The effect of social capital on innovation through the mediation of ambidexterity and knowledge sharing in cement industry

Indonesia's economy is in a precarious state, made worse by the presence of the corona virus disease 2019 (Covid-19) pandemic. As a result, it is critical for businesses to be able to adapt to changes in an uncertain business environment. One option for the business to endure is through innovation. Previous study has established that social capital, the ability of the work team to be ambidextrous and knowledge sharing play a critical role in the creation of innovation inside the organization. The purpose of this study is to examine the effect of social capital on innovation through the mediation of ambidexterity and knowledge sharing in work teams at PT Indocement Tunggal Prakarsa Tbk, one of the largest private cement companies in Indonesia. The company operates in an unstable environment due to the global crisis, politics, price competition, and excess cement production capacity in Indonesia since 2016. This research is quantitative research with purposive sampling method using Structural Equation Modeling (SEM) analysis with Partial Least Square (PLS) method to test the hypothesis. The study's findings demonstrate that social capital can influence the generation of innovation when it is mediated through ambidexterity and knowledge sharing. This research is expected to assist enterprises in the Indonesian cement sector in surviving by fostering innovation within each work team.

Effect of three storage methods on physical and chemical properties of colostrum from Bos indicus cows

ABSTRACT: Maternal colostrum provides the neonate with immunoglobulins, essential for passive immunity. However, storage and handling of colostrum can alter its physical and nutritional characteristics. The aim of this study was to evaluate the effects of three conservation methods on colostrum density, pH, total antioxidant capacity (TAC), protein (PP) and lipid peroxidation (LP). Colostrum samples were collected from 15 Bos indicus cows, and divided into three aliquots for storage using three methods: refrigeration at 4°C, freezing at -20°C, and lyophilization. For each method, four evaluation times were performed: day (d) 5, 10, 15, and 20 for refrigeration and d 15, 30, 45, and 60 for freezing and lyophilization. pH and density analyses were performed at each evaluation time for each method. On d 0 and 15 of storage, TAC, LP, and PP analyses were performed. A generalized linear model, Tukey’s test for means comparisons, and a Pearson correlation analysis were conducted. A decrease in refrigerated colostrum pH was observed on d 15. Density of the lyophilized colostrum decreased, as compared with that of frozen colostrum. Lyophilization exhibited the lower PP values of samples, whereas refrigeration presented the highest values of LP and PP. No differences in colostrum TAC were observed between storage methods. A positive correlation between PP and colostrum density and a negative correlation between colostrum density and TAC were found. It was concluded that both freezing and lyophilization are suitable storage methods for bovine colostrum, as they limit proteins and lipids oxidation, and maintain the TAC of fresh colostrum.
Comb decimator design based on symmetric polynomials with roots on the unit circle: Two‐stage multiplierless design and improved magnitude characteristic

This paper presents a theoretical background for design of comb decimator based on theorem of symmetric polynomials with roots on the unit circle. A simple multiplierless filter, called zero‐separation (ZS) filter, which separates doubled comb zeros, is derived. The separation of doubled comb zeros improves comb aliasing rejection. In order to get more benefits of the ZS filter, a two‐stage structure is considered. The classic comb filters are in both stages of the proposed structure. Additionally, in the second stage, a ZS filter is inserted to improve comb aliasing rejection. The passband droop is compensated by the compensator which works at low rate and is designed using particle swarm optimization (PSO). The method is illustrated with various examples. The comparisons with methods from literature prove the benefits of the proposed work.
The National Ignition Facility: Transition to a User Facility

