Authors:   Mahagarmitha, Mahagarmitha Rilia Rigina
Published: January 2023

The development of a city can be influenced by several things, including the geographical location and the condition of the natural resources of the region or area, one example is the city of Balikpapan whose development was initiated by the presence of petroleum natural resources, so that until now the city of Balikpapan is still known as "Oil City". Another advantage that makes the development of the city of Balikpapan is faster because it is supported by the geographical condition of the city of Balikpapan so that it becomes more strategic and is used as a stopover place both between cities and between provinces. As a stopover, the characteristics that can become the identity of a region are very important. To realize this, this research was carried out, using descriptive and qualitative methods in analysis and discussion. From the results of the analysis, it is known that it is necessary to maintain the physical form of an area, especially those that have historical values in the course of city development, one of which is by revitalizing and conserving areas in the city.

East Borneo has a lot of potential and natural resources that have not been fully developed, including in the tourism sector. Kutai Kartanegara Regency is experienced rapid progress in the tourism sector and continues to be developed until now. One of the popular tourist objects is Kumala Island as a cultural tourism object. However, within one year this tourist attraction experienced a decrease in the number of visitors because the management was considered less than optimal. Therefore, there is a need for a study of the level of visitor satisfaction at a tourist attraction to see what facilities must be improved in order to attract visitors again. This study uses a descriptive qualitative method with a Likert scale to see the level of satisfaction of visitors to Kumala Island tourism. From the research results, the Attractions and Accessibility aspects in Pulau Kumala have been satisfactory, but the amenities are still unsatisfactory so they must be addressed to attract visitors again.
Christian Martyrdom Never Expires: Some Theological and Ethical Aspects of Obedience usque ad sanguinem
Authors: Nowosad Sławomir
Published: January 2023

Both in the past and today an act of bearing witness to faith in God through martyrdom has been a unique sign and testimony of love for Christ who himself was obedient to the Father usque ad mortem. It is at the same time a clear judgment against those cultures, which acknowledge odium fidei. In his moral encyclical Veritatis Splendor John Paul II points to several arguments in order to emphasize that the way of martyrdom has lost none of its relevance and significance for Christians nowadays. The Pope’s claim is grounded on the fact that “faith possesses a moral content” and so it is false to separate faith (credenda) from moral life (agenda) of those who believe. Consequently, in particular circumstances Christians are called to be ready to lay their lives both for love of God and acceptance of his commandments. Through imitating their Lord usque ad sanguinem his disciples demonstrate and defend their human dignity received from the Creator, the holiness of God’s law as well as the holiness of the Church.

Znaczenie konia w życiu człowieka jest bezsprzeczne. Od zarania dziejów to wyjątkowe zwierzę pełni niezwykle ważną rolę w wielu obszarach działalności – np. transporcie, sztuce czy rolnictwie. Mimo wielu zmian kulturowych i znacznego rozwoju na poziomie technicznym i mechanicznym, koń wciąż jest niezbędnym elementem ludzkiego życia, choć współcześnie wykorzystuje się go inaczej niż kiedyś – częściej w celach turystycznych, rekreacyjnych, a także terapeutycznych. Przebywanie w towarzystwie konia, opieka nad nim i oczywiście jeździectwo, pozytywnie wpływają na emocje, pomagają w niwelowaniu zaburzeń w sferze fizycznej, psychicznej i społecznej. Jazda konna wpływa na odporność i hartuje nie tylko organizm, lecz i charakter człowieka.
Angular properties of refractive index sensor based on reflection interferometer
Authors: Terentyev V. S.  , Simonov V.A.
Published: January 2023

