Published: April 2019

Abstract.In the agriculture sector, an essential task of spraying uncrewed aerial vehicles (UAVs) is to return as soon as the farmland border is reached. Initially, they need to be manually controlled which is a tedious job. This article presents an efficient image processing algorithm to automatically detect farmland borders based on the images received from the airborne cameras. First, the steerable-filter-based surrounded inhibition method was adopted to detect major borders, and then the images were thinned and binarized using non-maxima suppression (NMS) and hysteresis thresholding, respectively. Secondly, the results with different inhibition coefficients were fused, and the burrs were trimmed. Then the breakpoints were connected using a seed growing method. Finally, an improved Markov Random Field (MRF) model based on line segments was proposed to screen out fake borders. The result of classification depends on the maximum length of the retained segment. The experimental results and offline field tests showed that the proposed algorithm could accurately detect farm borders of different types from a complex farmland image. The average detection accuracy and completeness of the proposed algorithm is 85.6% and 83.6%, respectively. Compared with other methods, the proposed algorithm is highly reliable, robust, and scalable to other applications. Keywords: Agricultural spraying UAVs, Cross-border detection, Markov Random Field (MRF), Steerable filters, Surround suppression.

Published: April 2019

Abstract.To improve the cleaning performance of oat sorting devices with a single-fan three-cylinder screen system, this study investigated the airflow velocity field of a cleaning machine using particle image velocimetry (PIV) technology. Specifically, an optimal cleaning performance can be described as one with no material idling under the optimal operating parameters of the oat cleaning machine, the measured airflow velocity field space is divided into nine representative longitudinal planes that can reflect airflow velocity characteristics in the longitudinal plane. The results showed that a phenomenon of airflow backflow occurred in the radial direction above the medium cylinder screen, the airflow velocity in each longitudinal section of the airflow velocity field was less uniform in the transverse distribution, a. The movement of oat extracts in the cleaning room was recorded by a high-speed digital video camera. The phenomenon of oat impurities moving along the airflow backflow direction, and a transverse flow irregularity appearing in the radial direction above the medium cylinder screen were observed. The grain loss rate and impurity rate of the oat cleaner were 1.53% and 1.25%, respectively, under optimal conditions. Therefore, to improve the cleaning performance of the cleaner, it is necessary to theoretically analyze the phenomenon of airflow backflow in the cleaner, which can provide a reference for the follow-up design and optimization of the structure of the cleaner.

Published: April 2019

Abstract. This 2-yr study analyzed the effects of different irrigation regimes of drip irrigation under plastic film on sugar beet production in Xinjiang, China, and established a binary quadratic regression equation and normalization to describe the maximum root yield, sugar yield, and water use efficiency. Three irrigation frequencies (10, 11, and 12 d) and two irrigation water quotas (45 and 60 mm) were combined to form six treatments. Irrigation frequency had a significant effect on root yield at 1% level of significance in both years, but the effects on sugar yield and water use efficiency were nonsignificant. In both years, the sugar yield resulting from 60 mm irrigation water quota at frequency of 11 d increased by 10.8% and 6.5%, respectively, compared with that resulting from 45 mm irrigation water quota at frequency of 11 d. The regression equation based on the experimental observations indicated that in Xinjiang the optimal irrigation regime was 11 d and 55 mm which saved 21.2% irrigation water for the highest sugar beet yield. The data optimization to determine the weight of roots and evapotranspiration found that root growth exhibited a pattern similar to the aboveground crop growth, and the root growth was most rapid in the period 30 July to 10 August. Keywords: Irrigation frequency, Irrigation water quota, Optimal irrigation regime, Root growth, Root yield, Sugar yield, Water use efficiency.
Risk of Mortality and Hospitalization After Post-Pancreatitis Diabetes Mellitus vs Type 2 Diabetes Mellitus: A Population-Based Matched Cohort Study
Authors: Cho Jaelim , Scragg Robert , Petrov Maxim S. 
Published: April 2019

Objectives:
To investigate the risk of mortality and hospitalization in individuals with post-pancreatitis diabetes mellitus (PPDM) compared with those with type 2 diabetes mellitus (T2DM).

