Organic photovoltaic (OPV) are a promising new class of photovoltaic as they offer several advantageous features including large surface area to volume ratio, low cost, lightweight properties, and durability. The limitation of OPV that prevented their adoption for use in the past was their low power conversion efficiency (PCE) but that drawback has been solved by the development of the donor-acceptor-donor (D-A-D) system with high conversion efficiencies. Herein, 5-(2-ethylhexyl)-1,3-di (furan-2-yl)-4H-thieno [3,4-c]pyrrole-4,6(5H)-dione (FTPF), a donor-acceptor-donor monomer was investigated for its optoelectronic, excited state, and photovoltaic properties using a density functional theory (DFT) and time-dependent density function theory (TD-DFT) at the B3LYP/6-31+G(d,p) theoretical method. The spectral analysis (FT-IR, UV-vis, and NMR), electronic molecular properties, natural bonding orbitals (MOs and NBOs) analyses, and excitation were studied at this level in gas, hexane, DMF, and THF. The UV-Vis spectrum showed that FTPF exhibited mono-absorption in non-polar gas and hexane, but dual absorptions in polar solvents (DMF and THF) having maximum wavelength (λmax) at 351, 359, 371 and 373 nm in gas, hexane, THF, and DMF respectively, showing a major red shift as solvent became polar. The hole-electron excitation studies of the first five singlet states: S0→S1/S2/S3/S4/S5 in gas and DMF phases showed that S0→S1 is a delocalized π→π* Rydberg excitations originating from the D-A-D C=C π bonds, S0→S2 is π→π* local excitation, while S0→S3 in water occurred as an n→π* from the carbonyl and azolide groups of the acceptor unit, but n→π* charge transfer (CT) in DMF. The S0→S5 in water and S0→S4 are n→π* LE type excitations, while S0→S5 in DMF conformed to a delocalized π→π* excitation extended over the D-A-D conjugated backbone. FTPF provided efficient electron injection in all studied solvent; showing that FTPF is a sure-bet for opto-electronic application.

Authors: Bin Wang , Jianping Chen , Jian Ouyang
Published: October 2021

Background/Objective:
To establish and validate an individualized nomogram to predict the probability of death within 30 days in patients with sepsis would help clinical physicians to make correct decision.
Methods
We collected data of 1,205 patients with sepsis. These included 16 indexes like age and blood, randomly assigned to the modeling and verification groups. In the modeling group, the independent risk factors related to death within 30 days were analyzed. Besides, a nomogram was established to draw the receiver-operating characteristic (ROC) curve of the subjects. Subsequently, the discriminant ability of the model was evaluated by the area under the ROC curve (AUC). Then, a calibration chart and Hosmer-Lemeshow test were employed to evaluate the calibration degree of the model, and the Decline Curve Analysis (DCA) test was used to evaluate the clinical effect of the model.
Results
The different independent risk factors related to the death of sepsis patients within 30 days included pro-brain natriuretic peptide (pro.bnp), albumin, lactic acid (lac), oxygenation index, mean arterial pressure (map), and hematocrit (hct). The AUC of the modeling and verification groups were 0.815 and 0.806, respectively. Moreover, the P-values of the Hosmer-Lemeshow test in the two groups were 0.391 and 0.100, respectively, and the DCA curves of the two groups were both above the two extreme curves.
Conclusion
Our model presents good significance for predicting the death of sepsis patients within 30 days. Therefore, there is a need to implement this model in clinical practice, as prompt prediction could help tailor treatment regimens and enhance survival outcomes.

