Systematic Investigation of the Thermodynamic Properties of Amine Solvents for CO2 Chemical Absorption Using the Cluster-Continuum Model
Authors: Teranishi Kei , Ishikawa Atsushi , Sato Hiroshi , Nakai Hiromi 
Published: February 2017

Abstract
Accurate condensed-phase quantum chemical calculations employing the continuum cluster model were undertaken to systematically examine the reactivity of amine solvents with CO2, a reaction of great importance in CO2 capture and storage technologies. Thirteen amine compounds, including primary, secondary, tertiary, and hindered amines, were considered, and up to ten solvent water molecules were modeled explicitly including continuum solvation. Amine pKa values and reaction Gibbs energies for the formation of bicarbonate, carbamate, and zwitterions were evaluated. Our calculations indicate that increasing the number of explicit water solvents (n) steadily improves computational accuracy, reducing the mean absolute deviation (MAD) of the calculated pKa from the experimental values, i.e., 13.0, 8.6, 1.3, and 0.9 (in pKa units) at n = 0, 1, 6, and 10, respectively. Reaction Gibbs energies calculated with large n for the studied reactions were consistent with the experimental observation that carbamates are the most stable product species, although their stability is lower for secondary amines. However, at n = 0 or 1, positive reaction Gibbs energies were predicted, suggesting that bicarbonate formation would not occur. These results strongly indicate that the trend in the reactivity of CO2-amine reactions can only be correctly predicted by modeling solute-solvent interactions accurately.

SummaryAbnormalities of vena cava inferior are rare malformations and are often discovered by chance . While patients with duplication or left-sided position of the vena cava inferior rarley become clinically apparent the agenesis of the vena cava is associated with an increased rate of deep vein thrombosis. We report a 36-year-old man with recurrent venous thrombosis in which a computer thomography the suspected diagnosis of vena cava inferior agenesis secures and thus a lifelong anticoagulation indicates.
CHIVA with endoluminal procedu res: Laser versus VNUS
Authors: Amsler F. , Mendoza E. 
Published: February 2017

SummaryIntroduction: Since it’s description the CHIVA strategy was performed with surgical techniques. After the introduction of endoluminal heat techniques these might be applied also in the CHIVA context.Method: 104 patients were investigated before and 3–6 months after the treatment of the great saphenous vein (GSV) with CHIVA strategy using enoluminal heat techniques to close the groin segment (VNUS Closure-Fast™ or LASER [1470 nm, Intros radial]). General data (age, sex, BMI) and phlebological data (QoL as reflected in VCSS, clinics as C[CEAP], refilling time after muscle pump measured with light reflection rheography, diameters of GSV at the groin and proximal thigh, as well as diameters of the common femoral vein) were measured and compared.Results: Significant reduction of diameters of GSV at proximal thigh from 6.5 ± 1.6 to 3.7 ± 1.1 and VFC from 15.2 ± 2.3 to 14.8 ± 2.2 were recorded, as well as reduction of clinical scores (VCSS from 5.6 ± 3.1 to 2.2 ± 2 and C[CEAP] from 3.2 ± 1 to 2.1 ± 1.1). Refilling time improved from 20.3 ± 11 to 28.8 ± 10.2. Results are comparable to those achieved after surgical crossectomy and published in other series.Conclusion: The disconnection of the insufficiency point at the saphenofemoral junction seems to be possible in the context of CHIVA Strategy applying endoluminal heat technique. No difference could be found between both techniques, Laser or VNUS Closure-Fast™.
Why Are Losses Less Persistent Than Profits? Curtailments vs. Conservatism
Authors: Lawrence Alastair , Sloan Richard , Sun Estelle 
Published: February 2017

It is well documented that losses are less persistent than profits and that stock prices anticipate the lower persistence of losses. Yet the underlying explanation for these results is unclear. One explanation lies in the abandonment option, whereby firms with losses are more likely to curtail operations (e.g., Hayn [Hayn C (1995) The information content of losses. J. Accounting Econom. 20(2):125–153]). Another explanation involves timely loss recognition stemming from conservative accounting (e.g., Basu [Basu S (1997) The conservatism principle and the asymmetric timeliness of earnings. J. Accounting Econom. 24(1):3–37]). We provide direct evidence that curtailments are an important factor contributing to the lower persistence of losses. An implication of our results is that popular measures of conservatism, such as the measure proposed by Basu, also reflect curtailments. This paper was accepted by Suraj Srinivasan, accounting.

