Survey of Cold Water Lines in Protoplanetary Disks: Indications of Systematic Volatile Depletion

We performed very deep searches for 2 ground-state water transitions in 13 protoplanetary disks with the HIFI instrument on board the Herschel Space Observatory, with integration times up to 12 hr per line. We also searched for, with shallower integrations, two other water transitions that sample warmer gas. The detection rate is low, and the upper limits provided by the observations are generally much lower than predictions of thermo-chemical models with canonical inputs. One ground-state transition is newly detected in the stacked spectrum of AA Tau, DM Tau, LkCa 15, and MWC 480. We run a grid of models to show that the abundance of gas-phase oxygen needs to be reduced by a factor of at least to be consistent with the observational upper limits (and positive detections) if a dust-to-gas mass ratio of 0.01 were to be assumed. As a continuation of previous ideas, we propose that the underlying reason for the depletion of oxygen (hence the low detection rate) is the freeze-out of volatiles such as water and CO onto dust grains followed by grain growth and settling/migration, which permanently removes these gas-phase molecules from the emissive upper layers of the outer disk. Such depletion of volatiles is likely ubiquitous among different disks, though not necessarily to the same degree. The volatiles might be returned back to the gas phase in the inner disk ( au), which is consistent with current constraints. Comparison with studies on disk dispersal due to photoevaporation indicates that the timescale for volatile depletion is shorter than that of photoevaporation.

From stabilitas loci to mobilitas loci: networked mobility and the transformation of place

Place is a much maligned notion within contemporary critical discourse. It is criticised for its lack of definitional precision; it is linked to strategies of exclusion; it is seen as marginal to modernist considerations of time and space; and with the emergence of cyberspace and virtual community, it is said to be left behind or reduced to the status of metaphor. Yet, place is a resilient notion and persists in the face of all these continuing challenges.
Educational results from blended learning: Using an educational platform in teaching Economics

This research investigates the learning result of applying blended learning with the combined use of open educational platform and traditional teaching. This educational intervention took place during the course Principles of Economic Theory in the 3rd grade of High School. We measured the differences in student performance in an assessment test before and after the educational intervention, but also the changes in their attitude as to the course of the economy, itself. Moreover, we evaluated the students’ satisfaction from using the open educational platform, but also the social presence which was created. The results led to the conclusion that hybrid teaching methods, can be used in the teaching of Economics and is considered as important as traditional ones.
BAT AGN Spectroscopic Survey. I. Spectral Measurements, Derived Quantities, and AGN Demographics

We present the first catalog and data release of the Swift-BAT AGN Spectroscopic Survey. We analyze optical spectra of the majority of the detected AGNs (77%, 642/836)based on their 14–195 keV emission in the 70-month Swift-BAT all-sky catalog. This includes redshift determination, absorption and emission-line measurements, and black hole mass and accretion rate estimates for the majority of obscured and unobscured AGNs (74%, 473/642), with 340 measured for the first time. With ∼90% of sources at , the survey represents a significant advance in the census of hard X-ray-selected AGNs in the local universe. In this first catalog paper, we describe the spectroscopic observations and data sets, and our initial spectral analysis. The FWHMs of the emission lines show broad agreement with the X-ray obscuration (∼94%), such that Sy 1–1.8 have cm−2, and Seyfert 2 have cm−2. Seyfert 1.9, however, show a range of column densities. Compared to narrow-line AGNs in the SDSS, the X-ray-selected AGNs have a larger fraction of dusty host galaxies ( ), suggesting that these types of AGN are missed in optical surveys. Using the [O iii] λ5007/Hβ and [N ii] λ6583/Hα emission-line diagnostic, about half of the sources are classified as Seyferts; ∼15% reside in dusty galaxies that lack an Hβ detection, but for which the upper limits on line emission imply either a Seyfert or LINER, are in galaxies with weak or no emission lines despite high-quality spectra, and a few percent each are LINERS, composite galaxies, H ii regions, or in known beamed AGNs.
Testing the initial-final mass relationship of white dwarfs

In this contribution we revisit the initial-final mass relationship of white dwarfs, which links the mass of a white dwarf with that of its progenitor in the main-sequence. Although this function is of paramount importance to several fields in modern astrophysics, it is still not well constrained either from the theoretical or the observational points of view. We present here a revision of the present semi-empirical initial-final mass relationship using all the available data and including our recent results obtained from studying white dwarfs in common proper motion pairs. We have also analyzed the results obtained so far to provide some clues on the dependence of this relationship on metallicity. Finally, we have also performed an indirect test of the initial-final mass relationship by studying its effect on the luminosity function and on the mass distribution of white dwarfs.
On a theta product formula for the symmetric A-type connection function

In this note we are concerned about a formula which gives a product expression for a sum of theta rational functions. This sum has already appeared in the connection formulae among symmetric A-type Jackson integrals (See [1], [2]). Let qeC, \q\ where (u)^ =ΠJ°=O(1 -q u). Let α1,α2, , αn, /? , y and y' be complex numbers such that aj = oiί-\-(j—1)(/ — y) and y 4-y' — 1.