Published: October 2021

Background: Multiple morphological abnormalities of the sperm flagella (MMAF) is a subtype of severe asthenoteratozoospermia with poorly understood genetic etiology. SPAG6 is a core axonemal component that plays a critical role in the formation of cilia and sperm flagella. Previous studies have reported that mutations in SPAG6 cause primary ciliary dyskinesia (PCD), but the association between SPAG6 gene variants and the MMAF phenotype has not yet been described.Methods: We performed whole-exome sequencing (WES) in two unrelated Han Chinese men with MMAF. Sanger sequencing was used to validate the candidate variants. Routine semen analysis was carried out according to the WHO guidelines (5th Edition). Sperm morphology was assessed using modified Papanicolaou staining. Scanning and transmission electron microscopy (S/TEM) was performed to observe the ultrastructural defects of the sperm flagella. Western blot analysis and immunofluorescence (IF) of spermatozoa were performed to examine the expression of SPAG6 protein. Assisted fertilization with intracytoplasmic sperm injection (ICSI) was applied. Results: Two homozygous SPAG6 variants were identified by WES and Sanger validation in two patients with MMAF phenotype (F1 II-1: c.308C>A, p. A103D; F2 II-1: c. 585delA, p. K196Sfs*6). Semen analysis showed progressive rates of less than 1%, and most of the spermatozoa presented MMAF by Papanicolaou staining. TEM revealed that the overall axonemal ultrastructure was disrupted and primarily presented an abnormal “9+0” configuration. No other PCD-related symptoms were found on physical examination and medical consultations, as well as lung CT screening. The level of SPAG6 protein was significantly decreased in the spermatozoa, and IF analysis revealed that SPAG6 staining was extremely weak and discontinuous in the sperm flagella of the two patients. Notably, F1 II-1 and his wife conceived successfully after undergoing ICSI.Conclusions: Our research provides new evidence for a potential correlation between SPAG6 variants and the MMAF phenotype.

Published: October 2021

Planetary habitability, as we experience on Earth, is linked to a functioning geodynamo which is in part driven by the crystallization of the liquid iron-nickel-alloy core as a planet cools over time. Cosmochemical considerations suggest that sulfur is a candidate light alloying element in rocky planetary cores of varying sizes and oxidation states; such that, iron sulfide phase relations at extreme conditions contribute to outer core thermochemical convection and inner core crystallization of a wide range of planetary bodies. Here we experimentally investigate the structural properties of the Fe-S system and report the discovery of the sulfide, Fe5S2, crystallizing in equilibrium with iron at Earth’s outer core pressures and high temperatures. Using single-crystal X-ray diffraction techniques, Fe5S2 was determined to adopt the complex Ni5As2-type structure (P63cm, Z = 6). These results conclude that Fe5S2 is likely to crystallize at the interface of Earth’s core and mantle and will begin to crystallize during the freezing out of Earth and Venus’ core overtime. The increased metal-metal bonding measured in Fe5S2 compared to the other high P-T iron sulfides may contribute to signatures of higher conductivity from regions of Fe5S2 is crystallization. Fe5S2 could serve as a host for Ni and Si as has been observed in the related meteoritic phase, perryite, (Fe, Ni)8(P, Si)3, adding intricacies to elemental partitioning during inner core crystallization. The stability of Fe5S2 presented here is key to understanding the role of sulfur in the multicomponent crystallization sequences that drive the geodynamics and dictate the structures of Earth and rocky planetary cores.
How Does Green Credit Policy Affect Total Factor Productivity at the Corporate Level in China: The Mediating Role of Debt Financing and the Moderating Role of Financial Mismatch
Authors: Feng Yanchao , Shen Qiong
Published: October 2021

Taking the “Green Credit Guidelines” issued in 2012 as a quasi-natural experiment and employing the A-share listed enterprises scanning from 2008 to 2020 as the research sample, this study has investigated the impact of green credit policy on total factor productivity at the corporate level in China, with the consideration of the mediating role of debt financing and the moderating role of financial mismatch. The findings are as follows: (1) green credit policy has effectively and directly promoted total factor productivity at the corporate level in China; (2) the mediating role of debt financing is merely supported for the full sample and the state-owned sample; (3) the moderating role of financial mismatch is merely established via codirectionally moderating the negative impact of green credit policy on debt financing for the full sample and the eastern sample; (4) the non-state-owned enterprises’ dilemma of difficult and expensive debt financing is proved. The conclusions and policy implementations are provided in the last section to highlight the practical and theoretical significance of this study.

