Microscopic Properties of Hydrogen Peroxide Activated Crumb Rubber and Its Influence on the Rheological Properties of Crumb Rubber Modified Asphalt
Authors: Li Bo , Li Hao , Wei Yongzheng , Zhang Xingjun , Wei Dingbang , Li Jia
Published: May 2019

Crumb rubber modified (CRM) asphalt binder has been affirmed to improve resistance to rutting, moisture susceptibility, low-temperature cracking, and asphalt durability. However, CRM has poor compatibility with asphalt since crumb rubber molecules are vulcanized. The objective of this study was to develop a new method to prepare activated crumb rubber using hydrogen peroxide (H2O2) solution and to explore the rheological properties of H2O2 activated CRM (ACRM) asphalt. Three different percentages of H2O2 solution were used to activate crumb rubber. The surface properties of oxidized rubber were analysed using scanning electron microscopy. Moreover, the pore structure in rubber powder was investigated. The rheological properties of bitumen samples obtained from treated and untreated rubber were characterized by conducting dynamic shear rheometer tests. The test results show that the average pore size of the crumb rubber after activation with H2O2 solution is significantly smaller than that of the inactivated crumb rubber, and the volume and surface area of the crumb rubber pores change with H2O2 solution activation in a certain pattern. With the increase in H2O2 solution content, the contact surface between the particles increases, the floccules and pores of the powder increase, and the interface degree between the crumb rubber powder and the asphalt is strengthened. Solubility of the rubber hydrocarbon and the release ability of the carbon black particles from the crumb rubber in the asphalt binder increase, but the mechanical properties of the crumb rubber, including the strength, elasticity, and wear resistance, decrease. As a result, a reduction is observed in the elasticity, viscosity, high-temperature rutting resistance, and elasticity of the ACRM asphalt.
Interactive Buckling of Steel LC-Beams Under Bending
Authors: Kolakowski Zbigniew , Jankowski Jacek
Published: May 2019

The present paper deals with the interactive buckling of thin-walled lipped channel (LC) beams under the bending moment in the web plane when the shear lag phenomenon and distortional deformations are taken into account. A plate model (2D) was adopted for LC beams. The structures were assumed to be simply supported at the ends. A modal method of solution to the interactive buckling problem within Koiter’s asymptotic theory, using the semi-analytical method (SAM) and the transition matrix method, was applied. LC-beams, from short through medium-long via long to very long beams, were considered. The paper focuses on the influence of the secondary global buckling mode on the load carrying capacity for the steel LC-beams under bending.
Dynamic Compressive Behaviors of Two-Layer Graded Aluminum Foams under Blast Loading

Published: May 2019

Experimental and numerical analyses were carried out to reveal the behaviors of two-layer graded aluminum foam materials for their dynamic compaction under blast loading. Blast experiments were conducted to investigate the deformation and densification wave formation of two-layer graded foams with positive and negative gradients. The shape of the stress waveform changed during the propagation process, and the time of edge rising was extended. Finite element models of two-layer graded aluminum foam were developed using the periodic Voronoi technique. Numerical analysis was performed to simulate deformation, energy absorption, and transmitted impulse of the two-layer graded aluminum foams by the software ABAQUS/Explicit. The deformation patterns were presented to provide insights into the influences of the foam gradient on compaction wave mechanisms. Results showed that the densification wave occurred at the blast end and then gradually propagated to the distal end for the positive gradient; however, compaction waves simultaneously formed in both layers and propagated to the distal end in the same direction for the negative gradient. The energy absorption and impulse transfer were examined to capture the effect of the blast pressure and the material gradient. The greater the foam gradient, the more energy dissipated and the more impulse transmitted. The absorbed energy and transferred impulse are conflicting objectives for the blast resistance capability of aluminum foam materials with different gradient distributions. The results could help in understanding the performance and mechanisms of two-layer graded aluminum foam materials under blast loading and provide a guideline for effective design of energy-absorbing materials and structures.
Effects of MoO3 + C on Crystallization and Radiative Heat Transfer of CaO–SiO2–B2O3-Based Glassy Fluoride-Free Mold Fluxes
Authors: Shu Qifeng , Li Qiangqi , Fabritius Timo
Published: May 2019

