Mercury Contamination of Water and the Removal of Mercury from Water
Authors: Wen Jiayue
Published: January 2023

Mercury is a common element in nature. Mercury that is in compound form does not severely harm the environment and human being. However, when the mercury element is by itself, that is when its oxidation state is zero, it easily gets into the air or the water. And because the mercury is not in any compound form, nothing restricts its toxicity, it affects the environment and people’s health. Both anthropogenic reasons and natural factors lead to the mercury contamination in water. Coal combustion, zinc smelting, gold rushing, and mercury mining are the major anthropogenic reasons. And since mercury naturally exists in the nature, natural soil would release mercury, which then goes into water as rainwater or flows pass by. Removing mercury from water has been a focus in many places like Guizhou, China and Peru. Ion exchange resins adsorption and multifunctional chitosan non-woven fabrics modified with carbon dots (CDs) can be used. Ion exchange resins adsorption includes a wide variety of substrate. And with these binding agents, mercury, along with many other heavy metal ions, can be easily adsorbed. CDs are carbon nanoparticles that exhibit high sensitivity and good ability to fluoresce, With the modification with CDs, fabrics can change into a cheap and easy tool to remove mercury from water. Studying the removal of mercury contamination from water helps reduce gradual damage to the environment and to human bodies.

Published: January 2023

The reinforced concrete structure has the advantages of strong stability, small shrinkage and creep, but there are still some hidden structural dangers in reality. This study introduces the background of stability analysis, takes a truss bridge as an example, uses Monte Carlo simulation and COMSOL Multiphysics software to analyze structural stability, and finds out the relevant factors affecting the stability of the truss. Through calculations and comparison of hundred thousand simulations, the stability of the bridge is one of the most critical elements of a bridge and meets the criteria for bridge performance. In particular, the strength and elasticity of the concrete and steel reinforcement at high temperatures were analyzed. Results show that aggregate type, mixing ratio, curing conditions, heating parameters, and cooling state all contribute subtly to the properties of concrete. High temperature causes the concrete and steel strength decreasing, but normal living temperatures do not pose any threat to bridge structures. For elongation, the effect of temperature on the reinforcement is not obvioust.

Authors: Liao Junhan
Published: January 2023

Accurate failure probability is essential in structural reliability analysis. Plenty of methods utilized to calculate the failure probability are proposed. Monte Carlo Simulation (MCS) is one of the typical methods for solving this kind of engineering problems. In recent years, M5Tree algorithm has begun to be applied in this domain and shown great potential. The paper expounds the principles and the truss-reliability analysis process of both MCS and M5Tree through two truss examples. While evaluating the reliability using MCS, the random variables from uncertain aspects are simulated to gain the failure probability directly. In the M5Tree+MCS method, input datasets are used to generate the performance function to obtain the probability. The results indicate that MCS has great operability and practicability in dealing with general engineering problems while its computational efficiency is unsatisfactory compared to M5Tree algorithm +MCS. Overfitting in M5Tree algorithm always happens and affects the analysis on testing data, a defect of M5Tree. The accuracy of failure probability and computational efficiency are the main criterions for judging.

Essa ave apareceu após uma forte tempestade, e sua ocorrência pode ter relação com isso, ou poderia estar fazendo algum deslocamento regional, comportamento já observado em outros ralídeos. Devido ao baixo número de registros desta espécie para o litoral paulista, este relato pode ajudar a entender melhor sua ocorrência nesta região do estado de São Paulo, contribuindo com sua conservação.
Use of a Heli-FX System Guide steerable sheath for internal iliac artery bridging stent re-intervention following iliac branch procedure via a contralateral	femoral approach

Endovascular aneurysm repair (EVAR) offers lower early morbidity and mortality at the expense of increased long-term re-intervention. Dilatation of distal landing zones is increasingly managed with iliac branch procedures. Re-intervention for endoleak from the internal iliac artery (IIA) bridging stent component is usually approached from arm access due to concerns regarding inducement of displacement of the EVAR caused by traversing the neobifurcation of the stentgraft from contralateral groin access. We present a novel case of successful re-intervention for IIA endoleak in the setting of previous fenestrated repair using the Heli-FX System Guide steerable sheath.

