Published: July 2020

We present multiepoch infrared photometry and spectroscopy obtained with warm Spitzer, Subaru, and the Stratospheric Observatory for Infrared Astronomy to assess variability for the young (∼20 Myr) and dusty debris systems around HD 172555 and HD 113766A. No variations (within 0.5%) were found for the former at either 3.6 or 4.5 μm, while significant nonperiodic variations (peak to peak of ∼10%–15% relative to the primary star) were detected for the latter. Relative to the Spitzer Infrared Spectrograph spectra taken in 2004, multiepoch mid-infrared spectra reveal no change in either the shape of the prominent 10 μm solid-state features or the overall flux levels (no more than 20%) for both systems, corroborating the fact that the population of submicron-size grains that produce the pronounced solid-state features is stable over a decadal timescale. We suggest that these submicron-size grains were initially generated in an optically thick clump of debris of millimeter-size vapor condensates resulting from a recent violent impact between large asteroidal or planetary bodies. Because of the shielding from the stellar photons provided by this clump, intense collisions led to an overproduction of fine grains that would otherwise be ejected from the system by radiation pressure. As the clump is sheared by its orbital motion and becomes optically thin, a population of very fine grains could remain in stable orbits until Poynting–Robertson drag slowly spirals them into the star. We further suggest that the 3–5 μm disk variation around HD 113766A is consistent with a clump/arc of such fine grains on a modestly eccentric orbit in its terrestrial zone.

We are facing serious coronavirus disease-19 pandemic, caused by the severe acute respiratory syndrome coronavirus-2. Among infected individuals, there is a higher prevalence of the cardiovascular disease, which leads to their poor prognosis. Myocardial injury is present in more than 15% of critical ill patients in the form of acute myocardial dysfunction or subsequent myocardial injury that develops as disease severity. This new virus pandemic is a global challenge for health-care system which was we still have much to learn.

Authors: Paramita Swandari , Rahmadi Anton , Isnuwardana Ronny , Nugroho Rudy Agung
Published: July 2020

BACKGROUND: East Kalimantan, Indonesia, will play a significant geopolitical role as the province has been selected as the location of the future capital city of Indonesia. As a buffer zone to the capital city, there is urgent attention on the preparedness of the cities and regencies in East Kalimantan to respond to emergent infectious disease events such as coronavirus disease-19 (COVID-19).
AIM: The aim of the present study was to descriptively convey information about COVID-19 cases in East Kalimantan during the period of March 18, 2020–April 18, 2020, in terms of the isolation, testing, and tracing mechanisms used.
METHODS: The initial distribution of COVID-19 was identified in 5 of 10 districts and is now present in almost all districts except for one very remote regency.
RESULTS: The tracing performance of the fast response teams in East Kalimantan during this period was considered satisfactory with a mean of 0.7% of people under observation testing positive for severe acute respiratory syndrome coronavirus 2, and a mean of 14.4% patients under investigations testing positive. The use of rapid tests since March 30, 2020 has improved the detection ability, with confirmed positive cases as a percentage of confirmed negatives increasing from 20.2% to 31.8%. The use of the COVID-19 rapid test was cross-checked with a dengue rapid test to prevent false-positive identification. Confirmed clusters were announced to the public, urging people to respond and report.
CONCLUSION: The 1-month progress of COVID-19 cases in East Kalimantan showed a total case fatality rate (CFR) of 1.85%, a closed CFR of 8.3% and a closed case recovery rate of 91.7%.

Published: July 2020

Females and males reared from pupae, their pupal exuviae and cocoons, and mature larvae of the Simulium (Gomphostilbia) asakoae species group from various localities in Thailand were morphologically examined. A total of 25 species was identified, including two of four known species (Simulium asakoae Takaoka & Davies and S. chiangdaoense Takaoka & Srisuka), one newly confirmed species (S. myanmarense Takaoka, Srisuka & Saeung, originally described from Myanmar), one newly transferred species (S. inthanonense Takaoka & Suzuki formerly of the S. ceylonicum species group), and 21 new species. Descriptions of all 21 new species are given, and the first full description of the male of S. inthanonense, together with the revised descriptions of its female, pupa, and larva, is also provided. Keys to identify all 27 members of this species group from Thailand are given for females, males, pupae, and larvae. The genetic relationships of all but one species were resolved using COI gene sequence-based analysis. All 26 species were divided into nine subgroups, I–IX, each consisting of two, one, four, nine, one, three, two, one and three species, respectively.
Massification et financement public de l’enseignement supérieur en Haïti : problèmes et défis
Authors: Jacob Sergot
Published: July 2020

