Annual Bluegrass: Emergence of Viable Seed in Various Putting Green Sites and Soil Removal Depths
Authors: Green Thomas O. , Kravchenko Alexandra , Rogers John N. , Vargas Joseph M.
Published: July 2019

A major concern with many creeping bentgrass (Agrostis stolonifera) putting greens is annual bluegrass (Poa annua) invasion. The study was designed to garner data regarding the depth of soil removal needed to reduce annual bluegrass seedling emergence in a newly renovated putting green. Research was conducted in different seasons (summer and fall) to evaluate seedling emergence across five soil removal depths in four sampling sites. Cores were collected from four golf courses in southeastern Michigan, subdivided into different soil removal depths, potted in sterile soil media, and established in a growth chamber. Results suggest that excavating soil to a depth of 1.0 inch or, more prudently, to a 1.5-inch depth could minimize annual bluegrass competition in a creeping bentgrass putting green. Annual bluegrass emergence was observed to be greatest in the upper soil depths (0.5–1.5 inches) in both seasons, with minimal emergence (<1.1 plant/0.2 ft2) below the 2.0-inch soil removal depth treatment.
Consumer Perception of Skinning Injury in Sweetpotatoes and Implications for Marketability: An Experimental Auction
Authors: Collart Alba J. , Meyers Stephen L. , Ward Jason K.
Published: July 2019

Skinning of sweetpotato (Ipomoea batatas) storage roots is one of the greatest concerns of sweetpotato producers. Although skinning injury is very common, the severity of the injury can vary widely. At an undefined threshold, sweetpotatoes with skinning injury are no longer sold for fresh consumption. The objectives of this study were to examine how skinning injury influences consumers’ willingness-to-pay (WTP) for sweetpotatoes and to identify differences in valuations when the extent of skinning injury is labeled. Image analysis was used to quantify skinning injury and then an incentive-compatible, nonhypothetical laboratory experimental auction was conducted to collect data on consumers’ WTP for five categories of sweetpotatoes: 0% to <1% skinning injury, 1.0% to 3.0%, 3.1% to 5.0%, 5.1% to 7.5%, and 7.6% to 10.0%. On average, consumers were willing to pay the most for sweetpotatoes with 0% to <1% skinning injury (up to $1.51/lb to $1.67/lb) and the least for sweetpotatoes with 7.6% to 10% (up to $0.76/lb to $0.85/lb), yet mean WTP values were nonzero for all skinning levels. Moreover, when the extent of skinning was labeled (relative to when they bid blindly), consumers were willing to pay price premiums for sweetpotatoes with low skinning injury levels (0% to 5%) and discounted sweetpotatoes with the highest skinning injury level (7.6% to 10.0%), suggesting that skinning levels of 7.6% and above may not be acceptable by consumers.
Investigation of acoustic scattering from a pair soundproof spheres under external influence
Authors: Nasibullaeva E.Sh.
Published: July 2019

A mathematical model extension is presented and numerical studies were made for the problem of acoustic scattering from two soundproof spheres (the case of hard spheres) with an arbitrary acoustic impedance under the action a spherical wave from a monopole radiation source arbitrarily located in space. The case of two spheres is of practical interest, since, on the one hand, the scattered fields from the spheres interact with each other, and on the other hand, the interaction is simple enough for it to be studied in detail. When solving the Helmholtz equations, a numerical technique based on the fast multipole method is used, which allows to achieve high accuracy of the results obtained with minimal computer time. The testing of the algorithm was carried out on the basis of the known data (from the literature) of the response on the surface of one of the spheres in the case when the axis connecting the monopole radiation source and the center of the first sphere is perpendicular to the axis connecting the centers of the two spheres. The pressure distribution around the spheres is investigated for different values of the distance between the centers of the spheres and the arbitrary location of the monopole radiation source in space. It is shown that with certain parameters of the system, the presence of a second sphere can lead to the appearance of an increase or decrease zone of pressure. The obtained results will further allow generalizations of the mathematical model to the cases of acoustic scattering from a pair of sound-permeable spheres (cases of gas bubbles or liquid droplets) and many spheres (both coaxially and arbitrarily arranged in space), and can also be used for test calculations during verification numerical solution of these generalized problems.

