Keeping Telehealth an Equalizer in the Age of COVID (Preprint)
Authors: Marcin James
Published: July 2022

BACKGROUND

Telehealth has historically been used to increase access to care for marginalized populations living in rural and underserved communities and those that require frequent medical care. Video visits have been used to address distance barriers for routine and specialty care and remote patient monitoring has been used to help those with chronic medical conditions. However, following the COVID pandemic, telehealth is standard and less likely to be used by populations that could benefit most from its use.

OBJECTIVE

The objective of this review is to evaluate whether telemedicine use is lower among patients without insurance, racial/ethnic minorities, and non-English speaking patients.

METHODS

From reviews of the literature and USA data, comparisons of telehealth use between different populations were conducted. Utilization rates were compared between racial/ethnic groups (Black-Asian-White and Hispanic-Non-Hispanic) and among different telehealth use cases: on-demand direct to consumer care; scheduled ambulatory video visits; and remote patient monitoring applications.

RESULTS

Among telehealth users in the USA, the highest share of visits that utilized video services occurred among young adults ages 18 to 24 (72.5%), those earning at least $100,000 (68.8%), those with private insurance (65.9%), and White individuals (61.9%). Video telehealth rates were lowest among those without a high school diploma (38.1%), adults ages 65 and older (43.5%), and Hispanic (50.7%), Asian (51.3%) and Black individuals (53.6%).

CONCLUSIONS

Telehealth use increased dramatically during the COVID-19 pandemic, but research suggests that access to telehealth was not equitable across different population subgroups. Following the pandemic, the use of telehealth has gone from a tool that was used to primarily address barriers in access among minority populations to a model of care that serves those that are better insured, English speaking, and White. Interventions to address inequities involve payment policies, ambulatory operations, and investments in making telehealth more accessible by underserved populations.
Relationship between soil management and rainfall erosion: A case study in the Guajará-Mirim river watershed, Vigia - Pará
Authors: Goes Jaime Carvalho , Oliveira Eder Silva de
Published: July 2022

This study aims to evaluate the relationship between soil management and its loss by rainfall erosion in the watershed of the Guajará-Mirim river. The methodology used was essentially carried out by remote sensing, literature review and the application of the Universal Soil Loss Equation (USLE), with the geoprocessing of matrix and vector files in the QGIS software. The results show that, in relation to soil management in the study region, considering that it is a plain and that there were no measures to control soil erosion, its loss by rainwater transport is aggravated the greater the exposure of the soil, that is, the removal of vegetation and the revolving soil horizons. This assertion is evidenced by the greater soil loss in the areas mapped for sand extraction and deforestation by calculating the Universal Soil Loss Equation.
KANT ON PHILOSOPHICAL EDUCATION IN THE AGE OF CRITIQUE
Authors: Prelević Duško
Published: July 2022

In Announcement of the Programme of his Lectures for the Winter Semester 1765‒1766, Immanuel Kant outlined his views of how philosophical education ought to be conducted. According to him, the method of instruction in philosophy should be zetetic, which means that students should first learn to philosophize rather than (as they typically expect) to learn philosophy, that is, that learning how to think for oneself ought to be preferred over learning particular philosophical systems. Kant argued for this view by claiming that philosophy at his time was not yet a complete discipline, and accordingly, that there was no philosophical book which might be said to contain definite solutions to the main philosophical problems.Given that the claims above had been stated in 1765, and that later on (in the 1780s and 1790s in particular) Kant thought that he had practically solved (or resolved) all the important philosophical questions, it is interesting to see whether his views of philosophical education remained the same, even more so because at that time he still claimed (for example, in Critique of Pure Reason and according to some transcriptions of his lectures) that his age was the age of critique and therefore it had to be seen what will come of it. I argue in this paper that there are good reasons to believe that Kant's aforementioned claims are compatible and that the continuity of his thoughts on these things can be preserved.
O desmonte da estatalidade brasileira no caso da política pública de saneamento e a falácia da regionalização como vetor de desenvolvimento regional
Authors: Silva José Irivaldo Alves Oliveira , Feitosa Maria Luiza Pereira de Alencar Mayer , Soares Aendria de Souza do Carmo Mota
Published: July 2022

