Involvement of STK and REM24 in cellular specification during ovule formation in Arabidopsis thaliana

The European consortium SEXSEED was conceived to increase the knowledge on seed development. Its main goal is to assemble the regulatory network controlled by SEEDSTICK (STK). STK is a transcription factor (TF) responsible for specifying the identity of Arabidopsis thaliana ovules. Recently, it was revealed that STK may be implicated in megaspore mother cell (MMC) identity, although it is never expressed in that cell. stk ovule primordia show enlarged sub-epidermal nucellar cells resembling the MMC. The work here presented intends to demonstrate STK’s involvement in this process. Transcriptomic data obtained from stk inflorescences, the wild type MMC and the wild type nucellus were used to obtain a list of genes putatively regulated by STK, important for the cross talk between the nucellus and MMC. Among all the genes, REPRODUCTIVE MERISTEM 24 (REM24) was found as an interesting putative STK target. In fact, previous studies demonstrated that another REM TF, VERDANDI, is a STK direct target. REM24 was studied using a multistep approach: the ovule development of rem24 was characterized; to determine the expression pattern of the candidate gene, a marker line was developed; the molecular pathways affected in rem24 were evaluated by qPCR. Since the identity of such enlarged nucellar cells was never investigated in stk, the defects in ovule development in both stk and rem24 were further investigated using aniline blue staining, immunolocalization of AGP and callose epitopes, and by crossing the mutant plants with relevant marker lines. Remarkably, the molecular assessment of stk seems to indicate that SPOROCYTELESS can be involved in the formation of enlarged nucellar cells. Additionally, it was also revealed that ARGONAUTE9 and RNA DEPENDENT RNA polymerase 6 are potentially regulated by STK, showing its potential control over epigenetic mechanisms important in the nucellus-MMC cross-talk.
The impact of sleep quality and duration on college student adjustment and health

College years are a time of change and transition that involves complex challenges in academic, social, personal/emotional, and institutional adjustment. Stress, anxiety, and tension are often associated with college transition and adjustment; stress and worry have been related to poor sleep quality. Studies have found that college students have more sleep problems than the general public. Research has shown that poor sleep has adverse effects on cognition, mood, and other physiological and psychological aspects o f human functioning. Recent research has indicated that sleep quality may be more important than amount o f sleep. Relationships have been found between sleep problems and various psychological difficulties and cognitive deficits in college students. Research suggests that sleep problems can have detrimental effects on various components o f college adjustment. However, studies examining the relationship between sleep and dimensions o f college adjustment are limited. The purpose o f the present study was to examine the relationship between college students’ sleep quality, their adjustment to college, and their physical/mental health. The relationship between sleep quality and college adjustment was assessed using the Pittsburgh Sleep Quality Index, the Sleep Quality Index, a sleep habits questionnaire, and the College Adjustment Scales (CAS). The relationship between sleep quality and general physical/mental health was assessed
Heat capacity of endohedral fullerenes Rg@C60 (Rg = He, Ne, Ar and Kr)

ABSTRACT The heat capacity of rare gas containing endohedral fullerenes has been computed by computing the vibrational frequencies of the molecules using the Hartree–Fock method and the density functional theoretic method with the wB97XD functional and the 6-31G* basis set. The consequences of the translational motion of the rare gas atom becoming vibrational motion inside the fullerene cavity are examined by comparing the computed vibrational frequencies for fullerene and the endohedral fullerenes. The increase in the heat capacity of the endohedral fullerenes due to encapsulation is interpreted in terms of the bound states of a three dimensional isotropic harmonic oscillator.

Evaluating Intra- and inter-rater reliability for "Cleft palate speech assessment test based on universal parameters system- in Persian"

Introduction: Cleft palate is one of the most common congenital birth defects. Individuals with cleft palate have certain speech characteristics that can be identified perceptually by speech-language pathologists. Perceptual assessment has been regarded to as the gold standard for evaluating cleft palate speech. Considering the prevalence of cleft palate and its related speech characteristics, it is necessary for clinicians to use a reliable test for perceptual assessment of cleft palate speech errors. The aim of this study was to evaluate Intra- and inter-rater reliabilities for a recently developed assessment tool named "Cleft palate speech assessment test based on universal parameters system– Farsi version". Materials and Methods: In this descriptive-analytic cross-sectional study, speech samples obtained from 34 five-to-nine-year-old Farsi-speaking children with cleft palate who were referred to Isfahan cleft palate clinic were rated by two speech-language pathologists (one of them was considered as a naive and the other one as an expert rater). Two months later, 30% of the same speech samples were randomly selected and rerated by the same raters. Speech materials included 40 single words and 17 sentences along with a sample of connected speech. Intra- and inter-rater reliability measures were calculated via Intraclass Correlation Coefficient (ICC). Results: Mean Intra-rater reliability measured by ICC was found to be 0.967 and 0.971 for the naive and expert raters respectively. Mean Inter-rater reliability was 0.957 as measured by ICC. Conclusion: This test has an acceptable Intra and inter-rater reliability to be used in assessment of cleft palate speech and can be applied in those studies aimed at evaluating different aspects of speech in Farsi-speaking children with cleft palate aged from 5 to 9 years.

