Improved sizing of soot primary particles using mass-mobility measurements

ABSTRACT The properties and impacts of aggregated aerosol particles (i.e., soot, metal oxide fumes) depend on their morphology, as characterized by fractal dimension, prefactor, and primary particle diameter. The morphology may be measured directly by time-consuming ex situ microscopy or rapid but indirect in situ methods. Previously, it was found that particle mass and mobility measurements could be used for the estimation of the primary particle diameter of zirconia aggregates, using plausible assumptions related to the fractal structure (specifically, prefactor and exponent ). Since the formation and growth of zirconia aggregates are different from carbon soot, here we compare primary particle diameters measured directly from transmission electron microscopy analysis of soot particles with the diameters estimated from mass–mobility measurements. Performing extensive measurements on soot emissions from two reciprocating engines over a range of operating conditions, we found that there are no universal values of and that can be used for all conditions. However, new optimized values of and are estimated here for soot particles. The variation of the primary particle diameter with particle size is also taken into consideration and is shown to be essential to obtain physically realistic results. Using optimized values of and , the average primary particle sizing error is reduced for all soot types. This suggests that with some calibration, in situ sizing of the primary particle diameter, using mass and mobility measurements, can provide useful accuracy.

Elementary school students’ attitudes towards peers with disabilities: The role of personal and contextual factors

ABSTRACT Background: Attitudes of classmates has been considered as one of the major problems in inclusive education, negatively influencing the participation of students with disability in school contexts. The goal of this study was to examine Italian typically developing children's attitudes towards their peers with disabilities. Method: In a sample of 560 elementary school students aged 6 - 11 years old we tested - through multiple regression analysis - the impact of personal and contextual factors, such as sex and age of participants, type of disability of peers with disabilities, experience with peers with disabilities and, in particular, the type of presentation of students with disabilities on attitudes of elementary school students without disability. Results: Results showed that girls and younger students generally hold more positive attitudes towards peers with disabilities. Less accepting attitudes towards peers with behaviour problems than those with intellectual or sensory disabilities were also found. Experience with peers with disabilities in class was not related to attitudes towards disabilities; instead, providing a positive presentation of peers with disabilities associated with their strengths positively impacted attitudes towards disabilities, regardless of sex and age of participants and type of disability of peers. Conclusions: The results of our study suggested the impact of the type of information provided to students about disabilities on their attitudes. Particular emphasis should be given to the way in which children with disabilities are presented to typically developing classmates, and information provided should stimulate a positive image of peers with disabilities.
Anadara granosa shell powder improves the metabolism, testosterone level, and sound frequency of Pelung chickens

Background and Aim: Pelung chickens make unique, pleasant, and rhythmic sounds in addition to having strong muscle mass. Performance is controlled by testosterone. A natural aromatase blocker is an agent capable of blocking the aromatase enzyme, which consequently prevents testosterone from being changed into estradiol. Such a condition results in consistently high testosterone levels. The aim of this study was to determine the effect of the administration of the shell powder of Anadara granosa on the testosterone level, frequency and quality of sounds, and metabolism of Pelung chickens within set parameters of thyroid hormone levels, the triiodothyronine (T3)/thyroxine (T4) ratio, and weight gain. Materials and Methods: This study used four Pelung chickens aged 14 months. Control data consisted of data before treatment (day 0). Shell powder of A. granosa was administered for 56 days. Body weight (BW) was measured, and blood samples were drawn. In addition, the sounds from Pelung chickens were recorded once every 2 weeks on days 14, 28, 42, and 56. The blood samples were analyzed using the enzyme immunoassay method to determine testosterone, T3, and T4 levels. The sounds of Pelung chickens were recorded using the Hagemon touch method and analyzed using the Audacity application. Results: The results showed a significant difference (p<0.05) in the levels of testosterone, BW, and sound frequency after the administration of A. granosa shell powder, but the administration did not have a significant effect on the levels of T4 and T3 hormones (thyroid hormone), T3/T4 ratio, or sound duration. The testosterone content and BW of Pelung chickens increased from day 14 to day 56, whereas T3 was indicative of the same profile as the T4 hormone. However, T3 and T4 levels and the T3/T4 ratio decreased and increased, respectively. The sound frequency of Pelung chickens increased from day 0 to day 14, although sound duration decreased. Conclusion: The administration of A. granosa shell powder at 0.9 mg/kg BW orally could improve the metabolism, testosterone level, BW, and sound frequency of Pelung chickens.
UNINTELLIGIBLE SPEECH: LISTENERS' AWARENESS TO INDONESIAN-ACCENTED SPEECH WITH PRONUNCIATION ERRORS