A nova normativa do saneamento básico no Brasil, Lei nº 14.026/2020, abriu caminho para um modelo mais agressivo de inserção do capital privado no chamado “negócio do saneamento”, ao alterar a forma de organização do serviço nos estados, pela imposição da regionalização em blocos de municípios, e ao modificar as regras contratuais de concessão praticadas até então com as companhias estatais de água e esgoto. Neste ensaio, os autores analisam as alterações legais pelo viés da consideração preliminar de que, nesse setor, arranjos de poder multiescalares e multiníveis, visíveis ou não, suplantam os interesses locais e distorcem a realidade por meio de narrativas falaciosas. O problema de pesquisa é investigar se, de acordo com o novo marco, água e saneamento são considerados direitos humanos fundamentais ou simples serviços regulados, questionando a regionalização adotada como instrumento de promoção de desenvolvimento regional ou como mero pretexto para a privatização do setor. A opção metodológica abrange análises de tipo conjuntural, histórica, crítica e comparativa da realidade nacional, para verificar, ao fim e ao cabo, que a lei promove grave mudança na correlação de forças econômicas públicas e privadas no setor de saneamento, no âmbito dos estados federados, com impacto conceitual no papel do Banco Nacional de Desenvolvimento (BNDES), responsável pela modelagem do processo, que, sem problematização das consequências, como risco de aumento da tarifa, falta de acesso aos serviços pelas camadas mais vulneráveis da população e privatização ilegal de um monopólio natural em sua essência, se transforma de banco de fomento em leiloeiro facilitador da venda.

Objectives: The purpose of this study is investigating curcumin role in mood alterations in male rats after spinal cord injury through focusing on the involvement of NLRP3 inflammasome.

Methods: Fourteen  adualt male Wistar rats (220–250 g) were divided to five animal groups (n = 8 per group): Control: healthy animals which  received normal saline for 14 days; spinal cord injury: spinal cord injury-induced animals which received normal saline for 14 days; spinal cord injury + curcumin (20, 40, and 80 mg/kg/ i.p): spinal cord injury-induced animals treated with 3 doses of curcumin for 14 days. To assess the mood of animals, the elevated plus maze test, forced swimming test, tail suspension test, and open field test were performed. Graph-pad prism software was used for data analysis. Statistical analysis was done by one-way ANOVA with Tukey’s post hoc test. P < 0.05 was statistically significant.

Results: Treatment with curcumin with two doses of 40 and 80 mg/kg increased open arm time and decreased close arm time as compared to the spinal cord injury group. The administration of curcumin (40 mg/kg and 80 mg/kg) enhanced the altered behaviors. Spinal cord injury caused an increase in the protein levels NLRP3, ASC and Casp1 in the hippocampus of animals as compared to the sham group. Curcumin regulated the protein levels of NLRP3, ASC and Casp1 in the hippocampus of animals.

Conclusion: Depression is prevalent in person with spinal cord injury and our findings indicated that curcumin appears to constitute a suitable agent to reduce neuroinflammation and through it, relieve a depressive-like state.

Karakteristik backpacker nusantara dalam komunitas “backpacker international”
Authors: Susanti Luh Eka , Supartini Ni Luh , Semara I Made Trisna
Published: July 2022

In society’s perception, backpackers are generally travelers who choose to travel for long periods of time, at low costs using public transportation and relatively cheap accommodation. Usually, backpackers come from the lower middle class because they want to travel that is cost-effective but rich in experience. In addition, most of these backpackers are students / students with an age range between 25 - 35 years. Over time and an era that has changed the human mindset, a significant shift has begun to occur, especially for the tourist actor himself as a backpacker. Although the above characteristics are still a strong concept for a backpacker, there are a number of things that are starting to shift. Some of these things are 1) backpackers do not always come from the lower middle class, and 2) a shift in the age of the backpacker criteria (tourists over 35 years old choose to be backpackers). Therefore, it is interesting to study from this phenomenon is the shift in people's perceptions of a backpacker where now backpackers also come from the upper middle class and have an age above 35 years. The data is taken from 35 backpackers who are members of the “Backpacker International” community, which consists of Indonesian backpackers whose travel destinations are to other countries (mostly in Europe). This research is an ethnographic study with a qualitative descriptive approach.

Published: July 2022

This paper aims to analyze the governance and regulation of local working requirement (LWR) and importation of pharmaceutical products in Indonesia. Based on the theoretical perspectives of Cottier and Panizzon (2004) and Champ and Attaran (2002), this study aims to analyze the important role of patents through LWR and importation, both directly or indirectly to facilitate the transfer of technology and to stimulate technology transfer with the availability of technology information through patent documents. The research was conducted by using a qualitative descriptive-analytical method. A doctrinal approach was used in this study in the context of reviewing the laws and regulations in the field of patents, the World Trade Organization (WTO) Agreement on Trade-Related Aspects of Intellectual Property Rights (hereinafter TRIPS Agreement), health law, and its derivative regulations. The theory used in this study is about the politics of patent law which focuses on the national interest to pursue local production of patented inventions. The results showed that LWR, pharmaceutical importations provisions, and intellectual property rights law policies as a whole in Indonesia need to be harmonized and integrated with policies on technology transfer, industrial development, trade, and investment. The results underscore the main way in which LWR can contribute directly to the transfer of technology in developing countries.
A superstructure-based approach for integrating work-heat within hydrogen allocation network
Authors: Hong Huiquan , Zhuang Yu , Zhang Lei , Xing Yafeng , Liu Linlin , Du Jian
Published: July 2022

