This research proposed a portable wideband horizontally-polarized directional antenna scheme with a radome for digital terrestrial television reception. The operating frequency band of the proposed antenna scheme is 470–890 MHz. The portable antenna scheme was an adaptation of the Yagi-Uda antenna, consisting of a folded bowtie radiator, a semicircular corrugated reflector, and a V-shaped director. Simulations were carried out, and an antenna prototype was fabricated. To validate, experiments were undertaken to assess the antenna performance, including the impedance bandwidth (|S11| ≤ −10 dB), gain, and unidirectionality. The measured impedance bandwidth was 75.93%, covering 424–943 MHz, with a measured antenna gain of 2.69–4.84 dBi. The radiation pattern was of unidirectionality for the entire operating frequency band. The measured xz- and yz-plane half-power beamwidths were 150°, 159°, 160° and 102°, 78°, 102° at 470, 680, and 890 MHz, with the corresponding cross-polarization below −20 dB and −40 dB. The radome had a negligible impact on the impedance bandwidth, gain, and radiation pattern. The power obtained for the outdoor test, at 514 MHz, was 38.4 dBµV (−70.4 dBm) with a carrier-to-noise ratio (C/N) of 11.6 dB. In addition, the power obtained for the indoor test was 26.6 dBµV (−82.2 dBm) with a C/N of 10.9 dB. The novelty of this research lies in the concurrent use of the Yagi-Uda and bowtie antenna technologies to improve the impedance bandwidth and directionality of the antenna for digital terrestrial television reception.

Despite sport being a vehicle through which youth may achieve positive developmental outcomes, maltreatment in the youth sport context remains a significant concern. With increased athlete advocacy and research demonstrating the high prevalence of maltreatment in sport, and the urgent need to address it, many international organisations have created child protection in sport initiatives. Of particular focus to athletes and researchers is the provision of evidence-based comprehensive education and independent reporting mechanisms for athletes who experience harm. The current study examined the extent to which the publicly accessible information provided by three sport-specific child protection organisations regarding education and reporting is aligned with recommendations provided by researchers and athletes. With regard to education, the findings highlight accessibility, programming for various stakeholders, and coverage of topics of interest (e.g., forms of harm and reporting processes). However, educational information about equity, diversity, and inclusion and information on how to foster positive environments in sport was lacking. For reporting mechanisms, results showed that each organisation’s approach to receiving reports of maltreatment varied, including their ability to directly intake, investigate, and sanction instances of maltreatment. The findings are interpreted and critiqued considering previous literature and recommendations for future research and practice are suggested.

Single or combined plant growth-promoting bacteria (PGPB) strains were widely applied as microbial agents in cadmium (Cd) phytoextraction since they could promote plant growth and facilitate Cd uptake. However, the distinct functional effects between single and combined inoculants have not yet been elucidated. In this study, a field experiment was conducted with single, double and triple inoculants to clarify their divergent impacts on plant growth, Cd uptake and accumulation at different growth stages of Brassica juncea L. by three different PGPB strains (Cupriavidus SaCR1, Burkholdria SaMR10 and Sphingomonas SaMR12). The results show that SaCR1 + SaMR10 + SaMR12 combined inoculants were more effective for growth promotion at the bud stage, flowering stage, and mature stage. Single/combined PGPB agents of SaMR12 and SaMR10 were more efficient for Cd uptake promotion. In addition, SaMR10 + SaMR12 combined the inoculants greatly facilitated Cd uptake and accumulation in shoots, and enhanced the straw Cd extraction rates by 156%. Therefore, it is concluded that the application of PGPB inoculants elevated Cd phytoextraction efficiency, and the combined inoculants were more conductive than single inoculants. These results enriched the existing understanding of PGPB agents and provided technical support for the further exploration of PGPB interacting mechanisms strains on plant growth and Cd phytoextraction, which helped establish an efficient plant–microbe combined phytoremediation system and augment the phytoextraction efficiency in Cd-contaminated farmlands.

