Published: January 2022

The halal food industry is no longer underrated. Since consumers became very concerned about their daily consumption considering the hygiene that should be maintained. This research was aimed to measure the Indonesian consumers’ willingness to buy halal food, especially meat products, based on trust, awareness, packaging information, and food safety. However, Indonesian consumers’ demand for halal food is not proportional comparing to a large number of the Muslim population. Contrast to previous similar studies that adopting the Theory of Planned Behavior (TPB) or Theory of Reasoned Action (TRA) that focused more on halal awareness and halal labels, this study was adopting Hedonic Theory. This research using 186 data that were collected by online questionnaires. Data then analyzed using multiple linear regression and Ordinal Least Square (OLS). Results showed that only halal awareness and food safety are proven to have significant positive effects on willingness to buy. Regardless of Muslim and non-Muslim, halal awareness and food safety attract consumers’ willingness to buy halal-labeled meat products. To increase the willingness to buy halal meat products in Indonesia, the government and producers must be able to encourage awareness of the importance of eating halal food. Furthermore, they also must ensure the safety of that food. Hopefully, these findings can become input for stakeholders.

Published: January 2022

The calculation of beta stock in Indonesia is still debatable to this day. Though many researchers who have used sophisticated methods mathematically, the assumptions applied in developing the methods are impossible to happen in the real world, such as the ability of stock market return the day after (lead) affects the market return today. This study was conducted to assess the stock price index in Indonesia Stock Exchange that can be used as a proxy of stock market in Indonesia. The results of this study showed that there was a gap between beta stocks counted with JCI return as a market proxy with beta stocks counted with index returns of LQ-45, SRI-KEHATI, PEFINDO-25, BISNIS-27, IDX-30 and KOMPAS-100. This study has also found that the beta counted by using KOMPAS-100 return produced the smallest standard error of the estimate (SEE) that it was more applicable compared to the other stock index returns.

Published: January 2022

This study aims to examine the marketing efficiency of processed melinjo in women's farmer groups with data collected in Batang Regency, Central Java. Emping melinjo has contributed to providing additional work for mothers as a side business. The method used in this research is a survey of KWT Tani Rejo. Melinjo emping producer data was collected by purposive (deliberate) and traders' samples were done by snowball sampling and respondents were taken by census on all members of KWT Tani Rejo. The data obtained were analyzed descriptively and calculated using margin analysis and farmer share. The results show that the first channel of emping melinjo marketing is the most efficient than the second and third channels. Producers accept higher prices and do not bear marketing costs, because they sell directly to consumers. Meanwhile, marketing efficiency on channels 2 and 3 is greater than 30%. Margins on channels 2 and 3 reached 40% and 16% respectively. Marketing actors include producers, collectors, wholesalers, agents, and retailers. The involvement of women in this business group is due to limited costs and access to market information.
Starting and Subsequent Earnings of Young Workers in Different Sized Firms
Authors: Tannen Michael
Published: January 2022

Based upon the highly innovative Project TALENT Longitudinal Database, this study tracks the starting earnings and subsequent early earnings growth of young males who began their work careers at either a smaller (<100 employees) or larger private firm more than a generation ago.  Prior evidence based upon less rich databases found that earnings were systematically higher in larger firms but did not have access to many other variables that could affect projected earnings which are available in the TALENT database. Earnings regressions are estimated here including not only usual explanatory variables of years of schooling and labor market experience, but also adding other variables pertaining to prior job experience, military service, IQ, socioeconomic background and some other factors.  The findings indicate that while starting earnings of those in this database were indeed higher in larger firms, the gap evaporated fairly quickly with projected earnings of those in smaller firms featuring a small earnings premium. The results here suggest guidance based upon the body of prior evidence may have been less reliable than thought, and that evidence itself may not provide as useful a baseline as desired for subsequent research addressing whether this pattern continues for recent cohorts.

