PRELIMINARY STUDY OF FLOORING IN SCHOOL IN THE U.S.: AIRBORNE PARTICULATE EXPOSURES IN CARPETED VS. UNCARPETED CLASSROOMS

Data sets from 16 schools (grades K-6 and a Junior High), spanning 5 southwestern states in the USA, have been analyzed to examine classroom airborne particulate levels and the buildup of contaminants on flooring systems. The data have been collected from 2 separate sites (one carpeted, one hard flooring) within each of the schools. Measurements included indoor/outdoor airborne particulate mass concentration (PM2.5), indoor/outdoor particulate counts (> 0.5 microns), and CO2/T/RH to characterize ventilation in the classrooms. The study must be considered more of a preliminary survey due to the limited number of schools examined. A comparative analysis of the data sets suggests that school carpeted floor covering may present an increased exposure risk to children from particulate matter harbored on the flooring material as compared to hard-surfaced flooring. The study emphasizes the need for fastidious maintenance of all types of floor coverings in schools.
Design of Adaptive Digital Transversal Equalizers

This contribution deals with the dimensioning of complex digital transversal equalizers for adaptive operating modes. All the quantizing effects occurring in the equalizer are analyzed so that the word lengths necessary in a particular case can be exactly determined. Finally, dimensioning is carried out, as an example, for an equalizer for a 256-QAM modem and tested by means of a simulation calculation. Übersicht: Dieser Beitrag behandelt die Dimensionierung komplexer digitaler Transversalentzerrer für adaptive Betriebsweise. Alle im Entzerrer vorkommenden Quantisierungseffekte werden analysiert, so daß die notwendigen Wortlängen für jeden Einzelfall genau bestimmt werden können. Schließlich wird die Dimensionierung exemplarisch anhand eines Entzerrers für ein 256-QAM-Modem durchgeführt und mit Hilfe von Simulationsrechnungen überprüft.

A Weak Temperature Gradient Framework to Quantify the Causes of Potential Intensity Variability in the Tropics

Potential intensity (PI) has been shown to have a linear sensitivity to sea surface temperature (SST) of about 8m s K, which is close to the sensitivity of PI in simulations subject to aweak temperature gradient (WTG) approximation. This suggests that most of the PI variance is associated with local rather than global SST variations. We verify that PI perturbations are approximately linear in SST, with slopes of 1.86 0.2m sK in radiative–convective equilibrium (RCE) and 9.1 6 0.9m sK in WTG. To do so, we simulate the sensitivity of both RCE and WTG states in a single-column model (SCM) perturbed by changing in turn CO2 concentration, aerosol concentrations, prescribed SST, and surface winds speeds. While PI is much more sensitive to SST in WTG than in RCE simulations, the SST itself is much less sensitive to radiative forcing inWTG than in RCE because of the absence of strong atmospheric response. Using these results, we develop a linear model, based on SST and midlevel saturation MSE perturbations, to partition SST and PI perturbations between local components occurring under a WTG constraint and global components that are representative of an RCE state. This model explains up to 95% of the variability of PI in reanalysis. The SCM-derived linear model coefficients are statistically indistinguishable from coefficients from a linear fit of reanalysis PI to SST and midlevel saturation MSE in most ocean basins. Our model shows that North Atlantic PI variations are explained almost entirely by local forcings in recent decades.
Is Seeing Intriguing? Practitioner Perceptions of Research Documents

