Background:

Brazil is considered a country with the highest biological biodiversity in
the world and exploring underutilized food sources could diversify food production and reduce nutritional
problems.

Objective:

This study aimed to determine the antioxidant capacity and the bioactive compounds of
seven native fruits from Brazil.

Result:

The main carotenoid for all species was β-carotene, and Jaracatiá showed the highest
amount of β-cryptoxanthin, zeaxanthin, α- and β-carotene. Açaí Juçara and the Butiás stood out
among fruits analyzed with the highest antioxidant capacity (trolox equivalent). Concerning anthocyanins
in Açaí Juçara, compounds Cyanidin 3-glucoside and Cyanidin 3-rutinoside were identified.
The values of all the compounds vary according to the harvest location. Jaracatiá is distinguished
by the high vitamin A, C, B2, and B6 content, as well the Butiás (Praia and Serra), for B1,
B2, B5 and B7. Vitamin B3 was only detected in Fisális fruits and Açaí showed higher content of
B5.

Conclusion:

Fruits included in this study were found to have considerable amounts of bioactive
compounds, vitamins and antioxidant capacity, showing that they can contribute to the improvement
of diet of the population.

Published: March 2020

Background:

Vitamin D insufficiency and deficiency can be associated with adverse effects
on pregnancy outcomes, which may include recurrent pregnancy loss through the mechanisms
that are yet unknown. The aim of this study was to evaluate the effect of 1,25VitD3 on regulatory
T cells (Tregs) and T helper17 (Th17) cell populations In vitro in unexplained recurrent pregnancy
loss (URPL) patients and healthy women.

Methods:

Samples from 20 non-pregnant women with a history of URPL were compared to 20 normal
non-pregnant women. Peripheral blood mononuclear cells (PBMC) were divided into 3 wells
for each subject: in the presence of 1, 25 VitD3 (50 nM, for 16 hours), PHA (positive control)
(10μM), and without any treatment (as a baseline or negative control). The percentage of regulatory
T cells and Th17 cells was measured by flow cytometry at baseline and then after cell culture experiments.

Results:

Our study indicated that the percentage of Tregs in patients with URPL was significantly
lower than the control group (2.42 ± 0.27 vs. 3.41 ± 0.29, P= 0.01). The percentage of Th17 cells
was significantly greater in URPL patients compared to the control group (2.91 ± 0.33 vs. 1.18±
0.15, P=0.001). 1, 25VitD3 treatment significantly increased the percentage of Tregs from the baseline
in the URPL group compared to that in the control group (1.23 ± 0.03 vs. 1.00 ± 0.03, P=
0.01).

Conclusion:

Vitamin D deficiency may be a contributor to recurrent pregnancy loss and suggests
supplementation of women with Vit D pre-pregnancy may be protective against URPL.

Authors: Iio Misa , Miyaji Yumiko , Yamamoto-Hanada Kiwako , Narita Masami , Nagata Mayumi , Ohya Yukihiro
Published: March 2020

BACKGROUND

mHealth and uHealth apps are available for children with asthma and their caregivers. However, previous studies on mHealth apps for children older than 7 years old with asthma are limited, and most studies on asthma apps do not consider interactions involving communication between children and caregivers. Therefore, a prototype mHealth child asthma app was developed for children and their caregivers, with features of tailored feedback messages in continuing self-management and interactions between children and caregivers.

OBJECTIVE

The aim of this study was to identify the beneficial features of a prototype mHealth app developed for children with asthma and their caregivers.

METHODS

Children diagnosed with persistent asthma by allergy specialists at the National Center for Child Health and Development were recruited. The features of a prototype mHealth app for children with asthma and their caregivers were investigated using semistructured interviews after they tried the app. Data were analyzed using thematic analysis. Content-characteristic words were named and grouped together as categories to explore themes.