Non-Ceruloplasmin Copper as a Stratification Biomarker of Alzheimer’s Disease Patients: How to Measure and Use It
Authors: Squitti Rosanna , Ventriglia Mariacarla , Granzotto Alberto , Sensi Stefano L. , Rongioletti Mauro Ciro A.
Published: October 2021

Alzheimer’s Disease (AD) is a type of dementia very common in the elderly. A growing
body of recent evidence has linked AD pathogenesis to Copper (Cu) dysmetabolism in the body. In
fact, a subset of patients affected either by AD or by its prodromal form known as Mild Cognitive
Impairment (MCI) have been observed to be unable to maintain a proper balance of Cu metabolism
and distribution and are characterized by the presence in their serum of increased levels of Cu not
bound to ceruloplasmin (non-ceruloplasmin Cu). Since serum non-ceruloplasmin Cu is a biomarker
of Wilson's Disease (WD), a well-known condition of Cu-driven toxicosis, in this review, we
propose that in close analogy with WD, the assessment of non-ceruloplasmin Cu levels can be exploited
as a cost-effective stratification and susceptibility/risk biomarker for the identification of
some AD/MCI individuals. The approach can also be used as an eligibility criterion for clinical
trials aiming at investigating Cu-related interventions against AD/MCI.
Interaction Influence of Contact Time and pH on Cobalt Retention by
Carbon Nanotubes Bearing Various Loads of TiO2 and Fe3O4
Authors: Fasfous Ismail , El-Sheikh Amjad , Awwad Anas , Al-Degs Yahya , Dawoud Jamal
Published: October 2021

Background: Nanomaterials have facilitated remarkable advances in the remediation of
many environmental problems. A few studies have tackled the removal of Co (II) from aqueous
solutions using nanomaterials. Herein, we studied the retention kinetics of cobalt species on carbon
nanotubes (CNTs) bearing different amounts of TiO2 and Fe3O4 nanomaterials individually.

Methods: CNTs and their TiO2/Fe3O4-modified nanomaterials were well characterized. Cobalt
retention by these adsorbents was investigated considering different influencing factors such as Co
(II) content, solution pH, and time. The kinetic data were fitted with pseudo-first-order, pseudosecond-
order rate models, and intra-particle diffusion models for better elucidation of the mechanism
of Co retention.

Results: XRD evidenced the formation of TiO2 and Fe3O4. High loads of both oxides were needed
for higher and faster Co retention by CNTs. Co retention capacity increased with increasing the
solution pH. The pseudo-second-order model presented the kinetics of Co retention at 30 oC, and
48% of available capacity was attained within the first hour of interaction by CNT-TiO2 and with a
moderate S/L ratio of 0.5 g/L. Co retention was increased with the amount of oxide to reach a maximum
value of 16. 40 mg/g (90.2% TiO2) and 13.60 mg/g (48.2% Fe3O4). The Jovanović equilibrium
model predicted the maximum retention values as the nearest to the experimental ones.

Conclusion: The potential of CNT-Fe3O4/TiO2 nanomaterials has been successfully demonstrated
for the removal of cobalt, which makes them highly attractive and cost-effective adsorbents for
wastewater treatment. The reported retention and removal rate values were relatively better than
those seen in the literature. Loading different active oxides by CNTs is an interesting research area
as selective adsorbents can be fabricated with affordable experimental costs.

Published: October 2021

The given work is devoted to the experimental proof of existing the spontaneous spin polarization of the donor electron system of 3d-transition element impurity atoms of low concentration (<1 at.%) in a mercury selenide crystal. For this purpose there have been measured the dependences of the magnetization on the magnetic field strength. As a result of the analysis of the obtained dependences, there were extracted the impurity contributions, which are described by the magnetization curves typical of the ferromagnets, and by the magnetic parameters conforming to the spontaneous magnetism of the systems under study, which are unambiguously related to the donor conduction electrons of the outer d-shells of impurity atoms. By its nature, according to the developed theoretical concepts, the spontaneous spin polarization manifests itself in exchange interaction, taking place in hybridizing the electronic states of the impurity atom and the conduction band ones of the crystal.

Complexes of metals with Schiff bases are considered as promising materials for creating energy storage and photovoltaic devices. In this work, the semiconducting properties of a polymer nickel film with a salen-type ligand (poly-Ni(CH3O-Salen)) were studied by spectrophotometric and Faraday impedance spectroscopy. The Mott-Schottky analysis showed that the polymer film is a semiconducting material with a fairly narrow band gap, high charge carrier density and p-type conductivity. Using the method of Faraday impedance spectroscopy, the limiting stage of the oxygen photoelectroreduction reaction, the process of charge transfer from the film to molecular oxygen, has been established.

