In companies / agencies need an information system for purchasing goods so that it can be done computerized and not done using Microsoft Office. Purchasing goods is an overall process used to hold something necessary in meeting the needs of goods in the company. The need for goods is very important in supporting the work process in a company / agency, the unavailability of goods can hamper performance. Supervision of requests is generally less than optimal, because many procurement request files are still stored in the File and sometimes some are torn and lost, so a system is needed that handles the request process. The process of making requests for goods in the procurement section has difficulty updating the availability of goods so that it hampers the process of demand for goods, so a module is made to be able to monitor the process of demand for goods and activities related to the purchase of goods. So that the procurement department can speed up the process of disbursing data, minimizing errors and data loss. The system that is created later uses a Visual .Net programming language with a MySQL database, all processes will be stored into the MySQL database.

Published: August 2023

Fusarium oxysporum f. sp. lycopersici causing tropical wilt of tomato is a destructive phytopathogen. To study bio efficacy of fungal bio agents, fifteen isolates of Trichoderma species were isolated from rhizosphere soil of healthy tomato plants. Among the isolates, TA12 showed higher antagonistic efficacy against the pathogen. Upon analysis of the rDNA of internal transcribed spacers (ITS) and molecular data, the isolate was identified as Trichoderma atroviride. The in vitro antagonistic assessment indicated that the T. atroviride isolate caused significant inhibition of F. oxysporum f. sp. lycopersici. Trichoderma atroviride (TA12) showed antagonistic activity against F. oxysporum with mycelial inhibition of 71.25%. The culture filtrates of Trichoderma atroviride exhibited its antifungal activity against F. oxysporum with a suppression of 77.77%. Moreover, the ethyl acetate extracts of T. atroviride TA12 showed the highest antifungal potency against F. oxysporum f. sp. lycopersici. The main bioactive constituents of T. atroviride were 6-pentyl - 2H-pyran-2-one, quinoline, phenol, 2-(6-hydrazino-3-pyridazinyl) and heptadecane. In conclusion, the isolate TA12 could be exploited to develop an effective biocontrol management practice for combating Fusarium wilt disease of Fusarium oxysporum f.sp. lycopersici in tomato.

Published: August 2023

Yellow mosaic disease caused by Tomato leaf curl New Delhi virus (ToLCNDV) causes 100 percent losses in ridge gourd under epidemic conditions, particularly in the tropics and sub-tropics of India. Plant breeding approaches led by the marker-assisted selection have gained increased momentum in virus resistance breeding to hasten the development of resistant varieties. In the present study, an effort has been made to identify molecular markers linked to yellow mosaic disease resistance loci in an F2 population derived from a cross between susceptible ‘Arka Prasan’ and resistant ‘IIHR-Sel-1’ of ridge gourd. All the molecular markers were amplified in parents, and one polymorphic marker clearly distinguished the contrasting parents. The primers LaRGAP 63 produced a polymorphic DNA fragment that co-segregated with yellow mosaic disease reaction phenotypically in the F2 population. The identified marker will be helpful to the breeders for introgression of resistance loci into the elite background.
Qualitative and organoleptic evaluation of immature cashew kernels under storage
Authors: Sharon Jacob  , A Sobhana
Published: August 2023

Cashew cultivars, based on flowering behaviour, are categorized into three types, viz., early season, mid-season and late season. In late season type, the harvesting of cashew nuts coincides with the rainy season during which the quality of matured nuts are affected by increased pest and disease attack. This loss can be reduced if the nuts are harvested before it reaches its complete maturity. In this context, present study was conducted in immature cashew kernel to find out suitable storage treatments to enhance the shelf life. Immature cashew kernels were stored in different concentrations of brine solution (5%, 10% and 15%), sugar syrup (50°B, 60°B and 70°B) and by drying in hot air oven until the moisture content of kernel reaches 2-3 per cent. Storage period was for four months and the observations like tannin content, microbial content and organoleptic qualities of kernels stored in each treatment were analysed at the beginning and at the end of the storage. The treatment with 10% brine and 70°B sugar syrup for four months were found as best for storing immature cashew kernels.

