Abstract
The green synthetic route for the synthesis of semiconductor nanoparticles has received special attention recently due to its features, such as low cost and environmental friendliness. The (Z)-2-(pyrrolidin-2-ylidene)thiourea was used as a ligand and allowed to react with zinc acetate to form the ZnS nanoparticles through the homogeneous precipitation method. The polyvinyl pyrrolidone and polyethylene glycol were employed as capping agents, whereas the ammonium solution was used as an activator for the stabilizers. The effects of the concentration of the capping agents on ZnS nanoparticles were investigated. The poly ethylene glycol (PEG)- or (polyvinylpyrollidone) PVP-capped zinc sulfide nanoparticles were then incorporated with polydadmac to form the polymer nanocomposites. The results from various sophisticated instruments, such as spectrophotometer (UV-Vis), photoluminescence (PL), Fourier transform infrared (FTIR), X-ray powder diffraction (XRD), transmission electron microscope (TEM), and scanning electron microscopy (SEM), reveal that the concentrations of capping agents and ammonium solution has great effects on nanomaterials.
Studying individual differences in the social environment to better understand language learning and processing
Authors: Lev-Ari Shiri 
Published: October 2016

Abstract
People learn language from their social environment. Therefore, individual differences in the input that their social environment provides could influence their linguistic performance. Nevertheless, investigation of the role of individual differences in input on performance has been mostly restricted to first and second language acquisition. In this paper I argue that individual differences in input can influence linguistic performance even in adult native speakers. Specifically, differences in input can affect performance by influencing people’s knowledgebase, by modulating their processing manner, and by shaping expectations. Therefore, studying the role that individual differences in input play can improve our understanding of how language is learned, processed and represented.
Native English speakers’ structural alignment mediated by foreign-accented speech
Authors: Chun Eunjin , Barrow Julia , Kaan Edith 
Published: October 2016

Abstract
With the growth of language variation it is becoming increasingly important to understand how monolingual speakers’ language processing can differ when responding to various speakers. This study investigated native English speakers’ structural alignment to different accents of English (American, Korean, and Indian speaker of English) using a picture description paradigm. More specifically, we explored the effect of accent type and familiarity with a speaker’s accent on syntactic alignment. American-English speaking participants were primed less for a PO construction when listening to a native American-English speaker than in response to English speakers with a non-American accent (Korean and Indian English). A similar pattern was observed in the analysis using perceived familiarity with accents. These results support the claim that social factors, (e. g., speakers’ accents or perceived familiarity with the accents) can automatically influence language processing, and should be taken into consideration for psycholinguistics theoretical accounts of syntactic priming.
Age of Arrival (AOA) effects on anaphor processing by Japanese bilinguals

Published: October 2016

AbstractThis study investigates the role of exposure to English on discourse-reference processing by native Japanese speakers. Shoji et al. (2016a, The repeated name penalty, the overt pronoun penalty, and topic in Japanese.Journal of Psycholinguistic Research.http://link.springer.com/article/10.1007 %2Fs10936-016-9424-4) found that Japanese-English bilinguals residing in the United States show a Repeated Name Penalty (RNP; Gordon et al. 1993. Pronouns, names, and the centering of attention in discourse.Cognitive Science17. 311–347) and an Overt Pronoun Penalty (OPP; Gelormini-Lezama and Almor 2011, Repeated names, overt pronouns, and null pronouns in Spanish.Language Cognitive Processes26. 437–454) in Japanese with both topic (wa-marked) subject anaphors and non-topic (ga-marked) subject anaphors, indicating that the different morphological markings on anaphors do not alter these effects. In contrast, more recent data collected from L1-immersed Japanese speakers residing in Japan (Shoji et al. 2016b,The repeated name penalty and the overt pronoun penalty in Japanese. Unpublished manuscript) show that these speakers do not show a RNP or an OPP for topic-marked anaphors. Here we report a reanalysis of Shoji et al.’s (2016a) results showing that these effects are moderated by participants’ Age of Arrival (AOA; i. e. the age at which participants first arrived to the place where their second language is regularly spoken). Participants with an early AOA showed differential processing patterns for topic-marked anaphors and non-topic anaphors, while participants with late AOA did not. We propose as an explanation that early AOA bilinguals represent different languages separately, while late AOA bilinguals tend to rely on a single unified language system.
Pragmatic accommodation as a catalyst for the development of (non-)finiteness
Authors: Slomanson Peter 
Published: October 2016

