Improving Productivity of Small Farmers by Bio-Rational Soil Management: II. The Case of Horticultural Crops
Authors: J Franco
Published: December 2022

Production of horticultural crops in the Andean region of Bolivia is low as a result of various abiotic and biotic soil constraints, and the recourse to pesticides and fertilizers is frequently too expensive. Agricultural soils in this region of Bolivia are generally characterized by a low fertility with low content of organic matter and yields of most crops are limited. Therefore, it was proposed a recycling of organic waste into compost and the use of natural microbial soil inhabitants, - AMF and PGPR - to reduce chemical–dependence of small-scale agriculturists Several field trials located in Cochabamba department (Bolivia) with different horticultural crops were conducted. After four years. farmers are able to prepare with post-harvest organic residues and animal manures their own compost for its field incorporation at planting time (7-10 t/ ha). Several native isolates of PGPR and AMF were identified (B. amyloliquefaciens & G. intraradices, respectively). However with a commercial B. subtilis product (BZF 24WP), which later on was locally multiplied and formulated, and a Bolivian commercial mycorrhiza of G. fasciculatum (DESAmic), a biofertilizer was formulated and evaluated in several trials with different horticultural and orchard crops in farmer fields showed both plant growth promoting effect (horticultural and orchard crops:42.0 to 98.0 %). It was also observed a suppressive/inhibitory soil borne diseases effect. Therefore, it was also showed that micro-scale composting production based on organic waste from rural post-harvest residues in combination with animal manures, represent an alternative to chemical fertilizers

Comparison between Black Hole and Flooding Attack in Mobile Ad-hoc Network and their Simulation Study
Authors: Al Maamari Amal S. , K.Salih Nadir
Published: December 2022

Mobile ad hoc network (MANET) is dynamic in nature and vulnerable for several attacks to be arising in it. Mobile nodes frequently disconnect and join the network; they can arbitrarily moves from one place to another. In present-day wireless communication scenario, Mobile ad hoc network (MANET) plays a very important role, as it consists of many autonomous nodes which communicate together to form a proper communication network. Each node in a network will move in random path, so that nodes direction will change frequently. This paper describes the features, application, flooding attack and black hole attack in the MANET implemented on AODV protocol. The simulation work is carried out in Network Simulator (NS2.34). The performance analysis is done Nodes with 20 to 60 nodes were used in the AODV routing protocol simulation to produce energy-efficient outcomes, with the flooding attacks and the interruption of blackhole attacks. The average delay, routing overhead, packet drop rate and packet delivery rate are calculated. By the simulation it has been evaluated that in flooding attack the routing overhead is more as compared to the black hole attack. A comparative study is also done on these parameters for all three scenarios. Also we simulated the attack in various wireless ad-hoc network scenarios and have tried to find a response system in simulations.

Authors: KIZILTAN Ömer , BAYRAKTAR Olcay , DOMBAYCI Mehmet Ali
Published: December 2022

Felsefe kültüründen bahsedebilmek için özellikle tarihsel süreçte izi sürülebilir bir devamlılık gereklidir. Son yüz yılda ülkemizde bu devamlılığın daha çok yükseköğretim kademesiyle sınırlı kaldığı ileri sürülebilir. Ancak toplumda bir felsefe kültüründen bahsedebilmek için bunun yükseköğretim kurumlarının dışına da taşmış olması gerekir. Bu noktada, yükseköğretimdeki felsefe gelenekleri ve kültürü ülkeye veya medeniyete özgü düşünme biçimleriyle ilişkide olmalıdır. Ülkeye veya medeniyete özgü düşünme biçimleri millî kültür ve halk kültürü gibi kavramlar içinde ifade edilebilir. Bu açıdan, Türkiye özelinde, felsefenin halk kültürüyle buluşup buluşmadığı sorusuna dolaylı yollardan yanıt aranmaya çalışılmıştır. Bu amaç doğrultusunda Cumhuriyet’ten itibaren yükseköğretimde felsefe kültürüne etki eden başta kuşak farklılıklarına değinerek yükseköğretim düzeyinde gelenekler, problemler ve konu alanlarındaki farklılaşma ortaya konulmuş; devamında ise dernekleşme çabaları, felsefe dili tartışması, çeviri faaliyetleri gibi konulara da değinilerek ülkemizdeki felsefe kültürünün halk kültürü ile ilişkisi ele alınmıştır. Sonuç ve öneriler kısmı ile de felsefe geleneklerinin bir tür felsefe kültürüne dönüşerek kendi dışına açılmasının imkânları üzerinde öneriler ortaya konulmuştur.
Michael J. Sandel’in Piyasa Ahlakı Eleştirisi: Yozlaşan Toplum ve Tehdit Altındaki Demokrasi
Authors: DAĞ Umut
Published: December 2022