There have been widely exposed researches that analyze accented and intelligible speech of foreign language; yet, the study concerning listeners' awareness of the pronunciation errors is hardly found. Therefore, the current study aims to find out segmental features and the source of errors that have caused unintelligible speech of Indonesian-accented speech and describe the listeners' awareness of the errors. This descriptive qualitative research investigates listeners' transcripts of Indonesian-accented speeches through purposive sampling. The standard orthography transcripts are then transformed into phonemic transcripts. They are analyzed by error analysis based on phonological operation by Davenport and Hannahs. The result is further checked by the listeners to generate their awareness of the errors through interviews. There are consonants causing unintelligibility more than vowels. Furthermore, it is found that there are six pronunciation features affecting listeners' awareness of speakers' pronunciation errors: 1) aspiration, 2) spelling system, 3) blended phonemes, 4) absent phonemes, 5) different articulation, and 6) homophone in the research.
Inter and Intra-Rater Reliability of Measuring Photometric Craniovertebral Angle Using a Cloud-Based Video Communication Platform

Objective: Due to social distancing guidelines during the Coronavirus (COVID-19) pandemic, most providers and patients have wanted to avoid close contact. This makes physical therapy (PT) assessments difficult because of the lack of empirical evidence about the reliability of various clinical measurements performed in a virtual environment. One such procedure is the photometric measurement of craniovertebral (CV) angle. Craniovertebral angle measurement is usually performed in an outpatient setting and is defined as the acute angle formed between a straight line connecting the spinous process of C7 to the tragus of the ear, and the horizontal line passing through the spinous process of the C7. Although the photometric measurement of CV angles is considered both valid and reliable in the clinics, no empirical evidence exists about the CV angle measurement reliability when performed in a virtual environment. Thus, the purpose of this study was to assess the inter- and intra-rater reliability of photometric CV angle measurement using a cloud-based video communication platform. Number of Subjects: 66 subjects (57 females). Methods: All measurements were performed by two final year PT students who had completed the musculoskeletal part of the curriculum and were blinded to each other's measurements. Each subject was photographed in two postures over a HIPAA-compliant video-based telehealth platform: (1) normal/relaxed posture and (2) ideal posture (posture the subject considered good). Student researcher 1 measured the CV angle in both the relaxed posture and ideal posture, while student researcher 2 measured the CV angle only in the relaxed posture. Each subject's CV angle measurement was performed three times on three separate days and the means were used for further analysis. The shape of the CV angle frequency distribution was assessed using kurtosis and skewness values. Rater reliability was assessed using intraclass correlation coefficients (ICC), and interpreted based on the guidelines provided by Portney and Watkins (2009). Results: The CV angles were normally distributed in both relaxed and ideal postures. The mean and standard deviation (SD) of relaxed posture was 50.7o ± 6.3o with kurtosis and skewness of 0.67 and −0.74 respectively. The mean and SD of ideal posture was 55.5o ± 5.4o, with kurtosis and skewness of 0.1 and −0.54 respectively. The ICC for inter-rater reliability in the relaxed posture was 0.88 and the ICC for intra-rater reliability for relaxed posture was 0.91. Conclusions: Craniovertebral angles were normally distributed in the sample. An acceptable level of inter- and intra-rater reliability can be attained when measuring CV angle using a cloud-based video communication platform.
Analysing online discussions: What are students learning?

Online asynchronous discussions (OADs) are increasingly advocated to encourage interaction in blended learning in higher education. However, questions remain over the educational utility of OADs. In particular, relatively little is known about how students use online discussions and the ways and extent to which their use enhances learning. Previous research seeking to investigate the correlation between discussion board use and exam results has proved problematic and open to misinterpretation. Analysis of the content of online discussions may provide a more fruitful way of discovering the impact on student learning, but this approach can appear overly complex and time-consuming. This paper describes a small scale research project which pilots a number of different methods for analysing online discussions and considers the advantages and disadvantages with each approach, both in terms of methodological simplicity and utility of findings.
The Diagnostic Challenges in Patient with Multiple System Atrophy: A Case Report