Although design practitioners have a myriad of information sources available, they often have little time to evaluate the information. The need to study visual persuasive tactics is highlighted by (1) the propensity of designers to use visual communications, (2) the availability of sources that range in validity, (3) work stressors encountered by designers, and (4) the benefits of using peer–reviewed sources. Given these contexts, it may behoove design scholars to acknowledge the constraints and desires of their intended audience, which may include practicing interior designers. Framed by Petty and Cacioppo's Elaboration Likelihood Model (ELM) of persuasion, this study's goal was to compare design practitioners’ hedonic perceptions of empirical research documents. Thirty–four participants completed a mixed–method survey soliciting perceptions relative to the organizational strategies and word–to–image ratios of two document iterations. Responses ascertained from Likert–type scales, heat maps, and open–ended questions suggest that designers, at times, evaluate an information source based on the graphic quality in which it is presented. Taken together, findings from this study might provide some useful guidance for those conveying information to practitioners who are less familiar with academic literature but could benefit from the knowledge provided, thus increasing the likelihood of informed design decision–making practices. Furthermore, the methods utilized during this inquiry might serve as a pilot for future studies in this area.
Management of invasive, plague-carrying signal crayfish by physical exclusion barriers

Invasive, plague-carrying signal crayfish represent a significant threat to imperiled European crayfishes. In the absence of a feasible eradication technique, physical barriers that separate invasive from native crayfish populations have been suggested as management strategy. Here, we investigated the effectiveness of three serial barriers with different functionality (flow-based vs . waterfall-based) in a headwater stream in southwestern Germany on containment of signal crayfish and crayfish plague. Crayfish distribution was surveyed three and six years after the construction of the barriers using manual search, trapping, and eDNA detection, whereby a tributary stream without barriers served as a form of control for a “do-nothing” scenario. The efficacy of the barriers was also empirically assessed by stocking marked crayfish downstream of the barriers and tracking their nocturnal behavior. After six years, native crayfish were still present upstream of the barriers but went extinct in the control stream due to signal crayfish invasion. Following two years of extreme drought after the first survey, signal crayfish were able to overcome the flow-based barrier but were never detected upstream of the waterfall-based barriers. Overall, this case study provides evidence for the effectiveness of intentional stream fragmentation as management strategy against invasive aquatic species.
DA LI POSTOJI VEZA ANKSIOZNOSTI KAO CRTE LIČNOSTI SA CRTAMA DEPRESIVNE LIČNOSTI?

Uvod/Cilj: Rezultati dosadašnjih istraživanja ukazuju da postoji povezanost između simptoma depresije i anksioznosti, kao i da je javljanje ovih simptoma delimično uslovljeno crtama ličnosti. Cilj ovog istraživanja je bio da se ispita da li postoji veza između anksioznosti kao crte ličnosti sa crtama depresivne ličnosti među odraslim ispitanicima iz Crne Gore, kako bi dobili smernice za primenu programa za očuvanje mentalnog zdravlja. Metode: U okviru ove studije preseka bilo je uključeno 355 ispitanika. Podaci od svih ispitanika iz Crne Gore prikupljeni su onlajn putem, kroz Google Forms platformu. Pored opšteg upitnika, korišćeni su upitnici za ispitivanje crta ličnosti anksioznosti (engl. Anxiety Trait 29 – AT29) i depresivnosti („Depresivna ličnost“ – DL). U statističkoj analizi podataka korišćen je Pearson-ov koeficijent korelacije i jednofaktorska analiza varijanse. Rezultati: Od 355 ispitanika, uzrasta od 18 do 68 godina, 74,6% su činile žene. Značajna visoka pozitivna korelacija dobijena je između crta anksioznosti i crta depresivne ličnosti (r=0,82, p<0,01). Pored toga, obe ove crte ličnosti bile su značajno više ispoljene kod žena, osoba sa nižim stečenim stepenom obrazovanja i lošim socio-ekonomskim stanjem. Mlađa i nezaposlena lica su imali značajno više izražene crte anksioznosti, ali značajna razlika nije utvrđena u pogledu izraženosti crta depresivne ličnosti. Nije bilo značajne ispoljenosti anksioznih i depresivnih crta ličnosti u odnosu na bračni status i zaposlenost. Zaključak: Kada znamo da se u značajnom broju slučajeva crte anksioznosti i depresivnosti javljaju zajedno, onda možemo osmisliti programe prevencije i podrške kod osoba kod kojih bi se rano detektovale ove crte, kako bi se sprečilo da poteškoće u funkcionisanju prerastu u anksioznost ili depresiju.
Pathophysiology of blood brain barrier dysfunction during chronic cerebral hypoperfusion in vascular cognitive impairment

