The spatial variability of cellulase, amylase, protease and pectinase activities were evaluated from four zones of West Bengal, India. The enzyme production data was plotted on the map of the study areas and spatial variability of cellulase, amylase, protease and pectinase activity was obtained. Available nitrogen of the soil was the most variable parameter with changing enzyme activity. It also varied with the available phosphorus but the variation was least with organic carbon content of the soil. Amylase was correlated with pectinase, available nitrogen and phosphorus. Cellulase was correlated with only available nitrogen; protease was correlated with pectinase and Pectinase was correlated with available nitrogen of the soil of the four sampling zone. Except protease activity, other enzymes were significantly correlated with bacterial density of the soil. These findings ultimately develop relationship among soil major nutrients and the map can be used for future enzyme bioprospecting in West Bengal, India.

Published: October 2021

The present study conducted to investigate the haematological changes and changes of blood glucose level in male albino rat due to cold stress. In this experiment normal 12:12 light dark phases were maintained for all the groups. Control group was kept at normal room temperature (22 ± 1). A (4°C), B in (0°C), C (4°C and 0.30 mg alprazolam / kg body weight /animal), D (0°C and 0.30 mg alprazolam/ kg body weight/ animal. E2 group was treated with (4°C and 1000 mg/kg body weight methanolic extract of Withania somnifera root extract /animal). F2 group was treated with (0°C and 1000 mg/kg body weight methanolic root extract of Withania somnifera / animal). The blood glucose level was significantly increased in stressed rats compared to the control animals. The results were also consistent with the exposure to the stress and chronic restraint stress. Action of Alprazolam over cold stress treated group significantly reduced the blood glucose level. Whereas methanolic root extract of Withania somnifera in low and high doses also showed significant effects to the control anxiety like effects on blood glucose level. Alprazolam + different stress treated groups in different experiment at conditions show significant changes in its haematological parameters in comparison to the stress treated group. Whereas herbal medicine (i.e., methanolic root extract of Withania somnifera) when applied to different stress treated group showed more significant result, compared to the Alprazolam+ different stress treated groups. The positive safe anti stress effects of the herbal plant medicine prove that the tribal medicines have the potentiality to act effectively and can be used as safe medicine for antistress purposes.

Lacan's Theory of Desire and Its Practical Value
Authors: Wang Wengqiu , Jia Yupeng
Published: October 2021

The word "desire" is one of the core terms in Lacan's psychoanalysis. As the famous saying of Lacan: "the desire of man is the desire of the Others", Lacan's theory of desire is based on Hegel - Koyev's theory of desire. By falsifying the subject, Lacan developed a unique theory of desire, that is, desire is the alienated subject, the fantasy formed in the pursuit of what Freud called the Das Ding which Lacan called the Objet petit A, and finally the fantasy constructs desire retrospectively. The study of Lacan's theory of desire helps to provide more sections for the study of contemporary social phenomena and social development.

Published: October 2021

Children are particularly impressionable and at risk during a global public health crisis, making it essential to examine their unique perspectives. To hear and understand sub-Saharan African children’s experiences with the COVID-19 pandemic, we conducted an exploratory qualitative analysis based on interviews with 51 children, ages 9 to 13, from Nigeria, Tanzania, and Sierra Leone. Applying the organization of Bronfenbrenner’s ecological systems theory, we reveal how COVID-19 affected children’s daily lives and domestic challenges, schooling and neighborhood issues, media use (and its relationship to knowledge and fear of the disease), perceptions of the country, and government response, and thoughts of religion and hope. Children’s responses dif-fered greatly, but patterns emerged across sex, age, household size, religion, and country. This study offers guidance and recommendations for meeting the needs of children, especially in times of crisis.
Safety of transport and retrieval of patients on extracorporeal membrane oxygenation during the peak of COVID-19 pandemic in the State of Qatar
Authors: Shehatta Ahmed Labib , Abdussalam Ahmed Lutfe , Deloso Ferdinand , Howard Ian , Alinier Guillaume , Ibrahim Abdulsalam
Published: October 2021

