Abstract:

It is important to understand the distribution of irrigated and non-irrigated vegetation in rapidly expanding urban areas that are experiencing climate-induced changes in water availability, such as Los Angeles, California. Mapping irrigated vegetation in Los Angeles is necessary for developing sustainable water use practices and accurately accounting for the megacity’s carbon exchange and water balance changes. However, pre-existing maps of irrigated vegetation are largely limited to agricultural regions and are too coarse to resolve heterogeneous urban landscapes. Previous research suggests

High spatial resolution maps of Los Angeles, California are needed to capture the heterogeneity of urban land cover while spanning the regional domain used in carbon and water cycle models. We present a simplified framework for developing a high spatial resolution map of urban vegetation cover in the Southern California Air Basin (SoCAB) with publicly available satellite imagery. This method uses Sentinel-2 (10–60 × 10–60 m) and National Agriculture Imagery Program (NAIP) (0.6 × 0.6 m) optical imagery to classify urban and non-urban areas of impervious surface, tree, grass, shrub, bare soil/no

Gastroesophageal reflux disease (GERD) is a common disease with high prevalence, and its endoscopic severity can be evaluated using the Los Angeles classification (LA grade).

The proposed model employs a data augmentation technique, a two-stage no-freezing fine-tuning policy, and an early stopping criterion. As a result, the proposed model exhibits high generalizability.

A 63-yo patient with no complaints in a proton pump inhibitor (PPI) therapy was admitted for a follow-up examination for BO-complicated GERD using oesophagogastroduodenoscopy (OGDS) with biopsy, high-resolution oesophageal manometry and 24-h pH-impedance. Endoscopy revealed signs of BO (long segment C1M3), erosive reflux oesophagitis (grade B in Los Angeles class

Abstract:

Preliminary isoseismals for Modified Mercalli intensities are presented for the Whittier Narrows Earthquake. Isoseismals for intensities VI and lower are based on responses to a mail survey. Intensity VII and larger are based on a field survey of damage described in this paper. The maximum observed intensity of VIII was confined to Whittier. The shapes of the intensity contours compare favorably with the distribution of average peak acceleration data from the strong motion array in the greater Los Angeles area. The damage assessments appeared consistent with earthquake magnitude. However, the

ABSTRACT BACKGROUND: The gastroesophageal reflux disease (GERD) is the most common esophageal disease in medical practice, and it is suspected according to patients’ symptoms. GERD can be classified in erosive esophagitis (EE) according to the presence of upper gastrointestinal endoscopy findings. OBJECTIVE: To evaluate endoscopic findings in patients with symptoms suggestive of GERD comparing epicemiological and risk factors. METHODS: Upper endoscopy reports were examined retrospectively from patients with symptoms of GERD such as heartburn, regurgitation, cough, throat clearing, globus and c

Abstract:

Background Acromioclavicular joint separations are very common lesions, with the majority falling into Rockwood classification type I and II. It is generally agreed that conservative treatment of these injuries leads to good functional results, although there are some studies that suggest these injuries are associated with a high incidence of persistent symptoms. Hypothesis Type I and II acromioclavicular joint disruption significantly impairs long-term shoulder function. Study Design Case series; Level of evidence, 4.

A Williams, who first described ‘oboyerite’) were analysed in this study. The discreditation of ‘oboyerite’ as a valid mineral species has been approved by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association (Proposal 19-D).

We have devised a funnel-shaped transparent cap for the endoscopic diagnosis and treatment of stenosis in the digestive tract. This funnel-shaped cap is made of highly transparent methacrylic resin. A 73-year-old woman with reflux esophagitis (categorized as grade D by the Los Angeles Classification) visited our hospital with the chief complaint of dysphagia. She was examined using an endoscope equipped with a transparent vinyl chloride hood at its tip. Many pieces of food were found to be trapped in the esophagus. These were removed using tripod forceps or aspirated into the hood. The interna

Background : Obesity is correlated with several comorbidities, including gastroesophageal reflux disease. Its main complications are detectable by endoscopy: erosive esophagitis and Barrett's esophagus. Aim : To correlate erosive esophagitis and hiatal hernia with the degree of body mass index (BMI). Method : Was performed a retrospective analysis of 717 preoperative endoscopic reports of bariatric patients. Fifty-six (8%) presented hiatal hernia, being 44 small, nine medium and five large.
