Published: June 2021

Vehicle re-identification (Re-ID) aims to solve the problem of matching and identifying the same vehicles under the scene of cross multiple surveillance cameras. Finding the target vehicle quickly and accurately in the massive vehicle database is extremely important for public security, traffic surveillance and applications on smart city. However, it is very challenging due to the orientation variations, illumination changes, occlusion, low resolution, rapid vehicle movement, and amounts of similar vehicle models. In order to overcome these problems and improve the accuracy of vehicle re-identification, a multi-branches network is proposed, which is integrated by global-local feature fusion, channel attention mechanism, and weighted local feature. First, the fusion of global and local features is to obtain more complete information of the vehicle and enhance the learning ability of the model; second, the purpose of embedding the channel attention module in the feature extraction branch is to extract the personalized feature of the vehicle; finally, the influence of sky area and noise information on feature extraction is weakened by weighted local feature. The comprehensive experiments implemented on the mainstream evaluation datasets including VeRi-776, VRIC, and VehicleID indicate that our method can effectively improve the accuracy of vehicle re-identification and is superior to the state-of-the-art methods.

Background:Patients with stage II to III breast cancer have a high recurrence rate. The early detection of recurrent breast cancer remains a major unmet need. Circulating tumor DNA (ctDNA) has been shown to be a marker to detect disease progression in metastatic breast cancer. We aimed to evaluate the prognostic value of ctDNA in the setting of neoadjuvant therapy (NAT).Methods:Plasma was sampled at the initial diagnosis (defined as before NAT) and after NAT and breast surgery (defined as after NAT). We extracted ctDNA from the plasma and performed deep sequencing of a target gene panel. The detection of alterations, such as mutations and copy number variations, were considered to indicate ctDNA positivity.Results:A total of 95 patients were enrolled in this study; 60 patients exhibited ctDNA positivity before NAT, and 31 patients had ctDNA positivity after NAT. A pathologic complete response (pCR) was observed in 13 patients, including one ER(+)Her2(-) patient, six Her2(+) patients and six triple-negative breast cancer (TNBC) patients. Among the entire cohort, multivariate analysis showed that an N3 classification and ctDNA positivity after NAT were independent risk factors that predicted recurrence (N3, hazard ratio (HR) 3.34, 95% confidence interval (CI) 1.26 – 8.87, p = 0.016; ctDNA, HR 4.29, 95% CI 2.06 – 8.92, p < 0.0001). The presence of ctDNA before NAT did not affect the rate of recurrence-free survival. For patients with Her2(+) or TNBC, non-pCR breast cancer patients were associated with a trend of higher recurrence (p = 0.105). Advanced nodal status and ctDNA positivity after NAT were significant risk factors for recurrence (N2 – 3, HR 3.753, 95% CI 1.146 – 12.297, p = 0.029; ctDNA, HR 3.123, 95% CI 1.139 – 8.564, p = 0.027). Two patients who achieved a pCR had ctDNA positivity after NAT; one TNBC patient had hepatic metastases six months after surgery, and one Her2(+) breast cancer patient had brain metastasis 13 months after surgery.Conclusions:This study suggested that the presence of ctDNA after NAT is a robust marker for predicting relapse in stage II to III breast cancer patients.
Stewardship and administrative capacity in green public procurement in the Czech Republic: evidence from a large-N survey
Authors: Plaček Michal , Valentinov Vladislav , Campo Cristina del , Vaceková Gabriela , Ochrana František , Šumpiková Markéta
Published: June 2021

Background
The uptake of green public procurement in the Czech Republic is known to lag behind the European standards. We trace this condition back to the adverse effects of a specific type of decision-making tradeoff faced by the Czech public procurement officials, namely the tradeoff between stewardship and administrative compliance. The tradeoff means that public procurers are aware of, and seek to forestall, administrative risks and complications attendant on the conscientious non-perfunctory implementation of green public procurement.
Results
The overall result is that public procurers ultimately come to prioritize the contract criterion of the lowest price over ecological criteria. The existence of the tradeoff has been generally confirmed by the results of a unique large-N survey of more than 1,100 respondents from a group of local public officials and mayors in the Czech Republic.
Conclusion
We have found that the decision-making of Czech public procurers is affected by the tradeoff between stewardship and administrative compliance, which turn out to be mutually conflicting goals. On the one hand, many public procurers do possess stewardship motivation that shapes their positive attitude to GPP. On the other, they are painfully aware of, and seek to forestall, administrative risks and complications attendant on the conscientious, i.e., non-perfunctory, implementation of GPP.

