Combustion characteristics of a lean-burned CBM engine with hydrogen direction injection
Authors: Jia Wei
Published: January 2023

A 3D model of a CBM engine was established, and the combustion modes under different injection parameters and ignition matching conditions were studied by using methane PFI+ hydrogen DI injection method. Flame propagation, flame structure and engine indication thermal efficiency under the three combustion modes were analyzed. The results show that when the interval between injection and ignition is less than 10°CA, the flame structure of plume ignition will be formed; when the interval between injection and ignition is greater than 10°CA and less than 16°CA, the flame form of concentration stratification will be formed; when the interval is greater than 16°CA, the homogeneous flame structure will be formed. The flame propagation speed of plume ignition is significantly higher than that of the other two combustion modes. Under the three combustion modes, the injection and ignition schemes are adjusted several times. When the injection time is -8°CA ATDC and the ignition time is -2°CA ATDC, the flame structure is the plume ignition structure. The indicated thermal efficiency is higher than the other two combustion modes, and the indicated thermal efficiency of the engine is up to 52.8%.

Authors: Garba Bashiru , Dirie Najib Isse
Published: January 2023

Leptospirosis can cause severe disease and probable death in humans. Antigenic epitopes from pathogenic strains of the bacteria have shown potential for serving as vaccine candidates and play a key role in the sensitivity and specificity of immunodiagnostic tests. This in-vitro analysis was undertaken to develop a prototype recombinant DNA vaccine using in-silico epitope prediction method. Epitope prediction software programs predicted the most antigenic linear B-cell epitopes of OmpL1, LipL32, LipL41, Loa22, and LigA. Thirteen epitopes were predicted, connected by the Gly-Ser linker, and synthesized. The purity of the concentrated recombinant multi-epitope protein was assessed by restriction enzyme digestion and gel electrophoresis. In-vitro expression on mammalian Chinese Hamster Ovary cell line indicated strong cytoplasmic fluorescence produced based on an indirect immunofluorescence antibody test. The green color of the cytoplasm indicates successful transcribed and translated DNA as against the blue-stained nucleus observed in the un-transfected control group based on the indirect immunofluorescence antibody test. The findings of the current study showed high antibody binding potentials of the vaccine constructs, which could be used for diagnostic applications or as polyvalent vaccine candidates.

Published: January 2023

Microalgae, especially Amphora coffeaeformis (A. coffeaeformis), are introduced to poultry diets, mainly as a rich source of polyunsaturated fatty acids (PUFAs), α-linolenic acid, eicosapentaenoic (EPA (and docosahexaenoic (DHA). This study aimed to investigate the effect of dietary supplementation of A. coffeaeformis on broiler chickens’ productive performance, physiological status, and immune response. A total of 180 (Ross 508) broiler chickens aged one day were wing banded and randomly divided into three treatments and a control group according to the form of A. coffeaeformis, with 45 chickens each. Each treatment had three replicates (15 chickens for each replicate). Chickens from the three treatments were fed a diet supplemented with A. coffeaeformis algae at levels of 0.15, 0.45, and 0.75% of the diet from the first week to the fifth weeks of age. The obtained results indicated a significant difference in live body weight (LBW), body weight gain (BWG), and growth rate (GR) at the different experimental periods due to the effects of A. coffeaeformis treatments compared to the control group. Chickens fed basal diet and diet with A. coffeaeformis at levels of 0.45%, and 0.75% significantly increased LBW, BWG, and GR% at all intervals (1-3), (3-5), and (1-5) weeks of age compared to A. coffeaeformis algae at levels of 0.15%. Chickens fed a diet supplemented with A. coffeaeformis 0.45% and AC 0.75% recorded higher plasma total protein insignificantly, albumin significantly, at five weeks of age compared to the other A. coffeaeformis treatments and control group. Moreover, the lower levels of plasma triglycerides, total cholesterol, LDL, and significantly higher levels of plasma HDL were found at a basal diet supplemented by A. coffeaeformis 0.15% and the control group. Also, AC 0.15% and A. coffeaeformis 0.45% recorded insignificantly lower plasma levels of Glutathione and Superproxedase (58.55 and 71.43 mg/l, respectively) when compared with other A. coffeaeformis treatments and control group. Dietary supplementation of chickens’ feed with A. coffeaeformis microalgae can promote the proliferation of beneficial bacteria (microbiota).

