Menstrual Disorders Among Nursing Students at Al Neelain University, Khartoum State

Background: Menstrual disorders can severely affect the daily life of young females, particularly the student population, which generates a massive tension that extends to families, but they seldom affect the quality and standard of life. Objectives: The aim of this study was to determine the morbidity nature of menstrual disorders among nursing students and their effect on students’ life activities. Methods: This study was a descriptive cross-sectional institutional-based study conducted at the Al Neelain University, Faculty of Nursing. Of the 200 students recruited, 149 completed the questionnaire with the responding rate of (74.5%). Data were collected using a self-administered structured questionnaire. Results: Of the 149 participants, most were young and in the age range of 18–24 years with a mean age of 21 years. Most students (74%) started their menarche at a normal age range of 12–15 years. A relatively high dysmenorrhea (94.0 %) was observed among the participants. More than half of the respondents (55.0%) had irregular menstruation. Conclusion: The authors concluded that the prevalence and morbidity of dysmenorrhea and menstrual irregularity were high but broadly comparable to those observed in similar developing countries. Therefore, national health policies need to consider the health and educational impact of menstrual disorders on nursing students and develop the plan through a change in students’ lifestyle; moreover, school authorities and teachers need to be aware of the problems to provide psychological and academic support. Keywords: morbidities, dysmenorrhea prevalence, menstrual disorders, nursing students, irregular menstruation
Molecular characterisation of bacteria strains of septic tank sewage samples from related sites in Delta and Edo States of Nigeria using 16S rRNA denaturing gradient gel electrophoresis (DGGE)

The molecular characterization of raw septic tank sewage in the region under study was evaluated using 16S rRNA denaturing gradient gel electrophoresis (DGGE). Raw effluent samples from three septic tanks in the Delta and Edo States region of Nigeria was collected between November 2018 and January 2019 for testing. A composite sample was formed from the three samples collected. The raw sewage sample was sequenced for genomic DNA using Norgen DNA extraction kit to determine the microorganisms present in raw sewage sample. Gene sequence analysis revealed the presence of Methanococcus methanococcus 288171278, Deferribacteres bacterium 291088137, Flavobacteria bacterium 308271278, Bacteroides dorei 671713918, Clostridium difficile 115249003, Kuenenia stuttgartiensis 91203347, Methanosarcina bankeri 827396966, Methanococcus maripaludis 4505076 and Methanobacterium formicicum 693274837, and Desulfitobacterium dichloroeliminans 430782295. The phylogram of the different isolates shows that methane producing bacteria were 7 out of the 13 bacteria isolated; representing 53.8% of the total species occurrence in the sample. Key words: Gene sequence, bacteria, raw sewage, septic tank.
CORRELAÇÃO ENTRE COBERTURA DA ATENÇÃO BÁSICA E TAXA DE IMUNIZAÇÃO: EVIDÊNCIAS PARA AS CAPITAIS DO NORDESTE.

Primary health care and the family health strategy gained strength from the creation of the Unified Health System - SUS and were gradually expanded through the municipalities' adherence. These are policies that aim to ensure greater proximity to the populations involved, welcoming their needs and defining strategies with an epidemiological basis. This article seeks to analyze the existing correlation between primary care coverage and immunization rates in the state capitals of the northeastern region of Brazil. For this, a descriptive, exploratory and documentary study was carried out, using data available in the information systems of the Ministry of Health, DATASUS and the e-Manager AB from which the variables relating to the coverage of basic tension, coverage was collected. of the family health strategy, the rate of immunization and vaccination dropout from the period 2016 to 2019. As a result, it was found that in the cities evaluated there is a low correlation between the coverage of primary care and the rate of immunization. However, in municipalities where primary care was more present, the rate of dropout from the vaccination program was lower. This shows a negative correlation between the two variables and reinforces the importance of the search by the municipalities for full coverage of the program for users, facilitating access to services and, especially with family health strategy teams, for actively seeking people who started vaccination programming in order to comply with the immunization protocol.
From Non-Modular to Modular Concept of Bidirectional Buck/Boost Converter for Microgrid Applications

In this article, the practical comparison of the operational performance of the modular (or multiport) and non-modular bidirectional buck/boost (bi-BB) DC/DC converter is realized. The main contribution of the work is the evaluation of both concepts based on various aspects, considering the qualitative indicators of the systems relevant for microgrids. Here, we discuss efficiency, electrical properties, costs, and component values. At the same time, critical comparisons are provided for converters based on SiC and GaN technology (non-modular high-voltage SiC-based dual-interleaved converter and modular low-voltage GaN-based). The concepts are specific with their operating frequency, whereby for each solution, the switching frequency is different and directly influences relevant components. The efficiency, overall system volume, output voltage ripple, and input current ripple are compared mutually between both concepts with a dependency on power delivery. These factors, together with overall volume and costs, are very important considering modern converters for microgrid systems. The summary of pros and cons is realized for each of the proposed converters, whereby the evaluation criterion is reflected within the electrical properties targeting microgrid application.
Condition-Based Maintenance—An Extensive Literature Review

