Determining the Limits and Effects of High-Rate Cycling on Lithium Iron Phosphate Cylindrical Cells

The impacts on battery cell ageing from high current operation are investigated using commercial cells. This study utilised two tests–(i) to establish the maximum current limits before cell failure and (ii) applying this maximum current until cell failure. Testing was performed to determine how far cycling parameters could progress beyond the manufacturer’s recommendations. Current fluxes were increased up to 100 C cycling conditions without the cell undergoing catastrophic failure. Charge and discharge current capabilities were possible at magnitudes of 1.38 and 4.4 times, respectively, more than that specified by the manufacturer’s claims. The increased current was used for longer term cycling tests to 500 cycles and the resulting capacity loss and resistance increase was dominated by thermal fatigue of the electrodes. This work shows that there is a discrepancy between manufacturer-stated current limits and actual current limits of the cell, before the cell undergoes catastrophic failure. This presumably is based on manufacturer-defined performance and lifetime criteria, as well as prioritised safety factors. For certain applications, e.g., where high performance is needed, this gap may not be suitable; this paper shows how this gap could be narrowed for these applications using the testing described herein.
Optimization of oil-in-water nanoemulsion system of Ananas comosus peels extract by D-optimal mixture design and its physicochemical properties

Abstract Ananas comosus (A. comosus) is one of the many commercial crops in Asian countries well-known for its medicinal characteristics, and widely popular in the food industry. Nonetheless, large quantities of the antioxidant rich pineapple peels (PP) are discarded or used as animal fodder, thus the full potential of the PP for nanocosmeceutical applications remain untapped. This study assessed the use of D-optimal mixture design for optimizing droplet size and polydispersity index (PDI) of PP extract nanoemulsion (AcPEN), for four different independent variables (olive oil, grapeseed oil, Tween 80, water). The identified best formulation indicated satisfactory agreement, with the percentage prediction error (PPE) for the actual and predicted values being less than 10%. The optimized AcPEN (OPT-AcPEN) was organoleptically characterized and the Transmission Electron Micrograph corroborated the minimum droplet size and PDI of OPT-AcPEN being <200 nm and < 0.25, respectively. The OPT-AcPEN was stable under different storage conditions for up to 90 days, and the corresponding repeated centrifugation and freeze-thaw tests retaining the recommended pH of between 4 − 6 for topical skin application. Pertinently, the shear thinning and pseudoplastic behavior seen from the rheology results implied the suitability of OPT-AcPEN as a topical cosmeceutical nanoemulsion and could meet user’s requirements.

A Heterogeneous Inductive Power Transfer System for Electric Vehicles with Spontaneous Constant Current and Constant Voltage Output Features

An inductively coupled wireless power transfer system is proposed in this paper, which is designed to comply with the battery’s load characteristics. A loosely coupled transformer with high coupling coefficient is proposed. A heterogeneous compensation topology is proposed which is able to switch between constant current and constant voltage output mode according to the load resistance. The output characteristic curve agrees with the charging curve of the battery in a whole cycle. The proposed topology has a misalignment range of 300 mm where the coupling coefficient is 0.2. A 3 kW experimental platform is established to verify the theoretical analysis, and the experimental results show that the proposed loosely coupled transformer has high coupling coefficient and high power transmission efficiency (95.2% in aligned position) within a large misalignment range, which agrees with the charging scenario of the electric vehicle.
Financial problems associated with food insecurity among public university students in Peninsular Malaysia

Introduction: Food is a necessity for students. Yet, students’ food expenditure is anticipated to be restrained by their financial status. This cross-sectional study aims to determine the prevalence of food insecurity and its determinants among university students attending public universities in Peninsular Malaysia. Methods: Multistage random sampling was used to select respondents from public universities in Peninsular Malaysia. A total of 427 undergraduate students completed a selfadministered questionnaire at four randomly selected universities (Universiti Utara Malaysia, Universiti Kebangsaan Malaysia, Universiti Malaysia Pahang and Universiti Teknologi Malaysia). The questionnaire consisted of information concerning demographic and socioeconomic backgrounds, food security status, eating behaviour, financial literacy, and financial problem among university students. Frequency, chi-square, and logistic regression were used to analyse the variables. Results: Mean age of the respondents was 21.6 years, and 60.9% were found to be food insecure. Gender (χ2=5.415), origin (χ2=3.871), number of siblings (χ2=4.521), financial problem (χ2=42.364), and regular breakfast intake (χ2=5.654) were associated with food security status (p<0.05). Male respondents had 1.5 times (AOR=1.547, 95% CI: 1.006-2.380) the risk of having low food security status. Those with higher financial problems (AOR=3.575, 95% CI: 2.332-5.481) were 3.5 times more likely to be food insecure. Conclusion: The prevalence of food insecurity among public university students in Peninsular Malaysia was significantly high. Thus, intervention studies should focus on students with financial problems. Moreover, establishing a better system for an on campus food pantry or food bank is needed to counter the high prevalence of food insecurity among university students.
Dark and photoassisted Fe3+ -catalyzed degradation of chlorophenoxy herbicides by hydrogen peroxide