Introduction Multiple system atrophy (MSA) is a rare, severe adult onset, sporadic, progressive neurodegenerative movement disorders that are still poorly understood. It is characterized by cerebellar ataxia, autonomic disorders, and parkinsonism syndrome in various combinations. The incidence rate is 0.6 cases per 100,000 people per year. Prevalence is 45 cases per 100,000 people. Despite of the presence of well-established clinical criteria for multiple system atrophy, ante-mortem diagnosis is difficult. Case We present a case of 44-year-old, male who with unsteady, wide based gait and rigidity which had developed gradually for 2 years. One year after the appearance of the first symptoms, he developed dysarthria, difficulty in swallowing, dizziness when changing position, and bladder incontinence. From neurologic examination we found orthostatic hypotension, dysmetria and dysdiadochokinesia on the both side. He met all the major criteria for possible rapid progression of MSA. In addition, brain Magnetic Resonance Imaging (MRI) showed prominent solids left and right cerebellum hemispheres and slight atrophy pons. Conclusion Our case can be classified as MSA according to the diagnostic criteria because the definitive diagnosis of MSA is only based on post-mortem pathological analysis. From this case we can learn that diagnosing MRA is quite challenging especially in early years of disease. The importance of good MRI interpretation and early finding of brain MRI abnormality can improve the accuracy of MSA diagnosis.
Names and Naming Practices of the Telugu in Malaysia

Names and naming practices reflect the socio-cultural background of a community. The giving of names is therefore not merely an act of labelling but represents constructs of identity that reflect the collective self-representation of a community and its worldviews. This study examines the naming practices of the Telugu in Malaysia and investigates the morphological structure and the semantic properties of Telugu names. To accomplish those research goals, survey interviews were conducted with 288 respondents in four different Malaysian states. Using descriptive statistics, a narrative analysis of the survey responses was used. Six experts in the Telugu culture were then invited for a focus group discussion. Before the results of this analysis are presented, detailed information about the Telugu and their naming traditions are provided. As will be shown here, among the Telugu, name-giving is a sacred act that is performed during a traditional naming ceremony called the Barasala. During this ancient oral onomastic tradition, names are passed on from one generation to the next and ancestral blessings are bestowed. As this study reveals, the structure of the patronymic names given during this ceremony reflect the religious beliefs and cultural identity of the Telugu.
Stereophotogrammetry of clouds observed during T-REX

Stereophotogrammetric images collected during the Terrain-induced Rotor Experiment (T-REX), which took place in Owens Valley, California, in the spring of 2006, were used to track clouds and cloud fragments in space and time. We explore how photogrammetric data complements other instruments deployed during T-REX, and how it supports T-REX objectives to study the structure and dynamics of atmospheric lee waves and rotors. Algorithms for camera calibration, automatic feature matching, and 3D positioning of clouds were developed which enabled the study of cloud motion in highly turbulent mountain wave scenarios. The dynamic properties obtained with photogrammetric tools compare well with data collected by other T-REX instruments. In a mild mountain wave event, the whole life cycle of clouds moving through a lee wave crest was tracked in space and time showing upward and downward motion at the upstream and downstream side of the wave crest, respectively. During strong mountain wave events the steepening of the first lee wave as it developed into a hydraulic jump was tracked and quantified. Vertical cloud motion increased from ~2 m s -1 to 4 m s -1 and horizontal cloud motion decreased from 20 m s -1 to 16 m s -1 with the development of the hydraulic jump. Clouds at distinct vertical layers were tracked in other mountain wave events: moderate southerly flow was observed in the valley (~8 m s -1 ), westerly motion of the same magnitude at the Sierra Nevada mountain crest level, and westerlies with speeds of over 20 m s -1 at even higher altitudes.
THE BEHAVIOR OF

The existing experimental data on UO_ and PuO_ aerosols a re evaluated and an empirical model of the behavior of aerosols produced in the p r i m a ry containment by the LMFBR DBA is de veloped. This model is based on the well known " s t i r r ed settling" law for a e r o s o l s. It permits a conservative, but physically r e a l istic, estimate of the specific reduction factor for the aerosol concentration in the p r i m a ry containment for any given plant due to agglomeration and subsequent fallout. Such an estimate should provide an adequate and useful interim guide for both LMFBR de signers and DRL staff.
Quantitative changes in arterial blood sugar during canine anaphylactic shock.

Following the observation that glycogen disappears almost quantitatively from the canine liver during the first fifteen minutes of typical anaphylactic shock, 1 we have determined the parallel quantitative changes in blood sugar. The determinations were made by the Meyers-Bailey modification of the Lewis-Benedict technique. Blood from non-etherized normal dogs shows a sugar content varying from 0.10 percent to 0.12 percent. On etherization the blood sugar rises to 0.13 percent to 0.18 percent, an average of 0.15 percent in our series. The sugar remains fairly constant at this level, with maximum variations of 0.03 percent. Two control non-sensitized dogs (morphine-ether anesthesia), and two dogs giving only slight suggestions of horse serum sensitization (by Kymograph readings) were injected intravenously with 1 cc. to 2 cc. horse serum per Kg. of body weight. The blood sugar remained almost constant in these animals for thirty minutes, with maximum variations of 0.02 percent above or below the initial readings. Four dogs giving typical anaphylactic shock were injected with 1 cc. to 2 cc. of horse serum per kg. of body weight. In all four the blood sugar increased rapidly in amount, reaching a maximum of 0.25 percent to 0.27 percent in from ten to thirty minutes, an average increase of 0.10 percent above the initial readings. These percentages are practically identical with the thirty minute blood sugar readings in normal dogs, after intravenous injection of glucose equivalent to the total estimated glycogen content of the liver.
Insider Trading in Family Firms: Impact of Family Ties and Management Involvement