Authors: Tashrifi Zahra , Mohammadi-Khanaposhtani Mohammad , Biglar Mahmood , Larijani Bagher , Mahdavi Mohammad
Published: July 2019

This review article is focused on the synthesis of compounds with quinazolinones and benzo di/triazepine scaffolds. These invaluable derivatives are of great interest in medicinal and pharmaceutical studies because of their important biological properties. Quinazolinones have diverse applications due to their antibacterial, analgesic, antiinflammatory, antifungal, antimalarial, antihypertensive, CNS depressant, anticonvulsant, antihistaminic, antiparkinsonism, antiviraland and anticancer activities. On the other hand, pharmacological properties of benzodiazepines include antianxiety, anticancer, anticonvulsant, antagonists of cholecystokinin receptors (CCK), antileishmanial, sleep-inducing muscle relaxant and several other useful and interesting properties. As an example, three main categories of drugs, namely anxiolytics, sedative hypnotics (sleep inducers) and anticonvulsants are constructed by 1,4-benzodiazepines. Finally, benzotriazepines are believed to possess various pharmacological properties such as antipsychotic and antitumor activities. Hence, this review is divided into three major sections, considering quinazolinones, benzodiazepines and benzotriazepines. In the first section, we take a brief look at various approaches towards synthesis of substituted quinazolin-4(3H)-ones and 2,3-dihydroquinazolin-4(1H)-ones. Also in this section, we try to give an overview of the synthetic routes and strategies recently reported for the generation of various classes of substituted 4(3H)-quinazolinones and 2,3-dihydroquinazolin-4(1H)-ones. Accordingly, quinazolin-4(3H)-ones, were subdivided into three major classes: 2-substituted, 3-substituted and 2,3-disubstituted-quinazolinones. 2,3- dihydroquinazolin-4(1H)-ones also were subdivided into six sub-categories: 2-monosubstituted, 2,2- disubstituted, 2,3-disubstituted, 1,2,3-trisubstituted, 2,2,3-trisubstituted 2,3-dihydroquinazolin-4(1H)-ones and boron-containing quinazoline-4(1H)-ones. In the other two sections, we cover the literature related to synthesis of benzo di/triazepine. The most recent developments are highlighted with a special emphasis on new synthetic routes based on isatoic anhydride as starting material.
Prevalence and Localization of Hibernating Myocardium Among Patients with Left Ventricular Dysfunction
Authors: Acar Emine , Aksu Ayşegül , Akkaya Gökmen , Kaya Gamze Çapa
Published: July 2019

Objective:

This study evaluated how much of the myocardium was hibernating in patients
with left ventricle dysfunction and/or comorbidities who planned to undergo either surgical
or interventional revascularization. Furthermore, this study also identified which irrigation areas of
the coronary arteries presented more scar and hibernating tissue.

Methods:

At rest, Tc-99m MIBI SPECT and cardiac F-18 FDG PET/CT images collected between
March 2009 and September 2016 from 65 patients (55 men, 10 women, mean age 64±12) were retrospectively
analyzed in order to evaluate myocardial viability. The areas with perfusion defects
that were considered metabolic were accepted as hibernating myocardium, whereas areas with perfusion
defects that were considered non-metabolic were accepted as scar tissue.

Results:

Perfusion defects were observed in 26% of myocardium, on average 48% were associated
with hibernation whereas other 52% were scar tissue. In the remaining Tc-99m MIBI images, perfusion
defects were observed in the following areas in the left anterior descending artery (LAD;
31%), in the right coronary artery (RCA; 23%) and in the Left Circumflex Artery (LCx; 19%)
irrigation areas. Hibernation areas were localized within the LAD (46%), LCx (54%), and RCA
(64%) irrigation areas. Scar tissue was also localized within the LAD (54%), LCx (46%), and RCA
(36%) irrigation areas.

Conclusion:

Perfusion defects are thought to be the result of half hibernating tissue and half scar
tissue. The majority of perfusion defects was observed in the LAD irrigation area, whereas hibernation
was most often observed in the RCA irrigation area. The scar tissue development was more
common in the LAD irrigation zone.
Head and Neck Cancer with Lung Metastases: Treatment Challenges
Authors: Vengathajalam Selvamalar , Lazim Norhafiza Mat
Published: July 2019

Background:

Head and neck cancer has predilection of metastasising to the lung, bones or liver. The site of metastasis usually depends on the primary tumour location, the staging and the regional spread of the tumour. Patients with distant metastasis are predicted to have a poor prognosis with low survival rate. Oligometastasis is the term used for an intermediate biologic state of restricted metastatic capacity with limited number and sites of organ with metastasis. It is also defined by 5 or less than 5 metastatic lesion in a disease with a controlled primary tumour.