The fluorine in traditional mold fluxes could be harmful in steel-plant environments. Accordingly, fluoride-free mold fluxes have received great attention in recent years. In this work, a method to adjust the crystallization and radiative heat transfer of fluoride-free mold fluxes is proposed. MoO3 and C mixtures (mass ratio: 4:1) were added into CaO–SiO2–B2O3-based mold fluxes and produced MoB, Mo2CB and Mo2C foreign particles. The influences of foreign particles on the radiation of glassy CaO–SiO2–B2O3-based mold fluxes were investigated by measuring the transmissivity of a glassy disk for light in the wavenumber range of 300 to 2500 nm. It was found that transmissivity in all wavenumber ranges were reduced and extinction coefficients were enhanced by the scattering of foreign particles. The effect of foreign particles on crystallization (devitrification) of bulk glassy CaO–SiO2–B2O3-based mold fluxes was also investigated. The crystallization mechanism of glassy mold fluxes disks is mainly surface crystallization. The introduction of foreign particles induced heterogeneous nucleation and the crystallization mechanism of the bulk sample with MoO3% = 2% changed into bulk crystallization.

Fundamental Perceptual Characterization of an Integrated Tactile Display with Electrovibration and Electrical Stimuli
Authors: Komurasaki Seiya , Kajimoto Hiroyuki , Ishizuka Hiroki
Published: May 2019

Tactile displays have been widely studied for many decades. Although multiple tactile stimuli are more effective to improve the quality of the presented tactile sensation, most tactile displays provide a single tactile stimulus. An integrated tactile display with electrovibration and electrical stimuli is proposed herein. It is expected that vibrational friction, pressure and vibration can be presented at the same time through the tactile display. Also, these stimuli only require electrodes for stimulation. Therefore, the tactile display can be easily miniaturized and densely arrayed on a substrate. In this study, a tactile display is designed and fabricated using the micro-fabrication process. Furthermore, the display is evaluated. First, the relationship between a single stimulus and the perception is investigated. The electrovibration and electrical stimuli have a frequency dependence on perception. Second, whether the multiple stimuli with the electrovibration and electrical stimuli are perceivable by the subjects is also evaluated. The results indicate that the multiple tactile stimuli are perceivable by the subjects. Also, the possibility that the electrovibration and electrical stimuli affect each other is confirmed.

We assessed the association between adherence to the Mediterranean diet (MD) and sensory processing in 583 Spanish children aged 3–7 years from the InProS project in Alicante, Spain. Child sensory processing was measured using the short sensory profile (SSP); atypical sensory performance was defined as SSP total score <155; tactile sensitivity <30; taste/smell sensitivity <15; movement sensitivity <13; under-responsive/seeks sensation <27; auditory filtering <23; low energy/weak <26; and visual/auditory sensitivity <19 scores. Adherence to the MD was measured using the Mediterranean diet quality index KIDMED. Multiple Poisson regression models with robust variance, based on the Huber sandwich estimate, were used to obtain prevalence ratios (PR). Our findings suggested that a lower prevalence of atypical tactile and taste/smell sensitivity were associated with having medium (PR = 0.50, 95% CI: 0.25; 0.99; PR = 0.57, 95% CI: 0.33; 0.99, respectively) and high adherence to the MD (PR = 0.58, 95% CI: 0.34; 0.99; PR = 0.33, 95% CI: 0.19; 0.60, respectively), and of atypical low energy/weak with having medium adherence to the MD (PR = 0.37, 95% CI: 0.16; 0.83). A two-point increase in adherence to the MD showed a general positive effect against atypical sensory performance, although it was statistically significant on taste/smell sensitivity (PR = 0.71, 95% CI: 0.59; 0.85) and low energy/weak (PR = 0.80, 95% CI: 0.64; 0.99) subscales. To our knowledge, this is the first study that shows a protective effect of adherence to the MD against prevalence of atypical sensory processing in school-aged children. Further research from longitudinal studies is required to confirm these findings.
Plant/Bacterial Virus-Based Drug Discovery, Drug Delivery, and Therapeutics
Authors: Sokullu Esen , Soleymani Abyaneh Hoda , Gauthier Marc A.
Published: May 2019

