Flugmechanik und Flugregelung von Luftschiffen

In der vorliegenden Arbeit wird eine geschlossene algebraische Modellierung der Flugmechanik von Luftschiffen entwickelt und im Rahmen analytischer und numerischer Untersuchungen angewendet. Die Resultate geben eine allgemeine Einsicht in die flugmechanischen Eigenschaften von Luftschiffen und werden in den Entwurf einer Flugreglerstruktur umgesetzt. Neben der Darstellung der Gewichts- und Schubkrafte werden die aerostatischen und thermodynamischen Zusammenhange dargestellt. Der Schwerpunkt der Modellierung liegt jedoch bei der halbempirischen Beschreibung der aerodynamischen Krafte: Die Rumpfumstromung wird uber einen Potentialstromungs- und einen Querstromungsansatz, die Leitwerke mit Hilfe der Traglinientheorie und einem Querstromungsansatz modelliert. Das resultierende verteilte Aerodynamikmodell kann lokale Anstromungsbedingungen infolge stationarer und instationarer Windfelder berucksichtigen. Es wird detailliert mit der Losung nach der Theorie schlanker Korper verglichen. In der Modelldiskussion wird auf besondere Eigenschaften der Luftschiffaerodynamik, wie beispielsweise die scheinbare Masse Effekte, eingegangen und die Wirkung des Windes erlautert. Die flugmechanischen Untersuchungen behandeln sowohl Flugleistungsaspekte als auch Fragen der Manovrierbarkeit, Steuerbarkeit und Stabilitat. Die wesentlichen Eigenschaften wie Steigleistung, Kurvenflugeigenschaften und Eigenbewegungsformen werden durch algebraische Beziehungen und einfache Diagramme dargestellt. Ihre Empfindlichkeit gegenuber Variationen der Modellparameter werden auch mit Hilfe numerischer Simulationen untersucht. Abschliesend wird gezeigt, welche Signalruckfuhrungen die Luftschiffdynamik positiv beeinflussen und es wird eine einfache Reglerstruktur zur Regelung der Langs- und Seitenbewegung entwickelt. This thesis presents a closed algebraic model of the flight mechanics of an airship. The model is applied for analytical and numerical studies to give an insight into the flight mechanical properties of airships. Based on this knowledge, a flight control concept is developed. The modeling part discusses the effects of weight and thrust as also of aerostatics and thermodynamics, but the emphasis is on the description of the aerodynamic model. The aerodynamics of the hull are modeled using potential flow and cross flow, whereas the empennage area is modeled by lifting line theory and cross flow. The resulting description is able to consider distributed flow conditions as they can be found in non-uniform steady as also unsteady windfields. Properties of airship aerodynamics are discussed with emphasis on the effect of apparent masses and wind. Flight performance as well as dynamical aspects like controllability and stability are then analysed. If possible, the properties are expressed with algebraic relations or simple diagrams. But also numerical simulation are used, e.g. to study the sensitivity to parameter changes. It is finally shown, how simple feedback structures influence the dynamics of the airship in a positive way. The schematics of a control system for the longitudinal and the lateral motion is presented.
Efficacy and Risk Factors of Pyrrotinib in Second- and Third-Line Treatments for HER2-Positive Advanced Breast Cancer

A study to examine the efficacy and risk factors associated with pyrrotinib in the second- and third-line treatment of advanced breast cancer with Human epidermal growth factor receptor 2- (HER2-) positive cells was conducted. Progression-free survival (PFS) was assessed as the primary endpoint, and the objective response rate (ORR), overall survival (OS), and safety were secondary endpoints. Across all the patients, the ORR was 48.57%, and the disease control rate (DCR) was 94.29%. In the follow-up period, the median PFS was 15 months, and second-line treatment had significantly longer PFS than third-line treatment (P = 0.027). The OS among all the patients was up to 28 months, but the median OS has not yet been reached. Diarrhea (69.57%) was the most important AE, mainly in grades 1 and 2. According to the COX regression analysis, brain metastasis was a risk factor for PFS, while second-line treatment and capecitabine chemotherapy were relevant to a longer PFS correlation among patients. In the second- and third-line treatment, pyrrotinib is still highly effective and safe. Pyrrotinib is a potential ideal salvage treatment plan for patients who failed in first-line treatments.
Use of Honey in the Management of Chemotherapy-Associated Oral Mucositis in Paediatric Patients

