The Relation between Postulations of Behavioral and Traditional Economics with Reference to Islamic Economics
Authors: Al-Afandi Prof. Dr. Mohammed Ahmed
Published: July 2022

The study examines the main postulations of behavioral economics, which is based on the integration of psychological and neurological determinants in economics, in order to provide a better understanding of individuals' economic behaviors. These postulations attempt to make economics a human discipline, where there is a reference to the falsity of the postulations which say that economics is a neutral science and that it should be separated from ethics. The study focused on analyzing the nature of the link and relationship between behavioral economics and contemporary (traditional) economics, which represents a new branch of contemporary economics; but it is not a substitute for it. The study also assessed the level of similarity between behavioral economics and the method of analysis in Islamic economics. The study adopted the descriptive and analytical method. The findings revealed that there is a new bridge of communication between contemporary economics and Islamic economics, where the behavioral economics had a role in its construction. In many cases, this may seem to be one of the rules of economic behavior of individuals and the society.

Keywords: behavioral economics, postulations of behavioral economics, contemporary (traditional) economics, stimulation and motivation, individuals' economic rules.

Published: July 2022

This study aimed to identify the effect of customer capital (including its dimensions:  customer acquisition, allocation, market share, customer satisfaction, and customer loyalty) on achieving a competitive advantage in the banking sector in Yemen (including its dimensions: cost reduction, innovation excellence and flexibility). The study used the descriptive analytical method on a sample of 86 participants selected purposively from the study population, which was (380) members, covering directors, managers, heads of departments and workers in Yemeni banks in the governorate of Taiz. Using the SPSS package, the descriptive and inferential statistical methods were used to analyze data. Major findings revealed there was a direct impact relationship between the customer capital and the competitive advantage in the banking sector, where the customer satisfaction dimension was found to be the largest contributor to achieving competitive advantage. Furthermore, findings showed that there was a lack of training offered to workers on customer acquisition skills (as it is an important variable in acquiring customers). There was also a disparity between Yemeni banks in having databases to track customer preferences and keep them for use whenever the need arises. The study concluded that banks need to enhance their employees' skills of customer acquisition, and to develop a marketing system to track customer preferences which are imperative to achieve the competitive advantage.

Educational Concepts and Implications Derived from Surah Al Qasas: An Analytical Study
Authors: Dr. Hamid Saif Qassem Thabet Alqadri
Published: July 2022

This study aimed to highlight the status of Surah Al Qasas among other Surahs of the Holy Qur'an as well as to investigate significant educational principles, values and styles included in the Surah. The researcher used the descriptive method based on analysis and deduction. The study findings revealed that Surah Al Qasas is one of the Meccan Surahs of Qur’an, whose main goal is to show the true balance of power and values represented in the power of God, and the value of belief in Him. The findings also showed that the Surah includes a number of educational principles, values, styles and meanings, which should be derived and applied in education. Based on these concepts and principles, the educational theory in the Muslim community should be developed. The reason behind the imbalance in the value and ethical system of today's Muslim community is attributed to the absence or lack of incorporation of such values deduced from   Surah Al Qasas into the curricula and institutions of Islamic Education. In light of these results, the study recommends the need for integration of and interaction between Islamic educational institutions, particularly the family, the mosque and the school, in activating and applying educational concepts and implications deduced from Surah Al-Qasas. It is also recommended that educational policies in the Muslim community should be re-analyzed and re-developed, taking these educational concepts and implications into consideration.

Keywords: educational styles, Surah Al Qasas, values, educational principles, educational implications.

Authors: د. فاتن هادي الحربي
Published: July 2022

This study investigated the level of life satisfaction and psychological flow among female students at Unaizah College in Saudi Arabia. To achieve this, a measure for life satisfaction was developed and the Arabic version of the psychological flow measure, developed by Marsh and Jackson (1996), was adopted. After verifying the psychometric properties of the two scales, they were administered to a sample of 225 female students (79 married and 146 unmarried). The collected data was processed and analyzed by using the SPSS. The findings revealed that married students had more life satisfaction than unmarried ones, but there were no differences between them regarding the psychological flow. There was also a statistically significant positive correlation between life satisfaction and the psychological flow. Regarding specialization, students of engineering colleges showed more life satisfaction and psychological flow than students of human colleges. The study concluded with a set of recommendations, including encouraging female students to get married while at college.
Honey Value Chain at Al Osaimat District in Ammran Governorate, Yemen
Authors: Dr. Maher Abdulla Moharram
Published: July 2022