Case Reports:

In this case series, we have reported three cases of head and neck carcinomas that pose treatment dilemmas because of lung metastases. First case is a gentleman with laryngeal carcinoma with multiple small lung metastases where the treatment options of surgery versus chemoradiation was debated. The second case is a gentleman with low grade mucoepidermoid carcinoma of the parotid gland with suspicious lung spread of disease. Lastly is a patient with papillary thyroid carcinoma with florid lung metastases who completed chemoradiation.

Conclusion:

The presence of lung metastases does not necessarily mean that the prospect of surviving is poor for the patient. It is necessary to determine the best choice of treatment yielding the best quality of life to maximize the survival period for these patients.

Published: July 2019

Penyelam mengalami penambahan tekanan lingkungan ketika bergerak turun menambah kedalaman penyelaman. Tekanan tersebut menyebabkan volume ruang udara dalam telinga tengah berkurang dan dapat menyebabkan barotrauma dan kerusakan membran timpani. Tekanan tersebut harus diseimbangkan dengan cara melakukan ekualisasi. Ada tiga metode ekualisasi, yaitu metode valsava, toynbee dan menggerakkan rahang. Namun belum diketahui metode mana yang memiliki tingkat keberhasilan tertinggi. Penelitian ini mempelajari tingkat keberhasilan ketiga metode ekualisasi dengan membandingkan kedalaman yang berhasil dicapai oleh penyelam menggunakan tiga metode yang berbeda. Penelitian ini dilakukan pada 40 orang penyelam terlatih di lingkungan kolam air tawar dengan kedalaman 5 meter. Variabel yang diukur adalah angka kedalaman (dalam meter) yang berhasil dicapai penyelam. Hasil penelitian menunjukkan terdapat perbedaan yang signifikan antara capaian kedalaman menggunakan metode valsava dengan capaian kedalaman menggunakan metode toynbee (p<0,05) dan terdapat perbedaan yang signifikan pula antara capaian kedalaman menggunakan metode valsava dengan capaian kedalaman menggunakan metode menggerakkan rahang (p<0,05). Namun tidak didapati adanya perbedaan yang signifikan antara data capaian kedalaman menggunakan metode menggerakkan rahang dengan capaian kedalaman menggunakan metode toynbee (p>0,05). Difference in success rate of 3 equalize method among trained divers in the freshwater environment AbstractDivers experience increase of environmental pressure when the diver descends. This pressure causes the volume of air space in the middle ear to decrease, can cause barotrauma and tympanic damage. This pressure must be equalize. There are three methods of equalization, valsava maneuver, toynbee and moving the jaw. But it is not known which method has the highest success rate. This research studied the success rate of the three methods of equalization by comparing the depth achieved by divers using the three different methods. This study was conducted on 40 trained divers in the freshwater pool with 5 meters depth. The variable measured is the number of depths (in meters) successfully achieved by divers. The results of this study showed that there was a significant difference between the depth achieved using the Valsava maneuver with the depth achieved using the toynbee maneuver (p <0.05) and there were also significant differences between the depth achieved using the Valsava maneuver with depth achieved using the jaw moving method (p <0, 05). However, there was no significant difference between the depth achieved using the jaw moving method with depth achieved using the toynbee maneuver (p> 0.05).

The rapid development of technology offers many advantages to the proses of learning in the classroom. This experimental research aimed to investigates the effectiveness of learning mathematics delivered through blended learning. In particular, this study compared the effectiveness of blended learning using Moodle and traditional one in relation to students’ conceptual understanding. The data was gathered through written test and interview. This study involved 127 students of grade eight secondary school. The data shows that students who learn in blended learning approach have better conceptual understanding rather than their counterparts. The students claim that they can access learning material and revisit some difficult material in their convenience time. Nevertheless, there are some obstacles faced by students related to maintaining their motivation to learn independently and keeping distraction off to access other website when they learn online.Key words: blended learning, conceptual understanding
Experiential meaning breadth variation of British Broadcasting Corporation (BBC) Indonesia online news
Authors: Pratiwi Berlin Insan , Kartikarini Thuthut
Published: July 2019

The aims of this research were to describe experiential meaning variation of English BBC news texts (T1) and Bahasa Indonesia BBC news texts (T2) which were functional grammatically represented in transitivity clause units, to identify the factors that cause the experiential meaning breadth variation of T1-T2, and to map the context of highest variation of T1-T2. This qualitative research applied semantic content analysis of experiential meaning with the researcher as research instrument. The results of this study show that experiential meaning variation of T1-T2 is dominated by highest scale of variation. Transfer-based perspective includes T2 as bad translation, while hermeneutic-based includes T2 as a good translation. Experiential meaning breadth variation of T1-T2 are mainly caused by the ideology of translation of BBC and translators involved in translation process that allows adjustment to the new readership and to the naturalness of the use of Indonesian language to occur. The constrictions of experiential meaning breadth variation mostly are caused by the addition of clause-rank meaning units which are not part of T1 and the existence of summary and/or synthesis of some T1 clause-rank meaning units.
Intercultural language learning in a sister school partnership between Indonesia and Australia
Authors: Iryanti Heni Dwi , Madya Suwarsih
Published: July 2019

