Published: January 2024

This work was aimed at synthesizing a number of new complex compounds, nitrification inhibitors containing Zn2+, and determining their structure, composition and biological activity. Four substances with different ratios of ligands (4-amino-1,2,4-trazole (ATC)) and dicyandiamide (DCD)) were synthesized. Some physicochemical properties were determined, such as thermal behavior and solubility of complexes in pure KAS-28 (a saturated solution of urea and ammonium nitrate containing 28% nitrogen) and its 50 % solution. The content of Zn2+ in each substance was determined. The functional groups belonging to the ligands were established using IR spectroscopy. It was established that the attachment of ATC in solution takes place monodentately to one zinc atom through the N1 atom, and in crystals it occurs bidentately to two zinc atoms through the N1 and N2 atoms (1, 2-coordination). The attachment of DCD, most likely, proceeds through the C=NH group. The level of biological activity of complex compounds was determined by the potentiometric method. A direct measurement of the concentration of NH4+ and NO3– ions was carried out. The greatest influence on the nitrification process was found in the complex with the following probable empirical formula [Zn(ATC)2(DCD)1(H2O)1]SO4. When using it, the smallest loss of ammonium and the smallest formation of nitrates in the soil were observed. This indicates the influence on both stages of nitrification.

The interaction of ions with water was considered using the example of alkali metal cations with a common hydroxyl anion. Structural and energetic changes in the ion-dipole system of water were analyzed. A significant influence of the size of the cations on the change in the interaction energy and the polarizability (dielectric permeability) of water around the ion was shown. In this case, at the boundary with the lithium ion, the dielectric constant was close to 1, and at the boundary with the cesium ion, it increased to 1.67. The dielectric constant at the boundary of the first hydrate shell for lithium and cesium ions increased to 2.1 and 2.25, respectively, corresponding to the experimentally obtained value given in the literature. An analysis of energetic and steric factors affecting the amount of ions hydration was carried out. Lithium was shown to have two shells consisting of 4 and 8 dipoles of water, corresponding to primary (positive) hydration. A significant value of the ion-dipole bond energy made it possible to consider the hydrated ion as a quasi-solid particle. The effect of hydrated ions on the water viscosity was calculated using Einstein formula. Two opposite factors were shown to affect the viscosity during hydration: the presence of quasi-solid particles increased the viscosity, and the existence of a secondary hydrated shell with broken bonds between water molecules decreased it. Satisfactory correspondence between theoretically calculated and experimentally determined viscosity values was obtained.

In order to compare the kinetic characteristics of the heat treatment of starches and solve the question of what has a greater influence on the processes of their dextrinization, the chemical composition or their botanical origin, we carried out research by using methods of thermogravimetry and differential scanning calorimetry. It was shown for the first time that there is a process with heat absorption at 1300C in the temperature range of 25–2000C, in addition to the stages of dehydration of starches, which is not accompanied by a decrease in weight. This endoeffect is well explained by the melting process of the low-molecular amylose fraction of starches. In contrast to literature data, it was also established that the stage of starch decomposition in the temperature range of 200–3500C should be considered as a set of three consecutive processes. It was established that the activation energies of dehydration processes of pre-dehydrated starches are equal to 60 kJ mol–1. The average activation energy аor the stages of destruction of starches is 400–500 kJ mol–1. Such values of the activation energy of starch destruction processes are explained by the presence in their composition of a number of semi-crystalline subcomponents characterized by different thermal stability. When comparing the values of the activation energies of the dehydration and dextrinization processes of the investigated starches, a linear correlation was established for the first time, which testifies to the uniformity of such processes and their independence from the botanical origin of the starches.

