Abstract

The southern tip of the Thal desert in Pakistan harbors the remnants of the original tropical thorn forest, amounting to two percent, which covered the province of Punjab a hundred years ago. In the past three decades, there has been a progressive decline in woody species cover on dunes, which is directly related to the increase in population in the surrounding area. Stabilized and destabilized dunes were subjectively selected followed by quantification of cover and diversity of woody species on the top and lower slopes. Dunes closely resembling the overall cover were grouped to suggest corresponding restoration measures. The results suggest that trends of decrease in cover and diversity of woody species were evident in the upper slopes of some stabilized dunes having less than 50% cover. The destabilized dunes with less than 20% cover are highly vulnerable to erosion. A general trend observed among dunes was that with a decrease in the cover of upper slopes, there is a decrease in the cover on lower slopes. The number of destabilized dunes is increasing without effective restoration measures against the prevailing trends of disturbances. Ranking dunes on the basis of cover could help in proposing simple restoration measures as a first step towards developing an understanding of designing adaptive strategies to restore the woody cover.

Abstract

Crop irrigation with brackish water having high Na+ is a common practice in developing countries like Pakistan; hence increasing the saline-sodic soils throughout the region. Therefore, two independent studies were conducted to evaluate the impact of minerals enriched contrasting biochars (MECBs) in mitigating Na+ toxicity on soil physicochemical properties, wheat growth, and physiology. In 1st trial, an incubation experiment was conducted having 32 treatments including simple biochar (SBc), manganese enriched biochar (MnBc), zinc enriched biochar (ZnBc), and iron enriched biochar (FeBc) applied at two rates (0.1% and 0.5%) with four different salinity levels such as 10, 20, 30, and 40 dSm−1. The soil was sampled after the 8th, 16th, and 24th day of incubation. Among the four sources of biochar, MnBc (0.1%) + 40 dSm−1 and FeBc (0.5%) + 40 dSm−1 showed efficient results to tolerate salinity stress in soil by efficiently reducing the availability of Na+ (60% and 30%) when compared to SBc (0.5%) + 40 dSm−1. Then, a pot study was conducted with 20 different treatments (control, SBc, MnBc, ZnBc, and FeBc) at four different salinity levels, i.e., 0, 5, 10, and 15 dSm−1. There were four replicates and the crop was harvested after 60 days of germination. The application of brackish water (control+15 dSm−1) significantly reduced the fresh weight of root (28%) and shoot (34%) of wheat (Triticum aestivum L.) as compared to FeBc+15 dSm−1. However, the soil Na+ toxicity was significantly decreased (23%) by the application of FeBc+15 dSm−1 as compared to control+15 dSm−1. Similarly, a significant increase was observed in leaf chl. a, b and photosynthetic rate (75%, 3 and 2-folds); however, a significant decrease was observed in transpiration rate (50%) in T. aestivum L. treated with FeBc+15 dSm−1 as compared to control+15 dSm−1. Interestingly, FeBc+15 dSm−1 also played a vital role to prevent oxidative damage by controlling the shoot CMP (63%) in T. aestivum L. by efficiently triggering the activities of shoot antioxidant enzymes such as APX (30%) and CAT (52%) when compared to control+15 dSm−1. In summary, it was evaluated that FeBc showed the highest adsorption capacity of Na+ ions to regulate salinity stress by improving soil health and crop physiology.

Abstract

The rice leaf folder, Marasmia exigua (Butler), is dangerous pests and negatively affecting the rice production worldwide. Protein elicitors are considered to be bio-factors that induce rice resistance against herbivores. The present study was performed with two protein elicitors, Hrip 1 (extracted from Alternaria tenuissima) and PebB1 (from Beauveria bassiana) to study their efficacy against the rice leaf folder. Three different concentrations of Hrip 1 (68.88, 46.69 and 28.44 µg/ml) and PebB1 (56.66, 39.76 and 32.62 µg/ml) were assigned to evaluate the developmental time, survival rate, and fecundity of M. exigua. Both elicitors were applied to the three-leaf stage of the rice plant where newly emerged adult insects were released. Bioassay results showed that after the application of protein elicitors, the life cycle and survival rate of the rice leaf folder were prolonged, while fecundity decreased. The concentration of protein had a significant (p

