Authors: . DHARMENDRA , CHANDRA SUBHASH , KUMAR AMIT , KUMAR NIRAJ
Published: April 2022

The zero till seed-cum-ferti-drill was assessed for field performance in sandy loam soil under tillage and no-tillage soil conditions at variable forward speed of tractor. With increase in forward speed of tractor, field capacity of the machine was in increasing order in all treatments, in tilth and un-tilth soil. Field efficiency of machine in tilth soil was initially increasing with tractor speed with maximum value 94.71% at 3.39 km/h. However, in un-tilth soil, it was highest (94.17%) at slowest speed i.e. 1.73 km/h and remained almost constant around 92% upon increase in tractor speed up to 4.32 km/h. The tractor wheel slip percentage started decreasing with increase in tractor speed and was in minimum range between 6.35-7.59% in tilth soil and between 16.03-15.55% in un-tilth soil in treatments at rated speed of the tractor between 3.62-4.77 km/h. Drive wheel skid in no-tillage condition of soil was found minimum at 5.69 km/h forward speed of tractor for zero till-seed-cum-ferti-drill and 188 the same was observed to be in decreasing order with increase in tractor forward speed. However, in tilth soil, drive wheel skid was remained in between 14.94%-19.05% with increase in tractor forward speed. Seeding efficiency of zero till-seed-cum-ferti-drill was observed to have been influenced by the drive wheel skid, and had direct as well as inverse co-relation with increase in tractor forward speed in un-tilth and tilth soil, respectively. Obviously, design characteristic of zero till-seed-cum-ferti-drill is better suited for its use in no-tillage soil condition to achieve higher seeding efficiency, field capacity and field efficiency.

Climate change is one of the most important worldwide issues talked among the scientists and researchers. The temperature and rainfall trends are analyzed for meteorological data of Junagadh station in Gujarat. India over approximately last three decades stretching between years 1971 to 2013. The long–term change in temperature and rainfall has been assessed by linear trend analysis. The increasing trend in mean monthly maximum temperature (MMAX) and total mean rainfall (TMRF) is confirmed by Mann-Kendall trend test. It is evident from that monthly mean temperature have increased significantly for all the months except the months of April and October for which a very weak decrease in mean maximum temperature is observed. This implies that at Junagadh, the highest increase in temperature occurred in November (0.0210C) during 1980-2011 period. The annual mean of monthly maximum temperatures (MMAX) observed an increasing trend having an annual decreasing of 0.0040C year during 1980-2011. It is evident TMRF have increased for the months April, May August and September whereas it shows decreasing trend in January, Feb, March, June, July, October, November and December. This implies that at Junagadh, the highest increase in TMRF occurs in August and increased by (0.029 mm) during the last 1980-2011. The highest decrease in TMRF occurs in June and decreased by (2.153mm) during the same period. The annual mean of total monthly rainfall observed a decreasing trend having an decrease of 0.249 mm/year during the last 31 years.

Published: April 2022

BACKGROUND

During the COVID-19 pandemic, several home-monitoring programs have described the success of reducing hospital admissions, but only a few studies investigated the experiences of patients and healthcare professionals.

OBJECTIVE

The objective of our study was to determine the patients’ and healthcare professionals’ perception on the usefulness of the COVID-box.

METHODS

Patients and healthcare professionals were asked to anonymously fill out multiple choice questionnaires. Themes for patients were sense of reassurance and safety, experience with teleconsultations, appreciation to stay at home and the instructions for the COVID-box, and themes for healthcare professionals who treated patients with the COVID-box were characteristics of the COVID-box, support service and the general point of view such as (estimated patient) satisfaction, meeting expectations and supporting this telemonitoring concept.

RESULTS

A total of 117 patients and 25 healthcare professionals filled out the questionnaires. Both groups scored high on all themes.

CONCLUSIONS

Positive experiences and satisfaction of involved users are key factors for a successful implementation of novel e-health solution. In our study, patients as well as healthcare professionals were highly satisfied with the use of the home-monitoring program, the COVID-box project. Remote home-monitoring may be an effective approach in case of increased demand for hospital care and high pressure on healthcare systems.
Direct-to-Consumer Genetic Testing in Social Media: Analysis of YouTube Users' Comments (Preprint)
Authors: Toussaint Philipp A , Renner Maximilian , Lins Sebastian , Thiebes Scott , Sunyaev Ali
Published: April 2022

BACKGROUND

With direct-to-consumer (DTC) genetic testing allowing consumers self-responsible access to novel information on their ancestry, traits, or health, consumers often turn to social media for assistance and discussion. While YouTube, the largest social media platform for videos, offers an abundance of DTC genetic testing-related videos, user discourse in the comments sections of these videos is largely unexplored.

