Published: September 2018

Mesin pemanen kombinasi untuk padi dimodifikasi untuk memanen jagung. Agar jagung bisa dipanen dengan mesin tersebut maka diperlukan penyesuaian pada beberapa bagian, salah satunya sistem pembersihan mesin pemanen kombinasi. Hal ini disebabkan oleh perbedaan lahan, pohon, dan buah dari padi dan jagung. Penelitian ini bertujuan untuk meningkatkan kebersihan bulir jagung yang telah terpipil dan membuang sampah yang masuk ke dalam ruang penyaringan sehingga diperoleh pembersihan yang optimal serta mengurangi jagung yang terbuang. Metode penelitian menggunakan reverse engineering dengan mengidentifikasi fungsi dari bagian-bagian sistem pembersihan mesin pemanen kombinasi. Pengujian dilakukan di laboratorium dengan kondisi lantai rata dan datar. Pengujian meliputi kadar air jagung, bentuk dan posisi sieve, lebar celah pembuangan, kemiringan penampung jagung, serta pengaruh putaran engine dan kecepatan angin dari blower. Hasil pengujian menunjukkan bahwa kadar air jagung 19% menghasilkan jagung pipilan yang bersih. Agar biji jagung dapat bergerak ke area screw pembawa, perlu kemiringan penampung jagung minimal sebesar 20°. Celah pembuangan sampah dibuat sebesar 65 mm supaya sampah tidak tersumbat pada saat pembersihan butir jagung. Posisi dan bentuk sieve juga berpengaruh terhadap jumlah jagung yang terbuang dan proses penyaringan. Sieve yang dipasang dengan kemiringan 20° berhasil mengurangi jagung yang terbuang menjadi 4,67% pada putaran engine 1500,2 rpm dan kecepatan angin dari blower sebesar 1,7 – 3,9 m/s.

Mining accidents,
considered as technological disasters, are global problems as well as usually
common issues faced by developing countries. These accidents cause considerable
number of deaths, injuries and economic losses worldwide. The statistics show that
mining accidents occurred mostly in the coal mines in Turkey and also in the
world. This is the fact that, in the period of 2010-2015 in Turkey, coal mining
accidents caused approximately 81% of human casualties in the mining accidents.

Firedamp explosion,
fire, carbon monoxide poisoning, inundation and collapsing of mine stopes are
the most common causes of coal mining accidents in Turkey. Only in 2014, 301
miners died because of mine fire in the Soma-Eynez underground coal mine and 18
miners also died because of inundation in the Karaman-Ermenek underground coal
mine.

In order to prevent/
mitigate deaths, injuries and economic losses caused by mining accidents, the
primarily step is risk reduction studies because mining accidents are based on
generally preventable issues like infrastructure, technology and management
problems. A successful risk reduction plan for mining accidents requires
analyzing and commenting the factors causing mining accidents in the best way.
This risk approach will allow us to eliminate many mining accidents or overcome
them with the least damage. Some risk reduction studies have conducted for
prevention of mining accidents or reduction of the losses. Actually, there were
serious gaps in the laws about occupational health and safety of workers in
mining sector until 2012. The significant amendments were made to the
regulations with the Act No. 6331 that came into force in 2012. Some amendments
were also made to relevant regulations in 2014. However, the painful experiences
show that the implementing and monitoring of existing regulations and
amendments are insufficient. In that regard, taking and monitoring essential
measures against work accidents caused by the human factor must be the primary
task for mining activities.

In this study, risk reduction studies are discussed with evaluating of
the coal mining accidents which occurred in Turkey.

