The Beginning of History: Japanese and Chinese views of the World
Authors: Turner David
Published: July 2020

The teaching of history is an important way in which the older generation, who control education systems, curricula, content choice and so on, pass on to the younger generation ideas, especially the idea of nationhood, which they hope will form the basis for future national cohesion. The younger generation, however, receive these messages and interpret then through the lens of their own experiences, experiences that they do not share with the older generation. Consequently, the idea of history is re-formed and reformulated by each generation. This paper looks at the role of textbooks, principally history textbooks, in that process. The style of textbooks is to present history as uncontentious, a descriptive account of facts and events. In practice, however, textbooks can only present an arbitrary selection from history, and a crucial decision made by educators is when to start their account – the beginning of history – as this can radically affect the interpretation of events. This facsimile of neutrality stands in sharp contrast to the professional historians’ hope that the teaching of history can develop a critical sense of important and contested events in history. The discussion is illustrated with examples of how history is presented in China and Japan, and how the conflicting accounts serve the interests of the policies adopted by the older generation, but may have unanticipated consequences for the younger generation.

Published: July 2020

This work carries out a numerical investigation on aluminum oxide/de-ionized water nanofluid based shield-free parabolic trough solar collector (PTSC) system to evaluate, validate, and optimize the experimental output data. A numerical model is developed using response surface methodology (RSM) for evaluation (identifying influencing parameters and its level) and single objective approach (SOA) technique of desirability function analysis (DFA) for optimization. The experimental data ensured that global efficiency was enhanced from 61.8% to 67.0% for an increased mass flow rate from 0.02 kg/s to 0.06 kg/s, respectively. The overall deviation between experimental and numerical is only 0.352%. The energy and exergy error is varied from 3.0% to 6.0%, and the uncertainty of the experiment is 3.1%. Based on the desirability function analysis, the maximum and minimum efficiencies are 49.7% and 84.9%, as per the SOA technique. This numerical model explores the way to enhance global efficiency by 26.72%.

Authors: Adeyemi Jerry O. , Onwudiwe Damian C. , Nundkumar Nirasha , Singh Moganavelli
Published: July 2020

Ammonium benzyldithiocarbamate, represented as NH4L, was prepared and used in the complexation reaction involving three organotin(iv) salts, represented as R2SnCl2(R = CH3, C4H9, and C6H5). The structures of the synthesized complexes [(CH3)2SnL2] (1), [(C4H9)2SnL2] (2), and [(C6H5)2SnL2] (3) were established using various spectroscopic techniques (Fourier transform infrared spectroscopy,1H NMR,13C NMR, and119Sn NMR) and elemental analysis. Thermal decomposition of the complexes using thermogravimetric analysis under nitrogen showed no definite pathway in the pattern of the complexes even though they are structurally related. X-ray diffraction studies of the final residue showed a common diffraction pattern for the complexes and confirmed SnS as the product of the thermal treatment. Cytotoxicity studies of these complexes against the human tumor cell lines (HeLa and MCF-7) compared favorably with the used standard 5-fluorouracil drug, with complexes2and3showing very good activity toward the used cell lines.

Published: July 2020

This article focused on the content of lycopene in fresh and dried tomatoes and tomato pomace, as well as in tomato paste at different harvest times (harvest 1 – August and harvest 2 – September). The lycopene content of tomatoes and tomato products was evaluated by using high-performance liquid chromatography (HPLC). The results showed that the highest content of lycopene was estimated in the tomato paste independent of the time of harvest (211.73 mg/100 g dm in August and 184.29 mg/100 g dm in September) and the lowest content in fresh pomace (20.45 and 16.11 mg/100 g dm in August and September, respectively). Good sources of lycopene are tomato by-products, in particularly dried tomato pomace (25.11 mg/100 g dm – harvest 1 and 19.30 mg/100 g dm – harvest 2). This study showed that tomato waste can be considered as a promising source of lycopene for the production of functional foods.