Coupled with the outbreak of Covid-19 in Nigeria, there has been a controversial trailing of the Covid-19 incidence in Kogi State involving the state authorities and the Nigeria Centre for Disease Control (NCDC). Giving the importance of appropriate awareness and the perceptions to curbing the spread of the disease, this study aimed at assessing the knowledge, perception and precautionary measures of Kogi state residents in response to the outbreak of Covid-19. An online cross-sectional survey was conducted among 401 residents in Kogi State Nigeria, with a structured questionnaire. Data collected were analyzed using descriptive statistics of frequencies and Simple percentage in tables. Findings revealed that all the participants were aware of and had basic knowledge about Covid-19. The study participants had ample knowledge about the required preventive measures and how to protect themselves from Covid-19. It was also revealed that 45.2% of the respondents were conversant with the practice of three to more of the precautionary guidelines for preventing Covid-19. The study also found that a significant number of the respondents held a very low risk perception of Covid-19 by expressing an unlikely probability of getting infected by the virus. As regards skepticism and belief on coronavirus, 45.9% believed that Covid-19 is a hoax which was invented by interest groups for financial gains; 46.1% opined that the number of people reported by the NCDC as infected by the coronavirus in Nigeria is exaggerated. Again, 33.7% of the respondents believed that the second wave of the Covid-19 in Nigeria was a scam. The main source of Covid-19 information utilized by majority of the respondents was from Television programmes (34.2%) and Whatsapp (31.9%) platforms. The study concluded that while there was a high level of awareness of Covid-19 among residents of Kogi State and a remarkable level of precautionary practices against the spread of the Covid-19 virus, there are however, indications of misconceptions and misinformation that breeds skepticism and belief that may be detrimental to curbing effectively, the spread of the Covid-19 virus within the state

Authors: A AKHILA NAZ K , Jeena R S , Niyas P
Published: June 2021

An arrhythmia is a condition which represents irregular beating of the heart, beating of the heart too fast, too slow, or too early compared to a normal heartbeat. Diagnosis of various cardiac conditions can be done by the proper analysis, detection, and classification of life-threatening arrhythmia. Computer aided automatic detection can provide accurate and fast results when compared with manual processing. This paper proposes a reliable and novel arrhythmia classification approach using deep learning. A Deep Neural Network (DNN) with three hidden layers has been developed for arrhythmia classification using MIT-BIH arrhythmia database. The network classifies the input ECG signals into six groups: normal heartbeat and five arrhythmia classes. The proposed model was found to be very promising with an accuracy of 99.45 percent. The real time signal classification and the application of internet of things (IOT) are the other highlights of the work.

Published: June 2021

In this study, a cancer eradication model involving effector cells in the presence of gene therapy, immunotherapy, and chemotherapy has been proposed. Boundedness and positiveness of the solutions in the respective feasible domains of the proposed model are verified. Conditions for which the equilibrium points of the system are stable have been derived. Amounts of immunotherapy to be injected to a patient for eradication of cancerous tumor cells have been found. To minimize the chemotherapy drug-induced toxicity to the patient, an optimal control problem for the system has been constructed and solved. Numerical and graphical results have been presented. Through the investigation, it was seen that tumor cells can be eliminated in a specific time interval with the control of chemotherapeutic drug concentration.