Published: January 2023

In vitro production of Bali cattle embryos still needs in-depth investigations to produce embryos suitable for transfer. The current study aimed to examine the level of cell apoptosis in Bali cattle embryos produced in vitro and at three stage of oocyte maturation, fertilization, and embryo culture. A total of 107 pairs of ovaries derived from slaughterhouses of Indonesia were collected. The used oocytes were grades A and B (Grade A had compact cumulus oocyte complex (COC) cells surrounded by five or more layers of cumulus cells, and grade B had a non-compact COC and a dark cytoplasm with complements from the complete radiata corona but surrounded by no more than five layers of cumulus cells). Fertilization of oocytes was done using the semen of a Bali bull. Bali cattle semen was frozen in straw semen for 5 minutes at 1500 rpm twice, then the supernatant and spermatozoa were separated and equilibrated for 30 minutes. Fertilization lasted for 5-6 hours in the incubator. Then, oocyte culture was carried out using CR1aa media and evaluated at 48 hours post-insemination (hpi). The result of the current study showed that the development of Bali cattle embryos produced in vitro after 48 hours of culture included 2 cells (31.91%), 4 cells (32.97%), 8 cells (24.46%), and 16 cells (10.63%). The percentage of embryos containing at least one nucleus exhibiting Terminal dUTP nick-end labeling (TUNEL) characteristics of apoptosis entailed 28.33% (2 cells), 41.93% (4 cells), 43.48% (8 cells), and 50% (16 cells). The division ability of embryos aged 48 hpi consisted of 2, 4, 8, and 16 cells. In conclusion, apoptosis in Bali cattle began to be detected in the two-cells stage. The sooner a cell undergoes apoptosis, the lower the level of the cell’s ability to develop further.

Student-Teacher Email Requests: Comparative Analysis of Politeness Strategies Used by Malaysian and Filipino University Students
Authors: AlAfnan Mohammad Awad , Cruz-Rudio Lourdes dela
Published: January 2023

This comparative study investigates politeness strategies used in Malaysian and Filipino student-teacher requesting emails. After analyzing a corpus of 40 student-teacher email requests that are written by Malaysian and Filipino university students, it is found that Malaysian university students use more direct (i.e., imperative, interrogative) requesting politeness strategies than their Filipino counterparts while Filipino university students use more indirect (i.e., positive, negative) requesting politeness strategies than their Malaysian counterparts. It is also revealed that Filipino students realize their requests longer with more strategies than Malaysian students as they produced more politeness moves than their Malaysian counterparts. This implies that while Filipino students tend to give more reasons and employ other strategies to justify their requests and appeal to their teachers, Malaysian students tend to directly, but politely using politeness mitigation markers, express the request. This study also shows that the use of negative politeness strategies is prominent among Malaysian and Filipino students; however, students also used positive politeness to establish solidarity with teachers with their offering of explanation and expression of goodwill. Although the findings of this study support the universality of request and politeness strategies, differences between the two groups of students are also proof of the culture-specificity of certain strategies. It is recommended to incorporate cross-cultural pragmatic awareness in language classrooms to encourage students to be more culturally adaptable as they engage in communication with people from different nationalities.

Published: January 2023

Apresentar-se-á uma reflexão a partir da experiência teórico-prática advinda dos Estágios Curriculares em Serviço Social, realizados no âmbito da política de saúde no período de 2019 a 2020. Salienta-se o projeto de intervenção voltado à execução da Educação Permanente em Saúde à equipe de trabalhadores da Rede de Atenção Psicossocial de Canoas, no Rio Grande do Sul. Entende-se a Educação Permanente em Saúde como uma estratégia metodológica para se refletir e avaliar a implantação e implementação da Política de Saúde Mental nos dias atuais, pois representa um importante meio de resistência perante os retrocessos enfrentados nos últimos anos. Os principais resultados evidenciados foram a reafirmação da dimensão política dos trabalhadores da saúde mental, a criticidade deles sobre a desassistência, subfinanciamento e invisibilidade da saúde mental que impacta uma parcela crescente da população usuária do SUS, em especial, durante a pandemia (2019-2020) da covid-19.
Questão Indígena e Ditadura Cívico-Militar (1964-1985) no Brasil.
Authors: Corne Julia de Souza , Da Silva José Fernando Siqueira
Published: January 2023