The use of hydrogen gases has expanded significantly in chemical
industry due to its contribution to the decarbonization. The
temperatures and pressures of hydrogen gases should be managed to
satisfy the different hydrogen consumers that leads to considerable
energy consumption. Such a serious challenge highlights the importance
of work-heat integration for energy savings of hydrogen networks.
Towards this end, a superstructure-based method is proposed for the
work-heat integration specific to hydrogen allocation network, wherein
the complex thermophysical properties of hydrogen are represented via an
accurate surrogate model derived from the data of process simulation. To
perform the optimal design of the system, a mixed integer nonlinear
programming model is formulated to reflect all considered work-heat
interactive relationship and constraints in hydrogen networks. Two
examples are studied. 10.8% reduction in the net power consumption and
44.3% decrease in the total annual cost have shown the superiority of
the proposed method.

We investigate the global existence of small data solutions to the
Cauchy problem for the semi-linear time fractional σ-evolution equation
models with nonlinearity of derivative type and memory. Based on the Lr
− Lq estimates obtained in linear problem, and combined with the global
iteration method, the global existence of small data solutions is proved
under certain conditions of power p. Furthermore, we find that in the
low-dimensional case, the limit of our conclusion can match the critical
exponent in classical results.
Hot Exciton Effect in Photoluminescence of Monolayer Transition Metal Dichalcogenide
Authors: Xiao Ke , Duan Ruihuan , Liu Zheng , Watanabe Kenji , Taniguchi Takashi , Yao Wang , Cui Xiaodong
Published: July 2022

Hot excitons are usually neglected in optical spectroscopy in 2D
semiconductors for the sake of momentum conservation, as the majority of
hot excitons are out of light cones. In this letter, we elaborate the
contribution of hot excitons to optical properties of monolayer MoSe2
with photoluminescence (PL) and photoluminescence excitation (PLE)
spectroscopy. With the excitation-intensity-dependent PL,
temperature-dependent PL and PLE experiments combined with the
simulations, we experimentally distinguish the influences of the exciton
temperature and the lattice temperature in the PL spectrum. It is
concluded that the acoustic phonon assisted photoluminescence accounts
for the non-Lorentzian high energy tail in the PL spectrum and the hot
exciton effect is significant to linear optical properties of TMDs.
Besides, the effective exciton temperature is found to be several tens
of Kelvin higher than the lattice temperature at non-resonant optical
excitation. It indicates that the exciton temperature needs to be
carefully taken into account when considering the exciton related
quantum phase phenomena such as exciton condensation. It is
experimentally demonstrated that the effective exciton temperature can
be tuned by excitation energy.
Optimal control strategies for the reliable and competitive mathematical analysis of Covid-19 pandemic model

Published: July 2022

To understand dynamics of the COVID-19 disease realistically, a new
SEIAPHR model has been proposed in this article where the infectious
individuals have been categorized as symptomatic, asymptomatic and
super-spreaders. The model has been investigated for existence of a
unique solution. To measure the contagiousness of COVID-19, reproduction
number R is also computed using next generation matrix
method. It is shown that model is locally stable at disease free
equilibrium point when R <1 and unstable for
R >1. The model has been analyzed for
global stability at both of the disease free and endemic equilibrium
points. Sensitivity analysis is also included to examine the effect of
parameters of the model on reproduction number R.
Couple of optimal control problems have been designed to study the
effect of control strategies for disease control and eradication from
the society. Numerical results show that the adopted control approaches
are much effective in reducing new infections.

$$\|u^1\|_{L^{r,s}}+\|u^2\|_{L^{r,s}}+\|\nabla
d\|_{L^{r,s}}\leq
\infty,
\qquad\frac{3}{r}+\frac{2}{s}\leq1.$$

comonents of $u$ and $\nabla d$ belong to
$L^{6,\infty}$ and $u$ belongs to
$L^{2+\delta}$
($\delta>0$).
Lipidomic remodeling of contrasting maize (Zea mays L.) hybrids under repeated drought
Authors: Kränzlein Markus , Schmöckel Sandra , Geilfus Christoph-Martin , Schulze Waltraud , Altenbuchinger Michael , Hrenn Holger , Roessner Ute , Zörb Christian
Published: July 2022

