Integrated Approach to Hydrogeochemical Appraisal and Quality Assessment of Groundwater from Sargodha District, Pakistan

Hydrochemical characteristics and aquifer properties present a better understanding of the mitigation of groundwater pollution, which has become one of the leading environmental concerns and threats to the sustainable ecosystem. Seventy-seven groundwater samples were collected from Sargodha District (Pakistan) and characterized for their physical and chemical properties. The analytical data were processed for the evaluation of the processes that control the groundwater chemistry using various drinking and agricultural indices with statistical and hydrochemical modeling. The predominant hydrochemical type was found to be Ca-HCO3 type, followed by Na-HCO3 and Mg-Ca-Cl types. The present study showed that the main factors controlling the groundwater chemistry were the prevalent rock dominance alongside the weathering of silicates, solubilization of carbonates, and cation exchange processes. Entropy water quality index (EWQI) revealed that 6.51% represented “poor water,” while 7.79% were considered “extremely poor” for drinking purposes. However, USSL classification, Wilcox diagram, and other agricultural indices (RCS, SAR, %Na, MH, PI, and PS) showed that the majority of the samples were classified as suitable for irrigation purpose. However, 16% of the samples for %Na and 24% of the samples for MH were not suitable for agricultural purposes. Overall, the groundwater quality was affected by the anthropogenic stress in the study area.
The Effects of Socio-Cultural Context on Breach of Accounting ethics: A Grounded Theory Study

This study explores intuitions of accounting education key stakeholders in Khyber Pakhtunkhwa, Pakistan that what are the effects of social and cultural factors on ethical breaches of accountants and tax evasion. Individual and organizational decisions are based on accounting yet, social and cultural obligations coerce accountants on manipulation of accounts for tax evasion that has negative impact of national exchequer. This study attempts to realize insights of important stakeholders about AE through methodical support of its multifaceted angles. Literature highlights that personal, organizational (multi)national decisions are based on accounting information. Stakeholders’ theory lens is applied as it is widely used in accounting research. Researchers have applied qualitative research approach to provoke 25 open-ended interviews of respondents like, accounting teachers, students, professionals, employers, recruiting agencies and their parents. Data are analyzed through constructivist grounded theory. Findings show that excessive social demands compel accountants on unethical accounting practices for tax evasion that is detrimental for the nation as it makes corruption acceptability in society. In context of the study, weak academic and HR policies lead to appointment of less relevant persons for leading accounting seats. Recommendations of the study are societal interventions, academic endorsements, regulatory and legislative suggestions for eradication of ethical breaches by accountants generally and tax avoidance specifically.
Relative Weights of Physical Strength Factors in Sports Events: Focused on Similarity Sports Events Group According to the Sports Physiological View

The purpose of this study was to investigate the relative weights of physical strength factors in sports events. We selected 16,645 people as a sample group who participated in physical fitness measurements through eight sports science centers across the country from 2016 until August of 2018, and divided into four sports types depending on the sports physiological view: type A: short-term muscular power and short-term muscular endurance, type B: mid-term muscular power, type C: long-term cardiorespiratory endurance, type D: coordination capability (CC), agility, flexibility, and balance. Categorized the performance level into excellent athletes and non-excellent athletes, and standardized (T-score) the measured value after considering sex, age and sports type group. Used logistic regression analysis for the method of analysis, and calculated the relative weights of physical strength factor with different sports by using Wald value which was calculated from logistic regression analysis. As a result, the relative weights of physical factor in type A were power 30%, muscular power (MP) 18%, CC 16%, agility 11%, flexibility 10%, cardiorespiratory endurance (CE) 1%, and balance 0%. The relative weights of physical factor in type B were muscular endurance (ME) 43%, MP 25%, power 20%, balance 9%, CE 2%, flexibility 1%, agility 0%, and CC 0%. The relative weights of physical factor in type C were ME 41%, CE 37%, power 10%, agility 8%, flexibility 2%, CC 2%, ME 0%, and balance 0%. Need more specific classification standard for type D sports. Hope the results of this study were used to measure physical fitness level and used as baseline data for recruiting future talents.
Long Range UAS Mission by LPWAN Communication