Methods:
Using nationwide hospital discharge data on pancreatitis and diabetes in New Zealand (n = 231,943), a total of 959 individuals with PPDM were identified. For each individual with PPDM, 10 age- and sex-matched individuals with T2DM were randomly selected. Multivariable Cox regression analysis was conducted, and the risk was expressed as hazard ratio (HR) and 95% confidence interval (CI).

Results:
A total of 3,867 deaths occurred among 10,549 study individuals. Individuals with PPDM had all-cause mortality rate at 80.5 (95% CI, 70.3–90.6) per 1,000 person-years, which was higher compared with T2DM individuals (adjusted HR, 1.13 (95% CI, 1.00–1.29); absolute excess risk, 14.8 (95% CI, 4.5–25.2) per 1,000 person-years). Compared with T2DM, PPDM was associated with higher risks of mortality from cancer (adjusted HR, 1.44; 95% CI, 1.13–1.83), infectious disease (adjusted HR, 2.52; 95% CI, 1.69–3.77), and gastrointestinal disease (adjusted HR, 2.56; 95% CI, 1.64–4.01). Individuals with PPDM vs T2DM were also at significantly higher risks of hospitalization for chronic pulmonary disease, moderate to severe renal disease, and infectious disease.

Conclusions:
Individuals with PPDM have higher risk of mortality and hospitalization compared with individuals with T2DM. Guidelines for management of PPDM need to be developed with a view to preventing excess deaths and hospitalizations in individuals with PPDM.

Authors: Boyer Graham , Caulfield Timothy , Green Peter H. R. , Lebwohl Benjamin 
Published: April 2019

INTRODUCTION:
We identified the frequency and assessed the validity of marketing claims made by American chiropractors, naturopaths, homeopaths, acupuncturists, and integrative medicine practitioners relating to the diagnosis and treatment of celiac disease and nonceliac gluten sensitivity (NCGS), both of which have increased in prevalence in recent years.

METHODS:
We performed a cross-sectional study analyzing websites of practitioners from 10 cities in the United States and analyzed the websites for any mention of celiac or NCGS as well as specific claims of ability to diagnose, ability to treat, and treatment efficacy. We classified treatments promoted as true, false, or unproven, as assessed independently by 2 authors.

RESULTS:
Of 500 clinics identified, 178 (35.6%) made a claim regarding celiac disease, NCGS, or a gluten-free diet. Naturopath clinic websites have the highest rates of advertising at least one of diagnosis, treatment, or efficacy for celiac disease (40%), followed by integrative medicine clinics (36%), homeopaths (20%), acupuncturists (14%), and chiropractors (12%). Integrative medicine clinics have the highest rates of advertising at least one of diagnosis, treatment, or efficacy for NCGS (45%), followed by naturopaths (37%), homeopaths (14%), chiropractors (14%), and acupuncturists (10%). A geographic analysis yielded no significant variation in marketing rates among clinics from different cities. Of 232 marketing claims made by these complementary and alternative medicine (CAM) clinic websites, 138 (59.5%) were either false or unproven.

DISCUSSION:
A significant number of CAM clinics advertise diagnostic techniques or treatments for celiac disease or NCGS. Many claims are either false or unproven, thus warranting a need for increased regulation of CAM advertising to protect the public.
Intussusception After Pancreaticoduodenectomy
Authors: Patel Kishan , Luthra Anjuli , Aberra Fasika , Lara Luis F. , Gray Darrell 
Published: April 2019

ABSTRACT
Intussusception after pancreaticoduodenectomy (Whipple procedure) is exceedingly rare. We present a case of retrograde jejunal intussusception into the gastric lumen in a patient who previously underwent Whipple procedure. Diagnostic endoscopy may serve to confirm intussusception, identify a potential lead point, and, in some cases, endoscopically reduce the intussusception. Ultimately, however, surgical management is recommended due to a high rate of recurrence along with the potential to detect a lead point and associated malignancy.
A Balanced Dual-Band BPF Based on C-CSRR with Improved Passband Selectivity
Authors: Chen Lei , Xiao Qin Kun , Gan Yan Ni 
Published: April 2019

