description: We report the detection of thermal continuum radio emission from the K0 III coronal giant Pollux ($β$ Gem) with the Karl G. Jansky Very Large Array (VLA). The star was detected at 21 and 9 GHz with flux density values of $150\pm21$ and $43\pm8\,μ$Jy, respectively. We also place a $3σ_{\mathrm{rms}}$ upper limit of $23\,μ$Jy for the flux density at 3 GHz. We find the stellar disk-averaged brightness temperatures to be approximately 9500, 15000, and $<71000\,$K, at 21, 9, and 3 GHz, respectively, which are consistent with the values of the quiet Sun. The emission is most likely dominated by optically thick thermal emission from an upper chromosphere at 21 and 9 GHz. We discuss other possible additional sources of emission at all frequencies and show that there may also be a small contribution from gyroresonance emission above active regions, coronal free-free emission and free-free emission from an optically thin stellar wind, particularly at the lower frequencies. We constrain the maximum mass-loss rate from Pollux to be less than $3.7\times 10^{-11}\,M_{\odot}$ yr$^{-1}$ (assuming a wind terminal velocity of 215 km s$^{-1}$), which is about an order of magnitude smaller than previous constraints for coronal giants and is in agreement with existing predictions for the mass-loss rate of Pollux. These are the first detections of thermal radio emission from a single (i.e., non-binary) coronal giant and demonstrate that low activity coronal giants like Pollux have atmospheres at radio frequencies akin to the quiet Sun.

description: This paper discusses how to successfully digitize large-scale historical micro-data by augmenting optical character recognition (OCR) engines with pre- and post-processing methods. Although OCR software has improved dramatically in recent years due to improvements in machine learning, off-the-shelf OCR applications still present high error rates which limit their applications for accurate extraction of structured information. Complementing OCR with additional methods can however dramatically increase its success rate, making it a powerful and cost-efficient tool for economic historians. This paper showcases these methods and explains why they are useful. We apply them against two large balance sheet datasets and introduce quipucamayoc, a Python package containing these methods in a unified framework.

Writing in Public and Private: Southern White Women’s Personal Narratives of the American Civil War Era
Creators: name: Chen, Lai Wah
Publisher: name: University of Chicago
Year: 2022

description: When the violence of the American Civil War swept through the physical as well as the psychological landscape of the Confederate states, numerous men and women tried to capture the onslaught of death, destruction, and loss onto paper. At the time, the searing experiences of war inspired words to tumble into diaries and journals, and decades later, into the genre of memoirs and autobiographies as well. By the early 1900s, southern white women actively joined their male counterparts as authors in order to recount their experiences on the home front. White women writers, such as Louise Wigfall Wright, Mary Polk Branch, Sara Rice Pryor, and Marion Harland, married memory, history, and storytelling in order to publicly reshape their accounts about a personal as well as local and national past. These narrative revealed how southern white women leveraged their role as 'women' to make certain kinds of ideological claims about identity -- further complicated by their participation in a capitalistic print culture. Each woman utilized the genre of autobiography to project their own socio-political visions about gender, race, class, and nationalism in a public recount of theirs (and others') lived experiences.

description: The number of established X-chromosomal STR markers suitable for forensic usage has risen continuously during recent years. The observation of X-chromosomal transmission lines can significantly contribute to the solving of complex kinship cases. The highly polymorphic tetranucleotide markers DXS10079, DXS10074 and DXS10075 are located within a 280 kb region at Xq12 and provide stable haplotypes. Most of these haplotypes occur at low frequencies in the German population, which would qualify this marker cluster as a useful tool in pedigree analysis. For routine use it is necessary to investigate the allele structure and check for variations in the repeat flanking region in samples of different ethnic populations. The information on SNP occurrence may help to minimise pitfalls caused by partial primer mismatching. We sequenced a variety of samples from Germans, Asians and Africans with respect to different STR alleles. For all three marker systems SNPs were detected in the repeat flanking regions. Some alleles found in the marker systems DXS10074 and DXS10075 exhibited typical repeat structures and SNP patterns found only in Africans and differing from Germans and Asians. The highest SNP diversity for DXS10079 was present in samples of all three ethnic groups. Further population data are needed to confirm this observation.