Published: June 2021

Методами потенциометрического титрования, ИК-спектроскопии, твердофазной ЯМР-спектроскопии 13С и химического анализа исследовано
гелеобразование технических лигнинов (окисленного гидролизного, сульфатного, натронного и лигносульфонатов) и лигнина Пеппера при взаимодействии с солями металлов: CaCl2, Mg(NO3)2,FeSO4, Co(NO3)2, Pb(NO3)2, Fe(NO3)3, CuSO4, AgNO3. Установлено, что способностью к гелеобразованию обладают соединения, представляющие собой соли слабого основания и сильной кислоты; катион металла имеет стандартный потенциал выше определенного значения, обладает умеренной способностью к гидролизу, а гидроксид катиона, образующийся в реакции гидролиза, имеет относительно низкую растворимость. При формировании геля образуется соединение состава R–COO–Mez+–OOC–R z = 2,3. Предложена схема межмолекулярных связей в точке образования гидрогеля лигнина, в соответствии с которой смежные молекулы лигнина связываются между собой тремя типами связей: ионной между карбоксильными группами лигнина и катионами металла, координационной между катионами металла и молекулами воды, входящими в координационную сферу; и водородными, связывающими все компоненты системы в единое целое. Гидрогели лигнина обладают высокой сорбционной способностью по отношению к тяжелым металлам, таким как свинец, железо и медь, составляющей в зависимости от содержания кислых групп в лигнине и молярной массы сорбата ~ 25–50% от массы лигнина. Это открывает возможность использовать новый вид гидрогелей лигнина для очистки сточных вод химических предприятий.

Potentiometric titration, IR-spectroscopy of 13C solid-state NMR spectroscopy, and chemical analysis were used to study the gelation of technical lignins (oxidized hydrolysis, Kraft, sodium, and lignosulfonates) and Pepper lignin in interaction with metal salts: CaCl2, Mg(NO3)2,FeSO4, Co(NO3)2, Pb(NO3)2, Fe(NO3)3, CuSO4, AgNO3. It has been established that compounds that are salts of a weak base and a strong acid have the ability to gelation; the metal cation has a standard potential above a certain value, has moderate hydrolysis ability, and the cation hydroxide formed in the hydrolysis reaction has a relatively low solubility. During gel formation, a compound of the composition R–COO–Mez+–OOC–R z = 2,3 is formed. A scheme of intermolecular bonds at the point of lignin hydrogel formation is proposed, according to which adjacent lignin molecules bind to each other by three types of bonds: ionic between carboxyl groups of lignin and metal cations, coordination between metal cations and water molecules included in the coordination sphere, and hydrogen connecting all the components of the system into a single whole. Lignin hydrogels have a high sorption ability with respect to heavy metals such as lead, iron and copper, which, depending on the content of acid groups in lignin and the molar mass of the sorbate, is ~ 25–50% by weight of lignin. This opens up the possibility of using a new type of lignin hydrogels for wastewater treatment of chemical plants.
Implementation of groundwater protection measures, particularly resource-directed measures in South Africa: a review paper
Authors: Pienaar H. , Xu Y. , Braune E. , Cao J. , Dzikiti S. , Jovanovic N. Z.
Published: June 2021

This review paper on groundwater protection measures in South Africa focuses on the actual implementation of groundwater protection measures, in particular, the resource-directed measures (RDM) as described in Chapter 3 of the National Water Act (NWA). Significant catchment-wide implementation of RDM has taken place in a phased manner throughout various catchments since 2012. By 2015, approximately R380 million had been expended on the catchment-wide implementation of the water resource protection measures over a period of 15 years. Considerable effort went into refining the RDM methodology, taking into account the groundwater component of the overall resource. In this paper, we contend that RDM, in its present form, will not make a significant contribution to groundwater resource protection and security in the country. This is a major concern because the Groundwater Strategy of the Department of Human Settlements, Water and Sanitation (DHSWS) had declared the protection of groundwater as a national priority. This paper also examines institutional and governance arrangements (or lack thereof) as well as providing recommendations to support the effective implementation of groundwater protection provisions as prescribed by South Africa's water legislation.

Authors: MI Abd El-Ghany , Abdallah Nahed , Eldars Waleed
Published: June 2021

Background:

Type 2 diabetes is a part of metabolic syndrome associated with a higher
risk of vascular complications. Diabetes is characterized by changes in platelet morphology, function,
and platelet hyperactivity so, it's considered a prothrombotic condition. Morbidity and mortality
in people with type 2 diabetes-related to micro and macrovascular complications. Novel biomarkers
are needed to identify and treat people at higher risk.

Objective:

The main objective of this controlled cross-sectional study was to evaluate Platelet volume
indices (PVI) in subjects with type 2 diabetes with and without complications in comparison
to subjects without diabetes.

