Subsektor perikanan memiliki peran dalam menunjang perkembangan ekonomi nasional, seperti penciptaan lapangan pekerjaan, peningkatan kesejahteraan masyarakat, serta diharapkan mampu meningkatkan asupan gizi masyarakat. Seperti sektor-sektor lainnya di bidang pertanian, sektor perikanan juga memiliki tingkat resiko dan ketidakpastian yang tinggi, karena selain skill dan pengetahuan, alam juga merupakan salah satu penentu keberhasilan suatu usaha. Untuk itu, seorang petani harus memiliki jiwa kewirausahaan agar mampu menjalankan usahanya dengan baik. Penelitian ini dilakukan untuk menganalisis karakteristik kewirausahaan, kinerja usaha, dan hubungan antara karakteristik kewirausahaan dengan kinerja usaha pembudidaya ikan nila yang ada di Kecamatan Padakembang, Kabupaten Tasikmalaya. Penelitian dilakukan bulan Februari hingga Agustus 2021. Menggunakan metode survei dengan instrumen kuesioner, sampel responden sebanyak 31 pembudidaya ikan nila. Alat analisis yang digunakan adalah analisis deskriptif dan analisis korelasi Rank Spearman. Tujuan dari penelitian ini adalah untuk mengetahui bagaimana karakteristik kewirausahaan pembudidaya ikan nila, bagaimana kinerja usaha pembudidaya ikan nila dan apakah ada hubungan antara karakteristik kewirausahaan dengan kinerja usaha pembudidaya ikan nila di Kecamatan Padakembang Kabupaten Tasikmalaya. Hasil menunjukkan bahwa karakteristik kewirausahaan pembudidaya ada pada kategori tinggi, hal tersebut berarti secara keseluruhan pembudidaya telah memiliki karakteristik kewirausahaan yang baik. Kinerja usaha pembudidaya ada pada kategori tinggi, hal tersebut berarti secara keseluruhan pembudidaya ikan telah memiliki kinerja usaha yang baik. Hubungan antara karakteristik kewirausahaan dengan kinerja usaha memiliki hubungan yang positif dan signifikan dengan koefisien korelasi sebesar 0,564. Hal ini berarti ketika karakteristik kewirausahaan meningkat maka kinerja usaha cenderung akan meningkat.

Published: December 2022

Permintaan yang cukup tinggi akan tomat beef kepada Serenity Farm sebagai salah satu produsen tomat beef di daerah Lembang, Kabupaten Bandung masih belum sepenuhnya terpenuhi. Salah satu penyebab hal tersebut adalah kurang optimalnya pengelolaan kadar air pada media tanam yang digunakan. Kadar air media tanam yang stabil dapat mencegah penguapan air berlebih dari permukaan tanah, serta mencegah tanaman mengalami stres. Selain itu, kadar air media tanam dipengaruhi oleh iklim, spesifikasi tanaman dan media tanam itu sendiri, sehingga cukup sulit diprediksi. Kadar air media tanam dapat mencapai titik kritis bila telat melakukan penyiraman dan menyebabkan kelayuan permanen tanaman. Penelitian ini bertujuan untuk mengembangkan model prediksi kadar air media tanam budidaya tomat beef di greenhouse Serenity Farm menggunakan machine learning. Model prediksi kadar air ini dikembangkan untuk mencegah tanaman mengalami kekeringan, dengan membantu petani dalam pengambilan keputusan penyiraman. Algoritma pembelajaran yang digunakan adalah regresi linear berganda dengan variabel bebas yang terdiri dari data Hari Setelah Tanam (HST), jumlah penggunaan air penyiraman (mL/3 jam), suhu media tanam (oC/3 jam), dan kadar air media tanam (%/3 jam) 3 jam sebelumnya. Sedangkan nilai prediksi kadar air media tanam (%/3 jam) 3 jam berikutnya dijadikan variabel terikat. Model yang dibuat telah diuji dan divalidasi dengan tingkat akurasi masing-masing 83,80% dan 72,02%. Hasil tersebut menunjukkan bahwa model prediksi yang dikembangkan dapat diterapkan dalam memprediksi kadar air media tanam tomat beef di Serenity Farm.

Published: December 2022

Introduction
Coronavirus disease 2019 (COVID-19) disease increases risk of venous thromboembolisms (VTE), primarily deep vein thrombosis and pulmonary embolism. Only a few cases of cerebral venous sinus thrombosis (CVST) in association with a COVID-19 infection have been reported and are limited to acute COVID-19 disease. Hypercoagulable conditions persist in postacute COVID-19 disease, which carries an increased risk of VTE.

