Published: January 2021

Phytotoxicity of soil aluminum (Al), both directly to the plant growth as well as indirectly through the increase of soil potential acidity, is closely related to the occurrence of various soil soluble-Al species. Amongst them, Al3+ and monomeric-Al species are the primary causes of Al phytotoxicity in soils with high Al content. This study was aimed to evaluate the effects of soil amelioration with dolomite and base-activated lignite (BAL) on changes in soluble-Al species and other soil chemical properties, and vegetative growth of soybean (Glycine max Merr) on Ultisol of Jasinga (Al-dd 16,03 cmol(+)/kg). A green house experiment was conducted by applying a Completely Randomized Design with dolomite and BAL amelioration as the treatments, each with three levels of repectively 0, 1, 1,5 x exchangeable-Al and 0, 2,5, 5 tons BAL ha-1, and three replications. The ameliorants were incubated at field capacity of soil moisture content for one week before planting soybean for one month. Soil soluble-Al speciation was carried out using colorimetric aluminon method to determine concentrations of total soluble-Al, monomeric-Al, and polymeric-Al species. Monomeric-Al were further speciated into inorganic monomeric-Al and organic monomeric-Al species. The results revealed that only dolomite amelioration that significantly increased soil pH-H2O, pH-KCl, Ca- dd, Na-dd, and decreased exchangeable-Al concentration, except for those of all soluble-Al species that only showed a decreasing trend. Soil exchangeable-Al that was negatively and significantly correlated with soybean measure parameters were plant height, root length, total roots and shoots wet and dry weights, as well as Ca concentration. These results indicated that soil Al phytotoxicity evaluation could be relied on the result of routine analysis on soil exchangeable-Al concentration.

Growth Performance and Profitability of Broilers Chickens with Vermi meal Supplementation under Total Confinement Management
Authors: Bollido Marcos Erram
Published: January 2021

This study was conducted to determine the growth performance and profitability of broilers chicken with vermi meal supplementation under a total confinement management system. A total of 60 broiler chickens were randomly distributed to four dietary treatments: T1= commercial feed (CF), T2= CF+2% vermi meal (VM), T3= CF+3% VM, T4= CF+5% VM inclusion in a completely randomized design. Feed conversion ratio was not significantly influenced by VM supplementation. However, the highest feed intake was recorded in broilers fed CF supplemented with 2% VM (T2) while control broilers fed only CF (T1) had the lowest feed consumption. Broiler chickens fed CF supplemented with 2% VM (T2) were recorded with the highest values of final body weight and weight gain compared to T1 group and T4 group, respectively. However, broiler in T2 group had similar values of body weights and weight gains compared to T3. Consequently, 2% level of VM had an optimum result in final weight, weight gain, and feed consumption, while comparable to the other treatments in water consumption, feed conversion ratio, dressing percentage, and carcass weight. Cost and return analysis of the dietary treatments with VM showed a negative effect, since the higher concentration of VM supplementation had the higher cost in production, due to the expensive price of imported vermin or earthworm meal.

Lake Matano is an ancient lake that has a high endemicity. Opudi fish (Telmatherina prognatha) is an endemic fish that is vulnerable to extinction and needs to be preserved. The threat of invasive species and habitat degradation can cause a decrease in opudi fish populations. This study aimed to examine the growth parameters associated with growth coefficients and mortality in Lake Matano so that population can be sustainable. The study was conducted at Lake Matano from March 2018 to February 2019. Samples of fish were caught using a net bag measuring 30 m long, 2 m wide with a mesh size of 0.5 inches. Analysis of fish growth was based on total length-frequency data. These data were analyzed using the FISAT II software. The sizes of male and female opudi fish obtained ranged from 30-70 mm. Growth patterns of von Bertalanffy butina in male fish are male Lt = 76.50 [1-e-0.46 (t + 0.47)] and female fish Lt = 74.05 [1-e-0.51 (t + 0.52)]. The total mortality value of male fish was higher (Z = 1.65) compared to female fish (Z = 1.50), the natural mortality value of male opudi fish was lower (M = 0.84) compared to that of female fish (M = 0.91).

