Literature Review
Authors: Luo Xiu-Qin , Qi Wan-Ling , Liu Qian , Zeng Qing-Yun , Luo Zhe-Huang
Published: May 2024

Introduction:

Angiomatoid fibrous histiocytoma (AFH) is a borderline tumor usually affecting the the children or young adults. 18F-Fluorodexoyglucose (FDG)
positron emission tomography/computed tomography (PET/CT) investigations of pulmonary AFH are rare, and there are currently no reports of
intense FDG uptake in AFH.

Case Report:

We report an AFH that occurred in the lung of a 57-year-old woman. She presented with paroxysmal cough and occasional bloodshot sputum. 18FFDG
PET/CT revealed a right parahilar nodule with intense FDG-avidity, middle lobe atelectasis, and several bilateral axillary lymph nodes with
mild hypermetabolic activity. This patient underwent a right middle lobe lobectomy via video-assisted thoracoscopy. Histopathologically, the
diagnosis was pulmonary AFH. She had an uneventful postoperative course, and the bilateral axillary lymph nodes regressed during postoperative
follow-up.

Conclusions:

The clinical presentation and image findings of patients with primary pulmonary AFH may be potential diagnosis pitfalls. The diagnosis of lymph
nodes or distant metastases should be approached with caution. To avoid misdiagnosis, biopsy with histological examination and
immunohistochemichal staining should be performed as early as possible.

Coal is mostly stored in coal bunkers. As the amount of coal in the bunker increases, the
concentration of coal dust inside the bunker also increases, making it susceptible to accidents such as
fires and explosions. Additionally, the leakage of coal dust particles can cause significant environmental
pollution in the surrounding area, leading to resource wastage. To improve energy efficiency,
reduce material transport dust concentration, and protect the surrounding environment, the efficient,
energy-saving, and environmentally friendly characteristics of pneumatic conveying systems are
utilized. This is achieved through the use of anti-dust telescopic pipeline equipment (DTPE), which
effectively prevents external dust particles from entering the telescopic pipeline, thus reducing mechanical
wear. In environments with high coal dust concentration, a coal particle pneumatic conveying
storage system based on DTPE is used to extend the service life of pneumatic conveying pipelines
and effectively reduce the coal dust concentration within the storage bin. This study reviews the
patents and research achievements of scholars in the field of pneumatic conveying and focuses on the
anti-dust telescopic pipeline equipment (DTPE) and the coal particle pneumatic conveying storage
system based on DTPE. Experiments using pneumatic conveying, screw conveyors, and belt conveyors
are conducted to compare conveying time and efficiency. Dust reduction experiments are
carried out in the coal bunker to verify the dust reduction effect of the coal particle pneumatic conveying
storage system based on DTPE. The anti-dust telescopic pipeline equipment (DTPE) features
a telescopic shell to protect the telescopic pipeline, effectively reducing mechanical wear caused by
coal particles entering the gaps in the pipeline during pneumatic conveying. The coal particle pneumatic
conveying storage system based on DTPE includes a cyclone dust removal system and a dynamic
monitoring system, which monitors the temperature inside the bin and reduces the coal dust
concentration, thereby minimizing the occurrence of safety accidents. Through experimental verification,
the coal particle pneumatic conveying storage system based on DTPE is found to be suitable
for environments with high coal dust concentrations. The anti-dust telescopic pipeline equipment
(DTPE) and the coal particle pneumatic conveying storage system based on DTPE achieve the automated
feeding, dust removal, return, and discharge of coal particles. They offer advantages such as
high system automation, minimal environmental pollution, and high coal transport rates, providing
design references for the pneumatic conveying of coal and other ore particle materials.

