Use of Field Portable X-Ray Fluorescence Spectrum Analysers for Grade Control — A Presentation of Case Studies

This paper presents recent case study data collected by field portable x-ray fluorescence spectrum analysers (FPXRF) as part of grade control activities at three separate (nickel, copper and copper/gold) mining operations. FPXRF has been under utilised for grade control in recent years, largely because the success of early versions of FPXRF was limited to a few metals (eg tin). Efforts to utilise these early versions for other metals was largely unsuccessful and created a perception that FPXRF could not be utilised more broadly within the mining sector and specifically the area of grade control. The structural setting of the analytical function within mining operations has also contributed to the under utilisation of more recent FPXRF instrumentation. The concept of FPXRF as a grade control tool straddles the boundaries of the geology and laboratory departments. As such, this option is often not considered as part of an assessment of grade control procedures for new and existing mining operations. This paper assesses data collected by Australian and New Caledonian miners using FPXRF technology as part of the grade control function and concludes that FPXRF can provide operational and cost benefits to certain mining operations.
Sleep quality and body mass index of nurses: a cross-sectional study

Aim: The aim of this study was to determine the relationship between nurses’ sleep quality and body mass index. Design: This is a cross-sectional study. Methods: This study was conducted with 583 nurses working in a single hospital. It was conducted between July 2018 and June 2019. Results: Among the nurses participating in the study, 69.1% of nurses were found to have poor sleep quality. Body mass index was within normal range in 55.4% of nurses. Nurses working in intensive care unit / operation room / emergency units, nurses working for less than 10 years, nurses working on nights shifts have more normal body weights. There were statistically significant differences between body mass index ratios and sleep quality scores. Conclusion: Sleep quality was found to be negatively affected as working hours increased. In addition, a positive correlation was observed between sleep quality and BMI. Sleep quality increased as BMI increased.
Assessing the Level of Nutrition Knowledge and Its Association with Dietary Intake in University Students

Objective: This cross-sectional study was conducted to assess the level of nutrition knowledge and examine the relationship between nutrition knowledge and dietary intake in university students. Materials and Methods: The sample consisted of 300 students, aged 18-35 years old from different academic departments (males: 138, 46%; females: 162, 54%). The student’s general characteristics were asked by using a questionnaire, and anthropometric measurements were taken. Energy, macronutrient, and food consumption were estimated through 24-hour dietary recall. Results: The means body mass index of the participants was 22.4 ± 3.1 kg/m 2 . The total score of nutrition knowledge for all sections was 56.5±13.2 points out of 110. In comparison with males, score for nutrition knowledge was higher in females (54.1±13.3, and 58.6±12.8, respectively) (p<0.01). It was shown that students with higher scores had lower energy, carbohydrate, and sugar intakes (p<0.05). There were no significant differences between nutrition knowledge and protein and fat intake. Also, a significant relationship between nutrition knowledge level and food group consumption was not found. Conclusion: We suggest that training programs and policies should be planned and implemented for university students to improve their nutrition knowledge. Enhancing nutrition knowledge of students can help to promote healthy eating in a community.
Measuring Project Success in the Construction Industry

Abstract: The measurement of project success in the construction industry has traditionally been grounded in the industry-accepted classic objective success metrics: cost, schedule, performance, and safety. Initial research has indicated that there are more subjective considerations that, while being difficult to quantify, can have an important impact on perceptions of project success. During ongoing project management research, the authors recognized the need for a measurement tool that would account for subjective as well as objective metrics in assessing project success. The tool would have to provide the flexibility necessary to account for the fact that every project is different. The resulting Construction Project Success Survey (CPSS) instrument is designed to investigate how experienced construction project management personnel perceive project success, both objectively and subjectively. The engineering manager can use this tool to identify important success metrics before the start of a project, and to evaluate the level of success achieved at project completion.
Characterization of thin textured tunnel oxide prepared by thermal oxidation of thin polysilicon film on silicon

In this paper, the characteristics of thin textured tunnel oxide prepared by thermal oxidation of thin polysilicon film on Si substrate (TOPS) are studied. Because of the rapid diffusion of oxygen through the grain boundaries of the thin polysilicon film into the Si substrate and the enhanced oxidation rate at the grain boundaries, the oxidation rate of the TOPS sample is close to that of a normal oxide grown on a (111) Si substrate. Also, a textured Si/SiO/sub 2/ interface is obtained. The textured Si/SiO/sub 2/ interface results in localized high fields and causes a much higher electron injection rate. The optimum TOPS sample can be obtained by properly oxidizing the stacked /spl alpha/-Si film, independent of the substrate doping level. Also, the optimum TOPS sample exhibits a smaller electron trapping rate and a lower interface state generation rate when compared to the sample from a standard tunnel oxide process. These differences are attributed to a lower bulk electric field and a smaller injection area in the TOPS samples.
Influence of Hydraulics on Electric Drive Operational Characteristics in Pump-Controlled Actuators