L’enseignement supérieur haïtien est en pleine mutation, mais est peu étudié. Cet article examine les conditions dans lesquelles la massification s’y est opérée récemment, d’une part ; et l’ampleur de l’inadéquation du financement public depuis les années 1980, d’autre part. Il met en évidence que malgré la massification, plus rapide, de l’offre pour desservir une demande sociale également en forte hausse, le maigre financement public (en moyenne : 0.33 % du produit intérieur brut (PIB) ; 1.17 % du budget de l’État) consacré au financement des universités publiques, au cours des 30 dernières années, freine leur développement. Dans les faits, malgré l’augmentation, somme toute modeste, du budget des universités publiques par rapport au budget de l’État, la massification s’est traduite in fine dans une réduction de la dépense par étudiant, ce qui n’aide pas à créer les conditions d’un enseignement de qualité acceptable et prive le secteur de sa capacité à jouer un rôle effectif dans le processus de développement socio-économique du pays en se mettant d’abord en capacité de réfléchir sur les problèmes de la société et de son évolution. Remarques à l’intention des praticiens Le système de quasi-gratuité des études, financé par le contribuable, a atteint ses limites, tandis que des mécanismes institutionnels de régulation de la massification sont essentiels pour protéger le consommateur et contrer la baisse de la qualité des formations. Pour mieux positionner le pays sur l’échiquier mondial et profiter des externalités positives de l’éducation supérieure, davantage de ressources publiques doivent y être investies. L’enjeu est alors triple ; car il faut trouver les modalités, nécessairement différenciées, de financement des universités et des études elles-mêmes ; et aussi de diversification de ces financements face aux ressources limitées de l’État.

Authors: Çelik Selcen , Ocak Osman Bulut , İnal Aslı , Aygıt Ebru Demet , Gürez Ceren , Hüseyinhan Zahid , Gökyiğit Birsen
Published: July 2020

Purpose:

To determine the factors affecting the risk of deterioration and evaluate the refractive error change in patients with fully accommodative esotropia.

Methods:

Patients diagnosed as having fully accommodative esotropia (esotropic deviation that started before 7 years of age and less than 8 to 10 prism diopters [PD] of esotropia with full hyperopic correction and/or bifocals) were included in this retrospective population-based cohort study. Refractive error changes were recorded. For comparisons, patients were divided into two groups: nondecompensated fully accommodative esotropia group and decompensated fully accommodative esotropia group.

Results:

Two hundred and twenty-three patients met the inclusion criteria. The mean follow-up time was 5.94 ± 0.31 years (range: 5 to 8 years). The changes in spherical equivalent in the younger than 7 years, 7 to 12 years, and 12 to 17 years groups were statistically significant (
P
< .001). The decrease of hypermetropia was 0.13 diopters/year between 7 and 12 years and 0.06 diopters/year between 12 and 17 years. Forty-one of 223 patients (18.4%) discontinued spectacle therapy during the follow-up period. Hyperopic error and presence of amblyopia were lower, whereas visual acuity level and presence of near-distance disparity were higher in the spectacle discontinuation group (
P
< .001, .007, .01, and 0.01, respectively). Deterioration of fully accommodative esotropia occurred in 30 of 223 patients (13.5%). Boys were more likely to require strabismus surgery (
P
= .32). The mean age at presentation, esotropia angle with and without refractive correction at both near and distance fixation, near distance disparity, and inferior oblique overaction were significantly higher in patients with decompensated fully accommodative esotropia.

Conclusions:

Hyperopic error increased from the initial level until 7 years of age, followed by a myopic shift thereafter. Few children had resolution of fully accommodative esotropia and could discontinue spectacle therapy. Children with male gender, higher esotropia angle, older age at presentation, near-distance disparity, and inferior oblique overaction experienced a greater deterioration of the fully accommodative esotropia.

