Published: June 2023

O tema “direito e a política espacial” atualmente tem ganhado mais visibilidade e, por conta disso, tido múltiplos avanços, que acontecem de forma rápida e avantajada, o que acaba abrindo portas para a exploração do assunto por diversas perspectivas e atores. Assim, com o interesse dos Estados na área do direito espacial, e levando em consideração que o espaço não tem um “dono”, resultou em diversos lançamentos de satélites à órbita de forma totalmente desequilibrada. Foi nesse momento que a comunidade científica teve que tomar frente e emitir um alerta explicando os riscos dessa situação, principalmente na questão da sustentabilidade. Tendo em vista os fatos apresentados anteriormente, o presente estudo tem como objetivo analisar o avanço do direito espacial e de suas novas tecnologias averiguando quais benefícios podem trazer para a qualidade de vida da população mundial, além de um diagnóstico de como a governança global espacial pode ser aplicada para a evolução das questões sustentáveis e novas tecnologias. Por fim, indaga sobre a questão da sustentabilidade no cenário espacial, em razão do aumento das atividades espaciais ao longo das últimas décadas, de modo a explicar de que maneira é mais viável manter essas atividades, de forma sustentável, levando em consideração que os resíduos espaciais são extremamente prejudiciais ao meio ambiente. Toda a pesquisa será feita através de fontes de literatura e relatórios internacionais, sendo adotado, portanto, método de pesquisa dedutivo-indutivo, produzido por meio de referencial bibliográfico.

Published: June 2023

Cervical cancer continues to remain a major concern for public health globally. The aim of this study was to determine the positivity level of the Pap test and the prevalence of cervical potentially pre-malignant and malignant lesions in a group of adult women aged 18 years and older in Fier Prefecture in Albania. Material and methods: This cross-sectional study included 1254 women who showed up for a Pap test at the gynecology service at the Fier Regional Hospital during 2013 and 2014. Basic socio-demographic data (age, place of residence, marital status), as well as data related to women’s gynecological history, including information related to menopause status, current pregnancy, menstrual cycle (regular or irregular), data on previous diseases of the genital tract, previous cytological examinations, and previous biopsies, was collected. Adequate cervical smears were interpreted, allowing the calculation of the prevalence of various cervical lesions. Binary logistic regression was used to identify factors associated with a positive Pap test result. Results: The average age of women in our study was 39.8 ± 10.7 years. About two-thirds of women resided in urban area, 99.1% were married at the time of the survey and 17.8% were in menopause. Only 1.8% of women had been subjected to a cytological examination in the past. Among the 1134 adequate cervical smears the level of positive Pap test result was 8.7% and the prevalence of LSIL, HSIL and ASC-US was 4.1%, 1.6% and 3%, respectively. No cases of squamous carcinoma were detected. Age was positively, strongly and significantly associated with a positive Pap result: compared to 21-30 years old women, those aged 31-40, 41-50 and >50 years were significantly 1.98, 6.09 and 14.07 times more likely to have a positive Pap test reading. There was a tendency for the Pap test positivity to be higher among urban woman, probably due to earlier initiation of sexual activity and more sexual partners compared to rural women. Only 2% of women had had cytological examinations in the past. Conclusions: The prevalence of abnormal Pap test among adult women in Fier prefecture was relatively high even though comparable to national and international studies. There is need to increase the awareness of women about cervical cancer and their participation in cervical cancer screening programs.

Published: June 2023

Lignin, the second most abundant biopolymer on the planet, has properties that can be widely explored, moving from waste to products with high added value. Therefore, this work aimed to extract and characterize Klason and Kraft lignins from sawdust and black liquor, considered industrial waste. The raw material used was Eucalyptus grandis chips. To obtain Klason lignin according to TAPPI 222 om-02 (2002), part of the chips were transformed into sawdust. To obtain Kraft lignin, another part of the chips passed through a digester to obtain black liquor, which was subsequently subjected to acid precipitation. The characterization of lignins was performed by granulometry analysis, scanning electron microscopy with elemental chemical analysis (EDS), transmission electron microscopy, medium infrared spectroscopy, thermogravimetric analysis and differential calorimetry. Microscopy analyzes showed irregular structures of various shapes, including spherical structures, most evident and frequent in Kraft lignin. The elementary chemical analysis showed that the lignin washing process was satisfactory, due to the small percentage of sulfur detected in the samples. The results of the granulometry confirmed that the lignins had micrometric dimensions. The medium infrared spectra showed the characteristic peaks of the chemical composition of lignin. The thermal analysis showed three ranges of degradation, attributed to the drying of the samples, degradation of the hemicelluloses and the lignin itself. All results confirmed the obtaining of Klason and Kraft lignins. Therefore, the techniques were satisfactory in transforming waste into lignin with the potential for a variety of commercial applications, mainly in the chemical and pharmaceutical industries.