Background Oral mucositis (OM) is a critical condition during chemotherapy in both adult and child cancer patients. Paediatric cancer patients have a higher prevalence of OM than adult cancer patients. Honey is a natural product that has been reported to have the best tissue healing properties. The present mini-review focused on the evaluation of the effectiveness of oral care with honey products in the treatment and prophylaxis of chemotherapy-induced OM in child patients. Methods A network of electronic English databases including CINAHL, CENTRAL, EMBASE, MEDLINE and PubMed, were used for primary search from April 2010 to April 2020. We have also considered data collected from ClinicalTrials.gov, Web of Science and Google Scholar. PRISMA software was used to build collective data. Controlled trials were included in this review and were critically appraised by Down and Black. The narrative synthesis was performed. Results A total number of 346 data of children and adolescents with cancer were considered in this short review. All patients were from three randomized controlled trial articles and two were non-randomised controlled trial articles. Based on the evidence so far revealed, honey may show an effect in the treatment and prophylaxis of OM. The analysis of collected data revealed that the probability value P<0.05. The honey enhanced recovery time and severity of OM were significantly compared with those without honey treatment receiving group of pediatric patients. Conclusion Honey not only has been shown to have the capability for healing injured tissues but it is also a more economical treatment, and it has fewer side effects compared to synthetic drugs. Honey or honey products can prevent chemotherapy-induced OM (CIOM) and be the best treatment to grade I, II and III CIOM. However, it is disappointing that studies involving children as patients were few, and limited data available so far.
Evaluating 60 GHz FWA Deployments for Urban and Rural Environments in Belgium

Fixed wireless access (FWA) provides a solution to compete with fiber deployment while offering reduced costs by using the mmWave bands, including the unlicensed 60 GHz one. This paper evaluates the deployment of FWA networks in the 60 GHz band in realistic urban and rural environment in Belgium. We developed a network planning tool that includes novel backhaul based on the IEEE 802.11ay standard with multi-objective capabilities to maximise the user coverage, providing at least 1 Gbps of bit rate while minimising the required network infrastructure. We evaluate diverse serving node locations, called edge nodes (EN), and the impact of environmental factors such as rain and vegetation on the network design. Extensive simulation results show that defining a proper EN’s location is essential to achieve viable user coverage higher than 95%, particularly in urban scenarios where street canyons affect propagation. Rural scenarios require nearly 75 ENs per km2 while urban scenarios require four times (300 ENs per km2) this infrastructure. Finally, vegetation can reduce the coverage by 3% or increment infrastructure up to 7%, while heavy rain can reduce coverage by 5% or increment infrastructure by 15%, depending on the node deployment strategy implemented.

Background: Over the past decade the incidence of Dengue Fever (DF) has increased substantially, and it has emerged as a major public health threat. The objective of this KAP study was to evaluate the knowledge, attitudes, and practices regrading dengue fever. Methods: This Cross-Sectional Study was carried out in Dengue epidemic zones of Rawalpindi. One individual from each household (n = 110) was interviewed. KAP valuation was done by recording scheme. Data were analyzed using MS Excel and SPSS version 21. Chi-square / Fischer exact test and correlation were performed to check the significance of the association. Results: The Participants were from the age bracket of 17 to 26 years; the mean age was 20.2 ± 1.9 years. 53.6% were male and 46.4% were female, and most of them 59.1% were illiterate. A major source of information about infection was reported as news/ radio (73.6%) each, followed by newspaper 68.2%. The mean score obtained by participants was as: knowledge 6.19 ± 1.267; attitude 4.67 ± 1.2 and practice score 3.6 ±1.03. The correlation of these scores revealed a significant positive correlation between knowledge and attitude, and knowledge and practice (p value<0.001). 40.9% of respondents had sufficient knowledge, 54.5% had a good attitude and 64.5% had good practices. Cross tabulation results showed a significant association between knowledge and practices at p-values of 0.02. Conclusion: Overall score for all three categories seems not satisfactory. There is a need to improve the knowledge of the studied area population by involving the residents and health care professionals.

