Published: March 2023

The effect of the resonant tunneling of signals through an overcritical plasma layer in the presence of an external static magnetic field is considered. The aim of the study is to demonstrate the effectiveness of the combined usage of two methods for overcoming radio blackout for aircrafts moving in dense layers of the atmosphere at supersonic velocities: the method of resonant tunneling of the signal in the presence of a dielectric layer and the magnetic windows method. The features of dielectric resonator filling with an electromagnetic wave field are studied for various parameters. The values of the magnetic field induction providing the best signal propagation results through the plasma layer are estimated
Усиление угловой дисперсии лазерных гармоник высокого порядка при взаимодействии с плотными плазменными кластерами

Published: March 2023

Diffraction gratings and photonic crystals are widely used to control light. However, their capabilities are less effective in the case of extreme ultraviolet (XUV) radiation due to the high absorption of the optical material in this frequency range. In this work, we study the possibility of enhancing the angular dispersion of XUV radiation due to scattering by plasma clusters whose dimensions are smaller than the incident radiation wavelength. An analytical model was developed using the plasma Drude dielectric function and the Mie scattering theory in the quasi-static approximation. The resonant parameters of the target for the tenth harmonic of the Ti : Sa-laser are determined, and a significant enhancement of the scattered field in this case compared to the laser one is shown. Under resonance conditions for one cluster, the diffraction of radiation by an array of such clusters is simulated using the CELES code. The results obtained show a significant enhancement of the scattered field in the resonance case for large angles corresponding to the theory of Bragg-Wulf diffraction, which makes it possible to control high harmonics of laser radiation in the XUV range using ionized cluster gas.

Designing of the ultrafast terahertz photonics devices requires materials with the biggest nonlinear refractive index coefficient n2 and the lowest settling time of the nonlinear response τ in the terahertz spectral range. In the present study, we show that the ratio n2/τ for media with the vibrational nonlinearity in the terahertz range is determined by the square of the medium thermal expansion coefficient and the fifth power of its dominative stretching vibrational mode frequency. These findings are based on the theory of the media vibrational nature nonlinear polarization response to incident THz radiation. We provide estimated values of the n2/τ ratio for a group of liquids and crystal materials. According to our evaluations, n2/τ value for alpha-pinene in the terahertz spectral range is about 10^6 cm^2/J and is almost the biggest one compared to materials with different nonlinearity types in various spectral ranges.

Authors:   Associate Professor, Department of Physics, Feroze Gandhi College, Raebareli (India), JAISWAL SHIKHA
Published: March 2023

The optical signal processing is the future of communication network. High speed all-optical packet routing is one of the essential applications of all-optical networks which is only possible with the development of all-optical logic technology. The development of optical logic elements and circuits are the steps in the growth of this technology and higher speed up to Tbit/sec can be achieved. The optical carrier frequency range 1013 to 1016 Hz provides enormous potential bandwidth with superior information carrying capacity over a long transmission distance. The need of higher capacity is continuing to encourage research in wavelength division multiplexing (WDM) and optical time division multiplexing (OTDM) based transmission systems, which need optical demultiplexing and wavelength conversion technology. Therefore, for high-speed optical networks, it is required to develop the all-optical gates to avoid power consumption in opto-electronics conversion. All optical logic gates perform computing operations, storage and transmission of data using light also known as optical computing. Optical technology promises massive upgrades in the efficiency and speed of computers, aswell as significant shrinkage in their size and cost. The non-linear optical device to be used i.e. Semiconductor Optical Amplifier (SOA) has proved to be the promising for all optical functions like wavelength conversion, logic functions, signal representation in all optical domain. Its compact size, high gain, fast response, strong refractive index variation, easy to manufacture and integration, and power efficiency makes it most optimum device for optical signal processing. In this paper, the application of SOA in optical processing is thoroughly reviewed and orient towards the latest application in neural networks.

Authors: Fareed Yalda Karam , Abdalla Goreal Amer
Published: March 2023

Objective: This study aimed at determining the prevalence of CMV infection among pregnant women at the end of pregnancy and CMV transmission to their newborns.

