The Ventilago Gaertn. (Rhamnaceae) is widely distributed in pantropical areas of Africa, Asia, and Australia. However, fossil records of this taxon are sparse, which limits understanding of the evolution and biogeographic history of the genus. In the present study, we report and describe two new fossil species of Ventilago, V. siwalika sp. nov. from the Miocene sediments of Himachal Pradesh, western Himalaya, and V. pliocenica sp. nov. from the Pliocene sediments of Jharkhand, eastern India based on single‐winged samaras. Ventilago pliocenica is characterized by a prominent midvein, obtuse to sub‐round apex with mucronate tip, longitudinal secondary veins extending the full length of the fruit, and reticulate nature of higher‐order veins, the presence of equatorial rim, the hypanthium, and short pedicel. On the other hand, V. siwalika is characterized by a prominent midvein, obtuse to sub‐round apex with mucronate tip, longitudinal secondary veins extending the full length of the fruit, and reticulate nature of higher‐order veins. Our discovery represents the first unambiguous fossil record of single‐winged samara of Ventilago from India and provides valuable insights into the evolution of this genus. In this paper, we also review its biogeographic history and add new information to understand its hypothetical migration route. Present and earlier records of Ventilago also suggest that this genus was a common forest element during Neogene (Miocene time) in Asia. [ABSTRACT FROM AUTHOR]

Recently, large parts of India and the global South have experienced a rapid transformation from mud to cement houses, which has been promoted by governments and cement companies for its positive impacts on household socioeconomic status and gender inequalities. But we know little else about how different communities are participating in house transformation. In this paper, I study the embodied and affective dimensions of house transformation in Himachal Pradesh, India. I argue that house transformation is also the transformation of traditional gender and caste identities into new middle‐class identities which benefits some social groups, like upper‐caste women and Dalit men, but not others like Dalit women along intersectional lines. My work extends literature in infrastructure studies and urban political ecology by highlighting how the materiality of infrastructures interacts with everyday dimensions of difference to reproduce the marginalisation of historically oppressed groups along intersectional lines of class, caste, and gender.

Rural and remote area electrification is of grave concern around the globe. Therefore, well-planned and cost-effective microgrids integrating renewable energy sources are emerging as effective solutions. However, the microgrid's stable operation and its future deployment is affected by the perturbations caused due to uncertainity in renewable sources, dependency on the battery state of charge, and load variation. So, considering the possible concerns affecting the planning and development of a microgrid for any given region, this paper proposes a comprehensive performance assessment of the hybrid residential microgrid based on a load model of Kibber village in Himachal Pradesh, India. The proposed approach is divided into three parts for the best planning of microgrids. Firstly, the MATLAB–Simulink software technically analyzes the system performance under perturbations considering the available renewable sources. Secondly, an economic analysis using HOMER Pro software is done to examine the cost-effectiveness of the proposed microgrid model through the simulation of electrical loads for Kibber village, considering the available renewable sources. Lastly, a real-time analysis of the proposed prototype of programmable logic controller-based hardware test bench has been developed, aiming for future regional microgrid deployment. System voltage, frequency, power shared, percentage of load met, energy cost, available renewable energy resource, etc. have been considered for validating the proposed controller. The proposed comprehensive assessment of the microgrid model is reproducible with necessary modifications for any geographical location. It will be helpful for its future deployment aiming at rural and remote electrification. [ABSTRACT FROM AUTHOR]

The recent United Nations Educational, Scientific and Cultural Organization (UNESCO) survey states that India has 197 endangered languages. Himachal Pradesh, a state in India, has topped the list with seven definitely endangered languages, and Kinnauri-Pahari being the one. Due to the lack of availability of digitized resources, the corpus compilation is a bit difficult. This paper presents and releases the Kinnauri-Pahari (ISO-639-3:kjo) dataset, consisting of the 43,362 Monolingual and 20,307 Parallel sentences in version_0.1. The dataset was tested on the Statistical, and Neural Machine Translation and their results were evaluated using different evaluation metrics. The corpus is freely available for non-commercial usage and research (https://github.com/phildani7/dlnith/tree/master/Kinnauri-Pahari). [ABSTRACT FROM AUTHOR]

In this paper, a new fuzzy logic (FL) model is proposed for assessing the health status of power transformers. In addition, the detection of incipient faults is achieved where two or more faults exist simultaneously. The process is carried out by integrating a fuzzy logic model with the conventional International Electric Committee (IEC) ratio codes method. As transformer oil insulation deteriorates, excess percentages of dissolved gases such as hydrogen, methane, ethane, acetylene and ethylene are induced within the trasnformer. The status of oil health is generally assessed using these gas concentrations. Therefore, in the proposed model, 31 fuzzy rules are designed based on the severity levels of these gases in order to determine the health index (HI) of the oil. Similarly, any incipient faults along with their severity are also detected using the proposed fuzzy logic model with 22 expert rules. To validate the proposed fuzzy logic model, the data for dissolved gases in 50 working transformers operated by the Himachal Pradesh State Electricity Board (HPSEB), India, are collected. Over the years, calculations for the health index have been performed using conventional dissolved gas analysis (DGA) interpretation methods. The shortcomings of these methods, such as non-reliability and inaccuracy, are successfully overcome using the proposed model. The detection of incipient faults is normally performed using key gas, Rogers ratios, the Duval triangle, Dornenburg ratios, modified Rogers ratios and the IEC ratio codes methods. The shortcomings of these conventional ratio code methods in identifying incipient faults in some typical cases, ie multiple incipient fault cases, are overcome by the proposed fuzzy logic model.

