Growth, Biomass and Carbon Sequestration Potential of Different Poplar (Populus deltoides Bartr.) clones in Agroforestry System with Wheat (Triticum aestivum) Varieties in tarai belt of Uttarakhand

For two years, field experiments were carried out at Agro-Forestry Research Center of G.B.P.U.A. & T., Pantnagar, Uttarakhand (29°N Latitude, 79°30’ E longitude and at an altitude of 243.84 msl) during 2013-14 and 2014-15, to study the growth, biomass and carbon sequestration potentials of poplar clones in association with different wheat varieties in a sandy loam soil. The soil of the experimental site contained 1.175% of organic carbon, 259, 20 and 195 kg/ha available nitrogen, phosphorus and potassium, respectively. The soil was almost neutral in reaction (pH 8.2). The study was laid in split plot with poplar tree clones viz., S7C8, G-48, W-39 and Kranti in main plots and wheat varieties viz., DBW-17, PBW-502, UP-2748 and HD-2967 in sub-plots. Poplar trees were planted at spacing of 7.0m x 3.0m.Poplar clones S7C8 in 2013-14 and Kranti in 2014-15 recorded higher values of diameter at breast height (DBH) and tree height than clones W-39 and G-48. Wheat variety DBW-17 exhibited higher values of poplar growth than varieties PBW-502 and UP-2748. In 2013-14 clone S7C8 recorded the highest values of different components of trees biomass. In 2014-15, clone Kranti produced significantly higher stem, roots and total biomass than clones G-48 and W-39. The total carbon sequestered by the agroforestry system during both the years, was the highest with the clone Kranti (57.14 t/ha in 2013-14 and 65.69 t/ha in 2014-15). In 2014-15, the total carbon sequestered by clone Kranti was significantly higher than other clones. The total carbon sequestered by the agroforestry system was the lowest with the clone G-48.Except carbon stock in wheat plant biomass, wheat varieties did not affect the poplar growth, biomass and carbon stock of the agroforestry system significantly. Wheat variety DBW-17 in 2013-14 and HD-2967 in 2014-15 recorded the highest amount of carbon in plant biomass

E-service failure and recovery strategy in times of crisis: effect on peer attitudes, expectation and future intention

JEL classification: M0This study analyses the impact of the critical issues on Travel and Tourism e-service failure and explores specifically how peer-to-peer accommodation business can cope with the potential collapse in demand caused by global crises. The purpose is to examine the impact of peer-to-peer accommodation’s recovery offer on revisiting intentions and relationships termination in light of justice-, fairness-, and attribution theory. In this vein, the main aim is to develop a theoretical model which is underpinned by an understanding of the consequences of e-service failure and the effectiveness of recovery strategies for business competitiveness. To gauge peer perceptions of peer-to-peer accommodations, we employed a mixed-method approach. Alongside 17 interviews with peers and industry experts, a survey involving 404 peer-to-peer accommodation users was conducted. Structural equation modelling was applied to unravel the intricate relationships and influences at play. The findings suggest that managers and service providers need to focus on timely recovery and building stronger relationships with peers, to increase repurchase intention and post-recovery satisfaction and to better front the crises times. This could be implemented efficiently via the platform of social media. This study offers specific theoretical and practical implications by providing a fair recovery strategy to result in the satisfaction of both parties.Università degli Studi di Salerno within the CRUI-CARE Agreement

Comparison of wheat yield and soil properties under open and poplar based agroforestry system

Field experiment was conducted during the Rabi season of 2013-14 on an established plantation at old site of Agroforestry Research Centre, Patharchatta of G.B. Pant University of Agriculture and Technology, Pantna-gar, District Udham Singh Nagar, Uttarakhand, India to evaluate the effect of poplar based agroforestry system and open system (without poplar) on yield of different wheat varieties and soil physico-chemical properties.The experi-ment was laid out in randomized block design with 4 treatments and each replicated thrice under both the growing conditions. The crop treatments are wheat varieties viz. UP-2572, PBW-550, DBW-711 and PBW-373. The highest grain yield of all the wheat varieties was obtained under open farming system. Highest grain yield of wheat was rec-orded in UP-2572 (45.3 q/ha) under open farming system. Agroforestry is proven land use system for vertically en-hancing soil health against unsuitable weather condition. The distribution of soil properties was detected from the depth 0-15 cm in poplar based agroforestry system and as well as in open system. During the experiment it was found that agroforestry add more nutrients to the soil compared to open system i.e. highest pH (7.9), EC (0.43 dSm-1), available soil nitrogen (253.48 kg/ha), potassium (219.63 kg/ha) were achieved with UP-2572 while organic car-bon (1.07%) and available soil phosphorus (22.72 kg/ha) were attained with DBW-711

Shopping malls as catalyst for sub-urban development in Ghana

The concentration of population in major cities is usually the consequence of the concentration of employment opportunities, goods and services in such cities. These goods and services act as pull factors to the regional population, especially from the suburban or rural areas, to densely populated cities. The resulting migration creates congestion of all kinds in the cities. Suburban communities are, thus, rendered unattractive for living. This situation is prevalent in Ghana where 75% of migrants into major cities are from suburban areas and the rate of urbanization is 4.1%. Decentralizing amenities to suburban areas would initiate re-distribution of population and thus development. This study investigated the possibility of using the Shopping Mall concept as catalyst to both help develop the suburbia and decongest cities in Ghana. The West Hills Mall at Dunkonah, a suburb near Accra was selected for the study. A mixed research method including  questionnaires, interviews, and observations was used for data collection. Out of a total of 1,642 house owners 328 were sampled and interviewed with questionnaire that delved into their origins, whether they are migrants, and the reasons behind their movement. The study concluded that shopping malls could act as catalysts for development.Keywords: Shopping Malls, Catalyst, Decongestion, Suburbanization, Amenitie