A ditadura cívico-militar brasileira (1964-1985), sob a prerrogativa de avanço econômico e contenção das tendencias socialistas, desempenhou ações de despolitização, medo, tortura e repressão contra diversas categorias da população nacional, incluindo os povos indígenas. Expurgados de suas terras, mortos, torturados ou até mesmo incorporados forçadamente a guarda nacional, os indígenas foram vitimas das atrocidades causadas pelo governo militar. Porém, assim como em toda a sua história, os povos indígenas não são agentes passivos nesse processo, mas sim protagonistas e é durante o período ditatorial que o movimento indígena cresce e se desenvolve como força política, dispensando a tutela até então submetida a eles. O Serviço Social, como profissão, considerando sua versão mais progressista orientada pela direção social estratégia dos anos 1990 (conhecida como Projeto ético-Político Profissional), alinha-se com a defesa dos direitos humanos e as demandas da ampla e diversa classe trabalhadora. Deve, por isso, incluir em seus debates a discussão sobre a questão indígena, ainda pouco abordada pela área.

Published: January 2023

A pessoa surda sempre enfrentou dificuldades ao longo do tempo em relação à comunicação com os ouvintes e essas barreiras comunicacionais ainda persistem na atualidade. Mesmo após a conquista dos direitos dos surdos de acesso às políticas públicas com a Constituição Federal de 1988 e as regulamentações sobre acessibilidade, foi possível observar, por meio de um levantamento bibliográfico sobre o assunto, que para uma sociedade acessível, ainda é necessário um longo caminho a ser percorrido. Sabendo disso, apresenta-se uma pesquisa em âmbito local realizada no final de 2018, que foram entrevistados 20 surdos e profissionais de alguns serviços das políticas de assistência social e saúde. O objetivo da pesquisa foi identificar as dificuldades enfrentadas pelos surdos nos atendimentos das políticas sociais e espaços públicos. E que neste artigo, o enfoque foi ao acesso nos serviços de saúde, devido à fala recorrente nas entrevistas desses espaços. A partir das entrevistas concluiu-se que no município de Londrina, os surdos possuem dificuldade de acesso às políticas sociais, em especial aos serviços de saúde, que é uma realidade semelhante com as outras cidades brasileiras. Também que os profissionais das políticas públicas não estão preparados para o acolhimento à pessoa surda devido a uma deficitária formação acadêmica e pouca possibilidade de aperfeiçoamento no ambiente de trabalho. Assim, concluiu-se também que há necessidade de aprofundar as pesquisas nessa temática, mas no sentido de identificar as consequências na saúde dos surdos desse acesso precário a essa política pública.

Published: January 2023

A produção do conhecimento sobre a medida socioeducativa de internação revela-se necessária, na medida em que evidencia esforços, dificuldades e avanços na busca de garantia de direitos fundamentais de crianças e adolescentes.  Partiu-se neste artigo da análise dessa produção, no âmbito das universidades do estado do Paraná e, particularmente, as vinculadas às dissertações de mestrado e teses de doutorado, produzidas a partir do ano de 2012.  A delimitação desta data deve-se à Lei Federal 12.594/2012, que cria o Sistema Nacional de Atendimento Socioeducativo – SINASE e que lança luz à novas estratégias de gestão e novo direcionamento do trabalho nas instituições criadas para viabilizar as medidas de internação. Objetiva-se, no artigo, evidenciar o foco e a importância da produção do conhecimento sobre tais medidas a partir deste marco legal. A pesquisa é de caráter quantiqualitativo e cunho descritivo-exploratório; foi construída através de uma revisão bibliográfica sistemática dessas teses e dissertações. Os resultados indicam duas perspectivas na produção: uma voltada à realidade e para o perfil dos adolescentes em conflito com a lei e a outra direcionada à própria medida socioeducativa de internação e ao trabalho profissional desenvolvido nos CENSEs.

Authors: Hassan Farooq , Amjed Ismail Muhammad , Khan Niazi Madiha
Published: January 2023

Monkeypox is a rare zoonotic disease that is caused by the monkeypox virus, a member of the Poxviridae family. Avoid close contact with animals, whether they are living or dead, especially in endemic areas where this could be a source of infection transmission to healthy people. Separate sick people from those who might be contaminated. Frontline medical staff should be instructed and trained to rigorously adhere to traditional safety practices when dealing with verified or suspected cases. At the nation's entry and exit points, vaccination booths should be placed in order to stop the global spread of this contagious disease. Through extensive public awareness initiatives, people should be informed about sickness prevention, risk factors, and treatments. The public health departments of every nation should be alert for any signs that someone may be suffering from an unusual rash.

