Engaging the Plural Parts of Science: Assessing Flat and Aspect Realization through an Integrative Pluralist Lens
Authors: Gillett Carl
Published: July 2022

I outline an integrative pluralist account of the models/ explanations in a case in physiology, cell biology, and molecular biology, including compositional models/explanations positing realization between properties. I then use this integrative pluralist framework to assess both the
older 'flat' theory and Piccinini's (2020) new 'aspect' view as accounts of realization in the sciences. Using our concrete scientific case, I show that these philosophical views of realization should be rejected for two reasons. First, the flat and aspect views of realization fail to accommodate
the layers of individuals, and/or powers, we find with realization relations in the sciences. And, second, because the flat and aspect accounts of realization cannot allow the integration between the models positing realization between properties, and the models positing composition between
activities, that we find in actual scientific practice.
Enseñanza de la investigación en la UNAH: La mirada de los actores en la Carrera de Pedagogía
Authors: Rodríguez Aguilar Lourdes Melissa , Alvarado Ángel Guillermo
Published: July 2022

La investigación es una función esencial de la Universidad, y la Carrera de Pedagogía de la Universidad Nacional Autónoma de Honduras (UNAH), contempla en el perfil profesional del futuro pedagogo la formación en investigación a través de tres asignaturas del plan de estudio vigente; esto presupone el desarrollo de capacidades investigativas en los estudiantes; sin embargo, ha sido una preocupación el logro de las mismas a partir de los aprendizajes obtenidos en este campo, lo que refleja una problemática a ser estudiada; estableciéndose como objetivo general de este estudio, analizar la situación actual de la enseñanza y del aprendizaje en las asignaturas de investigación desde la percepción de los actores (estudiantes y docentes). Este estudio fue cualitativo y descriptivo; la población y muestra correspondió a estudiantes que culminaron el taller de investigación y los docentes que impartieron el mismo. Algunos hallazgos que se pueden mencionar es que existe una contradicción entre la enseñanza de saberes técnicos-conceptuales y el desarrollo actitudinal en lo investigativo; las prácticas pedagógicas de los docentes se orientan a un paradigma de proceso-producto y no al paradigma interpretativo.
Las tierras de Don Jesús; Reforma y latifundio en Choluteca (1876-1891)
Authors: Izaguirre José Darío
Published: July 2022

Este artículo es una síntesis de un trabajo de campo realizado en 1989 en el municipio de Choluteca, Honduras. Los resultados del cual fueron publicados por el autor y otros dos colegas bajo el título “La evolución de la propiedad privada en el municipio de Choluteca (1876-1891)”. En esta síntesis seguimos las huellas de un propietario en particular, que nos permitió abordar el problema de la concentración de tierras en pocas manos. Esto durante un período de la historia de Honduras en el que el gobierno hondureño intenta modernizar el Estado e incorporarlo a las relaciones capitalistas de producción. La idea central en este trabajo es demostrar que, si bien las medidas de modernización funcionan a medias en ese municipio, no logran transformar las estructuras precapitalistas de producción existentes, por el contrario, estas reformas provocan “involuntariamente” la formación de grandes propiedades como la de uno de los personajes centrales de este artículo, el señor Jesús B. Guillén y las de otros agentes históricos que forman parte del estudio. Esta situación frena el desarrollo de una economía de mercado que conduce a la consolidación de una oligarquía terrateniente.

Totally Volume Integral of Fluxes for Discontinuous Galerkin Method (TVI-DG) I-Unsteady Scalar One Dimensional Conservation Laws
Authors: Rustum Ibrahim. M. , Elhadi ElHadi. I.
Published: July 2022

The volume integral of Riemann flux in the discontinuous Galerkin (DG) method is introduced in this paper. The boundaries integrals of the fluxes (Riemann flux) are transformed into volume integral. The new family of DG method is accomplished by applying divergence theorem to the boundaries integrals of the flux. Therefore, the (DG) method is independent of the boundaries integrals of fluxes (Riemann flux) at the cell (element) boundaries as in classical (DG) methods. The modified streamline upwind Petrov-Galerkin method is used to capture the oscillation of unphysical flow for shocked flow problems. The numerical results of applying totally volume integral discontinuous Galerkin method (TVI-DG) are presented to unsteady scalar hyperbolic equations (linear convection equation, inviscid Burger's equation and Buckley-Leverett equation) for one dimensional case. The numerical finding of this scheme is very accurate as compared with other high order schemes as the weighted compact finite difference method WCOMP.