This paper presents a pioneer study on the microbial diversity and antibacterial potential of hive bees (Apiscerana and A.mellifera) honey collected from Himachal Pradesh. In total, 26 bacteria (14 from A.cerana and 12 from A.mellifera) but no fungal isolate were recovered. Bee species and locations comparison in terms of bacterial load (log CFU/g) revealed maximum loads of 3.74 and 3.99 in the honey from A.cerana and Mandi location, respectively. The most prevalent strains (HC3, HC5, HC6, HC8 and HM2) were identified (16S rRNA ribotyping) as Staphylococcushaemolyticus (MT742636), "Bacillussubtilis subsp. stecoris" (MT742637), Bacillussafensis subsp. safensis (MT742638), "Bacilluszanthoxyli" (MT742639) and Bacillussafensis subsp. safensis (MT938911). The apiary honey displayed good to excellent inhibitory activity against Escherichiacoli ATCC1041 whereas, fair to good against Bacillussubtilis ATCC6633, Pseudomonasaeruginosa ATCC10662, Salmonellatyphi NCTC786 and Klebsiellapneumoniae ATCC13883, highlighting its use as a therapeutic agent. Furthermore, it can be effective in minimizing numerous side effects associated with the consumption of synthetic drugs for treating bacterial infections thereby signifying the role of honey as a healthier substitute for synthetic drugs.

The Himalayan foreland basin originated through the India–Asia continent–continent collision driven by downward flexing of the Indian plate. It forms an ideal assemblage to delineate the role of process-controlled sedimentary fill in basin evolution. This paper provides the first comprehensive account of the lithofacies associations and architecture of the Middle Siwalik succession of the Himalayan foreland basin in the south-central Himachal Pradesh sector, India through detailed sedimentological analysis. Eight lithofacies form three distinct sand, gravel, and silt-mudstone lithofacies associations pertaining to specific depositional environments. Architectural elements have been defined together with bounding surfaces separating them. Sedimentological investigations reveal that the Middle Siwalik sequence represents a flash flood dominated piedmont fan and proximal to middle megafan. The fan expansion cycles indicate tectono-climatically controlled sedimentation in the Middle Siwalik foreland basin. Frequent flooding and a high sedimentation rate were influenced by the tectonic uplift along the reactivated thrusts in the hinterland coupled with phases of monsoonal intensification. • The studied Middle Siwalik belongs to a yet unattended Himachal sector of the Indian Himalaya. • Architectural documentation reveals different orders of fluvial hierarchy. • Sedimentation took place in the foreland basin setting solely by continental processes. • Contemporaneous piedmont fan and megafan sedimentary sequences are identified and interpreted. • The Middle Siwalik Foreland Basin of the present study is compared with foreland basins of similar tectonic settings globally.

Large-scale tree planting has been advocated for decades in many countries as a cost-effective strategy to mitigate carbon, rejuvenate degraded landscapes, and support local livelihoods. Recent studies, however, suggest limited ecological and livelihood impacts of tree planting programs, indicating possible limits to tree planting as a natural climate solution. In this paper, we explore these carrying capacity-like limits by evaluating the site suitability of forestry landscapes of the northern Indian state of Himachal Pradesh using theory/expert-based rules and machine learning algorithms. We find that the state can only achieve a maximum of 31.54% forest cover due to socio-ecological and biophysical constraints, much less than India's goal of bringing 66% of the total geographical area of Himalayan states into forest cover. The low availability of suitable lands for growing trees, together with poor plantation site selection by forest range officers limit the use of tree planting as a sole climate mitigation strategy. To approach theoretical planting limits, we propose an ePSA (e-Plantation Site Assistant) recommendation system based on our site-suitability results to assist forest rangers in selecting suitable sites for planting trees. An initial deployment of the recommender system suggests its potential utility in shaping the long-term success of tree plantations as an effective carbon strategy in northern India and beyond. Overall, we argue that there is a need to realign over-ambitious national and international tree planting targets with actual limits from site characteristics to avoid massive wastage of funds and to obtain feasible carbon mitigation outcomes.

India's nearly 1-million strong band of quasi-volunteer accredited social health activists (ASHAs) have been key actors in government efforts to control COVID-19. Utilizing a nationalist rhetoric of war, ASHAs were swiftly mobilized by the government in March 2020 as 'COVID warriors' engaged in tracking illness, disseminating information, and caring for quarantined individuals. The speed at which ASHAs were mobilized into mentally and physically grueling labor was all the more stunning given these minimally paid community health workers have long been seen to have low morale given their precarious, informalized work arrangements. Building on work examining the spatialities of global health governance alongside literature on geographic contingency, this paper explores the ways that nationalist COVID-19 war rhetoric promulgated from Delhi worked as a technology of health governance to propel ASHAs into certain forms of action, yet also opened up spaces of potentiality for them to reimagine their relationship to both the state and the communities they serve. In particular, in our analysis of in-depth telephone interviews with ASHA workers in the state of Himachal Pradesh, we find that their hailing as COVID warriors inspired patriotic calls to duty and legitimized their (long over-looked) roles as critical governance actors, yet also was subject to resistance and reworking due to a combination of institutional histories, local politics, as well as happenstantial everyday encounters of ASHA work. The precarious employment of ASHAs – in terms of basic remuneration as well as the great on-the-job risks that they have faced – underscores both the fragile nature of India's health governance system as well as possible political movements for its renewal. We conclude by calling for geographers to give greater attention to community health care workers as a key window into understanding the uneven ways in which health systems are made manifest on the ground, and their ability to respond to citizens' healthcare needs – both in the COVID-19 pandemic and beyond.
