Authors: Rahamath Kashifa , Dev Bhawna , P.M Venkata Sai
Published: May 2021

BACKGROUND Lobular breast carcinomas have always been a diagnostic challenge, over the years, to the radiologist. They are one of the most commonly missed lesions on breast cancer screening checks, due to their varied presentation. We wanted to provide a concise and practical approach to characterise their morphology and presentation on mammography and ultrasound. METHODS A retrospective study was done for four years and a total of 699 patients with histopathologically proven breast cancer were chosen. Those patients with invasive lobular carcinoma (N = 56) and invasive ductal carcinoma (N = 538) were segregated and 50 cases from each group were selected randomly. RESULTS On mammography, an irregular, high-density mass was the most common presentation of both lobular (68 %) and ductal (86 %) carcinomas. Presentation as focal asymmetry (28 %) was significantly more prevalent in lobular breast carcinomas. Sonographically, an architectural distortion (30 %) and non-parallel orientation (28 %) was predominantly seen in invasive lobular carcinomas (ILCs). Mass (88 %) with micro lobulated (34 %) or angular (22 %) margins was more in favour of ductal carcinoma. Other general parameters like age at presentation, positive family history, multifocality, bilaterality, tumour size and lymph nodal involvement were not significantly different between both the groups. CONCLUSIONS A careful analysis of digital breast tomosynthesis and ultrasonography, keeping in mind all the clear differentiating features, along with experience in the field, will dramatically increase the early detection of lobular breast cancers.

Published: May 2021

BACKGROUND Hyperglycaemia is the main cause for diabetes related complications. Though a number of factors add to the blood glucose, it is broadly known that proper selfmanagement activities reduce the risk in diabetic patients. This study was conducted to assess the self-care activities and their adherence amongst the diabetic patients attending the RHTC, IIMSR Lucknow. METHODS This cross-sectional study involved 92 previously diagnosed diabetic patients attending the outpatient department of rural health training centre, Integral Institute of Medical Sciences and Research, Lucknow, from December 2017 to August 2018. Data was collected by personal interviews using diabetes self-management questionnaire (DSMQ). SPSS software version 16.0 was used for data analysis. RESULTS All patients were aged between 40 to 65 years and males were higher in proportion (56.0 %). About 96.3 % subjects took diabetes medication as prescribed and 88.9 % subjects recorded their blood sugar levels regularly. Nearly 77.8 % did consistent exercise to accomplish optimal blood sugar stages & 96.3 percent took the dietary advice given by investigator. About two-third patients avoided physical activity although they knew that it would improve their diabetes goal. About one third patients forgot or skipped their diabetes medication. The subscales of health-care use showed negative average intra class correlation. Mean score of subscale glucose management was maximum as compared to other subscales. CONCLUSIONS This study provides evidence that the DSMQ enables an efficient assessment of selfcare activities and their adherence among diabetes patients. Adherence to the treatment of diabetes and lifestyle modifications is the need of the hour. KEY WORDS DSMQ, Diabetes, Self-Care Activities, Cross-Sectional, Intra Class Correlation
Effect of Periodontal Inflammation on Haematological and Liver Function Parameters - A Comparative Clinical Study from Uttar Pradesh, India
Authors: Singh Kuldeep , Kanaujia Alka , Singh Savita
Published: May 2021

BACKGROUND Periodontitis is an inflammatory disease of periodontium. The inflamed and ulcerated epithelium allows the entry of oral microorganisms, bacterial endotoxins, proinflammatory immune mediators, like Interleukin -1 (IL-1), Interleukin-6 (IL-6), tumour necrosis factor (TNF-α) and prostaglandin E2 (PGE2) into the systemic circulation, which may produce systemic effects. The present study was conducted to evaluate the effect of periodontal inflammation on haematological and liver function parameters. METHODS The clinical study was conducted among 30 patients with periodontal inflammation. Clinical parameters [plaque index (PI), gingival index (GI), probing pocket depth (PPD)], haematological [RBC count, haemoglobin (Hb) concentration, total leukocyte count and differential leukocyte count] and liver function parameters [alanine aminotransferase (ALT), aspartate aminotransferase (AST) & alkaline phosphatase (ALP)] were recorded at baseline and after 1 month of scaling and root planning (SRP). RESULTS There was significant improvement in clinical parameters (P-value < 0.001), haematological parameters (P-value < 0.001), except eosinophils (P = 0.303) and basophils (P = 0.860). Changes in liver function test (LFT) parameters were found to be significant (P < 0.05) after SRP. CONCLUSIONS There is an association between periodontal inflammation and systemic parameters. KEY WORDS Periodontal Inflammation, Haematological, LFT.
A Study of Effect of Glycaemic Status on Pulmonary Function Test in Type 2 Diabetes Mellitus
Authors: G.T Basavaraj , Indikar Mudassir , Negali Malingaraya
Published: May 2021