Authors: Tweib Saleh Ali Khalifa , Ekhmaj Ahmed Ibrahim
Published: July 2022

Optimization of sludge composting has been analysed by co-composting of sewage sludge with food waste by using a bin composter with regular aeration. Two bin composting experiments were set up to study the effect of different mixing ratios of food waste from the wet market to sewage sludge from Al Hadhbah waste water treatment plant which is located in Tripoli on some physical and chemical characteristics of the resulted compost. The selected ratios were 1:2 (A) and 1:3 (B) of food waste to sewage sludge respectively. Composting was conducted for 100 days and the sampling from the mixtures was performed each five days. Temperature (T), pH, electrical conductivity (EC), total organic carbon contents (TOC %) and total nitrogen contents (TN %) were monitored during the composting. The ratio of C/N, inorganic residual material (ash content) and nutrient changes as represented by potassium (K %) and phosphorus (P %) contents was also determined. The compost produced in this study has a favorable ratio of C/N (13.43 for compost A and 14. 32 for compost B). With significant amount of nutrients (TN %, K%, P%) The results of analysis of variance (ANOVA) revealed a significant effect of elapsed composting time (at the probability level of 0.05) on T, pH, TOC%, K% and P%. The effect of composting ratio was insignificant (at the probability level of 0.05) on T, TOC %, TN %, C/N and P%. The multiple comparison results using Tukey’s test showed significance difference between the mean values of EC and K% among the composting ratio at the confidence level of 95%. Generally, the compost ratio of 1:2 was found to be the most suitable for use as organic fertilizer
Effect of Hormone Types and Concentrations on In Vitro Multiplication and Growth of Pineapple (Ananas Comosus (L.) Merr.) Cv Moris on Liquid MS Medium
Authors: Hamad Abdelhamid M.
Published: July 2022

The effect of two cytokinins, 6-benzyleaminopurine (BAP) and kinetin (KN) and two auxins, naphthalene acetic acid (NAA) and indole acetic acid (IAA) each applied at 10 concentrations with an increment of 0.5 mg/l in the in vitro shoot formation of Moris pineapple was evaluated in static liquid MS medium. The highest shoot formation (9 shoots per explant) was obtained in medium enriched with NAA but at high concentration (4.5 mg/l). The second best was 8 shoots per explant obtained in medium enriched with BAP at 2.0 mg/l. Out of 10 concentrations, NAA was better than BAP at the highest 5 and less at lowest 5 concentrations and at all concentrations both hormones resulted in production of more shoots per explant than hormone free medium. Except at two concentrations, NAA and BAP were better than KN. Either one of these three hormones, BAP, NAA, KN could be claimed, depending on the tested range of concentrations, better than the others for in vitro shoot formation of Moris pineapple. All of the IAA concentrations, on the other hand, failed to produce more shoots than hormone free medium. But, the longest shoot (56 mm) obtained in medium enriched with IAA at 2.5 mg/l and the shortest shoots (6 mm) on medium enriched with KN at 4.0 mg/l. Seven of the IAA concentrations resulted in shoots longer than hormone free medium (27 mm) while the shoots length on the BAP, NAA and KN contained media was two times shorter than hormone free medium. BAP at 2.0 mg/l was the best treatment for multiplication and IAA at 2.5 mg/l was the best for elongation of Moris pineapple.
Effect of sucrose, pH and medium states on in vitro shoot formation and growth of Moris pineapple (Ananas comosus L. Merr.)
Authors: Hamad Abdelhamid M.
Published: July 2022

