Published: January 2023

In order to improve air pressure utilization and working performance, the direct seed-metering device for rice was designed with spoiler blades embedded in the air cavity. The study was carried out using theoretical analysis and hydrodynamic methods to obtain the optimum structure of the spoiler blades. Taking the rotating speed of the air cavity, the negative pressure of the air cavity, and the filling height as the test factors, the multiple regression analysis and the response surface analysis were carried out to obtain the best working parameters of the seed-metering device with spoiler blades. The results showed that when the rotating speed of the air cavity was 23.56 r/min, the negative pressure of the air cavity was 4.97 kPa and the filling height was 12.82 cm, the qualified index was 95.21%, the missing index was 3.28% and the multiple index was 1.51%, which was the best seeding performance. Comparing the test with the seed-metering device without spoiler blades, the results showed that the installation of spoiler blades can improve the performance of the seed-metering device under the best working parameters. This study provide a reference for the design of direct seed-metering device for rice.

DIRECTION OF MINERALIZATION-SYNTHESIS PROCESSES OF ORGANIC MATTER IN LEACHED CHORNOZEM UNDER VARIOUS FERTILIZATION OF SPRING BARLEY
Authors: Volkohon V.V. , Dimova S.B. , Volkohon K.I.
Published: January 2023

Objective. To investigate the direction of mineralization-synthesis processes of organic matter in the soil during the cultivation of spring barley in different agrobackgrounds using new methodical solutions. Methods. Field experiment, gas chromatography (to determine the emission of nitrous oxide and carbon dioxide), statistical. Results. The study of the emission of nitrous oxide and carbon dioxide and subsequent calculations of the specific losses of N-N2O (g/kg С-СО2) depending on the fertilization systems and in comparison with the parameters in the “reference” soil (fallow) provide an opportunity to quickly determine the direction of mineralization-synthesis processes of organic matter in the soils of agrocenoses. Under the conditions of a stationary field experiment on leached chornozem during the cultivation of spring barley in crop rotation, it was shown that the use of mineral fertilization systems leads to the initiation of mineralization processes, the intensity of which increases with an increase in the rates of fertilizers. The application of mineral fertilizers against the background of the first year aftereffect of organic matter (5 t/ha of straw + 13 t/ha of the mass of intermediate lupine green manure) significantly improves the situation. At the same time, when using the lowest (N30P30K30) and medium (N60Р60К60) doses of mineral fertilizers in the experiment against the background of the aftereffect of organic fertilizers, the soil is characterized by the dominance of organic matter synthesis processes. The highest rate of fertilizers in the experiment (N90Р90К90), even if it is used against the background of the aftereffect of straw with lupine green manure biomass, leads to the activation of mineralization processes. Under the aftereffects of cattle manure, lupine green manure and their combination, including with mineral fertilizers, there is a slight predominance of mineralization activity over immobilization activity. Conclusion. The use of the gas chromatography in finding out the direction of mineralization-synthesis processes of organic matter makes it possible to quickly determine the ecological expediency of crop fertilization systems. To optimize the course of processes, it is advisable to combine the use of mineral fertilizers against the background of organic ones.

Clock Offset Estimation for Systems with Asymmetric Packet Delays
Authors: Ha Youngmok , Pak Eunji , Park Jongkil , Kim Taeho , Yoon Ji Won
Published: January 2023

This paper proposes a new clock offset estimation that mitigates unwanted link asymmetry for precise clock synchronization. The main contribution is to address the design issue of the IEEE 1588 standard precision time protocol (PTP), which estimates clock offset under the assumption that the delays of exchanged packets are symmetric. To mitigate the issue, we focus on the fact that PTP measures asymmetry variation through the derivatives of its timestamps with respect to the time step. By exploiting the measurement of the variation, the proposed approach defines the asymmetry in the form of a linear differential equation (LDE) and leverages the LDE to define and exclude asymmetry-induced errors. Additionally, we clearly derive the state transition of the asymmetry. Subsequently, we derive a novel state-space model from our approach. The model describes PTP clock offset estimation perfectly, allowing optimal clock offset estimation. We verify the theoretical validity of the proposed method with real data. Our approach improves PTP accuracy by more than thousand times and achieves an accuracy at the level of tens to hundreds of nanoseconds on an asymmetric communication link. Our approach realizes an accuracy comparable to that of PTPv2, without the cost of specialized hardware.

