Abstract. In Iran, a significant percentage of agricultural soils are contaminated with a range of potentially toxic elements (PTEs), including Ni, which need to be remediated to prevent their entry into the food chain. Silicon (Si) is a beneficial plant element that has been shown to mitigate the effects of PTEs on crops. Biochar is a soil amendment that sequesters soil carbon and that can immobilize PTEs and enhance crop growth in soils. No previous studies have examined the potentially synergistic effect of Si and biochar on the Ni concentration in soil chemical fractions and the immobilization thereof. Therefore, the aim of this study was to examine the interactive effects of Si and biochar with respect to reducing Ni bioavailability and its corresponding uptake in corn (Zea Mays) in a calcareous soil. A 90 d factorial greenhouse study with corn was conducted. Si application levels were 0 (S0), 250 (S1), and 500 (S2) mg Si kg−1 soil, and biochar treatments (3wt %) including rice husk (RH) and sheep manure (SM) biochars produced at 300 and 500 °C (SM300, SM500, RH300, and RH500) were utilized. At harvest, the Ni concentration in corn shoots, the Ni content in soil chemical fractions, and the release kinetics of DPTA (diethylenetriaminepentaacetic acid)-extractable Ni were determined. Simultaneous utilization of Si and SM biochars led to a synergistic reduction (15 %–36 %) in the Ni content in the soluble and exchangeable fractions compared with the application of Si (5 %–9 %) and SM (5 %–7 %) biochars separately. The application of Si and biochars also decreased the DPTA-extractable Ni and Ni content in corn shoots (by up to 57 %), with the combined application of SM500 + S2 being the most effective. These effects were attributed to the transfer of Ni in soil from more bioavailable fractions to more stable iron-oxide-bound fractions, related to soil pH increase. SM500 was likely the most effective biochar due to its higher alkalinity and lower acidic functional group content which enhanced Ni sorption reactions with Si. The study demonstrates the synergistic potential of Si and SM biochar for immobilizing Ni in contaminated calcareous soils.

Published: July 2024

The current research was an attempt to explore the association between Job Satisfaction (JS) and Locus of Control (LOC). The gender difference in JS and LOC was also explored. For this study a sample of 421(211 males, 210 females) mid-career employees was drawn from Karachi, Pakistan. It was hypothesized that (1) Internal LOC will be positively correlated with JS. (2) There will be gender difference in JS, and (3) there will be gender difference in LOC. The first hypothesis of the study was proved. Results indicated that there is positive correlation between JS and internal LOC however the gender difference is insignificant in both, JS and LOC in the sample under study (i.e., mid-career employees of Karachi, Pakistan). The findings of current study offer valuable insights into the factors that impact JS, providing practical recommendations for organizations looking to enhance employee engagement and productivity.

Re-examination of the Khar khoroot inscription
Authors: Tsend Battulga 
Published: July 2024

The inscriptions of Khar Khoroot, Bayanbürd Bag, Buutsagaan Sum, Bayankhongor Province, were re-examined. A few characters and letters were inadvertently copied. There is a single line of inscription in the Khar Khoroot that says, yätmis apa on bašï bitidim ~ I, the corporal, wrote for Yetmish Apa”. Except for Khar Khoroot, none of the Mongolian runic monuments have intentionally drawn boundaries. The inscription on Khar Khoroot is unique in this regard. Upon the demise of a nobleman named Yätmis Apa, an inscription was crafted in his honor. The framing of the inscription might serve as a symbolic indication of its intended purpose for a funeral. Depicting deceased individuals through the use of frames and fences is a prevalent practice in human societies, serving as a universal emblem and symbol throughout cultures. Put simply, Yetmish Apa, who died while traveling, was unable to construct a sacrificial complex due to lack of chance or time. As a result, they were burned, and a commemorative inscription was made. The absence of any other stamp associated with the Turkic and Uighur periods on the Khar Khoroot rock indicates that the scribes had a brief presence and only inscribed on specific occasions. Chronologically, it is clear that the Khar Khoroot inscription belongs to the Uighur period.