description: Background: Inappropriate feeding practices and sub-optimal or no breastfeeding remains the greatest threat to child health and survival globally. Appropriate breastfeeding alone could save the lives of more than 3,500 children every day. Over two-third of deaths are often associated with inappropriate feeding practice occurring in the 1st year of life. Objective: The main objective of this study was to assess and describe feeding practices of infant and young children in predominantly food insecure communities. Methods: A cross-sectional study was conducted to assess the feeding practices of mothers of infants and young children 6-23 months. Dietary diversity, meal frequency, time of introduction to complementary feeding was used to measure optimal infant and young child feeding. And also household food security status measuring question were used to assess the food security status of the households. Result: Breastfeeding is universal in the study area. More than 95% of mothers reported breastfeeding at the time of the survey .Early initiation of breastfeeding is 67%. The majority of mothers 72.7% reported use of prelacteal feeding. More than 95% of mothers reported breast feeding at the time of the survey. The rate of exclusive breast feeding was only 12.4%. The majority of mothers (79 %) introduced complementary feeding too early, before six months of age. Minimum dietary diversity was 16% among infants 6-8 months and 27.7 % among those 9-23 months. Of the children 6-23 months of age 57.6% receive minimum recommended meal frequency. Optimal complementary feeding practice was identified in only 17.2%. Food insecurity with moderate and with severe hunger was 64.5% and 10.5%, respectively. Food insecurity was one of the factors that contributed to sub optimal feeding practice. Maternal education &antenatal care were factors related to infant and young child feeding practices. Conclusion: The prevalence of optimal infant and young child feeding practice was very low and household food security status was one of the factors related to optimal feeding practice. The rate of exclusive breastfeeding was very low. To reduce child morbidity and mortality of the infant and young child, the influence of maternal educational status and antenatal care provision should not be neglected .Integration of infant and young child feeding (IYCF) program with the other routine health service program is important to optimize the feeding practice and also to improve and maintain standard growth and development of the children

description: Medical ultrasound imaging relies heavily on high-quality signal processing to provide reliable and interpretable image reconstructions. Conventionally, reconstruction algorithms where derived from physical principles. These algorithms rely on assumptions and approximations of the underlying measurement model, limiting image quality in settings were these assumptions break down. Conversely, more sophisticated solutions based on statistical modelling, careful parameter tuning, or through increased model complexity, can be sensitive to different environments. Recently, deep learning based methods, which are optimized in a data-driven fashion, have gained popularity. These model-agnostic techniques often rely on generic model structures, and require vast training data to converge to a robust solution. A relatively new paradigm combines the power of the two: leveraging data-driven deep learning, as well as exploiting domain knowledge. These model-based solutions yield high robustness, and require less parameters and training data than conventional neural networks. In this work we provide an overview of these techniques from recent literature, and discuss a wide variety of ultrasound applications. We aim to inspire the reader to further research in this area, and to address the opportunities within the field of ultrasound signal processing. We conclude with a future perspective on model-based deep learning techniques for medical ultrasound.

description: The adoption of new bio-based technologies that reduce our reliance on fossil fuels is presented as a path to reduce greenhouse gas emissions while creating new business opportunities. Such a transition towards a bio-based economy will require substantial investments in technological innovations that will likely affect how value chains are structured and which actors benefit from this transformation. Yet, previous studies on the bioeconomy have largely ignored the relationship between the structure of value chains and the rate of technological innovation. In this article, we analyze the link between technological innovation, value chain structures, and welfare distribution in the transition to a bioeconomy. We find that an acceleration in the rate of bioeconomy innovation is associated with shorter and more vertically coordinated value chains, bigger firms with higher market shares, increasing knowledge-sharing among value chain members, and a leading role by firms with core research capabilities. Finally, we argue that while bio-based innovation can potentially achieve environmental sustainability, it creates risks for the weakest value chain actors. Thus, we propose some lines of thought regarding the potential distributional effects of bio-based innovation. From a policy perspective, this debate is relevant to safeguarding social sustainability in the transition to a bioeconomy.