Published: February 2017

Information and Communication Technologies (ICT) have been rapidly prevailed among the children and youths. Personal technologies facilitating the students to gain some learning experiences both in and out of the schools also include many threats. It is important for students to have high awareness of safe internet and computer use to overcome with these threats. In this research, it was aimed to reveal internet security and computer usage awareness profiles of students studying in the secondary school. The data were collected from 2029 students studying in the secondary schools in Bartın Province in Turkey by using a questionnaire developed by the researchers. The data obtained from the questionnaire were analyzed based on the pre-determined themes and the students' information security and computer usage awareness profiles were revealed. The findings indicate that the majority of the students are insufficient regarding information security and computer usage awareness and they could be under risk in online settings towards the threats. In the discussion section, some measures for the parents, schools and policy makers were mentioned to increase students' information security and computer usage awareness.

We planned this study with the aim of determining histological types, clinical, surgical stage and grade of endometrial cancer cases which were followed-up and operated on in our clinic and giving an opinion on epidemiological features. Our study was a retrospective study consisted of 298 patients who had medical operations with the diagnosis of endometrial cancer. Endometrial cancer was diagnosed via dilatation and curettage. Routine preoperative examinations were wanted from the cases. Clinical stage was determined. After the diagnosis, total abdominal hysterectomy and bilateral salpingo-ooforectomy (TAH+BSO) were applied; while only pelvic lymph node dissection was applied on the patients who had good prognostic data, total pelvic and paraaortic lymph node dissection were applied to the group with bad prognostic data. All materials were examined in the pathology laboratory of our hospital. In endometrial cancer staging, FIGO surgical staging system -2009 was used. FIGO was used in grade classification and World Health Organization Classification of Tumors system was used for the histological classification. Our study was composed of 298 patients who had endometrial cancer. Of the patients who were included in the study, average age was 56.54±9.69, BMI average was 31.47±6.20, gravida average was 4.16±2.59, and parity average was 3.41±2.15. Distributions of the patients by surgical stages were as follows; there were 32 patients whose tumor stage was in 1A (%10.7), 127 patients in 1B (42.6%), 47 patients in 1C (15.8%), 18 patients in 2A (6.0%), 7 patients in 2B (2.3%), 30 patients in 3A (10.1%), 2 patients in 3B (0.7%), 30 patients in 3C (10.1%), 2 patients in 4A (0.7%) and 3 patients in 4B (1.0%). Of the patients with endometrial cancer in our study, tumors of 102 patients were (34.2%) in grade I, 139 were (46.6%) in grade II and 57 were (19.1%) in grade III. Because endometrial cancer shows earlier symptoms than the other gynecological cancers, it can be diagnosed in early stages. There is a surgical standard treatment, but it changes according to the stages and general state of the patients.

Published: February 2017

Abstract
Patients with autoimmune rheumatic diseases including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Sjogren’s syndrome (SS), and inflammatory myositis are at increased risk of developing malignancies. Treatment of these conditions, including disease-modifying anti-rheumatic drugs (DMARDs) and biologic therapies, are also associated with increased risk of malignancies.Cancer adds to the disease burden in these patients, affecting their quality of life and life expectancy. The decision in choosing immunosuppressive agents in these rheumatic diseases should take into account the disease severity, expectation for disease control, comorbidities, as well asthe side effects including risks of cancer.
This article does not include the risk of malignancy in patients with the idiopathic inflammatory myopathies, which are well-recognized paraneoplastic conditions.
Magnetoelectric effects in bilayer multiferroic core-shell composites
Authors: Wang H. M. , Pan E. , Chen W.Q. 
Published: February 2017

Abstract
We investigate magnetoelectric (ME) effects in bilayer multiferroic core-shell composites in this paper. The composites are driven by the radial magnetic field and the induced radial deformation/vibration is studied. Two configurations are considered in a concise and uniform manner mathematically. One is spherical and the other is cylindrical. For bilayer core-shell composites, we show that the geometric configuration has a significant effect on the ME effect in multiferroic core-shell composites for both low-frequency and electromechanical resonance ranges. At the low-frequency range, except for the mechanically clamped case, the ME effects in spherical multiferroic composites are always stronger than that in cylindrical ones. At the electromechanical resonance range, for traction-free case, the fundamental resonance frequency of the spherical multiferroic composite is higher than that of the cylindrical one and thus the corresponding ME effect in spherical composite is stronger than that in cylindrical one.

Authors: de Borst René 
Published: February 2017

Abstract
Interface elements are a classical approach to represent discrete cracks, joints and faults. The basic kinematic and constitutive aspects are recapitulated and the extension to hydromechanical conditions is elaborated. A classification is presented of hydromechanical interface elements, depending on the multiplicity of the pressure degree of freedom, and the physical implications of the different possibilities are explained.
Numerical Analysis on the Collapse of a RC Frame
Authors: Nica George Bogdan , Pavel Florin 
Published: February 2017

Abstract
This paper focuses on the collapse analysis of a planar RC frame. This research is based on an experimental study presented in the literature. The analyses are conducted using a dedicated software based on the Applied Element Method. This numerical method is able to model accurately all the structural behaviour stages leading up to the collapse itself. A very good match between the experimental and numerical results is observed. The numerical investigation highlights several behaviour stages for the model RC frame. Moreover, the contribution of the RC slab and the impact of the concrete strength on the overall collapse mechanism is discussed and evaluated through numerical investigation.

