Authors: Benlarbi Faiza , Stoker Pierre , Yousfi Mohamed 
Published: September 2018

BACKGROUND: Olive fruits have become extremely valuable because they have important nutrient properties and have shown positive benefits for human health. The chemical composition and organoleptic characteristics may be influenced by genotype and some agronomic factors like olive drupe harvesting date. OBJECTIVE: In this study, the greatest interest is to clarify and to give more information for Algerian Olea europaea L. by investigation of their total phenolic and flavonoid contents, phenolic compounds identification, total antioxidant capacity and antihemolytic activity at two levels of the olive ripening process. METHODS: Colorimetric methods were used to quantify total phenolic and flavonoid contents. The phenolic composition was done by HPLC technique. The antioxidant activity was assessed by measuring radical scavenging activity against 2,2’-azino-bis-(3-ethylbenzthiazoline-6-sulfonic acid) radical cation (ABTS• +) expressed as Trolox Equivalent Antioxidant Capacity (TEAC), Ferric Reducing Antioxidant Power (FRAP) and antihemolytic activity. RESULTS: The harvesting time effect on HPLC analysis of olive fruits was significant. Interestingly, the phenolic composition of the olive fruits differed greatly between samples. Two compounds usually not described in olive fruit were identified, namely morine dihydrate and coumarin. The amounts of total phenolics varied widely in the investigated extracts and ranged from 495 to 2325 mg GAE/100 g for black olives and from 865 to 2387 mg GAE/100 g for green olives, whereas the flavonoids content expressed as rutin equivalent per 100 gram of defatted dry matter was ranged between 155 and 354 mg/100 g for green olives and between 214 and 260 mg/100 g for black olives. The antioxidant activity of black and green olives ranged from 5.86 and 4.88 to 59.44 and 50.50 mM Trolox equivalents respectively, while ferric reducing antioxidant power (FRAP) was within the range of 0.36 and 0.31 to 4.41 and 3.04 mM Fe(II) respectively. Majority of extracts exhibited a beneficial antihemolytic effect. CONCLUSIONS: Results showed that the level of maturation influences the chemical composition, antioxidant and bioactive properties. Consequently, this allows us to estimate the best and optimal harvest time.

Metal Injection Molding (MIM) merupakan proses manufaktur yang mempunyai 4 tahapan proses utama yaitu mixing, injection, debinding dan sintering. MIM telah banyak diterapkan diberbagai bidang industri manufaktur seperti automotive, tool steel cutting, komponen elektronik, alat-alat kesehatan atau kedokteran, komponen senjata, fashion dan lain-lain. Proses Debinding merupakan salah satu proses yang sangat penting dalam proses MIM, dengan berbagai keragamannya. Solvent debinding adalah cara memisahkan/ekstrasi atau menghilangkan polimer dari serbuk logam/ feedstock. Kelebihan dari solvent debinding ini adalah larutan yang digunakan dapat di daur ulang sehingga mengurangi biaya produksi produk MIM. Maka penelitian ini diperlukan untuk memenuhi kebutuhan industri dan memperkaya proses-proses debinding dengan berbagai larutan (solvent) kima. Studi awal solvent debinding pada feedstock Fe2%Ni hanya dibatasi untuk menhilangkan binder jenis paraffin wax, karena penggunaannya hampir di setiap feedstock MIM terdapat paraffin wax. Parafin Wax dilarutkan dan direndam dengan menggunakan ethanol, n-hexane, heptana dengan parameter waktu 2,3,4 jam dan temperatur 40,45,50°C untuk ethanol dan n-hexane, heptana dengan temperatur 50,55 dan 60°C. Kelarutan ethanol terhadap kehilangan berat sangat rendah, pada waktu 2 jam dan temperatur 40°C mempunyai kehilangan berat terendah 0,269% dengan kehilangan berat tertinggi pada waktu 4 jam dan temperatur 50°C dengan kehilangan berat 0,86%. Kelarutan n-hexane terhadap kehilangan berat, pada waktu 3 jam dan temperatur 40°C mempunyai kehilangan berat terendah 2,094% dengan kehilangan berat tertinggi pada waktu 4 jam dan temperatur 50°C dengan kehilangan berat 2,284%. Kelarutan heptana terhadap kehilangan berat tertinggi dibandingkan dengan ethannol dan n-hexane, pada waktu 3 jam dan temperatur 50°C mempunyai kehilangan berat terendah 1,703% dengan kehilangan berat tertinggi pada waktu 4 jam dan temperatur 60°C dengan kehilangan berat 4,884%. Kondisi feedstock yang sudah di debinding terlihat masih terdapat sisa-sisa binder selain paraffin wax, keragaman bentuk pada serbuk menjadikan kehomogenan pada feedstock.Kata kunci: Solvent Debinding, Ethanol,N-Hexane,Heptana

