Zum Tragverhalten von Suction-Buckets unter zyklisch lateralen Einwirkungen/On the Behaviour of Suction Buckets under Cyclic Lateral Loads
Authors: Tasan H. Ercan
Published: March 2021

Eine sichere und wirtschaftliche Planung von Suction-Bucket-Gründungen für Offshore-Bauwerke erfordert gesicherte Erkenntnisse über das Tragverhalten von Boden-Bucket-Systemen unter zyklischen Einwirkungen. Zyklische Einwirkungen aus Wind und Wellengang können zur Akkumulation von bleibenden Verformungen und Porenwasserüberdrücken in wassergesättigten Böden führen und sind deshalb innerhalb der Tragfähigkeits- und Gebrauchstauglichkeitsnachweise zu berücksichtigen. In diesem Beitrag wird das Tragverhalten eines Boden-Bucket-Systems unter zyklisch lateralen Einwirkungen numerisch untersucht. In den FE-Berechnungen wird zur realistischen Erfassung der Wechselwirkungen zwischen der Struktur, dem wassergesättigten Meeresboden und dem Porenwasser ein Zwei-Phasen-Modell in Verbindung mit einem hypoplastischen Stoffgesetz eingesetzt. Im Mittelpunkt der numerischen Untersuchungen steht die quantitative Ermittlung der Auswirkungen von zyklischen Lastcharakteristiken auf die Akkumulationseffekte. Berechnungen mit zyklischen Schwell- und Wechsellasten zeigen, dass die Akkumulation von bleibenden Verformungen und Porenwasserüberdrücken in wassergesättigten Böden und somit auch das interaktive Tragverhalten des Boden-Bucket-Systems von der zyklischen Lastcharakteristik bedeutend beeinflusst werden.

Published: March 2021

A library of pinane-based 2-amino-1,3-diols, analogues of biologically active sphingosine, was synthesised in a stereoselective manner. Isopinocarveol prepared from (–)-α-pinene was converted to condensed oxazolidin-2-one in two steps by carbamate formation followed by a stereoselective aminohydroxylation process. The relative stereochemistry of the pinane-fused oxazolidin-2-one was determined by 2D NMR and X-ray technics. The regioisomeric spiro-oxazolidin-2-one was prepared in a similar way starting from commercially available (1R)-(–)-myrtenol. Reduction or alkaline hydrolysis of oxazolidines followed by reductive alkylation resulted in primary and secondary 2-amino-1,3-diols, which underwent regioselective ring closure with formaldehyde or benzaldehyde delivering pinane-condensed oxazolidines. During the preparation of 2-phenyliminooxazolidine, an interesting ring–ring tautomerism was observed in CDCl3.

Published: March 2021

Fungal infections are affecting millions of people in the world every year. Severity of infections range from superficial mycoses to more chronic systemic mycoses. As more fungi species evolve, emergence of drug resistant strains is becoming a serious concern to the public health. There is now less number of effective antifungal drugs available in the market for treatment of invasive fungal infections. In an effort to combat this escalating issue, the use of nanoparticles as antifungal agent has been proposed and explored. Versatility of nanoparticles and its unique physico-chemical properties are proven beneficial for developing new therapeutic methods in treatment of fungal infections. Nanoparticles produced from biological synthesis have attracted keen interests from researchers, as they are more environmentally friendly, sustainable, cost-effective, and biocompatible. This mini review will provide an insight on the current antifungal studies and discuss the theory behind mechanism of actions of nanoparticles.

Authors: Treger Iuly , Treger Lena Lutsky
Published: March 2021

The COVID-19 pandemics has dramatically changed the organization of public rehabilitation services around the world. Rehabilitation managers and doctors have faced different challenges at all stages of patient management from acute departments to home, especially in the periphery of the country.
Aim. To analyze and present the regional experience of rehabilitation system reorganization during pandemics.
Materials and methods. The Southern region of Israel is a big part of the country with about one million of population. The Physical Medicine and Rehabilitation department at the Soroka University Hospital is a part of the regional rehabilitation network, and was
forced to find optimal solutions to all kinds of organizational challenges from the first days of the crisis. Most of those solutions, which, in our opinion, showed their effectiveness in managing our patients in this confused situation are presented and discussed in the article.
Results. COVID-19 pandemics crisis had mostly a negative input on the whole system organization. The normal regular flow of multistage rehabilitation process was interrupted, serious part of professional staff was out of system due to quarantine and pandemic restrictions. The whole system was forced to change the management algorithms very quickly, sometimes as an immediate response to everyday changes.
However, some changes that have occurred in response to the changed conditions may have a positive impact on the work of the rehabilitation system in the future and will also be discussed in the article.
Conclusion. Our regional professional situation, of sure, is a combination of local rehabilitation organization and characteristics of Israeli health system, and from that point of view it is quite unique. But the problems of periphery are almost the same in every country so our local experience can help professionals in other regions.

