Improving heat transfer coefficient during double-sided meat frying

Improving the energy efficiency of technological processes and equipment for heat treatment of meat and meat products is a relevant scientific task. A prerequisite for the development of new energy and resource-saving equipment for frying meat is the study of the mechanism of heat transfer in the surface layers of the product. The aim of the work was to determine the effect of the value of the logarithmic mean temperature difference (LMTD) on the value of the heat transfer coefficient k during ouble-sided frying of organic meat products by the physical and electrophysical methods. The study has proved that the LMTD between the frying surface temperature and the temperature of liquid on the capillary meniscus surface depend on the frying surface temperature. An increase in the frying surface temperature from 393 K to 423 K reduces the LMTD between the frying surface temperature and the temperature of liquid on the meniscus surface from 10 K to 6 K. The specified method of calculating the coefficient of heat transfer through vapor layers takes into account the change in the contact area of the meniscus liquid with the frying surface during evaporation and the area of the meniscus surface in the vapor condensation during double-sided frying of pork under pressure. The study has proved the dependence of the heat transfer coefficient on the LMTD between the temperature of the frying surface and the temperature of liquid on the meniscus surface. The calculated actual coefficient of heat transfer from the frying surface to the product is k 423 =3800 W/(m 2 K) for the LMTD =10 K and k 393 =3800 W/(m 2 K) at K. The theoretically substantiated duration of double-sided frying of organic meat under compression is completely identical to the real one.
The new approach minimizes harmonics in a single-phase three-level NPC 400 Hz converter for airplanes

This paper provides a new approach to reducing high-order harmonics in 400 Hz inverter using a three-level neutral-point clamped (NPC) converter. A voltage control loop using the harmonic compensation combined with NPC clamping diode control technology. The capacitor voltage imbalance also causes harmonics in the output voltage. For 400 Hz inverter, maintain a balanced voltage between the two input (direct current) (DC) capacitors is difficult because the pulse width modulation (PWM) modulation frequency ratio is low compared to the frequency of the output voltage. A method of determining the current flowing into the capacitor to control the voltage on the two balanced capacitors to ensure fast response reversal is also given in this paper. The combination of a high-harmonic resonator controller and a neutral-point voltage controller working together on the 400 Hz NPC inverter structure is given in this paper.
Mechanically Reconfigurable, Beam-Scanning Reflectarray and Transmitarray Antennas: A Review

We review mechanically reconfigurable reflectarray (RA) and transmitarray (TA) antennas. We categorize the proposed approaches into three major groups followed by a hybrid category that is made up of a combination of the three major approaches. We discuss the examples in each category and compare their performance metrics including aperture efficiency, gain, bandwidth and scanning range and resolution. We also identify opportunities to build upon or extend these demonstrated approaches to realize further advances in antenna performance.
A Pilot Study of Ponatinib in Patients With FGFR-Altered Advanced Cholangiocarcinoma

Background:Biliary tract cancers (BTC) are rare, chemo resistant and are associated with a poor prognosis. Preclinical and early clinical work had demonstrated interesting anti-tumor activity from targeting fibroblast growth factor receptor (FGFR) pathway. We hypothesized that ponatinib, a multi-targeted tyrosine kinase inhibitor with activity against FGFR, would be active in BTC patients with FGFR alterations.Methods:This was a multi-center, single institution pilot study of ponatinib in patients with advanced, refractory BTC with FGFR alterations. The primary end point was overall response rate, with secondary points of overall survival (OS), progression-free survival (PFS) and Health Related Quality of Life (HRQoL) assessment. Results:Twelve patients were enrolled prior to early termination of the trial. Clinical benefit (defined as complete/partial response + stable disease) of 45.5% was observed. All observed toxicities were manageable and reversible. Toxicities were mild, with lymphopenia (75%), rash (63%) and fatigue (50%) being the most frequent. No significant detriment in global QoL was observed.Conclusions:Ponatinib as a single agent in FGFR altered BTC is tolerable with very modest clinical activity. This is the first report of prospective assessment of FGFR inhibition in BTC using ponatinib, and the first study to report its effect on HRQoL. Further development of ponatinib will involve correlative studies to better refine patient selection, focus on combinations with other molecular targeted agents, conventional cytotoxic chemotherapy, and studies to better understand mechanisms of treatment resistance.
A framework for predicting employee health risks using ensemble model

