Effective Home Automation Using Android and Embedded System

The home automation needs to make use of latest and advance technology to makes it flexible, reliable and cost effective. Home automation involves introducing a degree of computerized or automatic control to certain electrical and electronics system in a building. The popularity of home automation has been increasing greatly in recent years due to much higher affordability and simplicity through smartphone and tablet connectivity. Most research aims to design and develop home automation system which is wireless and can be controlled via a multiple way to give more accessibility and control over a wide range of the systems. The main purpose is to develop and design an automation system which is accessible remotely to monitor and controlling it in a user-friendly way. Wireless communication in home automation systems is focused on low-power wireless communication modules. This paper proposes a cost-effective home automation system which is contains a combination of Android smart phone or tablet or a laptop and embedded system which include Arduino Due Board, Ethernet Shield module and Relay circuit. Also, most researches use an open source or a payed software to be used under Android media of the smart phones, but here the required interface Android pages are designed and implemented by researcher which reduce the cost of the proposed system effectively.
Measuring ecological preference for growth of the most influential weeds in weed community structure associated with agronomic and horticultural crops in Nile Delta, Egypt

The studying of the performance of weeds and weed assemblages associated with different crops through phytosociological researches derives its importance mainly from weeds adverse impact on crop productivity. Hopefully, the current study is bene cial for developing a sustainable long term weed control and soil management strategy. The objective of the present work is to measure three ecological preferences: crop diversi cation, soil type and crop seasonality. A sample area was selected comprising farmland of Nile Delta and its adjoining east and west territories, Egypt. Sixty-four sites in 12 governorates comprising 30 agroecosystems were monitored. 150 species were designated as most in uential weed-species out of 555 species recorded. Ecological preference for species for crop seasonality was evident through the results of Agglomerative hierarchical clustering (AHC). Three weed communities or weed assemblages’ groups (WAG) were identi ed. Their diversity evaluated and their linear correlation strength was determined. The delity measurements showed that 60-species have delity to WAG A; 46 to WAG B; 44 to WAG C. Measuring the ecological preference of species for crop diversi cation and soil type indicated that the growth activity of 36-species was more affected by crop diversi cation; 63-species preferential for growth in ne grained soil (FGS) and 87-species in coarse grained soil (CGS). By employing Redundancy analysis (RDA) with variation partitioning (VP), the variability in species frequency in WAG that can be explained by ecological preference of species for the three ecological preferences was determined and variation was partialized out to estimate their partial, linear effect. In fact, weed control is a recalcitrant issue and the current study revealed that a portion of the solution is in a successful crop diversi cation plan. The successful selection for a competitive crop that can be taken seriously as an adequate weed controlling mechanism in a crop rotation technique will
On the effect of thermophoretic force, gravitational force, and particle–particle interactions in field-flow fractionation

ABSTRACT The theoretical calculations confirmed that the gravitational force cannot be neglected in all field-flow fractionation techniques separating nanometer-sized colloidal particles whenever particle diameter is approximately 200 nm and larger. Particle–particle repulsive interactions, mostly electrostatic repulsions, influence substantially concentration distribution established by any effective field acting across the fractionation channel, as confirmed explicitly for thermophoretic force generated by temperature gradient in microthermal field-flow fractionation. The ionic strength of the carrier liquid causes the screening of the electrostatic double layer around the dispersed particles and thus influences the retention. The attractive particle–particle forces occur when the zeta potential of the particles approaches to 0 mV, the electrostatic repulsions are screened, and the aggregation of the particles is observed. The pH influences differently the size and zeta potential of the plain polystyrene latex particles and of the particles modified on the surface by the groups –COOH and –NH2. The role of a detergent in carrier liquid is non-negligible, as demonstrated by its presence or absence in carrier liquid.
A novel E-Subgroup Pentatricopeptide Repeat Protein DEK55 is Responsible for RNA Editing at 15 Sites and Splicing of nad1 and nad4 in Maize