This paper presents an extensive literature review on the field of condition-based maintenance (CBM). The paper encompasses over 4000 contributions, analysed through bibliometric indicators and meta-analysis techniques. The review adopts Factor Analysis as a dimensionality reduction, concerning the metric of the co-citations of the papers. Four main research areas have been identified, able to delineate the research field synthetically, from theoretical foundations of CBM; (i) towards more specific implementation strategies (ii) and then specifically focusing on operational aspects related to (iii) inspection and replacement and (iv) prognosis. The data-driven bibliometric results have been combined with an interpretative research to extract both core and detailed concepts related to CBM. This combined analysis allows a critical reflection on the field and the extraction of potential future research directions.
Concomitant using of topical carrageenan-kappa and oral vitamin D against 7, 12-dimethylbenz[a]anthracene induced-oral cancer in rats: A synergism or an antagonism effects

Objective: ? -carrageenan is a food stabilizer agent which has an antiproliferative effect, while vitamin D is a prohormone acts on the nuclear receptor and has a cytotoxic against cancer. This study aimed to show the synergistic effect of using topical ? -carrageenan and oral administration of the vitamin D on the 7, 12-dimethylbenz[a] anthracene (DMBA)-induced oral cancer. Material and Methods: fifty four male albino rats were randomly divided into seven groups: Acetone-treated served as control (Group I), vitamin D (5000UI)-treated (Group II), ? -carrageenan (1%)- treated (Group III), DMBA (0.5%)-treated (Group IV), Acetone, ? -carrageenan and DMBA were administered topically on both cheeks and palate, five times weekly for 12 weeks, while the vitamin D was administered orally twice weekly for 12 weeks. Groups V, VI, and VII were animals treated with vitamin D, ? -carrageenan, and both vitamin D and ? -carrageenan for 8 weeks after induction of oral cancer. At the end of the study, blood samples were obtained by cardiac puncture for determination of TNF-? and EGFR. Results: In the groups III and IV, serum EGFR showed significant low levels compared with Group I. In the Group VII, serum EGFR showed a significantly (p=0.014) low level compared with Group IV (614.3±69.7 pg/ml versus 882.4±45.6 pg/ml, respectively). Higher percentages of high levels of TNF-? were observed in the Groups VI and VII, while a lower percentage of EGFR was observed in the Group VI. Conclusion: both ? -carrageenan and vitamin D have antiproliferative effect against DMBA-inducing oral cancer by increasing the levels of TNF-? and suppressing the signaling pathway of EGFR. Concomitant using ? -carrageenan and vitamin D reduces the antiproliferative effect of each other.

Modelling consumer preferences heterogeneity in emerging wine markets: a latent class analysis

ABSTRACT The purpose of this study is to explore the Russian and Chinese emerging markets for imported wines, by assessing Beijing and Moscow consumer demand for different attributes. This study employs the Discrete Choice Experiments technique to evaluate consumer preferences and willingness-to-pay for the selected wine attributes (medals, alcohol level, landscape certification, country of origin, grape variety and price). Results from Latent Class models provide evidence of preference heterogeneity and suggest the existence of two distinct consumer segments in China, and three segments in Russia. In both samples, the wine medals and country of origin are the top selected characteristics. Conspicuous consumption tendencies were found in some segments, with price having a positive impact on utility, probably signalling quality.
Eine Bestandsaufnahme im Angesicht von Streaming Wars und Corona-Krise