Through the phenomenon of data, big data and data analytics have provided an opportunity to collect, store, process, analyze and visualize an immense amount of information. Healthcare is recognized as one of the most information-intensive sectors. An urge to explore analytics has been sparked by the rapid growth of data within the healthcare sector. Most employers in Malaysia provide medical benefits that are included in the medical insurance plan for their employees. Data collected such as the history of medical claims are stored with the HR (Human Resource) which contributes to the potential of analyzing and recognizing trends within medical claims to better understand the use and overall health of the employee population. Patients with higher risk will generally convert into patients with high costs. Hence, early intervention of these patients will allow employers to potentially minimize costs and plan preventative steps. In predictive analysis, Decision Trees and Regression are typical techniques applied. The proposed framework combines an ensemble technique known as Stacking. As opposed to a single predictive model, an ensemble predictive model would yield better performance and accuracy. The objective of this paper is therefore to review current practices and past research within the healthcare sector while suggesting a practical framework for classification ensemble modeling. Preliminary findings indicated that an ensemble model can produce higher predictive accuracy and performance than a single model.
Antimicrobial Activity of Se-Nanoparticles from Bacterial Biotransformation

Selenium nanoparticles (SeNPs) are gaining importance in the food and medical fields due to their antibacterial properties. The microbial inhibition of these kinds of particles has been tested in a wide range of Gram (+) and Gram (−) pathogenic bacteria. When SeNPs are synthesized by biological methods, they are called biogenic SeNPs, which have a negative charge caused by their interaction between surface and capping layer (bioorganic material), producing their high stability. This review is focused on SeNPs synthesis by bacteria and summarizes the main factors that influence their main characteristics: shape, size and surface charge, considering the bacteria growth conditions for their synthesis. The different mechanisms of antimicrobial activity are revised, and this review describes several biosynthesis hypotheses that have been proposed due to the fact that the biological mechanism of SeNP synthesis is not fully known.
Shallow Crustal Shear Velocity and Vp/Vs Across Southern California: Joint Inversion of Short‐Period Rayleigh Wave Ellipticity, Phase Velocity, and Teleseismic Receiver Functions

Near‐surface seismic velocity structure plays a critical role in ground motion amplification during large earthquakes. In particular, the local Vp/Vs ratio strongly influences the amplitude of Rayleigh waves. Previous studies have separately imaged 3D seismic velocity and Vp/Vs ratio at seismogenic depth, but lack regional coverage and/or fail to constrain the shallowest structure. Here, we combine three datasets with complementary sensitivity in a Bayesian joint inversion for shallow crustal shear velocity and near‐surface Vp/Vs ratio across Southern California. Receiver functions–including with an apparent delayed initial peak in sedimentary basins, and long considered a nuisance in receiver function imaging studies–highly correlate with short‐period Rayleigh wave ellipticity measurements and require the inclusion of a Vp/Vs parameter. The updated model includes near‐surface low shear velocity more in line with geotechnical layer estimates, and generally lower than expected Vp/Vs outside the basins suggesting widespread shallow fracturing and/or groundwater undersaturation.
A DATA-DRIVEN APPROACH TO USER-EXPERIENCE-FOCUSED MODEL-BASED ROADMAPPING FOR NEW PRODUCT PLANNING

Abstract User experience (UX) focused business needs to survive and plan its new product development (NPD) activities in a highly turbulent environment. The latter is a function of volatile UX and technology trends, competition, unpredictable events, and user needs uncertainty. To address this problem, the concept of design roadmapping has been proposed in the literature. It was argued that tools built on the idea of design roadmapping have to be very flexible and data-driven (i.e., be able to receive feedback from users in an iterative manner). At the same time, a model-based approach to roadmapping has emerged, promising to achieve such flexibility. In this work, we propose to incorporate design roadmapping to model-based roadmapping and integrate it with various user testing approaches into a single tool to support a flexible data-driven NPD planning process.
Inertial Accelerated Algorithm for Fixed Point of Asymptotically Nonexpansive Mapping in Real Uniformly Convex Banach Spaces

In this work, we introduce a new inertial accelerated Mann algorithm for finding a point in the set of fixed points of asymptotically nonexpansive mapping in a real uniformly convex Banach space. We also establish weak and strong convergence theorems of the scheme. Finally, we give a numerical experiment to validate the performance of our algorithm and compare with some existing methods. Our results generalize and improve some recent results in the literature.
Complete Chloroplast Genome Sequence of Fortunella venosa (Champ. ex Benth.) C.C.Huang (Rutaceae): Comparative Analysis, Phylogenetic Relationships, and Robust Support for Its Status as an Independent Species

