Objective

The objective of this study was to provides a descriptive analysis of the clinical outcomes achieved in oocyte vitrification in cases of unavailable sperm on oocyte retrieval day, and to find predictors of oocyte survival.
Methods

This retrospective cohort study used data from a university-affiliated reproductive medicine center. There were 321 cycles carried part or all oocytes vitrification due to unavailability of sperm from March 2009 to October 2017. A descriptive analysis of the clinical outcomes including both fresh embryo transfers and cryopreserved embryos transfers was provided. The ability of an individual parameter to forecast oocyte survival per thawing cycle was assessed by a binary logistic regression analysis. The cumulative probability of live birth (CPLB) was estimated by using the K-M method according to the total number of oocytes consumed in consecutive procedures.
Results

The average survival rate was 83.13% (95% CI 81.81–86.35%). High-quality embryo rate decreased significantly (33.33% vs. 53.75%, P < 0.0001) comparing to fresh control oocytes. The live birth rate per warmed-oocyte was 4.3%. Reasons for lack of sperm availability on oocyte retrieval day and serum cholesterol level were found to be associated with oocytes survival rate in present study. The Kaplan–Meier analysis showed no significantly different CPLB between patients ≤ 35 versus > 35 years.
Conclusions

Oocyte vitrification is proved to be an indispensable and effective alternative when lack of available sperm on oocyte retrieval day. Present study provided evidences that the oocytes from infertile population were more likely suffer to vitrification injury. Clinicians need to take this into account when giving suggestions to patients for similar situations. Further studies will be necessary to clarify the correlation between serum sterol lipids levels and human oocyte survivability after vitrification.
Implementation of Extra Efficient Bandwidth Utilization Dynamic Bandwidth Allocation Algorithm to support Differentiated service classes in XGPON
Authors: Thangappan Theresal , Therese Brintha
Published: May 2021

Dynamic Bandwidth Allocation (DBA) algorithm is necessary for the efficient utilization of bandwidth in XG-PON. Most of the existing DBA algorithms have not utilized the unused bandwidth of a queue with other service classes queue. The Efficient Bandwidth Utilization (EBU) uses a Borrow Refund (BR) method in the update operation to use the unused bandwidth between a traffic class queue of which has some flaws in the BR method. The EBU mechanism causes a reduction in the allocation of bandwidth and increases the delay for the next traffic class. This paper presents an Extra Efficient Bandwidth Utilization (EEBU) algorithm, which overcomes the limitations mentioned above with proper polling and scheduling mechanism. The theoretical and simulation results show that EEBU improvements for T-CONT 2 delay are 1% and 10%, and for T-CONT 3 delay are 8% and 22%, and for T-CONT 4 delay by 6% and 4.5% compared to the EBU and Giga PON access network (GIANT) respectively.

Published: May 2021

Background: Burnout has negative psychological and physical consequences for physicians in training. Mindfulness-based stress reduction (MBSR) has a promising track record for improving well-being. This study aims to demonstrate biophysical and psychological benefit from the incorporation of MBSR into the curriculum of an urban anesthesiology residency program.Methods: This prospective cohort study compared the effect of a voluntary 18-month (January 2018 – June 2019) biweekly MBSR course to an active control (availability of virtual cognitive behavioral therapy (CBT) curriculum and app-based mindfulness tools). Biometric data (e.g., sleep quantity and quality, physical activity and heart rate variability) from wearable devices; hair cortisol levels, and Maslach Burnout Inventory scores were compared between and within cohorts. Results: Data collection was discontinued at the end of the first year of the study due to poor utilization of the in person MBSR and virtual/ app-based trainings. Of 76 eligible anesthesiology trainees, 38 participated (50% of total eligible). Depersonalization scores were significantly lower in the MSBR group. Emotional exhaustion and depersonalization scores were significantly higher for clinical anesthesia (CA) CA-2 (post-graduate year (PGY)-3) than CA-1 (PGY-2) residents. There were no significant differences between cohorts for biophysical outcomes. Conclusions: The implementation of an in-person MBSR curriculum for anesthesiology residents in an urban setting suffered from low utilization. Depersonalization scores were significantly lower in the MBSR compared to the active control group. Perioperative training programs may find more utility in wellness initiatives that are not reliant on inflexibly scheduled courses that require additional time commitment on the part of trainees.