How the Telegraph and the Telephone Formed a Worldwide Wired Electromagnetic Environment
Authors: Ian Baldwin M. A.
Published: January 2022

The principle of electromagnetic induction was independently discovered by Michael Faraday (England) and Joseph Henry (USA) in 1831–32. The momentous discovery gave birth to numerous inventions that made civilization “modern,” beginning with the telegraph. First the telegraph and then the telephone required the installation of millions of miles of electric wire to cross continents and oceans in order to function as a global telecommunications system. These wires created a wholly new, anthropogenic electromagnetic environment, whose frequencies were orders of magnitude greater than those occurring naturally. Its effects on human beings, particularly inside cities, and the biosphere generally were unknown. Even now, more than a century later, the medical and environmental effects of this worldwide wired infrastructure are at best but partially understood. The telecommunications revolutions of the mid- and late 19th century were eagerly anticipated and implemented swiftly on an unprecedented scale, creating the technological basis for worldwide instantaneous communication. This paper describes the key discoveries that created the scientific and technical breakthroughs that allowed the first telecommunications revolutions to take place.
Application of RtcB ligase to monitor self-cleaving ribozyme activity by RNA-seq
Authors: Olzog V. Janett , Freist Lena I. , Goldmann Robin , Fallmann Jörg , Weinberg Christina E.
Published: January 2022

Self-cleaving ribozymes are catalytic RNAs and can be found in all domains of life. They catalyze a site-specific cleavage that results in a 5′ fragment with a 2′,3′ cyclic phosphate (2′,3′ cP) and a 3′ fragment with a 5′ hydroxyl (5′ OH) end. Recently, several strategies to enrich self-cleaving ribozymes by targeted biochemical methods have been introduced by us and others. Here, we develop an alternative strategy in which 5ʹ OH RNAs are specifically ligated by RtcB ligase, which first guanylates the 3′ phosphate of the adapter and then ligates it directly to RNAs with 5′ OH ends. Our results demonstrate that adapter ligation to highly structured ribozyme fragments is much more efficient using the thermostable RtcB ligase from Pyrococcus horikoshii than the broadly applied Escherichia coli enzyme. Moreover, we investigated DNA, RNA and modified RNA adapters for their suitability in RtcB ligation reactions. We used the optimized RtcB-mediated ligation to produce RNA-seq libraries and captured a spiked 3ʹ twister ribozyme fragment from E. coli total RNA. This RNA-seq-based method is applicable to detect ribozyme fragments as well as other cellular RNAs with 5ʹ OH termini from total RNA.

Thereupon it is explained to what an extent the perception of this crisis has increased in statements by the Roman Catholic and Lutheran Churches. How the ecological crisis is mirrored in substantial practical theological publications is demonstrated in an overview on the basis of three pertinent monographs on religious education. Then the focus lies on the resulting task of Education for Sustainable Development and on the question of its potential religious contours. Furthermore, relevant empirical studies on ecological awareness and education are presented.
Allelic dropout in PAH affecting the results of genetic diagnosis in phenylketonuria
Authors: Wang Lin , He Bin , Jin Qiujie , Bai Ruimiao , Yu Wenwen , Qiang Rong , Wang Xiaobin
Published: January 2022

Objectives

Phenylketonuria (PKU) is an inherited autosomal recessive disorder of phenylalanine metabolism. It is mainly caused by a deficiency in phenylalanine hydroxylase (PAH) and frequently diagnosed with Sanger sequencing. To some extent, allelic dropout can explain the inconsistency in genotype and phenotype.

Methods

Three families were evaluated through DNA sequence analysis, multiplex ligation-dependent probe amplification (MLPA) and prenatal diagnosis technologies. The possibility of inconsistency in phenotype and genotype with c.331C>T variant was analysed.

Results

Through pedigree analysis, three mothers carried a homozygous c.331C>T variant, which was a false-positive result. New primers were used, and this error was caused by allelic dropout. In this case, c.158G>A was likely a benign variant.

Conclusions

Sequence variants in primer-binding regions could cause allelic dropout, creating unpredictable errors in genotyping. Our results emphasised the need for careful measures to treat genotype–phenotype inconsistencies.

