User Acceptance of Enterprise Resource Planning (ERP) Systems in Higher Education Institutions: A Conceptual Model

It has become common practice for higher education institutions (HEIs) to replace existing computer systems, called legacy administrative information systems, with new ones to cope with the continuously changing demands in the context of education. At the top of these systems is enterprise resource planning (ERP) systems that integrate HEIs' business processes, functions, and data to improve their overall productivity and effectiveness. However, many studies on ERP adoption have shown that organizations frequently face several barriers, and the failure rate is high. In addition, various research projects have concluded that, quite often, HEIs do not obtain the expected advantages from the adoption of the ERP system. This research aims to explore the factors that affect the behavioral adoption and acceptance of an ERP system in the context of HEIs. Based on works from literature and authors' observations of the PeopleSoft system (ERP system) implementation at Yanbu University College (YUC) in Yanbu City, Saudi Arabia (SA), a conceptual model of users' acceptance of ERP systems has been proposed. The framework is based on the unified theory of acceptance and use of technology (UTAUT) model and is extended with additional constructs. The present study offers a theoretical contribution by extending the UTAUT model to provide a richer understanding of users' adoption behavior of ERP systems in the HEI context. In addition, according to the authors' knowledge, this is the first paper that to address ERP users' adoption perspective in HEIs in SA.
Analysis of Water Sorption Isotherms of Superabsorbent Polymers by Solution Thermodynamics

Water sorption isotherms of superabsorbent polymers were measured, and their affinity for water was evaluated by solution thermodynamics. The results provide basic data for the functional packaging of food to control the water content of food during its transportation or storage. Water activity above 0.9 was measured by adding a specific amount of water to the samples, while that below 0.9 was measured with apparatus for evaluating water sorption isotherms. Thus, water sorption isotherms for superabsorbent polymers were obtained up to a water activity of approximately 0.98. The amount of water sorbed by the superabsorbent polymers was influenced by the type of functional groups in the polymers, and not by the degree of cross-linking in the polymers. The integral Gibbs free energy, which is the most suitable parameter for evaluating the affinity of a material for water, was evaluated from the water sorption isotherms by using solution thermodynamics.
Improving CHN measurements in carbonate‐rich marine sediments

CHN elemental analysis is a common and effective method for determining total carbon (TC), total organic carbon (TOC), inorganic carbon (IC) by difference, and total nitrogen (TN) in marine sediments. In this article, we identify and describe three problems related to CHN measurement in carbonate‐rich (>30% CaCO3) marine sediments and suggest mitigation methods to obtain the most accurate measurements of TC, TOC, IC, and TN. These problems involve (1) sample size limitations, (2) incomplete carbonate digestion during in‐situ acid addition, and (3) nitrogen contamination during acid additions. Carbonate‐rich marine sediments often have low TOC and TN content and are susceptible to incomplete combustion, due to their high IC (CaCO3) content, and require careful sample size selection to optimize analysis. Incomplete digestion of carbonate prior to TOC analysis can introduce significant error into the measurement, and here we propose a testing methodology to ensure effective carbonate digestion. Atmospheric contamination of sulfurous acid, used for carbonate digestion, is also observed and modeled, and we suggest steps to minimize this contamination. Overall, our results allow for the development of sediment‐specific protocols for accurate CHN measurements in carbonate‐rich marine sediments.
Hot Carrier Stress Sensing Bulk Current for 28 nm Stacked High-k nMOSFETs

This work primarily focuses on the degradation degree of bulk current (IB) for 28 nm stacked high-k (HK) n-channel metal–oxide–semiconductor field-effect transistors (MOSFETs), sensed and stressed with the channel-hot-carrier test and the drain-avalanche-hot-carrier test, and uses a lifetime model to extract the lifetime of the tested devices. The results show that when IB reaches its maximum, the ratio of VGS/VDS values at this point, in the meanwhile, gradually increases in the tested devices from the long-channel to the short ones, not just located at one-third to one half. The possible ratiocination is due to the ON-current (IDS), in which the short-channel devices provide larger IDS impacting the drain junction and generating more hole carriers at the surface channel near the drain site. In addition, the decrease in IB after hot-carrier stress is not only the increment in threshold voltage VT inducing the decrease in IDS, but also the increment in the recombination rate due to the mechanism of diffusion current. Ultimately, the device lifetime uses Berkley’s model to extract the slope parameter m of the lifetime model. Previous studies have reported m-values ranging from 2.9 to 3.3, but in this case, approximately 1.1. This possibly means that the critical energy of the generated interface state becomes smaller, as is the barrier height of the HK dielectric to the conventional silicon dioxide as the gate oxide.
Divergent impacts of land use/cover change on summer precipitation in eastern China from 1980 to 2000