Due to its varied ecological and climatic conditions, Yemen has a favorable natural resource endowment for the beekeeping and comparative advantage in the production of honey. Al Osaimat is not an exception where Al Osaimat honey is a well-known brand name inside and outside Yemen. Value chain development is a growing approach used worldwide to increase incomes of small producers and the economically active poor families. This study aimed to investigate the flow of honey production by exploring the status of the value chain and identifying the opportunities and constraints in the chain, where appropriate interventions are possible to minimize the chain risks and maximize value. A sample of 72 beekeeping households was surveyed, and for the deeper understanding of the state of honey chain, two focus group discussions and key informant interview were conducted. The results showed the absence of any official attention to the apiculture in the area and the lack of proper training to the chain actors, the domination of old-fashioned beekeeping practices, and the non-availability of supportive actors particularly the financial institutions. Furthermore, the study summarized the seven most important constraints and recommended intervention(s) for the value chain development.
The Implications of the Levels of Linguistic Analysis in the Hadith of the Victorious Sect
Authors: Assoc. Prof. Dr. Yahya Muhammad Ali Al-Mahdi
Published: July 2022

This study deals with the hadith of the Victorious Sect, which is considered an important principle of loyalty and disavowal in Islam and a testimony of the Prophet Mohammed's (SWS) prophecy. This is a Mutawatir (consecutive) hadith narrated by nearly twenty companions. Using an analytical descriptive method, the present study examines the hadith's words and phrases at different linguistic levels: phonetic, morpho-syntactic, and semantic. Results at the phonetic level show that there is a prevalence of voiced, unaspirated, and explosive sounds that have strong impact on the listener. At the morphosyntacticlevel, results show a prominent presence of the nominal structures that indicate stability and permanence, with some use of verb phrases that indicate renewal, continuity and interactiveness. It seems that the morphosyntactic structures play a great role in determining the semantic interpretations of this hadith with its multiple narrations. This is evident not only through theuse of structures indicating eternal existence and presence across times to confirm meaning and to engrave it in the minds of listeners, but also through the connotations of generalization, specification, focus, emphasis, contrast, and others. All are intertwined in a linguistic harmony in which all linguistic levels - sound, form and structure - perform their function in the fullest and most meaningful way.

The Role of Consumer Satisfaction and Patriotism as Mediating and Moderating Variables in the Relationship between Loyalty to Yemeni Fruits and its Antecedents: A Field Study of a Sample of Yemeni Consumers
Authors: د. ماجد مبخوت جعيل
Published: July 2022

This study aims to examine the effect of consumer satisfaction (as a mediator variable) on the relationship between loyalty to Yemeni fruits and its antecedents represented by awareness, mental image, perceived quality, and trust. Besides, it examines the effect of Yemeni consumer patriotism (as a moderator variable) on the relationship between consumer satisfaction and loyalty to Yemeni fruits. To achieve this, the descriptive analytical method was followed and a questionnaire was used to collect data from a simple random sample of 304 consumers in Sana'a and Thamar. The data were analyzed using the Partial Least Squares (PLS) program. The study revealed that satisfaction fully mediates the relationship between the mental image and perceived quality and loyalty to Yemeni fruits; that is, the mental image and perceived quality indirectly affect loyalty to Yemeni fruits through the satisfaction of Yemeni consumers. In addition, that satisfaction partially mediates the relationship between awareness and trust and loyalty to Yemeni fruits; this means that awareness and trust directly and indirectly affect loyalty to Yemeni fruits through satisfaction. While Yemeni consumers have high patriotism, their satisfaction does not affect loyalty to Yemeni fruits any more compared to consumers with low patriotism. The study recommends developing and enhancing loyalty to national products in general and Yemeni fruits in particular among Yemeni and non-Yemeni consumers, within the limits of the Yemeni market environment or Arab and foreign markets.

Authors: Kwiecien Grzegorz J. , Meaike Jesse , Inwards Carrie Y. , Rhee Peter C.
Published: July 2022

Case:

A 53-year-old man sustained an injury to his left index finger and underwent presumably traumatic neuroma excision from the radial digital nerve 2 years ago. He presented with a painful mass distal to the prior site of neuroma excision with distinctly different symptoms from those that led to his index surgery. Thus, he underwent excisional biopsy of the mass which was adherent to his radial digital nerve consistent with a benign glomus tumor on histologic examination.

Conclusion:

Digital nerve glomus tumors are rare. In most of the cases, some portion of the digital nerve requires excision but decreased pain can be expected.

