Introduction: Adamawa and Bauchi are cholera endemic states in the north-east region of Nigeria, each with local government areas classified as cholera hotspots. Ineffective implementation of multi-sectoral cholera interventions in both states could make obtaining the global target for cholera control in Nigeria out of reach. A major contributing factor to this challenge is fragility of the region due to persistent Boko Haram insurgency activities, often characterised by the destruction of health infrastruture and displacement of communities to areas with suboptimal living conditions. Given the complexity of disease control in such a fragile setting, this study aims to systematically examine the barriers and/or facilitators influencing the implementation of existing cholera interventions in these states. Methods: The study will use a systems dynamic approach. First, we will conduct a health facility survey to determine the current health system capacity to support multi-sectoral cholera interventions, and conduct key informant interviews with purposely selected state and national cholera stakeholders to identify the context-specific facilitators and barriers to the implementation of cholera interventions in these states. We will then conduct nine group model building workshops (four in both the Adamawa and Bauchi states and one in Abuja) among cholera stakeholders similar to those recruited for the interviews. Conclusion: By engaging diverse and relevant cholera stakeholders, including community members, this study has the potential to provide a rich understanding of context-specific factors influencing the implementation of multi-sectoral cholera interventions in a fragile region of Nigeria, with a view to achieve sustainable progress towards cholera control in the country. Moreover, this study could have an impact on the control of other water-borne diarrheagenic diseases in the country.

Published: February 2021

Background
The systematic review of economic evaluations plays a critical role in making well-informed decisions about competing healthcare interventions. The quality of these systematic reviews varies due to the lack of internationally recognized methodological evaluation standards.

Methods
Nine English and Chinese databases including the Cochrane Library, PubMed, EMbase (Ovid), NHS economic evaluation database (NHSEED) (Ovid), Health Technology Assessment (HTA) database, Chinese National Knowledge Infrastructure (CNKI), WangFang, VIP Chinese Science & Technology Periodicals (VIP) and Chinese Biomedical Literature Database (CBM) were searched. Two reviewers independently screened studies and extracted data. The methodological quality of the literature was measured with modified AMSTAR. Data were narrative synthesized.

Results
165 systematic reviews were included. The overall methodological quality of the literature was moderate according to the AMSTAR scale. In these articles, thirteen quality assessment tools and 32 author self-defined criteria were used. The three most widely used tools were the Drummond checklist (19.4%), the BMJ checklist (15.8%), the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement (12.7%). Others included the Quality of Health Economic Studies (QHES), the Consensus on Health Economic Criteria (CHEC), the checklist of Center for Reviews and Dissemination (CRD), the Philips checklist, the World Health Organization (WHO) checklist, the checklist of Critical Appraisal Skills Program (CASP), the Pediatric Quality Appraisal Questionnaire (PQAQ), the Joanna Briggs Institute (JBI) checklist, Spanish and Chinese guidelines. The quantitative scales used in these literature were the QHES and PQAQ.

Conclusions
Evidence showed that pharmacoeconomic systematic reviews’ methodology remained to be improved, and the quality assessment criteria were gradually unified. Multiple scales can be used in combination to evaluate the quality of economic research in different settings and types.

Numerical modal analysis of a 850 KW wind turbine steel tower
Authors: Ferroudji Fateh 
Published: February 2021

AbstractThe study deals with the numerical analysis aspects that are necessary for identifying of modal parameters of the tower structure as the most important part of the horizontal axis wind turbine, which are basic for the dynamic response analysis. In the present study, the modal behavior of an actual 55-m-high steel tower of 850 KW wind turbine (GAMESA G52/850 model) is investigated by using three-dimensional (3D) Finite Element (FE) method. The model was used to identify natural frequencies, their corresponding mode shapes and mass participation ratios, and the suggestions to avoid resonance for tower structure under the action wind. The results indicate that there is a very good agreement with the fundamental vibration theory of Euler-Bernoulli beam with lamped masse in bending vibration modes. When the rotor of the wind turbine runs at the speed of less than or equal to 25.9 rpm it will not have resonant problems (stiff–stiff tower design). Furthermore, in case the rotor runs at the speed of between 25.9 and 30.8 rpm, the adequate controller is necessary in order to avoid the corresponding resonant susceptible area of the tower structure (soft–stiff tower design).
Assessing ICD-11 gaming disorder in adolescent gamers by parental ratings: Development and validation of the Gaming Disorder Scale for Parents (GADIS-P)