Transitioning from a valve- to pump-controlled system has been observed in working hydraulics to reduce energy consumption and accelerate the response to decarbonization requirements in Non-road Mobile Machinery (NRMM). The utilization of an electric motor as a prime mover significantly enhances the chances of completing this task. While the concept of combining hydraulics with an electric motor is not new, the functionality of electro-hydraulics can be improved due to multidisciplinary domains, the impact of the electric drive and its control is usually underestimated. Thus, this study aims to evaluate the influence of hydraulics on electric drive operational characteristics in pump-controlled actuators. It utilizes an electro-hydraulic model and simulation study under various conditions, a stability analysis, and a Pulse Width Modulation (PWM) of the frequency converter (FC) evaluation on a selected variable speed pump-controlled actuator to demonstrate the influence of hydraulics on an electric drive. Experimental validation of the model demonstrated an acceptable accuracy of 5%. Moreover, the stability analysis indicated a rise time of about 0.051 s, an overshoot of 0.53%, a transient process time of 0.13 s, and a steady-state value difference of 0.16%; all of which guarantees stable operation of the electric drive with a hydraulic load. In addition, an optimal PWM of an FC frequency of 5 kHz was selected to guarantee accurate speed control with minimum overshoot.
Formulation and Evaluation of Kaempferol Loaded Nanoparticles against Experimentally Induced Hepatocellular Carcinoma: In Vitro and In Vivo Studies

The present study was designed to prepare Kaempferol loaded nanoparticles (KFP-Np) and evaluate hepatoprotective and antioxidant effects in hepatocellular carcinoma models. KFP was encapsulated with hydroxypropyl methylcellulose acetate succinate (HPMC-AS) and Kollicoat MAE 30 DP polymers to prepare nanoparticles (Nps) by quasi-emulsion solvent diffusion technique (QESD). The prepared Nps were evaluated for different pharmaceutical characterization to select the optimum composition for the in vivo assessment. An animal model of cadmium chloride (CdCl2)-induced hepatocellular carcinoma in Male Sprague Dawley rats was used in vivo to test the antioxidant and hepatoprotective capacity of free and encapsulated KFP. The prepared Npsshowed nanometric size, low PDI, high drug load as well as encapsulation with a better drug release profile. There was a significant decrease in the increased serum levels of alanine transaminase (ALT), total bilirubin (TBiL), and aspartate transaminase (AST), and the lipid peroxidation’s (MDA) level was attenuated, and levels of markers of the cell antioxidant defence system were restored including Glutathione S-transferase (GST), glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) via oral pre-treatment with KFP-Np (50 mg/kg b.w. (body weight), 6 weeks). KFP-Np significantly declines an mRNA expression of interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-alpha (TNF-α) as well as decreased nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) protein expression. It also upregulated the mRNA expression and protein expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1). While comparing the protective effects of KFP encapsulated in Kollicoat MAE 30 DP and HPMC-AS, Nps was found to be betterthan free KFP. Insummary, result indicate that encapsulation of KFP in NPs provides a potential platform for oxidative stress induce liver injury.
Intermittent Exotropia: A Review of the Natural History and Non-surgical Treatment Outcomes

Intermittent exotropia of the divergence excess type is the most common form of exotropia. Given the intermittent nature of this deviation, and that it can be controlled by fusional vergence but has the potential to develop sensory anomalies such as suppression, management options include non-surgical as well as surgical means. The aims of non-surgical or orthoptic treatment are to improve fusion, eradicate suppression and or teach control of the deviation, in order to decrease the frequency of the manifest phase and improve motor alignment for near and distance. This review focuses on the outcomes of various non-surgical treatments, including orthoptics, and discusses the natural history of intermittent exotropia which invariably has implications for management.
The importance of cultural psychological perspectives in pain research: Towards the palliation of Cartesian anxiety

Despite widespread awareness of the psychological dimensions of pain, researchers often and easily slip into essentializing understandings that treat pain as a purely physiological experience that can be isolated within experimental research. This drive towards scientific objectivity, while at times of tremendous utility, can also limit our understanding of pain to reductionistic conceptualizations that in effect deny the subjective and even the psychological dimensions of pain. In other words, researchers often attempt to understand pain by means of empirical, scientific explanations, while being simultaneously aware that such an approach cannot grasp the phenomenon in its entirety. This yearning for deeper, ontological understanding in a world that admits of only empirical, scientific explanations has been called Cartesian anxiety. In the current study, it is argued that cultural psychology can help to alleviate this Cartesian anxiety by helping us to appreciate the psychological aspects of pain as dynamic processes of meaning making.
DESIGN OF MSMEs DEVELOPMENT THROUGH PROFIT SHARING SCHEMES