Published: January 2022

In this study, the pool boiling performance of oxide nanofluid was investigated, the heating surface is a 5 × 30 mm stainless steel heating surface. Three kinds of nanofluids were selected to explore their critical heat flux (CHF) and heat transfer coefficient (HTC), which were TiO2, SiO2, Al2O3. We observed that these nanofluids enhanced CHF compared to R·O water, and Al2O3 case has the most significant enhancement (up to 66.7%), furthermore, the HTC was also enhanced. The number of bubbles in nanofluid case was relatively less than that in R·O water case, but the bubbles were much larger. The heating surface was characterized and it was found that there were nano-particles deposited, and surface roughness decreased. The wettability also decreased with the increase in CHF.

Two novel zinc(II) complexes containing 4-methoxybenzylidene moieties namely, Zn(L)Cl2 (L = N, N′-bis(4-methoxybenzylidene)ethane-1, 2-diamine (1) or N-(4-methoxybenzylidene)-ethane-1, 2-diamine (2)) have been synthesized and characterized by infrared spectroscopy and single-crystal X-ray diffraction. Complex 1 crystallizes in the monoclinic space group P21/c with a = 9.2315(4); b = 12.0449(4); c = 18.2164(7) Å; β = 98.472(4)°, V = 1278.9(4) Å3 and Z = 4. Complex 2 crystallizes in the monoclinic space group P21/n with a = 6.5733 (2), b = 13.6595(5), c = 15.1615(5) Å; β = 101.846(4)°, V = 1332.33(8) Å3 and Z = 4. The environment of each Zn(II) atom is distorted tetrahedral with coordination of two terminal Cl atoms and two N atoms of the N,N′ – bis(4-methoxybenzylidene)ethane-1,2-diamine (1) or N-(4-methoxybenzylidene)ethane-1,2-diamine (2) ligand. The stability of the crystalline structure is ensured by the existence of intra- and intermolecular hydrogen bonds of the type C–H…Cl (1) and N–H…Cl (2) leading to supramolecular topologies.

Lopes dos Santos, M, Mann, JB, Berton, R, Alvar, B, Lockie, RG, and Dawes, JJ. Using the load-velocity profile for predicting the 1RM of the hexagonal barbell deadlift exercise. J Strength Cond Res 37(1): 220–223, 2023—The aim of this study was to determine whether bar velocity can be used to estimate the 1 repetition maximum (1RM) on the hexagonal bar deadlift (HBD). Twenty-two National Collegiate Athletic Association Division I male ice hockey players (age = 21.0 ± 1.5 years, height = 182.9 ± 7.3 cm, and body mass = 86.2 ± 7.3 kg) completed a progressive loading test using the HBD at maximum intended velocity to determine their 1RM. The mean concentric velocity was measured for each load through a linear position transducer. The a priori alpha level of significance was set at p = 0.05. The mean concentric velocity showed a very strong relationship to %1RM (R
2 = 0.85). A nonsignificant difference and a trivial effect size (ES) were observed between the actual and predicted 1RM (p = 0.90, ES = −0.08). Near-perfect correlations were also discovered between the actual and predicted 1RM (R = 0.93) with low typical error and coefficient of variation (5.11 kg and 2.53%, respectively). This study presented results that add the HBD to the list of exercises with established load-velocity relationships. The predictive ability for 1RM HBD indicates that this is a viable means of prediction of 1RM.
TRPV1-Lineage Somatosensory Fibers Communicate with Taste Neurons in the Mouse Parabrachial Nucleus
Authors: Li Jinrong , Ali Md Sams Sazzad , Lemon Christian H.
Published: January 2022

Trigeminal neurons convey somatosensory information from craniofacial tissues. In mouse brain, ascending projections from medullary trigeminal neurons arrive at taste neurons in the parabrachial (PB) nucleus, suggesting that taste neurons participate in somatosensory processing. However, the cell types that support this convergence were undefined. Using Cre-directed optogenetics andin vivoneurophysiology in anesthetized mice of both sexes, here we studied whether transient receptor potential vanilloid 1 (TRPV1)-lineage nociceptive and thermosensory fibers are primary neurons that drive trigeminal circuits reaching PB taste cells. We monitored spiking activity in individual PB neurons during photoexcitation of the terminals of TRPV1-lineage fibers arriving at the dorsal trigeminal nucleus caudalis, which relays orofacial somatosensory messages to the PB area. We also recorded PB neural responses to oral delivery of taste, chemesthetic, and thermal stimuli. We found that optical excitation of TRPV1-lineage fibers elicited responses in traditionally defined taste neurons in lateral PB nuclei. The tuning of neurons across diverse tastes associated with their sensitivity to TRPV1-lineage fiber stimulation, which only sparingly engaged neurons oriented to preferred tastes like sucrose. Moreover, neurons responsive to photostimulation of TRPV1-lineage afferents showed strong responses to temperature including noxious heat, which predominantly excited PB bitter taste cells. Multivariate and machine learning analyses revealed the PB confluence of TRPV1-lineage signals with taste captured sensory valence information shared across aversive gustatory, nociceptive, and thermal stimuli. Our results reveal that TRPV1-lineage fibers, which have defined roles in thermosensation and pain, communicate with PB taste neurons. This multisensory convergence supports dependencies between gustatory and somatosensory hedonic representations in the brain.