Optimum Utilization of Biochemical Components in Chlorella sp. KR1 via Subcritical Hydrothermal Liquefaction

Product distributions in bio-crude, aqueous phase, and solid residue were rigorously analyzed during the hydrothermal liquefaction (HTL) of Chlorella sp. KR1 in order to optimize utilization of energy and chemicals. A non-asphaltene (paraffinic) fraction in the bio-crude, which can be readily upgraded to high-quality fuels via a subsequent catalytic process, was mainly produced due to lipid extraction. Above 170 °C, lipid extraction was almost complete, and hence, the non-asphaltene content did not increase further with increasing temperature. Carbohydrates could be extracted, mainly as polysaccharides, in the aqueous phase at mild temperatures ( 200 °C), they decompose and react with proteins via the Maillard reaction to form asphaltene (polycyclic aromatics), which contains large amounts of heteroatoms such as N and S. Although high-temperature carbohydrate conversion could yield more bio-crude with high energy values, it dominantly contributed to formation of the asphalt.
Enhancing the Removal of Sorbed Crude Oil from Soil Through Multiple Oxidation Steps in Stepwise Fenton Processes

ABSTRACT The stepwise Fenton oxidation process, in which hydrogen peroxide (H2O2) is added in a step-by-step manner instead of at the beginning, can achieve better sorbed crude oil removal effects. The results showed that if a high ratio of sorbed total petroleum hydrocarbon (TPH) was present in soil samples S1 (100%, initial TPH: 10,009 mg/kg) and S2 (94.2%, initial TPH: 4850 mg/kg), the TPH was oxidized in each step. In addition, the total TPH removal efficiency was 49.6% compared with the 27.9% achieved in conventional Fenton oxidation in which all H2O2 was added at the beginning. Nevertheless, when the ratio of sorbed TPH in the soil sample S3 was low (45.3%, initial TPH: 2850 mg/kg), the TPH removal efficiency was 18.9%, which was slightly higher than 18.2% achieved in the conventional Fenton process because if the sorbed TPH concentration was low, the sorbed TPH was mainly removed in the first step. The second and the third step resulted in long-chain alkanes entering the aqueous phase rather than removing them from the soil, which posed environmental risk. Therefore, it is clear that stepwise Fenton oxidation could improve sorbed TPH removal efficiency when the sorbed TPH concentration in the soil is high.

Estimations of the effect of modern ozone absorption cros-ssections data on calculation of the atmospheric transmission and fluxes, measured using Sun photometers in the UV spectral region, are made. The ozone absorption cross-sections, often used in radiative codes, and new data of Serdyuchenko et al. are considered.
Microtiter plate‐based cultivation to investigate the growth of filamentous fungi

Microscale bioprocessing techniques are rapidly emerging as a means to increase the speed of bioprocess design and to reduce material consumption. However, there is still a lack of suitable parallelized techniques to investigate the industrially important group of filamentous bacteria and fungi. Cultivation of filamentous organisms in shake flasks is still the favored technique for comparing and optimizing cultivation conditions of production strains at mL‐scale. In this paper, the application of a microtiter plate‐based cultivation system in combination with the filamentous fungus Aspergillus niger was investigated. A protocol for reproducible cultivation was developed and evaluated. Productivity of A. niger concerning the rose‐like aroma compound 2‐phenylethanol showed low standard deviations while regular and consistent morphologies appeared in the parallelized system. Furthermore, the effect of addition of microparticles on the morphology was investigated. The results can be used to accelerate the process development with A. niger and other filamentous organisms.

Problema de movimentação do carro tripper - comparação de novas políticas.