Viruses have recently emerged as promising nanomaterials for biotechnological applications. One of the most important applications of viruses is phage display, which has already been employed to identify a broad range of potential therapeutic peptides and antibodies, as well as other biotechnologically relevant polypeptides (including protease inhibitors, minimizing proteins, and cell/organ targeting peptides). Additionally, their high stability, easily modifiable surface, and enormous diversity in shape and size, distinguish viruses from synthetic nanocarriers used for drug delivery. Indeed, several plant and bacterial viruses (e.g., phages) have been investigated and applied as drug carriers. The ability to remove the genetic material within the capsids of some plant viruses and phages produces empty viral-like particles that are replication-deficient and can be loaded with therapeutic agents. This review summarizes the current applications of plant viruses and phages in drug discovery and as drug delivery systems and includes a discussion of the present status of virus-based materials in clinical research, alongside the observed challenges and opportunities.

Published: May 2019

This paper details the design, simulation, and optimization of a low-impedance high repetition rate magnetically insulated transmission line oscillator (MILO) driven by a compact Marx generator. The project goals require the MILO to generate an radio frequency (RF) pulse within the S-band frequency range with a peak output power greater than 1 GW with greater than 10% efficiency. Its design is based on a set of base equation which provide critical component dimensions applied to a three-dimensional model constructed within CST studio suite used in a particle-in-cell (PIC) simulation. Additional to the geometric model, simulation of the MILO with non-ideal material properties and a lumped element modeling of the Marx generator were performed. The results of these simulations then informed changes to the model as to the optimizing performance of the device. Within the framework of the model, the final MILO design achieves the design goals with an approximate RF peak power of 4.5 GW at 2.5 GHz operating in the TM 01 mode when an input driving pulse with a peak voltage of 600 kV while providing 58 kA is applied.

Published: May 2019

A two-step method based on an aqueous two-phase system and Sephadex G-75 was used to separate and purify lectin from the seeds of the Zihua snap bean. The preliminary properties and bioactivity of the Zihua snap bean lectin were characterized by different instrumental methods, such as sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS–PAGE), liquid chromatography-nano electrospray ionization mass spectrometry (Nano LC-ESI-MS/MS), and Fourier transform infrared spectroscopy (FTIR). The hemagglutinating activity of the Zihua snap bean lectin could not be inhibited by glucose, N-acetyl-d-glucosamine, d-galactose, N-acetyl-d-galactosamine, fructose, sucrose, d-maltose, d-trehalose, and lactose. It was found that the hemagglutinating activity of the lectin showed strong dependence on Mn2+ and Ca2+. The thermal and pH stability of the Zihua snap bean lectin was studied by FTIR and fluorescence spectroscopy. Relatively good stability was observed when the temperature was not higher than 70 °C, as well as in the pH range of 2.0 to 10.0. Digestive stability in vitro was investigated. The untreated lectin was relatively stable to pepsin and trypsin activity, but heat treatment could significantly reduce the digestive stability in vitro. Moreover, the lectin showed an inhibitory effect on the tested bacteria (Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), Bacillus subtilis (B. subtilis)), and it also showed a certain inhibitory effect on the growth of Phytophthora infestans (P. infestans) at higher concentrations.

Authors: Xie Sheng , Han Wanli , Xu Xufan , Jiang Guojun , Shentu Baoqing
Published: May 2019

In melt blowing, microfibrous nonwoven material is manufactured by using high-speed air to attenuate polymer melt. The melt-blown air jet determines the process of polymer attenuation and fiber formation. In this work, the importance of lateral velocity on the fiber was first theoretical verified. The lateral diffused characteristic of the air flow field in slot-die melt blowing was researched by measuring the velocity direction using a dual-wire probe hot-wire anemometer. Meanwhile, the fiber path was captured by high-speed photography. Results showed that there existed a critical boundary of the lateral diffusion, however, air jets in the x–z plane are a completely diffused field. This work indicates that the lateral velocity in the y–z plane is one of the crucial factors for initiating fiber whipping and fiber distribution.

