Wali Nanggroe Institution (LWN) Revitalization and Conflict Resolution Problems in Aceh
Authors: Ridwansyah Muhammad , Noor Firman , Romli Lili , Fadlia Faradila
Published: December 2022

Strengthening the peace in Aceh may be possible by revitalizing the Wali Nanggroe Institution (LWN). Institutional strengthening is necessary to keep Aceh on its peaceful path. However, even LWN's existence has generated debate and differing opinions. This article seeks to answer the following: First, why does LWN deserve to be preserved and why has its revitalization been fraught with difficulties? Second, what is the relationship between the problems LWN faces and the potential role that it plays in conflict resolution? This study employs qualitative research in the form of document studies and in-depth interviews via focus groups with a variety of informants with a focus on specific and privileged institutions. Although LWN has the potential to increase the dignity of the traditional or social side of the people of Aceh, the politicization of institutions, customary discrimination, and the poor implementation of functions has resulted in the emergence of distrust. Because of this low level of mistrust, the institution's potential to serve as a forum for conflict resolution is currently far from being realized.

Salah satu Teori kuantitas David Ricardo mengemukakan bahwa uang yang beredar mempengaruhi kekuatan nilai uang. Apabila jumlah uang menjadi banyak, maka nilai uang akan menjadi lemah dan turun setengah dari awal, begitupun sebaliknya (Emily Nur Saidy 2017). Hampir sama dengan teori sewa tanah David Ricardo bahwa uang sewa dipengaruhi oleh tingkat kesuburan tanah. Semakin subur tanah makin semakin tinggi sewa yang akan dibayar.
Creating frames of reference for chert exploitation during the Late Pleistocene in Southwesternmost Iberia.
Authors: Belmiro Joana , Terradas Xavier , Cascalheira João
Published: December 2022

Southwestern Iberia has played a key role in characterizing Late Pleistocene human ecodynamics. Among other aspects of human behavior, chert procurement and use studies in this region have received increasing attention in the past two decades, especially focusing on the sites showing repeated human occupation, such as the case of Vale Boi (Southern Portugal). However, these studies have been very limited in their geographical scope, and mostly focused on brief macroscopic descriptions of the raw materials. To further our knowledge of the relationship between regional availability of raw materials and its impact on human adaptations and mobility, a more detailed approach to characterizing geological sources is needed. This paper characterizes chert raw materials location, diversity, and availability in a geologically well-defined region of southern Portugal - the Algarve. Through macroscopic and petrographic approaches, we provide a detailed characterization of geological chert sources to build a frame of reference for chert exploitation in the region. Our results show that there are three main chert formations in Algarve, and that despite the within-source variability, sufficient differences at macroscopic and petrographic levels are present to allow clear source attribution. These results provide a baseline for raw material studies in archaeological assemblages across southwestern Iberia, that will be essencial to further characterize the dynamics of human behavior in some of the most important eco-cultural niches.

Published: December 2022

This study aims to determine the effect of partial and simultaneous tax planning and profitability on equity. Tax planning and profitability are used as independent variables—Equity as a dependent variable. The population in this study is all companies in the consumer goods industry listed on the Indonesia Stock Exchange from 2018 to 2021. Sample number 28 consists of 7 companies multiplied by four years of research. A sampling method is purposive sampling. The analysis method used to test hypotheses uses multiple linear regression analysis. The multiple linear regression analysis tests performed on the F test on the third hypothesis obtained an F value of 27,441 and a significance of 0, which means that tax planning and profitability simultaneously affect equity. The result of testing for the first hypothesis showed a t-value of -2.327 and a significance level of 0.028. Based on this result, the conclusion is tax planning partially had a significant adverse effect on equity. The second hypothesis test indicates a t-value of 7.334 and a significance level of 0.00. We can explain that profitability had a significant positive impact on equity.