The article presents the results of a study of the biopsychosocial principle in the rehabilitation of patients with breast cancer.
Aim. to assess the need for patients with operable breast cancer in rehabilitation measures at various stages of treatment.
Results. when assessing the need for rehabilitation of patients with operable breast cancer, it was found that the need for rehabilitation measures in all patients increases in the postoperative period and persists for 12 months after the end of treatment. Special attention should be paid to the indicators of physical and social functioning in subgroups of patients who received neoadjuvant chemotherapy: increased fatigue, weight gain, unstable emotional background impose significant restrictions on the socio-role functioning of patients, reducing the quality of life and increasing the risks associated with the progression of the underlying disease, exacerbation of chronic diseases. Thus, patients who participated in the program of rehabilitation measures in the framework of the biopsychosocial approach showed the best performance after the end of treatment during the observation period: in the subgroup of patients receiving
chemotherapy and rehabilitation in the framework of the biopsychosocial model, the dynamics of the recovery needs of the operation sought to average indicators by domain “b4552 Fatigue” – 21%, “b4551 Aerobic capacity “ – 18%, “d240 Handling stress and other psychological demands » – 39%, “b710 Mobility of joint functions “ – 29%, self-service (“d510 Washing”; “ d540 Dressing») – 21%, “b455 Exercise tolerance functions “ – 22%. In the subgroup of patients who received on-demand rehabilitation, there was an increase in the need for rehabilitation by domain: “d240 Handling stress and other psychological demands “ – 45%, “b4552 Fatigue” – 28%, self-service (“d510 Washing”; “ d540 Dressing») – 32%, b455 Exercise tolerance functions – 30%.
Conclusion: The results of the study suggest a positive effect of rehabilitation measures on the functioning of patients with operable breast cancer.

Published: March 2021

The VLITE-Fast experiment combines the wide-field-of-view of single dish antennas operating at low frequency with the high angular resolution furnished by the 3–30 km baselines of the VLA, making it ideal for the detection and precise localization of radio transients. We describe the VLITE-Fast experiment, its capabilities, and operational status, and we briefly overview its main science case, the detection of fast radio bursts (FRBs) and determination of their host galaxies. We report on commissioning observations in an incoherent mode prohibiting precise localization. These include discovery of FRB 20200405A, detected during early science operations at dispersion measure (DM) = 212.3 pc cm−3, strongly in excess of the Galactic DM along the line of sight.

Published: March 2021

With the rapid development of Internet information technology, the advantages of social media in terms of speed, content, form, and effect of communication are becoming increasingly significant. In recent years, more and more researchers have paid attention to the special value and role of social media tools in disaster information emergency management. Weibo is the most widely used Chinese social media tool. To effectively mine and apply the emergency function of disaster situation microblogs, a disaster situation information discovery and collection system capable of online incremental identification and collection are constructed for massive and disordered disaster microblog text streams. First, based on the deep learning- trained word vector model and a large-scale corpus, an unsupervised short-text feature representation method of disaster situation Weibo information is developed. According to the experimental results of the feature combination test and the training set scale test, the SVM algorithm was selected for disaster microblog information classification, which realized effective identification of disaster situation micro-bloggings. Then, the temporal information similarity and geographic information similarity are used to improve the single text similarity algorithm, and a Chinese disaster event online real-time detection model is constructed. Furthermore, the disaster-affected areas can be achieved in real-time based on the detection results. By crawling and classifying the micro-bloggings from the disaster-affected areas, it is possible to realize the incremental identification and collection of online disaster situation Weibo information. Finally, the empirical analysis of disaster events such as the “Leshan Earthquake” shows that the real- time intelligent identification and collection system for disaster situation Weibo micro-bloggings developed in this paper can obtain large-scale and useful data for disaster emergency management, which proving that this system is effective and efficient.