AbstractA morphological asymmetry is shared by certain Dravidian (and Finnic) languages. The phonological shape of a negation element is dependent on the finiteness of the verb it negates. Pragmatic factors are identified that could motivate the development of this shared asymmetry, using evidence from the grammar of a Dravidian-influenced contact language. I will show that contrastive finiteness marking (finite and non-finite morphology) can facilitate the development of pragmatically-motivated linear reordering of affirmative clauses and negated clauses in order to accommodate new information structure conventions, extending the contrast to negated verbs by expanding the functional range of a negative imperative marker.Radical contact languages resulting from collective adult second language acquisition in naturalistic social contexts are typically presumed to feature reduced functional morphology, in which only highly salient contrasts, such as temporal contrasts, are formally instantiated. If a formal finiteness contrast and other relatively marked properties (“complexity”) could develop in a highly analytic contact language that did not previously have them, this suggests that such a sequence of changes is in fact as plausible among genetically-unrelated languages in a sprachbund as it is over longer periods of time in genetically-related languages. We can observe this by examining grammatical change in a language that previously lacked both a finiteness contrast and a corresponding negation asymmetry, but which developed both the contrast and the asymmetry as a result of contact with a genetically-unrelated language that has analogous properties.Sri Lankan Malay (SLM) has undergone grammatical change due to contact with Dravidian (primarily Sri Lankan Muslim Tamil). Several of these changes involve verb morphology and syntax, and are plausibly motivated by discourse-pragmatic triggers. Consideration of tense and (non-)finiteness phenomena, as well as their reflexes in SLM negation, suggests a discourse-pragmatic motivation for these changes. Two discourse processes could conspire to motivate the development of the new morphology in SLM. The first is a clausal asymmetry, in which the predicate representing the most recent event is ordinarily in focus, indicated by tense morphology and position of the clause relative to clauses referring to subsequent events. The second is the communicative need to reassign focus in certain contexts to a temporally non-primary clause, one referring to an event that did not take place first. In spite of a constraint in Dravidian languages blocking the marking of functional contrasts under negation (so that only a negation morpheme can be prefixed to the verb), negation morphology encodes an obligatory finiteness contrast, optimally supporting these information-structuring processes. The clause describing the most recent event in a sentence remains visibly finite under negation, when a temporally secondary clause is focused.

It is crucial to understand the microbial community associated with the host when attempting to discern the pathogen responsible for disease outbreaks in scleractinian corals. This study determines changes in the bacterial community associated with Montipora sp. in response to black band disease in Indonesian waters. Healthy, diseased, and dead Montipora sp. (n = 3 for each sample type per location) were collected from three different locations (Pari Island, Pramuka Island, and Peteloran Island). DGGE (Denaturing Gradient Gel Electrophoresis) was carried out to identify the bacterial community associated with each sample type and histological analysis was conducted to identify pathogens associated with specific tissues. Various Desulfovibrio species were found as novelty to be associated with infection samples, including Desulfovibrio desulfuricans, Desulfovibrio magneticus, and Desulfovibrio gigas, Bacillus benzoevorans, Bacillus farraginis in genus which previously associated with pathogenicity in corals. Various bacterial species associated with uninfected corals were lost in diseased and dead samples. Unlike healthy samples, coral tissues such as the epidermis, endodermis, zooxanthellae were not present on dead samples under histological observation. Liberated zooxanthellae and cyanobacteria were found in black band diseased Montipora sp. samples.
CATFISH KECIL UNIK, Corydoras sp. UNTUK AKUARIUM, TINGKAH LAKU BIOLOGI DAN REPRODUKSINYA
Authors: Satyani Darti 
Published: October 2016