Published: July 2020

Amyloid cascade, one of pathogenic pathways of Alzheimer’s disease (AD), was focused as one of drug discovery targets. In this study, β-secretase (BACE1) inhibitors were designed aiming at the development of multifunctional compounds targeting amyloid pathogenic cascade. Tryptophan was used as a core structure due to its properties of the central nervous system (CNS) penetration and BACE1 inhibition activity. Three amino acid residues and guanidine were selected as linkers to connect the tryptophan core structure and the extended aromatic moieties. The distance between the aromatic systems of the core structure and the extended moieties was kept at the optimal length for amyloid-β (Aβ) peptide binding to inhibit its fibrillation and aggregation. Sixteen designed compounds were evaluated in silico. Eight hit compounds of TSR and TGN series containing serine and guanidine linkers, respectively, were identified and synthesized based on docking results. TSR2 and TGN2 were found to exert strong actions as BACE1 (IC50 24.18 µM and 22.35 µM) and amyloid aggregation inhibitors (IC50 37.06 µM and 36.12 µM). Only TGN2 demonstrated a neuroprotective effect in SH-SY5Y cells by significantly reducing Aβ-induced cell death at a concentration of 2.62 µM. These results support the validity of multifunctional approaches to inhibition of the β-amyloid cascade.

Published: July 2020

Orotic acid, a natural product, is involved in many biological processes. Human mesenchymal stem cells (hMSCs) have the potential of self-renewable and proliferation. They are commonly isolated from the bone marrow aspirates of large bones. The osteogenic potential of these stem cells has been extensively exploited by scientists in the past to evaluate the performance of synthetic scaffolds developed for tissue engineering. In this study, N-arylhydrazone derivatives of orotic acid have been synthesized, and their potential as stimulators of human mesenchymal stem cells has been evaluated. Some of the analogs exhibit well to moderate effect on the proliferation rate.

The integration of quantum well infrared photodetectors with plasmonic cavities has allowed for demonstration of sensitive photodetectors in the mid-infrared up to room-temperature operating conditions. However, clear guidelines for optimizing device structure for these detectors have not been developed. Using simple stripe cavity detectors as a model system, we clarify the fundamental factors that improve photodetector performance. By etching semiconductor material between the stripes, the cavity resonance wavelength was expected to blue-shift, and the electric field was predicted to strongly increase, resulting in higher responsivity than unetched stripe detectors. Contrary to our predictions, etched stripe detectors showed lower responsivities, indicating surface effects at the sidewalls and reduced absorption. Nevertheless, etching led to higher detectivity due to significantly reduced detector dark current. These results suggest that etched structures are the superior photodetector design, and that appropriate sidewall surface treatments could further improve device performance. Finally, through polarization and incidence angle dependence measurements of the stripe detectors, we clarify how the design of previously demonstrated wired patch antennas led to improved device performance. These results are widely applicable for cavity designs over a broad range of wavelengths within the infrared, and can serve as a roadmap for improving next-generation infrared photodetectors.

Published: July 2020

Monolayer transition metal dichalcogenides (TMDs) have emerged as a promising platform for chip-integrated optoelectronics and non-linear optics. Here, we demonstrate a two-dimensional (2D) monolayer tungsten disulfide (WS2) efficiently coupled to a dielectric circular Bragg resonator (CBR). The coupling of the WS2 and CBR leads to pronounced enhancements in both photoluminescence (PL) and second harmonic generation (SHG) by a factor of 34 and 5, respectively. Our work provides a powerful tool to enhance the interactions between light and the 2D materials, paving the way for efficient on-chip optoelectronic devices.
Misalignment resilient diffractive optical networks

Published: July 2020

As an optical machine learning framework, Diffractive Deep Neural Networks (D2NN) take advantage of data-driven training methods used in deep learning to devise light–matter interaction in 3D for performing a desired statistical inference task. Multi-layer optical object recognition platforms designed with this diffractive framework have been shown to generalize to unseen image data achieving, e.g., >98% blind inference accuracy for hand-written digit classification. The multi-layer structure of diffractive networks offers significant advantages in terms of their diffraction efficiency, inference capability and optical signal contrast. However, the use of multiple diffractive layers also brings practical challenges for the fabrication and alignment of these diffractive systems for accurate optical inference. Here, we introduce and experimentally demonstrate a new training scheme that significantly increases the robustness of diffractive networks against 3D misalignments and fabrication tolerances in the physical implementation of a trained diffractive network. By modeling the undesired layer-to-layer misalignments in 3D as continuous random variables in the optical forward model, diffractive networks are trained to maintain their inference accuracy over a large range of misalignments; we term this diffractive network design as vaccinated D2NN (v-D2NN). We further extend this vaccination strategy to the training of diffractive networks that use differential detectors at the output plane as well as to jointly-trained hybrid (optical-electronic) networks to reveal that all of these diffractive designs improve their resilience to misalignments by taking into account possible 3D fabrication variations and displacements during their training phase.