Businesses in the livestock sector which are part of the agricultural business sector are very vulnerable to economic and social impacts. Price fluctuations and currency exchange rates will be felt by breeders, as well as people’s purchasing power which will greatly affect the livestock business sector. Population growth causes a region’s Gross Regional Domestic Product (GRDP) to change. The purpose of this study was to analyze the effect of economic growth and population on the welfare of breeders. This research method uses a quantitative approach that emphasizes the analysis of numerical data processed by statistical methods and literature study. The literature study is related to macroeconomic indicators, namely the population and welfare of breeders. Secondary data uses data from the Subang Regency Livestock and Animal Health Service, the West Java Province Food Security and Livestock Service Office, the Central Bureau of Statistics (BPS) Subang Regency, and West Java BPS as well as data from related journals and articles. Data analysis using multiple regression analysis techniques. The results showed that there was a significant influence between economic growth and population on the welfare of breeders in Subang Regency. This research shows that the welfare of smallholder breeders is influenced by economic growth and population. The higher the economic growth and population of an area, the higher the level of welfare of breeders in that area.

In this study, we aimed to determine whether the presence and duration of diabetes mellitus (DM) is ‎associated with changes in intervertebral disc degeneration, epiphyseal plaque degeneration, and ‎subcutaneous fat tissue thickness. Diabetic patients and non-diabetic participants (control group) who applied to the ‎internal medicine outpatient clinic between 2020-2022 and had lumbar spine magnetic resonance imaging ‎due to low back and/or leg pain were included the study. Disc degeneration, epiphyseal plaque ‎degeneration, and subcutaneous fat tissue thickness parameters of DM patients and control group were ‎reviewed retrospectively, and the results were statistically evaluated. There were 80 DM patients in the ‎patient group, 25 (31.3%) of these patients were male and 55 (68.8%) were female. There was a total of ‎‎121 participants in the control group, of which 39 (32.2%) were male and 82 (67.8%) were female. The ‎mean age of the patient group was 57.85±10.76 years, while the mean age of the control group was ‎‎54.23±13.09 years. There was no significant difference between the duration of DM and disc degeneration, ‎epiphyseal plaque degeneration, and subcutaneous adipose tissue thickness. However, there was a ‎significant difference between the control group and the DM patient group in terms of disc degeneration and ‎epiphyseal plaque degeneration (p=0.003 and p=0.017, respectively). This study reveals that patients with ‎diabetes have an increased susceptibility to disc degeneration and epiphyseal plaque degeneration, ‎regardless of disease duration. Control and treatment of diabetic disease will make an important contribution ‎to the prevention of secondary complications‎.

Objective: This study aimed to determine the adenovirus genotypes and their epidemiological features between January 2018 and November 2019, in Istanbul, Turkey. Material and Methods: Conjunctival swab samples were obtained from patients who were clinically diagnosed with keratoconjunctivitis. Samples were screened with an Adeno Detector kit (Rapid Pathogen Screening, RPS Inc., South Williamsport, PA). Nucleic acid extraction and amplification were performed with the ADENOVIRUS ELITe MGB® kit in the ELITe In Genius instrument (Elitech Group, Torino, Italy). For subtyping of the strains, sequencing primers targeted the ‘Hypervariable Region 7’ (HVR-7) of the hexon gene were used. DNA sequence analysis (n:72) was performed with ABI PRISM® 3100 Genetic Analyzer (Applied Biosystems, USA), and subtyping was done by BLAST analysis. Results: The median viral load in the samples (n: 77) was 7 log10 copies/mL (IQR: 4.5-7.4 log10 copies/mL). The clinical finding score was found to be significantly higher in the high viral load group (Adenovirus DNA≥6 Log 10 copies/mL) than in the low viral load group (Adenovirus DNA
The effects of mean platelet volume and red cell distribution width on prognosis in patients with myelodysplastic syndrome
Authors: AYHAN Ihsan , ERTOP Sehmus
Published: January 2023

Objective: In this study, the relationship between changes in mean platelet volume (MPV) and erythrocyte distribution width (RDW)

with hematological response and survival in patients with myelodysplastic syndrome was investigated.

Patients and Methods: Between 1 January 2011 and 31 December 2018, patient characteristics and hemogram results were evaluated

during the treatment process among 158 patients diagnosed with myelodysplastic syndrome.

Results: The mean age of the patients who were included in the study was 71.53±12.6 years. The MPV percentage change in the 2-year

follow-up of the patients with and without hematological response was significant, at 0.022±0.11 (2.2%) in those who responded and

at 0.069±0.15 (6.9%) in those who did not (p=0.049). Throughout the same period, the degree of RDW changes in the patients who

died was 13.23±22.97, the degree in those who survived was 2.86±21.42, and the difference between the two groups was statistically

significant (p=0.006).

Conclusion: In patients diagnosed with myelodysplastic syndrome, MPV and RDW values can be considered inexpensive and simple

laboratory markers that can be used in follow-ups and promising tests to predict both treatment response and survival in the early

period and change treatment modalities.