The relationship between undergraduate education system and postgraduate achievement in statistics

The present study focuses on the relationship between undergraduate education system and the students’ achievement in statistics. The data was collected from 34 master students in Management Sciences who took an “inferential statistics” course. The history of their past education (long distance vs traditional), the type of exam questions and their mark on “inferential statistics” course were the important variables studied. The results showed a significant difference in achievements between those with long distance undergraduate education and those with traditional system (P<0.05). After doing analysis of covariance, using the pre-term evaluation mark, it still showed a significant difference between statistics achievement in two groups (P<0.05).
The Effect of Forage Harvest Date and Inoculation on the Yield and Fermentation Characteristics of Narrow-Leaved Lupin ( Lupinus angustifolius ) when Ensiled as a Whole Crop

A experiment was conducted during seasons of the year 2005, 2006 and 2007 to evaluate the effects of the stage of maturity and inoculant application on the fermentation quality of silage produced from narrow leaved lupin. The trial was carried out on the experimental farm in Gorzyn, belonging to Poznan University of Life Sciences (520 33’53 N, 150 53’42 E) in central part of Europe in Poland. A two-factor field experiment was carried out on narrow-leaved lupin cv. Zeus. The first factor was the green forage harvest dates (Cut 1 - at the flat pod stage, Cut 2 – at the stage of green ripe seeds), the other factor – silage inoculants: biological (strains of lactic acid bacteria), chemical (a mixture of organic acids) and a control object without inoculants. The silage raw material was closed in mini-silos for 10 weeks. The crops had a fresh matter yield from 15.8 to 30.8 t ha-1 corresponding to a dry matter yield from 2.2 to 8.8 t ha-1. The dry matter content in unwilted forage per kilogram ranged from 178.8 to 233.8 g. 24-hour wilting caused an increase in dry matter content from 205.5 to 349.5 g kg-1. Both inoculates improved the quality of silages, because they increased the number of lactic acid bacteria and decreased the number of unfavourable groups of bacteria. The narrow-leaved lupin can be used as a silage raw material, but before ensilage plants should be wilted and silage inoculants should be applied.
Searching for the Lost Sheep (Matthew 18: 10–14): Do Sensing Types and Intuitive Types Find Different Things?

ABSTRACT Drawing on psychological type theory and a reader-perspective approach to biblical hermeneutics, this study examines how sensing types and intuitive types read the Matthean reference to the lost sheep in different ways. Data drawn from a workshop involving 22 Anglican clergy (first year curates and training incumbents) illustrate how sensing types focus on important details in the passage, while intuitive types allow the passage to spark multiple ideas. While looking for the same lost sheep, sensing types and intuitive types are inclined to find different things and to preach different messages.
Title BDNF-dependent synaptic plasticity is suppressed by IL-1 β via p 38 MAPK Permalink

Evolving evidence suggests that brain inflammation and the buildup of proinflammatory cytokines increases the risk for cognitive decline and cognitive dysfunction. Interleukin-1β (IL-1β), acting via poorly understood mechanisms, appears to be a key cytokine in causing these deleterious effects along with a presumably related loss of LTP-type synaptic plasticity. We hypothesized that IL-1β disrupts BDNF signaling cascades and thereby impairs the formation of filamentous actin (F-actin) in dendritic spines, an event that is essential for the stabilization of LTP. Actin polymerization in spines requires phosphorylation of the filament severing protein cofilin and is modulated by expression of the immediate early gene product Arc. Using rat organotypic hippocampal cultures, we found that IL-1β suppressed BDNF-dependent regulation of Arc and phosphorylation of cofilin and CREB, a transcription factor regulating Arc expression. IL-1β appears to act on BDNF signal transduction by impairing the phosphorylation of insulin receptor substrate 1 (IRS-1), a protein which couples activation of the BDNF receptor TrkB to downstream signaling pathways regulating CREB, Arc, and cofilin. IL-1β upregulated p38 MAPK, and inhibiting p38 MAPK prevented IL-1β from disrupting BDNF signaling. IL-1β also prevented the formation of F-actin in spines and impaired the consolidation, but not induction, of BDNFdependent LTP in acute hippocampal slices. The suppressive effect of IL-1β on F-actin and LTP was prevented by inhibiting p38 MAPK. These findings define a new mechanism for the action of IL-1β on LTP and point to a potential therapeutic target to restore synaptic plasticity.
User Association and Load Balancing for Massive MIMO through Deep Learning

