GC-MS Analysis of Volatile Organic Constituents of Traditionally Used Medicinal Plants from the Western Ghats of India: Blumea lanceolaria (Roxb.) Druce., Heliotropium indicum L. and Triumfetta rhomboidea Jacq.

The present study explored essential oil constituents of the medicinal plants used in traditional medicine and growing wild in the Western Ghats region of India, which is one of the 34 global biodiversity hotspots. The hydro distilled essential oils of Blumea lanceolaria (Roxb.) Druce. (Asteraceae), Heliotropium indicum L. (Boraginaceae) and Triumfetta rhomboidea Jacq. (Tiliaceae) were analyzed using gas chromatography equipped with a flame ionization detector (GC-FID) and gas chromatography coupled with mass spectroscopy (GC/MS). Thirty-six, twenty-seven, and fifty constituents were identified from the essential oils of B. lanceolaria, H. indicum, and T. rhomboidea, respectively comprising 97.3% (B. lanceolaria), 98.2% (H. indicum) and 97.6% (T. rhomboidea) of the total oil constituents. The major compounds of B. lanceolaria, H. indicum, and T. rhomboidea were identified as β-pinene (82.3%), methyl salicylate (54.3%), and βcaryophyllene (28.9%), respectively. The essential of B. lanceolaria was found to be rich in monoterpene hydrocarbons (90.4%), while H. indicum and T. rhomboidea oils were rich in phenyl derivative (72.8%) and sesquiterpene hydrocarbons (69.5%) type constituents, respectively. The common compounds viz., terpin-4-ol and eugenol were identified in the essential oils of B. lanceolaria, H. indicum, and T. rhomboidea.
Leiomyosarcoma Tumor Embolism Masquerading as Thrombus in Transit

Patient: Female, 58-year-old Final Diagnosis: Tumor embolism Symptoms: Dyspnea Medication:— Clinical Procedure: Percutaneous embolectomy • surgical embolectomy Specialty: Cardiac surgery • Cardiology • Critical Care Medicine • Oncology Objective: Rare disease Background: Tumor embolism is a rare neoplastic complication that occurs when there is intravenous invasion by a benign or malignant tumor. We present the case of an asymptomatic patient with an incidentally discovered leiomyosarcoma tumor emboli, which was initially misdiagnosed as “thrombus in transit. ” Case Report: The patient was a 58-year-old woman who was incidentally found on echocardiogram to have a large tubular mass within the inferior vena cava and right atrium. Although initially characterized as “thrombus in transit”, this mobile right atrial mass was present without clinical, echocardiographic, or radiographic evidence of pulmonary embolism or increased pulmonary arterial impedance. Given that a thrombus in transit is nearly always associated with submassive or massive pulmonary emboli and their attendant right heart sequelae, these pertinent negative findings led us to seek an alternative diagnosis. After a trial of conservative management with anticoagulation and attempted removal of the mass with the AngioVac system, the patient ultimately underwent median sternotomy and surgical embolectomy on cardiopulmonary bypass to remove the mass, which was later identified on pathology as a leiomyosarcoma. Conclusions: With rare exceptions, “thrombus in transit” is accompanied by large pulmonary emboli and the presence of increased pulmonary artery pressure and right heart strain. The absence of clinical, echocardiographic, or radio-graphic evidence of these hemodynamic sequelae should raise suspicion for an alternative diagnosis. Tumor embolism should be considered in the differential diagnosis of any patient with a history of malignancy who presents with evidence of intracardiac mass or embolism.
Clinical Significance of Campylobacter and Related Species Other Than Campylobacter jejuni and Campylobacter coli

This chapter describes the microbiology, epidemiology, and clinical features of infection with Campylobacter species other than C. jejuni subsp. jejuni and C. coli that are associated with human disease. The major habitat of C. fetus is the intestine, and it is commonly isolated from healthy sheep and cattle. C. fetus infections are often prolonged and result in relapse, but most patients will recover with appropriate antibiotic treatment and medical procedures. C. upsaliensis is a recognized human pathogen in both healthy and immunocompromised patients. C. hyointestinalis was identified and suggested as a possible cause of proliferative enteritis in pigs. Six Campylobacter species have an essential growth requirement for hydrogen or formate. A membrane-bound hemolytic phospholipase was detected and characterized in clinical strains of C. concisus isolated from Australian children with gastroenteritis. The presence of this potential virulence factor suggests C. concisus is an opportunistic pathogen. Two recent reviews summarize clinical presentation, pathogenicity, and other aspects of Arcobacter infection. The chapter also describes other Helicobacter and Campylobacter species. The clinical relevance of the newly recognized Campylobacter species has yet to be determined. PCR assays for the simultaneous detection and differentiation of the genera and individual species of Campylobacter, Helicobacter, and Arcobacter may make this task easier. Appreciation and application of an efficient protocol is essential for the isolation of non-jejuni, non-coli Campylobacter species for surveillance, epidemiological, and other studies.