Authors: Alshemmari Hassan
Published: May 2021

A comprehensive study from the surface soil samples of 14 locations from Amghara, Kuwait were assessed for the investigation organochlorine pesticides (OCPs). Due the high degree of contamination in the environment and the health consequences of OCPs, the assessment of these compounds had a significant concern. There is limited informations regarding the distribution pattern of OCPs in the soil samples of Kuwait. The study comprises 12 OCPs including their isomers. Pesticide residue analysis was done with a gas chromatograph for organochlorine pesticides (OCPs) coupled to a triple quadruple mass spectrometer in electron ionization mode. The total concentration of OCPs were in the range of 209.39 pg/g -7449.18 pg/g with an average value of 1313.04 pg/g. DDT had higher concentrations in soil samples (969.52 pg/g) than the other pesticides, according to the findings. The distribution pattern of OCPs in the Amghara soils revealed their origin as both historical and recent application of pesticides. The impact of soil pH on the distribution of DDTs in Amghara soil samples were also investigated. The study further looked at how residual quantities could be used to determine health risks of both children and adults. Children and adults in all the locations were subject to negligible cancer risk, according to the health risk evaluation. OCP's cancer dangers from ingestion, dermal exposure, and inhalation of soil particles indicated that all stations were in the safe zone.

Published: May 2021

NavIC L-band satellite signal that travels from the satellite to the receiver undergoes mainly shadowing and multipath effects. In this research paper, NavIC satellites were observing and analyzing signal efficiency for both the direct signal and multipath signal over the Dehradun area. Two open space data series (Direct signal and Multipath signal) for Dehradun were obtained in this analysis by the satellite receiver. The methodology includes evaluation, testing, and analysis of data in both cases. Based on collected data, a general mathematical model has been developed, describing the signal intensity in the open space context. The both NavIC Mathematical model was validated with the experimental data. The average R 2 and RMSE values developed for the direct signal mathematical model were 0.89 and 1.08% respectively which show a good prediction of NavIC C/N0 value with the developed model. For the multipath mathematical model, four cases have been evaluated. Comparing the graphical view of all four cases for C/No multipath signal concerning raw NavIC C/No multipath signal has been done to select the best mathematical model.

Published: May 2021

One of the most important and widely used renewable energy sources is hydroelectric energy produced via Water Reservoir Impoundment (WRI). WRI can trigger strong earthquakes under favourable geological conditions. Thus, the socio-economic impact of reservoir triggered seismicity is very significant. Although many studies have investigated the relationship between the pore pressure changes due to WRI and the observed seismicity, hydromechanical models that explain the observed processes are rare. Here, we investigate the role of hydromechanical interactions during fault deformation to understand earthquake swarm bursts under pore pressure changes due to WRI. As a natural laboratory, we selected the Song Tranh 2 Reservoir in Vietnam. Because the analysed triggered seismicity has swarm characteristics, our work contributes to the further investigation of the physical mechanisms responsible for earthquake swarms and their relationship to slow slip. We conclude that the small high-frequency seismic swarms accompanying WRI are driven by slow slip along a fault; they occur due to the temperature-controlled frictional fault heterogeneity, and their rate and magnitude depend on the sizes of these heterogeneities. Swarm earthquakes are the effect of slip acceleration on the seismic radiation level. The nucleation fronts expand the nucleation regime and may transition into stronger earthquakes. These results provide insights into the physical mechanisms of seismic processes triggered by WRI, which may have implications for assessing the seismic hazards associated with hydroelectric energy production.
REVIEW OF THE FUNCTIONING AND DEVELOPMENT OF THE DERIVATIVES MARKET
Authors: Zaitsev O. , Olondar A.
Published: May 2021