There is scarce information on seroconversion and adverse events after immunization (AEFI) with the fourth dose of BNT162b2. Our aim was to correlate the magnitude of the antibody response to this vaccination regimen in terms of clinical conditions and AEFI. This was an observational pilot study in which SARS-CoV-2 S1–S2 IgG antibodies titers were measured 21–28 days after the first and second dose, three months after the second dose, 1–7 and 21–28 days after the third dose, before the fourth dose, and 21–28 days after the fourth dose. We recruited 112 subjects in a hospital in Mexico, 74% women, with an average age of 43 (SD 9) years. After the first dose, subjects had a median IgG AU/mL (IQR) of 122 (1904) that increased to 1875 (2095), 3020 (2330), and 4230 (3393) 21–28 days after the second, third, and fourth doses, respectively (p < 0.01). The number (%) who experienced any AEFI between the first and fourth doses was 90 (80.4), 89 (79), 65 (58), and 69 (61.5), respectively (p < 0.001). After the fourth dose, the most frequent of AEFI was pain at the injection site (87%). There was a correlation between AEFI and gender after the fourth dose, as well as with antibody levels (p < 0.05). During the Omicron outbreak, six (5.3%) had mild COVID-19 for 8–28 days after the fourth dose. The median increase in S1/S2 IgG was 30.8-fold after the fourth BNT162b2 dose when compared with the first dose and caused mild AEFI.

Published: July 2022

The wireless charging electric tram system is presently receiving attention as an eco-friendly means of transportation. The conventional electric tram system has a similar advantage in regards to environmental pollution, but it has several problems that are caused by the overhead power supply line. The battery-type electric tram system should be considered carefully, because the battery itself is an environmentally harmful material. Therefore, the wireless charging electric tram system is regarded as an alternative means of transportation. The adequate battery capacity and the location of the wireless charging infrastructure are investigated in this study, which consider the dual operation policy, and the objective is to minimize the total investment cost. The variation of the battery capacity and the location of the wireless charging infrastructure are examined that compare Case 1, which involves the electric trams operating only in normal operations, and Case 2, which includes the electric trams operating in normal and express operations.

Published: July 2022

Epineural neurorrhaphy is a standard nerve repair method, but it is rarely reported in veterinary literature. Epineural neurorrhaphy in canine sciatic nerve injury are described in this report. An 11-month-old, castrated male Maltese dog, presented with an one-month history of non-weight bearing lameness and knuckling of the right pelvic limb. The dog showed absence of superficial and deep pain perception on the dorsal and lateral surfaces below the stifle joint. The dog had undergone femoral head and neck osteotomy in the right pelvic limb one month prior to referral at a local hospital. Based on physical and neurological examinations, peripheral nerve injury of the right pelvic limb was suspected. Radiography showed irregular bony proliferation around the excised femoral neck. Magnetic resonance imaging revealed sciatic nerve injury with inconspicuous continuity at the greater trochanter level. A sciatic nerve neurotmesis was suspected and surgical repair was decided. During surgery, non-viable tissue of the sciatic nerve was debrided, and epineural neurorrhaphy was performed to bridge a large, 20-mm defect. The superficial and deep pain perception was progressively improved and restored at 3 weeks postoperatively, and the dog exhibited a gradual improvement in motor function. At 10 weeks postoperatively, the dog showed no neurological deficit including knuckling but the tarsal joint hyperextension did not improve due to ankylosis. The dog had undergone tarsal arthrodesis and exhibited almost normal limb function without any neurologic sequela until the last follow-up at 2.5 years postoperatively.

Published: July 2022

The occurrence of metritis during the postpartum period causes serious economic losses in dairy cattle. The Micronised Purified Flavonoid Fraction (MPFF) is a polyphenolic flavonoid compound which is considered to have many health-related properties such as antibiotic, anti-inflammatory, phlebotonic, and several vascular-protecting activities. The aim was to evaluate the effects of a new strategic therapy for metritis based on MPFF intrauterine infusions during the early postpartum in dairy cows naturally infected by Escherichia coli. The clinical effects on reproductive anatomical structures and chronological involution dynamics were monitored until day 24 postpartum by ultrasonography. Moreover, uterine bacteriological and cytological (polymorphonuclear neutrophils; PMNs) profiles were analysed before and after MPFF infusion. The results showed that the success rate (% cure) at day 24 postpartum was improved significantly when using higher MPFF doses (p < 0.05). Moreover, MPFF treatment acutely diminished the size of the cervix and uterus and improved the involution process during the first 24 days (p < 0.05). The prevalence of pathogenic bacteria found in in vitro cultures was significantly variable (p < 0.01), as were the antibiotic sensitivity patterns. Pathogenic bacteria isolates decreased after MPFF applications in a dose–response fashion (p < 0.01), while isolates obtained from controls and low-dose-MPFF-treated animals were stable and similar (p > 0.05). The sensitivity patterns of pathogenic bacteria isolated in in vitro cultures from MPFF-treated animals were variable, although resistance to E. coli, Staphylococcus aureus, Bacillus spp., and coliforms was shown irrespective of the MPFF doses used. However, MPFF-treated cows showed a dose–response effect regarding PMN rates (p < 0.05). The calving-first service, calving–conception interval, and conception rate improved significantly from using higher MPFF doses (p < 0.05). In conclusion, this study shows that MPFF treatment differentially affects uterine involution, bacteriological profiles, cytological traits, and reproductive performance in metritis-positive dairy cows naturally infected by E. coli.