Published: January 2021

Rice is a staple food for most Indonesian population. Nowadays, people want staple foods that are not only filling but also do not increase blood sugar concentration (low glycemic index). One of foods that contain higher starch, lower glycemic index, and higher fiber than rice is white corn. The white color of the corn is an advantage because if it is made in grits it can resemble rice. Weakness of white corn is harder than rice. To soften and make it easier to consume, it is coated with an edible packaging made from tapioca. The purposes of this study were to study (1) the quality of dried corn rice from local white corn Anoman 1 variety in edible packaging with packaging thickness of 0.7, 0.9, 1.1, 1.3, and 1.5 mm; (2) the quality of cooked white corn rice produced. The results showed that the thickness of the edible packaging significantly affected (1) the moisture, ash, protein, fat, and carbohydrate contents of dried white corn rice and (2) all parameters of cooked white corn rice (a = 0.05). The best cooked corn rice based on the stickiness test was found in coated dried corn rice with edible packaging with a thickness of 1.5 mm. Characteristics of (1) dried white corn rice contained 11.39% water, 0.21% db ash, 15.23% db protein, 0.53% db fat, 72.64% carbohydrates, 2.11% crude fiber, (2) the quality of cooked of white corn rice were 18.17 g / mm2 stickiness, yellowish color (score 1.1), slightly distinctive aroma of corn (score 2.5), slightly fluffier texture (score 3.4), and rather strong sweet taste (score 2.8).

Published: January 2021

Background: The aimed of this study was to identify and ranking noise control solutions by using fuzzy Delphi approach and FAHP-fuzzy vikor method in an oil refinery.
Methods: This descriptive-analytical study was conducted in the catalytic conversion unit in an oil refinery. First, noise measurement was performed based on the standard to identify the sources of noise generating factors. Second, the criteria and initial solutions were identified by reviewing the texts and conducting interviews with experts and the most significant criteria and solutions for noise control were selected using the fuzzy Delphi method. Then, the criteria were weighed using the fuzzy analytic hierarchy method.  Finally, the control solutions were prioritized using fuzzy Vikor method.
Results: The results of FAHP method indicated that cost with final weight (0.2796) had the highest weight and non-interference in the process with final weight (0.1107) had the lowest weight among the identified criteria. The ranking of noise control solutions with fuzzy Vickor method indicated that the construction of an acoustic room for workers exposed to weights (Q = 0) as the most appropriate solution for noise control and the method of modifying or changing the work process with the final weight (Q = 1) is the last noise control solution among the solutions identified in the studied refinery.
Conclusion: The use of multi-criteria decision-making methods in selecting the appropriate solution for noise control can overcome the uncertainties in making an appropriate decision for selecting the best solution for noise control. In this study, a decision model was introduced for selecting the most appropriate noise control solution based on different criteria and this model can be used in other industries which should select a noise control solution.

Published: January 2021

Background: Styrene is one of the chemicals used in industries, especially the petrochemical industry, which affects health. Singaporean methods and the WHO use different parameters to assess the carcinogenic risk of the substance. Therefore, this study aimed to compare the level of carcinogenic risk due to exposure to styrene using the Singapore Department of Occupational Health with the risk levels provided using the WHO to achieve high-reliability results.
Methods: In this study, 150 air samples were collected from the respiratory area of 50 employees by NIOSH1501 method, after identification of styrene emission units and preparation of identical exposure groups. The samples were analyzed by Varian-cp3800 gas chromatograph. Finally, the risk of styrene's health effects on petrochemical staff was calculated using the method of the Singapore Department of Occupational Health, and the results were compared with the risk levels of styrene presented by WHO.
Results: The carcinogenicity of styrene was higher in polybutadiene latex (PBL) (2.3 ) and the fire department (1.3 ) in comparison with the other units. The World Health Organization-defined risk levels predicted 22% of staff to be a "definitive" carcinogenic risk. While the Singapore Department of Occupational Health approached a "low" risk rating.
Conclusion: A "low" risk rating was obtained through the Singapore Department of Occupational Health. But the WHO method for 30 years of exposure to styrene predicted "probable risk" and "definitive risk." This showed a high difference in the results of the two semi-quantitative methods used.