Authors: Wang Feng , Chang Li , Hu Yanming , Wu Guangfeng , Liu Heng
Published: May 2019

A series of high impact polystyrenes (HIPS) were successfully prepared by in-situ bulk polymerization. Selective polymerization of butadiene (Bd) in styrene (St) was achieved by using a neodymium bis(2-ethylhexanol)phosphonate/diisobutyl aluminum hydride/diethylaluminum chloride (Nd(P507)3/Al(i-Bu)2H/AlEt2Cl) catalyst, affording a prepolymer with high cis-1,4 content of 96.6% and extremely low styrene content of 1.01%. The prepolymer solution was further subjected to the radical polymerization of styrene to produce HIPS. The impact strength of HIPS increased from 48.5 to 166.2 J/m, with an increase of rubber content from 5% to 15%, whereas the tensile strength at break decreased from 17 to 12.5 MPa. Moreover, the impact strength and the tensile strength at break of HIPS increased from 72.4 J/m to 120.6 J/m and 13.2 to 16 MPa, respectively, as the initiator concentration decreased from 0.05% to 0.01%. HIPS showed the highest impact strength of 84.8 J·m−1 and displayed well “salami” morphology when using a trifunctional 3,6,9-triethyl-3,6,9-trimethyl-1,4,7-triperoxonane initiator.

Published: May 2019

The vascularization of three-dimensional (3D) tissue constructs is necessary for transporting nutrients and oxygen to the component cells. In this study, a vacuum forming method was applied to emboss a vascular pattern on an electrospun membrane so that guided vascular structures could develop within the construct. Two- or six-layer constructs of electrospun membranes seeded with endothelial cells and pericytes were stacked and subcutaneously implanted into mice. Blood vessel formation in the implanted constructs with six alternating layers of flat membranes and membranes embossed with a blood vessel pattern was observed after two weeks of implantation. The formation of blood vessels was observed along the embossed blood vessel pattern in the structure of the embossed membrane laminated at four weeks and eight weeks. Vascular endothelial growth factor (VEGF) and angiopoietin 1 (Ang-1) were highly expressed in the vascularized structures. Therefore, we demonstrated that a structure capable of producing a desired blood vessel shape with electrospun membranes embossed with a blood vessel pattern can be manufactured, and that a variety of structures can be manufactured using electrospun membranes in the tissue engineering era.

Published: May 2019

A small extent of endogenous labile zinc is involved in many vital physiological roles in living systems. However, its detailed functions have not been fully elucidated. In this study, we developed a novel biheteroaryl-based low molecular weight fluorescent sensor, 3-(phenylsulfonyl)-pyrazine–pyridone (5b), and applied it for the detection of endogenous labile zinc ions from lung cancer cells during apoptosis. The electron-withdrawing property of the sulfonyl group between the phenyl ring as an electron donor and the pyridone ring as a fluorophore inhibited the intramolecular charge transfer state, and the background fluorescence of the sensor was decreased in aqueous media. From the structure–fluorescence relationship analysis of the substituent effects with/without Zn2+, compound 5b acting as a sensor possessed favorable properties, including a longer emission wavelength, a large Stokes shift (over 100 nm), a large fluorescence enhancement in response to Zn2+ under physical conditions, and good cell membrane permeability in living cells. Fluorescence imaging studies of human lung adenocarcinoma cells (A549) undergoing apoptosis revealed that compound 5b could detect endogenous labile zinc ions. These experiments suggested that the low molecular weight compound 5b is a potential fluorescence sensor for Zn2+ toward understanding its functions in living systems.
E-Bayesian Estimation Based on Burr-X Generalized Type-II Hybrid Censored Data
Authors: Rabie Abdalla , Li Junping
Published: May 2019