Cyclic voltammetry and electrochemical impedance spectroscopy were used to study the effect of pH and the Co:Rut ratio on redox potentials and electrical conductivity of water-alcohol solutions of Co(II) complexes with rutin (Rut). It was found that the reduction potentials for the ratio Co:Rut=1:1 and 1:2 are in the range of –0.110 V to –0.197 V relative to the Ag/AgCl reference electrode, which is significantly higher than the potentials for known flavonoids. In an alkaline medium, the absolute value of the reduction potential increases regardless of the composition of the sample. The measured range of oxidizing potentials for all compounds is in the range of +0.02 V to +0.094 V relative to Ag/AgCl reference electrode, which corresponds to the potentials of compounds with self-oxidizing activity. It is assumed that an increase in oxidative potentials up to 0.094 V can characterize the antioxidant activity, which is associated with the manifestation of the autoxidizing properties of the complex in the presence of oxygen and is due to the participation of different binding sites in chelation with the metal. Using the data of electrochemical impedance spectroscopy, the capacity of electrical double layer of a platinum electrode in water–alcohol solutions containing Co(II) complexes with rutin was calculated. An increase in capacitance values by an order of magnitude was observed at a ratio of metal:ligand=2:1 in comparison with the complexes having a ratio of 1:1. The effect of an excess of hydroxyl ions on the charge distribution at the electrode/solution interface was experimentally established, leveling the effect of the Co:Rut ratio on the electrochemical properties.

The effectiveness of protecting a structural steel by cationic inhibitor against biocorrosion caused by Desulfovibrio sp. М-4.1, Desulfomicrobium sp. TC 4, and sulfidogenic microbial communities was investigated by using gravimetric and electrochemical methods. The research showed that at a concentration of 1 g/l, the inhibitor offers greater protection to steel St3ps against Desulfomicrobium sp. TC 4 (up to 81.0%) than to Desulfovibrio sp. М-4.1 (up to 72.2%). The structure of the molecules of the inhibitor's compounds determines their ability to form a protective layer on the surface of the metal and exhibit antimicrobial action to sulfate-reducing bacteria and their satellites (iron-reducing bacteria). The inhibitor provides a high degree of protection (>92.9%) in microbial corrosion under the influence of sulfidogenic microbial communities. The cationic inhibitor was shown to have a greater effect on the electrochemical performance of the corrosion process for the biofilm form of sulfate-reducing bacteria than for the planktonic form.

The purpose of this study was to establish a correlation between the effect of the pollutant content on the dimensional and physicochemical characteristics of the investigated solutions and its effect on aquatic organisms. To this end, the surface tension, electrical conductivity, pH, and redox potential of aqueous solutions of sodium dodecylbenzenesulfonate were measured in a wide concentration range (10–710–2 М). The change in the size and number of optical inhomogeneities was investigated using the small-angle reflection method in the micron range. In addition, the behavior of aquatic biological objects (Daphnia Magna) was studied in the investigated solutions. It was shown that the investigated concentration dependences (including the behavior of biological objects) are non-linear: they have either a stepped character or clearly expressed extremes and are well correlated with each other. A comfortable concentration range of sodium dodecylbenzenesulfonate for daphnia (all daphnia are active within 58 hours of the experiment) was established (0.018–0.037 mM). The correlation and nature of the concentration dependences indicate that at critical concentrations, structural rearrangements occur in sodium dodecylbenzenesulfonate solutions, not only the formation of micelles and pre-micelles, but also structural rearrangements of the solvent (water) itself. Thus, it has been experimentally shown that the change in the structure of water during interaction with pollutants can significantly affect both the physicochemical properties of aqueous solutions and the behavior of aquatic biological objects.

Background and Aims Blood flow restriction (BFR) training has been suggested as an effective method to improve muscle hypertrophy and for rehabilitation. The present study aims to investigate the effect of resistance training (RT) with BFR on serum levels of sirtuin-1 (SIRT-1), visfatin, and nitric oxide (NO) in elite male athletes after anterior cruciate ligament (ACL) reconstruction. Methods Twenty elite male athletes voluntarily participated in the study and were randomly divided into two groups of RT-BFR (n=10) and RT (n=10). Subjects in both groups participated in 12 weeks of RT at an intensity of 30-70% of 10-repetition maximum (2-4 sets). The subjects in the RT-BFR group performed resistance training by placing a blood pressure cuff in the upper thigh with a pressure of 120-180 mm Hg. Blood samples were collected before and 48 hours after the last training session to measure serum levels of blood markers. Data analysis was done by the analysis of covariance (ANCOVA) and paired t-test. P<0.05 was considered statistically significant. Results Twelve weeks of RT-BFR significantly increased serum levels of SIRT-1 (P<0.001(, visfatin (P=0.02), and NO (P=0.01) in the post-test phase, compared to the pre-test phase. Furthermore, the between-group analysis results showed that RT-BFR significantly increased serum levels of SIRT-1 (P<0.001) and NO (P=0.002) compared to the RT group. Conclusion The RT combined with BFR can increase the serum concentrations of SIRT-1 and NO in elite athletes after ACL reconstruction, compared to the RT alone

