An inquiry on publishersâ€™ criteria for recruitment of translators

This study aimed to investigate the criteria considered by Iranian publishers for admitting translators. In order to achieve this purpose, the qualifications developed by Samuelson-Brown were employed to design a 19-item Likert scale questionnaire on a continuum from â€˜strongly agreeâ€™ to â€˜strongly disagreeâ€™. Some of the qualifications mentioned in the questionnaire were academic degree, translation competence, work experience, proficiency test, translatorsâ€™ sense of responsibility for their task and the direct relationship between the publishers and the translators. Next, it was handed out to 140 Iranian publishers who were randomly selected as the participants from different parts of Iran for data collection. The collected data were analysed both qualitatively and quantitatively using the chi-squared test to see whether there were any significant relationships between each item and the participantsâ€™ attitudes. The qualitative results showed that almost all participants agreed with considering most qualifications as their own criteria to recruit translators, of course with some variations in their opinions on the significance of the variables of interest. However, the result of the chi-squared test showed a significant relationship only between four variables of inclusion of proficiency test, computer literacy, the translatorsâ€™ relationship with the publisher and gender. The results can have some practical implications on translation course developers, students and teachers. Â Â
Vegetation Changes in Response to Climatic Factors and Human Activities in Jilin Province, China, 2000–2019

Dynamic change in vegetation is an integral component of terrestrial ecosystems, which has become a significant research area in the current context of global climate warming. Jilin Province in northeast China is an ecologically fragile area, and there is an urgent need to understand its vegetation changes and responses to both climatic factors and human activities. The normalized difference vegetation index (NDVI) was used to analyze trends in vegetation growth, and indicated significant growth overall. The NDVI of different vegetation cover types is increasing, indicating that the vegetation is continuously greening, and in descending order, the growth trends were grassland (0.0035/year) > permanent wetland (0.0028/year) > cropland (0.0027/year) > forest land (0.0022/year) > barren land (−0.0001/year). Grassland and cropland vegetation types included the most severely degraded areas, with fluctuating NDVI values. Precipitation was the main positive controlling climatic factor of NDVI in the western regions of the study area, while average temperature was the main factor in the eastern regions. Precipitation was the main climatic control factor for grassland and cropland, while forest land was limited by precipitation and average temperature. Barren land and permanent wetland were slightly negatively correlated with precipitation. From 2000 to 2019, the residual values for NDVI increased from −0.0121 to 0.0116, and the impact of human activities on vegetation changed from negative to positive. By 2019, the proportion of positively affected zones was as high as 94.01%, and the negatively affected zones were mainly distributed across transitional areas of cropland and grassland, and urban and built-up land and forest land.
THE PERCEPTION OF SWAMP BUFFALO BREEDERS TOWARDS PALM OIL PLANTATIONS IN KURIPAN DISTRICT BARITO KUALA REGENCY SOUTH KALIMANTAN PROVINCE

The opening of palm oil plantations, both of the nucleus and plasma, aims to increase the sources of state revenue and employment opportunities for its surrounding community. However, in this case, part of the land is swamp buffalo grazing that has been used by the community for generations. This situation is prone to social conflict. This study aims to determine the perception of swamp buffalo breeders on the palm oil plantations in Kuripan District, Barito Kuala Regency, South Kalimantan Province. This study uses mixed methods, namely as a questionnaire to collect the quantitative data and interview guidelines to obtain the qualitative data. The respondents were all 38 swamp buffalo breeders, while the informants were some of the breeders, the formal figures, and informal leaders who knew about the existence of swamp buffalo and the process of entering the palm oil plantations. The results showed that the breeders' perception of the palm oil plasma plantations as a stimulus or object that stimulated the senses was on the average of 1.44 (on a scale of 1-4) in the bad category. The cognitive processes for assessing or considering, as well as relating an event to the other events are included in the known category, with a score of 2.93. The breeder's response to the action is less approved, with a score of 2.38. The breeders also did not get any consequences from the plantation side, with a score of 1.63. It can be concluded that the perception of swamp buffalo breeders towards the palm oil plantations is in the poor category, with a score of 2.07.
Grid Harmonic Current Correction Based on Parallel Three-Phase Shunt Active Power Filter