OBJECTIVE

This study aims to address the lack of knowledge concerning user discourse in the comments sections of DTC genetic testing-related videos on YouTube by exploring topics discussed and users’ attitudes toward these videos.

METHODS

We employed a 3-step research approach. First, we collected metadata and comments of the 248 most viewed DTC genetic testing-related videos on YouTube. Second, we conducted topic modeling utilizing word frequency analysis, bi-gram analysis, and structural topic modeling to identify topics discussed in the comment sections of those videos. Last, we employed Bing (binary), NRC emotion, and 9-level sentiment analysis to identify users’ attitudes toward these DTC genetic testing-related videos, as expressed in the comments.

RESULTS

We collected 84,082 comments from the 248 most viewed DTC genetic testing-related YouTube videos. With the topic modeling, we identified six prevailing topics on (1) general genetic testing, (2) ancestry testing, (3) relationship testing, (4) health and trait testing, (5) ethical concerns, and (6) YouTube video reaction. Further, our sentiment analysis indicates strong positive emotions (anticipation, joy, surprise, and trust) and a neutral to positive attitude toward DTC genetic testing-related videos.

CONCLUSIONS

With this study, we demonstrate how to identify users' attitudes on DTC genetic testing by examining topics and opinions based on YouTube video comments. Shedding light on user discourse in social media, our findings suggest that users are highly interested in DTC genetic testing and related social media content. Nonetheless, with this novel market constantly evolving, service providers, content providers, or regulatory authorities may still need to adapt their services to users’ interests and desires.

Abstract: The medicine and vaccine require to store in the refrigerator the continuous provision of electrical energy is required so that their efficacy is not affected. This represents an important problem for rural areas where there is no continuous electrical energy. In this work, we design a solar energy system for refrigeration of cold storage medicines to be used in rural towns without giving continuous electrical. The system uses a thermoelectric refrigerator based on the Peltier effect, which produces a temperature difference when electrical power is provided to it. It will be shown that for a typical application for vaccine refrigeration, the required solar panel is about 100W peak connected to batteries with a storage capacity of 20Ah. The designed refrigeration system has a 14-liter volume capacity of vaccines at temperatures in the range of 14° to 15°C using a Peltier cell (TEC) that consumes 28 W at 12V.

Published: April 2022

Objectives: This study aimed to identify the characteristics of the heart rate variability (HRV) index in patients with burning mouth syndrome (BMS) and to evaluate the predictive value of HRV for Korean medical treatment responsiveness to tongue pain in BMS.Methods: Among BMS patients who visited the Oral Diseases Clinic of Kyung Hee University Korean Medicine Hospital from January 1, 2018, to May 31, 2021, we reviewed the clinical records of 217 women aged 50 years and over. HRV and unstimulated saliva flow rate (USFR) measurements were carried out, and all patients were asked to indicate their degree of tongue pain using the visual analog scale (VAS). The subjects were classified into subgroups according to the presence or absence of hyposalivation and VAS improvement, and each subgroup was compared using the HRV index. Logistic regression analysis was conducted to confirm whether cause–effect relationships were present between statistically significant values.Results: BMS patients had lower LF and HF than healthy people. Subgroup analysis demonstrated that there were some statistically significant differences in the HRV index according to salivation rate and degree of pain. In addition, as the LF/HF ratio increased, the pain improvement rate decreased after treatment.Conclusion: The autonomic nerve activity of BMS patients was lower than that of healthy people; however, autonomic balance was not impaired. In addition, tongue pain in BMS patients responded more favorably to Korean medical treatment when patients fell within a normal range of the LF/HF ratio, suggesting that autonomic imbalance could be used as one of the predictable factors in clinical practice.

The impact of directors’ liability insurance on board meeting attendance
Authors: Wang Yuwei , Yang Shang-Yin , Chen Chia-Wei
Published: April 2022

We study the relationship between directors’ liability insurance and board meeting attendance. We find that directors’ liability insurance and board meeting attendance are positively associated. This suggests that directors’ liability insurance may actually serve a governance role because an insurer definitely has incentives to thoroughly scrutinize the insured. As a result, director’s board meeting attendance rate increases because more monitoring of directors leads to more responsible behaviors of directors. With 98,524 yearly observations at the director level and 8,968 yearly observations at the firm level of listed firms in Taiwan during the period from 2008 to 2015, our empirical findings suggest that, on average, the board meeting attendance rate of insured firms is 2.9 percent higher than that of uninsured firms.