Background Pentatricopeptide repeat (PPR) proteins is a large protein family, which participate in RNA processing in organelles and plant growth. Previous reports have generally considered E-subgroup PPR proteins as an editing factors for RNA editing. However, the underlying mechanisms and effects of E-subgroup PPR proteins remain to be investigated.Results In this study, we recognized and identified a new maize kernel mutant with arrested embryo and endosperm development, defective kernel 55 (dek55). Genetic and molecular evidences suggest that the defective kernels resulted from a mononucleotide alteration (C to T) at + 449 in the open reading frame (ORF) of Zm00001d014471 (hereafter referred to as DEK55). DEK55 encodes an E-subgroup PPR protein within mitochondria. Molecular analyses suggest that DEK55 plays crucial roles in RNA editing at multiple sites of ribosomal protein S13, ATP synthase subunit1, NADH dehydrogenase-6 (nad6), and nad9 transcripts as well as in splicing of nad1 and nad4. The mutation of DEK55 lead to the dysfunction of mitochondrial complex I.Conclusions Our results demonstrate that the DEK55 mutation is responsible for the dek55 mutant phenotypes, as it affects mitochondrial function that is essential for maize kernel development. This study also provides novel insight into the molecular function of E-subgroup PPR proteins in plant organellar RNA metabolism.
Distribution kinetics modeling of nucleation, growth, and aggregation processes : Novel reactor engineering for the new millennium

Certain emerging fields of nanotechnology depend on self-assembly processes that lead to molecular structures which are organized and ordered or disorganized and disordered. Many such processes can be understood as combinations of nucleation, reversible growth, and reversible aggregation. We develop a descriptive theoretical framework through population balances for the cluster mass distribution and show the formulation of its mass moments. Calculations for relaxation to equilibrium show the effects of aggregation, deaggregation, dissolution, cluster growth by monomer addition, and nucleation, as either single processes or various combinations. Competition among the processes yields a variety of different behaviors that have been observed in nature and in the laboratory. Problems that can hinder self-organization processes include coarsening (Ostwald ripening) and glasslike phase transition (noncrystalline solidification). Both of these and other processes can be described by the kinetics of cluster distributions and the dynamics of their moments.
KINETICS AND MODELING OF ODOR OXIDATION USING CHLORINE DIOXIDE FOR EMISSION CONTROL UTILIZING WET SCRUBBERS

The promulgation of “Odor Control Rules”, increasing public concerns, and EPA air regulations in non-attainment zones, necessitates the remediation of a wide range of volatile organic compounds (VOCs) generated in the rendering industry. Currently, wet scrubbers using oxidizing chemicals, such as ClO2 are utilized to treat VOCs. However, little information is available on the kinetics of ClO2 reaction with rendering air pollutants, limiting wet scrubber design and optimization. Kinetic analysis indicated that ClO2 does not react with hexanal and 2-methylbutanal (aldehydes constitute a major VOC fraction) regardless of pH and temperature, and imply aldehyde removal is primarily via mass transfer. Contrary to the aldehydes, ethanethiol (a model compound for methanethiol) and dimethyl disulfide (DMDS) rapidly reacted with ClO2. The overall reaction was found to be second and third order for ethanethiol and DMDS respectively. Moreover, an increase in pH from 3.6 to 5.05 exponentially increased the reaction rate of ethanethiol (e.g., k2 = 25 to 4200 L/mol/s from pH 3.6 to 5.1) and significantly increased the reaction rate of dimethyl disulfide if increased to pH 9 (k3 = 1.4 x 106 L2/mol2/s). Thus, a small increase in pH could significantly improve wet scrubber operations for removal of odor causing compounds. However, an increase in pH did not improve aldehyde removal. The results explain why aldehyde removal efficiencies are much lower than methanethiol and DMDS in wet scrubbers using ClO2. Wet scrubber models without chemical reaction predicted aldehyde removal within 17-32% of removal efficiencies in an industrial scale scrubber. Incorporating oxidation kinetics into a wet scrubber model predicted increasing removal efficiency with increasing pH (i.e., reaction rate) but did not adequately predict results in an industrial scale scrubber.
Strategies to Handle Increased Demand in the COVID-19 Crisis a Corona Telephone Hotline and a Web-based Self-triage System