Investigating of dielectric anisotropy and birefringence of binary liquid crystal mixtures
Authors: ÖZĞAN Şükrü 
Published: September 2018

Absorbance,
capacitance, conductance, dielectric anisotropy and birefringence properties
and splay elastic coefficient of 4’-Hexyl-4-biphenylcarbonitrile (6CB) and its
mixture with 4’-Octyl-4-biphenylcarbonitrile (8CB) were investigated. The
absorbance was studied using the UV-visible spectrophotometry.
Capacitance, conduction and dielectric
measurements for 6CB and its mixture were performed in 0-1000
kHz frequency range at the room temperature. Capacitance-voltage and capacitance-frequency
changes were investigated for the mixture. Threshold voltage was determined as 2.1 V. It was
seen that the capacitance suddenly damped at this voltage. Capacitance is large at lower frequencies
and small at higher frequencies than 100 kHz. The conductance-voltage change was obtained for the mixture. The conduction suddenly rose at the threshold voltage. The conduction is small at lower frequencies and large at higher
frequencies. Dielectric, birefringence index and splay elastic constant were investigated
for 6CB/8CB mixture. The measured values of the mixture are bigger than 6CB
values up to the certain frequency.
Effect of nanoparticles on mechanical and tribological properties of composite friction materials
Authors: Yusubov Fikrat 
Published: September 2018

Wear
mechanism of newly developed asbestos-free frictional materials (i.e. brake
pads material) was investigated by physical-mechanical experiments. The
suitability of the developed these new
composite materials were investigaed by firiction testes at the different
temperatures. Thermal
investigation was performed by a differential scanning calorimetry (DSC) and
thermogravimetric analysis (TGA). Stability
and mechanical properties at different temperatures of the brake pad materials were
comparatively evaluated. Testing results showed that under the given
conditions, new developed frictional material has the advantages of the good
tribological properties over the widely used commercial asbestos enhanced
material as a FK-24A (Retinax, mark B). The research of the thermal and wear
behaviour of materials indicates that brake pair has better frictional
characteristics and wear resistance performance at high temperature. With
use of new friction brake pads materials will be improved the safety of braking
processes, and the quality in drilling will be increased. There is also an
environmental and economic advantages in using the new asbestos-free materials
in the break pads.

Published: September 2018

A new Schiff base ligand
was synthesized from a reaction of 5-benzoyl-4-hydroxy-2-methyl-6-phenyl-2H-pyridazine-3-one
and 1,3-diaminopropane. Schiff base metal complexes
were synthesized from a reaction of Ni(AcO)2×4H2O, Cu(AcO)2×H2O, Co(AcO)2×4H2O, Pd(AcO)2
metal salts and ligand, respectively.
All compounds were characterized using magnetic susceptibility,
elemental analysis, NMR (for ligand), UV-Vis and FT-IR spectroscopic analysis.
While octahedral structure has been proposed for Ni(II), Pd(II) and Co(II)
complexes, square-planar geometry is suggested for Cu(II) complex. Synthesized
compounds were evaluated for their antioxidant effect, DNA
cleavage and antimicrobial studies. The DPPH free radical scavenging activity
of compounds 1, 2, 3, 4 and 5 on DPPH were found as 38.5%, 32.5%, 36.9%, 35.7%
and 45.7% at 200 mg l-1, respectively. The compounds 4 and 5 revealed maximum
ferrous chelating activity of 64.5% and 78.1% at 200 mg ml-1,
respectively. For all the compounds, DNA cleavage studies showed complete DNA
digestion at 100 mg ml-1. Antimicrobial activities of 3 and 4
complexes against Staphylococcus
aureus (ATTC 6538) were determined to be in 12 mm diameter.
Méthode d'imprégnation des matériaux d'altération argileux en vue de leur étude en lames minces
Authors: Prone André 
Published: September 2018

L'imprégnation des matériaux d'altération argileux nécessite d'adapter la résine fluide aux caractéristiques mécaniques des échantillons, et à leur degré de saturation en eau. L'emploi de résine époxyde modifiée et d'oxyde de propylène miscibles dans H20, autorise une imprégnation sur le terrain sans déshy-dration préalable, ce qui évite toute déformation ultérieure de la structure des argiles.
Une imprégnation susceptible d'envahir les pores les plus fins est ensuite réalisée en laboratoire au moyen d'une cellule à vide.
Cette méthode permet de conserver à tous les matériaux friables, sensibles à l'action de l'eau, leurs structures et mi¬ crostructures.
Le littoral du "Pays de Bizerte". Etude morphologique
Authors: Miossec Alain 
Published: September 2018

