“Su” dünya üzerindeki tüm canlı varlıklar için yaşamın birincil gereksinimidir. Gezegenimizin dörtte üçü sularla kaplı olsa dahi insanların kullanabileceği tatlı su miktarı ise toplam su miktarının sadece %0,0002’si kadardır. Küresel ısınma ve iklim değişikliği sebebiyle yağış rejimleri değişmekte, dünyanın kimi bölgeleri kuraklık kimi bölgeleri ise taşkın ve sellerle mücadele etmektedir. Nüfus artışı, kentleşme ve beşeri faaliyetler sahip olduğumuz kullanılabilir tatlı su kaynakları üzerindeki talep baskısını artırırken, mevcut su kaynakları ise kirletici unsurlar sebebiyle kullanılamaz hale gelmektedir. Su krizleri her geçen gün insanlığı ve diğer çevresel bileşenleri daha fazla tehdit eder hale gelmektedir. Bilim ve teknolojide ilerleyen insanoğlu bir zamanlar kurduğu her yerleşime su götürebilir becerideyken artık günümüz dünyasında götürülebilecek bir su kaynağının kalıp kalmadığı tartışılmaya başlanmıştır. Bu tartışmalar neticesinde ortaya çıkan yegane çözüm ise suyun kendi havzasında yönetilmesi ve yerleşimlerin mevcut su kaynaklarının sürdürülebilirlikleri kapsamında şekillenmesi yönündedir. Bilimsel araştırmalar arazi kullanımının su kaynakları ve su tüketimi üzerindeki etkilerini gösterirken kent planlama süreçlerinde su odaklı çalışmalar önem kazanmaya başlamıştır. Bu çalışmada dünyada ve ülkemizde önemli bir sorun haline gelmeye başlayan su krizi ve kuraklık sürecine karşın kent planlama çalışmalarıyla alınabilecek önlemler sıralanmıştır. Kenti oluşturan konut, sanayi, ulaşım ağları, yeşil alanlar gibi kentsel fonksiyonların tasarımında dikkat edilmesi gereken hususlar sıralanırken, üst ölçeklerden alt ölçeklere doğru su kaynaklarına duyarlı planlama süreçleri hakkında öneriler getirilmiştir. Çalışma kapsamında su duyarlı planlama çalışmalarına yönelik bilimsel araştırmalar temel alınmış, planlama ölçeğinde ise ülke ve bölge ölçeğinden mahalle ölçeğine kadar uzanan su duyarlı bir planlama süreci tariflenmiştir.

DOSAGE OF PHYSICAL ACTIVITY USING DETERMINATION OF VENTILATORY ANAEROBIC THRESHOLD BY CARDIOPULMONARY EXERCISE TEST
Authors: Stojmenović Tamara , Stojmenović Dragutin , Purković Miloš 
Published: October 2023

Dosing physical activity is a very important segment in the exercise domain of every person, whether they are a child, an recreational person or a professional athlete.
The aim of this paper is to present the most optimal and direct method for assessing the functional status of an individual and to explain the way in which physical activity can be dosed most effectively using a Cardiopulmonary exercise test (CPET).
In this work, the descriptive method of conducting the CPET test was used as a standard for determining the beginning of physical activity, but also for determining training thresholds.
Adequate physical activity should be optimally dosed, neither too much nor too little, but sufficient to cause physical adaptation of the organism to effort.
In sport and physical activity, the heart rate parameter and the determination of the degree of fatigue in relation to the maximum heart rate of the person exercising are most often used to measure effort.

Published: October 2023

Objective: Give a background why this model is worthwhile by briefly highlighting the current health system and how this study may help to improve this system. This study aims to assess the impact of the MIRACLE model onquality enhancement and patient safety within healthcare settings.
Study Design: Employing a cross-sectional design, this research centers on four key variables and 19 corresponding indicators. Data were collected using a questionnaire distributed via Google Forms, targeting heads of work units at M. Djamil Central General Hospital in Padang, Indonesia.
Method: The analysis utilizes the Partial Least Squares Structural Equation Modeling (PLS-SEM) technique to evaluate variable relationships. The variables studied are Communitarian, Apprenticing Affinity, Managing, and Quality and Patient Safety, with indicators integrated into the questionnaire.
Results: Communitarian and Apprenticing Affinity emerged as influential factors directly impacting quality of health servicesand patient safety, moderated by Managing variable. Research findings reveal a significant positive impact of the Apprenticing Affinity variable on Managing (p-value = 0.013), underlining its significance in hospital management. Moreover, Apprenticing Affinity significantly affects quality and patient safety (p-value = 0.00), highlighting its pivotal role in healthcare enhancement. Similarly, the Communitarian variable significantly influences Managing (p-value = 0.11), notably impacting quality and patient safety (p-value = 0.00). However, Managing alone does not significantly impact quality and patient safety (p-value = 0.15). Indirectly, the research unveils that the Managing-moderated Apprenticing Affinity variable lacks significant influence on quality and patient safety (p-value = 0.268). Similarly, Managing-moderated Communitarian influence does not substantially impact quality and patient safety (p-value = 0.411).
Conclusion: This study highlights the substantial impact of Communitarian and Apprenticing Affinity, moderated by Managing, on quality and patient safety. Notably, Managing alone lacks direct influence. These findings underscore the significance of cultivating collaborative, learning-oriented environments, alongside effective management practices, to bolster healthcare quality and patient safety.