Background and Aims The importance of participatory health governance has been acknowledged by the World Health Organization. Studies have shown the positive effects of participation in occupation-based intervention in patients with severe mental disorders, including schizophrenia, in outpatient and inpatient wards. The purpose of this article is to review the studies on occupation-based interventions in patients with severe mental disorders. Methods This is a narrative review study. A search for related articles was conducted in PubMed, Google Scholar, Cochrane, ScienceDirect, Scopus, OTseeker, PsycInfo databases using the keywords “severe mental disorder”, “serious mental illness”, “schizophrenia”, “Major depression disorder”, “Bipolar disorder”, “Occupational therapy”, Occupation”, and “Occupation-based intervention” without the time limitation. Titles and abstracts of 480 yielded articles were examined. Results Twelve articles were reviewed; Two were related to occupation-based interventions in psychiatric inpatients, five were related to occupation-based interventions in outpatients, and five were related to occupation-based interventions in both inpatients and outpatients. Among these articles, one studied the challenges of using occupation-based interventions. Conclusion It seems that occupation-based interventions in inpatients and outpatients with mental illness have been used more to reduce symptoms, and less attention has been paid to the effectiveness of these interventions in maintaining and or improving occupational performance in these patients. The Canadian model of occupational performance and the recovery framework have been used in the design of these interventions. To achieve better results in psychosocial rehabilitation where occupation-based interventions lead to an increase in quality of life, the challenges in this area should be solved.

Background and Aims Adolescent idiopathic scoliosis (AIS) is one of the spinal deformities with unknown causes that contributes to 80-85% of scoliosis cases. This study aims to evaluate the effect of an integrative corrective exercise program on the severity of scoliosis in girls with AIS. Methods This is a quasi-experimental study with a pretest/posttest/follow-up design. Thirty-two girls (Mean age: 13.97±2.25 years; mean height: 153.97±7.978 cm, mean weight: 52.03±6.23 kg) with AIS (C-shaped thoracic deviation in the frontal plane) participated in the study. They were randomly divided into the exercise and control groups. The Cobb angle was measured by the radiography method. All measurements were performed before, immediately after, and 12 weeks after the exercise. Multivariate analysis of variance was used to examine within-group differences, and analysis of covariance was used for between-group differences. Results The mean Cobb angle at the pre-test, post-test, and follow-up phases were 15.8, 16.60, and 16.85 degrees in the control group and 16.04, 11.26, and 11.01 degrees in the exercise group, respectively, indicating a significant improvement in the Cobb angle in the exercise group compared to the control group over time (P<0.05); this improvement maintained for 12 weeks. Conclusion The integrated corrective exercise program, by using selected exercises, can reduce the degree of Cobb angle in females with AIS. The use of this program is recommended for adolescents.

Background and Aims Nowadays, lifestyle changes have led to non-structural musculoskeletal disorders. Various methods are used to correct these disorders, such as techniques with a local perspective on the disorder and its correction and techniques focused on the cerebral cortex. This study aims to review the studies that have addressed the role of the cerebral cortex, postural awareness, and used methods in correcting postural disorders. Methods In this review study, the search was conducted for relevant papers published from 2005 to 2020 in Scopus, PubMed, ScienceDirect, Google Scholar, SID, and Academic Search. Of 70 papers found in the initial search, 20 met the inclusion and exclusion criteria and were reviewed. Results In the present study, Some studies examined the cortical map and body representation in the brain (BRIB), muscle behavior, and movement patterns and suggested a reciprocal relationship between BRIB and muscle behavior. According to some studies, the inconsistency of BRIB with the actual state of the body led to improper control of posture and, consequently, poor posture. Some other studies suggested a relationship between postural awareness and muscle dysfunction, followed by poor posture. Conclusion Although studies have acknowledged the role of the cerebral cortex and body representation (Homunculus) in correcting and achieving an optimal posture, there are lack of studies on the techniques for improving this representation and its effect on correcting postural abnormalities.