In this article, we are concerned with the E-Bayesian (the expectation of Bayesian estimate) method, the maximum likelihood and the Bayesian estimation methods of the shape parameter, and the reliability function of one-parameter Burr-X distribution. A hybrid generalized Type-II censored sample from one-parameter Burr-X distribution is considered. The Bayesian and E-Bayesian approaches are studied under squared error and LINEX loss functions by using the Markov chain Monte Carlo method. Confidence intervals for maximum likelihood estimates, as well as credible intervals for the E-Bayesian and Bayesian estimates, are constructed. Furthermore, an example of real-life data is presented for the sake of the illustration. Finally, the performance of the E-Bayesian estimation method is studied then compared with the performance of the Bayesian and maximum likelihood methods.
Status and Future Directions for Residential Street Infrastructure Retrofit Research
Authors: Aleksandrova Ksenia I. , McWilliam Wendy J. , Wesener Andreas
Published: May 2019

Residential streets, particularly in automobile-dependent suburban locations, have frequently been perceived as ecologically unsustainable, antisocial, unhealthy, and aesthetically dull from an urban design perspective. However, residential streets can be improved through infrastructure retrofits, particularly by combining green and grey infrastructures and integrating various functions and services. Using a systematic literature review and an adapted landscape services framework, the paper analyses the status of retrofit research and discusses existing composition and spatial integration of green, grey, and green-grey street infrastructure. Findings suggest changing infrastructure compositions in residential streets and a trend toward increased grey and green-grey infrastructure integration. However, functional connectivity is often lacking, and while barriers to implementation have been suggested, few have been tested. While retrofits are potentially able to increase the number and quality of landscape services that support human well-being, more—and possibly longitudinal—research is required to advance and analyze their implementation and provide evidence for their success.

Authors: Pousa Raphael , Costa Marcos Heil , Pimenta Fernando Martins , Fontes Vitor Cunha , Brito Vinícius Fonseca Anício de , Castro Marina
Published: May 2019

In Western Bahia, one of the most active agricultural frontiers of the world, cropland area and irrigated area are increasing at fast rates, and water conflicts have been happening at least since 2010. This study makes a hydroclimatic analysis of the water resources in Western Bahia, from both supply and demand viewpoints. Time series of precipitation for the period 1980–2015 and river discharge for the period 1978–2015 are analyzed, indicating a significant reduction of up to 12% in rainfall since the 1980s, and a reduction in river discharge in all stations studied, in both the rainy season and the dry season. Combined with that, irrigated area has increased over 150-fold in 30 years, and in the most irrigated regions, has increased by 90% in the last eight years only. Seven regions in Western Bahia have been identified where the potential for water use conflicts is critical. Moreover, the combination of reduced availability and increased demand of water resources indicates that, if current trends are maintained, conflicts over water may become more frequent in the next years or decades. A short-term alternative to avoid such conflicts is to largely avoid irrigation during the months with low discharge. However, a monitoring system in which the availability and demand of water resources for irrigation are actually measured and monitored, is the safest path to provide water security to this region.

Published: May 2019

Drainage networks are civil constructions which do not generally attract the attention of decision-makers. However, they are of crucial importance for cities; this can be seen when a city faces floods resulting in extensive and expensive damage. The increase of rain intensity due to climate change may cause deficiencies in drainage networks built for certain defined flows which are incapable of coping with sudden increases, leading to floods. This problem can be solved using different strategies; one is the adaptation of the network through rehabilitation. A way to adapt the traditional network approach consists of substituting some pipes for others with greater diameters. More recently, the installation of storm tanks makes it possible to temporarily store excess water. Either of these solutions can be expensive, and an economic analysis must be done. Recent studies have related flooding with damage costs. In this work, a novel solution combining both approaches (pipes and tanks) is studied. A multi-objective optimization algorithm based on the NSGA-II is proposed for the rehabilitation of urban drainage networks through the substitution of pipes and the installation of storage tanks. Installation costs will be offset by damage costs associated with flooding. As a result, a set of optimal solutions that can be implemented based on the objectives to be achieved by municipalities or decisions makers. The methodology is finally applied to a real network located in the city of Bogotá, Colombia.