Abstract

Despite an increased number of studies on carbon stock estimates from tropical and temperate forests, little information is available for subtropical forests, although they constitute a significant proportion of global forest cover. In this present study, we aimed to assess the above- and below ground biomass allocation strategies and carbon stocks of Acacia modesta and Olea ferruginea, which co-dominate a subtropical dry forest in Pakistan covering approximately 1.6 Mha. This scrub forest has been subjected to mining, overgrazing, and other anthropogenic activities resulting in the loss of trees and habitat degradation. For the assessment of biomass and carbon stock, 11 trees of each species representing the diameter range of 10–52 cm at 1.3 m height were harvested. The harvested A. modesta and O. ferruginea trees showed 80% and 82% of biomass in the above-ground parts and 20% and 18% to below ground parts respectively. We developed power models from the destructive harvest data for both the above- and below-ground biomass components to assess the tree-level carbon. Furthermore, we also estimated the carbon content in the leaves, roots, and shoots of both species by using a carbon analyzer, which ranged from 43.42% to 46.50%. Using the developed models, we found that the total carbon stock was 49.82 t ha−1 in the studied forest with a basal area of 27 m2 ha−1, consisting of 568 trees ha−1. This study provides useful information about the tissue carbon content, on-site models for estimating the above- and below ground biomass and carbon stock in two dominant species from a subtropical dry forest, which can be applied to estimate the carbon stock of forests in arid climate.

Abstract

Limestone quarrying is an active mining practices generating bulk of solid remains and altering the habitat by the removal of plants; however, the utilization of such waste for the growth of plants has not been investigated much. The present study aimed to evaluate the effects of limestone quarry waste on the growth of two native plants by analyzing its physicochemical properties and utility for plantation purposes, while determining whether mitigation measures would be required for the habitat restoration of quarry site. Two species, Acacia modesta and Adhatoda vasica were selected from the quarry site habitat. These plants were grown in different proportions of quarry waste, and garden soil was used as a control. Growth was assessed by recording plant height, number of branches per plant, root and shoot length, and total biomass. We also analyzed the N, P, K, Na, Ca, and Mg contents of the root and shoot tissues of both species. We found a significant increase in plant height (1.24- and 1.19-fold greater than controls for A. modesta and A. vasica, respectively). Differences in the number branches, root, shoot length, and biomass were also found. A significant and positive relationship was found between the mineral content in roots and the total plant biomass across both species. We conclude that (1) the mining solid waste contained the necessary minerals for the studied plant species and no amelioration would be required for restoration of such sites with the selected indigenous plants; and (2) the quarry waste promoted the growth of the two selected species. The results of the present study can be used to plan habitat restoration in limestone mining areas that have lost plant cover.

Abstract

Aim of Study: The complex community of riparian reserve forest has become of great concern for researchers to develop more viable management strategies. The paper aimed to evaluate the current structural diversity of vegetation and its association with the physical environment of low-lying forest for proposing the rehabilitation interventions. Area of Study: We studied two forests, Chung-Mohlanwal and Dhana-Bheni on both riverbanks along river Ravi in the Jhok riparian reserve forest situated in the southwest of Lahore, Pakistan. Material and Methods: A methodological framework was developed based firstly, on direct comparison of diversity (measured by Hill numbers) and structure of existed vegetation layers (trees, shrubs, herbs, and grasses) and environmental factors (canopy structure, anthropogenic activities, microclimate, and soil characteristics) between the two forests and secondly, on environment-vegetation association using Canonical Correspondence Analysis (CCA) ordination method. Results: Dhana forest was more diverse vegetation layers (Shannon Diversity index 1D < 11) and intact due to plantation of uneven-aged tree stands of varied stand basal area and stem density. Microclimate under this forest could not support the dominant understory positively unlike the monoculture forest. On the contrary, Chung-Mohlanwal forest was under the influence of uncontrolled grazing activities, fuelwood extraction, and invasive species. Multivariate analysis CCA elucidated that most variance was shown by soil characteristics (38.5 %) for understory vegetation in both forests. Research Highlights: Overstory stand structure, species composition, distance to nearby communities, and soil characteristics should be considered for developing forest planting and management strategies.

