Published: September 2023

This paper aims to reveal the relationship between the quality of family life and the skills of coping with stress among the study sample of Talented Female Students in the Intermediate and High schools in Saudi Arabia n=167 according to a several demographic variables. It also aims to identify the level of the quality of family life and the most common skill in dealing with stress among the study sample. The researchers used a descriptive statistical approach to analyze data. In addition, they used the scale of family life quality as well as the scale of skills of coping with stress for talented students. The results of this paper showed that the talented female students have a high degree of both quality of family life and the skills of coping with stress. Moreover, it showed a positive significant relationship between the quality of family life and the skills of coping with stress. Also, there are statistically significant differences between the talented female students in the level of family life quality for the intermediate school students. However, there are no statistically significant differences between the talented female students in terms of dealing with stress in both intermediate and high school. Furthermore, there are statistically significant differences in the quality of family life level among talented students for those who have 4 to 6 members in their family. In contrast, there are no differences among talented students in the skills of coping with stress according to family members.

Authors: Badejo Oluwakemi .A , Oyemolade T.A , Malomo T.A 
Published: September 2023

Background: Spinal haemangioblastomas are rare benign but potentially devastating vascular tumours. They may occur sporadically or as a component of Von Hippel-Lindau (VHL) disease. There is a dearth of information about these tumours among Nigerians. This study aims to evaluate the clinical profile and outcome of surgery as well as the challenges of management of these tumours in a resource-limited country.
Methods: We retrospectively analysed data from the records of patients who had surgery for spinal haemangioblastoma at our center between January 2004 and December 2018.
Results: We operated 2 cases of spinal haemangioblastomas during the study period (1 male, 1 female). The patients were aged 25 and 50 years. Both patients presented with sensorimotor deficits but only one them had sphincteric dysfunction. The duration of symptoms was 2 weeks in one patient and 18 months in the other. The tumour was located in the thoracic region in both of them. One patient had extramedullary tumour while the had an intramedullary spinal tumour. Both patients were paraplegic at the time of surgery, for 3 days in one patient and more than 4 months in the second patient. Gross total tumour resection was achieved in both individual. The patient with short duration of symptoms and extramedullary tumour made a rapid post-operative neurological improvement while the one with long duration of symptoms and intramedullary tumour remained paraplegic until his demise 9 months after surgery.
Conclusion: Spinal haemangioblastomas are rare tumours. Long duration of symptoms and intramedullary tumour location are predictors of unfavorable surgical outcome

Zur Verwendung von Musik in Agnès Vardas Filmen über Jacques Demy
Authors: Drees Stefan 
Published: September 2023

Im filmischen Schaffen der Regisseurin Agnès Varda (1928–2019) spielen dokumentarische Elemente eine zentrale Rolle. So hat Varda im Laufe ihrer Karriere nicht nur eine höchst individuelle Art des essayistischen Dokumentarfilms entwickelt, sondern auch ihre narrativen Filme mit (fiktiven oder realen) dokumentarischen Passagen durchsetzt. Anhand ausgewählter Beispiele befasst sich der Vortrag mit den Grundlagen von Vardas Praxis des Musikgebrauchs. Im Mittelpunkt steht dabei eine Gruppe von Filmen, in denen sich die Regisseurin mit der Arbeit ihres verstorbenen Ehemannes Jacques Demy (1931–1990) befasst: JACQUOT DE NANTES (1991), LES DEMOISELLES ONT EU 25 ANS (1993) und L’UNIVERS DE JACQUES DEMY (1995). Diese drei Filme erweisen sich als besonders aufschlussreich, weil sie nicht nur eigene Filmmusik besitzen, sondern zugleich auch Material aus Demys Musikfilmen (z. B. aus LES PARAPLUIES DE CHERBOURG, 1964; LES DEMOISELLES DE ROCHEFORT, 1967; PEAU D’ÂNE, 1970; UNE CHAMBRE EN VILLE, 1982) verwenden und es – auf sehr unterschiedliche Weise – als dokumentierten Gegenstand filmisch inszenieren.
Documentary elements are a key feature in the films of director Agnès Varda (1928–2019). During her career, Varda not only developed a highly individual type of essayistic documentary film, but also interspersed her narrative films with (fictional or real) documentary passages. Us-ing selected examples, the paper examines Varda’s use of music. The focus is on a group of films in which the director deals with the work of her late husband Jacques Demy (1931–1990): JACQUOT DE NANTES (1991), LES DEMOISELLES ONT EU 25 ANS (1993) and L’UNIVERS DE JACQUES DEMY (1995). These three films prove to be particularly interesting because they not only have their own film music, but at the same time also use musical material from Demy’s films (e. g. from LES PARAPLUIES DE CHERBOURG, 1964; LES DEMOISELLES DE ROCHEFORT, 1967; PEAU D’ÂNE, 1970; UNE CHAMBRE EN VILLE, 1982) and present it – in different ways – as the subject of documentation.

