Thermal equation of state of omphacite

Abstract In-situ synchrotron X-ray diffraction experiments were conducted using the MAX-III multianvil press of KEK on an omphacite (Di63Jd37), for which Di = Ca(Mg,Fe)Si2O6 and Jd = NaAlSi2O6. Pressure-volume-temperature data were collected at up to 10 GPa and 1000 K. A fit to the hightemperature Birch-Murnaghan equation of state yielded an isothermal bulk modulus KT0 = 126(1) GPa, an assumed pressure derivative of the bulk modulus K'T = 4.0, a temperature derivative of the bulk modulus (∂KT/∂T)P = -0.015(4) GPa/K, and a volumetric thermal expansivity α = 2.2(1) × 10-5 K-1, when the equation of state of NaCl by Brown (1999) is adopted for the pressure scale. The derived KT0 value is consistent with the linear interpolations from KT0 values for diopside and jadeite in the literature.
Guidelines and Cost Analysis for Catalyst Production in Biocatalytic Processes

Biocatalysis is an emerging area of technology, and to date few reports have documented the economics of such processes. As it is a relatively new technology, many processes do not immediately fulfill the economic requirements for commercial operation. Hence, early-stage economic assessment could be a powerful tool to guide research and development activities in order to achieve commercial potential. This study discusses the cost contribution of the biocatalyst in processes that use isolated enzymes, immobilized enzymes, or whole cells to catalyze reactions leading to the production of chemicals. A methodology for rapidly estimating the production cost of the biocatalyst is presented, and examples of how the cost of the biocatalyst is affected by different parameters are given. In particular, it is seen that the fermentation yield in terms of final achievable cell concentration and expression level as well as the production scale are crucial for decreasing the total cost contribution of the biocatalyst.

Factors influencing acceptance of transgender athletes

ABSTRACT This study examined factors influencing acceptance of transgender athletes in sport events. Quantitative data were gathered from 373 Japanese university student-athletes. We investigated contributions of two types of predictors. One is the context in which trans athletes are placed; the other involves survey respondents’ psychological constructs that may influence their reaction to the issue. The results show that trans men were more accepted than trans women, trans athletes with hormone treatment were considered more acceptable, and trans athletes were more accepted in unofficial sporting events for children and adults than in official national and international events. The results also revealed that for respondents with weaker athletic identity, higher degrees of belief in a just world were positively associated with attitudes of acceptance. Whereas stronger athletic identity was positively associated with acceptance for men, it was negatively associated with acceptance for women. Considering the different nuances surrounding transgender issues in Japan, our study will add cultural diversity to research literature that has mainly focused on the contexts of North America and Western Europe. HIGHLIGHTS Trans athletes are accepted more in recreational sports than in elite competitions. Hormone treatment is one of the key elements determining acceptance. Athletic women are less likely to accept trans athletes than non-athletic women. Athletes with strong just belief are not accepting of trans athletes. Justice in sports is different from justice outside sports.
Effects of microbial inoculant and fibrolytic enzymes on fermentation quality and nutritional value of BRS capiaçu grass silage

The objective of this study was to evaluate the effect of bacterial-enzymatic inoculants with different concentrations of fibrolytic enzymes on the fermentation quality and nutritional value of the silage of BRS capiaçu grass. Two bacterial-enzymatic inoculants with different levels of enzyme complex were evaluated (Silotrato® (5%) and Biotrato® (8%)) and control silage (without additive) according to a completely randomized design with eight replicates. To evaluate the silage aerobic stability, a completely randomized split plot design was used with three treatments (plots) and seven times after opening (subplots). There was no interaction between treatments and times after opening on values of pH (P=0.79). Regarding bacterial-enzymatic inoculants, the silage pH was 21.66% and 16.16% higher in silage without additive (mean of 6.00) compared to silage with 5% and 8% enzyme complex (P < 0.01). There was no difference between treatments on pH (P = 0.08), lactic acid (p = 0.08) and acetic acid (p = 0.64), means of 3.11, 47.31 g dry matter (DM)-1 and 11.19 g DM-1, respectively. There was no difference between treatments for any of the chemical composition variables (P = 0.86). Mean values for DM, crude protein, neutral detergent fiber and total digestible nutrients were 22.31%, 6.65%, 71.15% and 42.07%, respectively. There was a higher concentration of butyric acid in the control silage compared to Silotrato® silage. The control silage and silage treated with Biotrato® presented effluent losses (P = 0.05) 13.99% higher than silage with Silotrato®. For ensiling BRS capiaçu grass, it is recommended to use lactic acid bacteria containing 5% fibrolytic enzymes.
INDOOR AIR QUALITY AND HEALTH IN NEWLY CONSTRUCTED APARTMENTS OF INDONESIA: CASE STUDY ON THE EFFECT OF MODIFICATION