Effect of poplar and eucalyptus based agroforestry system on soil biochemistry

126-130The field experiment was conducted during the winter season of 2016-17 at the experimental site of Agroforestry Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand. Poplar and eucalyptus were intercropped with different wheat varieties (UP-2526, UP-2565, UP-2628, and DPW-621-50). After harvesting the wheat crop, the soil sampling was performed to determine the soil parameters like electrical conductivity (EC), organic carbon and the minerals content. Nitrogen, phosphorus and potassium content and other biochemical constituents were higher in the agroforestry system as compared to the open farming system. A high soil pH (7. 53) was found in an open farming system and lower pH in an agroforestry system. Soil EC in the agroforestry system was slightly higher than the open farming system. Organic carbon was maximum (1. 33%) under the poplar agroforestry system compared to the eucalyptus based agroforestry system. Overall, this study determines the effect of poplar and eucalyptus based agroforestry systems on soil biochemistry

Bidirectional rescue of extreme genetic predispositions to anxiety: impact of CRH receptor 1 as epigenetic plasticity gene in the amygdala

The continuum of physiological anxiety up to psychopathology is not merely dependent on genes, but is orchestrated by the interplay of genetic predisposition, gene x environment and epigenetic interactions. Accordingly, inborn anxiety is considered a polygenic, multifactorial trait, likely to be shaped by environmentally driven plasticity at the genomic level. We here took advantage of the extreme genetic predisposition of the selectively bred high (HAB) and low anxiety (LAB) mouse model exhibiting high vs low anxiety-related behavior and tested whether and how beneficial (enriched environment) vs detrimental (chronic mild stress) environmental manipulations are capable of rescuing phenotypes from both ends of the anxiety continuum. We provide evidence that (i) even inborn and seemingly rigid behavioral and neuroendocrine phenotypes can bidirectionally be rescued by appropriate environmental stimuli, (ii) corticotropin-releasing hormone receptor 1 (Crhr1), critically involved in trait anxiety, shows bidirectional alterations in its expression in the basolateral amygdala (BLA) upon environmental stimulation, (iii) these alterations are linked to an increased methylation status of its promoter and, finally, (iv) binding of the transcription factor Yin Yang 1 (YY1) to the Crhr1 promoter contributes to its gene expression in a methylation-sensitive manner. Thus, Crhr1 in the BLA is critically involved as plasticity gene in the bidirectional epigenetic rescue of extremes in trait anxiety

Association between knowledge of Human Immunodeficiency Virus transmission and consistent condom use among sexually active men in Nigeria: An analysis of 2018 Nigeria Demographic Health Survey

An estimated 1.7 million people were living with HIV in Nigeria in 2020, with over 86,000 people newly infected. Although the global rates of HIV have remained consistent over time, Nigeria has the second-highest number of people living with HIV and contributes to 9% of the global burden of HIV/AIDS. This is due to several structural and individual-level factors that limit knowledge of HIV and condom utilization. In this context, this study examines the association between knowledge about HIV transmission and consistent condom use among sexually active men in Nigeria. The data utilised in this study was sourced from the latest Nigeria Demographic and Health Survey conducted in 2018. The sample included a total of 9,346 men between the ages of 15–59 years who were sexually active at the time of data collection. Frequency distribution, univariate and multivariable analyses were performed at 95% confidence interval and p-value less than 0.05 to determine the association between the key independent variables and covariates. The results showed that 85.03% of sexually active men who had no knowledge of HIV engaged in inconsistent condom use. The key independent variable showed that sexually active men who had knowledge of HIV had higher odds [AOR = 1.37; 95%(CI = 1.10–1.72)] of consistent condom use compared to those without knowledge of HIV. However, sexually active men who were previously married [AOR = 0.38; 95%(CI = 0.24–0.61)], and those residing in the South Eastern region of Nigeria [AOR = 0.62; 95%(CI = 0.44–0.96)] had lower odds of consistent condom use. This study established the association between HIV knowledge and consistent condom use among sexually active males in Nigeria even after controlling for confounders. Educational level, wealth index, and ethnicity are also associated with condom use. This calls for the consideration of social determinants of health, localised and cultural health promotion and targeted public health strategies at all governmental levels to combat the HIV/AIDS epidemic in Nigeria

Influence of Temperature and Humidity on Pregnancy Rate of Murrah Buffaloes under Subtropical Climate

Heat stress has adverse effects on fertility of dairy animals. Decline in fertility is linearly associated with an increase in combination of both temperature and humidity. The purpose of this study was to investigate the relationship between temperature humidity index (THI) and the pregnancy rate of Murrah buffaloes in a subtropical climate. The effects of genetic and non-genetic factors viz., sire, parity, period of calving and age group at first calving were found non-significant on pregnancy rate. The effect of THI was found significant (p<0.001) on pregnancy rate of Murrah buffaloes calved for first time and overall pregnancy rate. The threshold THI affecting the pregnancy rate was identified as THI 75. The months from October to March showed THI<75 and considered as non heat stress zone (NHSZ), while months from April to September were determined as heat stress zone (HSZ) with THI≥75. The lowest overall pregnancy rate (0.25) was obtained in July with THI 80.9, while the highest overall pregnancy rate (0.59) was found in November with THI 66.1. May and June were identified as critical heat stress zone (CHSZ) within the HSZ with maximum decline (−7%) in pregnancy rate with per unit increase in THI. The highest overall pregnancy rate was estimated as 0.45 in NHSZ with THI value 56.7 to 73.2. The pregnancy rate was found to have declined to 0.28 in HSZ with THI 73.5 to 83.7. However, the lowest pregnancy rate was estimated as 0.27 in CHSZ with THI value 80.3 to 81.6
