The Huge volume of urban garbage despite limited space of garbage dump and inappropriate handling have become complicated and never ended problem. Helped to these issue, the research on Forming Ecocement from organic garbage was carried out. Ecocement was made from the mixture of the ash of organic garbage and limestone. The ashing was started by putting up the dry leaves and branches and some anorganic garbage (i.e paper) in pirolisis reactor, heated at temperatures 100, 150, 200, 250, 300 (oC). The resulted ash was mixed with limestone at (60:40) ; (55:45) ; (50:50) ; (45:55) ; (40:60) (%) ratio and blended with water. Next, the mixture was heated in a temperature of 900 oC for 1 hour. The ash analysis from the pirolisis process indicated that the best ash to produce cement was one that was heated in the temperature of 300 oC in the composition of CaO = 200.591,8 ppm SiO2 = 160.020, 8 ppm Al2O3 = 56.800,9 ppm dan Fe2O3 = 5.510,6 ppm, while the best ratio of ash : lime stone is 55 % : 45 % in the composition of CaO=60,8 % , SiO2 = 16,3 % , Al2O3 = 4,8 %, Fe2O3 = 0,3%. The resulted cement stand the tensile strengt 72,6 kg/cm2, min, in 7 days stored (standard  grade of the tensile strengt 150 kg/cm2, min, in 7 days stored).

Generacijska perspektiva digitalne pismenosti u Gani u 21. stoljeću: već zaostali?

This paper investigates the nexus between generations and digital literacy. For the study, simple random sampling was undertaken in selecting 361 respondents, while ten participants were selected through purposive sampling. The authors made use of mixed methods, including the intervju survey method. The data were subjected to bivariate, correlation and thematic analysis. Concerning theresults, younger people turn out to be comparatively more digitally active and more digitally skilled than older people, which is indicative of the fact that there is a generational gap between the two distinct generations in terms of being in a technologically savvy position. This was influenced significantly by the era in which they were born, as each generation comes with its own technological innovations, the phenomena of socialization and social interaction with self-organization as the focus. It is concluded that digital literacy, expositions and exploits are significant in relation to how they shape generational interactions, including the adaptation to digital device utilization in later life.Rad istražuje vezu između različitih generacija i digitalne pismenosti. Za potrebe istraživanja jednostavnim slučajnim uzorkovanjem odabran je 361 ispitanik, dok je 10 ispitanika odabrano namjernim uzorkovanjem. Autori su koristili mješovite metode, uključujući i metodu ankete. Podaci su podvrgnuti bivarijatnim, korelacijskim i tematskim analizama. Rezultati pokazuju da su mlađe osobe digitalno aktivnije i digitalno vještije u usporedbi sa starijima, što ukazuje na postojanje digitalnog jaza između dvije distinktivne generacije kada je riječ o tehnološkim sposobnostima. Na to značajno utječe razdoblje kada su ispitanici rođeni, s obzirom na to da se svaka generacija susreće sa specifičnim tehnološkim inovacijama, socijalizacijskim obrascima i obrascima samoorganizirajuće socijalne interakcije. Zaključuje se da su digitalno opismenjavanje i prakticiranje digitalne pismenosti značajni za oblikovanje generacijskih interakcija, uključujući i prilagodbu na korištenje digitalnih uređaja u starijoj dobi

Caractérisation agronomique de six (6) morphotypes de voandzou (Vigna subterranea L. verdc) cultivés au Niger

Au Niger la diversité du voandzou est peu connue mais la variabilité est assez grande lorsqu’on considère certaines caractéristiques de graines. La présente étude a pour objectif général d’évaluer les performances agro-morphologiques de six (6) morphotypes de voandzou cultivés au Niger afin d’identifier les morphotypes les plus prometteurs sur la base de leurs performances agronomiques et morphologique (coloration des graines). Ces morphotypes ont été choisis à la suite d’une séparation sur la base de leur coloration. Les morphotypes ont ensuite été évalués sur le site expérimental de la Faculté d'Agronomie de l'Université Abdou Moumouni, situé dans la commune 5 de Niamey. Les données ont été collectées à travers un essai agronomique mis en place sur un dispositif de ficher randomiser avec trois (3) blocs, six (6) parcelles élémentaires par bloc. Sept (7) caractères agro morphologiques liés aux composantes du rendement et de la couleur des graines ont été étudiés. L'analyse statistique descriptive a montré que les coefficients de variation vont de 6,5 à 66,3%. L’analyse de la variance a montré des différences significatives entre les morphotypes sur les différents caractères agronomiques. Les variables les plus pertinentes qui permettent de décrire la variabilité entre les groupes des morphotypes étudiés sont le poids de gousses par plante (PG/P), la longueur moyenne de graines par plante (Lmg/P) et la largeur moyenne de graine par plante. (Lamg/P). Ces caractères analysés peuvent ainsi constituer des critères de base pour différencier les morphotypes et servir pour une étude de variabilité entre les morphotypes de voandzou du Niger.   In Niger, the diversity of voandzou is little known but the variability is quite large when certain seed characteristics are considered. The general objective of this study is to evaluate the agro-morphological performance of six (6) morphotypes of voandzou cultivated in Niger in order to identify the most promising morphotypes on the basis of their agronomic and morphological performance (seed coloring). These morphotypes were chosen following a separation on the basis of their coloration. The morphotypes were then evaluated on the experimental site of the Faculty of Agronomy of Abdou Moumouni University, located in commune 5 of Niamey. The data were collected through an agronomic trial set up on a randomized file system with three (3) blocks, and six (6) elementary plots per block. Seven (7) agro morphological characters linked to the components of yield and seed color were studied. Descriptive statistical analysis showed that the coefficients of variation range from 6.5 to 66.3%. The analysis of variance showed significant differences between the morphotypes of the different agronomic characters. The most relevant variables that make it possible to describe the variability between the groups of the morphotypes studied are the weight of pods per plant (PG/P), the average length of seeds per plant (Lmg/P), and the average width of seeds per plant (Lamg/P). These analyzed characters can thus constitute basic criteria to differentiate the morphotypes and serve for a study of variability between the morphotypes of voandzou of Niger