Published: January 2021

Background: The study of the production and emission of greenhouse gases, including CO2 in the atmosphere, is one of the most important environmental issues and concerns of the international community. This study was conducted to investigate the effect of temperature and furnace fuel concentration changes on CO2 and CO production.
Methods: In this study, using HSC Chemistry 6 software, the existing reactions for fuels used in the furnace, including CaCO3, MgCO3, Fe2O3, and Fe3O4, were simulated. The concentrations of carbon dioxide and carbon monoxide produced at different temperatures were investigated.
Results: In the CaCO3 reaction, the temperature has a direct effect on carbon dioxide production but no effect on carbon monoxide production. In the MgCO3 reaction, the temperature has little effect on the production of both, and for the rest of the reactions, the effect of temperature depends on the molar composition and reaction conditions.
Conclusion: In general, the results show that temperature affects the production of carbon dioxide and monoxide, so the emission of these gases to the environment can be reduced by adjusting the temperature of the furnace reactors.

Authors: Amine Khadija , Radaj Youssef , Gharibi Amina , Kissa Jamila
Published: January 2021

Objectives: The aim of this systematic review was to assess the clinical efficacy of bone regeneration for treatment of peri-implantitis.
Materials and Methods: Electronic search of the literature was performed to identify randomized clinical trials (RCTs) and case series on treatment of peri-implantitis using bone regeneration procedures with at least 6 months of follow-up. The guidelines of the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) were applied. The risk of bias was assessed using the Cochrane Collaboration’s Risk of Bias tool.
Results: Two RCTs and 16 case series with a total of 520 treated patients (2002 implants) were included. Bone regenerative procedures showed controversial results regarding bone fill. Two studies reported statistically significant bone gain while four studies reported insignificant bone gain. Other studies reported bone gain with no P value. Pocket depth (PD) reduction varied among the studies since four studies reported a significant reduction in PD while four others reported insignificant reduction in PD. Other studies reported a reduction in PD with no P value. Bone regeneration procedures seemed to decrease bleeding on probing (BOP) but they did not seem conducive to increase the width of keratinized gingiva. Increased keratinized gingiva was noted in cases with subepithelial grafts.
Conclusion: Evaluation of the effectiveness of bone regeneration techniques in this systematic review presented limitations related to heterogeneity in patient selection (age, history of periodontitis, smoking status and implant system), means of disinfection and decontamination, and variability of the materials used for treatment.

Authors: Ahmadi Ebrahim , Khajehali Jahangir
Published: January 2021

Background: Insecticide resistance is one of the most important problems associated with the control of Musca domestica, due to the potential of the rapid development of resistance to different chemical insecticides. The present study was carried out to evaluate dichlorvos resistance in the house fly populations collected from central regions of Iran, Isfahan Province and Chaharmahal and Bakhtiari Province, during 2017 to 2019.
Methods: Bioassays were carried out using a standard topical application method as well as a fumigation method. The Koohrang population (susceptible) with the lowest LD50 values to dichlorvos was chosen to calculate the resistance ratios (RR). Altered sensitivity of acetylcholinesterase (AChE), a target enzyme for dichlorvos, was investigated.
Results: According to the results, very high levels of dichlorvos resistance were observed in the Mobarake population (RR= 80.25-fold by topical application and 33-fold by fumigation bioassay), and Isfahan population (RR= 107.30-fold by topical application and 43-fold by fumigation bioassay) compared to the Koohrang population. Acetylcholinesterase of the Koohrang population was the most sensitive to inhibition by dichlorvos based on the determination of median inhibitory concentration (IC50), but AChE of Mobarake and Isfahan populations were 741.93- and 343.94- fold less sensitive to inhibition.
Conclusion: The insensitivity of AChE was possibly involved in dichlorvos resistance in the house fly populations.