Background: Transport and retrieval of patients on extracorporeal membrane oxygenation (ECMO) support can be hazardous with complications reported for up to 27% of patients. Transport of COVID-19 patients on ECMO requires appropriate training, resource allocation, meticulous planning, effective communication and co-ordination. Strict adherence to infection control procedures and appropriate use of personal protective equipment is recommended. The Extracorporeal Life Support Organisation registry reports 43% in-hospital mortality of COVID-19 patients supported on ECMO. This includes in-house and retrieval ECMO cases. Methods: Between March 1st and September 30th 2020, 32 confirmed COVID-19 positive patients underwent peripheral cannulation followed by transportation to the Medical Intensive Care Unit (MICU) at Hamad General Hospital. Mobile ECMO is complex and time consuming. Following arrival at the bedside and thorough clinical assessment, the ECMO consultant may decline, recommend optimisation of the care provided, or opt for cannulation and initiation of ECMO. Cannulation can be performed at the bedside or in the operating room. Following stabilisation, the patient is transferred for computed tomography imaging and then transported by ambulance to hospital (). Finally, another transfer from hospital entrance to the MICU takes place. All these phases pose risks for errors and complications unless vigilance, teamwork and continuous effective monitoring and co-ordination is observed. Patients were evaluated for age and severity of illness (). In addition, all major transport-related adverse events were reported and analysed. Major transport events are cardiac arrest, ECMO emergencies (membrane or mechanical failure, air embolism, accidental decannulation, or significant cannula dislodgement), significant arrhythmia, severe bleeding or cardio-respiratory instability, and vehicle breakdown/malfunction. Findings: The majority of our patients were critically ill with high probability of mortality as depicted by SOFA and APACHE2 score. 29 out of 32 patients were male. None of our patients suffered major complications during transportation. Conclusion: This small case series demonstrates transport and retrieval on ECMO for COVID-19 positive patients can be safely undertaken provided appropriate expertise, protocols and resources are used.

Published: October 2021

Background: Hamad General Hospital is the main provider of hemodialysis (HD) in Qatar, for approximately 650 patients per year. Over 60% of these patients have Diabetes Mellitus (DM) and 55% of them suffer from end stage renal disease (ESRD). 2% of ESRD patients develop DM after their first year of dialysis. The aims of this quality improvement study were early DM detection, risk factors modifications, and reduction of diabetes complications in our patients. Methods: A risk assessment tool was adapted to identify the risk level of HD patients to develop DM. They were screened to determine their risk score across 8 categories. Six categories (gender, history of gestational diabetes, family history of high blood pressure, diabetes, physical activity and smoking) were scored 0 to 1, age was scored 0 to 3, and relationship between weight and height scored 1 to 3. (Overall score range: 1-12). Patients were classified into two groups: a low-risk group (score < 5) and a high-risk group (score ≥ 5). Patients were referred to different medical specialties for further management according to the risk factor and a lifestyle modification management plan was set individually. Results: 189 non-diabetic dialysis patients were screened in the first quarter of 2020, their mean age was 51 years-old, and 69% were male. Forty-three percent of patients were found to be at high risk of developing DM. The most important risk factors were family history (55%), obesity (40%), age >60 years (32%), low physical activity (14%), and smoking (11%) (). Thirty-seven percent of patients were referred to the obesity clinic, 10% to the smoking cessation clinic, 5% to physiotherapy, and 100% of patients were referred to the multidisciplinary care (). Conclusion: Screening for diabetes is pivotal for early detection and risk factor modification in dialysis patients. We recommend quarterly data assessment and evaluation so patients can be managed according to the findings.