Video-on-Demand, auch Streaming genannt, hat in den vergangenen Jahren stark an Beliebtheit gewonnen und ist mittlerweile im Heim-Video-Markt, also dem Kauf oder Verleih von Filmen und Serien in physischer Form oder als Stream, der groste Umsatztreiber. Die Corona-Krise hat diese Entwicklung sogar noch verstarkt. Generell werden zahlreiche Geschaftsmodelle unter dem Uberbegriff Streaming zusammengefasst. Diese konnen in funf Kategorien eingeordnet werden: Einerseits gibt es die werbefinanzierten Angebote (Advertising-supported Video-on-Demand) und andererseits die kostenpflichtigen Angebote. Zu den kostenpflichtigen Modellen zahlt das Abonnement-Modell (Subscription-Video-on-Demand), das Zahlen fur einen Einzelabruf ohne Download (Transactional-Video-on-Demand) und das Downloaden von Inhalten gegen Entgelt (Electronic-Sell-Through). In Deutschland kommen die beitragsfinanzierten Streaming-Angebote offentlich-rechtlicher Anbieter hinzu. Zurzeit wird Streaming insbesondere von jungeren Konsumenten genutzt. Gemessen an den Nutzerzahlen sind die werbefinanzierten Angebote am erfolgreichsten, wahrend die grosten Umsatze mit Abonnements erwirtschaftet werden. Aufbauend auf der Analyse der Geschaftsmodelle und deren Nutzung konnen funf Zukunftstrends des Video-on-Demand identifiziert werden. So wird die Beliebtheit von Streaming insgesamt weiter zunehmen und im Besonderen wird die Verbreitung entsprechender Modelle insbesondere bei alteren Konsumenten steigen. Dabei wird eine Monopolisierung des Streaming-Marktes ausbleiben. Video-on-Demand wird mit der wachsenden Beliebtheit auch das klassische Fernsehen verandern und zum Teil verdrangen beziehungsweise vereinnahmen. Bei der weiteren Entwicklung des Streamings konnte sich jedoch die digitale Infrastruktur als Flaschenhals erweisen und die Verbreitung verlangsamen.
The effects of popularity metrics in news comments on the formation of public opinion: Evidence from an internet portal site

ABSTRACT The influence of online comment sections on the news has increased based on the development of collective online behaviors in the digitalized news media era. In this study, we focus on the effect of comment order (e.g., sorting comments by the number of likes or by the time of posting) on the formation of public opinion. We explore whether reading comments sorted by number of likes (a) induces more comments from users, (b) increases the expression of user opinions in response to others’ comments through the action of liking or disliking comments and (c) consolidates user opinion. For the empirical verification of the effects of popularity metrics, we chose a common topic (increasing minimum wage), collected actual data (reviewing 3,251 articles and the numbers of associated comments, likes, and dislikes), and compared news categories based on the existence of popularity metrics. Semantic network analysis was conducted with UCINET and python for K-means clustering, and cosine similarity. Our results show how the comment order in the internet news environment affects the commenting behavior of news consumers.

Novel cichlid-dominated fish assemblages in tropical urban reservoirs

Recent biodiversity surveys in the lentic habitats of Singapore revealed that non-native cichlids (at least 14 species from different origins) were the most abundant species in the reservoirs of Singapore. To understand the diversity and distribution patterns in six reservoirs (two inland and four coastal), we investigated the species richness and abundances of these cichlids. We also investigated foodwebs to characterise the trophic relationships of cichlids relative to the aquatic community using stable isotope and gut content analyses in each reservoir. Based on various sampling methods (electrofishing, netting and trapping), a total of 5,675 individual cichlids representing 14 species and two hybrids were caught. The three most abundant species (contributing to 66.8% of all cichlids) included the green chromide, Etroplus suratensis, the eartheater cichlid, Geophagus altifrons, and the Orinoco peacock bass, Cichla orinocensis. Based on a canonical correspondence analysis, we found that the distribution and abundances of cichlids appeared to be related to abiotic parameters such as salinity and dissolved oxygen, and that species richness and abundances of cichlids differed between coastal and inland reservoirs. We also found that the trophic positions of different cichlid species varied within and across the reservoirs surveyed, where sympatry between highly specialised as well as generalist cichlid species was commonly observed. This was reflected in both the gut contents as well as the empirical foodwebs generated. While we are unable to determine source and timing of the introductions of these cichlids, we are at least confident that many of the cichlids have already established in these six reservoirs. We postulate that the establishment success and the co-existence of this nonnative group has come about through their ability to adapt to the conditions within each reservoir, and this is related to the life history strategies, feeding and behavioural patterns that these different cichlid species display.

Influence of Rainfall on Canopy Interception in Mixed Broad-Leaved—Korean Pine Forest in Xiaoxing’an Mountains, Northeastern China

The mixed forest of broad-leaved and Korean pine is the dominant type in the Xiaoxing’an and Changbai Mountains of China. However, few studies have been done on its canopy interception of rainfall. In this study, rainfall amount, rainfall intensity, and canopy interception were monitored during the growing seasons in 2010 and 2011. The results showed that cumulative canopy interception of rainfall was 22.0% and 21.9% in 2010 and 2011, respectively. However, the canopy interception of rainfall varied with rainfall events from 6.6% to 82.7% in 2010, and from 8.7% to 80.2% in 2011. The relationship between rainfall amount and the ratio of canopy interception to rainfall amount could be described by a power function (P < 0.01), i.e., the canopy interception decreased with the increasing rainfall amount and intensity. These results indicate that the rainfall amount and intensity were important factors for estimating the canopy interception of the studied forest type.
An institutional review: dosimetry comparison between simultaneous integrated boost IMRT and VMAT for prostate cancer