Singhari Sperata sarwari is an Indus catfish (family Bagridae) present in Pakistan and Indus drainage system in India. Objective: To check the Prevalence of ectoparasites on Singhari (Sperata sarwari) fish. Methods: A sample of 30 specimens of a freshwater catfish, Sperata sarwari was collected from different areas of Lahore, Pakistan, during December 2017 to May 2018. Total 30 fish were examined for ectoparasites. Out of 30 fish, only 08 were diseased with Lernaea. Results: The total prevalence of Lernaea was 26.66%. Lernaea had highest prevalence (37.5%) in 1000-1200g body weight of fish group, while it was lowest (16.66%) in 100-300g body weight fish group. Lernaea showed highest prevalence (33.33%) in fish length group of 66-85cm, while the least prevalence (14.28%) existed in 25-45cm fish length group. It was also observed that Lernaea showed seasonal variations and it was maximum in winter, (33.33%) in January and minimum in spring and summer (20%) in March and (0%) in April. Conclusions: The results indicated that Singhari fish with more weight and long length had more prevalence of infection as compared to less weight and shorter length. This could be due to access of greater area available to parasites for anchoring and hiding on the large sized fish.

Published: January 2023

Objective: The objective of this investigation was to determine the effects of dexamethasone (DEX) on the weight and cellularity of abdominal and subcutaneous fat depots.
Materials and Methods: The study was conducted on four broiler chicks (20 chicks per group) fed commercial feed and water ad libitum. The DEX was supplied with feed at 0 mg/kg (non-DEX), 3 mg/kg (DEX-1), 5 mg/kg (DEX-2), and 7 mg/kg (DEX-3) from day 0 to day 28. The entire abdominal and subcutaneous fat depots were collected and weighed after sacrificing five birds from each group on days 14 and 28.
Results: The DEX groups had considerably lower (p < 0.05) fat depot weights with dose-related variation noted among the DEX groups. The histological findings revealed the presence of uniloc¬ular, round to oval-shaped adipocytes. The DEX-1 and DEX-2 had way lower (p < 0.05) numbers of adipocytes while the DEX-3 had considerably higher (p < 0.05) numbers of adipocytes than the non-DEX. DEX-1 and DEX-2 had larger (p < 0.05) adipocytes whereas DEX-3 had smaller adipocytes than the non-DEX. Adipocyte sizes and fat depot weights were found to have very strong negative relationships.
Conclusion: Dietary DEX affects the growth and distribution of abdominal and subcutaneous fat depots and adipocyte cellularity subjected to both dose and duration of DEX treatment.

Published: January 2023

Objective: Melilotus officinalis is a plant that grows naturally in northwestern Morocco and could become a promising alternative. The study was carried out to investigate the effects of M. officinalis hay on growth performance, carcass characteristics, and meat quality of goat kids in northern Morocco compared to Medicago sativa.
Materials and Methods: Eighteen 3-month-old male “Beni Arouss” goat kids have been divided similarly into two groups. The control group (Luc) received lucerne hay, and the test group (YSClov) received yellow sweetclover hay, both supplemented with concentrate. Average daily gain and dry matter intake were determined during the experiment. After 99 days, goat kids were weighed, and carcass characteristics were determined. Meat quality was evaluated using samples from the semimembranosus (SM) and longissimus thoracis muscles.
Results: The addition of YSClov significantly increased ash content (p < 0.001) and fat content (p < 0.01), reduced water holding capacity (p < 0.01), and SM pH 24 (p < 0.05). The YSClov meat was significantly more tender than the Luc meat, with corresponding values of 8.20 and 11.80 kg/ cm² (p < 0.05), while the Luc meat was more tender when cooked. No significant effect was found for the other parameters. The YSClov meat is richer in desirable fatty acids (DFA), while the Luc meat appears to be richer in omega-3 DFA(p < 0.01).
Conclusion: Melilotus officinalis hay showed promising results in intramuscular fat, protein content, tenderness, DFA content, and similar growth performance compared to conventional feeds.