The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) has been operational since March 2009 and has been transitioning to a user facility supporting ignition science, high energy density science (HEDS), national security applications, and fundamental science. The facility has achieved its design goal of 1.8 MJ and 500 TW of 3ω light on target, and has performed target experiments with 1.9 MJ at peak powers of 410 TW. The facility is on track to perform over 200 target shots this year in support of all of its user communities. The facility has nearly 60 diagnostic systems operational and has shown flexibility in laser pulse shape and performance to meet the requirements of its multiple users. Progress continues on its goal of demonstrating thermonuclear burn in the laboratory. It has performed over 40 indirect-drive experiments with cryogenic-layered capsules. New platforms are being developed for HEDS and fundamental science. Equation-of-state and material strength experiments have been done on a number of materials with pressures of over 50 MBars obtained in diamond, conditions never previously encountered in the laboratory and similar to those found in planetary interiors. Experiments are also in progress investigating radiation transport, hydrodynamic instabilities, and direct drive implosions. NIF continues to develop as an experimental facility. Advanced Radiographic Capability (ARC) is now being installed on NIF for producing high-energy radiographs of the imploded cores of ignition targets and for short pulse laser-plasma interaction experiments. One NIF beam is planned for conversion to two picosecond beams in 2014. Other new diagnostics such as x-ray Thomson scattering, low energy neutron spectrometer, and multi-layer reflecting x-ray optics are also planned. Incremental improvements in laser performance such as improved optics damage performance, beam balance, and back reflection control are being pursued.
Association between human leukocyte antigen class II (HLA-DRB and -DQB) alleles and outcome of exposure to Mycobacterium tuberculosis: a cross-sectional study in Nairobi, Kenya

Introduction human leukocyte antigen (HLA) class II alleles play an important role in the early immune response to tuberculosis (TB) by presenting antigenic peptides to CD4+ T cells, hence polymorphisms in those genes can influence the efficiency of the immune response to infection and progression to active disease. Methods an analytical cross-sectional study of adult pulmonary tuberculosis (PTB) patients at Mbagathi County Hospital, Nairobi and their HHCs. Sociodemographic data were captured on questionnaires and clinical data extracted from patient files. Intravenous blood samples were drawn for interferon-gamma release assay (IGRA) to determine latent tuberculosis infection (LTBI) among HHCs, and for extraction of DNA used in typing of HLA-DQB1 and HLA-DRB1 alleles by PCR sequence specific primer amplification. Chi-square and Fisher's exact test were used to compare the HLA type II allele frequencies of LTBI negative HHCs, LTBI positive HHCs and active TB patients. Logistic regression was used to adjust for HIV status. Results the HLA-DQB1 and HLA-DRB1 alleles were analyzed in 17 PTB and 37 HHCs. Nineteen (19) HHCs were LTBI positive, while 18 were LTBI negative. The frequency of DRB3*1 was 0.17-fold lower [95% CI=0.03-0.83] among PTB patients compared to HHCs before adjustment for HIV status (p=0.048). The frequency of the DRB5*2 allele was significantly higher (p=0.013) among PTB patients (23.5%) compared to HHCS (0.00%). After adjusting for HIV status, the frequency of DRB1*14 was 12-fold higher [95% CI=1.11-138.2] among PTB patients compared to HHCs (p=0.040). Conclusion the higher frequencies of HLA-DRB5*2 and HLA-DRB1*14 alleles in PTB patients suggest a likely association with progression to active PTB. The higher frequency of HLA-DRB3*1 allele among LTBI negative HHCs shows its likely protective role against M. tuberculosis infection in this population.
Short-term operational planning framework for virtual power plants with high renewable penetrations

This study proposes a two-stage operational planning framework for the short-term operation of the virtual power plant (VPP). In the first stage, a stochastic bidding model is proposed for the VPP to optimise the bids in the energy market, with the objective to maximise its expected economic profit. The imbalance costs of the VPP are considered in the bidding model. In the second stage, a model predictive control (MPC)-based dispatch model is proposed to optimise the real-time control actions. In the real-time dispatch model, the real-time information of the resources is continuously updated, and the deviations between the actual energy output and the contracted energy over the MPC control horizon are minimised. The simulation results prove the efficiencies of the proposed method.

A comparison of running economy across seven highly cushioned racing shoes with carbon-fibre plates