Published: July 2020

During the Early Neolithic in the Near East, particularly from the mid ninth millennium cal BC onwards, human iconography became more widespread. Explanations for this development, however, remain elusive. This article presents a unique assemblage of flint artefacts from the Middle Pre-Pottery Neolithic B (eighth millennium BC) site of Kharaysin in Jordan. Contextual, morphological, statistical and use-wear analyses of these artefacts suggest that they are not tools but rather human figurines. Their close association with burial contexts suggests that they were manufactured and discarded during mortuary rituals and remembrance ceremonies that included the extraction, manipulation and redeposition of human remains.
Cryogenic and Aging Treatment Effects on the Mechanical Properties of Ti-15V-3Al-3Cr-3Sn Titanium Alloy
Authors: Yumak Nihal , Aslantaş Kubilay , Çetkin Ahmet
Published: July 2020

In this study, single and duplex aging treatment was applied to the metastable beta titanium alloy of titanium-15 vanadium-3 aluminum-3 chromium-3 tin with cryogenic treatment. The single-step aging treatment was applied for 20 h at 450°C and 10 h at 550°C. The cryogenic treatment was carried out at −196°C for 24 h, followed by single-step or duplex aging treatment. The results obtained show that the cryogenic treatment causes the formation of martensitic alpha phases. Following the cryogenic treatment, martensitic alpha phases were observed in the sample, which was subjected to aging treatment at 450°C for 20 h, whereas these phases disappeared completely in the sample treated at 550°C for 10 h. Preaging treatment applied after cryogenic treatment prevented the formation of precipitate-free zones by providing a finer and uniform distribution of α phases. Cryogenic treatment followed by preaging treatment at 250°C for 24 h led to the formation of dense metastable prephases. This resulted in a 10% increase in tensile strength, 4% elongation, and 5% hardness compared to preaging at 300°C for 10 h after cryogenic treatment. The optimum mechanical properties in single-step sample groups were obtained in samples aged 20 h at 450°C. In duplex-aged samples, optimum mechanical properties were obtained in cryogenic treatment followed by 250°C/10 h + 450°C/20 h duplex aging treatment.

In recent years, improved sequencing technology and computational tools have made de novo genome assembly more accessible. Many approaches, however, generate either an unphased or only partially resolved representation of a diploid genome, in which polymorphisms are detected but not assigned to one or the other of the homologous chromosomes. Yet chromosomal phase information is invaluable for the understanding of phenotypic trait inheritance in the cases of compound heterozygosity, allele-specific expression or cis-acting variants. Here we use a combination of tools and sequencing technologies to generate a de novo diploid assembly of the human primary cell line WI-38. First, data from PacBio single molecule sequencing and Bionano Genomics optical mapping were combined to generate an unphased assembly. Next, 10x Genomics linked reads were combined with the hybrid assembly to generate a partially phased assembly. Lastly, we developed and optimized methods to use short-read (Illumina) sequencing of flow cytometry-sorted metaphase chromosomes to provide phase information. The final genome assembly was almost fully (94%) phased with the addition of approximately 2.5-fold coverage of Illumina data from the sequenced metaphase chromosomes. The diploid nature of the final de novo genome assembly improved the resolution of structural variants between the WI-38 genome and the human reference genome. The phased WI-38 sequence data are available for browsing and download at wi38.research.calicolabs.com. Our work shows that assembling a completely phased diploid genome de novo from the DNA of a single individual is now readily achievable.