In Indonesia, Sick Building Syndrome (SBS) and related health problems are suspected among the residents in emerging new urban houses constructed of modern building materials without sufficient material standards or minimum ventilation rates. First, this study investigates the current conditions of Indoor Air Quality (IAQ) and health in newly constructed high-rise apartments in major cities of Indonesia, in contrast with traditional landed houses, the so-called Kampongs. Concentrations of formaldehyde and TVOC were measured, whereas a face-to-face interview was conducted. A total of 896 respondents were interviewed, and 207 rooms were measured during 2017-2019. The results showed that overall, the newly constructed apartments recorded higher formaldehyde levels compared to Kampongs. The self-reported Multiple Chemical Sensitivity (MCS) status among occupants was significantly different between the two building types. Furthermore, the occupants with higher levels of TVOC, in particular, were associated with higher MCS risks, especially in the apartments. Second, we conducted a modification project in several apartment units of Surabaya to examine the effects of exhaust fans on IAQ. In most companies, the concentrations of both formaldehyde and TVOC were reduced after the modification. Further, a follow-up measurement was conducted in the same units for about a month.
Catalytic Fast Pyrolysis of Biomass Pretreated by Torrefaction with Varying Severity

Pretreatment of corncobs using torrefaction was performed in a tubular reactor with varying reaction temperature (210, 240, 270, or 300 °C) and residence time (20, 40, or 60 min). The torrefied corncobs were subsequently catalytically fast pyrolyzed over nanosized HZSM-5 in a semibatch pyroprobe reactor. The torrefied corncobs were characterized by elemental analysis, thermogravimetric analyzer coupled with Fourier transform infrared spectroscopy (FTIR), and FTIR. The aromatic production was online analyzed by gas chromatography mass spectroscopy. The effect of torrefaction severity on product distribution and aromatic selectivity from catalytic fast pyrolysis of torrefied corncobs was investigated. The experimental results show that torrefaction can serve as an effective thermal pretreatment for improving the selectivity of BTX (benzene, toluene, and xylenes). Light and mild torrefaction (torrefaction at 210 and 240 °C) has little impact on the aromatic yield. However, severe torrefaction (torrefaction a.
Molecular characterization of cherry virus a and prunus necrotic ringspot virus and their variability based on nucleotide polymorphism

Abstract A survey was conducted to know the incidence of viruses in apricot growing in the Srinagar and Shopian regions of Jammu and Kashmir during May 2015. A total of 52 leaf samples were obtained and virus infection was confirmed using nucleic acid spot hybridization (NASH) and reverse transcription-polymerase chain reaction (RT-PCR). The infectivity of cherry virus A (CVA) and prunus necrotic ringspot virus (PNRSV) was found to be 44% and 98% by NASH and 36% and 77% by RT-PCR, respectively. Based on the sequence variability of RdRp, CVA isolates found globally have been grouped into six phylogroups (Group 1–6), whereas PNRSV isolates from India have been divided into three phylogroups (Group 1, Group 2A and Group 2B) based on coat protein gene. Our findings prove that PNRSV and CVA are the two significant viruses of apricot, with PNRSV being the leading cause of apricot necrosis in old orchards.

Entrepreneurial learning behaviour of community insiders

PurposeThe purpose of the present paper is to explore entrepreneurial learning at the centre of communities of practice.Design/methodology/approachLearning perspectives from the community of practice concept are applied to interpret and discuss results from an in-depth empirical investigation using a novel qualitative method, the Zaltman metaphor elicitation technique (ZMET), to study the entrepreneurial learning behaviour of ten coaches in a student venture incubator. The coaches are students with a certain level of entrepreneurial experience. Given their coaching roles and practices, the coaches are considered “community insiders”. FindingsThe findings show how the socially situated entrepreneurial learning of community insiders could be considered an adaptive process following multiple learning trajectories depending on with whom and about what the entrepreneur involves in social relationships.Practical implicationsPolicy makers seeking to facilitate communities of practice should enable learning activities for community insiders and organic development in addition to networking events and support for the entire ecosystem in order to enable bridging of communities of practice.Originality/valueThe present paper focuses on the entrepreneurial learning of community insiders using a novel qualitative method, ZMET. The paper empirically demonstrates that community insiders learn through an adaptive process and participation in multiple communities of practice. This is both in interaction with the nascent entrepreneurs whom they coach as well as when interacting with other community insiders.
Recover to Discover the New Normal: A Case Study of Automotive Supply Chain Restoration after the COVID-19 Disruption

