An experimental study on the influence of tubercles on aerodynamics performance of car rear spoiler

In this study, the aerodynamic performance of a car spoiler with tubercles configurations that was inspired by Humpback whale flipper morphology was investigated. This was done by producing three (T0, T3, and T9) spoiler designs where, tubercles sinusoidal protrusions pattern was applied at the leading edge of the spoiler. T0, is a base line spoiler that has no tubercles, T3, that contains three tubercles protrusions, and T9, contains nine tubercle protrusions. The baseline spoiler design was based on the Selig s2091 spoiler and the spoiler has a chord length (C) 100mm and 290mm wingspan. The spoiler was tested angle of attack from - 20 to 30° and at Reynolds number 60000 in an open circuit subsonic wind tunnel. The aerodynamic performance of the spoiler was measured by the recorded time averaged lift and drag. From the recorded it was observed that at certain angles of attack, the presence of a tubercle pattern can bring a significant aerodynamic improvement.
LTCC slot array antenna for 5G application

We develop the antenna module substrate which is broadband and large gain using an LTCC technology in a 28GHz band in this study. We used LTCC materials (dielectric constant 5.8, Dielectric loss 0.002@28GHz) which we developed for materials originally. First of all, we confirmed ability of slot array antenna made by LTCC for 5G application to get broadband property. The structure of designed array antenna became 40mm × 3.2mm × t1.6mm. We confirmed that this antenna has wider bandwidth (2.2GHz) and higher gain (6dBi). But this antenna size is too large for applying mobile device. Therefore we redesigned to reduce antenna size without specification degradation. The structure of redesigned antenna element becomes basically 4.8mm × 6.7mm × t1.0mm. This antenna has wider bandwidth (2.7GHz). The gains are more than 5dBi for the characteristic of this element in a band. Assume this antenna a fabric; 2 × 2 (4 elements: for mobile device) and 4 × 4 (16 elements: for small cell base station) we make an array antenna for Small cell base station and for mobile device. We will evaluate a beam steering examination with emission properties (gain, beam angle).
How African American Men from Challenging Backgrounds Beat the Odds and Graduated from College

While Bettis and Sternod (2009) asserted the notion of boys being in crisis as not a new phenomenon but a historically cyclical one, present research contends that African American men are one of the most at-risk groups in the United States. School and criminal-justice systems show similar results. African American men continue to lag in terms of graduation rates and college enrollment, while being overrepresented in victim violence and the criminal justice system. They also lead the nation in homicides as both victims and perpetrators. Despite these obstacles, many at-risk African American men graduate from college and excel in life. A variety of protective factors contributes to their progress. While the reasons for failed progress and risk factors are saturated within the research, there remains few outlets that focus on protective factors that have helped many African American men. As such, this study explored and identified protective factors that have contributed to the progress of successful African American men in hopes of aiding others in their community in overcoming risks and embarking on a more successful path.
Comparative analysis of chemical composition and in vitro digestibility of Bt versus non-Bt cotton crop residues in Gezira State, Sudan

The objective of the experiment was to investigate and qualify chemical composition of both Bt and non-Bt cotton crop residues (CCR). The in vitro digestibility of each type of CCR was also determined. Week zero represents the period before introduction of animal to graze on Bt-CCR. From each square meter of 14 square meter cotton residues were cut at 10 cm above the ground level. The components of the crop residues in each square meter were separated in to leaves, bolls and tender branches and then weighed freshly and again after drying in an oven at 105◦C for 24hours. The results revealed significant differences in chemical composition of whole residues, in vitro digestibility of dry matter and in vitro digestibility of protein in Bt CCR. Crude protein and ash were higher in all components of Bt CCR and crude fiber was higher in bolls only. The in vitro digestibility showed lower levels in Bt CCR than in non-Bt CCR.
Genetic algorithm-based drilling burr minimization using adaptive neuro-fuzzy inference system and support vector regression

