Phosphate adsorption from aqueous solution using electrospun cellulose acetate nanofiber membrane modified with graphene oxide/sodium dodecyl sulphate

Eutrophication and water pollution caused by a high concentration of phosphate are two concerning issues that affect water quality worldwide. A novel cellulose-based adsorbent, cellulose acetate/graphene oxide/sodium dodecyl sulphate (CA/GO/SDS), was developed for water treatment. A 13% CA solution in a mixture of acetone:dimethylacetamide (2:1) has been electrospun and complexed with a GO/SDS solution. The field emission scanning electron microscope (FESEM) showed that the CA membrane was pure white, while the CA/GO/SDS membrane was not as white as CA and its colour became darker as the GO content increased. The process of phosphate removal from the solutions was found to be aided by the hydroxyl groups on the surface of the CA modified with GO/SDS, as shown by infrared spectroscopy. An optimization condition for the adsorption process was studied by varying pH, immersion time, and the mass of the membrane. The experimental results from phosphate adsorption showed that CA/GO/SDS had an excellent pH adaptability, with an optimum pH of 7, and maximum removal (>87.0%) was observed with a membrane mass of 0.05 g at an initial concentration of 25 mg L−1 . A kinetic study revealed that 180 min of contact time could adsorb about 87.2% of phosphate onto the CA/GO/SDS membrane. A typical pseudo-second-order kinetic model successfully portrayed the kinetic sorption of phosphate, and the adsorption equilibrium data were well-correlated with the Langmuir adsorption model, suggesting the monolayer coverage of adsorbed molecules

Sanitation, water, energy use, and traffic volume affect environmental quality: Go-for-green developmental policies

Carbon emissions are primarily the result of human activity in urban areas. Inadequate sanitary facilities, contaminated drinking water, nonrenewable energy, and high traffic congestion have all impacted the natural ecosystem. Using data from 1975 to 2019, the study assessed the impact of the aforementioned variables on Pakistan’s carbon emissions in light of this crucial fact. The ARDL cointegration method was used to estimate the short- and long-run parameter estimates. Urban sanitation challenges and energy consumption increase carbon emissions, which affects the natural environment by raising a country’s carbon intensity. Economic expansion confirmed the inverted U-shaped relationship between carbon emissions and economic growth to verify the Environmental Kuznets Curve (EKC) hypothesis in the long run. In contrast, the monotonically rising function of carbon emissions provides evidence of the nation’s economic development in the short run. Access to clean drinking water improves population health and encourages the purchase of eco-friendly products. The government must improve sanitation services and use renewable energy sources to enhance air quality. © 2022 Khalil et al.

Gender differentials in the evolution of cigarette smoking habits in a general European adult population from 1993–2003

BACKGROUND: Describe the recent evolution of cigarette smoking habits by gender in Geneva, where incidence rates of lung cancer have been declining in men but increasing in women. METHODS: Continuous cross-sectional surveillance of the general adult (35–74 yrs) population of Geneva, Switzerland for 11 years (1993–2003) using a locally-validated smoking questionnaire, yielding a representative random sample of 12,271 individuals (6,164 men, 6,107 women). RESULTS: In both genders, prevalence of current cigarette smoking was stable over the 11-year period, at about one third of men and one quarter of women, even though smoking began at an earlier age in more recent years. Older men were more likely to be former smokers than older women. Younger men, but not women, tended to quit smoking at an earlier age. CONCLUSION: This continuous (1993–2003) risk factor surveillance system, unique in Europe, shows stable prevalence of smoking in both genders. However, sharp contrasts in age-specific prevalence of never and former smoking and of ages at smoking initiation indicate that smoking continues a long-term decline in men but has still not reached its peak in women

The pandemic toll and post-acute sequelae of SARS-CoV-2 in healthcare workers at a Swiss University Hospital.

Healthcare workers have potentially been among the most exposed to SARS-CoV-2 infection as well as the deleterious toll of the pandemic. This study has the objective to differentiate the pandemic toll from post-acute sequelae of SARS-CoV-2 infection in healthcare workers compared to the general population. The study was conducted between April and July 2021 at the Geneva University Hospitals, Switzerland. Eligible participants were all tested staff, and outpatient individuals tested for SARS-CoV-2 at the same hospital. The primary outcome was the prevalence of symptoms in healthcare workers compared to the general population, with measures of COVID-related symptoms and functional impairment, using prevalence estimates and multivariable logistic regression models. Healthcare workers (n=3,083) suffered mostly from fatigue (25.5%), headache (10.0%), difficulty concentrating (7.9%), exhaustion/burnout (7.1%), insomnia (6.2%), myalgia (6.7%) and arthralgia (6.3%). Regardless of SARS-CoV-2 infection, all symptoms were significantly higher in healthcare workers than the general population (n=3,556). SARS-CoV-2 infection in healthcare workers was associated with loss or change in smell, loss or change in taste, palpitations, dyspnea, difficulty concentrating, fatigue, and headache. Functional impairment was more significant in healthcare workers compared to the general population (aOR 2.28; 1.76-2.96), with a positive association with SARS-CoV-2 infection (aOR 3.81; 2.59-5.60). Symptoms and functional impairment in healthcare workers were increased compared to the general population, and potentially related to the pandemic toll as well as post-acute sequelae of SARS-CoV-2 infection. These findings are of concern, considering the essential role of healthcare workers in caring for all patients including and beyond COVID-19