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan unsur carbon (C) terhadap struktur mikro dan sifat mekanik baja mangan. Baja mangan dengan kandungan mangan (Mn) sebesar 14%, divariasikan jumlah carbon mulai dari 0.4% hingga 1.6%. Seluruh sampel dianalisa struktur mikro, lalu diuji sifat mekaniknya meliputi kekerasan, ketahanan aus, ketahanan impak dan kekuatan tarik. Kekerasan rata rata seluruh sampel tidak mengalami perubahan yang signifikan, yaitu 24 HRC, dengan kekerasan rata rata fasa austenit 34 HRC, dan fasa karbida 52 HRC. Hasil pengujian ketahanan aus memperlihatkan bahwa dengan meningkatnya kadar carbon maka ketahanan aus akan semakin meningkat, persentase kehilangan berat terkecil pada kandungan carbon 1,6% sebesar 0,01%. Kekuatan impak dan elongasi meningkat pada kadar carbon 0,4% hingga 1 %, dan menurun pada 1,4% hingga 1,6%. Kekuatan impak paling tinggi yaitu pada kadar carbon 0,7% dan 1% sebesar 187 joule dan 167 joule dengan elongasi 37,7% dan 38,2%. Kekuatan tarik meningkat dengan meningkatnya kadar carbon dari 0,4 % - 1%, namun kekuatan tarik menurun ketika kandungan carbon lebih dari 1%. Baja mangan dengan kadar carbon antara 0,7 % hingga 1 % memiliki kombinasi kekuatan impak, elongasi dan kekuatan tarik yang tinggi. Baja mangan dengan kadar carbon 0,7% dan 1% memiliki fasa karbida yang paling sedikit, sehingga ketahanan impak, elongasi dan kekuatan tariknya tinggi.

An experiment was conducted at the research field of the Department of Agricultural Botany, Patuakhali Science and Technology University, Patuakhali under the Agro-ecological zone-13 (AEZ-13) during the period from November 2012 to February 2013. The aim of the study was to identify the most effective irrigation level for obtaining the better growth and higher yield performance of BARI Gom-25 that are suitable to cultivate under coastal region of Patuakhali, Bangladesh. So, the present study was consists of five irrigations levels including control viz. control or no irrigation (T0), one irrigation at 25 DAS (T1), two irrigations at 25 and 40 DAS (T2), three irrigations at 25, 40 and 55 DAS (T3) and four irrigations at 25, 40, 55 and 70 DAS (T4). The seeds of BARI Gom-25 were collected from the BARI, Joydebpur, Gazipur on 22 November, 2012. The experiment was laid out in completely randomized block design (RCBD) with four replications and analysis was done by the MSTAT-C package program where means were separated by DMRT at 5% level of probability. Data were recorded on various growth and yield attributing traits. The plot size was 5 m2 (2.5 × 2.0 m) where row to row and seed to seed distances were 20 and 10 cm respectively. Data were collected on various morpho-physiological growth, yield and yield attributing traits. Results obtained from the present study, whole characters of the study were significant at 5% by the moisture (irrigation) levels where three irrigations given at 25, 40 and 55 DAS had most effective than that of other moisture levels and no irrigation. From the results investigation, it was found that the tallest plant (76.86 cm), maximum requiring days to anthesis (61.00 days), maturity (109.0 days) and maximum number of effective tillers (5.00 hill-1),the highest grain growth (3.11g at 36 DAA) and grains (44.00 spike-1) were obtained with three irrigation (T3) levels. Similarly, T3 further showed the greater performance on spike length (17.28 cm), 1000-seed weight (50.16 g), grain (4.16 t ha-1), straw (5.89 t ha-1) and biological yield (10.05 t ha-1) as well as the higher harvest index (41.39%). Investigated above whole characters were produced lower performances under no moisture (irrigation) treatments. These results indicated that irrigation at three times (T3) would be most advantageous irrigation levels for wheat production under the studied non saline ecosystem of coastal region.Progressive Agriculture 29 (2): 99-106, 2018