Published: January 2021

Background: Asymptomatic malaria, which usually exists in low parasitemia, acts as the Plasmodium species reservoirs contributing towards malaria transmission. This situation hinders malaria elimination programs in endemic areas, thus necessitating an active case detection with a high sensitive method and treatment of cases. This is why we used a High Resolution Melting (HRM) assay to monitor the trend of asymptomatic malaria in a malaria endemic area of Iran which is under elimination program.
Methods: The peripheral blood was sampled from 271 clinically approved non-febrile individuals from a malaria endemic zone of southeastern Iran for asymptomatic malaria prevalence detection by microscopy, Rapid Diagnostic Tests (RDTs) and HRM methods. The HRM assay was done based on the amplification of 18S SSU rRNA gene.
Results: The HRM assay revealed infections from three individuals out of 271 (1.1% asymptomatic malaria prevalence) from the participants, two Iranian natives with Plasmodium vivax infection and one Pakistani immigrant with P. falciparum infection. Neither microscopy nor RDTs detected Plasmodium spp infections from the 271 non-febrile individuals. The nucleotide sequencing analysis of the positive controls used in this study showed a close homology with the reference gene bank sequences of P. falciparum 3D7 (CPO16995.1) and P. vivax Sal-1(UO3079.1).
Conclusion: This study revealed a low frequency of asymptomatic malaria trend within malaria endemic areas of southeastern Iran which are under intense elimination program and also the ability of HRM assay in detecting low Plasmodium spp parasitemia beyond the limits of microscopy and RDTs.

Authors: Sayono Sayono , Anwar Risyandi , Sumanto Didik
Published: January 2021

Background: Derris elliptica extracts have a high larvicidal potential against the laboratory strain of Aedes aegypti larvae, but the effect on offspring larvae of pyrethroid-resistant strains of the species is lack understood. This study aimed to determine the larvicidal activity of the ethyl acetate extract of tuba root against the third-instar larvae of the Cypermethrin-resistant Ae. aegypti offspring.
Methods: The experimental study occupied four levels of ethyl acetate extract of D. elliptica namely 10, 25, 50, and 100 ppm, and each level was four times replicated. As many as twenty of healthy third-instar larvae, offspring of Cypermethrin-resistant Ae. aegypti were subjected to each experiment group. Larval mortality rate and lethal concentration 50% subject (LC50) were calculated after 24 and 48 hours of exposure time.
Results: Mortality of larvae increased directly proportional to the increase of extract concentration. Larval mortality rates after 24 and 48 hours of exposure were 40–67.5% and 62.5–97.5%, and LC50 were 34.945 and 6.461ppm, respectively.
Conclusion: The ethyl acetate extract of D. elliptica has the high effectiveness larvicidal potential against the thirdinstar larvae, offspring of the Cypermethrin-resistant Ae. aegypti. Isolation of the specific compound is necessarily done to obtain the active ingredient for larvicide formulation.

Published: January 2021

Background: The aims of this study were to evaluate the efficiency of two capture methods for providing live sandflies used for determining the susceptibility level of Phlebotomus papatasi, the main vector of zoonotic cutaneous leishmaniasis in Lorestan Province, west of Iran.
Methods: The sand flies were collected from indoor and outdoor by hand-catch and baited traps during the peak of seasonal activity. The susceptibility level of sand flies was assessed using insecticide-impregnated papers against DDT 4%, bendiocarb 0.1%, permethrin 0.75%, deltamethrin 0.05%, and cyfluthrin 0.15%.
Results: A total of 2486 live sandflies were caught from both indoor and outdoor places. Totally 849 sand flies were caught from outdoors with a sex ratio(SR) 0.1 versus 1637 sand flies collected from indoor using the hand-catch method with SR= 0.6. The dominant species of sand flies was Ph. papatasi in the study area. Mortality rates of outdoor-collected sand flies were exposed to DDT 4%, deltamethrin 0.05%, permethrin 0.75%, and bendiocarb 0.1%, and mortality rate ranged from 92.0–97.9% and for indoor-collected sand flies were 87.7–96.8%. Both outdoor and indoor collected sand flies were susceptible to cyfluthrin 0.15% that caused 100% mortality.
Conclusion: Based on the findings, the most appropriate method for collecting the live female Ph. papatasi is the baited traps due to providing enough females is necessary for conducting the susceptibility tests. The finding indicated that Ph. papatasi wasresistant to DDT, under ‟verification required‟status to deltamethrin, permethrin, bendiocarb, and susceptible to cyfluthrin.