Burrs are undesirable materials beyond the work piece surface during drilling or other machining processes, thus this should be as less as possible during manufacturing. The experimental study has been conducted according to the full factorial design method. A total of 27 experiments were conducted by drilling on an Aluminum 6061T6 plate by choosing three factors and three levels of process parameters like drill diameter, point angle and spindle speed. In this research article, two predictive models, namely, adaptive neuro-fuzzy inference system and support vector regression, are developed using experimental data to estimate burr height and burr thickness. Then, these predictive models have been used to find out optimum process parameters for minimum burr height and burr thickness using genetic algorithm. It has been found that both the models are able to predict burr size and thickness with good accuracy, while the adaptive neuro-fuzzy inference system performs better than support vector regression.
FAKE REVIEWS DETECTION BASED ON BOTH THE REVIEW AND THE REVIEWER FEATURES UNDER BELIEF FUNCTION THEORY

The online reviews play an increasingly spreading role in consumer purchasing decisions and they are also considered as one of the most powerful source of information for companies. Due to this attraction, manufacturers and retailers rely on spammers to promote their own products and demote the competitors’ one by posting fake reviews. Therefore, it is essential to detect deceptive reviews in order to ensure customers confidence and to maintain companies' fair competition. To tackle this problem, we propose a new approach able to spot spam reviews relying both on the rating reviews and the different spammers' indicators under the belief function framework. This method treats uncertainty in the given reviews also in the reviewers' information to take into account each reviewer spamicity when making decision. Experiments are conducted on two real-world review data-sets from Yelp.com with filtered (spam) and recommended (non-spam) reviews to demonstrate our method the effectiveness.
The Determinants of Paternal and Maternal Involvement in Childcare

This study tests the hypotheses derived from three theoretical approaches to the determinants of parents’ involvement in childcare: economic and structural models, gender ideologies, and family systems theory. Two hundred and thirty-seven Israeli couples with three 40-month-old infants completed self-report questionnaires that measured the father’s and the mother’s socio-demographic and employment characteristics, gender ideologies, relationship quality and various forms of involvement in childcare. The findings provided evidence for a structural model, showing that fathers’ childcare hours were negatively related to the degree of overlap between the parents’ work hours. Partial support was also found for the gender ideology model, as the mother’s gender attitudes correlated with her hours of care and the distribution of childcare tasks. Weak support was found for the family systems theory. The findings highlight the importance of distinguishing different forms of involvement in childcare as each is affected by a different set of determinants.
Synergistic treatment of lung cancer with genetically modified cell therapy and chemotherapy

Lung cancer and malignant pleural mesothelioma (MPM) carry a high mortality. Conventional therapies are ineffective in their treatment and there is a need to develop novel therapies. Tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) is a pro-apoptotic agent that triggers the extrinsic death pathway selectively in cancer cells. Mesenchymal stem cells (MSCs) are a type of bone marrow-derived stem cell that have been widely shown to home to and to infiltrate areas of the tumour microenvironment. This homing capacity can be exploited to deliver pro-apoptotic agents, including TRAIL, straight into the tumour micro-environment. Earlier studies show cancers can be treated with TRAIL-expressing MSCs (MSC-flT cells). However, some cell lines are resistant to MSC-flT cells. This study aimed to increase the efficiency of tumour cell killing using MSCs that are engineered to express TRAIL. This study investigates if cancer cell-killing by MSC-flT cells could be enhanced for the treatment of TRAIL-resistant cancers. The aims of this study were to increase the tumour cell-killing efficiency of MSCs engineered to express TRAIL by identifying whether the full-length or soluble form of TRAIL expressed by MSCs is superior in tumour cell killing, whether cancer cell-killing by MSC-flT cells can be increased by combining them with novel chemotherapeutic agents and to identify a biomarker to predict sensitivity to TRAIL. Cancer cell-killing by MSCs expressing full-length TRAIL was superior to that of MSCs expressing the shortened soluble form of TRAIL. MSC-flT cells showed a synergistic cancer killing affect when combined with novel chemotherapeutic agents. In collaboration with McDermott’s laboratory in the Wellcome Trust Sanger Institute, it was found that BAP1-mutated MPM cells are sensitive to TRAIL. This was validated by knock-in and knockdown experiments. It was shown that BAP1-mutated tumours are sensitive to TRAIL in vivo. Further work was done to delineate the mechanism of BAP1-induced TRAIL resistance. The deubiquitinating function of BAP1 and its nuclear localization were shown to be required for TRAIL resistance. This indicates that loss of function of BAP1 is a biomarker for TRAIL sensitivity.
MODEL PENGELOLAAN SAMPAH PERKOTAAN (Survey Pada Pengelolaan Persampahan Kota Bogor)

