Authors: Castro Gillianno José Mazzetto de , Costa Márcio Luís
Published: July 2022

Este artigo tem por objetivo pensar os contextos e cenários da pandemia da COVID-19 a partir da categoria de vulnerabilidade entendida como abertura original para e na vida. Para tanto se fará um estudo fenomenológico de base Henriana que se pergunta pela possibilidade e dinâmicas de modalização da vida dentro dos contextos oportunizados pela pandemia. Com este intuito se fará uma distinção entre fragilidade e vulnerabilidade, na sequência se explorará a ideia do duplo aparecer e da afetação a partir do provar-se a si mesmo com os outros sobre a forma de cuidado e por fim, se pensará alguns contextos e possíveis interlocuções para as pesquisas e práticas psicológicas dentro deste cenário. Como possíveis conclusões se pode observar que a pandemia tem produzido uma dimensão importante ainda a ser explorada, a saber, o desenvolvimento da ideia de hábito de vida não apenas como práticas, mas como fluxo e como vínculo afetivo anteriores a ideia de sujeito e de identidade.

Tenencia y lucha por la tierra en la parte alta de La Bella. Pereira 1970- 1980
Authors: Villegas Hincapié Elsa María
Published: July 2022

La Bella, corregimiento de Pereira, en 1970 era un paraje rural con fincas tradicionales de pan coger. En esta década se dieron dos procesos: uno, la lucha campesina por la tierra y la consolidación de la Ley 135 de 1961 con La Hacienda Santacoloma ubicada en La Bella; y, dos, el reemplazo del café tradicional y la ganadería por el monocultivo de la cebolla larga (Allium fistulosum) en otra vereda cercana, La Florida. Este artículo resalta la voz de algunos campesinos protagonistas para comprender la lucha por la tierra y su incidencia en la nueva forma de producción agrícola.
Sánchez Calderón, Fabio Vladimir. La urbanización del río Tunjuelo: desigualdad y cambio ambiental en Bogotá a mediados del siglo XX. (Bucaramanga: Ediciones UIS, 2021)
Authors: Hernández Quiñones Oscar Daniel
Published: July 2022

El trabajo de Vladimir Sánchez está compuesto por un prólogo, introducción, cuatro capítulos, conclusiones y una sección de anexos. Tiene por objeto analizar la relación socioambiental que se tejió a mediados del siglo XX entre: (1) la acelerada urbanización de Bogotá –apoyada en el uso de materiales compuestos como el concreto reforzado; (2) la minería de agregados en el río Tunjuelo con la que se quiso apalancar esa gran transformación; y (3) la ocurrencia periódica de inundaciones en los barrios Tunjuelito, Meissen y San Benito, todos ubicados a las orillas del Tunjuelo y expuestos a desastres cuyas causas fueron atribuidas desde el discurso oficial y periodístico a la violencia “espontánea” de la naturaleza o a la ignorancia de los habitantes de la zona, aun cuando la influencia de la extracción minera sobre los cambios en la dinámica del río ya estaba identificada en la época

Published: July 2022

Glucosamine (GlcN) is a natural amino monosaccharide in which a hydroxyl
group of glucose is substituted for an amino group. It belongs to
functional amino sugar compounds. The traditional GlcN production method
is prepared by hydrolyzing the exoskeleton of shrimp and crab. This
method has many potential problems such as geographical and seasonal
restrictions on raw material supply, serious environmental pollution and
potential allergic reactions. The microbial fermentation method has the
advantages of short fermentation time, high production intensity, wide
source of raw materials, green and sustainable process, and product
safety. This paper mainly summarizes the research on strain
construction, metabolic pathway design, and fermentation condition
optimization in microbial fermentation, which has certain guiding
significance for the further production of glucosamine.