Fortunella venosa (Rutaceae) is an endangered species endemic to China and its taxonomic status has been controversial. The genus Fortunella contains a variety of important economic plants with high value in food, medicine, and ornamental. However, the placement of Genus Fortunella into Genus Citrus has led to controversy on its taxonomy and Systematics. In this present research, the Chloroplast genome of F. venosa was sequenced using the second-generation sequencing, and its structure and phylogenetic relationship analyzed. The results showed that the Chloroplast genome size of F. venosa was 160,265 bp, with a typical angiosperm four-part ring structure containing a large single copy region (LSC) (87,597 bp), a small single copy region (SSC) (18,732 bp), and a pair of inverted repeat regions (IRa\IRb) (26,968 bp each). There are 134 predicted genes in Chloroplast genome, including 89 protein-coding genes, 8 rRNAs, and 37 tRNAs. The GC-content of the whole Chloroplast genome was 43%, with the IR regions having a higher GC content than the LSC and the SSC regions. There were no rearrangements present in the Chloroplast genome; however, the IR regions showed obvious contraction and expansion. A total of 108 simple sequence repeats (SSRs) were present in the entire chloroplast genome and the nucleotide polymorphism was high in LSC and SSC. In addition, there is a preference for codon usage with the non-coding regions being more conserved than the coding regions. Phylogenetic analysis showed that species of Fortunella are nested in the genus of Citrus and the independent species status of F. venosa is supported robustly, which is significantly different from F. japonica. These findings will help in the development of DNA barcodes that can be useful in the study of the systematics and evolution of the genus Fortunella and the family Rutaceae.
Differences in Soil Physicochemical Properties in Different-Aged Pinus massoniana Plantations in Southwest China

With increasing age, plants will cause changes in soil physicochemical properties. The objective of this study was to investigate differences in the soil physicochemical properties in different-aged Masson pine forest plantations (i.e., 10, 20, 40, and 60 years old). Soil samples were collected in a pure Masson pine forest plantation in Southwest China. The soil determination indexes included organic carbon, nitrogen, phosphorus and potassium contents, water content, bulk density, and pH. The soil pH of a 20-year-old forest was significantly (p < 0.05) higher than that of a 10, 40, and 60-year-old forest. In addition, soil-available phosphorus in a 60-year-old forest was significantly (p < 0.05) higher than that in the other three age forest groups. With increasing forest age, available phosphorus increased, while available nitrogen decreased at 20 years old and then increased at 40 years old. There was a significant positive correlation (p < 0.05) between total nitrogen and available potassium; no significant correlation (p> 0.05) between total phosphorus and total potassium, organic carbon, bulk density, and pH; and a significant negative correlation (p < 0.05) between available phosphorus and the water content. The availability and utilization efficiency of soil nutrients in young forests were higher than those in old forests and the intermediate forest age was an important time point that affected the soil properties. To improve the availability of soil nutrients and ensure the sustainable utilization of soil resources, it is necessary to increase the input of nitrogen and especially phosphorus. More attention should be given to the phytochemometric response with respect to the age of plantations.
Factor Endowments, Economic Integration, Round-Tripping, and Inward FDI: Evidence from the Baltic Economies

This paper studies the location choice of foreign multinational firms in the Baltic economies of Estonia, Latvia, and Lithuania using a knowledge-and-physical capital model across 2004–2017. We used the Bayesian model averaging estimation method to investigate a set of possible factors that drive inward FDI. Our analysis demonstrates that factor endowments play a dominant role in driving vertical foreign direct investment, while external market barriers generate “tariff-jumping” FDI. Our analysis quantifies the effects of round-trip FDI, European integration, and external bilateral free trade agreements vis-à-vis inward FDI in the Baltics.
Fluctuation-induced magnetic phase transitions in Fe and MnSi studied by neutron scattering

This thesis reports on the phase transition from the paramagnetic to the ferromagnetic phase in bcc-iron, and from the paramagnetic to the helimagnetic phase in the cubic helimagnet MnSi. In MnSi, the effects of a magnetic field and substitutional doping on the phase transition were investigated. To facilitate the experiments, the MIEZE setup at the instrument RESEDA has been enhanced towards a larger dynamic range and augmented with the possibility to investigate samples under extreme conditions.
Effect of Community-Level Intervention on Early Initiation and Optimal Antenatal Care Attendance: A Quasi-Experimental Study Among Post-Partum Women in Eastern Uganda