KEPEMIMPINAN PROFETIK DAN KEPEMIMPINAN DEMOKRATIK PANCASILA DALAM PERSPEKTIF ISLAM

ABSTRAK Setiap lembaga atau organisasi termasuk di dalamnya pendidikan seperti sekolah atau madrasah sangat membutuhkan kehadiran seorang pemimpin. Madrasah sebagai lembaga pendidikan Islam bertujuan membentuk manusia yang berkepribadian, mengembangkan intelektual peserta didik dalam rangka mencerdaskan kehidupan bangsa. Satu penyebab makin menurunnya mutu pendidikan madrasah di Indonesia adalah kurangnya profesionalisme para kepala madrasah sebagai pemimpin pendidikan di tingkat lapangan. Tujuan penelitian ini untuk menggali konsep tentang kepemimpinan profetik dan kepemimpinan demokratik Pancasila dalam perspektif Islam ditinjau dari kepemimpinan Nabi Muhammad SAW di lembaga pendidikan Madrasah. Metode penelitian menggunakan kualitatif dengan pendekatan deskriptif. Metode pengumpulan data yang digunakan adalah metode dokumentasi berupa buku-buku, disertasi, tesis, majalah, jurnal, atau lainnya yang membahas dan mengulas tentang permasalahan penelitian. Kepemimpinan profetik dalam perspektif Islam di lembaga pendidikan madrasah menerapkan konsep prophetic leadership dalam kepemimpinannya dengan menekankan pada keempat sifat-sifat nabi, yaitu: siddiq, amanah, tabligh, dan fathanah. Kepemimpinan demokratik Pancasila dalam perspektif Islam di lembaga pendidikan madrasah dimana dalam konsep kepemimpinan yang demokratis Kepala madrasah harus melakukan dua fungsi kepemimpinan, yaitu manajer dan koordinator yakni segi nilai- nilai kebenaran dan keyakinan dalam menjalankan kepemimpinan dalam sebuah organisasi. Kepemimpinan Demokratik Pancasila Dalam perspektif Islam ialah kepemimpinan yang dibangun dan dipraktikkan berdasarkan hikmat (ﺔﻤﻜﺣ) / kebijaksanaan. Dimana hikmat ( ﺔﻤﻜﺣ ) itu ialah ilmu kenabian dan kesempurnaan ilmu yang dapat memahami alquran dan sunnah secara mendalam sehingga dapat membedakan yang haq dan yang batil, dengan demikian berarti sebangun dengan makna profetik (kenabian) itu sendiri. Kepemimpinan demokratik Pancasila yang berlandaskan kepada Ketuhanan, kemanusiaan, persatuan, permusyawaratan dan hikmah serta menjunjung tinggi keadilan ialah merupakan sintesa dari kepemimpinan profetik dengan kepemimpinan demokratik (liberal). Kata Kunci: Kepemimpinan Profetik, Kepemimpinan Demokratik Pancasila, Pendidikan Madrasah. vii ABSTRACT Every institution or organization, including schools or madrasahs, really needs a leader's presence as Islamic educational institutions aim to shape human personalities and develop intellectual students to educate the nation's life, Madrasas. Where one of the causes of the decreasing quality of schooling in Indonesia is the lack of professionalism of school principals as education managers at the field level. This research explores the concept of prophetic leadership and democratic leadership from an Islamic perspective in terms of the direction of the Prophet Muhammad in Madrasah educational institutions. The research method used qualitative with a descriptive approach. The data collection method used is the documentation method in the form of books, dissertations, theses, magazines, journals, or others that discuss and review research problems. Prophetic leadership from an Islamic perspective in madrasah educational institutions applies the concept of prophetic leadership in its direction by emphasizing the four characteristics of the Prophet: Siddiq, Amanah, Tabligh, and Fathanah. Pancasila democratic leadership in an Islamic perspective in madrasah educational institutions wherein the concept of democratic leadership the head of the madrasah must perform two leadership functions, namely manager and coordinator, namely in terms of truth values and beliefs in carrying out administration in an organization. Pancasila Democratic Leadership From an Islamic perspective, leadership is built and practiced based on wisdom (ﺔﻤﻜﺣ) / wisdom. Where wisdom ( ﺔﻤﻜﺣ) is prophetic knowledge and the perfection of knowledge that can understand the Qur'an and sunnah in depth so that it can distinguish between Haq and vanity, thus meaning it is congruent with the prophetic meaning (prophetic) itself. Pancasila democratic leadership which is based on divinity, humanity, unity, deliberation, wisdom, and upholds justice is a synthesis of prophetic leadership with democratic (liberal) leadership.