Konsekuensi dari tingginya peningkatan jumlah penduduk di kawasan perkotaan adalah peningkatan volume timbulan sampah sebagai dampak dari aktivitas dan konsumsi masyarakat. Keterbatasan lahan untuk TPA sampah di kawasan perkotaan mendesak pemerintah kota untuk berinovasi mengurangi timbulan sampah mulai dari sumbernya. Pengomposan sampah merupakan salah satu cara yang efektif karena sebagian besar kandungan sampah rumah tangga adalah bahan organik. Namun pengolahan sampah yang tidak sesuai dapat menimbulkan masalah kesehatan, dampak lingkungan, dan dampak sosial. Kondisi ini mengindikasikan bahwa pemilihan model pengolahan sampah menjadi komplek karena dipengaruhi oleh multikriteria serta adanya hubungan keterkaitan antar subkriteria. Analytic Network Process (ANP) merupakan suatu metode yang dapat digunakan untuk memodelkan permasalahan dengan menggunakan hubungan keterkaitan antar kriteria. Penelitian ini mengidentifikasikan 15 subkriteria dalam 5 kriteria (ekonomi, lingkungan, social, teknik dan pemasaran).

Total phenolics, antioxidant capacities and pomological characteristics of 12 apricot cultivars grown in Turkey

In this study, pomological analyses and antioxidant capacity and total phenolic compound content assessments of fruits sampled from 12 apricot cultivars commonly cultivated in Turkey. Significant differences between the cultivars were determined in terms of evaluated traits. Antixodant capacities varied between 0.62 and 1.18 μmol TE/g FW, and total phenolic contents were found between 351.83 and 1208.33 μg GAE/g FW among the cultivars. The results of the study were concluded to be beneficial for apricot breeders who are willing to conduct breeding studies to improve related traits by the help of the related cultivars, and also for apricot fruit consumers in selecting higher phytochemical content cultivars.
The Role of Hedonic and Utilitarian Motives on the Effectiveness of Partitioned Pricing

Abstract The present research investigates how purchase motives (hedonic vs. utilitarian) influence the effectiveness of partitioned versus combined pricing. Across four studies, we find that compared to combined pricing, partitioned pricing increases hedonic purchases, but not utilitarian purchases. We find this happens because consumers considering a hedonic purchase tend to feel anticipated guilt associated with their hedonic spending, and partitioned pricing is used as a guilt-mitigating justification for the spending. Specifically, consumers with a hedonic purchase motive underprocess a surcharge, which enables them to perceive the price of the product as lower than the actual, combined price. This lower price perception helps consumers justify their hedonic purchase as an act of saving money, and as a result, alleviates guilt. These effects are magnified among consumers who have high disposition to feel consumption guilt. When a price discount is offered, it attenuates the effectiveness of partitioned pricing because the price discount serves as a more effective justification by offering actual saving, not just the perception of saving. Our findings contribute to the pricing literature by uncovering a motivational factor influencing the effectiveness of partitioned (vs. combined) pricing, and offer a useful pricing guideline to product managers based on the product-pricing fit revealed in our research.
Increasing hookah use among adolescent females in the US: analyses from the 2011-2014 National Youth Tobacco Survey (NYTS)