Effects of Acoustic Excitation on the Combustion Instability of Hydrogen–Methane Lean Premixed Swirling Flames

Lean premixed flames are useful for low nitrogen oxide (NOx) emissions but more prone to induce combustion instability in gas turbines. Combustion instability of a lean premixed swirling flame (LPSF) with hydrogen–methane was investigated experimentally. The effects of hydrogen addition on combustion instability with equivalence ratios 0.75–1 were investigated with acoustic frequencies (90–240 Hz) and acoustic amplitudes (the ratio of velocity fluctuation to an average velocity of 0–0.5), respectively, which are characterized by the gain and phase of the flame describing function (FDF). The evolution of vortex and the flame morphologies were observed by the particle image velocimetry (PIV), intensified charge-coupled device (ICCD), photomultiplier tube (PMT), and Cassegrain optical systems. The global and local heat release fluctuations of the LPSF were shown by CH*/OH* chemiluminescence and temperature measurements. Results show that the FDF features maximum and minimum gain values in the acoustic frequency range of 90–240 Hz and reaches local maximum peaks at 110 and 180 Hz and local minimum peaks at 160 Hz. It can also be observed that varying velocity amplitudes (0–0.5) have greater effects on the gain and phase of FDF than changing equivalence ratios (0.75–1) for lean swirling flames. Higher velocity amplitudes more effectively intensified the compression of the flame length, which enhanced the mixing of the high-burning gas and the unburned gas, and then heat release fluctuations increased. However, it is more interesting that the effects of hydrogen addition on the combustion instability of the LPSF show a completely opposite phenomenon due to acoustic frequency under all experimental conditions. The FDFs were compared at typical frequencies of 140 and 180 Hz, and it was found that combustion instability enhanced with increasing hydrogen content at 140 Hz while weakened at 180 Hz. The flow field of PIV images shows that it is related to the location and development of vortices in the flame with varying acoustic frequencies. The intensity of OH*/CH* chemiluminescence, local temperature, and heat release rate show the same changing trend with the flame morphology for two acoustic parameters with the increasing hydrogen content in the LPSF. This directly affects the compression and curvature of the LPSF and thereby changes the mixture and temperature of the combustible gas, which influence the heat release fluctuation of the LPSF.
Predictive Modeling of Marine Mammal Density from Existing Survey Data and Model Validation Using Upcoming Surveys

Abstract : To meet the information needs of the Navy and other users of the marine environment, cetacean density is modeled as a continuous function of oceanographic variables for 12 species in the California Current Ecosystem (CCE) and 15 species in the Eastern Tropical Pacific (ETP) based on line-transect surveys conducted from 1986 to 2003. Models are validated with new survey data from 2005 and 2006. To evaluate effects on models, different modeling approaches, different sample scales, different interpolation, methods, and different sources of habitat information were exploded. The effect of seasonal changes in cetacean density was also investigated. Final models for all years were incorporated into a software system that will allow users to estimate density for all cetaceans in any user-defined area within the CCE and ETP study areas. Stratified density estimates are also included in the software system for those species for which density modeling was not possible. Our models and associated software will greatly improve the ability to estimate the density of cetaceans within these study areas.
Short-term electricity price forecast based on long short-term memory neural network

Effective short-term electricity price forecasting is of great significance to reduce bidding risk and obtain stable income. In order to predict the timing price, this paper proposes a short-term electricity price forecasting model based on Long Short-Term Memory (LSTM) neural network. The model uses pauta criterion and Lagrange interpolation polynomial to process the historical data of electricity price, normalize the obtained data and input it into the LSTM network layer, using the Mean Squared Error as the loss function to measure the model forecasting. The effect is based on the loss function, and the weight coefficient of the LSTM neural network is updated by the Adam algorithm. Finally, the timing of the LSTM neural network is predicted. Using the real-time data of the California power market and the real-time data of the US PJM power market, it is proved that the accuracy of this method is higher than that of BP neural network, Cart regression tree and polynomial regression.