Profilaktyka zakażeń u wcześniaków i noworodków – jaki antyseptyk wybrać?
Authors: Oleksy-Wawrzyniak Monika , Brożyna Malwina , Piątkowska Elżbieta , Niewińska Kinga , Bartoszewicz Marzenna
Published: July 2020

Noworodki urodzone przed ukończonym 37. tygodniem ciąży klasyfikuje się jako wcześniaki. Wcześniactwo często związane jest z niską masą urodzeniową dzieci, tj. wagą poniżej 2500 g, i stanowi najczęstszą przyczynę śmierci niemowląt w pierwszym miesiącu życia oraz drugą najczęstszą przyczynę zgonów dzieci poniżej 5. roku życia. U około 20% noworodków i niemowląt z bardzo niską masą urodzeniową występują infekcje układowe, z czego przyczyną ponad połowy zgonów jest sepsa. Ze względu na czas wystąpienia zakażenia wyróżnia się sepsę wczesną (do 72 godzin po urodzeniu) i późną. W Polsce najczęściej izolowanymi patogenami w zakażeniach krwi u noworodków są: S. agalactiae, E. coli, K. pneumoniae, Enterobacter sp., A. baumannii, gronkowce koagulazo-ujemne i C. albicans; rzadziej – S. aureus, H. influenzae i L. monocytogenes. Skuteczna dezynfekcja skóry za pomocą miejscowo działających środków przeciwdrobnoustrojowych stanowi istotny czynnik prewencyjny w ograniczaniu występowania zakażeń szpitalnych u wcześniaków. Jednak ze względu na niedojrzałość powłok skórnych u tej grupy pacjentów oraz ryzyko powikłań, decyzja o wyborze właściwego preparatu, w świetle braku oficjalnych wytycznych, jest często trudna. Stosowanie u wcześniaków powidonu jodu zwiększa ryzyko wystąpienia niedoczynności tarczycy. Chlorheksydyna i oktenidyna mogą powodować podrażnienia skóry z oparzeniami włącznie, antyseptyki alkoholowe natomiast mogą działać neurotoksycznie. Najbezpieczniejszym i najskuteczniejszym antyseptykiem – zarówno u noworodków przedwcześnie urodzonych, jak i z niską masą urodzeniową – na chwilę obecną wydaje się być poliheksanidyna z betainą.

Published: July 2020

Machine learning is a way to study the algorithm and statistical model that is used by computer to perform a specific task through pattern and deduction [1]. It builds a mathematical model from a sample data which may come under either supervised or unsupervised learning. It is closely
related to computational statistics which is an interface between statistics and computer science. Also, linear algebra and probability theory are two tools of mathematics which form the basis of machine learning. In general, statistics is a science concerned with collecting, analysing, interpreting
the data. Data are the facts and figure that can be classified as either quantitative or qualitative. From the given set of data, we can predict the expected observation, difference between the outcome of two observations and how data look like which can help in better decision making process
[2]. Descriptive and inferential statistics are the two methods of data analysis. Descriptive statistics summarize the raw data into information through which common expectation and variation of data can be taken. It also provides graphical methods that can be used to visualize the sample
of data and qualitative understanding of observation whereas inferential statistics refers to drawing conclusions from data. Inferences are made under the framework of probability theory. So, understanding of data and interpretation of result are two important aspects of machine learning.
In this paper, we have reviewed the different methods of ML, mathematics behind ML, its application in day to day life and future aspects.

We have stepped into a world of undeniable data breach fatigues. Thus to ensure data security, encryption schemes come into action, one such highly talked about encryption nowadays is “Homomorphic Encryption” which is mainly used to compress data for their easy storage involving
secure transmission and processing on cloud without compromising on privacy since special keys are needed for primary encryption and final decryption. Homomorphic encryption allows operation on two ciphertexts to give an encrypted (coded) result which when decrypted (decoded) maps to result
of the operation, if it would have been on plaintext. It can be either multiplicative like the RSA or additive like the Pallier cryptosystem. Here we also focused on ideal lattice based public key encryption scheme which is almost bootstrappable. Multihop homomorphic encryption also has vital
roles to play here. A strong homomorphic encryption is one which is resistant to all attacks using various algorithms. Thus our main objective is to allow encrypted computing on data, minimize memory usage and to save energy and time. Our presentation will try to focus on the researches done
so far and also on the success rates of the scheme which is affecting the real world.