BACKGROUND Diabetes mellitus is a metabolic disorder precipitating micro vascular, macro vascular complications and peripheral vascular diseases. Pulmonary complications of diabetes mellitus have been poorly characterised. Glycaemic status has shown varied impact on lung functions. In type-2 diabetes there is resistance to insulin action and also inadequate insulin secretion. Diabetes mellitus is associated with morphological and functional abnormalities. Several studies have shown that diabetes is associated with impaired pulmonary function. Pulmonary complications of diabetes mellitus (DM) have been poorly characterised. Some authors have reported normal pulmonary functions and even concluded that spirometry is not at all necessary in diabetic patients. We wanted to highlight the evidence-based significance of spirometry. METHODS This cross-sectional study was done for a period of 1 year from September 2017 to July 2018. The study sample consisted of 50 type-2 diabetes patients and 50 controls. RESULTS A total of 100 subjects were included in the present study; 50 of them were diabetics and the other 50 were non-diabetic controls matched by age, sex and body mass index (BMI). The range of forced vital capacity (FVC) in diabetic group was from 1.36 litres, which is lesser than range in controls (2.06 litres). Forced expiratory volume (FEV1) / FVC ranged from 0.59 in diabetics compared to 0.84 in controls. Mean FVC value was higher in diabetics with a duration of diabetes of less than 5 years (2.72) as compared to those with diabetes of more than 5 years (2.03) with a P value of 0.0004 which is statistically significant. CONCLUSIONS Type 2 diabetes mellitus is associated with restrictive pattern of respiratory abnormality. As the duration of diabetes increases the restrictive profile was more prominent. There was inverse relation between glycaemic status and spirometric indices FEV1 and FVC. Thus, an intensive glycaemic management may reduce the risk of death through an improved ventilator function which is independent of the other beneficial effects.

Published: May 2021

Moral values in legal science are important. However, the flow of law sees a variety of moral values. This paper aims to see the position of moral values in the science of law. Legal positivism separates strictly between law and morals. According to him, there is no law other than the command of the authorities. Even extreme identifying the law (Recht) as the law (wet). Legal positivism activities are aimed at concrete problems, which are different when compared to natural law thinking which engages itself with the validation of man-made law. For adherents of natural law theory, an unjust law is not law. there is an absolute relationship between law and morality. the two cannot be separated, so the law must refer to moral principles.
Oyster Cultivation Betting on Foreign Workers: A Study of Indonesian Workers in Hiroshima
Authors: Rustam Muhammad Reza
Published: May 2021

One of the reasons foreign workers are looking for jobs abroad is that there are not enough jobs in their home countries. Indonesia is one of the countries that send migrant workers to more developed Asian and Middle Eastern countries. The increasingly rapid flow of globalization in the world goes together with the need for new workers to fill the industry, especially in Japan. This condition has forced Japan to open doors for foreign workers from developing countries to satisfy demand. These workers usually come from developing countries, such as Indonesia, Vietnam, China, the Philippines, and others. In general, they occupy the less desirable working positions over Japanese youth, the so-called 3D work (dirty, dangerous, and demanding). Therefore, the current dynamics of these migrant workers' life in Japan becomes an exciting subject to comprehend, especially for the Indonesian migrant workers. This study aims to determine the dynamics of Indonesian worker's life while working in the Japanese fisheries sector. In particular, the study looks at those who work in oyster cultivation in Hiroshima prefecture. This research was carried out using descriptive analysis methods and field study with in-depth interviews conducted from 2016-2018. The interviews performed in this study were structured to find answers for the following questions: What problems do the workers face while living in Japan? What kind of processes did they go through before coming to Japan? While working in the Japanese fishing industry, how was their life as a Muslim minority?