Authors: Hartanto Dadang , Hidayat Nasrullah
Published: April 2022

The purpose of this study was to determine community activities during the implementation of the activity restriction policy (Indonesian: Pemberlakuan Pembatasan Kegiatan Masyarakat, PPKM) during the COVID-19 pandemic in Medan city. The type of research method is a quantitative descriptive study using a survey design. The instrument used in this research is a questionnaire. The sampling technique was using accidental sampling so that the number of samples obtained was 790 people. The findings of this study are that the characteristics and economic activities of the people of Medan city during the implementation of PPKM are in the essential sector of as many as 423 respondents (53.6%). Quantitatively, this figure is high because it is above 50% when compared to the non-essential sector, which is less than 367 respondents (47.4%). PPKM officers need to ensure that employees who do not work in the office are for non-essential sector companies that run work from home (WFH) to avoid the spread of COVID-19. The selection of appropriate policies and public obedience to government policies related to activity restrictions can break the chain of the spread of COVID-19 in Medan city.
Quasi Steady-State Modeling and Analysis of Diffusion-Controlled Dissolution from Monodisperse Spheroidal Particles
Authors: Wang Yanxing , Wan Hui , Wei Tie , Nevares Dominick , Shu Fangjun
Published: April 2022

A quasi steady-model of the dissolution of a single prolate or oblate
spheroidal particle has been developed based on the exact solution of
the steady-state diffusion equation for mass transfer in an unconfined
media. With appropriate treatment of bulk concentration, the model can
predict the detailed dissolution process of a single particle in a
container of finite size. The dimensionless governing equations suggest
that the dissolution process is determined by three dimensionless
control parameters, initial solid particle concentration, particle
aspect ratio, and the product of specific volume of solid particles and
saturation concentration of the dissolved species. Using this model, the
dissolution process of felodipine particles in a broad range of space of
the three control parameters are analyzed and some characteristics are
identified. The effects of material properties indicated by the product
of specific volume and saturation concentration are also analyzed.

aortic valve. Methods: Between 2006-2016, a retrospective
analysis was performed on 24 patients that underwent open aortic valve
replacement surgery for a failed stentless aortic valve prosthesis at
Health Sciences North, Sudbury, Ontario, Canada. The primary outcome was
low mortality from cardiac related deaths after 5 years.
Results: All patients underwent an insertion of a Medtronic
Freestyle bioprosthesis implanted in the modified subcoronary technique
for their initial operation. The interval from the first operation to
the stentless redo surgery ranged from 6-13 years. Aortic valve
reoperation was performed for structural valve deterioration in 96% (n=
23) of the cases. Reoperations involved a removal of the stented valve
leaflets and stented valve-in-valve implantation in 20% (n= 5) of the
cases, with the remaining cases requiring complete removal of the
stentless prosthesis and aortic valve replacement. In those where a
complete removal of the stentless valve was possible (n=19), there was
no disruption of the native aortic root, and a 0% conversion to a
Bentall procedure. There was no intraoperative mortality. The 30-day and
10-year operative mortality was 4% and 16%, respectively.
Conclusions: Redo surgery for failing stentless valves can be
done with relatively low-risk and with acceptable long-term outcomes
without resorting to root replacement techniques.

Objective Patent ductus arteriosus (PDA) is an important cause
of morbidity and mortality, especially in very‐low‐birth‐weight infants.
The aim of the study is to report our single-center short-term results
of preterm patients who underwent patent ductus arteriosus ligation
through left anterior mini-thoracotomy . Methods Data of 27
preterm infants operated by the same surgeon who underwent PDA closure
with left anterior minithoracotomy technique between November 2020 and
January 2022 at a single instution were reviewed. The patients were
divided into two groups according to their weight at the time of
surgery. Data on early postoperative outcomes and survival rates after
discharge were collected. Results Twenty-seven patients with a
mean (±SD) gestational age of 25.8 (±2.0) weeks and a mean birth weight
of 1027 (±423) g were operated using left anterior mini-thoracotomy
technique. The lowest body weight was 480 g. Complications such as
bleeding, abnormal healing of incision or pneumothorax were not seen.
There were 8 mortalities after the operation (29,6 %). There was no
internal thoracic artery injury or no need for conversion to thoracotomy
or sternotomy. there were 6 (22%) deaths in the postoperative first 30
days and 4 (14,8%) deaths between the postoperative first month and
first year. The cause of the deaths were sepsis, NEC, hydrops fetalis,
hepatoblastoma and intracranial bleeding. Left diaphragmatic elevation
developed in 1 patient, and plication was performed. There was no
statistically significant difference in the rates of morbidity, and
complication between the groups. Conclusions PDA closure with
the left anterior mini-thoracotomy method is advantageous in terms of
reducing damage to the already congested lung, shortening the
hypothermia time of the baby by shortening the procedure time, and has
good cosmetic results, especially in very low birth weight preterm
babies.