RESULTS

We recruited 27 children with asthma aged 2 to 12 years and 26 their caregivers. Findings on the good aspects of the app for children older than 7 years old and caregivers suggested 4 themes (confirmation of asthma knowledge, child-caregiver interaction, design of the app, and child’s interest), and 6 categories were identified. Findings on the good aspects of app for children 7 to 12 years old and caregivers suggested 5 themes (new knowledge, manga as a Japanese-style comic, child’s interest, trigger of self-management, and design and operability), and 11 categories were identified. Findings on the beneficial features of app suggested 6 themes (asthma knowledge, elements for continuous, universal design, notification, monitoring, and functions), and 12 categories were identified.

CONCLUSIONS

Children with asthma and their caregivers perceived that the good aspects of the app were learning asthma knowledge with fun, including manga; interaction between child and caregiver; and easy-to-read design, such as colors. They wanted not only the asthma knowledge but also the universal design and enhanced elements, monitoring, and notification functions of the app.

El derecho humano a la jurisdicción efectiva como norma jus cogens
Authors: Farinella Favio
Published: March 2020

Analizamos en este articulo la posible caracterización del derecho a la jurisdicción efectiva como norma jus cogens. Las normas imperativas de derecho internacional se imponen a la voluntad soberana de los Estados. En este sentido la limitan y contienen, formando parte del creciente orden público internacional impulsado en la segunda posguerra a partir de la teoría de los derechos humanos. La gran pregunta y posible desarrollo futuro consiste en saber si el acceso a la jurisdicción puede interpretarse como una de las normas imperativas de derecho internacional -con los efectos comentados- cuando el derecho violentado por el cual se pretende acceder a la jurisdicción, posee ese mismo carácter, idea afirmada por el Dr. Cancado Trindade en su disidencia en el caso Alemania-Italia, fallado por la Corte Internacional de Justicia (2012).

Published: March 2020

La creación de la Guardia Nacional ha sido anunciada como un elemento fundamental de la nueva estrategia de seguridad pública en México. Sin embargo, el análisis de la configuración constitucional y legal de sus potestades de inteligencia a la luz de los derechos humanos muestra una sorprendente similitud con la actual Policía Federal. Esta similitud bien puede ser interpretada como una continuidad de la policía federal, pero con un ingrediente de militarización en sus primeros años de vida.

Mathematical modelling of diced konjac corms drying in a fluidised bed dryer
Authors: Montreepila Montree , Poomsa-Ad Nattapol , Wiset Lamul
Published: March 2020

Konjac glucomannan (KGM) can be obtained from tubers (called corms) of various species within the Amorphophallus genus. Among the most popular species for use in food industry is Buk Nuea Sai (Amorphophallus muelleri), a native species in Thailand. Drying process can be helpful in preserving KGM during long storage periods. However, the existing drying systems are often slow and lead to drying delays and subsequently quality reduction of the dried product. Given the economic importance of KGM, new, more efficient drying systems, have to be developed. The present study focuses on the drying kinetics of konjac dices in a fluidized bed, operating at a constant air velocity of 2.5 m/s and air temperatures of 50, 60, and 70?C. Six empirical mathematical models were selected to describe and compare the drying characteristics of konjac dices subjected to these conditions. The model coefficients were determined by non-linear regression analysis. Among the tested models used to describe the drying kinetics of konjac dices, the two-term model was found as the best one. The moisture loss from the dice was described by the Fick?s diffusion equation, and based on the obtained results the effective moisture diffusivity was estimated, getting a value in the range between 9.60526 ? 10?9 m2/s and 1.2006 ? 10?7 m2/s. The relationship between the temperature and the effective moisture diffusivity was described adequately by means of Arrhenius-type equation. An activation energy value between 8.65 kJ/mol and 61.28 kJ/mol was obtained. The findings allow the successful simulation of konjac dice drying in a fluidized bed between 50 and 70?C, 30-60 mm bed height and 6-15 mm dice thickness.
A new class of A-stable numerical techniques for ordinary differential equations: Application to boundary-layer flow
Authors: Nawaz Yasir , Arif Muhammad
Published: March 2020