Authors: Soliman Mohamed Ahmed , Christian Cosme Villar Ralph , Jeprel Nashwan Abdulqadir
Published: October 2021

Background: Clinical trial registries ensure the transparency and accountability of clinical trials (CTs) internationally. It is important to safeguard the public's safety through the delivery of quality clinical research. Since the start of the COVID-19 pandemic there has been a tremendous increase in the number of CTs globally. The MENA region has an opportunity to increase its overall contribution to CTs, which is less than 1%, in particular, through Qatar given its substantial economical growth and healthcare advancements. This review aims to explore the characteristics of clinical trials performed in Qatar, registered on ClinicalTrials.gov. Methods: The ClinicalTrials.gov registry was searched for trials conducted in Qatar using the appropriate keywords and advanced search options. Data retrieved was downloaded and sorted within Microsoft Excel then reviewed by two independent co-investigators. Results: The preliminary search yielded 143 entries with 32.1% (46) registered as multisite trials. The first trial in Qatar was registered in 2005. There has been a noticeable increase in CTs with its peak in 2020 (), with currently 39.1% (9) of registered CTs on COVID-19; 83% of the completed studies were published, with the highest number of publications (8) in 2020 (). Several specialties contributed to the CTs, with the highest participation and contribution rate of 31 CTs being in the field of pediatrics. Furthermore, some variations were found in recruitment status as reflected in with ∼65% (93) of studies being interventional and ∼35% being observational. Conclusion: The CTs conducted in Qatar are still relatively low despite the rapidly evolving healthcare system. Immediate updates and follow-ups could be considered by research investigators in Qatar with regards to CTs registration and updating. Further analysis is needed to elucidate the discrepancy of CTs reporting and to increase the contribution of CTs from Qatar to improve the health of its people.

Published: October 2021

The increasing demand for electrical energy and the decreasing supply of fossil fuels in recent years have increased the cost of electrical energy. So that the culture of saving electrical energy is a habit that must be cultivated in the community. On the other hand, energy-saving behavior cannot be realized massively without a support system that can control energy use. With these concerns, it is necessary to develop a method that encourages a culture of saving electrical energy. This paper proposes a system that supports active energy efficiency methods that can support an energy-efficient culture. This system is an electric power monitoring system that is integrated with a smart electrical panel that continuously monitors the use of electrical energy and can control electrical loads automatically, record electricity usage, provide comprehensive reports and analyze energy usage. The method used to carry out this research is research and development. This research has produced a prototype of electrical power control and monitoring system that has a smart panel based on a raspberry PI 3 and PZEM-004t power energy meter. The monitoring system performs and executes automatic control of electrical loads. The system can also provide reports in the form of data monitoring in daily, weekly, monthly or annual period. From the test results, it can be concluded that the system can work well. This research is expected to contribute to providing a system that can support government efforts in saving energy.

In this Editorial, we take the opportunity to expand on the second Journal of University Teaching and Learning theme, Developing Teaching Practice. Building on Editorial 18(4), which articulated changes to higher education in the period roughly between 1980 and 2021, we believe it is pertinent to explore the changing conceptions of academic as ‘teacher’. We use Engeström’s cultural-historical activity theory as a lens to consider how higher education teachers are situated in the current context of rapid changes arising from the COVID-19 pandemic. We explore possible future purposes of higher education to consider flow-on impacts on the purpose of its teachers and how their roles might change to accommodate future expectations. We assert the need to challenge the notion of the academic as a person who is recruited into higher education largely because of their subject matter expertise and maintains strong commitment to teaching expertise that is grounded in scholarship, critical self-reflection, and agency. In our various teaching and leadership roles, and consistent with the literature, we have observed paradoxical outcomes from the nexus between risk, innovation and development, driving risk aversity and risk management, with significant (contradictory) impacts on teaching, teachers and student learning. The barriers to implementing innovative curricula include questions of do students get a standardised and ‘safe’ educational experience or are they challenged and afforded the opportunity to transform and grow? Are they allowed to fail? Related, do teachers have genuine agency, as an educator, or are they positioned as agents of a higher education system? We explore these questions and invite our readers to engage in serious reflexivity and identify strategies that help them question their attitudes, thought processes, and assumptions about teaching and student learning. We welcome papers that contribute values-based conversations seeking to continue exploring ways of dealing with and adapting to change in our teaching practices, case studies of learning through failure, change and adaptation and the development of the field.
One step at a time: Aligning theory and practice in a tertiary embedding initiative
Authors:   University of Sydney, Australia, Economou Dorothy
Published: October 2021