convenience to characters, it also exposes many security issues. In recent years, information security incidents such as information leakage, SQL injection vulnerabilities, network penetration, and hacking attacks have triggered irreparable losses to enterprises, society, and individuals.
In our paper, a symmetric key encryption with fuzzy based session key has been proposed for satisfying the key issues like security; increase the strength of symmetric key. Here the session key is generated using fuzzy logic. Now the encryption is done by using this session key and symmetric
key. Here a new authentication scheme is developed to generate cipher text. Different types of experiments to test the robustness of keys and encryption technique and comparative study with existing standard techniques have been done with satisfactory results. This paper has taken steps to
develop an attack capability for use within a cyber challenge environment. The principles discussed within this paper aim to be applicable to all challenges against mathematical cryptanalysis and cryptographic protocol in general and also it is used to cover threat modeling, construction of
cyber security test beds and take footsteps against offensive cyber operations.

Authors: Sarkar Mrinmoy , Kumar Asok , Maji Bansibadan
Published: July 2020

Fifth generation systems are required to fulfill the objectives like compatibility, flexibility, high speed data rate and low cost. Universal Mobile Telecommunication System (UMTS) use WCDMA as the air interface for 4th generation mobile system. The performance of wireless communication
system is often limited by the radio channel models. In urban areas, channel is modeled as Rayleigh fading channel. This channel causes multipath channels and other problems resulting degraded performance. Hence, channel estimation before receiver helps to receive the transmitted signal using
rake receiver. Rake receiver is a conventional receiver for DS-CDMA system. In this, channel is estimated adaptively using LMS algorithm and performance of this algorithm is studied for various multipath channels and step sizes. Moreover, the channel introduces Inter Symbol Interference (ISI)
and channel equalizers are used to compensate for the ISI. In this work, BER vs. SNR performance of Zero Forcing Equalizer (ZFE), Minimum Mean Square Error (MMSE) and MMSE- Decision Feedback Equalizer (MMSE-DFE) in WCDMA downlink system are compared with conventional rake receiver for various
spread factors in Rayleigh multipath fading channel with Additive White Gaussian Noise.

HUMAN INTELLIGENCE OPERATED BY INNATE SIGN REFLEX LOGIC OF DICHOTOMY AND DUALISM AND POST-NATALLY ACQUIRED LOGIC OF “GROUP” AND “FORWARD ERROR CORRECTION (FEC)” - DIGITAL LINGUISTICS
Authors: Kumon Tokumaru
Published: July 2020

It is plausible that language is processed by the innate spinal sign reflex mechanism. Human speech sound contains logical properties of phoneme and mora, which interact with in-brain antigen/antibody molecular structures and networking memories in the postnatally developed logical
circuits optimized for signals of syllables, a character set (long lasting syllables) and electronic form (interactive and ubiquitous syllables). For grammatical decoding, sound localization function at the brainstem auditory nuclei is converted to process sound vectors of grammatical syllables.
For axiomatic scientific concepts, sign reflex logic of “If A then B” must be upgraded by mathematical group logic to be acquired by learning, so that the results of interdisciplinary conceptual operations should become meaningful and productive. As electronic data is interactive,
we can discover as many relevant linguistic information as possible with keyword search on the internet within a few seconds. As a result, we obtain multi-disciplinary and voluminous linguistic information but with uncertain reliability. To inherit collective human intelligence and correct
any errors in linguistic information of the past, regenerative reading might be appropriate for individual ontogenesis to repeat intellectual and conceptual phylogeny. Errors cannot be corrected by the original authors posthumously but only by those who are alive now and equipped with error
correction techniques for linguistic information.

This paper deals with concise study on the applications of data-structure and algorithms associated with field of computer science. It has huge significance in the proper functioning of operating system and improvement of the throughput by resource utilization. There is an amount of
essential complexity in the operations related to the data and files present in computer system. No brute-force approaches can minimize and manifest it so easily by adopting to the non-harmonized methodology of the storage and management, but it can be placed so that it doesn’t get in
the way and it’s also easy to understand. The best such place is a data structure. Data structures have many applications in the area of system development, data base design, software coding and computer-networks. In this paper, we have presented a succinct explanation about the efficiency
and application of algorithms upon different domains followed by a survey of different areas.

