Tujuan penelitian untuk mengetahui (1) pengaruh penambahan Fe3O4 terhadap mikrostruktur pada PANI/Ag/Fe3O4 (2) pengaruh Fe3O4 terhadap konduktivitas film PANI/Ag-Fe3O4 (3) pengaruh Fe3O4 terhadap sifat magneto elektrik PANI/Ag/Fe3O4 (4) pengaruh Fe3O4 terhadap sifat elektro optik PANI-Ag-Fe3O4. Nanokomposit PANI-Ag-Fe3O4 telah diteliti sebagai aplikasi devais elektronik, dimana PANI menjadi pilihan karena ramah lingkungan, stabil dan potensi aplikasi yang menjanjikan. Dalam penelitian ini PANI berperan sebagai matriks, Ag sebagai katalis meningkatkan konduktivitas PANI dan Fe3O4 sebagai pengaruh sifat kemagnetan. PANI/Ag/Fe3O4 disintesis menggunakan metode polimerasi kimia untuk menambahkan doping Ag pada PANI dan metode kopresipitasi pada Fe3O4 untuk variasi komposit pada PANI. Gugus fungsi dari sampel yang diperoleh dikarakterisasi menggunakan FTIR, kristalinitas dan fase yang terbentuk hasil karakterisasi XRD, mikrostrutur sampel hasil karakterisasi dari SEM. Konduktivitas PANI/Ag/Fe3O4 diketahui dari pengukuran 4 probe sedangkan sifat magneto elektrik dan elektro optik merupakan pengembangan dari konduktivitas sebanding dengan medan magnet dan intensitas cahaya yang diberikan pada sampel. Hasil penelitian menunjukkan terdapat fase Fe2O3 akibat Fe3O4 teroksidasi saat protonasi AgNO3 pada perlakuan sonikasi. Doping Ag meningkatkan konduktivitas namun seiring penambahan Fe3O4 ditingkatkan dan medan magnet yang diterapkan menyebabkan sifat magneto elektrik menurun dari 20.414-2.42 S/cm. Fe3O4 tidak mempengaruhi pembentukan struktur kristal tetapi mempengaruhi mikrostruktur dari sampel PANI/Ag/Fe3O4. Sifat elektro optik mengalami peningkatan seiring intensitas cahaya yang diberikan berkisar 20.414 S/cm sampai 31.84 S/cm.

Published: January 2022

The recognition of handwritten Bangla digit is providing significant progress on optical character recognition (OCR). It is a very critical task due to the similar pattern and alignment of handwriting digits. With the progress of modern research on optical character recognition, it is reducing the complexity of the classification task by several methods, a few problems encounter during recognition and wait to be solved with simpler methods. The modern emerging field of artificial intelligence is the Deep Neural Network, which promises a solid solution to these few handwritten recognition problems. This paper proposed a fine regulated deep neural network (FRDNN) for the handwritten numeric character recognition problem that uses convolutional neural network (CNN) models with regularization parameters which makes the model generalized by preventing the overfitting. This paper applied Traditional Deep Neural Network (TDNN) and Fine regulated deep neural network (FRDNN) models with a similar layer experienced on BanglaLekha-Isolated databases and the classification accuracies for the two models were 96.25% and 96.99%, respectively over 100 epochs. The network performance of the FRDNN model on the BanglaLekha-Isolated digit dataset was more robust and accurate than the TDNN model and depend on experimentation. Our proposed method is obtained a good recognition accuracy compared with other existing available methods.

Authors: Mir Javaid Ahmad , Rashid Nadiya
Published: January 2022

A newborn baby has only three demands. They are warmth in the arms of his mother, food from her breasts and security in the knowledge of her presence. Breastfeeding satisfies all three. While breastfeeding may not seem the right choice for every parent, it is the choice for every baby because it fulfills the physical needs as well as psychotic complementary of the child.

The study aimedto find out the association of nipple soreness in experimental group and comparison group in terms of sample characteristics of postnatal mothers.