The spatial structural position of Hajdúböszörmény (ease of access) and its economic and social endowments which are more favourable than those of its surroundings make the town more desirable as a target of migration. These endowments are rather advantageous on their own, but the specific settlement structure of the town results in the fact that concentrated, unmanageable and majorly segregated social crisis points have developed in some easily circumscribable parts of the settlement which could lead to a social explosion.

enable the hybrid battery to exhibit an average discharge/charge voltage gap of 0.15 V, high Coulombic efficiency of >96%, and superior cycling stability of 120 cycles. This will pave a new pathway to promote metal-air batteries.
Electrically Programmable Terahertz Diatomic Metamolecules for Chiral Optical Control
Authors: Cong Longqing , Pitchappa Prakash , Wang Nan , Singh Ranjan
Published: May 2019

Optical chirality is central to many industrial photonic technologies including enantiomer identification, ellipsometry-based tomography, and spin multiplexing in optical communications. However, a substantial chiral response requires a three-dimensional constituent, thereby making the morphology highly complex to realize structural reconfiguration. Moreover, an active reconfiguration demands intense dosage of external stimuli that pose a major limitation for on-chip integration. Here, we report a low bias, electrically programmable synthetic chiral paradigm with a remarkable reconfiguration among levorotatory, dextrorotatory, achiral, and racemic conformations. The switchable optical activity induced by the chiral conformations enables a transmission-type duplex spatial light modulator for terahertz single pixel imaging. The prototype delivers a new strategy towards reconfigurable stereoselective photonic applications and opens up avenues for on-chip programmable chiral devices with tremendous applications in biology, medicine, chemistry, and photonics.

Our novel neurophysics approach represents a dramatic paradigm shift in analysis and interpretation of the content of the MEP and will give a true meaning to the content of rectified signals. Importantly, this innovative approach allowed unveiling that women exerted more bioenergy than men at the magnetic stimulations used in this study. Revisitation of conclusions drawn from studies published elsewhere assessing rectified EMG signals that have used ambiguous units is strongly recommended.
Encoding and Multiplexing of 2D Images with Orbital Angular Momentum Beams and the Use for Multiview Color Displays
Authors: Chu J. , Chu D. , Smithwick Q.
Published: May 2019

The orthogonal nature of different orbital angular momentum modes enables information transmission in optical communications with increased bandwidth through mode division multiplexing. So far the related works have been focused on using orbital angular momentum modes to
encode/decode and multiplex point-based on-axis signals
for maximum data channel numbers and capacity. Whether orbital angular momentum modes can be utilized to encode/decode
off-axis signals
for multiplexing in two-dimensional space is of significant importance both fundamentally and practically for its enormous potential in increasing the channel information capacity. In this work, a direct use of orbital angular momentum modes to
encode/decode and multiplex two-dimensional images
is realized in a scalable multiview display architecture, which can be utilized for viewing three-dimensional images from different angles. The effect of off-axis encoding/decoding and the resultant crosstalk between multiplexed different two-dimensional views are studied. Based on which, a color display of good image quality with four independent views is demonstrated. The resolution of the decoded images is analyzed and the limitation of this approach discussed. Moreover, a spatially multiplexed data communication scheme is also proposed with such a two-dimensional encoding/decoding approach to significantly enhance the data transmission capacity in free space for future data communication needs.