Vannamei (Litopenaeus vannamei) Peeled Deveined Tail-On (PDTO) shrimp is frozen shrimp product consumers highly preferred. However, shrimp products are easily perishable that require a proper cold chain system to preserve their quality, shelf life, and nutritional value. This study investigated the cold chain implementation of PDTO shrimp processing in the fishery industry. The temperature of shrimp products, water, and rooms was monitored during processing. Results showed that the shrimp temperature measured in each process was below 5°C. However, abusive temperatures were detected in water used in the peeling and deveining step and soaking process, while water and shrimp temperatures altered each other. Moreover, room temperatures were recorded under 20°C, conforming to Ministry of Marine and Fisheries regulations. Air Blast Freezer and cold storage temperatures revealed that ABF and CS could not meet the company’s temperature standards. These findings may help shrimp companies monitor steps indicating to have temperature abuse attentively.

Published: May 2024

Introduction. The tendency of microorganisms to develop resistance mechanisms is a widely discussed and signiﬁcant problem worldwide. Studying regional diﬀerences in the qualitative characteristics of microorganisms provides valuable information for empirically preventing and treating infectious complications, as well as providing an enhanced understanding of the variability in microbial community properties within the clinical context of diseases and patients' comorbidity status.

Objective. To assess the antibiotic resistance of microorganisms isolated in high titers from the urine samples of patients with benign prostate hyperplasia (BPH) prior to surgery.

Materials & Methods. This single-center, retrospective study conducted from March 2016 to February 2023 included 59 suprapubic-draining BPH-patients (Group I), 46 drainage-free BPH-patients with leukocyturia (Group II), and 44 drainage-free BPH-patients and no leukocyturia (Group III). Inclusion criteria: indications for BPH surgery, no history of sexually transmitted diseases, no symptoms of urinary tract infection, and no prostate cancer. The patient's voluntary informed consents to participate were also obtained.

Results. The rates of resistance to ciproﬂoxacin in patients of Group I were statistically signiﬁcantly higher compared to Group II (85.7% vs 55.6%, p = 0.002). Resistance of gram-negative microorganisms to meropenem and imipenem was higher in Group III compared to Group I (31.1% vs 13.7%, p = 0.006 for meropenem and 44.5% vs 9.8%, p = 0.001 for imipenem, respectively). Resistance of Gram-positive microorganisms to ampicillin in Groups I to III was 13.6%,

6.3% and 20.0%, respectively with no signiﬁcant diﬀerence between groups (p > 0.05). However, there was extremely high resistance among veriﬁed Gram-positive organisms to all the drugs in the ﬂuoroquinolone class (ciproﬂoxacin, norﬂoxacin, levoﬂoxacin) ranged from 63.6% to 80.0%.

Conclusion. The present study demonstrates that the isolation frequency of antibiotic-resistant microorganisms from the urine sample of drainage-free BPH-patients or no clinical and laboratory signs of inﬂammation in the urinary tract is high. The presence of antibiotic resistance provides risks for developing diﬃcult-to-control infectious complications. Currently, assessment of urine-derived microbial antibiotic resistance should be considered in every BPH-patient with indications for surgical management of bladder outlet obstruction, regardless of the presence of risk factors.

Introduction. Analysis of complications after transurethral surgery for benign prostate hyperplasia (BPH) demonstrates that 20 – 30% of patients require prolonged postoperative treatment for severe lower urinary tract symptoms (LUTS) despite improvements in technology and surgical techniques. These complications play a signiﬁcant role in reducing the quality of life of patients in the postoperative period. Severe storage symptoms and urgent urinary incontinence represent signiﬁcant challenges in the postoperative phase when performing laser enucleation surgery. There are also limits to standard approaches to perform laparoscopic prostatectomy, which requires the development of improved techniques.

Objective. To conduct a comparative assessment of the postoperative dynamics of LUTS in groups undergoing holmium laser enucleation of the prostate (HoLEP), a standard Millin laparoscopic simple prostatectomy (LSP), and a modiﬁed LSP.