A quasi experimental study was conducted on 70 postnatal mothers, (35 in experimental group and 35 in the comparison group) who breast feeds their babies were selected conveniently. Feeding pattern was assessed by LATCH scale four times in a day followed by the application of hind milk minimum four times in a day for three or four days as per discharge day of mother. The mother was asked to rub hind milk on nipples after feeding the baby and letting it air dry in front of researcher and nipple soreness scale was used to check the sore nipple at third and fifth day or at the day of discharge. Follow up of postnatal mothers was done telephonically by using interview questionnaire on day 15 in both groups.

Study findings revealed that on 3rd day, the mean nipple soreness score was higher in comparison group (1.45) than experimental group (0.10) and thus there was significant difference (t value = 3.87) in nipple soreness score.

Study concluded that breast milk application was effective in preventing sore nipples among postnatal mothers. Hence, it can be recommended to use breast milk for the prevention of sore nipple.

Authors: Uzma Ashraf Mir , Choudhary Priyanka
Published: January 2022

Children facing life with chronic illness and disability are increasing in number. There are multiple factors which are responsible for that. Most of the children survive well into adulthood with early intervention, treatment and care. Pediatric nurses may create excellent professional roles caring for children with special health care needs and their families. The main responsibility will be to provide the children medical care and developmental training so that they can handle basic daily functions and lead happy, healthy lives. The role of a pediatric nurse in this field is not fixed. They may have to carry out different kinds of responsibilities based on the type and extent of special need.

Pediatric nurses are responsible for helping children adapt to a hospital setting and prepare them for medical treatment and procedures. These nurses have special training to provide expert care to the child with special needs while working with the family to address their concerns, problems and help them to understand different treatment options and services available for the child with special needs.

Pediatric nurses not only focus on the child with special needs but involve themselves in the wellbeing of other family members. They have special training in caring of children, good interacting skills, good empathy, immense love for children, flexibility, having control over their own emotions and stress management skills.

El presente documento busca ser una guía para el diseño de transferencias monetarias condicionadas. La situación educativa de los jóvenes más vulnerables en Honduras y El Salvador ha empeorado debido a la crisis sanitaria del COVID-19, incrementando los niveles de inasistencia y deserción, principalmente por la falta de recursos económicos de las familias lo que ha obligado a muchos jóvenes a dejar de estudiar para poder apoyar a la economía familiar o debido al cierre de escuelas muchos se relacionaron con prácticas ilícitas como son las pandillas. Así, como mecanismo de protección de las trayectorias educativas se ha pensado en diseñar intervenciones de transferencias monetarias condicionadas que levanten las barreras económicas de los jóvenes más vulnerables así como intervenciones de transferencias de información que ayude a la sensibilización de los jóvenes al relacionamiento de prácticas ilícitas. El documento buscar guiar paso a paso y de manera práctica en el mecanismos de la selección de la población objetivo, los elementos más importantes de las intervenciones de transferencias condicionada, los mecanismos de gestión para la implementación, la evaluación y monitoreo; y el presupuesto.

This edition reviews the long-term performance of economic growth and productivity in the region. It then draws on research from the Inter-American Development Banks Connectivity, Markets, and Finance Division that estimates how much investment in digital infrastructure is needed for countries across Latin America and the Caribbean to reach the levels of advanced economies. This research also estimates both the potential economic benefits associated with that investment and its costs, highlighting the potentially large multipliers associated with closing digital infrastructure gaps. The highlights of the analysis are as follows. It is estimated that closing the digital access gap between Caribbean economies and members countries of the Organization for Economic Co-operation and Development (OECD) could potentially increase the regions GDP by about 6 to 12 percent over the medium term, depending on the country. These gains are multiples of the estimated costs, ranging from about 2 times to nearly 50 times those estimated costs. Productivity gains represent about 80 percent of the estimated improvements in GDP. As is typical with the Caribbean Quarterly Bulletin, the Regional Overview is followed by country sections that provide more detailed analysis for each of the countries covered.