Abstract Recent advancements in running shoe technology, particularly in the Nike Vaporfly, have been shown to improve running economy. Other brands have now also developed new, advanced shoes with thicker midsole foams intended to be more compliant and resilient, along with a carbon-fibre plate. However, none of these new shoes have been compared to the Vaporfly in terms of running economy. Therefore, we compared running economy among seven different highly cushioned racing shoes with a carbon plate: Hoka Rocket X (Hoka RX), Saucony Endorphin Pro (Saucony EP), Nike Alphafly (Nike AF), Asics Metaspeed Sky (Asics MS), Nike Vaporfly Next % 2 (Nike VF2), New Balance RC Elite (New Bal RC), Brooks Hyperion Elite 2 (Brooks HE2) and 1 traditional racing shoe: Asics Hyperspeed (Asics HS) in twelve male runners (5k best: 16.0 ± 0.7 min) during two lab visits. Shoes were tested in a random sequence over 8 × 5-min trials (16 km·h−1; 5-min rest between trials) on visit 1, and in the reverse/mirrored order for visit 2. Metabolic and running mechanics data were collected and averaged across visits. V̇O2 (ml·kg−1·min−1; % change from Asics HS) was significantly different across shoes. Hoka RX (51.67 ± 2.07) and Brooks HE2 (51.42 ± 1.72) did not differ from Asics HS (51.71 ± 2.02). While Saucony EP (50.93 ± 1.82; −1.48 ± 0.72%) and New Bal RC (50.99 ± 1.83; −1.37 ± 0.78%) were statistically better than Asics HS, they were inferior to Nike AF (50.13 ± 1.86; −3.03 ± 1.48%), Nike VF2 (50.29 ± 1.72; −2.72 ± 1.02%), and Asics MS (50.39 ± 1.71; −2.52 ± 1.08%). From these data, it appears most running shoe companies have not yet caught up to the advantages conferred by the Nike VF2.
The exploration-exploitation trade-off in sequential decision making problems

Sequential decision making problems often require an agent to act in an environment where data is noisy or not fully observed. The agent will have to learn how different actions relate to different rewards, and must therefore balance the need to explore and exploit in an effective strategy. In this report, sequential decision making problems are considered through extensions of the multi-armed bandit framework. Firstly, the bandit problem is extended to a Multi-Agent System (MAS), where agents control individual arms but can communicate potentially useful information with each other. This framework allows for a better understanding of the exploration-exploitation tradeoff in scenarios where there are multiple agents interacting in a noisy environment. To this end, we present a novel strategy for action and communication decisions and we demonstrate the benefits of such a strategy empirically. This motivates a theoretical analysis of one-armed bandit problems, to develop ideas of how different strategies are optimally tuned. Specifically, the expected rewards of e-greedy strategies are derived, as well as proofs governing their optimal tuning.
Physico-mechanical characterization and thermal property evaluation of polyester composites filled with walnut shell powder

This paper reports on the processing and overall characterization of walnut shell powder (WSP) filled polyester composite. The effects of this filler on the properties of polyester resin are studied by conducting various characterization tests under controlled laboratory conditions. The composite formation mechanism has been explained by the interpretation of Fourier transform infrared (FTIR) spectroscopic and X-ray Diffraction (XRD) analysis. The study reveals that the incorporation of WSP particles modifies the density and porosity of the composites along with their tensile, compressive, flexural, and impact strengths. Thermo-gravimetric analysis (TGA) is done on the samples to get an insight into their thermal stability. Measurement of thermal conductivity is carried out on samples of different compositions, and it is found that the inclusion of walnut shell powder leads to significant improvement in the thermal insulation capability of polyester resin. It is recorded that with an increase in the WSP content from 0 to 20 wt. % in polyester, the value of the effective thermal conductivity (K eff ) drops by about 42%. It is further seen that with the incorporation of WSP, the coefficient of thermal expansion (CTE) of polyester is substantially lowered.

Effect of a physical exercise program on plasma concentration of adiponectin in overweight and obese children

Adiponectin is considered a biomarker of health status, and high levels are associated with good health. Science discusses the results on the effects of physical activity on increasing adiponectin levels, especially in child with obesity. The scope of the present study was to evaluate a physical exercise intervention program, after 10 months of duration, in the plasma concentration of adiponectin in students from six to nine years of age with overweight and obesity. This is a randomized clinical study of a near-experimental intervention of the type before and after. The physical exercise resulted in a significant reduction in the percentage of body fat (%BF) and triglycerides. Adiponectin there was a non-significant increase. The present study showed that the practice of physical exercise did not increase adiponectin levels, but was responsible for a great improvement in the children lipid profile and reduction in %BF.
Carbohydrate Mouth Rinse Increases High but Not Low Intensity Repetitions to Failure in Resistance-Trained Males