Authors: Yıldırım Yahya , Yıldırım Duygu
Published: December 2022

The aim of this study is to examine the relationships between anaerobic power, back strength and dynamic balance, which play an important role in wrestler performance. 14 male freestyle elite wrestlers (age = 19.07 ± 0.99 years, height = 1.70 ± 0.04 m, body weight = 74.67 ± 8.48 kg, BMI = 25.57 ± 2.31 kg/m2) voluntarily participated in the study. Anaerobic power, back strength and dynamic balance measurements of the participants were taken. Pearson Correlation test was performed to determine the relationship between these features. A statistically significant positive correlation was found between anaerobic power and back strength, between back strength and right and left leg balance, between left leg balance and right leg balance. As a result, it can be said that back strength is effective on dynamic balance in wrestlers and anaerobic power affects back strength.

Published: December 2022

Background: This study tested the core tenets of how facial scars are perceived by characterizing layperson response to faces with scars. The authors predicted that scars closer to highly viewed structures of the face (i.e., upper lip and lower lid), scars aligned against resting facial tension lines, and scars in the middle of anatomical subunits of the face would be rated less favorably.Methods: Volunteers aged 18 years and older from the United States were recruited through Amazon's Mechanical Turk to complete a face rating survey. Scars were digitally added in different locations and orientations for a total of 14 unique scars added to each face. Each participant rated 50 different faces on confidence, friendliness, and attractiveness. Data were analyzed using linear mixed effects models.Results: A total of 88,850 ratings [82,990 scarred (93.4 percent)] for attractiveness, friendliness, and confidence were analyzed. In univariate linear mixed effects models, the presence of a facial scar did not significantly impact attractiveness (β = 0.016, SE = 0.014, z = 1.089, p = 0.276). A second set of linear mixed effects models identified interactions between location, subunit placement, and orientation to facial tension lines. Scars located on the lower lid mid subunit perpendicular to facial tension lines were rated less attractive (β = -0.065, SE = 0.028, z = -2.293, p = 0.022).Conclusions: On average, a single well-healed facial scar does not negatively affect first impressions of attractiveness, confidence, or friendliness. Specific scar location and orientation combinations, however, such as a perpendicular scar at the mid-lower eyelid, may result in lower perceived attractiveness, confidence, and friendliness.
Mind-wandering as an exploratory response to boredom
Authors: Martarelli Corinna , Baillifard Ambroise
Published: December 2022

In this chapter, the link between mind-wandering and boredom is introduced and defined. Despite the intuitive overlap between the two constructs, there is scarce empirical research that directly tests and theorizes their association. However, mind-wandering as a possible response to boredom, fits perfectly with current functional accounts of boredom. According to such accounts, boredom is conceptualized as a signal that a task at hand is not worth the effort. When no behavioral alternatives are available, an option that is always accessible is to let the mind wander. We suggest that mind-wandering is an exploratory response to boredom especially when a change in activity is not possible or not desired. We take into account different forms of mind-wandering as possible response to boredom, focusing in particular on spontaneous and deliberate mind-wandering. We then propose that the experience of boredom during mind-wandering can be explained by the intended level of control, rather than by the perception of control per se. Finally, we hope that the ideas presented here will inspire future research on the various possible ways in which boredom and mind-wandering might be related.