Authors: T Nnamocha, O. , Azuka Chinenye , Nkama Iro
Published: July 2022

Moisture sorption characteristics of gari sold in Ebonyi, Enugu, and
Abia state were studied. The gari samples were coded thus; Abia white
gari sample (ABW), Abia yellow gari sample (ABY), Ebonyi white gari
sample (EBW), Ebonyi yellow gari sample (EBY), Enugu white gari sample
(ENW) and Enugu yellow gari sample (ENY), accordingly. The equilibrium
moisture content (EMC) was determined using a standard Gravimetric
method with tetraoxosulphate (VI) salt and water mixtures providing
equilibrium relative humidity (ERH) 15, 25,35, 45, 55 and 65 % to yield
a water activity (aw) range of 0.0972 - 0.9811 at 30, 40 and 50
C for adsorption and desorption isotherm arms. The
sorption data generated were fitted into GAB and Handerson models. A
sigmoidal behaviour ( type II) was observed which is a typical attribute
of a dry carbohydrate dense food. There was a general increase in the
equilibrium moisture content (%) with increasing water activity. A
little difference was observed between the sorption behaviour of ABW,
EBW and ENW; ABY, EBY and ENY gari sample. The equilibrium moisture
content decreased with increase in temperature at constant water
activity. The goodness fit of the two models were determined using four
statistical parameters; coefficient of determination (r
), root mean square error (RMSE), percentage mean
relative deviation modulus (%p) and chi square (x ).
GAB model appeared as the most suitable model than Henderson model. EBW
and EBY gari samples proves to be of good shelf stability.
Access to Pediatric Oncology Rehabilitation in Latin America: perception of healthcare providers
Authors: B. Pia Delano , Lopez Rodrigo
Published: July 2022

Background The role of cancer rehabilitation is key in
maintaining functional role and improving quality of life.
Rehabilitation is in the CureALL program, which aims to achieve at least
60% survival for children with cancer globally while ensuring that
suffering is reduced for every child with cancer. The demand for
pediatric cancer rehabilitation will increase as the life expectancy of
these children improves, but not all countries in Latin America are
prepared for it. With the support of Sociedad Latinoamericana de
Oncologia Pediatrica (SLAOP), the aim is to describe the existing
resources that provide rehabilitation to these children with cancer.
Methods A survey was sent to all members of the 21 countries of
SLAOP. The survey had 10 questions regarding different aspects of
rehabilitation, access, and barriers. Results Out of the 22
countries who are members of SLAOP, we had responses from 19 with a
total of n=123 responses. Most healthcare providers (98.4%) know the
importance of rehabilitation in pediatric oncology, and 86.2% had
rehabilitation teams. Only 19 respondents said they had pediatric
oncology rehabilitation educational programs. Barriers to access
rehabilitation were reported by 83% providers: Approachability (n=25),
Acceptability (n=4), Availability (n=76), Affordability (n=35),
Appropriateness (n=24) The main barriers associated with availability
were Distance (n=31) and Lack of health care professionals (n=39).
Conclusions While the importance of pediatric oncology
rehabilitation is known in Latin America, there are many factors that
act as barriers to access to care for children and adolescent with
cancer. It is key to address these barriers to improve the quality of
life of Latin American pediatric oncology patients.
Dynamic fracture behavior analysis of FRP-strengthened concrete based on DIC and AE technology
Authors: Liu Jueding , Xiangqian Fan , Lei Tang , Yuxiao Ye , Fei Ge
Published: July 2022

In order to analyze the fracture behavior of FRP-strengthened concrete
beams under dynamic loads, three-point bending dynamic tests of
FRP-strengthened concrete beam specimens with four different initial
crack-depth ratios (0.2, 0.3, 0.4 and 0.5) were carried out in this
paper. The crack propagation was quantitatively analyzed by acoustic
emission (AE) technique and digital image correlation (DIC) method, and
the toughening mechanism of FRP-strengthened concrete beam during crack
propagation was studied. The test results show that, there are three key
points in the failure process of FRP-strengthened concrete beams with
cracks, which are the crack initiation point, crack resistance point and
peak load point, respectively. The load values at the three key points
of FRP-strengthened concrete beams with cracks decrease with the
increase of initial crack-depth ratios. The location analysis of AE
shows that the number of AE events can be used to indicate the crack
width in the fracture process zone (FPZ) of FRP-strengthened concrete.
The crack width of concrete beam specimens can be quantitatively
determined by DIC and decrease with the increase of initial crack-depth
ratios, indicating that observation results of DIC and AE technology are
consistent, which is effective for characterizing the dynamic fracture
behavior of concrete materials.
Understanding the helical stability of charged peptides
Authors: Singh Nitin Kumar , Agarwal Manish , Radhakrishna Mithun
Published: July 2022