Operational Research techniques have been incorporated into mining companies to support decision making. According to (BARBOZA, 2005), the Brazilian iron ore sector was one of the sectors that obtained the most significant returns with the application of the technique in its operations. This work addresses a problem present in the process of iron ore processing where there is the use of the tripper car in the distribution of the material between the storage silos. The purpose of this is to develop a new policy of car movement and compare it to the model formulated by (CALDAS, 2018), author who introduced the problem in the literature. The method used is Linear Integer Mixed Programming modeled in Lingo 10.0 software with interaction with MS Excel 2010. Due to the combinatorial nature of the implemented models, the computational time spent in the resolution was excessive and for that reason was limited to one hour of resolution. The work is justified by the lack of literature on the topic addressed and of logics that translate productive strategy efficiently, thus contributing to the competitiveness of mining companies. Sixty instances have been created to implement the models and to allow comparison between processing times and behavior of policy processes.
Synthesis and Applications of Functionalized Magnetic Nanomaterials in Enantioseparation

Efficient enantioselective separation is a challenging task due to the identical physical and chemical properties of enantiomers. Functionalized magnetic nanomaterials modified with chiral ligands on their surface possess both magnetic property and chiral recognition ability, and have demonstrated great potential in chiral discrimination. This review summarizes the applications of magnetic nanomaterials modified with various chiral selectors (e.g., β-cyclodextrins, polymers, proteins, amino acids and cellulose) in enantioselective separation. After proper preparation and modification, these functionalized magnetic nanomaterials are effective for enantioseparation. Therefore, enantioseparations based on functionalized magnetic nanomaterials are convenient, economical and effective.
Experimental Study on the Removal of VOCs and PAHs by Zeolites and Surfactant-Modified Zeolites

Synthetic zeolite Na-X and clinoptilolite (Cp) as well as their modifications with quaternary ammonium salts were used to remove volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs) from aqueous solutions. A novel procedure was developed for the synthesis of organo-zeolites which consisted of surface modification with hexadecyltrimethylammonium bromide (HDTMA) in amounts of 1.0 and 2.0 of external cation exchange capacity (ECEC). Modification of both zeolites with HDTMA improved sorption properties. p-Xylene and dibenz[a,h]anthracene were adsorbed in amounts of 6.82 and 0.65 mg/g, respectively. Ethylbenzene and naphthalene were the lowest-removed hydrocarbons (2.99 and 0.058, respectively). The removal efficiencies for BTEX followed the order p-xylene > toluene > benzene > ethylbenzene, and for PAHs they followed the order dibenz[a,h]anthracene > benzo[a]pyrene > anthracene > naphthalene. Efficiency of sorption depends on the chemical properties of the various organic compounds (d.
Characterization of the organic fraction of pretreated leachate from old landfill after sonication exposure

Collection of municipal waste in landfills, even properly designed and operated, is an important issue in environmental engineering. These are formed by the infiltration of rainfall through the waste bed and eluting with the organic and inorganic compounds, often toxic nature. So far, over 200, have been identified which are organic substances leachate contamination, as many as 35 belongs to the so-called “priority pollutants”. By the decrease in the concentration of organic compounds in the leachate decrease the value of biological and chemical oxygen demand which is dictated by stabilization of landfill as lengthening the time of its life. However, the indicator BOD5 decreases faster as compared to COD therefore BOD5/COD ratio is reduced to as low as 0.06. The leachate produced in mature landfills appears to be the presence of significant amounts of humic acid with very stable structure difficult to breach by bacteria. It was assumed that ultrasonic waves induce change in the structure of organic compounds and contribute to the acceleration of the biodegradability, among other substances in the effluents refractive thereby improve the efficiency of the biological purification processes. For sonification leachate used ultrasonic disintegrator type vibro goal Sonics (40 kHz). The range of vibration amplitude was varied in the range from 25 to 123 μm and exposure time (sonification of leachate) from 60 to 720 seconds. Also the measuring of the size of the energy produced during sonication sonochemical leachate was made. It was found, inter alia, that the sonification process of effluents clearly influenced the formation and release of aliphatic compounds. The –CH2 and –CH3 groups can be released from the humic compounds or aromatic combinations. It was also observed the formation of substantial amounts of compounds with the functional hydroxyl group, which might be derived from alcohols and carboxylic acids. These changes suggested a breach of the chemical structure of organic compounds contained in the leachate, so that, the chemical structure of the formed compounds was more susceptible to biodegradation. The study also determined the effect of ultrasonic field on the evolution of the BOD5 treated leachates and BOD5/COD ratio. The BOD5 sharp increase was observed at the time of sonification of leachate in the range of 60 to 300 s in the whole studied range of amplitudes. This suggests that by the action of the ultrasonic field generated in the effluents of chemical compounds had greater biodegradability.The process confirmed by the change in the ratio of BOD5/COD. The highest value of BOD5 indicator (460 mg/dm 3) was at the time of subjecting the leachate impact of ultrasound using amplitude equal to the size of 25 μm and for the time of sonification equal 300 s. In this case the BOD5/COD factor increased to 0.12, and it was about 26% higher as compared to the value of this indicator for leachate no-sonificated (0.089).
Privacy Preserved Medical Service Provider Selection in Cloud-based WBAN