The role of recovery after drought has been proposed to play a more
prominent role during the whole drought-adaption process than previously
thought. Two maize hybrids with comparable growth but contrasting
physiological responses were investigated using physiological, metabolic
and lipidomic tools to understand the plants’ strategies of lipid
remodeling in response to repeated drought stimuli. Profound differences
in adaptation between hybrids were discovered during the recovery phase
of lipidomic adaptation, which likely gave rise to different degrees of
sensitivity to the subsequent drought event. These differences in
adaptation are visible in galactolipid metabolism and fatty acid
saturation patterns during recovery and may lead to a lipidomic
dysregulation in the sensitive maize hybrid. Moreover, the more drought
tolerant hybrid displays more changes of metabolite and lipid abundance
with higher number of differences within individual lipids, despite of a
lower physiological response, while the responses in the sensitive
hybrid are higher in magnitude, but lower in significance on the level
of individual lipids and metabolites. This study suggests that lipid
remodeling during recovery plays a key role in the drought response of
plants.
A cubic B-spline finite element method for a class of fourth order nonlinear differential equation with variable coefficient
Authors: Qin Dandan , Huang Wenzhu
Published: July 2022

In this paper, the cubic B-spline element method is proposed for a class
of fourth order nonlinear parabolic problem with variable coefficient.
We prove the boundness of the approximate solutions of the semi-discrete
and fully discrete finite element schemes. The boundness is the basis of
error analysis of nonlinear parabolic problem, especially in the case of
fourth order term with variable coefficient. The error estimates are
discussed by constructing the energy functional in $L^2$ norm and
$H^2$ norm. Numerical results confirm our results of theoretical
analysis.
Influence of calcination temperature on structure and multiferroic properties of barium ferrite ceramics

Published: July 2022

In this paper, barium ferrite powders were synthesized by sol-gel method, calcined at different temperatures,
and on this basis the corresponding ceramics were prepared. The effects of calcination temperature on the
structure, magnetic, dielectric and multiferroic properties of BaFe12O19 ceramics were studied. XRD results
confirmed similarity between powders and ceramics, where dominant phase is BaFe12O19 and a small amount
of an apparent BaFe2O4 impurity phase was formed at lower calcination temperature. The impurity BaFe2O4
phase is the main reason for decreasing powder magnetization. The maximum dielectric constant of 100
(at 10 kHz) and maximum remanent polarization, remanent magnetization and saturation magnetization of
0.46 ?C/cm2, 47.37 emu/g and 79.96 emu/g, respectively, were obtained in the barium ferrite ceramics prepared
from the powder calcined at 1100?C. This research could be the basis for the study of single-phase multiferroic
materials and the development of multi-order electronic devices.
Fabrication of ceramics using photosensitive slurries: A comparison between UV-casting replication and vat photopolymerization 3D printing
Authors: de Camargo Italo , Lovo João Fiore Parreira , Erbereli Rogério , Bock Eduardo , Fortulan Carlos
Published: July 2022

The development of photosensitive ceramic slurries for vat
photopolymerization (stereolithography or digital light processing) has
received much effort in recent years. However, many of these ceramic
suspensions have high viscosity and they are suitable for use only on
equipment, specialized in ceramic additive manufacturing. In this work,
ceramic manufacturing using photocurable slurries was tested in a low-cost
vat photopolymerization printer and in silicone moulds for UV-casting
replication, with the latter approach still scarcely explored in the
literature. Both processes were able to produce ceramic parts. The
UV-casting replication was able to work with more viscous photocurable
ceramic slurries and proved more suitable for the manufacturing of ceramic
parts with larger cross-sections, providing pieces with improved flexural
strength to those produced by additive manufacturing. This work presents the
possibility of UV-casting photosensitive slurries to manufacture ceramics,
an approach that could be easily adopted without high equipment costs.