An experiment was carried out at the agronomy field laboratory of Bangladesh Agricultural University, Mymensingh to evaluate the effect of variety and phosphorus on the yield and yield components of groundnut. The experiment comprising of two groundnut varieties viz. BARI Cheenabadam-8 and BINA Cheenabadam-6 and four levels of phosphorus viz. 0, 20, 40 and 60 kg P ha-1. The experiment was laid out in a randomized complete block design with three replications. The highest value of all the parameters e.g. leaf area index (2.02), dry matter (51.88 g plant-1), number of primary branches plant-1 (10.70), number of secondary branches plant-1 (13.85), number of pegs plant-1 (64.35), number of total pods plant-1 (44.50), weight of 100-pods (94.66 g), weight of 100-seeds (44.47 g), shelling percentage (81.84%), seed yield (2.48 t ha-1), pod yield (3.03 t ha-1), stover yield (6.92 t ha-1) and harvest index (30.45%) were recorded from BARI Cheenabadam-8 applied with 60 kg P ha-1. The lowest value of all these parameters was found in BINA Cheenabadam-6 and with no applied phosphorus. It can be concluded that BARI Cheenabadam-8 should preferably be fertilized with 60 kg P ha-1 to obtain the highest yield.Progressive Agriculture 29 (2): 117-126, 2018

Published: September 2018

The study was conducted on 244 crossbred cows of (Central Cattle Breeding and Diry Farm), Savar, Dhaka to evaluate the effect of different productive groups on their lifetime performance of various productive traits using twenty years data. Data were accumulated from a prescribed data sheet maintained by Central Cattle Breeding Station, Savar, Dhaka. Genetic groups for this experiment were Local Friesian (LF), Local Jersey (LJ), Local Hariana X Friesian (LH x F), Local Friesian X Local Friesian (LF x LF) and Local Jersey X Local Jersey (LJ x LJ). The studied parameters were age at puberty, lactation length, lactation yield, total milking days, and total milk yield in lifetime. The data were analyzed using Least-Squares Mixed Model and Maximum Likelihood Computer Program (Harvey, 1990). Analysis showed that genetic groups had a significant effect on age at puberty, lactation length and lactation yield (P<0.01), total milking days and milk yield in lifetime (P<0.001). From the result it was found that earliest age at puberty were in L x F (749.27±99.01). Lactation length and standardized lactation yield were also higher in L x F (258.69±20.04 days and 1408.80±83.60 kg respectively). Total milking days and milk yield were observed higher in (LH x F) with mean of 1468.30±198.58 days and 7340.32±1813.28 kg, respectively. The repeatability estimates of lactation length for genetic groups LF, LJ, LH x F, LF x LF and LJ x LJ were 0.24±0.09, 0.04(-ve), 0.10±0.05, 0.07±0.05 and 0.49±0.22, respectively. The same for lactation yield was 0.17±0.08, 0.27± 0.02, 0.07±0.04, 0.17±0.08 and 0.03±0.05 respectively. From analysis it was revealed that in respect of productive performances the L x F genetic group was found superior compared to other groups but interns of total lifetime productivity, LH x F ranked the highest in the given environment. It is concluded that lifetime productivity needs to be considered as an appropriate guideline for selecting genetic groups for future productivity.Progressive Agriculture 29 (2): 168-177, 2018
Electron properties of topological insulators. The structure of edge states and photogalvanic effects
Authors: Tarasenko S A 
Published: September 2018

Abstract
Integrating the ideas of topology and topological transitions into solid-state physics has led to the theoretical prediction and subsequent experimental discovery of topological insulators, a new class of three- or quasi-two-dimensional dielectric crystalline systems exhibiting stable conducting surface states. This paper briefly reviews the electronic properties of topological insulators. The structure of edge and bulk electronic states in two- and three-dimensional HgTe-based topological insulators is described in particular detail. Recent theoretical and experimental results on the interaction of an electromagnetic field with topological insulators and on edge and surface photogalvanic effects are presented.