Estimated impact of temperature conditions on deep pits natural ventilation in the Arctic
Authors:   St. Petersburg Mining University, GENDLER Semyon , BORISOVSKY Ivan ,   St. Petersburg Mining University,
Published: July 2022

The Arctic zone of Russia is a territory where such minerals as gold and other precious metals are concentrated. Most often, the development of such deposits is carried out by an open method. The conditions hindering its use should be considered: the depth of distribution of permafrost and significant amplitude of changes in atmospheric air temperature during the year, month and day. The consequence of the alternation in depth of temperature zones may be the formation of recirculation zones in which harmful substances accumulate. Purpose of work. Study of the formation of velocity and temperature fields in a quarry under natural ventilation, taking into account the complex dynamics of atmospheric air temperature. Research methods. Systematization, generalization and analysis of theoretical and experimental studies in this area, including those carried out at the considered fields. Analysis of the results of mathematical modeling of aerodynamic processes in a quarry. Results. It is noted that to assess the peculiarities of formation of the mine atmosphere parameters it is sufficient to carry out only mathematical modeling of aerodynamic processes allowing to define the conditions of temperature inversions formation and dimensions of recirculation zones being potentially dangerous for accumulation of pollutants. The methodology of aerodynamic processes modeling taking into account the geometry of the pit space, temperature gradient, speed and direction of the wind flow is proposed. It is shown that at positive and negative temperature differences for the two investigated air media the development of recirculation movement zones of air masses that assure the accumulation of pollutants which in turn leads to reduced efficiency of natural ventilation in the pit, is characteristic. The conclusion has been made on the necessity to apply additional engineering measures during the period of inversion formation with negative temperature gradient in order to normalize the pit air parameters.
Oil Recovery by Low-Rate Waterflooding in Low-Permeability Water-Wet Sandstone Cores
Authors: Aslanidis P. , Strand S. , Puntervold T. , Yeboah K. K. , Souayeh I.
Published: July 2022

Smart water or low-salinity (LS) water injection are environmentally friendly methods for efficient hydrocarbon recovery. Wettability alteration toward more water-wet conditions and increased spontaneous imbibition (SI) of water are responsible for enhanced oil production. Wettability alteration and SI to expel oil from the low-permeability matrix are time-dependent processes and both injection rate and oil viscosity are important factors affecting the contribution of capillary and viscous forces to oil production.

Low flooding rate must be applied in laboratory corefloods to allow for SI and improved sweep to take place. Residual oil saturation by waterflooding and SI has previously been determined in low-permeability limestone and in higher permeability sands under various flooding rates, wetting conditions, and initial oil saturations. In this study, the effect of flooding rate on oil displacement from low-permeability, water-wet Bandera Brown outcrop sandstone cores has been examined. Viscous forces have been varied by injection at two different rates in addition to SI experiments and using mineral oils with different oil viscosities.

The results showed small differences in oil recovery by SI and viscous flooding at high and low rates, indicating that capillary forces contribute significantly to the oil mobilization and production process from this low-permeability, water-wet rock. By varying the oil viscosity, the results indicated that capillary forces were especially important for oil displacement at higher oil viscosity as the ultimate oil recovered by low-rate injection was higher than that from the high-rate injection. Capillary number calculations indicated that viscous forces should be dominant in the recovery tests; however, the experiments showed that capillary forces were important for efficient oil displacement from the low-permeability, water-wet cores used in this study. There was no direct link observed between generated pressure drops at high and low injection rates, including SI, and the ultimate oil recovery. Thus, to simulate oil production in the middle of the reservoir, it was concluded that low-rate waterflooding is needed in laboratory tests to allow SI into the matrix to displace oil by positive capillary forces.

The combination of using oils that differ in viscosity at different injection rates could add some additional information to the literature on how to increase the efficiency of waterflooding with a low injection rate.
Inverse Modeling of Reservoirs with Tilted Fluid Contacts

Published: July 2022

In this paper, we present a new approach for simulating reservoirs with tilted fluid contacts produced by hydrodynamics. The proposed method solves a nonlinear inverse problem to determine the aquifer flow field that best reproduces the observed contact tilt. The computational effort required to solve this inverse problem is reduced by choosing a pressure-based objective function and applying gradient-based optimization. This approach is entirely automated, in contrast to previous works that have used laborious trial-and-error methods to estimate the aquifer flow field. In addition, the proposed method introduces no additional physics beyond hydrodynamics to model reservoirs with tilted contacts.

The proposed method is integrated into a parallel reservoir simulator. A synthetic reservoir is constructed by introducing an artificial tilt, and the new approach is applied to estimate the aquifer flow field. The estimate produced by the proposed method matches the true flow field well and is able to prevent large fluid motions near the contact surface when simulating production from the reservoir. The proposed method is compared with an existing approach that uses capillary pressure adjustments to hold the tilted contact in place. The proposed method is shown to outperform the existing approach without significantly impacting the simulation results.