Methods:

Hundred and thirty-five subjects aged from 35 to 60 years were subdivided into 3
groups. Group A includes 55 subjects with type 2 diabetes with complications. Group B includes
45 subjects with type 2 diabetes without complications. Group C includes 35 normal healthy subjects.
Detailed clinical history was taken. Also, PVI, fasting blood glucose (FBG), hemoglobin
A1c, and creatinine were obtained.

Results:

Mean Platelet Volume (MPV), Platelet Distribution Width (PDW), Plateletcrit (PCT), and
Platelet large cell ratio (P-LCR) were significantly higher among subjects with retinopathy, nephropathy,
and neuropathy than other subjects with diabetes who didn't develop complications
(P<0.001). At cutoff value > 11.9 fL, MPV have diagnostic sensitivity 80% and specificity 97.8%.
Whereas PDW >16.9fL has a sensitivity of 74.5% and specificity of 100% for diabetic microvascular
complications (retinopathy, nephropathy, and neuropathy).

Conclusion:

MPV and PDW may be considered as possible biomarkers for the early detection of
diabetic microvascular complications.
Intracranial Cisternal Lipoma Associated with Cerebellar Cortical Dysplasia Diagnosed Using Dixon Technique: A Case Report and a Review of Literature
Authors: Hwang Minhee , Park Hyun , Baek Hye Jin , Ryu Kyeong Hwa , Cho Eun , Yoon Seokho
Published: June 2021

Background:

Intracranial lipomas are very rare congenital malformations. Previous
studies have shown various brain anomalies related to intracranial lipomas, most of which are agenesis
or dysgenesis of the adjacent structures. To the best of our knowledge, cortical dysplasia related
to intracranial lipoma has yet to be reported.

Case Report:

We present a rare case of intracranial lipoma in the quadrigeminal and superior cerebellar
cisterns with combined cerebellar cortical dysplasia. A 43-year-old female underwent brain
MRI to identify possible cause of headache. We made a confident diagnosis based on MR findings
using Dixon technique, which is a fat-water separation method based on chemical shift. We also
identified unique combined abnormalities of the right cerebellar hemisphere near the cisternal lipoma
that showed an abnormal vertical orientation of the cerebellar folia and disorganized parenchymal
pattern.

Conclusion:

This case exhibits the rareness of the intracranial lipoma related cerebellar cortical
dysplasia by reviewing relevant literature and also highlights the usefulness of Dixon techniques in
daily clinical practice.

Published: June 2021

Early diagnosis and accurate prognosis are significant important challenges against effective treatment of
cancer and improving patient’s condition. Hitherto, many research works have tended to focus on the carcinoembryonic
antigen (CEA) to detect cancers and estimate the survival rates of patients with multiple cancer types, including
colorectal, breast, non-small cell lung, and pancreas cancer. Limited sensitivity and specificity of this traditional tumor
marker make it an inappropriate biomarker to diagnose cancer, especially in the early stages while several lines of
research have introduced miRNAs as reliable indicators of tumor initiation, development, and therapy response. Indeed,
miRNAs have unique properties that provide considerable benefits, such as discriminating benign diseases from
malignancies, predicting cancer development and progression, checking sensitivity to treatment, and initial detecting of
tumors. This review summarizes the relationships between miRNAs and CEA, the diagnostic significance of CEA in
combination with miRNAs, and the distinct advantages of miRNAs over CEA as tumor biomarkers. Advancement in
our current understanding of miRNAs is very essential to discover new and effective biomarkers for diagnostic, prognostic,
and therapeutic goals of cancer patients.

Authors: Saruchi  , Saini Anjali , Kumar Vaneet
Published: June 2021

Introduction:

Plants have been used for thousands of years to treat health disorders, to
prevent diseases including epidemics, to flavor and conserve food. It is estimated that 250 to 500
thousand plant species are present on the earth, out of which merely 10 percent are used as a
source of food by humans and animals.

Objective:

In the present work, antibacterial activity of five different Indian spices namely turmeric,
clove, pepper, cinnamon and garlic was investigated against pathogens isolated from
wound samples

Method:

The unknown bacteria were identified by different types of morphological and biochemical
techniques such as serial dilutions spread plate methods, morphological studies and biochemical
tests. The swabs of the patients were inoculated in 10 mL of sterile nutrient broth and
incubated at 37oC for 24 h. The antibacterial activities of these Indian spices were evaluated using
the disk diffusion method. A suspension of the microorganisms to be tested was spread on nutrient
agar and MacConkey agar medium. The filter paper discs were placed on the agar plates,
which were saturated with extract of spice. The plates were then incubated at 37oC for 24 h. The
zone of inhibition was determined post-incubation by evaluating the diameter of the zone of inhibition.