BACKGROUND AND OBJECTIVE:
Despite maternal and child health benefits, breastfeeding rates are relatively low among low-income Puerto Rican mothers. This study examined the hypothesis that monthly financial incentives would significantly increase the proportion of breastfeeding mothers at 6 months postpartum compared with Supplemental Nutrition Program for Women, Infants, and Children (WIC) services only among Puerto Rican mothers.

METHODS:
A randomized, 2-arm parallel-group design, from February 2015 through February 2016. Half of the randomized participants received monthly financial incentives contingent on observed breastfeeding for 6 months (Incentive), and the other half received usual WIC services only (Control). Thirty-six self-identified Puerto Rican women who initiated breastfeeding were enrolled. Monthly cash incentives were contingent on observed breastfeeding increasing the amount given at each month from $20 to $70 for a total possible of $270.

RESULTS:
The intent-to-treat analysis showed significantly higher percentages of breastfeeding mothers in the incentive group at each time point compared with those in the control group (89% vs 44%, P = .01 at 1 month; 89% vs 17%, P &lt; .001 at 3 months; 72% vs 0%, P &lt; .001 at 6 months). No significant differences were detected at any time point between study groups for self-reported exclusive breastfeeding rate and infant outcomes (ie, weight, emergency department visits).

CONCLUSIONS:
Contingent cash incentives significantly increased breastfeeding through 6-month postpartum among WIC-enrolled Puerto Rican mothers; however, no significant differences between the study groups were observed on exclusive breastfeeding rate and infant outcomes. Larger-scale studies are warranted to examine efficacy, implementation potential, and cost-effectiveness.

Indeks kelimpahan stok ikan beloso (Saurida micropectoralis) di Laut Jawa cenderungmengalami penurunan dari tahun ke tahun dan untuk mencegahnya perlu bahan masukan yang bersumber dari hasil penelitian yang dijadikan sebagai dasar pengelolaannya. Penelitian dilakukan untukmengkaji beberapa aspek biologimeliputi hubungan panjangberat, nisbah kelamin, tingkat kematangan gonad, panjang pertama kali tertangkap dan panjang pertama kali matang gonad, serta kebiasaan makan ikan beloso. Penelitian dilakukan pada bulanApril–Agustus 2009 di perairan utara Jawa Tengah. Hasil penelitian menunjukkan bahwa nisbah kelamin ikan jantan dan betina berada dalam keadaan tidak seimbang. Pertumbuhan ikan beloso bersifat allometrik positif, dimana pertambahan berat lebih cepat dibandingkan pertumbuhan panjangnya dan tingkat kematangan gonad (TKG) ikan beloso didominasi oleh stadium I. Panjang pertama kali ikan beloso tertangkap lebih kecil dari panjang pertama kali matang gonadnya (Lc < Lm) sehingga akan mengancam kelestariaannya. Ikan beloso bersifat karnivora, dimana makanan utamanya adalah potongan ikan dasar, cumi, dan teri. Index of stock abundance of Lizardfish (Saurida micropectoralis) in Java Sea tend to decreased from year to year. The decline was expected because of the potential of Lizardfish decreasing but the effort continue to rise. The objective of this study is to assess the biological aspects including length-weight relationship, sex ratio, gonadal maturity stage, length of first capture (Lc) and length of first mature (Lm), and feeding habit of Lizardfish in north waters of Central Java. This study was conducted from April to August 2009 in north waters of Central Java. Results showed that the sex ratio between males and females was 1:0,97. Based on Chi-square test it is showed that sex ratio is not balanced. The growth of Lizardfish indicated positive allometric where the weight growth more faster than its length growth. The gonadalmaturity stage of Lizard fish is dominated by the first stage. The length of first capture of Lizardfish was under the length of first mature (Lc < Lm) so that will threaten its sustainability. Lizardfish was indicated carnivorous species where its main food are part of demersal fishes, squids and anchovies.