The older alluvial surface, consisting on quartzit pebbles, and situated on the height level of the Valensole tableland in conformity with the pliocene top, is an early quaternary formation. Pebbles tools have been discovered on ground level.
The other terraces below can be respectivly attribuated to the Giinz, Mindel, Riss and Wurm glaciations.
Le Danien (Dano-Montien) des Petites Pyrénées et du Plantaurel : étude pétrographique et paléogéographique des faciès "lacustres"
Authors: Freytet Pierre 
Published: September 2018

Dans les Petites Pyrénées et le Plantaurel, on a rapporté depuis longtemps au Danien une formation calcaire lacustre à l'E de la Garonne et marine à l'O (schématiquement). Une étude détaillée de la pétrographie des calcaires "lacustres" montre une grande variété de faciès, certains étant effectivement lacustres, avec figures de remaniement (calcaires graveleux, grumeleux, bréchiques, "varvés", etc.), et d'autres portant des traces d'émersion (fissures) et de pédogènèse (nodules) (faciès palustres).
En y adjoignant les résultats obtenus dans les Corbières, on peut obtenir une reconstitution paléogéographique allant de St Gaudens à Narbonne, soit plus de 200 km. D'Ouest en Est, on peut identifier un domaine marin franc (0 de la Garonne), dans un domaine marin à la base puis lacustre-palustre (E de la Garonne), un domaine seulement lacustre et palustre (Plantaurel), et un domaine complexe, palustre, ou fluviatile, ou mixte lacustre-palustre (Corbières).
Les Giraffidae (Artiodactyla, Mammalia) du Miocène de Béni Mellal, Maroc
Authors: Heintz Emile 
Published: September 2018

The study of new material from Beni Mellal has established the existence in this locality of a new giraffid : Palaeotragus lavocati n.sp. Certain specimens grouped under the heading of Palaeotragus sp. could indicate the presence of a second species, of smaller size and with more primitive characters.
P. lavocati is more closely related to Palaeotragus tunguren-sis from Mongolia than to other species of the same genus. The affinities between P. lavocati and P. primaevus from Kenya cannot be established with precision due to the lack of an adequate iconography. Palaeotragus from Beni Mellal indicates an ante-Vallesian age, situated in the upper part of the middle Miocene. The locality of Beni Mellal shows, like other African and Eurasiatic localities, that the Hipparion fauna is preceded by a palaeo-tragine fauna.
Formations quaternaires glaciaires fluviatiles et colluviales en Corse Orientale. Sédimentologie, stratigraphie et tectonique
Authors: Conchon Odette 
Published: September 2018

Le Quaternaire de l'intérieur de la Corse a été étudié sous de multiples aspects : situation des divers dépôts (glaciaires, fluviatiles, colluviaux) et sédimentologie (disposition, mor-phométrie, granulométrie, lithologie et altération des galets, granulométrie, morphoscopie et minéralogie des matrices), relations entre ces dépôts et les sédiments marins, néotectonique, paléoclimats, La chronologie relative est basée sur les relations topographiques entre alluvions, et surtout sur leur degré d'altération (sols et paléosols, galets, matrices). Possible seulement pour des sédiments récents de haute montagne et quelques gisements marins, la radiochronométrie permet de synchroniser les alluvions glaciaires et fluviatiles récentes avec celles du Quaternaire alpin. L'intensité et le type d'altération des galets suggèrent des comparaisons entre les alluvions anciennes de Corse et les formations des Pyrénées étudiées sous le même angle par M. Icole (1973).
La tectonique quaternaire en Corse a été replacée dans son contexte de Méditerranée occidentale.