Variability in aggressiveness of Quambalaria pitereka isolates

Quambalaria shoot blight, caused by the fungal pathogen Quambalaria pitereka, is a serious disease of eucalypt plantations in Australia. The aggressiveness of four Q. pitereka isolates was compared on a range of host genera, species, provenances and clones. Isolates differed substantially in their aggressiveness, with two consistently showing higher levels of aggressiveness based on incidence and severity of disease and lesion size. Isolates derived from Corymbia citriodora subsp. variegata (Ccv) and C. torelliana were shown to have a relatively restricted host range, with lesions but no sporulation found on Eucalyptus species, Angophora species other than A. costata and Corymbia species other than Ccv, the host of origin. The level of aggressiveness toward the different provenances of spotted gum and C. torelliana varied between isolates and there was evidence of some isolate × host interaction within provenances of Ccv. The two methods of inoculation used in this study, spray and spot inoculation, gave similar results. However, the fact that the spot inoculation method was labour-intensive was a disadvantage limiting the numbers of isolates and hosts that can be tested.
South African Petrol Price and Consumption Cointegration Analysis

: In this study, the relationship between the quarterly data of consumption and price of petrol from 2005-2017 is considered. The two series are found to be integrated of the same order I(1) based on the ADF test. Though both variables do not have long-run equilibrium relationship based on Engle-Granger and Johansen tests but there exists a unidirectional causality from consumption to the retail price of petrol. The VAR Models estimated are found to be significant and stable and without any defects (i.e., no heteroskedasticity, no serial correlation and residuals of these VAR Models are found to be normally distributed).
Improving Prognosis of Surrogate Assay for Breast Cancer Patients by Absolute Quantitation of Ki67 Protein Levels Using Quantitative Dot Blot (QDB) Method

Background Immunohistochemistry (IHC)-based surrogate assay is the prevailing method in daily clinical practice to determine the necessity of chemotherapy for Luminal-like breast cancer patients worldwide. It relies on Ki67 scores to separate Luminal A-like from Luminal B-like breast cancer subtypes. Yet, IHC-based Ki67 assessment is known to be plagued with subjectivity and inconsistency to undermine the performance of the surrogate assay. A novel method needs to be explored to improve the clinical utility of Ki67 in daily clinical practice. Materials and Methods The Ki67 protein levels in a cohort of 253 specimens were assessed with IHC and quantitative dot blot (QDB) methods, respectively, and used to assign these specimens into Luminal A-like and Luminal B-like subtypes accordingly. Their performances were compared with the Kaplan–Meier, univariate, and multivariate survival analyses of the overall survival (OS) of Luminal-like patients. Results The surrogate assay based on absolutely quantitated Ki67 levels (cutoff at 2.31 nmol/g) subtyped the Luminal-like patients more effectively than that based on Ki67 scores (cutoff at 14%) (Log rank test, p = 0.00052 vs. p = 0.031). It is also correlated better with OS in multivariate survival analysis [hazard ratio (HR) at 6.89 (95% CI: 2.66–17.84, p = 0.0001) vs. 2.14 (95% CI: 0.89–5.11, p = 0.087)]. Conclusions Our study showed that the performance of the surrogate assay may be improved significantly by measuring Ki67 levels absolutely, quantitatively, and objectively using the QDB method.
1 New class of graphene-based devices for the next generation of nonvolatile memories

Graphene is a one-atom thick layer of carbon atoms arranged in a hexagonal lattice. Graphene potentialities are attracting a lot of researchers to probe opportunities in a number of directions in the “more Moore” or “beyond CMOS” optics in order to identify the new future technologies [1–3]. Another promising utilization of graphene and related nanomaterials is to fabricate nonvolatile memories (NVM) exploiting their “memresistive” behavior storing a value of electrical resistance in a permanent way. This happens when a current passing through the materials changes the level of resistance. Therefore, resistive memory exploits the change in the resistance of a material under the effect of an electric field as an information write/erase principle for nonvolatile data storage. The reading of resistance states is nondestructive, and the memory devices can be operated without transistors in every cell [4, 5], as for flashtype memories [6–10] (see Section 1.2.2), thus achieving a classic cross-bar structure. This kind of memories is called resistive random-access memory (RRAM or ReRAM) and is only one of the possible types of nonvolatile ways to store information in a permanent way. One of the most important advantages of these new classes of 2D materials is that these materials can be implemented in flexible electronics [11–15], in the form of one-thick atom layers as for graphene or in the form of layers of flakes of graphene oxide (GO) or reduced GO (R-GO), thereby reducing the final cost of the final device exploiting roll-to-roll fabrication [16]. Another great advantage of ReRAMs is their potential to implement them by exploiting only two terminals to work (two contacts and not three as a common transistor, which has drain, source and gate, e.g., flash-type memories), which could dramatically reduce the circuitry and allow to implement easily in 3D architectures by using the roll-to-roll fabrication technique. Potentially, this is applied in various fields such as health monitoring [17–21], intelligent packaging [22, 23], cards, labels, badges, value paper and medical disposables. Another potential field is the radiofrequency identification (RFID). This is a technology to electronically record the presence of an object using radio signals. Indeed, an innovative alternative pathway to reduce RFID costs and integrate a memory chip to store data is to eliminate the silicon substrate completely, and produce RFID and memory on the same flexible plastic substrate as the antenna [24–26].
Addressing Childhood Hunger during the Summer Months: Using Gleaned Produce for Snacks and Interactive Nutrition Education on Food Systems and Healthy Eating