Authors: Moon Khatiya C , Van Meter Anna R , Kirschenbaum Michael A , Ali Asra , Kane John M , Birnbaum Michael L
Published: October 2021

Background

Little is known about the internet search activity of people with suicidal thoughts and behaviors (STBs). This data source has the potential to inform both clinical and public health efforts, such as suicide risk assessment and prevention.

Objective

We aimed to evaluate the internet search activity of suicidal young people to find evidence of suicidal ideation and behavioral health–related content.

Methods

Individuals aged between 15 and 30 years (N=43) with mood disorders who were hospitalized for STBs provided access to their internet search history. Searches that were conducted in the 3-month period prior to hospitalization were extracted and manually evaluated for search themes related to suicide and behavioral health.

Results

A majority (27/43, 63%) of participants conducted suicide-related searches. Participants searched for information that exactly matched their planned or chosen method of attempting suicide in 21% (9/43) of cases. Suicide-related search queries also included unusual suicide methods and references to suicide in popular culture. A majority of participants (33/43, 77%) had queries related to help-seeking themes, including how to find inpatient and outpatient behavioral health care. Queries related to mood and anxiety symptoms were found among 44% (19/43) of participants and included references to panic disorder, the inability to focus, feelings of loneliness, and despair. Queries related to substance use were found among 44% (19/43) of participants. Queries related to traumatic experiences were present among 33% (14/43) of participants. Few participants conducted searches for crisis hotlines (n=3).

Conclusions

Individuals search the internet for information related to suicide prior to hospitalization for STBs. The improved understanding of the search activity of suicidal people could inform outreach, assessment, and intervention strategies for people at risk. Access to search data may also benefit the ongoing care of suicidal patients.
How Food Marketing on Instagram Shapes Adolescents’ Food Preferences: Online Randomized Trial
Authors: Bragg Marie , Lutfeali Samina , Greene Tenay , Osterman Jessica , Dalton Madeline
Published: October 2021

Background

Worldwide obesity rates have prompted 16 countries to enact policies to reduce children’s exposure to unhealthy food marketing, but few policies address online advertising practices or protect adolescents from being targeted. Given adolescents spend so much time online, it is critical to understand how persuasive Instagram food advertisements (ads) are compared with traditional food ads. To strengthen online food marketing policies, more evidence is needed on whether social media ads are more persuasive than other types of ads in shaping adolescents’ preferences.

Objective

This study examined whether adolescents could identify food companies’ Instagram posts as ads, and the extent to which Instagram versus traditional food ads shape adolescents’ preferences.

Methods

In Part 1, participants aged 13-17 years (N=832) viewed 8 pairs of ads and were asked to identify which ads originated from Instagram. One ad in each pair was selected from traditional sources (eg, print; online banner ad), and the other ad was selected from Instagram, but we removed the Instagram frame—which includes the logo, comments, and “likes.” In Part 2, participants were randomized to rate food ads that ostensibly originated from (1) Instagram (ie, we photoshopped the Instagram frame onto ads); or (2) traditional sources. Unbeknownst to participants, half of the ads in their condition originated from Instagram and half originated from traditional sources.

Results

In Part 1, adolescents performed worse than chance when asked to identify Instagram ads (P<.001). In Part 2, there were no differences on 4 of 5 outcomes in the “labeled ad condition.” In the “unlabeled ad condition,” however, they preferred Instagram ads to traditional ads on 3 of 5 outcomes (ie, trendiness, P=.001; artistic appeal, P=.001; likeability, P=.001).

Conclusions

Adolescents incorrectly identified traditional ads as Instagram posts, suggesting the artistic appearance of social media ads may not be perceived as marketing. Further, the mere presence of Instagram features caused adolescents to rate food ads more positively than ads without Instagram features.