The article draws attention to a specific market of derivative securities - the derivatives market. At the present stage of development of communication technologies, there is a steady increase in the general trend of direct participation of individuals in financial transactions using electronic platforms. In particular, there is an interest in the participation of Ukrainian citizens in operations on world stock markets. It is emphasized that relatively technically easy access to participation in financial transactions through the use of electronic platforms is currently a potential threat to financial security for the funds of participants in such transactions. This is due to the weak professional training of most domestic financial professionals to assess the capabilities of the derivatives market, as well as to participate in transactions with them. It is emphasized that stock exchange operations on stock markets, purchase and sale of derivatives on electronic platforms, require, along with general, also special knowledge on certain specific areas of economic development and financial relations. From the standpoint of such trends, this review article is proposed. The article provides a brief overview of the functioning of the derivatives market (derivatives) in order to get acquainted with the principles of its operation, as well as with the most common strategies and related terms. The article mentions four main types of derivative contracts: forwards, futures, options and swaps. It is noted that the vast majority of derivative products are valued at five main asset classes: equity, fixed income instrument, commodity, foreign currency and credit event. Mechanisms of trading in derivative securities, which are divided into exchange and over-the-counter, are considered. Historical examples of negative and positive transactions with derivatives are given. The conclusion emphasizes that the economic potential of the stock market of financial derivatives does not appear at the same time as a result of the adoption of legislation. This potential is gradually formed as a set of market opportunities, competitive advantages, means and sources of development of stock exchanges. The formation of the economic potential of the stock market of financial derivatives involves the implementation of a set of coordinated organizational and economic transformations, which are carried out with the active support of regulatory authorities.

The cultural dynamic of water management: Practical demonstration
Authors: Zheng Xiao Yun
Published: May 2021

Water culture has played an important dynamic role in water management historically, and it remains highly valuable for water management and water sustainability today. Water management was influenced by water related value, ethics, knowledge, norms, social behavior, institutions, etc. The role of water culture in water management could be played out from the local to the national scale. As well as using traditional water culture, it is valuable to encourage water culture dynamics in the water management process. Water culture can be used in policy making, capacity building, social awareness establishment, behavior fostering, engineering construction, etc. Simultaneously, it needs to stimulate more new water cultural elements to meet the demands of water management. This chapter aims to discuss the cultural dynamic mechanism in water management, practical demonstrations of water culture in current water management and how to foster new water culture for sustainable water management.
Urban hydro-technologies in Crete, Greece through the centuries
Authors: Angelakis Andreas N.
Published: May 2021

The history of water supply and wastewater engineering in Crete, Greece dates back more than ca. 5,000 years, to the early Bronze Age. One of most advanced achievements in Minoan palaces and other settlements was the architectural and hydraulic functions of water supply and sewerage systems. Minoan hydro-technologies were diffused to Greek mainland, where more advanced sophisticated hydro-technologies were invented, with a peak during the Classical and Hellenistic periods, when they spread over from Greece to India in east and Egypt in the south. The Roman Empire, which replaced Greek rule in most of this area, inherited the hydro-technologies and further developed them, thereby changing their scale of application. Urban water and waste- and storm-water management in Crete were very little improved in both in principle and in scale, during the Byzantine and Venetian periods; however, those constitute the underpinning of modern achievements in water engineering and management practices. The scope of this chapter is to present the most characteristic examples of ancient hydraulic works and related hydro-technologies and their uses through Cretan civilizations.
Agricultural water management customs in Japan: Adaptive changes, recent trends, and future issues
Authors: Takeda Mari
Published: May 2021

This paper focuses on the customs of community-based irrigation management (CBIM) in Japan, which represent Japanese water culture. There are two aspects to the customs of irrigation canal management: (1) the custom of assigning maintenance work responsibility among stakeholders; and (2) allocation of maintenance workload. These customs have changed over time due to socio-economic changes in rural communities and the physical changes in irrigation. In this sense, adaptive change in water culture at the rule-in-use level may contribute to maintaining CBIM. Depopulation and aging in rural society have a severe influence on CBIM and government policy, which promotes public involvement in agricultural water management. In the future, promotion of public participation may influence water culture and create a sustainable collaborative relationship of irrigation management among stakeholders.
Development of water conservancy irrigation and local social reconstruction: A case study in Putian, Fujian Province, China
Authors: Du Longjiang
Published: May 2021