INTRODUCTION The use of hookah (waterpipe) is increasing rapidly among US adolescents, nearly doubling from2011-2014. Further information is needed about characteristics of those who use hookahs and how key characteristics associated with use may be changing. METHODS Data from the nationally representative 2014 National Youth Tobacco Survey (NYTS), n=22,007, were analyzed to determine adolescents’ characteristics independently associated with use of hookahs, using bivariate and multivariate analyses. Additionally, NYTS 2011-2014 data were analyzed to investigate changes in prevalence of hookah use over time, by sex. RESULTS Among adolescents in 2014, female sexand past 30-day use of cigarettes or e-cigarettes were each independently associated with higher odds of past 30-day use of hookahs (AOR=1.41, 95% CI1.15-1.72; AOR=4.01, 95% CI3.19-5.05; AOR=6.85, 95% CI 5.29-8.88, respectively). Hispanic adolescents (AOR=1.91, 95% CI 1.51-2.42) and adolescents who live with someone who uses hookah (AOR=8.56, 95% CI 6.02-12.18) had greater odds of past 30-day use. From 2011 to 2014, use among males and females increased, with a percent change of 87% for males (1.60% to 2.99%) and 175% for females (1.21% to 3.33%). CONCLUSIONS These data demonstrate the magnitude of adolescent hookah use, particularly among adolescents who use electronic or traditional cigarettes. Most strikingly, rates of female adolescent use have increased much more rapidly than has male use, and adolescent females are for the first time more likely to smoke hookahs than adolescent males in the US nationwide. These findings urgently call for better understanding of the changing correlates of hookah use, including polytobacco use.
Application of Enteromorpha polysaccharides as a new coagulant aid to remove silver nanoparticles: role of dosage sequence and solution pH

Silver nanoparticles (AgNPs) in surface water cause a serious threat to the health of humans and aquatic organisms. However, it is difficult to remove AgNPs completely since they could adsorb onto the surface of humic acid (HA) and meanwhile release Ag+ into water. In this paper, Enteromorpha polysaccharides (Ep) were applied as a coagulant aid with polyaluminum chloride (PAC) to solve this problem. The influences of Ep dosage, dosing sequence and solution pH on the coagulation efficiency, kinetics and removal mechanism of AgNPs were discussed systematically. Results showed that when Ep was applied, AgNPs could be removed effectively due to charge neutralization of PAC hydrolysate and the bridging-sweeping role of Ep gel network. When Ep was added 30 s after PAC dosing, the coagulation efficiency was about 10–20% higher than that of the reverse order. Under this condition, flocs sizes achieved 450 μm when the solution pH was 6.0, which is much larger than that using Ep–PAC. Additionally, Ep showed an ability to promote the re-aggregation of broken flocs, and AgNP–HA flocs exhibited larger sizes, better shear resistance, higher recovery ability and denser structure at pH 6.0. Factorial analysis results indicated that PAC dosage had the greatest impact on HA and AgNP removal, while Ag+ removal is more sensitive to Ep dosage.
Hypnosis is a Surgical Pain Intervention: A Systematic Review

Surgery is a medical procedure that can cause perioperative pain. Pain in the perioperative phase that received by the patient can cause various complications. Hypnosis is a part of complementary and alternative therapies that are able to cope with pain. The purpose of the review is to perform a systematic review of the literature. Hypnosis is a part of complementary and alternative therapies that are able to cope with pain in surgery. A comprehensive article search through EBSCO, PROQUEST, and Scopus, the original article was sought in the period of publication between 1999 and 2019. The original articles reported on the effectiveness of hypnosis with surgical patient inclusion criteria. A total of 1994 studies have been identified in the literature search. However, only 27 studies were eligible for analysis in this study. The instruments used were visual analogue scale and numeric rating scale questionnaire were used to identify the level of pain in the study. The outcome revealed that hypnosis can decrease level of pain in each perioperative phase significantly. Further research needs to be done to add strong evidence about the use of hypnosis for perioperative pain management.
Light-Based External Human Machine Interface: Color Evaluation for Self-Driving Vehicle and Pedestrian Interaction