Evaluar el efecto de la sustitución parcial y total de harina de pescado por harina de torta de “sacha inchi” (Plukenetia volubilis) en dietas para el cultivo de juveniles de camarón (P. vannamei) es el objetivo planteado de la investigación. Se aplicaron cuatro tratamientos: T-1 (50% harina de sacha inchi, HSI +50% harina de pescado-HP), T2 (75% HSI +25% HP), T3 (100% HSI) y T4 (100% HP control), con tres repeticiones, es decir 12 unidades experimentales. Se utilizaron 360 juveniles de (P. vannamei) con peso total de 0,35 ± 0,01 g y longitud total 3,70 ± 0,17 cm respectivamente, distribuidos al azar en recipientes de pvc de 30 cm de alto por 59,5 cm de ancho y fondo de 38,7 cm, con un volumen operativo de 45 litros y 30 camarones por replica. La duración del experimento fue de 20 días, bajo un diseño completamente aleatorio, la ganancia de talla y peso fueron influenciadas significativamente (p<0,05) por las dietas formuladas. La mayor ganancia en peso (1,26 g) fue el T-4, seguido del T1 (1,13 g). En tallas no hubo diferencias entre el T1 y T4 (2,28 cm y 2,27 cm, respectivamente, presentando los menores valores para el T2 y T3. La supervivencia fue del 100% en todos los tratamientos. Se podría sustituir hasta un 50% la HP por HSI sin afectar los parámetros de crecimiento en juveniles del camarón.

Published: July 2022

El erizo de mar Arbacia stellata puede habitar en ecosistemas estuarinos, pero se desconoce la salinidad crítica en las etapas iniciales de vida para su cultivo. Para ello se evaluó el porcentaje de fertilización, desarrollo embrionario y supervivencia de A. stellata en cuatro salinidades (ups): 5, 10, 20 y 32 (control). Los gametos se obtuvieron de erizos adultos vía inyección intracelómica de 0,55 M de KCl. Los estadios de desarrollo embrionario fueron registrados mediante fotomicrografías desde la fertilización hasta larva prisma. El control presentó 100% de fertilización y supervivencia, cuyo desarrollo embrionario se completó en 20 horas hasta la fase de larva prisma. En contraste, el porcentaje de fertilización disminuyó entre 5 y 10 ups (<70%) y hubo retraso en el desarrollo embrionario (fase de gástrula >24 h) sin formación de larva prisma. Los resultados sugieren que salinidades por debajo de 10 ups son críticas para el desarrollo embrionario de A. stellata. Esta información es clave para una acuicultura viable de este erizo de mar cuando se utiliza agua de estuario en ecosistemas tropicales.

La equidad en el acceso a las oportunidades para mujeres y hombres es uno de los aspectos requeridos para mejorar los procesos de desarrollo de los profesionales. Este trabajo tiene como objetivo analizar los avances y retos de las universidades respecto a las políticas que garanticen la equidad y desarrollo profesional de sus colaboradores. Desde el análisis documental se estudia el proceso evolutivo de la legislación de Ecuador, destacando los elementos que constitucionalmente permiten la participación de la mujer en los espacios académicos durante el periodo 2008-2021; y se analiza el impacto de la pandemia por la COVID19 sobre las políticas nacionales. Entre los resultados se presenta un análisis cronológico de las políticas públicas de género que se instrumentaron en el Sistema de Educación Superior ecuatoriano para identificar los avances y tareas por cumplir. Se concluye resaltando que la presencia de la COVID19 ha limitado el avance de las políticas de equidad de género, priorizándose la prevención y conservación de la salud. En los hogares las ejecutivas, maestras y otras mujeres profesionales han visto recargadas sus agendas con los roles de madre y esposas. A ello se ha incrementado la tarea de ser maestra de sus hijos e hijas debido a la educación en línea que ha demandado mayor participación de la familia, pero que se concentra principalmente en las mujeres.