Abstract

Objective: Gestational diabetes mellitus (GDM) is a growing public health concern that has not been extensively studied. Numerous studies have indicated that a variant (rs8050136) of the fat mass-associated gene, FTO, is associated with both GDM and Type 2 diabetes mellitus(T2DM). We conducted a meta-analysis on the association between the FTO single nucleotide polymorphism (SNP) rs8050136 and T2DM, followed by a case-control study on the association of the said SNP and GDM in a sample of Bangladeshi women. Method: A total of 25 studies were selected after exploring various databases and search engines, which were assessed using the Newcastle-Ottawa Scale (NOS). The MetaGenyo web tool was used to conduct this meta-analysis. A case-control study was performed on 218 GDM patients and 284 controls to observe any association between FTO rs8050136 and GDM. Genotyping was performed using the tetra-primer amplification refractory mutation system-polymerase chain reaction (T-ARMS) method, and statistical analyses were performed using various statistical softwares. Results: In the meta-analysis 26231 cases and 43839 controls were examined. Pooled association analyses revealed a statistically significant relationship between the FTO rs8050136 polymorphism and an elevated risk of T2DM under all genetic models (P<0.05). In the case-control study, synergistic analyses of the SNP and gravida with GDM revealed a significant (P<0.01) association with an increase in odds by 1.6 to 2.4 folds in multigravida and decrease in odds by 2 folds in primigravida. A positive family history of diabetes and the minor allele of this SNP collectively increased the risk of developing GDM by many-fold (1.8 to 2.7 folds). However, after accounting for family history of diabetes and gravidity, analyses showed no significant association with GDM. Conclusion: Our meta-analysis revealed a significant association between SNP rs8050136 of FTO with T2DM, and this variant was substantially associated with an increased risk of GDM in a sample of Bangladeshi multigravida women.

Author

Romshoo, S., Khan, T., Amin, U., Gowhar, R., and Mustafa, B.

Abstract

The study attempts to gain a better understanding of glacier dynamics of ~5600 glaciers covering ~17950Km2 in the Karakoram.Based on 20-year glacier area change (-0.96%) using Landsat data (2000-2020, it was shown that the glaciers are either retreating (3621), stable (1766), or even advancing (215), indicating an average recession of -4.64%, -.08% and 1.17% respectively with variation between east and west Karakoram. The analysis showed a significant influence of topography on the observed glacier changes indicated by higher altitudes and northerly aspects of the Advancing and Stable glaciers' and lower altitudes and southerly aspects of the Retreating glaciers.Due to data limitations, ice thickness changes of only a subset of the glaciers (375) were estimated using ICESat-2 altimetry (2021–2022) and SRTM DEM (2000) data.With an average thinning of -0.12 ± 0.33 ma-1, there is less thinning in the western Karakoram (-0.09 ma-1) than the eastern Karakoram (-0.16 ma-1). The thickness of the advancing glaciers increased somewhat (0.06 ma-1), the stable glaciers decreased little (-0.03 ma-1) and the retreating glaciers decreased significantly (-0.32 ma-1).The GlabTop model, based on SRTM and TanDEMx DEMs, glacier outlines and flowlines of 375 glaciers, was used to predict volume changes during 2000-2012.The model showed an overall loss of 27.0±8.9 Gt with the Advancing, Stable and Retreating glaciers losing -1.65±0.54Gt, -19.28±6.36Gt and -6.08±2.0Gt of mass respectively. Furthermore, despite advance many of the Advancing glaciers showed significant thinning (-0.7 ma-1) and considerable mass loss during 2000-2012 indicating an anomaly which is under further investigation., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)

Abstract

Third-dose coronavirus disease 2019 vaccines are being deployed widely but their efficacy has not been assessed adequately in vulnerable older people who exhibit suboptimal responses after primary vaccination series. This observational study, which was carried out by the VIVALDI study based in England, looked at spike-specific immune responses in 341 staff and residents in long-term care facilities who received an mRNA vaccine following dual primary series vaccination with BNT162b2 or ChAdOx1. Third-dose vaccination strongly increased antibody responses with preferential relative enhancement in older people and was required to elicit neutralization of Omicron. Cellular immune responses were also enhanced with strong cross-reactive recognition of Omicron. However, antibody titers fell 21–78% within 100 d after vaccine and 27% of participants developed a breakthrough Omicron infection. These findings reveal strong immunogenicity of a third vaccine in one of the most vulnerable population groups and endorse an approach for widespread delivery across this population. Ongoing assessment will be required to determine the stability of immune protection.

Author

Abstract

Emerging smart grid technologies and increased penetration of renewable energy sources (RESs) direct the power sector to focus on RESs as an alternative to meet both baseload and peak load demands in a cost-efficient way. A key issue in such schemes is the design and analysis of energy trading techniques involving complex interactions between an aggregator and multiple electricity suppliers (ESs) with RESs fulfilling a certain demand. This is challenging because ESs can be of various categories, such as small/medium/large scale, and they are self-interested and generally have different preferences toward trading based on their types and constraints. This article introduces a new contract theoretic framework to tackle this challenge by designing optimal contracts for ESs. To this end, a dynamic pricing scheme is developed such that the aggregator can utilize to incentivize the ESs to contribute to both baseload and peak load demands according to their categories. An algorithm is proposed that can be implemented in a distributed manner by trading partners to enable energy trading. It is shown that the trading strategy under a baseload scenario is feasible, and the aggregator only needs to consider the per unit generation cost of ESs to decide on its strategy. The trading strategy for a peak load scenario, however, is complex and requires consideration of different factors, such as variations in the wholesale price and its effect on the selling price of ESs, and the uncertainty of energy generation from RESs. Simulation results demonstrate the effectiveness of the proposed scheme for energy trading in the local electricity market.