Authors: Senjaya Silvia , Yuliati Yayuk , Al-Uyun Dhia , Sita Kralawi
Published: January 2023

Previous research has shown that musculoskeletal disorders (MSDs) are one of the barriers for women to adopting tea-picking mechanization technology. Musculoskeletal disorders (MSDs) are defined as a group of injuries that affect the musculoskeletal system including nerves, tendons, muscles, and supporting structures. MSDs are also referred to as injuries due to overactivity or from using a device excessively. Some research results significantly show that gender greatly affects the level of risk of autonomic complaints and that women are more likely to show musculoskeletal symptoms than men. This study examines the comparison of musculoskeletal disorders due to the use of tea picking machines for male and female pickers.  Data collection on musculoskeletal disorders (MSDs) complaints was carried out using the Nordic Body Map instrument, in the form of an open questionnaire by interviewing mechanical tea pickers directly. From the data obtained, the average difference in scores for male mechanical tea pickers is 5.3 while the average difference in scores for female mechanical tea pickers is 9. This means that the average female mechanical tea pickers experience musculoskeletal complaints 70% more height than male mechanical tea pickers. MSDs complaints comparison between male and female tea pickers with NBM measurement is 5:9. In conclusion, female mechanical tea pickers suffer from MSDs almost twice as much as males. Considering that the majority of tea pickers are women, gender-responsive machine design interventions are needed.

Purpose: To observe the blood picture of patients with COVID 19 infections and to formulate future guidelines for management. Methods: This cross-sectional descriptive study was carried out among patients with COVID 19 infections who were admitted to one of the Covid-dedicated hospitals in Bangladesh from March-2020 to May-2020. Results: A total of 92 patients were included in this study. 53.3% were male and 46.7% were female. Most of the patient’s haemoglobin percentage was found below normal (53.3%), however, the total count of RBC, WBC and Platelet was found within the normal limits in most of the cases (64.1%,80.4% and 87% cases respectively). 75% of patients had high ESR levels. 50% of cases showed Neutrophilia and Lymphocytopenia in 43.5% cases. Although some cases show changes in Monocyte, Eosinophil and Basophil count they were not significant in number. Conclusions: A significant number of patient’s neutrophilia and lymphocytopenia. Blood parameter is an important tool for managing the COVID-19 patients. With or without co-morbidities maintaining normal blood levels is essential in COVID-19 patient management.

Background: Coronaviruses are large groups of viruses that cause illness in humans and animals. This virus has a higher degree of lethality than other endemic viruses Covid-19 diagnosis is based on viral detection, isolation, or serological changes. For cytopathic effects, sputum cytology is routinely performed for nearly all patients with chest symptoms. Objective: The study aimed to find Cytological change in sputum samples of COVID -19 patients in Shendi town. Materials and Methods: This study includes 45 subjects. Thirty were known as Covid 19 positive cases by PCR, and 15 were healthy subjects. Two sputum smears were collected from the study group then fixed in (95% Ethanol alcohol) and stained with Papanicolaou and Giemsa stains, then screening for any cytomorphological changes and microbes. Result: In cytology screening, intranuclear inclusion and inflammatory cells were observed in all sputum samples (100%) of patients infected with covid-19, other cytomorphological changes that appeared were nuclear atypia (96.6%), cytolysis (64.4%) and destructive change (fibrocytes) in (30%). None of the cytomorphological changes mentioned above were observed in the control sample. Co-infection with bacteria and fungi (aspergillus & Candida) exists in (66.6%) of Covid-19 patients. There was a statistically significant correlation between infection with covid-19 and the cytomorphological changes characterized in their sputum P. value was less than (0.05). Intranuclear inclusion in this study was a specific and sensitive indicator for Covid-19. There was no correlation between the period of infection and distractive change appearance or invasion with micro-organisms of the study group (P. value more than 0.05), But confections with microorganisms were statistically correlated to the age of the study group (P. value less than 0.05). Conclusion: Cellular changes and consistency of Sputum and saliva samples can provide inexpensive, rapid diagnostic, minimally invasive techniques for Covid-19, particularly in densely populated developing countries and areas.