This case study aimed to: (1) reveal how intercultural language learning occurred within a sister school partnership in an Indonesian public high school in Yogyakarta, and (2) describe student behaviours perceived to be indicative of intercultural language learning. Using an ethnographic approach through observations and dialogues, this study investigated real life interactions occurring among the research participants within the uniqueness of the partnership between an Indonesian public high school in Yogyakarta and its Australian school partner. The results showed that intercultural language learning occurred in the forms of learning experiences which engaged the students in interaction, observation and reflection with the target community. A number of indicators of intercultural language learning were revealed in the students behaviours within four authentic language experiences including exploring language and culture, noticing verbal and non-verbal cultural behaviours, making connections between home and the target language and culture, and reflecting on the development of a third or intermediate personal position between cultures.

BACKGROUND

Successful integrations of machine learning into routine clinical care are exceedingly rare, and barriers to its adoption are poorly characterized in the literature.

OBJECTIVE

This study aims to report a quality improvement effort to integrate a deep learning sepsis detection and management platform, Sepsis Watch, into routine clinical care.

METHODS

In 2016, a multidisciplinary team consisting of statisticians, data scientists, data engineers, and clinicians was assembled by the leadership of an academic health system to radically improve the detection and treatment of sepsis. This report of the quality improvement effort follows the learning health system framework to describe the problem assessment, design, development, implementation, and evaluation plan of Sepsis Watch.

RESULTS

Sepsis Watch was successfully integrated into routine clinical care and reshaped how local machine learning projects are executed. Frontline clinical staff were highly engaged in the design and development of the workflow, machine learning model, and application. Novel machine learning methods were developed to detect sepsis early, and implementation of the model required robust infrastructure. Significant investment was required to align stakeholders, develop trusting relationships, define roles and responsibilities, and to train frontline staff, leading to the establishment of 3 partnerships with internal and external research groups to evaluate Sepsis Watch.

CONCLUSIONS

Machine learning models are commonly developed to enhance clinical decision making, but successful integrations of machine learning into routine clinical care are rare. Although there is no playbook for integrating deep learning into clinical care, learnings from the Sepsis Watch integration can inform efforts to develop machine learning technologies at other health care delivery systems.

BACKGROUND

Till date no longitudinal prospective study have investigated the association between the oral health status and cognitive decline in the geriatric Indian population, possibly due to past studies differing in target groups and methodologies. We aimed to investigate the association between tooth loss, as evaluated through clinical oral examinations, and the development of cognitive decline in the older adults while considering baseline cognitive function.

OBJECTIVE

to investigate the association between tooth loss, as evaluated through clinical oral examinations, and the development of cognitive decline in the older adults while considering baseline cognitive function.

METHODS

This 5-year prospective cohort study followed 140 participants (mean age: 72.5 ± 4.3 years) without cognitive impairment aged ≥65 years (mean age: 70.9 ± 4.3 years) living in the Dhule Region of Maharashtra , India. Cognitive function was evaluated with the Mini-Mental State Examination (MMSE) in baseline and follow-up surveys,while oral health examination was carried out using Oral Hygiene Index To investigate the association between oral health status and cognitive decline, we applied a multiple logistic regression analysis adjusted for age, gender, hypertension, diabetes, cerebrovascular/cardiovascular disease, hypercholesterolemia, depressive symptoms, body mass index, smoking status, drinking status, duration of education, and baseline MMSE score.

RESULTS

In the 5 years after the baseline survey, we have obtained an overall incidence of 20.71%. population who developed cognitive decline (i.e., MMSE scores of ≤24). Multivariable logistic regression analysis indicated that participants with compromised oral health were more likely to develop cognitive decline than those with mild to moderate oral health were (odds ratio: 3.31; 95% confidence interval: 1.07–10.2). Age, male gender, and baseline MMSE scores were also significantly associated with cognitive decline.

CONCLUSIONS

Poor Oral health status was independently associated with the development of cognitive decline within 5 years among the geriatric population of India . This finding corroborates the hypothesis that oral health may be a predictor or risk factor for cognitive decline.