Published: February 2021

AbstractBackground and aimsThe addiction to digital games is associated with substantial impairments in daily functioning and adolescents are particularly at risk. Screening instruments for the new ICD-11 diagnosis Gaming Disorder (GD) are rare and only include self-ratings thus far. Since adolescents' insight might be limited due to young age or symptom denial, external ratings are essential. We therefore aimed to develop and validate the Gaming Disorder Scale for Parents (GADIS-P) in a representative sample of parents and young gamers.MethodsGADIS-P was developed as an adaptation of a recently published self-rating scale. It was validated in 800 parents and their frequently gaming children between 10 and 17 years with standardized questionnaires in an online survey. Item structure was investigated by confirmatory factorial analysis. Gaming time, pathological gaming according to DSM-5, emotional dysregulation, and academic performance were used to derive criterion validity. Accordance with self-ratings was determined. ROC-Analyses were computed to determine cut-off values.ResultsA presumed two-factorial structure of GADIS-P could be confirmed describing cognitive-behavioral symptoms and negative consequences. The instrument showed good to excellent internal consistency (Cronbach's α = 0.89–0.92, McDonald's ω = 0.92–0.95) and criterion validity with moderate to strong correlations regarding gaming behavior (r/ϱ = 0.35–0.76), excellent discriminatory power, and moderate accordance with the adolescents' self-ratings (kappa = 0.47–0.58).Discussion and conclusionsAs the first successfully validated tool for the assessment of ICD-11 GD in adolescents by parental judgment, GADIS-P can make an important contribution to reliable GD screening in clinical and research settings.
Messages, Texts, and Rhetorical Detachment in Contemporary Mahri Poetry
Authors: Liebhaber Samuel 
Published: February 2021

Despite its geographical and linguistic proximity to the Arabic language, the Mahri (or Mehri) language (ISO 639-3: gdq) of Eastern Yemen and Western Oman has remained a non-written language into the present era. While older generations of Mahri speakers never considered the prospect of a written idiom for their language, recent years have witnessed efforts to compose and circulate texts in the Mahri language. These circumstances have yielded a poetic praxis that traverses the domains of orality and literacy; they also enable us to identify lexical and syntactic characteristics that betoken where in the shifting terrain of oral and literary composition a poetic work occurs. I will examine the appearance of one such lexical and structural motif – the dispatched messenger – in a recently composed collection of Mahri language poetry, The Dīwān of Ḥājj Dākōn (2011). Embarking from the notion of textual autonomy developed by Chafe, Olson, and Tannen, I argue that the sudden appearance of the messenger motif in Ḥājj Dākōn’s poetic collection is a by-product of his adoption of a written practice. In this way, we can establish that a stance of rhetorical detachment is a hallmark feature of an emergent written practice, even at its earliest stages.
Stability of Tracking the Delay of Phase-shift Keyed Signals with Spectrum Expanding in Synchronization Systems of Radio Engineering Systems
Authors: Maltsev Georgy , Evteev Andrey 
Published: February 2021

The issues of ensuring the stability of delay tracking in synchronization systems of radio engineering systems when receiving phase-shift keyed signals with spectrum expansion based on pseudorandom sequences are considered. When working with moving objects, the delay of the received signal continuously changes, synchronization errors occur, and the quality of signal reception largely depends on the stability of the tracking scheme for the delay, characterized by the probability of tracking failure. Delay tracking is usually considered as the main task of the synchronization system of the considered radio systems with phase-manipulated signals with spectrum expansion based on pseudo-random sequences.
The effect of synchronization errors when tracking the delay of a received phase-shift keyed signal with a spectrum extension based on pseudorandom sequences on the probability of tracking failure is studied. The calculation method is used to obtain families of dependences of the probability of tracking failure on the values of random and systematic components of the delay tracking error, normalized to the capture band of the time discriminator of the delay tracking scheme for various combinations of these parameters. The areas of weak and strong influence of the value of tracking errors over the delay of the received signal on the probability of tracking failure are determined. The nature of impact of random and systematic components of tracking error on the probability of failure of tracking was analyzed and it was found that in the General case is the ambiguity of normalized mean square of tracking error as the optimization criterion while minimizing the likelihood of tracking loss.
Calculations performed for a wide range of changes in the normalized delay tracking errors show that to ensure a given quality of signal reception in a radio system with phase-shift keyed signals with spectrum expansion based on pseudorandom sequences, a joint choice of parameters of the delay tracking system that determine the value of random and systematic components of the tracking error is necessary. The results obtained can be used to analyze the characteristics of synchronization systems that monitor the parameters of received signals with a spectrum extension, and to justify the technical solutions of the synchronization system that provide the required quality of signal reception in information and measurement of radio-electronic systems.
Основная семья: предыстория и перспективы
Authors: Елисеева Ирина Ильинична 
Published: February 2021

Рассматривается траектория изменений в составе и величине российской семьи в советский период: переход от преобладания сложной семьи к преобладанию простой семьи, от многодетности к малодетности. Акцентируется воздействие государства на российскую семью через законодательство. Выделяется переход от политики расшатывания семейного уклада в 1918-1920 гг. к формированию имиджа семьи как «основной ячейки общества», вступления в брак как государственного деяния. Подчеркивается воздействие законодательства на репродуктивное поведение, прежде всего незамужних женщин, оказавшихся в ловушке традиционной морали. Отмечается существенное влияние половых диспропорций на брачность после Великой отечественной войны. Развитие российской семьи связывается с жилищными условиями и формированием рынка жилья. Среди нуклеарных семей выделяется семья «родители-дети», которая интерпретируется как основная семья с позиций демографического и социального воспроизводства, непосредственности контактов двух поколений. Подчеркивается равноправность признаков основной семьи: наличие гетерогенной брачной пары и несовершеннолетних детей. По данным Комплексного обследования уровня жизни населения 2018 г. показано, что брачные пары без детей имеют большую долю в выборочной семейной структуре, нежели брачные пары с детьми. Так что семьи, трактуемые как основные с позиций репродуктивного потенциала, оказываются неосновными по своей представительности.
Возрастает разнообразие семей, основные семьи трансформируются, приобретая новые характеристики, не свойственные традиционным признакам семьи; трансформация затрагивает также характер супружеских и внутрисемейных отношений. Отмечаются узкие места отечественной статистики, затрудняющие анализ брачно-семейных отношений. Делается вывод об амбивалентности современного российского общества, нелинейности процесса модернизации семьи, включающего возвратные тенденции.

