13. A 2.4 GHz Coplanar Solar Cell Patch Antenna with a Semi-Analytical Evaluation of Temperature Effects
Abstract Solar cells integrated with antennas have aroused scientific interest as an attractive energy source alternative in low power devices for IoT and Wireless Sensor Network applications. Since the space for all components in the systems is scarce, different integration ideas have been proposed in this field. However, further analysis of the performance

14. Development of a Disposable Pipette Extraction Method Using Coffee Silverskin as an Adsorbent for Chromium Determination in Wastewater Samples by Solid Phase Extraction
A procedure using disposable pipette tips adapted for solid-phase extraction, known as DPX SPE, was used as an alternative way for the chromium determination in wastewater samples. DPX-SPE consists of a device which allows a dynamic contact between the sample and the solid-phase. A residue obtained from the processing of coffee beans, denominate coffee silve

15. Risk of neutropenia among clozapine users and non-users: results from 5,847 patients
Objective: Clozapine is underprescribed due to neutropenia risk. Blood tests every 3 months in those on continuous treatment for > 1 year who have never had an absolute neutrophil count (ANC) < 2,000/µL has been proposed as a monitoring strategy; however, there are no South American data to support this recommendation. This study sought to investigate wheth

16. Chilling requirement of four peach cultivars estimated by changes in flower bud weights
ABSTRACT The adaptation of temperate fruit crops is a challenge being increased by the global warming. Chilling requirement is a key factor for adaptation. The objective of this study was to estimate the chilling requirement of peach cultivars BRS Bonão, Esmeralda, Granada and Eragil, using the Tabuenca test. Chilling accumulation was computed using four di

17. Prognostic importance of expression of mini-chromosome maintenance proteins (MCMs) in patients with nasopharyngeal cancer treated with curative radiotherapy
Abstract Objective: The prognostic importance of minichromosome maintenance complex expression in nasopharyngeal cancer is still unknown. We aimed to find whether minichromosome maintenance complex 2–7 expression may potentially be used to predict the prognosis of nasopharyngeal cancer patients treated with definitive radiotherapy. Methods: Between April

19. TEST OF THE SCREENING AND PARAMETER OPTIMIZATION OF SWING SEPARATION SIEVE IN FIELD OPERATION
ABSTRACT The need for clarity regarding the sieving characteristics of the potato-soil mixture, as provided by the swing separating sieve of a potato digger, as well as the derived problems of low potato transportation efficiency, a high potato damage rate and low potato unearthing rate, are the main reasons for this study. Dynamic tracking technology is pro

20. Stress fractures
ABSTRACT Stress fractures (SF) represent 10%-20% of all injuries in sport medicine. An SF occurs when abnormal and repetitive loading is applied on normal bone: The body cannot adapt quickly enough, leading to microdamage and fracture. The etiology is multifactorial with numerous risk factors involved. Diagnosis of SF can be achieved by identifying intrinsic

21. Inflammatory cytokines and alcohol use disorder: systematic review and meta-analysis
Objective: To assess differences in blood inflammatory cytokines between people with alcohol use disorder (AUD) and healthy controls (HC). Methods: Searches were performed from inception through April 14, 2021. Meta-analyses with random-effects models were used to calculate the standardized mean difference ([SMD], 95%CI), and potential sources of heterogene

22. Robotic-assisted nephrectomy with level II IVC thrombectomy using Rummel Tourniquets
ABSTRACT Background: Inferior vena cava (IVC) invasion from renal cell carcinoma (RCC) occurs at a rate of 4-10% (1). IVC thrombectomy (IVC-TE) can be an open procedure because of the need for handling of the IVC (2). The first reported series of robotic management of IVC-TE started in 2011 for the management of Level I - II thrombi with subsequent case rep