One of the key challenges for long range Unmanned Aerial Systems (UAS) is the limitation of the communication capability. Many existing communication technics are conventionally adopted in UAS to improve the quality of the communication such as satellite communication, cellular networks, and relay aircrafts. However, the mentioned solutions often incur several drawbacks including costs, complexity, communication delay, or inefficient power consumption. LoRaWAN is one of the recently emerging communication technics used in the Low Power Wide Area Networks (LPWAN) technology. It has a promising potential to improve the coverage of UAS communication, since it can transmit/receive signals below the noise floor in a very long range with very low energy consumption by using the waveform modulation technique called Chirp Spread Spectrum (CSS). In this paper, we show the potential of LPWAN as the supplementary communication in UAS. The experiment results show that LoRaWAN can maintain the communication capability beyond 80 km where the popular RF device, RFD900x, has lost its ability to communicate at this distance.
C2C co-creation of inclusive tourism experiences for customers with disability in a shared heritage context experience

ABSTRACT This study explores customer-to-customer (C2C) social co-creation practices in tourism when customers with and without disability share a heritage service environment. Despite a growing prevalence of heritage- and disability-related research in the tourism literature, few scholars have examined the phenomena from the emergent customer-dominant logic (CDL) perspective. This study makes empirical use of the perceptions of customers with disabilities (CwD) in a recent process of co-creation of CDL within the context of heritage sites through qualitative ethnographic techniques, interviews and observation methods. A sample of 125 individuals with and without disabilities participated in the fieldwork. The objective was to identify C2C social practices that occur among CwD and their related value, leading to either inclusion or exclusion. The results reveal the importance of focusing on C2C co-creation opportunities which create a value outcome. This paper provides heritage managers with clear guidance for creating inclusive and enabling servicescapes.
SAMA: a real-time Web search architecture

ABSTRACT With the increasing number of information resources in the World Wide Web, how to retrieve real-time information is becoming very important. The resources include traditional databases, flat files, knowledge bases, topical content and programs. In this paper, we propose a new model for retrieving high-quality data from distributed Web resources over the Internet. Unlike traditional models which are web crawler-based algorithms and collect data prior to indexing, supposedly making the process going offline, the proposed algorithm embeds the crawling process with the searching process to make the process more realistic since data are collected and indexed in real-time fashion. We aim to get high-quality and refreshed results for every user’s query, as well as, for better query expansion and formulation. In our experiments, we found that the proposed approach was highly relevant for most recently searched queries, consisting in its performance and resilient to the drawbacks faced by other techniques.
Teaching Environmental Sustainability while Transforming Study Abroad

Environmental issues are of especially great importance to younger individuals, such as university students. Course-based Undergraduate Research Experiences (CUREs) are a proven methodology for transforming short-term study abroad to yield higher impact and quality student outcomes, especially as they relate to teaching environmental sustainability. This paper offers a review of tested pedagogical frameworks, provides evidence to substantiate this statement from assessment data, and offers insights on how to develop and implement an international CURE. It also shares how embedding CUREs into innovative and high-quality short-term study abroad experiences can work to positively transform the post COVID-19 era of short-term study abroad. Several case studies are presented that document how students’ hands-on involvement in developing questions about real-world sustainability issues, devising and carrying out group research, and presenting their findings affect their acquisition of scientific skills and a sustainability-oriented mindset.

Effect of melt and solution electrospinning on the formation and structure of poly(vinylidene fluoride) fibres

We investigated the effects of applied voltage and collector rotating speed on the crystal structure and piezoelectricity of poly(vinylidene fluoride) (PVDF) fibres obtained by two electrospinning (ES) systems; laser-melt electrospinning (M-ES) and conventional solution electrospinning (S-ES). A higher β phase fraction was observed in the S-ES fibres, although the M-ES fibres showed comparable crystallinity. The piezoelectric constant (d33) for the S-ES fibres was also higher than that of the M-ES fibres. This is the first report clarifying the difference between M-ES and S-ES for the formation of PVDF fibres.
Experimental constraints on volcanic ash generation and clast morphometrics in pyroclastic density currents and granular flows