Can a carbon radical act as a hydrogen bond acceptor?
Authors: Rzepa Henry 
Published: September 2023

Having shown that carbon as a carbene centre, C**:** can act as a hydrogen bond acceptor, as seen from a search of crystal structures, I began to wonder if there is any chance that carbon as a radical centre, C• could do so as well. Definitely a subversive thought, since radical centres are supposed to abstract hydrogens rather than to hydrogen bond to them.
Carbon as a hydrogen bond acceptor: can dicarbon (C2) act in this manner?
Authors: Rzepa Henry 
Published: September 2023

In the previous post, I showed that carbon can act as a hydrogen bond acceptor (of a proton) to form strong hydrogen bond complexes. Which brings me to a conceptual connection: can singlet dicarbon form such a hydrogen bond? Dicarbon can be variously represented as above. The first form shows it as a bis-carbene, with an unbonded lone pair of electrons at each end of a carbon double bond.
The Basic and Clinical Science of Wounds in the Austere Environment
Authors: Langworthy Michael J. , Hankins Kreszentia , Storey Travis 
Published: September 2023

Surgery in developing countries is challenging on many levels. U.S. organizations sponsor approximately 200,000 surgeries performed abroad every year (Miclau et al. 2021a). These altruistic surgeons and physicians– despite their good intentions—may not be equipped with the specific surgical and communication skills necessary for a successful surgery in an austere environment. Surgical skill set, nutrition, facilities, and sociology all play a role in successful surgical outcomes. A thorough understanding of the basic science and clinical science of wounds in the austere environment is imperative for physicians and surgeons providing care in developing nations. Basic science research, in regards to nutrition, parasites; skin, dermal, and bone physiology; as well as microbiome interaction with these structures, can help optimize surgical outcome and reduce adverse events such as infection. Clinical science research and the development of algorithms for surgery in the austere environment can also help improve surgical outcomes and mitigate these adverse events.

Published: September 2023

In regard to teaching career, there have been gender disparities in extent using of teaching methods and strategies among teaching staff in schools which ultimately constrain academic performance of students. The use of gender responsive teaching methods became among the strategies that can enhance the performance of students. The study aimed at assessing the extent use of gender responsive teaching methods (GRTM) among teaching staff in secondary schools in Mafia district, in Tanzania. The study was guided by the following research questions, the first research question was, to what extent do teachers use gender responsive teaching methods among teaching staff in secondary schools?, while second research question was, is there any relationship between students academic performance and gender responsive teaching methods used in the classroom?. The study adopted cross sectional research design using a sample of 249 respondents including 184 students and 65 teachers who were selected randomly. Data were collected through survey, interviews and focus group discussions. Qualitative data were analyzed using thematic analysis and quantitative data were analyzed by descriptive statistics analysis and inferential statistics (Chi-Square). The study found that, some of secondary teachers had moderate awareness on the use of GRTM in secondary schools particularly in class use of gender sensitive language with regard to what is taught, how teaching takes places, how and what is learned in the context of male and female students was high (Mean=6.08±1.833) and use of gender sensitive language used in a class was also high (Mean=4.98±1.833).The study also found that, there is significant association between students academic performance and the extent teachers ensuring that, working groups were mixed comprising male and female students was statistically significant at 5% with a chi square value of 14.48 and P= 0.025.Further, the study found that, there is positive significant association between students academic performance and teachers in encouraging both male and female students to present results in a group work had a chi square of 9.434 and P=0.151 It is concluded that, GRTM had significant influence on students’ academic performance in secondary schools in Tanzania. The study recommends that, education policy makers, curriculum planners, teachers, gender practitioners, NGO’s and CBO’s should provide pre-services and in-services teachers training on GRTM in order to increase uses so as to improve students’ teaching methods.

Published: September 2023

To standardize the sieve size for seed grading in dhaincha during Kharif, 2019–20 and 2020–21, an experiment was carried out. The native dhaincha species was processed using slotted perforated metal sieves with CRD design ranging S1 - 1.4 mm (S), S2- 1.6 mm (S), S3- 1.8 mm (S), S4 - 2.0 mm (S), and S5- 2.2 mm (S). The study realized that 2.0 mm and 2.2 mm sieves recorded highest seed quality standards and yielded larger-sized seeds. the results revealed that the seed recovery per cent in the 1.4 mm screen was maximum, whereas, the seed quality, nevertheless was better when seeds were graded using 2.0 mm and 2.2 mm sieves. From the combined average data of the two years, the highest quality seeds were retrieved by grading the seeds using 2.0 mm screen with good seed recovery per cent viz., SR (92.99%), PP (98.46%), PLS (90.37%), TW (26.16 g), SG (81.63 %), TSL (25.2 cm), SDW (14.4 mg), SVI-I (2103) and SVI-II (1174). Hence, the 2.0 mm screen can be used to obtained highest quality seeds with economical seed recovery.