description: Greenlees established an equivalence of categories between the homotopy category of rational SO(3)-spectra and the derived category DA(SO(3)) of a certain abelian category. In this paper we lift this equivalence of homotopy categories to the level of Quillen equivalences of model categories. Methods used in this paper provide the first step towards obtaining an algebraic model for the toral part of rational G-spectra, for any compact Lie group G.

description: Background: Scabies is an allergic response to an infestation of the skin by the scabies mite. Lymphadenopathy, acute post-streptococcal glomerulonephritis and rheumatic fever are complications related with scabies due to secondary bacterial infection. World health organization listed the problem as one of the neglected tropical diseases. Regional health bureau was notified about the outbreak on September 24/2016. Investigation and control activities were started on October 13/2016.The aim of the investigation was to identify source, control the outbreak and assess risk factors associated with it. Methods: We employed descriptive followed by unmatched case-control study design in a ratio of 1:2. Patients were recruited from temporary treatment sites. Controls were recruited from the nearby community by house to house visit and ensuring no scabies patient in the family. Additionally, line listing of cases was done to carry out descriptive analysis. Structured questionnaire was used to collect data. Result: Descriptive: The outbreak started in March and ended in October 2016. We line listed 1958 (males 1092 and females 866) patients with scabies. One thousand two hundred eighty eight (65%) were less than 15 years of age. Age ranged from 2 month to 84 years with median age of 12years. Overall attack rate was 4%. The outbreak affected 15 kebeles (Lowest government structure) from the total of 84. Analytical: We enrolled 100 cases and 200 controls. History of contact with a patient of scabies (P<0.00001) and age less than 18 years (P<0.0001) were among risk factors associated with the outbreak. Conclusion: Religious boarding school was implicated as a source of the outbreak. Community mobilized and outbreak controlled according to the guideline of scabies. We strongly recommend the regional health bureau to incorporate scabies surveillance in the integrated disease surveillance system of the region

description: We introduce a decision scheme for optimally choosing a classifier, which segments the cosmic web into different structure types (voids, sheets, filaments, and clusters). Our framework, based on information theory, accounts for the design aims of different classes of possible applications: (i) parameter inference, (ii) model selection, and (iii) prediction of new observations. As an illustration, we use cosmographic maps of web-types in the Sloan Digital Sky Survey to assess the relative performance of the classifiers T-web, DIVA and ORIGAMI for: (i) analyzing the morphology of the cosmic web, (ii) discriminating dark energy models, and (iii) predicting galaxy colors. Our study substantiates a data-supported connection between cosmic web analysis and information theory, and paves the path towards principled design of analysis procedures for the next generation of galaxy surveys. We have made the cosmic web maps, galaxy catalog, and analysis scripts used in this work publicly available.

description: The purpose of this study was to examine the expression profiles of a drug metabolizing enzyme cytochrome P450 (CYP) 3A62 mRNA in the intestine and liver of normal male Wistar rats, and its regional differences in the intestinal tract. Nine-week-old male rats were used, and their intestine were divided equally into nine segments. The expression patterns of CYP3A62 mRNA in the intestine and liver were examined using a reverse transcription-polymerase chain reaction (RT-PCR). The PCR products for CYP3A62 mRNA were readily detectable in the intestine of normal male rats, whereas no bands for CYP3A62 mRNA were detected in the liver using similar PCR conditions as those used in the intestine. The expression of CYP3A62 mRNA was found to be high in the jejunum, and stable until the bottom of the small intestine. Only the decreased expression pattern in the bottom of the intestine was contradictory to our previous findings on CYP3A9 and CYP3A18 mRNAs. Unlike other CYPs of the CYP3A subfamily, CYP3A62 was found to be predominant in the intestine rather than the liver of normal male Wistar rats. This suggests that CYP3A62 also has an important role in the detoxification of xenobiotics similar to endogenous substances as an absorptive barrier in the intestine. These findings may help the evaluation of gastrointestinal drug absorption and drug-drug interaction in rats.