The prevalence of cerebrovascular disease increases with age, placing the elderly at a greater lifetime risk for dementia. Vascular cognitive impairment (VCI) encompasses a spectrum of cognitive deficits from mild cognitive impairment to dementia. VCI and its most severe form, vascular dementia (VaD), is becoming a major public health concern worldwide. As growing efforts are being taken to understand VCI and VaD in animal models and humans, the pathogenesis of the disease is being actively explored. It is postulated that chronic cerebral hypoperfusion (CCH) is a major cause of VCI. CCH activates a molecular and cellular injury cascade that leads to breakdown of the blood brain barrier (BBB) and neurodegeneration. The BBB tightly regulates the movement of substances between the blood and the brain, thereby regulating the microenvironment within the brain parenchyma. Here we illustrate how BBB damage is causal in the pathogenesis of VCI through the increased activation of pathways related to excitotoxicity, oxidative stress, inflammation and matrix metalloproteinases that lead to downstream perivascular damage, leukocyte infiltration and white matter changes in the brain. Thus, CCH-induced BBB damage may initiate and contribute to a vicious cycle, resulting in progressive neuropathological changes of VCI in the brain. This review outlines the molecular and cellular mechanisms that govern BBB breakdown during CCH and highlights the clinical evidence in identifying at-risk VCI patients.

Background: Emergency contraception refers to methods of contraception that can be used to prevent pregnancy after sexual intercourse. About thirty percent of all pregnancies, and 61% of all unintended pregnancies, ended in an induced abortion in Nigeria, and many women with unwanted pregnancies decide to end them by abortion. Healthcare providers' knowledge and attitude towards emergency contraception is very important for dissemination of awareness, consumer acceptance and use of contraceptives, as health care workers interact with large numbers of women and are reliable sources of information. This study aimed to assess healthcare workers' emergency contraception knowledge, attitude and prescription practice. Materials and Methods: The study was a cross-sectional study. Healthcare workers providing services in Primary Health care facilities of Sokoto metropolis were studied. Using formula for sample size estimation for crosssectional study, a total of 419 respondents were recruited into the study using systematic sampling technique. The instrument of data collection was a structured interviewer administered questionnaire and data was collected by means of Open Data Kit for android App and analysed using IBM SPSS statistical software package version 23. Univariate and bivariate analysis were conducted; level of significance was set at 5%. Results: Few (39.9%) respondents knew that Intra uterine contraceptive devices can be used for emergency contraception, only 15.4% knew how emergency contraceptives work. Most (75.4%) believed that emergency contraceptives should be available only on prescription; and 30.5% felt that emergency contraceptive pills promote irresponsible behaviour. More than half of the respondents (56.5%) had prescribed within the last one month, 48.7% of them prescribed less than 5 times within the month. Only 27(8.0%) have ever prescribed emergency contraceptive pills in advance of need. Conclusion: The study respondents had good knowledge of emergency contraceptives, albeit, with some misconceptions, they also demonstrated good attitude, however, the prescription practice was fair.
HIGH RUNOFFS POLLUTION LOAD: IMPLICATIONS AND CONTROLLING MEASURES

Stormwater management has become an important part of the field of water resources management. The traditional method of disposing of urban stormwater was to drain it away as quickly as possible. However, in recent years, questions concerning the impacts on the receiving waters began to arise, and in response to these concerns, some communities have elected to encourage capturing and treating stormwater runoff. Heavy metals in highway runoff continue to be a national concern for most transportation agencies including Jammu & Kashmir Department of Transportation and NHAI . The metal contaminants carried in the stormwater runoff and eventual snowmelt enters nearby surface waters and contributes to their degradation as well as threaten the survival of aquatic organisms at all levels of the food chain. This pathway of heavy metal contamination has become a significant concern due to increased urbanization and roadway construction. The adverse impacts of the stormwater runoff can be minimized with structural and non-structural Best Management Practices (BMPs) or with a combination
BURSTINESS AND HIERARCHY IN TONAL CLASSICAL MUSIC