Corydoras sp. termasuk dalam familia Collichthyidae, kelas Siluridae dan sangat dikenal olah para hobiis ikan hias air tawar. Genus Corydoras yang berasal dari Amerika Selatan ini mempunyai banyak spesies tetapi yang banyak beredar dan sudah dibudidayakan ada 10 spesies yaitu C. aeneus, C. adolfoi, C. barbatus, C. paleatus, C. panda, C. pygmaeus, C. rabauti, C. septentrionalis, C. sterbai, dan C. sychri. Selain ukurannya yang umumnya kecil (maksimum 7,5 cm) dibandingkan dengan jenis catfish lain, jenis ini mempunyai dua baris sisik keras. Bentuk badannya kompak agak pipih ke samping dengan mulut menghadap ke bawah. Hidup merayap di dasar pada suhu 24°C--28°C (tergantung spesiesnya); pH 7,0--7,5; dan hardness sekitar 10° dH. Disebut “tukang bersih-bersih” karena senang membersihkan dinding akuarium dengan mulutnya. Tingkah laku reproduksinya amat unik. Sebelum ovulasi induk betina akan menempatkan mulutnya kearah genital induk jantan yang dikenal dengan “posisi T” dan akan mengisap spermanya. Sperma ini akan dilepas melewati usus bersama dengan lepasnya telur kedalam “kantong” yang dibentuk oleh kedua sirip perutnya. Pembuahan efektif terjadi di sini. Kemudian telur akan dilekatkan ke substrat atau objek (daun, batu datar, dan sebagainya) yang sebelumnya telah dibersihkan oleh induk jantannya. Telur yang ditinggalkan akan menetas di substrat bila kondisi airnya sesuai dan cukup baik.
BUDIDAYA IKAN PATIN DI VIETNAM: Suatu Kajian Untuk Pengembangan Budidaya Ikan Patin Indonesia
Authors: Meilisza Nina 
Published: October 2016

Budidaya ikan patin telah lama dilakukan di Indonesia dan menjadi salah satu komoditas penting dalam dunia perikanan. Ikan patin tidak hanya populer sebagai ikan konsumsi namun juga disukai sebagai ikan hias saat masih kecil karena bentuk, warna dan pergerakannya yang indah. Perkembangan budidaya ikan patin di Indonesia tidak secepat yang terjadi di Vietnam. Sebagai negara yang memiliki luas lahan perairan umum dan potensi sumberdaya manusia yang cukup besar, Indonesia hanya mampu menempati posisi kelima dalam produksi patin dunia. Produksi ikan patin Vietnam mencapai jumlah 1,2 juta ton di tahun 2007, sedangkan Indonesia hanya mampu memproduksi sekitar 36.250 ton. Perbandingan ini sangat signifikan dan menjadi pertanyaan besar apa saja yang telah dilakukan oleh pelaku perikanan kita. Budidaya ikan patin telah memberikan kontribusi besar dalam perekonomian Vietnam dan menjadi penggerak roda ekonomi masyarakatnya. Keberhasilan Vietnam perlu dipelajari dan dikaji sebagai acuan dalam mengembangkan budidaya ikan patin di Indonesia.
PAKAN BUATAN UNTUK PENGEMBANGAN BUDIDAYA IKAN DISCUS (Symphysodon discus) DI INDONESIA
Authors: Kusrini Eni , Priono Bambang 
Published: October 2016

Ikan discus termasuk ikan hias yang agak sulit untuk dibudidayakan sehingga para pembudidayanya masih sangat terbatas. Cara budidaya yang sekarang sudah perkembang adalah masih secara konvensional. Larva ikan discus yang baru menetas sampai berumur satu minggu masih diasuh induknya karena masih tergantung dari lendir induk sebagai sumber makanannya, sehingga akan menunda induk lebih lama memijah berikutnya dan kanibalisme dapat terjadi terhadap larvanya sendiri. Artificial food (pakan buatan) yang terbuat dari telur ayam yang dibuat menyerupai lendir induk ikan discus merupakan sebuah inovasi dari pembudidaya ikan discus. Pemberian pakan buatan tersebut selain dapat memacu pematangan gonad induk ikan discus juga dapat menyelamatkan larva yang biasanya dimakan oleh induk-induknya (mengurangi kanibalisme).
BUDIDAYA IKAN SISTEM KERAMBA JARING APUNG GUNA MENJAGA KEBERLANJUTAN LINGKUNGAN PERAIRAN WADUK CIRATA
Authors: Ardi Idil 
Published: October 2016