The effect of medium states (solid, semi solid and liquid) of full strength MS medium enriched with  6-benzylaminopurine (BAP) at 2.0 mg/l on in vitro shoots formation and shoot length of Moris pineapple were tested at 16 combinations of sucrose (10, 20, 30 and 40 g/l) and pH (5.0, 5.7, 6.0 and 6.5). The highest shoot formations (7 shoots/ explant) were obtained in liquid and solid media each adjusted to pH 5.0 but enriched with different sucrose concentrations, sucrose at 20 g/l for liquid and at 30 g/l for solid medium. Increasing the medium sucrose to 40 g/l or adjusting the medium to pH 6.0 caused 50 % decline in the shoot formation capacity in both medium states. However, while that decline could be reversed in liquid medium by adjusting the pH to 6.5, such pH adjustment failed to overcome the inhibitory effect of the sucrose at 40 g/l in the solid medium. Out of 16 combinations of sucrose and pH, liquid medium (no agar added) was better than solid (7.0 grams of agar /l) and semi solid (3.5 grams of agar /l) at 8 combinations, equal to solid at 4 and to semi solid at 5 combinations and less than solid at 3 and than semi solid at 2 combinations. Adopting of the commonly used  combination of sucrose at 30 g/l and pH 5.7 not only did not fit all medium states but also resulted in lower shoot formation (4 shoots) than the possibly obtainable (7 shoots). Simple modification of the medium pH (pH 5.0 instead of 5.7) doubled the rate of shoot formation.
Effect of the Seasons and Salt Concentrations on Microbial Load of Wet-Salted Fermented Product (Fassiekh)
Authors: Ahmed Egbal Osman , Ali Mohamed Eltaher
Published: July 2022

The study aims at investigating the microbial load of wet-salted fermented product (a traditional fermented product in Sudan named locally; fassiekh) and determination of total viable bacterial count, according to salt concentrations (20%, 25% and 30% of the fish weight) and seasons (summer, autumn and winter) variations. Fessiekh processed from popular fessiekh fish species (Hydrocynus  spp, local name: Kass).The isolation and identification of bacteria and mould were examined for the microbial quality of fassiekh. The total viable count of bacteria in fresh fish used as raw materials in fessiekh preparation (Hydrocynus froskalii), ranged from 2x103-5.5x103cfu/g. The concentrations of salt had direct effect on the microbial quality of salted Hydrocynus froskalii. It was observed that the total bacterial count was increased during the first five days in summer and autumn while at winter season it showed increases till the tenth day, followed by remarkable decreasing. The counts began to decrease as salting proceeded. Five Staphylococcus spp (Staph.aureus, Staph.rostri, Staph.lentus, Staph.epidermidis and Staph.pyogen) were isolated from all samples of salted fish and appraises about 46.77% of total isolates. Also three species of Micrococcus were isolated (Micro.leuteus, Micro.roseus and Micro.lactis), and Aerococcus viridans, and they represented 36.17% & 12.9% of all isolated samples respectively. The viable bacteria counts of commercial fessiekh were significantly higher (p<0.05) when compared to the experimentally salted fish at the same salt concentrations. No yeasts or fungi were detected in tested samples.

Authors: Wani Afaq , Chauhan K.
Published: July 2022

Pollen grains have helped the species of plants to adapt to life on land, be able to disperse its pollen, and fertilize the female eggs to produce new seeds that would give rise to new plants. Pollen morphology is closely related to its function. Pollen grains of Bauhinia variegata were found triangular in shape with three germ pores and remained viable at 4+1oC for more than six months. Pollen size varied from 47.61-95.22 µm. Maximum pollen germination occurred in 15.0 per cent sucrose solution.

Osteoporosis affects millions of women around the world, but female athletes are at particular risk. These female athletes are at a higher risk due to the stress of their intensive workouts than the overall female population. In female athletes, the absence or suppression of menstruation results in a low peak bone mass, which weakens their bones. Combined with their physical activity, this domino effect dramatically increases their risk of stress fractures. Increased understanding of the dangers of osteoporosis may help female athletes avoid or decrease the symptoms of the disease. The purpose of this study is to educate female athletes on the need for ssreening the techniques for identifying and treating this disease.

Social enterprises as an alternative model to outsourcing in Universities: A theoretical premise.
Authors:   University of Namibia, Chikadzi Victor
Published: July 2022

The past three decades have been characterised by massive restructuring of public universities within Southern Africa. In line with the neo-liberal policy framework adopted in many countries, service provision in most public universities has become privatised and highly commercialised. As a result, outsourcing of support service functions to private service providers has become a widely entrenched feature of public universities in Southern Africa, reflective of the global trends. This has largely resulted in poor welfare for workers and escalating costs of service provision. Given the profit motive which is the primary driver for companies bidding for contracts to provide services in universities, the compromised welfare of workers and students will remain an ‘achilles heel’ of outsourcing. In this paper I argue that, the social enterprise can be adopted as a cheaper and effective alternative economic model to outsourcing in Universities