The purpose of this study is to find the design of Micro, Small, and Medium Enterprises (MSMEs) development through profit-sharing schemes seen from the perspective of MSMEs actors in East Java Indonesia. This research was conducted in East Java, Indonesia, selecting research locations carried out randomly and then determining the respondents proportionally. Respondents in this study were 220 MSMEs actors using the proportional random sampling technique. The data analysis technique used is warped partial least square to look for the design partially and through intervening. This study uses mudarabah financing and musharakah financing as exogenous variables, principles of profit-sharing distribution as intervening variables, and development of MSMEs as endogenous variables. The findings in this study are the contribution of profit-sharing distribution as an intervening variable in the development of MSMEs through the mudarabah financing scheme and the musharakah financing with the dominance of the musharakah financing. The ideal design of the development of MSMEs is the use of mudarabah financing and musharakah financing by applying the profit-sharing distribution principle following the principles of Islamic Sharia.
XV. On systems of linear indeterminate equations and congruences

The theory of the solution, in positive or negative integral numbers, of systems of linear indeterminate equations, requires the consideration of rectangular matrices, the constituents of which are integral numbers. It will therefore be convenient to explain the meaning which we shall attach to certain phrases and symbols relating to such matrices. A matrix containing p constituents in every horizontal row, and q in every vertical column, is a matrix of the type q × p. We shall employ the symbol ∥ q × p A∥ or (when it is not necessary that the type of the matrix should be indicated in its symbol) the simpler symbol ∥A∥ to represent the matrix ∥ A1, 1, A1, 2,. A1, p∥ ∥ A2, 1, A2, 2,. A2, p∥ ∥ Aq, 1, Aq, 2,. Aq, p∥ If ∥A∥ and ∥B∥ be two matrices of the same type, the equation ∥A∥ = ∥B∥ indicates that the constituents of ∥A∥ are respectively equal to the constituents of ∥B∥; whereas the equation |A|=|B| will merely express that the determinants of ∥A∥ are equal to the corresponding determinants of ∥B∥. The determinants of a matrix are, of course, the determinants of the greatest square matrices contained in it; similarly, its minor determinants of order i are the determinants of the square matrices of the type i × i that are contained in it. Matrices of the types n×(m + n) and m × (m + n) are said to be of complementary types; if ∥A∥ and ∥B∥ be two such matrices, we shall employ the equation |A| = |B| to express that each determinant of ∥A∥ is equal to that determinant of ∥B∥, by which it is multiplied in the development of the determinant of the square matrix ∥AB∥. When m and n are both uneven numbers, the signs of the determinants and |AB| and |BA| are different: this occasions a certain ambiguity of sign in the interpretation of the equation |A| = |B|, which, however, will occasion no inconvenience. If m = n, the matrices ∥A∥ and ∥B∥ are at once of the same, and of complementary types; so that, in this case, the equation |A| = |B| may stand for either of two very different sets of equations; but this also is an imperfection of the notation here employed, which it is sufficient to have pointed out. If k denote any quantity whatever, it is hardly necessary to state that the equality |A| = k × |B| implies that determinants of |A| are respectively k times the corresponding determinants of ∥B∥.
Up-scaling production of certified potato seed tubers in Kenya: Potential of aeroponics technology

Unavailability of certified seed tubers is a major constraint to potato production in Kenya. This compels most farmers to use planting materials from informal sources such as previous harvests, local markets and neighbours. Kenya Agricultural Research Institute (KARI), Tigoni has the national mandate to produce basic seed tubers but can only supply much less than 1% of the national seed requirements. In order to improve on the situation, aeroponics technique was introduced to enhance production of prebasic seeds from tissue culture plantlets. The aeroponics unit is still in experimental stages and is being evaluated for productivity and profitability. Some results show that aeroponics can increase production of prebasic minitubers. However, the aeroponic technology needs further and complete evaluation in terms of productivity, profitability and sustainability. Key words: Aeroponics, certified seed, Kenya Agricultural Research Institute (KARI), Tigoni, minitubers, potatoes.
Electron mobility in an AlGaN/GaN two-dimensional electron gas. I. Carrier concentration dependent mobility