Arabica coffee is a type of coffee that is widely cultivated in Indonesia. Caffeine is one of the secondary metabolites contained in coffee with various biological benefits. Caffeine belongs to the class of alkaloids of the methylxanthine group. Caffeine is distributed in different parts of the coffee plant in the leaves, cotyledons and flowers. Various studies have proven that the caffeine content in each part of the coffee plant has varying levels. This study aims to determine which part of the Arabica coffee plant comes from Wonolelo, Temanggung with the highest caffeine content.
Powder of flowers, leaves, seeds and fruit skins of Arabica coffee were extracted with distilled water and then extracted liquid-liquid with chloroform, the chloroform fraction obtained was evaporated to form crystals containing caffeine. The results were analyzed quantitatively by UV spectrophotometry. The absorbance results were obtained from UV spectrophotometric readings, then the caffeine content in the sample was calculated and analyzed using SPSS software.
Quantitative test stated that the highest to the lowest caffeine content were fruit peels of 3.232%, seeds (0.771%), flowers (0.509%), and leaves (0.24%). The results of this study are different compared to previous studies. This can occur due to differences in extraction methods, sample age, roasting conditions, grinding degree, geographical origin, such as growing locations at different altitudes, soil types, rainfall, harvest time, and intensity of exposure to sunlight.

Authors: Omigie MI  , Agoreyo FO  
Published: October 2023

Background: Crude acetylene fumes generated from Calcium carbide (CaC2) is one of the most widely used source of acetylene gas for occupational gas welding and as an artificial fruit ripener despite numerous health warnings from the government and health groups in Nigeria.
Aim: The study was aimed at evaluating the effects of crude acetylene on heavy metals present in serum, haematological indices and histology of the lung tissues.
Materials and Methods: Twenty (20) adult male wistar rats were used. The rats were divided into two groups; Group 1 (control) and Group 2 (Test group) (n=10). The animals from the Test group (n = 10) were subsequently exposed to crude acetylene fumes released from the dissolution of 20g of calcium carbide in water for 30 minutes daily for a period of 4 weeks. At the end of the 4th week, the rats were anaesthetized and blood samples were collected for serum heavy metals and haematological analysis and tissues were harvested for histological studies.
Results: a significant increase is seen in serum heavy metals (Cr, Fe and Cd) but no significant difference in Pb in the Test group compared with the control group. Also, there was a decrease in percentage granulocytes and histological results show destruction of respiratory epithelium. Also, there were significant damages to the lung tissues which include mild interstitial haemorrhage, bronchiolar ulceration with luminal debris, interstitial oedema, bronchiolar haemorrhage vascular distortion and congestion.
Conclusion: Exposure to crude acetylene fumes increases serum heavy metals and can cause disruption of the respiratory epithelium

Perception on Preparation for Transplantation and Medication Adherence: An Exploratory Study of Post Kidney Transplant Patients in Nigeria
Authors: Ajah CC  , Ogbo PU  , Akinola AA  
Published: October 2023

Background: Many patients suffering from renal failure have embraced kidney transplant instead of dialysis despite huge financial implications. However, post kidney transplant patients (PKTPs) require strict adherence to immunosuppressant medications to prevent rejection of the allograft. Encounters during patients’ medication refill suggest information gaps about medication use burden.
Objectives: This study was set to explore PKTPs perspective on their preparation for transplant and determine possible information gaps during preparation for transplant.
Methods: This study was conducted by qualitative methods using in-depth interviews. Eighteen PKTPs were purposely recruited from their refill facility in Lagos and interviewed using an open-ended interview guide. The interviews were recorded, transcribed verbatim, coded, and analyzed using thematic analysis.
Findings: The main information received during preparation bordered mostly on expectation of improved quality of life, financial implication, and the need to maintain the new kidney using medications. While some respondents ambiguously stated that the team ‘did their best’ in preparing them for transplant, six respondents regretted not having information about the life-long use of medications until after the transplant. Some respondents totally adhered to their medications, never missing a dose; others missed some doses unintentionally while some others deliberately missed their doses just to save cost. All respondents’ experience of a better quality of life after transplant was as expected.
Conclusion: This study revealed that some respondents experienced information gaps concerning life-long use of medications post-transplant. The experience of very improved quality of life post-transplant seemed to be the driving force for medication adherence.

