A factor-cluster approach in assessing residents' perceptions towards sustainable rural tourism development
(Revista Latino-Americana de Turismologia, 2024-10-25) Gaonkar, Sadanand; Sukthankar, Sitaram V.
Rural tourism is now widely embraced and has given rural residents numerous recreational business opportunities to engage in tourism globally. Therefore, they are required to investigate even on a lesser scale. In this regard, a study was conducted to ascertain how locals view sustainable rural tourism development and how these perceptions vary across various demographic categories. The data was gathered from 300 randomly selected Dharbandoda Taluka, Goa, India residents and analyzed using descriptive statistics, Exploratory Factor Analysis (EFA), and Cluster Analysis. The EFA revealed the five main factors, namely, the public utility services factor, economic factors, social factors, cultural factors, and environmental factors. The factor-cluster analysis results identified the three main clusters: Socio-Environmental, Socio-Economic, and Socio-Cultural Focused. It is revealed that cluster 3 has more respondents who are female, ages between 18 to 25, single, and employed, and have favorable attitudes toward the sustainable development of rural tourism. The study concludes that the region will experience significant growth if more local and natural resources are utilized efficiently.

Coastal Regulation Zone and Human Intervention: A Case Study of Salcete Taluka, Goa, India
(National Association of Geographers India (NAGI), 2024) Deshpande, Tanvi; Pardeshi, Sudhakar
Coasts are the zone of various importance both naturally and economically. Goa is a famous tourist destination where most of the tourism is concentrated in the coastal areas. Though, it has economically benefited State’s economy but on the other hand, has given rise to haphazardous development within the coastal regulation zone which is threatening the fragile coastal ecosystem. The present study has attempted to highlight the human intervention along the coastal zone of Salcete taluka in South district of Goa. To study the human interference along the coast, two methods were implemented: i) sand dune profiling using dumpy level and ii) shoreline change analysis in Arc GIS software. About 14.65 km length of the shoreline of Salcete taluka shows accretion at Utorda, patches between Betalbatim and Colva, Sernabatim and Benaulim, Mobor and Betul. While 12.35 km length of the shoreline shows erosion along the beaches of Betalbatim, Colva, Benaulim, Varca and Cavelossim. Erosion might be associated with the interference of human in form of tourism and other activities taking place along the beach. The overall study stresses upon the problems due to human intervention and urgent need to formulate rules and policies to regulate, prevent and restore the fragile coastal ecosystem from further devastation.

(European Chemical Bulletin, 2014) Borker, Vrinda; Mordekar, Rajashri Karmali; Rane, Koyar
Textile effluent containing unused dye when released in surroundings pollutes water bodies. It requires processing before disposal. Iron ore reject created during mining creates environmental pollution but contains minerals of technological importance. It has ~30-50 % iron in the form of γ-Fe2O3, α-Fe2O3 and Fe3O4 is wasted if thrown in fields, so can be used to degrade organic dyes. Mineralization of methylene blue, MB a model dye is carried out using photocatalyst either iron ore reject, synthesized ZnO or ZnO1-xNx and the results are compared. ZnO is synthesised from oxalate and nitrogen doped ZnO from hydrazinated oxalate precursors. FTIR study of zinc complexes indicates formation of precursors and XRD of decomposed complexes reveal formation of zinc oxide with wurtzite structure. The presence of nitrogen in ZnO1- xNx is confirmed by chemical estimation and XPS studies. SEM reveals the particle size of ZnO1-xNx ~69 nm and ZnO ~0.5-1μm. ZnO1-xNx absorbs in the visible region and ZnO in UV region. Band gap energy calculated using Diffuse reflectance Spectrum is 2.48 eV for the former, 3.19eV for the later and 2.38 eV for ore reject. Mineralizing property of ore reject, ZnO and ZnO1-xNx are compared by electrons spray ionisation mass spectrometry study (ESI-MS) of degradation products, COD measurement and CO2, NO3- and SO4-2 estimation. Reusability study, kinetic study of degradation of MB dye using photocatalysts and ESI-MS study of degraded products of MB reveal better efficacy of iron ore rejects amongst three. Thus efficiency of iron ore reject > ZnO1-xNx. > ZnO as photocatalyst.