Cationic helical peptides play a crucial role in applications such as
anti-microbial and anti-cancer activity. The activity of these peptides
directly correlates with their helicity. In this study, we have
performed extensive all-atom molecular dynamics simulations of 25
Lysine-Leucine co-polypeptide sequences of varying charge density ( λ )
and patterns. Our findings showed that an increase in the charge density
on the peptide leads to a gradual decrease in the helicity up to a
critical charge density λ c . Beyond, λ c a complete helix to coil
transition was observed. The decrease in the helicity correlated with
the increased number of water molecules in first solvation shell,
solvent-exposed surface area, and a higher value of the radius of
gyration of the peptide.

This work described the performance of consensus control of the second-order networked multi-agent system with CAN bus-induced delay. First, the characteristics of controller area networks (CAN) buses and the main causes of CAN bus induce a delay in distributed networked control systems (DNCS) were analysed. Secondly, DNCS is converted into a model of networked multi-agent systems in the frequency domain. Then based on the designed model of networked multi-agent systems, an analytical H2 controller is proposed for performance tracking. Moreover, a complementary sensitivity function is used to assess the robustness of the proposed controller. In the end, delay margin criteria are derived for the consensus of a networked multi-agent system in the presence of CAN bus-induced delay. The results obtained by simulating the second-order networked multi-agent system verified the usefulness of the proposed control protocol.

Area and power-efficient reconfigurable digital down converter on FPGA
Authors: Datta Debarshi , Dutta Himadri
Published: July 2022

This paper presents a field-programmable gate array (FPGA)-based digital down
converter (DDC) that can reduce the bandwidth from about 70 MHz to 182.292
kHz. The proposed DDC consists of a polyphase COordinate Rotation DIgital
Computer (CORDIC) processor and a multirate filter. The advantage of
polyphase CORDIC processor is to process with high sample rate input data
and produces computational efficient noiseless baseband spectrum. The
pipeline multirate filter works at a high clock speed. Moreover, the
multirate filter generates a fractional sample rate factor using a cubic
B-spline Farrow filter. The proposed DDC is coded with optimal hardware
description language (HDL) and tested on Kintex-7 Xilinx FPGA as the target
device. Experimental results indicate that the proposed design saves chip
area, power consumption and operates at high speed without loss of any
functionality. Additionally, the proposed design offers sufficient
spurious-free dynamic range (SFDR) and produces less than 1 Hz frequency
resolution at the output.
Optimization of the 3p keys kernel parameters by minimizing the ripple of the spectral characteristic
Authors: Savic Natasa , Milivojevic Zoran , Velickovic Zoran
Published: July 2022