This article presents a finite-set model predictive control (FS-MPC) applied to the shunt active power filters (SAPF) based on three-phase inverters connected in parallel sharing the same dc-link. The discrete-time model of the system is used to predict the future value of the grid, circulation, and offset currents. The presence of circulation and offset currents occurs due to the connection of the two inverters in parallel sharing the same dc-link. There are 64 switching state vectors for SAPF and, in order to reduce the burden of calculation, only 30 switching states are chosen and applied, however keeping the advantages of the FS-MPC algorithm. The control strategy ensures the sinusoidal shape of the grid current, high power factor, and circulating and offset currents suppression. The FS-MPC has its performance compared to the pulsewidth modulation (PWM) strategy considering the SAPF with two parallel inverters, the conventional SAPF and the neutral-point-clamped SAPF. These comparisons include harmonic distortion, power semiconductor losses, and analysis of dc-link capacitor losses. As a multilevel topology, the SAPF with two parallel inverters using FS-MPC present competitive efficiency and can be applied with a good performance in industrial and residential applications. Simulation results and a laboratory-scale experimental platform is used for corroborating the proposal.
Water quality characteristics of surface water and Accumulation of heavy metals in sediments and Fish of Imo River, Imo State.

Freshwater must sufficiently be in quantity and quality that would support sustainable development and survival of mankind. Physicochemical properties and heavy metal concentration of the Imo River were investigated. Four sampling stations were selected 300 m apart along the River and sampling was done between August to November. Electrical conductivity, pH, total dissolved solids, biochemical oxygen demand, oxygen demand, chloride, sulphate, phosphate and heavy metal (Cu, Pb, Mn, Cr, Zn, Fe , Cd, Ni and As) were the parameters determined. Standard methods were employed for physicochemical analysis of water samples. Concentrations of heavy metals in water, sediment and fish samples were determined using atomic absorption spectrophotometer. The river was slightly alkaline in all the sampling stations (pH 7.10 to 8.60). Sulphate had the highest concentration (210.30 mg/L to 360.0 mg/L) nitrite had the lowest mean concentration (1.52 mg/L) among the anions in water samples. Nickel had the lowest concentrations in water (0.001mg/L) and fish (0.01 mg/kg) respectively. Iron was the most abundant metal in sediment (9645 mg/kg) and in fish tissue (13.51 mg/kg). Zinc had the greatest concentration in water (21.20 mg/L) whereas cadmium had the lowest concentration in sediments. Heavy metal concentrations were higher in sediments than in fish tissue and water. Imo River was contaminated with lead, copper, zinc and manganese.
Torque Quality Improvement of Switched Reluctance Motor Using Ant Colony Algorithm

: The switched reluctance motors (SRMs) are gaining increasing interest in many industrial applications, including electric vehicles (EVs). However, their main drawback is the high torque ripple and noise. This paper presents an optimization-based method to improve the torque quality of SRM drives. The focus is on reducing torque ripple without complicating the control algorithm. The switching angles are optimized using a multistage ant colony algorithm (MSACA). The multistage algorithm provides a better search capability that fits appropriately with the high nonlinearities of SRMs. The finite element method (FEM) is employed to calculate the magnetic characteristics of the tested 8/6 SRM prototype. These characteristics are used within the MATLAB environment in the form of lookup tables to model the machine. The performance indices are calculated within the simulation model. Series of simulation results are included to show the effectiveness of the proposed control. Besides, experimental verification is also included to verify the theoretical findings.
Galactomannans for Entrapment of Gliomastix murorum Laccase and Their Use in Reactive Blue 2 Decolorization

In the present study, a novel laccase from ascomycete Gliomastix murorum was produced in agro-industrial wastes and entrapped in galactomannan beads for Reactive Blue 2 (Rb-2) decolorization. The maximum laccase production in agave bagasse-based medium occurred at 72 h (1798.6 UL−1). Entrapped laccase decolorized ˃80% of 0.5 mM Rb-2 in 2 h without the addition of redox mediator. Km for Rb-2 substrate was 1.42 mM, with a Vmax of 1.19 µmol min−1 for entrapped laccase. Galactomannan matrices produce stability to acid pH (2–5) and temperatures from 20–70 °C. Reusability assays showed that entrapped laccase could retain efficient Rb-2 decolorization of ˃80% six times. In general, galactomannan used for entrapment of laccase provides economic advantages in large-scale wastewater treatment due to its natural origin and efficient results.