description: Biofilms are ubiquitous macro-colonies of bacteria that develop at various interfaces (solid-liquid, solid-gas or liquid-gas). The formation of biofilms starts with the attachment of individual bacteria to an interface, where they proliferate and produce a slimy polymeric matrix - two processes that result in colony growth and spreading. Recent experiments on the growth of biofilms on agar substrates under air have shown that for certain bacterial strains, the production of the extracellular matrix and the resulting osmotic influx of nutrient-rich water from the agar into the biofilm are more crucial for the spreading behaviour of a biofilm than the motility of individual bacteria. We present a model which describes the biofilm evolution and the advancing biofilm edge for this spreading mechanism. The model is based on a gradient dynamics formulation for thin films of biologically passive liquid mixtures and suspensions, supplemented by bioactive processes which play a decisive role in the osmotic spreading of biofilms. It explicitly includes the wetting properties of the biofilm on the agar substrate via a disjoining pressure and can therefore give insight into the interplay between passive surface forces and bioactive growth processes.

On the radio dichotomy of active galactic nuclei

Year: 2016
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: It is still a mystery why only a small fraction of active galactic nuclei (AGNs) contain relativistic jets. Strong magnetic field is a necessary ingredient for jet formation, however, the advection of the external field in a geometrically thin disk is inefficient. The gas with a small angular velocity may fall from the Bondi radius $R_{\rm B}$ nearly freely to the circularization radius $R_{\rm c}$, and a thin accretion disk is formed within $R_{\rm c}$. We suggest that the external magnetic field is substantially enhanced in this region, and the magnetic field at $R_{\rm c}$ can be sufficiently strong to drive outflows from the disk if the angular velocity of the gas is low at $R_{\rm B}$. The magnetic field is efficiently dragged in the disk, because most angular momentum of the disk is removed by the outflows that leads to a significantly high radial velocity. The strong magnetic field formed in this way may accelerate jets in the region near the black hole either by the Blandford-Payne or/and Blandford-Znajek mechanisms. We suggest that the radio dichotomy of AGNs predominantly originates from the angular velocity of the circumnuclear gas. An AGN will appear as a radio-loud (RL) one if the angular velocity of the circumnuclear gas is lower than a critical value at the Bondi radius, otherwise, it will appear as a radio-quiet (RQ) AGN. This is supported by the observations that RL nuclei are invariably hosted by core galaxies. Our model suggests that the mass growth of the black holes in RL quasars is much faster than that in RQ quasars with the same luminosity, which is consistent with the fact that the massive black holes in RL quasars are systematically a few times heavier than those in their RQ counterparts.

description: Background - Ethiopia is one of the most populous countries in Africa where only less than 23% of women in the reproductive age group are currently using modern contraception. The objective of this study was to assess factors influencing the utilization of modern contraception among women in the reproductive age group in Angolela and Tera District of the North Shewa Administrative Zone in the Amhara National Regional State which is located 110 kms north of Addis Ababa. Design and Methods - This study was an institution based un-matched case-control study in which four health facilities were selected from the existing six health facilities in the district using the lottery method. The target population was women in the reproductive age group (15-49 years). Two hundred and eighty five registered modern contraceptive users (cases) from the selected four health facilities and the same number of women not using modern contraception (controls), visiting the same health facilities for reasons other than family planning service were taken by simple random sampling. Data analysis was done using chi-square test and logistic regression analysis. Results - Among the variables analyzed, respondents' age, marital status and average monthly income were the socio - economic and demographic variables that showed significant difference between the two study groups (p<0.05). Similarly, some sociopsychological and attitudinal questions like "modern contraception use helps a mother regain her strength before the next pregnancy"," modern contraception decreases sexual satisfaction"," Interspousal communication" and the sources of information about the various methods of contraception have revealed significant difference between the two study groups (p<0.05). On the other hand reproductive factors like history of still birth and abortion did not show statistically significant difference between the two study groups (p>0.05). Conclusions - It is concluded from this study that modern contraceptive utilization is vii associated with some socio-economic, socio-demographic and socio-psychological factors like age, marital status, average family monthly income and, spousal communication. It is also associated with different sources of information like mass media and Health institutions. Recommendations - Based on the findings of the study it is recommended to enhance planned IEC using mass media and health institutions and to improve household economic activities through the use of micro - finance institutions and rural banks.