Authors: Talebzadeh Fahimeh , Oshaghi Mohammad Ali , Akbarzadeh Kamran , PanahiMoghadam Somayeh
Published: January 2021

Background: Flesh flies (Diptera: Sarcophagidae) are considered as myiasis agents and important evidences in forensic investigations. However, their use has been restricted because, at all larval stages and female adults, morphological species identification is difficult or very challenging. This study investigated to test utility of mitochondrial cytochrome oxidase subunit I (mt-COI) sequences for differentiation of six forensically important Iranian flesh flies namely, Sarcophaga crassipalpis, S. flagellifera, S. hirtipes, S. aegyptica, S. africa and S. argyrostoma.
Methods: Male specimens were morphologically identified to species level and then the genomic DNA of the flies were extracted and subjected to polymerase chain reaction (PCR) against mt-COI gene. The PCR products were sequenced and the obtained sequences were analyzed for the species specific restriction fragment length polymorphisms (RFLPs).
Results: Rate of genetic variation between species was 6–10% which was enough to find restriction enzymes (RE) that were able to produce species-specific RFLP profiles. Combinations of three REs: BsrFI, RsaI and HinfI, provided diagnostic bands for identification of the six Sarcophaga species.
Conclusions: The results of this study showed that molecular markers such as RFLPs enhancing the use of evidence from flesh flies in forensic investigation. However, lack proper restriction sites in the COI region inhibited introduction of a single restriction enzyme for easy species identification. It is recommended to apply larger part of DNA such as combination of COI and COII genes to provide better RFLP markers for species identification of flesh flies.

Multiple superficial mucoceles on the lower lip of a patient with phenylketonuria: A case report
Authors: Alavi Namvar Mahsa , Rafieyan Sona , Fathi Afkari Behzad
Published: January 2021

This article reports a 13-year-old boy with phenylketonuria and multiple superficial mucoceles on his lower lip. Phenylketonuria (PKU) is a serious and rare genetic disorder that affects the levels of amino acids such as phenylalanine in the body. If left untreated, PKU can negatively affect mental function and cause retardation. Patients with PKU receive less oral examination compared to the normal population. Mucoceles are lesions formed by the accumulation of mucous of salivary glands in soft tissue by blockage or extravasation. Local trauma has been identified as the main cause of mucoceles development. Superficial mucoceles are rare in the lower lip. These patients need close oral and maxillofacial examination to find problems, which may be related to their systemic problem. Micro-marsupialization is a conservative therapeutic approach for management of pediatric oral mucoceles. Management of trauma in patients with mental retardation is an important issue.

Published: January 2021

The purpose of Dentofacial Deformity Treatment is to achieve the proper aesthetic and function- al occlusion results. Conventional orthognathic surgery involves a long-term orthodontic phase before surgery for about 18 months, in which patients’ facial appearance worsens and their mo- tivation decreases. In the SFA (surgery first approach) method, the surgery is performed before orthodontics and orthodontic therapy is performed to improve dental occlusion and final settle- ment. Two main advantages of this method are the reduction of the therapy period and the initial improvement in the patient’s facial appearance. The SFA has certain benefits, especially in Class 3 malocclusion. In this case report, a 19-year-old girl with a relatively severe Class 3 malocclu- sion with skeletal discrepancy due to a mandibular prognathism and maxillary retrognathism, and asymmetrical face with chin deviation to left is presented with a unilateral posterior cross bite which was effectively treated using the SFA protocol. The SFA therapy was performed by removing orthodontics before surgery, followed by maxillary advancement surgery, and posterior maxillary impaction and postoperative orthodontic sets to dental alignment and settling the occlusion. De- spite the overall reduction in the orthodontic therapy period to less than 9 months, good results and functional occlusion were obtained.
Corrosion Inhibitive Potentials Of (E)-5-((4-Benzoylphenyl)Diazenyl)-2-Hydroxybenzoic Acid On Mild Steel Surface In 0.5 M HCl- Experimental And DFT Calculations