Published: December 2022

Abstract: Hippocampal circuitry and related cortical connections are altered in first episode psychosis (FEP) and are associated with verbal memory deficits, as well as positive and negative symptoms. There are robust sex differences in the clinical presentation of psychosis, including poorer verbal memory in male patients. Consideration of sex differences in hippocampal-cortical circuitry and their associations with different behavioral dimensions may be useful for understanding the underlying pathophysiology of verbal memory deficits and related symptomatology in psychosis. Here, we use a data-driven approach to simultaneously capture the complex links between sex, verbal memory, symptoms, and cortical-hippocampal brain metrics in FEP. Structural magnetic resonance imaging and behavioral data were acquired from 100 FEP patients (75 males, 25 females) and 87 controls (55 males, 32 females). Multivariate brain-behavior associations were examined in FEP using partial least squares to map sociodemographic, verbal memory, and clinical data onto brain morphometry. The analysis identified two sex-dependent patterns of verbal memory, symptoms, and brain structure. In male patients, verbal memory deficits and core psychotic symptoms were associated with both increased and decreased frontal and temporal cortical thickness and reductions in CA2/3 hippocampal subfield and fornix volumes. In female patients, fewer negative/depressive symptoms were associated with a more attenuated cortical thickness pattern and more diffuse reductions in hippocampal white matter regions. Taken together, the results contribute towards better understanding the underlying pathophysiology of psychosis by highlighting the unique contribution of specific hippocampal subfields and surrounding white matter and their connections with broader cortical networks in a sex-dependent manner.
Evaluation of Rice Genotypes Resistance to Yellow Stem Borer, Scirpophaga incertulas (Walker) through Sex Pheromone Trap
Authors: Nyaupane Sushil
Published: December 2022

Yellow stem borer, Scirpophaga incertulas (Walker) is monophagous insect pest causing serious damage to rice growers of plain regions of Nepal. This study was done to evaluate the host preference of yellow stem borer to the various genotypes of rice. The research design employed was Randomized Complete Block Design (RCBD) with seven treatments and three replications and done in kharif season of 2021. Rice varieties selected were Sabitri, Sarju 52, US 312, Radha 4, Sawa Mansuli, Silki and Hardinath 3, which are popularly cultivated in Kailali. Sex pheromone trap (scirpolure) was installed to monitor the preference of yellow stem borer for various rice varieties, especially at the panicle initiation stage of rice. Statistical analysis of four weeks data of adult male moths trapped on different cultivars of rice revealed that the yellow stem borer adult moths were highly attracted to the US 312 and less attracted to Sarju 52 and Silki varieties. This research implied that the adoption of popular rice variety Sarju 52 could safeguard the farmers from the notorious pest i.e. yellow stem borer of rice.

This study assessed the forest structure and regeneration at the edge and core parts of two community forests, Ram Janaki and Furkesalli of Surkhet district, Western Nepal, and the forest resources use pattern. Different blocks designated by community forest user groups were considered to designate edge and core strata for stratified random sampling. For vegetation analysis and regeneration of tree 15 circular plots (n = 60) of 10m radii; for shrubs 5m radius subplot and for herbs three 1 m radii subplots within the 10 m radii circular plots were considered. Semi-structured questionnaire approach was employed for the collection of ethnobotanical data. Based on importance value index dominant herbs were Ageratum haustoniaum in edge and Heteropogon contortus core part; dominant shrub were Phoenix acaulis in both community forests (RCF and FCF); and Shorea robusta was dominant tree at edge forest of both RCF and FCF whereas Lagerstroemia parviflora was dominant at FCF coreforest. The species diversity was recorded higher in core parts in both forests. The forests are rich in the diversity of medicinal plants with 26 species under 25 genera and 23 families of which root parts were mostly used as ethnomedicine and mostly for gastrointestinal disorder. Besides medicines, firewood, fodder, fruits, vegetable, timber and bedding material were the other uses of forest resources.

Published: December 2022

Green synthesis of silver nanoparticles is of great importance in the field of nanoscience and nanotechnology. Various phytochemical constituents present in whole or parts of plants can act as reducing, capping and stabilizing agents in the synthesis of silver nanoparticle (AgNPs) by green method. In this work, AgNPs have been successfully synthesized in the laboratory by chemical reduction and green method. NaBH4 was used as a reducing agent in chemical reduction method whereas Zingiber officinale leaf extract was used as reducing and capping agent in green method. The properties of as synthesized AgNPs by both green and chemical methods have been examined by UV-Vis spectroscopy, XRD and FTIR method. Besides these, biological activities of as synthesized AgNPs were tested against Bacillus subtilis and Escherichia coli which exhibited remarkable antimicrobial activities in green method. Based on the result, it is found that AgNPs synthesized from ginger plant (Zingiber officinale) leaf extract exhibited significant antimicrobial effect than that by chemically synthesized AgNPs.