Předkládaná teoretická studie se zaměřuje na otázky související s propojením formativního hodnocení a badatelsky orientované výuky ve školní praxi a k této problematice přistupuje společně pro matematiku a přírodovědné předměty (konkrétně přírodopis). Na základě společných rysů badatelsky orientované výuky v obou předmětech a s využitím teoretického modelu pro popis interakcí při poskytování okamžité zpětné vazby učitelem jsme vytvořili nový teoretický model pro popis interakcí při formativním hodnocení realizovaném během badatelsky orientované výuky. Výsledný teoretický model pro formativní hodnocení při badatelsky orientované výuce představujeme prostřednictvím sady schémat, která obecně popisují průběh výukového bloku s badatelskou úlohou z pohledu formativního hodnocení, a prostřednictvím nového tzv. double:ESRU modelu pro kódování různých typů interakcí, ke kterým dochází při formativním hodnocení. Možnosti teoretického modelu ilustrují podrobné analýzy dvou virtuálních výukových bloků s badatelskou úlohou (matematického a přírodopisného). Prezentovaný model nabízí pedagogickému výzkumu nástroj pro podrobnou přiléhavou analýzu formativního hodnocení při badatelsky orientované výuce, učitelům a budoucím učitelům nabízí nástroj pro podporu implementace formativního hodnocení a badatelského přístupu do jejich vlastní výuky. Vizualizace propojení obou přístupů a nezávislost modelu na školním předmětu by měly pomoci porozumět možnostem, které formativní hodnocení při badatelsky orientované výuce nabízí.
A Neuro-Fuzzy Model for Conflict Prediction in the Niger Delta Region of Nigeria
Authors: Ekong Victor
Published: May 2021

This paper proposes a soft computing system driven by Neural Networks, Fuzzy Logic and Principal Component Analysis (PCA) for the prediction of conflict in the Niger Delta (ND) region of Nigeria. Identifying conflicts along the level of severity with which they arise in oil bearing host communities (OBHC) is of primary importance to government and other stakeholders, as the accompanying conflict risks mitigation course administered could be planned based on the level of severity of the conflict situations. The system is implemented using MATLAB and Microsoft Excel running on Microsoft Windows 10 operating system. The data set chosen for classification and experimental simulation is based on a statistical data obtained from a three-year field study of the nine states of the ND region of Nigeria. The average training and testing errors of 0.015514 and 0.053247 were obtained at 50 epochs for the model using a hybrid algorithm. PCA reduced the dimension of the original data set at a Cronbach’s alpha of over 0.8 with a 10-fold cross validation, thereby reducing the computational complexity and inference time of the model. The model predicted the conflict risk with an average accuracy of 92.85% and this compared favourably with domain experts conventional conflict prediction approaches. The result obtained gives a promising conclusion that the model is effective in predicting at high level of accuracy, the degree of conflict and presents a veritable decision support for conflict resolution and mediation agencies and stakeholders.

Collection of Taxes from Ultimate Beneficiaries: Russian Regulatory Model
Authors: Tsindeliani Imeda , Egorova Maria , Vasilyeva Evgeniya , Bit-Shabo Inessa , Kikavets Vitaly
Published: May 2021

The problem of aggressive tax optimization and the related issue of liability of individuals who are the ultimate beneficiaries of company’s tax liabilities are becoming more and more regulatory complex. The purpose of the study, implemented using the system-functional method, is to theoretically substantiate the ways to overcome the problems that arise when collecting taxes in favor of the state from the ultimate beneficiaries. The results of the study indicate that the corporate structure cannot fully protect the beneficiary of an enterprise from property liability for committing a tax offense. The study proposes a strategy to improve the efficiency of collection of receivables from real beneficiaries. The results of this study are of great practical importance for the subjects of legislative initiative and practitioners in the field of tax legal relations. If under the conditions of the Russian legal system until 2016 it was practically impossible to prove the informal connection of a company with an actual beneficiary, then as a result of the adoption of Federal Law No. 401-FZ of November 30, 2016, the courts began to take into account any evidence that could become an argument for bringing the ultimate beneficiary to justice. This in turn led to the emergence of controversial issues. For this reason, the authors highlighted the problems arising as a result of law enforcement.