The inhibitory management effect is usually un- derestimated in artificial control systems, using biological anal- ogy. According to our hypothesis, the muscle hypertonus could be effectively compensated via stimulation by bio plausible patterns. We proposed the approach for the compensatory stimulation device in development of previously presented archi- tecture of neurointerface, where (1) neuroport is implemented as DAC and stimulator, (2) neuroterminal – as neurosimulation of a set of oscillator motifs on one-board computer. In the set of experiments with 5 volunteers we measured the efficacy of motor neuron inhibition via antagonist muscle or nerve stim- ulation registering muscle force with and without antagonist stimulation. For the agonist activation, we used both voluntary activity and electrical stimulation. In the case of stimulation of both agonist and antagonist muscles and nerves, we exper- imented with delays between muscles stimulation starts in the range 0...20 ms. We registered the subjective discomfort rate. We didn’t identify a significant difference between antagonist muscle and nerve stimulation in both voluntary and stimulation of agonist activity. We determined the most effective delay between stimulation of agonist and antagonist muscle/nerve as 10–20 ms.

Published: July 2022

Background:Chronic obstructive pulmonary disease (COPD) is a major chronic disease and a common cause of death. Analysis of risk factors of complications in patients with chronic obstructive pulmonary disease death is the most important. Computed tomography (CT) which can be used to measure CT emphysema score and pulmonary artery diameter may be related to the complications of COPD. Methods: We retrospectively studied the correlation between CT emphysema score and pulmonary artery diameter PA in patients with COPD in intensive care unit (ICU).We has selected 145 patients with AECOPD who underwent mechanical ventilation in ICU of our hospital as the data of inpatients in ICU from December 2013 to January 2021. The correlation analysis and logistic regression analysis of multiple indexes of patients were analyzed according to the observation indexes such as survival after 28 days. Results: According to the survival, the current sample size was divided into survival group and non survival group. there are significant differences in CT emphysema Score, PA and PaCO2 between the two groups. The CT emphysema Score and PA were related to 28 day survival,The CT emphysema Score and PA emphysema were 0.605 and 0.507, respectively; It can be considered that the pulmonary artery diameter influence AECOPD is slightly less than the CT emphysema Score. Conclusion: CT emphysema Score and pulmonary artery diameter greater than 34mm is a clinical value of the prognosis of AECOPD patients admitted to ICU by chest CT examination. The worse the emphysema, the worse the prognosis and this outperformed Pulmonary artery diameter.

A factorial design 23 was used to evaluate the influence of temperature, catalyst and time and esterification degree (DE) of pectin obtained from mango, orange and tangerine peels as well as tamarind seeds by using the acid hydrolysis method. The study showed that a high temperature positively influenced the efficiency percentage of pectin yield for the four second generation biomasses. Nevertheless, the temperature showed a greater influence in the solubility and diffusion of the acid solvent in the tamarind seed matrix, getting a pectin recovery 32.9%. To determine the %DE, it was observed that the most statistically significant value depends on the studied biomass. The %DE and the nature of the pectin are determining factors in the pectin’s final use, in the present work the pectin extracted was used to produce furfural, a precursor of high value chemicals. The furfural production was achieved through alkaline hydrolysis and enhanced using the Maillard reaction, reaching a maximum concentration of 71.8 g/L which represents a 42.1% increase from the alkaline hydrolysis.

Published: July 2022

In this study, we investigated the possible relation between the Indian summer monsoon and the combination of the different phases of Pacific Decadal Oscillation (PDO) and El Niño Southern Oscillation (ENSO) before and after the climate shift in 1976. This study is carried out using IMD’s rainfall dataset, HadISST v1.1 dataset and twentieth century reanalysis dataset by comparing anomalies of the respective parameters from 1901 to 2020. It is found that when positive (negative) phases of PDO and El Niño (La Niña) co-occur, deficit (surplus) rainfall are likely to occur over entire India. SST signatures of both phenomena are evident in this context. However, when negative (positive) PDO and El Niño (La Niña) co-occur, the signal is mixed and it is unlikely that either surplus or deficit rainfall conditions will occur over entire India. SST signatures are disrupted and minimised. In other words, when ENSO and PDO are in (out of) phase they enhance (counteract) the conventional monsoon-ENSO relationship. After confirming climate shift in 1976, the study periods were further divided into pre and post climate shift periods based on Niño 3.4 index and PDO index and analysed their impact on the Indian summer monsoon rainfall. In the pre-shift example, in-phase conditions exhibit similar qualities to those described above. Rainfall patterns are more indicative of ENSO than PDO. In the post-shift situation, the positive anomaly of SST in the PDO and Niño region is significantly stronger than in the pre-shift phase. When compared to the pre-shift example, positive rainfall anomalies are amplified during positive PDO and El Niño, while negative PDO and La Niña show a weakening of positive rainfall anomalies. The out-of-phase condition has a balancing effect due to the counteracting impact, but with an increased positive anomaly of SST. In that combination, rainfall patterns with PDO characteristics rather than ENSO characteristics emerge. Low level wind anomalies and other circulation features are consistent with the above result.
Viticulture extension in response to global climate change drivers - lessons from the past and future projections