The widespread, theoretically-informed practice of curricula embedded academic language and learning development is generally acknowledged as the most productive method of improving tertiary student outcomes. University-wide comprehensive support, however, for the collaborative processes of interdisciplinary research, design, resource and staff development required to achieve this, is not common. Yet many practitioners continue to engage in embedding initiatives in response to faculty requests, despite institutional constraints on time and funding. This paper documents one such initiative, a common yet under-reported type, conducted one small step at a time over a number of years in a firstyear core unit in the architecture faculty of a large metropolitan university in Australia. The paper aims to respond Wingate’s (2018) call for more thorough documentation of pedagogic principles applied in embedding practice to allow for replicability. This granular examination of the first implementation and later refinements of the initiative shows how aligning practice with proven theoretical models, in this case, Systemic Functional Linguistic (SFL) and the SFL-based pedagogic model, the Teaching/ Learning Cycle (TLC), proved fruitful in constrained circumstances.

Published: October 2021

The design of university training programs affects academic outcomes therefore, exploring the various design components in the academic program is important. The study explored how participating in a co-teaching-based professional development program (PDP) affects novice teachers' self-efficacy, their attitudes toward the profession, and their application of pedagogical practices; and measured the correlation between self-efficacy and attitudes and how it is influenced by the application of pedagogical practices. We used a questionnaire answered by 300 novice teachers and interviews with 15 teachers who participated during their academic studies in the co-teaching-based PDP. The results indicated a higher sense of self-efficacy and attitudes toward the profession among teachers who participated in the co-teaching-based PDP. The relationship between teachers' self-efficacy and attitudes was partially mediated by six pedagogical applications. The findings provide insights on designing PDP that may contribute to ameliorating the entrance of novice teachers into the teaching profession with teaching skills that will sustain over time.
Collaborative testing in Sport and Exercise Degrees: A comparison of first and third year students' perceptions
Authors: Headrick Jonathon , Harris-Reeves Brooke , Daly-Olm Talei
Published: October 2021

Collaborative testing is recognised as an effective assessment approach linked to positive student outcomes including enhanced test performance and reduced assessment anxiety. While collaborative testing approaches appear beneficial to university students in general, it is unclear whether students from different year levels benefit to the same extent. Therefore, the overarching aim of this study was to compare the perceptions and performances of first and third- year undergraduate students taking part in collaborative testing on multiple occasions during a semester. It was predicted that first-year students would perceive the collaborative testing opportunities as more beneficial than third-years given their limited formative experiences with university assessment. Further, it was expected that students would generally perform at a higher level on collaborative versus individual tests in line with previous work. Student performance and perceptions of collaborative testing were collected on two occasions within a semester over a period of two years in both a first-year and third-year course. Quantitative and qualitative results revealed that first-year students were more receptive and perceived more benefits relating to collaborative testing than third-years despite the fact both cohorts generally performed at a higher standard on the collaborative versus individual components. These findings suggest that while collaborative testing is considered beneficial to most, if not all, students, the benefits appear to be greater for first-year student cohorts.

The current article presents an innovative technical solution for sustainable management of septage, via a vermifiltration system, in the Republic of Moldova. A technical description of the main components of a demonstration model that was implemented at a household level is presented. The results from the model show an 98.85% reduction of ammonia content, 49,21 % CODMn (an indicator of degradation of easily degradable organic substances) and 85,28% of CODCr (showing degradation of hardly degradable organic substances). Considering the fact that the concentration of ammonium in the effluent was considerable reduced, while that of nitrate nitrogen remained rather low, it was assumed that the activity of earthworms was rather limited, probable the microorganisms, interacting symbiotically and synergistically with earthworms not being well developed in the vermifilter bed. The study suggests that the vermifiltration technology can provide a sustainable wastewater management solution and its application can be promoted in certain settings such as schools and kindergartens in Moldova. However, good insulation should be considered to avoid the freezing problems during winter while the odor nuisance in the septic tank can be reduced by adding lactic acid bacteria can also be applied.