Published: August 2023

A study was undertaken to assess the suitable drying methods for retention of quality parameters of drumstick (Moringa oleifera Lam.) leaf powder. The experiment was laid out in Factorial CRD involving three methods of drying (T1: Sun drying, T2: Shade drying and T3: Cabinet tray dryer) with three pre-treatments (B1: Unblanched, B2: Blanched with plain water and B3: Blanched followed by KMS dip) replicated three times. All the pre-treatments had significant effect on biochemical characteristics of drumstick leaves. Among the pre-treatments, unblanched leaves (B1) retained higher nutrient contents compared to other pre-treatments. The results ofthe investigation revealed that among the three different drying methods, shade dried sample was found to retain better nutritional properties. Significantly maximum values for moisture (11.18 %), ascorbic acid (156.27 mg/100g), vitamin-A (22.71 mg/100g), iron (16.54 mg/100g), oxalate (378.66 mg/100g), antioxidant activity (77.11%) and phenol (140.04 mg/100g) were recorded in shade dried sample. The interaction effect between pre-treatment and drying methods showed variation in results. However, the treatment combination T1B1 (Unblanched sun dried) was found to retain high protein (26.43 g/100g), magnesium (318.70 mg/100g) and potassium (1378.79 mg/100g) whereas T2B1 (unblanched shade dried) showed higher ascorbic acid (179.47 mg/100g), saponin (3.66 %), oxalate (541.47 mg/100g) and antioxidant (80.33 %) than rest of the treatment combinations.

Authors: RATHINAKUMARI CAROLIN , G Senthil Kumaran
Published: August 2023

Onion is the one of the important vegetable crops cultivated in India. Multiplier type onion is one among the three major types of onions. Tamil Nadu accounts for five per cent of country’s area under onion and more than 70 per cent of the area is cultivated by small onion (Allium cepa var. aggregatum). Around 90 per cent of country’s multiplier onion is produced from Tamil Nadu. Detopping is one of the steps in the on-farm processing carried out after harvest. Presently this is done manually by farm women. Individual onions are picked and detopping is done by using sickle. This operation is time consuming and highly drudgery in nature. An Onion detopping machine to remove the foliage after harvest was designed and developed in the present study. This machine has a capacity of 370 kg/h against 30 kg/h manual practice and works with an efficiency of 98%. The unique design of the detopper is that it is suitable for all sizes of onions. Also, the cluster is intact after detopping, which is very important requirement. This multiplier type onion is grown in Nagamangala (Tk), Mandya (Dt.) of Karnataka State. Two farmers of this area have installed this machine and running a successful enterprising. Cost involved in using this machine is Rs. 200 per quintal against Rs. 500 per quintal by manual detopping. Owing to the higher capacity by mechanization, the farmers will be able to process the higher volume of produce within a short span of time. Hence, this will facilitate the farmers to sell the produce, get good market price and earn higher returns.

Published: August 2023

Morphological and molecular diversity of Ganoderma species causing basal stem rot of coconut in Southern dry tracts of Karnataka, India was carried out during 2016-17. A total of 20 isolates were isolated from Chitradurga, Chikamagalore, Hassan and Tumkur districts of Karnataka and were identified based on morphological and molecular characteristics. Sporocarps and diseased root bits were found as good source for isolation of Ganoderma. In all the isolates there were high variability in cultural, morphological and molecular characteristics. The dendrogram generated from the cultural and morphological characteristics showed clear variations among Ganoderma isolates and formed two main clusters, one cluster consisted of 13 isolates and another cluster consisted of 7 isolates. Several isolates showed 100 per cent similarity in the morphological characters regardless of their geographical origin. All the Ganoderma isolates amplified a fragment of 650 bp with fungal universal primers (ITS1 and ITS4). The ITS gene sequences of five isolates viz., CG1 (MK 681870), CG7 (MK681871), CG11 (MK681872), CG14 (MK681873) and CG20 (MK681874) were deposited in NCBI gene bank. Taxonomic comparison of the isolates with NCBI database proved that the isolates were genetically related to Ganoderma spp. with 80-100 per cent identity. However, all the tested isolates could not amplify G. lucidum species specific markers which indicate its absence in the region. The phylogenetic analysis of the Ganoderma isolates (ITS1 and ITS4) of coconut with other known species of Ganoderma from GenBank emphasized the close relationship with India, China and Sri Lanka isolates. The isolate CG1 grouped with Ganoderma carnosum (KR 733545.1) with 98.97 per cent identity which is isolated from Sri Lanka and CG14 and CG20 grouped with G. applanatum (MF 072395.1) and G. gibbosum (OM 350473.1) with 98 to 99 per cent identity and CG7 and CG11 isolates of coconut grouped into distinct sub cluster and clearly indicated the species diversity in Ganoderma infecting coconut in Southern Karnataka.