Published: January 2021

One of the ways of reducing metal corrosion and its devastating effects is by using organic corrosion inhibitors. This is because of the π-conjugation in their moieties, their ability to donate electrons to the metal’s vacant d-orbitals, and their low lying LUMO orbitals for accepting electrons as well from the metal, all these improve their adsorption on the metal surface. (E)-5-((4-benzoylphenyl)diazenyl)-2-hydroxybenzoic acid (AD4) was synthesized via the coupling reaction of p-aminobenzonephenone and Salicylic acid, characterized via FTIR, UV/Vis, 1H-NMR, and 13C-NMR spectroscopy. The melting point of AD4 is 103oC–106oC indicating that it is thermally stable and pure. Gravimetric and potentiodynamic polarization techniques were employed to obtain the corrosion rates (Cr) and percentage inhibition efficiency (%IE) at different concentrations of the inhibitor and at different temperatures. The thermodynamic parameters like Enthalpy, ∆Hoads, Entropy, ∆Soads and free energy of adsorption (∆Gads) of Adsorption were calculated. The Langmuir adsorption isotherm was used to describe the adsorption of AD4 molecules on mild steel. Quantum mechanical calculations were employed to calculate the electronic properties and global reactivity descriptors of AD4. The theoretical results are broadly consistent with experimental results. From the results obtained AD4 could be used as a corrosion inhibition agent in the oil and gas industries.
Riesgo moral en la Garantía de Cumplimiento colombiana
Authors: Villalba Mercado Alexyx
Published: January 2021

Las garantías de cumplimiento se vuelven obligatorias en contratos de obra pública como ‘solución’ a los problemas de asimetría de la información y riesgo moral propios de dicho contrato; sin embargo, debe tenerse en cuenta que los seguros son en sí mismos fuente de riesgo moral. Por ello, es necesario establecer si las pólizas cuentan con el diseño adecuado para disminuir el riesgo moral, y con ello, mermar el riesgo de incumplimiento en los contratos. En la parte analítica de este trabajo, se estudian datos empíricos y casos de incumplimiento, junto con el esquema obligatorio de la garantía de cumplimiento, y se logra establecer que, si bien la póliza protege el patrimonio del contratante en cualquier contingencia, puede que tenga efectos adversos en el contratista, ya que su diseño propicia el riesgo moral, la administración ineficiente de recursos y el incumplimiento.
Costos de transacción del acuerdo de paz en Colombia. Una interpretación desde la Escuela Neoinstitucional y el Teorema de Coase

Published: January 2021

Bajo el enfoque de la Escuela Neoinstitucional, la Teoría de Juegos y el Teorema de Coase, en el año 2009 realicé una investigación de Maestría en Derecho Económico en donde sostuve que, cuando el mecanismo de solución de conflictos es autocompositivo, los costos de transacción tienden a cero y, cuando en el mecanismo intervienen más partes (heterocompositivo), los costos aumentan. El presente artículo responde a la pregunta: ¿Cuáles son los Costos de Transacción del Acuerdo Internacional de Paz en Colombia?, delimitando con ello su marco geográfico y, dentro de su marco conceptual, teniendo como referencia la Negociación y la Mediación Internacional como Mecanismos Alternos de Solución de Conflictos Internacionales para alcanzar el Acuerdo Internacional. En ese orden, con la misma Teoría Económica y Análisis Económico del Derecho empleada en la Tesis de Maestría se demostrará que, en el Proceso de Paz en Colombia, usando la Negociación y la Mediación Internacional Pública, los costos antes, durante y después de la guerra fueron muy altos, pero se logró suscribir el Acuerdo Internacional de Paz necesario para asignar un recurso tan escaso es la paz. En la presente investigación se utiliza el método cualitativo bibliográfico.
Effect of capital conversion in the form of a reverse mortgage on benefits for senior citizens in major cities of Poland
Authors: Buzałek Przemysław , Czechowska Iwona Dorota
Published: January 2021

The aging of population is a common problem in the modern economy and finance. Reverse mortgage is one of alternative ways of raising citizens’ standard of living after retiring by obtaining financial benefits accumulated in a residential property. The aim of the study is to evaluate a role of equity release service in providing additional household income for senior citizens illustrated by the case of a reverse mortgage. This type of service consists in transformation of non-liquid, tied-up in property capital into liquid financial resources. Thanks to capital conversion, senior citizens can supplement retirement benefits without a need to leave their property. The research hypothesis verified in the study stated that benefits paid as equity release in the form of a reverse mortgage provided greater support for women than for men. That hypothesis was rejected.

