harmful effects are to be prevented. Further work with a larger sample size is required to confirm or deny these results.                      Peer Review History: Received 27 March 2020; Revised 20 April; Accepted 8 May, Available online 15 May 2020 Academic Editor: Ahmad Najib, Universitas Muslim Indonesia, Makassar, Indonesia, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

The effect of alpha-lipoic acid supplementation on anthropometric, glycemic, lipid, oxidative stress, and hormonal parameters in individuals with polycystic ovary syndrome: a systematic review and meta-analysis of randomized clinical trials

This systematic review and meta-analysis aimed to examine the effect of the antioxidant alpha-lipoic acid (ALA) on various cardiometabolic risk factors and hormonal parameters in patients with polycystic ovary syndrome (PCOS). We searched PubMed, EMBASE, SCOPUS, Cochrane Library, and Web of Science databases without language restrictions until May 2023 to find randomized controlled trials (RCTs) that assessed the impact of ALA supplementation on anthropometric, glycemic, lipid, oxidative stress, and hormonal parameters in women with PCOS. Outcomes were summarized using the standardized mean difference (SMD) and 95% confidence interval (CI) in a random-effects model. An I2 statistic of >60% established significant between-study heterogeneity. The overall certainty of the evidence for each outcome was determined using the grading of recommendations, assessment, development, and evaluations system. Seven RCTs met the inclusion criteria. The ALA group had significant reductions in fasting blood sugar (fasting blood sugar (FBS), n=7 RCTs, SMD, −0.60; 95% CI, −1.10 to −0.10; I2=63.54%, moderate certainty of evidence) and homeostatic model assessment for insulin resistance (homeostatic model assessment of insulin resistance (HOMA-IR), n=4 RCTs, SMD, −2.03; 95% CI, −3.85 to −0.20; I2=96.32%, low certainty of evidence) compared with the control group. However, significant differences were observed between the groups in body mass index, insulin, estrogen, follicle-stimulating hormone, luteinizing hormone, testosterone, low-density lipoprotein, high-density lipoprotein, triglyceride, total cholesterol, malondialdehyde, or total antioxidant capacity profiles. ALA supplementation improves FBS and HOMA-IR levels in women with PCOS. ALA consumption is an effective complementary therapy for the management of women with PCOS
