AMBIENT AIR QUALITY AND THE AIR POLLUTION TOLERANCE INDEX OF SOME COMMON PLANT SPECIES OF ANAND CITY, GUJARAT, INDIA
The present study aimed to observe the Air pollution status of Milk city - Anand and its impact on the prevalent vegetation in the Industrial area, Urban area, and Commercial area during a post-monsoon season in 2022. SO2, NO2, NH3, PM2.5, and PM10 were measured using High Volume Air Sampler (HVAS). As we know air pollution is a serious problem in India, more than 90% of India's population lives in places where air quality is below WHO criteria, as it is mixed with road dust, vehicular emission, domestic fuel burning, open waste burning, construction activities, industrial emissions, and anthropogenic activity. Exceeding amounts of gases and particulate matter may lead to various health effects like respiratory infections, Chronic obstructive pulmonary disease (COPD), lung cancer and also affect vegetation. According to the World Health Organization's report(year), exposure to fine particulate outdoor air pollution over a long period causes about 4.2 million premature deaths annually. The concentration of SO2, NO2, NH3, PM2.5, and PM10 varied between 9.31 to 12.16 µg/m3, 7.08 to 10.42 µg/m3, 1.65 to 1.93 µg/m3, 34.75 to 58.30 µg/m3 and 42.90 to 86.64 µg/m3 respectively (Fig. 1). The Air Quality Index (AQI) is a significant tool for measuring ambient air quality and environmental health. AQI ranged from 65.54 to 112.64. The highest AQI recorded was at the industrial site (112.64) and the lowest at Urban site (65.54) (Fig. 2). During the study period, the industrial area was highly polluted due to more release of hazardous gases and particulate matter from various industries. At the commercial and Urban area lower values of AQI represents a satisfactory category as per CPCB. APTI plays a significant role to determine the resistivity and susceptibility of plant species against pollution levels. Plant that has a higher index value are tolerant to air pollution. Fig. 3 shows the APTI for an industrial, urban, and commercial site. All three plant species (Alstonia scholaris, Azardirachta indica and polyalthia longifolia) growing in industrial area showed higher APTI value compared to Urban and Commercial area. The APTI values for plant species were as Alstonia scholaris > Azardirachta indica > polyalthia longifolia. All the species were found in the range of 1-16, hence these species fall under the category of sensitive species.THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.

CHARACTERIZATION OF WASTE IN THE VICINITY OF ANAND DISTRICT, GUJARAT, INDIA
The output of garbage is expanding at an unusual rate as a result of the fast population increase, particularly in emerging nations. Despite the use of incineration and other waste treatment methods, landfills continue to be the most common method of garbage disposal in developing nations. In most cases, financing for proper waste management is minimal, and adoption of more complex waste treatment technology is low. Many landfills are dangerous if they are not properly managed. The purpose of the study was to collect and segregate and manage the garbage as its production is a direct outcome of urbanization, and ineffective waste management poses health risks and affects the urban environment. Therefore, present study aims to generate baseline data for the different types of waste in the vicinity of the Anand district. In this research work, we have categorized waste into two different categories such as biodegradable, non-biodegradable, Recyclable, and Non-recyclable from two dumping sites namely Lambhvel (S1) and Bakrol (S2) of Dist. Anand -The milk city of India which comprises 21,302.43 square meters and 2322.27 square meters area respectively. Each disposal site had a distinct amount of trash covered. The present result revealed the biodegradable waste as 44%, non-biodegradable waste as 56%, recyclable waste as 65% and non-recyclable waste as 35% at Site-1 whereas Site-2 revealed biodegradable, nonbiodegradable, recyclable and non-recyclable waste as 34%, 66%, 64% and 36% respectively. Since there is no waste management system prevalent, the recyclable waste, though in greater proportion is not recycled properly.THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.

Bioregeneration of spent activated carbon: effect of physico-chemical parameters
487-492Microbial regeneration of spent activated carbon
provides an efficient and economic biological treatment process employing
synergic combination of adsorption and biodegradation. Extent of
bioregeneration can be quantified using direct determination of substrate
content on adsorbent, indirect measurement of substrate consumption by
measuring carbon dioxide production and measurement of oxygen uptake.