Methods: This is cross sectional study, 213 pregnant women at delivery and their newborn babies from the Obstetrics and Gynecology Hospital in Duhok /Iraq were enrolled. A questionnaire was prepared to be answered by participants, including age, place of residence, educational level, and obstetric history as number of births, any bad obstetric history such as abortion, still birth, intrauterine growth retardation, congenital anomalies after birth.3-5 ml of blood was drawn from each woman and examined by ELISA kit to check for the presence of Anti CMV IgM, IgG, then IgG avidity test for those with positive (IgG and IgM). Samples of cord blood were collected from newborns after birth and checked for the presence of CMV IgM by ELISA and CMV –DNA by conventional PCR using specific primers to diagnose congenital infection and determine the rate of viral transmission from infected women.

Results: Serological examinations showed that 212 (99.5%) participants were CMV-IgG positive, 15 (7%) were positive for anti-CMV IgM and IgG antibodies, IgG avidity test for 15 women were of high avidity (>89%) which indicated non primary infections. Cord blood of newborns of those 15 women with positive IgG and IgM tested negative for Anti CMV IgM by ELISA and no CMV-DNA was detected by PCR, which revealed no transmission from those pregnant to their newborns.

Conclusion: This study demonstrated high prevalence of CMV among examined pregnant women in Duhok city which makes them prone to non-primary infection. IgG avidity test is of high efficacy to interpret the detection of IgG and IgM together in pregnant women. Cord blood examination for the existence of CMV-IgM and CMV-DNA after delivery could exclude congenital infection.

Objective: The aim of the presented word was to assess the diagnostic accuracy of serum Nesfatin-1 in type 2 diabetes mellitus and its relationship with C-peptide level in obese and non-obese type-2 diabetic women of Iraqi population.

Methods:  A case-control study was performed on 50 type 2 diabetic patients admitted in Al-Hussein Teaching Hospital and Al-Hassan center of diabetes and endocrinology unit / Kerbala health directorate – Iraq and another 50 control individuals, during the period from April, 2022 – Jan. 2023). The T2DM groups were divided into two groups 25 obese and 25 non-obese; also the control group was divided into 25 obese and 25 non-obese as apparently healthy groups. The ELISA Kit was used to measure serum Nesfatin-1 and C-peptide, and random serum glucose was measured by enzymatic colorimetric method, and lipid profile test were measured through spectrophotometric technique, instead of HbA1c% was determined using HPLC method.

Results: The results observed indicated that Nesfatin-1 levels shown a non-significant decrease in all of type 2 diabetic groups as compared with apparently healthy control group, while the C-peptide were significantly decreased in type 2 diabetic patients when compared with apparently control group. In addition, the random blood glucose and HbA1c% were shown significant elevation in type 2 diabetic patients as compared with apparently healthy control groups. The observed data indicated that Nesfatin-1 and C-peptide levels when comparing between type 2 diabetic patients and control in obese groups shown a risk factors depending upon the odd ratio observed (OR = 1.064 (1.011-1.119), 1.0200 (0.992-1.08)) respectively, but only Nesfatin-1 was shown to be significant. In BMI the levels of Nesfatin-1 and C-peptide, as shown the Nesfatin-1 was significant in obese groups, while the C-peptide as shown significant in normal weight groups. The optimal diagnostic points for Nesfatin-1 were (sensitivity = 98%, specificity = 90%) at a level (Cut-off points) = 39.13, while C-Peptide levels: (sensitivity = 98%, specificity = 94%) at a level (Cut-off points) = 15.99.  Both markers have p-values of the AUC were <0.001 and statistically significant.

Conclusion: Accordingly, it was concluded that a significant relationship between circulating Nesfatin-1 levels and type 2 diabetes. Nesfatin-1 appears to be able to contribute to the treatment of obesity and diabetes because of its anorexigenic and antihyperglycemic effects. In addition, C-peptide is a known biomarker of insulin resistance and beta-cell function. High specificity and sensitivity analyzed results were obtained by ROC analysis for both markers in T2DM.