Under an onslaught of COVID-19, the automotive supply chain of a well-known manufacturer in Wuhan came to a screeching halt. We investigate the process of restarting a supply chain that had gone cold. There have been studies that looked at the process of ramping up new product lines, but to the best of our knowledge there have never been a study that looked at reviving a supply chain after a complete shutdown. We conduct an inductive case study involving a three-tier supply chain—the auto manufacturer, a China-Japan joint venture company, in the middle, with four suppliers to the upstream and four dealers to the downstream. Our analysis identifies four main contributing factors, workforce resilience, digital competence, supply chain rapport and government support, that have led to a successful recovery of the supply chain. The propositions developed from the analysis characterize the relative importance and complementarity of these factors, as well as their spillover effects to the new normal post recovery. These findings help enrich the existing theory of supply chain resilience by shining light on the importance of people and technology in supply chains, when recovering from a complete shutdown and discovering a new normal.
850-nm VCSEL-Based Single-Lane 200-Gbps PAM-4 Transmission for Datacenter Intra-Connections

A demonstration of an 850-nm vertical cavity surface emitting laser (VCSEL) based 200-Gb/s PAM-4 transmission over 100-m OM4 multimode fiber (MMF) is presented. To overcome the large Inter-symbol Interference (ISI) caused by bandwidth limitation and to compensate the non-linearity caused by optics, we propose to combine noise cancellation algorithm, partial response signaling and simplified Volterra nonlinear equalizer (NLE) in the digital signal processing (DSP). A power margin about 4 dB for 50-m MMF transmission and 3 dB for 100-m MMF transmission is observed. Different DSP configurations are also experimentally evaluated. The use of the simplified Volterra NLE enables the BER to be improved from <inline-formula> <tex-math notation="LaTeX">$2\times 10^{- {2}}$ </tex-math></inline-formula> to <inline-formula> <tex-math notation="LaTeX">$1.1\times 10^{- {3}}$ </tex-math></inline-formula>. A 2.5 dB power margin improvement is also achieved by employing the noise cancellation module.
Size‐based survival of cultured
 Argopecten purpuratus
 (L, 1819) under severe hypoxia

During recent years, mass mortalities of cultured scallops became more frequent in Peruvian bays. One of the main drivers related to these mortalities was hypoxic events. This study was designed to understand the hypoxia phenomenon in these bays and to assess how the Peruvian scallop, Argopecten purpuratus , can cope with reduced oxygen levels in seawater based on individual size. First, we analyzed the relationships between dissolved oxygen saturation and other environmental parameters (the Coastal El Niño Index, temperature, salinity and pH) in bottom seawater, the frequency and intensity of hypoxic events in two main culture areas (Sechura and Paracas Bays), and their relationship with scallop mass mortalities. Then, we performed experiments with two size groups of A. purpuratus (31 and 80 mm shell height; seed and commercial size, respectively) to assess their respective survival time under severe hypoxia (1% oxygen saturation) at 16 (cid:1) C and a salinity of 35. Finally, the results of the field records and the experimental data are used to suggest ways to improve scallop cultivation along the Peruvian coast.
Effect of Alcohol Solvents for Glycidyl Methacrylate in Radiation-Induced Graft Polymerization on Performance of Cation-Exchange Porous Membranes.

An epoxy-group-containing monomer, glycidyl methacrylate (GMA), was grafted onto a porous hollow-fiber membrane made of polyethylene, by radiation-induced graft polymerization. Four kinds of alcohol, i.e., methanol, ethanol, 1-propanol, and 1-butanol, were employed as the solvents for GMA. Grafting rate of GMA was decreased with increasing carbon number of alcohols. The epoxy group of the GMA-grafted membrane with a degree of grafting of 90 or 120% was converted to a sulfonic acid group at a molar conversion of 10 to 12%. Hen-egg lysozyme (HEL) dissolved in carbonate buffer solution (pH 9.0) was forced to permeate through the pores of the sulfonic-acid-group-containing porous hollow-fiber membranes prepared with various alcohol solvents. The binding capacity of HEL onto the membrane in equilibrium with the feed concentration of 0.5 g-HEL/L increased with the increase in the carbon number of alcohols. For example, the binding capacities of the membranes prepared with methanol and 1-butanol were 0.18 and 0.38 g-HEL/g-membrane, respectively. In contrast, the flux of the protein solution was decreased with increasing carbon number of alcohols. This demonstrates that longer polymer brushes are formed on the pore surface of the membrane prepared with a higher carbon number of alcohol employed as the solvent for GMA.
Climate Change Impact and Variability on Cereal Productivity among Smallholder Farmers under Future Production Systems in West Africa