The herbicides 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) were degraded in acidic aerated solutions of H 2 O 2 and Fe 2+ or Fe 3+ . Conditions leading to complete mineralization could be achieved using Fe 3+ /H 2 O 2 , which thereby became the focus of the study. Herbicide transformation by Fe 3+ /H 2 O 2 , was sensitive to pH (optimum, 2.7-2.8) and was inhibited by methanol or chloride due to scavenging of the active oxidant, and by sulfate due to complexation of Fe 3+
Tilt order in Langmuir monolayers

Tilt (smectic-C) order has been observed both in experiments and simulations of Langmuir monolayers. We have constructed a mean-field model, based on a system of rigid molecules with both repulsive and attractive interactions, to study this kind of order. Different phase diagrams as well as the limit of infinitely long hard rods at vanishing density (Onsager limit) are studied. We also comment on the possible influence of other degrees of freedom not included in our model
The GIS based Criminal Hotspot Analysis using DBSCAN Technique

Spatially Data mining used efficiently to extract any potential patterns and associations to detect hidden information from multiple sources data. In this paper, data mining Density-based spatial clustering of applications with noise DBSCAN algorithm is emphasised. The importance in this work was using a prototype software to process the giving data into an understandable outcome throw clustering technique, it is a powerful method for criminal activities detection and pattern recognition to get useful information that can help police to reduce crimes. Spatial data mining is practical with geographical crimes data set and processing a large amount of crimes data. Police conventional way was manual and time-consuming using a pin on the wall. Therefore, it has to be developed and merged with advanced techniques. In this study, data mining clustering method was used to examine Baltimore, Maryland’s crimes information. The processed criminal data from the state of Maryland, Baltimore City was 340,924 cases and 16 attributes to reflect the cases between 2012-2018. DBSCAN algorithm is utilized to cluster crimes incidents focused on certain predefined events and the outcome of these clusters employed to find hotspots. The clustering findings are visualized by the GIS to make crimes distribution on the map at real-time for the law enforcement to understand and interact
Remote Warfare and the Retooling of American Primacy

ABSTRACT This paper argues for the utility of remote warfare as a means of analysing the geopolitics of American primacy. Through the use of new technologies and surrogate forces to address security challenges with a minimal military footprint, remote warfare (re)imposes political distance between the United States and the sites of its military interventions. Its constitutive modalities of intervention range from drones and Special Operations Forces to Private Military Security Companies, security cooperation programmes and emerging technologies associated with Artificial Intelligence. As public support for large-scale overseas interventions has dwindled and strategic competition with China has intensified, remote warfare represents a means of ‘retooling’ US primacy, which is both a structural condition and a strategic orientation. As a strategic approach to the use of force, remote warfare enables the American state to project military power in a more flexible and sustainable manner. This has supported the maintenance of US primacy as Washington’s strategic focus has shifted from counterterrorism towards a renewed emphasis on great power competition.
Partition coefficients and the free energy of confinement from simulations of nonideal polymer systems

The investigation of the partitioning equilibrium in real polymer systems by Monte Carlo (MC) simulations is reported. In contrast to ideal chain treatments the factors such as flexibility and excluded volume in real chains, the finite concentration of macromolecules o, and polymer adsorption on pore walls of the attractive strength ∈ w are considered in computations. The free energy change ΔA/kT due to chain confinement in slitlike structures under nonideal conditions is estimated from simulations. The dependencies of the partition coefficient K on λ, the solute to pore size ratio, relevant to the static partitioning and to size exclusion chromatography (SEC), were computed. In all cases the factors considered enhance the partition coefficient K for a given λ and lead to more gradual changes of K with λ; i.e., the resolving power of the nonideal partitioning decreases relative to a case of ideal chain partitioning. The concentration effect on the steric partitioning coefficient K was found to depend markedly on the solvent quality in dilute solutions. In mixed-mode partitioning by a combination of steric exclusion and adsorption, the function K(λ,∈ w ) is computed by a fit of the simulation data. This function properly reproduces for nonideal chains all liquid chromatography regimes, including the critical chromatography. An interpretation of the free energy changes ΔA/kT in nonideal partitioning, based on the loss of conformational and orientational entropies of coils on their confinement, is discussed.
A CONCEPTUALIZATION OF KNOWLEDGE MANAGEMENT STRATEGY TOWARD ORGANIZATION PERFORMANCE IN THE LIBYAN TRANSPORTATION INDUSTRY