Authors: Less Jacob , Nguyen Cathina , Teng Valerie , Lin Steven
Published: March 2023

Background and Objectives: Sparse research exists on evaluating the effects of medical scribing programs on the educational trajectory of prehealth students. This study assesses the impact of the Stanford Medical Scribe Fellowship (COMET) on its prehealth participants’ educational goals, preparation for graduate training, and acceptance into health professional schools.
Methods: We distributed a 31-question survey with both closed- and open-ended questions to 96 alumni. The survey collected participant demographics, self-reported underrepresented in medicine (URM) status, pre-COMET clinical experiences and educational goals, application to and acceptance at health professional schools, and perceived impact of COMET on their educational trajectory. SPSS was used to complete the analyses.
Results: The survey had a 97% (93/96) completion rate. Among all respondents, 69% (64/93) applied to a health professional school and 70% (45/64) were accepted. Among URM respondents, 68% (23/34) applied to a health professional school and 70% (16/23) were accepted. Overall acceptance rates for MD/DO and PA/NP programs were 51% (24/47) and 61% (11/18), respectively. URM acceptance rates for MD/DO and PA/NP programs were 43% (3/7) and 58% (7/12), respectively. For current or recently graduated health professional school respondents, 97% (37/38) “strongly agreed” or “agreed” that COMET helped them succeed in their training.
Conclusions: COMET is associated with a positive impact on the educational trajectory of its prehealth participants and a higher acceptance rate into health professional schools than the national rates for both overall and URM applicants. Scribing programs may serve as pipeline development and help increase the diversity of the future health care workforce.

Authors: Traxler Matthew , Borick Jamie , Ofei-Dodoo Samuel , Curry Amy , Love Sarah , Nash Cynthia
Published: March 2023

Background and Objective: Although the opioid epidemic continues to affect millions of Americans, many family physicians feel underprepared to perform chronic pain management (CPM) and treat opioid use disorder (OUD). To address this gap, we created organizational policy changes and implemented a didactic curriculum to help improve patient care, including medication-assisted treatment (MAT) into our residency. We investigated whether the educational program improved the comfort and ability of family physicians to prescribe opioids and utilize MAT.
Method: Clinic policies and protocols were updated to align with the 2016 Centers for Disease Control and Prevention Guidelines for Prescribing Opioids. A didactic curriculum was created to improve resident and faculty comfort with CPM and introduce MAT. An online survey was completed pre- and postintervention between December 2019 and February 2020, utilizing paired sample t test and percentage effective (z test) to assess for change in provider comfort with opioid prescribing. Assessments were made using clinical metrics to monitor compliance with the new policy.
Results: Following the interventions, providers reported improved comfort with CPM (P=.001) and perception of MAT (P<.0001). Within the clinical setting there was significant improvement in the number of CPM patients who had a pain management agreement on file (P<.001) and completed a urine drug screen within the past year (P<.001).
Conclusion: Provider comfort with CPM and OUD increased over the course of the intervention. We were also able to introduce MAT, adding a tool to the toolbox to help our residents and graduates treat OUD.
Laser ablation mass spectrometry blast through detection in R
Authors: Searle-Barnes Alex , Milton Andy , Standish Christopher , Foster Gavin , Ezard Thomas
Published: March 2023

Rational: Organisms that grow a hard carbonate shell or skeleton, such
as foraminifera, corals or molluscs, incorporate trace elements into
their shell during growth that absorbs the environmental change and
biological activity they experienced. These geochemical signals locked
within the carbonate are archives used in proxy reconstructions to study
past environments and climates, to decipher taxonomy of cryptic species
and to resolve evolutionary responses to climatic changes. Methods: Here
we use a laser ablation inductively coupled plasma mass spectrometry
(LA-ICP-MS) as a time resolved acquisition to quantify the elemental
composition of carbonate shells. We present the LABLASTER (Laser
Ablation BLASt Through Endpoint in R) package, which imports a single
time resolved LA-ICP-MS analysis, then detects when the laser has
ablated through the carbonate as a function of change in signal over
time, and outputs key summary statistics. We provide two worked examples
within the package: a planktic foraminifera and a tropical coral.
Results: We present the first R package that improves signal: noise
ratios in data reduction workflows by automating the detection of when
the laser has ablated through a sample using a smoothed time-series and
subsequent removal of off-target data points. The functions are flexible
and adjust dynamically to enhance the signal: noise ratio of the desired
geochemical target. Visualisation tools for manual validation are also
included. Conclusions: LABLASTER increases transparency and
repeatability by algorithmically identifying when the laser has either
ablated fully through a sample or across a mineral boundary and is thus
no longer documenting a geochemical signal associated with the desired
sample. LABLASTER’s focus on better data targeting means more accurate
extraction of biological and geochemical signals.

