In conclusion, prickly pear pulp, skin and whole fruit juice can be used successful for producing jam content bioactive compounds and antioxidant activity with acceptable sensory characteristics.
INTANGIBLE ASSETS INVESTMENT AND FIRMS’ PERFORMANCE: EVIDENCE FROM SMALL AND MEDIUM-SIZED ENTERPRISES IN KOREA

While many studies have examined the relationship between investment in intangibles assets and performance in large corporations, current research is lacking in regard to intangible investments in small and medium enterprises (SMEs). This study looks at SMEs in which intangible investments would usually be minor because they tend to consider intangible investment as an inefficient cost and concentrate on investments in tangible assets. This paper aims to contribute to the current literature and suggests that investment in the intangible assets of (human capital, advertising, R&D) is essential for SMEs pursuing superior firm performance. Actual data collected from 173 SMEs in Korea were analyzed employing hierarchical regression methodology. Results indicate that all three intangible resources have a positive effect on a firm’s profitability and value. Interestingly, this research finds that investment in advertising has the most influential impact on a firm’s profitability and value. This study has implications for SMEs in achieving their profitability and value. The results in this study highlight that intangible investment is not a waste of money for SMEs, and that business managers could strategically utilize these three key contributors (human capital, advertising, R&D) and adopt investment in intangible assets to accomplish their managerial goals.
Resource allocation for energy efficient user association in user-centric ultra-dense networks integrating NOMA and beamforming

A coupling of wireless access via non-orthogonal multiple access and wireless backhaul via beamforming is a promising way for downlink user-centric ultra-dense networks (UDNs) to improve system performance. However, ultra-dense deployment of radio access points in macrocell and user-centric view of network design in UDNs raise important concerns about resource allocation and user association, among which notably is energy efficiency (EE) balance. To overcome this challenge, we develop a framework to investigate the resource allocation problem for energy efficient user association in such a scenario. The joint optimization framework aiming at the system EE maximization is formulated as a large-scale non-convex mixed-integer nonlinear programming problem, which is NP-hard to solve directly with lower complexity. Alternatively, taking advantages of sum-of-ratios decoupling and successive convex approximation methods, we transform the original problem into a series of convex optimization subproblems. Then we solve each subproblem through Lagrangian dual decomposition, and design an iterative algorithm in a distributed way that realizes the joint optimization of power allocation, sub-channel assignment, and user association simultaneously. Simulation results demonstrate the effectiveness and practicality of our proposed framework, which achieves the rapid convergence speed and ensures a beneficial improvement of system-wide EE.
Optimal spatial layout of low-impact development practices based on SUSTAIN and NSGA-II

The optimal spatial layout of low-impact development (LID) practices is the foundation and core of sponge city construction. Suitable LID facilities are selected in accordance with evaluation indices, such as runoff control, ecological benefit, stability, and cost. In this work, a system for urban stormwater treatment and analysis integration model is designed using a geographic information system. This model is solved using the non-dominated sorting genetic algorithm II to obtain a cost-effectiveness curve and an optimal spatial layout scheme. Results show that the reduction rates of rainwater runoff from LID facilities are 95% and 91% in the southern and northern watersheds, respectively, of the Huaiyuan campus of Ningxia University, Yinchuan, China. The construction costs are US$ 2.8 million and US$ 10.9 million in the southern and northern watersheds, respectively. This study is significant for reducing the risk of urban waterlogging, constructing urban ecological security patterns, and optimally allocating LID facilities.
The Challenge of Evaluating Virtual Communities of Practice: A Systematic Mapping Study