New records of seaweeds and filamentous cyanobacteria from Trindade Island: an updated checklist to support conservation guidelines and monitoring of environmental changes in the southern Atlantic archipelagos
Authors: Pellizzari Franciane , Sayuri Osaki Vanessa , Santos-Silva Michelle C.
Published: July 2020

Oceanic islands are natural laboratories for investigating species diversity and richness patterns. Changes in abiotic parameters may induce shifts in marine biota. Seaweeds are recognized as bioindicators, though those from remote tropical islands have been rarely studied. This study updates the diversity, richness and distribution of macroalgae from Trindade, a Brazilian volcanic island located 1140 km off the coast. Biotic data, obtained in a global database and in situ and compiled in a new records list, were associated with abiotic parameters. Conservation and ecological issues were discussed in the context of the observed greater richness, expansion of the distributional range and low endemism. A total of 141 species were identified, including 60 new records and 20 taxa of filamentous cyanobacteria. The greater richness, including potential cryptogenic species, may primarily be associated with past incomplete samplings, current new techniques and combined taxonomical methods, including molecular analysis for cryptic species. However, on the macroscale, this study provides information for the re-evaluation of aspects of endemism, connections and biogeographical distribution shifts of seaweed as­semblages, considering environmental changes. In addition, this updated checklist establishes a baseline for further compara­tive studies, reinforcing the hypothesis that biogeographical isolation can be disrupted by meteorological and oceanographic shifts, altering dispersal patterns and resulting in higher ecosystems connectivity.
Difficulties and Performance in Mathematics Competences: Solving Problems with Derivatives
Authors: Díaz Quezada Verónica
Published: July 2020

The objectives of this research are to assess the performance of engineering stu-dents when using mathematical competences to solve problems with derivatives, to analyze their difficulties, and to observe which secondary school contents are essential for this purpose. The study is descriptive and exploratory with the use of quantitative methods. The participants are students of three competence-based engineering programs of a Chilean University. The results show a limited knowledge of secondary education mathematical contents like algebra, the main mathematical functions, and proportional geometry. The presence of difficulties associated to mathematical thinking processes and the complexity of mathematical objects are also evident. However, everyday problems in an artificial or fantasy context were more appealing for students, who solved most of them correctly. Even though these problems are imaginary, they were formulated using situations that engineering students face every day.

Authors: Arinta Rania Rizki , Suyoto Suyoto , Emanuel Andi Wahju Rahardjo
Published: July 2020

Natural disasters are something that is not easy to predict, and one of them is a flood. It is found that the frequency of floods that have occurred in Indonesia is 505 times the total of 1824 natural disasters. Disaster risk reduction is the concept of how people minimise accidents and victims affected by disasters. One example of disaster risk reduction is to provide knowledge to the public about disaster evacuation and prevention before an emergency occurs. The objective of this study is to utilise gamification to increase user effectiveness. The method of gamification is the science used to learn, along with the increasing interest in learning. Gamification is applicable in several fields; one of them is crisis management and emergency training. The gamification is applied by utilising mechanical games, dynamic games, and gamification elements. The results showed that gamification could increase the effectiveness in terms of time by 89.77% of information and education about disaster risk and disaster preparedness to the public. This re-search was conducted at the disaster preparedness participant school with 65 participants, along with 21 communities affected by the flood disaster. Based evaluations on aspects of usefulness (UU), Ease of use (EU), Ease of learning (UL), and satisfaction (US) aspects of usefulness have the highest value because with the application the participant feels helped and can learn the dangers of disaster and preparation for disaster.

Published: July 2020

In this study, we investigated users' subjective attitudes (e.g., acceptance and perceived ease of use) towards artificial intelligence (AI) recommendation services and compared them with human expert recommendation services before and after use. Our experiments used fashion street snaps and online product images. The obtained experimental results indicated that the acceptance of the human expert recommendation service was higher than that of the AI recommendation service before use; however, they were similar after use in the case of both fashion street snaps and online product images. Furthermore, the perceived trustworthiness and perceived expertise of the AI and human expert recommendation services were also the same. In terms of ease of use, the AI recommendation service was perceived to be easier to use than the human expert recommendation service.
Impact of Managers on Agricultural Business Success
Authors: Negrão Carla Sofia Vicente
Published: July 2020

In an increasingly digital environment, it becomes a challenge for agricultural managers to achieve success, whether the enterprise uses e-business or not. The aim of this research is to analyze the impact of manager characteristics on the agricultural business success in Portugal. The sample consists of 393 agricultural enterprises. Hierarchical multiple regression was performed. The results suggest that increasing the age of agricultural managers reduces the agricultural business success. Furthermore, managers with university and primary education appear more motivated to success than the managers with secondary education. The joint effect of age and education is significant only when the enterprises use e-business. In this case, when managers have primary education, the aging of the manager translates into greater growth comparatively the one that has secondary education. University education of the manager provides less growth than when they have the secondary education.

