Published: May 2023

The characteristic temperatures for individual glass samples of quasi-ternary systems Ag2S–GeS2–As(Sb)2S3 were determined by differential thermal analysis method. Obtained data show that the glass transition temperature of the alloys is in the range typical of chalcogenide glasses. It was established that the glass transition temperature increases with the modifier content in the range of 402-421 K and 373-438 K for the Ag2S–GeS2–As(Sb)2S3 systems, respectively. For the constant Ag2S concentration, the value of the glass transition and crystallization temperatures increases with the content of germanium (IV) sulfide. The reduced glass transition temperature Tgr was calculated from obtained results which lies in the range of 0.62-0.73 and 0.59-0.70 for the glasses of the Ag2S–GeS2–As(Sb)2S3 systems, respectively, which indicates the high capacity of the samples to glass formation. Optical absorption spectra were measured at 297 K. The band gap energy Eg of the glasses of the Ag2S–GeS2–As(Sb)2S3 systems was estimated from the data on the spectral distribution of the absorption coefficient in the region of the absorption edge. It was determined that the absorption edge shifts to longer wavelengths with the increase of the GeS2 content in glasses, while the energy position of the absorption edge increases. Ade crease in the band gap energy is observed for all glass samples when a modifier is introduced into the glass-forming matrix. The characteristic energy of the degree of tailing of the absorption edge is in the range from 0.066 to 0.079 eV for all studied glass samples.

Cationic ion-conductors have found wide practical application as electric batteries. Among them the lithium-ion batteries are the most common commercially used. However, research is being actively carried out to improve the safety of these batteries. Among the possible compounds, silver-containing phases are attractive, since silver-ions, along with high values of ionic conductivity in solid-state, haven’t high chemical activity like the same alkali metal-ions. Realization of the crystal structure necessary for effective ion transport is observed in compounds of the argyrodite structure - a group of ternary chalcogenides and quaternary chalcohalogenides of multi-charged cations (Ge4+, Si4+, P5+). In this work, a study of heterovalent cationic P5+→Ge4+ substitution in the Ag8GeS6 enriched region was carried out. Single crystals of Ag8-x(Ge1-xPx)S6 (x = 0.25; 0.5) solid solutions were grown by the method of directional crystallization using a solution-melt technique. The grown single crystals are characterized by the absence of macrodefects, a dark gray color with a metallic luster, and dimensions of l = ~3 cm and d = 1.2 cm. Using the Rietveld refinement method, the crystal structure was established and the lattice parameters of Ag8-x(Ge1-xPx)S6 (x = 0.25; 0.5) solid solutions were determined. Established, that single crystals of Ag8-x(Ge1-xPx)S6 (x = 0.25; 0.5) solid solutions crystallize in the orthorhombic crystal system in a primitive cell with space group Pna21.

Ternary silver argyrodites exhibit a wide range of properties and are classified as promising solid-state conductors, thermoelectrics, photovoltaic and nonlinear optical materials. This is ensured by the peculiarity of the crystal structure of argyrodites, which combines a rigid anionic and a disordered cationic sublattice. This work is devoted to the development of a technological regime for growing high-quality single-crystalline samples of Ag7+x(P1-xGex)S6 (x = 0.1; 0.25; 0.33) solid solutions by the method of directed crystallization from the melt. Polycrystalline alloys of Ag7+x(P1-xGex)S6 (x = 0.1; 0.25; 0.33) solid solution were obtained from previously synthesized ternary Ag7PS6 and Ag8GeS6. The synthesis was carried out by a single-stage and single-temperature method at a maximum temperature of 1010°C. The phase composition of the synthesized alloys was determined by the XRD method. Phase analysis of the obtained polycrystalline alloys did not reveal reflections of impurity phases. The results of thermal studies of Ag7+x(P1-xGex)S6 alloys were used to develop a technological regime for single crystals growth. Ag7+x(P1-xGex)S6 single crystal was grown from the melt by the directional crystallization method. As a result of the research, high-quality single crystals of Ag7+x(P1-xGex)S6 solid solutions (x = 0.1; 0.25; 0.33) were obtained. According to the results of X-ray diffraction, it was established that the solid solution of the composition Ag7.1(P0.9Ge0.1)S6 crystallizes in the primitive cubic cell of SG P213, and the solid solutions Ag7.25(P0.75Ge0.25)S6 and Ag7.33(P0.67Ge0.33)S6 crystallizes in a metastable at room temperature high-temperature modification with SG F-43m.

Published: May 2023

Global warming and biodiversity loss are critical issues, and forest retention and reforestation programs are crucial in mitigating climate change. However, discussions around these programs often exclude the role of urban vegetation in carbon sequestration. Preserving urban vegetation, such as trees, can also significantly reduce carbon emissions. Urban vegetation can be found in two main locations: Urban Green Open Spaces (UGS) and Road Landscapes (RL). In Denpasar Bali, Glodokan Tiang or Polyalthia longifolia trees are planted at those locations. Data management and carbon stock calculation mechanisms are required to demonstrate the contribution of urban vegetation in terms of carbon sequestration. The technology of Unmanned Aerial Vehicle (UAV) can be used as an alternative to efficiently calculate the estimated carbon stock. The calculation uses the Diameter Breast High (DBH) value approach using the canopy area and Canopy Height Model (CHM) obtained from UAV data processing using the Sfm method. UAV estimates show that the highest Above Ground Biomass (AGB) value at Bajra Sandhi Renon Field is 201.59 kg with a stored carbon content of 94.75 kg, while on I Gusti Ngurah Rai Bypass has the highest AGB value of 215.04 kg with a stored carbon content of 101.07 kg. These results have been validated by field observations, where the results of the regression analysis at the location of Bajra Sandhi Renon and I Gusti Ngurah Rai, show that between field observation data and estimation data with UAV there is no significant difference. While the results of the t-test: Paired Two Sample for Means at the Bajra Sandhi Renon Field and the Bypass I Gusti Ngurah Rai have a value above the significance level which proves that there is no significant difference between the carbon stock value from field observations and the carbon stock from the UAV approach.