Materials & Methods. This multicenter study included 439 patients who were randomly assigned to 3 groups depending on the surgical treatment technique used for bladder outlet obstruction associated with large-volume BPH: the HoLEP group (n = 151), the standard Millin LSP (n = 142) and the modiﬁed LSP, combined with temporary clamping of the internal iliac arteries and vesicourethral anastomosis (n = 146). The main criterion assessed during six-months follow-up was the severity of LUTS on the IPSS scale (obstructive and irritative components). Complications that developed during the postoperative observation period were recorded.

Results. A lower severity of LUTS was revealed in the group of the modiﬁed LSP compared to the standard LSP and HoLEP (p = 0.041 and p = 0.001, respectively). The average irritative component of IPSS was signiﬁcantly lower in the modiﬁed LSP group compared to the standard LSP and HoLEP (p = 0.032 and p = 0.001, respectively). The observed trend continued to the third month after surgery. Comparison of changes in symptom severity six months after surgery demonstrated a signiﬁcant advantage for the modiﬁed LSP both compared to HoLEP (p = 0.017) and a standard LSP (p = 0.032). All three groups showed comparable signiﬁcant improvements in quality of life.

Conclusion. The severity of postoperative storage symptoms is a limitation of HoLEP use, whereas the standard LSP is associated with lower severity of LUTS. The authors' modiﬁcation of the LSP has the potential to reduce the severity of storage symptoms in patients for up to three months after surgery, and is associated with a low rate of urge incontinence.

Authors: Wan Zakaria Wan Zafira Ezza , Kassim Mohd Asyraf , Mohd Radzi Muhammad and Arif Hakimi
Published: May 2024

This paper evaluates the potential of Chlorella sp. microalgae biomass as a feedstock for biosuccinic acid (bio-SA) production via the fermentation process. In this study, the biomass was pretreated and hydrolyzed using a mild acid before being fermented with Actinobacillus succinogenes. The influence of the initial biomass concentration and agitation rate on bio-SA production during batch fermentation was evaluated using a Response Surface Methodology (RSM) design. The results of the study indicated that Chlorella sp. microalgae biomass contained various types of sugars, with glucose identified as the dominant reducing sugar in the Chlorella sp. hydrolysate. According to the RSM analysis, the study showed that changes in the initial biomass concentration and agitation rate could significantly affect bio-SA production from Chlorella sp. hydrolysate. The highest bio-SA concentration of 14.56 g/L with a yield of 0.62 g/g was achieved when fermentation was performed using 10% (w/v) biomass at 150 rpm. Therefore, this study suggests that Chlorella sp. hydrolysate can be an alternative and renewable feedstock for efficient bio-SA production.

Published: May 2024

This study aims to analyze the struggle of sexual harassment victims depicted in the film entitled Penyalin Cahaya. This study uses Fairclough’s critical discourse analysis (CDA) model and the Outrage Management model (Scott & Martin, 2006) to examine the verbal and visual aspects of the film. The dimensions that are analyzed include the text, the discourse practice, and sociocultural practice. The key dialogues and scenes are extracted by selecting and retrieving excerpt of dialogues and scenes which depict conflict and power imbalances between the victims and the perpetrators. The results show that power imbalance and its manifestation between them can be found by observing the dialogue and the scenes. It demonstrates that there are several ways through which the abusers exercise their power over the victims. It also highlights the attempts by the victims to fight against sexual harassment, which is often ignored. Furthermore, the sociocultural state of Indonesian society, especially regarding patriarchal culture and power struggles over women, became the main driver that led to the production of this film. The significance of this study is that it can provide insight into the positions, emotions, and obstacles faced by sexual harassment victims in Indonesia, as depicted in the film.