Carbohydrate mouth rinsing (CMR) has been shown to enhance exercise performance. However, the influence of CMR on repetitions to failure with different intensities (40% or 80% of 1 RM) is unknown. Therefore, the purpose of this study was to examine the effects of a 6% CMR solution on muscular endurance assessed at 40% and 80% of 1 RM in resistance-trained males. Sixteen resistance-trained males (age: 25 ± 3 years, height: 182 ± 6 cm, body mass: 86 ± 3 kg, body fat: 16 ± 3%, bench press 1 RM: 106 ± 16 kg, resistance training experience: 5 ± 1 years) completed four conditions in random order. The four conditions consisted of ten seconds of mouth rinsing with 25 mL solutions containing either maltodextrin or placebo (sweetened water) prior to performing a bench press muscular endurance test at either 40% of 1 RM or 80% of 1 RM. Total repetitions, heart rate (HR), ratings of perceived exertion (RPE), glucose (GLU) and felt arousal (FA) were recorded for each condition. There was a significant condition by intensity interaction (p = 0.02). CMR significantly increased total repetitions compared with placebo at the higher intensity (80% of 1 RM; p = 0.04), while there was no effect at the lower intensity (p = 0.20). In addition, HR, RPE, GLU and FA did not differ between conditions or across intensities (p > 0.05). In conclusion, CMR-enhanced muscular endurance performed at higher but not lower intensities.
Precast Concrete Members With Welded Plate Connections Under Reversed Cyclic Loading

94 Precast concrete beams with dry joints, designed for multistory buildings located in a seismic area, were tested under reversed cyclic loading. In the original design, the connection was intended to transfer both shear and moment. It consisted of two steel plates, one at the top, the other at the bottom, welded to the anchored steel plates in the column bracket and the beam. The design was later revised by adding side plates. Five specimens with such connections and two monolithic reference specimens were tested under reversed cyclic loading to study their behavior under seismic action. The main variables were the presence of side plates and the joint width. Based on the test results, it is concluded that side plates are essential for dry joints which are expected to be subjected to seismic action. It is also concluded that for such connections, joint width is an important parameter and, therefore, tolerances should be checked carefully during erection.
Children’s symbolic understanding of a digital, three-dimensional, interactive image (La comprensión simbólica infantil de una imagen digital, tridimensional e interactiva)

ABSTRACT Young children increasingly interact with technological devices, either as a form of entertainment or for educational purposes. This research sought to investigate the early symbolic understanding of an interactive, three-dimensional digital image presented on a tablet. Two studies were designed in which the children had to use the image as a source of information to solve a search task. The first study investigated the performance of children aged 30 and 36 months. We found that the children symbolically understood the image at 36 months, but not at 30. The second study investigated the impact of manipulation and instruction on the performance of 36-month-old children. The results showed that the manipulation of the image negatively impacted the understanding of it as a symbol, regardless of the instruction received. The results are interpreted in terms of the impact of manipulation, instruction and the three-dimensionality of the object on understanding it as a symbol. Possible implications in education are also discussed.
The Osteology of Shringasaurus indicus, an Archosauromorph from the Middle Triassic Denwa Formation, Satpura Gondwana Basin, Central India

ABSTRACT Archosauromorpha originated in the middle–late Permian and started to diversify in both non-marine and marine ecosystems dominating the world by the Triassic. The evolution of this group is poorly documented because the fossil record is limited. A detailed osteological description of Shringasaurus indicus, a non-archosaurian archosauromorph, from the Middle Triassic Satpura Basin, Central India, is provided here. The collection includes cranial bones, namely the nasal, frontals with and without horns, postfrontal, parietal, maxilla, premaxilla, quadrate, vomer, dentary, and braincase. The collection also comprises postcranial bones such as cervical, dorsal, sacral and caudal vertebrae, and girdle and limb bones. The phylogenetic study incorporates the character states from cranial as well as postcranial elements of Shringasaurus indicus. Furthermore, Malerisaurus robinsonae, another non-archosaurian archosauromorph from India, has been included in the phylogenetic analysis. The analysis reveals that both Shringasaurus indicus and Malerisaurus robinsonae are azendohsaurid allokotosaurs and Shringasaurus indicus is the sister taxon to both the species of Azendohsaurus. The detailed description of Shringasaurus indicus elucidates that the animal had a pair of supraorbital horns, was a large herbivore, and has an incongruous mixture of basal archosauromorph and dinosaurian-like character-states. Hence, the present study helps to fill the gap, to a large extent, in understanding the nature of the morphological diversity of basal archosauromorphs after the Permian–Triassic mass extinction.