Case presentation
We report a case of CVST and stroke 56 days post-COVID-19 infection presenting with an atypical clinical picture.

Discussion
To the best of our knowledge, this is one of the first observations of CVST in the postacute phase of COVID-19 disease. Clinicians should be aware of this potential late complication and should consider appropriate diagnostic imaging techniques in patients with COVID-19-infection history.

Published: December 2022

Abstract

OBJECTIVE
This study aims to quantitatively characterize the passive kinematics of the healthy, soft tissue-intact equine stifle to establish an objective foundation for providing insights into the etiology of stifle disorders and developing a possible surgical treatment for stifle degenerative disease.

ANIMALS
5 whole-horse specimens.

PROCEDURES
Reflective markers with intracortical bone pins and a motion capture system were used to investigate the stifle joint kinematics. Kinematics of 5 whole-horse specimens euthanized within 2 hours were calculated for internal/external rotation, adduction/abduction, and cranial/caudal translation of the medial and lateral femoral condyles and estimated joint contact centroids as functions of joint extension angle.

RESULTS
From 41.7° to 121.6° (mean ± SD, range of motion: 107.5° ± 7.2°) of joint extension, 13° ± 3.7° of tibial external rotation and 6° ± 2.7° of adduction were observed. The lateral femoral condyle demonstrated significantly greater cranial translation than the medial during extension (23.7 mm ± 9.3 mm vs. 14.3 mm ± 7.0 mm, P = .01). No significant difference was found between the cranial/caudal translation of estimated joint contact centroids in the medial and lateral compartment (13.3 mm ± 7.7 mm vs. 16.4 mm ± 5.8 mm, P = .16).

CLINICAL RELEVANCE
The findings share similarities with kinematics for human knees and sheep and dog stifles, suggesting it may be possible to translate what has been learned in human arthroplasty to treatment for equine stifles.

Published: December 2022

Abstract

OBJECTIVE
To develop a trivalent genetically engineered inactivated Escherichia coli vaccine (K88ac-3STa-LTB) that neutralizes the STa toxin by targeting fimbriae and entertoxins for the treatment of enterotoxigenic E coli.

ANIMALS
18- to 22-g mice, rabbits, pregnant sows.

PROCEDURES
Using PCR, the K88ac gene and LTB gene were cloned separately from the template C83902 plasmid. At the same time, the 3 STa mutant genes were also amplified by using the gene-directed mutation technology. Immune protection experiments were performed, and the minimum immune dose was determined in mice and pregnant sows.

RESULTS
The ELISA test could be recognized by the STa, LTB, and K88ac antibodies. Intragastric administration in the suckling mouse confirmed that the protein had lost the toxicity of the natural STa enterotoxin. The results of the immune experiments showed that K88ac-3STa-LTB protein could stimulate rabbits to produce serum antibodies and neutralize the toxicity of natural STa enterotoxin. The efficacy test of the K88ac-3STa-LTB-inactivated vaccine showed that the immune protection rate of the newborn piglets could reach 85% on the first day after suckling. At the same time, it was determined that the minimum immunization doses for mice and pregnant sows were 0.2 and 2.5 mL, respectively.

CLINICAL RELEVANCE
This research indicates that the K88ac-3STa-LTB trivalent genetically engineered inactivated vaccine provides a broad immune spectrum for E coli diarrhea in newborn piglets and prepares a new genetically engineered vaccine candidate strain for prevention of E coli diarrhea in piglets.

Published: December 2022

Abstract
Antioxidant enzymatic activity and soluble protein content in Robinia pseudoacacia L. (black locust), invasive tree in Europe, plants were determined under feeding conditions of the caterpillars of Parectopa robiniella Clemens, 1863, invasive miner in Europe, in trees of three (I, II, III) age groups (5–10, 15–25, and 40 years). Biochemical analysis data showed significant differences between reference and experimental leaf samples in different urban ecosystems. There was no association between changes in catalase and peroxidase activity and protein content under the influence of leaf blotch miners depending on the tree age. Significant variability of proteins under P. robiniella influence was noted; the highest of its values were recorded in the leaves of ІІІ-aged trees. In most plantings (and especially in trees of age group III), an increase (1.2 to 2.7 times) in GPx activity or the absence of its changes was registered both in the ecologically favorable zone and in the locations affected by emissions from road transport and industrial enterprises. Plants of age groups I and II in the emission areas of metallurgical, pipe-rolling, and chemical industries experienced a significant decrease in GPx activity (by 20.2–44.6%) in the leaves damaged by the phytophage. In most of the plantings studied, catalase showed an increase/stability of its activity in all age groups of trees under condition of pest attack. The highest increase in САТ activity (2.1 times) was recorded in young R. pseudoacacia plants in an ecologically favorable area of the city.
Evolution of Land Cover in the Traras MTS. Region Between 1984 and 2020 by Remote Sensing and Gis (Northwest Algeria)
Authors: Farah Tahar , Taibi Nasr-Eddine , Chouieb Mohamed 
Published: December 2022