Published: January 2023

Indigenous sheep are highly adaptable and widely distributed in different regions of Bangladesh. They are famous for their tolerance to harsh environmental conditions, low demand for feed, and disease resistance with minimum or no housing and management facilities. Ample indiscrimi¬nate research reports and case studies on the native sheep of Bangladesh have been published. Nonetheless, a comprehensive review of reproductive and productive performances, as well as their various morphometric physiognomies and climate resilience capabilities, is lacking. This review was designed to explore and summarize the available research reports on indigenous sheep to highlight the gaps and provide an updated database for the future research plan for sustainable native sheep production in Bangladesh. It covers studies on sheep biodiversity, their adaptabil¬ity to the local environment, morphometric features, feeding and nutrition, reproduction and production performances, diseases and health management, and the problems and prospects of sheep farming in Bangladesh. Due to the increased demand for animal protein, especially red meat, the scope of sheep farming increases along with that of other large and small ruminants. The vital constraints of sheep production in Bangladesh include insufficient feed and fodder sup¬ply with its high prices, higher disease occurrence with low or no management practices, kid mortality, and a poor marketing channel with the lower popularity of sheep meat than goat meat. Future research would be a prerequisite to measuring the impact of native sheep on household economies and food security during the year, evaluating the other challenges, and finding out the possible interventions in the fields of nutrition, reproduction, and health management.

Objective: The objectives of this research are to overcome the limitations of rice bran (RB) and de-oiled rice bran (DORB) by fermentation anaerobically using inoculum from the rumen of a canulated sheep for desirable chemical changes.
Materials and Methods: Initially, RB and DORB were fermented by 10% rumen liquor for 12 h at 39°C at different moisture levels (10, 20, 30, 40, 50, and 60% phosphate buffer). Again, DORB was fermented for 24, 48, and 72 h at 39°C using 10% rumen liquor at different moisture levels (10, 20, 30, 40, 50, and 60% phosphate buffer). Before and after fermentation, RB and DORB were analyzed for pH, proximate components, neutral detergent fiber (NDF), total-P, inorganic-P, and phytate-P.
Results: Fermentation of RB and DORB for 12 h reduced (p < 0.05) pH, crude fiber (CF),NDF, and phytate-P, but increased (p < 0.05) the content of inorganic-P. Subsequent fermentation of DORB for 24, 48, and 72 h reduced pH, CF, and NDF. Total-P of fermented DORB remained similar till 72 h fermentation (p < 0.05). But, inorganic-P increased with the increasing duration (24, 48, and 72 h) of fermentation and increased (30, 40, and 50) moisture level (p < 0.05). Alternatively, phytate-P decreased with increasing duration and moisture level (p < 0.05).
Conclusion: Inoculation of rumen microbes and incubation of RB (12 h) and DORB (24 h) at room temperature reduced phytate-P and fiber content (CF and NDF) when the moisture level was up to 50%; those are the indicators to reduce the limitation of RB and DORB to use as feed for non-ruminant animals like poultry and pigs.

Published: January 2023

Background: The COVID-19 pandemic, originating in China in December 2019, spread throughout the world like wildfire in a matter of months. With the health-care resources being reallocated toward the management of the patients found to be suffering from the severe acute respiratory syndrome coronavirus 2 infection, the routine health-care services in all walks of medicine have faced the fire.

Aim and Objectives: This study was undertaken with the aim to compute the brunt suffered by the everyday services at the dermatology department of a tertiary care hospital at the behest of the pandemic.

Materials and Methods: This was an observational study carried out retrospectively, wherein the hospital records of the patients visiting the outpatient, procedural, and inpatient dermatology department at a tertiary care center in North India were analyzed from June 2019 to May 2021.

Results: A significant decrease of 51.33%, 75.53%, and 58.42% was found in the number of patients visiting the outpatient, procedural, and inpatient dermatology department, respectively, in June 2020–May 2021 as compared to June 2019–May 2020.

Conclusions: Our study reveals that the regular services of the dermatology department were severely affected by the pandemic. We feel that it is safe to say that this observation holds true for the routine services offered by all the departments all over the world. Learning and adapting to the changing patterns of patient care needs and the redistribution of health-care resources is of paramount importance as the end of this pandemic is not yet visible in the foreseeable future and also to be ready for any other such calamities that the world might face in the upcoming times.

In order to use the four-probe method to determine the resistivity of a coating of high-entropy alloys, the correction functions were calculated when determining the resistivity based on measuring the potential difference between the probes placed on a hexagonal stainless steel sample coated with a conductive coating. The presence of boundaries with a non-conductive medium (air) and the presence of a conductive substrate with a conductive coating were taken into account. The method of mirror images was used for the calculation. Correction functions for a hexagonal sample with a thin coating are obtained.

