Authors: He Jian , Ding Wen Feng , Wang Yan , Liu Zhi Wu
Published: August 2013

Cu-Sn-Ti filler alloy was applied as brazing material to join UcBN grains onto the steel matrix using three different brazing temperatures (880, 900 and 920°C). The microstructure and properties of the UcBN-filler-steel joint and the compressive strength of UcBN grains were investigated respectively by means of scanning electron microscopy and energy dispersive X-ray spectroscopy and compressive test. The microstructural studies revealed an intermetallic interlayer of type TiN, TiB and TiB2 at the joint interface, which grew with increasing brazing temperatures. The compressive force of UcBN grains with a maximum value of 79.3N was found when the brazing temperature was 900°C for 8 min. The wear process of brazed UcBN grains was a process transforming from abrasion wear to micro fracture mutually.

Authors: An Wei Guang , Xiao Hua Hua , Sun Jin Hua , Yan Wei Gang , Zhou Yang , Huang Xin Jie , Wang Hui , Jiang Lin
Published: August 2013

To study downward flame spread across XPS surface, a series of laboratory-scale experiments were conducted. Typical flame spread characteristics were obtained. The flame spread process comprises four stages. There are twice accelerations during flame spread. The influence of maximum flame height on flame spread rate is not significant. The predicted flame spread rate utilizing mass loss rate is lower than the measured value. Three stages: increasing stage, stable stage and decreasing stage are observed in both change of maximum flame height and flame area. The changing trend of mass loss rate is similar to that of maximum flame height. For stage 1 and stage 3, exponential change of mass loss rate with time is found. The mass loss rate is constant for stage 2. The heat flux to the preheating zone is higher than that to surrounding environment. Experimental results agree well with theoretical analysis.

Authors: Lee Kang Min , Oh Keun Yeong , Chen Liu Yi , Li Rui
Published: August 2013

This paper experimentally presents the effects of different bolted connection types on the seismic performance of column-tree steel moment connections used in moment resisting frames. Two full scale test specimens were fabricated and tested: one specimen with slip critical bolted beam splices and the other one with bearing type bolted beam splices. The bearing type splice specimen was expected an improved deformation capacity by means of bolt slippage. The experimental results showed that the slip critical splice specimen successfully developed ductile behavior without brittle fracture until 5% story drift ratio, however for the bearing type splice specimen, the beam bottom flange fractured at 4.0% story drift ratio due to stress concentration around the weld access hole area. However the energy dissipation capacity of the bearing type splice specimen was better than that of the slip critical splice specimen until 4.0% story drift ratio.
Alternative Binder for Fibercement Building Materials
Authors: Gomes Carlos Eduardo Marmorato
Published: August 2013

This paper shows results of some properties of Magnesium oxysulfates (MOS) reinforced by fibers, specially the modulus of rupture (MOR) and durability. As showed by the literature [7], It is known that MOS cement can be formulated by the reaction between magnesium oxide and magnesium sulfate solution and like that of magnesium oxychloride (MOC) has very good binding properties. The resistance of MOS cements to abrasion is about 1.5 times that of Portland cement, but only 50% that of MOC cement. Its compressive and transverse strengths are superior to Portland cement but not as good as MOC cement. In this way, the authors formulated different matrices of MOS cement reinforced by polymeric and cellulose fibers. Also, calcium carbonate was employed. The results showed to be possible the use of MOS fibercements as an alternative for non-asbestos products such as panels and roofing elements besides the effective reduction of CO2 emission to atmosphere.