Periodic orbits for double regularization of piecewise smooth systems with a switching manifold of codimension two
Authors: Pi Dingheng
Published: March 2021

In this paper we consider an \begin{document}$ n $\end{document} dimensional piecewise smooth dynamical system. This system has a co-dimension 2 switching manifold \begin{document}$ \Sigma $\end{document} which is an intersection of two hyperplanes \begin{document}$ \Sigma_1 $\end{document} and \begin{document}$ \Sigma_2 $\end{document}. We investigate the relation between periodic orbit of PWS system and periodic orbit of its double regularized system. If this PWS system has an asymptotically stable sliding periodic orbit(including type Ⅰ and type Ⅱ), we establish conditions to ensure that also a double regularization of the given system has a unique, asymptotically stable, periodic orbit in a neighbourhood of \begin{document}$ \gamma $\end{document}, converging to \begin{document}$ \gamma $\end{document} as both of the two regularization parameters go to \begin{document}$ 0 $\end{document} by applying implicit function theorem and geometric singular perturbation theory.
Universities and Place Leadership: a question of agency and alignment
Authors: Fonseca Liliana , Nieth Lisa , Salomaa Maria , Benneworth Paul
Published: March 2021

There is increasing interest in the question of how different stakeholders develop, implement and lead regional upgrading processes with the concept of place leadership emerging as one response to this. Simultaneously, universities face growing expectations that they will contribute to regional development processes – often through their collaborative relationships with other regional stakeholders. But universities are complex in terms of their internal and institutional structures, which undermines their capacities to enact coherent place leadership roles. We seek to understand how strategic leadership in universities can contribute to innovation and regional development in the context of the fundamental institutional complexity of universities. We address this through a qualitative, explorative case study comparing six European regions where universities have sincerely attempted to deliver place leadership roles. We identify that the elements of agency and alignment are vital in that: firstly, university leadership has to align with regional coalitions on the one hand and internal structures on the other hand, and secondly, this leadership must give individuals agency in their regional engagement activities.
Redesigning a First Year Physiology Course using Learning Analytics to Improve Student Performance
Authors: Williams Mark T. , Lluka Lesley Jan , Chunduri Prasad
Published: March 2021

Learning analytics (LA), a fast emerging concept in higher education, is used to understand and optimize the student learning process and the envi-ronment in which it occurs. Knowledge obtained from the LA paradigm is often utilized to construct statistical models aimed at identifying students who are at risk of failing the unit/course, and to subsequently design inter-ventions that are targeted towards improving the course outcomes for these students. In previous studies, models were constructed using a wide variety of variables, but emerging evidence suggests that the models constructed us-ing course-specific variables are more accurate, and provide a better under-standing of the learning context. For our current study, student performance in the various course assessment tasks was used as a basis for the predictive models and future intervention design, as they are conventionally used to evaluate student learning outcomes and the degree to which the various course learning objectives are met. Further, students in our course are pri-marily first-year university students, who are still unfamiliar with the learning and assessment context of higher education, and this prevents them from adequately preparing for the tasks, and consequently reduces their course performance and outcome. We first constructed statistical models that would be used to identify students who are at risk of failing the course and to identify assessment tasks that students in our course find challeng-ing, as a guide for the design of future interventional activities. Every con-structed predictive model had an excellent capacity to discriminate between students who passed the course and those who failed. Analysis revealed that not only at-risk students, but the whole cohort, would benefit from in-terventions improving their conceptual understanding and ability to con-struct high-scoring answers to Short Answer Questions.