On the transmission of data packets through fiber-optic cables of uniform index
Authors: Bose Sujit K.
Published: May 2021

The treatment of Maxwell equations show that propagating wave of packets in fiber-optic cables is dispersive, propagating in groups, such that group velocity along certain curves in the frequency-phase velocity diagrams vanishes. It is suggested that stalling of wave groups is responsible, for bursting propagation observed in experimental measurements, causing some delay in transmission. The dispersion equations developed here, are different from those given in texts that are based on “weakly guiding approximation”. The queue of such data packets arriving at a router station is found to have a “raised tail” distribution unlike that of Poisson arrivals. For accounting the property, a Mittag–Leffler function distribution (MLFD) of probability is used following a modification of that for a Poisson process, the tail raising is shown to cause delay in transmission, and its estimate is analysed based on the theory.

Published: May 2021

Aiming to further plastics recycling via rotational moulding plastics processing, blends of virgin and recycled polyethylene sourced from post-consumer plastics were developed. Three different kinds of recycled high density polyethylene – from bottles, pipes and mixed household waste – were compounded with virgin medium density polyethylene in an extruder. The ideal amount of recyclate was chosen based upon the impact resistance of different contents (25, 50 and 75%) of recycled plastic with the 50/50 blend found to have the best performance. Compression-moulded and rotationally-moulded samples were analysed through falling dart impact test, flexural test, melt flow rate and differential scanning calorimetry analysis. The impact results of the compression-moulded samples showed an increase in the impact resistance of the blends with a higher melt flow index and lower degree of crystallinity. The rotationally-moulded specimens displayed much lower impact resistance than the pure virgin plastic and a 20–30% reduction in the flexural moduli, which were ascribed to the crystalline structure of the part and issues in the blends’ rotomoulding process. It was concluded that blending virgin and recycled polyethylene for rotational moulding can be an effective way to further plastics recycling inside the Circular Economy context.
The Time Varying Networks of the Interoceptive Attention and Rest

Published: May 2021

Focused attention to spontaneous sensations is a dynamic process that demands interoceptive abilities. Failure to control it has been linked to neuropsychiatric disorders like illness-anxiety disorder. Regulatory strategies, such as focused attention meditation (FAM), may enhance the ability to control focused attention particularly to body sensations, which can be reflected on functional neuroanatomy. The functional connectivity (FC) related to focused attention has been described, however, the dynamic brain organization associated to this process and the differences to the resting state remains to be studied. To quantify the cerebral dynamic counterpart of focused attention to interoception, we examined fifteen experienced meditators while performing a 20-min attentional task to spontaneous sensations. Subjects underwent three scanning sessions obtaining a resting-state scan before and after the task. Sliding window dynamic FC (DFC) and k-means clustering identified five recurrent FC patterns along the dorsal attention network (DAN), default mode network (DMN), and frontoparietal network (FPN). Subjects remained longer in a low connectivity brain pattern during the resting conditions. By contrast, subjects spent a higher proportion of time in complex patterns during the task than rest. Moreover, a carry-over effect in FC was observed following the interoceptive task performance, suggestive of an active role in the learning process linked to cognitive training. Our results suggest that focused attention to interoceptive processes, demands a dynamic brain organization with specific features that distinguishes it from the resting condition. This approach may provide new insights characterizing the neural basis of the focused attention, an essential component for human adaptability.
Transcribing Greece, Arranging France: Bourgault-Ducoudray’s Performances of Authenticity and Innovation
Authors: Asimov Peter
Published: May 2021

Louis-Albert Bourgault-Ducoudray (1840–1910), composer, folklorist, and long-time professor of music history at the Paris Conservatoire, dedicated intense energies to the propagation of ancient Greek modes as a modern resource for French composition. Instigated by his 1875 folk-song collection mission in Greece and Anatolia, Bourgault-Ducoudray’s attraction to Greek modes was bolstered by ideological commitments to Aryanism (nourished by his relationship and correspondence with philologist Émile Burnouf), and further reinforced by his observation of “Greek modes” in Russian and Breton folk song.