The angular properties of sensor, implemented in Kretschmann?s scheme, where the optimized for oblique incidence of light thin-film reflection interferometer acts as a sensing element, are described in the paper. Analytical equations, defining the sensor?s properties for S and P polarization states at working wavelength in vicinity of working angle of incidence, are provided, as well as approximate equations for main parameters of sensor: sensitivity, angular full width at half maximum, contrast and figure of merit. The possibility to vary the named parameters by choosing appropriate metal and dielectric layers of the structure is shown. For an example, the numerical calculations are made for one of special cases, optimized for S polarization state, as having larger figures of merit. The dependencies of angular properties on number of layers and base thickness are demonstrated. It is shown, that angular measurements with this method are theoretically capable of infinite figures of merit, and in practice they are only limited by losses in layered structure and beam divergency. The recommendations for experimental realization of method are given. Keywords: reflection interferometer, total internal reflection, refractive index sensor.
Implementation of Morse potential for approximation of vibrational terms of diatomic molecules
Authors: Denisov G. S.  , Tokhadze K. G.
Published: January 2023

We analysed the problem of approximation of the potential function of a diatomic molecule by a Morse model function with constant anharmonicity ν x using the Birge-Sponer extrapolation. The analysis of the approximations used in the derivation of the Morse equation shows that the solution of this problem is ambiguous. A scheme for optimizing the selection of initial parameters is proposed, which is illustrated by examples taken from the literature. The advantages of delineation of anharmonicity in the excitation of vibrational levels by deviations of the value ν x from the constant value according to Morse are demonstrated. An attempt is made to use the dimensionless anharmonicity parameter x* as a universal characteristic of the shape features of the electronic term of the molecule. Keywords: Morse potential, diatomic molecule, Birge-Sponer extrapolation, anharmonicity, electronic terms, vibrational structure.

In the paper, results of measurements of the optical response of chalcogenide glasses of the Ga5Ge20Sb10Se65 composition doped with rare-earth ions Tb3+ or Dy3+, in the wavelength range of 0.7 – 1.5 μm by the method of IR spectroscopy are presented. Parameters characterizing the fundamental absorption band edge of the glasses - optical bandgap energy, Urbach tail parameter and weak absorption tail parameter - have been evaluated. It has been found that doping in low concentrations (up to 0.3 mass%) does not influence the optical bandgap energy and optical properties of the glasses in the range of the Urbach tail, but in the range of the weak absorption tail, optical response of the glasses depends on the activator concentration. Crystallization of the glasses produced by the direct melting method also depends on the activator concentration. In the glasses doped with Dy3+, absorption bands of the ion are located in the range of the weak absorption tail of the glass that makes possible energy transfer between the ions and the gap states of the charge carriers.

Based on the semiclassical theory of the interaction of two-frequency laser radiation with a resonant atomic medium, an analytical expression is obtained that describes the form of resonances of electromagnetically induced transparency detected in a cell with a finite direction in the longitudinal laser beam direction with an anti-relaxation coating of walls, taking into account the motion of atoms and collisions with walls. The following types of reflection from walls are considered: diffuse, specular, and specular-incoherent. It is found that in a number of cases the diffuse type of reflection exhibits the properties of a mirror-incoherent one. It is also shown that the nondegeneracy of the excited state in a number of cases significantly changes the shape of the transparency resonance.

A generalization of the calculation of the formation of ghost images in the course of backward four-photon mixing to the real situation of non-planar spatially limited pumping, which has a Gaussian profile of the fundamental laser mode, is developed, taking into account the specifics of the formation of phantom images. Computer images have been obtained that make it possible to estimate the spatial resolution of the systems. A relatively simple equivalent scheme for describing the process is proposed, which shows that the effect of diffraction in nonlinear systems is similar to its role in ordinary linear optics with a limited aperture. A fiber-optic version of the formation of ghost images is proposed, suitable for the study of hard-to-reach cavities and organs of the human body, which allow the introduction of a thin fiber bundle there.

We review osmotic stress studies of G-protein-coupled receptor rhodopsin. Despite the established presence of small amounts of structural water in these receptors, the influence of bulk water on their function remains unknown. Investigations of osmotic stress effects on the GPCR archetype rhodopsin have provided unique data about the role of water in receptor activation. It was discovered that osmolytes shift the rhodopsin equilibrium after photoactivation, either to the active or inactive conformations depending on their molar mass. Experimentally at least 80 water molecules have been found to enter rhodopsin in the transition to the active state. We propose that this influx of water is a necessary condition for receptor activation. If the water movement is blocked, e.g., by large osmolytes or by dehydration, then the receptor does not undergo its functional transition. The results suggest a new model whereby rhodopsin becomes swollen and partially unfolded in the activation mechanism. Water thus acts as a powerful allosteric modulator of functioning for rhodopsin-like receptors.