The role of work engagement and work meaningfulness on turnover of nurses in Rundu, Namibia
Authors:   University of Namibia, Moyo S , Hlatywayo C K ,   University of Namibia, Murangi A ,   University of Namibia
Published: July 2022

Turnover, in the nursing profession seems to be problematic and this jeopardized the mandate of delivering safe and effective care. The nursing sector has one of the highest in employee turnover around the world. Looking into work engagement and work meaningfulness can be used as mitigating factors which organisations can consider to curb turnover. In the Namibian context literature on nurses’ engagement and work meaningfulness is inadequate. A cross-sectional survey design was used. A total of n=168 nurses from Rundu hospitals and clinics, participated in the study. Findings revealed that there is no statistically significant relationship between turnover and work-engagement (r=0.095; p=0.222) of nurses in Rundu, Namibia. Findings also revealed that there is no statistically significant relationship between turnover and work-meaningfulness (r=-0.003; p=0.966) of nurses in Rundu, Namibia. A positive and statistically significant relationship between work-engagement and work-meaningfulness (r=0.587**; p=<.0001) was confirmed. Additionally, work meaningfulness was statistically found to moderate the relationship between turnover and work engagement (F = 43.589; df = 2; P = <.000; R2 = 0.589). Stakeholders concerned (.i.e. Ministry of Health and Social Services) should devise strategies to enhance employee level of engagement and work meaningfulness which inevitably will foster positive work outcomes for the health sector.

Published: July 2022

In December 2019, the SARS-CoV-2 virus emerged in Wuhan, Hubei Province, China, and later spread rapidly to other parts of China and eventually across all countries around the world, including Namibia. Despite causing severe to fatal acute respiratory syndrome, there are no known cures for the SARS-CoV-2 virus, only preventive measures such as social distancing, hands sanitizing, hands washing, wearing masks, and full-dosed COVID-19 vaccination. For this reason, this study was aimed at assessing the Knowledge, Attitudes and Practices (KAP) towards COVID-19 prevention measures among private clinic patients in Windhoek during 1 October to 30 November 2021. A cross-sectional analytic study using quantitative method was used with data collected in a single roundamong patients visiting two private clinics in Windhoek. Results showed that more than half (62%) were females, 58.5% were single and 70% attended tertiary education and 71% were employedas of 30 November 2021. In addition, at least 90% of the participants knew each of the COVID-19 prevention measures, while more than three-quarters (79%) had comprehensive knowledge of the measures, with 65% of them knowing that one needs two shots of theCOVID-19 vaccine for immune protection against the virus. At least 90% of the participants were in favour of practicing each COVID-19 prevention measure, while more than three-quarters (81.5%) had comprehensive positive attitude towards the measures in general. However, less than half (48%) of the participants believed that the COVID-19 vaccines can prevent one from the virus. Moreover, more than 95% of the participants were practicing each COVID-19 prevention measures, with 90% practicing all the prevention measures at the same time, with the exception of the COVID-19 vaccination as only 37% of the participants were vaccinated. Seeing as the participantshad very good knowledge, attitudes and practices towards COVID-19 prevention measures, with barely more than a quarter of them vaccinated against COVID-19, the health education and awareness of COVID-19 in the country must continue in order to maintain the very good KAP of its prevention measures in Windhoek.
Modelling state preferences among airline travellers in Namibia: a case study at Eros airport and Hosea Kutako international airport

Published: July 2022

Stated preference experiments are become an increasingly popular survey methodology for investigating air traveler's choices. Analysis of this behaviour, which is an element of the demand prediction, helps for a better future planning and development of competing airlines. In this paper, emphasis is stressed on the stated preferences of passengers in choosing between low cost carriers (LCC) and full service carriers (FSC). A binary logit, probit and latent class models were employed on the primary data collected from departing air passengers at Eros and Hosea Kotako International airport in Windhoek, Namibia, to model passengers' stated preferences and examine the determinants of carrier choice between LCC and FSC in Namibia. Major findings show that airfare, age, income, and purpose of travel are significantly important with respect to passenger choice. Furthermore, it was observed that passengers have different preferences for different destination region be it domestic, regional and international. For domestic and regional flights (short haul) they prefer LCC, while for international flights (long haul) they opted for FSC. In addition, majority of the passengers were travelling for business purposes, hence their tickets were bought by their respective employers. Most passengers indicated that they were willing to fly LCC if it was available in Namibia because of it's low fares. There was an indication that air tickets were not affordable and these are a big concern to passengers. Presumably, if ticket prices can come down or introduce a LCC in Namibia then many consider flying. This study concluded that, based on the interviewed passengers' profiles, the best and appropriate carrier in Namibia is a low-cost carrier. Introducing a LCC in Namibia might be a viable alternative which may ensure sustainability.

