In fl uence of internals on counter-current bubble column hydrodynamics : Holdup , fl ow regime transition and local fl ow properties

Bubble columns are frequently studied without considering internals (open tube bubble columns). However, in most industrial applications, internal devices are often added to control heat transfer, to foster bubble break-up or to limit liquid phase back mixing. These elements can have significant effects on the multiphase flow inside the bubble column reactor and the prediction of these effects is still hardly possible without experimentation. In this paper, we study experimentally a counter-current gas–liquid bubble column in the open tube and annular gap configurations. In the annular gap bubble column, two vertical internal tubes are considered. The column has an inner diameter of 0.24 m, and the global and local hydrodynamic properties are studied using gas holdup measurements and a double-fiber optical probe. The gas holdup measurements are compared with the literature and used to investigate the flow regime transition. A double-fiber optical probe is used to acquire midpoint data and radial profiles of the local properties to study the flow properties and to further investigate the flow regime transition. The counter-current mode is found to increase the holdup, decrease the bubble velocity and cause regime transition at lower superficial gas velocity. The holdup curves in the annular gap and open tube configurations are similar in shape and values, suggesting that the presence of internals has a limited influence on the global hydrodynamic. In addition, it is found that the presence of the internals stabilizes the homogeneous regime in terms of transition gas velocity and holdup. & 2016 Elsevier Ltd. All rights reserved.
Upward Mobility and Legislator Support for Education Reforms ∗

This paper investigates how upward mobility affects legislator voting behavior towards education reforms. We develop an electoral competition model where voters are parents who value the future economic status of their children, while children’s economic status is affected by public education and upward mobility. The model predicts a decrease in legislator support for redistributive education policy with a rise in upward mobility. We test this hypothesis using a newly compiled dataset of roll call voting on California education legislation matched with electoral district-level upward mobility. Our findings suggest that the likelihood of a legislator voting “no” on redistibutive education bills increases by 10% when upward mobility in his electoral district increases by a standard deviation.
The Effects of Tax Reform on the Labor Supply and Welfare of Korean Female Workers : Evidence from the Collective Decision Approach ∗

This paper investigated the question regarding how the recent tax reform in Korea affected the welfare of female workers. To answer the question, we referred to the collective bargaining model. We estimated the income sharing rule for the working couples and implemented some counterfactual policy experiments. We found that the average income sharing between wife and husband is around 81 percent. The policy simulation reveals that the recent tax reform tends to increase the labor supply of female workers while their welfare tends to be deteriorated. ∗All remaining errors are our own. †Corresponding author, associate professor, email: sjwoo@mju.ac. kr ‡Assistant professor, email: song@uos.ac. kr
Thunderstorm hail and lightning detection parameters based on dual‐polarization Doppler weather radar data

Four years (2011–2014) of the summer period (May–September) dual‐polarization Doppler C‐band weather radar data for Sürgavere, Estonia, were examined to determine the best indicator for cloud‐to‐ground lightning activity. Furthermore, the legacy radar‐derived hail indicator probability of hail and the storm maximum reflectivity were compared with the polarimetric hydrometeor classification algorithm (HCA) to establish a link between them and ensure data continuity. The study is based on convective storm cells identified from radar reflectivity data, using a 35 dBZ reflectivity threshold. Applying this threshold to the radar data resulted in 123 360 individual storm cells. It was found that 33.9% of the identified cells produced lightning and 25.9% hail. The number of individual storm cells on average is highest in the afternoon at 1600 local time and the mean storm cell area is largest in the evening at 2100 local time. Echo top 15 dBZ (ET15), ET20 and ET25 achieved the highest scores in terms of critical success index (0.39, 0.39 and 0.38 respectively), Heidke skill score (0.24, 0.26, 0.27) and equitable threat score (0.14, 0.15, 0.16). The graupel class of the dual‐polarization radar hydrometeor classification showed a similar performance to the 35 dBZ echo top. It was also shown that the reflectivity value just below 50 dBZ indicates the best skill for detection of hail, if HCA hail detection is used as the ground truth. The probability of hail value that shows the best agreement with the HCA hail class is 0.2.
Association between TNF-α level and TNF-α gene polymorphisms in liver cirrhosis of Iraqi patients