Bioregeneration is influenced by type of activation of carbon, porosity and
particle size, microbial uptake rate, adsorbate concentration, contact time,
and biodegradability of sorbed compounds. This paper reviews various aspects of
bioregeneration of activated carbon with special reference to its various
governing parameters
CAUSES OF BLINDNESS AND VISUAL IMPAIRMENT AMONG STUDENTS IN INTEGRATED SCHOOL FOR THE BLIND IN BIKANER: BLINDNESS AND VISUAL IMPAIRMENT AMONG BLIND STUDENTS
Objective: The study was performed to identify the causes of blindness and visual impairment among students in integrated schools for the blind in Bikaner. Methods: A cross-sectional study was carried out in the only blind school in Bikaner. The students in the blind school visited were included in the study and informed consents from parents were obtained. Relevant ocular history and basic ocular examinations were carried out on the students of the blind school. Results: A total of 81 students were examined in school of the blind in Bikaner. The main causes of severe visual impairment and blindness in the better eye of students were microphthalmos (25.92%), corneal scar (20.98%), phthisis bulbi (16.04%), retinal dystrophy (8.64%), optic nerve atrophy (8.64%), buphthalmos/glaucoma (6.17%), amblyopia (3.7%), staphyloma (3.7%), cataract (1.23%), anophthalmos (1.23%), aphakia (1.23%), coloboma (1.23%), retinal detachment (1.23%), etc. Of these, 11 (13.58%) students had preventable causes of blindness. Conclusion: It was found that hereditary diseases, corneal scar, glaucoma and cataract were the prominent causes of blindness among the students of blind school. Almost 13.58% of the students had preventable causes, indicating the need of genetical counseling and focused intervention
Inverted and Impacted Third Molars - Report of Two Rare Cases with Literature
Background: Teeth start to erupt during infancy and again when the primary teeth are replaced by the permanent teeth. If a tooth fails to erupt or emerges only partially, it is considered to be impacted. This most commonly happens with the wisdom teeth as they are the last teeth to erupt in the oral cavity between 17 to 21 years. An impacted tooth remains stuck in gum tissue or bone for various reasons as in overcrowded regions were there could be no room for them to emerge or if the jaw is too small to fit the wisdom teeth. Teeth may also become twisted, tilted or displaced as they try to emerge resulting in impaction
Optimizations of Process Parameter for Erosion Wear Using Sustainable Machine Learning Approach
Aim of current study is to utilize different sustainable artificial intelligence (AI) tools to check the influence of test factors on erosion wear. Bottom ash is taken as erodent at different solid concentration while brass is considered as base material. The parameters involved are rotational speed (N), solid concentration (CW), and testing time duration (T). According to experimental results and analysis based on different AI tools , it is abundantly found that erosion wear have a significant dependency on parameters such as N, CW, T and the order of maximum erosion was found as N > CW >T. The rate of rotation speed (N) has been identified as the factor that has the greatest impact on the degree to which erosion wear occur. 3D analysis has been conducted for the maximum and minimum erosion wear condition. In order to verify the accuracy, four distinct methods are utilized; nonetheless, the accuracy of the regression analysis has been found more promising when compared to that of the Ridge, lasso and neural network methodologies
Minimal Hepatic Encephalopathy in Patients with Alcohol Related and Non-alcoholic Steatohepatitis Related Cirrhosis by Psychometric Hepatic Cephalopathy Score and Critical Flicker Frequency
Background: alcohol may have additional neurotoxic ill-effects in patients with alcohol related cirrhosis apart from hepatic encephalopathy. We aimed to evaluate minimal hepatic encephalopathy (MHE) with Psychometric Hepatic Encephalopathy (PHES) score and Critical Flicker Frequency (CFF) in alcohol (ALD) and non-alcoholic steatohepatitis related (NASH) related cirrhosis. Methods: 398 patients were screened between March 2016 and December 2018; of which 71 patients were included in ALD group and 69 in NASH group. All included patients underwent psychometric tests which included number connection test A and B (NCT-A and NCT-B), serial dot test (SDT), digit symbol test (DST), line tracing test (LTT) and CFF. MHE was diagnosed when their PHES was <-4. Results: the prevalence of MHE was significantly higher in ALD group compared to NASH (69.01% vs 40.58%; P=0.007). The performance of individual psychometric tests was significantly poorer in ALD (P<0.05). Overall sensitivity and specificity of CFF was 76.62% (95%CI 65.59 – 85.52) and 46.03% (95%CI 33.39 – 59.06) respectively. Mean CFF was significantly lower in ALD than NASH (37.07 (SD 2.37) vs 39.05 (SD 2.40), P=0.001); also in presence of MHE (36.95 (SD 2.04) vs 37.96 (SD 1.87), P=0.033) and absence of MHE (37.34 (SD 3.01) vs 39.79 (SD 2.46), P=0.001). Conclusion: MHE is significantly more common in patients with ALD cirrhosis than NASH counterparts. Overall CFF values are less in alcohol related cirrhosis than NASH related cirrhosis, even in presence or absence of MHE. We recommend additional caution in managing MHE in ALD cirrhosis
Visible light-driven photocatalysts, quantum chemical calculations, ADMET-SAR parameters, and DNA binding studies of nickel complex of sulfadiazine
Abstract A 3D-supramolecular nickel integrated Ni-SDZ complex was synthesized using sodium salt of sulfadiazine as the ligand and nickel(II) acetate as the metal salt using a condensation process and slow evaporation approach to growing the single crystal. The metal complex was characterized for its composition, functional groups, surface morphology as well as complex 3D structure, by resorting to various analytical techniques. The interacting surface and stability as well as reactivity of the complex were carried out using the DFT platform. From ADMET parameters, human Intestinal Absorbance data revealed that the compound has the potential to be well absorbed, and also Ni-SDZ complex cannot cross the blood–brain barrier (BBB). Additionally, the complex's DNA binding affinity and in-vivo and in-vitro cytotoxic studies were explored utilizing UV–Vis absorbance titration, viscosity measurements, and S. pombe cells and brine shrimp lethality tests. In visible light radiation, the Ni-SDZ complex displayed exceptional photo-degradation characteristics of approximately 70.19% within 70 min against methylene blue (MB)