Published: August 2013

In the time of low-permeability sandstone reservoir explored, effective stress rise gradually, stress sensitivity has happened, which cause permeability decline. Allowing to initial geostress, the study on Jilin oilfield Fuxin326 oil layer and made the rock core experiment are presented. The experimental results show that the stress sensitivity of this oil layer is small the regularity of permeability changes is in accordance with exponential function. The stress sensitivity of high permeability core is larger than low permeability. Moreover, experiments and theoretical analysis shows that low permeability core has a smaller permeability loss than high permeability core in load and unload process. Loading and unloading process leads to elastic plastic deformation of rocks, and it is the major reason which permeability can not return completely.
New Scheme to Resist Seismic Collapse of RC Frame
Authors: Li Zhi Ping , Hao Jin Xin
Published: August 2013

Earthquake would cause unacceptable damage in reinforced concrete structures. In this paper, two retrofitting methods based on alternative load path are proposed for the reinforced concrete structure. One method is to add steel braces to the structure, and another one is to add tension cables to the structure. Pushover analyses for all frames are carried out using SAP2000. From the analysis results, steel braces or tension cables delay the formation of the first plastic hinge and failure of columns, and can better improve the seismic performance of reinforced concrete frame. The research results can be utilized for displacement-based seismic design and seismic performance evaluation of RC structures.
Corrosion Characteristics of Reinforced Steel Bar Emedded in Mortar Specimen(W/C:0.4) Aged 5 Years in Seawater
Authors: Moon Kyung Man , Won Jong Pil , Park Dong Hyun , Lee Myeong Hoon , Kim Yun Hae
Published: August 2013

Reinforced concrete structures have been increasingly widely used in numerous industrial fields. These structures are often exposed to severely corrosive environments such as sea water, contaminated water, acid rain, and the seashore. Thus, corrosion problems of the steel bars embedded in concrete are very important from a safety and economic point of view. In this study, the effects of cover thickness on the corrosion properties of reinforced steel bar embedded in mortar specimen were investigated using electrochemical methods such as corrosion potentials, polarization curves, cyclic voltammograms, galvanostat and potentiostat. Corrosion potentials shifted in the noble direction, and the value of AC impedance also exhibited a higher value with decreasing cover thickness, furthermore, polarization resistance also increased with decreasing cover thickness. This is probably that the thinner cover thickness, it is easy for the dissolved oxygen and chloride ion to intrude and diffuse to the steel bar, thereby making it easier to corrode on the steel surface compared to thicker cover thickness, which is resulted in forming the corrosive products on the steel surface. Therefore, it is considered that the corrosive products plays a role to provide nobler value of corrosion potential and higher value of impedance. Consequently, it seems that the corrosion resistance of inner steel bar may depend on mainly not cover thickness but the resistance polarization due to corrosive products in the case of immerged for 5 years in this experiment.

Published: August 2013

The compression deformation processes of powder particles were investigated by the way of mesoscopic simulation based on finite element method of discrete body. The strain process of the particles in typical position, the deformation difference of the particles in different positions and the strain status of particles were investigated under various compacting pressure. The results show that the deformation process of the compressed powder particles consisted of three stages, which were the initial stage of small deformation, the major stage of the sharply changes of strain and the ultimate stage of strain tending to stable state. The interface friction has a significant influence on the deformation and pressed density of particles close to die wall. The density can not be increased with the increase of compacting pressure of compaction infinitely.
The politics of rape: Traces of radical feminism in Disgrace by J. M. Coetzee
Authors: Barnard Lianne
Published: August 2013

Disgrace can be read as a deliberation on rape in all its complexity, articulating and commenting upon many of the positions typical of the radical feminism of the seventies. Some feminists classify prostitution as a form of rape. Prostitution is the ideal form of sex for the main character, David, because it allows him to fantasize that a woman mirrors his wishes. The border between rape and consensual sex is shown to be problematic in the relationship between David and his young student, Melanie. Although some readers find that Melanie was willingly seduced, others consider that she was raped. The charge of sexual harassment is therefore unsatisfactory for both sides and, since David refuses to read the charges brought against him, he effectively silences his accuser. When his daughter, Lucy, equates heterosexual sex with killing and hating women, one can read it as evoking the radical feminist idea that men as a class subordinate women as a class through the threat of rape. Lucy’s political lesbianism is a logical response to such misogyny. After being rape, Lucy accepts a subordinate position and this proves the power of rape in controlling women. Like one of the Sabine women, Lucy seems willing to sacrifice herself for peace between black and white in South Africa.