We study corporate insider trading and information leakages within family firms. We find that the prof-itability of insider purchases of family insiders is higher compared to those of nonfamily insiders. In contrast, the profitability of insider sales of family insiders is lower compared to those of nonfamily insiders, indicating that family members time their insider trades well when buying shares, but not when selling shares. Furthermore, family insiders without management involvement time their insider sales significantly better, compared to family insiders who are involved in the firm management. Regarding information leakage, abnormal short-selling volumes prior to insider sales are higher when shares are sold by family insiders without management involvement, compared to family insiders who are in-volved in management.
Towards Image Caption Generation for Art Historical Data

One of the first steps to understanding images is by reading their captions. In the field of computer vision and natural language processing, generating captions from images has been an important and a challenging problem. In this work, we aim at understanding the pioneering work in neural caption generation, Show-and-Tell [4], with respect to art historical data. Artworks are characterized by various artistic styles, attributes, and motives; along with great diversity of artists creating these artworks and the different periods in history when these were created. This makes it very challenging to build models that are agnostic to all such variations. In this work, we propose an art history based image captioning dataset of 4000 images across 9 iconographies (annunciation, adoration, baptism, still-life, nativity, virgin and child, rape, tower of babel and noli me tangere) along with a description for each image consisting of one or more paragraphs. Inspired by [4], we fine-tune the captioning models on our new data. We conduct a series of ablation studies with various embedding sizes and state-of-the-art (SOTA) architectures as backbone like ResNet, ResNext and EfficientNet along with the proposed InceptionNet [4]. We use these SOTA image classification models to evaluate their ability of generating features for captioning. For quantitative evaluation and comparison, we use the standard 4 BLEU metrics [2]. This value indicates how similar the candidate text is to the reference texts. Higher BLEU scores represent higher similarity between predicted and reference text. In addition to the quantitative comparison, a qualitative discussion on the predicted captions is also presented. Results & Observations 1. Table 1: Based on Flickr8k dataset, we observe that the performance decreases with increase in embedding sizes for both the architectures, via the BLEU scores for the last (30) epoch of training. Empirically, we observe that an embedding size of 512 gives the best result. The performances of Inception and ResNext101 are comparable, and as such either can be chosen for the task.
Which Students Benefit from Independent Practice? Experimental Evidence from a Math Software in Private Schools in India

Abstract This study is one of the first evaluations of independent (i.e., self-guided) practice in math in a developing country. We randomly assigned 4,461 students in grades 4–7 in “unaided” private schools across seven Indian cities who were using a computer-assisted learning software to: (a) a control group, in which they moved from one unit to the next upon completion; or (b) a treatment group, in which they had to complete practice exercises before progressing to the next topic. After six months, the additional practice had a precisely estimated null effect on the math achievement of the average student. However, treatment students with low initial performance outperformed their control counterparts by 0.14 standard deviations (SDs). Our results suggest that independent practice may help private-school students from relatively well-off families in need of catching up with their peers.
FestNet: A Flexible and Efficient Sliced Transport Network

Network slicing was adopted as a solution for future networks to support various applications with diverse requirements. While active research has focused on this functionality, most of the work targets RAN or packet core slicing and leaves the transport network nearly untouched. With packet core functions moving to data centers and parts of RAN functions moving to edge clouds, the transport network will gain significantly more importance. To ensure stringent service level agreements (SLAs) and facilitate slice management, it is imperative for the transport network to support live slice mobility with no disruption of current services. In this paper, we present FestNet, a Flexible and Efficient Sliced Transport Network, achieved by our virtualized Programmable Data Plane (vPDP) and two-layer design. Not only conventional protocols but also stateless and stateful network functions (NFs) can be integrated as slices in FestNet. We implemented a FestNet prototype. Our evaluation shows that FestNet supports live slice migration with no packet loss and no state loss for stateful slices and that FestNet provides many times faster slice operations than implementations in related work.