Selama ini masyarakat dapat mengontrol sesuatu dari jarak jauh dengan menggunakan remote control, akan tetapi pengontrolan tersebut terhambat oleh jarak. Apabila jarak antara alat yang dikontrol dengan pengontrol itu melewati batas toleransinya, maka peralatan tersebut tidak dapat berfungsi sesuai dengan yang diinginkan. Selain itu juga adanya kendala biaya terhadap jarak. Jarak semakin jauh maka biaya pulsa yang dikeluarkan semakin besar. Permasalahan yang sering muncul yaitu perbedaan parameter yang dimiliki KKKS termasuk karakter pengisisan data. Permasalahan yang sering muncul yaitu perbedaan parameter yang dimiliki KKKS termasuk karakter pengisisan data. Khusus untuk KKKS dengan produk minyak terdapat flushing yang seharusnya tidak dimasukkan sebagai volume lifting. Nilai flushing ini berbeda-beda untuk tiap KKKS sehingga perlu penyamaan persepsi dengan KKKS tentang tata cara recording data termasuk waktu pengisian database. Masih terdapat perbedaan waktu di titik CTP, waktu di Poller Migas Control Center dan waktu di Database Server sehingga ada sebagian data flowrate yang terisi tetapi belum sempat ditampilkan di web. Tujuan dari penelitian ini untuk peningkatan efektifitas dan efisiensi pengelolaan usaha dan tata niaga minyak dan gas bumi, khususnya dalam hal monitoring volume lifting minyak dan gas bumi. Pemasangan sistem monitoring yang merupakan integrasi dari sejumlah aplikasi perangkat lunak, perangkat keras serta sejumlah prosedur yang mampu melakukan verifikasi serta penelusuran terhadap kebenaran laporan volume lifting yang disampaikan oleh pihak KKKS
Formulation of Article 488 of the Indonesian Criminal Code Draft: A Portrait of Failure in Construing the Problem of Women's Access to Legal Identity
Authors: Nurtjahyo Lidwina Inge
Published: May 2019

The Draft of the Indonesian Criminal Code has provoked a debate, especially with regard to the articles under the scope of decency. The formulation of Article 488 has the potential to create new problems for women. Especially women who have obstacles in accessing legal identity. This Article 488 is a reflection of the failure of jurists to formulate laws, in understanding women's experience in relation to their access to the right to obtain legal identity, especially in the context of relationship. The criminal law is not the answer to all problems. This paper is compiled using data obtained from field study related to the handling of cases of violence against women under customary law, carried out by the authors and the team from Legal and Community Studies Fields in 2015, 2016 and 2017 in Eastern Indonesia; as well as data on legal and non-legal text analysis. The overall method and analysis of research findings using feminist legal studies and feminist legal theories.

VHS, enfekte balık dokusundaki virüsün, duyarlı doku kültürlerinde izolasyonundan sonra ELISA, virüs nötralizasyon, immunofloresans, immunoperoksidazve komplement fiksasyon gibi serolojik testlerle teşhis edilmektedir. ELISA, tekrarlanabilir olması, kullanımının basit olması, çabuk yapılabilmesi veucuz olmasıyla diğer serolojik testlere göre daha çok tercih edilmektedir.Bu çalışmada VHS antijenini tespit edebilecek tavşandan elde edilen sadece bir antikor kullanıldı. Bu antikor biotin ile işaretlenerek testte konjugatolarak kullanıldı. Üretilen antikorun (anti-VHSV F1 ɣ-globulin fraksiyonu) protein konsantrasyonu 28 mg/ml olarak ölçüldü. Mikroplak kuyucukları 10mikrogram/mililitre (μg/ml) anti-VHSV ɣ-globulin fraksiyonu ile kaplandı. Daha sonra şüpheli örnek ilave edildi. Örnekteki VHSV biotinlenmiş anti-VHSV ɣglobulinfraksiyonuna bağlandı. Bu aşamadan sonra ilave edilen horse radish peroksidase (HRP) enzimi ile işaretli avidin, konjugattaki biotin ile bağlandı. Sonolarak tetramethylbenzidine substrat (TMB) eklenmesiyle renk şekillendi ve ELISA okuyucuda 450 nonometrede (nm) okutturuldu. Bu çalışmada geliştirilen ELISAyöntemi ile bilinen tüm VHSV alttipleri (07.71, HE, 23.75) tespit edilebilmektedir. Yine bu yöntem VHSV’ye oldukça spesifiktir ve İnfeksiyöz HematopoetikNekrozis Virüsu (IHNV), Pike Fry rhabdovirus (PFR), Perch rhabdovirus (PR) ve bilinen tüm İnfeksiyöz Pankreatik Nekrozis Virüsu (IPNV) serotipleriyle çaprazreaksiyon vermemektedir. Sonuç olarak geliştirilen bu ELISA yöntemi 80 nanogram (ng) virüs proteinini ve DKID50 değeri 104,75/0,1 ml olan virüsü tespitedebilmektedir.