Social Interaction and Class Struggles in Noughts & Crosses by Malorie Blackman
Authors: Rahmawati Aulia Nur , Saktiningrum Nur
Published: May 2024

This research employs a sociological approach to literature, drawing on Georg Simmel's social interaction theory and Karl Marx's class struggle concepts, to analyze the dynamics between the upper-class Crosses and the lower-class Noughts in the novel Noughts & Crosses. The study identifies five forms and six types of social interactions, encompassing superordination and subordination, exchange, conflict, prostitution, and sociability, along with character-based classifications such as the miser, the spendthrift, the stranger, the adventurer, the nobility, and the poor. The central focus lies in understanding the struggles of the Noughts in their pursuit of social equality within a deeply divided society. Despite collective and individual efforts, fueled by class consciousness and the formation of the Liberation Militia, the research concludes that achieving equality remains elusive. The powerful Crosses, driven by hidden manipulations and a desire to maintain the existing system, thwart the Noughts' endeavors, underscoring the persistent challenges faced by the lower class in a society marked by reverse racism.
The Counter-Stereotypical Representation of Latinas in the American Police Procedural Comedy Series Brooklyn Nine-Nine (Fox & NBC, 2013-2021)
Authors: Putri Naily Ananda , Primasita Fitria Akhmerti
Published: May 2024

The representation of Latinas in America has always been stapled with stereotypical traits since their initial appearance in the mainstream media because the representation is depicted from the point of view of Anglo-Americans. It is then intriguing to analyze the representation of Latinas in the American police procedural comedy series Brooklyn Nine-Nine which its Anglo-American producers claimed to be counter-stereotypical to the existing Latina representation in the American mainstream media. Using Roland Barthes' Semiotics, the analysis shows that these characters defy traditional roles by being depicted as competent, assertive professionals with legal citizenship. The findings show that these characters defy traditional roles by being depicted as competent, assertive professionals with legal citizenship. They also diverge from sexualized stereotypes through their portrayal as authoritative figures, avoiding overly sexualized tropes in speech and attire. This portrayal offers a counter-narrative to existing media stereotypes of Latina women.
EXPERIMENTAL ANALYSIS OF THE EFFECT OF THE WOVEN ARAMID FABRIC ON THE STRAIN TO FAILURE BEHAVIOR OF PLAIN WEAVED CARBON/ARAMID HYBRID LAMINATES
Authors: Zachariah Sojan Andrews , Shenoy Satish , Pai Dayananda
Published: May 2024

Remarkable advances in the research and development of micro/mini Unmanned Aerial Vehicles (UAVs) seek thin, lightweight and strong materials for their structural applications. As these structures involve various loading conditions in both the in-plane and through-the-thickness directions during their life cycle, the assurance of the structural stability in each direction is deemed mandatory. The woven Aramid fibers as high strain materials (HSM) are known to improve the through-the-thickness impact strength. However, the addition of the HSM can affect the overall tensile behavior of composite laminates. This study investigates the effect of the woven Aramid fiber on the in-plane tensile behavior of Carbon/ epoxy laminates. Laminates are fabricated using an easy and cost-effective Vacuum Assisted Resin Infusion Molding (VARIM) setup. A uniaxial tensile test was conducted to analyze the tensile behavior of Carbon/Aramid hybrid composites. The effect of adding the woven Aramid layer and the Carbon fabric sequence on the tensile modulus, strain to failure and modulus of toughness are investigated in this study. The results revealed that the presence of Aramid has a positive hybrid effect on the failure strain, exhibiting pseudo-ductile behavior with a compromise in the tensile modulus of the virgin Carbon/epoxy laminate.
INFLUENCE OF CROSSING WEAR ON ROLLING CONTACT FATIGUE DAMAGE OF FROG RAIL
Authors: Kou Lei , Sysyn Mykola , Liu Jianxing
Published: May 2024