description: 3,4-Dichloroaniline (DCA) showed an unusually high bioconcentration factor (BCF) up to 800 in the sediment dweller Lumbriculus variegatus, exceeding BCFs found in fish and other aquatic organisms by a factor of 8-40. In the scope of the European Risk Assessment process for different aromatic amines, concern was expressed with regards to biomagnification and secondary poisoning of man. Although measured BCF data in fish may be not critical, biomagnification in food chain of sediment, sediment dwelling organisms, fish eating birds or mammal (including man) can not be excluded. To address this issue, the concentration of DCA in fish due to dietary uptake via L. variegatus (i. e., the biomagnifications factor, BMF) was calculated, based on two different assumptions: 1) Either DCA is accumulated in L. variegatus in the form of a metabolite, but instantaneously released as DCA in fish, or 2) a DCA metabolite is accumulated in L. variegatus and further accumulated in fish. In the first case, application of an existing experimental kinetic model showed that the experimental BCF is likely to increase from 22 to approx. 25 if uptake via food has to be taken into account. In the second case, use of a physiology-based toxicokinetic model (PBTK) resulted in a BCF of 1.7 to 46 for the DCA metabolite. The daily uptake for a consumer, given in the European Union Risk Assessment Report for DCA, would rise by 0.6 to 1.3 %. These analyses demonstrate that biomagnifications via sediment organisms is an exposure route that deserves attention in environmental risk assessments. However, the bioconcentration factor established in sediment organisms may overestimate the threat for human beings. The use of PBTK modeling is proposed as a means of estimating the increased daily uptake for a consumer.

description: The cellular and molecular regulation of MAPKs and apoptosis was investigated in a model of hypoxiatolerance. Survival of neurons in Chrysemys picta bellii, an anoxia-tolerant turtle, involves a reduction in energy metabolism. The biochemical/physiological mechanisms of anoxia tolerance have been examined at the level of ion transport and ATP turnover. However, changes in the phosphorylation state of key enzymes and kinases, mainly, MAPKs, may occur during anoxia, thereby reversible protein phosphorylation could be a critical factor and major mechanism of metabolic reorganization for enduring anaerobiosis. If a turtle were to undergo hypoxia akin to that experienced in its native habitat, it was placed in a glass aquarium filled with water to within a half inch of the top. After the turtle was anesthetized, through extended hypoxia or anesthesia, the animal was sacrificed by decapitation. The brain was then excised and placed in anoxic artificial cerebrospinal fluid. Total protein extraction was performed by homogenizing brain in a buffer, followed by threonine and tyrosine phosphorylation determination of MAPKs, and caspase activity. MAPKp38 was decreased after reoxygenation following 1 day and 1 week hypoxia. The effect of hypoxia on the phosphorylation of MAPKERK was biphasic: Enhancement at 5h and inhibition at 6 weeks. Pro-caspases 8/9 were unchanged by hypoxia until increasing at 6 weeks. Both pro-caspases were upregulated by reoxygenation at 1 day or 6 weeks hypoxia. Neither hypoxia nor reoxygenation induced the cleavage of pro-caspases 8/9 into p20 and p10, respectively. Furthermore, hypoxia induced Bax at 3 days and 1 week, and reoxygenation increased Bax - 4-fold at 1 day. Although the expression of Bcl-2 was slightly increased by hypoxia, [Bcl-2] was 3-4-fold smaller in comparison with Bax. These results indicate that hypoxia up-regulates MAPKERK but not MAPKp38; hypoxia/reperfusion increases the expression of caspases and pro-apoptotic cofactors. The patterns of MAPK regulation suggest the significance of these kinases in cellular adaptation to oxygen deprivation with biomedical correlations, and thereby identify novel natural responsive signaling cofactors in Chrysemys picta bellii with potential pharmacologic and clinical applications.