SIGNIFICANCE STATEMENTThe parabrachial (PB) nucleus participates in autonomic and integrative neural processing for diverse sensory modalities. We recently found in mice that trigeminal neurons supplying craniofacial somatosensation project to PB neurons sensitive to tastes. Here, we show that trigeminal projections to PB gustatory cells are driven by a genetic class of thermosensory and nociceptive fiber. Input from these fibers was associated with PB neural sensitivity to aversive oral temperatures and tastes and supported a multimodal neural representation of sensory valence across gustatory, nociceptive, and thermal stimuli. These results reveal gustation and somatosensation to be only components of a larger PB code that captures sensory value. Defining this circuit has implications for understanding the neural representation of taste, temperature, and also pain-related phenomena.

A number of methods have been applied to measure total antioxidant capacity (TAC), including FRAP, which is based on reducing the amount of iron ions in a complex compound. Researchers often use measurement of absorbance 10 min after mixing a sample with the FRAP reaction solution to calculate TAC. The FRAP solution has been shown to alter absorbance over time by ca 0.0010–0.0020 per hour, under storage conditions. This article intends to show that some substances do not fully or sufficiently react within the common analysis period. It is evident from the results that some substances react more quickly and others very slowly. Absorbance in relation to various phenols was measured. Compared to the levels of absorbance at 10 min, mean absorbance at 48 h was higher by 5,395% for vanillin, 426% for caffeic acid, 170% for sinapinic acid, 67% for gallic acid, 19% for syringic acid, and only by 4% for Trolox. Results for vanillin and caffeic acid indicate potential auto-catalysis.

High-temperature-ultrafine precipitate strengthened (HT-UPS) steel is a potential structural material for advanced nuclear reactors; however, its irradiation response is not well understood. This research provides insight into irradiation-induced effects, such as precipitate evolution mechanisms and four-dimensional morphological evolution, in HT-UPS steel using synchrotron micro-computed tomography. Identical specimens were characterized pre-irradiation and post-irradiation following neutron exposure up to 0.3 displacements per atom at 600 °C. Irradiation effects were also differentiated from the annealing response of precipitates. Following neutron irradiation, the average Cr23C6 precipitate size reduced, affected by the synergy of nucleation and growth, ballistic dissolution, and inverse coarsening, which was observed at fluences an order of magnitude lower than previously observed. Annealing at 600 °C for 32 h increased the average Cr23C6 precipitate size and decreased the phase fraction, attributed to precipitate coarsening. The precipitate morphology evolution and resultant mechanisms can be utilized to parameterize and validate microstructural models simulating radiation damage or annealing.