42. Identification of Composite Insulator Criticality based on a new Leakage Current Diagnostic Index

Author

Abstract

In this article, a new method is proposed to identify the health condition of composite insulators through investigating the leakage current (LC) along with the electric potential (EP) and electric field stress (EFS) profiles. In this regard, variations of the LC harmonics and the distribution profiles of the EP and EFS are investigated through a series of experimental and simulation analyses conducted on composite insulators under various environmental and pollution conditions. Fast Fourier transform (FFT) and a COMSOL-multiphysics environment are utilized to analyze this variation. The results reveal a strong correlation between the LC harmonics and the insulator health condition. A new diagnostic criticality index based on the third to the fifth harmonic ratios of the insulator LC is proposed to quantify the composite insulator criticality and predict the likelihood of flashover occurrence. The EP and EFS analyses can be used to provide a complementary diagnosis of the insulator’s health state under severe pollution and humidity conditions. The proposed analysis enables the transmission line network operator to get an insight into the insulators’ functional status, thus improving the network reliability through avoiding insulator failure and adopting a proper condition-based maintenance scheme.

Abstract

Fungi are a large group of eukaryotes found as saprophytes, pathogens or endophytes, which distribute in every corner of our planet. As the main pathogens, fungi can cause 70–80% of total plant diseases, leading to huge crop yield reduction and economic loss. For identification of fungal plant pathogens, mycologists and plant pathologists have mainly gone through two stages, viz. morphological observation and morphology/phylogeny, and the next era might be utilizing DNA barcodes as the tool for rapid identification. This chapter accounts i) the brief history of development for fungal identification tools and main concepts, ii) the importance and confusion of “One fungus, one name” for pathogen identification, iii) more or fewer species that we need in agricultural practice, and iv) the foreground of fungal plant pathogen identification. These will help to solve the practical problems of identification of fungal pathogens in agricultural production.

Abstract

A search for pair production of the supersymmetric partner of the top quark, the top squark, in proton-proton collision events at s = 13 TeV is presented in a final state containing hadronically decaying tau leptons and large missing transverse momentum. This final state is highly sensitive to high-tan beta or higgsino-like scenarios in which decays of electroweak gauginos to tau leptons are dominant. The search uses a data set corresponding to an integrated luminosity of 77.2 fb(-1), which was recorded with the CMS detector during 2016 and 2017. No significant excess is observed with respect to the background prediction. Exclusion limits at 95% confidence level are presented in the top squark and lightest neutralino mass plane within the framework of simplified models, in which top squark masses up to 1100 GeV are excluded for a nearly massless neutralino.

Abstract

Optimizing the scheduling of heating, ventilation, and air-conditioning (HVAC) systems in multizone buildings is a challenging task, as occupants in various zones have different thermal preferences dependent on time-varying indoor and outdoor environmental conditions and price signals. Price-based demand response (PBDR) is a powerful technique that can be used to handle the aggregated peak demand, energy consumption, and cost by controlling HVAC thermostat settings based on time-varying price signals. This paper proposes an intelligent and new PBDR control strategy for multizone office buildings fed from renewable energy sources (RESs) and/or utility grid to optimize the HVAC operation considering the varying thermal preferences of occupants in various zones as a response of real-time pricing (RTP) signals. A detailed mathematical model of a commercial building is presented to evaluate the thermal response of a multizone office building to the operation of an HVAC system. The developed thermal model considers all architectural and geographical effects to provide an accurate calculation of the HVAC load demand for analyses. Further, Occupants’ varying thermal preferences represented as a coefficient of a bidding price (chosen by the occupants) in response to price signals are modeled using an artificial neural network (ANN) and integrated into the optimal HVAC scheduling. Furthermore, a control mechanism is developed to determine the varying HVAC thermostat settings in various zones based on the ANN prediction model results. The effect of the proposed strategy on aggregator utility with wider implementation of the developed mechanism is also considered. The optimization problem for the proposed PBDR control strategy is formulated using a building's thermal model and an occupant's thermal preferences model, and simulation results are obtained using MATLAB/Simulink tool. The results indicate that the proposed strategy with realistic parameter settings shows a reduction