In present scenario, nephrolithiasis (renal stones) are more prevalent and highly related with morbidity worldwide. The aim of the study is to associate different biochemical and hemodynamic parameters of renal stones and to see post-operative outcomes. Hundred patients from January 2019 to January 2021 having renal stone in ultrasonography at Shahid Dharmbhakta National Transplant Centre Bhaktapur are included in the study. All variables are measured following the standard protocol. Nephrolithiasis was found to be frequent in male population (60%) who has a habit of regular alcohol intake (65%, p=0.009) and mixed dietary habit (mostly non-vegetarians) (92%, p= 0.042). Calcium oxalate either solely (21%) or mixed type (41%) were higher in proportion. The most common dyslipidemia in recurrent cases were hypercholesterolemia and increased LDL (p<0.001). The significant increase in serum urea (p=0.006) and creatinine (p=0.004) signify decrease in eGFR (p=0.007). Serum creatinine with IQR (1-2.5 mg/dl) was noticed significantly higher in others stone group V in contrast to mixed calcium containing stones group IV. Hydronephrosis was seen in 96% of patient, 7% developed post-operative complication comprising 57% haematuria, 28.5% wound infection and 14.5 % chest infection. Biochemical and hemodynamic parameters should be incorporated in nephrolithiasis to rule out risk of dyslipidemia, chronic kidney disorder and stratify the risk group based on stone composition.

Ultrasound (USG) guided supraclavicular brachial plexus block (BPB) helps in precise delivery of local anesthetic injection, reduced volume or dose of drug providing excellent surgical anesthesia with fewer complications. Objective of the study was to compare effect of two different volumes of Ropivacaine and Lignocaine at two different sites of USG-guided supraclavicular BPB on diaphragmatic motility, quality of block and tourniquet pain. A prospective randomized double-blinded comparative study was conducted among adult patient with below elbow elective surgery. In group A patients (n=17), 20ml of anesthetic solution was injected in the corner pocket and 10ml in the nerve cluster guided with USG. In group B patients (n=17), 15ml of the anesthetic solution was injected in the corner pocket and 5ml in the nerve cluster guided with USG. Hemodynamic parameters, diaphragmatic excursion, onset of anesthetic effects were measured at frequent intervals. The data were analyzed using Statistical Package for Social Sciences at P-value less than 0.05. Hemodynamic profile of the patients were similar in both groups (P-value>0.05). Statistically significant hemi-diaphragmatic dysfunction (partial and complete paralysis) after 15 and 30minutes of blockade was more common in group A than Group B (P<0.05). At 30 minutes after the injection of the anesthesia, all patient in both the groups had complete sensory and motor block in all nerve territory. Tourniquet time was lower in group A (80.35±9.59 minutes vs 84.12±7.75 minutes); however, it was statistically not significant (P-value>0.05). The present study showed that the patients who received lesser half of the required volume of local anesthetics had less incidence of hemidiaphragmatic dysfunction with similar successful rate of blockage (100%) and similar quality of the block as compared to the patients who received greater half of the required volume of local anesthetics.
Up-to-date Immunization Coverage among Infants Attending a Clinic at a Tertiary Hospital During the Second Wave of COVID-19 Pandemic in Kathmandu, Nepal
Authors: Silvanus Vinutha , Shrestha Monika
Published: December 2022