Results:

The antibacterial activities of these Indian spices were evaluated using the disk diffusion
method, and the inhibitory zones were recorded. It was quite evident from the result
that cinnamon had a larger inhibition zone against P1NA3, P1MAC1 and least for P2NA2.
Garlic exhibited a greater zone of inhibition against P2NA2, P3NA3 and least for P1MAC1.
Clove had a maximum zone of inhibition against P1MAC2 and least with P3NA3. These
spices displayed a zone of inhibition somewhat close to the control antibiotic drug, ampicillin.

Conclusion:

P1MNC2 showed a maximum zone of inhibition with clove (3 cm) at 100%. P2NA2
showed maximum antibacterial activity with garlic (3.6 cm) at 100% and minimum with cinnamon
(1.1cm) at 20%. P3NA3 presented maximum antibacterial activity result with garlic (4.2 cm)
at 100% and minimum with clove (1.2cm) at 20%. Spices are economical, more accessible to
most of the population in the world. So, medicinal plants should be encouraged as potential candidates
for new drugs.

Kiprah lembaga penelitian dan pengembangan milik pemerintah sudah ada sejak lama, baik unit yang berada di bawah kementerian atau perguruan tinggi maupun yang independen dalam struktur Lembaga Pemerintah Non Kementerian bidang Riset dan Teknologi (LPNK Ristek). Namun, panjangnya eksistensi LPNK Ristek dinilai tidak sejalan dengan output hasil litbang karena minimnya kontribusi LPNK Ristek dalam melakukan hilirisasi hasil kegiatan penelitian dan pengembangan (litbang) ke para pengguna. Studi ini berupaya memberikan pemahaman mengenai bentuk desain kebijakan yang berangkat dari isu minimnya hilirisasi/komersialisasi hasil litbang di Indonesia dengan kebijakan transfer teknologi yang sudah ada dan mengusulkan alternatif kebijakan baru, yakni Technology Transfer Office (TTO) untuk menggantikan kebijakan yang lama. Pendekatan studi ini adalah kualitatif dengan metode desk research, di mana sumber data yang digunakan diperoleh melalui sumber sekunder dari dokumen tertulis, jurnal ilmiah, buku ilmiah, arsip, kebijakan atau regulasi yang terkait, dan penelusuran dari website lembaga terkait. Sumber data tersebut dipublikasikan dalam rentang waktu tahun 1996 hingga tahun 2020. Hasil dari studi ini menemukan ada tiga hambatan transfer teknologi di lembaga litbang Indonesia yakni minimnya pendanaan, terbatasnya kualitas dan kuantitas SDM, serta struktur kelembagaan yang kaku dan menghambat fungsi transfer teknologi. Studi ini juga merekomendasikan kebijakan TTO sebagai alternatif kebijakan transfer teknologi dengan empat instrumen utamanya yakni (1) dari aktivitas pemerintah yang terlibat, (2) struktur sistem penyampaian baik langsung atau tidak langsung, (3) derajat sentralisasi, dan (4) derajat automisasi dengan mekanisme pendanaan, SDM, dan kelembagaan berupa Badan Layanan Umum (BLU).

Authors: Nurfauzi Alfian
Published: June 2021

Carbon monoxide gas is a gas from combustion and this gas can enter vehicles, especially cars, so that it can endanger the safety of passengers. Carbon monoxide is a gas that is odorless, colorless and tasteless so that it cannot be felt by the human senses but is dangerous because it can inhibit the distribution of oxygen in the body. Based on this, this research was conducted to develop a carbon monoxide detector prototype in the vehicle cabin to detect carbon monoxide. The development process consists of needs analysis, making tool designs, simulating tool performance using software and making prototypes. The prototype not only detects carbon monoxide in the car but also circulates the air inside the car so that toxic gases can come out when the detected carbon monoxide exceeds the threshold.