Authors: Kanade Nandkishor , K S Shivashankara , R M Kurian , M Sankaran
Published: August 2023

In mango, leaf and fruit volatile aroma profiles are variety specific which can be used as fingerprint of a variety. Such biochemical markers can also discriminate the nucellar and zygotic seedlings in polyembryonic mango varieties. In order to validate the applicability of volatile as well as phenolic acid profiles as biomarkers, the open pollinated seedlings of three polyembryonic varieties of mango were compared with their mother trees. Leaf volatile and phenol acid profiling were done using Gas Chromatography/Mass Spectrometry (GCMS) and Liquid Chromatography/Mass Spectrometry (LCMS) methods respectively. The sesquiterpene hydrocarbons were the most abundant in all the genotypes studied. Monoterpenoids were the major compounds in cultivars Vellaikolumban and Olour, while the sesquiterpenoids were the major compounds in cv. Turpentine. While terpinolene was the major monoterpenoid compound in Vellaikolumban and limonene in cv. Olour, the sesquiterpene á-gurjunene was the major compound in cv. Turpentine. Volatile profiling showed clear differences between the varieties but was similar within a variety. Among the 15 phenolic acids quantified in the leaves, P-coumaric acid, gallic acid, and ferulic acids were predominant whereas, vanillic acid, syringic acid, gentisic acid, benzoic acid, and sinapic acids were low in quantity. Phenolic acid profile did not show significant diversity among the varieties and therefore cannot be used for identification of varieties. The volatile profiling can be used for the identification and differentiation of polyembryonic mango genotypes.

In another set of experiment, soil incorporation of Parthenium hysterophorus, Urtica dioicaandLantana camarawere found to reduce root rot incidence with high germination and pod yield. Among the bioproducts and botanicals tested, foliar spray of cow dung extract (50%) reduced angular leaf spot, rust and bacterial blight severity by 51, 69 and 25 per cent, respectively. Among the fungicides, foliar application of azoxystrobin 23 SC (0.1%) and difenoconazole 25EC (0.025%), also reduced angular leaf spot and rust severity by 93 and 90 per cent, respectively. Among different insect pest management strategies under field conditions, cartap hydrochloride and batain seed extract registered low sucking bug (Chauliops choprai) population. Integrated approaches including bio-agents, botanicals along with chemicals for managing these diseases and insect-pests were found appropriate options. Out of six different IPM modules evaluated, seed treatment with carbendazim along with foliar spray of 0.1% azoxystrobin and cartap hydrochloride resulted in lowest root rot, rust, angular leaf spot, bacterial blight and Chaulopsis choprai bug population in French bean.

Presentación
Prácticas y experiencias: cuerpos en juego
Authors: Césaro Aldo Román
Published: August 2023

El siguiente ensayo propone, por un lado, compartir un marco conceptual sobre dos palabras muy utilizadas en el campo de la educación contemporánea: prácticas y experiencias. Para ejemplificar el  desarrollo de las categorías, se usan como referencias para reforzar el análisis, tres imágenes de  diferentes prácticas, ancladas en lo que se podría denominar como, prácticas/experiencias de lo  absurdo; de lo ambivalente; del ritual. Por otra parte, se presenta una síntesis metodológica de  observación de prácticas y experiencias apelando a diferentes formas de clasificación, que pueden  resultar adecuadas como estructura o modelo para el registro y análisis de diferentes prácticas y  experiencias con acento en los juegos, los deportes y otras manifestaciones performáticas del cuerpo.