Abstract
In Algeria, the mountainous zones represent 11% of agricultural land of the country and are home to 25% of the population. The economic development and the associated urbanization have led to environmental degradation in the Traras Mountains, which are part of the Atlas Mountains. With the aim to evaluate the degradation consequences of this region, we focused on the evolution of land use and land cover over 36 years (1984–2020). Accordingly, we used Landsat and Google Earth Pro images, topographic and ecological inventory maps, as well terrain truth; our analysis tools were mainly based on ArcGIS, Global Mapper, and ENVI software. The diachronic analysis showed that the Traras Mountains lost 8,100 ha of agricultural and forestland between 1984 and 2020. Relating to this, we point out the destruction of 9,200 ha of forested area by the fire. The urbanization also contributed to the loss of agricultural and forested areas (6,300 ha), of which 27% are located in the coastal zone. The built-up situation led to an increase of soil impermeability which causes flooding during heavy rainfall.

Abstract
We tested two summer protocols for oxytetracycline (OTC) administration on beehives to evaluate: toxicity for the bees, residues in honey and presence of genes encoding for OTC antibiotic resistance in bacteria isolated from the gut of adult bees. In July 2020, eighteen healthy colonies were divided into three groups. Two OTC treatment protocols - long and short, were devised, and one group was left untreated. We did not detect any toxicity on adult bees or brood but found OTC residues in the honey of the nest up to seven months after both treatments (210.3±221.2 µg/kg after long protocol; 216.2±238.4 µg/kg after short protocol), even in the untreated group (up to the mean 75.8±173.2 µg/kg). Antibiotic resistance genes were found, even in the untreated group, possibly due to the long exposure to antibiotics. More in-depth studies should be performed to verify how the long-term persistence of antibiotics impacted the beehive during the inactive season.

Published: December 2022

Abstract
The aim of the study was to analyse the intestinal microbiota of honey bees (Apis mellifera) treated with amitraz. In the present study, the microbiological profile of the honey bee intestines showed minor changes in the microbiota following the application of amitraz. A comparison of the numbers of bacteria and fungi revealed a positive downward trend in the number of fungi. The number of decreased bacteria, included E. coli and especially Clostridium spp., which were not isolated from the intestines of bees treated with amitraz. The number of lactic acid bacteria before and after treatment was at a similar level of 8.3 log cfu/g of intestinal contents.

Published: December 2022

Abstract
The aim of the research was to analyse land use changes and to develop a coherent base on the basis of available cartographic source materials – archival and contemporary topographic maps and spatial databases. The presented research is a continuation of works related to the cartographic visualization of changes in the distribution of the settlement network in the Noteć Forest – one of the largest forest complexes in Poland. The analysis was performed for nine villages together with their immediate surroundings, located in this area. The total surface area of lands covered by the study was 32,468 km2. Cartographic source materials were collected for selected areas. The archival maps were georeferenced and then digitized. In this way, the data has been transformed into a homogeneous system enabling further comparisons and analyses in an automated manner. Geodetic software (C-Geo), GIS (MapInfo, QGIS) and GNSS technology were used in the work. Cartographic sources can be successfully used for spatial analyses and environmental studies, providing reliable and available quantitative data. This type of research is important because it shows the changes taking place in the natural environment and can be used in works related to spatial planning, landscape ecology and social research.