Monitoring Prevalence and Persistence of Environmental Contamination by SARS-CoV-2 RNA in a Makeshift Hospital for Asymptomatic and Very Mild COVID-19 Patients

Objective: To investigate the details of environmental contamination status by SARS-CoV-2 in a makeshift COVID-19 hospital.Methods: Environmental samples were collected from a makeshift hospital. The extent of contamination was assessed by quantitative reverse transcription polymerase chain reaction (RT-qPCR) for SARS-CoV-2 RNA from various samples.Results: There was a wide range of total collected samples contaminated with SARS-CoV-2 RNA, ranging from 8.47% to 100%. Results revealed that 70.00% of sewage from the bathroom and 48.19% of air samples were positive. The highest rate of contamination was found from the no-touch surfaces (73.07%) and the lowest from frequently touched surfaces (33.40%). The most contaminated objects were the top surfaces of patient cubic partitions (100%). The median Ct values among strongly positive samples were 33.38 (IQR, 31.69–35.07) and 33.24 (IQR, 31.33–34.34) for ORF1ab and N genes, respectively. SARS-CoV-2 relic RNA can be detected on indoor surfaces for up to 20 days.Conclusion: The findings show a higher prevalence and persistence in detecting the presence of SARS-CoV-2 in the makeshift COVID-19 hospital setting. The contamination mode of droplet deposition may be more common than contaminated touches

Operation Moonshot: rapid translation of a SARS-CoV-2 targeted peptide immunoaffinity liquid chromatography-tandem mass spectrometry test from research into routine clinical use

OBJECTIVES: During 2020, the UK's Department of Health and Social Care (DHSC) established the Moonshot programme to fund various diagnostic approaches for the detection of SARS-CoV-2, the pathogen behind the COVID-19 pandemic. Mass spectrometry was one of the technologies proposed to increase testing capacity. METHODS: Moonshot funded a multi-phase development programme, bringing together experts from academia, industry and the NHS to develop a state-of-the-art targeted protein assay utilising enrichment and liquid chromatography tandem mass spectrometry (LC-MS/MS) to capture and detect low levels of tryptic peptides derived from SARS-CoV-2 virus. The assay relies on detection of target peptides, ADETQALPQRK (ADE) and AYNVTQAFGR (AYN), derived from the nucleocapsid protein of SARS-CoV-2, measurement of which allowed the specific, sensitive, and robust detection of the virus from nasopharyngeal (NP) swabs. The diagnostic sensitivity and specificity of LC-MS/MS was compared with reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) via a prospective study. RESULTS: Analysis of NP swabs (n=361) with a median RT-qPCR quantification cycle (Cq) of 27 (range 16.7-39.1) demonstrated diagnostic sensitivity of 92.4% (87.4-95.5), specificity of 97.4% (94.0-98.9) and near total concordance with RT-qPCR (Cohen's Kappa 0.90). Excluding Cq>32 samples, sensitivity was 97.9% (94.1-99.3), specificity 97.4% (94.0-98.9) and Cohen's Kappa 0.95. CONCLUSIONS: This unique collaboration between academia, industry and the NHS enabled development, translation, and validation of a SARS-CoV-2 method in NP swabs to be achieved in 5 months. This pilot provides a model and pipeline for future accelerated development and implementation of LC-MS/MS protein/peptide assays into the routine clinical laboratory

Patients with coronary artery disease and diabetes need improved management: a report from the EUROASPIRE IV survey: a registry from the EuroObservational Research Programme of the European Society of Cardiology

BACKGROUND: In order to influence every day clinical practice professional organisations issue management guidelines. Cross-sectional surveys are used to evaluate the implementation of such guidelines. The present survey investigated screening for glucose perturbations in people with coronary artery disease and compared patients with known and newly detected type 2 diabetes with those without diabetes in terms of their life-style and pharmacological risk factor management in relation to contemporary European guidelines. ----- METHODS: A total of 6187 patients (18-80 years) with coronary artery disease and known glycaemic status based on a self reported history of diabetes (previously known diabetes) or the results of an oral glucose tolerance test and HbA1c (no diabetes or newly diagnosed diabetes) were investigated in EUROASPIRE IV including patients in 24 European countries 2012-2013. The patients were interviewed and investigated in order to enable a comparison between their actual risk factor control with that recommended in current European management guidelines and the outcome in previously conducted surveys. ----- RESULTS: A total of 2846 (46%) patients had no diabetes, 1158 (19%) newly diagnosed diabetes and 2183 (35%) previously known diabetes. The combined use of all four cardioprotective drugs in these groups was 53, 55 and 60%, respectively. A blood pressure target of 9.0% (>75 mmol/mol). Of the patients with diabetes 69% reported on low physical activity. The proportion of patients participating in cardiac rehabilitation programmes was low (≈40 %) and only 27% of those with diabetes had attended diabetes schools. Compared with data from previous surveys the use of cardioprotective drugs had increased and more patients were achieving the risk factor treatment targets. ----- CONCLUSIONS: Despite advances in patient management there is further potential to improve both the detection and management of patients with diabetes and coronary artery disease