This conceptual paper aims to examine the relationship between the knowledge management strategy and organizational performance in Libya transportation industry. Libya’s government policy proposals for public organisation reform have largely failed to encourage the development of information. The transport industry is suffering from a shortage of backward-integrated equipment. Most Arab nations have inherited their transparent authoritative practises from their previous founder legacies. This is despite the way in which the region needs knowledge management as never before due to the evolving way of global aggression. Also, the introduction and use of different information technologies in an enterprise will be the key to conducting knowledge management activities in the transport industry. The promotion of trust among members of intra- and inter-organizational teams is of primary concern for the establishment of a strong and sound knowledge base. It takes some time to establish a desired knowledge culture for the sharing of knowledge and exchange of knowledge. However, only a small section of the public would appreciate gains and any aspect of it could be overlooked by the rest. It should strive to develop the academic resources of the general public and involve people in basic leadership in general. JEL: L10; L25; L91 Article visualizations:
What does ‘Big Three’ tell us about retirement planning skills?

ABSTRACT In this paper, we present the results of financial knowledge assessment from a nationwide survey carried out in Poland in 2019. To measure this phenomenon, we use the well-grounded scale, the ‘Big Three’ financial literacy questions, proposed by Mitchell and Lusardi. The results are similar to those of studies in other countries. However, we find that financial literacy scores poorly predict reasonable answers to the retirement planning question. We present hypotheses to explain this finding and recommend potential solutions.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2): pathogenesis and virus-host interactions

Coronaviruses have posed a global threat in three different periods over the past two decades. Severe Acute Respirato - ry Failure Syndrome (SARS-CoV) was first revealed in 2003. Then, in 2012, Middle East Severe Acute Respiratory Failure Syndrome (MERS-CoV) was detected. In late 2019, it was re - ported that Coronavirus 2 (SARS-Cov-2) was isolated from Severe Acute Respiratory Failure Syndrome. SARS-Cov-2, which causes a much more severe and common infection compared to SARS-Cov and MERS-Cov, remains a global threat until the vaccine is developed. Owing to the ongoing outbreak of SARS-Cov-2, many facts regarding virus-host interactions and pathogenesis of disease, still needed to be addressed in more detail.
Pitch Angle: A Newfound Influential Trait for Image-Based Facial Beauty Perception

One of the most crucial issues in facial beauty study is to find the traits, which determine the perceived attractiveness of a face. During the decades, many traits have been studied extensively, such as proportions, averageness, and symmetry. However, facial beauty seems to be more complex than these traits. In this paper, a face image is represented by a series of interpretable parameters, which are learnt by a CNN based 3DMM fitting algorithm. Based on the SCUT-FBP5500 dataset, we explore the relationship between those parameters and the human rated facial beauty scores. We observe that the pitch angle parameter has a strong correlation with the beauty score. In order to study the causal relationship between the pitch angle and facial beauty, face images with different pitch angles were generated as the stimuli and 39 volunteers were invited to a rating experiment. The results show that the change of the pitch angle has a significant effect on the perceived facial beauty. This finding may explain that head pose plays an important role in the self-portrait shot.
Netrin-1 Ameliorates Postoperative Delirium-like Behavior in Aged Mice by Suppressing Neuroin�ammation and Restoring Impaired Blood Brain Barrier Permeability

Background Postoperative delirium (POD) is a common and serious postoperative complication in elderly patients, of which the underlying mechanism is elusive and without effective therapy at present. In recent years, the neuroin�ammatory hypothesis has been developed in the pathogenesis of POD. Netrin-1, an axonal guidance molecule, has been reported to have strong in�ammatory regulatory and neuroprotective effects. Methods We applied treatment with Netrin-1(45 µg/kg) in aged mice by using the POD model with a simple laparotomy to assess systemic in�ammatory, neuroin�ammation by detecting interleukin-6 (IL-6), interleukin-10 (IL-10), high mobility group box chromosomal protein-1(HMGB-1) and assessing the reactive states of microglia, permeability of blood-brain barrier (BBB) by detecting cell junction proteins and leakage of dextran, and behavior of the aged mice. Results We found that a single dose of Netrin-1 prophylaxis decreased the expression of IL-6 and HMGB-1, and upregulated the expression of IL-10 in peripheral blood, hippocampus and prefrontal cortex. Nerin-1 reduced activation of microglia cells in the hippocampus and prefrontal cortex and improved the POD-like behavior. Besides, Netrin-1 also attenuated the anesthesia/surgery-induced increase in BBB permeability by up-regulating the expression of tight junction-associated proteins such as ZO-1, claudin-5, and occludin. Conclusions These �ndings con�rm the anti-in�ammatory and BBB protective effects of Netrin-1 in an in�ammatory environment in vivo and provide better insights into the pathophysiology and potential treatment of POD.
Raman Scattering of Internal Dynamics in Spinel Zn2TiO4 Nanostructures