We conducted three pairs of 21‐year (1980–2000) experiments using the Weather Research and Forecast (WRF) model. The paired two experiment members were identical, except for the underlying land use/cover data, which were from the early 1980s and 2000 (hereafter, EXP1980 and EXP2000), respectivley. The differences in EXP1980 and EXP2000 were primarily induced by the land use/cover change (LUCC) from the early 1980s to 2000. To minimize the effects of WRF model uncertainties, the ensemble mean of three couples was applied. We found that the modifications of LUCC on summer precipitation over eastern China exhibited inter‐annual variability rather than kept fixed through 1980 to 2000. Due to the LUCC, the precipitation in eastern China may be decreased in 1981, 1984, 1986, 1988, 1989, and 1998 (hereafter, LR years) while increased in 1983, 1985, 1993, 1994, 1995, and 1999 (hereafter, MR years). Due to large discrepancy of large‐scale circulation background between MR years and LR years, there are different modifications by the LUCC on surface energy budget and therefore also on temperature, air pressure, water vapour supply and, eventually, precipitation. In the MR years, the LUCC induced increased evapotranspiration (i.e., latent heat) and decreased sensible heat over the middle and north partitions of eastern China; hence, there was a cooling effect. This cooling effect led to a decline in surface air pressure, thereby intensifying the ocean‐land pressure gradient; as a result, ocean‐to‐land movement of water vapour increased. Eventually, this led to increased precipitation. In the LR years, the LUCC induced significantly more sensible heat and slightly more latent heat over the north partition of eastern China, resulting in a warming effect. Then, the modifications to the surface air pressure and ocean‐land pressure gradient, as well as the water vapour flux, were reversed to those of the MR years, eventually leading to decreased precipitation.
University of Birmingham Computational study of the adsorption of benzene and hydrogen on palladium–iridium nanoalloys

The preferred chemisorption sites on a variety of palladium-iridium nanoalloys are determined for benzene and hydrogen molecules. Available sites on the surface of the nanoalloys are explored using a random-search method, directly at the density functional level of theory. These searches successfully reveal the site preference for benzene and signiﬁcant nanosize e ﬀ ects in the chemisorption of hydrogen. It is hoped that through the study of the chemisorption properties of Pd-Ir nanoalloys, complex catalytic processes, such as tetralin hydroconversion and the preferential oxidation of CO, can be better understood.
Damage levels of sunburn in pineapple fruits submitted to natural and artificial protection

Pineapple sunburn (SB) occurs mostly in regions with a high incidence of sunlight and temperature, causing damage to the fruits and financial losses for the producer. The objective of this study was to evaluate natural and artificial protection in the reduction of physical and physiological damage in pineapple, submitted to high temperature and sunlight. The experimental design was in randomized blocks with seven treatments: single planting of pineapple (cv. Pérola), with and without the protection of fruits with woven fabrics (TNT) and intercropping with cassava (cv. Amazonas) in different spacing in the row (0.40; 0. 60; 0.80; 1.00; and1.20 m), and three replications. For the study, a scale of damage level (DL) to the pineapple by SB was established, ranging from 0 to 4 (DL0 - 4). Chlorophyll content, mass of fruits and crown, percentage of fruits with SB, and commercial fruits were evaluated. The TNT uses showed maximum protection for the fruits, being all suitable for fresh consumption no damage (DL0). In intercropping, the spacing of 0.80 and 1.20 m is indicated to maximize fruit production and protection. The absence of fruit protection caused damage up to N4, with fruits strictly suitable for industry (70%) and disposal (13%). In an environment with high temperature and irradiation, the adoption of fruit protection is necessary. The planning of floral induction allows the fruiting to not coincide with the critical period of high solar incidence and temperature and can avoid the use of protection strategies. The intercropping of pineapple and cassava protects pineapple fruits against sunburn; moreover, its use does not leave inorganic residues in the environment; therefore, it is strongly recommended as a strategy to reduce sunburn in pineapple fruits.
Differences in Body Fat, Body Mass Index, and Physical Performance of Specific Field Tests in 10-to-12-Year-Old School-Aged Team Handball Players