The present attempt is made to propose a new class of numerical techniques for finding numerical solutions of ODE. The proposed numerical techniques are based on interpolation of a polynomial. Currently constructed numerical techniques use the additional information(s) of derivative(s) on particular grid point(s). The advantage of the presently proposed numerical techniques is that these techniques are implemented in one step and can provide highly accurate solution and can be constructed on fewer amounts of grid points but has the disadvantage of finding derivative(s). It is to be noted that the high order techniques can be constructed using just two grid points. Presently proposed fourth order technique is A-stable but not L-stable. The order and maximum absolute error are found for a fourth order technique. The fourth order technique is employed to solve the Darcy-Forchheimer fluid-flow problem which is transformed further to a third-order non-linear boundary value problem on the semi-infinite domain.
A new method for evaluating the joint effect of draught and the hot ceiling
Authors: Andras-Tovissi Balazs , Kajtar Laszlo , Nyers Jozsef
Published: March 2020

For buildings with ceiling heating and mechanical ventilation, it is extremely important to know the combined effect of the draught and the radiant thermal asymmetry caused by a warm ceiling. There is plenty of literature offering separate descriptions of the dissatisfaction caused by draught and warm ceilings, but research on the combined effect of these two local discomfort factors is incomplete. In order to fill in this gap, human subject measurements were conducted involving 20 subjects, 10 men, and 10 women, who were asked to complete questionnaires on thermal sensation, while being exposed to a random combination of five asymmetries and two draughts. Analyzing the results obtained this way made it possible to evaluate the combined effect of the draught and radiant thermal asymmetry on thermal comfort. The most important outcome of the research is the mathematical description of the expected dissatisfaction rate and the presentation of the differences depending on gender.

Authors: Dewi Anjarsari Intan Ratna
Published: March 2020

Teh Indonesia dikenal karena memiliki kandungan katekin (antioksidan alami) tertinggi di dunia Katekin adalah salah satu turunan dari poliphenol yang memiliki khasiat antioxidant yang tinggi. Faktor yang mempengaruhi kadar katekin adalah varietas dan klon teh,  ketinggian tempat, umur daun, serta jenis petikan.  Dipandang dari sisi kesehatan, makin tinggi katekin berarti makin bermanfaat buat kesehatan. Akan tetapi sebaliknya, ditinjau dari sisi rasa, memiliki perbandingan yang terbalik. Katekin berperan penting di dalam menentukan aroma dan rasa. Katekin merupakan senyawa tidak berwarna dan larut dalam air serta membawa sifat pahit dan sepat pada seduhan teh. Senyawa ini paling penting dalam daun teh karena dapat menentukan kualitas teh dalam pengolahanya. Katekin dalam teh merupakan senyawa kompleks yang tersusun atas epikatekin (EC), epikatekin galat (ECG), epigalokatekin (EGC), epigalokatekin galat (EGCG), dan galokatekin (GC). Komponen yang mendominasi yaitu epigalokatekin dan epigalokatekin galat. Kandungan katekin berkisar antara 20-30% dari seluruh berat kering daun. Dalam pengolahan, secara langsung atau tidak langsung, perubahan katekin selalu dihubungkan dengan semua sifat teh jadi, yaitu rasa, warna, dan aroma. Katekin yang mendominasi 20% berat kering teh merupakan substansi utama yang menyebabkan teh memenuhi persyaratan sebagai minuman fungsional  Kata kunci : katekin, poliphenol, minuman fungsional

Pada kegiatan produksi mangga, tahap pembungaan pada mangga menjadi salah satu penentu dalam produksi buah mangga. Sehingga tahap pembungaan merupakan bagian penting dalam kegiatan produksi. Pembungaan merupakan tahapan pertama dalam kegiatan produksi buah mangga (Mangifera indica L.) di setiap tahun. Perkembangan tanaman khususnya pembungaan bergantung pada beberapa faktor lingkungan dan internal dari tanaman mangga yang diusahakan. Pada daerah subtropis, faktor lingkungan yang mempengaruhi pembungaan ada faktor suhu. Suhu 18°C di siang hari dan 10°C di malam hari memicu perkembangan bunga di daerah tropis. Untuk daerah tropis, faktor suhu tidak sangat mempengaruhi terhadap pembungaan karena perubahan suhu tiap musimnya tidak terlalu tegas. Cekaman kekeringan umumnya dapat memicu pembungaan di daerah tropis. Dalam pembungaan mangga, terdapat adanya rangsangan yang disebut florigenic promoter (FP). Adapun pertumbuhan vegetatif dikendalikan oleh rangsangan induksi berupa vegetative promoter (VP). Fitohormon pun memiliki peran dalam pembungaan mangga. Fitohormon yang berperan dalam pembungaan antara lain auksin, sitokinin, etilen, dan giberelin. Adapun C/N rasio yang meningkat menyebabkan terjadinya peningkatan karbohidrat yang tinggi dan mendukung inisiasi bunga. Adanya akumulasi karbohidrat pada bagian tajuk pada masa vegetatif akhir dapat memicu pembungaan.