Published: March 2023

The numerical solution of the Darcy-Forchheimer flow of a Williamson
nanofluid across a spinning disc is discussed in this paper. This issue
took into account the existence of mobile microorganisms and the
consequences of radiation exposure. Parameters were used to build the
fundamental governing equations, and then these partial differential
equations were transformed into ordinary differential equations using
the appropriate similarity transformations. The BVP4C is then used to
perform a numerical solution of these equations. Several factors’
impacts on tangential and radial velocities, temperatures,
concentrations, and motile microorganisms were explored, along with
their corresponding visual representations. The physical implications of
the findings are also elaborated on in great detail.
Construction of Long-term Seismic Catalog with Deep Learning and Characterization of Preseismic Fault Behavior in the Ridgecrest-Coso Region (2008-2019)
Authors: Zhou Yijian , Ghosh Abhijit , Fang Lihua , Yue Han , Zhou Shiyong
Published: March 2023

Long-term seismicity is an effective tool to infer fault properties at
depth, but the catalog construction is challenging because of the large
data volume. We propose a new deep learning-based workflow that follows
a “Train-Detect-Pick” procedure, which solves the generalization
problem in AI pickers. We apply the new workflow on the preseismic phase
(2008-2019) of Ridgecrest-Coso region. Results show that the new
workflow realizes efficient and stable detection, and well substitutes
matched filter. Our new catalog helps characterize the preseismic fault
behavior: (1) the Ridgecrest area has a distributed deformation, and the
2019-ruptured segment has a persistent asperity; (2) the central Garlock
fault is unfavorable for rupture propagation, because of its
discontinuous geometry and low coupling ratio; (3) the Coso geothermal
field generates intense and shallow seismicity, which has a high b-value
that does not correlate with seismicity rate and industrial production,
thus suggest a low stress level.
Understanding Contributions of Paleo-Informed Natural Variability and Climate Changes on Hydroclimate Extremes in the Central Valley Region of California
Authors: Gupta Rohini S , Steinschneider Scott , Reed Patrick M.
Published: March 2023

To aid California’s water sector to better manage future climate
extremes, we present a method for creating a regional ensemble of
plausible daily future climate and streamflow scenarios that represent
natural climate variability captured in a network of tree-ring
chronologies, and then embed anthropogenic climate change trends within
those scenarios. We use 600 years of paleo-reconstructed weather regimes
to force a stochastic weather generator, which we develop for five
subbasins in the San Joaquin River in the Central Valley region of
California. To assess the compound effects of climate change, we create
temperature series that reflect scenarios of warming and precipitation
series that are scaled to reflect thermodynamically driven shifts in the
daily precipitation distribution. We then use these weather scenarios to
force hydrologic models for each of the San Joaquin subbasins. The
paleo-forced streamflow scenarios highlight periods in the region’s past
that produce flood and drought extremes that surpass those in the modern
record and exhibit large non-stationarity through the reconstruction.
Variance decomposition is employed to characterize the contribution of
natural variability and climate change to variability in
decision-relevant metrics related to floods and drought. Our results
show that a large portion of variability in individual subbasin and
spatially compounding extreme events can be attributed to natural
variability, but that anthropogenic climate changes become more
influential at longer planning horizons. The joint importance of climate
change and natural variability in shaping extreme floods and droughts is
critical to resilient water systems planning and management in the
Central Valley region.