Este trabajo tiene como objetivo principal difundir la existencia de la biblioteca personal de César S. Vásquez conservada en el Centro de Documentación Histórica perteneciente al ISEF N° 1 “Dr. Enrique Romero Brest”. Se realizará un recorrido sobre su llegada a este repositorio, cómo está organizada y los modos de acceso a la misma. También se detallarán algunos documentos que este archivo personal atesora con la intención de realizar una aproximación a nuevas líneas de investigación. En particular, se hará foco en las compilaciones documentales realizadas por Vásquez y en especial sobre un documento que recopila gran cantidad de recortes periodísticos que recorren toda su gestión al frente de la Dirección General de Educación Física desde 1938 hasta 1947. Por su parte, el abordaje de un conjunto de documentos personales para la historización de cuestiones institucionales, presenta un desafío y un incentivo, dada la naturaleza de estas fuentes primarias, como complemento de la abundante producción académica generada hasta la actualidad vinculada a este ente gubernamental y sus distintas iniciativas. De igual modo, estos materiales contienen valiosa información acerca de las distintas instituciones por las que este personaje transitó su vida profesional, aspecto que invita a la investigación de dichas entidades en particular como así también, las posibles relaciones entre éstas y la Dirección General que reguló la Educación Física nacional durante casi una década.
Foundation of Islamic Education Curriculum (Study of Q.S. Al-‘Alaq 1-5) Perspective of Transcendental Structuralism
Authors: Subakat Rahayu , Harahap Ahmad Yunus Mokoginta
Published: August 2023

The researcher's academic anxiety sees the problem of lagging in Islamic education because the curriculum foundation is not strong. The existence of a long debate regarding the form of Islamic education curriculum demonstrates the confusion about the basic structure or foundation. Philosophically, Q.S. al-‘Alaq 1-5 contains the message of the basic values of Islamic education. The theoretical claim in this paper is Q.S. al-‘Alaq 1-5 which is elaborated on the theory of transcendental structuralism that produces the basic concepts of the Islamic education curriculum. Implicitly, this study can be used as a theoretical framework to analyze the problems of the Islamic education curriculum in general. This study aims to explain the relationship between Q.S. al-‘Alaq 1-5 with the foundation of the Islamic education curriculum. The results of this study indicate that based on Q.S. al-‘Alaq 1-5, the foundation of the Islamic education curriculum consists of epistemology as a way of thinking, world view as a view of world, and ideology as a value order oriented to the integration of spiritualawareness, rationality awareness, ethical awareness, technological awareness and awareness of social transformation. The novelty of this paper is found in the analysis of transcendental structuralism of the verses of the Qur'an which produces the theory of Islamic education. This research can be said as the theorizing of the Qur’an or the science of Islam.
The everyday work of farm advisors as interface bureaucrats in greening French agricultural policies
Authors: Clement Floriane , Labarthe Pierre , Plumecocq Gaël
Published: August 2023

For the last three decades, public agricultural policies in France and in Europe have progressively integrated environmental objectives through a wide range of instruments. Whereas a large body of research has examined the extent to which the greening of agricultural policies has shaped farmers' decisions and practices, few studies have considered how these normative policy orientations may trigger tensions within the agricultural bureaucratic apparatus, and notably among local farm advisors who play the role of interface bureaucrats. In this article, we have explored how farm advisors from different types of advisory structures develop multiple subjectivities and deal with the tensions that they face when navigating between policy goals, professional norms, and their personal beliefs and values. Drawing on plural qualitative methods, we focus on the implementation of two national public agroecological schemes in southwest France that support the emergence and facilitation of farmers' groups engaged towards agroecology. We find that organizational strategies shape the type of tensions advisors face and their ability to manage these. The type of policy instrument we considered also matters in the forms of creative bricolage that farm advisors develop: in the case of organizational instruments based on farmers' participation, maintaining relationships with farmers is critical to give meaning to their work. If such instruments enlarge the creative space of farm advisors, the schemes we examined also hold in-built limitations in empowering farm advisors as they fail to address the structural constraints that shape agroecological transitions.
A comparison of shear bond strength of immediate and delayed bonding of brackets to FRC bars using various orthodontic adhesives
Authors: Heravi Farzin , Moazzami Saied Mostafa , Kerayechian Navid , Nik Elham
Published: August 2023

Background: Fibre reinforced composite bars (FRC) have applications as bonded retainers, space maintainers and anchorage/movement units. However, the bond strength of attachments to FRC anchorage bars is unknown.

Aims: To compare the shear bond strengths of brackets bonded immediately to FRCs with different orthodontic adhesive systems and bonded with the same adhesives after a 48-hour delay, abraded with a diamond bur and etched with phosphoric acid.

