Proficient bilingualism may alleviate some executive function difficulties in children with Autism Spectrum Disorders
Authors: Nadig Aparna , Gonzalez-Barrero Ana Maria 
Published: June 2019

Abstract
A bilingual advantage, or enhanced performance on executive function (EF) tasks, has been identified in typically-developing bilingual children relative to monolinguals. Children with Autism Spectrum Disorders (ASD) demonstrate significant EF difficulties in comparison to typically-developing peers. Perhaps bilingualism could alleviate EF impairments in ASD? We review our lab’s findings from bilingual vs. monolingual school-age children with ASD, and those with typical development, on both performance tasks and parent ratings of EF application in daily life. We present the first evidence of a bilingual advantage in ASD on EF performance tasks (verbal fluency and dimensional change card sort), but not parent ratings. The implications of these preliminary findings for future research and clinical practice with children with ASD and other neurodevelopmental disorders are discussed.

Published: June 2019

Verbs play an essential role in enabling sentences to be interpreted rapidly in real time. The objective of this work is to investigate how verb information is used during real-time comprehension of sentences in Spanish. Twenty-five children (aged 5.3–8.2 years) with specific language impairment (SLI), fifty typically developing children (aged 3.3–8.2 years), and thirty-one normal adults participated in three eye-tracking experiments involving spoken language comprehension. Participants listened to simple sentences in the presence of four depicted objects, only one of which satisfied the semantic restrictions of the verb. Eye movements revealed that children with SLI were able to recognize and retrieve the meaning of the verb rapidly enough to anticipate the upcoming semantically appropriate referent.
A Combined Finite-Element-Finite-Volume Method for Thermal Arc Numerical Simulation
Authors: Abdo Youssef , Rohani Vandad , Cauneau François , Fulcheri Laurent 
Published: June 2019

Abstract

Most of the numerical methods used for thermal arc simulation, are often based either on finite volume or finite element approaches but very seldom on both of them. In this paper, we present a new combined finite-element finite-volume method for stationary and unsteady cases. The flow, energy and species equations are solved using a classical finite-volume (FV) method which is conservative and bears a robust physical meaning. The electromagnetic equations (EM) are solved using finite-element (FE) analysis which has the ability to easily deal with their mathematical formulation without transforming the equations or doing any extra manipulation. We propose two separate approaches for the FE-method: one that is only suitable for a steady-state scheme and another that could be applicable for both steady and unsteady cases. Some illustrative numerical examples are also presented in this paper.

Published: June 2019

Abstract
A global integral model of an arc discharge in helium with sputtered composite metal-graphite anode is presented. The arcing time was measured experimentally for different elements and mass fractions of the metal additions to the graphite anode. The obtained calculated results for pure graphite anode show a good agreement with the experimental and calculated data of other authors. In particular, a good correspondence between the absolute values of electron density and temperature, the discharge voltage and the anode ablation rate as a function of the discharge current was shown. The obtained in the work experimental and calculated data have qualitative agreement, i.e. the anode erosion velocity increases with the addition of Zr, and decreases with the addition of Al.

Published: June 2019

Abstract
The production and price of citruses in the Parbuluan IV Village were very fluctuating. The citrus production has dropped dramatically from 2014 until 2016. From the productions and price, it is known that there is a probability of risk in this area. The purpose of this study was to analyse the types of risks faced by citrus agribusiness actors and analyse the value of risk probability and its effect on citrus agribusiness actors in Parbuluan IV Village. The method to determine the research area used was the purposive sampling method so that the research was conducted in Parbuluan Village IV. Parbuluan Village IV was chosen because the productivity of citrus was decreasing in recent years and the price selling of citruses at the farmers level had not comparable with the price selling of citrus at the consumers level. The results showed that the risks faced by agribusiness actors consist of internal risks and external risks. The probability value of production risk of 57.14% means that the chance of risk to occur is high and the probability value of price risk of 46.02% means that the chance of risk to occur is low.
Is irrigated farm more efficient than non-irrigated no-tillage farm and non-irrigated conventional farm for a sample of Kansas corn farmer?
Authors: Wibowo R P 
Published: June 2019