Novel theorems for metallic structures on the frame bundle of the second order
Authors: Khan Mohammad Nazrul Islam
Published: March 2023

It is well known that ?an almost complex structure? J that is J2 = ?I on the
manifold M is called ?an almost Hermitian manifold? (M, J,G) if G(JX, JY) =
G(X,Y) and proved that (F2M, JD,GD) is ?an almost Hermitian manifold? on the
frame bundle of the second order F2M. The term ?an almost complex structure?
refers to the general quadratic structure J2 = pJ + qI, where p = 0, q = ?1.
However, this paper aims to study the general quadratic equation J2 = pJ +
qI, where p, q are positive integers, it is named as a metallic structure.
The diagonal lift of the metallic structure J on the frame bundle of the
second order F2Mis studied and shows that it is also a metallic structure.
The proposed theorem proves that the diagonal lift GD of a Riemannian metric
G is a metallic Riemannian metric on F2M. Also, a new tensor field ?J of
type (1,1) is defined on F2M and proves that it is a metallic structure. The
2-form and its derivative dF of a tensor field ?J are determined.
Furthermore, the Nijenhuis tensor N?J of a metallic structure ?J and the
Nijenhuis tensor NJD of a tensor field JD of type (1,1) on the frame bundle
of the second order F2M are calculated.

Authors: Choi Eun-Hack Andrew , Lee Kee-Joon , Choi Sung-Hwan , Jung Hwi-Dong , Ahn Hyung-Joon , Deguchi Toru , Cha Jung-Yul
Published: March 2023

Objectives

To compare skeletal and dentoalveolar changes of miniscrew-assisted rapid palatal expansion (MARPE) according to the length of the miniscrews.

Materials and Methods

This two-arm parallel-randomized controlled trial included 32 adult patients aged 19–35 years who received orthodontic treatment with MARPE. Patients were allocated to two groups, group long (L) and short (S), through block randomization according to the length of the miniscrews installed in MARPE. Cone-beam computed tomography was performed before expansion and after removal of the MARPE; superimposition of the images was conducted. The primary outcome included the amount of bone expansion and the change in the inclination of the anchorage teeth. The secondary outcome included the success rate of midpalatal suture opening and stability of the miniscrews. Blinding was performed during outcome assessment.

Results

The final sample comprised 31 patients. There was no significant difference in patient characteristics between group L (n = 16) and group S (n = 15). The change in the width of the processus zygomaticus (P = .010) and ectocanine (P = .001) was significantly higher in group L. A significantly higher success rate of the posterior miniscrews was seen in group L (P = .024). There was no statistically significant difference in the success rate of suture separation or change in tooth inclination. Notable complications were not reported.

Conclusions

MARPE with longer miniscrews can increase the amount of expansion of the maxillary basal bone and canine alveolar bone. Although it also aided in miniscrew stability, it did not guarantee successful midpalatal suture separation.

This study investigates the impact of the β2-receptor gene (ADRB2) polymorphism Gly16Arg on the metabolic response to epinephrine before and after repetitive hypoglycemia. Twenty-five healthy men selected according to ADRB2 genotype being homozygous for either Gly16 (GG) (n = 12) or Arg16 (AA) (n = 13) participated in 4 trial days (D1–4): D1pre and D4post with epinephrine 0.06 μg kg−1 ⋅ min−1 infusion and D2hypo1–2 and D3hypo3 with three periods of hypoglycemia by an insulin-glucose clamp. At D1pre, the insulin (mean ± SEM of area under the curve 44 ± 8 vs. 93 ± 13 pmol ⋅ L−1 h; P = 0.0051), glycerol (79 ± 12 vs. 115 ± 14 μmol ⋅ L−1 h; P = 0.041), and free fatty acid (724 ± 96 vs. 1,113 ± 140 μmol ⋅ L−1 h; P = 0.033) responses to epinephrine were decreased in AA participants compared with GG participants but without a difference in glucose response. There were no differences in response to epinephrine between genotype groups after repetitive hypoglycemia at D4post. The metabolic substrate response to epinephrine was decreased in AA participants compared with GG participants but without a difference between genotype groups after repetitive hypoglycemia.

