Human Pulse Diagnosis for Medical Assessments Using a Wearable Piezoelectret Sensing System

Real‐time and continuous monitoring of physiological signals is essential for mobile health, which is becoming a popular tool for efficient and convenient medical services. Here, an active pulse sensing system that can detect the weak vibration patterns of the human radial artery is constructed with a sandwich‐structure piezoelectret that has high equivalent piezoelectricity. The high precision and stability of the system result in possible medical assessment applications, including the capability to identify common heart problems (such as arrhythmia); the feasibility to conduct pulse palpation measurements similar to well‐trained doctors in Traditional Chinese Medicine; and the possibility to measure and read blood pressure.
ASSESSMENT OF ALLELOPATHIC EFFETS OF COGONGRASS (IMPERATA CYLINDRICA L.) ON WHEAT, ONION AND SOME ASSOCIATED WEEDS

Studying the influence of cogongrass (Imperata cylindrica L.) extract on germination and seedling growth of some weeds and crops indicated that the dicotyledonous weeds such as goosefoot and sowthistle were the most affected by the aqueous extract of cogongrass (rhizome and foliage) than the monocotyledonous crops, wheat and onion, based on IC50 values. Delay in germination was more pronounced in weeds than crops. Dry weight of wheat and onion seedlings were not significantly affected meanwhile the dry weight of goosefoot, fieldbind and sowthistle seedlings were significant, by lower than control. Rhizome extract was generally more effective than foliage extract. Allelochemicals in cogongrass (rhizome and foliage) analyzed by liquid chromatography/mass spectrometry (LC/MS) were identified as phenolic compounds that included 3'-o-methyl-(-)-epicatechin-7-o-sulphate, vanillic, ferulic and coumaric acids in rhizome extract, in addition to (-)epigallocatechin-3,5-digallate, caffeic and gallic in foliage extract. Chlorogenic acid was the principal phenolic compound in both extracts. These results suggest that cogongrass might have an inhibitory effect. Considering that cogongrass is an allelopathic plant might suggest its use as soil additive material for weed control and could also serve as natural herbicide.
Genetic differentiation between and within Northern Native American language groups: an argument for the expansion of the Native American CODIS database

Abstract The National Research Council recommends that genetic differentiation among subgroups of ethnic samples be lower than 3% of the total genetic differentiation within the ethnic sample to be used for estimating reliable random match probabilities for forensic use. Native American samples in the United States’ Combined DNA Index System (CODIS) database represent four language families: Algonquian, Na-Dene, Eskimo-Aleut, and Salishan. However, a minimum of 27 Native American language families exists in the US, not including language isolates. Our goal was to ascertain whether genetic differences are correlated with language groupings and, if so, whether additional language families would provide a more accurate representation of current genetic diversity among tribal populations. The 21 short tandem repeat (STR) loci included in the Globalfiler® PCR Amplification Kit were used to characterize six indigenous language families, including three of the four represented in the CODIS database (i.e. Algonquian, Na-Dene, and Eskimo-Aleut), and two language isolates (Miwok and Seri) using major population genetic diversity metrics such as F statistics and Bayesian clustering analysis of genotype frequencies. Most of the genetic variation (97%) was found to be within language families instead of among them (3%). In contrast, when only the three of the four language families represented in both the CODIS database and the present study were considered, 4% of the genetic variation occurred among the language groups. Bayesian clustering resulted in a maximum posterior probability indicating three genetically distinct groups among the eight language families and isolates: (1) Eskimo, (2) Seri, and (3) all other language groups and isolates, thus confirming genetic subdivision among subgroups of the CODIS Native American database. This genetic structure indicates the need for an increased number of Native American populations based on language affiliation in the CODIS database as well as more robust sample sets for those language families.

