Published: December 2019

Abstract
This study aims to determine whether the mathematics learning outcomes of students who use cooperative learning models of the Think Pair Share type are better than the mathematics learning outcomes of students who follow conventional learning models. Hypothesis testing is done by using data analysis techniques with the t-test formula. Previously the data was determined by the average and standard deviation of each class, then a normality test was performed using the Lilliefors test, the results for the experimental class Lo = 0.092 with Ltabel = 0.1498 and the control class Lo = 0.1008 with Ltabel = 0.1477 so the samples come from populations with normal distribution. The analysis was continued by testing the similarity of variance. It turns out that both samples have a homogeneous variance. After the t-test is tested, the price of t count = 2.95, while the price of t table = 1.67. Because t-test > t table at the real level = 0.05, it can be concluded that the mathematics learning outcomes of students using the cooperative learning model think pair share are better than the mathematics learning outcomes of students who use conventional learning in the XI science class MAN 2 Padang.

Abstract
Lift-net (local term: Bagan Rambo) is one of the most productive fishing gear in the coastal community of Gulf of Bone, including those in the Bone District. This study aims to explain the characteristics of the marketing channels of frigate tuna caught by fishermen and the effectiveness and efficiency of frigate tuna market system. The study was conducted from December 2017 to February 2018 at Bone District, South Sulawesi Province-Indonesia with a purposive sampling method of 37 units of lift-net and 481 fisheries households. The results of the study show that lift-net owners and fishmongers are the main channels of catch marketing (66.7%). For Bone sub-district of Tanete Riattang Timur 50% of catches go fishing auction and fisheries companies. The effective marketing system of frigates tuna are: 1) fishermen get more profit if they sell their catch in kg instead of selling per bucket, 2) the boat owner and fishmonger get a big profit, at the sale of a minimum price. The effective marketing channel is directly selling catches to fisheries companies.

Abstract
Although 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) scan has been generally validated in the staging of malignant pleural mesothelioma (MPM), its diagnostic and prognostic performances are not clearly established. Aiming to identify possible factors causing 18F-fluorodeoxyglucose PET/CT false-negative results and influencing prognosis in MPM patients, we analysed clinical, radiometabolic and pathological features in 141 MPM patients who underwent diagnostic 18F-fluorodeoxyglucose PET/CT scan (January 2009–July 2018) at 2 high-volume institutions. The Fisher’s exact test and the Cox model were used in statistical analysis. Overall detection rate was 88.3% with 16 patients (11.6%) presenting with a standardized uptake value (SUV) max &lt;2.5 (PET-negative). PET-negative cases were more frequently detected in older patients (P = 0.027) and early-stage tumours (33.3% false-negative in stage I and 40.0% false-negative in T1-tumours, with P = 0.014 both). Mean SUVmax value was higher in sarcomatoid (11.8 ± 4.6) and biphasic MPM (9.3 ± 7.0), rather than in epithelioid MPM (6.9 ± 3.8, P &lt; 0.001). Concerning overall survival, SUVmax (both as continuous and as categorical variable) was found to be a prognostic factor, in addition to stage (P = 0.032) and histology (P = 0.014) as confirmed by multivariable analysis (hazard ratio 2.65, confidence interval 1.23–5.70; P &lt; 0.001). In the light of such results, we highlight that a low fluorodeoxyglucose uptake might be observed in more than 10% MPMs, especially in early-stage tumours affecting elderly patients. Furthermore, high SUVmax values significantly correlated with a worse prognosis.

Published: December 2019

AbstractThis paper is concerned with the approximate controllability of semilinear impulsive functional differential systems in Hilbert spaces with non-local conditions. We establish sufficient conditions for approximate controllability of such systems via resolvent operator and Schauder’s fixed point theorem. An application involving the impulse effect associated with delay and non-local conditions is presented to verify our claimed results.
Impact of Changes in Detection Effort on Control of Visceral Leishmaniasis in the Indian Subcontinent

Published: December 2019

Abstract

Background
Control of visceral leishmaniasis (VL) on the Indian subcontinent relies on prompt detection and treatment of symptomatic cases. Detection efforts influence the observed VL incidence and how well it reflects the underlying true incidence. As control targets are defined in terms of observed cases, there is an urgent need to understand how changes in detection delay and population coverage of improved detection affect VL control.

Methods
Using a mathematical model for transmission and control of VL, we predict the impact of reduced detection delays and/or increased population coverage of the detection programs on observed and true VL incidence and mortality.

Results
Improved case detection, either by higher coverage or reduced detection delay, causes an initial rise in observed VL incidence before a reduction. Relaxation of improved detection may lead to an apparent temporary (1 year) reduction in VL incidence, but comes with a high risk of resurging infection levels. Duration of symptoms in detected cases shows an unequivocal association with detection effort.

Conclusions
VL incidence on its own is not a reliable indicator of the performance of case detection programs. Duration of symptoms in detected cases can be used as an additional marker of the performance of case detection programs.
In vitro effects of combined iron chelation, antibiotics and matrix disruption on clinical isolates of Pseudomonas aeruginosa
Authors: Nair Arun , Perry Audrey , Perry John D , Gould F Kate , Samuel Julie 
Published: December 2019

Abstract

Objectives
Pseudomonas aeruginosa is an important pathogen in chronic suppurative respiratory diseases, with adverse effects on severity, healthcare utilization and quality of life. Aerosolized combined biofilm disruption and iron chelators offer novel proof-of-concept for improving airway antimicrobial efficacy. Our aim was to assess the activity of desferrioxamine, Dornase alfa (DNase) and antibiotics on biofilm formation and against mature preformed biofilms of P. aeruginosa.

Methods
Fifty-six isolates of P. aeruginosa were screened for biofilm production and seven isolates with varying capacity to form biofilms were referred for further study. Three antibiotics (colistin, tobramycin and ciprofloxacin) as well as desferrioxamine and DNase were assessed for their ability to prevent biofilm formation using the crystal violet assay. The same method was used to assess their impact on mature biofilms. Each agent, as well as combinations of these agents, was also assessed for its effect on the metabolic activity and viability of preformed P. aeruginosa biofilm by the resazurin reduction assay and by performing viable counts.

Results
Antibiotics alone prevented the development of biofilms and partly reduced the viability of mature biofilms. Desferrioxamine and DNase did not reduce biofilm formation. For most isolates, desferrioxamine and DNase did not offer any clear advantage over the use of antibiotics alone with respect to reducing the viability of Pseudomonas biofilms.

Conclusions
Colistin, tobramycin and ciprofloxacin prevented biofilm formation by P. aeruginosa and reduced the viability of mature biofilms. For most isolates, there was no clear advantage of combining these antimicrobials with desferrioxamine or DNase.
Cyprid larvae of the acorn barnacle Semibalanus balanoides (Linnaeus, 1767) (Cirripedia: Sessilia: Archaeobalanidae) can metamorphose to juveniles without being permanently attached to a substrate

Published: December 2019

AbstractIt is commonly assumed that the pelagic cyprid larvae of acorn barnacles must permanently attach to a substrate before metamorphosing to the benthic juvenile stage. We show that this is not always the case and demonstrate that some cyprids can metamorphose in the water column, i.e. without first becoming cemented to a surface. We observed early-metamorphosing cyprids to fully developed juveniles in coastal plankton samples during the 2018 recruitment season of Semibalanus balanoides (Linnaeus, 1767) in Atlantic Canada. We demonstrated through a laboratory experiment that cyprids can be induced to fully metamorphose into pelagic juveniles. These novel findings raise the question of whether this phenomenon may also occur in other barnacle species.