BackgroundIn emergencies, such as the COVID-19 pandemic, there is an increased need for contact withemergency medical services (EMS), and call volume might surpass capacity. Thus, the Copenhagen EMS in Denmark implemented a separate coronavirus hotline followed by a web-based self-triage system to reduce nonemergency call volume. The aim of this paper is to present the two measures implemented to handle the increased call volume to the Copenhagen EMSfromthose with mild or no relevant COVID-19 symptoms.MethodsThis is a cross sectional observational study monitoring call volume in the first month of the COVID-19 pandemic in accumulated callnumbers, compared to the equivalent numbers during one month from the year before (2019). A coronavirus hotline and web-based self-triage system arepresented in absolute numbers of users.ResultsIn the first month of the COVID-19 pandemic in Copenhagen, emergency medical dispatch centers were extensively overloaded with more than 10.800 calls, resulting in significantly prolonged queue time (mean time in minutes:12:02; CI: 11:55-12:09)) compared to 2019 (mean time in minutes02:23; CI: 02:22-02:25) and thereby limiting access to emergency assistance and triage for citizens. The introduction of the coronavirus hotline showed reduced call volume and queue time to the EMS. The web-based self-triage system was used more than 107.000 times. However, no correlation between call volume and the use of a web-based self-triage systemwas observed.ConclusionsCreating a coronavirus hotlinestaffed by healthcare personnelseemed to have an impact on call volume and potentially relieved the strain in resources, while the web-based self-triage system was widely used and could be further developed to reach itsfull potential. Other EMS organizations can implement these measures to enhance capacity in a future epidemic.
NUMERICAL SIMULATION OF SOIL LIQUEFACTION DURING THE 20 MAY 2012 M6.1 EMILIA EARTHQUAKE IN NORTHERN ITALY: THE CASE STUDY OF PIEVE DI CENTO

On May 20, 2012, a seismic event of moment magnitude M W = 6.1 hit and caused severe damage on a large area in the river Po Valley, located in the northern Italy. This earthquake was characterized by extensive occurrence of soil liquefaction and basin effects lying over deep deposits. Within the scope of the European research project titled LIQUEFACT, a reference site located in the countryside near the hamlet of Pieve di Cento (at the boundary of the province of Bologna towards Ferrara) was selected as a trial field in order to assess the effectiveness of several mitigation measures against liquefaction. As a first step of the task, this paper presents the geotechnical model of the site based on in-situ investigations and pre-existing geological studies, which allowed to locate the bedrock depth. As a second step, representative input motions for the LIQUEFACT project were selected aiming at simulating the 20.V. 2012 seismic event as well as three possible future scenarios with an increasing level of seismic intensity. Finally, preliminary dynamic analyses are presented, that reproduce the observed liquefaction triggering after the 2012 main event and predict the seismic soil response at the test site.
Quercetin Attenuates the Production of Pro-Inflammatory Cytokines in H292 Human Lung Epithelial Cells Infected with Pseudomonas aeruginosa by Modulating ExoS Production

The type three secretion system (T3SS) is a major virulence system of Pseudomonas aeruginosa (P. aeruginosa). The effector protein Exotoxin S (ExoS) produced by P. aeruginosa is secreted into the host cells via the T3SS. For the purpose of an experiment on inhibitors with regard to ExoS secretion, we developed a sandwich-type enzyme-linked immunosorbent assay (ELISA) system. Quercetin was selected because it has a prominent ExoS inhibition effect and also is known to have anti-inflammatory and antioxidant effects on mammalian cells. In this study, we investigated the effects of quercetin on the expression and secretion of ExoS using ELISA and Western blot analysis methods. The results showed that the secretion of ExoS was significantly decreased by 10 and 20 μM of quercetin. Also, popB, popD, pscF, and pcrV which are composed of the T3SS needle, are reduced by quercetin at the mRNA level. We also confirmed the inhibitory effect of quercetin on cytokines (IL-6, IL-1β, and IL-18) in P. aeruginosa-infected H292 cells by real-time polymerase chain reaction (PCR) and ELISA. Collectively, quercetin inhibits the secretion of ExoS by reducing both ExoS production and the expression of the needle protein of T3SS. Furthermore, these results suggest that quercetin has the potential to be used as an anti-toxic treatment for the inflammatory disease caused by P. aeruginosa infection.
Liquid Based Cytology for the Detection of Cervical Intraepithelial Lesions among Women in Jimma Town, Ethiopia