The damage of the frog rail significantly affects the wear of the crossing rail and restricts the passing speed of the train. A geometric 3D modeling of the vehicle passing through the crossing center is particularly concerned with the cumulative wheel-rail contact of the traffic volume. The frog rail wear is simulated to obtain the dynamic change of the impact force of the wheel on the frog rail as the rail wears. By summarizing the existing experimental results of other scholars, it is clear that the important factors, that cause the damage of the frog rail, are vehicle load, friction coefficient, slip roll ratio and shear stress.  This paper combines the theoretical analysis of mechanics and 3D simulation to obtain the position change of the wheel-rail contact point with the wear of the frog rail, and finally compares it with the actual measurement results. It can more accurately predict the area where the maximum damage occurs after a certain amount of traffic for a certain fixed model, the change of wheel-rail contact point at frog rail is simulated with the wear of each component. Through theoretical analysis, the main factors determining frog rail damage were determined. Then evaluate the possible damage area of the frog track and control the prediction range to 5-10 cm, which reduces the detection time and cost. The worst state of distraction will be detected in time to facilitate replacement or polishing. Through further research in this area, the service life of the frog rail can be predicted.

Authors: Pathak Ketaki , Ghogale Shital
Published: May 2024

In severe Coronavirus disease 2019 (COVID-19), bloodstream infections (BSIs) are an increasing cause of morbidity and mortality. In critically ill patients with COVID-19, we aimed to evaluate the prevalence, clinical profiles, and outcomes of BSIs. This single-center prospective investigation was conducted at a tertiary care hospital in Western India. All patients (>18 years of age) hospitalized in the intensive care unit (ICU) or ward with RT-PCR-confirmed COVID-19 were included. Demographic information, clinical proficiency, and antibiotic resistance patterns were assessed. Of the 550 patients admitted to the COVID ICU, subsequent BSIs occurred in 7.45% of patients. Gram-negative pathogens comprised a significant proportion of BSIs (53/73, 72.6%). The most frequent isolates were Klebsiella pneumoniae (22/73, 30.1%), Acinetobacter baumannii (11/73,15.06%), and Escherichia coli (7/23, 9.58%). In 57.8% of the cases, multidrug-resistant organisms (MDRO) were discovered. The Enterococcus and K. pneumoniae families comprise the majority of MDRO. Gram-negative bacteria (30.18% [16/53]) were resistant to carbapenems. Increased total leukocyte count, mechanical ventilation, and the presence of comorbidities were significantly associated with the incidence of BSIs. In COVID-19-linked BSIs, we discovered a high frequency of A. baumannii. Clinicians should be aware of potential BSIs in the presence of comorbidities, elevated leukocyte count, and mechanical ventilation. To improve the results, empirical antibiotics must be started promptly, and the situation must be de-escalated quickly. The most frequent isolates were A. baumannii and K. pneumoniae ([11/73, 15.06%] and [22/73, 30.1%], respectively). To reduce the incidence of MDRO, infection control procedures should be strictly followed in patients with multidrug resistance.
Face Recognition and Identification System for Crime Detection Using Python Programming Language
Authors: . Okardi
Published: May 2024

Abstract: Throughout the years, finding criminals has posed a challenging endeavor. In the past, the method relied on leads derived from evidence discovered at the crime scene. Genetic evidence is comparatively straightforward to trace, yet wrongdoers have grown increasingly proficient at obscuring their trail and leaving behind no discernible mark. To address this issue, a face recognition system for crime detection was developed. In this study, a qualitative method was used to collect the face images of criminals in collaboration with law enforcement agencies. An API was built using the criminals National Identification Numbers. Then, a face recognition view that returns the object of the user gotten from the National Identification Number was built. The returned user objects (including face images of the user) underwent preprocessing steps, including normalization, resizing, and noise removal, to enhance the quality and standardize the facial features. Local Binary Patterns algorithm in Python OpenCV library was applied to the preprocessed face images to extract discriminative features from the preprocessed face images. These features aimed to capture the unique characteristics of each face for subsequent recognition. The algorithm was trained on the extracted features and tested given a new input image. The interface component specification of the system was designed using HTML, CSS, and JavaScript client-side technologies.

