Abstract: This clinical record revisits the classical and pathognomonic features of craniocervical tetanus in a 65-year-old farmer who presented with acute-onset trismus, multiple cranial nerve pareses (III, IX, and X), risus sardonicus, and spasm of the head-neck ...

Abstract	This clinical record revisits the classical and pathognomonic features of craniocervical tetanus in a 65-year-old farmer who presented with acute-onset trismus, multiple cranial nerve pareses (III, IX, and X), risus sardonicus, and spasm of the head-neck musculature. This paper explores the relevant literature and presents a brief pictorial analysis of the global epidemiologic data. With most countries successfully adopting the maternal and neonatal tetanus elimination (MNTE) program, the incidence and mortality of tetanus across age groups have sharply reduced in high-income and most middle-income nations. In adults, tetanus is now encountered in specialized situations like waning immunity and incomplete vaccination, in the resource-poor and low-income nations, in countries achieving MNTE recently, and as cluster cases in the aftermath of natural disasters involving human settlements. Therefore, present-day practicing otolaryngologists and residents who have limited exposure to the tell-tale clinical features of craniocervical tetanus should consider it during work-up of acute-onset trismus in adults in susceptible situations and with a conducive background. The clinical spectrum of craniocervical tetanus as depicted in this report, including the demonstration of the pathognomonic positive spatula test, provides valuable learning points for otolaryngologists in this regard.

Abstract	Dual practice, where physicians work both in public and private hospitals, is a widely observed phenomenon, particularly in developing countries. This paper studies a multi-stage game where hospitals compete for physicians as well as patients and, the service provided by physicians endogenously depends on the competitive setting in which hospitals operate. Specifically, we examine the impact of allowing dual practice on hospital payoffs, physician's service and societal welfare. We find that dual practice is socially desirable, since it softens the competition for physician's exclusive service while also increasing the amount of their service. However, if the degree of competition between the hospitals is significant, dual practice may not yield the highest payoffs for both public and private hospitals.

Abstract	Unlike the conventional model of transition metal catalysis, ligands in metal-ligand cooperative (or bifunctional) catalysis are involved in the substrate activations. Such processes have offered unique mechanistic understandings and led to new concepts for the catalyst design. In particular, unprecedented activities were discovered when the ligand could undergo dearomatization-rearomatization reactions during the catalytic cycle. Aromatization can provide an extra driving force to thermodynamics; consequently, it brings a new perspective to ligand platform design for catalysis. While numerous applications were demonstrated, the influences of changing ligand aromatic properties were often overlooked. In this article, representative ligand systems will be highlighted and a comparison between the Milstein and the Huang pincer systems will be discussed to provide theoretical and conceptual insights.

Abstract	The study examines acoustic correlates of the four-way laryngeal contrast in Marathi, focusing on temporal parameters, voice quality, and onset f0. Acoustic correlates of the laryngeal contrast were investigated in the speech of 33 native speakers of Marathi, recorded in Mumbai, India, producing a word list containing six sets of words minimally contrastive in terms of laryngeal specification of word-initial velar stops. Measurements were made for the duration of prevoicing, release, and voicing during release. Fundamental frequency was measured at the onset of voicing following the stop and at 10 additional time points. As measures of voice quality, amplitude differences between the first and second harmonic (H1-H2) and between the first harmonic and the third formant (H1-A3) were calculated. The results demonstrated that laryngeal categories in Marathi are differentiated based on temporal measures, voice quality, and onset f0, although differences in each dimension were unequal in magnitude across different pairs of stop categories. We conclude that a single acoustic correlate, such as voice onset time, is insufficient to differentiate among all the laryngeal categories in languages such as Marathi, characterized by complex four-way laryngeal contrasts. Instead, a joint contribution of several acoustic correlates creates a robust multidimensional contrast.