The transport properties of two-dimensional electron gas (2-DEG) at the AlGaN/GaN interface were studied by characterizing the 2-DEG mobility dependence on carrier concentration, n/sub s/, and temperature. High-quality AlGaN/GaN heterostructures were grown, and heterostructure field effect transistors (HFETs) using a Fat FET geometry were fabricated. Measurements of 2-DEG mobility were performed by magnetoresistance and capacitance-conductance. In order to understand the dominant transport factors, the mobility was modeled using different scattering mechanisms and compared to our results. It is found that mobility dependence on n/sub s/ shows a bell-shape behavior over the whole temperature range. For low n/sub s/ the mobility is dominated by Coulomb interaction from interface charge, and at high n/sub s/ the mobility is dominated by interface roughness. Using previously reported experimental values of interface charge and interface roughness in our modeling, we show good agreement with mobility measurement results. Scattering from interface states in AlGaN/GaN heterostructures, seems to be related to the high polarization field in the heterointerface. At temperatures higher than 200K polar optical phonon scattering dominates the transport, yet both interface charge and roughness affect the mobility at the low and high n/sub s/, respectively.
Developing and Aligning a KM Strategy

While many firms have introduced knowledge management (KM) initiatives, very few are actually approaching it in a way that links KM initiatives directly to their organizational business strategy. Developing an effective KM strategy requires careful analysis and thorough planning as well as alignment with the organization's overall business strategy and with other functional strategies. To explore and understand the development and alignment of KM strategy, we conducted research using focus group methodology. Our research sheds light on the scope, development and execution of KM strategy in today's organizations and offers guidance to the academic as well as practitioner audiences
Ergonomics evaluation of modified industrial helmets for use in tropical environments

Hotness, weight, fitting problems etc., have been found to be the chief causes of the unpopularity of industrial safety helmets in tropical environments in developing countries (DC). Some selected safety helmets manufactured in industrialized countries (IC) were modified to provide extra head ventilation and to reduce weight, in order to make them more acceptable to users in hot environments. The modified helmets were subjected to ergonomics evaluation both objectively and subjectively in the laboratory (in simulated tropical conditions) as well as in the field situation. There was evidence that white helmets had some advantages in comfort, viz. reduction of hotness, compared to the other colours, e.g. red, green etc., when worn in the presence of radiant heat in the laboratory. Ventilation holes provided at the top of the shell seemed to reduce the greenhouse effect within the helmet shell which therefore felt less uncomfortable than a fully covered helmet. Even with a small reduction of weight, such as .
Modeling the Effects of Deep Chiseling with DRAINMOD for Alluvial Soils

DRAINMOD is a drainage model that has been widely used in the shallow water table regions of the U.S., including the southeastern U.S. Therefore, it is important that DRAINMOD realistically simulate the water balance components for alluvial soils that are prone to surface seal formation, which are the predominant soils in much of the southeastern U.S. In this study, DRAINMOD 5.1 was modified to address the problems associated with the assumption of constant vertical saturated hydraulic conductivity (Ks) and constant maximum surface depressional storage (STMAX) for these alluvial soils. The first objective was to modify DRAINMOD 5.1 to incorporate the effects of deep chiseling (Ks and STMAX vary) in order to improve its prediction of infiltration and surface runoff. The second objective was to evaluate the modified DRAINMOD models with dynamic Ks and STMAX subroutines (DRAINMOD-Ks, DRAINMOD-STMAX, and the combined DRAINMOD-Ks-STMAX), using two years (Sept. 1995 to Nov. 1996 and Nov. 1996 to Nov. 1997 when deep chiseling was carried out) of measured surface runoff data from the USDA-ARS Ben Hur research site. Simulations by DRAINMOD 5.1 were compared with those by DRAINMOD-Ks, DRAINMOD-STMAX, and DRAINMOD-Ks-STMAX to further determine the effect of the modifications on surface runoff and infiltration predictions. In general, DRAINMOD-STMAX, DRAINMOD-Ks, and DRAINMOD-Ks-STMAX improved surface runoff prediction by 57%, 73%, and 82%, respectively, in the 1995-1996 season and by 27%, 45%, and 62%, respectively, in the 1996-1997 season.
Asynchronous Decentralized SGD with Quantized and Local Updates

Decentralized optimization is emerging as a viable alternative for scal-able distributed machine learning, but also introduces new challenges in terms of synchronization costs. To this end, several communication-reduction techniques, such as non-blocking communication, quantization, and local steps, have been explored in the decentralized setting. Due to the complexity of analyzing optimization in such a relaxed setting, this line of work often assumes global communication rounds, which require additional synchronization. In this paper, we consider decentralized optimization in the simpler, but harder to analyze, asynchronous gossip model, in which communication occurs in discrete, randomly chosen pairings among nodes. Perhaps surprisingly, we show that a variant of SGD called SwarmSGD still converges in this setting, even if non-blocking communication , quantization , and local steps are all applied in conjunction , and even if the node data distributions and underlying graph topology are both heterogenous . Our analysis is based on a new connection with multi-dimensional load-balancing processes. We implement this algorithm and deploy it in a super-computing environment, showing that it can outperform previous decentralized methods in terms of end-to-end training time, and that it can even rival carefully-tuned large-batch SGD for cer-tain tasks.