Tumor necrosis factor alpha (TNF-α) is a essential pro inflammatory cytokine which involved in pathogenesis of liver cirrhosis. Current study was designed to examine the association between TNF-α level and TNF-α gene polymorphisms in liver cirrhosis of Iraqi patents. Subjects and methods: Sixty nine liver cirrhosis Iraqi patents (Mean age 54 ± 23 years),including 43 (32 men and 11 woman) with chronic viral hepatitis and 26 men of liver cirrhosis Iraqi patents with alcohol drinking history in comparison with 50 (25 men and 25 women) of apparently healthy nonalcohol drinking as a control group (Mean age 56 ± 21 years), blood samples were obtained from the subjects. Level of TNF-α was assessed by using Enzyme-Linked Immunosorbent assay (ELISA) whereas 308 TNF-α gene polymorphism was detected by PCR restriction fragment length polymorphism (PCR-RFLP). Results: Levels of TNFα were significantly increased (P<0.01) among all liver cirrhosis patent groups when compared with control group, and the group of chronic viral hepatitis had the highest TNF-α value (38.40 ± 3.45 pg/ml) while the value of liver cirrhosis group was (35.41 ± 2.15 pg/ml) and the alcohol drinking history group was (31.72 ± 3.49) as compared with control group (14.33 ± 1.62) with significant difference (P≤ 0.01). The results of the relationship between 308 TNF-α polymorphisms and liver cirrhosis showed that the G/G genotype was 14(20.3%), GA genotype was18(26.1%), AA genotype was 37 (53.6%), G alleles were 23(33.3%), A alleles were 46(66.6%) with significant difference (P≤ 0.005) and in chronic viral hepatitis patents the G/G genotype was 6 (13.9%) , GA genotype was 8(18.6%), AA genotype was 28 (65.1%), G alleles were 10(23.2%), A alleles were 31(72.1%), with significant difference (P≤ 0.01), while in liver cirrhosis with alcohol drinking history the G/G genotype was 8(30.7%), GA genotype was10(38.5%), AA genotype was 9 (34.6%), G alleles were 13 (50%), A alleles were 15(57.7%), while in control G/G genotype was 33 (66%), GA genotype was14(28%), AA genotype was 3 (6%), G alleles were 45(90%),A alleles were 16 (32%) with significant difference (P≤ 0.01), the result revealed there was no significant differences between these genotype in both the liver cirrhosis patients and control.
Determinants of Rural Children ’ s Participation in Cassava Processing in Egbeda Local Government Area of Oyo State

Rural children are in recent times confirmed to be engaged in numerous farm activities most especially processing, particularly cassava, mainly to augment the income of their respective parents and in turn improve household welfare but in many cases this is detrimental to their livelihood and negatively affects their general lifestyle. The study examined the determinants of rural children’s participation in cassava processing in Egbeda Local Government Area of Oyo State. Multi-stage sampling technique was used in selecting a total of 150 respondents using instruments like copies of structured questionnaire and recording gadget such as cell phone. Primary data collected were analysed using descriptive statistics and parametric tool, Probit model in determinants of rural children’s participation in cassava processing. The result of the maximum likelihood estimate (MLE) of probit regression showed that age, dependency ratio, parent’s marital status, financial need gap, daily wage, technology type, and number of friends kept by respondents amongst others were all significant at the least of 10% level and positively affected participation of rural children in cassava processing. Poor remuneration (29.30 percent) was voted highest for the constraints confronted while income generation (58 percent) remained the main reason for rural children’s engagement in cassava processing. Garri was the most common cassava product produced by the respondents. It was recommended that, crop processing related training be given to farmers who are into cassava processing in the study area.
Energy Efficiency Evaluation of RSVP-TE Extensions for Survivable Translucent WSON Networks

e Abstract Energy consumption in communication networks is ever increasing. The target of reducing the energy can be approached from different points: е nergy usage reduction of different hardware components, sleep mode, energy efficient routing and signalling protocol extensions. Another interesting aspect in communication networks is that connections must be protected against failures. The backup resources are normally connected and powered on, which also contributes to the energy budget. Using Shared Path Protection (SPP) minimizes the protection resources by efficient sharing of wavelengths, regenerators and wavelength converters. Furtheron signaling extensions that can reduce the energy usage by reducing the usage of electrical ports can be designed. In this paper, we use GMPLS extensions to integrate energy-efficiency considerations into the network protection paradigm; and we use OPNET Modeler to evaluate our proposal.
Kazakh and Russian Languages Identification Using Long Short-Term Memory Recurrent Neural Networks

Automatic language identification (LID) belongs to the automatic process whereby the identity of the language spoken in a speech sample can be distinguished. In recent decades, LID has made significant advancement in spoken language identification which received an advantage from technological achievements in related areas, such as signal processing, pattern recognition, machine learning and neural networks. This work investigates the employment of Long Short-Term Memory (LSTM) recurrent neural networks (RNNs) for automatic language identification. The main reason of applying LSTM RNNs to the current task is their reasonable capacity in handling sequences. This study shows that LSTM RNNs can efficiently take advantage of temporal dependencies in acoustic data in order to learn relevant features for language recognition tasks. In this paper, we show results for conducted language identification experiments for Kazakh and Russian languages and the presented LSTM RNN model can deal with short utterances (2s). The model was trained using open-source high-level neural networks API Keras on limited computational resources.
A Brief History of Psalms Studies