Published: April 2022

Cardiac tumors are rare, which were found in only 0.001%–0.300% of
cases in a relatively recently reported autopsy series. Among cardiac
tumors, primary hemangioma accounted for approximately 2.8% of all
primary resected tumors, indicating that this is a particularly rare
benign neoplasm. We presented a patient with a 5×3×2 cm cavernous
hemangioma arising from the right atrial roof, occupying the atrial
septum and inseparable from the aortic root. We successfully performed
complete surgical tumor resection and reconstruction of the right atrium
and atrial septum using a bovine pericardial patch for a huge cavernous
cardiac hemangioma filling the cardiac atrium.

Published: April 2022

As a vital element of climate change, elevated temperature resulted from
global warming presents new challenges to natural and agricultural
sustainability such as ecological disease management. Mitochondria
regulate energy production of cells in responding to environmental
fluctuation but studying their contribution to the thermal adaptation of
species is limited. This knowledge is needed to predict future disease
epidemiology for ecology conservation and food security. Spatial
distributions of mitochondrial genome (mtDNA) in 405 Phytophthora
infestans isolates originating from 15 locations were characterized.
mtDNA contribution to thermal adaptation was evaluated by comparative
analysis of mtDNA frequency and intrinsic growth rate, relative
population differentiation in nuclear and mtDNA and associations of
mtDNA distribution in with local geography climate conditions.
Significant variation in frequency, intrinsic growth rate and spatial
distribution was detected in mtDNA. Population differentiation in mtDNA
was significantly higher than that in nuclear genome, and spatial
distribution of mtDNA was strongly associated with local climatic
conditions and geographic parameters particularly air temperature,
suggesting natural selection caused by local temperature is the main
driver of the adaptation. Dominant mtDNA grew faster than the less
frequent mtDNA. Our results provide useful insight into the evolution of
pathogens under global warming. Given its important role in biological
functions and adaptation to local air temperature, mtDNA intervention
has become an increasing necessity in future disease management. To
secure ecological integrity and food production under global warming,
synergistic study in the interactive effect of changing temperature on
various components of biological and ecological functions of
mitochondria in an evolutionary frame is urgently needed.

Second degree linear forms and semiclassical forms of class one: A case study
Authors: Ben Salah , Marcellán Francisco , Khalfallah Mohamed
Published: April 2022

Based on their second degree character, in this contribution we study new
characterizations of families of symmetric and quasi-symmetric semiclassical
linear forms of class one. In fact, by using the Stieltjes function and the
moments of those forms, we give necessary and sufficient conditions for a
regular form to be at the same time of the second degree, symmetric (resp.
quasi-symmetric) and semiclassical of class one. We focus our attention on
the link between these forms and the Jacobi forms Tp,q = J(p-1/2, q-1/2), p,q ? Z, p+q ? 0. All of them are rational transformations of the
first kind Chebychev form T = J (-1/2,-1/2). Finally, we study a family of
second degree linear forms which are semiclassical of class one and are not
included in the above families.

Authors: Li Zuquan
Published: April 2022

Let PR(X) denote the hyperspace of nonempty finite subsets of a topological
space X with the Pixley-Roy topology. In this paper, motivated by [4], we
introduced cf-covers and rcf-covers of X to establish the R-selective
separability and the M-selective separability in PR(X) under the Pixley-Roy
topology. We proved that the following statements are equivalent for a space
X: (1) PR(X) is R-separable (resp., M-separable); (2) X satisfies S1(Crcf, Crcf) (resp., Sfin(Crcf,Crcf)); (3) X is countable and each co-finite
subset of X satisfies S1(Ccf, Ccf) (resp.,Sfin(Ccf,Ccf)); (4)Xis
countable and PR(X) has countable strong fan tightness (resp., PR(X) has
countable fan tightness).