This work investigates the use of deep learning to perform user-cell association for sum-rate maximization in Massive MIMO networks. It is shown how a deep neural network can be trained to approach the optimal association rule with a much more limited computational complexity, thus enabling to update the association rule in real-time, on the basis of the mobility patterns of users. In particular, the proposed neural network design requires as input only the users’ geographical positions. Numerical results show that it guarantees the same performance of traditional optimization-oriented methods.
Seasonal Variation of the Intraepithelial Gland in Camel Epididymis with Special Reference to Autophagosome

Abstract The key role of the epididymis is contributing to sperm storage, maturation, and survival. The epididymis of camel has a unique structure called the intraepithelial gland. The present work aimed to investigate the structure of the epididymal intraepithelial gland with special references to the seasonal variation. The samples were collected from the distal part of the corpus epididymes of completely healthy mature camels (Camelus dromedarius) in the breeding and nonbreeding seasons. Tomato lectin-positive material had been demonstrated within the epididymal spermatozoa. Here, we provide the first transmission electron microscopic study for the intraepithelial gland of camel epididymis detecting the autophagy during the nonbreeding season. The autophagosomes originated from the endoplasmic reticulum, surrounding mitochondria, and located mainly next to the basement membrane. This location is probably valuable for subsequent passing of their contents into the interstitium for possible recycling. The histochemical and ultrastructural characteristics of the gland in the breeding season indicated a hyperactive secretory microenvironment enriched with the glycoprotein-producing machinery, which could be controlled by androgens. The present data suggest that the camel intraepithelial gland has a significant impact on the reproductive activity through their secretory microenvironment during the breeding season. Moreover, it recycles the unused organelles or proteins for reuse or to supply energy under stress conditions in the nonbreeding season.
Novel Role of MBL/MASP-2 in Neuronal Autoimmunity and NeuroAIDS

Human immunodeficiency virus-1 (HIV-1) is a life- threatening virus which disrupts host immune system, and about half of the HIV-1 infected individuals develop neurocognitive impairment in brain. Neuronal autoimmunity is also observed in patients with HIV-1 infection, resulting in inflammation and damage in neurons and axons. Mannose binding lectin, MBL, plays important role in HIV by its direct binding of gp120, envelope protein present on the surface of HIV-1through lectin mediated complement activation pathway. MBL is also associated with initiation of autoimmunity due to its involvement in clearance of apoptotic cells. This study focuses on determining the role of MBL mediated complement pathway in the induction of neuronal autoimmunity during HIV-1 infection of the brain. Overall, higher MBL/gp120 immune complex deposition, and MBL/gp120 interaction with axonal damage marker amyloid precursor protein (APP) in HIV encephalitis (HIVE) brain suggest MBL mediated neuroinflammation and neuronal damage in HIVE. Increased immunoreactivitv of MBL/gp120 immune complex with myelin oligodendrocyte glycoprotein (MOG), and myelin basic protein (MBP) suggest that these interactions potentially damage oligodendrocytes and interfere with myelination in HIVE. Increased deposition of MBL mediated immune complexes (C3d,C5b9,IgG) in HIVE suggests that deposition of these aggregates may play a key role in axonal damage, demyelination and neuroinflammation in HIV encephalitis. Presence of C4, C5, and MBL autoantibodies and higher inflammatory cytokine response (IL-1[beta], IL-6, IL-2, and IL-8, Rantes,MIP- 1[beta]2, and MCP-1)in the cerebrospinal fluid (CSF) of HIV-1 infected individuals with neurocognitive impairment suggests that presence of MBL autoantibodies is associated with proinflammatory cytokine immune response in HIV-1 related CNS impairment
Changes in blood parameters of endurance horses in 30-km training.