Published: October 2023

Aim: The aim of this study is to review the histopathological diagnosis of thyroid neoplasms seen in OAUTHC Ile Ife using HBME-1 immunohistochemical marker.
Materials and methods: We studied all thyroid neoplasms diagnosed in the Department of Morbid Anatomy and Forensic Medicine OAUTHC, Ile-Ife from 1st July 1996 to 30th June 2016. We noted the age, sex of the patients, nature of histological diagnosis (benign and malignant) and the specific histologic diagnosis. We evaluated HBME-1 immunostain grade (0, 1+, 2+, 3+, 4+) for all the tumours.
Results: We studied only fifty-six cases (all neoplastic thyroid diseases). Sixteen (28.6%) and forty (71.4%) cases of the cases were benign and malignant, respectively. The Malignant thyroid neoplasms were 2.5 times more frequent than the benign thyroid lesions. There is a significant statistical relationship between HBME-1 expression and the nature of the neoplastic cases (p = 0.001). The sensitivity of HBME-1 in distinguishing benign from malignant thyroid neoplasms in this study was 77.5%, the specificity was 87.5%, the positive predictive value (PPV) was 93.3% and the negative predictive value (NPV) was 60.1%.
Conclusion: There is a significant statistical association between HBME-1 and the nature of thyroid neoplasms. HBME-1 can be used as an added tool in distinguishing malignant thyroid neoplasms from the benign tumours.

Le piège Kariba : une lecture écopoétique du fleuve Zambèze
Authors: Vidotto Margaux 
Published: October 2023

Situé à la frontière entre la Zambie et le Zimbabwe, le barrage de Kariba
surplombe les gorges du même nom (littéralement « petit piège » en tonga)
dans le bassin du Zambèze. Le piège n’est pas qu’étymologique, puisque 57 000 Tongas
ont dû être déplacés, causant aussi bien des bouleversements sociaux que
d’irrémédiables dommages environnementaux. L’étude du barrage, d’un point de vue
écopoétique, associe les transformations de l’espace aux récits qui en découlent.
Les textes que nous choisissons d’étudier se mettent à l’écoute de l’attachement
profond du peuple à son espace, et révèlent les énergies – créatrice, magique et
sociale – qui jouent sous la surface du fleuve Zambèze et au-delà.
Persisting roadblocks in arthropod monitoring using non-destructive metabarcoding from collection media of passive traps

Background
Broad-scale monitoring of arthropods is often carried out with passive traps (e.g., Malaise traps) that can collect thousands of specimens per sample. The identification of individual specimens requires time and taxonomic expertise, limiting the geographical and temporal scale of research and monitoring studies. DNA metabarcoding of bulk-sample homogenates has been found to be faster, efficient and reliable, but the destruction of samples prevents a posteriori validation of species occurrences and relative abundances. Non-destructive metabarcoding of DNA extracted from collection medium has been applied in a limited number of studies, but further tests of efficiency are required with different trap types and collection media to assess the consistency of the method.

Methods
We quantified the detection rate of arthropod species when applying non-destructive DNA metabarcoding with a short (127-bp) fragment of mitochondrial COI on two combinations of passive traps and collection media: (1) water with monopropylene glycol (H2O–MPG) used in window-flight traps (WFT, 53 in total); (2) ethanol with monopropylene glycol (EtOH–MPG) used in Malaise traps (MT, 27 in total). We then compared our results with those obtained for the same samples using morphological identification (for WFTs) or destructive metabarcoding of bulk homogenate (for MTs). This comparison was applied as part of a larger study of arthropod species richness in silver fir (Abies alba Mill., 1759) stands across a range of climate-induced tree dieback levels and forest management strategies.

Results
Of the 53 H2O-MPG samples from WFTs, 16 produced no metabarcoding results, while the remaining 37 samples yielded 77 arthropod MOTUs in total, of which none matched any of the 343 beetle species morphologically identified from the same traps. Metabarcoding of 26 EtOH–MPG samples from MTs detected more arthropod MOTUs (233) than destructive metabarcoding of homogenate (146 MOTUs, 8 orders), of which 71 were shared MOTUs, though MOTU richness per trap was similar between treatments. While we acknowledge the failure of metabarcoding from WFT-derived collection medium (H2O–MPG), the treatment of EtOH-based Malaise trapping medium remains promising. We conclude however that DNA metabarcoding from collection medium still requires further methodological developments and cannot replace homogenate metabarcoding as an approach for arthropod monitoring. It can be used nonetheless as a complementary treatment when enhancing the detection of soft-bodied arthropods like spiders and Diptera.