Authors: Magdalena Peterlin  , Christian Andergassen  , Daniel Pichler
Published: April 2022

Die Regulierung des vegetativen Wachstums im Apfelanbau ist eine wichtige Maßnahme, um den Ertrag konstant zu halten und die Fruchtqualität zu fördern. In zwei verschiedenen Versuchen wurden am Versuchszentrum Laimburg unterschiedliche Methoden zur Wachstumsregulierung untersucht. Unter anderem wurde das Handelsprodukt Paclot New mit dem Wirkstoff Paclobutrazol, früher bekannt unter dem Handelsnamen Cultar getestet. Trotz positiver Ergebnisse bei älteren Versuchen, konnte bei beiden Versuchen kein wachstumsregulierender Effekt von Paclobutrazol festgestellt werden. Behandlungen mit dem Wirkstoff Prohexadion-Ca wiesen hingegen eine signifikante Reduktion des Triebwachstums im Vergleich zur unbehandelten Kontrolle auf. Der Wurzelschnitt und Behandlungen mit Paclobutrazol verkleinerten die Fruchtgröße in machen Versuchsjahren signifikant. Rückstände von Paclobutrazol konnten während des Versuchs, außer in den Blättern und Trieben und ein Jahr im Boden nicht festgestellt werden.
Effect of Fluid Contact Angle of Oil-wet Ceramic Fracture Proppant on the Water Flow from Sandstones to Proppant Packs
Authors: B Guo
Published: April 2022

Ceramic fracture proppants are extensively used for enhancing oil and gas well productivity in low-permeability reservoirs. Previous work reported attracting-oil-repelling-water (AORW) property of oil-wet proppants at the faces of fractures. Because of lack of method for measuring contact angle of proppant packs, the terms water-wet proppant and oil-wet proppant were defined on the basis of observations of liquid droplets on the surfaces of proppant packs without quantitative measurement. An innovative method was developed in this study to determine the contact angles of fracture proppant packs. The effect of oil contact angle of oil-wet fracture proppant pack on the competing water/oil flow from sandstone cores to the packs was investigated. It was found that, for a given fracture proppant pack, the sum of the water contact angle and oil contact angle measured in the liquid-air-solid systems is less than 180 degrees, i.e., the two angles are not supplementary. This is believed due to the weak wetting capacity of air to the solid surfaces in the liquid-air-solid systems. Both water and oil contact angles should be considered in the classification of wettability of proppant packs. Fracture proppant packs with water contact angles greater than 90 degrees and oil contact angles significantly less than 90 degrees can be considered as oil-wet proppants. Reducing oil contact angles of oil-wet proppants can increase capillary force, promote oil imbibition into the proppant packs, and thus improve the AORW performance of proppants. Fracture proppant packs with water contact angles less than 90 degrees and oil contact angles less than 90 degrees may be considered as mixed-wet proppants. Their AORW performance should be tested in laboratories before they are considered for well fracturing operations.
Gibbs Free Energy Implications of Electric Double Layer for Wettability Trend in Geologic Carbon Storage
Authors: A Miadonye
Published: April 2022

In this paper, we demonstrated the theoretical relationship between Gibbs free energy of the electric double layer and aqueous solution pH. The basis for our theoretical derivation is the fundamental electrochemical equation of Nernst and the Gouy Chapman theory of the electric double layer. In the thermodynamic sense, the partial derivative of Gibbs free energy with regard to interface/surface area is shown to directly linked to interfacial or surface energy, where the former is pH dependent. Accordingly, our theoretical derivation has permitted the interpretation of wettability trends in saline aquifers under geological carbon storage.

Published: April 2022

A modeling problem of the process of liquid multi component decontamination by a spatial filter is considered, it takes into account the reverse influence of decisive factors (contamination concentrations of liquid and sediment) on characteristics (coefficient of porosity, diffusion) of the medium and gives us the possibility to determine small mass transfer coefficient under the conditions of prevailing of convective constituents over diffusive ones. An algorithm of the solution of the corresponding nonlinear singular disturbed inverse problem of "convection-diffusion mass transfer" type is suggested.

Published: April 2022

A model for interaction of polarized light with inhomogeneously strained non-magnetizable dielectric solid is considered in the paper. The model establishes ray photoelasticity integrals connecting distributions of strain tensor components on any direction on the body volume with measurable optical parameters of polarized light beam propagating in this direction. The model can be used for developing mathematical methods for polarized-optical computational tomography of stress-strained states of dielectric solids.

Published: April 2022

A two-mass system is investigated. It is considered as a set of dynamical subsystems. To switch between these subsystems, fuzzy controller is synthesised. The research is held for the case when one subsystem is unstable having one root in the right-hand side of the plane. The stability of the overall system, depending on the stability of the subsystems of which it is composed is examined. For this, a 3D hodograph is used. Quality indexes of the system with unstable subsystem are calculated. The case when the system operates under external perturbations is consider. The influence of perturbations value and controller parameters of the transient of the system is investigated. The gain in the case of usage of the unstable subsystem is pointed out.