Currently, the problem of diagnosing pleuropulmonary blastoma in children remains relevant, because this pathology often runs under the guise of other nosologies, including pneumonia, and is extremely difficult to diagnose. Currently there are no pathognomonic clinical symptoms, specific diagnostic criteria for this disease, almost 60% of patients have nonspecific symptoms. This article presents a rare clinical case of biphasic pulmonary blastoma in a child who was examined and treated at the Ivano-Frankivsk Regional Children's Clinikal Hospital Ivano-Frankivsk Regional Council. The main clinical manifestations, diagnosis and treatment of biphasic blastoma of the lungs in a child based on the observation of a 5-year-old girl who was hospitalized for acute abdominal pain, chest pain and cough. After clinical — laboratory and instrumental methods of examination, right-sided pneumonia and exudative pleurisy were diagnosed. The set of treatment measures did not give the expected positive effect, improving the patient's condition. Additional testing is required for suspected breast cancer. It has been established that the best method for verifying the diagnosis of pulmonary blastoma is multislice computed tomography with intravenous bolus contrast and immunohistochemical examination of the biopsy. The methods of treatment used in this case, including anti-inflammatory and polychemotherapy according to the scheme, the use of radical treatment at the National Cancer Institute in Kyiv — surgery right pneumonectomy with pericardial resection. The child is currently in stable remission for 4.5 years. The described clinical case demonstrates the difficulty of diagnosing lung blastoma in children due to the lack of typical clinical manifestations. The research was carried out in accordance with the principles of the Helsinki declaration. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: children, pneumonia, blastoma, pulmonology, diagnosis, treatment.
Addressing fluctuation in article choice by Japanese learners of L2 English through explicit instruction
Authors: Snape Neal , Umeda Mari
Published: January 2022

This study examines the role of explicit instruction in article meanings to L1-Japanese learners of L2-English. An instruction group (n = 21), a control group (n = 16) and a native English speaker group (n = 9) participated in this study. Participants were asked to rate the acceptability of [±definite] and [±specific] sentences on a scale of 1–4 (1 = unacceptable; 4 = acceptable) in relation to a context for pre- and three post-tests. A pre-test was administered to both groups before instruction began and three post-tests were given to both groups. The instruction group received seven, sixty-minute lessons across seven weeks on instruction in the concepts of definiteness and specificity. Post-test 1 was administered to all participants at the end of the instruction period; post-test 2 was given after a twelve-week summer break; post-test 3 was one year after instruction had ended. The findings show that the instruction group made some gains in consolidating their understanding of the concepts during the instruction period, but after one year little explicit knowledge was retained.
Classroom input to accelerate feature reassembly of English generics
Authors: Abumelha Mary
Published: January 2022

This is an experimental study on the effect of explicit and implicit classroom input on the acquisition of English generics by L1-Najdi Arabic speakers. Following a feature-based contrastive analysis, acquisition difficulties are predicted with indefinite singular and bare plural contexts. The experiment included fifty-four students divided into two experimental groups and one uninstructed control group. One experimental group received implicit input by using genre analysis of texts reinforced with generic noun phrases (NPs), and the other group received explicit grammatical ‘focus on form’ on generics. Two instruments were used: a forced choice task and a sentence repetition task conducted as pre-tests, post-tests and delayed post-tests. The results showed a significant increase in the total scores of both experimental groups, but a long-term effect was only found with the explicit group. The forced choice task showed significant improvement in the explicit group's accuracy on generic indefinite singular and bare plural contexts and long-term improvement on the bare plural. The explicit group's results on the repetition task show temporary improvement in the generic indefinite singular post-test. In general, the results suggest that explicit input is more effective than implicit input. Implications on acquisition difficulties and instruction are discussed.
Specificity and article use
Authors: Sabir Mona
Published: January 2022

This study reports the findings of a classroom intervention experiment investigating the effectiveness of explicit instruction in teaching the English articles’ semantic properties (definiteness and specificity) to Hejazi Arabic-speaking learners. Additionally, the study explores whether learners fluctuate (use the instead of a/ an and vice versa) in contexts where the taught semantic properties do not match. Fifty-four Hejazi Arabic-speaking participants were divided into two groups (instructed and control/uninstructed). The instructed group received explicit instruction on specificity and definiteness, since specificity is currently not taught to learners of English whereas definiteness is. The control group received traditional English language lessons with no explicit instruction on article semantics. By comparing the participants’ performance with twenty-three native English speakers, the findings of the study show learners’ sensitivity to specificity in article choice. They further show evidence supporting explicit instruction. The instructed group outperformed the uninstructed group and this effect was sustained until the delayed post-test with respect to average effects. The paper concludes that generative linguistics can inform the language classroom by predicting areas of acquisition difficulty. It also stresses that explicit language instruction is more beneficial than standard classroom instruction in teaching articles. On the basis of the findings, theoretical and pedagogical implications are discussed.