This article examines how Bourgault-Ducoudray translated his quasi-philological analyses into an artistic agenda through techniques of transcription, arrangement, and composition. Beginning with a close reading of his important collection, Trente mélodies populaires de Grèce et d’Orient (1876), a continuity is established between his transcriptive and compositional practices, with particular attention paid to Bourgault-Ducoudray’s performances of authenticity through calibrated scientific and artistic rhetoric. I then turn to the reception of Bourgault-Ducoudray’s collection by two composers—Alfred Bruneau and Camille Saint-Saëns—who rearranged his Greek songs in different contexts. Treating the songs with remarkable plasticity, they appropriated Bourgault-Ducoudray’s authority to enhance representations of “oriental” and “ancient” worlds, negotiating a balance between scholarly research and artistic integrity. The article concludes by returning to Bourgault-Ducoudray’s work in the 1880s—a period during which the musical and ideological ambitions of his song arrangements were magnified to an operatic scale—culminating in a rereading of his Thamara (1891) in light of his ethnic nationalism.
Effect of titanium dioxide on some mechanical, thermal, and surface properties of wood-plastic nanocomposites
Authors: Kaymakci Alperen
Published: May 2021

The effects of TiO2 (titanium dioxide) loading were evaluated relative to mechanical, thermal, and surface properties of the wood-plastic nanocomposites (WPNs). Pine wood flour, mixed with maleic anhydride polypropylene (MAPP), TiO2 nanoparticles (0 wt%, 1 wt%, 2 wt%, 3 wt%, 4 wt%, and 5 wt%), and polypropylene, was compounded in a twin screw co-rotating extruder. The mass ratio of the wood flour to polypropylene (PP) was 50/50 (w/w) in all compounds. Test specimens were produced using injection molding machine from the pellets. Flexural and tensile properties, thermogravimetric analysis, surface roughness, wettability, and morphology of the manufactured nanocomposites were evaluated. Flexural and tensile properties of the wood-plastic nanocomposites increased with the increasing content of the TiO2. The surface roughness of the wood-plastic nanocomposites was reduced by increasing the content of TiO2. Increasing the loading of TiO2 increased the amount of residual ash and thermal stability.

Published: May 2021

Eichhornia crassipes (water hyacinth) was pulped by means of a kraft pulping process with reagent loads of 10 and 20% on a dry matter basis to determine yield, rejects, kappa number, and ash. Fiber classification, brightness, opacity, and viscosity were measured in the brown pulp. Bleaching was performed by means of an O1O2D1(PO)D2HD3 sequence. Yield, kappa number, pH, ash, brightness, opacity, and viscosity were evaluated in the bleached pulp. Finally, a microanalysis of inorganic elements was carried out in both the bleached and unbleached pulp ash. The highest kraft pulp yield was 26.4%, with a 10% reagent load at 120 °C and 30 minutes cooking. It was determined that E. crassipes cellulosic pulp contains large amounts of fines. Results of the bleaching sequence indicate low brightness (58.0 %) and low viscosity (6.43 cP). The most abundant inorganic elements in the ash of both bleached and unbleached pulp were Ca, Mg, P, and Si. These results suggest that E. crassipes biomass might complement cellulosic fibers in pulping processes of low yield, such as the wood fibers used to produce handmade paper.

AbstractThis research aims to find out how students in Fiqh learning should have the ability to direct or form themselves in the learning process, what will be studied and to what extent, when, and how they will learn. Thus, students do not just become passive recipients in the learning process itself. In this case, it also emphasizes the importance of emotions, open communication and the values that each student has. This type of research uses a qualitative research methodology with a focus on literature research methods (data collection/sources). The results of this research show that Fiqh subjects in madrasas and public schools that should be able to raise awareness of students in terms of religion after studying Fiqh are increasingly motivated to practice it, but in fact, the students have not been able to adjust the learning maximally in their daily lives.                                                                      Abstrak     enelitian ini bertujuan untuk mengetahui bagaimana siswa dalam pembelajaran Fiqih harus memiliki kemampuan mengarahkan atau membentuk diri sendiri dalam proses pembelajaran, apa yang akan dipelajari dan sejauh mana, kapan, dan bagaimana mereka akan belajar. Dengan demikian, siswa tidak hanya menjadi penerima yang pasif dalam proses pembelajaran itu sendiri. Dalam hal ini juga ditekankan pada pentingnya emosi, komunikasi yang terbuka dan nilai-nilai yang dimiliki setiap siswa. Jenis penelitian ini menggunakan metodologi penelitian kualitatif dengan menitikberatkan pada metode penelitian kepustakaan (pengumpulan / sumber data).