Horizontal-Leader Identification in Construction Project Teams in China: How Guanxi Impacts Coworkers’ Perceived Justice and Turnover Intentions

Based on social comparison theory and organizational justice, this research explores how Guanxi with the horizontal leader (HL) influences coworker turnover intention. We used the snowball sampling method to collect survey data from 203 employees in 22 project teams. Overall, Guanxi with the HL had an indirect influence on turnover intention through perceived distributive justice pertaining to HL identification. Additionally, procedural justice had a negative, cross-level moderating effect on the relationship between Guanxi with the HL and perceived distributive justice. However, the individual-level moderating role of interactional justice was not supported. Theoretical and managerial implications of these findings are discussed.
Reduction of Serotonergic Gene Expression in the Midbrain Raphe Nuclei under Positive Fighting Experience

The concept of a major inhibitory role of serotonin in aggressive behavior is widely accepted by investigators. There was ample evidence that a pharmacologically-induced increase in the serotonin activity attenuates agonistic behavior in animals and that the manipulations inhibiting the brain serotonergic system can elicit aggressiveness in male mice and rats. Repeated experience of aggression in daily agonistic interactions has been shown to reduce serotonin activity in brain of victorious male mice. The study aimed to analyze expression of the serotonergic genes Tph2, Sert, Maoa and 5ht1a, as well as Bdnf and Creb genes in the midbrain raphe nuclei of male mice with positive fighting experience in daily encounters and male mice with the same track record of aggression followed by two-week no-fight period. It has been shown that mRNA levels of the serotonergic and Creb genes are reduced in the winners in comparison with male mice without consecutive positive fighting experience of aggression. After the fighting deprivation the Tph2, Sert, Bdnf and Creb genes recover their expression while mRNA levels of Maoa and 5ht1a gene proceed at a significantly higher level as compared with the respective controls. Downregulation of serotonergic genes is indicative of the inhibition of serotonergic activity under repeated experience of aggression. Nevertheless, recovering of Tph2 and Sert gene expression and overexpression of Maoa and 5ht1a genes after no-fight period suggest that changes in brain serotonergic activity are not main cause of the behavioral pathology developing in male mice in this experimental context.

Theoretical Study of N-Methyl-3-Phenyl-3-(4-(Trifluoromethyl) Phenoxy) Propan as a Drug and Its Five Derivatives

Quantum chemical calculation was correlated with geometrical structure and total energy of fluoxetine and its five derivatives. Theoretical vibrational frequencies and geometric parameters (bond lengths and bond angles) have been calculated using ab initio (HF), density functional theory (B3LYP), semi-empirical (AM1, PM3) methods with different basis sets to design the fluoxetine drugs and its derivatives by a Gaussian 09 W program. Theoretical optimized geometric parameters and vibrational frequencies of fluoxetine have been compared with the corresponding five derivatives data. The highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energies have been determined. The theoretical study includes the calculation of the thermodynamic properties of the drugs and its derivatives like zero-point energy, enthalpy, entropy, ionization energy, electron affinity to make a correlation between the gained results. The results of the four methods were not very clear, but an correlation between the dipole moment (potential character), static distribution (an active site character) and HOMO-LUMO energies (energy for electron transfer) shows that the patent 1.5 was important derivatives as a recommended drug relative to fluoxetine drug.

The Evaluation of Substrates and Trichoderma sp. Isolates for Cellulase Production

AbstractAs higher interest was on the lignocellulose-based or second generation bioethanol production, the research was then more focused on the production of cellulase, especially on the domestic enzyme. Trichoderma sp. is considered as one of the most efficient producer of cellulase. This study was conducted to investigate the performance of Trichoderma sp. on a variety of substrates to produce cellulase. Three types of substrate variations and three types of Trichoderma sp. were used in this experiment. The substrate used were wheat bran, rice bran and oil palm empty fruit bunches (EFBs), whereas Trichoderma sp. isolates were encoded as T004, T051 and T063. Production of cellulase was made by solid fermentation for 7 days. The analysis of cellulase activity was done by National Renewable Energy Laboratory (NREL) method for filter paper assay. The results showed that the type of substrate affected the performance of Trichoderma sp. All types of fungus produced cellulase on wheat bran substrate with activity of 0.52 FPU /ml for T004, 0.23 FPU/ml for T051 and 0.27 FPU /ml for T063. With the rice bran substrate and EFBs, only T004 could produce cellulase and the enzyme activity analyzed were 0.08 FPU /ml and 0.008 FPU/ml respectively. Optimation of the buffer addition on enzyme extraction process produces the highest activity 0.85 FPU/mL for T004 with wheat bran substrate. Keywords: cellulase, EFBs, rice bran , Trichoderma sp. , wheat bran
Colorectal Cancer Screening: Have We Addressed Concerns and Needs of the Target Population?