The paper shows the demand of the chemical industry for corrosion-resistant materials, as well as the prospects of the creation of laminated metal materials with internal protectors (LMM with IP). The authors offer the architecture and composition of layers of LMM with IP ensuring stable operation within the highly aggressive environment. The study identified the possibility of improving corrosion resistance ten and more times compared to high-alloy austenitic stainless steels. The authors show the efficiency of the application of explosion welding to produce LMM with IP. The paper considers the example of the production of a four-layer material with one internal protector made of low-alloyed, low-carbon steel of the following architecture: 2-mm layers of 12H18N10T + 09G2S + 12H18N10T plates of steel and the base 10-mm layer of 09G2S. The authors developed the process diagrams for performing butt-welded joints of such material, identified special aspects of the formation of its microstructure and properties. To obtain the maps of specific chemical elements distribution in the layers and interlayer boundaries, the authors used the energy-dispersive microanalysis method. Peculiarities of corrosion damage of a welded seam and weld-adjacent area are studied. The study showed the necessity of using a facing layer in a welded seam. Microstructural, X-ray tomographic, and gravity-measuring studies proved the obtained results. To evaluate the quality of welded joint, the authors performed the corrosion tests of a welded seam and weld-adjacent area, carried out visual inspection control and X-ray tomography. The corrosion tests were carried out using 10-% III ferrous chloride water solution. The paper presents the results of the static bending tests of a welded joint. The absence of fracture, lamination, and cracks served as an estimation criterion. The study identified the possibility of obtaining a defect-free welded joint of LMM with IP with high corrosion resistance and advanced mechanical properties.

Friction treatment is an effective method to increase the strength and wear resistance of austenitic chromium-nickel steels. Previously, the authors identified that the high level of mechanical properties of metastable austenitic steels is achieved at the intensive development of deformation γ→α'-transformation. However, the presence of deformation martensite in the austenitic steel structure can negatively affect its anti-corrosion properties. The search for ways to improve the strength characteristics of stable austenitic chromium-nickel steel while maintaining high resistance to corrosion destruction is the up-to-date line of research. In this paper, to evaluate the mechanical properties of 03Cr16Ni14Mo3Ti steel in the hardened condition and after friction treatment, the authors applied the technique of measuring the hardness using the restored print and the method of instrumental micro-indentation, which allows recording the indenter loading and unloading diagrams. The corrosion failure resistance of steel was studied in general corrosion tests. The authors compared the corrosion rate of austenitic steel after grinding, electropolishing, and friction treatment; using scanning electron microscopy and optical profilometry, studied steel surfaces subjected to these treatments and determined their roughness. Nanostructuring friction treatment provides surface hardening of stable austenitic steel up to 570 HV 0.025. The study showed the high efficiency of friction treatment application to increase the strength characteristics and resistance of steel surface layer to elastic and plastic deformation. The authors identified that austenitic steel is characterized by similar corrosion rates km=(3.26–3.27)∙105 (g/cm2∙h) after electrolytic polishing (the structure of large-crystal austenite) and after frictional treatment (sub-micro/nanocrystalline austenite structure), while mechanical grinding leads to a twofold increase in the corrosion rate of 03Cr16Ni14Mo3Ti steel due to the occurrence of microcracks and metal breakouts on the polished surface. The research justified the determining role of the quality of the surface formed by various treatments (roughness, the presence of continuity defects) in ensuring the corrosion resistance of stainless steel.

The study aims to analyze the University Social Responsibility (USR) policy implemented at the Michoacan State University (Universidad Michoacana de San Nicolás de Hidalgo - UMSNH) from the perspective of the university community. For that purpose, a Structural Equations Model in its variant of Partial Least Squares (PLS) was used from a theoretical/empirical construct on the USR. Five variables integrated into 17 indicators were used, obtained by a representative sample. The results are presented in two sections; a) USR performance at the UMSNH and; b) the role of each variable in the PLS model. It is concluded that the performance was regular and the Internal Management (IM) had a key impact on the model operation. In the management practice, this might help identify areas to improve the performance of this policy by sector and variables.

Published: January 2022

This article explores the potential of dialogue networks as tools for valuing rural women and overcoming the traditional marginalization of rural women in the countryside. The guiding hypothesis is that when given opportunities to co-produce solutions in a participatory manner and an enabling environment, women can articulate and express their challenges and visualize desirable futures. The results confirm this hypothesis to the extent that women experience and execute these premises in the established spaces of dialogue. The recommendations are for the promotion of actions and policies that provide environments in which women can reframe their role in society and the family.