This study aimed to compare 10-to-12-year-old Qatari male athletes and assess body fat, body mass index, and physical fitness, as well as the difference of these measures between ages. Thirty-five youth handball players volunteered for the investigation and were divided into three groups: 12-year-old players (U12; n = 12), 11-year-old players (U11; n = 11), 10-year-old players (U10; n = 12). Anthropometry was assessed by body mass, body fat percentage (%BF), and body mass index (BMI). Measurements included the Yo-Yo Intermittent Recovery Test Level 1 (Yo-Yo IR1), jumping ability (squat and countermovement jumps (SJ and CMJ, respectively)), and sprint tests (10 and 15 m). The power of the upper extremity was measured by a 2-kg overhead medicine ball throw for distance. Except for %BF (p = 0.387) and BMI (p = 0.070), all anthropometric and demographic parameters were different between age groups. The largest differences were found for body mass (p = 0.007) and body height (p = 0.008). Regarding fitness parameters, only the medicine ball throw (p = 0.022) was different between age groups (U10 vs. U12: p = 0.009; U11 vs. U12: p = 0.048). There was no difference between groups for jumping (CMJ: p = 0.586; SJ: p = 0.377), sprinting (10 m: p = 0.211; 15 m: p = 0.194) and Yo-Yo IR1 (p = 0.228). Body fat was the anthropometric parameter with the strongest relationship with physical performance in that lower body fat was related to superior jumping performance and sprint performance. In conclusion, except for %BF and BMI, all anthropometric parameters were different between U10, U11, and U12 handball players. For physical parameters, jumping, sprinting, and endurance performance were not different between age groups. From a practical perspective, coaches can use these findings as reference for the evaluation of their school-aged handball players, as well as for establishing performance goals.
The European Parliament’s mandate for trilogues: explaining the discretion of political group advisors

ABSTRACT To fully grasp EU inter-institutional negotiations, we need to understand how EU institutions internally prepare for trilogues and what the involvement of staff actors is in this process. This article sets out to uncover the backstage co-ordination of the European Parliament’s (EP) mandate for trilogues and seeks to explain the discretion of political group advisors (PGAs) in these preparations. Based on interviews and a survey, it identifies the conditions reinforcing or constraining their autonomy. PGAs’ autonomy is highest during the early stages of co-ordination, ahead of group and shadows meetings. PGAs then act without clear instructions and base their actions on what they deem to be in line with the group’s political agenda. Trust is a necessary condition for their pro-active involvement in the intra-institutional negotiations, since (shadow) rapporteurs allocate work to EP staff actors only when they can rely on their loyalty. In addition, advisors’ political sensitivity and informal networks enable them to accurately represent political positions in negotiations at staff level and formulate strategies acceptable to Members of European Parliament (MEPs).
A method for increasing the bandwidth of slot and patch antennas using grid‐slotted patch

A method for expanding the bandwidth of slot and patch antennas is proposed in this article. The use of grid‐slotted patch helps to improve the impedance matching of the antenna, thus the bandwidth can be extended. The design process and an analysis of using a grid of slots to increase the bandwidth of a slot antenna is first given. The simulated S11 of the broadband slot antenna is less than −11 dB in the range of 2.6 to 3.42 GHz. To further demonstrate the method, an aperture‐coupled patch antenna with grid‐slotted patch is designed. The measured S11 of the broadband patch antenna is less than −10 dB in the range of 1.95 to 4.15 GHz and the peak gain is 9.6 dBi.
In vitro cytotoxic effect of Aspergillus clavatus generated silver nanoparticles on RAW 264.7 cells