El clima laboral es considerado un factor relevante para lograr el desempeño y una buena imagen institucional. El presente estudio tuvo como objetivo analizar el impacto del clima laboral en el desempeño de los trabajadores administrativos del departamento financiero de la Universidad Técnica de Manabí. Esta investigación es de tipo no experimental, descriptiva, con un diseño de campo. Los principales resultados se sistematizan según las dimensiones estudiadas. En cuanto a la dimensión sociodemográfica, al detallar el personal que labora en el departamento financiero de la Universidad, se encontró que la mayoría pertenecen al sexo femenino. Otro dato para destacar es que existe un alto porcentaje que alcanzó el nivel de pregrado o tiene estudios técnicos; lo que refleja que están preparados profesionalmente. En cuanto a la dimensión clima organizacional, un bajo porcentaje considera que en ocasiones reciben apoyo de sus compañeros, de igual forma en la dimensión cultura organizacional, en cuanto a la valoración del conocimiento sobre la misión de la institución. En relación con la dimensión desempeño laboral percibido, un alto porcentaje de los empleados administrativos están predispuestos a realizar sus actividades sin supervisión. Como conclusión se destaca la percepción general de los participantes sobre el ambiente laboral que facilita el desempeño de sus actividades; sin embargo, existen indicadores como el interés por los aspectos familiares y la remuneración, que deben ser analizados, para adoptar iniciativas que favorezcan la integración y conciliación familia-trabajo; así como que existen aspectos de baja percepción: apoyo, retribución, interés de la institución por su bienestar y el de su familia y promoción de cursos de formación.
Corner Rules Method of Solving Transportation Problem
Authors: Aliu T.O. , Aderinto Y.O. , Issa K.
Published: July 2022

Several approaches have been advanced for solving transportation problems. The most prominent of them in various text being, North West Corner Rule(NWCR), Least Cost Method(LCM), and Vogel's Approximation Method(VAM). This paper considered three additional corner rules, which are North East Corner Rule(NECR), South West Corner Rule(SWCR) and South East Corner Rule(SECR). Algorithms ware provided for obtaining initial feasible solution to Transportation Problems. Three test examples were considered using the rules. The results revealed that the NECR and SWCR have equal result. While NWCR and SECR also produce the same result. NECR and SWCR however, better minimize transportation cost. The two methods are therefore recommended for use in any business organization requiring shipment of products.

The background of this research is due to unstable fluctuations in ROA, which shows that Islamic banks have not been able to maintain their stability, so research on profitability is needed. This study aims to determine the effect of NPF, FDR, on profitability with CAR as the Intervening variable for the case study of Islamic Commercial Banks for the period 2011-2020. The data collection method is by accessing data on financial ratios of each bank through the OJK website with purposive sampling as the sample used. The research method is quantitative research and uses WarpPLS 8.0 software. The findings of this study are to contribute to BUS regarding the factors that affect the profitability of Islamic Commercial Banks. From this study, it was found that the NPF and FDR variables had a significant negative effect on profitability, while the CAR had a significant positive effect. The NPF variable has a significant negative effect on CAR and the FDR variable has a significant positive effect. Based on the results of the path analysis test, CAR is able to mediate the effect of NPF on profitability, while for FDR, CAR is not able to mediate the relationship of FDR to profitability.