This study aimed to evaluate the utilization and quality of routine immunization (RI) services at a tertiary hospital during the second wave of the COVID-19 pandemic period. An observational analytical study was carried out in the Immunization Clinic of a tertiary hospital in Kathmandu, Nepal. The infant cohort was enrolled over a period of 4 months and followed up for a year (April 2021 to August 2022). Up-to-date immunization (UTD) status, overall and vaccine specific drop-out rates were quantified and reasons for missed or delayed doses were elicited from caregivers. An infant who received BCG, 3 doses of Pentavalent (DPT-HEPB-HIB) and OPV containing vaccine, one dose of fractional IPV, 2 doses of Rotavirus vaccine, 3 doses of PCV and first dose of Measles-Rubella (MR1) vaccine prior to their first birthday was categorized as UTD. Dropout rates between early and later vaccine doses were defined as the percentage of children that started their immunization series, but did not complete it for some reason. Among 227 infants (44.1% female) enrolled in the study, about three-fourths (74.5%, 95% CL 68.3% to 80.0%) were identified as UTD. Among UTD infants (n=169), two-thirds of the infants (65.1%, 95% CL 57.4% to 72.3%) had received the vaccines at the recommended age milestones. Overall dropout rate (BCG-MR1) was about 19% with highest dropout between the first and third Pentavalent dose (10%). Maximum delay was seen for MR1 vaccine. Common reasons for missed or delayed visits were that the infant received vaccine at another health facility, or the infant was ill, caregivers had travelled to village/maternal home or were busy. In conclusion, three-fourths of the infant cohort had received all of the recommended vaccines as per the National immunization schedule at our immunization clinic. However, one third had delayed their visits to the clinic. While routine immunization reporting looks at the number of vaccine doses that have been administered at an immunization clinic, this study has documented a sustained utilization of RI services during the second wave of the pandemic period. The lower dropout rate for pentavalent vaccine indicates a qualitative improvement in RI services at the tertiary hospital. However, an ongoing scrutiny of immunization data recording with a progression to digital health records and provision of timely reminders to caregivers may further help to strengthen RI services at the institutional level.

Published: December 2022

One option for a digital signature solution for devices with low memory and low bandwidth transmission over channels uses a short digital signature scheme based on Weil bilinear pairing aimed at short processing times, fast computation, and convenient deployment on applications. The computational technique of non-degenerate bilinear pairings uses supersingular elliptic curves over a finite field Fpl (where p is a sufficiently large prime number) and has the advantage of being able to avoid Weil-descent, Menezes-Okamoto-Vanstone (MOV) attacks, and attacks by the Number Field Sieve algorithm. Compared to Elliptic Curve Digital Signature Algorithm (ECDSA) digital signature schemes, generating a digital signature for a Boneh-Lynn-Shacham (BLS) scheme using Weil bilinear pairing on a supersingular elliptic curve is simple. In this study, the authors replace non-degenerate bilinear pairing calculations on a supersingular elliptic curve with a Weil pairing with PεE(Fp ), QεE(Fp1) and a higher security multiplier α=12 in the BLS short digital signature scheme. The execution time of the BLS short digital signature program showed improvement compared to the commercial ECDSA digital signature scheme.

Indirect carotid cavernous fistulas (ICCFs) are rare disease entities triggered by indirect low flow between the cavernous sinus and the meningeal branches of the internal or external carotid artery or from both. To evaluate clinical characteristics, angiography, and relationship to the result of endovascular treatment of indirect carotid cavernous fistulas. A prospective study of 32 patients diagnosed to identify ICCFs through digital subtraction angiography (DSA) and intravascular intervention. Results showed that indirect carotid cavernous fistulas were more common in females of advanced age (68.8%) and occurred spontaneously (87.5%); the most common symptoms included chemosis (93.75%), headache (87.5%), proptosis (53.1%), and tinnitus (37.5%) with type D being the most common (81.2%). Thirty out of thirty-two patients with intervention had complete flow block (83.3%), near complete (13.3%), and failure in one case. Incomplete occlusion interventions and failures were of the type D complication. The complication and number of drainage veins are related (p<0.05). ICCFs have diverse symptoms that depend on the drainage veins but most commonly were red eyes, headache, and protruding eyes. The ICCFs were mostly D-type formation and endovascular treatments were safe and effective. Common complications occurred in the case of many veins draining.