Authors: Krupińska Andżelika , Ochowiak Marek , Włodarczak Sylwia , Matuszak Magdalena , Kaźmierczak Julia 
Published: December 2022

Abstract
Purifying air from dust is a very important, current topic. There are many methods to minimize the amount of dust, one of them being chamber filters. This paper presents the research results of a newly designed rectangular chamber filter. The efficiency of the dedusting process is influenced by contamination properties, but also by the construction of the apparatus, inlet, and outlet location, the ratio of certain dimensions, and the gas flow rate. The airflow containing solid particles is a multi-phase, difficult-to-describe issue, therefore an attempt to determine the trajectory of particle movement in the apparatus was carried out using the PIV method. A decrease in the dedusting efficiency was observed with the increase of the gas flow rate, as well as for smaller diameters of the solid particles. The obtained values of the efficiency of the apparatus are comparable with the values obtained for the constructions discussed in other papers.
Method of purification of post-production condensates from polyester polyol production
Authors: Lewandowski Marek , Biniecka Paulina 
Published: December 2022

Abstract
Nowadays, the topics of closed-loop and eco-design are raised very often, especially in the chemical industry. To combine development with these trends, Purinova Sp. z o.o. has focused on pursuing the closed-loop use of post-production condensate from polyester polyols production. To this end, purification and distillation processes have been adapted, both at the laboratory and production scale, to receive treated condensate with decreased Chemical Oxygen Demand (COD) index. The method involves connected purification of production condensate by returning condensate to the top of the distillation column during polycondensation and two stages distillation system afterwards. The method allows for decreasing COD index and contents of diethylene glycol and 1,4-dioxane. The resulting technology has consequently allowed the use of tailored distillation in the purification of post-production condensates in the production of polyester polyols. Furthermore, the quality of the condensate obtained allowed it to be used in the closed loop of the production plant.
Zero-modified Poisson-Modification of Quasi Lindley distribution and its application
Authors: Tharshan Ramajeyam , Wijekoon Pushpakanthie 
Published: December 2022

Abstract
The Poisson-Modification of Quasi Lindley (PMQL) distribution is a newly introduced mixed Poisson distribution for over-dispersed count data. The aim of this article is to introduce the Zero-modified PMQL (ZMPMQL) distribution as an alternative to the PMQL distribution in order to accommodate zero inflation/deflation. The method of obtaining the ZMPMQL distribution jointly with some of its important properties, namely the probability mass and distribution functions, mean, variance, index of dispersion, and quantile function are presented. Furthermore, some of its special cases are discussed. The maximum likelihood (ML) estimation method is used for the unknown parameter estimation. A simulation study is conducted in order to evaluate the asymptotic theory of the ML estimation method and to show the superiority of the ML method over the method of moments estimation. The applicability of the introduced distribution is illustrated by using a real-world data set.
Comparison of confidence intervals for variance components in an unbalanced one-way random effects model

Published: December 2022

Abstract
The purpose of this paper is to study and compare the methods for constructing confidence intervals for variance components in an unbalanced one-way random effects model. The methods are based on a classical exact, generalised pivotal quantity, a fiducial inference and a fiducial generalised pivotal quantity. The comparison of criteria involves the empirical coverage probability that maintains at the nominal confidence level of 0.95 and the shortest average length of the confidence interval. The simulation results show that the method based on the generalised pivotal quantity and the fiducial inference perform very well in terms of both the empirical coverage probability and the average length of the confidence interval. The classical exact method performs well in some situations, while the fiducial generalised pivotal quantity performs well in a very unbalanced design. Therefore, the method based on the generalised pivotal quantity is recommended for all situations.
An investigation into the use of metadiscourse in undergraduates’ abstracts in social sciences
Authors: Ruonan Lin , Al-Shaibani Ghayth Kamel Shaker 
Published: December 2022

Abstract
There is very little research on the use of metadiscourse markers in abstracts across different disciplines (especially in a single study) in the research of undergraduates as novice researchers, and little qualitative research has been done on the topic in EFL and ESL contexts altogether. Thus, the purpose of this study is to examine the use of metadiscourse markers in EFL and ESL undergraduates’ abstracts in social sciences across three disciplines (English Language and Communication, Mass Communication, and Psychology) in the Faculty of Social Sciences and Liberal Arts at UCSI University, a Malaysian private university. We adopt Hyland’s (2005) interpersonal model which involves two main categories – interactive metadiscourse and interactional metadiscourse – to analyse all 62 abstracts collected from the 2016 Colloquium held at the faculty. The method used is qualitative to categorize the metadiscourse markers accordingly as well as counting their frequencies. The findings showed that the interactional metadiscourse markers were used nearly twice as often as the interactive discourse markers for the three disciplines, and the most used markers are boosters. The most used interactive metadiscourse markers are transitions, followed by frame markers, evidentials, code glosses, and endophoric markers. The findings can be used by ESL and EFL instructors when teaching students learning argumentative writing and research writing to use metadiscourse markers to make arguments and write proper critiques to reflect their stance and voice. This research adds some insights into this neglected genre of academic discourse at the undergraduate level.
