Authors: Miśkiewicz Piotr , Pelewicz-Sowa Maryla 
Published: February 2023

We present a case of severe thyroid storm with simultaneous hypercalcemic crisis resulting from excessive intake of 5% Lugol’s iodine solution (5% iodine, 15% potassium iodide, 85% water; 10 drops/day) and vitamin D3 (10000 IU/day) during 2 months of unconventional treatment in a 78-year-old female with a history of hyperthyroidism in course of Graves’ disease. Supplements were prescribed by herbalist/healer before admission to the hospital. At the clinic, we started therapy with antithyroid drugs, inorganic iodide and corticosteroids but without positive effect. Patient’s condition kept deteriorating with loss of consciousness. Plasmapheresis (4 procedures) was required to successfully reduce thyroid hormone levels and finally total thyroidectomy was performed resulting in postoperative hypothyroidism and transient hypoparathyroidism. Additionally, patient suffered from serious complications such as Takotsubo cardiomyopathy and sepsis requiring intensive care unit. Treatment with corticosteroids led to secondary adrenal insufficiency. Following 2-month hospitalization, patient was discharged in stable condition.
Price Competition in Five-Star Hotel Industry
Authors: Eko Atmadji  , Indra Putra Nugraha  
Published: February 2023

Purpose – To analyze the characteristics of price competition in five-star hotel industry in DIY.
Method – Descriptive qualitative method in order to know the detail about price competition. In-depth interviews with market players as well as government and other stakeholders are conducted. To get the full picture, this study also interviewed to PHRI (Indonesian Hotel Union). The SCP theory (structure-conduct-performance) becomes the guidance of interview and analysis.
Findings – The results of this study indicate that the hotel market is loose oligopoly or close to the monopolistic nature, competition is quite strict considering frequent over supply within one year, and pricing strategy becomes more important. Every hotel often changes their price strategy to follow certain conditions in the market. In differentiating its products, each hotel implements different themes to attract the attention of the guests. In five-star hotels at DIY, price strategy has low impact to the customers’ satisfaction except for Eastparc Hotel.
Implication – This study implicates that the behavior of five-star hotels in DIY will make the competition become soft and create tacit collusion. This is not good news for below three-star rank hotels.
Originality – This study contributes to the price competition study especially in five-star hotel market.

Abstrak
Tujuan – Menganalisis karakteristik persaingan harga pada industri hotel bintang lima di DIY.
Metode – Metode kualitatif deskriptif untuk mengetahui secara detail tentang persaingan harga. Wawancara mendalam dengan pelaku pasar serta pemerintah dan pemangku kepentingan lainnya dilakukan. Untuk mendapatkan gambaran yang utuh, penelitian ini juga mewawancarai PHRI (Persatuan Hotel Indonesia). Teori SCP (struktur-perilaku-kinerja) menjadi pedoman wawancara dan analisis.
Temuan – Hasil penelitian ini menunjukkan bahwa pasar perhotelan bersifat oligopoli longgar atau mendekati sifat monopolistik, persaingan cukup ketat mengingat sering terjadi over supply dalam satu tahun, dan strategi penetapan harga menjadi lebih penting. Setiap hotel sering mengubah strategi harga mereka untuk mengikuti kondisi tertentu di pasar. Dalam membedakan produknya, setiap hotel menerapkan tema yang berbeda untuk menarik perhatian para tamu. Di hotel bintang lima di DIY, strategi harga berdampak rendah terhadap kepuasan pelanggan kecuali Hotel Eastparc.
Implikasi – Studi ini berimplikasi bahwa perilaku hotel bintang lima di DIY akan membuat kompetisi menjadi lunak dan menciptakan tacit collusion. Ini bukan kabar baik untuk hotel peringkat bintang tiga atau lebih rendah.
Orisinalitas – Studi ini berkontribusi pada studi persaingan harga terutama di pasar hotel bintang lima.