AbstractThe corn farmer has benefited from high corn price. However, the corn price falls from its high price in 2012 to as low as $ 4.46 per bushel in 2013. The drop in corn price and intense competition from the global grain markets make farms that are non-efficient struggle economically. Pure technical, overall, allocative and scale efficiency were measured to analyze the competitiveness of a sample of Kansas corn farmers. Farmers increased their relative efficiency during drought in 2012. Government payment was found to be negatively correlated with efficiency for non-irrigated farms. Interest expenditure might have negative impact on input allocation for irrigated and non-irrigated conventional farms. Irrigated farms should focus on increasing acreage land to increase overall efficiency. On the other hand, non-irrigated conventional farm should focus their effort to enhance overall efficiency by increasing seed inputs.
Climate Change Adaptation Strategies for In-field Conservation Practices by Irrigated Farm
Authors: Wibowo R P 
Published: June 2019

Abstract
Irrigated farmer is less adaptable to conservation practice. Total precipitation has positive significant impact on adoption of terrace conservation practices both in Bivariate and Univariate Probit model. Farmer who buys insurance is found to be less likely to adopt the terrace conservation practice. The temperature from May to July is still favourable for corn growth which causes not significant impact on temperature to conservation practice adaptation.

Authors: Pandia S , Setiawan A , Sanjaya N , Haryanto B 
Published: June 2019

Abstract
The activated mango seed was used to reduce FFA (Free Fatty Acid) and PV (Peroxyde Value) content in CPO (Crude Palm Oil). This study was begun with biosorbent modification. With size 140 mesh, 1% biosorbent of CPO with 35 minutes contact time, and shaking speed 200 rpm shown that the FFA and PV reduction percentage were 28.97% and 51,6%. The surface layer interaction model results follow Freundlich isotherm. The R2 of kinetics equation model results are 0.9879 on FFA adsorption and 0.9923 on PV adsorption. This model involves the assumption that the pore surface of the biosorbent is different or heterogeneous. The Freundlich Isotherm model is also based on the assumption that there is a pore size distribution on the adsorbent and is applicable to more than one surface layer (multilayer) adsorbed by biosorbent. The ability of activated mango seed to adsorb more organic compound shows its potential as an alternative for bleaching earth substitute.

Published: June 2019

Abstract
Peatland clearance and drainage result in the change of anaerobic to aerobic condition and hence microbial activities that increase CO2 emission. This study aimed to evaluate the rate of microbial respiration and microbial population from sapric and hemic peat under oil palm plantation. Research activities included measurement of soil respiration using potassium hydroxide (KOH) to capture the respired CO2, and counting the population of microbes. Results of this study showed that the highest rate of respiration of 3.3 ± 0.8 mg CO2 100 g−1 day−1 occurred from the 0-20 cm layer and it decreased to 2.1 ± 1.0 mg CO2 100 g−1 day−1 from the 20-40 cm layer and 1.2 ± 0.9 mg CO2 100 g−1 day−1 from the 40-60 cm layer in sapric peat. For the hemic peat the highest rate of respiration of 3.1 ± 0.4 mg CO2 100 g−1 day−1 occurred from the 0-20 cm layer and it decreased to 2.0 ± 0.7 mg CO2 100 g−1 day−1 from the 20-40 cm layer. Soil respiration decreased with peat depth and bacteria were the most dominant microbes in each peat depth, indicating that bacteria play a more important role in respiration than other microbes.

Abstract
Nutmeg seed is an herb containing antimicrobial compounds and can be applied as an antimicrobial on foodstuffs. This study was aimed to know antimicrobial compounds of nutmeg seed extracting in water, methanol, ethyl acetate and hexane. Assay on the extract to inhibit pathogenic microbes (Staphylococcus aureus, Escherichia coli and Bacillus cereus) was conducted using dilution method. Phytochemical test was conducted to know the extract compounds. Minimum Inhibitor Concentration (MIC) test was measured to know minimum concentration of the extract to be applied in tempeh sausage. The results showed that nutmeg seed extract contained alkaloids, flavonoids, steroids, saponins, tannins and phenolics. Methanol extract was shown to have higher inhibition to the tested microbes compared to the other extracts. Minimum Inhibitor concentration (MIC) occurred at concentrations of 0.1% and 0.25% of nutmeg seed extract on Staphylococcus aureus and Escherichia coli. Nutmeg seed extract added on the tempeh sausage was able to reduce total microbial cell up to 5 days of storage compared to that of the control, i.e. 561x104 CFU/g for control, 61x104 CFU/g for 0,1% nutmeg seed extract and 54x104 CFU/g for 0,25% nutmeg seed extract.