Published: July 2022

Schizophrenia is a common mental disorder in Namibia and affects about 20 million people worldwide. Risk factors for schizophrenia in Namibia have not been extensively investigated. The objective of the study was to establish prevalence and factors influencing schizophrenia symptoms based on secondary data from the 2013 Namibia Demographic and Health Survey (NDHS). Descriptive statistics were computed to profile the background characteristics of the sample. Chi-square tests were conducted to assess association between socio-demographic variables and schizophrenia symptoms. Binary logistic regression was performed to establish determinants of schizophrenia symptoms. The prevalence of schizophrenia symptoms was 12.4% (13.6% among females and 11.0% among males). Regression results indicated that females (OR=1.159, 95% CI: 1.022-1.314, p=0.021) were more likely to have schizophrenia symptoms compared to their male counterparts. Those who resided in urban areas (OR=0.699, 95% CI: 0.609-0.803, p<0.001) were less likely to have schizophrenia symptoms compared to those who resided in rural areas. Those with no formal education (OR=0.378, 95% 0.273-0.523, p<0.001); those with primary education (OR=0.646, 95% CI: 0.501-0.834, p<0.001) and those with secondary education (OR=0.619, 95% CI: 0.495-0.775, p<0.001) were less likely to have schizophrenia symptoms compared to those with higher education. Results also showed that those who had never married (OR=0.275, 95% CI: 0.225-0.335, p<0.001); the married (OR=0.229, 95% CI: 0.184-0.284, p<0.001); and those living with a partner (OR=0.283, 95% CI: 0.225-0.355, p<0.001) were less likely to have schizophrenia symptoms compared to those who were on separation. Respondents who did not consume alcoholic drinks (OR=0.597, 95% CI: 0.526-0.677, p<0.001) were less likely to have schizophrenia symptoms compared to those who consumed alcoholic drinks. Schizophrenia symptoms were not significantly influenced by wealth index (p>0.05). There is need to step up gender-specific mental health programs especially in rural areas. Efforts to stabilize marital relationships at national level should be strengthened. Mental health could also be improved through drug abuse prevention and rehabilitation programs.

The face-to-face learning engagement of students and teachers within the school has been suspended due to the Covid-19 pandemic. Hence, the Department of Education’s mantra of “no child left behind,” paved the way for Modular Distance Learning (MDL) implementation as an immediate response to ensure educational continuity. This qualitative case study approach was conducted in Zamboanga del Sur National High School – Senior High School. The study employed multiple case studies on STEM students’ experiences in MDL amidst the pandemic. Findings revealed that the challenges encountered by STEM students on MDL are more prevalent on adjusting to a new setup, poor internet connection, and power interruption, lack of motivation, lack of presence of teachers, and learning loss, doing their households while trying to finish their modules. Students felt foreign since everything is new and described it as hard, overwhelming, and unideal. They had a hard time adjusting, notably for the first few weeks since self-learning is new to them but making self-learning their guide throughout everything is much more difficult. Nevertheless, students emphasized that a sense of independence in learning, as it is a non-interactive manner, was cultivated. These claims were also confirmed by a teacher who handles STEM students and a parent whose learner is enrolled in the said strand. Both agreed that the learners are faced with vast challenges during this learning period. With all the challenges mentioned, students’ central coping mechanism to battle against is to master the art of time management. Along with this is watching YouTube or playing mobile games during their self-imposed vacant time and staying positive. Accordingly, an intervention program can be initiated to mitigate the situation. The Give E-CARE (Giving Electronic – Careful Attention and Relief Everywhere) program may benefit the students, the teachers, the parents, and of course, the school on this pandemic education.