Abstract. Long-term monitoring of the chemical composition of clouds (73 cloud events representing 199 individual samples) sampled at the puy de Dôme (pdD) station (France) was performed between 2001 and 2011. Physico-chemical parameters, as well as the concentrations of the major organic and inorganic constituents, were measured and analyzed by multi-component statistical analysis. Along with the corresponding back-trajectory plots, this allowed distinguishing four different categories of air masses reaching the summit of the pdD: polluted, continental, marine and highly marine. This statistical tool leads to the determination of criteria (concentration of inorganic compounds, pH) that differentiate each categories of air masses. Highly marine clouds exhibited high concentrations of Na+ and Cl−; the marine category presented lower concentration of ions but more elevated pH. Finally, the two remaining clusters were classified as "continental" and "polluted" with increasing concentrations of NH4+, NO3−, SO42−. This unique dataset of cloud chemical composition is then discussed as a function of this classification; this will allow the creation of "standard chemical scenarios" that can serve for modeling purposes on multiphase cloud chemistry.
Analysis of the ground vibration produced by debris flows and other torrential processes at the Rebaixader monitoring site (Central Pyrenees, Spain)
Authors: Abancó C. , Hürlimann M. , Moya J.
Published: August 2013

Abstract. The use of ground vibration sensors for debris-flow monitoring has increased in the last two decades. However, the correct interpretation of the seismic signals produced by debris flows still presents many uncertainties. In the Rebaixader monitoring site (Central Pyrenees, Spain) two different ground vibration stations with different characteristics in terms of recording systems and site-specific factors have been compared. The shape of the time series has been recognised as one of the key parameters to identify events and to distinguish between different types of torrential processes. The results show that the site-specific factors strongly influence on the ground vibration registered at each geophone. The attenuation of the signal with the distance has been identified as linear to exponential. In addition, the assembly of the geophones to the terrain also has an important effect on the amplification of the signal. All these results highlight that the definition of ground vibration thresholds for debris-flow detection or warning purposes is a difficult task which is clearly influenced by site-specific conditions of the geophones.

Authors: Suana I Wayan , Haryanto Hery
Published: August 2013

Sanurus sp., Acrocercops sp. dan Helopeltis sp. merupakan hama-hama penting tanaman jambu mete yang dilaporkan di Nusa Tenggara Barat. Penggunaan pestisida untuk mengendalikan hamahama tersebut ternyata kurang berhasil sehingga dicari alternatif, yaitu dengan menggunakan musuh alami. Laba-laba merupakan salah satu musuh alami yang ditemukan di perkebunan jambu mete. Tujuan penelitian ini adalah untuk mengetahui keanekaragaman dan potensi pemangsaan laba-laba di perkebunan jambu mete. Penelitian dilakukan di Dusun Jugil, Desa Sambik Bangkol, Lombok Utara. Pemangsaan laba-laba diamati secara langsung selama 78 hari, mulai bulan Mei sampai Agustus 2009. Formula Edgar digunakan untuk mengetahui pemangsaan laba-laba per hari. Hasil penelitian menemukan 19 spesies dari delapan famili laba-laba. Kelimpahan Neoscona theisi lebih tinggi daripada Tetragnatha maxillosa, tetapi proporsi N. theisi dengan mangsa lebih rendah daripada T. maxillosa, sehingga kemelimpahan laba-laba pada pertanaman jambu mete belum tentu menunjukkan potensinya sebagai musuh alami. N. nautica memangsa lebih banyak dibandingkan dengan N. theisi, yaitu berturut-turut 3,84 dan 1,67 mangsa per hari. Tidak semua mangsa N. nautica merupakan hama tanaman jambu mete, sebaliknya semua mangsa N. theisi merupakan hama tanaman jambu mete. Hal ini menunjukkan bahwa, jumlah mangsa yang dimangsa laba-laba per hari tidak secara langsung menunjukkan potensinya sebagai musuh alami.