Bu çalışmada Michael J. Sandel’in piyasa ahlakına yönelik eleştirileri analiz edilecektir. Sandel’in temel iddiası olan, piyasa ahlakının toplumsal yaşama egemen olmasının sosyal iyilerin (social goods) yozlaşmasına neden olduğu ve bunun da demokrasi rejimini tehdit altında bıraktığı iddiası çalışmada ön plana çıkarılmıştır. Piyasa ahlakının sosyal yaşama egemen olması toplumu bir arada tutan sosyal iyilerin alınıp satılmasını meşru görmektedir. Bu meşruiyet Sandel’e göre iki açıdan ciddi sorunlar ortaya çıkarmaktadır. İlk olarak piyasa ahlakı, toplumu toplum yapan ve insanları bir arada ortak bir amaç etrafında yaşama imkânı sağlayan sosyal iyileri alınıp satılan birer metaya dönüştürmekle bu iyileri yozlaştırmaktadır. İkinci olarak da sosyal iyilerin yozlaştığı bir toplumda yurttaşların kendi kendini yönetme biçimi olarak tanımlanan demokratik rejim varoluşsal bir tehdit altındadır. Burada yapılması gereken en önemli şey ise piyasa hâkimiyetinin ahlaki anlamda sınırlandırılması olacaktır. Sandel’in sınırlandırılması gerektiğini düşündüğü piyasa ahlakı ise ancak onun yaslandığı liberalizmin ciddi bir biçimde eleştiriye tabi tutulmasıyla mümkündür. Çalışmanın dayandığı ana fikirlerden birisi de bu olacaktır.

Published: December 2022

Akibat peningkatan jumlah masyarakat yang terdampak Covid-19, pemerintah memberlakukan pembatasan kegiatan masyarakat (PPKM) untuk memutus mata rantai penyebaran virus tersebut, tidak terkecuali Provinsi Bali. Dengan adanya pembatasan ini tentunya akan memengaruhi jumlah emisi gas buang yang dihasilkan akibat penurunan jumlah perjalanan. Oleh karena itu, dilakukan analisis mengenai emisi gas buang dengan pelebaran jalan sebelum pandemi covid-19 serta emisi gas buang dengan pelebaran jalan setelah pandemi covid-19. Dalam penelitian ini, menggunakan pemodelan vissim yang telah dikalibrasi menggunakan data inventarisasi jalan, kecepatan, dan volume yang kemudian dapat menentukan keluaran emisi kendaraan. Uji validitas menggunakan uji Indenpendent Sample T-test. Dari hasil penelitian didapat bahwa penurunan emisi gas buang paling drastis terjadi di Simpang Nakula yaitu untuk gas karbon monoksida (CO) sebesar 26.646,27 gram/jam dan NOx sebesar 5.384,4  gram/jam. Sementara simpang yang lain juga mengalami penurunan. Untuk Simpang Soputan terjadi penurunan gas karbon monoksida (CO) sebesar 17.326,18 gram/jam dan NOx sebesar 3.371,18  gram/jam.

PENGARUH PENGGUNAAN OIL CATCH TANK (OCT) PADA MOBIL HYUNDAI AVEGA TERHADAP EMISI GAS BUANG DAN PRESTASI MESIN YANG DIHASILKAN
Authors: Yudhanta Ricko , Wira Praja Sumantri
Published: December 2022