The Putian Plain is essentially the land created from a coastal swamp with the support of a huge hydraulic system, which means that the relationship between man and water has been decisive for the rise and fall of Putian. With a sophisticated water system, the Putian people created artificial plains from the coastal swamp, by a process similar to land reclamation in the Netherlands. The water system is used to control the water level on the plain, drain seawater, introduce freshwater, and develop the land. Under such a man-and-water relationship, focus is given on the relationship between the hydraulic development and social organization in Putian Plain. In the field investigation, it was found that the development of Putian Plain was based on the construction of awater irrigation system, and the management and distribution of water resources was realized through civil organizations, which created a unique folk ritual alliance and traditional cultural etiquette that helped to reconstruct the social organization and interest space in Putian Plain. It also helped to form a stable social organization structure and achieve a balance between cooperation and conflicts. The farmland water systems formed during the history of Putian not only reflect the development of agricultural productivity, but also reflect the reconstruction of social organization in the production process. It is, however, a typical case study of the relationship between water resources management and social organization.

Disasters caused by extreme precipitation under global warming are anticipated to have a strong negative impact on urban construction and social security. In this study, daily grid precipitation datasets of the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) for the period 1961–2018 were extracted to explore the temporal and spatial characteristics of extreme precipitation by using regression analysis, moving average and kriging interpolation. The frequency and intensity indices showed an increasing trend, whereas a decreasing trend was found for the persistence indices, which indicates that GBA tends to slowly become wetter. The mean values of extreme precipitation indices (EPIs) in GBA generally increased from west to east and from north to south. Except for the indices of consecutive wet days and consecutive dry days, other EPIs showed an upward trend in most regions, especially in coastal cities where floods are more likely to occur. Principal component analysis and regression analysis showed that the correlations between the EPIs mostly passed the 0.05 significance test, which suggests that they had a good indicator of extreme precipitation in GBA. This study provides a theoretical basis for extreme precipitation disaster prevention and control within the urban agglomerations of the GBA.

Published: May 2021

In intermittent drinking water distribution systems, large volumes of the water are wasted due to leaks in the distribution networks. Similarly, user service is not always satisfied in the time required to fill the storage, nor with sufficient pressure. Hence the importance of this study. Measuring the variability of pressure in the distribution network and determining the factors that influence the definition of a sufficient minimum hours of service, is a first step to change to a continuous service 24/7, in order to minimize the volumes of lost water and meet demand. In total, 347 pressure sensors were placed in a network to detect changes in pressure and obtain data for 3 years. This study presents a new approach to determine the operating policy of the operating agency that provides the service intermittently. Two objectives are pursued: pressure variability – to minimize leaks – and define the minimum hours of service. The analysis was performed using multivariate statistical techniques, including principal component analysis, correlation matrix and ANOVAs, to explore the association between objectives. The results obtained show that the pressure distribution has a Gaussian behavior and that the hours of service have a Poisson distribution.

