Factors that Contribute to Resident Teaching Effectiveness

Background One of the key components of residency training is to become an educator. Resident physicians teach students, advanced practice providers, nurses, and even faculty on a daily basis. Objective The goal of this study was to identify the objective characteristics of residents, which correlate with perceived overall teaching effectiveness. Methods We conducted a one-year, retrospective study to identify factors that were associated with higher resident teaching evaluations. Senior emergency medicine (EM) teaching residents are evaluated by medical students following clinical teaching shifts. Eighteen factors pertaining to resident teaching effectiveness were chosen. Two items from the medical students' evaluations were analyzed against each factor: teaching effectiveness was measured on a five-point Likert scale and an overall teaching score (1-75). Results A total of 46 EM residents and 843 medical student evaluations were analyzed. The ACGME milestones for systems-based practice (p = 0.02) and accountability (p = 0.05) showed a statistically significant association with a rating of “five” on the Likert scale for teaching effectiveness. Three other ACGME milestones, systems-based practice (p = 0.01), task switching (p = 0.04), and team management (p = 0.03) also showed a statically significant association of receiving a score of 70 or greater on the overall teaching score. Conclusion Residents with higher performance associated with system management and accountability were perceived as highly effective teachers. USMLE and in-service exams were not predictive of higher teaching evaluations. Our data also suggest that effective teachers are working in both academic and community settings, providing a potential resource to academic departments and institutions.

Application of a Monte Carlo model to predict space heating energy use of Belgrade's housing stock

Detailed domestic stock energy models can be used to help formulate optimum energy reduction strategies. However, there will always be considerable uncertainty related to their predictions due to the complexity of the housing stock and the many assumptions required to implement the models. This paper presents a simple Monte Carlo (MC) model that can be easily extended and/or transformed in relation to data available for investigating and quantifying uncertainties in both the housing stock model's predictions and scenario assumptions. While 90% of the MC model predictions fell within a range which is ±19% the mean value, 50% of them were within ±8% of the mean. The findings suggest that the uncertainties associated with the model predictions and scenario assumptions need to be acknowledged fully and – where possible – quantified as even fairly small variability in the influential variables may result in rather large uncertainty in the aggregated model's prediction.
Multiple exposition to a driving simulator reduces simulator symptoms for elderly drivers

This study examines how older drivers responded to repeated exposures to a driver simulator. Older active and fit drivers participated in 5 simulator sessions within a 14-day period. For each session, simulator sickness symptoms were measured with the Simulator Sickness Questionnaire at baseline and post-session. In addition, participants completed a 10-cm visual analog scale (0= no symptom, 10= mild nausea) at baseline and after a familiarization scenario and post-session. Overall, older adults adapted to the driving simulator and by the fourth session, they showed no difference in sickness scores between the baseline and the post-session measurements. Increasing the exposure duration at session 5 yielded an increase in the sickness symptoms. These results suggest that shorter- duration multiple exposures could reduce simulator sickness symptoms in elderly drivers and allow a more effective use of simulators for training by preventing early withdrawal of participants.
A synopsis of Lychnophorinae (Asteraceae: Vernonieae)

A new classification of the subtribe Lychnophorinae is proposed based on the results of phylogenetic analyses. The subtribes Centratherinae and Sipolisiinae are synonyms of Lychnophorinae and three genera (Albertinia, Blanchetia, Gorceixia) are transferred to the subtribe. As now circumscribed, Lychnophorinae comprises 19 genera and 117 species distributed mostly in the Cerrado domain of the Brazilian Central Plateau. Oiospermum is synonymized under Centratherum, and Irwinia under Blanchetia. Because Lychnophora as currently circumscribed is paraphyletic, the genus is dismantled into three monophyletic genera: Lychnophora s.s. , Lychnocephalus and a new genus described herein, Lychnophorella. Seven new species are described (Chronopappus lanatus, Lychnophora grisea, L. haplopappa, Lychnophorella jacobinensis, Piptolepis riparia, Prestelia espeletoidea and Proteopsis hermogenesii), 16 new combinations are proposed (Eremanthus reticulatus, E. syncephalus, Lychnocephalus humillimus, L. mellobarretoi, L. sellowii, Lychnophora hatschbachii, Lychnophorella blanchetii, L. bishopii, L. leucodendron, L. morii, L. regis, L. santosii, L. sericea, L. triflora, Piptolepis pabstii, Prestelia purpurascens) as well as eight new synonyms. We also propose a neotype for Ampherephis pulchella, an epitype for Crantzia ovata and lectotypes for 31 names including six second-step lectotypifications (Albertinia brasiliensis, A. polycephala, Ampherephis intermedia, Centratherum fruticosum, Eremanthus leucodendron, E. purpurascens, Gorceixia decurrens, Lychnophora albertinioides, L. brunioides, L. microphylla, L. pohlii, L. reticulata, L. rosmarinus var. affinis, L. rosmarinus var. normalis, L. sellowii, Piptolepis gardneri, Proteopsis sellowii, Symblomeria baldwiniana, Vanillosmopsis albertinioides, V. glomerata, V. pohlii, V. syncephala, Vernonia burchelliana, V. ericoides, V. imbricata, V. involucrata, V. leptospermoides, V. martiana, V. platycephala, V. pseudomyrtus and V. trichocarpha).
The Preventive Effects and the Mechanisms of Action of Navel Orange Peel Hydroethanolic Extract, Naringin, and Naringenin in N-Acetyl-p-aminophenol-Induced Liver Injury in Wistar Rats