In this paper, we experimentally demonstrate the generation of the second harmonic radiation of the gyrotron with an operating frequency of 263 GHz due to the second order lattice nonlinearity in indium phosphide crystals doped with ferrum. It is shown that the second harmonic radiation can be used for magnetospectroscopy of semiconductor nanostructures. We discuss the possibility of generating a difference frequency in these crystals when excited by two sources of the mid-IR range with a close wavelength.

Authors: Scabra Andre Rachmat , Budiardi Tatag
Published: June 2021

One potential aquaculture commodity that can be developed is Anguilla bicolor. One effort that can be conducted to maximize the life and growth of A. bicolor by manipulating water quality through alkalinity parameters. Alkalinity is a buffer capacity for changing in water pH, and osmotic pressure of water. Alkalinity levelss in culture media can be managed by the addition of calcium carbonate (CaCO3), calcium oxide (CaO), or calcium hydroxide (CaOH) with a certain dose to the culture media. This study aimed to determine the effect of alkalinity on aquaculture media based on the level of oxygen consumption (OC) that related to growth value. This research was conducted with an experimental design using a completely randomized design (CRD) with four treatments, namely the addition of CaCO3 to maintenance media with different doses (A, 0 mg/L; B, 50 mg/L; C, 100 mg/L; D, 150 mg/L). The results showed that the treatment B (50 mg / L) showed an OC value (0.15 mgO2/g/h) and an optimal Growth Rate (GR) (3.75 g/day), while the Survival Rate (SR) parameter, the treatment had no significant effect. The conclusion was 50 mg/L of calcium carbonate (CaCO3) having the optimum alkalinity level in A. bicolor culture media. At the additional dose of CaCO3, the growth value (GR), and the level of eel fish oxygen consumption were optimal.

Published: June 2021

One way to increase cultivation productivity is by increasing stocking. Gouramy is a freshwater commodity that has a fairly slow growth performance. This study aims to determine the growth performance of gouramy reared at different stocking densities. The 3 cm gourami are reared in a pond containing 35 liters of water. ponds P1 (30 heads), P2 (50 heads), P3 (100 heads), P4 (150 heads), P5 (200 heads) each was repeated 3 times. Growth rate (GR), specific growth rate (SGR), survival rate (SR), and feed conversion ratio (FCR) were measured and analyzed for variance (ANOVA) followed by LSD. The results showed that the fish reared in pond P1 showed the best GR, SGR, FCR, and SR (3.8 g, 3.99 %, 96 %, and 1.11 respectively). The lower the density, the better the growth performance but based on efficiency and productivity the best is at P2.

A partir do caso do programa de “Pacificação” de favelas no Rio de Janeiro, iniciado em 2008 e cujo objetivo foi combater a criminalidade violenta através da “ocupação" dessas localidades pela Polícia Militar, analiso os “efeitos”' da “pacificação" para além das fronteiras das favelas. Dez anos depois, e após ser realizado em 38 favelas, o fim do projeto foi anunciado durante a "intervenção federal” na segurança fluminense. Contudo, baseando-me em pesquisa etnográfica e na literatura, argumento que um dos “legados" das Unidades de Polícia Pacificadora foi a disseminação de um ordenamento social calcado na “militarização” da vida, que não é exclusivo do Brasil, mas cujas repercussões ficaram evidentes em nossos eventos políticos mais recentes.
Pela revolução na periferia – notas introdutórias sobre a teoria do desenvolvimento desigual e combinado de Leon Trotsky
Authors: Barros Matheus de Carvalho
Published: June 2021

O presente trabalho tem por objetivo analisar de forma introdutória a teoria do desenvolvimento desigual e combinado de Leon Trotsky, considerada por alguns de seus interpretes a principal contribuição teórica do revolucionário russo ao marxismo. A tese desenvolvida por Trotsky não é apenas uma reflexão sobre as contradições econômicas e sociais de países de capitalismo periférico. É também uma das principais tentativas teóricas de rompimento com o evolucionismo e mecanicismo característicos do marxismo da Segunda internacional. Os estudos sobre as particularidades do desenvolvimento social russo produzidos por Trotsky serviram de base não apenas para a construção de uma teoria da revolução que estivesse assentada sobre a realidade concreta da Rússia, mas também estava carregada implicitamente de uma significação mais abrangente, aplicável ao conjunto de diversas formações sociais situadas na periferia do capitalismo. Portanto, a finalidade deste artigo é examinar de forma sucinta os principais pontos da teoria do desenvolvimento desigual e combinado, considerando-a indispensável para qualquer perspectiva de transformação social.