Published: July 2022

35 patients with bronchial asthma were examined in order to determine the optimal criteria for evaluating the effectiveness of a separate manual procedure (medical massage). It was established that changes in the respiration function after the massage procedure, according to the indicators obtained by the methods of general plethysmography and spirometry, were multidirectional. Bronchial resistance (Raw) significantly decreased, and bronchial specific conductance (Sgaw) increased (-19.50.52 and +23.93.9%, respectively; p < 0.05), with a simultaneous decrease in functional residual capacity by 8.500.98%. The subjective sensation of shortness of breath also significantly decreased (VAS= - 14.810.8%; p < 0.01). Bronchodilation response after medical massage in terms of SGaw correlated with VAS dynamics (r=0.642, p<0.05). At the same time, the traditionally determined indicators of the respiratory function decreased (PEF -12.01.8%, FEV1 = -9.65.1%), and it is interpreted as a deterioration in the respiratory function according to the generally accepted assessment. Therefore, a direct assessment of manual exposure should be based on clinical and functional indicators that reflect the targeted manual impact on the pathogenetic mechanisms of the disease.

A standard X-ray examination makes it possible to identify the presence of typical signs of osteochondrosis, as well as to reveal a number of local X-ray changes in the form of configuration distortions of the spine. The X-ray study data showed that after a course of osteopathic treatment patients with lumbar osteochondrosis demonstrated the restoration of the distorted configuration of the spine (26.3%), elimination of flexion (27.4%) and extension (28.5%) restrictions. The complex therapy, which included osteopathic treatment, facilitated the more evident positive dynamics of structural and functional changes in the lumbar spine. The comparative analysis of clinical and radiological manifestations and data of structural and functional changes in the vertebral motor segments in patients with lumbar osteochondrosis, who underwent osteopathic treatment, indicates the high efficiency of the proposed complex of restorative measures.

The development of customer experience theory in the field of retailing has drawn a lot of attention. One of the developments areas is related to the relationship between customer experience and brand. This study aims to contribute in the explanation of the relationship between private brand trust, private brand experience, private brand attitude and repurchase intention with multigroup analysis of gender. The hypotheses proposed in this research tested with 100 respondents consisting of 50 women and 50 men. The approach used is variance based partial least square structural equation modelling (PLS-SEM). We employed a multi-group approach using two subsamples consists of man and woman. Our finding indicates that there is no difference between men and women in all hypotheses proposed. Another findings are private brand experience influenced private bran trust and repurchase intention but no private brand attitude. More over private brand trust influenced private brand attitude and purchase intention. Finally, private brand attitude affected repurchase intention.

BACKGROUND:Semen cryopreservation results in deleterious effects on spermatozoa, including lipid peroxidation and a reduction in the total antioxidant components of seminal plasma. The ultimate outcome of these changes is a reduction in post-thaw semen quality. A mitochondrial derived peptide, humanin, a potent cytoprotective and antioxidant agent was used in the present study.OBJECTIVE:To evaluate the efficacy of a mitochondrial-derived peptide, humanin to improve the post-thaw quality of buffalo spermatozoa.MATERIALS AND METHODS:A total of 18 ejaculates from three Murrah buffalo bulls (n=6 each) were collected. Each ejaculate was divided into four aliquots. The first aliquot was diluted with standard EYTG dilutor (Group I, control), whereas the other three aliquots were diluted with EYTG supplemented with 2 μM (Group II), 5 μM (Group III) and 10 μM humanin (Group IV), respectively. Semen was evaluated for physico-morphological and functional attributes such as progressive motility, viability, abnormality, acrosome integrity, plasmamembrane integrity of fresh samples, pre-freeze and post-thaw stages. Oxidative stress parameters [lipid peroxidation (LPO) and total antioxidant capacity (TAC)] were also measured at the pre-freeze and post-thaw stages.RESULTS:Humanin s upplementation resulted in significantly higher (p≤0.05) post- thaw motility in all treatment groups and, higher (p≤0.05) viability in Groups III and IV in comparison to the control at the post-thaw stage. Spermatozoa with intact acrosome and plasma membran e were higher (p≤0.05) in Groups III and IV as compared to Group s I and II. The LPO levels at the post- thaw stage were found to be lower (p≤0.05) in all treatment groups versus the control group, whereas, higher (p≤0.05) TAC value s were recorded in Groups III and IV in comparison to the control and Group II.CONCLUSION:Humanin supplementation in the extender improved the freezabilty of buffalo spermatozoa.