N-Acetyl-p-aminophenol (APAP) or acetaminophen is the most common drug ingredient worldwide. It is found in more than 600 different over-the-counter and prescription medicines. Its long-term and overdose use is highly toxic and may result in liver injury. Thus, this study was designed to assess the preventive effects and to suggest the mechanisms of action of the navel orange peel hydroethanolic extract, naringin, and naringenin in APAP-induced hepatotoxicity in male Wistar rats. APAP was administered to male Wistar rats at a dose level of 0.5 g/kg body weight (b.w.) by oral gavage every other day for 4 weeks. APAP-administered rats were treated with the navel orange peel hydroethanolic extract (50 mg/kg b.w.), naringin (20 mg/kg b.w.), and naringenin (20 mg/kg b.w.) by oral gavage every other day during the same period of APAP administration. The treatments of APAP-administered rats with the peel extract, naringin, and naringenin produced a significant decrease in the elevated serum AST, ALT, ALP, LDH, and GGT activities as well as total bilirubin and TNF-α levels while they induced a significant increase in the lowered serum albumin and IL-4 levels. The treatments also resulted in a significant decrease in the elevated liver lipid peroxidation and enhanced the liver GSH content and SOD, GST, and GPx activities as compared with APAP-administered control; the peel extract was the most potent in improving the liver LPO, GSH content, and GPx activity. In addition, the three treatments significantly downregulated the elevated hepatic proapoptotic mediators p53, Bax, and caspase-3 and significantly upregulated the suppressed antiapoptotic protein, Bcl-2, in APAP-administered rats. In association, the treatments markedly amended the APAP-induced liver histopathological deteriorations that include hepatocyte steatosis, cytoplasmic vacuolization, hydropic degeneration, and necrosis together with mononuclear leucocytic and fibroblastic inflammatory cells' infiltration. In conclusion, the navel orange peel hydroethanolic extract, naringin, and naringenin may exert their hepatopreventive effects in APAP-administered rats via enhancement of the antioxidant defense system and suppression of inflammation and apoptosis.
Aerodynamic Devices for Tall Buildings and Structures

Wind tunnel tests were conducted to investigate the effects of some aerodynamic devices on the wind‐induced responses of tall buildings and structures. It was found that the fitting of small fins or vented fins to a square tower caused an increase in the along‐wind response, while reduction in cross‐wind response occurred only for a limited range of reduced wind velocities. The use of slotted corners resulted in significant reductions in both the along‐wind and cross‐wind responses over an extended range of reduced wind velocities. The concept of slotted corners is practical and could be useful in the design of modern tall buildings and structurees.
DeepFlowGen: Intention-Aware Fine Grained Crowd Flow Generation via Deep Neural Networks

Obtaining crowd flow distribution with recognized human intention is extremely valuable for a series of applications for metropolitan cities. Previous solutions look at spatial correlation and temporal periodicity based on historical crowd flow information to calculate future crowd flow distribution. However, these mechanisms cannot recognize the intention behind crowd flow. We address this problem by leveraging a key insight – people's intention behind their movement is highly correlated with the point-of-interest (POI) distribution of the corresponding regions and adjacent regions. Therefore, we propose DeepFlowGen to model the complicated relationship between crowd flow, POI, check-ins, and time to generate intention-aware crowd flow. Specifically, we solve the conflict between dynamic crowd flow and static POI distribution by fusing the information in both time and POI domains. Besides, we employ a sequence of residual blocks in DeepFlowGen to address the challenges of modeling the diverse temporal rhythms and heterogeneous influence of POI. Furthermore, we examine the generated intention-aware crowd flow from two aspects to substantiate the reasonability of DeepFlowGen. Extensive experiments demonstrate that our model outperforms the state-of-the-art solutions by at most 30 percent in terms of NRMSE of total crowd flow. Moreover, the correlation between the generated intention-aware crowd flow and the check-in distribution across different categories of POIs is as high as 0.90 and 0.80 in Beijing and Shanghai. Combined with extensive case studies, we demonstrate the strong ability of our model in generating intention-aware crowd flow.
Finite Element Formulations Applied to Outer Ear Modeling