Background and Aims Several studies have investigated gait biomechanics in people with functional ankle instability (FAI). However, the potential role of information processing (attention) in the gait control of these patients is still unknown. Therefore, this study aimed to investigate the effect of cognitive load on the range of motion (ROM) of lower limb joints during walking in men with and without FAI. Methods The study was a non-randomized controlled clinical trial. Eighteen male subjects with FAI and 19 healthy subjects participated in this study and completed three randomized conditions (three trials per condition): normal walking on a treadmill (single task), normal walking while performing a cognitive task (dual task), and (3) performing cognitive task while sitting. Three-dimensional information of hip, knee, and ankle joint ROM in the sagittal, frontal, and transverse planes were measured as gait kinematic components, and the error ratio and average reaction time were measured as cognitive task indicators. The intraclass correlation coefficient (ICC) was used to determine the intrasession reliability of kinematic and cognitive measures. Results The ICC of kinematic variables, including the hip, knee, and ankle joint ROM, with and without applying cognitive tasks in three planes was more than 0.70. During the single task, the group with FAI showed a significantly decreased knee ROM in the transverse plane and a decreased hip ROM in the sagittal plane compared to the healthy group. During the dual task, the group with FAI showed a significantly increased hip ROM in the sagittal plane compared to the healthy group. The results of the cognitive task showed that the group with FAI had a longer reaction time in the auditory Stroop test during dual-task walking than in the sitting position. Conclusion FAI can be an important factor in motor-cognitive interactions. Using a cognitive task may be an effective strategy in the rehabilitation program of men with FAI.

Background and Aims Genu varus is one of the most common lower limb deformities that can affect a person’s daily activities and sports performance. This study aims to investigate the effect of the 8-week use of knee braces on the electrical activity frequency of muscles in men with genu varus during walking. Methods This is a quasi-experimental study on 30 male college students with genu varus (aged 20-30 years) who were randomly divided into control and intervention groups. Corrective exercises were performed for 8 weeks using knee braces in the intervention group. The electrical activity of selected muscles was recorded by an electromyography system. For statistical analysis, ANCOVA was used. The significance level was set at 0.05. Results During the loading phase, the results showed a lower frequency of biceps femoris muscle in the intervention group compared to the control group (P=0.041). The frequency of muscles did not show any significant difference between groups in the mid-stance and push-off phases (P>0.05). Conclusion Given the decrease in the frequency of biceps femoris muscle activity in men who used knee braces, it can be concluded that the 8-week use of these brace can be effective in reducing shock absorption in the lower extremity.

Background and Aims The use of medical insoles is one of the non-surgical treatment methods for improving the gait pattern of individuals with leg length discrepancy (LLD). However, the long-term effect of insoles on lower limb joint dynamics in these individuals is still unclear. This study aims to investigate and compare the long-term effect of inner and outer insoles on selected dynamics variables of the lower limb joints in men with LLD during the stance phase of gait. Methods This is a randomized clinical trial with a pre-test/post-test design on 18 men with mild LLD, randomly divided into two parallel groups of inner insole and outer insole. Selected dynamics parameters were measured by six cameras and a force plate during the stance phase of gait. Both groups used the insole for 12 weeks for at least four hours per day. Repeated-measures ANCOVA was used to test the hypothesis. P≤0.05 was statistically significant. Results After 12 weeks of using insoles, the peak lateral pelvic tilt decreased significantly in the inner insole group (P=0.041 for short leg, and P=0.008 for long leg) and outer insole group (P=0.026 for short leg, P=0.007 for long leg). The peak knee abduction moment (P=0.022 for inner insole, P=0.007 for outer insole) and peak hip abduction moment (P=0.006 for inner insole, P=0.005 for outer insole) also decreased significantly. In the outer insole group, the peak anterior pelvic tilt showed a significant change in the post-test stage compared to the pre-test stage (P=0.014 for short leg, and P=0.033 for long leg). There was no significant difference between the two groups in the selected dynamics variables (P>0.05). Conclusion The long-term use of inner and outer medical insoles, by causing a change in the lower limb joint dynamics, can lead to a positive adaptation in men with mild LLD. There is no significant difference in the long-term effect of inner and outer insoles.