Cette étude porte sur la partie nord du littoral de Bizerte peu étudiée jusqu'à présent. Après une première partie où sont décrits les caractères morphologiques du littoral (types de côtes, couverture de dunes), l'essentiel de la seconde partie traite des héritages Quaternaires dans les formes et la stratigraphie du littoral.
Une étude détaillée de coupes permet de montrer que la plate-forme d'abrasion, élément majeur du paysage, date de l'Eutyrrhénien et que l'essentiel du tracé de la côte est en place dès cette époque.
L'étude se termine sur l'analyse de hauts niveaux attribués au Quaternaire ancien, sans que leur origine marine soit pleinement démontrée.
Paléogéographie et répartition des faciès au Cénomanien dans le bassin rhodano-vocontien
Authors: Porthault Bernard 
Published: September 2018

During the Cenomanian times, the paleogeography of the "Rhodano-Vocontian basin" was largely controlled by great faults trending SW-NE and SE-NW, probably inherited from the late Hercynian tectonic activity. These faults played a significant role in the sedimentation.
To the West and to the North, coarse detrital materials were supplied by the "Massif Central" and its sedimentary cover : they were accumulated onto a platform, parted from the Hercynian landmass by the Cévennes faults and their northern tributaries.
In between the Cévennes and Nîmes faults, there was a subsiding through ("sinus rhodanien") where fine-grained terrigenous deposits were accumulated, coming from the next platform. This trough was limited to the South by the "Du-rancian high" and the depending "Ventoux-Lure ridge".
In the central and eastern parts of the basin, the sediments were more definitely pelagic (shales and argillaceous limestones). Slumpings and sudden variations in thickness eventually occur in this area, reflecting the influence of the Hercynian faults.
During most of the Cenomanian time span, the sedimentation was quiet, but epirogenic movements took place in the Middle Cenomanian, causing local coarse detrital influx.

Published: September 2018

A repartition of inoceramus has been established after zonal collecting made in South-eastern France and is compared to the repartition, till now incomplete, of the Paris Basin.
The Inoceramus fauna from South-eastern France shows some differences in composition and in species repartition with German faunas (Troger 1966, 1967). An explanation of this fact as well as the differences existing in the fauna of the Paris Basin is proposed.
Analyse pollinique du remplissage pleistocène inférieur et moyen de la grotte du Vallonnet (Roquebrune — Cap-Martin, Alpe-Maritimes)
Authors: Renault-Miskovsky Josette , Girard M. 
Published: September 2018

Palynologie analysis of lower and middle pleistocene filling of Vallonnet cave, has allowed to show three great climatic stages. Inside bottom of stalagmitic floor and beach deposits, an important wooded shelter determines a hot and wet climate similar to an interglacial climate.
At the level of unconsolidated filling, steppic feature of lands cape seems correspond to cool, but little damp climate of a glacial period.
In the sealing stalagmite, pollens of individualized wooded shelter suggest the return of a temperate hot damp climate, probably contemporaneous with a new interglacial stage.
Occurence of a single exotic taxon (Pterocarya) at the basis of diagram, does not allow to precisely assign the different stages of cave filling in the lower pleistocene chronostratigraphy.
Contributions on evaporite diagenesis
Authors: Ciarapica G. , Passeri Leonsevero 
Published: September 2018