Published: July 2020

The micro-drill is one of the manufacturing processes that is developing, especially in the electronics, aerospace, pharmaceutical, and automotive industries. This paper describes the results of the high-speed microdrill process in stainless steel. The drilling process is used to make the micro screen. The cutting tool material is tungsten carbide with a diameter of 0.2 mm. Drilling holes arranged in a honeycomb configuration. The machining parameters used are spindle speed of 20,000 rpm, 22,000 rpm, 24,000 rpm, and feed rate of 1 mm/min, 1.5 mm/min, 2 mm/min. Micro-drilling holes are visually analyzed using a Scanning Electron Microscope (SEM) to measure the accuracy of the hole dimensions. The results of the machining process found that the most significant deviation of the hole dimension size with a value of 0.276 mm occurred at a spindle speed of 20,000 rpm with a feed of 1 mm/min. While the deviation of the smallest hole size with a value of 0.2019 mm occurred at a spindle speed of 24,000 rpm with a feed of 2 mm/min, these results conclude that the accuracy of the hole dimensions will increase in proportion to the increase in spindle speed and feeding.

Authors: Putra Teuku Edisah , Husaini  , Prakasa Hary , Hasanuddin Iskandar , Rizal Muhammad , Machmud Muhammad Nizar
Published: July 2020

This study examines the fatigue life of the SAE 5160 carbon steel as the material for an automotive coil spring subjected to road strain. The strain signals were acquired by attaching a strain gauge on the component, driving a car up- and down-hill roads. The results of the fatigue life assessment based on the strain-life approach show that the downhill road resulted in a lifespan of 15,000 cycles to failure, which was 53% lower than the uphill road. This value was a result of braking when the vehicle is moving downhill, causing stress to the component leading to shorter fatigue life.

Authors: Putra Teuku Edisah , Husaini  , Ikbal Muhammad , Hasanuddin Iskandar , Rizal Muhammad , Machmud Muhammad Nizar
Published: July 2020

The purpose of this work was to predict the fatigue life of the AISI 1513 carbon steel due to the strains measured at a vehicle's lower arm. The strain signals were acquired using a strain gauge installed at the lower arm, and then the car was driven at various road surfaces. On the smooth road surface, the car was driven at a speed of > 70 km/h and on the rough road surface, at a speed of < 20 km/h. The results show that when the vehicle was driven on the rough road, the lower arm received higher stress, which provided a shorter fatigue life. The contour of the road surfaces provided a vertical load, directly working the lower arm and reducing the load vertically. The fatigue life for the rough road surface was 13,050 cycles to failure. This value was 91,195% lower than the fatigue life on the smooth road surface.
A Novel Method for Analyzing Pore Size Distribution of Complex Geometry Shaped Porous Shale
Authors: Ming Yang , Mian Lin
Published: July 2020

This article proposes the differential BJH equation based on the principles of multilayer adsorption and capillary condensation, which was simplified by theoretical investigation and experiments. This work indicates that the differential function of isotherm and the differential function of pore size to relative pressure determine the pore size distribution of porous media. The differential BJH model can be used to explain the source of the false peak in pore size distribution and to calculate the pore size distribution of different shapes of pores in a porous media with a porous structure. It has an excellent application prospect in the characterization of complex pore structure represented by shale.

Identifying the role of agricultural extension services in improving technical efficiency in the paddy farming sector in Sri Lanka
Authors: Athukorala Wasantha
Published: July 2020

The overall aim of this study is to identify the role of agricultural extension services in improving technical efficiency in the rice farming sector in Sri Lanka. Accordingly, the study attempts to investigate how the agricultural extension service received by the farmers can improve technical efficiency (TE), using 200 farm-level data points in Ampara district in Sri Lanka. The Stochastic Production Frontier approach is used to estimate technical efficiency. Results show that the mean TE of rice farming in the study area is 0.61, although 54 % of rice farmers exceeded this average. This indicates that there is scope to further increase the output by 39 percent without increasing the level of input. It is also found that the contribution of the agricultural officers on increasing technical efficiency level is approximately 13 percent. This implies that production of paddy could be increased significantly by increasing the role of agricultural officers in the country. The overall findings of this research will help implement policies to increase the technical efficiency which is increasingly posing a major impediment to agricultural growth, environmental protection and sustainable development in any country.
Compression Wrapping for Acute Closed Extremity Joint Injuries: A Systematic Review
Authors: Borra Vere , Berry David C. , Zideman David , Singletary Eunice , De Buck Emmy
Published: July 2020