The objective of this seminar is to present the levels of metals in commercially available imported and Ethiopian rice. The levels of thirteen metals (Ca, Mg, K, Na, Fe, Mn, Zn, Cu, Co, Ni, Cr, Cd and Pb) were determined in six varieties of raw rice collected from Addis Ababa supermarket, Fogera town and Amahara Regional Agricultural Research Institute and in one selected cooked rice by ﬂame atomic absorption spectrometry after digesting the powdered rice samples with HNO3, HClO4 and H2O2 mixture. The levels of metals found in the imported and Ethiopian rice, respectively, were in the ranges (mg/kg): Ca 75.8- 630, 205-427; Mg 90.6-150, 99.5-2250; K 1680-2150, 1100-3020; Na 70.6-78.6, 26.7-80.9; Fe 48.9-117, 41.3-113; Mn 4.1-15.5, 3.7-16.6; Zn 16.4-25.7, 15.6-140; Cu 2.7-4.9, 3.3-15; Co 12.6- 14.6, 8.8-10.4; Ni 2.5-75.1, 41.5-69.7; Cr 2.2-3.12, 2.32-4.82; Cd Comparison between levels of metals in the imported and Ethiopian rice showed significant differences for most of the metals. The results indicated that Ethiopian rice is comparatively rich in essential metals than imported one. A statistical analysis of variance (ANOVA) at 95% confidence level for metal determination indicated significant difference between the means of each variety of samples. Comparison between levels of metals in cooked and raw rice showed that the difference in the level is not significant.

Major limiting factors of wide consumption of cowpea in day today diet include poor digestibility and the presence of anti-nutritional factors. Whole and dehulled seeds of eight improved cowpea lines grown in N’Djamena and Bebedjia (Chad) were analysed for four antinutritional factors contents (total phenols, tannins, flavonoids, phytates) and antioxidant activity, in order to assess the variability and the effect of decortication. In each locality, the experimental design was a triplicated randomly complete block design. Standard methods were used to evaluate these biochemical traits. The results showed a wide variability among genotypes for these traits in whole and dehulled seeds. In average, the decortication reduced polyphenols, tannins, flavonoids and phytate contents by 72.3%, 64%, 48.6% and 30.1% respectively. The dehulling also reduced the antioxidant activity by 42.25%. Dehulling appeared as a proper processing method to reduce anti-nutritional factors and improve the bioavailability of nutrients, especially when cowpeas are used as food for infants and children.

Authors: Tsenova-Ilieva Irina , Karova Emilia
Published: January 2023

Remaining root dentin thickness plays a key role in the longevity of endodontically treated teeth. Purpose: The aim of this study was to compare the root canal wall thickness in the danger zones of mandibular incisors before and after their instrumentation with two different NiTi rotary systems by means of CBCT. Methodology: Thirty lower incisors of patients aged 45 – 55 years underwent primary endodontic treatment with two NiTi files systems: ProTaper Universal and WaveOne Gold. The changes of the root canal thickness in the danger zones of the incisors were investigated by two CBCT scans – one at the beginning of the experiment and the other after the shaping of the root canals. Results: Shaping of the root canals of lower incisors with the two NiTi systems significantly decreased the mesio-distal root dentin thickness in all root canal levels when compared with the baseline values (p≤0.001). NiTi files from both experimental groups removed substantially more root dentin in the coronal portion of the root than in the apical (p<0.05). The intergroup comparison between the two tested NiTi systems revealed no statistically significant difference in their performance at the three observation levels (p>0.05). Conclusions: Both NiTi systems performed equally and removed dentin more aggressively in the coronal portion of the root. Further clinical experiments are necessary to find the minimally invasive endodontic systems for an optimal preservation of root dentin in the danger zones of mandibular inciso

Published: January 2023

Renal vein thrombosis (RVT) in the post-partum period is rarely reported. It is majorly a complication of the hypercoagulability associated with both pregnancy and postpartum state. We report the case of a primiparous 19-year-old woman, who presented to the Emergency Department complaining of acute right flank pain. Doppler ultrasonography revealed thrombosis of the right renal vein with extension into the inferior vena cava (IVC). Contrast-enhanced abdominal computerized tomography (CT) confirmed the diagnosis. The outcome was favorable after anticoagulation therapy by Heparin was initiated. Practitioners need to be aware of the diagnosis of RVT. Imaging tests, especially contrast CT scans play a major role in the diagnosis and post-therapeutic assessment.