The potential areal extent of agricultural crops is sensitive to climate change and its underlying drivers. To distinguish between the drivers of past variations in the Mediterranean viticulture since Early Antiquity and improve projections for the future, we propose an original attribution method based on an emulation of coupled climate and ecosystem models. The emulator connects the potential productivity of grapevines to global climate drivers, notably orbital parameters, solar and volcanic activities, demography and greenhouse gas concentrations. We found that variations in potential area for viticulture during the last three millennia in the Mediterranean Basin were mainly due to volcanic activity, while the effect of solar activity and orbital changes were negligible. In the future, as expected, the dominating factor is the increase in greenhouse gases, causing significantly drier conditions and thus major difficulties for viticulture in Spain and North Africa. These constraints will concern significant areas of the Southern Mediterranean Basin when global warming exceeds +2°C above pre-industrial conditions. Our experiments showed that even an intense volcanic activity comparable to that of the Samalas - sometimes considered as the starting point of the Little Ice Age at the mid 13th century - would not slow down this decline in viticulture yield in the southern margin of the Mediterranean area.

Background: Our aim was to explore the risk factors for chronic pain and related miRNA phenotypes in patients with lung adenocarcinoma after video-assisted thoracoscopic lobectomy using prospective clinical studies. Methods: A total of 289 patients with early invasive adenocarcinoma undergoing thoracoscopic lobotomy were included. Blood was collected 1 day before surgery for miRNA detection. General patient information, operation duration, continuous drainage time of the chest, leukocyte count before and after operation, and postoperative pain scores were recorded. Follow-up occurred 3 months after surgery. Depending on whether chronic postsurgical pain occurred, the patients were divided into two groups. Risk factors for chronic postsurgical pain and related miRNA phenotypes were screened using binary logistic regression analysis.Results: Included in the final analysis was 232 patients, and the incidence rate of chronic postsurgical pain was 37.9%. Compared with the non-chronic postsurgical pain (CPSP) group, the CPSP group had higher body mass index, higher preoperative history of chronic pain, longer postoperative drainage tube indwellment duration, higher NRS scores 1, 2 and 3 days after surgery, and lower expression of miRNA 146a-3p , and higher expression of miRNA 550a-3p and miRNA 3613-3p in peripheral blood (P < 0.05). Logistic regression analysis showed that patient body mass index, preoperative history of chronic pain, average NRS score after operation and preoperative peripheral blood miRNA 550a-3P expression were risk factors for the development of chronic postsurgical pain.Conclusions: Preoperative body mass index, history of chronic pain, expression of miRNA 550a-3P in the peripheral blood, and postoperative numerical rating scale score were independent risk factors for CPSP after thoracoscopic lobotomy in patients with early invasive lung adenocarcinoma.

To make full use of urban household balcony space, an urban aquaponics system for balconies was constructed to investigate the purification effects of four different substrates (volcanic stone, ceramic pellets, ceramic rings, and nanorods) and six plants (mung bean sprouts, hollow cabbage, water celery, lettuce, leek, and water chestnut) on fish culture wastewater. The substrate material and plant combinations with the best purification effects were screened, and the results showed that volcanic stone had the strongest purification ability for ammonia nitrogen, chemical oxygen demand, phosphate, and total phosphorus, with removal rates of 88.8%, 63.1%, 95.1%, and 83.3%, respectively. Additionally, nanorods had a strong purification effect for ammonia nitrogen and total nitrogen. Compared to the other substrate types, there were more unique bacterial species on the surface of volcanic stone, among which amoeba species were the most dominant (92.42%). Among the six tested plant species, mung bean sprouts had the highest contribution to nitrogen uptake (94.96%), and water chestnut had the highest contribution to phosphorus uptake at 12.07%. Finally, the combination of nanorods and water celery was the best at purifying the wastewater. This study provides a theoretical basis and new ideas for the construction of urban aquaponics systems on balconies, which will help to achieve green farming and the efficient utilization of water resources.C.I.C.