Objective

Current prehospital recommendations for an acute closed extremity joint injury (ACEJI) are to apply compression in some manner. However, the effectiveness of compression is unclear. We performed a systematic review to summarize and synthesize the evidence for the use of a compression bandage for ACEJI in the prehospital setting.

Data Sources

Cochrane Library, PubMed, and Embase were searched for relevant literature in November 2019.

Study Selection

Controlled trials involving adults in the prehospital setting with a recent ACEJI were included when compressive, nonimmobilizing interventions, feasible in a first aid setting, were applied and compared with no compression or any noncompressive intervention, such as braces, splints, or noncompressive stockings. Articles in all languages were included if an English abstract was available.

Data Extraction

Data on study design, study population, intervention, outcome measures, and methodologic quality were extracted from each included article.

Data Synthesis

Eight studies out of 1193 possibly relevant articles were included. All authors examined compression in the treatment of acute ankle sprains; no studies involved compression for the treatment of other ACEJIs. No difference in the major outcomes of pain reduction or swelling, ankle-joint function, or range of motion could be demonstrated. For the outcome of recovery time, no benefit was shown when comparing compression with no compression. Evidence was insufficient to inform a conclusion about the outcomes of time to return to work or sport. All evidence was of low to very low certainty.

Conclusions

The evidence for the use of a compression wrap was limited to patients with closed ankle injuries. In this systematic review, we could not demonstrate either a beneficial or harmful effect from the application of a compression or elastic bandage compared with no compression or a noncompressive stocking, splint, or brace as a first aid treatment in the prehospital environment.
Closed-Reduction Techniques for Glenohumeral-, Patellofemoral-, and Interphalangeal-Joint Dislocations
Authors: Wright Cynthia J. , Brandon Barbara A. , Reisman Edward J.
Published: July 2020

Joint dislocations account for a small but important portion of all athletic injuries, with most occurring at the glenohumeral, patellofemoral, and interphalangeal joints. Athletic trainers are responsible for managing acute joint-dislocation injuries, which may include performing closed-reduction techniques when appropriate. To achieve optimal patient outcomes, the clinician should be formally trained and skilled in performing various techniques and familiar with the evidence supporting the selection of each technique. In this clinical review, we outline general reduction procedures and then summarize and synthesize the existing literature on common closed-reduction techniques for glenohumeral-, patellofemoral-, and interphalangeal-joint dislocations. When appropriate, the content has been adapted to be specific to the athletic trainer's scope of practice.

Impact of asymmetrical phenomena on asynchronous
three-phase motors in operation mode
Authors: Do Y Nhu , Le Thanh Xuan , Nguyen Ninh Bao , Ngo Tuan Thanh ,   Faculty of Electro-MechanicsHanoi University of Mining and Geology
Published: July 2020

The general theory of three-phase motors is often built based on the
assumption that the three phases voltage is symmetrical. However, in
practice, this operation mode of the motor cannot be achieved due to a
number of reasons such as the structure of the motor is not symmetrical,
the load in the electrical system is not balanced. The asymmetry of threephase
voltage greatly affects the operation mode of a three-phase
asynchronous motor. The most serious affections are: decrease the
starting torque, increase stator current and rotor current, vibration inside
the motor. This affection will reduce the effective operation of the motor.
The paper investigates the effect of asymmetry voltage on the normal
operation mode of a three-phase asynchronous motor based on the
electromagnetic transforming method of electric machines and
simulating on Matlab-Simulink.