Improving modern dairy farming is based on the industry's development, which means transforming livestock farming into a competitive industry. The development of its technical and technological support is closely related to its functional ability to realize the genetic potential of biological objects of production with high-quality products, which is the defining criterion for the competitiveness of machinery and technology at the industry’s present stage of development. The purpose of the research was to study milk production technology based on a comprehensive assessment and implementation of modern milking equipment, maximizing animals’ genetic potential and industry efficiency. We proved that applying the ‘DeLaval’ milking parlor under the same feeding and keeping animals ensured the proper completeness of milking and increased cows’ milk yield. During the first, third, and highest lactations, the milk yield was 226 kg (P=0.05), 266 kg (P=0.05), and 214 kg (P=0.05), respectively. After-milking when applying ADM-8A averaged 175 ml, and only 45 ml when applying the ‘DeLaval’ parlor. When using the ‘DeLaval’ milking equipment, the milk production intensity of cows was 1.43 kg/min, and, with ADM-8A, it was 1.24 kg/min, which is 0.19 kg/min (P=0.001), or 15.3% higher.

We presented the analysis of water consumption, growth, and development of maize hybrids depending on crops and fertilizer density. We conducted our research under Bila Tserkva National Agrarian University (Ukraine) educational and production center conditions in 2017-2019. During the active growing season of corn plants (June), moisture reserves in the 0-20 cm layer of the soil decrease to the level of unsatisfactory, and the plants experience a lack of moisture. Although, as results of defining moisture stocks in 0-100 cm layer of soil show, plants begin to assimilate it in the third ten-day period of May actively, and there is a sharp transition to good moisture stocks in the first ten-day period of June and to poor ones in the second and third ten-day periods of June. Cultivation of maize hybrids with FAO over 400 in unstable moisture conditions is quite risky because plants experience a significant lack of moisture in periods of their active growth and development. We have proved that at the density of crops within 55000/ha, the highest coefficients of water consumption were observed compared to plant densities of 65000 and 75000/ha. At hybrid DO Pivikha, the difference between average values of coefficient of water consumption at densities of crops 65000 and 75000/ha, was 25.5 and 46.75 m3/t, at hybrid DO ORLIK – 14.25 and 41.0 m3/t and at hybrid DO SARMAT respectively 17.5 and 39.0 m3/t. We found that the mineral system of fertilization compared with the organic-mineral and organic promotes water consumption growth per unit production in DN Pivikha by 4-15 m3/t, in DN ORLIK by 1-7 m3/t, and in DN SARMAT by 7-15 m3/t. The obtained patterns, for the most part, do not exceed the value of NIR0.05. In general, the duration of the growing season of the plants of the hybrid DO Pivikha was 109 days, and the hybrid DO ORLIK was 122, and the hybrid DO SARMAT was 129 days. These hybrids were in optimal conditions for growth and development and met the declared values of FAO, since for PO Pivikha, the limits of the optimal duration of the vegetation period were determined as 107-115 days, for the hybrid DO ORLIK - 120-125, and for the hybrid DO SARMAT - 128-130 days.

The microbiota of winter wheat seeds from the North-East of Ukraine was studied by a biological method. Its considerable variability is established over three years (2017–2019). The effect of the treatment agents on most microorganisms of wheat seed microbiota in Ukraine, rather than on its genera and species, is shown. It has been proven that fungicides deleted some species and did not affect the development of others. Chemicals replaced some species or genera of fungi with others or even other microorganisms. Biological seed treatment (Phytosporin-M) has caused less microbiota change than chemical treatment (Maxim 0.25 FS, Rostock, Kinto Duo). Fungicides have replaced the dominance of Alternaria spp. (2017 – 57.8%, 2018 – 63.5%) for the dominance of yeast (Rostock – 54%) and Aureobasidium pullulans (Maxim 0.25 FS – 84.2%) in 2017, bacteria (Maxim 0.25 FS – 72.3%, Rostock – 53.8%) – in 2018. A. pullulans dominated in the microbiota of winter wheat seeds in 2019. The highest amount of A. pullulans was noted for the treatment of seeds by Phytosporin-M (85.9%). The biological seed treatment reduced the amount of Nigrospora spp. and Alternaria spp. Several times (3 and 5, respectively), chemical agents did not give Nigrospora spp. germination reduced the amount of A. pullulans, Alternaria spp. in 2019. Maxim 0.25 FS, Rostock 50%, and Kinto Duo delayed seed germination and seedling development on agar medium and soil, whereas Phytosporin-M – on the contrary, promoted the growth of seedlings and significantly exceeded control.
Anguish in the dream
Authors: Müller Marcos José
Published: May 2021