The article discusses the features and development of poultry farming in the Republic of Kazakhstan. Various points of view of domestic and foreign scientists and researchers on the issue of the specifics and further development of this industry in the country and in the region are analyzed. For analysis, the authors selected such indicators as the number of poultry, the production of poultry meat, the production of eggs, the consumption rate per capita: eggs, meat and meat products, the price of products. On the basis of statistical data, the state of poultry farming in the Republic of Kazakhstan and the North Kazakhstan region over the past 5 years was analyzed. Wh en writing the article, the authors took data from poultry enterprises in the North Kazakhstan region for 2017 -2021, namely, the share of egg production by poultry farms in the region, total per capita consumption and the average price per year of poultry products were calculated in detail. As a result, there is a strong demand for poultry products in the country's market, so poultry farms will need to find all opportunities to increase the volume of production and increase its competitiveness.
Evolution of Brain Networks
Authors:   , Ardesch Dirk Jan
Published: January 2023

The brain is an intricate organ responsible for dealing with our thoughts, feelings, and
behaviors. The human brain tripled in size during recent evolution, while the rest of
our body stayed more or less the same size. This remarkable change has inspired brain
researchers to investigate why such brain expansion took place, and how it affects the way
our brain works. In this thesis, we investigated the organization of the brain’s wiring by
looking at the connections between each part of the brain and how they form a complex
network — the connectome.

We compared the human connectome to that of other primate species, including chimpanzees, gorillas, rhesus monkeys, and capuchin monkeys. We found that all these
connectomes have important aspects in common: They are wired in an efficient way
and contain ‘shortcuts’ between important brain regions for quick communication of
information. At the same time, they show subtle differences in their wiring organization
that are closely linked with their brain size. For example, larger brains have relatively less
long-range connections, likely because long connections take up more and more space
in larger brains. Larger brains also show more specialization of connectivity, especially
between the left and right sides of the brain.

The findings of this thesis help our understanding of human brain evolution by showing
the relationships between brain size and connectome organization in a wide range
of monkeys and apes. Our work suggests that primate brains are wired according to
a shared connectome blueprint, with key aspects of connectome organization found
in all the studied species. Brain size and adaptations to specific environments form the
variations on this conserved blueprint. In the case of humans, our big brains may have
paved the way for extensive specialization of brain connectivity, leading to specialized
brain functions such as language and highly developed cognition.

Published: January 2023

The existing oil waste water contains oil, solids, water and heavy metals. This oil waste is a contaminant material that can cause negative impacts to the aquatic environment as well as the existing living creatures around it so that it requires a careful and fast handling to clean. The research resulted in the tracking system on the image-based-ship robot by using the method of   histogram and fuzzy logic controller that can detect the image of waste water well. The result of the testing of the ship robot done on the pool indicated   that it took about ± 196.92 seconds for the robot to detect the image of oil waste objects. The oil waste suctioning process took a maximum of 60 seconds for once.
A CONSTITUCIONALIDADE DAS ORDENS JUDICIAIS DE QUEBRA DE SIGILO TELEMÁTICOS, DE UM CONJUNTO NÃO IDENTIFICADO DE PESSOAS, POR GEOLOCALIZAÇÃO À LUZ DOS DIREITOS À PRIVACIDADE DE INTIMIDADE
Authors: Sakamoto Maria Laura Grisi
Published: January 2023

A constitucionalidade das ordens judiciais de quebra de sigilo de dados telemáticos de um conjunto não identificado de pessoas, por geolocalização, tem sido alvo de grandes discussões na sociedade jurídica. A ordem genérica de tratamento de dados pessoais e afastamento do direito de privacidade e do sigilo de dados de um número desconhecido de pessoas, não preenche nenhum requisito inerente ao princípio da proporcionalidade, como parâmetro para se aferir a validade de restrição a direitos fundamentais. A pretensão de quebrar o sigilo telemático sem a identificação de alvos específicos, baseada na varredura genérica de geolocalização de pessoas, na contramão das balizas normativas existentes, é manifestamente inconstitucional e ilegal. Desvia a lógica subjacente ao direito processual penal brasileiro e a todo Estado democrático de direito ao determinar que sejam produzidos elementos de prova sobre um sem-número de pessoas, para só posteriormente determinar sobre quem repousa suspeita. O presente trabalho pretende expor a inconstitucionalidade e a ilegalidade dessas decisões, analisando, ainda, a postura do Supremo Tribunal Federal.