im: 1) To analyze the effectiveness of various treatment methods for stasis dermatitis. 2) To evaluate the effectiveness of various components of conservative therapy. Methods: 80 patients (52 women and 28 men) aged 43 to 82 years old with CEAP class C4a varicose veins of the lower extremities, complicated by stasis dermatitis, were enrolled in the study. The patients were divided into two groups of 40 people each, comparable in terms of the main clinical and anamnestic data. The patients of the first group underwent surgical elimination of pathological reflux followed by conservative therapy. In patients of the second group surgical intervention was postponed or contraindicated. Patients of the second group were randomly divided into two subgroups of 20 patients using a random number generator. Patients of the second group received various options of conservative therapy. Results: In the first group, 34 patients (85%) showed complete remission of stasis dermatitis in the control periods, in 6 patients (15%) the area decreased to 11mm2. In subgroup 2A, complete remission was observed in 13 patients (65%). In the rest (7) the affected area was 13.8±mm2. In subgroup 2B, complete remission was not observed. The affected area averaged 14.1±mm2. Conclusions: The best result in the treatment of stasis dermatitis was observed in the group that received surgical treatment followed by conservative therapy. In two subgroups receiving conservative therapy, the subgroup treated with venotonics, showed the best clinical result. The study confirms the need for an integrated approach to the treatment of chronic venous insufficiency complicated by stasis dermatitis.

The improvement of food preparation skills is beneficial for students with autism spectrum disorder (ASD) to strengthen their employment skills and improve their independent living ability. To enhance the skill development of ASD in food preparation with safe approaches, virtual reality (VR) was used in this study. A single-subject research method and multiple probes across the subject’s design were used. The participants were three 10th-grade students with ASD in a vocational high school. The training program of a food preparation curriculum was supplemented with sixty-minute VR sessions over 2 weeks, five times per week to collect data on the average procedural accuracy and completion time. The results indicate that procedural accuracy was improved and the effects were retained after the intervention. Although the average completion time was improved, the results of the simplified time-series analysis were not statistically significant.

The professional identity and teaching intention of normal university students who took a targeted training program for certain areas were analyzed by using a questionnaire survey and unstructured interviews. After graduation, the students who completed the targeted training program become teachers in rural areas. The students attended a university in Jiangsu Province, China and majord geography during 2016−2019. The results showed that the students had a certain degree of professional identity and gradually deepened their knowledge in college training. However, their professional identity and improvement degree were lower than those of students who did not take the targeted training program. 27.33% of the students with the targeted training program chose to work in the rural areas after the mandatory service period. In the process of the targeted training program, we proposed to improve the publicity of the program, optimize the training system, and raise the payment to ensure their continuous work even after the mandatory period.

: Undang-UndangÂ  Dasar Negara Â RepublikÂ  IndonesiaÂ  1945Â  sudah mengatur bentuk demokrasi sebaik mungkin pada Pasal 1 ayat (2) yang menjelaskan bahwa kedaulatan berada di tangan rakyat yang kemudian tentang pemilihan umum diatur dalam Pasal 22E. Hal ini juga diperjelas oleh JJ. Rousseau dalam bukunya Du Contract Social/Perjanjian Sosial yang menyatakan bahwa teori pembentukan negara berdasarkan adanya suatu kesepakatan rakyat (Setyo Nugroho, 2013: 248-230). Oleh dari itu rakyat bebas untuk memilih pemimpin dan wakilnya sendiri Â tanpa ada tekanan dari kelompok tertentu. Pemilihan Umum di tengah-tengah Covid-19 menjadi persoalan tersendiri yang sedang membutuhkan ruang khusus oleh karena itu dibutuhkan ruang untuk sosialisasi sesuai dengan situasi dan kondisi masa pandemi. Adanya sosialisasi terkait pemilihan dimasa pandemi akan menyadarkan masyarakat akan panduan protokol kesehatan terutama saat pemilihan umum dilaksanakan, dengan begitu masyarakat dapat memberikan hak suaranya dan tetap terhindar dari Covid-19

Quails breeding is easy to cultivate, can produce in a relatively short time and does not require a prominent location. Besides, male quail and rejected livestock are very well sold in the market. The obstacle to the development of quail so far is the high cost of concentrate feed with prices that tend to fluctuate so that the nutritional needs of quail have not been fulfilled, which in turn has an impact on production. Knowledge and skills of quail breeders are required in the management of quail rearing. Selection of seeds, feeding with good nutrition by utilizing feed ingredients from local sources is the right solution. This activity aims to increase knowledge of the PKK (group of women in the village) to develop quail farms. Activities are carried out in the form of program socialization and counseling. As a result, the activity has run smoothly; women of the PKK Pekik Nyaring can understand the management of quail breeding, especially the selection of seeds and the provision of quality feed with good nutrition.