Crocidolomia pavonana merupakan hama penting pada tanaman sayuran Brassicaceae. Insektisida nabati merupakan salah satu alternatif potensial untuk mengendalikan hama tersebut. Penelitian ini bertujuan menentukan tingkat toksisitas ekstrak etil asetat buah Piper aduncum (EtPa), ekstrak metanol buah Sapindus rarak (MeSr), ekstrak air buah S. rarak (AqSr), serta campuran ekstrak EtPa + MeSr dan ekstrak EtPa + AqSr terhadap larva C. pavonana. Setiap ekstrak diuji terhadap larva instar II C. pavonana dengan metode celup daun. Pada taraf LC95 - 72 jam setelah perlakuan (JSP), ekstrak EtPa lebih beracun terhadap larva C. pavonana daripada ekstrak MeSr dan AqSr, masing-masing sebesar 14,5 dan 12,8 kali. Pada taraf LC95, campuran ekstrak EtPa + MeSr (1 : 10, w/w) sekitar 1,64 kali lebih beracun terhadap larva C. pavonana daripada campuran ekstrak EtPa + AqSr (1 : 10, w/w). Berdasarkan indeks kombinasi pada pengamatan 48, 72, dan 96 JSP, campuran ekstrak EtPa + MeSr pada taraf LC50 serta campuran ekstrak EtPa + AqSr pada taraf LC50 dan LC95 bersifat aditif, sedangkan campuran ekstrak EtPa + MeSr pada taraf LC95 bersifat sinergistik lemah. Selain mengakibatkan kematian, perlakuan dengan semua ekstrak uji juga menghambat perkembangan larva C. pavonana dari instar II ke instar IV. Dengan demikian, ekstrak EtPa, MeSr, AqSr, serta campuran ekstrak EtPa dan S. rarak berpotensi untuk digunakan sebagai salah satu alternatif dalam pengendalian hama C. pavonana.

Published: August 2013

Asymmetric supercapacitors with high energy density are fabricated using a self‐assembled reduced graphene oxide (RGO)/MnO2 (GrMnO2) composite as a positive electrode and a RGO/MoO3 (GrMoO3) composite as a negative electrode in safe aqueous Na2SO4 electrolyte. The operation voltage is maximized by choosing two metal oxides with the largest work function difference. Because of the synergistic effects of highly conductive graphene and highly pseudocapacitive metal oxides, the hybrid nanostructure electrodes exhibit better charge transport and cycling stability. The operation voltage is expanded to 2.0 V in spite of the use of aqueous electrolyte, revealing a high energy density of 42.6 Wh kg−1 at a power density of 276 W kg−1 and a maximum specific capacitance of 307 F g−1, consequently giving rise to an excellent Ragone plot. In addition, the GrMnO2//GrMoO3 supercapacitor exhibits improved capacitance with cycling up to 1000 cycles, which is explained by the development of micropore structures during the repetition of ion transfer. This strategy for the choice of metal oxides provides a promising route for next‐generation supercapacitors with high energy and high power densities.

Published: August 2013

Venetian physician Giovanni Domenico Santorini is revered as one of the most industrious and thorough anatomists of the eighteenth century. After receiving his medical degree in Pisa, Santorini worked as a physician and professor of anatomy and obstetrics in Venice. Of interest, he was a student of Malpighi while in Pisa. He quickly established himself as a dynamic lecturer and meticulous dissector. Santorini's anatomical observations include the prostatic venous plexus, accessory pancreatic duct, corniculate cartilage, parietal emissary veins, the risorius muscle, and many other structures. In addition to the detailed descriptions of these structures, he also produced copper plates and illustrations that are revered as “masterpieces” of that era. Santorini publishedObservationes anatomicae(Anatomical observations) in 1724, however his primary work, which included the description and anatomical drawings of the accessory pancreatic duct, was not published until thirty‐eight years after his death. This posthumous release ofJo. Dominici Santorini anatomici summi septedecim tabulae[Giovanni Domenici Santorini, the excellent anatomist's seventeen drawings] was accomplished by Giambattista Morgagni and his disciple, Michael Girardi in 1775. Giovanni Santorini's assiduous dissections have significantly enhanced our knowledge of human anatomy and his work has been immortalized with several anatomical eponyms. Clin.