Aim/Purpose: This paper presents a study of Virtual Communities of Practice (VCoP) evaluation methods that aims to identify their current status and impact on knowledge sharing. The purposes of the study are as follows: (i) to identify trends and research gaps in VCoP evaluation methods; and, (ii) to assist researchers to position new research activities in this domain. Background: VCoP have become a popular knowledge sharing mechanism for both individuals and organizations. Their evaluation process is complex; however, it is recognized as an essential means to provide evidences of community effectiveness. Moreover, VCoP have introduced additional features to face to face Communities of Practice (CoP) that need to be taken into account in evaluation processes, such as geographical dispersion. The fact that VCoP rely on Information and Communication Technologies (ICT) to execute their practices as well as storing artifacts virtually makes more consistent data analysis possible; thus, the evaluation process can apply automatic data gathering and analysis. Methodology: A systematic mapping study, based on five research questions, was carried out in order to analyze existing studies about VCoP evaluation methods and frameworks. The mapping included searching five research databases resulting in the selection of 1,417 papers over which a formal analysis process was applied. This process led to the preliminary selection of 39 primary studies for complete reading. After reading them, we select 28 relevant primary studies from which data was extracted and synthesized to answer the proposed research questions. Contribution: The authors of the primary studies analyzed along this systematic mapping propose a set of methods and strategies for evaluating VCoP, such as frameworks, processes and maturity models. Our main contribution is the identification of some research gaps present in the body of studies, in order to stimulate projects that can improve VCoP evaluation methods and support its important role in social learning. Findings: The systematic mapping led to the conclusion that most of the approaches for VCoP evaluation do not consider the combination of data structured and unstructured metrics. In addition, there is a lack of guidelines to support community operators’ actions based on evaluation metrics.

Reverse dipper pattern of blood pressure as an indicator of sympathetic over activity in patients with systemic sclerosis and its relation with serum asymmetric dimethylarginine (ADMA) level

Systemic sclerosis (SSc) is a multisystem disorder characterized by extensive vascular damage, with early generalized microangiopathy and fibrosis of the skin and internal organs. SSc is characterized by parasympathetic impairment and marked sympathetic over activity. The aim of this study was to investigate the potential relationship between serum asymmetric dimethylarginine (ADMA) levels and blood pressure pattern with sympathetic over activity in patients with SSc. Thirty patients with systemic sclerosis and thirty controls who had no cardiovascular risk factors were included in this study. All patients and the controls underwent a 24-hour holter recording and their plasma ADMA levels were measured. A total of 10 patients had dipper status (33.3%), 16 patients had non-dipper status (53.3%), 2 patients had reverse dipper status (6.7%) and 2 patients had extreme dipper status (6.7%). ADMA levels were higher in SSc patients when compared with control group and especially significantly higher in SSc patients with reverse dipper status. The relationship between elevated ADMA serum levels and reverse dipper blood pressure patterns in patients with SSC may be the result of sympathetic over activity.

The Serum vitamin D deficiency and vitamin D receptor gene polymorphism as risk factors for hepatitis C virus related hepatocellular carcinoma: a case control study

Background: Hepatocellular carcinoma (HCC) is the most frequent primary cancer of the liver. In Egypt, there is a doubling in the incidence rate in the past 10 years. The screening of HCC still relies on the serum alpha-fetoprotein (AFP) level, which is ineffective in detecting small tumors. Therefore, novel and reliable diagnostic biomarkers associated with increased risk of HCC would better define high-risk populations, helping to improve prevention and treatment strategies. Vitamin D is a steroid hormone implicated in inhibition of carcinogenesis. Genetic variations in the vitamin D receptor (VDR) gene have been reported to associate with increased risk of cancers. The aim of this study is to evaluate the role of serum vitamin D level and VDR polymorphism as predictors of HCC risk in the Egyptian hepatitis C virus (HCV) patients. Methods: Venous blood samples were collected from 60 patients and 30 healthy subjects Patients were categorized into 2 groups: 30 patients with HCV-related HCC, and 30 patients with HCV-related cirrhosis without HCC. Serum levels of AFP and 25-OH D3 were measured using enzyme-linked immunosorbent assay (ELISA). DNA was extracted from whole blood and genotyping for VDR rs2228570 gene polymorphism was done using real time PCR, TaqMan assay. Results: The mean serum vitamin D levels in HCC patients, cirrhotic patients, and control subjects were 15±7.78, 24.24±9.17 and 28.34±12.18 ng/ml, respectively. There was a significant decrease in the mean serum vitamin D level in HCC patients compared to cirrhotic patients (p=0.001) and Roushdy, Abdel Aal, Abdelrahman et al. Senses Sci 2019; 3: 847-863 control subjects (p<0.001). Also, low serum vitamin D level was significantly correlated with advanced cancer stage (p<0.001). In HCC patients, the frequencies of VDR rs2228570 AA, AG and GG genotypes were 6.7%, 40% and 53.3% respectively. There was significant association of the VDR rs2228570 GG genotype with HCC cases (OR=3.14, P=0.035) when compared with controls. Conclusion: Low serum vitamin D level and VDR rs2228570 polymorphism may contribute to increased susceptibility to HCV-related HCC.
Factors associated with belief or disbelief in false news: From the perspective of elaboration likelihood and moderating effect model