In the frequency range from 16 to 50 THz, the transmission, reflection, and absorption spectra of arrays of heterogeneous Ni/Co, FeNi/Co, and Ni/Fe nanowires grown in track polymer membranes by the galvanic method have been studied. The absorption spectra showed that the fraction of the radiation power absorbed by the nanowires and its spectrum depend on the materials of the nanowires. The features of the spectra can be explained by the accumulation of nonequilibrium spin due to electron diffusion and its relaxation stimulated by external terahertz (THz) radiation, which can be used to create a THz radiation detector. In addition, negative absorption was found for FeNi/Co nanowires, which can be explained by the laser effect on spin-flip transitions, which can be used to create a THz radiation source operating at room temperature. Keywords: nanowires, THz radiation, THz spectroscopy, spin-flip transitions, metamaterial.

Published: January 2023

In this article we present the results of time-of-flight mass spectrometry of volatile products formed during the electrical breakdown of polyethylene terephthalate and polypropylene polymer films in high vacuum. During the breakdown of films, all the substance emitted from the breakdown channel is a gas of low-molecular products of destruction of macromolecules. The breakdown mass spectra do not contain lines of carbon molecules, the presence of which could indicate carbonation of the channel. To explain the formation of charge carriers, the ionization mechanism of destruction of macromolecules in an electric field is used without the involvement of impact ionization. The final stage of electrical breakdown (the flow of a high-density conduction current) occurs when the critical concentration of traps and electrons ~1024 m-3 is reached. Keywords: electrical breakdown, mass spectrometry, thermodestruction, ionization, macromolecule, trap.

Using direct laser lithography and wet etching of polished vicinal Si(111) wafers, a technology was developed and diffraction gratings 500 grooves/mm with a blaze angle of 4o were fabricated. The manufacturing process of a reflective Si-grating with the triangular profile (sawtooth) can be divided into four main steps: (1) obtaining a pattern of a protective mask for grooves etching; (2) anisotropic etching of grooves in KOH solution; (3) etching to smooth the grating profile and polish the surface of working facets; (4) coating to increase reflectivity. The samples obtained were characterized using scanning electron microscopy and atomic force microscopy methods to determine the shape of the groove profile and roughness: the shape turned out to be close to the ideal triangular, and the RMS roughness was less than 0.3 nm. Using PCGrateTM software and taking into account the measured real groove profile, the diffraction efficiency of gratings operating in classical and conical mounts in soft-X-ray and extreme ultraviolet radiation has been simulated. The obtained efficiency values are close to the record ones for the corresponding spectral range and the Au-coating of the grating. Keywords: diffraction grating, wet etching technology of Si, sawtooth groove profile, AFM, SEM, diffraction efficiency modelling.

Association Between Purchase of Over-the-Counter Medications and Ovarian Cancer Diagnosis in the Cancer Loyalty Card Study (CLOCS): Observational Case-Control Study
Authors: Brewer Hannah R , Hirst Yasemin , Chadeau-Hyam Marc , Johnson Eric , Sundar Sudha , Flanagan James M
Published: January 2023

Background

Over-the-counter (OTC) medications are frequently used to self-care for nonspecific ovarian cancer symptoms prior to diagnosis. Monitoring such purchases may provide an opportunity for earlier diagnosis.

Objective

The aim of the Cancer Loyalty Card Study (CLOCS) was to investigate purchases of OTC pain and indigestion medications prior to ovarian cancer diagnosis in women with and without ovarian cancer in the United Kingdom using loyalty card data.