O presente artigo tem por objetivo apresentar o currículo de dois programas de formação de professores que podem ter o potencial de atender às demandas de formação continuada de professores frente aos novos desafios educacionais. O primeiro é o Programa VET III - Teacher for the Future, estruturado por educadores finlandeses, e o segundo é o curso MAES Metodologias Ativas de Aprendizagem para o Estudante do Século XXI, estruturado por educadores brasileiros egressos do Programa VET. Trata-se de uma pesquisa qualitativa, descritiva e explicativa. Os referenciais teórico-metodológicos pautam-se na pesquisa aplicada, com características da etnografia. Dentro dos aspectos modificados pelo MAES destacam-se: o público-alvo, acréscimo de rubricas e narrativas como instrumento de avaliação, concomitância da formação com a atuação e a individualização do currículo.
Autoimmunity and Antibody Dependent COVID-19 Enhancement of SARS CoV-2 Vaccination: A Global Human Right to Know then Decide.
Authors: Kelleni Mina
Published: June 2021

mRNA based and adenovirus vectored vaccines, were first ever or first
commercially ever approved for the public, respectively. However, these
new types possess a potential risk to induce auto-immune diseases e.g.,
thrombocytopenia and some of these complications might also reason for
some of the post vaccination sudden death reports e.g., autoimmune
myocarditis and immune induced thrombosis and thromboembolism. Moreover,
all SARS CoV-2 types of vaccines, depending on the spike protein
immunogenicity, especially the conventional inactivated ones might
increase the likelihood of COVID-19 severity upon re-infection through
antibody dependent enhancement which might reason for the recently
described abundance of hospital admissions within seven days of
vaccination and might also reason for some of the serious adverse
effects encountered with administration of convalescent plasma to
COVID-19 patients. Furthermore, SARS CoV-2 vaccines might share in
development of some lethal SARS CoV-2 variants. Finally, we suggest that
making these COVID-19 vaccines compulsory is a crime against humanity
and an informed personalized risk benefit ratio especially for described
high risk groups must be secured.
Activation of neuronal nicotinic receptors inhibits acetylcholine release in the neuromuscular junction by increasing Ca2+ flux through Cav1 channels
Authors: Zhilyakov Nikita , Arkhipov Arsenii , Malomouzh Artem , Samigullin Dmitry
Published: June 2021

Background and Purpose: Cholinergic neurotransmission is a key signal
pathway in the peripheral nervous system (PNS) and in several branches
of the central nervous system (CNS). Despite the fact that it has been
studied extensively for a long period of time, some aspects of its
regulation still have not yet been established. One is relationship
between nicotine-induced autoregulation of acetylcholine (ACh) release
with changes in the concentration of presynaptic calcium levels.
Experimental Approach: The mouse neuromuscular junction of m. Levator
Auris Longus was chosen as the model of the cholinergic synapse. ACh
release was assessed by electrophysiological methods. Changes in the
calcium transients were recorded using a calcium-sensitive dye.
Functional interaction between nicotinic ACh receptors and calcium
channels was investigated pharmacologically using specific agonists and
antagonists. Key Results: Nicotine hydrogen tartrate salt (considered as
a stable form for potential therapeutic delivery of nicotine) effects on
the parameters of ACh release from the nerve ending were analyzed.
Nicotine application (10 μM) decrease the amount of evoked ACh release,
while calcium transient increase in the motor nerve terminal. Both of
these effects of nicotine were abolished by the neuronal ACh receptor
antagonist dihydro-beta-erythroidine and Cav1 blockers, verapamil and
nitrendipine. Conclusion and Implications: Neuronal nicotinic ACh
receptors activation decreases the number of ACh quanta released by
boosting calcium influx through Cav1 channels. Understanding of
mechanisms of autoregulation of ACh release is important for the
searching new approaches treat diseases associated with cholinergic
dysfunction.
Ecological theory of mutualism: Qualitative patterns in two-species population models
Authors: Hale Kayla , Valdovinos Fernanda
Published: June 2021