Published: December 2022

A nivel internacional la implementación de sistemas de control de la concentración de nitrato (NO3 ) en alimentos para humanos, obliga a contar con métodos de determinación que además de precisos, sean prácticos y económicos. En este trabajo se compararon dos métodos para la determinación de la concentración de nitratosen extractos de hojas secas de lechuga, el potenciométrico basado en el uso del electrodo de actividad específica, y el colorimétrico propuesto por Cataldo et al. (1975). Los valores obtenidos por colorimetría fueron 30% mayores a los obtenidos por potenciometría, diferencia originada por la interferencia que genera el color de los extractos. Cataldo et al. (1975) habían propuesto descontar la absorbancia del color del extracto a cada muestra para eliminar esa interferencia, pero solamente cuando los extractos eran obtenidos a partir de tejido fresco. Cuando utilizamos este procedimiento en extractos de tejido seco, la diferencia en la concentración de nitratos determinada por ambos métodos no fue estadísticamente significativa. El otro procedimiento evaluado para eliminar el color del extracto fue el agregado de carbón activado, que produjo resultados similares a los obtenidos con la cuantificación del blanco. El uso de carbón activado, sin embargo, resultó más simple, ya que no requiere utilizar un blanco para cada muestra.

Published: December 2022

Los oligoquetos terrestres son importantes componentes de los agroecosistemas. Tienen efectos en la dinámica de la materia orgánica y los ciclos de nutrientes, en la estructura del suelo y en la diversidad y actividad de los niveles tróficos subordinados. El clima, el tipo de suelo, la topografía, la vegetación y las prácticas de manejo, determinan la composición de las comunidades. El objetivo de este trabajo fue evaluar el efecto de distintas intensidades de uso del suelo sobre los oligoquetos. En un experimento de larga duración con siembra directa y pastoreo en INIA Treinta y Tres – Unidad Experimental Palo a Pique se realizaron muestreos durante el año 2007. Los tratamientos considerados fueron: cultivo continuo (CC), rotación corta (RC), rotación larga (RL) y pradera permanente (PP). Predominaron tres especies, Aporrectodea caliginosa (Lumbricidae) y Eukerria stagnalis y Eukerria sp. (Ocnerodrilidae). El uso del suelo tuvo un efecto significativo sobre la composición de las comunidades. La mayor y menor densidad de Ocnerodrilidae se registró respectivamente en CC y PP. Aporrectodea caliginosa fue más y menos abundante en PP y CC. Los valores más altos y bajos de densidad de capullos y de la relación adultos/inmaduros correspondieron, respectivamente a PP y CC. Para todas las variables consideradas en RL y RC, se registraron valores intermedios. La composición específica de las comunidades de oligoquetos, así como la relación adultos/ inmaduros y el número de capullos reflejaron el impacto que producen distintas intensidades de uso del suelo en siembra directa con pastoreo sobre el contenido de carbono orgánico y la densidad aparente del suelo.

Se realizaron ensayos a campo en 2007 y 2008 en los que se evaluaron en total 40 materiales genéticos. La incidencia de P. destructor se evaluó semanalmente, se ajustó una ecuación logística a los datos y se calculó el Área debajo de la Curva de Progreso de la Enfermedad (AUDPC). En 2007, el germoplasma local mostró diversidad en la incidencia de la enfermedad (3 a 99%), en la severidad (7 a 40% del área foliar afectada) y en el AUDPC. En 2008, los materiales evaluados también mostraron diferencias, aunque de menor magnitud. Se encontró relación entre el ciclo fenológico y la resistencia. El grupo de accesiones de día largo presentó mayor resistencia que los grupos de día intermedio y de día corto. Esto podría ser el resultado de factores de resistencia específicos presentes en el germoplasma de día largo, o de diferencias fisiológicas relacionadas al estado de desarrollo que condicionan la susceptibilidad al patógeno. En 2008, la evolución de la enfermedad fue muy variable. La incidencia de P. destructor cayó bruscamente en una evaluación, y subió a la semana siguiente hasta 100% de las plantas para varias accesiones. La diversidad observada en la respuesta a P. destructor confirma el potencial del germoplasma local para ser usado como fuente de resistencia en el mejoramiento de cebolla.

