Sustainability in Business (A critique of environmental sustainability practices in Coca-Cola and Unilever)
Get PDFThe purpose of this paper is to give the reader a clear picture of the importance of sustainability to business, society, and the environment. The author will further discuss how companies can shift their traditional unsustainable production processes to more eco-friendly production processes. Today the world faces numerous issues regarding climate change which are also the result of unsustainable practices by these companies.
In order to see what sustainability means in a real-world sense, the author took two companies, Coca-Cola and Unilever, to study their sustainability approaches. These companies have long histories of financial success but at the same time these companies carry numerous criticisms with their success storie

Supercharged Saroj! Early Literacy Leader Shares Decades of Wisdom
No full textNow retired, early childhood literacy consultant and national trainer and author Saroj Nadkarni Ghoting has spent decades supporting the causes dear to librarians’ hearts. We thought spotlighting her long-time advocacy was well earned.Saroj, you have always supported and promoted diversity in your work; how did this become an important value to you?I guess you could say I was lucky! My father was from India and my mother was the daughter of orthodox Jews from Russia. So, I grew up with multiple languages and cultures in Bethesda, MD, a suburb of Washington, DC.We spoke English at home. My father taught us Marathi before we visited India when I was 12, and my mother read us the postcards in Yiddish she received every day from her mother. Our father told us stories from his childhood, from Hindu works (YAY! Oral storytellling!). My mom read us picture books every day. And we always used our public libraries
Spectrum of Optic Disc Edema with Macular Star and Neuroretinitis – A Literature Review
No full textNeuroretinitis (NR) is a condition characterized by the fundus appearance of optic disc edema and subsequent formation of a macular star figure. What we commonly referred to as NR is now identified to be a clinical presentation in a variety of disorders having both infectious and noninfectious etiologies. The descriptive term optic disc edema with a macular star (ODEMS) better encompasses this heterogeneous group of disorders. During clinics, the ambiguity surrounding terminology, varied presentations, and lacunae in literature prompted us to do this research. We searched through databases such as Google Scholar, PubMed, and directory of open access journals using keywords NR optic disc edema with macular star (ODEMS), cat scratch disease, and selected the high impact original journal articles and review since 1950. The clinical diagnosis is a challenge because these diseases share similar if not identical clinical presentation and laboratory support is often indispensable. The purpose of this review is to provide an approach to a patient having optic disc edema with macular star or ODEMS and NR based on the current understanding of the entity and bring about a consensus regarding its nomenclature

No full textValuing virtue in medicine: a closer look at CanMEDS
Get PDFAbstract
The CanMEDS-2015 Framework outlines seven key roles expected of practicing physicians: communicator, collaborator, manager, health advocate, scholar, and professional. Critics have expressed concern about the omission of a proposed eighth role, ‘Physician as Person’ relevant to humane qualities and personal resilience of the physician. Upon further analyses, the Framework has included several virtuous attributes in the roles of a physician as professional and communicator. However, it addresses certain virtues like creativity, love, and spirituality inadequately. Drawing on literature from Positive Psychology, the author categorizes and additional set of virtues into six classes: wisdom, courage, humanity, justice, temperance, and transcendence. Based on these, the author lists virtues and concepts relevant to a ‘Virtuous Role’ for physicians. The CanMEDS Framework should integrate these virtues as a foundational or overarching role and draw from Virtue Ethics in religious and philosophical traditions. This approach is timely, giving ongoing efforts to update and develop CanMEDS2025. By adopting a Virtuous Role within CanMEDS, we aim to train physicians who are technically skilled and deeply humane, meeting society's expectations for compassionate and virtuous healthcare professional
Characterisation of the impact of dissolved organic matter on iron, manganese, and arsenic mobilisation during bank filtration
No full textBank filtration (BF) has been used for many years as an economical technique for providing high-quality drinking water. However, under anaerobic conditions, the aquifer release of undesirable metal(loid)s, such as iron manganese, and arsenic, reduces the bank filtrate quality and thus restricts the application of this technique. This study investigates the impact of the organic-matter composition of source water on the mobilisation of Fe, Mn, and As during the anaerobic BF process. A laboratory-scale column study was conducted at a controlled-temperature (30 ± 2 °C) using different feed water sources. The organic matter characteristics of the feed water were elucidated using excitation-emission spectroscopy techniques integrated with parallel factor framework clustering analysis (PFFCA) model. The experiment was performed at redox conditions between 66 mv and −185 mv. Moreover, batch studies were implemented to study the effect of natural organic matter type (humic, fulvic and tyrosine) and concentration on the mobilisation of the selected metal(loids). The laboratory experiments demonstrated that the mobilisation of Fe, Mn and As during the BF are varied with the organic water concentration and composition of the source water. The fluorescence results revealed that terrestrial and condensed structure humic compounds are more capable to release Fe into the filtrate water. In contrast, Mn exhibited an equal tendency of mobilisation towards all the humic compounds regardless of its origin and structure. However, at a humic concentration higher than 5 mg-C/L, Mn showed more affinity towards lower molecular weight humic compounds. Arsenic was found to be the least impacted by the alteration in the source water organic matter composition; its mobilisation was highly correlated with iron releasing process. On the other hand, the biodegradable organic matter at high concentration (>10 mg-C/L) was found to be highly effective to turn the infiltration area into Fe-reducing environment and thereby elevating Fe and As concentrations in the pumped water. In conclusion, this study revealed that the DOM composition and concentration of the raw water could play an important role in the mobilisation of metal(loids) during the BF processes.Accepted Author ManuscriptSanitary Engineerin

No full textDensity-Wake of a Charged Particle Moving Through a Plasma
Get PDFThe method developed by the author in a previous paper has been
applied to investigate the density wake created by a moving test particle in tho plasma.
Those wakes are analyzed separately for different harmonics of the cyclotron frequency,
and for small velocity perpendicular to tho applied magnetic field. It is shown that only the
first few harmonics are important to develop the wake in tho plasma
The fate of dissolved organic matter (DOM) during bank filtration under different environmental conditions: Batch and column studies
No full textDissolved organic matter (DOM) in source water highly influences the removal of different contaminants and the dissolution of aquifer materials during bank filtration (BF). The fate of DOM during BF processes under arid climate conditions was analysed by conducting laboratory-scale batch and column studies under different environmental conditions with varying temperature (20-30 °C), redox, and feed water organic matter composition. The behaviour of the DOM fractions was monitored using various analytical techniques: fluorescence excitation-emission matrix spectroscopy coupled with parallel factor analysis (PARAFAC-EEM), and size exclusion liquid chromatography with organic carbon detection (LC-OCD). The results revealed that DOM attenuation is highly dependent (p < 0.05) on redox conditions and temperature, with higher removal at lower temperatures and oxic conditions. Biopolymers were the fraction most amenable to removal by biodegradation (> 80%) in oxic environments irrespective of temperature and feed water organic composition. This removal was 20-24% lower under sub-oxic conditions. In contrast, the removal of humic compounds exhibited a higher dependency on temperature. PARAFAC-EEM revealed that terrestrial humic components are the most temperature critical fractions during the BF processes as their sorption characteristics are negatively correlated with temperature. In general, it can be concluded that BF is capable of removing labile compounds under oxic conditions at all water temperatures; however, its efficiency is lower for humic compounds at higher temperatures.Sanitary Engineerin