Feminist disputes over abortion regulation in Argentina
Authors: Monte Maria Eugenia
Published: May 2019

From a feminist socio-juridical approach, in this research work I investigate the judicial process T.S. assuming that it constitutes an institutionalized site of disputes over the discursive configuration of abortion. T.S. involved Silvia, a woman with a pregnancy diagnosis of an anencephalic fetus who, faced with the refusal of the medical professionals to perform the interruption of the pregnancy in the health system and the request for a court order, initiated a judicial process of amparo in the courts of the city of Buenos Aires with the sponsorship of the lawyers of the foundation Unos con Otros in the year 2000. The Supreme Court of Justice of the Nation ruled the judicial process T.S. in the year 2001. From the discourse analysis of the documents of the judicial process and of in-depth interviews I study how abortion was discursively configured in this judicial process.
Latin America and the socio-legal perspective of the Oñati International Institute for the Sociology of Law
Authors: Ibarra Rojas Lucero
Published: May 2019

This article claims that it is possible to think the Oñati International Institute for the Sociology of Law (IISL) as a center point from which to project a perspective on the sociology of law studies regarding Latin America, through the construction of an epistemic universe as methodological strategy to account for the most relevant topics in the development of this field. Although the discussion can only address the work on Latin America produced by a single institution, it is also embedded in the wider field of sociology of law in the region. It is a bounded state of the art that focusses in the analysis of the main thematic of the epistemic universe: criminology, justice administration, political participation, theoretical perspectives, pluralism and indigenous peoples, economics, gender, urbanism and the legal profession.
A debate on prostitution in Spain
Authors: Arce Becerra Paula
Published: May 2019

The article describes and analyzes the Spanish policies to deal with street prostitution since the end of 2005 when Barcelona’s Bylaw on Coexistence was passed. This local bylaw prohibits and sanctions offering, negotiating or requesting of sexual services in public spaces. Most Spanish municipalities have adopted similar bylaws prohibiting prostitution in the street in recent years. The article aims to analyze the impact of these regulations and their implementation on the rights of people working in prostitution. In order to achieve this it takes into consideration contributions that feminist movements have made to debates on prostitution and public policies.
Collaboration as Feminist Methodology
Authors: Hodson Loveday
Published: May 2019

Participants in the Feminist International Judgments Project have brought to a small group (a judgment-writing chamber) their individual feminist perspectives on international law, and sought to apply their knowledge and method to a highly collaborative judgment (re)writing process. In departing from academic convention and exploring the possibilities and limitations to be found in the collaboration and compromise of writing judgments (rather than focusing on individual viewpoints), participants have had their perspectives constantly challenges. In this paper I explain how this project has foregrounded shared experience in its methodology, thereby making an important connection between feminist theory and methodology. The practical challenges and solutions that participants faced in collaborating on their judgment-writing are also explored.
Announcement: First Edition of IASA-TC 06 Online
Authors: Fleischhauer Carl
Published: May 2019

Archives hold original video recordings in a range of types, from media-dependent, carrier-based analogue videotapes to computer-file-based digital recordings. The appropriate preservation treatments for this array reflect the variation in the source recordings. For analogue videotapes, for example, digitisation is called for. Meanwhile, examples of digital file-based recording may require rewrapping into a fresh file "wrapper" or a combination of digital transcoding and rewrapping.

When complete, IASA-TC 06 will cover the full range of topics in the preceding paragraph, as well as providing advice on shooting ethnographic, documentary, and oral history video footage in a manner that maximizes its "preserve-ability".

Published: May 2019

A three-component reaction involving in situ generation of propargylureas and subsequent Zn(OTf)2-mediated cyclocondensation with a primary amine yielded trisubstituted 2-aminoimidazoles. These findings are in contrast to the previously reported base-promoted unimolecular cyclization of propargylureas (leading to 2-imidazolones) and extend the range of Lewis acid-catalyzed azole syntheses based on N-carbonyl propargylamines.