Abstract

Grain sizes and minerals from Gulf of Tonkin sediments were evaluated from 30 surface samples and 50 samples in two cores, distribution of grain sizes and minerals to help understand sediment characteristics, origins, and environmental dynamics. There were five sediment types: Fine and very fine sands were found nearshore where land-sea interactions were stronger than offshore, whereas very coarse, coarse, and medium silts were found offshore, in small bays, river mouths with weak land-sea interactions, or near source sediment supplies. Minerals in sediment were identified as decreasing in the content of quartz, illite, kaolinite, chlorite, feldspar, goethite, halite, calcite, gibbsite, aragonite, and montmorillonite. Content of major minerals such as quartz, illite, kaolinite, and chlorite varied from nearshore to offshore; quartz was higher nearshore than offshore; illite, kaolinite, and chlorite nearshore were lower than offshore; calcite and aragonite were low nearshore and high in offshore; goethite was lower offshore and higher nearshore, while halite was high offshore and low nearshore. Surface sediments were divided into three groups based on sedimentary environment characteristics: group 1 was distributed nearshore with strong dynamics, group 2 in bays and nearshore with weak dynamics, and group 3 was distributed offshore with quiet dynamics. The origin of the sediments is weathering and erosion from the mainland and islands under the river and sea processes in the Gulf of Tonkin with quartz, illite, kaolinite, feldspar, chlorite and montmorillonite presenting in the sediment. Geochemical processes produced goethite, gibbsite, halite and pyrite in the sediments. Biological substances produced calcite and aragonite.
Frank-Read Mechanism in Nematic Liquid Crystals
Authors: Long Cheng , Deutsch Matthew , Angelo Joseph , Culbreath Christopher , Yokoyama Hiroshi , Selinger Jonathan , Selinger Robin 
Published: February 2023

Abstract
In a crystalline solid under mechanical stress, a Frank-Read source is a pinned dislocation segment that repeatedly bows and detaches, generating concentric dislocation loops. We demonstrate that in nematic liquid crystals, an analogous Frank-Read mechanism generates concentric disclination loops. Using experiment, simulation, and theory, we study a disclination segment pinned between surface defects on one substrate in a nematic cell. Under applied twist of the nematic director, the pinned segment bows and emits a new disclination loop which expands, leaving the original segment intact; loop emission repeats for each additional 180 degrees of applied twist. We present experimental micrographs showing loop expansion and snap-off, numerical simulations of loop emission under both quasistatic and dynamic loading, and theoretical analysis considering both free energy minimization and the balance of competing forces. Lastly, we discuss potential use of Frank-Read sources to modify microstructural evolution in both passive and active nematics.

Published: February 2023

Abstract
Objectives: This study aimed to evaluate and compare the efficacy of composite releasing Ca and PO4 ions versus conventional glass Ionomer, resin-modified glass Ionomer and hybrid composite regarding remineralization capacity and Microleakage.
Methods: thirty-four caries-free premolars were used, and class v cavities were prepared on each tooth. These teeth were divided into four groups and restored with the following materials : (Resin-modified glass Ionomer RMGI, Glass Ionomer GI, Hybrid composite HC, Tetracalcium phosphate composite TTCP). Sixteen teeth were stored in demineralized solution for two days then examined by SEM. All treated teeth were stored in a glass bottle in artificial saliva of pH 7 at 37oC for periods 30 days then examined by SEM. Two specimens used as a baseline. 16 teeth were sectioned longitudinally in a buccolingual direction through the middle of restoration after immersed in 1% methylene blue solution for 24h, observation for marginal leakage was done under Stereomicroscope at 10X.
Results SEM micrographs of group glass-ionomer showed almost normal enamel surface with numerous mineral deposits. The resin-modified glass-ionomer showed enamel surface exhibits almost normal appearance and has minute mineral deposits. The hybrid composite showed enamel surface irregularities and slight separation between enamel and restoration and Tetracalcium phosphate TTCP showed almost normal enamel surface that occluded by numerous mineral deposits.
Conclusions: Tetracalcium phosphate composite and resin-modified glass ionomer, are highest marginal sealing than either hybrid composite and conventional glass-ionomers. Tetracalcium phosphate composite, are more effective at remineralization capacity than other groups.