Published: May 2024

Abstract: This study presents an Arduino-based system for advising users of nearby EV stations and tracking the status of their automobile batteries. The MQ-2 gas sensor, DHT11 temperature sensor, and DC voltage sensor are the three main sensors that the system interfaces with through the use of an Arduino Uno microcontroller as the central controller. When the battery temperature rises over safe limits, the DHT11 sensor monitors it and sends out alarms. By detecting gases being released into the atmosphere, the MQ-2 gas sensor warns customers of possible battery problems. Through the use of a Java web application, the DC voltage sensor suggests local EV stations and notifies users when levels are low. The sensor measures voltage and percentage. By delivering timely alerts and making charging facilities easier to use, this integrated solution raises user awareness of battery health and promotes safer driving. By fusing Arduino technology with sensor data and web application capability, it illustrates how IoT can be used practically in the automotive industry.

Abstract: Here we have the systems of :- 1) Advancements in Vehicle Control :- This summary highlights two recent advancements in vehicle control technology which are the enhanced Handling for Passenger Cars: Researchers have developed a novel control system inspired by expert driver techniques. This system optimizes a car's handling during maneuvers requiring simultaneous acceleration and sharp turns. Simulation testing demonstrates significant performance improvements. Improved Unmanned Ground Vehicle (UGV) Operation on Unstructured Terrain: A new approach addresses the challenges of controlling UGVs on rough terrain. The solution combines sensor fusion for terrain characterization, a neural network for terrain classification, and an adaptive control system for real-time stability adjustments. This multi-pronged approach has been validated through successful experimentation on a UGV platform. 2) Enhancing UGV Control with Haptic Feedback :- A separate study explores the use of haptic feedback to improve UGV control in difficult environments. Traditional operator interfaces often lack sufficient sensory information, leading to reduced situational awareness and operational difficulties. This research proposes a haptic tablet interface that provides the operator with a tactile sense of the UGV's traction state. User studies confirm that this approach significantly reduces the time a UGV spends immobilized due to traction loss. These advancements collectively represent significant progress in vehicle control technology, with potential benefits for both manned and unmanned vehicles operating in challenging scenarios

Objectives: To assess the acute complications and QOL of patients with ischemic stroke at a hospital.
Methods: A descriptive cross-sectional design was used to recruit 131 patients with ischemic stroke at the Shar Hospital in Sulaimaniyah City, Iraq. The non-probability purposive sampling technique was performed at the Neurology Unit. Information was obtained through direct interviews. The questionnaire consists of patients’ characteristics, acute complications, and QOL.
Results: Most patients were aged 60-69 years old (67.25%), males (53.4%), married (90.8%), had no formal education (66.4%), housewives (36.6%), from urban areas (79.4%), had no previous transient ischemic attack (TIA) (76.3%), had two comorbidities (35.1%), had a chest infection (61.8%), UTI (62.6%), urinary retention (59.5%), shoulder pain (63.4%), fever (67.2%), had 7-8 complications (25.2%), had poor QoL for energy dimension (61.8%), family role (57.3%), language (58%), mobility (58.8%), mood (60.3%), self-care (70.2%), vision (73.3%). However, most patients had good QoL for personality (52.7%), social role (64.9%), thinking (60.3%), upper extremity function (50.4%), and work/productivity (55%). Additionally, most patients (66.4%) had poor overall QoL, and only 33.6% had good overall QoL. A significant association (p≤0.05) was found between participants’ QoL and the complication numbers, age, residency, TIA and attack numbers.
Conclusions: Most ischemic stroke patients had poor overall QoL and poor QoL with vision, self-care, energy, and mood.
A generic quantum Wielandt's inequality
Authors: Jia Yifan , Capel Angela
Published: May 2024