<p>Pyroclastic density currents (PDCs) present perhaps the greatest proximal primary hazard of volcanic activity and produce abundant fine ash that can present a range of health, environment and infrastructure hazards. However, direct, fully quantitative observation of ash production in PDCs is lacking, and little direct evidence exists to constrain the parameters controlling ash generation in PDCs. Here, we use an experimental approach to investigate the effects of starting mass, material density and ash removal on the efficiency of ash generation and concurrent clast rounding in the dense basal flow of PDCs. We employ a rotary drum to tumble pumice and scoria lapilli clasts over multiple transport &#8220;distance&#8221; steps (from 0.2 to 6&#160;km). We observe increased ash generation rates with the periodic removal of ash during the experiments and with increasing starting mass. By scaling to the bed height and clast diameter we obtain a general description for ash production in all experiments as a function of flow distance, bed height and average clast diameter. We confirm that changes in lapilli shape factors correlate with the ash fraction generated and that the grain size of ash produced decreases with distance. Finally, we estimate shear rate in our experiments and calculate the inertial number, which describes the ratio between clast-scale and flow-scale rearrangement during flow. We show that, under certain conditions, fractional ash production can be calculated accurately for any starting mass solely as a function of the inertial number and the flow distance. This work sheds light on some of the first systematic and generalizable experimental parameterizations of ash production and associated clast evolution in PDCs and should advance our ability to understand flow mobility and associated hazards. </p>

Assessment of some heavy metals in various aquatic plants of Al-Hawizeh Marsh, southern of Iraq

Abstract. Al-Abbawy DAH, Al-Thahaibawi BMH, Al-Mayaly IKA, Younis KH. 2021. Assessment of some heavy metals in various aquatic plants of Al-Hawizeh Marsh, southern of Iraq. Biodiversitas 22: 338-345. In order to describe the degree of contamination of aquatic environments in Iraq, heavy metals analysis (Fe, Ni, Cr, Cd, Pb, and Zn) was conducted for six aquatic macrophytes from different locations of Al-Hawizeh Marsh in southern Iraq. The six species were Azolla filiculoides (floating plant), Ceratophyllum demersum, Potamogeton pectinatus, Najas marina (submerged plants), Phragmites australis, and Typha domingensis (emergent plants). The results indicate that cadmium, chromium, and iron concentrations in aquatic plants were above the World Health Organization (WHO). In contrast, zinc, copper, and lead were within the allowable limits. C. demersum and N. marina showed higher concentrations of heavy metal accumulation than the other aquatic plants. The concentration of heavy metals in plant tissues during the summer months was higher than in the different seasons. C. demersum and N. marina showed higher concentrations of heavy metal accumulation than the other aquatic plants. Heavy metal bioconcentration (BCF) was calculated to assess heavy metals bioaccumulation in the aquatic plants.
Gas Kinetics, Ruminal Characteristics, Hydrogen Cyanide Content, and In Vitro Degradability: Effect of Elemental Sulfur, Fresh Cassava Root, and Urea

The study aimed to elucidate the optimum level of elemental sulfur, fresh cassava root (FCR), and urea and their effect on gas production, ruminal fermentation, thiocyanate concentration, and in vitro degradability. A 3×2×4 in a completely randomized design were conducted. Factor A was level of sulfur at 0%, 1%, and 2% of concentrate dry matter (DM), factor B was level of urea at 2% and 4% of concentrate DM, and factor C was level of the FCR at 0, 200, 300, and 400 mg of the total substrate. The study found that elemental sulfur, urea, and FCR had no interaction effect on the kinetics of gas, ruminal fermentation, hydrogen cyanide (HCN), and in vitro degradability. Elemental sulfur supplementation (P<0.05) significantly increased the gas produced from an insoluble fraction (b), in vitro DM degradability and either neutral detergent fiber or acid detergent fiber degradability, and propionate (C3) concentration while decreased the ruminal HCN concentration. Urea levels showed a (P<0.05) significant increase of the potential extent of gas production, ruminal NH3-N, and total volatile fatty acid (VFA). FCR supplementation (P<0.05) significantly increased the gas produced from an immediate soluble fraction (a), gas produced from insoluble fraction, gas production rate constant, total VFA, C3 concentration, and HCN while decreased ruminal pH, acetate, and butyrate concentration. It could be concluded that 2% elemental sulfur, 4% urea, and 300 mg FCR showed a greater effect on gas production, ruminal fermentation, and HCN reduction.
Synthesis of vanadium dioxide thin films and nanostructures