This is a preleminary report about the diagenesis of the Messinian evaporites in Tuscany. Our final purpose is to formulate a general scheme of the diagenetic evolution of Ca-sulfate evaporites through different stages. The main topic is represented by the gypsum -> anhydrite replacements. The comparison between ancient (Triassic) evaporites, where all the gypsum was replaced by anhydrite, and Messinian evaporites, just partially anhydritized, is very usefull for this purpose.
Either early or late diagenesis gives rise to a large number of textural and structural changes in Ca-sulphate evaporites due to the passages of gypsum -> anhydrite -> gypsum. If these replacements take place during the late diagenesis they can produce distortion or total distruction of the primary structures, giving rise to new ones.
Late diagenetic structures are sometimes considered as syndepositional or early diagenetic, so that the result is that the depositional environment coming from this interpretation can be extremely different from the true one.
La faune de Mutilus (Ostracodes : Hemicytheridae) de la région des Zemmours (Maroc Nord-occidental) à la fin du Miocène et au Pliocène
Authors: Ducasse Odette , Cirac Pierre 
Published: September 2018

The genus Mutilus is represented by two polymorphic species in the Mio-Pliocene of Zemmours : M. retiformis (Terquem) and M. venetiensis Uliczny.
These populations are very dependent to environmental variations during the paleogeographic evolution of the region. Their structures are in relation with the variations of the energy of the environment and the thickness of the water layer.
The geographic distribution of populations of Mutilus outside the Zemmours area, in the north-west Morocco, shows the extension and the more or less important development of the phytal zones in the landscape. The structural stade characterized, in the middle Pliocene, by a maximum polymorphism in the two species is the best chronologic marker.
Interprétation paléogéographique d'une tourbe de Torson di Sotto (Lagune de Venise, Italie)
Authors: Pirazzoli Paolo Antonio , Planchais Nadine , Rosset-Moulinier Marie , Thommeret J. 
Published: September 2018

Une carotte prélevée dans la partie centrale de la lagune a rencontré une couche de tourbe située entre -1,3 et -2,0 m par rapport au niveau moyen de la mer. Les pollens montrent une prédominance du Chêne et de l'Aune et témoignent de l'existence d'une phase transgressive entre la base (sédiments d'eau douce, datés 1730 ± 80 BP) et le sommet de la tourbe. Les sédiments saumâtres du sommet, datés 1 140 ± 80 BP, se caractérisent par la diminution de la quantité de pollens et par l'augmentation du pourcentage des halophytes.
D'après l'étude des Foraminifères, cette transgression a été précédée par une phase régressive. La séquence fait apparaître ainsi, de bas en haut : (1) un milieu oligo à mésohalin (entre -3,3 et -2,5 m), avec des Foraminifères très abondants ; (2) un milieu d'eau douce (entre -2,5 et -2,0 m) ; (3) la tourbe de 70 cm d'épaisseur, de plus en plus saumâtre ; (4) un milieu mésohalin (au-dessus de -1,3 m).
Des corrélations avec les localités voisines montrent que des phénomènes analogues se sont produits, à la même époque, dans une zone littorale relativement vaste.
Cette oscillation régression-transgression est attribuée à une augmentation de la pluviosité, vers la fin de l'époque Romaine, augmentation qui aurait changé le cours de plusieurs rivières et modifié ainsi, temporairement, l'équilibre hydrologique de cette région marécageuse.
Depuis environ un siècle, les travaux effectués par l'homme rendent ici la transgression de plus en plus rapide. Les barênes, démantelées par l'érosion, sont en voie de disparition, remplacées par de vastes bassins d'eau.
L'hydrogéologie de la partie occidentale de la dépression permienne bordant à l'Ouest le Massif des Maures (Bassin de Cuers)
Authors: Travi Yves 
Published: September 2018

Après un bref rappel de la lithostratigraphie, de la tectonique et de la géomorphologie de la dépression de Cuers et de ses bordures, on essaye de dégager les grands traits de l'hydrogéologie régionale. On caractérise les différents aquifères et on précise les mécanismes hydrogéologiques régissant les communications variées qui peuvent exister entre les réservoirs. Il apparaît ainsi, essentiellement, que le Permien peut jouer un rôle intéressant et que les nombreuses communications sont dues à une grande variété lithologique, à la tectonique et à la présence d'un recouvrement quaternaire relativement étendu.
L'origine de certaines anomalies constatées antérieurement dans le chimisme des eaux (fortes concentrations locales en sulfates) a pu être précisée et mise en relation avec les accidents du secteur concerné.
Enfin, un bilan approximatif a été établi, qui fait ressortir l'existence d'un déficit d'écoulement très probablement lié à des fuites se produisant en profondeur au niveau des aquifères du Permien inférieur.
Les relations plate-forme-bassin-continent dans le Bathonien de Provence
Authors: Arnaud Michel , Monleau Claude , Moulan Guy 
Published: September 2018