The ideal interpolation kernel is described by the sinc function, and its spectral characteristic is the box function. Due to the infinite length of the ideal kernel, it is not achievable. Therefore, convolutional interpolation kernels of finite length, which should better approximate the ideal kernel in a specified interval, are formed. The approximation function should have a small numerical complexity, so as to reduce the interpolation execution time. In the scientific literature, great attention is paid to the polynomial kernel of the third order. However, the time and spectral characteristic of the third-order polynomial kernels differs significantly from the shape of the ideal kernel. Therefore, the accuracy of cubic interpolation is lower. By optimizing the kernel parameters, it is possible to better approximate the ideal kernel. This will increase the accuracy of the interpolation. The first part of the paper describes a three-parameter (3P) Keys interpolation kernel, r. After that, the algorithm for optimizing the parameters of the 3P Keys kernel, is shown. First, the kernel is disassembled into components, and then, over each kernel component, Fourier transform is applied. In this way the spectral characteristic of the 3P Keys kernel, H, was determined. Then the spectral characteristic was developed in the Taylor series, HT. With the condition for the elimination of the members of the Taylor series, which greatly affect the ripple of the spectral characteristic, the optimal kernel parameters (?opt, ?opt, gopt) were determined. The second part of the paper describes an experiment, in which the interpolation accuracy of the 3P Keys kernel, was tested. Parametric cubic convolution (PCC) interpolation, with the 3P kernel, was performed over the images from the Test database. The Test database is created with standard Test images, which are intensively used in Digital Image Processing. By analyzing the interpolation error, which is represented by the Mean Square Error, MSE, the accuracy of the interpolation was determined. The results (?opt, ?opt, gopt, MSEmin) are presented on tables and graphs. Detailed comparative analysis showed higher interpolation accuracy with the proposed 3P Keys interpolation kernel, compared to the interpolation accuracy with, 1P Keys and 2P Keys interpolation kernels. Finally, the numerical values of the optimal kernel parameters, which are determined by the optimization algorithm proposed in this paper, were experimentally verified.

Wood ash is a complex mixture of inorganic and organic compounds. It is heterogeneous in composition, which can vary considerably. Ash is mainly disposed of in landfills, which creates a risk for air, soil and groundwater contamination by trace elements. In order for wood biomass ash to be used as a secondary raw material, it is necessary to perform leaching tests, to determine which microelements it contains, and which of them could be released into the environment during the ash disposal. Sequential extraction (SE) showed that in the exchangeable and carbonate fraction, the most volatile metals As, Cd, Zn and Pb are released the most from the ash of deciduous trees, while the leaching of ash from coniferous trees is significantly lower. The evaluation of risk assessment code (RAC) for the tested biomass ash samples, indicates that Pb is a high-risk leaching element due to its condensation on the ash particles. By performing toxicity characteristic leaching procedure (TCLP) and synthetic precipitation leaching procedure (SPLP) tests, it was established that the released concentrations of tested metals are below the maximum allowable concentration, given by the regulation. The leaching tests of composites, prepared from wood ash in combination with cement, indicate that the leaching of ash is reduced to a minimum, and that all heavy metals are bound in a cement matrix, which indicates the possibility of using wood ash for construction purposes.
Three-dimensional assessment of palatal area changes after posterior crossbite correction with tooth-borne and tooth bone–borne rapid maxillary expansion: A randomized controlled trial with 5-year follow-up
Authors: Malmvind Damir , Golež Aljaž , Magnuson Anders , Ovsenik Maja , Bazargani Farhan
Published: July 2022

Objectives

To assess and compare the three-dimensional treatment changes in palatal surface area and volume using either tooth-borne (TB) or tooth bone–borne (TBB) rapid maxillary expanders and to evaluate the long-term effects of the two devices and the incidence of the relapse between the groups.

Materials and Methods

A total of 52 consecutive patients who met the eligibility criteria were recruited and allocated to either the TB group, mean age 9.3 years (standard deviation [SD], 1.3), or the TBB group, mean age 9.5 years (SD, 1.2). Study casts were taken before, directly after, 1 year after, and 5 years after expansion. Study casts were digitized, superimposed, and evaluated. Participants were randomly allocated in blocks of different sizes using the concealed allocation principle in a 1:1 ratio.

Results

Changes in palatal volume, palatal surface area, and palatal projection area within and between the groups up to 5 years after expansion followed the same pattern and did not show any statistically significant differences between the groups. Relapse was seen in 15% of the patients. It seemed that open-bite and a Class III growth pattern could be assumed as prognosis-deteriorating factors in regard to stability of the treatment.

Conclusions

There were no significant differences between the TB and TBB groups in palatal volume, palatal shell area, or palatal projection area directly after expansion or at 1 year and 5 years after expansion, which implies that the two devices gave rise to the same immediate and long-term outcomes.