This article presents the scientific results focused on investigating the impact of the ZooBioR remedy, obtained from Spirulina platensis, tested on young hens, in the first technological phase of laying. The research was initiated on young hens, of 24 weeks old, belonging to the “Hy-Line” hybrid, bred in identical conditions of nutrition and maintenance. The hens in the experimental group received daily food supplemented with ZooBioR, in proportion of 10 mg active substance/kg feed. During the study the birds were monitored, and periodically were determined body temperature, frequency of respiratory movements. For haematological investigations, from birds was collected blood from the axial veins and, as the case may be, from the jugular veins, in standard model test tubes. It has been established that the ZooBioR remedy is well tolerated by young hens and exhibits anti-stress and adaptive properties. In addition, the tested product has a positive evolution on the hemogram, increases the natural body resistance, inducing at the end of the study a tendency of increase of platelets in blood.

A pitfall survey of beetles in steppe ecosystems of the Republic of Moldova was conducted. Five locations were investigated, two from the Balti steppe and three from the Bugeac steppe. As a result, a total of 563 beetle specimens, belonging to 98 species, 51 genera, and 15 families were collected. Among families recorded Carabidae was the one with the highest number of species. The ecological features of collected beetle species were revealed. The results show that steppes are still important biodiversity reservoirs within the boundaries of the country and urgent conservation activities are required.

In this study we investigated the communities of soil nematodes in the forest habitats invaded and uninvaded by Fallopia japonica (Houtt.) Ronse Decr., in Tatra National Park, Slovakia. We found that invasion by F. japonica altered nematode communities and their structures. Total nematode abundance, species number and nematode biomass were significantly lower in invaded than uninvaded plots, but species diversity remained unaffected throughout the study. The overall abundance of all nematode trophic groups well represented the negative impact of F. japonica invasion on soil food webs, supported by low values of all maturity indices, a structural index and the Jaccard index of faunal similarity. A weighted faunal analysis similarly characterized the food webs of invaded plots as poorly developed or highly disturbed, with bacterial decomposition and a low C/N ratio. Our findings thus suggest that dense plots of knotweed simplify the structural complexity of the soil environment by reducing the richness of plant species, which may have contributed to the negative changes in the structures of the nematode communities.

Published: October 2021

In the paper is described the mono- and poly-invasions impact on some morpho-functional indices in wild boars. So, in result of the investigation of hematological indices in uninfested mono- and poly-parasitized wild boars, it was established that both the indices of hemoglobin content, of hematocrit, erythrocyte’s number, thrombosis time and ESR (erythrocyte sedimentation rate) vary and are more increased in the I group with uninfested wild boars compared to mono - and poly-parasitized ones. It has been established that at infested boars with S. papillosus from the I group, and in those infested with D. lanceolatum from the II group there is a decrease of hemostatic indices, but their maximum decrease is highlighted in the IV group with wild boars infested with Dicrocoelium lanceolatum, Strongyloides papillosus, Metastrongylus elongatus and Eimeria debliecki. This decrease is due to eliminated exotoxins by parasites, which contain anticoagulants and hemolyzers and which neutralize the fibrinogen, thrombin, Ca+ ions and vitamin K properties from the body.

The results of the complex parasitological studies conducted in the wild birds of hunting interest as well as domestic birds demonstrates that the phenomenon of the poliparasitism is a static one, although the poliparasitic quantitative and qualitative structure is continuously changing. This is due to instantaneous contact of the wild birds with the domestic ones, irregular deparasiting of domestic animals and their crates, reduced areas for animals breading and maintenance that ensures the permanent contact with the wild birds as the infestation source. The findings of the study on the diversity of the ectoparasitic fauna in wild birds from various anthropic biotopes of Moldova revealed that the wild and domestic birds are infested with multiple parasites and that the most identified parasitoses are common for major birds of hunting interest as well as for the domestic birds.

Published: October 2021

In the present paper data on seven rare species of diurnal butterflies (Lepidoptera: Papilionoidea) in the fauna of the “Cobîleni” Natural Reserve (Orhei district) are given. The investigations were carried out during 2012-2020 in different habitats of the Reserve: like forest, forest edge, meadows and calcareous canyons. The species Nymphalis xanthomelas (Esper, 1781) and Papilio machaon (Linnaeus, 1758) are reported as new for the fauna of the “Cobîleni” Natural Reserve. Thus, the number of diurnal butterflies in the fauna of the “Cobîleni” Natural Reserve reached 64 species.