Untuk mengoptimalkan udara murni yang masuk ke intake manifold dan mengurangi kadar emisi gas buang maka banyak dilakukan pengembangan-pengembangan. Salah satunya adalah penggunaan alat Oil Catch Tank (OCT). Fungsi utama dari Oil Catch Tank adalah untuk mencegah partikel minyak ataupun uap oli masuk kembali ke saluran intake. Blow by gas dari crankcase akan menuju tabung terlebih dahulu dan blow by gas ini akan terperangkap karena adanya media filter (steel wool) didalam tabung. Pemasangan Oil Catch Tank membuat udara yang masuk ke dalam intake terbebas dari partikel oli dan minyak.
Melalui hasil pengukuran, pada semua variasi Filter OCT, Kadar CO terendah terjadi pada range putaran mesin 1500 rpm. Sedangkan, pada putaran mesin 4500 rpm, konsentrasi CO menunjukkan angka tertinggi. Tetapi nilainya tidak melebihi ambang batas yang ditentukan yaitu sebesar 1,5 %vol. Kadar CO2 tertinggi sebesar 18.14 %vol terjadi pada saat terpasang alat OCT ukuran Filter 0.5 Micron di putaran mesin 4500 rpm. Kadar CO2 terendah sebesar 12.54 %vol terjadi pada saat mobil terpasang alat OCT ukuran Filter 0.5 Micron dicapai pada putaran mesin 1500 rpm. Kadar HC terendah sebesar 100 ppmvol terjadi pada pada saat terpasang alat OCT ukuran Filter 0.5 Micron di putaran mesin 4500 rpm. Kadar HC tertinggi sebesar 196 ppmvol dicapai di rentang 6000 rpm, terjadi pada kondisi mobil standar (tanpa alat OCT). Nilai torsi tertinggi sebesar 137 Nm terjadi pada kondisi terpasang alat OCT ukuran Filter 1 Micron di putaran mesin 3000 rpm. Nilai torsi paling rendah 81 Nm di putaran mesin 1500 rpm terjadi saat mobil standar (tanpa terpasang alat OCT). Nilai daya tertinggi sebesar 92.57 HP terjadi pada kondisi mobil terpasang Alat Oil Catch Tank (OCT) Ukuran Filter 1 Micron di putaran mesin 5500 rpm. Nilai daya paling rendah 21.18 HP di putaran mesin 1500 rpm terjadi saat mobil standar (tanpa terpasang alat OCT).
Dengan penambahan Oil Catch Tank (OCT) Ukuran Filter 0.5 Micron pada intake manifold, menyebabkan peningkatan nilai Torsi dan Daya yang dihasilkan oleh kendaraan. Serta penurunan nilai Emisi Gas Buang (CO, HC, CO2) yang dihasilkan lebih besar dibandingkan dengan kondisi mobil standar atau tanpa terpasang alat Oil Catch Tank (OCT). Dengan penambahan Oil Catch Tank (OCT) Ukuran Filter 1 Micron pada intake manifold, menyebabkan peningkatan nilai Torsi dan Daya yang dihasilkan oleh kendaraan, hal ini disebabkan komposisi udara yang akan masuk ke dalam intake manifold menjadi bertambah. Tetapi untuk penurunan Nilai Emisi Gas Buang (CO, HC, CO2) yang dihasilkan kendaraan, lebih kecil nilainya dibandingkan saat kendaraan terpasang Alat OCT ukuran Filter 0.5 Micron, karena endapan sisa oli yang terbawa bersama udara dapat tersaring dengan lebih baik di OCT ukuran Filter 0.5 Micron.

Authors: Akinkunmi Akanji Adedeji , L. A. Balogun
Published: December 2022

This research aims to identify the employee engagement and pricing systems used by manufacturing companies. This study used primary data, and 185 questionnaires were distributed to and collected from the industrial companies. For data analysis, descriptive statistics, the T-test, and a linear regression model were used. Regression analysis and the homogenous Duncan test were employed to test the hypotheses. The outcome demonstrates that pricing selections at 4.58 averages and 4.36 customer profits are made mostly using costing information. 4.09 and 4.06 analysis activities and purchase decisions are two more helpful areas where cost information is employed. The value of 2.125e3 for the F-statistic and the 5 percent level of significance show that the industries differ significantly. The number of orders placed with the company and the length of time it takes to complete all orders have a negative impact on the total cost of overhead by 3.1 percent and 22 percent, respectively, whereas the number of product batches and the number of production pieces have a positive impact on the total cost of overhead by 91.5 percent and 21.1 percent, respectively. The study comes to the conclusion that factors such as the quantity of orders that manufacturing companies receive, the duration of total production, the size of product batches, and piecemeal production all have a substantial impact on overall overhead expenses.

The livestock diseases were prioritized for high transmission potential as haemorrhagic septicaemia [HS] (2.51) followed by Peste des petits ruminants [PPR] (2.22), black quarter [BQ] (1.89), foot-and-mouth disease [FMD] (1.71), theileriosis [TE] (1.70), enterotoxaemia [ET] (1.54), anthrax [AX] (1.48), sheep and goat pox [SGP] (1.44), rabies [RA] (1.39), babesiosis [BA] (1.38), bluetongue [BT] (1.31) and fasciolosis [FA] (1.27) based on mean R0 values for Karnataka. The herd immunity threshold was high for HS [60.2%] followed by PPR [55.0%], BQ [47.1%], FMD [41.5%] and other diseases. The vaccination coverage required showed highest levels for HS, followed by PPR, BQ, FMD, TE, ET, etc. Thus, R0 values may be used for prioritizing livestock diseases by policy makers and for planning the necessary preventive measures. The herd immunity threshold and vaccination coverage obtained for livestock diseases will help in allocating the scarce resources for vaccination effectively and to prevent livestock diseases outbreaks in Karnataka.