ABSTRACT Objectives: to analyze the health vulnerability of young female transgender living with HIV/AIDS. Methods: qualitative, descriptive, and exploratory study, based on the theoretical reference of Social Representation and concept of vulnerability; developed with six transgender women in a reference Hospital for HIV/AIDS. We analyzed the individual interviews, recorded, and transcribed in full, in the IRaMuTeQ software by Similitude Analysis. Results: the thematic categories are listed based on the Ayres reference: 1) Individual dimension of vulnerability to HIV/AIDS; 2) Social dimension of vulnerability to HIV/AIDS; 3) Programmatic dimension of the vulnerability. Final Considerations: the young female transsexual living with HIV/AIDS experience a context of vulnerability in health associated with a lack of knowledge and difficulties for the realization of self-care. The study evidenced the representations of social abjection and unpreparedness of the health team that compose the Primary Attention in Health in promoting qualified assistance for the execution of the effective and humanized care.

Abstract Models for estimating leaf area of bananas found in the literature are not suitable for lanceolate type leaves occurring at the vegetative stage of ratoon suckers dependent of mother plant. The objective was to determine equations for estimating the leaf area of ‘Prata-Anã’ and ‘BRS Platina’ banana plants with lanceolate type leaves. 212 and 164 lanceolate type leaves having 10 cm-wide lamina or less were collected from ‘Prata-Anã’ and ‘BRS Platina’ banana plants of 90 days of age or less, respectively. Width (W), length (L), width/length ratio (WLR), and scanner-measured leaf area (LAscanner) were determined. Using the backward elimination procedure, simple and multiple linear regression equations were fitted to the relationship between leaf dimensions (W, L and WLR) and LAscanner. To evaluate how precise the equations are in predicting leaf area (LApredicted), Pearson correlation coefficients were calculated between LA and LApredictedscanner. The models highly correlated with LAscanner at 1% of significance level. The models are and LALL() = Prata-Anã = - 0,0133624 + 0,000489859**L - 0,00183182 **W and LALL(Platina) 0,00237026 + 0,004781**W - 0,096802** WLR.
Persistência e Abrangência dos Eventos Extremos de Precipitação no Sul do Brasil: Variabilidade Espacial e Padrões Atmosféricos

Published: July 2020

Resumo A região Sul do Brasil em função de sua localização geográfica é caracterizada pela diversidade de sistemas meteorológicos que atuam o ano inteiro, resultando em condições adversas de tempo. Este trabalho analisa os eventos extremos de precipitação caracterizando-os conforme sua persistência e abrangência, e os padrões atmosféricos relacionados. O desenvolvimento de um algoritmo computacional permitiu a identificação e conhecimento da abrangência espacial dos eventos extremos de precipitação, os quais foram classificados em caráter abrangente e não-abrangente, resultando quatro grupos de chuvas identificados conforme os critérios de intensidade, persistência e abrangência. Os resultados mostraram que o verão é a estação preferencial para ocorrência de eventos extremos em todas categorias analisadas e um maior número de eventos ocorre entre o norte do Rio Grande do Sul e o Paraná, e para os casos de Chuva Persistente o litoral de Santa Catarina se mostra uma região favorável a este tipo de evento. Entre os principais processos atmosféricos para ocorrência de eventos extremos com caráter abrangente são a disponibilidade de umidade nas camadas mais baixas da troposfera, juntamente com o jato de altos níveis e um cavado em médios níveis.
“Sua Majestade, o perverso”: domínio e onipotência nas perversões
Authors: Vale André Luiz Alexandre do , Cardoso Marta Rezende
Published: July 2020