Toplumların yarınını oluşturan bugünün çocuklarının her açıdan sağlıklı yetişmeleri, varlıklarının her türlü suistimal ve istismardan korunması noktasında toplumun her kesimi gibi medyaya da önemli görevler düşmektedir. Çocukların hak ihlallerinin önüne geçilmesi, seslerinin duyurulması, haber dilinde temsillerinin sorunsuz yansıtılması gibi pek çok noktada medya, çocukların temsilinde çocuk odaklı habercilik anlayışı çerçevesinde bir anlayışı sürdürmelidir. Çocuk bireylerin haberlerde yer almasına yönelik her ne kadar haber dilinin sorunlarına farklı çalışmalarla değinilmiş olsa da, bu noktada problemli kullanımın zaman zaman devam ettiği görülmektedir. Yeni medyanın habercilik anlamında sağladığı kolaylıklar yanında bir takım sorunları da içerisinde barındırdığı ortadadır. Bu sorunlar hem habercilik anlamında hem de toplumun haberlere erişiminde karşılaştığı etik sorunlar olarak karşımıza çıkmaktadır. Çocuklara yönelik uygulanan taciz, tecavüz, şiddet, cinayet haberlerinin yansıtılmasında, bireylerin konu ile ilgili bilgilendirilmesi ve çocukların güvenli yaşamı açısından konuya yönelik farkındalık oluşturmak adına bu yönde yapılan haberler de oldukça önemlidir. Ancak bu haberlerde kullanılan haber dili toplumun farkındalığını artırmaya yönelik olmalı reyting kaygıları üzerine kurulmamalıdır. Bu makalede, çocukların haberlerde yer alış şekillerinde yaşanan problemli haber dili nitel araştırma yönteminden içerik analizi yöntemiyle eleştirel bakış açısı çerçevesinde değerlendirilmiştir. Bu amaçla; Leyla Aldemir olayını haberleştirmelerinde kullandıkları haber dili; yayınladıkları haberler ve görseller üzerinden Habertürk, Hürriyet, Sözcü ve Yeniçağ gazetelerinin internet haber sitelerinde 16 Haziran 2018- 10 Şubat 2021 tarihleri arasında yayınlanan toplam 206 haberle incelenmiştir. Yapılan değerlendirme ile yeni medyada çocuklara yönelik şiddet, taciz, tecavüz, cinayet haberlerinde etik ihlallerin devam ettiği gözlemlenmiştir. Çalışmanın elde edilen veriler doğrultusunda daha sonra ki çalışmalar için kaynaklık edebileceği düşünülmektedir.

Plastic represent thousands of materials with different physical, mechanical, and chemical properties. As plastic demand and usage increase, it is undeniable that the amount of plastic waste will increase. Plastic has the features of which cannot rot; it does not decompose naturally; it cannot absorb water or cannot rust. So it will eventually cause problems for the environment. This study aims to determine the compressive strength and tensile strength of concrete mixes that use coarse aggregates of plastic waste as a substitute for natural aggregates / broken rocks. There are three variations of samples made with mutations in the type of plastic used, namely PP (Polypropylene) plastic, PET (Polyethylene Terephthalate) plastic, and PP & PET combination plastic. The specimen is cylindrical, with a size of 10 cm x 20 cm. Compressive strength and tensile strength testing is carried out at 28 days according to SNI standards. The results obtained the compressive strength obtained on each variation of standard concrete samples, PP aggregate concrete, PET aggregate concrete, and PP & PET aggregate concrete, respectively, of 21.64 MPa, 10.61 MPa, 8.48 MPa, and 10.18 MPa. Whereas for the splitting tensile strength of standard concrete, PP aggregate concrete, PET aggregate concrete, and PP & PET aggregate concrete respectively were 2.86 MPa, 1.80 MPa, 1.70 MPa, and 1.80 MPa.

Pagah district is one of the urban areas which has several intersections that support community activities. Therefore, the existing public facilities in this area must support community activities. One of them is to ensure the performance of the intersections in the Pagah area is still in good condition. From secondary data obtained from Jember Regency in 2019 Figures, it shows that the vehicle growth rate in Jember Regency has increased over the last 5 years. The results of the analysis with reference to the Indonesian Road Performance Manual show that the existing performance conditions of intersections in the Pagah district indicate that the delay value at the intersections does not meet the requirements. The methods taken in this study to overcome the existing problems are optimizing the intersection cycle time at the Pagah district.

Abstract

A legal reserve is an important tool for allocating the density of land ownership, based on its social and environmental function. That’s why this paper focuses on an analysis of Brazil’s new Forestry Code. It is analyzed if owners and holders of small areas of family-based agriculture can enforce this new law without harming their own survival and their families’. This research is guided by the essential features of the post-positivist theory of law.