As a result of the conducted research it was established, that the meat quality of hens polyparasitized with malophages (Cuclotogaster heterographus, Eomenacanthus stramineus, Goniocotes gallinae, Goniocotes maculatus, Goniodes dissimilis, Lipeurus caponis, Menopon gallinae, Menacanthus cornutus, Menacanthus pallidulus) fleas (Ceratophylus gallinae, C. hirundinis) and mites (Dermanyssus gallinae, D. hirundinis), then treated with Ectostop T5%, Ectostop P5%, showed a protein content of 20.5±0.20%, a pH of 5.3±0.12 and a moisture content of 65.4±0.21%, these indices reaching the level of the non-infested batch (control). The protein level is low in the meat samples of batch II (untreated infested), constituting 16.22±0.03%, and in batch VII treated with Ivomec chemical preparation 17.02±0.87%. The meat moisture index is characterized by a greater difference for batch II and VII constituting 74.52±0.18% and 70.1±0.05% respectively. The pH assessed in untreated infested and Ivomec-treated hens is alkaline, which will lead to decreased keeping capacity.

A reappraisal of the “East carpathian temperate climate refugium” during the last glacial maximum
Authors:   Institute of Zoology, Republic of Moldova, Croitor Roman
Published: October 2021

The concept of “East Carpathian Refugium” is largely based on reports on temperate-climate species from the Late Paleolithic sites of Moldova. The present report proposes new faunistic data from the key Paleolithic sites of Moldova that question the presence of some temperate species in the East Carpathian Region during the Last Glacial Maximum. The revision of archaeozoological material from Cosăuți did not confirm the presence of Capreolus capreolus and Alces alces in this palaeolithic site. Osteological remains previously ascribed to Cervus elaphus, according to new data, belong to Cervus canadensis and Ovibos moschatus.

The studies were performed in the period 2008-2015 in orchards from the central part of the Republic of Moldova and Bacău County, Romania. In both areas 12 species rodent were registered, of which in central Moldova orchards the species R. norvegicus and P. subterraneus were not registered, while in Bacau orchards the species A. uralensis, M. rossiaemeridionalis and D. nitedula weren’t recorded. In CM orchards the dominant species was M. rossiaemeridionalis with about 30%, followed by A. sylvaticus and A. flavicollis. In BC orchards the dominant species was A. flavicollis with more that 41%, followed by A. sylvaticus and M. arvalis.The analysis of demographic structure in spring period showed a high proportion of reproductive females in all species, being the highest at M. rossiaemeridionalis in CM orchard and in A. flavicollis in BC orchard. The share of young individuals constituted up to 40% depending on the species being the highest at M. rossiaemeridionalis in CM orchard and in A. flavicollis in BC orchard. A significant difference in the area of the individual sectors of M.rossiaemeridionalis males and females in the orchard in summer (t = 3.46) and autumn (t = 3.39) was established, as well as for A. sylvaticus in the spring and summer period (t = 2.06; 2.03), and for A.uralensis in spring and autumn (t = 2.99; 3.44).

Authors:   Institute of Zoology, Republic of Moldova, Paladi Viorica
Published: October 2021

The Republic of Moldova has few wet areas. One of them was designated in the year 2000 with the status of Wetland of International Importance (Ramsar). The ecosystems of lakes and ponds are home to a multitude of bird species. Aquatic and semi-aquatic species make up a major component of the studied sector and consists of 94 species. Thousands of specimens transit the area during spring and autumn migrations; others retreat in the winter to be safe and to feed; the summer guests arrive in the warm period of the year to breed. Out of the total number of aquatic and semi-aquatic birds, 26 species are protected nationally and internationally. During the study period, rare or accidental species were recorded, such as: Bubulcus ibis, Cygnus columbianus, Branta ruficollis, Grus grus, Sterna caspia, Arenaria interpres, Larus ichthyaetus etc.