Background: Initiating antenatal care within the first trimester and making at least four visits during pregnancy are recommended to enable screening and support for healthy lifestyles, well-being, and self-care in pregnancy. Due to glaring evidence on inequalities in access to antenatal care, this study assessed the effect of engaging community health structures on utilization of antenatal care services during pregnancy in resource-constrained rural settings in Uganda. Methods: A quasi-experimental evaluation study was conducted among mothers in Eastern Uganda. The intervention components included community dialogues and empowering community health workers to sensitize expectant mothers on the use of maternal health services, and health facility strengthening. The primary outcomes were early initiation of antenatal care and completion of at least 4 ANC visits. We used Difference in Differences (DiD) analysis and multivariate regression to assess the effect of the intervention on ANC attendance.Results: Early initiation of antenatal care increased from 35.7% to 48.1% in the intervention area and 26.9% to 40.7% in the control area but with a non-significant net change of -1.3% (DID, p = 0.733) in the intervention area with respect to changes in the control area. The DiD results revealed the intervention resulted in a 5.5% net significant improvement in attendance of at least 4 ANC visits (p= 0.037). Higher education level of husband (PR1.19,95%CI 1.02–1.39), higher household size (PR=0.81, 95%CI 0.70–0.95), and higher wealth index (PR1.19,95%CI 1.03–1.37) predicted early initiation. Making at least 4 visits for antenatal care was influenced by post-primary education (PR1.14, 95%CI 1.02–1.30), higher wealth quintile (PR1.17, 95%CI 1.06 – 1.30), early initiation (PR1.58, 95%CI 1.49–1.68), and the community intervention (PR1.16, 95%CI 1.01–1.33). Conclusion: Although the community intervention improved the attendance of at least four antenatal care visits, effect estimates are low hence raising scepticisms on the feasibility of at least 8 visits as per the new WHO recommendations. Women with less education should be prioritized in maternal and child health (MCH) interventions as their families need economic empowerment to reduce financial barriers when access MCH services.
Multiwavelength observations reveal a faint candidate black hole X-ray binary in IGR J17285−2922

IGR J17285−2922 is a known X-ray binary with a low peak 2–10 keV X-ray luminosity of ∼ 1036 erg s−1 during outburst. IGR J17285−2922 exhibited two outbursts in 2003 and 2010 and went into outburst again in 2019. We have monitored this ∼ 4-month long 2019 outburst with Swift in X-ray and the Very Large Array in radio. We have also obtained four optical spectra with the Gran Telescopio Canarias and Southern Astrophysical Research Telescope, three optical photometry measurements with the Las Cumbres Observatory, and one near-infrared spectrum with the Gemini South telescope. The ratio between its X-ray and radio luminosity is consistent with both samples of neutron star and black hole (BH) X-ray binaries, while the ratio between the X-ray and optical luminosity is consistent with BH X-ray binaries. Studying the evolution of its X-ray power-law index throughout the outburst, we find additional evidence for a BH as compact object. The four optical spectra show no H α emission and the nIR spectrum shows no Brγ emission, suggesting that the donor star could be hydrogen-poor and hence that IGR J17285−2922 might have an ultracompact binary orbit. The shape of the X-ray light curve is well described by an exponential, followed by a linear decay, from which we obtain a relation between the orbital period Porb and the binary mass ratio. We discuss how this relation is consistent with theoretical predictions and known ultracompact X-ray binaries. Lastly, we discuss how the observed properties are reminiscent of short-Porb BH X-ray binaries.
Development and validation of UV spectrophotometric methods for simultaneousestimation of Paracetamol and Ibuprofen in pure and tablet dosage form

Two simple, rapid, accurate, precise, and economic spectrophotometric methods for simultaneous estimation of paracetamol and ibuprofen in pure and tablet dosage form have been developed. Method I is based on solving simultaneous equation. Paracetamol and ibuprofen show absorbance maximums at 256 and 222.4 nm respectively, so absorbance was measured at the same wave lengths for the estimation of paracetamol and ibuprofen. Method II is based on determination of Q-value. Absorbance is measured at 226.4 nm (Isoabsorptive point) and 222.4nm (λmax of ibuprofen). Both drugs obey the Beer Lambert's law in the concentration range of 5-30 μg/mL. Methods are validated according to ICH guidelines and can be adopted for the routine analysis of paracetamol and ibuprofen in pure and tablet dosage form.
Status Threat, Social Concerns, and Conservative Media: A Look at White America and the Alt-Right

Racial and ethnic division is a mainstay of the American social structure, and today these strains are exacerbated by political binaries. Moreover, the media has become increasingly polarized whereby certain media outlets intensify perceived differences between racial and ethnic groups, political alignments, and religious affiliations. Using data from a recent psychological study of the Alt-Right, we assess the associations between perceptions of social issues, feelings of status threat, trust in conservative media, and affiliation with the Alt-Right among White Americans. We find concern over more conservative social issues along with trust in conservative media explain a large portion of the variation in feelings of status threat among White Americans. Furthermore, more conservative social issues plus feeling of status threat significantly increase the odds of Alt-Right affiliation. Most surprisingly, however, trust in conservative media mitigated, instead of amplified, these associations. Implications and calls for future research are discussed.
