Impact of Land Use and Land Cover (LULC) Changes on Carbon Stocks and Economic Implications in Calabria Using Google Earth Engine (GEE).

Terrestrial ecosystems play a crucial role in global carbon cycling by sequestering carbon from the atmosphere and storing it primarily in living biomass and soil. Monitoring terrestrial carbon stocks is essential for understanding the impacts of changes in land use on carbon sequestration. This study investigates the potential of remote sensing techniques and the Google Earth Engine to map and monitor changes in the forests of Calabria (Italy) over the past two decades.

Designing and Testing an IoT Low-Cost PPP-RTK Augmented GNSS Location Device.

Nowadays, the availability of affordable multi-constellation multi-frequency receivers has broadened access to accurate positioning. The abundance of satellite signals coupled with the implementation of ground- and satellite-based correction services has unlocked the potential for achieving real-time centimetre-level positioning with low-cost instrumentation. Most of the current and future applications cannot exploit well-consolidated satellite positioning techniques such as Network Real Time Kinematic (RTK) and Precise Point Positioning (PPP); the former is inapplicable for large user bases due to the necessity of a two-way communication link between the user and the NRTK service provider, while the latter necessitates long convergence times that are not in keeping with kinematic application.

Unveiling the Dynamics of Thermal Characteristics Related to LULC Changes via ANN.

Continuous and unplanned urbanization, combined with negative alterations in land use land cover (LULC), leads to a deterioration of the urban thermal environment and results in various adverse ecological effects. The changes in LULC and thermal characteristics have significant implications for the economy, climate patterns, and environmental sustainability. This study focuses on the Province of Naples in Italy, examining LULC changes and the Urban Thermal Field Variance Index (UTFVI) from 1990 to 2022, predicting their distributions for 2030.

Low-Cost GNSS and PPP-RTK: Investigating the Capabilities of the u-blox ZED-F9P Module.

GNSS has become ubiquitous in high-precision applications, although the cost of high-end GNSS receivers remains a major obstacle for many applications. Recent advances in GNSS receiver technology have led to the development of low-cost GNSS receivers, making high-precision positioning available to a wider range of users. One such technique for achieving high-precision positioning is Precise Point Positioning-Real Time Kinematic (PPP-RTK).

Observation Quality Assessment and Performance of GNSS Standalone Positioning with Code Pseudoranges of Dual-Frequency Android Smartphones.

The new generation of Android smartphones is equipped with GNSS chips capable of tracking multi-frequency and multi-constellation data. In this work, we evaluate the positioning performance and analyze the quality of observations collected by three recent smartphones, namely Xiaomi Mi 8, Xiaomi Mi 9, and Huawei P30 pro that take advantage of such chips. The analysis of the GNSS observation quality implies that the commonly employed elevation-dependent function is not optimal for smartphone GNSS observation weighting and suggests an application of the C/N0-dependent one.

Advantages of Damage Control Strategy With Abdominal Negative Pressure and Instillation in Patients With Diffuse Peritonitis From Perforated Diverticular Disease.

. To evaluate the results of Damage Control Strategy (DCS) in the treatment of generalized peritonitis from perforated diverticular disease in patients with preoperative severe systemic diseases. .

Signal in Space Error and Ephemeris Validity Time Evaluation of Milena and Doresa Galileo Satellites.

In August 2016, Milena (E14) and Doresa (E18) satellites started to broadcast ephemeris in navigation message for testing purposes. If these satellites could be used, an improvement in the position accuracy would be achieved. A small error in the ephemeris would impact the accuracy of positioning up to ±2.

Analysis of the factors influencing the outcome of bleeding of the lower digestive tract. A report of 15 consecutives cases.

The authors present a series of 15 patients with lower gastrointestinal bleeding. 11 (73%) out of 15 patients, were directly subjected to surgery, and 4 (37%) attempted to stop hemorrhage with angiography. In the group of patients undergoing surgery we had a mortality of 1 out of 12 (8%).

Negative pressure therapy alone or with irrigation in the management of severe peritonitis.

Background: Ogilvie was the first to publish on open abdomen (OA) for the treatment of the damages caused by penetrating abdominal wounds in war events. Research improved those devices that allow a controlled, homogeneous and continuous extraction of contaminated fluids from all abdominal recesses, which are nowadays the base of the "Open Abdomen" technique.

Materials And Methods: From August 2012 to February 2016 at the Department of Emergency Surgery of Cardarelli Hospital in Naples, 40 patients affected by Severe Peritonitis have been treated with OA technique.

Acute symptomatic Meckel diverticulum management. Our experience on seven consecutive cases.

Meckel's diverticulum (MD ) is the most common congenital anomaly of the gastrointestinal tract. We revalued clinical records of patients discharged from Unit of Urgent and General Surgery of Highly Specialized Hospital "A.O.

Surgical treatment of non-variceal upper gastrointestinal bleeding: our experience with 1482 patients.

We retrospectively evaluated the medical records of patients admitted to the U.O.C.

[Use of Permacol in complicated incisional hernia].

Polypropylene mesh repair is the gold standard for primary inguinal hernia and incisional hernia. Wound infection and small bowel fistulas are contraindications to polypropylene mesh repair. In addition, synthetic meshes are known to cause severe peritoneal adhesions and enteric fistulas if located close to the bowel.