In today’s road traffic pedestrians seek eye contact with drivers to move along safely. Such communication is no longer possible with self-driving vehicles. Previous research shows that an external Human-Machine-Interface (eHMI) provides an interface between self-driving vehicles and pedestrians. However, recommendations for standardization are still being developed. The study compares the colors white and turquoise for eHMI lamps indicating that the automated driving system is engaged. The colors are evaluated in a street-crossing scenario and a parking lot scenario with a Wizard-of-Oz vehicle equipped with eHMI lamps mounted on top of the vehicle. We conducted questionnaires and structured interviews with N=59 participants to identify eHMI design guidelines. Our research provides evidence that turquoise facilitates pedestrians’ factors like visibility, discriminability, sense of safety and trust higher than white. The results are consistent among traffic scenarios. This paper contributes in formulating research-based design guidelines to improve pedestrian safety.
Effects of steroidal implants on feedlot performance, carcass characteristics, and serum and meat estradiol-17β concentrations of Holstein steers

Abstract The objectives of the study were to determine the effect of steroidal implants on growth performance, carcass characteristics, and estradiol-17β (E2) concentrations in the blood and longissimus muscle of Holstein steers fed a grain-based diet. Seventy Holstein steers (average initial BW = 275 ± 6.4 kg, 10 to 12 mo of age) were assigned to treatments: (i) implanted with 80 mg of trenbolone acetate (TBA) and 16 mg of E2 (Component TE-IS with Tylan; Elanco Animal Health, Greenfield, IN) at the start of the trial (day 0), and reimplanted with 120 mg of TBA and 24 mg of E2 (Component TE-S with Tylan; Elanco Animal Health) on day 84 of the experiment; or (ii) no implant. Implanted Holstein steers were heavier (P ≤ 0.01) than nonimplanted Holstein steers in the middle (day 84) and at the end of the experiment (day 186). Implanting Holstein steers increased (P < 0.01) average daily gain (ADG) and dry matter intake (DMI) without affecting gain-to-feed ratio compared with nonimplanted animals. Carcasses from implanted Holstein steers had greater (P < 0.01) hot carcass weight (HCW) and longissimus muscle (LM) area than carcasses from nonimplanted steers. Implanting did not affect (P ≥ 0.21) other carcass characteristics. There was an increase (P = 0.03) of 1.3 pg of E2/g of muscle in implanted Holstein steers compared with that from nonimplanted Holstein steers. There was an implant × day interaction (P < 0.01) in serum E2 concentrations. Serum E2 concentrations were not altered in nonimplanted Holstein steers, whereas E2 concentration increased (P < 0.01) after steers were implanted, regardless of implant characteristics. Serum E2 peaked at 28 days after the first implant and then rapidly declined after day 56. In summary, steroidal implants administered on days 0 and 84 increased DMI, ADG, HCW, and LM area in Holstein steers compared with nonimplanted steers due to increased serum E2 concentrations. However, these changes did not improve feed efficiency or other carcass characteristics.
Clinical Image Analysis for Detection of Skin Cancer Using Convolution Neural Networks

Humankind, since the growth of its civilization past the industrial revolution, has been a witness to an exponential rise in the number of causes and fatalities of unprecedented deaths. Despite having a humongous growth of technology since the late 80’s, researchers and doctors have not been able to fully develop cutting-edge technology that could play a crucial role in reducing life-threatening cases of diseases around the world. Diagnosis of the disease requires a high level of precision and expertise in a variety of visual aspects. Technology in the field of Medical Science has been successful in achieving unprecedented heights and has played a major role ranging from medical assistance to automation in surgeries. Machine Learning technologies have dominated by having a positive endeavor towards detecting life-long diseases at an early stage. Deep Learning has played an important role in this domain to give doctors and research scholars unimaginable assistance in predicting cancerous cases. This paper suggests an implementation of a CNN model being malignant or benign. Since the dataset was quite imbalanced, the proposed method applies Gaussian filtering over the sample images and then processed it. We have proposed an architecture named “Adnet” that has a particular recursive flow of layer networks which provides better accuracy than the pre-existing models Figure 1.