Abstract: Coming from a flourishing nation like India, Farming and Agriculture is the main source of income the recent stats shows it is about still IOT and application of automation and handheld devices engages an imperative role towards greatness and amelioration of the country. During these present times there have been some previous old methods being used in farming which have many limitations and also very demanding in terms of human labour and have to go out for supervision and check for any intruders or alerts or even to spray water. These conventional process have recurring costs and more demanding sometimes false human alarms or even a false crop information as a result substantial damages are foreseen hence it increases the costs and burden over the farmer. It has been observed that in some cases where farmers are cooperating with the technological advancements which are available in the present era have benefited from its fruitful outcome. The aim of this paper is to develop a smart farm supervision and protection system which comes in handy for getting regular farm alerts on a smart phone the alerts can be changed in the form of a text message or even an automated phone call hence the additional feature of this model is the improvement of crop growth according to different seasons and weather.

Study for Improvement in the Surface Properties and Wear Behavior of Mild Steel
Authors: Nahvi Hamdan Gowhar
Published: October 2021

Abstract: Surface of a material can be improved by depositing the filler metal for the enhancement of various properties. Surface should be harder than substrate material for surface improvement. This surface improvement is also known as surfacing. In present research Mild steel specimens of size 140×35×40 were used to deposit surfacing layers and study the feasibility of iron/aluminum with varying compositions on low carbon steel deposited by GTAW process. Specimens for hardness and oxidation resistance were prepared. While studying oxidation of surfaced and un-coated area (base material), oxidation test resulted that the oxidation occurred on surface of base metal (un-coated area) after heating at different temperatures and time intervals. Specimens kept at 500˚C, 700˚C temperatures for 3, 6, 9 hours to get oxidized from un-coated surface but no mark of oxidation and pitting was visible at surfaced area but pitting of un-coated area occurred at 700˚C temperature. Oxidation had no effect to surfaced area. Low temperature oxidation test specimens gave only weight loss from un-coated portion but high temperature oxidation gave high amount of weight reduction due to pitting occurred on un-coated portion. The amount of weight loss of specimens increased with increase in furnace holding time at constant temperature. With increase in temperature oxidation of un-coated area of specimens also increased and pitting action occurred on un-coated area of specimens at high temperature. Further, for the various wear tests the cylindrical pins of 8 mm diameter with spherical tip 4 mm radius was made. Wear tests were carried out on pin on disc sliding wear testing machine. The comparison of wear rate loss was studied with constant sliding distance, varying load and sliding velocity of different compositions of iron/aluminum surfacing and substrate material. Hardness and wear resistance of composition were increased with increase in percentage of Fe element in composition. Composition C1 (Fe:Al/70:30) had high hardness and high wear resistance as compared to composition C2 (Fe:Al/30:70) and C3 (Fe:Al/50:50). Composition C3 (Fe:Al/50:50) had better hardness and wear resistance as compared composition C2 (Fe:Al/70:30). Keywords: Surface improvement, Fe-Al intermetallic, GTAW process, Sliding wear.
Blast Loading and Its Effects on Building
Authors: Chaurasiya Mohini
Published: October 2021

Abstract: Terrorist assaults have become more common in recent years. Their main purpose is to destroy important structures such as areas of defense, hospitals, schools, buildings. Due to the explosion, high pressure is generated and the blast time is also very short, but it can damage the structure from outside and inside. Which can cause a lot of damage to human life. There has an influence on the nation's economy. Like the earthquake and wind load, the blast load should also be designed, keeping in mind the important structures that have to be avoided from the explosion. In this research paper, six story R.C.C. Structures exposed to explosion loads are analyzed. We study the effect on the building by changing the weight of the explosive and the distance between the explosion source and the building. The IS 4991-1968 code has been used to calculate the parameters of the explosion pressure waves. The program ETabs 2019 has been used to analyze the effect of blast load. The structure has been modified by providing shear walls to reduce excessive displacement due to blast loading on the building. The results of the analysis are compared after adding the shear wall with the general building model. The result was that after the addition of the shear wall, the effect of blast loading is greatly reduced.