Barnehagelærarstudentars refleksjonar over barns fleirsanselege utforsking i naturfaglege samtaler
Authors: Fagerbakke Inga Margrethe
Published: July 2022

Artikkelen presenterer ein casestudie av tre studentar sine transkriberte samtaler om naturfaglege emne med barnehagebarn i alderen 2,5–4 år, og deira refleksjonar rundt desse. Formålet med artikkelen er å belysa korleis studentane stiller seg til barnas fleirsanselege utforsking som ein del av samtala. Funna viser at studentane, gjennom videoanalyse av seg sjølve, blir meir merksame på korleis dei kunne ha fylgt opp fleire av sanseinntrykka til barna og fått dei inn i samtalene. Studentane trekkjer fram manglande bruk av tid, at dei skiftar fokus og at dei stiller feil spørsmål, som forklaringar på kvifor dei ikkje lukkast. I dei tilfella der dei har lukkast, peikar dei på det å la barnet sansa som ein suksessfaktor. Funna viser at produktive spørsmål som handlar om å observera nøye, er ein måte å gripa fatt i barns fleirsanselege utforsking på, men at det ofte blir brukt hypotesedannande spørsmål i samtalene med barna, utan at dette bidrar til meir utforsking i samtalene. 
English abstract
Pre-service kindergarten teachers’ reflections over children’s multisensory exploration in scientific dialogues
The article presents a case study of three students’ transcribed conversations with and reflections on scientific conversations with kindergarten children between 2.5–4 years. The purpose of the article is to explain how the students position themselves to the children's multisensory exploration as part of the conversation. The findings show that the students, through video analysis of themselves, became more aware of how they could have followed up more of the children’s sensory impressions, and brought it into the conversations. Students point to their lack of use of time, shift of focus, and asking the wrong questions, as explanations for why they are failing. In those cases where they have succeeded, it is pointed out to let the child sense, as a success factor. The findings show that productive questions that are about observing carefully are a way of tackling children’s multisensory exploration, but that hypothesis-forming questions are often used with the children, without this contributing to more exploration in the conversation.

Coffee is widely consumed around the world, also considered one of the most important beverages today.  Factors contributing to the quality of coffee beans such as color, texture, size, aroma, etc. and other processes along the production chain such as plant, roasting, and grinding. Those processes will be worthless if the quality of the coffee bean is low. It is important to only use the best quality coffee beans. Therefore, the challenge is to develop a system that uses computer vision to either identify high quality beans or classify them by their species to ease the effort needed by all actors in the supply chain. Providing information for end customers is a defining factor to push forward the coffee industry. This paper aims to review literatures within the topic of using computer vision for coffee beans. After reviewing a selected number of studies which corresponds with the topic chosen in our paper, computer vision techniques were used for two main reasons, identification and classification. Researches on this topic are still limited. Hence, it can be concluded that there are still plenty of room for study on this topic. This study also aims to help provide research material for future researchers.

The Polemic of Wayang in Da’wah Stage: Digital Contestation for Religious Authority
Authors: Hasanah Umdatul , Anam Khairil
Published: July 2022

Understanding the polemic of wayang in da'wah, which is being discussed in the digital space, has shown how the contestation of religious authority is taking place. Differences in understanding, group background, culture, and interests as well as an ideology have made the dynamics of the contestation more complex. This article discusses the factors that influence the polemic about the use of wayang in da'wah in the digital space and complements the shortcomings of previous studies. This qualitative research uses the content analysis method on online media data and Twitter for a period of one month. The results of this study indicate that the contestation occurs not only in the gripping and traditional authorities but also in the new authorities who are present amid polemics. The media is part of an authority that has its logic, where media users are free to produce and market ideas in the digital space. This condition becomes a new problem that can undermine traditional authority's power and make the world of da'wah a religious contestation arena.