A musical work is, in general, a coherent whole that is more than the sum of its individual notes. We are interested in the emergent coherent behavior that arises from the combination of the sounds made by the individual pitches, focusing on the temporal aspect. We consider each pitch activation as an event, and examine the distribution of the interevent times, the time between the deactivation and consecutive activation of the same pitch. The interevent times in a sample of 428 works by four canonical Western composers obey heavy-tailed distributions, and these distributions can be attributed not to the pitch durations themselves but to the order in which pitches are activated. Our results imply that the generative process in music is neither random nor regular, and suggest the presence of hierarchy in pitch activations. We present our initial attempt in creating a hierarchical generative model of music, inspired by the similarities between our findings and Schenkerian analysis.
RECON syndrome is a genome instability disorder caused by mutations in the DNA helicase RECQL1

Despite being the first homolog of the bacterial RecQ helicase to be identified in humans, the function of RECQL1 remains poorly characterized. Furthermore, unlike other members of the human RECQ family of helicases, mutations in RECQL1 have not been associated with a genetic disease. Here, we identify 2 families with a genome instability disorder that we have named RECON (RECql ONe) syndrome, caused by biallelic mutations in the RECQL gene. The affected individuals had short stature, progeroid facial features, a hypoplastic nose, xeroderma, and skin photosensitivity and were homozygous for the same missense mutation in RECQL1 (p.Ala459Ser), located within its zinc binding domain. Biochemical analysis of the mutant RECQL1 protein revealed that the p.A459S missense mutation compromised its ATPase, helicase, and fork restoration activity, while its capacity to promote single-strand DNA annealing was largely unaffected. At the cellular level, this mutation in RECQL1 gave rise to a defect in the ability to repair DNA damage induced by exposure to topoisomerase poisons and a failure of DNA replication to progress efficiently in the presence of abortive topoisomerase lesions. Taken together, RECQL1 is the fourth member of the RecQ family of helicases to be associated with a human genome instability disorder.
Adaptive market hypothesis: An empirical analysis of the Wine Market

We test the nature of weak form informational efficiency present in the wine market using daily return of LIV-EX 50 index from 1/1/2010 to 12/6/2020. First, we employ a number of statistical tests including variance ratio tests, tests for linear and non-linear dependence and Hurst coefficient. The tests are applied on the full dataset and on four non overlapping sub-samples of equal length. The variance ratio tests provide a mixed regarding informational efficiency. Evidence of non-linear dependence in the return series was found. The Hurst coefficient values confirm the presence of long run persistence in the wine market. Based on the mixed evidence, we test the possibility of adaptive nature of the wine market. We employ the newly proposed Adaptive Index (AI) to quantify the degree of information inefficiency in the wine market at any instance. Our results confirm that wine market is adaptive and periodically shifts between states of efficiency and inefficiency. The wine market is found to be relatively free from the Covid-19 induced shock and the safe haven property of wine is thus confirmed. Finally, impact of various macroeconomic and financial events on wine market efficiency is identified by using AI.
Assessment of heavy metal contamination in soil around Piyungan Landfill, Yogyakarta, Indonesia