So far, APTI has carried out various ways and strategies so that national-scale regulations can be changed or removed. In addition to tobacco control regulations, there are also classes of tobacco farmers in Temanggung to give birth to local capitalization and make the tobacco trade chain longer.
La expresión del malestar en Chile: cultura, esfera pública y luchas sociales
Authors: Del Valle Orellana Nicolás
Published: October 2021

This article develops the concepts of the public sphere, cultural malaise and social suffering in critical theory to think of social struggles as forms of social protest and political protest that occurred since October 2019 in Chile. The article explores the thesis on social discontent, which maintains that recent social struggles are a public expression of the unrest cultivated by processes of social modernization. According to the author, beyond the normative justification in reasons and arguments regarding the conditions of injustice that affect the agents in struggle, the social critique emerges from the social suffering that finds its place in the materiality of the discourses, images and bodies in the public sphere.
A Philosophical Defense of Ecological Sensitivity in the Business World
Authors: Sachdev Kumar Neeraj
Published: October 2021

An attempt is made in the paper to analyze the nature of virtue of ecological sensitivity to argue for its relevance and need in the business world. Ecological sensitivity is a virtue or quality of a human being to relate himself to the environment in a protective spirit of oneness. It is not a virtue by extension from human to environment like compassion or empathy but a virtue of independent normative standing since it is argued to be equal to other personal and inter-personal virtues in the pool of virtues to live a good human life. It is further argued that since ethics is a study of values and virtues to live a good human life and business companies are a great source to sustain and improve upon the state of mankind in the world and the condition of planet earth itself, it makes sense to emphasize the need to include ecological sensitivity as a virtue in the conduct of business professionals. It also attempts to understand how the business professionals ought to interpret ecological sensitivity in and around their surroundings on a daily basis.

Silent is a beautiful powerful boost of positive energy and it is an important aspect of worship. Our mind is moving towards past and future. Bringing mindfulness into the present time during our materialistic society of hectic lives silent evolved as a relief mode for relaxation and happiness. World Health Organization and the European Commission’s Joint Research Centre concluded that a steady dose of noise pollution could lead to higher blood pressure and fatal heart attacks. It was the result of the research found that high rates of cholesterol and hypertension in individuals regularly exposed to loud noises at work. In this situation silence can actually stimulate new cell growth in the brain, improve memory, and release tension in the brain and body. In fact, two minutes of silence is more effective in relieving physical tension than listening to relaxing music.

El techo de cristal es un concepto que define la dificultad que encuentran las mujeres para acceder a ciertas posiciones en el sector laboral. De forma habitual se comprueba cómo cuanto más se asciende en la escala de puestos directivos menor es la presencia de mujeres debido a que su carrera se trunca durante su vida laboral antes de tener la oportunidad de avanzar hacia puestos elevados. La industria cinematográfica es un sector que no parece escapar a esta lógica de desigualdad y, por eso, el presente estudio se ocupa de analizar la presencia de las mujeres en un certamen tan relevante como los premios Oscar concedidos por la Academia de las Artes y las Ciencias Cinematográficas. Se ha priorizado la elección de este ejemplo sobre otros debido a la relevancia internacional del certamen como referencia de la industria del cine a nivel mundial, además de la disponibilidad de información que ofrece la entidad. La metodología empleada está basada en un enfoque cuantitativo y cualitativo de revisión de fuentes documentales y análisis de datos obtenidos de bases de datos de acceso abierto. Los resultados procesados y codificados muestran como las mujeres se encuentran infrarrepresentadas en la concesión de premios en el ejercicio de la profesión audiovisual a pesar de que las cifran tienden a aumentar conforme pasan los años.

The stock price changes at any time within seconds. The stock price is a time series data. Thus, it is necessary to have the best analysis model in predicting the stock price to make decisions to avoid losses in investing. In this research, the method used two models Deep Learning namely Long Short Term Memory (LSTM) and Gated Recurrent Unit (GRU) in predicting Indonesia Composite Stock Price Index (IHSG). The dataset used is historical data from the Jakarta Composite Index (^JKSE) stock price in 2013-2020 obtained through Yahoo Finance. The results suggest that Deep learning methods with LSTM and GRU models can predict Indonesia Composite Stock Price Index (IHSG). Based on the test results obtained RMSE value of 71.28959454502723 with an accuracy rate of 92.39% for LSTM models and obtained RMSE value of 70.61870739073838 with an accuracy rate of 96.77% on GRU models.
Fish and Fisheries in Floodplain Swamp in Middle Part of Musi River
Authors: Muthmainnah Dina , Gaffar Abdul Karim
Published: October 2021