W kwestii RODO w literaturze przedmiotu małą rolę poświęca się bankom spółdzielczym. Celem artykułu jest diagnoza przeprowadzonych zmian w zakresie ochrony danych klientów banku na skutek wejścia w życie rozporządzenia o ochronie danych osobowych, tzw. RODO. W celu określenia modyfikacji zaszłych w sposobie przetwarzania danych, dokonano analizy treści informacji komunikatów zamieszczonych na stronach internetowych czterech banków spółdzielczych.
Does bank resolution rule out the use of public funds? The case of the Podkarpacki Bank Spółdzielczy
Authors: Stopczyński Andrzej
Published: January 2021

On 15 January 2020 Polish resolution authority made a decision to launch the resolution of a regional cooperative bank. The aim of the resolution was to maintain the service of local government units, considered as the critical function of the bank. The tool used was a bridge bank combined with bail-in to subordinated bonds and unguaranteed deposits, including deposits from local government units. The author is of the opinion that the write-off deposits from public entities was a substitute of the insufficient amount of liabilities contractually eligible for bail-in, served as the instrument enhancing credibility of resolution as well as protecting other creditors from excessive losses (i.e. mitigating contagion risk). The presented case of bank resolution, has been assessed as an example of intentionally bending of the stiff BRRD rules to an unusual case to find the practical, socially acceptable solution. By comparing this case with resolution of other small banks in the EU, the author argues that national authorities seek to limit the scope for bail-in and try to use the financial arrangements within the resolution of small local banks as more secure for the banking sector and socially acceptable manner.
Wokół istoty wykluczenia finansowego. Ujęcie przeglądowe
Authors: Warchlewska Anna
Published: January 2021

Artykuł zwraca uwagę na problem niejednoznaczności w opisie zjawiska wykluczenia finansowego. Dotychczasowe podejście do problemu wykluczenia finansowego w literaturze wskazuje na rozbieżności w pomiarze zjawiska, tak co do rodzaju, jak i obszaru. Skutkiem owych rozbieżności jest m.in. odmienne podejście metodologiczne oraz brak jednolitych miar pomiaru wykluczenia finansowego. Celem opracowania jest przedstawienie różnic terminologicznych w opisie i pomiarze zjawiska wykluczenia finansowego. Ponadto, dokonano charakterystyki etapu przejściowego, wyłączenia finansowego, który powinien stanowić etap pośredni między włączeniem finansowym a wykluczeniem finansowym.

A field experiment was conducted during winter, 2015-16 with the objective to investigate the effect of bread wheat cultivars (Abu-Ghraib3, Ibaa99, and Alfeteh) and seed priming 100, 100, 150 mg L-1 of benzyl adenine, salicylic acid, gibberellic acid (GA3), respectively, ethanolic extract of Salix Sp., water extract of Glycyrrhiza glabra and distilled water (control) on grain growth rate (GGR), effective filling period (EFP) and accelerating of physiological maturity. Randomized complete block design with three replicates was applied. GA3×Ibaa99 surpassed others in grain yield (7.432 tonne ha-1) when gave the highest grain weight (45.13 mg grain-1) and GGR (1.5 mg grain-1 day-1) with the fastest time to start and end EFP (5 and 34 days), which mean it reached to physiological maturity earlier. It can be conclude that seed priming led to accelerating the physiological maturity with increase grain yield through enhancing GGR and EFP in bread wheat.
Study on diversity of foliar trichomes in thirty accessions of okra (Abelmoschus esculentus (L.) Moench.)
Authors: Krishnakumar K. , Rajeena P. , Veena V.
Published: January 2021