Published: February 2023

Abstract
Objective
The aim of this study was to assess the quality and reliability of YouTube videos on ectopic pregnancies for the public.
Method
We searched for the key terms “ectopic pregnancy”, “ectopic birth” and “extra uterine pregnancy” on YouTube. Each video that met the inclusion criteria was analyzed by two independent raters. Quantitative and qualitative metrics were recorded, and the videos were scored using the DISCERN instrument.
Results
A total of 37 videos met the inclusion criteria. The mean overall DISCERN score was 44.5 ± 15.6. Videos had significantly a higher DISCERN score if they contained explanations on anatomy (pvalue < 0.01), physiopathology (p-value < 0.01), diagnosis (p-value = < 0.01), treatments (p-value < 0.01), symptoms (p-value < 0.01), clear information (p-value < 0.01), animations (p-value < 0.01) and if it was a physician speaking (p-value < 0.01).
Conclusion
YouTube videos on ectopic pregnancy have been assessed to be only fairly reliable. We identified the five best ones using the validated DISCERN instrument. While ectopic pregnancy is not uncommon, YouTube videos should be improved to provide more accurate information for the public.

Abstract
Storage phosphors displaying defect emission are indispensable in technologically advanced radiation dosimeters. The current dosimeter is limited to the passive detection mode, where ionizing radiation-induced deep-trap defects must be activated by external stimulations, such as ultraviolet light or heat. Herein, we designed a new type of shallow-trap storage phosphor by controlling the dopant amounts of Ag+ and Bi3+ in the host lattice of Cs2NaInCl6. A distinct phenomenon of X-ray-induced emission (XIE) is observed for the first time in an intrinsically nonemissive perovskite. The intensity of XIE exhibits a quantitative relationship with the accumulated dose, enabling a real-time radiation dosimeter. Thermoluminescence and in situ X-ray photoelectron spectroscopy verify that the emission originates from radiative recombination of electrons and holes associated with X-ray-induced traps. Theoretical calculations reveal the evolution process of Cl-Cl dimers serving as hole trap states. Analysis of temperature-dependent radioluminescence spectra provides evidence that the intrinsic electron-phonon interaction in 0.005Ag+@Cs2NaInCl6 is significantly reduced under X-ray irradiation. Moreover, 0.025Bi3+@Cs2NaInCl6 shows an elevated sensitivity to the accumulated dose with a broad response range from 0.08 Gy to 45.05 Gy. This work discloses defect manipulation in halide double perovskites, giving rise to distinct shallow-trap storage phosphors that bridge traditional deep-trap storage phosphors and scintillators and enabling a brand-new type of materials for real-time radiation dosimetry.

Published: February 2023

Abstract
This study aimed to investigate the effect of PSP (Pomegranate Seed Pulp) on rumen fermentation, digestibility, and methanogens and protozoa population (by competitive PCR) of the camel and goat rumen fluid. Treatments included 0, 5 and 10% PSP replaced wheat bran. Rumen fluid was collected from 3 goats and 2 camels according to the similarity of sex, breed, origin and time and used for three gas production tests. DNA extraction was performed by RBB + c method, band intensities (target and competing DNA) were calculated by the ImageJ program and line gradients were plotted based on the number of copies and intensity. Diets had no significant effect on methanogen and protozoa population (P < 0.05), but Based on numerical counting, diet containing 5% PSP reduced the microbial population. Animal species affected microbial populations so that both populations in camels were less than goats (P < 0.05). The production of gas and volatile fatty acids was not affected by diets. These two parameters and NH3 concentration and methane production in goats were higher than camel (P < 0.05). The pH digested dry matter and microbial protein in camels were higher than in goats (P < 0.05). Therefore, the competitive PCR technique is an effective method for the enumeration of Rumen microbiota. Dietary supplementation with pomegranate seed pulp can modify the methanogen and protozoa population, reduce methane production and increase microbial protein will improve the animal's energy resources and feed protein. This supplementation can be considered as a strategy to achieve performance and environmental benefits.