One of the most common metabolic illnesses in the world is diabetes mellitus. This metabolic disease is responsible for a large percentage of the burden of kidney damage and dysfunction. The goal of this study was to look into the renal function of diabetic patients using metformin monotherapy who came to Mosul's Al-Wafaa diabetes care and research facility. During the period 1 January 2021 to 30 April 2021, 47 patients with T2DM (age 50.48 7.74 years) were enrolled in this case-control study. These patients' results were compared to a control group of 47 seemingly healthy people (age 45.89 9.06 years). All participants' demographic and medical histories were acquired through the delivery of a questionnaire. Blood samples were collected and tested for the mt-ND1 gene, HbA1c, uric acid, urea, and creatinine, among other things. In diabetics, there were extremely significant increases in HbA1c, Urea, and Creatinine (p < 0.001, 0.003, and 0.043, respectively) when compared to the control group. In diabetic patients, however, uric acid levels did not change significantly. HbA1c and uric acid had a strong negative connection (r = -0.045 and 0.05, respectively). In diabetic individuals, the number of mitochondrial copies was substantially lower than in the control group (p < 0.001). In comparison to non-diabetic controls, diabetic patients treated with mono-metformin treatment had a lower mitochondrial copy number and moderate renal impairment.

A simple and highly sensitive cloud point extraction process was suggested for preconcentration of micrograms amount of isoxsuprine hydrochloride (ISX) in pure and pharmaceutical samples. After diazotization coupling of ISX with diazotized sulfadimidine in alkaline medium, the azo-dye product quantitatively extracted into the Triton X-114 rich phase, dissolved in ethanol and determined spectrophotometrically at 490 nm. The suggested reaction was studied with and without extraction and simple comparison between the batch and CPE methods was achieved. Analytical variables including concentrations of reagent, Triton X-114 and base, incubated temperature, and time were carefully studied. Under the selected optimum conditions, the linearity ranges of calibration curves were 1-9 and 0.5-8 µg/mL with detection limits of 0.26 and 0.09 µg/mL of ISX for batch and CPE methods respectively. A relative standard deviation (RSD %) best than 1.98 and 2.67 % with the percentage recoveries range 100.14 and 99.63 % were obtained for both methods respectively. The proposed methods were successfully used in routine analysis of ISX in pharmaceutical forms with high accuracy and reproducibility.

Barley production in the Rostov region, as well as throughout Russia, has taken its niche in agricultural production. Winter barley attracts farmers’ attention with its unpretentiousness and high productivity. The relevance of immunology used in the production of barley varieties does not decrease over time. Yield losses due to various leaf diseases can be as high as 30–50 %. The most common pathogens in the region are powdery mildew and helminthosporium blotches. The most effective and efficient way to improve the resistance of new varieties is the use of artificial infectious backgrounds. Provocative and extreme conditions promote a selection of parental forms and breeding lines that are most resistant to pathogens. The current paper has presented the results of the estimation of winter barley breeding and collection material based on the FSBSI Agricultural Research Center «Donskoy». The purpose of the study was to identify winter barley varieties and lines which are stably resistant and tolerant to leaf-stem pathogens common in the Rostov region. About 250 samples are being estimated in the period from 2019 to 2021. Over the years of study, there have been identified such varieties and lines resistant to powdery mildew as ‘Bezosty 1954’ (RF), ‘Grand’ (RF), ‘Parallelum 1967’, etc. Resistance to heliminthosporium spotting was demonstrated by the varieties ‘Bezosty 1954’ (RF), ‘Grand’ (RF), ‘Rostovsky 908’ (RF), ‘Donskoy 11’ (RF) and the lines ‘Parallelum 1967’, ‘Parallelum 1974’, ‘Pallidum 1916’, ‘Pallidum 1970’, ‘Parallelum 1960’, ‘Parallelum 1911’, ‘Nutans 1895’ and others. There were also identified such varieties with resistance or tolerance to both pathogens as ‘Grand’ (RF), ‘Sekret’ (RF), ‘Fox 1’ (RF), ‘Marusya’ (RF), ‘Karisma’ (England) and the lines ‘Bezosty 1954’, ‘Parallelum 1967’, ‘Parallelum 1974’, ‘Parallelum 2015’, ‘Parallelum 2016’, ‘Parallelum 2017’. All presented varieties and lines are proposed for use in further breeding for immunity to the studied pathogens.