Background: Cervical cancer is the second leading type of female cancer in Ethiopia. Screening is primarily conducted using visual inspection with 5% acetic acid (VIA). Liquid-based cytology (LBC) has not yet been used in Ethiopia.Method: Women aged 21-65 years were tested using LBC and VIA for the detection of cervical dysplasia. Logistic regression analysis was conducted to identify associated factors. Cohen’s K test was conducted to test agreement between LBC and VIA. Results: Forty-two percent (n=188) of 448 participants were 31 to 40 years of age and only two participants were above 60. Of the 448 participants, 419 (93.5%) were tested with LBC, 294 (65.6%) VIA and 272 (60.7%) with both LBC and VIA. Among women screened using LBC, 305(72.8%) were negative for intraepithelial lesion or malignancy (NILM), 97 (23.2%) had low grade squamous intraepithelial lesion (LSIL) and 17 (4.1%) high grade squamous intraepithelial lesion (HSIL). Presence of cervical lesions was generally lower in younger and older aged women. Majority, 39(40%) with LSIL and 10 (59%) of women with HSIL were 41-50 years old. Women aged 51-60 years were more likely to have abnormal intraepithelial lesions compared to women aged 21-30 (AOR= 20.9,95%CI=[7.2-60.9], p=0.00). Out of 47 (10.8%) HIV-patients,14(32.56%) had intraepithelial lesion of which 10(23.3%) and 4(9.3%) had LSIL and HSIL, respectively. Among women screened with VIA, 18 (6.1%) were positive. Among the 272 (60.7%) women screened using both LBC and VIA, 6 (2.2%) were positive on both LBC and VIA. The level of agreement between the two tests was weak and statistically significant (kappa value=0.155, p=0.006). Conclusion: LBC detected high cervical squamous intra-epithelial lesions in our setting. VIA was a less reliable predictor of cervical squamous intra-epithelial lesions than LBC. Evaluating diagnostic accuracy of both LBC and VIA against histological endpoint should be completed before adopting either screening modalities.
Diglycidylether of iso-eugenol: a suitable lignin-derived synthon for epoxy thermoset applications

A novel lignin-based synthon, diglycidylether of iso-eugenol (DGE-isoEu) is used as a prepolymer for the preparation of thermosetting resins. DGE-isoEu is synthesized in a two-step procedure with a satisfactory yield from bio-based iso-eugenol (isoEu, 2-methoxy-4-(1-propenyl)phenol) catalytically fragmented from lignin in an organosolv process. DGE-isoEu was fully characterized by NMR, MS and FTIR. Curing of the DGE-isoEu monomer has then been investigated in the presence of several carboxylic acid derivatives hardeners. The thermal and mechanical properties of each material were recorded showing, in particular, a high Tg and instantaneous modulus values in the range of 78–120 °C and 4.6–5.5 GPa, respectively. The lignin derived new materials give very attractive thermo-mechanical properties comparable to that of common BPA-containing epoxy resins.
edgar: An R Package for the U.S. SEC EDGAR Retrieval and Parsing of Corporate Filings

This paper introduces the R package "edgar" to download and analyze the Securities and Exchange Commission's (SEC) mandatory public disclosures in the United States. Corporations in the U.S. submit their periodic reports, registration statements, and financial reports electronically to the SEC. The SEC makes these reports publicly accessible to everyone through the Electronic Data Gathering, Analysis, and Retrieval System (EDGAR). As financial reporting is one of the most crucial aspects of the financial system, efficient retrieval of EDGAR filings becomes imperative for analysts and researchers. We summarize the implementation of the "edgar" package that facilitates downloading, parsing, searching, and sentiment analysis of corporate reports.
Aspartate transaminase/alanine transaminase ratio as a significant prognostic factor in patients with sepsis: a retrospective analysis