Continuous health status monitoring of the persons equipped with Wireless Body Area Network (WBAN) is one of the key emerging technologies in the area of e-healthcare. In this technology, WBANs and Medical Service Providers (MSPs) are connected via a cloud infrastructure, where WBAN continuously uploads the present readings of physiological parameters via base station such as smart phone, smart watch, etc. Cloud analyzes the physiological parameters and whenever any medical emergency of the user is detected, it checks the infrastructural parameters including the location information of all MSPs connected to it and finds the most appropriate MSP to handle the medical emergency. This MSP selection task has to be performed efficiently so that the medical treatment of the user can start as early as possible. In the existing works, a trusted third party, namely, trusted authority (TA) actively participates in the MSP selection process, which may take undue advantages. The aim of the work in this paper is to remove the role of TA during MSP selection process. However, TA will participate in the system setup phase such that it cannot obtain any advantage in compromising the MSP selection task. The proposed scheme has been scrutinized through an adversary model and simulated using ProVerif tool to verify the security and privacy.
Discovering Glioma Inhibitors via Chemical-Genetic Screens in Drosophila Cancer Models

Today, there are over 250 drugs being used to cure over 100 different types of cancer. We hypothesize that one of the drugs already being used in cancer treatment will either show positive or negative growth when applied specifically to glioblastoma, a type of brain tumor with poor prognosis. Using the fruit fly, Drosophila melanogaster, and 150 tyrosine kinase inhibitors, we can induce tumors and track their growth in response to the drugs. This would open the doors to researching similarities between drugs present in hundreds of chemical libraries. Additionally, the drugs that prove successful through the screenings could start being used in mammalian and clinical trials in the future.
Deep‐learning based projection of change in irrigation water‐use under RCP 8.5

Stream water‐use is essential for both agricultural and hydrological management and yet not many studies have explored its non‐stationarity and nonlinearity with meteorological variables. This study proposed a deep‐learning based model to estimate agricultural water withdrawal using hydro‐meteorological variables, which projected the changes of agricultural water withdrawal influenced by climate change of future. The relationships between meteorological variables and stream water‐use rate (WUR) were quantified using a deep belief network (DBN). The influences of precipitation, potential evapotranspiration, and monthly averaged WUR on the performance of the developed DBN model were tested. As a result, this DBN with potential evapotranspiration (PET) provided better performances than precipitation to estimate the WUR. The PET of multi‐model scenarios for Representative Concentration Pathways 8.5 would be increased as time goes by, and thus leads to increase WUR estimated by DBN in three basins, located in South Korea during the future period. On the contrary, water availability expected to decrease compared to the current. Therefore, managing water‐uses and improving efficiencies can be prepared for the change in agricultural water‐use by climate change in the future.
A Study on Performance of ML Algorithms and Feature Extraction to detect Malware

In this paper, we studied the way that classify whether unknown PE file is malware or not. In the classification problem of malware detection domain, feature extraction and classifier are important. For that purpose, we studied what the feature is good for classifier and the which classifier is good for the selected feature. So, we try to find the good combination of feature and classifier for detecting malware. For it, we did experiments at two step. In step one, we compared the accuracy of features using Opcode only, Win. API only, the one with both. We founded that the feature, Opcode and Win. API, is better than others. In step two, we compared AUC value of classifiers, Bernoulli Naïve Bayes, K-nearest neighbor, Support Vector Machine and Decision Tree. We founded that Decision Tree is better than others.
Social Media and Personal Branding of Gospel Musicians in Kenya

The paper investigated the influence of social media on personal branding of gospel Musicians in Kenya. The objectives of the study were to establish the forms of social media used for personal branding, to identify the factors influencing the use of social media for personal branding, to evaluate the extent to which social media is used for personal branding and to measure the effectiveness of social media use for personal branding. The study was guided by the self-presentation theory and the perception and visual communication theory. Mixed methods research approach was employed. 25 gospel musicians who topped the charts in the music industry in Kenya in the year 2018 were interviewed and data from their social media sites reviewed. Data was analysed qualitatively and quantitatively. Findings indicate that various social media sites offer differing advantages with regard to personal branding. Some social media platforms like Facebook and Instagram could offer more effective options over others. Most gospel musicians employ social media managers to run their social media sites. Computer literacy, access to smart phones, internet connectivity, internet speeds, target audience, popularity of the platform and the material prepared for release to the audience were found to influence personal branding. The study recommends that gospel musicians can engage communication professionals to improve their branding, increase their brand equities and fan base. Professional branding can also establish e-commerce options that would enable them to translate their social media fan base into music sales, establish commercial clientele that aligns to their personal brand with a view of growing their financial strength.