EUS-guided drainage of pancreatic fluid collection, using a modified technique of cystotome alone without a FNA needle

Background: Endoscopic ultrasound (EUS)-guided drainage for pancreatic fluid collection (PFC) involves puncture with a fine-needle aspiration (FNA) needle, followed by tract dilation involving exchange of multiple accessories, and finally deployment of stent. The procedure is time consuming and carries a risk of loss of wire access and hence technical failure. We used a modified technique with a 10-F cystotome alone instead of a FNA needle and dilators. Methods: We retrospectively analysed records of consecutive patients who had undergone EUS-guided drainage of PFC using a modified technique, with puncture of PFC using a 10-Fcystotome, followed by passage of a guidewire through it into the PFC cavity and deployment of a biflanged, 2-cm-long, fully covered self-expanding metal stent over it. Technical and clinical success rates and procedure time were assessed. Results: Forty-five patients underwent PFC drainage, median age was 35 (12–76), and 35 (77.8%) were males. The median (range) duration of symptoms was 125 (38–1080) days, while the median PFC size was 11.8 × 11 × 11 cm, and the follow-up period after stent removal was 111 ± 72 (18–251) weeks. The procedure took 10 (8–12) min and had technical and clinical success rates of 100 and 97.8%, respectively. Minor complications occurred in six (13.3%) patients, while recurrence occurred in one. Conclusion: EUS-guided drainage of PFC using a cystotome is a quick, effective and safe procedure. It may also be less expensive since it obviates the use of FNA needles and dilators, and is likely to be a useful alternative to the conventional technique.
A New Hybrid Voltage Source Converter With Reduced Active Switch Count for HVDC Applications

This paper presents a new hybrid voltage source converter topology with reduced active switch count for HVDC applications. It consists of a block of switches in the upper converter arms and cascaded switch-diode cells in the lower converter arms. The cascaded switch-diode cells in the lower converter arms produce a multilevel output voltage while the switch blocks in the upper converter arms perform rectification. The switches in the upper converter arms conduct for one-third of the fundamental line period as dictated by the relative magnitude of the input line-to-neutral voltages. Only one of the three phase blocks of switches conduct at a time. Compared to other voltage source converter topologies with similar structure and operation to this topology, the proposed topology has lower number of devices. Therefore, it has lower converter footprint and cost. More importantly, it reduces the semiconductor device power losses significantly due to the lower number of active switches (lower switching loss) and the lower number of devices in current conduction path (lower conduction loss). The basic operation principle of the proposed converter and its associated control strategy that regulates the power exchange between the converter, and the ac and dc networks are described in detail and verified using both simulation and experimental results.
CHROMOSOME NUMBER VARIATION IN PART OF THE FLORA
OF PROTECTED WILD AREAS IN THE ARAUCANiA REGION OF SOUTHERN CHILE

An analysis was made of the correspondence between species diversity and chromosome number (CN) diversity across 13 Protected Wild Areas (PWA) in the Araucanía Region of southern Chile, encompassing 84 plant species with available cytogenetic data. Our aim was to establish whether higher species diversity within a PWA entails higher CN variation as based on the index of chromosome number heterogeneity (ICNH). The CN data were extracted from databases for Chilean plants, and the ICNH for the flora of each PWA was calculated. Results showed that in nine PWA the species diversity clearly correlates with CN diversity. However, four PWA do not fit this trend. The percentage of species with CN data varied between 9.6% and 24.5% among PWA, with 11 PWA presenting percentages higher than 11%. A 27.3% of the Chilean vascular plant species with available cytogenetic data were studied here for the 13 PWA. The results obtained by studying one part of the flora with available CN data suggest that the PWA could be an important reservoir of genetic diversity at a chromosome level, thus justifying the protective role of the PWA as biodiversity conservation sites. Key words: Chromosome number heterogeneity; floristic diversity; Chilean flora.
Preparation and characterization of petroleum-based mesophase pitch by thermal condensation with in-process hydrogenation

A petroleum aromatic-rich component was used to prepare mesophase pitch by thermal condensation. In-process hydrogenation method was employed to achieve the hydrogenation reaction of intermediates generated during the thermal reaction using tetrahydronaphthalene (THN) as a hydrogen donor. Impacts of in-process hydrogenation on the properties of intermediates and mesophase pitches were investigated. It was found that the in-process hydrogenation was conducive to the generation of hydrogenated intermediates with concentrated extracted component distribution, uniform molecular structure and abundant naphthenic structures. The characterizations of mesophase pitches showed that the in-process hydrogenation contributed to the preparation of mesophase pitch with concentrated extracted component distribution, low softening point, large domain structure and ordered crystal structure. This was due to the increasing contents of naphthenic structures in intermediates. Moreover, the increase of methylene bridges in the product was the critical reason for improving the product's properties.
Mitochondrial Transfer through Pericardium Contributes to Functional Recovery in Ischemic Cardiomyopathy