Eight endurance horses registered for competition in different categories of Sultan Cup Endurance Ride, in November 2009 were selected for an evaluation of the soundness of the horses and an examination of the changes of blood parameters in training prior to the competition. Three blood samples were taken from each horse: pre-ride, immediate post ride and 24 hours post-ride. All horses were trained at 30 km and departed at the same time and tested on the same track. Blood samples were evaluated for both haematology and biochemistry components: red blood cell (RBC), packed cell volume (PCV), white blood cell (WBC), segmented neutrophil, lymphocyte counts, electrolytes concentration, total protein (TP), aspartate aminotransferase (AST), creatine kinase (CK) and lactate. One horse was diagnosed with exertional rhabdomyolysis post-training and was removed from statistical analysis. In this study, the significant changes in most blood parameters indicated that the 30-km endurance training induced some physiological responses in horses with minimal stress and loss of water and electrolytes as reflected in the changes of blood parameters. Although elevation in serum muscle enzymes and lactate was significant, it was believed to be a normal physiological response of horses towards training without noticeable muscle injuries and/or metabolic acidosis.
Processing of Lexical Bundles by Persian Speaking Learners of English

Formulaic sequence (FS) is a general term often used to refer to various types of recurrent clusters. One particular type of FSs common in different registers is lexical bundles (LBs). This study investigated whether LBs are stored and processed as a whole in the mind of language users and whether their functional discourse type has any effect on their processing. To serve these objectives, three self-paced reading experiments were set out using the DMDX computer program. The stimuli consisted of target constituents containing LBs (discourse organizers and referential bundles) and control constituents containing non-lexical bundles (NLBs). Ninety intermediate Iranian EFL learners were selected and assigned to three groups randomly. Participants were asked to read each stimulus and answer the question that followed. The stimuli were presented word-by-word, portion-by-portion, and sentence-by-sentence in three experiments. The results showed no significant difference between LBs and NLBs in all three experiments, meaning that LBs are not stored and processed as a whole in the mind of language users In addition, participants read referential bundles significantly faster than discourse organizers in the word-by-word experiment.
Omega-3 fatty acids in schizophrenia Part II: Clinical applications

Abstract Ω-3 unsaturated fatty acids are compounds belonging to the group of essential fatty acids (EFAs). The history of the discovery of EFAs dates back to the 1930s of the twentieth century, however, growing interest in ω-3 EFAs in the context of mental health has been observed since the year 2000. In view of their multidirectional action, these compounds are a promising form of adjunctive therapy of many illnesses, including psychiatric disorders. The present article aims to review the literature on the clinical applicability of ω-3 EFAs in treating schizophrenia. We present the results of preclinical studies in this area and the mechanisms of ω-3 EFAs action discussed by the authors. The randomized controlled trials (RCTs) evaluating the possibility of using ω-3 EFAs in schizophrenia are characterized in detail. The results of the tests are not clear, which may result from the methodological diversity of interventions made. Ω-3 EFAs seem to be a promising form of adjunctive therapy of schizophrenia. Further research is needed, which will allow for defining groups of patients in which intervention will bring the expected results.
Africa and Technology in Higher Education: Trends, Challenges, and Promise

Showing that technology in higher education in African countries is lagging behind the developed world and also that Internet connectivity is on the rise in African nations, this paper describes and analyzes trends in the use of ICTs as well as the impact that the shortage in technological use and capacity has on Africa, particularly that needed to address the changing demands within the higher education sector. Challenges to the proposed widespread implementation of technology exist, particularly because most institutions of higher education have very limited technological capacity and basic resources, such as electricity, equipment, and funding; brain drain, improper use of ICT, and the colonial mindset are also factors. It is suggested that ICT be integrated into education with a purpose and within the context of postcolonial theory and a critical pedagogy perspective. Key uses of ICT in education, including mobile technology, are access, support, and communication, making learning available to anyone anywhere and enhancing learning as an interactive process, with much potential for collaboration and problem-solving. Four salient components related to incorporating ICTs into higher education are discussed: (a) teacher education; (b) curriculum; (c) distance learning; and (d) educational policy, planning, and management. Examples of technological initiatives in higher education as well as recommendations are given. Ghana, Kenya, and Tanzania, representative of other African nations to varying degrees, are highlighted in regard to ICT infrastructure and its relevancy to higher education. It is concluded that African higher education has high potential for catching up in the technological race.
FDI Trends, Pull Factors and Policies in Thailand

The objective of the research is to investigate the pull factors that have impacted on FDI inflows in Thailand. It seeks to explain the decline of inward FDI in Thailand over recent years, in light of competition from inward FDI into Southeast Asia countries. The study uses empirical exploratory data analysis to examine the inward pull factor in Thailand compared to neighbouring countries in ASEAN which are: Indonesia, Malaysia, Singapore, and Vietnam, covering the period from 2004 to 2015. The main pull factors derived from the literature findings include: labour cost, infrastructure quality, institutions, FDI restrictions, and tax rates. The results of the research show that Thailand has lost competitiveness on labour cost, infrastructure quality, political stability, while FDI restrictions seems play some role in attracting FDI and it was not the case with tax rates.