Abstract Purpose: A comparative study was performed about the plan parameters and quality indices between volumetric arc therapy (VMAT) and intensity-modulated radiotherapy (IMRT) for the treatment of high-risk prostate cancer patients. The aim of this retrospective study was to compare the two methods of external beam radiotherapy IMRT and VMAT in terms of plan quality and efficacy. Material and method: Fifteen high-risk prostate patients were planned for radiotherapy using 6 MV photon. Three dose levels were contoured having Planning Tumour Volume 1 (PTV1 = 48 Gy), Planning Tumour Volume 2 (PTV2 = 57.6 Gy) and Planning Tumour Volume 3 (PTV3 = 60 Gy). Setup margins were given using the CHIP trial method. The prescribed PTV3 dose was 60 Gy in 20 fractions which is biologically equivalent to 74 Gy in 37 fractions using α/β = 3. In case of IMRT, seven fixed beam angles 30, 60, 105, 180, 255, 300 and 330 were used and the dose was optimised using the sliding window method. In case of rapid arc technique, one or two full arcs were used for dose optimisation while keeping all the dose constraints and other planning parameters same used in IMRT. The plan evaluation parameters and Organ at risks (OARs) doses were calculated using a dose volume histogram (DVH). Results: The average D2, D5, D95 and PTVmean for PTV3 were 61.22, 61.13, 58.12, 60.00 Gy and 62.41 62.24 59.53 61.12 Gy for IMRT and VMAT, respectively. The averages V60 for bladder and V30 for rectum were 22.81, 25 and 67, 65% for IMRT and VMAT, respectively. The average homogeneity index (HI), conformity index (CI) and gradient index (GI) were 1.04, 1.4833, 14.79 and 1.04, 1.704, 7.89 for IMRT and VMAT, respectively. Conclusion: VMAT takes less dose-delivery time and lesser number of monitoring units than IMRT, thus it compensates the intrafractional movements during dose delivery. The Dose GI in VMAT was much better than IMRT. This indicates sharper dose fall off near the normal tissue. No other major differences were observed in terms of plan evaluation parameters between IMRT and VMAT techniques. So, we conclude that VMAT technique is more efficient than IMRT in terms of plan quality and dose delivery.
Economic benefits of tourism: Cultural identity and tourism destinations in the Czech Republic

Our paper focuses on the economic benefit of tourism by evaluating the compliance between the destination identity and the identity of residents on the example of a selected tourist area. One can see that the identity of the destination is reflected in the product offer and can be found in media messages. The identity of residents was ascertained by a survey. Our research is divided into three main parts. The first part of the research included an analysis of the destination offer within the website and Facebook page. The second part of the research is focused on the analysis of the tourism destination in the media. These two methods are used to analyse the identity of the destination. A group interview was chosen to analyse the identity of residents. The third research was carried out using the focus group method. Our methodical procedure is tested on a case study of a selected destination Toulava (a Czech tourist area located on the border of South and Central Bohemia), however it is designed to be universally usable within tourism destinations. Our results confirmed that the model-defined path for memory destination selection by destination management and its use in the business offer to create product cores works. The high degree of product authenticity has been confirmed. The applied research methodology enabled to obtain relevant outputs. It is not common in general practice that the identity of the destination is examined together with the identity of its residents. The three methods used in this article are less demanding in terms of capacity and cost than the quota sample research. Research can thus be carried out in destinations repeatedly and follow time series.
Assessing occupational risks in pipeline construction using FMEA-based AHP-MOORA integrated approach under Pythagorean fuzzy environment

Abstract The aim of natural gas pipeline projects is generally to make it possible to transfer the natural gas produced from one place to another. There are various safety risks for these broad construction systems. Therefore, to reduce the negative effects of emerged risks, a new risk assessment approach for occupational health and safety (OHS) is needed. In this paper, FMEA-based AHP-MOORA integrated approach under Pythagorean fuzzy sets is proposed for assessing occupational risks in a natural gas pipeline construction project. A case study for concrete coating process of natural gas pipeline project is employed to show the feasibility and effectiveness of the proposed integrated approach. A comparative study, correlation analysis, and sensitivity analysis are also presented to approve the novel risk assessment approach. In conclusion, the integrated approach gives more reasonable results for evaluating the occupational risks in project of pipeline construction using the advantage of Pythagorean fuzzy sets that reflects uncertainty in more suitable way.