Despite the recognized benefits of colorectal cancer (CRC) screening, uptake is still suboptimal in many countries. In addressing this issue, one important element that has not received sufficient attention is population preference. Our review provides a comprehensive summary of the up-to-date evidence relative to this topic. Four OVID databases were searched: Ovid MEDLINE® ALL, Biological Abstracts, CAB Abstracts, and Global Health. Among the 742 articles generated, 154 full texts were selected for a more thorough evaluation based on predefined inclusion criteria. Finally, 83 studies were included in our review. The general population preferred either colonoscopy as the most accurate test, or fecal occult blood test (FOBT) as the least invasive for CRC screening. The emerging blood test (SEPT9) and capsule colonoscopy (nanopill), with the potential to overcome the pitfalls of the available techniques, were also favored. Gender, age, race, screening experience, education and beliefs, the perceived risk of CRC, insurance, and health status influence one’s test preference. To improve uptake, CRC screening programs should consider offering test alternatives and tailoring the content and delivery of screening information to the public’s preferences. Other logistical measures in terms of the types of bowel preparation, gender of endoscopist, stool collection device, and reward for participants can also be useful.

High-Precision Extrinsic Calibration Method of a Time-of-Flight IMU RGB-Camera With Loop Closure Constraints

Accurate localization is key to realizing an autonomous mobile robot. The fusion of depth data measured by a time-of-flight (TOF) camera with visual-inertial simultaneous localization and mapping (SLAM) can greatly improve depth estimation and mapping. To achieve a robust sensor fusion system, precise calibration of one sensor to another is essential. In this paper, we propose a joint extrinsic calibration method for a TOF- IMU RGB-camera system. Further, we design a pattern that consists of white circles with high reflectivity, and a black background with high absorptivity. Using our calibration method, circular features can be accurately extracted from amplitude images as well as from RGB images. We correct the TOF depth measurement errors, which depend on the pixel location and distance of the pixel away from the object, by establishing an error distribution model with a B-spline function. All sensors are fixed on a platform, and the position of each sensor relative to the other sensors is unchanged, forming loop closure constraints. Based on this prerequisite, we utilize the loop closure constraints between multiple sensors to obtain more accurate extrinsic parameters. By taking the loop closure constraints into account, the stability and robustness of the calibration is increased. The experimental results validate the proposed method and prove its accuracy. Thus, we achieve high precision in multi-sensor extrinsic calibration, which is the necessary foundation of SLAM research.
Quantitative analysis of the distribution and mixing of cellulose nanocrystals in thermoplastic composites using Raman chemical imaging

Cellulose nanofibers hold much promise for enhancing the mechanical properties of composites owing to their uniquely high stiffness and strength. One major issue limiting this performance however is the dispersion and mixing of cellulose nanofibers within thermoplastic resins. A combination of Raman imaging and chemical analysis has been used to quantify the distribution and mixing of cellulose nanocrystals (CNCs) in a polyethylene-matrix composite. Large area spectral imaging provides information about the effect of a compatibilizer – namely poly(ethylene oxide) (PEO) and maleated polyethylene (MAPE) – on the distribution of CNCs in the thermoplastic matrix. High-resolution images enable quantification of the degree of mixing between the CNCs and HDPE. Lower resolution images, but with greater spatial spread, allow quantification of the distribution of the CNCs. It is shown that the CNCs tend to agglomerate, with little increase in distribution even with the use of the compatibilizer. A shift in the position of characteristic Raman bands indicates the formation of hydrogen bonding between the PEO compatibilizer and the CNCs, which in turn is thought to affect the distribution of aggregates of the reinforcing phase.
One-Dimensional Fluorene-Based Co(II) Phosphonate Co(H2O)2PO3C–C12H9·H2O: Structure and Magnetism