Breast cancer is a common cancer in female. Accurate and early detection of breast cancer can play a vital role in treatment. This paper presents and evaluates a thermogram based Computer-Aided Detection (CAD) system for the detection of breast cancer. In this CAD system, the Random Subset Feature Selection (RSFS) algorithm and hybrid of minimum Redundancy Maximum Relevance (mRMR) algorithm and Genetic Algorithm (GA) with RSFS algorithm are utilized for feature selection. In addition, the Support Vector Machine (SVM) and k-Nearest Neighbors (kNN) algorithms are utilized as classifier algorithm. The proposed CAD system is verified using MATLAB 2017 and a dataset that is composed of breast images from 78 patients. The implementation results demonstrate that using RSFS algorithm for feature selection and kNN and SVM algorithms as classifier have accuracy of 85.36% and 75%, and sensitivity of 94.11% and 79.31%, respectively. In addition, using hybrid GA and RSFS algorithm for feature selection and kNN and SVM algorithms as classifier have accuracy of 83.87% and 69.56%, and sensitivity of 96% and 81.81%, respectively, and using hybrid mRMR and RSFS algorithms for feature selection and kNN and SVM algorithms as classifier have accuracy of 77.41% and 73.07%, and sensitivity of 98% and 72.72%, respectively.
Role of transport network accessibility in the spread of COVID-19 - a case study in Savar Upazila, Bangladesh

Published: March 2021

The aim of this research was to test the hypothesis that people in a typical high-transport zone are particularly vulnerable with respect to transmission of coronavirus disease 2019 (COVID-19), a new contagious disease that has rapidly developed into a highrisk global problem. A case study was carried out in Savar Upazila, a sub-district of the capital city Dhaka in Bangladesh, which is traversed by a prominent national highway (Dhaka- Aricha-N5) that also passes the concentric industrial export processing zone surrounding Dhaka. This municipality is thus part of a high-density transport network with extensive economic activities. COVID-19 data were collected from local records at the Upazila Health Complex, while spatial data of the Savar Upazila, including the pertinent road network, were identified and digitized using geographical information systems software. The presence of COVID-19 in in Savar Upazila was found to be strongly associated with the reach and mechanism of transport networks (Pearson correlation = 0.76 with 99% confidence interval).
Economic contestation over user fees in low-resourced healthcare systems: A literature review
Authors: Pagiwa Vincent
Published: March 2021

This paper reviewed the literature on economic theory and assumptions that provide the rationale for using a price system to finance health care services in developing countries. The primary case in favor of a system of user fees for financing healthcare in these countries lies in allocative efficiency results to be achieved through a price system. The assumption being that, the price system signals to consumers what they must pay for health care services hence giving them an incentive to utilize those services well. However, this assumes perfect markets, where prices reflect the true marginal benefits of consuming healthcare goods and the marginal cost of their production. All equity concerns being addressed through price discrimination, a system of user fees can then allocate health care resources efficiently. Although the application of user fees in the health sector is justified by the perfect markets, there are concerns that a perfect market is less likely to be the case in health sector. Therefore, it will not be a viable way to rely on the price system to allocate resources to the population when markets of any healthcare goods and services are not available or are imperfect. Information asymmetry and uncertainty are the major obstacles to a proper function of a price system in healthcare service provision. Due to the inelastic nature of the demand for healthcare, charging fees for healthcare services can pose hard financial catastrophes to poor and lead into poverty. This suggests the need to establish healthfinancing policies that would facilitate the creation of new markets or which can improve the performance of existing ones in developing countries.

In this paper presents data of researches about fiber length in the 4-5 species. The largest number of plants with the indicated analyzed trait in hybrid combinations, obtained with the participation of the variety Omad, appeared with a number of variations in fiber length at 35,0-36,0 mm and above. Investigation of 4-species hybrids of F2 and back cross hybridization allowed some improvement in the average value of trait when compared with F1. Despite the emergence of transgressive plants with fiber length 36,1-37,0 mm and above, the average trait of composite 5 species hybrids F2 remained almost at the level of F1, i.e. 35.5-36.0 mm. The greatest number of positive recombinants occurred in 5 species back crossing developed with the participation of Termez-31.

Published: March 2021

Planting pattern and sowing date are the eminent factors affecting plant growth and development. The two-year experiment under field conditions was conducted as split plot design in three replications during 2017 and 2018. The main plot was planting pattern in two levels (PP1: one-row, and PP2: two-row plantation pattern) and subplot was sowing date in three levels (SD1: June 15, SD2: June 30 and SD3: July 15). The results revealed that the biological yield in SD2 had significant increase by 14% and 6% in comparison to SD1 and SD3 under two-row plantation pattern in the first year respectively. In PP2, the seed yield was improved by 19% and 15% compared to SD1 and SD3 at SD2 in 2017. Carbohydrate content varied in the two years. In mono row plantation method, the grain carbohydrate content was higher in SD1 significantly. In bean plants under PP2, protein content on SD2 increased by 13% compared to SD3 in the second year of experiments. The greatest amount of essential amino acids was found in leucine followed by lysine, arginine, phenylalanine, valine, isoleucine, histidine, and threonine. We found that the concentration of essential amino acid in tepary bean grains was significantly changed by sowing date. We suggest that in tepary bean cultivation the use of plantation pattern is very effectiveness and two-row plantation pattern was the most important when the sown date delayed by late of June under same experimental environment.