Based on the elaboration likelihood model, this study examines the impact of central and peripheral cues to determine the relative influence of each cue on user’s belief or disbelief in false news, and to investigate whether information literacy acts as a moderator to the cues. Results indicate that argument quality influences users to recognize the falsehood of messages delivered by either social media groups or news website groups. The impact of peripheral cues on social media tends to make users vulnerable to believing in false news (BFN), but not on news websites. Information literacy has no moderating effect on any cues, but has a direct effect on BFN from news website groups but not from social media groups.

The study found out that; use of media during teaching and learning assists teachers in realizing lesson objectives, CRE concepts are well understood when teachers use media in teaching. The study also revealed that students preferred electronic media as compared to textbooks and chalk walls. The study recommends that; head teachers should provide adequate electronic media in schools to enhance the teaching and learning of CRE.
Coatings on Metals and Plastics for Lunar Habitats and Equipment

The lunar surface is a harsh environment for future habitats and equipment. Lunar nighttime survival, in particular, will pose a considerable engineering challenge. Coatings applied on various substrate materials will be one of the key technologies for thermal engineers. Although many known coatings can provide desirable thermo–optical properties in a lab environment, the use of such coatings on the lunar surface will be complicated in many cases. For example, lunar dust particles can become electrically charged, and the adherence of such particles to coated surfaces must be minimised. The extreme range of surface temperatures on the Moon leads the thermal engineer to prefer coatings with a very low emissivity factor. Such coatings are highly sensitive to the accumulation of dust. Technologies such as atomic layer deposition (ALD) and indium tin oxide (ITO) coatings show promise as coating of metals and plastics, resulting in lower mass for the overall thermal system.
FIRMS PRACTICE AND INNOVATION MANAGEMENT: CASE OF FUJAIRAH EMIRATE, UNITED ARAB EMIRATES

Innovation Management has received a lot of attention in the last few decades, from a vital determinant of the global competitiveness of nations over the coming decade to the primary driver of economic progress and well-being. Many countries over the world have adopted national strategic roadmaps to foster innovation and enhance its economic impact to boost productivity and growth. The United Arab Emirates (UAE) came forward with the launch of the National Innovation Strategy in 2014. Hence, this paper has investigated the strategic importance of innovation management as a need for change and firms practices in one of the UAE Emirates (Fujairah Emirate). In doing so, the paper has sought to understand whether the concept of innovation management is featured in the UAE Company’s culture and strategic plans or whether the management of the business firm is highly committed to innovation management and what an essential driver for UAE to engage in innovation management. To investigate this problem, a qualitative case study methodology is used to collect and analyze the data. Results indicate that there is a clear line of innovation management strategies in UAE and business firms in Fujairah Emirates response to concerns by integrating innovation management into business structure and systems.
RESPONSE OF LACTATING BUFFALOES TO FIBROLYTIC ENZYMES AND THEIR INFLUENCE ON MILK AND CHEESE PROPERTIES