The purpose of this article is to provide and up-to-date review of the major periods in the history of psalms studies, with particular reference to the recent quest for the editorial shape and purpose of the Book of Psalms. The authors divide the history of interpretation into four major periods—pre-critical, historical-critical, formcritical and redaction-critical. Pre-critical interpretation (before 1820) generally considered the shape of the Psalter significant, but made no formal attempt to identify its purpose. During the historical-critical (1820-1920) and form-critical (1920-1980) periods, scholars treated the Psalter as an ad hoc collection of lyrics for use in temple worship; the focus was on the historical Sitz im Leben of the psalms. The modern interest into the editorial shaping of the Book of Psalms marks a renewed belief in the fact that the order of the psalms is significant and the first serious attempt to discern the editorial purpose or message of the Psalter as a
Value matters or values matter? An analysis of heterogeneity in preferences for sustainable investments

Pension fund investments have a substantial influence on sustainability. We analyze preferences for sustainable investment among a representative cross-section of 2486 pension fund participants in the Netherlands, through a questionnaire survey fielded in the LISS panel. In contrast to standard investment theory, we find that sustainable investments are commonly favored, even if they harm financial interests. To explain variation among participants’ preferences for sustainable investments, we test socio-demographic factors suggested by dominant neoclassical investment and behavioral finance theories. Moreover, we add to the existing literature by developing an alternative cultural-theoretical explanation that stresses the role of value orientations. We estimate linear and generalized ordered logit regression models, and find little support for neoclassical and behavioral finance theories, but substantial support for the importance of value orientations. Given established patterns of value-change, this finding suggests that a further increase in the demand for sustainable investments across developed economies is a likely scenario.

THE FIRST LAMBEOSAURIN ( DINOSAURIA , HADROSAURIDAE , LAMBEOSAURINAE ) FROM THE UPPER CRETACEOUS OJO ALAMO FORMATION ( NAASHOIBITO MEMBER ) , SAN JUAN BASIN , NEW MEXICO

A nearly complete robust left humerus (SMP VP-2263) and right jugal (SMP VP-1534) belonging to a lambeosaurin lambeosaurine (= Lambeosaurus + (Corythosaurus + Hypacrosaurus)) dinosaur have been recovered from two separate localities in the Naashoibito Member (Ojo Alamo Formation), San Juan Basin, New Mexico. Measurements of the humerus are: length = 550 mm; deltopectoral crest length = 260 mm; deltopectoral width = 135 mm. The robust morphology and measurements of the humerus confirm it pertains to a member of the lambeosaurin clade, which we formally establish. The jugal has a maximum rostrocaudal length of 255 mm and a shape that is inconsistent with the jugals of all species of Parasaurolophus. These specimens, which are very similar to the humerus and jugal of Corythosaurus and Hypacrosaurus, constitute definite records of lambeosaurines from the Naashoibito Member, despite previous erroneous reports of the occurrence of Parasaurolophus tubicen from this horizon. The putative hadrosaurine, NMMNH P-19147, is re-interpreted as a lambeosaurin lambeosaurine, based primarily on the morphology of the pubis. Recovery of additional lambeosaurine material in the Naashoibito Member lends further support to a pre-Lancian age for this interval and for the Alamo Wash local fauna.

Fatores de risco associados à infecção de ferida cirúrgica e sepse neonatal Antibiotic Prophylaxis in Cesarean section : Wound infection and Neonatal Sepsis risk factors

Justification and objectives: Post-surgical site infection (SSI) is one of the major complications of cesarean section and preoperative antimicrobial prophylaxis is indicated before the incision or after umbilical cord clamping. The aim of this study is to compare the SSI rates and neonatal sepsis with two different prophylaxis protocols. Methods: Prospective observational study, carried out 2012 to 2015, at a reference maternity hospital for high obstetric risk patients. All pregnant women who underwent cesarean section and their newborns were included. Information was obtained when they were contacted by telephone call and by medical records. Infection criteria followed National Healthcare Safety Network and Agência Nacional de Vigilância Sanitária recommendations. Analysis was performed using the Statistical Package for Social Sciences. The study was approved by the Research Ethics Committee. Results: A total of 3230 pregnant underwent cesareansections. Of this total, 2,351 mother-newborn binomials (72.7%) were followed. When comparing infection events, considering the two different prophylaxis moments (before or after cord clamping), there was no statistical difference for SSI (X =1,98; p = 0.16) or neonatal sepsis (X = 0.94; p = 0.33). No analyzed variable was associated with maternal SSI. However, lower maternal age (p <0.003), lower gestational age (p <0.001), chorioamnionitis (p = 0.001), maternal hypertensive emergency (p < 0.001), centralization of blood flow (p = 0.02), ASA classification ≥ 3 (p = 0.02), dystocia or induction failure (p = 0.003) were significantly associated to neonatal sepsis. Only lower gestational age was significant in the multivariate analysis (p = 0.004). Conclusion: There was no negative impact on the clinical outcome of the newborn regarding the occurrence of sepsis. However, reduction in maternal SSI proportion was not observed and optimal time for antibiotic administration should be reevaluated.
Rapid Biodiesel Production From Palm Kernel Through In Situ Transesterification Reaction Using Cao As Catalyst