In the middle and upper Bathonian of the Cuers area, the sedimentation in the basin is stopped for the first time, with setting of oolitic to sandy dunes, the origin of which in an eastern carbonate platform, now eroded. Then, the deposition of limestones and marly limestones will be dominate by the dunal topography and by the interference of a fault (S.S.W. to N.N.E.) which limits the basin and platform zones. At the beginning of the Callovian time, the topography is flattened and the lack of tectonical events indu¬ ces the removal of the basin realm towards the West.
During the continental uplift (eastern and southeastern parts of the region), clastic material is brought into the basin and the Carbonate platform. First, the translation begins in the North (lower Bathonian) then in the South (middle Bathonian). Quartz grains, studied with the Stereoscan reveals two areas for the origin of these deposits : one with rhyolitic quartz (Brignoles-Cuers) where the high ratio of automorphic grains is probably due from the Corsica region, the other with granitic-metamorphic grains (Bandol) with opportunity of Sardinia. The pedogenetic features on these grains show that during the Jurassic, all requirements were statisfied for the genesis of a ground on rhyolitic outflows, with a possibility of an evolution into bauxite.
Les formations dolomitiques du Jurassique supérieur en basse Provence : l'exemple du Massif de l'Etoile, au Nord de Marseille

Published: September 2018

Description de la puissante série carbonatée de l'aire centrale du massif de l'Etoile (Marseille), du Kimmeridgien moyen au Berria-sien. La séquence montre une tendance à l'émersion entrecoupée de rythmes infratidaux-intertidaux-supratidaux. Trois modalités ont été mises en évidence dans les phénomènes de la dolomitisation : zone externe de la plate-forme, zones internes abritées, puis confinées (dolsparites, dolmicrites, dolomies laminées et horizons sapro-péliens) en fonction des porosités primaires.
Des silicifications liées aux eaux météoriques, en régime intertidal-supratidal, établissent des horizons cherteux formant un barrage aux processus de la dolomitisation.
Introduction générale à l'étude des marais salants de Salin-de-Giraud (Sud de la France). Le cadre géographique et le milieu
Authors: Perthuisot Jean-Pierre 
Published: September 2018

L'implantation et l'extension d'un salin à l'extrême sud de la Camargue ont été favorisées par la présence de marais et d'étangs et une balance hydrique largement déficitaire, surtout en été. C'est pourquoi le Salin de Giraud est alimenté en eau de mer d'avril à septembre : au cours de cette période, les eaux suivent des cheminements bien déterminés et se concentrent progressivement de sorte qu'un champ de salinités stable (35 -300 %o) couvre l'ensemble des surfaces évaporatoires. Après chaque moisson, les saumures restant sur le salin sont stockées ou évacuées selon leur concentration.
Les peuplements animaux et végétaux s'organisent en fonction du confinement progressif des eaux. Les premiers bassins supportent des populations de type lagunaire auxquelles succèdent des associations spécialisées dans la zone hypersalée.
Aux variations de la chimie des eaux et des peuplements biologiques correspond une organisation longitudinale des faciès sédimentaires et l'on peut définir une succession horizontale de 5 types de faciès depuis les détritiques jusqu'aux dépôts de sel. Localement la sédimentation peut subir des variations en fonction de la bathymétrie, de l'exposition au vent, etc.
En définitive, le dispositif sédimentaire que constitue un salin s'apparente à certains bassins évaporitiques naturels actuels ou fossiles.