Quantum Wielandt's inequality gives an optimal upper bound on the minimal length k such that length-k products of elements in a generating system span Mn(C). It is conjectured that k should be of order O(n2) in general. In this paper, we give an overview of how the question has been studied in the literature so far and its relation to a classical question in linear algebra, namely the length of the algebra Mn(C). We provide a generic version of quantum Wielandt's inequality, which gives the optimal length with probability one. More specifically, we prove based on [KS16] that k generically is of order Θ(log⁡n), as opposed to the general case, in which the best bound to date is O(n2log⁡n). Our result implies a new bound on the primitivity index of a random quantum channel. Furthermore, we shed new light on a long-standing open problem for Projected Entangled Pair State, by concluding that almost any translation-invariant PEPS (in particular, Matrix Product State) with periodic boundary conditions on a grid with side length of order Ω(log⁡n) is the unique ground state of a local Hamiltonian. We observe similar characteristics for matrix Lie algebras and provide numerical results for random Lie-generating systems.
Certifying long-range quantum correlations through routed Bell tests
Authors: Lobo Edwin Peter , Pauwels Jef , Pironio Stefano
Published: May 2024

Losses in the transmission channel, which increase with distance, pose a major obstacle to photonics demonstrations of quantum nonlocality and its applications. Recently, Chaturvedi, Viola, and Pawlowski (CVP) [arXiv:2211.14231] introduced a variation of standard Bell experiments with the goal of extending the range over which quantum nonlocality can be demonstrated. These experiments, which we call `routed Bell experiments', involve two distant parties, Alice and Bob, and allow Bob to route his quantum particle along two possible paths and measure it at two distinct locations – one near and another far from the source. The premise is that a high-quality Bell violation in the short-path should constrain the possible strategies underlying the experiment, thereby weakening the conditions required to detect nonlocal correlations in the long-path. Building on this idea, CVP showed that there are certain quantum correlations in routed Bell experiments such that the outcomes of the remote measurement device cannot be classically predetermined, even when its detection efficiency is arbitrarily low. In this paper, we show that the correlations considered by CVP, though they cannot be classically predetermined, do not require the transmission of quantum systems to the remote measurement device. This leads us to define and formalize the concept of `short-range' and `long-range' quantum correlations in routed Bell experiments. We show that these correlations can be characterized through standard semidefinite-programming hierarchies for non-commutative polynomial optimization. We then explore the conditions under which short-range quantum correlations can be ruled out and long-range quantum nonlocality can be certified in routed Bell experiments. We point out that there exist fundamental lower-bounds on the critical detection efficiency of the distant measurement device, implying that routed Bell experiments cannot demonstrate long-range quantum nonlocality at arbitrarily large distances. However, we do find that routed Bell experiments allow for reducing the detection efficiency threshold necessary to certify long-range quantum correlations. The improvements, though, are significantly smaller than those suggested by CVP's analysis.

O artigo enfoca a performance do Tribunal Popular da Pesca, ocorrido em 14 de janeiro de 2020, no RN, revelando-se como uma importante estratégia regional de mobilização da categoria profissional dos pescadores artesanais nas negociações e práticas de reciprocidade política em torno da luta por direitos na atividade pesqueira afetada pela catástrofe do derramamento de óleo no Nordeste, identificada entre agosto de 2019 e janeiro de 2020, chegando até a costa dos estados do Espírito Santo e Rio de Janeiro no Sudeste do Brasil. A metodologia utilizada foi a observação participante no acompanhamento sistemático prévio ao Evento junto aos grupos de participantes e organizadores, continuando depois da realização deste. O artigo utilizou de revisão documental e bibliográfica da temática, trazendo reflexões analíticas sobre performance, direitos consuetudinários e direitos da legislação, assim como a ausência de justiça na reparação de violações de direitos adquiridos e retirados. Conclui pela eficácia simbólica da performance no que evidencia a injustiça frente à vulnerabilidade das populações pesqueiras tradicionais, se mostrando importante para a organização do litígio judicial posteriormente oficializado contra a União, denunciada por descaso na resposta para conter o óleo e na mitigação impacto deste nas comunidades que vivem do mar e do litoral.