description: The localization properties of one-dimensional degenerate Fermi gases with cavity-assisted non-local quasiperiodic interactions are numerically studied. Although the cavity-induced interaction is typically nonlocal, it is proved that the eigenstate thermalization hypothesis (ETH) is still applicable in our system depending on the system parameters. We also find the segment of the spectrum corresponding to infinite effective temperature varies for different system parameters, which indicates the spectral range employed in the spectral statistical analysis should be varied accordingly. The features of many-body localization (MBL) are numerically identified by analyzing the spectral statistics and the entanglement entropy using exact diagonalization. These features are further confirmed by our time evolution results. In addition, the number of cavity photons are found stable over long time dynamics in the MBL phase. Such a feature can not only be utilized to nondestructively diagnose the MBL phase by monitoring the number of leaking photons from the cavity, but leveraged for constructing a device to produce a stable number of photons.

description: Background: The use of substances such as caffeine, alcohol, cigarette, and khat during pregnancy can results in adverse health effects on the fetus. The World Health Organization (WHO) recommends a daily caffeine intake should not exceed 300 mg. Likewise, pregnant woman should avoid alcohol, khat and tobacco use. However, the magnitude of these substances use among pregnant women is not studied in developing countries such as Ethiopia. Objectives: The study aimed to determine the prevalence of excess daily caffeine consumption and its associated factors, prevalence of alcohol consumption, khat chewing, and tobacco use during pregnancy. Methods: A community based cross-sectional study was conducted from April 12-May 15, 2018 among 352 pregnant women. Stratified sampling technique was used to select pregnant women. Two days non-consecutive 24-hour recall was used to assess the self-reported daily caffeine intake. The collected data were compiled, checked, coded and entered using Epi-data version 3.1 software package and exported into Stata 14 for data management and analysis. Central tendency (median) and dispersion (range) were estimated for caffeine data. Prevalence were estimated for excess caffeine intake per day, alcohol consumption, khat chewing, passive tobacco smoking and overall substances use during pregnancy. Multivariate binary logistic regression was run to identify associated factors for excess caffeine intake among pregnant women. Results: A total of 341 pregnant women were interviewed. The median age of pregnant women was 28 (IQR=6). The median daily caffeine intake among pregnant women was 170.5 mg (IQR=135.1) and ranged from 0.0 to 548.9mg per day. About 17.6% (95% CI: 13.9%, 22.0%) of the pregnant women consumed 300 mg and above caffeine per day. About 10.0% (95% CI: 7.2%, 13.7%) of the pregnant women consumed alcohol during current pregnancy. About 35.8% (95% CI: 30.8, 41.0%) of the pregnant women chewed khat during current pregnancy. None of the pregnant women were active tobacco smoker. However, 23.2 % (95% xii CI: 19.0, 28.0%) of pregnant women were passive smokers. The prevalence of at least one substance use among pregnant women was 60.1 % (95% CI: 54.8%, 65.2%). The richest wealth status (AOR=3.66; 95% CI: 1.13, 11.88), and first trimester of pregnancy (AOR=4.04; 95% CI: 1.26, 13.05) were significantly associated factors for increased excessive caffeine consumption per day among pregnant women. Conclusions and Recommendation: In conclusion, the magnitude of substances use such as excess caffeine, khat chewing and passive tobacco smoking were high among pregnant women in Butajira, South Central Ethiopia. Therefore, interventional programs that address caffeine and alcohol consumption, khat chewing and tobacco smoke exposure among pregnant women is wanted.