EFL Teachers’ Voices in Differentiated Instruction
Authors: Yuniawati Deonisia Tyas 
Published: July 2024

Abstract:
All children in Indonesia have an equal right to education at their level, and the curriculum acknowledges the diversity of Indonesian classrooms. Teachers must consequently incorporate this into the design of their lesson plans. In order to give students alternative possibilities for obtaining information, differentiated instruction involves rearranging classroom instruction and learning methodologies. Teachers may be familiar with the idea of varied education, but they frequently struggle to incorporate difference in terms of content, method, and output in their classrooms. In the framework of differentiated education, this thesis investigates the points of view and experiences of EFL (English as a Foreign Language) teachers.
The purpose of this study is to hear these teachers' voices as they discuss the opportunities and difficulties that varied education methodologies in various classroom contexts bring. The study highlights the perspectives of EFL teachers on how differentiated instruction should be implemented. The results show how different educational approaches, assessment methods, and classroom management strategies are used by teachers to meet the various learning demands of their students.
The study reveals the struggles and obstacles faced by EFL teachers as they attempt to strike a balance between the demands of a standard curriculum and the particular needs of each of their students. It also underlines how important professional development is in giving teachers the abilities and information required for successfully implementing differentiated instruction. The study's conclusion emphasizes the importance of administrative policies, administrative support systems, and teamwork in determining the overall success of courses for differentiated instruction.

Поглощение раствора при бурении нефтяных и газовых скважин является одним из самых распространенных осложнений, возникающих в процессе, которое может стать причиной существенного увеличения затрат времени. Целью данной работы явилось создание условий для снижения скорости поглощения бурового раствора при бурении нефтегазовых скважин. Облегченная буровая, промывочная жидкость была получена путем добавления в рецептуру глинистого раствора полимерных реагентов, модифицированных омыленными гудронами вакуумной дистилляции жирных кислот хлопкового масла. Приведены результаты структурных исследований полимерного реагента, полиакриламида, модифицированного хлопковым гудроном на основании данных ИК-спектроскопии. По результатам полученных спектральных характеристик полимерных композиций сделано предположение о строении образовавшегося комплекса, обладающего набухающими свойствами, что снижает скорость проникновения в поры пустых пород, и тем самым способствует «уходу» раствора в затрубное пространство скважины.

ObjectiveUsing polysomnography, the gold standard for sleep assessment, this study aimed to describe the objective prevalence of insomnia in the São Paulo, Brazil, Epidemiologic Sleep Study cohort of 1,101 adults (20–80 years old).MethodsObjective insomnia was defined by meeting 1 of the following criteria: sleep onset latency >30 minutes (sleep initiating insomnia), wake after sleep onset lasting >30 minutes (sleep maintenance insomnia), total sleep time <360 minutes and a terminal wakefulness >30 minutes (insomnia with too short duration of sleep or early morning awakening), or a combination of the previous quantitative criteria (mixed disorder). Using validated questionnaires based on Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM‐IV) criteria, subjective insomnia was categorized into 3 groups: good sleepers, insomnia symptoms, and DSM‐IV insomnia.ResultsA total of 1,042 subjects participated in the study (95% response rate). The prevalence of objective insomnia was 32%. The subjective prevalence of insomnia symptoms was 45%, and the subjective prevalence of DSM‐IV insomnia was 15%. Sociodemographic factors were similar in both the objective insomnia and the DSM‐IV insomnia groups. Age, but not psychiatric symptoms, was predictive of objective insomnia. The subjective criteria were not adequately sensitive (36%) to identify objective insomnia, but were adequately specific (77%) to rule out polysomnography noninsomnia.InterpretationThe prevalence of objective insomnia assessed by polysomnography was higher than the prevalence of subjective insomnia according to DSM‐IV–validated questionnaires.