Current biodiesel production consist multiple step including extraction and purification oil which consuming 70% of the total production cost and also time consuming. In situ transesterification reaction process has been identified could simplified the biodiesel production. In situ transesterification is a process of producing alkyl ester directly from oil-bearing material which extraction and transesterification reaction proceeds in one single step, with the alcohol acting both as an extraction solvent and a transesterification reagent. This research studies the feasibility of CaO as a catalyst in the production of biodiesel through in situ transesterification reaction of palm kernel seed with methanol. Four parameters were investigated including seed particle size (1 and >1 mm), reaction time (2 – 4 h), catalyst amount (0.5; 1 and 1.5 g) and volume of methanol (100 – 400 mL). It was found that the concentration of biodiesel was affected by the parameters. Using 1 mm seed particle size, 3 h reaction time, 1 g catalyst weight and 200 mL methanol, the optimal concentration of biodiesel was reached. It can be concluded that CaO could facilitate in situ transesterification of palm kernel to biodiesel.

Pliocene and early Pleistocene carpofloras of Italy : methodological challenges and current progress

The fruits and seeds unearthed from Pliocene and Early Pleistocene deposits of Italy sum up to millions of specimens from over 50 sites, which have not yet been treated in a comprehensive way. To make all the information contained in these palaeofloras accessible, a monographic investigation similar to those published by Dieter Hans Mai and Harald Walther will be needed; including a very detailed taxonomic and nomenclatural framework. The present paper is the first step towards a monographic investigation of the Pliocene and Early Pleistocene floras of Italy, limited to a thorough taxonomic and nomenclatural revision of the carpological material of 19 species belonging to the Pinaceae (Picea florschuetzii, Pinus sylvestris subsp. pliocaenica), Betulaceae (Carpinus betulus subsp. 1, Corylus avellana), Cornaceae (Cornus maii sp. nov.), Eucommiaceae (Eucommia europaea), Fagaceae (Quercus cf. robur, Fagus deucalionis), Hamamelidaceae (Parrotia cf. persica, Parrotia reidiana), Hydrocharitaceae (Stratiotes intermedius), Juglandaceae (Carya globosa, Cyclocarya nucifera, Pterocarya limburgensis, Juglans bergomensis), Lamiaceae (Ajuga antiqua), Magnoliaceae (Liriodendron geminata), Menyanthaceae (Menyanthes trifoliata), and incertae sedis (Carpolites pliocucurbitinus nom. nov.). Several taxa inequivocally represent extinct species, often belonging to genera that disappeared from Europe. Other taxa, found to be morphologically very similar but not identical to modern European species, were either treated as extinct species or as fossil-subspecies of modern species. In various cases, the fossil record illustrates a morphological transition from the fruits and seeds of a fossil-taxon to those of a modern species. Only in two cases the fossil remains were considered identical to those of a modern species, since the morphology and its variation in the fossil assemblages were the same as that observed in several modern individuals and populations of that modern species. Finally, open nomenclature has been used for fossils with poorly diagnostic characters or represented by scarce material.
Informed Designers? Students’ Reflections on Their Engineering Design Process

Assessment of students‘ critical thinking and problem solving in engineering is a real challenge for classroom teachers and researchers. Yet, students demonstrate evidence of learning through multiple means, including written reflections. The purpose of this study was to explore how students in grades 5 and 7 reflect on what they had learned about engineering design practices in comparison to their previous understandings. The researchers applied qualitative content analysis to analyze student responses to engineering notebook prompts that asked students to reflect on their understanding of the problem and how to design solutions. Data were collected from two classrooms (n = 47) that had implemented integrated STEM curricula. The results of this study indicate that students were able to reflect meaningfully on their engineering practices and how their understanding of what it meant to design had changed. The notebooks provided an opportunity for students to demonstrate evidence of their learning through reflection on their own design practices. The findings suggest that teachers and curriculum developers can use reflection as a means to help students connect their own learning to informed design practices, which may help students move toward being independent informed designers. Future research should consider how teachers can use notebooks to provide feedback on engineering practices.