One of the negative impacts of the landfill as solid waste disposal is soil contamination by heavy metals. This study assessed heavy metals impact, especially Pb, Cu, Zn, and Cd, in the soil in Piyungan landfill, Bantul, Yogyakarta, Indonesia. The assessment was conducted by analyzing 15 soil samples from 25 cm depth in the study area, which was divided into three-zone. The study results showed that generally, the highest content of metals was found in zone II, which is located near or directly situated in a landfill site. The pollution index (PI) calculated showed in order Cd>Cu>Pb>Zn. The result also indicates that Cd has the highest pollution index and even the highest risk compared to Pb, Cu, and Zn. The eco-risk index (RI) calculation showed that the value was 29 to 70 demonstrating a low class. The result also indicates that the accumulation of heavy metals investigated in this study was normal, and that the ecological risk was relatively low.
Partial Replacement of Dietary Fat with Krill Oil or Coconut Oil Alleviates Dyslipidemia by Partly Modulating Lipid Metabolism in Lipopolysaccharide-Injected Rats on a High-Fat Diet

This study investigated the effects of partial replacement of dietary fat with krill oil (KO) or coconut oil (CO) on dyslipidemia and lipid metabolism in rats fed with a high-fat diet (HFD). Sprague Dawley rats were divided into three groups as follows: HFD, HFD + KO, and HFD + CO. The rats were fed each diet for 10 weeks and then intraperitoneally injected with phosphate-buffered saline (PBS) or lipopolysaccharide (LPS) (1 mg/kg). The KO- and CO-fed rats exhibited lower levels of serum lipids and aspartate aminotransferases than those of the HFD-fed rats. Rats fed with HFD + KO displayed significantly lower hepatic histological scores and hepatic triglyceride (TG) content than rats fed with HFD. The KO supplementation also downregulated the adipogenic gene expression in the liver. When treated with LPS, the HFD + KO and HFD + CO groups reduced the adipocyte size in the epididymal white adipose tissues (EAT) relative to the HFD group. These results suggest that KO and CO could improve lipid metabolism dysfunction.
Drug Triggers and Clinic of Acute Generalized Exanthematous Pustulosis (AGEP): A Literature Case Series of 297 Patients

Acute generalized exanthematous pustulosis (AGEP) is a rare skin reaction, commonly caused by drugs. Available evidence mostly relies on small studies or case reports. We collected published AGEP case reports and, subsequently, described the patient characteristics, suspect and concomitant drugs, time to onset, disease management, and clinical prognosis. This study included 297 AGEP patients (64.3% women) obtained from 250 published case reports or case series with individual patient data. AGEP affected patients of all ages, but the majority of patients (88.2%) were ≥25 years old. The most frequently reported suspect drugs were anti-infectives for systemic use (36.5%), particularly antibacterials for systemic use (31.0%), and especially beta-lactam antibacterials (18.3%) and macrolides (4.3%). Other frequent suspect drugs were antineoplastics (12.2%), and anti-inflammatory/anti-rheumatic products (5.2%) plus hydroxychloroquine (12.8%). Mean time to onset was 9.1 days (standard deviation SD 13.94). Some patients developed fever (64.3%) and systemic involvement (18.9%), and most patients (76.4%) received pharmacological treatment for AGEP. Seven patients died, although five of them were already critically ill prior to AGEP. In conclusion, antibiotics remain the most common suspected cause of AGEP. While case mortality rate may be up to 2.5%, disentangling the role of AGEP on the fatal outcome from the role of the preexisting health conditions remains challenging.
The effects of working agile on team performance and engagement

Purpose This study aims to examine the relationship between the agile way of working and team performance and engagement. Furthermore, psychological safety climate was investigated as a mediator of this relationship. As organizations are increasingly adopting the agile way of working method beyond the information technology (IT) setting, the authors researched its effects in teams across a variety of functional domains. Design/methodology/approach Survey data was collected from 97 agile teams working in various functional domains in a multinational bank. The data was analyzed using structural equation modeling. Findings Results indicated that the agile way of working is directly and positively related to team engagement and performance. Moreover, psychological safety climate acted as a partial mediator of each of the respective outcomes. Originality/value This study illustrated that the agile way of working is beneficial for teams beyond the IT setting, as it is positively associated with psychological safety climate, engagement and performance across functional domains.