ABSTRACT In the United States, 6.5 million children experience food insecurity. The purpose of this project was to evaluate the Building Blocks for Healthy Kids summer nutrition education program for low-income children. Twenty-six children ages 6–11 years participated in the six-lesson program that included snacks incorporating gleaned produce. Plate waste data indicated 55-80% of the served snack was consumed. Knowledge related to nutrition and food systems increased between pre- and post-intervention (p < .0001). At post-intervention, children reported practicing more mindful and sustainable eating practices. Overall, the program increased knowledge and improved food-related behaviors in low-income children.
The Effect of Concentration of Personal Care Pollutant in Domestic Wastewater on the Efficiency Removal of COD and Ammonium in Batch Reactor

One of the dominant compound in a personal care product is sodium lauryl sulfate (SLS). So in this study, SLS is used as a pollutant that might influence the anaerobic digestion treatment. The effect of SLS on the efficient removal of ammonium (NH4+) and COD can be investigated with anaerobic batch reactors. In these reactors, house septic tank sediments were contacted with artificial wastewater with ammonium concentration 30 mg NH4+−N/L and 300 mg/L COD concentration. Reactors are operated for 15 days with variations of SLS concentration 0, 5, 10, 50, 100 mg/L. The best COD removal efficiency and the rate is in the 5 mg SLS/L with the efficiency value of 99,6% and a reduced rate of 19,67 mg/L. The efficiency and rate of COD removal continue to decrease with increasing SLS concentrations. Meanwhile, the best ammonium (NH4+−N) removal efficiency and the rate is in the 0 mg SLS/L with an efficiency value of 73,32% and a reduced rate of 1,30 mg/L. The magnitude of the efficiency and removal rate of ammonium also decreases with increasing SLS concentration. Temperature and pH values for all reactors are in the range of 26-28°C. The pH values in the five reactors were relatively the same both without and with the addition of SLS concentrations.
UNSCHEDULED RETURN VISITS TO THE EMERGENCY DEPARTMENT: INCIDENCE, REASONS, POSSIBLE SOLUTIONS

The rate of attendance at the Emergency Department (ED) is annually increasing worldwide. Return visits constitute 5% of all visits to the ED. The aim of this review is to determine the incidence and reasons of the readmissions to the ED as well as to provide possible solutions in order to avoid unscheduled return visits. Therefore, literature review was conducted using the databases of Medline, PubMed, Cinahl and Cochrane (from inception to September, 2019). Various keywords were used in the advanced search: return visits, unscheduled returns, revisits, unplanned return visits, readmission. Approximately 40 articles that met the inclusion criteria were selected for this paper. Various time frames – 48 hours, 72 hours, 7 days, 30 days, 180 days ‒ were applied for the evaluation of return visits. Unplanned return visits (URV) are more likely to happen in elderly patients, in those who have the underlying disease and in younger children aged less than six years. The main causes of the return visits are the factors related to the patients or to the physicians (disease progression, medical errors, delayed diagnosis, or misdiagnosis). The highest return rates according to the medical conditions have been recorded for the abdominal pain, urinary tract infections, and migraine. Hospitalized patients constitute up to 40% of returning patient cases. There is no consensus on the term or time frame employed to classify the return visits to the ED. Most commonly used readmission time frames reveal the evidence regarding the factors related to patients, illnesses, and staff. The future researches should focus on patient education, clinicians and healthcare providers in order to facilitate the creation of predictive models for reduction of unplanned readmissions. These proceedings will significantly reduce the expenses, both personnel resources and institutional costs.