Methods

An observational case-control study was performed comparing purchases of OTC pain and indigestion medications prior to diagnosis in women with (n=153) and without (n=120) ovarian cancer using loyalty card data from two UK-based high street retailers. Monthly purchases of pain and indigestion medications for cases and controls were compared using the Fisher exact test, conditional logistic regression, and receiver operating characteristic (ROC) curve analysis.

Results

Pain and indigestion medication purchases were increased among cases 8 months before diagnosis, with maximum discrimination between cases and controls 8 months before diagnosis (Fisher exact odds ratio [OR] 2.9, 95% CI 2.1-4.1). An increase in indigestion medication purchases was detected up to 9 months before diagnosis (adjusted conditional logistic regression OR 1.38, 95% CI 1.04-1.83). The ROC analysis for indigestion medication purchases showed a maximum area under the curve (AUC) at 13 months before diagnosis (AUC=0.65, 95% CI 0.57-0.73), which further improved when stratified to late-stage ovarian cancer (AUC=0.68, 95% CI 0.59-0.78).

Conclusions

There is a difference in purchases of pain and indigestion medications among women with and without ovarian cancer up to 8 months before diagnosis. Facilitating earlier presentation among those who self-care for symptoms using this novel data source could improve ovarian cancer patients’ options for treatment and improve survival.

Improving Transparency in the Residency Application Process: Survey Study (Preprint)
Authors: Ulin Lindsey , Bernstein Simone A , Nunes Julio C , Gu Alex , Hammoud Maya M , Gold Jessica A , Mirza Kamran M
Published: January 2023

BACKGROUND

Increasing numbers of residency applications create challenges for applicants and residency programs to assess if they are a good fit during the residency application and match process. Applicants face limited or conflicting information as they assess programs, leading to overapplying. A holistic review of residency applications is considered a gold standard for programs, but the current volumes and associated time constraints leave programs relying on numerical filters, which do not predict success in residency. Applicants could benefit from increased transparency in the residency application process.

OBJECTIVE

This study aims to determine the information applicants find most beneficial from residency programs when deciding where to apply, by type of medical school education background.

METHODS

Match 2023 applicants voluntarily completed an anonymous survey through the Twitter and Instagram social media platforms. We asked the respondents to select 3 top factors from a multiple-choice list of what information they would like from residency programs to help determine if the characteristics of their application align with program values. We examined differences in helpful factors selected by medical school backgrounds using ANOVA.

RESULTS

There were 4649 survey respondents. When responses were analyzed by United States-allopathic (US-MD), doctor of osteopathic medicine (DO), and international medical graduate (IMG) educational backgrounds, respondents chose different factors as most helpful: minimum United States Medical Licensing Examination (USMLE) or Comprehensive Osteopathic Medical Licensing Examination (COMLEX) Step 2 scores (565/3042, 18.57% US-MD; 485/3042, 15.9% DO; and 1992/3042, 65.48% IMG; P<.001), resident hometown region (281/1132, 24.82% US-MD; 189/1132, 16.7% DO; and 662/1132, 58.48% IMG; P=.02), resident medical school region (476/2179, 22% US-MD; 250/2179, 11.5% DO; and 1453/2179, 66.7% IMG; P=.002), and percent of residents or attendings underrepresented in medicine (417/1815, 22.98% US-MD; 158/1815, 8.71% DO; and 1240/1815, 68.32% IMG; P<.001).

CONCLUSIONS

When applying to residency programs, this study found that the factors that respondents consider most helpful from programs in deciding where to apply differ by educational background. Across all educational groups, respondents want transparency around standardized exam scores, geography, and the racial or ethnic backgrounds of residents and attendings.