BACKGROUND: Using sulfated polysaccharides (SP) in fish sperm freezing medium promotes cell maintenance. OBJECTIVE: To evaluate the effect of different SP concentrations, extracted from two seaweeds (Gracilaria domingensis and Ulva fasciata), as a supplement
to the sperm freezing medium of Prochilodus brevis . MATERIALS AND METHODS: Five semen pools were diluted in a solution composed of 5% glucose, 10% dimethyl sulfoxide (DMSO) and different SP concentrations (0, 0.5, 1.0, 1.5, 2.0, 2.5 or 3.0 mg/mL). The samples were cryopreserved
and, after 7 days, rewarmed and analyzed for morphology, plasma membrane integrity, DNA integrity, mitochondrial activity and sperm kinetics [total motility, progressive motility, curvilinear velocity (VCL), straight line velocity (VSL), average path velocity (VAP), linearity (LIN), and wobble
(WOB)]. RESULTS: There was no interaction between seaweed and SP concentrations. Similar effects were observed with SP extracted from the two seaweeds, regardless of concentration. When comparing the SP concentrations, regardless of the seaweed, 1.0 mg/mL SP showed better results for
VCL and VSL. For VAP and WOB, 1.0 mg/mL SP showed better results, but differed from 3.0 mg/mL. LIN followed the same pattern, but differed from SP at 2.5 and 3.0 mg/mL. For progressive motility, 1.0 mg/mL G. domingensis showed superior results compared to the control. For mitochondrial
activity, G. domingensis was superior to U. fasciata, regardless of concentration. The lowest concentrations (0.5 and 1.0 mg/mL) showed the best results, regardless of the seaweed. However, the control was superior to all treatments tested. CONCLUSION: G. domingensis
SP at the lowest concentrations might be a potential supplement to the P. brevis freezing medium.

Guangdong, as a province with large population and economy, has huge tourists market demand. The paper predicts people's preference for the development of "blockchain + rural tourists" under blockchain technology, and then applies the characteristics of blockchain itself to rural tourists in a more targeted way. The paper establishes a vector autoregressive VAR model and a Prophet-LSTM-based prediction model for the number of tourists based on the data of tourist reception in Guangdong Province from April 2000 to November 2020. The VAR model is used to empirically prove the impact of blockchain background on the number of rural tourists; a combined Prophet-LSTM-based prediction model is established to forecast the number of rural tourists in the next two years. The results show that blockchain technology has influenced the number of rural tourists in Guangdong Province to a certain extent; n addition, in the market in the next two years, the number of travelers will show a fluctuating upward trend, for which the demand will continue to expand, and blockchain + rural tourists has market potential.

Authors: Zhu Dan
Published: July 2022

In order to address the crowding problem in college cafeterias, this paper classifies and summarizes the factors that may cause the crowding in college cafeterias by reviewing a large amount of related literature, establishes a fault tree model of the crowding in college cafeterias on this basis, and transforms it into a Bayesian network to construct a Bayesian network model of the crowding in college cafeterias. Then, we collect the case data of students' opinions about the cafeteria crowding event in Dalian Maritime University by conducting a questionnaire survey and normalizing them, and use the two-way inference function of Bayesian network to calculate the influence degree of each influencing factor on the cafeteria crowding event in colleges and the importance degree of each influencing factor when the cafeteria crowding event occurs. Finally, we find that the short meal service time, few cafeteria stores, insufficient cafeteria staff, low level of informatization and serious seat occupation problem are the five key factors that are most likely to lead to the occurrence of cafeteria crowding events.
Fixed Asset Investment and Enterprise Performance Based on the Moderating Effects of the Nature of Equity
Authors: Lin Yiting
Published: July 2022

Decisions on fixed asset investment have always been the top priority of enterprise production, operation and management. The success or failure of major investment decisions will be directly related to the performance, survival and development of enterprises. How fixed asset investment affects enterprise performance is still inconclusive, indicating practical significance of continuous in-depth research. In addition, the influence of fixed asset investment and enterprise performance might vary between SOEs and non-SOEs. Therefore, this paper attempts to integrate the nature of equity, fixed asset investment and enterprise performance into an analysis system, combined with the institutional environment with Chinese characteristics, to examine the heterogeneity of fixed asset investment-enterprise performance relationship between SOEs and non-SOEs. Results showed that fixed asset investment of A-share listed companies from 2015 to 2019 was significantly negatively related to enterprise performance. Compared with non-SOEs, the scale of fixed asset investment of SOEs was more dispersed, and the increase in fixed asset investment of SOEs had a more significant negative impact on enterprise performance.