Aspergillus clavatus (A. clavatus ) was utilized for the synthesis of silver nanoparticles (AgNPs) isolated from the soil. About one (1) mM silver nitrate (AgNO3) was gradually added to the aqueous extract of A. clavatus, the colour of the extract becomes dark brown indicates the AgNPs formation. The UV -Vis spectrophotometry showed the lambda max (-λmax) at 430 nm. Fourier-transform infrared spectroscopy (FTIR) results revealed the peaks at 3221.40 cm N-H symmetric amide, 1645.78 NH bend amine, 1557.02 N-H bend amide groups are associated with AgNPs. The powder form of AgNPs was recorded for X-ray diffraction (XRD) confirms the crystalline nature of AgNPs. Energy dispersive X-rays (EDX) showed the presence of silver, while zeta potential ( ζ-potential) -65mV value confirms AgNPs are stable. Transmission electron microscopy (TEM) revealed AgNPs size ranges from 23.65 to 36.99 nm and is spherical in shape, showing no agglomeration. For cytotoxic effect AgNPs showed IC50 value at 125 μg/ ml against RAW cells through MTT assay.
Total electrolyte balance for laying hens

ABSTRACT: This study was done to determine the best value of the total electrolyte balance (BET) concerning the variables of performance and egg quality of the laying hens. We investigated 240 Hy-Line Brown laying hens, of 30 to 46 weeks of age, adopting the completely randomized experimental design, which included five treatments (1000, 1250, 1500, 1750 and 2000 μeq / kg), 8 repetitions and 6 birds per unit. The performance and quality of the birds’ eggs were evaluated in the different treatments. The results were subjected to the analysis of variance and, wherever significant effect was noted, the regression equations were estimated, taking into account the electrolyte balance (μeq / kg) as a concomitant variable, applying the SAS statistical program (2001). The consumption, production, and feed conversion variables by dozen eggs, final bird weight, egg density, yolk color, Haugh Unit, albumen weight, shell weight, and egg weight, were found to be unaffected by the experimental BET values. The values of the feed conversion per egg mass, yolk weight and uniformity were affected by the different BETs. The electrolyte balance values showing minimum feed conversion, higher yolk weight, and better uniformity were, respectively, BET = 1400, 1330, and 1250 in μeq / kg of loads at the different temperatures. From the regression equations, the value indicated was BET=1390 for the 30- to 46-week-old laying hens. The electrolyte balance of the diet was found to affect the laying hens in terms of performance and egg quality.
Der Schluß von Reiz-Reaktions-Funktionen auf System-Strukturen

Die experimentelle Analyse der optokinetischen Reaktionen des Rüsselkäfers Chlorophanus viridis deckte mehrere, gleichzeitig vorhandene Interaktions-Weisen benachbarter Ommatidien auf (s. Tabelle in Abschnitt V S. 523). Aus ihnen soll auf die zugrunde liegende Systemstruktur geschlossen werden, die im ZNS des Käfers verwirklicht sein muß. Zu diesem Zweck wird ein allgemeiner axiomatischer Ansatz für den Schluß von Reiz-Reaktions-Funktionen auf Systemstrukturen gegeben: I. Theoretisch fehlerfrei ist nur der Schluß auf die hinreichende und notwendige Struktur. II. In den Verrechnungselementen der Systemstruktur müssen die physikalischen Informationsträger nach demjenigen Gesetz aufeinander einwirken, welchem in dem betreffenden Verrechnungsakt die Informationswerte gehorchen. III. Unter bestimmten Bedingungen muß ein System mindestens in einem seiner Querschnitte ebenso viele isolierte Leitungen besitzen als unabhängige und verrechnete Eingangs-Informations-Daten. IV. Bei unvollkommener Isolierung von Informationsleitungen geht die Unabhängigkeit der geleiteten Informationen, welche eine Bedingung für das Zustandekommen von Verrechnungen zwischen Informationswerten ist, schneller als proportional zur Isolationsabnahme verloren.
Human Consciousness: The Role of Cerebral and Cerebellar Cortex, Vagal Afferents, and Beyond