In this article, my objective is to confront a structural reading (of Freud’s and Lacan’s meaning) with an ontological reading (of Merleau-Ponty’s meaning) concerning the genesis and clinical interpretation of dreams, regarding the formal operators who guide both readings, highlighting their differences. Beyond the “symbolic operator” - tasked with explaining the formation of unconscious desires that the dream would fulfill - it is my purpose to discuss the difference how - in each reading - the “real operator” is employed. In both, the real is pointed out as what would explain the emergence of anguish before which the dream would find a limit, leading the dreamer to awake. Therefore, according to each of the readings, the real concerns very different occurrences. And the question I intend to answer in this article is: how does each of these ways of understanding the real affect the comprehension of what anguish is in the dream field? In what sense, for Merleau-Ponty, can the dream be understood as a surreal passage?

Human perceptions vary between rural and urban environments, determining the degree to which people are able to coexist with biodiversity. It is important to identify the sociodemographic factors that determine these local perceptions to adjust amphibian conservation strategies in recognition of the particular conditions of different human communities. In this research, the effect of the urban or rural location where people live and sociodemographic variables in the knowledge and perceptions about amphibians was determined. The data were collected through individual semi-structured surveys of 401 participants. We measured seven response variables through the Likert scale, which ranges from 1 (totally disagree) to 5 (totally agree). For each response variable, a multivariate analysis of variance was performed. Ninety-two percent of people correctly recognized frogs and toads as amphibians, but there was confusion in classifying caecilians and salamanders within this group or including reptiles within amphibians. This confusion was more evident for women from urban locality. Positive perceptions of amphibians varied between urban and rural locality for young adults, people with a high school education level, and people without formal education. Negative beliefs varied between urban and rural locations for women, adolescents, young adults, and professionals. Half of the people accepted information on the conservation of amphibians. Positive perceptions of people about amphibians should be used as a flag to strengthen environmental educational strategies, mainly in urban locations. The results suggest that amphibian conservation plans that aim to inform and educate the public should be focused differently for age groups, genders, and educational level for people in urban and rural locations.

Introducción. El uso de biotecnologías reproductivas ha significado una mejora relevante sobre los parámetros de eficiencia y rentabilidad en la industria porcina. Objetivo. Determinar el estado del arte en el que se encuentra la biotecnología aplicada al estudio del semen y la implementación; en granjas porcinas; de técnicas de reproducción asistida como la inseminación artificial. Desarrollo. En el sector porcino, la fertilidad de los verracos (Sus scrofa domestica) tiene un efecto significativo sobre la eficiencia general de la reproducción de las piaras. Aunque hay métodos objetivos de valoración precisa de las variables seminales de los verracos, muchas granjas aún continúan realizando sus evaluaciones de forma subjetiva. Los conceptos bioquímicos que determinan la funcionalidad del gameto masculino o espermatozoide son molecularmente complejos, sin embargo, pueden conocerse los aspectos generales de la funcionalidad y desarrollar métodos de manejo del semen que permita el mantenimiento de las condiciones óptimas de las muestras seminales o dosis de semen utilizadas en inseminación artificial (IA). Dentro de la funcionalidad espermática intervienen parámetros clásicos de volumen, concentración y movilidad que son fundamentales para la optimización de las dosis seminales producidas por verraco. Los sistemas CASA (Computerassisted semen analysis) son una aplicación biotecnológica que desplaza el análisis subjetivo tradicional del semen para la valoración de la calidad, estos aportan grandes volúmenes de información que han permitido explorar más en detalle los eyaculados porcinos. Conclusiones. En las granjas que utilizan la inseminación artificial, el uso de técnicas biotecnológicas para el análisis seminal, constituye un valor agregado para el estudio de la calidad del semen y la optimización de dosis seminales producidas.