Currently, obesity is considered as a risk factor for many comorbid conditions. Computed tomography (CT) is considered the «gold standard» for analyzing the composition of the human body, in particular adipose tissue, but this method carries radiation exposure. The most accessible alternative non-invasive method is bioimbisometry (BIM), but the accuracy of its indicators in clinical practice today is questioned. Target. To carry out a comparative analysis of the indicators of visceral and parietal fat obtained by methods of non-invasive and minimally invasive diagnostics to identify the most informative, safe, cost-effective screening markers. Materials and methods. After basic anthropometric studies and angiography (AH) of the arteries of the head and neck in patients with clinical manifestations of vascular disorders of varying severity, an analysis of the body composition (BSC) of those examined using the Tanita analyzer scales was carried out. Results. It was found that the body mass index (BMI) changed depending on the absence or presence of arterial stenosis on CT data. According to CT, depending on the degree of progression of stenosis by plaques, a positive correlation was found between the growth of epicardial adipose tissue (EFT) and perivascular adipose tissue (PAT); between BMI, obtained by anthropometry and RVT, obtained by CT; between the percentage of visceral fat obtained by the BIM method and EFT obtained by the CT method. The study obtained a negative correlation between the degree of hydration of the body and EFT. The BMI obtained by the anthropometry method and the BIM method when compared by the Mann-Whitney test did not differ statistically significantly, which indicates the possibility of express BMI assessment by the BIM method, taking into account the measurement error. Conclusions. The volume of EFT and RVT, measured on CT, can act as an independent marker in assessing the severity of atherosclerotic lesions. In the course of the study, it was proved that the CST indices obtained by the BIM method did not contradict the CT data, and increased depending on the progression of arterial stenosis.

Shu brocade is an important part of Chinese traditional culture, and it is also the first of the “Four Famous Brocades” in my country. Shu brocade has long been not only a handicraft, but also a symbol of cultural commodities, which has been integrated into literary works throughout the ages, into our daily consumption, and even into the 5,000-year-old Chinese traditional culture. Many handicrafts were eventually abandoned by history because of the complexity of inheritance techniques or because they could not keep up with the trend of the times. However, Shu brocade has been passed down from generation to generation for more than two thousand years, from ancient times to modern times. This is in line with the huge cultural characteristics and Commodity value is inseparable.

Autophagy is a crucial mechanism for the functioning and survival of pancreatic beta cells. Its dysregulation has been associated with obesity, insulin resistance, and glucose intolerance. Furthermore, decreased autophagy in insulin-secret ing beta cells has been reported to contribute to the devel opment of type 2 diabetes mellitus (T2DM), which constitutes about 95% of all diabetes cases and is a chronic metabolic disease that it currently affects millions of people around the world. In different models of rodents, whether diabetic or obese, it has been observed that treatment with autophagy enhancers lowers glucose levels, increases insulin sensitivity, and protects beta cells from apoptosis. As stated above, it has recently been proposed to carry out an early intervention in patients with T2DM, using drugs that promote autophagy, which could help preserve the mass of beta cells and prevent the progression of the disease. This review provides an over view of the importance of the physiological process of auto phagy and its imminent role in the development of T2DM.

Abstract: MRI plays a significant role in brain tumor analysis, diagnosis and treatment planning. It’s useful to doctor to determine the preceding steps of a brain tumor. Brain tumor detection and analysis by using MRI images is a challenging task because of the complex structure of the brain. Abnormal growth of tissues in the brain which affect proper brain functions is considered as a brain tumor. CT-scan is not always preferred method for detection. MRI images provide greater result than CTscan and X-rays. In this numerous pre-processing, post-processing, and methods like contrast enhancement, Filtering, Edge detection, and post-processing techniques like Threshold, Segmentation, Histogram, Morphological operation through image processing (IP) tool, and image segmentation techniques is available in MATLAB for detection of brain tumor images (MRIImages) are discussed

Abstract: Health data is usually in a scattered manner as they are usually gathered by various entities. The data’s scatteredness develops a burden in designing adequate health bills which ensure the well-being of the patients. Moreover, the concerns in achieving synchronization and instantaneous access to such data worsens the problem all the more. So, designing a system that can ensure the integrity, security, preciseness, and accessibility of the patient’s medical data is of paramount importance. Health systems based on blockchain can guarantee the above features and protect data from being tampered or from any kind of attacks. Blockchain also helps in management of data and its flawless integration. It makes most of its smart contracts feature to execute the several requests and queries related to the patients (medicine, appointments, medical procedures, lab tests or previous medical information). All the stakeholders in the system should be able to obtain the medical data preserved in a database not having to compromise on its credibility. In this survey, we examine the previous research work various authors have carried out on implementing blockchain in several aspects of healthcare.
Study on Comparision of Life Cycle Cost Between White Topping and Btiuminuos Overlays
Authors: SM Rashmi
Published: January 2023