Early meteorological observations in West Africa during the 18th century

This paper aims to present new meteorological data from West Africa during the 18th century. The data sources used are colonial reports, medical treatises on the health conditions in the region, and accounts of exploratory expeditions. The data correspond to five locations in West Africa: Saint‐Louis and Gorée (Senegal), Bulama (Guinea‐Bissau), Freetown (Sierra Leone), and Accra (Ghana). Based on daily and monthly resolutions, approximately 4,400 new meteorological recorded observations were recorded (temperature, precipitation, wind direction, qualitative information on atmospheric conditions). The database obtained is a set of scattered meteorological series with short observation periods and without homogeneous characteristics. However, these data allow us to obtain an overview of the climatic conditions in this area during the study period and information on specific phenomena.

Antibody profile in post-vaccinated & SARS-CoV-2 infected individuals

Background & objectives: During the COVID-19 pandemic it was important to assess the antibody profile in individuals vaccinated with Covaxin (BBV152) and Covishield (ChAdOx1 nCoV-19) with both 28 and 84 days gaps between two doses, those infected with SARS-CoV-2 and post-COVID-19-infected individuals vaccinated with only one dose of either of the vaccines. The present study was aimed to assess these objectives. Methods: Fifty real time reverse transcription–polymerase chain reaction (qRT-PCR)-confirmed COVID-19-infected individuals, along with 90 COVID-19-naïve (BBV152 and ChAdOx1 nCov-19)–vaccinated individuals, were included in the study. Individuals who received a single dose of either vaccine with a confirmed past diagnosis of SARS-CoV-2 infection (n=15) were also included. Blood samples were collected strictly between the 4th and 5th wk after development of symptoms for SARS-CoV-2 infected individuals and after the first/second vaccination dose. Antibody profile assessment was done using whole-virus, spike-receptor binding domain (RBD) and nucleocapsid-specific ELISA kits along with neutralizing antibody kit. Results: There was an overall 97.7 per cent seropositivity rate in vaccinated individuals, and a strong correlation (R2=0.8, P<0.001) between neutralizing and spike-RBD antibodies. Among individuals who received two standard doses of ChAdOx1 nCoV-19 vaccine, the spike antibody levels developed were of higher titre with a longer prime boost interval than in those with shorter intervals (P<0.01). Individuals vaccinated with two doses as well as only one dose post-SARS-CoV-2 infection had high neutralizing and spike-specific antibodies. Interpretation & conclusions: High neutralizing and spike-specific antibodies were developed in individuals vaccinated only with one dose of either vaccine post-SARS-CoV-2 infection. With the main priority being vaccinating majority of the population in our country, single-dose administration to such individuals would be a sensible way to make the most of the limited supplies. Furthermore, neutralizing antibody levels observed in COVID-19-naïve vaccinees imply the need for booster vaccination.
A bifactor model of U.S. parents’ attitudes regarding mediation for the digital age

ABSTRACT Parents use digital-specific strategies to mitigate online risks and augment online benefits of digital technology in their children’s lives. The goal of this study was to develop and validate a measure of parents’ attitudes about mediation of digital technology. An internet-based survey was administered to 460 parents of children and adolescents in the United States. Exploratory bifactor analysis revealed one general factor, reflecting general parenting attitudes, and four digital-specific factors: discursive mediation, restrictive mediation and monitoring, participatory mediation, and mediation by modeling. Confirmatory factor analysis supported a bifactor model of the Digital Parental Mediation Attitudes Scale (DPMAS); the general factor explained shared variance related to parenting style and skills in general, while the mediation factors represented digital-specific attitudes. Construct validity was evidenced in differential associations between mediation factors and parenting efficacy, influence, child age, and parent and child technology use patterns. Impact Summary Prior State of Knowledge: Research exploring the effectiveness of digital parenting strategies (e.g. discursive and restrictive mediation) has not conceptualized or measured these constructs consistently. This limits the extent to which scholars, policy makers, and parents can draw conclusions about the efficacy of digital parental mediation. Novel Contributions: To facilitate a coherent evidence base about digital parenting, the current study developed and validated a quantitative measure of US parents’ attitudes about mediation related to digital and social technologies using structural equation modeling. Practical Implications: The Digital Parenting Mediation Attitude Scale (DPMAS) assess parents’ attitudes across four dimensions (discursive, restrictive/monitoring, participatory, modeling) and can assist in the development and evaluation of interventions to support youth and families in a dynamic and rapidly evolving technological environment.
Serum betatrophin levels and fatty acid profile in gestational diabetes mellitus: Correlation with insulin resistance