Vanadium oxides (VxOy) are classic “smart functional materials” used in a wide array of thermochromic, electronic, and catalytic applications. Specifically, vanadium dioxide (VO2) class nanomaterials are of enormous interest due to their unique first order reversible metal-insulator phase transition (MIT) behavior accompanied by a structural phase transition, inducing dramatic changes in electrical and optical properties with large lattice deformation. To date, a plethora of reports exemplifying the MIT characteristics of VO2, synthetic methods of VO2, and modulating VO2 phase transition temperatures (Tc) have been published. In this Tutorial Review, we present an overview on the fundamentals of the VO2 band structure and principles of MIT and outline various reported synthetic approaches for VO2 thin films, including dimensionally oriented VO2 nanostructures. Discussion on recent trends in VO2 applications, challenges in VO2 synthesis, and future perspectives are also elaborated in detail.
Food waste solution at home: conventional and rapid composting techniques

Food waste is a significant concern in waste management in recent years due to the inevitable outcome of human consumption in modern society. It has happened in almost every home daily. In Malaysia, 44.5% of organic waste (OW) consists of food waste (FW), this figure would increase with population growth. Therefore, without effective FW management, untreated FW dumping will cause environmental pollution, thus affecting human health as well as ecosystems. Conventional methods such as landfill and incineration have long been the most popular practice to address the FW issues, offering simple and cost-effective approach. Most of the time, these methods are not sustainable since they pose other environmental pollution such as greenhouse gas (GHG) emissions and leachate contamination leading to groundwater pollutions. Other issues with landfills are that self-composting at landfill site takes a long time and most landfills in Malaysia are almost at full capacity. The composting technique has recently gained more attraction as a cost-effective and sustainable method for the FW issue. This paper reviews techniques of composting food waste at home by using a conventional natural and rapid process. The performance of each technique in terms of cost, sustainability, user-friendly and time are measured in this review. Finally, the future direction of food waste solution by sustainable composting technique is briefly discussed in this paper.
Electrospray ionization mass spectrometric study of calcium binding to calmodulin in the presence of magnesium and terbium

Ca 2+ , Mg 2+ and Tb 3+ binding on calmodulin (CaM) was studied using electrospray ionization mass spectrometry. The solvent used was ammonium acetate (5 mM, pH 6.0). The calcium and magnesium stoichiometries were the same as previously described in the presence of 20% methanol. The study of competition between Ca 2+ and Mg 2+ showed that magnesium binds on auxiliary cationic sites. It was also found that six Tb 3+ , the most frequently used probe for the determination of calcium binding sequence on CaM, bind to this protein in addition to four Ca 2+ . This result clearly confirms the existence of a maximum of ten cationic sites on CaM
Usefulness of Bioelectrical Impedance Analysis as a Guidance of Fluid Management in Critically Ill Patients after Major Abdomen Surgery; a Single Center, Prospective Cohort Study

Purpose: We evaluated the patterns and changes in bioelectrical impedance analysis parameters of patient who underwent abdominal surgery throughout the early period in surgical intensive care unit stay. Materials and Methods: From May 2019 to April 2020, patients admitted to surgical intensive care unit for more than 48 hours after surgery were enrolled. Body composition and volume status of patients were measured prospectively using portable bioelectrical impedance analysis device every morning for three days from the day of intensive care unit admission. Overhydration was defined as the case where the value of extracellular water ratio is above 0.390, and the participants were daily classified into overhydration or normohydration group. Relationship between daily volume status measured by bioelectrical impedance analysis and outcomes was assessed. Results: 107 patients who underwent abdominal surgery and 26 patients who underwent endovascular surgery were reviewed as control group. During the first postoperative 48 hours, most of them showed overhydration status, while the rate of overhydaration was significantly lower in the control group. Overhydration status on day 3 was significant predictors of postoperative morbidities (OR 5.709, 95% CI 2.199~14.819, P<0.001) and in-hospital mortality (OR 4.244, 95% CI 1.398~12.883, P<0.001). Conclusion: Overhydration status by extracellular water ratio on postoperative day 3 needs careful monitoring and appropriate interventions to improve the postoperative morbidities and in-hospital mortality. Bioelectrical impedance analysis could be a simple, easy and useful tool to monitor the volume status of patients who requiring intensive fluid resuscitation after abdominal surgery.