Floodplain area is a very dynamic water system where the influence from terrestrial and river is high. This area is recognized as feeding, nursery and spawning ground of some fishes. Capture fisheries in this area is frequently occurred by using some of specific fishing gears which related to dynamic pattern of aquatic environment, such as water level, current, and physical-chemical aspects of water. The research was conducted in order to evaluate fish caught composition and fishing activity in floodplain swamp in middle part of Musi River by survey method. The result showed that 45 species of fish were caught and nine kinds of fishing gears were used by fishers. Gill nets were used in whole year, while seine were used only in the peak of dry season. Intra-annual variations of swamp water flow can modify the distribution and migratory pattern of fish species, with direct effects on fish catches.

Published: October 2021

To investigate the potential of adsorption and regeneration of natural pumice from West Sumatera Indonesia for total chromium (Cr) removal from aqueous solution, batch experiments in multiple adsorption-desorption cycles were performed. The results indicated that the optimum condition of total Cr removal were 3 of pH solution, 0.3 g/L of adsorbent dose, 60 min of contact time of adsorption, <63 ?m of diameter of adsorbent, and 1 mg/L of total Cr initial concentration with 2.226 mg Cr/g pumice of total Cr uptake. The experimental data obtained were fitted with the Freundlich adsorption isotherm within the concentration range studied. Desorption efficiencies for total Cr ions by using 0.1 M HCl as desorbing agent were in the range of 31-32%. Although complete desorption were not attained, the natural pumice could be sufficiently reused up to 3 cycles of adsorption- desorption with increasing trend in total Cr uptake that may due to the surface modification of natural pumice caused by HCl. Overall results revealed that easy availability of natural pumice as local mineral in West Sumatra, Indonesia and its ability to adsorb and retain total Cr will create more interest to develop new natural adsorption method of pollutant removal from solution.

PT BaturonaAdimulya is a coal mining company located in BabatSupatSubdistrict, MusiBanyuasin Regency, South Sumatera Province. Based on the calculation of overburden digging volume at Pit 2 with progress survey that is measurement using total station sokkia set 3010 instrument and the processing and calculation using surpac 6.5.1 result in overburden volume or cover ground 251,941 BCM. Coal mining in open pit will cause environmental changes, either small hills or mined holes (voids). The burden removing from Pit 2 by backfilling method in the mining area will minimize the voids that occur. PT BaturonaAdimulya has void in Pit 1 as large as 4.8 Ha, and will do backfilling that requires overburden material as much as 295.721 BCM / Ha and top soil as much as 33,600 LCM / Ha. The voids left at the end of the mine without any utilization planning have the potential to cause undesirable impacts on the environment. Therefore, PT BaturonaAdimulya is planning to revegetate the void area so it can be utilized and become a green field again as before.

Epidural steroid injections of the lumbar spine are a common interventional procedure that is used to alleviate radicular pain resulting from degenerative changes in the spine. Although several studies have compared epidural steroid injections with placebo with favorable outcomes, randomized controlled trials in this direction are needed. The purpose of the study was to evaluate the effectiveness of the use of epidural steroid injections in the treatment of pain in patients with degenerative lesions of the lumbar spine. During the study, 262 patients with degenerative lesions of the spine at one or two levels of the vertebral-motor segment (VMS) were selected. Epidurally transforaminally under fluoroscopic control all patients received steroid injections at the appropriate level (s) of VMS on the basis of the rehabilitation department of the Institute of Traumatology and Orthopedics of the National Academy of Medical Sciences of Ukraine during 2017-2019. Of the 262 patients who received epidural steroid injections, 204 were able to reduce pain and avoid surgery within one year. However, 58 patients experienced only slight pain relief and were recommended surgical treatment. In our study, patients with negative results were offered surgery after 1.98 ESI procedures with an interval of 3.7 months. In the group of operated patients, the preliminary use of steroid injections did not bring relief by the results of Oswestry Disability Index (ODI) and Visual Analog scale (VAS), however, the condition of these patients improved significantly after surgery (p<0.05). The use of epidural injections is possible as a first-line therapy in patients with moderate functional limitations, which can subsequently be directed to surgery in the absence of a positive result.