We present here the results of the Raman study of lattice dynamics and local compositional fluctuations in cubic spinel Zn2TiO4 nanostructures. The observed Raman modes of the spinel structure are identified and attributed to local vibrational modes. Additionally, the analysis of the nonpolar E2(H) (∼437 cm−1, 54.2 meV) and A 1g (∼716 cm−1, 88.7 meV) modes are made and contributed to lattice deformation associated with the distinct coordination preferences of Zn and Ti.
Liminality and Canaanite Cultic Spaces: Temple Entrances, Status Transformations and Ritual in Threshold Contexts

ABSTRACT This article investigates the applicability of the concept of liminality to the archaeological analysis of temple thresholds, with a primary focus on the Bronze Age southern Levant. Previously, studies on cultic spaces have emphasized temple cellae as the central focal point of ritual. In contrast, ritual performed at temple thresholds has largely been an ignored phenomenon. This study presents theoretical, textual, and archaeological data to support the argument that thresholds, in general, elicited ritual activity, and that within temple contexts, a wide range of rituals were conducted, and offerings presented. After investigating the topic of liminality in rites of passage, an array of ANE texts will be used to shed light on threshold rituals. This is followed by a presentation of archaeological studies that have attempted to apply the concept of liminality to the archaeological record. Bronze Age temples from two sites, Lachish and Hazor, will be used as case studies to investigate whether there is evidence from the southern Levant for ritual in entrances and thresholds. The results of this study demonstrate that temple thresholds in Canaan did in fact function as liminal spaces within which ritual was conducted. Additionally, this study identifies an important distinction between rituals that were performed in the liminal space of thresholds and those that were performed in the temple’s cella. Ritual in the cella was theocentric, with the primary focus on the deity, while ritual at thresholds was anthropocentric, concerned with humans and their status transformations.
Some inherited disorders in pacing horses in Turkey

: This study was carried out to detect the presence of mutant alleles of polysaccharide storage myopathy (PSSM) and severe combined immunodeficiency (SCID) disorders in pacing horses raised in different regions of Turkey. Blood/hair samples from 264 (182 Indigenous, 31 Iranian, 24 Afghan, and 27 Bulgarian) pacing horses aged 4 and over were used. As a result of the study, a mutation-heterozygosis (GA) in the GYS1 gene related to PSSM disease was detected in one of the pacing horses (Bulgarian horse). No deletions were observed in the DNA-PKcs gene region in the pacing horses for SCID disease. This study has been carried out to identify the status of two inherited disorders in pacing horses in Turkey. It was determined that there are no mutant genes in indigenous pacing horses, in terms of PSSM and SCID disorders, which are the major hereditary disorders in horses.
Effect of Gamma Irradiation on the Physical Properties of PVA Polymer

Polyvinyl alcohol (PVA) films were prepared by casting method. The optical properties was measured in the wavelength rang of (200–900) nm, by using UV-visible spectroscopy. The effect of irradiation lead to degradation on the physical properties such as absorbance, transmittance, refractive index, extinction coefficient in addition of the real and imaginary part of dielectric constant was studied. This study reveals that all these parameters affected by the increasing of them irradiation, and also found that the optical energy gap has been increased with the increasing of the irradiation. The structural properties are studied by using XRD, FTIR spectrum, and FESEM.
The impact of intellectual property types on the performance of business start-ups in the United States

Using a large, longitudinal panel of US start-ups collected between 2004 and 2011, this article shows the extent to which intellectual property (IP) types, for example trademarks, patents, copyrights and outward licensing, enhance multidimensional performance. An ordered probit analysis corrected for sample selection bias, estimates performance to derive the following conclusions. First, trademarks and out-licensing IP types increase a firm’s chances of being a high performer, confirming the importance of certain forms of IP protection for start-ups. Second, patenting significantly reduces the chances of being a high performer, suggesting patenting has limited performance benefits for start-ups. Third, few performance synergies exist in the joint use of IP types, suggesting that strong complementarities among IP types are limited. While out-licensing patents and out-licensing copyrights increase performance, out-licensing patents and out-licensing trademarks diminish it. Furthermore, registering more trademarks and out-licensing more trademarks also diminishes performance, suggesting start-up firms should keep trademarks in-house.