Introduction and Aim: Gestational diabetes mellitus (GDM) involves insulin resistance, altered levels of adipocytokines and inflammation. Interaction of various molecules in the pathogenesis of obesity and insulin resistance plays a major role in GDM. Angiopoietin-like protein 8, also named betatrophin is a hormone which is synthesized from liver and adipocytes. This molecule has beta cell-regenerating effect and is proposed to have therapeutic potential in obesity, insulin resistance and diabetes mellitus. The present study aimed to evaluate the role of betatrophin and free fatty acids (FFA) as markers of gestational diabetes mellitus (GDM). Materials and Methods: This study was conducted in Medical College Hospital on pregnant women with the normal body mass index. The study subjects were divided into 2 groups -one with healthy pregnant women and the other GDM and recruited for the study at 24 to 28 weeks of gestation. The levels of betatrophin, insulin and FFA were estimated in the serum and HOMA-IR was calculated. Results: Insulin resistance (IR), serum betatrophin level and plasma omega-6 fatty acid levels were higher, and plasma omega-3 fatty acid levels were lower among GDM subjects in comparison to healthy pregnant women. Fasting plasma glucose, serum betatrophin level and dihomo gamma linolenic acid level showed significant positive correlation with IR while omega 3 fatty acid %, levels of alpha linolenic acid, gamma linolenic acid and lauric acid showed negative correlation with IR in GDM women. Conclusion: Altered fatty acid profile in gestational diabetes mellitus indicated potential application of fatty acids as biomarkers of metabolic derangements which arise due to insulin resistance. The findings have diagnostic, prognostic, and therapeutic implications.

Studies on the Gamma Radiation Responses of High Tc Superconductors

The Future applications of new solid state materials, electronic devices and detectors in radiation environments like Fission and Fusion new generation of Nuclear Reactors, as well as astronomical researches, require a well established understanding about the radiation response of all these items. In addition to foregoing applications the Gamma Radiation (┛R) combined effects of energy dependent displacement per atom (dpa) rates and high penetration strength might be attractive for getting a deeper understanding. In particular for high temperature superconductors (HTS) these are interesting for get a better comprehension about their superconducting mechanisms. Quite controversial results have been reported in ┛R damage studies on HTS, especially on regard to the YBa2Cu3O7-x (YBCO) superconducting behavior. On this way, the papers dedicated to study gamma irradiation effects on the HTS properties are characterized for a lack of coincidence in criteria and results. Some authors have observed an improvement of the superconducting properties with dose increment (Boiko et at., 1988; Leyva et al., 1992), some others report exactly the opposite (Vasek et al., 1989; Elkholy et al., 1996), and other studies have not found any dependence (Bohandy et al., 1987; Cooksey et al., 1994). These contradictions have not been completely explained yet; some authors even attribute these behaviors to a “sample effect” (Polyak et al., 1990). However, Belevtsev et al. (Belevtsev et al., 2000) has determined the relationship between the superconducting order parameter ┦2 and the density of oxygen vacancy rate lower bound, expressed in displacement per atom, in order to achieve significant modification of the superconducting behavior. On this ground, by means of the Oen-Holmes-Cahn atom displacement calculation algorithm (Oen & Holmes, 1959; Cahn, 1959), they calculated the incoming gamma quanta total flux inducing a dpa rate of about 0.02. That makes the YBa2Cu3O7−├ superconducting material mean intervacancies distance close to its superconducting coherence length or order parameter ┦2, in which case the superconducting properties will be modified. Consequently, a systematic behavior of HTS material properties upon ┛R must be expected to be observed, where superconducting intrinsic properties (crystal and electronic structures, critical superconducting temperature), as well extrinsic ones (critical