Abstract
A balanced dual-band bandpass filter (BPF) is proposed by embedding two nested coupled complementary split-ring resonators (C-CSRRs) into a H-type balanced stepped-impedance slotline resonator in this paper. C-CSRR is composed of a complementary split-ring resonator (CSRR) with a pair of coupling slotlines in the open end, which can generate a bandpass response. In order to improve the passband selectivity further, source-load-coupled structure is employed. Moreover, it can be found that the proposed BPF has a wideband common-mode (CM) suppression, which is independent from the differential-mode (DM) passbands. Therefore, the design procedure can be significantly simplified. In order to validate its practicalbility, one balanced dual-band BPF is fabricated. The predicted results on S parameters are compared with the measured ones and a good agreement is found.
Reframing the Arabic Narratives on Daesh in the English Media: The Ideological Impact

Published: April 2019

AbstractThis paper discusses the dynamic role of translators in possibly promoting certain ideologies and political agendas by presenting stories through the lens of an ideologically laden meta-narrative. It compares the representation of ‘Daesh’ in the narratives of Arabic editorials and their English translations published by the Middle East Media Research Institute (MEMRI). MEMRI is a pro-Israeli organization, widely cited by leading Western media outlets, especially in the US. The study adopts the narrative theoryinformed analysis of Baker (2006) as its theoretical framework to examine how narrative is used to legitimize, normalize, and justify certain actions to the public. The findings suggest that through translation, MEMRI draws upon the meta-narrative of the War on Terror in furthering its ideologically laden agenda of terrorist Arabs and Muslims by publishing selective and decontextualized excerpts and mistranslation of concepts such asDaesh (داعش),Jihad(جهاد), andJizya(جزية).

El enfermo venéreo, ¿víctima o criminal? El delito de contagio venéreo en México en la primera mitad del siglo xx
Authors: Ramírez María del Carmen Zavala 
Published: April 2019

La lucha antivenérea en México evidenció ambivalencias frente a los enfermos, en ocasiones vistos como víctimas dignas de compasión y otras tantas como criminales merecedores de castigo. La legislación penal tipificó el delito de contagio venéreo (1929 y 1931) y permitió la intervención estatal sobre los cuerpos de los enfermos para determinar su inocencia o culpabilidad. El artículo analiza los debates médicos acerca de la penalización del contagio venéreo. Asimismo, presenta el estudio de cuatro juicios de amparo por este delito en los que quedaron de manifiesto ideas, valores y representaciones sobre la sexualidad masculina y femenina.
The struggle against venereal disease in Mexico demonstrates ambivalence towards sick people, who are sometimes regarded as victims in need of compassion and at other times as criminals who deserve punishment. The penal code classified the crime of venereal contagion (1929 and 1931) and allowed state intervention in relation to the bodies of ill people in order to establish their innocence or culpability. This article analyzes medical debates around the criminalization of venereal contagion. As evidence, it presents a study of four cases of protection for this crime which demonstrate the ideas, values and representations of masculine and feminine sexuality.

AbstrakRendahnya produktivitas lahan pertanian di Indonesia berkaitan dengan serangan penyakit tanaman, contohnya penyakit layu Fusarium pada tanaman tomat dan busuk pangkal batang pada tanaman kelapa sawit yang disebabkan oleh Ganoderma boninense. Penelitian sebelumnya telah berhasil mengisolasi aktinomisetes dari tanah Arboretum Universitas Riau, namun belum diketahui kemampuannya dalam menghambat jamur Fusarium oxysporum f.sp lycopersici dan Ganoderma boninense. Penelitian ini bertujuan untuk menguji 32 isolat aktinomisetes terhadap jamur target dengan metode difusi agar. Aktinomisetes potensial yang terpilih, dilanjutkan untuk produksi senyawa antifungi dengan lama waktu fermentasi yang berbeda (4, 5, dan 6 hari) dan diuji dengan metode difusi kertas cakram. Hasil penelitian uji aktivitas antifungi dengan metode difusi agar menunjukkan 31 isolat aktinomisetes mampu menghambat pertumbuhan jamur F. oxysporum f.sp lycopersici dan isolat A2.01 memiliki zona hambat tertinggi yaitu sebesar 36,10 mm. Sebanyak 28 isolat aktinomisetes mampu menghambat jamur G. boninense dan isolat D2.28 memiliki zona hambat tertinggi, yaitu sebesar 45,71 mm. Isolat aktinomisetes Arboretum Universitas Riau sebagian besar dapat menghambat pertumbuhan kedua jamur target dengan metode difusi agar, namun hasil uji senyawa antifungi isolat potensial dengan metode difusi kertas cakram belum mampu membentuk zona hambat. Isolat aktinomisetes potensial dapat diaplikasikan menggunakan kultur langsung secara in vivo.Abstract The low productivity of agricultural land in Indonesia occurred because of plant diseases attack such as Wilt Fusarium in tomato plant and Basal Stem Rot disease in palm oil caused by Ganoderma boninese. Previous research had successfully isolated the actinomycetes from soil of Arboretum University of Riau However, the antifungal potency of those isolates against Fusarium oxysporum f. sp lycopersici and Ganoderma boninense had not been known. This research aimed to screening 32 actinomycetes isolates against the fungal target by using agar diffusion method. The selected actinomycetes were continued to produce crude antifungal by different duration of fermentation (4, 5 and 6 days) using disc diffusion method. The result of the antifungal activity using agar diffusion method showed that there were 31 isolates that able to inhibit the F. oxysporum f. sp lycopersici and isolate A2.01 showed the highest inhibition zone by 36.10 mm. There were 28 isolates that able to inhibit the G. boninense and isolate D2.28 showed the highest inhibition zone by 45.71 mm. Almost all of the isolate was able to inhibit both of two fungals targets with diffussion agar method, but the crude antifungal compound of the potential isolate by disc diffusion method could not inhibit both of the fungal targets. The potential actinomycetes isolate was suggested to be applied as a culture directly in vivo.