The present study has quantified the economic impact of control of goat pox disease in India using a vaccine developed against the disease at ICAR-IVRI, applying an economic surplus model. The findings of the study have revealed significant benefits of Goat pox control programme using the vaccine. The potential change in total surplus, as a result of Goat pox control programme was ₹ 2.42 crore/annum. The change in total economic surplus and research and delivery cost were projected from 1999 (year of the start of the project) to 2030 after adjusting for the above adoption pattern. Using a long run discount rate of 7.50%, the benefits were compared to research and delivery cost and the NPV, IRR and BCR were calculated. The NPV, IRR and BCR of Goat pox control programme were ₹ 9.25 billion, 38% and 19: 1, respectively. Sensitivity analysis revealed that the benefits are most sensitive to assumptions regarding lower degree of immunity offered by the vaccine and higher discount rate.

The objective of this research was to predict the live body weight from morphological traits of Sirohi goat. Based on data of Sirohi goat of different age (0–3 months, 3–6 months, 6–9 months and 9–12 months) kept under All India Co-ordinated Research Project on goats for Sirohi goats (AICRP) at Livestock Research Station, Bojunda, Vallabhnagar, and Dabok areas of Udaipur, Rajasthan during the year 2017. Simple and multiple regression models were used to explore the live weight and 5 morphological traits while taking animal’s age and sex into consideration. Correlation between body weight and morphological traits at different ages were positive and strongly correlated (P≤0.01). Simple and multiple regression models were fitted with body weight as the dependent variable and morphological traits as independent variables. The coefficient of determination in different equations indicates that combination of heart girth, height at withers, body length, punch girth and rump height succeed in estimating body weight better than single morphological trait. It can be concluded that the best fitted multiple regression models including heart girth, height at wither, punch girth, body length and rump height may be considered best for prediction of body weight of Sirohi goat.

KVK-Kargil under its FLD programme, distributed Kroiler and Vanraja birds to selected tribal families belonging to two blocks of Kargil District and that were considered for the present investigation to carry out a comparative growth and production performance of the improved supplied variety with the existing deshi birds. The results revealed that body weights gain varies significantly among Kroiler, Vanraja and Desi chicken across the different age and were found to be 1.91Â±0.02, 1.78Â±0.02 and 0.62Â±0.014 at six months; 3.93Â±0.05, 3.64Â±0.07 and 1.48Â±0.01 at one year and 4.33Â±0.05, 4.07Â±0.06 and 1.87Â±0.01 at two years of age respectively. Similar trend were also observed in respect of all production parameters, be it age at first laying, numbers of egg production or egg weight. Numbers of egg produced during first cycle reveals the figure as 182.95Â±1.31,172.44Â±1.59 and 112.85Â±1.73 for Kroiler, Vanraja and Desi birds respectively and which differ significantly among each other. The study concludes that the Kroiler and Vanraja have better adaptability under free range system of production in cold arid condition of Kargil and can be a better alternative for existing Desi birds to augment the production and met the nutritional demand.

Published: December 2022

Result revealed that although of the respondents fell under low and medium adoption gap categories for most of the scientific management practices but still major adoption gap percentage was found in health care (47.4%), feeding management (42.9%) and calf management (31%). The health care practices which were not followed included screening of herd for mastitis and tuberculosis. Medium gap in feeding practices was observed in silage making, processing of feed and UMMB feeding. Practice of calf scour management was sometimes followed by majority of the respondents. Other practices which were never followed by majority of the respondents include practice of availability of foot dips at entrance, feeding milk replacer to calves, milking animals in milk barn and insurance of animals. State animal husbandry department, dairy cooperatives and farmers organisation working in those areas should disseminate knowledge about fodder preservation, health care and hygiene of animals as well as clean milk production which in return would prevent them from incurring economic losses due to disease outbreak and fetching them high price for the clean milk produced.