Rebung asparagus (Asparagus officionalis L.) termasuk salah satu sayuran yang bernilai ekonomi tinggi di dunia juga di Indonesia. Kultivar asparagus yang ditanam di Indonesia umumnya merupakan kultivar introduksi dari daerah subtropis, sehingga pertumbuhan dan produksinya di Indonesia kurang optimal. Indonesia memiliki suhu dan kelembaban yang cukup tinggi sehingga dapat menyebabkan serangan berbagai penyakit pada tanaman asparagus. Aplikasi larutan garam pada media tanam mampu mengendalikan penyakit akar sehingga asparagus akan tumbuh dengan baik. Percobaan bertujuan mengetahui pengaruh konsentrasi larutan garam dan kultivar asparagus yang cocok untuk dataran medium Jatinangor supaya diperoleh pertumbuhan dan hasil rebung asparagus yang baik. Percobaan dilaksanakan di Laboratorium Kultur Terkendali Fakultas Pertanian Universitas Padjadjaran Jatinangor Kabupaten Sumedang pada ketinggian tempat sekitar 730 mdpl, sejak bulan Januari sampai Juli 2016. Penanaman dilakukan di bawah naungan plastik transparan. Rancangan percobaan menggunakan Rancangan Petak Terbagi (RPT) atau Split-Plot Design dengan dua ulangan. Petak utama adalah kultivar asparagus yang terdiri dari lima taraf yaitu kultivar Atlas F1, De Paoli F1, Jing Green F1, San Knight F1 dan Jaleo. Anak petak adalah konsentrasi larutan garam yang terdiri dari tiga taraf yaitu 1 g/L, 2 g/L dan 3 g/L. Hasil percobaan menunjukkan tidak terdapat hubungan yang saling mempengaruhi antara lima kultivar asparagus dan konsentrasi larutan garam terhadap pertumbuhan, hasil dan kualitas rebung. Pertumbuhan dan kualitas rebung asparagus dari lima kultivar yang di uji tidak berbeda nyata. Kultivar Atlas dan Jaleo mampu  menghasilkan persentase jumlah dan bobot rebung layak pasar lebih tinggi dibandingkan kultivar De Paoli. Perbedaan konsentrasi larutan garam tidak berpengaruh terhadap pertumbuhan, hasil panen dan kualitas rebung. Kata kunci: tinggi tanaman, jumlah batang, bobot brangkasan, bobot rebung, jumlah rebung

El nexo entre literacidad y cultura digital: una mirada docente en Chile
Authors: Thibaut Patricia
Published: March 2020

La revolución digital ha moldeado nuevas prácticas de comunicación y de producción del conocimiento. Desde ahí han surgido conceptualizaciones emergentes sobre literacidad que intentan dar respuesta a la pregunta sobre qué significa estar alfabetizado en un mundo digital. El presente estudio explora dichas problemáticas considerando el enfoque de nuevas literacidades, de modelos culturales docentes y sus prácticas en el día a día. La investigación se sitúa en el contexto educacional chileno y utiliza una metodología de estudio de caso múltiple, la cual se desarrolló en tres establecimientos educacionales durante tres semestres, incluyendo a los profesores de lenguaje y sus estudiantes. El análisis sugiere la existencia de una disonancia entre los modelos culturales de los profesores sobre literacidad y tecnología y sus prácticas docentes. Por lo tanto, las prácticas de enseñanza de lenguaje estarían ancladas en el texto escrito, sin coexistir con nuevas prácticas propias de la cultura digital del siglo XXI.