he task of this research is assessing the action of two different fibrolytic enzymes supplementation on milk yield and cheese properties by lactating buffaloes. Three sets had been worked on, everyone had three animals of lactating buffaloes after 3 months of parturition, with 30 days interval. The first one was fed on 50% concentrate feed mixture (CFM), 30% corn silage, 20% rice straw served as control (C). The second and third sets were fed on the same control ration supplemented with Asperozym or Tomoko at 2 g kg DM served as (T1 and T2). These three different types of lactating milk had been used to manufacture of white soft cheese (WSC). Both of milk and WSC samples were analyzed for some chemical parameters (milk & cheese yield, pH, total solids, total protein, ash contents, free fatty acids and amino acids profile). Furthermore, sensory evaluation of WSC samples had been taken in consideration. Data revealed that supplementation with Asperozym or Tomoko enzymes had significantly (P<0.05) increased 4% fat-corrected milk and cheese yield. On the other hand, WSC samples with both of fibrolytic enzymes were significantly (P< 0.05) rose in short and long chain fatty acids, while Asperozym cheese samples only were lower in medium chain fatty acids compared to control. Regarding to other chemical composition parameters (TN, TN/SN, TVFAs, tyrosine, tryptophan and pH values) of resulted cheese during storage period, all these parameters were significantly (P<0.05) boosted after 15 days of storage. For amino acids profile, Asrozym and Tomoko were lowered (P<0.05) histidine, threonine, isoleucine, leucine, glycine, alanine and proline but Tomoko enzyme raised (P<0.05) valine, methionine, phenylalanine and serine. Supplementation of fibrolytic enzymes did not manipulate (P>0.05) sensory evaluation of WSC samples. Supplementation of fibrolytic enzymes on buffalo's diet did not significantly affect lactation performance except 4% fat corrected milk, fatty acids and amino acids profile in WSC. Therefore, further study must be conducted on the impact of fibrolytic enzymes on different lactating animals.
THE ACCURACY OF CONE BEAM COMPUTED TOMOGRAPHY IN ASSESSMENT OF TOOTH AND ROOT LENGTH MEASUREMENTS: IN-VITRO STUDY

Aim: Assessment of the accuracy of cone beam computed tomography in tooth and root length measurements. Methods: 50 human extracted teeth were used in the current study. The 50 premolars were divided into two groups: Group (1) consisted from 25 double rooted maxillary first premolars while Group (2) comprised 25 single rooted mandibular first premolars. Teeth and roots lengths were measured for each group with a manual caliper and from CBCT images. Physical and CBCT measurements were taken twice by two observers and the average values were used to avoid interobserver errors to compare between the manual caliper and the CBCT measurements and then the accuracy of CBCT was assessed. Results: Intraclass correlation between CBCT vs. Physical Measurements ranged from (-0.04 to -0.759) which indicates a complete disagreement between the physical measurements and CBCT measurements for all tested groups. Conclusion: Dental measurements taken on digital models are not as accurate as those taken manually. There is always underestimation of CBCT measurements compared to physical measurements. (470) Omniya Abu El-Dahab and Iman Dakhli E.D. J. Vol. 63, No. 1 for their accuracy. Although the need to ascertain CBCT accuracy is not controversial, its accuracy has not been satisfactorily verified(1-7). Tomogram based morphological measurements are influenced by some factors including identification of bony landmarks and experience of the examiner. Despite the importance of these factors to identify and minimize the measurement errors, it is unachievable because these factors are not separable in real life conditions. Therefore, measurement errors remain the major source of uncertainties in various applications such as the diagnosis, planning, and evaluation of treatment. Moreover, because these morphological measurements may be taken by the same or different clinicians of different experiences, and at different stages in the management of one patient, it is also imperative to determine if the measurements used are reliable both within (intrarater) and between clinicians (interrater), and between sessions (intersession)(8).