Abstract: The focus of the present study is on construction of long-lasting and better performing pavements. Usually, with respect to the rehabilitation of the pavement, the construction agencies go with the bituminous overlays as their first priority without considering the condition of the existing pavement structure. But the advantages of cement concrete (CC) pavements that have proved to perform better and are considered to be long-lasting must be explored. The use of Thin White Topping (TWT), and Ultra-Thin White Topping (UTWT) pavements is currently gaining popularity in the area of pavement construction.. And hence it is the era where the Thin and Ultra-Thin White Topping methods are gaining their popularity. The present study provides details on the approaches adopted in measuring the performance of TWT and UTWT pavement surfaces built of plain cement concrete, cement in cement concrete replaced by 50% ground granulated blast furnace slag, cement in cement concrete replaced by an admixture called Conplast NC, and 50% of cement in cement concrete replaced by GGBS and Conplast NC. The study also includes comparison of strength of composite beams of various thicknesses when subjected to repeated wheel loads under Modified Immersion Wheel Tracking Equipment when supported by a 50mm thick bituminous layer below. The performance results on the tests on the specimens of 150mm thick admixture-added CC beam and the 100mm thick GGBS-cumAdmixture-added CC beam were almost the same. This indicated that the thickness of cement concrete slabs could be reduced by 50mm by replacing 50% of cement in cement concrete with GGBS-cum Admixture-added CC beam. Based on the study on cement concrete, and composite beams, and the study of life cycle costs, it was observed that a road surface with cement concrete overlay would be more appropriate when compared to a bituminous concrete (BC) overlay. Together, these findings suggest that the concrete overlay acts as the most economic method.

Abstract: Based on the site conditions and lateral earth pressure of soil plays important role in the selection of sheet pile wall. In the present day different types of sheet pile wall present in the market like as steel sheet pile wall , concrete sheet pile wall and timber etc. Concrete sheet pile walls are common in use. Modification in the properties of the concrete sheet piles is easier making it more economical as the utility of the section can be considerably increased according to projects requirement. Sheet pile wall deformation is dependent on the materials properties. Consequently, it is essential to research how different material types and properties affect the deformation and stress distribution of cantilever concrete sheet pile walls. A parametric analysis was carried out numerically using a case study that makes use of a base model to determine how long a sheet pile wall should be at the bottom of an embankment with various material types for ditch with a depth of 3m, 5m and 7m.to safeguard and improve the stability of the embankment , a sheet pile wall was temporarily constructed near the toe of the embankment. Analysing simulation data was completed with the aid of GE05FINE. The analysis findings revealed that when subjected to the same loading situation, bending moment and shear force varies with the material properties. Therefore, it is wise to carefully select the sheet pile wall materials in accordance with the projects requirements.

Published: January 2023

Abstract: Geopolymer concrete has had an extra edge over normal concrete for the past 2-3 decades. According to research, geopolymer concrete offers improved strength, modulus of elasticity, and durability. In this work, Ordinary Portland cement is fully replaced by a mixture of Sugar Cane Bagasse Ash(SCBA) and Ground Granulated Blast Furnace Slag(GGBS), with alkaline liquids added for reactivity. Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3) are used for the polymerization to achieve good workability in the geopolymer concrete. The combined quantities of geopolymer concrete were optimized using the Taguchi method to meet the specified strength parameters for the concrete grade of M30 with nine mixes. Binder content, which included three proportions of SCBA and GGBS, NaOH/Na2SiO3 ratios (1:2, 1:2.5, and 1:3), molarity(4M,8M,12M), and alkaline activator to binder content ratio(AAC/BC) of 0.4,0.5,0.6 were among the various parameters of study. Compressive strength and split-tensile strength was investigated using these components and variables during the work.