Aspek kebiasaan makan dan komposisi makanan dari 2 jenis ikan terbang, Hirundicthys oxycephalus dan Cheilopogon cyanopterus, yang tertangkap di perairan Selat Makassar, dipelajari selama bulan Maret sampai dengan Juli 2005. Hasil yang diperoleh menunjukkan bahwa jenis makanan Hirundicthys oxycephalus dan Cheilopogon cyanopterus adalah sama, yaitu copepoda (71,4 dan 68,7%) sebagai makanan utama. Sedangkan makanan tambahan ke-2 jenis ikan ini berupa algae (8,4 dan 12,0%), malacostraca (3,2 dan 3,1%), dan chaetognatha (6,8 dan 6,2%). Luas relung makanan ke-2 jenis ikan ini relatif kecil, berkisar antara 1,79 sampai dengan 2,16, memberikan indikasi bahwa ikan terbang selektif dalam memilih makanan. Selang tumpang tindih relung makanan yang relatif rapat, berkisar antara 0,87 sampai dengan 0,98 menunjukkan bahwa jenis makanan yang dimanfaatkan sama, dan dapat memicu ada persaingan dalam mendapatkan makanan, saat sumber makanan yang tersedia terbatas. This research was conducted during March to July 2005 to obtain the food compotitions of two species of the flying fishes are in Makassar Strait, i. e. Hirundicthys oxycephalus and Cheilopogon cyanopterus. The results show that the food of the flying fishes Hirundicthys oxycephalus and Cheilopogon cyanopterus is similar, which is copepods (71.36 and 68.75%) as the primary food. The additional foods are algae (8.4 and 12.0%), malacostraca (3.2 and 3.1%), and chaetognatha (6.8 and 6.2%). Niche breath of flying fishes is narrow from 1.79 to 2.16, that means flying fishes are selective in collecting their foods. Niche overlap of the flying fishes is narrow from 0.87 to 0.98, it shows that the foods are similar and can cause a competition when the food source is limited.
KAJIAN KUALITAS AIR DALAM EVALUASI PENGEMBANGAN PERIKANAN DI WADUK IR. H. DJUANDA, JAWA BARAT

Published: February 2017

Budi daya ikan di Waduk Ir. H. Djuanda (A=8.300 ha, Zmax=95 m, dan Z=36,5 m) berkembang sangat pesat, sehingga berdampak pada penurunan kualitas air. Tujuan penelitian ini adalah untuk mengevaluasi kualitas air bagi kepentingan perikanan dan mengidentifikasi sumber tekanan tertinggi di Waduk Ir. H. Djuanda. Pengambilan data dilakukan setiap bulan dan tahun 2004 sampai dengan 2006. Pengamatan kualitas air dilakukan dengan metode pengambilan contoh air secara horisontal dan vertikal. Hasil penelitian menunjukkan bahwa sumber utama degradasi kualitas air adalah bahan organik yang berasal dari Waduk Cirata. Distribusi vertikal oksigen terlarut di perairan menunjukkan ada stratifikasi dengan kedalaman epilimnion yang sangat tipis. Berdasarkan pada analisis kandungan fosfat dan nitrogen, waduk ini telah mengalami perubahan dari eutrofik (tahun 2004) menjadi hipereutrofik (tahun 2005 dan 2006). Degradasi tersebut cenderung meningkat seiring dengan peningkatan jumlah unit karamba jaring apung yang dikembangkan di Waduk Cirata dan Waduk Ir. H. Djuanda. Kondisi ini menunjukkan bahwa pengembangan kegiatan budi daya dalam karamba jaring apung telah melampaui daya dukung dan cenderung mencemari perairan. Upaya mengatasi degredasi tersebut dapat dilakukan dengan 2 cara, yaitu 1) mengurangi usaha budi daya ikan dalam karamba jaring apung di Waduk Ir. H. Djuanda dan Cirata dan 2) menebarkan jenis ikan yang mampu memanfaatkan plankton secara efektif. Development of fish culture in Ir. H. Djuanda Reservoir has been expanded very fast, so it might cause the degradation of water qualities. The aims to evaluated water quality for fisheries purpose and identify the primary pressure source in Ir. H. Djuanda Reservoir. The data were collected every month during year of 2004 to 2006. Water sampling was done by vertical and horizontal. The result indicates that the primary source degradation of water qualities was organic materials from Cirata Reservoir. Stratification of dissolved oxygen in the water column indicates with very thin epilimnion layer. Based on phosphate and N-compuonds analysis, Ir. H. Djuanda Reservoir was changed from eutrophic in year 2004 to hipereutrophic in year 2005 and 2006. The degradation tends to increase with developing floating cage unit numbers in Cirata and Ir. H. Djuanda Reservoir. This condition shows that the development of fish culture in floating cage seems have be over the carry capacity of reservoir and tend to spread the pollution in the water. It effort suggest that the would two ways, i.e. 1) decrease of fish culture activities using be done refering floating cages in Ir. H. Djuanda and Cirata Reservoir and 2) stocking of fish species which are capable to utilized the plankton effectively.