Agriculture in West Africa is constrained by several yield-limiting factors, such as poor soil fertility, erratic rainfall distributions and low input systems. Projected changes in climate, thus, pose a threat since crop production is mainly rain-fed. The impact of climate change and its variation on the productivity of cereals in smallholder settings under future production systems in Navrongo, Ghana and Nioro du Rip, Senegal was assessed in this study. Data on management practices obtained from household surveys and projected agricultural development pathways (through stakeholder engagements), soil data, weather data (historical: 1980–2009 and five General Circulation Models; mid-century time slice 2040–2069 for two Representative Concentration Pathways; 4.5 and 8.5) were used for the impact assessment, employing a crop simulation model. Ensemble maize yield changes under the sustainable agricultural development pathway (SDP) were −13 and −16%, while under the unsustainable development pathway (USDP), yield changes were −19 and −20% in Navrongo and Nioro du Rip, respectively. The impact on sorghum and millet were lower than that on maize. Variations in climate change impact among smallholders were high with relative standard deviations (RSD) of between 14% and 60% across the cereals with variability being higher under the USDP, except for millet. Agricultural production systems with higher intensification but with less emphasis on soil conservation (USDP) will be more negatively impacted by climate change compared to relatively sustainable ones (SDP).
Something Old, Something New, Something Borrowed and Something Blue about NIR

Introduction T he traditional rhyme “Something old, something new, something borrowed and something blue” details what a bride should wear at her wedding for good luck. In the same way, it can illustrate the fundamental or prior knowledge to take in consideration when an application based on NIR spectroscopy is developed not only to measure chemical composition for quality control in an industrial setting but also as a modern and versatile technique. Most of these fundamentals or critical steps are related to the so called “optical properties” of the sample (“something old”). Among these properties, light absorption and scattering, geometry properties related to sample presentation (transmission vs reflectance; homogenised vs intact) and surface roughness are the most important ones affecting the optical properties of fresh agricultural products such as meat, fruits and vegetables. When NIR analysis is carried out, the main players involved during the analysis are the instrument, the sample and the user. However, most of the time, too much effort is devoted to the chemometrics (“something borrowed”) or calibration development. Ian Murray in 1999 stated that “we still cannot be sure of what may or may not predicted by an NIR calibration—the model is not what is important—rather the interferences which come from it”. Understanding these interferences is of fundamental importance in order to develop a successful NIR application. Optical geometries, absorption and scattering Different properties or characteristics can drive the interactions between light and matter; among them, geometry and absorption may be mentioned. Geometry is related to relationships between the sample and the instrument (e.g. sample presentation) and the physical interactions which are affected by the dimensions of matter and the wavelength radiation to which matter is subjected while absorption is related to the radiation (light or energy) absorbed. Radiation is absorbed in discrete amounts or quanta (photons) and the absorbing molecules are excited to specific vibrational states, depending on the levels of exciting radiation. Light scattering is the process of radiation being redistributed inside a material and is largely a function of two main factors. The first is related to the distance between the sample and the optical interfaces, while the second is associated with the refractive index of the sample. Thus, scattering is one of the most important factors in diffuse reflectance of fresh samples such as meat, fruit, vegetables and other products that have high moisture contents. Figure 1 illustrates how geometry, absorption and scattering affect the measurements of total anthocyanins in red grapes. The coefficients of variation (CV ) obtained for the measurement of total anthocyanins can vary between 25% and 47%.
A 0.7-1.5GHz Tunable Papoulis All-Pole Low-Pass Filter in 22nm CMOS FDSOI

A tunable 10-stage all-pole (Papoulis) low-pass filter occupying 0.1815mm2 is designed and integrated as a building block in a 22nm CMOS FDSOI receiver for the 5G. Each filter stage comprises of a two-stage unity gain buffer with common mode feedback loop. Tunable resistors between each stage determine the bandwidth of the filter in the range of 0.7 GHz to 1.5 GHz. An identical filter structure, but with the outputs fed back to the inputs functions as an oscillator. Correlating the oscillation frequency with the filter bandwidth, under the same tuning conditions, the filter bandwidth can be calibrated to account for PVT variations. Measurement results show an in-band OIP3 of 8.8dBm and a nearly linear phase response at a power consumption of 35mW to 50mW from a 1V supply. The power/pole of 3.3mW/GHz is the best when compared to other filters from literature.