Eksistensi budidaya ikan sistem keramba jaring apung di Waduk Cirata terus berlangsung, meskipun banyak hasil penelitian yang menyatakan bahwa lingkungan perairan waduk sudah menurun. Keberadaan budidaya ikan sistem keramba jaring apung (KJA) tetap bertahan tidak terlepas dari dukungan berbagai macam sarana produksi ikan (saprokan). Namun demikian, pada tingkat pengelolaan budidaya yang tidak terkendali tentu akan berdampak buruk bagi lingkungan perairan waduk. Penelitian bertujuan mengkaji pola budidaya sistem keramba jaring apung yang dapat meminimalisasi beban sisa pakan. Penelitian dilakukan dengan metode survai lapang dan wawancara, serta pengisian kuisioner dengan responden pembudidaya ikan sebanyak 103 orang. Hasil penelitian menunjukkan bahwa sisa pakan dari aktivitas budidaya ikan sistem KJA yang terbuang ke lingkungan perairan waduk sebesar 23 kg fosfor (P) per petak KJA atau sebesar 900 ton P per tahun. Besarnya sisa pakan yang terbuang disebabkan oleh tingkat penggunaan pakan yang tinggi (FCR 1,51%), kandungan P pakan yang tinggi dan tingkat penyerapanpakan yang rendah terutama pada ikan mas.
Iris Patterns As A Biometric Tool For Forensic Identifications: A Review
Authors: Jagmahender Singh Sehrawat  , Deeksha Sankhyan  
Published: October 2016

Human biometric features are considered unique, permanent, measureable and objective traits used as authentic tools for identification of an individual. Biometric authentications are increasingly utilized for identifying a genuine user or an imposter. The automated iris pattern recognition is based on the unique, non-intrusive and un-imitable micro-features of human iris. Several mathematical and statistical algorithms have been suggested for extracting and encoding iris minutiae used for pattern recognitions in automated systems. Iris scanning is an easy and non-invasive technique, having comparatively lower false acceptance and rejection rates and negligible chances of manipulations and spoofing. Despite of some limitations, iris recognition is considered a promising advancement in forensic sciences. Present review has presented the iris recognition knowledge in nutshell to the readers.

Published: October 2016

Abstract
The development increasingly involves reservoirs with low and ultra-low permeability reservoir. "Traditional" welltest analysis technologies in such reservoirs lose their efficiency (Davletbaev A.Y., Zhylko E. Y. etc. 2015, Loznyuk O.A. etc. 2015) as they require long-time shut-in (about 1 month and more), which causes huge losses in production (Davletbaev A.Y., Islamov R. R etc. 2015). In such conditions, analysis of usual operation data analysis and decline analysis become relevant (Arps J.J. 1945, Fetkovich M.J. 1980, Ilk D., Blassingame T.A. 2013, Doublet D.E. etc. 1994). This method has a lot of limitations, in particular, it is necessary to know the value of the reservoir pressure at the moment of the reservoir operation for interpretation, which is not always possible in the conditions of the operation and maintenance phase. The present work offers the method permitting to increase the informational content of the decline analysis, as well as to determine the value of initial reservoir pressure by combining «short» build-up welltest analysis with decline analysis in the operating well.
Express-Method of Forecasting The Maximum Annular Pressure in Mechanized Production Wells During Pressure Transient Analysis

Published: October 2016

Abstract
At the present time one of the most common methods of well testing is pressure build-up test at the shut-in of production well. When the well is closed for research the process of bottomhole pressure (BHP) increase is accompanied by a change in the dynamic head and increasing the gas pressure at annular space (Shagiev, 1998). Growth of casing pressure above limit pressure can lead to technical problems at wellhead. This paper describes a method for predict the pressure in the annular space and the dynamic head in the end of the pressure transient test and bottomhole pressure build-up to the current reservoir pressure.
Express-method of forecasting of casing pressure is tested on experimental examples of research in mechanized wells. In most cases, calculated casing pressure value corresponds with the measured data (successful prediction by this method is 70%).
In most cases, forecasting method of casing pressure recovery for vertical mechanized wells allows to determine the possible excess casing pressure above the critical pressure at the wellhead (for example, a possible increase above of test pressure and limit pressure which can connect with some gaps at the wellhead) pressure build-up test. Presented express-method of forecasting can be used in the selection of wells-candidate for well testing, at prevention and reduction of potential problems and for discontinuation well testing due to high casing pressure, improving the success of well testing.