Published: July 2020

Consumers are aware of the dangers arising from the use of synthetic antioxidants and antimicrobials in the agrifood industry, demanding safer and “greener” alternatives. In this study, the antioxidant activity of commercial essential oils through DPPH method, their antimicrobial effects against the bacterium Pseudomonas syringae and the phytopathogenic fungus Fusarium oxysporum by means of the standardized disk method were determined. Clove along with winter savory, cinnamon and oregano essential oils as well as carvacrol showed the highest antioxidant activity comparable to reference standards. Wintergreen essential oil was the most potent inhibitor against P. syringae growth at the highest doses (20 and 10 ?L). Oregano essential oil and its main component carvacrol were able to stop the bacterium growth even at the lowest treatment (1 ?L). Cinnamon, oregano and peppermint essential oils inhibited F. oxysporum development at all doses (20, 10 and 5 ?L) assayed. In general, most of the essential oils displayed more antifungal than antibacterial and antioxidant activities.

U xơ cơ tử cung là một trong những bệnh lý phụ khoa phổ biến ở phụ nữ trong độ tuổi sinh sản. Tỷ lệ mắc bệnh khoảng 20 đến 40% dân số, nhưng tỷ lệ lưu hành thật sự có thể thấp hơn chủ yếu là do khối u không có triệu chứng trong phần lớn các trường hợp. U xơ cơ tử cung là dạng phổ biến nhất của khối u tử cung lành tính. UXTC là khối u đơn dòng của cơ trơn tử cung, bao gồm lượng lớn chất ngoại bào (extracelluar matrix) chứa collagen, fibronectin và proteoglycans. Triệu chứng của u xơ cơ tử cung bao gồm chảy máu tử cung bất thường, các triệu chứng chèn ép vùng chậu, vô sinh và các biến chứng sản khoa. Khuyến cáo xử trí u xơ cơ tử cung có triệu chứng là phải cá thể hoá điều trị dựa trên vấn đề chủ chứ không phải giải quyết khối u. Chiến lược xử trí hiện tại chủ yếu liên quan đến can thiệp phẫu thuật, tuy nhiên nhờ vào các tiến bộ trong hiểu biết về sinh bệnh học của u xơ cơ tử cung cũng như mong muốn bảo tồn khả năng sinh sản mà hiện nay điều trị nội khoa dần tỏ ra ưu thế hơn. Bài tổng quan này tập hợp các phương pháp xử trí u xơ cơ tử cung dựa trên bằng chứng đề cập các chiến lược mới cho việc kiểm soát u xơ cơ tử cung.

Mục tiêu: Nghiên cứu được thực hiện nhằm mục đích tìm hiểu một số yếu tố liên quan đến chỉ số phân mảnh DNA tinh trùng.

Phương pháp: Nghiên cứu tiến hành tại Trung tâm Nội tiết sinh sản và Vô sinh - Bệnh viện Đại học Y Dược Huế, trên những trường hợp nam giới các cặp vợ chồng vô sinh đồng ý tham gia vào nghiên cứu. Tiến hành thu thập thông tin hành chính, tiền sử bệnh tật, thói quen sử dụng thuốc lá, rượu bia; thăm khám lâm sàng và cận lâm sàng bao gồm phân tích tinh dịch và xét nghiệm phân mảnh DNA tinh trùng bằng phương pháp SDC. Dựa vào chỉ số phân mảnh DNA tinh trùng (DFI) chia thành 2 nhóm: DFI ≥ 30% và DFI < 30%, phân tích tìm mối liên quan giữa DFI và các yếu tố: tuổi, hút thuốc lá, rượu bia và các thông số mật độ, di động tiến tới, bất thường hình thái, bất thường đầu và cổ - đuôi trong phân tích tinh dịch.

Kết quả: Có 390 người đàn ông trong các cặp vợ chồng vô sinh đầy đủ các tiêu chuẩn được lựa chọn vào mẫu nghiên cứu. Không có mối tương quan nào giữa DFI với tuổi, sức sống và bất thường đuôi - cổ của tinh trùng. Trong khi đó, có mối tương quan thuận của DFI với bất thường hình thái tinh trùng đặc biệt là bất thường đầu và mối tương quan nghịch của DFI với mật độ và di động tiến tới (p < 0,05).

Kết luận: Ngoài phân tích tinh dịch là xét nghiệm tiêu chuẩn để đánh giá chất lượng tinh trùng ở nam giới hiếm muộn, xét nghiệm chỉ số phân mảnh DNA tinh trùng cho thấy vai trò bổ sung cho chẩn đoán vô sinh nam.