Published: December 2022

The present study aimed to isolate and characterize the Extracellular polymeric substance (EPS) producing bacteria from biofloc reared Nile tilapia (Chitralada) ponds. Distillery spentwash was used as a carbon source to maintain the C: N ratio at 10: 1 in the fish culture ponds and screening of bacteria were done fortnightly in 180 days culture. Out of 38 bacterial isolates, 7 isolates were found to produce EPS. Based on 16s rRNA sequence analysis the isolates were identified as Bacillus subtilis, B. megaterium, B. infantis, B. cereus, Pseudomonas balearica, P. mendocina and P. alcaligenes. The highest production of EPS was recorded in B. cereus (1.25 g/L). EPS extracted from Bacillus cereus was reported to have higher protein (89 Î¼g/ml) and B. subtilis possessed higher carbohydrate (753.75 Î¼g/ml). Maximum flocculating ability of 40.18% in B. cereus and higher emulsifying activity of 63.53% was observed in B. megaterium. The EPS extracted from B. infantis showed lower sludge volume index on its treatment with aquaculture sludge (15.38 ml/g). Absorption band in the range of 4,000/cm to 450/cm using FTIR analysis confirmed the presence of characteristic functional bands arising from polysaccharides, nucleic acids and proteins. The results indicated the presence of EPS producing bacteria in biofloc based Nile tilapia aquaculture systems.

Classé dans la catégorie ‘espèce vulnérable’ sur la Liste Rouge de l’UICN et du Bénin, l’hippopotame commun est fréquemment observé en dehors des Aires Protégées. L’étude visait à identifier les caractéristiques phytoécologiques des zones fréquentées par l’hippopotame commun le long de la Rivière Pendjari. Conduite dans les Communes de Natitingou et de Toukountouna au Nord-Ouest du Bénin dans les terroirs villageois, l’étude était basée sur 50 relevés phytosociologiques effectués suivant la méthode de Braun Blanquet. Les placeaux installés avaient tenu compte de l’homogénéité floristique des strates végétatives des habitats prospectés. 61 espèces végétales avaient été recensées et soumises à une Analyse de Correspondance Détendue (ACD) puis à une Classification Ascendante Hiérachique (CAH) pour construire les différents groupes écologiques. A partir de ces groupes, des indices de Shannon et de Piélou avaient été mesurés. Trois formations végétales composaient le biotope de l’hippopotame le long de la Rivière Pendjari avec des groupements végétaux spécifiques : la savane herbeuse caractéristique du groupement G1 à Hyparrhenia involucrata et Pennisetum purpureum ; la savane arbustive caractéristique du groupement G2 à Vachellia sieberiana et Crotalaria retusaI et la savane arborée caractéristique du groupement G3 à Desmodium gangeticum et Keetia venosa. Le groupe G3 était le mieux représenté en richesse spécifique avec 48 espèces suivi des groupes G2 et G1 avec respectivement 29 et 28 espèces. Ainsi, les espèces étaient mieux réparties dans le groupe G3 que dans les deux autres avec une diversité de Shannon de 4,90 bits et une équitabilité de Pielou de 0,88. Néanmoins, on a noté l’absence de plusieurs plantes préférées par les hippopotames traduisant une dégradation des terres de parcours. Des aménagements doivent être effectués autour de la Rivière Pendjari pour restaurer les parcours naturels.
Migrations agricoles et stratégies de reconquête du patrimoine familial au Togo : cas des Kabiyè dans la région des Plateaux
Authors: PALASSI Konga
Published: December 2022

Les Kabiyè sont un groupe ethnique du Nord Togo. Ils ont connu des vagues de migrations qui ont conduit certains vers le sud du pays, depuis l’époque coloniale allemande. Dans les fermes où ils s’installent, ils entretiennent les champs pour le compte des propriétaires fonciers. En contrepartie de leurs services, ils bénéficient de traitements variables selon les localités et selon les employeurs : salaire journalier ou mensuel, partage des récoltes, métayages ou exploitations concédées, cession à vie de terres de culture, etc. C’est de cette manière que certains immigrés ont acquis des propriétés foncières dans les lieux d’accueil. Au début des années 1990, suite aux troubles sociopolitiques qu’a connus le Togo dans son processus de démocratisation, nombre de ces immigrés ont été chassés par les autochtones et expropriés de leurs domaines. Après la crise, ils tentent de reconquérir ces patrimoines en s’organisant pour y retourner. L’article a pour objectif d’analyser les stratégies de reconquête du patrimoine foncier familial par les Kabiyè au sud du Togo. La démarche méthodologique est essentiellement qualitative de type socio-anthropologique. Comme résultats, on peut globalement retenir que ces migrants adoptent des stratégies pacifiques ou conflictuelles pour leur réinstallation et des stratégies de pérennisation pour préserver leurs acquis.