Abstract	The first incident of COVID-19 case in India was recorded on 30th January, 2020 which turns to 100,000 marks on May 19th and by June 3rd it was over 200,000 active cases and 5,800 deaths. Geographic Information System (GIS) based spatial models can be helpful for better understanding of different factors that have triggered COVID-19 spread at district level in India. In the present study, 19 variables were considered that can explain the variability of the disease. Different spatial statistical techniques were used to describe the spatial distribution of COVID-19 and identify significant clusters. Spatial lag and error models (SLM and SEM) were employed to examine spatial dependency, geographical weighted regression (GWR) and multi-scale GWR (MGWR) were employed to examine at local level. The results show that the global models perform poorly in explaining the factors for COVID-19 incidences. MGWR shows the best-fit-model to explain the variables affecting COVID-19 (R2= 0.75) with lowest AICc value. Population density, urbanization and bank facility were found to be most susceptible for COVID-19 cases. These indicate the necessity of effective policies related to social distancing, low mobility. Mapping of different significant variables using MGWR can provide significant insights for policy makers for taking necessary actions.

Abstract	Nano-sized particles in wastewater are generally considered colloids, but their production and size distribution are not well understood. Organic nano-sized particles are more abundant than engineered nanomaterials in wastewater, where they may cause membrane fouling, harbor pathogens, and transport contaminants to the environment. To our knowledge, this study is the first to examine the seasonal behavior, removal, and the quantity and size of suspended particles (both unfiltered and filtered through a 450 nm filter) at multiple points within different processes along two water resource recovery facilities (WRRFs, formerly wastewater treatment plants). In Southern California where wastewater is often reused or reclaimed, a better understanding of nano-sized particles generation and removal may help reduce cost. We found that both types of the biological secondary treatments investigated (conventional activated sludge process and trickling filter) were more efficient in removing suspended particles larger than 450 nm than they were smaller ones. However, the results show that current treatment processes are not designed to remove nano-sized particles efficiently. We also investigated the factors that correlate with their occurrence and found that there was a significant and direct correlation between influent dissolved chemical oxygen demand (COD) and the abundance of suspended particles both larger and smaller than 450 nm, suggesting that the suspended particles increased with dissolved COD in the WRRFs and thus were biogenically generated during the wastewater treatment. Although no conclusive seasonal correlations were found, dissolved COD management may control nano-sized particle production. PRACTITIONER POINTS: Conventional secondary treatments (activated sludge and trickling filter) could efficiently remove particles but not as efficiently for nano-sized particles (40.1-52.7% removal). At one facility, particles of all sizes were found to correlate with dissolved carbon and EPS, meaning they were biogenic. Monitoring dissolved carbon or EPS precursors may help control membrane fouling post-secondary treatment, and this warrants more studies.

Abstract	The term peri-urban can be defined as the settlements beyond, about or around core cities. It has often observed that the areas congested with the core city are enjoying some basic facilities/amenities as urban entity whereas the areas beyond the city are lagging behind. Thus the uneven distribution of amenities increases the inequality from core to peripheries. These heterogeneous characteristics within a city and around its periphery increase the inequalities which are characterized by the formation of sub-city typologies within the city and its peripheral settlements. The goal of this study is to explore extent and magnitude of spatial inequality in levels of living and the resultant sub-city typologies of English Bazar city and its peri-urban settlements, one of the most dynamic urban agglomerations of West Bengal. Village level House listing and housing data from the 2011 census are used here to find out the magnitude of inequality and construct sub-city typologies. 19 variables from the census are selected to represent three broad class of attributes such as housing quality, access to amenities and availability of household assets through different standardize indices for developing sub-city typology. Hierarchical and non-hierarchical cluster analysis methods are then used to identify empirical typologies considering relevant principal factors from PCA analysis. It identifies a five cluster solution corresponds to five spatial typological categories (High SE-Area, Average SE-Area, Good SE-Area, Average Area, Low socio-economic area). Identification of five spatial typological categories helps to explore the urban inequality at micro level for English Bazar Urban Agglomeration and its peri-urban settlements. The result also shows that settlements lying contiguous to the Old Malda city are deprived in asset holding and household quality whereas the peripheral settlements lying along English Bazar city have better standard of living conditions.