Method: One hundred and five recently extracted upper premolars were randomly assigned to seven groups (N = 15 teeth per group). FRCs were bonded to the buccal surfaces of the teeth and stainless steel orthodontic brackets were bonded to the FRCs with the following adhesive systems: Group 0 (Tetric Flow); Groups 1, 2 and 3 (Immediate bonding with chemically cured, no-mix and light cured composites, respectively, the bars covered with Tetric Flow); Groups 4, 5 and 6 (Bonding to FRCs delayed 48 hours, then bonded with chemically cured, no-mix and light cured composites, respectively, the bars covered with Tetric Flow). The FRC bars in Groups 4, 5 and 6 were abraded with a coarse-grit diamond bur before bonding the attachments to the bars. The shear bond strengths (SBS) were measured with a universal testing machine, and the adhesive remaining on the teeth after debonding was scored with the Adhesive Remnant Index (ARI). Data were analysed using analysis of variance (ANOVA), Duncan’s post-hoc and Fisher’s Exact test.

Results: There were no statistically significant SBS differences between Groups 0 (Mean SBS: 9.56 MPa), 1 (Mean SBS: 9.74 MPa), 2 (Mean SBS: 10.72 MPa) or 3 (Mean SBS: 9.54 MPa). Groups 4, 5 and 6 (Bonding delayed by 48 hours) had SBSs of 11.79 MPa, 11.63 MPa and 13.11 MPa, respectively, and were significantly higher than the SBSs in Groups 1, 2 and 3 (Immediate bonding). There were no significant differences in ARI scores among the groups.

Conclusions: The mean SBSs in all groups fell within the clinically acceptable range (> 7 MPa). The combination of a 48-hour delay between placement of an FRC bar and bonding an attachment, abrading the FRC with a diamond bur and etching with phosphoric acid resulted in higher bond strengths.

Objective: To compare the shear bond strengths (SBS) of stainless steel brackets bonded to artificially-aged composite restorations after different surface treatments.

Methods: Forty-five premolar teeth were restored with a nano-hybrid composite (Tetric EvoCeram), stored in deionised water for one week and randomly divided into three equal groups: Group I, the restorations were exposed to 5 per cent hydrofluoric acid for 60 seconds; Group II, the restorations were abraded with a micro-etcher (50 μm alumina particles); Group III, the restorations were roughened with a coarse diamond bur. Similar premolar brackets were bonded to each restoration using the same resin adhesive and the specimens were then cycled in deionised water between 5 °C and 55 °C (500 cycles). The shear bond strengths were determined with a universal testing machine at a crosshead speed of 1 mm/min. The teeth and brackets were examined under a stereomicroscope and the adhesive remnants on the teeth scored with the adhesive remnant index (ARI).

Results: Specimens treated with the diamond bur had a significantly higher SBS (Mean: 18.45 ± 3.82 MPa) than the group treated with hydrofluoric acid (Mean: 12.85 ± 5.20 MPa). The mean SBS difference between the air-abrasion (Mean: 15.36 ± 4.92 MPa) and hydrofluoric acid groups was not significant. High ARI scores occurred following abrasion with a diamond bur (100 per cent) and micro-etcher (80 per cent). In approximately two thirds of the teeth no adhesive was left on the restoration after surface treatment with hydofluoric acid.

Conclusion: Surface treatment with a diamond bur resulted in a high bond strength between stainless steel brackets and artificially-aged composite restorations and was considered to be a safe and effective method of surface treatment. Most of the adhesive remained on the tooth following surface treatment with either the micro-etcher or the diamond bur.

Published: August 2023

Background: Mild Class III malocclusions can be treated by upper incisor proclination and lower incisor retroclination following extraction of the lower first premolars.

Aims: To compare the skeletal, dental and soft tissue changes in Class III patients treated with fixed appliances, Class III traction and lower first premolar extractions with the changes in a group of untreated Class III patients.

Methods: The Treatment group consisted of 30 Class III patients (Mean age 13.69 ± 1.48 years) who were treated by upper and lower fixed appliances, Class III intermaxillary traction and lower first premolar extractions for 2.88 ± 1.12 years. The Control group consisted of 20 untreated Class III patients (Mean age 13.51 ± 0.95) matched for age and gender. The T1 to T2 changes in the treated and untreated groups were compared using a paired t-test while differences between the two groups were compared with an independent t-test.

Results: During treatment, the upper incisors were proclined about 1 degree and the lower incisors were retroclined 8 degrees. Small, but statistically significant changes in SNB, Wits and the overlying soft tissues accompanied the changes in incisor inclination. At the end of treatment a positive overbite and overjet were achieved. The increase in lower facial height in the Treatment group was comparable with the change in the Control group.

Conclusions: A range of mild to moderate Class III malocclusions can be treated by dentoalveolar compensation.