Although mesenchymal stem cell transplantation has been efficacious in the treatment of ischemic cardiomyopathy, the underlying mechanisms remain unclear. Herein, we investigated whether mitochondrial transfer could explain the success of cell therapy in ischemic cardiomyopathy. Mitochondrial transfer was examined in co-cultures of human adipose-derived mesenchymal stem cells and rat cardiomyocytes under hypoxic conditions. Functional recovery was monitored in a rat model of myocardial infarction following human adipose-derived mesenchymal stem cell transplantation. In vitro, we observed mitochondrial transfer, which required formation of cell-to-cell contacts and synergistically enhanced energy metabolism. Rat cexhibited mitochondrial transfer three days following human adipose-derived mesenchymal stem cell transplantation to the ischemic heart surface post myocardial infarction. We detected donor mitochondrial DNA in the recipient myocardium concomitant with a significant improvement in cardiac function. In conclusion, mitochondrial transfer is vital for successful cell transplantation therapies and promotes improved treatment outcomes in ischemic cardiomyopathy.
Transcriptome profiling of gene expression in phosphate-solubilizing bacterium Acinetobacter sp. strain m01 interacting with melon (Cucumis melo L.) seedling

ABSTRACT Phosphorus (P) is an important element for plant and bacteria growth. The response of bacteria to P transformation into adsorbed forms and their interaction with plants remain unclear. In this study, the mechanisms involved in P adsorption in plants and bacteria were analyzed by a RNA-seq technology. A phosphate-solubilizing bacterium (PSB) Acinetobacter sp. strain M01 was used in the transcriptome profiling of expressed genes and during interaction with melon (Cucumis melo L.). Results showed that the majority of genes related to cellular component and molecular function were up-regulated. The genes in the melon plant treated with M01 were down-regulated compared with those in the control. Genes for phenylalanine metabolism, amino acid, glycerolipid metabolism were identified in M01 DEGs related to transport and catabolism, carbohydrate metabolisms, and amino acid transport were marked in melon. This study provides an understanding of the gene interaction in PSB to fixed P and melon.
Spray dried solid dispersions of piroxicam in carboxymethyl sago cellulose using aqueous solvents: A simple, novel and green approach to produce enteric microparticles with enhanced dissolution

Abstract Piroxicam-CMSC solid dispersions were produced by spray drying from aqueous solvents. Depending on the drug-polymer ratio, loading and entrapment efficiency of CMSC microparticles were 6.8–46.75 and 40.79–60.35% w/w, respectively. Scanning electron microscopy revealed non-spherical geometry and agglomeration of the spray-dried particles. The average size of the particles ranged from 7 to 170 µm. Infrared spectroscopy, differential scanning calorimetry, and X-ray diffraction confirmed intact crystalline piroxicam in the microparticles. In gastric pH, microparticles and native piroxicam have shown less than 25% and more than 45% of drug dissolution, respectively in 2 h. In contrast, at pH 7.4, microparticles have shown 80% of drug dissolution; whereas native piroxicam achieved only 30% of dissolution by 30 min. The spray-dried CMSC particles are efficient in restricting drug release in gastric pH and enhance drug dissolution in intestinal pH. The method is eco-friendly as it uses aqueous solvents and non-toxic materials.
The DFT/MRCI method

In the past two decades, the combined density functional theory and multireference configuration interaction (DFT/MRCI) method has developed from a powerful approach for computing spectral properties of singlet and triplet excited states of large molecules into a more general multireference method applicable to states of all spin multiplicities. In its original formulation, it shows great efficiency in the evaluation of singlet and triplet excited states which mainly originate from local one‐electron transitions. Moreover, DFT/MRCI is one of the few methods applicable to large systems that yields the correct ordering of states in extended π‐systems where double excitations play a significant role. A recently redesigned DFT/MRCI Hamiltonian extends the application range of the method to bi‐chromophores such as hydrogen‐bonded or π‐stacked dimers and loosely coupled donor–acceptor systems. In conjunction with a restricted‐open shell Kohn–Sham optimization of the molecular orbitals, even electronically excited doublet and quartet states can be addressed. After a short outline of the general ideas behind this semi‐empirical method and a brief review of alternative approaches combining density functional and multireference wavefunction theory, formulae for the DFT/MRCI Hamiltonian matrix elements are presented and the adjustments of the two‐electron contributions are discussed. The performance of the DFT/MRCI variants on excitation energies of organic molecules and transition metal compounds against experimental or ab initio reference data is analyzed and case studies are presented which show the strengths and limitations of the method. Finally, an overview over the properties available from DFT/MRCI wavefunctions and further developments is given.