Evaluation of olefinic block copolymer blends with amorphous polyolefins—effect of different unsaturated and saturated hydrocarbon tackifier resins on blend miscibility
Authors: Raja P. Rajesh , Wilson J. K. , Peters M. A. , Croll S. G. 
Published: May 2013

ABSTRACTBlends of ethylene–octene based olefinic block copolymer (OBC) with two amorphous polyolefin (APO) polymers [atactic propylene homopolymer (PP) and ethylene–propylene copolymer (PE–PP)] were evaluated at three different ratios. Dynamic mechanical analysis (DMA) and transmission electron microscopy (TEM) evaluations were performed to determine the blend miscibility characteristics. Viscoelastic properties of both OBC blends with PP polymer, and OBC blends with PE–PP copolymer showed incompatibility. Analysis revealed that both blends formed two phase morphologies. The effect of three unsaturated aliphatic hydrocarbon resins with varying aromatic content and two saturated hydrocarbon resins with different chemistries were evaluated as compatibilizing agent for OBC/PP and OBC/PE–PP blends. A 1 : 1 polymer blend ratio of OBC/PP and OBC/PE–PP was selected to better understand the influence of resin addition at three different levels 20, 30, and 40 wt %. The fully aliphatic unsaturated resin seems to improve the miscibility of the OBC/PP blends at higher resin addition levels, but reduced the miscibility as the aromatic content of the resin increases. However, OBC/PE–PP blends showed improved miscibility with increasing aromatic content. A ternary phase morphology was particularly observed for both OBC/PP and OBC/PE–PP blends with highly aromatic (14%) unsaturated hydrocarbon resin, in which OBC formed the continuous phase, and PP, PE–PP, and unsaturated hydrocarbon resins formed the dispersed phase. Interestingly, we did not observe much difference in miscibility characteristics between the two saturated resin chemistries in both blend systems (OBC/PP and OBC/PE–PP). The Harkins spreading coefficient concept was used to better understand the ternary blend dispersed phase morphology. Spreading coefficients indicate that the free hydrocarbon resins (both unsaturated and saturated) were encapsulated by the amorphous PP or amorphous PE–PP polymer in the dispersed phase for the respective blend compositions. Overall OBC–PP and OBC/PE–PP blends showed better miscibility characteristics with both saturated aliphatic hydrocarbon resins, irrespective of the difference in resin chemistries. © 2013 Wiley Periodicals, Inc.

Published: May 2013

ABSTRACTSelf‐emulsified water‐borne epoxy curing agent of nonionic type was prepared using triethylene tetramine (TETA) and derivative of epoxy resin as a capping agent, which was synthesized by liquid epoxy resin (E51) and polyethylene glycol (PEG), and the curing agent possessed emulsification and curing properties at the same time. The curing agent with good property of emulsifying liquid epoxy resin could be obtained under the condition of the molar ratio of PEG : E51 : TETA as 0.8 : 1 : 3.5 at 80°C for 5 h. The mean particle size of the emulsion liquid was about 220 nm with the prepared curing agent and epoxy resin at the mass ratio of 1 : 3. The structure of the emulsion‐type curing agent was confirmed by FTIR and 1H NMR spectra, and the mechanism of cured film formation was also analyzed by SEM photographs. The cured film prepared by the emulsion‐type curing agent and epoxy resin under ambient cure conditions showed good properties even at high staving temperature. This study provides useful suggestions for the application of the water‐borne epoxy resins in coating industry. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 130: 2652–2659, 2013
Influences of extractant on the hydrophilicity and performances of HDPE/PE‐b‐PEG blend membranes prepared via thermally induced phase separation (TIPS) process

Published: May 2013

ABSTRACTBlending the block copolymer into the membrane matrix is a convenient and efficient way for membrane modification. In this study, HDPE/PE‐b‐PEG membranes were prepared via TIPS process, and the extractant effect was investigated. An interesting finding was that a non‐polar extractant (n‐hexane) was more conducive to the surface enrichment of PEG chains than a polar solvent (ethanol). The reason was deemed to be the combined effect of entropy drive, interfacial energy, and the swelling behavior. Besides, membrane performances related to the surface chemical properties were studied. Results suggested that the prepared blend membranes extracted by n‐hexane showed enhanced hydrophilicity, anti‐fouling property and water flux. © 2013 Wiley Periodicals, Inc. J. Appl. Polym.