Background: The study was performed to investigate the relationship between aspartate transaminase/alanine transaminase ratio (DRR) and long-term mortality among patients diagnosed with sepsis or septic shock. Methods: We conducted a retrospective study among adult septic patients who were admitted to surgical intensive care unit (ICU) of the Chinese People's Liberation Army (PLA) General Hospital from January 2014 to December 2018. Baseline characteristics were compared between survivors and non-survivors. We applied univariate as well as multivariate Cox regression analyses to evaluate DRR in relation to 180-day mortality. The potential prognostic value of DRR in predicting mortality rate was assessed by receiver operating curve (ROC) analysis. Besides, we conducted subgroup analysis by stratifying patients via optimal DRR cut-off value. Results: We included a total number of 183 patients in the current study, 44 (24%) patients died within 180-day hospitalization. Univariate and multivariate Cox analysis revealed that DRR was an independent predictor of 180-day mortality (hazard ratio [HR] 1.421, 95% confidence interval [CI] 1.073-1.883, P = 0.014). The predicting accuracy of 180-day mortality for DRR was presented as ROC with an area under the curve (AUC) of 0.708 (95% CI 0.629–0.786, P < 0.001). As we stratified all enrolled patients into two groups by using the optimal cut-off value of 1.29, we observed a significantly higher mortality in patients with relatively high DRR. Conclusions: An elevated DRR was associated with higher 180-day mortality among septic patients, and DRR might be an optimal marker for predicting the long-term mortality of sepsis. More prospective and randomized trials are needed to confirm the prognostic value of DRR.
Adjuvant Therapy Using Lenvatinib Prevents Recurrence of High-Risk Patients with Hepatitis B Virus-Related Hepatocellular Carcinoma Following Liver Transplantation: A Retrospective Case Control Study

Background: Although liver transplantation (LT) is one of the most effective treatments for the patients with hepatocellular carcinoma (HCC), the high-risk patients suffer from a high ratio of tumor recurrence after LT. So this study was designed to evaluate the role of adjuvant lenvatinib in preventing recurrence of high-risk LT recipients with HBV-related HCC.Methods: We retrospectively analyzed 23 high-risk patients consisting of lenvatinib group (n = 14) and control group (n = 9) with HBV-related HCC who underwent LT in our center. Disease-free survival (DFS) and HCC recurrence of the two groups were compared. The adverse events (AEs) and drug tolerance of lenvatinib were evaluated.Results: The median DFS in lenvatinib group was 291 (95%CI 204–516) days, significantly longer than 182 (95%CI 56–537) days in control group (P = 0.04). Three patients in lenvatinib group (21.4%) and 5 patients in control group (55.6%) had short-term HCC recurrence (P = 0.11). All patients in lenvatinib group could tolerate oral lenvatinib for at least 3 cycles except 6 cases (42.9%) of dose reduction and 1 case of interruption (14.3%). Thirteen patients (92.9%) taking lenvatinib experienced AEs. The most common AEs were hypertension (64.3%) and proteinuria (42.9%), and the most serious AEs were CTCAE Grade 3 for 4 cases (28.5%). Additionally, no influence of lenvatinib on the dosage and blood concentration of FK506 was observed.Conclusion: Adjuvant lenvatinib had a potential benefit on prolonging the DFS and reducing the recurrence of high-risk HBV-related HCC patients following liver transplantation with an acceptable drug safety and patient tolerance.
From a Three-Phase Model to a Continuous Description of Molecular Mobility in Semicrystalline Poly(hydroxybutyrate-co-hydroxyvalerate)

In most cases, a three-phase model consisting of crystalline domains surrounded by rigid amorphous areas dispersed in the mobile amorphous phase is required and eventually sufficient to accurately describe the microstructure of semicrystalline polymers. This work shows that the microstructure developed by poly(hydroxybutyrate-co-hydroxyvalerate) by cold crystallization is better described by a complex two-phase model in which the boundaries of the crystalline domains and the surrounding amorphous environment form a “continuum of mobility”. This concept can be extended to a wide range of semicrystalline polymers. When the crystalline and the amorphous phases are strongly coupled, the rigid and mobile amorphous fractions are hardly fractionated, and the whole noncrystalline phase should be rather depicted as continuum with a broad distribution of the relaxation times associated with the glass transition. Such a depiction of the amorphous phase allows taking into account any modification of the mobility land.
News-Based Links and Cross-firm Return Predictability

Applying a “co-coverage” concept to the Dow Jones Newswire articles, we propose to identify each firm’s news-based links (NBLs) and thereby construct a newsworthiness economic grouping scheme. The advantage of NBLs is to capture the up-to-date relative importance of different economic links between a base firm and its peers. We show that a base firm's share price responses persistently to the shock transmitted from its industry peers reweighted by the NBLs. Additional empirical tests show that the relative importance of those NBLs is not immediately clear to the investors and therefore is reflected sluggishly in the return shock from NBL peers to the base firms. Taken together, our results suggest that monitoring news co-coverage plays an important role in understanding the cross-firm return predictability documented in the literature.