Article Highlights

This study investigates the impact of the β2-receptor gene (ADRB2) polymorphism Gly16Arg on the metabolic response to epinephrine before and after repetitive hypoglycemia. Healthy men homozygous for either Gly16 (n = 12) or Arg16 (n = 13) participated in the study. Healthy people with the Gly16 genotype have increased metabolic response to epinephrine compared with the Arg16 genotype but without a difference between genotypes after repetitive hypoglycemia.

The reflection of the laser energy by the powder makes the laser energy no longer exhibit a Gaussian distribution. The purpose of this paper is to investigate the effect of the heat source model on the behavior of the molten pool in laser cladding. First, the Gaussian heat source is modified according to the law of laser energy reflection by powder, and a laser heat source model considering powder reflection is established. Then, the AM900 superalloy laser cladding model was established by using the fluid dynamics method with the modified Gaussian heat source and ordinary Gaussian heat source, respectively. The influence of the heat source model on the behavior of the laser cladding pool was studied. The thermal cycle curve was collected and the cladding layer morphology was obtained in the actual cladding process to verify the model. It is found that the impact of the droplet has the greatest impact on the flow pattern of the molten pool. The modified Gaussian heat source can reduce the peak temperature in the center of the molten pool (about 130 K), which can reflect the actual laser beam during cladding. The flow velocity of the molten metal simulated with the modified Gaussian heat source is slower than that of the ordinary Gaussian heat source, resulting in smaller melt pool width and penetration depth (reduced to 0.27 and 0.12, respectively). The improved heat source model is more in line with the actual cladding process.

La literatura en educación matemática muestra que la habilidad para resolver problemas de esa área está estrechamente relacionada con la comprensión del texto y los conocimientos previos del estudiante. Además, se ha identificado que aunque un estudiante pueda parecer experimentado en la lectura de textos variados, esto no garantiza su comprensión. Por eso, el objetivo de esta investigación fue analizar los procesos de comprensión textual en problemas matemáticos que involucran texto en un estudiante de 15 años durante un curso de álgebra de bachillerato. Para entender estos procesos se utilizaron elementos teóricos que permitieron identificar sus componentes, en particular las operaciones de segmentación y recontextualización en los procesos inductivo, deductivo y evolutivo subyacentes al fenómeno estudiado.

La metodología utilizada fue cualitativa y se empleó el método de estudio de caso. El estudiante seleccionado presentó compromiso y disponibilidad para explorar actividades que involucraron la comprensión de textos. Los instrumentos utilizados para la recolección de datos incluyeron hojas de trabajo, reportes escritos y una entrevista semiestructurada.

A partir del análisis de lo recabado se identificó que el trabajo del estudiante se caracterizó en un inicio por la exploración del contenido redaccional basado en el proceso inductivo de comprensión, del cual emergieron las unidades de texto implícitas y explícitas identificadas. En el proceso deductivo, se observó que el estudiante trabajó en relación con el significado de las fracciones como parte-todo y como índice comparativo entre dos cantidades o conjuntos de unidades. Asimismo, se destacó la importancia de entender que las fracciones son razones que permiten evidenciar la comparación.

The use of figurative language with the aim of strengthening the message conveyed, which is embedded in social communication between people in one community in the context of daily communication, is a unique thing to explore. By using a qualitative approach, this study aims to find out the use of figurative language and the figurative meaning used. The data in this study was in the form of words, utterances or spoken sentences that contain figures of speech in everyday communication. The method used in data collection was the method of observing and recording techniques. The data obtained was then analyzed by selecting, sorting, classifying data, reading, studying and removing unnecessary data. The results of the study show that in social communication, the Saluan people in Batu Itam Village use a lot of figures of speech in the form of simile, namely comparing one object to another. Other objects that are used as comparisons are substitute objects that represent actual objects or allude to other objects but are not pronounced. The Saluan people also use visible objects to become figurative components. Keywords: figurative language, social communication, simile