Published: May 2023

Background
Cutaneous malignant melanoma is known to have a poorer prognosis in Asian patients as compared to Caucasians. Few studies have analysed the overall survival rate (OS) and melanoma-specific survival rate (MSS) of patients with cutaneous malignant melanoma in South Korea.

Aim
This study aims to analyse the OS, MSS and prognostic factors of patients with invasive cutaneous malignant melanoma in South Korea.

Methods
The medical records of patients diagnosed with invasive cutaneous malignant melanoma from July 2006 to June 2016 at Kyungpook National University Hospital were reviewed retrospectively. The OS/MSS of these patients were calculated in accordance with the Eighth American Joint Committee on Center staging system and the prognostic factors affecting MSS were analysed.

Results
A total of 202 patients with a mean age of 61.5 years were included. The 5-year OS/MSS was 64.4%/70.7% in the patients. The 5-year OS/MSS was 94.7%/97.1% for stage I, 67.2%/76.3% for stage II, 54.4%/59.1% for stage III, and 0%/0% for stage IV. On univariate analysis, the age, sex, Breslow thickness, ulceration, microsatellites, satellites, locally recurrent or in-transit metastasis, tumour metastasis in sentinel lymph nodes and clinicopathological stage were all significantly associated with the MSS, but not with acral distribution or BRAF mutation status. However, on multivariate analysis only the Breslow thickness, ulceration and stage IV were significantly associated with the MSS.

Limitations
This study was conducted retrospectively in a relatively small number of patients at a single tertiary center in South Korea.

Conclusions
The OS/MSS of patients with invasive cutaneous malignant melanoma in South Korea was lower than those in Caucasians. In addition to the Breslow thickness and ulceration, the impact of tumour location and sentinel nodal metastasis on cutaneous malignant melanoma should be reevaluated to better understand the disease prognosis in these patients.
Computed tomography-guided stereotactic surgery in the management of brain lesions: A single-center experience
Authors: Salah Mohamed , Shalaby Ahmed 
Published: May 2023

Background:
The present study presents our experience with computed tomography (CT)-guided stereotactic surgery in managing deep-seated brain lesions and provides a background in the expanding fields of morphological stereotactic neurosurgery.

Methods:
We conducted this retrospective cohort study on 80 patients managed at the Department of Neurosurgery, Zagazig University Hospitals, Zagazig, Egypt, between January 2019 to January 2021. We targeted patients with morphological stereotactic surgeries performed as the primary management modality of their treatment.

Results:
A total of 80 patients, with a mean age of 44.3 years, were included in the study. The stereotactic targets were supratentorial in 71 patients (88.75%), infratentorial in seven patients (8.75%), and both supraand infratentorial in two patients (2.5%). The lesions showed enhancements with IV contrast in 55 patients (68.75%). Stereotactic procedures were performed under local anesthesia in 64 patients and general anesthesia in 16 patients. Of the 80 stereotactic procedures, 52 were biopsies (65%). We observed a significant improvement in the postoperative Karnofsky performance score compared to the postoperative score (63.4 ± 19.8 vs. 56.7 ± 15.4, P = 0.001). The level of agreement between clinical, radiological, and final pathological diagnosis was assessed; it was complete in 47.5% of the patients. The postprocedural CT scan demonstrated intracranial hemorrhage in five patients (6.25%); four (5%) were silent with no neurological complications.

Conclusion:
This study provided evidence that the stereotactic procedure is easy to perform, accurate in targeting the lesion, and spares patients from undergoing major surgical procedures. Stereotactic applications of spontaneous intracerebral hemorrhage, deep-seated abscesses, encysted tumors, or medically refractory benign intracranial hypertension can improve the outcome even in medically high-risk patients.

We’ve studied the activation of persistent pathogenic microflora in 28 patients after retrograde pyelolithotripsy and the frequency of recurrence of kidney stones during the year under the conditions of traditional drug treatment in the early and late postoperative periods. We’ve studied the recurrence of kidney stones during the year under conditions of use in another group of patients (26 patients), in addition to traditional drug treatment, phytouroantiseptic (herbal extract BNO 1045). It has been confirmed that persistent pathogenic microflora is found in the structures of urinary stones, which is released after operative crushing of stones and reverses into active forms that are insensitive to the main groups of antibiotics, which long-term support a chronic inflammatory process in the kidneys, and is the cause of exacerbation of chronic pyelonephritis and relapse. It has been proven that the use of a phytouroantiseptic (herbal extract BNO 1045) in the complex treatment is the effective method for eliminating the infectious and inflammatory process in the kidneys caused by persistent pathogenic microflora, for decreasing the level of uric acid in the blood and normalization of urine’s pH, which leads to effective prevention of stone relapse.