description: Adrenaline has been shown to modulate proliferation of mouse fibroblasts, adventitial fibroblasts and synovial B (fibroblasts-like) cells. However, little is known about the response of cultured human hypertrophic scar fibroblasts to adrenaline. In this study, we investigated cell proliferation and involved mechanisms in hypertrophic scar fibroblasts in response to adrenaline. Population doubling time (PDT) assay and MTT assay were performed to determine the cell proliferation and cell viability, respectively. The expression of bFGF and TGF- ß1 was measured by reverse transcriptase-polymerase chain reaction (RT-PCR) and enzyme linked immunosorbent assay (ELISA). The results showed that adrenaline inhibited proliferation of normal and hypertrophic scar fibroblasts in a dose-dependent manner. Moreover, adrenaline up-regulated the expression of bFGF and down-regulated the expression of TGF- ß1 in normal and hypertrophic scar fibroblasts. Interestingly incubation with the a receptor antagonist regitine indicated that adrenaline mediated inhibition of cell proliferation and regulation of TGF-ß1 and bFGF in cultured normal and hypertrophic scar fibroblasts were mediated by the a receptor. These studies suggest that adrenaline inhibits proliferation and alters the expression of TGF-ß1 and bFGF in human hypertrophic scar fibroblast involving an a receptor mediated pathway.

description: We present ALMA 1.3 mm continuum, 12CO, C18O, and SO data for the Class 0 protostars, Lupus 3 MMS, IRAS 15398-3559, and IRAS 16253-2429 at resolutions of ~100 AU. By measuring a rotational profile in C18O, a 100 AU Keplerian disk around a 0.3 Msun protostar is observed in Lupus 3 MMS. No 100 AU Keplerian disks are observed in IRAS 15398-3559 and IRAS 16253-2429. Nevertheless, embedded compact (<30 AU) continuum components are detected. The C18O emission in IRAS 15398-3559 shows signatures of infall with a constant angular momentum. IRAS 16253-2429 exhibits signatures of infall and rotation, but its rotational profile is unresolved. By fitting the C18O data with our kinematic models, the protostellar masses and the disk radii are inferred to be 0.01 Msun and 20 AU in IRAS 15398-3559, and 0.03 Msun and 6 AU in IRAS 16253-2429. By comparing the specific angular momentum profiles from 10,000 to 100 AU in 8 Class 0 and I protostars, we find that the evolution of envelope rotation can be described with conventional inside-out collapse models. In comparison with a sample of 18 protostars with known disk radii, our results reveal signs of disk growth, with the disk radius increasing as M*^{0.8+/-0.14} or t^{1.09+\-0.37} in the Class 0 stage, where M* is the protostellar mass and t is the age. The disk growth rate slows down in the Class I stage. Besides, we find a hint that the mass accretion rate declines as t^{-0.26+\-0.04} from the Class 0 to I stages.

description: The deep sea survivability and biofouling characteristics of corrosion-resistant bulk carbon nanotubes (CNTs) have been studied after deployment in the Atlantic Ocean over the course of 12 months. Quantification of barnacle count, biofouling density, and non-combustible residue shows cyanoacrylate coatings increase durability and reduce the colonization of biofouling compared to as-received CNTs. Scanning electron microscopy was performed on the biofouled CNTs, and the majority of species were identified as diatoms, consisting of an ordered silica cell wall. Both the as-received and cyanoacrylate-treated CNTs were successfully acid purified to remove biogrowth, leading to complete recovery of tensile strength and electrical transport properties. Thermogravimetric analysis, scanning electron microscopy, contact angle, dynamic mechanical analysis, and current carrying capacity measurements validated the refunctionalization results. Thus, the multifunctional property recovery and enhanced durability confirms that CNTs are electrochemically stable in saltwater environments and are resilient to biofouling conditions in real-world environments after extended exposure.