Published: March 2021

Some species of Cnidarians, well known venomous organisms, are able to induce serious health problems as well as economic and social trouble. A lot of data show that cnidarian venoms can be cytotoxic to cultured cells. Therefore, a priority of the research is to find tools which could counteract the damaging activity of venoms. In this connection, the modulatory effects exerted by extracts of plants Ananas comosus (L.) and Carica papaya (L.) on cytotoxicity of heterotrichous microbasic eurytele nematocysts isolated from the jellyfish Pelagia noctiluca was evaluated. The nematocyst extract induced strong cytotoxicity at highest tested doses with reduction of cell survival below 40% and IC50 value of 40×103 nematocysts/mL. Both plant extracts significantly improved the survival of cells, so that the IC50 resulted 74×103 and 100×103 nematocysts/mL in the presence of A. comosus and C. papaya extracts, respectively, both used at 10 and 100 μg/mL. Taking into account that heterotrichous microbasic eurytele nematocysts are present mainly in tentacles, which Pelagia noctiluca utilizes both for predation and defence, this result is particularly interesting from both ecological and sanitary point of view and demonstrates the potential of these plants extracts against cnidarian venoms.

The present study aimed to evaluate the phytochemicals and the antidiabetic properties of Origanum floribundum aqueous extract. Phytochemical screening was conducted by using various standard procedures. Acute toxicity of the extract was determined by OECD guidelines 423. The antidiabetic activity of the plant was determined by alloxan-induced diabetes in Wistar albino rats. Data obtained showed the detection of various secondary metabolites such as alkaloids, flavonoids, saponins, terpenoids in the extract. No mortality was observed during acute toxicity studies up to the dose of 2000 mg/kg. The aqueous extract presented the ability of reducing blood glucose levels. These findings indicated that Origanum floribundum aqueous extract had various phytopharmacological activities and thus it would be useful to isolate and characterize the compounds responsible for these bioactivities in the future.

Development of natural immunostimulants as dietary additive keeps receiving scientist’s interest and administration of ethanol extract of additive is one of the effective methods to concentrate their bioactive compounds to improve their effects. Dietary inclusion effect of ethanol extracts of yacon and ginger on growth, feed utilization, body composition, plasma chemistry of fish and challenge test against Vibrio anguillarum compared to a commercial probiotic (Super lacto®) was determined. Three hundred and sixty juvenile fish were distributed into 12, 50 L flowthrough tanks. Four experimental diets were prepared. Additive-free basal diet was served as the control (CON) diet. The 1% ethanol extracts of yacon and ginger, and 0.5% Super lacto® were included into the CON diet, referred to as the YCE, GGE and SUP diets, respectively. Each diet was hand-fed to triplicate groups of fish for 8 weeks. After the 8-week feeding trial, fish were injected with V. anguillarum and survival was monitored for the next 7 days. Dietary additives did not affect weight gain, feed utilization, whole body composition and plasma parameters of fish. Survival of fish fed the YCE and GGE diets was significantly higher than that of the fish fed the CON and SUP diets at the end of the 7-day post observation. Ethanol extracts of yacon and ginger can be effectively used as natural immunostimulants for olive flounder at occurrence of V. anguillarum.