Abstract

Background
Hyperparathyroidism is both underdiagnosed and undertreated, but the reasons for these deficiencies have not been described. The purpose of this study was to identify reasons for underdiagnosis and undertreatment of hyperparathyroidism that could be addressed by targeted interventions.

Materials and Methods
We identified 3,200 patients with hypercalcemia (serum calcium &gt;10.5 mg/dL) who had parathyroid hormone (PTH) levels evaluated at our institution from 2011 to 2016. We randomly sampled 60 patients and divided them into three groups based on their PTH levels. Two independent reviewers examined clinical notes and diagnostic data to identify reasons for delayed diagnosis or referral for treatment.

Results
The mean age of the patients was 61 ± 16.5 years, 68% were women, and 55% were white. Fifty percent of patients had ≥1 elevated calcium that was missed by their primary care provider. Hypercalcemia was frequently attributed to causes other than hyperparathyroidism, including diuretics (12%), calcium supplements (12%), dehydration (5%), and renal dysfunction (3%). Even when calcium and PTH were both elevated, the diagnosis was missed or delayed in 40% of patients. For 7% of patients, a nonsurgeon stated that surgery offered no benefit; 22% of patients were offered medical treatment or observation, and 8% opted not to see a surgeon. Only 20% of patients were referred for surgical evaluation, and they waited a median of 16 months before seeing a surgeon.

Conclusion
To address common causes for delayed diagnosis and treatment of hyperparathyroidism, we must improve systems for recognizing hypercalcemia and better educate patients and providers about the consequences of untreated disease.

Implications for Practice
This study identified reasons why patients experience delays in workup, diagnosis, and treatment of primary hyperparathyroidism. These data provide valuable information for developing interventions that increase rates of diagnosis and referral.
La poesía mexicana en la "Gazeta de México" a finales del siglo XVIII. Entre la herencia barroca y la Ilustración
Authors: Paniagua Blanc Marina 
Published: April 2019

RESUMENLa "Gazeta de México" no fue una revista literaria y solo en ciertas ocasiones publicó alguna poesía; sin embargo recogió mucha información sobre esa temática y actuó como propagandista de ediciones de obras, certámenes, censuras, etc. A través de esa información podemos acercarnos al panorama literario novohispano, en un momento de auge del Neoclasicismo. La publicación mostró un especial interés por la poesía laudatoria y épica relacionada con los acontecimientos de la monarquía; también por algunos autores clásicos como Virgilio y Horacio y sus traductores, así como por Tomas de Iriarte. Todo ello sin olvidar el importante papel de los jesuitas en el exilio. Los asuntos poéticos, por tanto, fueron más de información que de reproducción.PALABRAS CLAVE"Gazeta de México", Poesía, Fábulas, Tradición clásica, Nueva España, Siglo XVIII.