Resumo Este artigo pretende explorar as bases narcísicas da perversão para mostrar que a problemática perversa tem em seu fundamento um ego narcisicamente ferido, que precisa manter-se ilusoriamente unificado, afirmando-se em sua onipotência infantil. Na base do funcionamento narcísico dos sujeitos perversos, reside um objeto interno “indomável”, de modo que toda manobra do perverso se configura como movimento extremo para dominá-lo e exercer o controle onipotente sobre ele. Diante da impossibilidade de se dominar internamente este objeto “encravado”, o sujeito acaba por tentar exercer o domínio ativo do objeto externo, tornado sua presa, seu cúmplice.
Las creencias parentales en el proceso de crianza y sus relaciones con el comportamiento adolescente
Authors: Morales-Castillo Miguel
Published: July 2020

Resumen Las creencias parentales están integradas estructuralmente en la relación entre padres e hijos y pueden ser consideradas como contribuciones para comprender el desarrollo adolescente. El presente trabajo busca analizar los vínculos entre las creencias parentales y el comportamiento adolescente, para ello se desarrolló una revisión bibliográfica en seis bases de datos, que incluyó 53 estudios en donde se dimensiona la influencia de las creencias parentales en la crianza con adolescentes. En el análisis de datos, se destacaron como “creencias parentales” los siguientes conceptos: las creencias generales sobre los atributos y las experiencias humanas, las expectativas parentales, las percepciones sobre las capacidades de los hijos, los valores y metas parentales, la autoeficacia parental y las creencias sobre el control de las situaciones. Se concluye que las creencias parentales son afectadas por los atributos y las experiencias de los padres, lo que influye en un efecto de cascada sobre el comportamiento adolescente.

Abstract: Despite an increase in studies involving lycophytes and ferns in recent years, Maranhão is still one of the northeastern states with a poorly known flora, mainly due to low sampling. For Chapada das Mesas National Park, a protected conservation unit in the Cerrado maranhense with phytophysiognomies that favor floristic diversity, there are no floristic studies about lycophytes. This study aimed to conduct the floristic inventory and taxonomic study of lycophytes in Chapada das Mesas National Park. Three collection expeditions, of three days each, were made between March 2017 and June 2018. Three families of lycophytes represented by three genera and six species were identified in the study area. The most diverse family was Selaginellaceae with four species: Selaginella conduplicata, S. erythropus (Mart.) Spring, S. radiata (Aubl.) Baker and S. simplex Baker. The other two families, Isoëtaceae and Lycopodiaceae, had one species each, Isoëtes sp. and Palhinhaea cernua (L.) Franco & Vasc. This study also reports two new record for the Brazilian Cerrado phytogeographic domain, S. conduplicate and S. radiata, of which the first is a new record for Maranhão State. Most specimens were found in riparian forest on rocky outcrops.

ABSTRACT The objective was to evaluate animal performance and nutritional characteristics of Brachiaria brizantha cv. BRS Piatã in two integrated systems, during the summer and winter, five years after the initial establishment of the area. The randomized block experimental design was adopted with treatments consisting of a control (five native trees per hectare) and an integrated crop-livestock-forestry (ICLF) system with 227 eucalyptus trees per hectare. Animal performance, canopy height, soil cover, forage mass (leaf, stem and senescent material), and forage nutritive value were evaluated. Differences between systems were observed in forage mass (total, leaf, stem and senescent material), soil cover and forage nutritive value in both seasons. Shading conditions provided by eucalyptus in the ICLF system lead to a reduction in forage mass and neutral detergent fiber content, and to an increase in crude protein and in vitro organic matter digestibility. However, no effect on animal performance was obtained. The presence of trees improves the forage nutritive value without impacting animal performance in integrated systems.

Authors: Kudacheva N.A.
Published: July 2020

ABSTRACT Papillomatosis is one of the few diseases in which autovaccine therapy is recommended, especially in the case of mass manifestation in animals. It is noted that papillomas are diagnosed in 15.7% of cases in histological diagnosis of oncological diseases. Therefore, this work studied the profile of oncological diseases in dogs and the clinical effectiveness of autovaccine therapy of papillomatosis. The article gives a morphological description of papillomas used as a biomaterial, and also describes the technological methods of manufacturing an autovaccine used to treat animals against papillomatosis. A therapeutic scheme for administering the vaccine was proposed and tested, and the results of the clinical trial are presented, as well as a reflection on some moments of the mechanism of vaccine therapy for papillomatosis.