Published: February 2021

Abstract
Growth and developmental parameters of the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), were evaluated on 41 new zoysiagrass taxa (Zoysia spp. Willd.), which belong to an increasingly popular group of warm-season turfgrasses, in comparison with 5 commercially available zoysiagrass taxa and 1 known susceptible Paspalum L. taxon. Results from two no-choice growth chamber trials indicated that the new Zoysia japonica Steud. taxa were unfavorable for the development of fall armyworm larvae in general compared with the susceptible Paspalum taxon. This was evidenced by significantly lower larval and pupal weights and survival and longer time to pupation and adult emergence, pointing to antibiosis in these zoysiagrass taxa. The new Zoysia matrella (L.) Merr., Zoysia macrostachya Franch. & Sav., and Zoysia sinica Hance taxa seemed more favorable than Z. japonica taxa, as evidenced by numerically higher larval and pupal weights and survival and shorter duration to pupation and adult emergence. Taxa that consistently showed low larval survival were identified for further testing.

Subject. Dental examination and identification of the features of the dental status of children with congenital cleft lip and palate, born and living in the region with industrial ecotoxicants.
Objectives. To study the dental morbidity in children with congenital cleft lip and palate living in a region with industrial ecotoxicants, compare the data with a group of children with congenital cleft lip and palate from an ecologically safe region.
Methods. The article presents the results of a dental examination of 195 children with congenital cleft lip and palate, including 108 children aged 3 years, 87 children aged 6 years. Children were divided into two groups depending on the place of birth and residence: 113 children were born and lived in regions with a developed petrochemical industry, 82 children from relatively ecologically safe regions.
In the examined children, the prevalence and intensity of dental caries, malformations of hard dental tissues, periodontal diseases, dentoalveolar anomalies, and the hygienic state of the oral cavity were assessed. To determine the intensity of dental caries in children of 3 years old, the index "KPU" was used, in children of 6 years old - the index "KPU+kp". The hygienic state of the oral cavity was assessed by the Fedorov-Volodkina index (1968), the periodontal condition in children of 6 years old was assessed by the KPI index (Leus P.A., 1988).
Results. Our data indicate that children from regions with the petrochemical industry have higher rates of dental caries intensity in the age groups of 3 and 6 years, there is a decrease in the resistance of the tooth enamel, and periodontal diseases are more common.
Conclusions. The results of the study made it possible to obtain clinical and dental data characterizing the negative impact of industrial petrochemical ecotoxicants on the condition of the dentition in children with congenital cleft lip and palate, which is the rationale for the development of methods for optimizing and increasing the effectiveness of therapeutic and prophylactic measures in this group of patients.

Summary. The composition of supragingival and subgingival dental plaque, gingival and oral fluid, dentogingival or periodontal pocket, are a valuable diagnostic medium for non-invasive diagnosis of inflammatory periodontal diseases, since they contain a wide variety of microorganisms, many of which are markers.
Purpose — non-invasive assessment of markers of periodontal diseases based on the study of the microbial composition of various biotopes of the oral cavity by PCR.
Мaterials and methods. Non-invasive diagnosis risk factors, in particular, the presence of periodontal pathogenic microflora, provided for the study of various biotopes of the oral cavity — plaque, oral and gingival fluids, the composition of the dental pocket by applying a high-quality PCR diagnostic method using commercial DNA-express kits (LLC NPF «Litech», Russia).
Results. A comparative study of markers of the development of periodontal diseases using a qualitative version of the PCR test system in samples of subgingival plaque and dental pocket contents of individuals with initial stage I periodontitis showed 3.1 times greater prevalence of the representative of the yellow complex — Aggregatibacter actinomycetemcomitans, 1.4 times more often than the representative of the red complex P. gingivalis. In the studied material of supragingival plaque, gingival and oral fluid of individuals with gingivitis induced by dental biofilm, the representative of the yellow complex Aggregatibacter actinomycetemcomitans prevails 2.6 times more often than representatives of the red complex — P. gingivalis and Tannerella forsythia, 1.4 times the orange complexFusobacterium nucleatum. In samples of supragingival plaque in individuals with clinically healthy gums with loss of periodontal tissue, representatives of the microflora that form orange, red and yellow complexes most often predominate.
Conclusion. The study of supragingival and subgingival plaque, gingival and oral fluid, and the dentogingival pocket using a PCR test system allows timely detection of markers of the development of inflammatory diseases, regardless of clinical condition of periodontal disease.