description: Τελευταία, έχει παρατηρηθεί ότι έργα που έχουν δημιουργηθεί πριν από χρόνια, με χρήση οπλισμένου σκυροδέματος έχουν αρχίσει να παρουσιάζουν φθορές, και σταδιακά χάνουν την χρησιμότητά τους. Αυτό δεν συνεπάγεται ότι είναι από λειτουργικής άποψης ανεπαρκή, ή ότι έχουν επηρεαστεί από εξωτερικές μηχανικές δράσεις, αλλά βάσει της φυσικής ροής των πραγμάτων έχουν παλιώσει. Ως εκ τούτου, το ζήτημα της ανθεκτικότητας του οπλισμένου σκυροδέματος πρέπει να διευθετηθεί από τους πολιτικούς μηχανικούς, μια κατάσταση που κατά κύριο λόγο είναι απόρροια των μηχανισμών διάβρωσης. Πρόκειται για ένα φαινόμενο πολύπλοκο και συχνά μη προβλέψιμο, αφού αιτία διάβρωσης των υλικών (σκυρόδεμα, χάλυβας κ.α.) είναι πολλοί παράγοντες. Επίσης, σημαντική παράμετρος που μπορεί να ασκήσει επιρροή επί της στατικής επάρκειας μιας κατασκευής οπλισμένου σκυροδέματος είναι η εκδήλωση πυρκαγιών. Ωστόσο, η φωτιά δεν είναι ικανή να προκαλέσει αυτοτελώς καταστροφές επί του οπλισμένου σκυροδέματος. Σημειώνεται, πως δεν είναι εφικτός ο ακριβής υπολογισμός των επιδράσεων μιας πυρκαγιάς σ’ αυτού του τύπου τις κατασκευές, κι έτσι η αντιμετώπιση γίνεται εμπειρικά. Απώτερος σκοπός της παρούσας εργασίας είναι να αναλυθούν διεξοδικά τα παραπάνω φαινόμενα. Πιο αναλυτικά, στην αρχή θα γίνει παρουσίαση του τρόπου με τον οποίο παρασκευάζεται το οπλισμένο σκυρόδεμα. Ακολούθως, θα αναλυθεί πώς η ενανθράκωση και τα χλωριόντα αντιμετωπίζουν θετικά τα φαινόμενα διάβρωσης. Επίσης, θα περιγραφεί ο τρόπος δημιουργίας της διάβρωσης οπλισμού (οικονομικές επιπτώσεις, παράγοντες επίδρασης, μορφές διάβρωσης, ατμοσφαιρική διάβρωση κ.λπ.), και θα αναλυθεί το πώς επιδρά η πυρκαγιά σε κατασκευές οπλισμένου σκυροδέματος (ιδιότητες υλικών, συμπεριφορά δομικών στοιχείων, ζημιές, αίτια βλαβών στον φέροντα οργανισμό). Εν συνεχεία, θα προταθούν μέτρα, που κρίνεται σκόπιμο να ληφθούν εκ των προτέρων, αλλά και εκ των υστέρων, προς αντιμετώπιση των παραπάνω φαινομένων. Τέλος, θα γίνει καταγραφή των γενικών συμπερασμάτων.

description: Nu kunstmatige intelligentie steeds meer toepassingen krijgt en robots een serieuze factor op de werkvloer worden, zal tegelijkertijd de behoefte aan specifiek menselijke vaardigheden zoals creativiteit en verbeeldingskracht toenemen. Enerzijds is er een vraag naar goed opgeleide mensen in de technische vakken, anderzijds zijn nieuwsgierigheid en duiding belangrijke onderliggende waarden van innovatie. De snelle technologisering heeft een keerzijde. Mensen willen inzicht hebben in wat ze doen en gebruiken. Maken, vakmanschap en ambacht staan daardoor in een hernieuwde belangstelling.