(Elsevier, 2023) Vernekar, Beena K.; Kotkar, Gayatri D.; D'souza, Luann R.; Hathwar, Venkatesha R.; Dhuri, Sunder N.
Solvothermal condensation of 4-hydroxy-3-methoxy benzaldehyde and ethylenediamine resulted in single crystals of the novel Schiff base N,N'-Bis(4-hydroxyl-3-methoxybenzylidene)ethane-1,2-diamine (H2L) while the conventional method yielded microcrystalline H2L. Single crystals of H2L were characterized by various techniques, including single crystal X-ray diffraction. The structural analysis revealed crystallization of H2L in the monoclinic P21 space group with z = 4 and z′ = 2 indicating the presence of two independent H2L molecules in the asymmetric unit of the crystal structure connected by O6-H6…N2 weak contacts involving H and N atoms of the hydroxyl and amine groups respectively. The biological activities, namely DNA binding and cell viability studies of H2L, were performed. H2L exhibited potent activity against mushroom tyrosinase enzyme. In this work, in-silico docking studies have been conducted to evaluate the effective binding modes of H2L with 2y9x mushroom tyrosinase protein. The docking studies revealed minimum binding energy of -6.43 kcal mol−1 for H2L compared to the value of -3.64 kcal mol−1 for standard Kojic acid. The antibacterial performance of H2L was tested, and the results are presented.
C–H hydrogen bond and halogen bond directed self-assembly of ethereal podands and C–X⋯F−/HF2− halogen bonding in solution
(Royal Society of Chemistry, 2023) Dutta, Dipjyoti; Gogoi, Anamika; Dutta, Rupjyoti; Harmalkar, Sarvesh S.; Lama, Prem; Dey, Sandeep Kumar
A series of halogenated podands (P1–P8) have been synthesized from 1,3,5-tris(bromomethyl)mesitylene and halogen-substituted phenols to study the structure-directing roles of C–H hydrogen bonds and halogen bonds in the formation of self-assembled supramolecular frameworks. The ethereal podands are suitable for the study of C–H hydrogen bonds in the crystalline state due to the presence of three different types of C–H donors, such as methyl, methylene, and aromatic –CH groups, and three different types of acceptors such as ethereal oxygen, halogens, and aromatic rings. Single crystal X-ray structures of three halophenyl-functionalized podands (P2, P3 and P4) and a cyanophenyl-functionalized podand (P9) were determined at room temperature (298 K), and detailed Hirshfeld surface analysis of the crystal structures was performed to quantify the close contact contributions (in %) from different types of non-covalent interactions involved in the self-assembly of podands. The crystal structures of the halophenyl-functionalized podands (P2, P3, and P4) showed self-assembly primarily via intermolecular C–H⋯O, C–H⋯π, and halogen bonding interactions. Hirshfeld surface analysis of the crystal structures revealed significantly higher contributions from H⋯C and H⋯X (X = halogen) close contacts in comparison to H⋯O and X⋯C close contacts in 2D-fingerprint plots. The self-assembly of the cyanophenyl-functionalized podand (P9) was largely governed by intermolecular C–H⋯O and C–H⋯N interactions. The podand crystals showed relatively high thermal stability in thermogravimetry analysis (250–290 °C), which can be attributed to the hydrogen and halogen bond assisted formation of 3D supramolecular frameworks. 19F-NMR spectra of tetraethylammonium fluoride in the presence of an equivalent amount of tris(2-halophenoxymethyl)mesitylene podand (P5 or P6) showed a downfield shift of the fluoride signal (Δδ 3.2 ppm) indicating C–X⋯F− halogen bonding in solution. Further, 19F-NMR spectra of hydrogen bifluoride (HF2−) in the presence of P5 or P6 showed a large upfield shift of ≈21–22 ppm suggesting C–X⋯F−⋯H–F halogen bonding in solution.
D.C. conductivity behaviour of poly(vinyl alcohol)-based ferrogels: role of borax and carbonyl iron
(Springer Nature, 2019) Lawrence, Mathias B.; Joseph, Jaison; Phondekar, Karesh; Moodi, Kiran
The d.c. conductivity of poly(vinyl alcohol) hydrogels and ferrogels, cross-linked with borax, has been studied using two-probe resistance measurement method as a function of cross-linker and dopant concentrations. The availability of charge carriers (i.e. unbound borate ions and free sodium ions) in these matrices is seen to vary with cross-linker and dopant concentrations. Increase in borax concentration leads to the rise in d.c. conductivity values. Enhancement in the carbonyl iron dopant proportions, at unchanged borax concentrations, causes a decrease in the conductivity. This behaviour is explained on the basis of structural modifications introduced within the network matrix owing to the variations in cross-linker and dopant concentrations.

(John Wiley & Sons, 2023) Sung, Kisu; Hyeon, Seokhwan; Kim, Minjae; Sahu, Pramod K.; Naik, Siddhi D.; Aswar, Vikas R.; Tripathi, Sushil K.; Chang, Tong-Shin; Ahn, Jin-Hyun; Yu, Jinha; Jeong, Lak Shin
MLN4924 is known for its potential in cancer treatment and antiviral activity as a NEDD8-activating enzyme (NAE) inhibitor. We designed and synthesized fluorinated MLN4924 derivatives by electrophilic fluorination at the 6′-position and nucleophilic fluorination at the 2′-position of the sugar moiety, respectively. The compounds were then evaluated for their anti-HCMV activity, and compound 2 a exhibited the most potent HCMV inhibitory activity, showing similar results to MLN4924 but with no toxicity at a high concentration. Docking studies highlighted the importance of the sugar conformation in the binding interaction with the target protein. This research offers critical insights into the optimization of MLN4924 derivatives and provides a promising pathway towards the development of effective antiviral agents.