The work described in this paper is part of a broader research activity on the development of a virtual ear. The present study focuses on the tympanic membrane and auditory canal modeling, which are important components in sound transmission. The standard finite element method (FEM) and an alternative method (the generalized FEM), suitable for modeling sound propagation at high frequencies, were applied. Two domains (fluid and structural) for the auditory canal and the tympanic membrane, respectively, were considered in order to evaluate the coupling of the different methods and to apply a fluid-structure interaction formulation. ANSYS ® software was used for solving FEM analyses, while GFEM simulations were obtained by implementing the method in Wolfram Mathematica®. Simulation results include modal response, pressure distribution in the auditory canal and displacement distribution in the tympanic membrane. The identified modal frequencies of the auditory canal agree with published data reported in the literature. The validation of such method with standard FEM simulation at increasing mesh density shows that FEM is more suitable for simulations of the human ear in the audible frequency range, although the generalized formulation could be convenient if an ear model including the whole head or the ultrasound frequency range were investigated.
Ethanolic Leaves Extract of Awar-awar (Ficus Septica) as Selective Chemopreventive Agent on Various Cancer Cells

Treatment of cancer such as surgery, radiotherapy and chemotherapy have many side effects such as cardiotoxicity, hepatotoxicity, and immunosuppressant, therefore selective cochemopreventive agent is needed. Awar-awar (Ficus septica) is a traditional medicinal plant that is known as a potential cancer chemopreventive agent. The purpose of this study was to determine the cytotoxic effect of ethanolic leaves extract of awar-awar (EFs) against 4T1 and MCF7/HER2 breast cancer cells; WIDR colon cells cancer, HeLa cervix cells cancer, and Vero normal cells. The cytotoxic test was performed by MTT assay. The parameter obtained from the cytotoxic test was IC50. Selectivity index was determined from IC50 ratio of cancer cells to normal cells Vero. The results showed that EFs has a cytotoxic activity on cancer cell line with IC50 61,2 µg/mL on 4T1; 48 µg/mL on MCF7/HER2; 122,4 µg/mL on Hela; 75,9 µg/mL on WiDR; and 394,8 µg/mL on Vero. It can be concluded that EFs has high selectivity on various cancer cells with selectivity index more than 3.
NFκB and Kidney Injury

The global burden of chronic kidney disease will increase during the next century. As NFκB, first described more than 30 years ago, plays a major role in immune and non-immune-mediated diseases and in inflammatory and metabolic disorders, this review article summarizes current knowledge on the role of NFκB in in vivo kidney injury and describes the new and so far not completely understood crosstalk between canonical and non-canonical NFκB pathways in T-lymphocyte activation in renal disease.
The effects of GIC on protective relaying

This paper summarizes research and operating experience related to the effects of geomagnetically induced currents (GIC) on protective relaying. It shows that if the GIC causes high levels of harmonic distortion, there is a risk that the conventional protection system may not provide adequate protection for the capacitors, transformers, and generators. It recommends methods to reduce the risk of false tripping and the risk of failure to protect the power apparatus.
Management of Diabetes Mellitus in Islamic Fasting

Introduction: Millions of Muslims across the globe fast during the holy month of Ramadan, as well as on the other specific dates of the lunar calendar. Although the Islamic law exempts patients from fasting, more than 50 million Muslim patients with diabetes mellitus fast during Ramadan. Ramadan fasting in diabetic patients may increase the risk of various complications, such as hypoglycemia, hyperglycemia, diabetic ketoacidosis, hypovolemia, and thrombosis. This study aimed to review the safe management of blood glucose in the diabetic patients willing to fast during Ramadan. Â Methods: This literature review was conducted via searching in databases such as Medline, PubMed, PMC, Google Scholar, ScienceDirect, Cochrane Library, and the reference lists of relevant articles. Â Results: The diabetic patients who are willing to fast during Ramadan should be prepared within at least 1-2 months prior to the beginning of Ramadan through Ramadan-focused advice, medical assessment before Ramadan, modifications in their medication protocol, balanced diet, physical activity plans, and advice on the self-monitoring of blood glucose. Â Conclusion: According to the results, safe Ramadan fasting in diabetic patients could be achieved with the help of healthcare providers, including physicians and pharmacists.
Experimental investigations and numerical modeling of a mixed flow marine waterjet