Mutualisms are ubiquitous in nature, provide important ecosystem
services, and involve many species of interest for conservation.
Theoretical progress on the population dynamics of mutualistic
interactions, however, has comparatively lagged behind that of trophic
and competitive interactions. Consequently, ecologists still lack a
generalized framework to investigate the population dynamics of
mutualisms. Here, we review historical models of two-species mutualisms
from over the last 90 years. We find that population dynamics of
mutualisms are qualitatively robust across derivations, including levels
of detail, types of benefit, and inspiring systems. Specifically,
mutualisms exhibit stable coexistence at high density and destabilizing
thresholds at low density. We distinguish between thresholds resulting
from Allee effects, low partner density, and high partner density, and
their mathematical and conceptual causes. The dynamics of stable
coexistence and thresholds in partner density emerge when benefits of
mutualism saturate, whether due to intrinsic or extrinsic density
dependence in intraspecific, interspecific, or both. These results
suggest that there exists a robust population dynamic theory of
mutualism that can make general predictions.
Extracorporeal membrane oxygenation for the control of a pulmonary artery hemorrhage

Published: June 2021

No standard treatments have been established for airway hemorrhage
during cardiopulmonary bypass (CPB). Herein, we describe two cases of
catheter-induced pulmonary hemorrhage during cardiac surgery. In each
case, massive hemoptysis was observed during cardiopulmonary bypass
(CPB) weaning. A bronchial blocker was inserted into the right bronchus,
and extracorporeal membrane oxygenation (ECMO) was initiated to reduce
pulmonary blood flow, and stabilize the hemodynamics. ECMO significantly
reduced bleeding from the pulmonary artery (PA). Both cases had
favorable outcomes following the implementation of extracorporeal
membrane oxygenation (ECMO). ECMO is effective at controlling PA
bleeding during and after cardiac surgery.
Relationship Between Parenting Style and Establishment of Religious Characters at Taman Pendidikan Alquran (TPA) Masjid Alfurqon Desa Sikuliek Kecataman Koto Tangah Kota Padang
Authors: Guchi Gilang Ariesta , Sunarti Vevi
Published: June 2021

This research was motivated by the low religious character of children studying at the Al-Furqon Mosque Education Park (TPA), Sikuliek Village, Koto Tangah District, Padang City. This is most likely due to ineffective and inaccurate parenting parents, which have a negative impact on the child's personality, especially in the development of religious character. Based on this phenomenon, the aim of this study is to describe the parenting parents of the parents in relation to the child, to describe the religious character of the child, and to determine the relationship between the parenting parentsof the parents and the development of the religious character of the child. Correlational quantitative analysis is the term for this form of study. All children who learned the Koran at the Al-Furqon Mosque Education Park were included in this report (TPA). Saturated samples were used as a sampling method. A questionnaire is the data collection method, and a list of statements is the data collection tool. The percentage formula and  sperman rho were used in the data analysis technique. The results showed that low parenting parent, low religious character of children and there is a significant relationship between parenting parentswith the formation of children's religious character. Suggestions in this study are that parents are expected to be able to choose and sort out what parenting parents to apply to children, pay more attention to children and become role models for their children because the family environment is very much determined by the formation of children's religious character and the existence of cooperation between parents and administrators TPA to participate in motivating children to continuously attend lessons at the TPA so as to maximize the formation of children's religious character.Keywords: Parenting Parents, Religious Character

¿Qué intervenciones pueden tener los analistas en el lazo social?
Authors: Ale Marcelo
Published: June 2021

Si a los analistas nos interesa la cultura en la que vivimos es porque esta incide sobre la práctica analítica. La clínica no es impermeable al estado contemporáneo de la cultura que desembarca con sus discursos dominantes en los divanes. Las teorías del malestar dependen de la época en la que nos toca vivir. En psicoanálisis no hay modo de anoticiarnos de ese malestar sino es por su portavoz, el síntoma, que siempre ha tenido una envoltura formal, un modo de presentación que depende del Otro al cual se refiere. Las épocas, definidas por el predominio de los discursos imperantes, varían. Es diferente la época victoriana en la que Freud funda el psicoanálisis que la actual: en aquella se tendía a la represión de la satisfacción sexual, en esta a su promoción. Si las épocas varían, el psicoanálisis está obligado a reconsiderar su “intervención en lo social,” instalándose esta como un tema de debate permanente.