Los conceptos de poder y violencia en Hannah Arendt:un análisis desde la comunicación
Authors:   Universidad Autónoma del Caribe, Navarro Díaz Luis Ricardo , Romero-Moreno Marta C. ,   Universidad Autónoma del Caribe
Published: May 2021

El artículo ofrece una reflexión sobre los conceptos de poder y violencia propuestos por Hannah Arendt, analizados desde una perspectiva comunicativa. El poder definido como posibilidad se sustenta a lo largo del documento como aquella dimen-sión de los seres humanos que existe siempre y cuando existan las relaciones sociales. Para ello se sustenta la tesis que define al poder como aquello que se genera en la interacción de los sujetos comunicantes, es decir, entre los sujetos, en el estar juntos los unos con los otros, al ser vistos y oídos entre sí

Background

The lack of accurate and efficient diagnostic devices for extensively drug-resistant tuberculosis (XDR-TB) makes it a severe threat to global public health. A prospective clinical study in an intended-use cohort was designed to evaluate the Akonni Biosystems XDR-TB TruArray and lateral flow cell (XDR-LFC) to address this gap in tuberculosis diagnostics.

Objective

This paper presents the protocol for a study that aims to document the conceptualization and design of this evaluation method for early dissemination while data collection and analysis are ongoing.

Methods

The clinical study was conducted in three phases. The first phase was to observe changes in bacterial load and culture positivity in patient sputa over time and better understand the diversity of prospective clinical samples. The second phase was to prospectively collect clinical samples for sensitivity and specificity testing of the Akonni Biosystems XDR-LFC device. Lastly, the third phase was to explore the anti-TB drug concentrations in serum throughout the drug-resistant tuberculosis treatment.

Results

The methodology described includes the study design, laboratory sample handling, data collection, and the protection elements of human subjects of this clinical study to evaluate a potential new XDR-TB diagnostic device. A total of 664 participants were enrolled across the three phases. The implemented complex systems facilitated a thorough clinical data collection for an objective evaluation of the device. The study is closed to recruitment. The follow-up data collection and analysis are in progress.

Conclusions

This paper outlined a prospective cohort study protocol to evaluate a rapid XDR-TB detection device, which may be informative for other researchers with similar goals.

Indigenous Mothers’ Use of Web- and App-Based Information Sources to Support Healthy Parenting and Infant Health in Canada: Interpretive Description (Preprint)
Authors: Wright Amy Lynn , VanEvery Rachel , Miller Vicky
Published: May 2021

BACKGROUND

Web-based sources of health information are widely used by parents to support healthy parenting and aid in decision making about their infants’ health. Although fraught with challenges such as misinformation, if used appropriately, web-based resources can improve access to health education and promote healthy choices. How Indigenous mothers use web-based information to support their parenting and infants’ health has not yet been investigated; however, web-based modalities may be important methods for mitigating the reduced access to health care and negative health care interactions that many Indigenous people are known to experience.

OBJECTIVE

This study aims to understand the experience of Indigenous mothers who use web-based information to support the health of their infants.

METHODS

This interpretive description qualitative study used semistructured interviews and a discussion group to understand how Indigenous mothers living in Hamilton, Ontario and caring for an infant aged <2 years experienced meeting the health needs of their infants. The data presented reflect their experiences of using web-based sources of health information to support their infants’ health. The Two-Eyed Seeing approach was applied to the study design, which ensured that both western and Indigenous worldviews were considered throughout.

RESULTS

A total of 19 Indigenous mothers participated in this study. The resulting 4 themes included distrusting information, staying anonymous, using visual information to support decision making, and accessing a world of experiences. Although fewer Indigenous mothers used web-based sources of information compared to mothers in the general population in other studies, tailoring web-based modalities to meet the unique needs of Indigenous mothers is an important opportunity for supporting the health and wellness of both mothers and infants.

CONCLUSIONS

Web-based information sources are commonly used among parents, and ever-evolving web-based technologies make this information increasingly available and accessible. Tailoring web-based modalities to meet the unique preferences and needs of Indigenous mothers is an important method for improving their access to reliable and accurate health care information, thereby supporting healthy parenting and promoting infant health.