Foliar epidermal features of thirty accessions of okra (Abelmoschus esculentus) were studied with the aim of using these features to identify them in the vegetative stage during hybridization experiments. Quantitative and qualitative micromorphological characters, distribution of both glandular and eglandular foliar trichomes in thirty accessions of okra were characterized. An indumentum of variable density and texture formed of wide variety of glandular and eglandular trichomes on both surfaces of leaves. Among the thirty accessions of okra studied, both glandular and eglandular foliar trichomes showed considerable diversity in their qualitative and quantitative micro morphological characters. Diversity of these epidermal appendages is separated into eight main types. Eglandular conical type trichomes were the most abundant on both leaf surfaces of all the accessions examined. Accessions like Pusasawani and IC-117251 could be demarked due to the occurance of stellate trichomes. Forked type was delimited to accessions like Arkaanamika, IC-99746, IC-111514 and IC-111517. These variations in morphology and distribution of the foliar trichomes emerged as an important tool to identify the diverse accessions of okra during breeding programme.
ISSR marker based diversity assessment of Piper spp. in Bay Islands, India
Authors: Abirami K. , Baskaran V. , Simhachalam P.
Published: January 2021

Inter-simple sequence repeat (ISSR) analysis was used to study the genetic diversity of Piper spp. with its relative genus Peperomia pellucida. Among the 38 ISSR primers used, 10 primers generated 1083 bands, of which seven (80.8%) were polymorphic. The maximum polymorphism were obtained from the primers UBC 881, UBC 889, UBC 848 and UBC 830. Cluster analysis grouped the species studied into two major clusters. One cluster comprised the different accessions of Piper nigrum and is distinct from the other species of Piperaceae. The other cluster grouped the four species of Piperaceae namely Piper longum, Piper sarmentosum, Piper betle and Peperomia pellucida. The variability studies also revealed that the ISSR marker could group the accessions within the same species based on their similar geographical origin. Assessment of genetic diversity among the different species of the family Piperaceae through ISSR marker would help in rapid identification of polymorphism, assist in future germplasm collection, conservation and domestication programmes.

Authors: Akoijam Yaiphabi , Devi Angom Sarjubala , Singh Elangbam Jadu
Published: January 2021

In the present study four different types of organic solid wastes namely: sugarcane waste, fish waste, flower waste and pineapple waste were selected and amended in soil. Plantation of saplings of Solanum melongena were done in the amended soil and changes in the growth pattern, biomass and soil characteristics were observed by comparing with unamended pots. It was observed that amendment of flower waste leads to an overall increase in the productivity of crop. On an average there was an increase of 11.7cm in height, 13 number of leaves, 5cm in root length and 3.4 g of biomass in the flower waste amended pots. Sugarcane and fish wastes amendment did not show positive impact on the crop. Pineapple wastes showed positive change. Soil moisture, organic C and N increased in all types of amendments. Available K increased only in flower and pineapple wastes amendment. There was significant correlation between crop and soil characteristics showing faster release of K in flower waste led to an increase in production of the crop.

Microscopic plant parasitic nematodes are round worms that feed on plants and damage them. The most common and serious amongst the nematodes is the root-knot nematode found throughout the country with a very wide host range of cultivated crops. Brinjal (Solanum melongena) crop yield is considerably reduced by root-knot nematodes particularly Meloidogyne incognita. Root-galls of brinjal caused by Meloidogyne incognita can be controlled effectively by using the bio-agents and botanicals which in turn increases the yield and plant growth. Present study explored the effect of leaf extracts of certain plants on the root-knot development, plant growth and nematode multiplication in pot experiments. Extract treated and nematode inoculated plants showed improvement on growth over untreated inoculated plants and reduced the disease development. Five (viz., margosa, marigold, datura, hemp and tobacco) leaf extracts, irrespective of concentration, apparently induced tolerance in inoculated plants as evidenced by better plant growth in comparison to control and suppressed the multiplication of nematode which resulted in low root-knot index. Margosa (Azadirachta indica) leaf extract suppressed the nematode multiplication, reduced root galling and improved the plant growth of inoculated plants. Margosa and marigold (Tagetes erecta) leaf extracts were found more effective in controlling the root-knot development than the leaf extracts of hemp (Cannabis sativa), datura (Datura metel) and tobacco (Nicotiana tabacum). Higher concentrations (20 ml/plant) of leaf extracts were found to be more effective in controlling the root knot development. Based on our observations, it may be concluded that margosa or marigold extract treatment of brinjal seedlings prior to transplantation can avoid severe damage by suppressing the nematode multiplication and inducing the tolerance in treated inoculated plants.