Authors:   Department of Biomedical Sciences, Faculty of Health Sciences, Mzuzu University, Malawi, Chidzaye Robert W.
Published: June 2023

Medical laboratories provide confirmatory diagnosis and evidence based management of diseases, essential public health information and disease surveillance. A wide variety of research studies suggest that breakdowns in the diagnostic process result in a staggering toll of harm, patient deaths and wastage of valuable medical resources already constrained in the developing world. The objective of this study was to assess barriers to delivery of optimal laboratory diagnostic services in Mzuzu city. This was a descriptive cross-sectional study using quantitative research approach. Three categories of laboratories were selected from the public, faith based and private health systems. Stratified sampling was used to select laboratory practioners while purposive sampling was used to select administrators from each health facility. The data was analysed by the measures of central tendency mean plus measures of variability, range, standard deviation and standard error, using SPSS version 20. The findings of the study were that laboratory practioners identified several barriers to affect quality diagnostic services: 79% of laboratory staff reported short supply of laboratory supplies, work overloads (69%), frequent equipment failure (22%), scarcity of modern equipment (20%) and others. Administrators (67%) reported a limited budget allocation to the public and faith based hospitals. The study also found that there were some barriers that were more frequent than others such as shortage of laboratory supplies (84%), work overloads (70%), lack of refresher training (34%), frequent equipment failure (28%) and others. The study also found that laboratory practitioners employed several countermeasures to overcome technical barriers to diagnostics. 44% reported that they would stop tests when reagents run out of stock, wait for maintenance of equipment and stop tests (38%), higher cadres would delegate work to lower level cadres (31%), improvise on faulty equipment and expired reagents (26%) and many others. No laboratory had adequate quality management systems in place. The recommendations of this study were to strengthen human resources planning for laboratory professionals, establish or strengthen national laboratory regulatory and representative bodies to improve governance and enhance quality, and promote work and competency based in-service training to ensure that staff skills are up to date and competency is demonstrated.

Tulisan ini membahas tentang Analisis Regresi Linear Beganda. Untuk menganalisis pengaruh pendapatan rumah tangga (X1), jumlah anggota keluarga (X2)dan tarif air PDAM (X3) terhadap permintaan volume air pada PDAM Kota Kupang (Y). Setelah itu melakukan Analisa data kuantitatif meliputi, uji validitas, uji asumsi klasik, analisis regresi linear berganda, pengujian hipotesis dengan uji t dan uji F, serta analisis Koefisien Determinan (R2). Data-data yang sudah diuji menghasilkan persamaan regresi linear sebagai berikut: Y = 18474,335 - 770,685X1 + 256,091X2 - 55,197X3. Pengujian hipotesis menggunakan uji t menunjukan bahwa dari variabel X1, X2, dan X3 (Variabel Bebas) yang diteliti tidak terbukti secara signifikan mempengaruhi variabel Y (Variabel Terikat). Kemudian melakukan uji F menunjukan bahwa variabel X1, X2, dan X3 (Variabel Bebas) memang layak untuk menguji variabel Permintaan Volume Air pada PDAM. Angka Adjusted R Square sebesar 0,066 menunjukan bahwa 6,6% variasi Permintaan Volume Air pada PDAM dapat dijelaskan oleh variabel X dalam persamaan regresi. Sedangkan sisanya 93.4% dijelaskan oleh variabel lainnya yang tidak diteliti dalam penelitian ini.

Background and aim: Some recent studies have shown that vitamin D deficiency was a common finding in patients with cardiovascular disease. Because of the high prevalence of cardiovascular disease and vitamin D deficiency in Iranian population, we examined the correlation between vitamin D blood levels and patients with heart failure (HF). Material and Methods: This analytical cross-sectional study was performed using a randomized sampling technique. One hundred forty-five patients who were admitted to hospitals in Tehran from November 2021 to April 2022 participated in this study. Descriptive analysis and inference tests, including chi-square and t-test were used. Logistic regression tests were also used to find the correlations between variables. A P value less than 0.05 was considered for statistical significance. Results: In aggregate, 145 patients with an average age of 59.91 ± 10.75 years were studied. The average amount of vitamin D was 13.3 ± 12.8 ng/ml. This average was 15.0 ±14.2 ng/ml in patients with normal ejection fraction (EF), 14.6 ± 12.9 ng/ml in patients with mild severity EF, 14.1 ± 11.8 ng/ml and 8.7 ± 5.6 ng/ml in moderate and severe severity EF respectively. (p=0.51) Discussion: Although, in our studies, low levels of serum vitamin D and diabetes were not significantly associated with EF, but preventing them is essential in mitigating risk factors in HF.

Listening to Students: The Experiences of Disabled Students of Learning in a Selected University in Zimbabwe
Authors:   Great Zimbabwe University, Manungo Rodgers , Dohwe Tatenda ,   Great Zimbabwe University
Published: June 2023

Disability is one of the most neglected forms of diversity, which usually results in the different forms of discrimination at community level. Nonetheless, more institutions of higher education are making an effort toward creating more inclusive settings for the students and staff. This study examined the lived experiences of the students with disabilities in an institution of higher education in Zimbabwe. Student experiences and disability are the main themes in this study. This study is phenomenological research that was carried out with a questionnaire survey which was conducted among seven participants. This was triangulated by interviews that involved two participants. Overall results showed that physical disability is the most prevalent amongst the students in the institution considered for the study. Moreover, the disabled students faced challenges at home and in their life at university, which affected them psychologically. In addition, while the students were conscious of the existing international and national protocols that promote their welfare, they were not well aware of those embedded within their university policies. Results also reveal that the disabled students suffered socially from stigma and negligence from their able-bodied counterparts and staff. Further, they had limited access to some of the physical structures that lacked ramps and lifts. To promote full participation of the disabled students in academic life, the institution is expected to formulate and implement a binding disability policy that promotes diversity and inclusive education. In addition, infrastructure, especially the old structures need to be refurbished with the disabled in mind.