Background: The presence of anti-Saccharomyces cerevisiae antibodies (ASCA) has been reported in the serum of patients with several immune-inflammatory diseases.
Objective: To evaluate the presence of ASCA in patients with non-IgE-mediated hypersensitivity.
Methods: A group of 222 patients with non-IgE-mediated hypersensitivity was divided into three groups according to dermatologic, gastrointestinal, and respiratory symptoms. Group D was composed of 163 patients with dermatologic symptoms diagnosed as intrinsic atopic dermatitis and/or non-IgE-mediated urticaria. Group G was composed of 23 patients diagnosed with non-IgE-mediated gastrointestinal food allergies. Group R was composed of 36 patients with respiratory symptoms diagnosed as non-IgE-mediated rhinitis and/or non-IgE-mediated asthma.
Results: The Wilcoxon-Mann-Whitney U test comparing the precipitin’s titers of group G and group D showed a non-significant p-value of 0.83366. The Wilcoxon-Mann-Whitney U test comparing the precipitin’s titers of group R and group G showed a significant p-value of 0.00034. The Wilcoxon-Mann-Whitney U test comparing the precipitin’s titers of group R and group D showed a significant p-value < 0.0001.
Conclusion: The patients with respiratory symptoms diagnosed as non-IgE-mediated rhinitis and/or asthma presented significantly less humoral immunoreactivity against S. cerevisiae than patients with non-IgE-mediated food allergy and patients with intrinsic atopic dermatitis and/or non-IgE-mediated urticaria. The elevation of ASCA titers may be an unspecific marker of intestinal hyperpermeability, and possibly may participate in Gell and Coomb’s types II and/or type III hypersensitivity reactions responsible for the patient’s dermatologic and gastrointestinal symptoms.

Published: March 2023

Bandung is West Java's largest metropolitan city and Indonesia's third largest. The city of Bandung is very strategic in various aspects, such as accessibility, communication, public facilities, and the economy. The Increased population in Bandung indicates more complex ongoing human activities, which can then affect changes in land use. The land covers in urban areas tends to change more drastically over a short period e than in rural areas because of rapid urbanization. Therefore, urban phenomenon changes are ideally monitored and detected from satellite images with a multitemporal resolution. Vegetation greenness and built-up areas can identify through multitemporal remote sensing imagery. Changes in vegetation and built-up area can monitor using remote sensing with multitemporal imagery. The analysis of changes in vegetation and built-up area studied in Bandung City represents an area with rapid population growth. This study aims to: 1) Identify changes in vegetation greenness in Bandung City between 2014 and 2021, 2) Identify built-up area changes in Bandung City between 2014 and 2021, 3) Analyze the relevance between vegetation greenness and the built-up area in Bandung Cityâ€”the correlation between NDBI and NDVI through selected samples is representative of all data in Landsat 8 imagery. The proportion between the values of NDBI and NDVI samples is 0.9034. So, it is concluded that the two variables are positively correlated. Therefore, the studyâ€™s results recommend preserving vegetated land cover to conserve natural resources and prevent increased land surface temperature.Keywords: Remote Sensing Imagery, Built-Up Area, Vegetation Greenness, Bandung City
L’ATTACCAMENTO SPIRITUALE AL SANTO PADRE NELLA CHIESA GRECO-CATTOLICA DI ROMANIA
Authors: RUS Anton
Published: March 2023

Spiritual Attachment to the Holy Father Pope in Greek-Catholic Church in Romania. The present study captures the attitude of Romanian Greek Catholic believers towards the person of the Pope. This attitude is reflected in the relations that have existed over time between the Roman Pontiffs and the Greek Catholic Church on the territory of present-day Romania. On the one hand, there are various pontifical actions in favor of the Romanians united with the Church of Rome, and on the other hand, the Greek Catholic Romanians will be able to give their lives for the biblical truth of the Petrine primate.
REZUMAT: Atașamentul spiritual față de Sfântul Părinte Papa în Biserica Greco-Catolică din România. Studiul de față surprinde atitudinea credincioșilor greco-catolici români față de persoana Papei. Atitudinea respectivă se reflectă în relațiile care au existat de-a lungul istoriei între Pontifii Romani și Biserica Greco-Catolică de pe teritoriul actualii Românii. Pe de o parte, există diferite intervenții pontificale în favoarea românilor uniți cu Biserica Romei, iar pe de altă parte regăsim atitudini care determină în greco-catolicii români mărturii puternice care ating chiar nivelul sacrificiului suprem pentru adevărul biblic al primatului petrin.