Recently, waterjet propulsion has gained great commercial interest as the shipping industry trends toward faster passenger ferries and other fast transport vessels. The work presented in this thesis was part of a larger effort to improve the capabilities and performance of a mixed flow marine waterjet used in such high speed marine applications. An experimental test faciity was constructed and employed in the testing of a mixed flow marine waterjet rotor, stator and housing set. Full description of the facility and waterjet test procedures are discussed. The pumpset was designed using a coupled Lifting Surface/RANS procedure by Taylor et.al.[35] and was built and tested as part of the work presented in this research. Detailed measurements of the pump performance is described including pump curves, tipgap studies, inlet, midstage and outlet velocity and pressure profiles in an axisymmetric inflow. Full accounting for losses including rotor and stator loss profiles as well as a full pumpset energy balance is presented. From the results of the experiment, dominant losses were found near the tip/duct junction casing along with a large and unexpected increase in swirl in this region. Detailed numerical modelling of this pumpset was performed using both a Lifting Surface/RANS procedure and a Lifting Surface/Euler solver. Effects of losses were modelled as well as tipgap effects. Prior work had developed these coupling procedures but the computationally efficient Euler coupling lacked the introduction of loss and drag induced swirl. This loss coupling was added to the model and the analysys results are discussed. Also, a model to align the wakesheet with the local flowfield in the Lifting Surface solver was developed and these results are discussed. Thesis Supervisor: Justin E.

The branched chain amino acids in autism spectrum disorders

Autism spectrum disorders (ASD) are a group of genetic disorders often overlapping with other neurological conditions. Despite the remarkable number of scientific breakthroughs of the last 100 years, the treatment of neurodevelopmental disorders (e.g. autism spectrum disorder, intellectual disability, epilepsy) remains a great challenge. Recent advancements in geno mics, like whole-exome or whole-genome sequencing, have enabled scientists to identify numerous mutations underlying neurodevelopmental disorders. Given the few hundred risk genes that were discovered, the etiological variability and the heterogeneous phenotypic outcomes, the need for genotype -along with phenotype- based diagnosis of individual patients becomes a requisite. Driven by this rationale, in a previous study our group described mutations, identified via whole - exome sequencing, in the gene BCKDK – encoding for a key regulator of branched chain amin o acid (BCAA) catabolism - as a cause of ASD. Following up on the role of BCAAs, in the study described here we show that the solute carrier transporter 7a5 (SLC7A5), a large neutral amino acid transporter localized mainly at the blood brain barrier (BBB), has an essential role in maintaining normal levels of brain BCAAs. In mice, deletion of Slc7a5 from the endothelial cells of the BBB leads to atypical brain amino acid profile, abnormal mRNA translation and severe neurolo gical abnormalities. Additionally, deletion of Slc7a5 from the neural progenitor cell population leads to microcephaly. Interestingly, we demonstrate that BCAA intracerebroventricular administration ameliorates abnormal behaviors in adult mutant mice. Furthermore, whole - exome sequencing of patients diagnosed with neurological dis o r ders helped us identify several patients with autistic traits, microcephaly and motor delay carrying deleterious homozygous mutations in the SLC7A5 gene. In conclusion, our data elucidate a neurological syndrome defined by SLC7A5 mutations and support an essential role for t he BCAA s in human bra in function. Together with r ecent studies (described in chapter two) that have successfully made the transition into clinical practice, our findings on the role of B CAAs might have a crucial impact on the development of novel individualized therapeutic strategies for ASD.
Assessing heat pumps as flexible load

In a future power system featuring significant renewable generation, the ability to manipulate domestic demand through the flexible operation of heat-led technologies such as heat pumps and micro-combined heat and power could be a critical factor in providing a secure and stable supply of electrical energy. Using a simulation-based approach, this study examined the linkage between the thermal characteristics of buildings and the scope for flexibility in the operating times of air source heat pumps. This was assessed against the resulting impact on the end-user’s comfort and convenience. A detached dwelling and flat were modelled in detail along with their heating system in order to determine the temporal shift achievable in the heat pump operating times for present-day and future dwellings. The simulation results indicated that the scope for shifting heat pump operating times in the existing building stock was limited, with time shifts of only 1–2 h achieved before there was a serious impact on the comfort of the occupant. However, if insulation levels were dramatically improved and substantial levels of thermal buffering were added into the heating system, sizable time shifts of up to 6 h were achievable without a significant impact on either space or hot water temperatures.