A new Co(II) phosphonate, Co(H2O)2PO3C–C12H9·H2O, has been synthesized under hydrothermal conditions. The monoclinic P21/c structure of this organic–inorganic hybrid consists of isolated perovskite-type chains of corner-shared CoO4(H2O)2 octahedra interconnected via phosphonate groups. The unique one-dimensional structure of this phase is closely related to the single-chain magnet (SCM) phosphonate Co(H2L)(H2O), with L = 4-Me-C6H4-CH2N(CPO3H2)2, that contains isolated chains of CoO5N octahedra. Like the latter, this hybrid exhibits 1D antiferromagnetic interactions and the possibility of an effective pseudo spin contribution due to spin canting at low temperature, but, in contrast, is not an SCM. This different magnetic behavior is explained by the different geometry of the octahedral chains and by the possible existence of weak antiferromagnetic interactions between the chains. This opens the route to the investigation of a large series of compounds by tuning the chemical composition and structure of the phosphonic acid used as organic precursor of hybrid materials.
Calcium isotope separation by band chromatography using 18-crown-6-ether resin

ABSTRACT To develop the 48Ca enrichment process, a feasibility study on a band chromatography was made using 9 M HCl solution and crown ether resin synthesized in porous silica beads. Prior to the chromatographic experiments, distribution coefficients, Kd, of Ca2+ and Sr2+ were measured at different concentrations of these ionic species. The frontal boundary of the chromatography was made by a usual manner of the breakthrough mode of calcium feeding, and the rear boundary was made by introducing strontium as a following ion on the basis of the observed Kd values. It was confirmed that the heavy isotope 48Ca was depleted in the rear boundary region, while 48Ca was enriched in the front boundary region. The values of separation coefficient ε (= α – 1) in three chromatographic operations at different temperatures were observed as 2 × 10−3 ~ 3 × 10−3. The separation coefficients observed in the front boundary regions, where 48Ca was enriched, agreed with those observed in the rear boundary regions, where 40Ca was enriched.
An Alternative to Increase Accumulation of Phenolic Compound in Grapevine Callus Cultures: Chemical Mutagen Applications

This research was carried out to investigate the effects of chemical mutagen applications on producing phenolic compounds in calli obtained from leaf petiole explants of the Royal grape variety.Petioles were cultured in B5 medium containing 0.5 mg/L benzyl amino purine and 0.5 mg/L indole acetic acid to obtain callus. Calli obtained during the period following planting were subcultured in the same culture conditions three times at one month intervals. In the fourth subculture, the calli were transferred to nutrient mediums with the same composition containing ethyl methanesulfonate, sodium azide, azacitidine and acridine orange in three different doses, 0.5 mM, 1.0 mM, and 2.0 mM, and cultured in these mediums for 60, 120 and 180 minutes. Then, they were cultured again for four weeks in mutagen-free nutrient mediums with the same content as their previous mediums. At the end of this period, calli were taken from their nutrient medium, and total phenolic compound, total flavanol, total flavonol and anthocyanin analyzes were performed.As a result of the research, it has been determined that all mutagens applied are effective in increasing the production of phenolic compounds depending on the dose and time.
Solid State Fermentation Parameters Effect on Cellulase Production from Empty Fruit Bunch

In this study, agriculture waste palm empty fruit bunch (EFB) was used as carbon/cellulose source in solid state fermentation for cheaper cellulase production. Fermentation operation parameters, such as: solid to liquid ratio, temperature, and pH, were varied to study the effect of those parameters towards crude cellulase activity. Two different fungi organisms, Trichoderma viride and Trichoderma reesei were used as the producers. Extracellular cellulase enzyme was extracted using simple contact method using citrate buffer. Assessment of the extracted cellulase activity by filter paper assay showed that Trichoderma viride is the superior organism capable of producing higher cellulase amount compared to Trichoderma reesei at the same fermentation condition. The optimum cellulase activity of 0.79 FPU/g dry substrate was obtained when solid to liquid ratio used for the fermentation was 1:1, while the optimum fermentation temperature and pH were found to be 30 °C and 5.5, respectively. The result obtained in this research showed the potential of EFB utilization for enzyme production. Copyright © 2018 BCREC Group.