Published: July 2020

The epidemiological implications of fresh water snails have continued to pose serious challenge to schistosomiasis control. A survey was conducted to ascertain the species diversity and abundance of aquatic snails in man-made and natural water bodies in Benue state, Nigeria. Eight sites were sampled for the presence of snails using the sweep net and handpicking method. Snails captured were carefully placed into pre- labelled specimen bottles and transported to Benue State University Zoology Laboratory for identification. Plants commonly known to be suitable for snail attachment were collected and brought to the Botany laboratory for identification. The physiochemical parameters of the water were also documented. Data was processed using Analysis of Variance (ANOVA). A total of 1038 snails belonging to 3 species were identified; Melanoides tuberculata, 468 (45.1%), Lanistes libycus 210 (20.2%), Bulinus species 360 (34.7%). Northbank dam harboured 2 (Bulinus and Melanoides) out of the 3 species recorded, making it the most favourable habitat sampled. Bulinus species was the most abundant in the natural habitats while it was replaced by Melanoides tuberculata in the man-made water bodies. ANOVA revealed a significant difference in relation to snail species encountered, and species abundance in habitats sampled (P< 0.05). The predominant aquatic flora encountered were Ipoemoea aquatic and Nelsonia species. The study revealed that natural and man-made water bodies in Makurdi and Ochobo support the breeding of snail species that have serious epidemiological implications.
Demand Driven MRP – The need to standardise an implementation process.
Authors: Orue A. , Lizarralde A. , Kortabarria A.
Published: July 2020

Since the creation of the demand-driven material requirement planning (DDMRP) model, numerous studies have analysed the methodology’s significant impact on different organisations. Several successful cases and research studies into DDMRP have demonstrated that the methodology is beneficial to organisations because it increases their service level and stock adjustments; however, there is a dearth of literature regarding the steps necessary to implement this model successfully. This document delivers a systematic review of the literature based on the work done by Kitchenham (2004) with the aim of analysing studies that investigate the standardization of the process of implementing the model. Once the lack of research has been demonstrated, a possible line of future research can be outlined to standardise the implementation process of the DDMRP model to achieve its full potential.
Human Development in the European Union and its Determinants
Authors: TUDORACHE Maria-Daniela
Published: July 2020

Human development is one of the most important forms of development, which could enhance the sustainable development process. Through this paper, the evolution of human development index in the European Union was analysed in the period 2010-2017, and the effects exercised by its determinants were estimated. In this context, panel data was used for the period specified above and the Estimated Generalized Least Squares were applied, weighted with the Period SUR option. The results show an inverse relantionship between two variables (early leavers from education and training rate, and employment in agriculture) and the human development index. In addition, human development increases not only when the corruption dimension falls down, but also when life expectancy and gross fixed capital formation increase.

Abstract. In this work, we use Coupled Model Intercomparison
Project Phase 6 (CMIP6) simulations from 10 Earth system models (ESMs) and
general circulation models (GCMs) to study the fast climate responses on
pre-industrial climate, due to present-day aerosols. All models carried out
two sets of simulations: a control experiment with all forcings set to the
year 1850 and a perturbation experiment with all forcings identical to the
control, except for aerosols with precursor emissions set to the year 2014.
In response to the pattern of all aerosols effective radiative forcing
(ERF), the fast temperature responses are characterized by cooling over the
continental areas, especially in the Northern Hemisphere, with the largest
cooling over East Asia and India, sulfate being the dominant aerosol surface
temperature driver for present-day emissions. In the Arctic there is a
warming signal for winter in the ensemble mean of fast temperature
responses, but the model-to-model variability is large, and it is presumably
linked to aerosol-induced circulation changes. The largest fast
precipitation responses are seen in the tropical belt regions, generally
characterized by a reduction over continental regions and presumably a
southward shift of the tropical rain belt. This is a characteristic and
robust feature among most models in this study, associated with weakening of
the monsoon systems around the globe (Asia, Africa and America) in response
to hemispherically asymmetric cooling from a Northern Hemisphere aerosol
perturbation, forcing possibly the Intertropical Convergence Zone (ITCZ) and
tropical precipitation to shift away from the cooled hemisphere despite that
aerosols' effects on temperature and precipitation are only partly realized
in these simulations as the sea surface temperatures are kept fixed. An
interesting feature in aerosol-induced circulation changes is a
characteristic dipole pattern with intensification of the Icelandic Low and
an anticyclonic anomaly over southeastern Europe, inducing warm air
advection towards the northern polar latitudes in winter.