PT. Surya Baja Pipa Indonesia (SBPI) is a manufacturing company that produces hollow and pipe from rolled iron plate. The production data showed that during January up to October 2021 there were still defects products with the percentage greater than 5%, the specified tolerance limit for defects. In order to maintain quality and increase production efficiency, PT. SBPI strives to reduce the defect rate. This study aims to reduce the level of defect by using Statistical Process Control methods and the Failure Mode and Effects Analysis (FMEA) method to analyze the level of the worst defects by finding the highest damage value Risk Priority Number (RPN). Histogram showed that the biggest defect occurs in welding (7,51%). Analysis using Fishbone diagram found that the welding defect mostly occur due to human factor/workers, machines, methods, materials, and the environment. The result of FMEA method analysis showed machine setting had the highest RPN and became the first priority to solve. It happened because there is no SOP yet that contains definite engine parameters, such as engine speed and voltage. Based on these results, this study suggests companies to prepare SOPs to be a guide for operators at work.

Human error merupakan terjadinya kesalahan atau kegagalan dalam menyelesaikan suatu tugas pekerjaan sehingga menimbulkan gangguan terhadap jadwal operasi atau mengakibatkan kerusakan benda dan peralatan. Penelitian ini menggunakan dua metode identifikasi human error meliputi SHERPA dan HEART. kemudian, kajian ini melakukan perancangan layout sign system visual yang akan diletakan di lokasi human error terbesar. Perancangan layout ini menggunakan standar safety sign yaitu BS-ISO 3864:2011. BS-ISO 3864:2011 menetapkan standar internasional untuk tanda dan tanda keselamatan di tempat kerja dan fasilitas umum. Human error yang terjadi adalah operator memiliki alur kerja yang tidak searah sehingga alur kerja operator bolak-balik/berputar-putar, operator tidak memperhatikan bentuk batu yang diambil sehingga ukuran batu menjadi berbeda-beda, melakukan pemeriksaan terhadap ketebalan rumput yang diambil, jika tebal maka tanah bagian bawah rumput dapat di bersihkan terlebih dahulu. Implikasi pada kajian ini Apabila manusia dapat menjaga keselamatannya  maka bahaya sebenarnya dapat di hindari oleh manusia dengan cara yang lebih waspada terhadap apapun yang ada di sekitar mereka sebelum bahaya itu terjadi. Human error merupakan terjadinya kesalahan atau kegagalan dalam menyelesaikan suatu tugas pekerjaan sehingga menimbulkan gangguan terhadap jadwal operasi atau mengakibatkan kerusakan benda dan peralatan.

Mangrove dan kehidupan Suku Akit memiliki relasi yang erat sebagai sumber penghidupan. Namun, sejak dua dekade terakhir ketersediaan mangrove berkurang akibat aktivitas manusia dan faktor alam sehingga menyebabkan terjadinya abrasi. Tulisan ini menjelaskan praktik pelestarian dan orientasi nilai Suku Akit pada hutan mangrove. Kami menggunakan kualitatif melakukan wawancara dan observasi serta menganalisis secara deskriptif. Hasil penelitian mengungkapkan bahwa sampai saat ini Suku Akit masih memanfaatkan mangrove untuk kehidupan mereka, misalnya dalam bentuk kayu bakar, cerocok atau kayu fondasi rumah, pancang, maupun arang. Tetapi, pemanfaatan mangrove ini tidak dilakukan dalam jumlah yang besar, hal ini disebabkan karena adanya himbauan untuk mengurangi penebangan mangrove sebagai upaya mencegah abrasi. Beberapa orang mengikuti anjuran tersebut bahkan mereka sudah mulai bergerak mencari sumber penghidupan lain selain dari mangrove. Sebagian yang lain masih bekerja pada industri mangrove baik sebagai pelaku utama maupun pekerja. Temuan ini memberikan penekanan bahwa alternatif sumber penghidupan berkelanjutan selain bergantung pada mangrove sangat diperukan untuk kehidupan Suku Akit. Orientasi nilai mereka terhadap mangrove memiliki keterkaitan yang erat pada kondisi kehidupan mereka, sehingga diperlukan pemahaman serta alternatif pekerjaan lain agar tidak lagi memanfaatkan mangrove meskipun dalam jumlah yang kecil.