Anther culture is the most effective and not technically complex tool for obtaining double wheat haploids. The current study is devoted to the research of the influence of the genotype and concentration of the growth regulator 2.4-D on the efficiency of androgenesis in vitro of spring bread wheat. The purpose of the study was to estimate the efficiency of the anther culture of hybrids of the first and second generation and their parental varieties and to study its dependence on different concentrations of the growth regulator 2.4-D. There has been carried out the estimation of the traits of the F1hybrids, the F2population, and the parental varieties ‘Obskaya 2’ and ‘Novosibirskaya 15’ when 2.4-D was added to the induction medium at a concentration of 1 and 2 mg/l. There has been established that the F2population and the parental variety ‘Novosibirskaya 15’ are characterized by the largest indicators. The average values were significantly surpassed by the F2population in the traits ‘number of productive anthers per 100 anthers’ and ‘number of all regenerants per 100 anthers’ at 1 mg/l of 2.4-D. The variety ‘Novosibirskaya 15’ surpassed the average values in traits ‘number of sprouts per 100 anthers’ and ‘number of all regenerants per 100 sprouts’ at 2 mg /l of 2.4-D. The trial has shown that the best responsiveness of the anther culture for the studied genotypes was when the growth regulator 2.4-D was added to the induction medium at a concentration of 1 mg/l. The variety ‘Novosibirskaya 15’ has been characterized by good responsiveness in anther culturein vitroand could be used as a donor of valuable alleles in wheat breeding programs using DH technologies.

The purpose of the study was to identify the effect of the length of a vegetation period of collection samples on protein percentage in pea seed. The study was carried out in the southern part of the Rostov region on the fields of the FSBSI «ARC «Donskoy» in 2017–2020. The objects of the study were 100 collection pea samples from the N. I. Vavilov ARIPGR (VIR), including 53 leafless samples and 47 leafy ones. The longest vegetation period on average for the collection (93.8 days) was identified in 2017. The intervarietal variability of this trait, expressed by a variation coefficient, this year was 5.5 % with a minimum value of 63 days and a maximum of 101 days. In the group of varieties of the leafless type, the intervarietal variability was 6.4 % (min. 63 days; max. 100 days), in the leafy group it was 4.2 % (min. 80 days; max. 101 days). In other years, there was a reduction of a vegetation period and a decrease in its intervarietal variability due to unfavorable weather conditions in the form of a lack and shortage of precipitation against the background of elevated and high air temperatures. But they also led to the maximum accumulation of protein in seeds of collection samples, thereby showing the greatest intervarietal variability of this indicator. The calculation of the correlation coefficient showed the absence of a correlation dependence of protein percentage on length of vegetation, both on average for the collection (r = 0.03+0.10) and for the groups of leafless (r = 0.08+0.14) and foliate (r = 0.05+0.15) leaf morphotypes. The construction of graphs with errors for groups of leafy morphotypes revealed samples with a protein percentage of more than 25.0 %. In the group of the leafless morphotype, they had a vegetation period of 78–80 and 83–85 days, and in the group of the leafy morphotype, it was 77–79 days on average over the years of study.