Differences in personality types significantly influence learning processes and outcomes, including problem-solving skills. This research aims to describe numeracy problem-solving skills among eleventh-grade students in the science group, focusing on the DISC personality types. The study, conducted in Kediri, West Java, Indonesia, involves two representatives for each personality type. The research utilizes the DISC personality test by William Moulton Marston, a numeracy problem-solving assessment consisting of three problems, and an interview guideline. Data accuracy is ensured through source and technique triangulation, along with member-checking to validate interview results. The findings reveal that students with dominance personality types generally follow a four-step numeracy problem-solving process, occasionally skipping the re-checking step for specific questions. Influence personality types also exhibit a four-step approach to numeracy problem-solving. In contrast, students with steadiness personalities accurately describe four levels of problem-solving to achieve correct results. Compliance personality types, while adhering to a four-step process, encounter inaccuracies in certain problem solutions. In summary, students with different personality types consistently undergo a four-step numeracy problem-solving process, but variations arise in the final outcomes of problem-solving.

The evaluation of the Independent Curriculum (Kurikulum Merdeka) is currently underway, employing various methods such as the Minimum Competency Assessment (Asesmen Kompetensi Minimum [AKM]). AKM assesses general yet fundamental competencies, including numeracy skills. This assessment method endeavors to delineate students' numeracy skills within the context of website-based learning. Employing a descriptive qualitative method, the study involves 20 eighth-grade students from a Junior High School in Ciamis, West Java, Indonesia. Students are instructed to access a website developed by the researchers, featuring study materials and example problems. Throughout the learning activities, students utilize the Google Meet video conferencing application, activating their cameras for interactive sessions. Following the lesson, students undergo a numeracy skills test comprising validated questions. The research outcomes unveil three distinct levels of numeracy skills among students: high, medium, and low. Those with high-level numeracy skills demonstrate proficiency in mathematical numeracy skills indicators but exhibit errors in applying formulas. Conversely, students with moderate and low mathematical numeracy skills commonly struggle with concept comprehension, identifying relevant formulas, and making calculation errors.

Feminine Sound Plurals Endings in /ya:t/ and /yya:t/ in Native and Loan Lexemes in Arabic
Authors: Al-Jarf Reima
Published: January 2024

A sample of 80 loanwords and 100 native Arabic words ending with /ya:t/ or /yya:t/ were analyzed and compared to find out the conditions under which /ya:t/ and /yya:t/ appear in Feminine Sound plural forms of those words.  Results revealed that Arabic speakers pluralize native and loan nouns ending with the glide /y/, which is part of the words, as  ناي/na:y/; &   قبضاي /qabaDa:y/ (Turkish) by directly adding the feminine plural suffix /-a:t/ to the stem without making any other adaptations (نايات /na:ya:t/ flutes & قبضايات /qabadaya:t/ strong-arm).  In native words with a stem ending in the graphemes ى or ي pronounced /a:/ and /i:/, the vowel is shortened and the glide /y/ is added as a liaison consonant as inتمنيات  /tmanniya:t/ wishes; مديات /maday:at/ ranges).  When the loan stem ends in the syllable يا /ya:/, the final long vowel /a:/ is deleted before the plural suffix /-a:t/ as Arabic phonotactics do not allow a sequence of two long vowels as in بكالوريا /bakalo:rya/ > بكالوريات /bakalory+a:t/ high school diplomas. A geminated glide /yy/ appears in the plural of native words as أدبيات /?adabiyy+a:t/ literature; برمجيات /barmadʒiyy+a:t/ software) and plural loanwords as سيديات /si:di:yy+a:t/ CD’s; سيلفيات selfies /selfiyy+a:t/; باربيات /ba:rbi:ya:t/ Barbies; سمفونيات /simfo:ni: +y+a:t/ symphonies. In these examples, there are two explanations of the stem:  One assumes that the masculine singular stem ends in a geminated yy, after which the plural suffix /a:t/ is directly added. The second assumes that the stem is a feminine singular noun/adjective ending in a geminated yy followed by the grapheme ta marbouta ة ــة pronounced /a/. /a/ is deleted when the plural suffix /a:t/ is added, as Arabic does not allow the sequence of two vowels. The vowel preceding the geminate yy is shortened in the plural form of native and loanwords in Arabic. The study gives some recommendations for translation and pedagogy and for future studies on Arabic loanword morphology.