Human Consciousness is one of most elusive issues in the scientific history. Its nature created major historical debate started thousands of years ago and still ongoing. Despite the explosive developments in the last 6 decades to explore its nature, the knowledge about it is still deficient. The important advances in the twentieth and 21st centuries in understanding cerebral cortex dynamics fortified by the dominant materialistic philosophical approach of the era dictated its impact on consciousness science, which is understood as sole human brain function. This chapter is a call for holistic perception of human consciousness incorporating the ancient wisdom of the human civilizations with the massive current advances in different disciplines of applied sciences. The description of René Descartes in the 17th century of the Cartesian dualism is timely to revisit with new holistic perspective, in view of the major advances of our understanding of heart brain communications, astrophysical resonances with, human heart and central nervous system frequencies, and signaling between humans and their large environment. Neural and psychological correlates of human consciousness which dominate the consciousness research nowadays should undergo revolutionary conceptual understanding to perceive consciousness as a massive universal event expanding from human genes to galaxies with cerebral cortex as major player.
Determination of Surface Crack Orientation Based on Thin-Skin Regime Using Triple-Coil Drive–Pickup Eddy-Current Sensor

Electromagnetic sensors have been used for inspecting small surface defects of metals. Based on the eddy-current (EC) thin-skin regime, a revised algorithm is proposed for a triple-coil drive–pickup EC sensor scanning over long surface crack slots (10 mm) with different rotary angles. The method is validated by the voltage measurement of the designed EC sensor scanning over a benchmark (ferromagnetic) steel with surface defects of different depths and rotary angles. With an additional sensing coil for the designed EC sensor, the defect angle (or orientation) can be measured without spatially and coaxially rotating the excitation coil. By referring to the voltage change (due to the defect) diagram (voltage sum versus voltage different) of two sensing pairs, the rotary angle of the surface crack is retrieved with a maximum residual deviation of 3.5%.
A technically sustainable E‐bus based transit system for Indian cities

The exponential increase in the number of internal combustion engine vehicles due to rapid urbanization results in traffic congestions and air pollution. A paradigm shift towards public transportation system using an electric vehicle can be a possible solution for this issue. However, for such a system to be effective, it is necessary to study its impact on the electricity grid, and also to size the subsystems appropriately. Hence, in this work, an E ‐ bus based transportation system with the preliminary sizing of subsystems is proposed. In order to ensure that the proposed transportation system does not over-burden the grid, distributed solar energy generation is used as an additional source. The energy required for transportation system is stored in a high capacity storage device from grid and solar. The high capacity storage device is further used to stabilize the grid through peak shaving and valley filling. The systematic energy flow between subsystems is ensured by using a fuzzy logic control algorithm. The feasibility of the proposed system is analysed for Guwahati city, Assam, India, for its driving pattern and different seasonal variations of grid demand and solar irradiation. The results of the analysis show that with proper sizing and energy management, a viable E ‐ bus based transportation system can be obtained for Indian cities.
Liver transplantation for acute‐on‐chronic liver failure predicts post‐transplant mortality and impaired long‐term quality of life

Among patients with cirrhosis, candidate selection and timing of liver transplantation (LT) remain problematic. Acute‐on‐chronic liver failure (ACLF) is a severe complication of cirrhosis with excessive short‐term mortality rates under conservative therapeutic measures. The role of LT in the management of ACLF is uncertain.
QUANTUM TREATMENT OF THE EFFECTS OF DIPOLE-DIPOLE INTERACTIONS IN LIQUID NUCLEAR MAGNETIC RESONANCE

Experimental observation of anomalous intermolecular cross‐peaks in two‐dimensional solution NMR spectra have attracted significant recent attention. Extremely simple pulse sequences on extremely simple samples with large equilibrium magnetization give resonances in the indirectly detected dimension which are simply impossible in the conventional density matrix framework of NMR. Here we extend a recently proposed density matrix treatment [Science 262, 2005 (1993)] to calculate the exact time evolution for a variety of pulse sequences. This density matrix treatment explicitly removes two fundamental assumptions of the standard theory—it includes the dipolar interaction between spins in solution (which is only partially averaged away by diffusion) and completely removes the high temperature approximation to the equilibrium density matrix [exp(−βH)≊1−βH]. We compare this quantum mechanical treatment to a corrected classical model, which modifies the dipolar demagnetizing field formulation to account for the .