Published: July 2022

In this work g-C3N4/CuS composite film was prepared by successive ion layer
adsorption and reaction (SILAR) method and used as the counter electrode in
quantum dot sensitized solar cell (QDSSCs). To configure the cell, CdSe and
CdS quantum dots acted as sensitizers on the photoanode side, polysulphide
was used as the electrolyte and copper sulphide was deposited into the
g-C3N4 film structure on the counter electrode side. Scanning electron
microscope and X-ray diffraction were used to characterize the morphology

Salmo trutta is a key species of headwater streams that is able to influence the structure of these ecosystems through predation. Populations of this species are being threatened by climate change and hydrological alteration. In order to understand how their disappearance would affect the ecosystem structure of headwater streams, we used cage experiments to analyse different biofilm and macroinvertebrate structural parameters and the biodiversity of their communities under different trout densities. Due to a heavy rain event, our experiment was destroyed on the 10th day, but the role of trout as stream ecosystemic structure drivers was observed, as multiple parameters were modulated by their presence or absence. In the high-density treatments, a significant reduction in the biomass of macroinvertebrate families that fed on biofilms was observed due to direct predation on them, which caused the biofilms to be more autotrophic. A decrease in brown trout population densities could cause cascading trophic effects on the ecosystem structure of headwater streams
Promoting millet, an underutilized crop. A review of food-based approach in combating micronutrient deficiency
Authors: ILO Jumoke , Famakinwa Abiodun
Published: July 2022

Malnutrition of micronutrients is a global problem that is more serious than hunger and has lasting consequences for societies. This study reviews existing interventions, where traditional grains are being promoted to establish their importance and promote their use as food. It examines a sample of existing literature, highlights, some key takeaways, and identifies knowledge gaps and research objectives in order to solve the global problem of micronutrient deficiency. A more recent method is to use revolutionary food processing processes to produce micronutrient-rich meals using underutilized or local food crops like millet, which can prevent numerous micronutrient deficits at the same time without the risk of antagonistic interactions or nutrient loss.

An atypical case of VITT was described resulting from a vaccination schedule where the third booster with ChAdOx1 nCoV-19 (AstraZeneca) was administered. The patient received a complete vaccination schedule with two doses of Pfizer–BioNTech (BNT162b2) without any complications before the third dose. However, the patient has developed an infrequent yet extreme prothrombotic; hypercoagulable state caused by platelet-activating anti-platelet factor 4 (PF4) antibodies. This phenomenon is typically triggered by the proximate administration of an adenoviral vector vaccine against COVID-19. The patient’s symptoms began ten days after taking the third dose of the ChAdOx1 nCoV-19 vaccine (AstraZeneca). His main complaints when hospitalized were severe headaches and right abdominal pain. The blood tests and MRI scan imaging findings were very characteristic of VITT, and a rare cerebral venous sinus thrombosis was found. Also, a markedly elevated D-dimer and strong positive PF4-dependent enzyme- immunoassay test results were documented. Due to discerning clinical suspicion, this patient was rapidly treated with immunoglobulin infusion for two days and oral steroids for three days. Subsequently, he was anticoagulated with the new oral anticoagulant edoxaban after platelet numbers recovery. In a few days, platelets normalized, and D-dimer levels decreased, while anti- PF4-dependent enzyme-immunoassay test results showed a slow decline. He was discharged taking oral edoxaban without any squeal.
Pengaruh Penambahan Mikroorganisme Lokal (MOL) Dari Nasi Basi Terhadap Pupuk Organik Cair Cangkang Telur

Published: July 2022

Sejak zaman dahulu sampai sekarang penggunaan pupuk masih kita jumpai, namun seiring berjalan nya waktu para petani lebih memilih menggunakan pupuk anorganik daripada pupuk organik. Hal tersebut lama-kelamaan akan menimbulkan efek negatif terhadap tanah serta tanaman. Penggunaan pupuk organik adalah salah satu cara menangani pencemaran tanah. Pupuk organik dapat berwujud cairan atau padatan dan berasal dari bahan organik, salah satu bahan organik yang dapat dijadikan pupuk organik adalah cangkang telur. Kandungan kalsium karbonat dalam cangkang telur dapat menetralkan pH tanah, sehingga banyak digunakan di bidang pertanian. Adapun pupuk organik lainnya yaitu Mikroorganisme Lokal (MOL). MOL merupakan mikroorganisasi yang terbuat dari bahan-bahan alami sebagai media berkembangnya mikroorganisme yang berfungsi untuk starter dalam pembuatan pupuk organik. Salah satu bahan yang biasa dipakai membuat MOL adalah nasi yang sudah tidak terpakai. Tujuan penelitian ini adalah untuk mengetahui bagaimana pengaruh penambahan MOL terhadap kualitas pupuk organik cair berbahan dasar cangkang telur. Metode pembuatan pupuk organik adalah dengan cara fermentasi. Berdasarkan hasil penelitian suhu rata-rata POC adalah 24,5oC, pH rata-rata POC adalah 4,2, kandungan C-Organik POC cangkang telur adalah 0,00000194% sedangkan POC/MOL adalah 0,00000228%, kandungan N POC cangkang telur adalah 0,001200% sedangkan POC/MOL adalah 0,001600%.