Published: March 2021

Western Cameroon is one of the regions most in needs of innovative and healthy solutions for freshwater fish conservation. This study aimed at evaluating the socio-economical characteristics of fish smokers and technical factors on the species smoked in the Noun Division. A total of 91 fish smokers were chosen. The socio-economic data were on age, gender, religion, number of dependents, marital status, ethnic group, education level, economic activities, smoking goals and workforce. The results of this study showed that fish smoking is practiced mainly by women (70%) which is common in Sub Sahara Africa small scale fish sector. The smokers are aged from 20 to 50 years (80%), married (92.2%) and taking care of a family of 1 to 10 persons (80%). These smokers are Muslim (74%), belonging to the Bamoun ethnic group (81%). They were also involved in other activities: agriculture (29%) and trade (1%). About 67% of the sampled smokers’ population had an experience of more than 10 years in the domain. The Purpose of smoking was largely sales (97%) and subsistence (3%). Nile tilapia (Oreochromis niloticus) was the most smoked species (36%), followed by African catfish (Clarias gariepinus) with a proportion of 32%. The average quantity of fresh fish smoked was 110 kg/day/smoker, with Oreochromis niloticus being more produced (60±4.74 kg/day/smoker). With regard to the smoking techniques used, hygiene measures were poorly respected. The major constraints revealed by the survey were that freshwater’s traditional fish smoking activities in Noun Division are influenced by gender, economic and cultural background. There is a lack of technical support material and financial means. Any implications for future investigations on health and food safety will be suitable for fresh fish smokers and the entire consumers.

A cross sectional quantitative survey that obtained information on high risk behaviours which expose individuals to sexually transmitted infections (STIs) especially HIV was carried out in Lake Chad Basin of Borno among 1,790 volunteers. A well-structured questionnaire was developed and used to collect the desired baseline sociodemographic characteristics by direct interview of respondents in their houses among the populations living in the ordinary households, the mobile population and vulnerable population group (VPG) not living in the households were interviewed in their places of abode with discretion. The mean age range of the participants was 32.5 years (SD + 2.21) ranging from 15 to 49 years. 1,234 (68.9%) of the respondents were males while 556 (31.1%) were females. The prison inmates had the highest prevalence of STIs, 37% of the respondents didn’t know that they were at risk of contracting HIV. The knowledge of HIV status was higher among the males (80.2%) than the females (19.3%). The use of male and female condom was higher among the rural (19.2%) than the urban (10.8%) respondents. This study revealed high risk practices among the respondents even though there is tremendous HIV test intake across both the general and vulnerable populations, there is need for more awareness as rate of risk perception is very low.
A new Weibull Exponentiated Inverted Weibull Distribution for modelling positively-skewed data

An Exponentiated Inverted Weibull Distribution (EIWD) has a hazard rate (failure rate) function that is unimodal, thus making it less efficient for modeling data with an increasing failure rate (IFR). Hence, the need to generalize the EIWD in order to obtain a distribution that will be proficient in modeling these types of dataset (data with an increasing failure rate). This paper therefore, extends the EIWD in order to obtain Weibull Exponentiated Inverted Weibull (WEIW) distribution using the Weibull-Generator technique. Some of the properties investigated include the mean, variance, median, moments, quantile and moment generating functions. The explicit expressions were derived for the order statistics and hazard/failure rate function. The estimation of parameters was derived using the maximum likelihood method. The developed model was applied to a real-life dataset and compared with some existing competing lifetime distributions. The result revealed that the (WEIW) distribution provided a better fit to the real life dataset than the existing Weibull/Exponential family distributions.
Vascularised fibular graft in the management of non-union of fracture shaft of radius: a less ventured entity
Authors: K. Panigrahi Tapas , C. Maharaj Ramesh , P. Nanda Debi
Published: March 2021

Introduction: Non-union of the radius and ulna is a major complication of forearm fractures, accounting upto 10% of all forearm fractures. Multiple modalities are available for the treatment of non-union. Vascular grafts are a less sought-after surgical choice owing to the need of expertise and skills of surgeons. We discuss a case of gap non-union of fracture shaft radius treated with vascular fibula graft.

Case Report: We describe a case of 45yr old lady with closed fracture of both bones of left forearm. She underwent open reduction and internal fixation with 3.5 small DCP (6 hole) two days following trauma. On subsequent follow up in 6 months the radius fracture showed signs of infected non-union with osteolysis at screw sites while the ulnar side showed signs of satisfactory union. The patient underwent debridement with implant removal and osteosynthesis with vascularised fibula for gap non-union as second stage. 3 and 6 months follow up showed improvement in DASH score as well as VAS score and fair return of regular activity.

Conclusion: In management of gap non-union of Shaft radius with gap (>6cm) vascularised fibular graft provides excellent functional outcome with far less donor site complications.
