Bioconcentración de metales pesados (Zn, Hg, Pb) en tejidos de Ariopsis felis y Diplodus annularis en el río Ranchería, Norte de Colombia
Authors: Argumedo C. D.
Published: November 2021

La contaminación por metales pesados en los ecosistemas acuáticos en el planeta es una de las más severas problemáticas que comprometen la seguridad alimentaria a nivel local, regional y global. En este estudio, se aborda el problema específico de la bioconcentración de mercurio (Hg), plomo (Pb) y Zinc (Zn) en los tejidos orgánicos de 2 de las especies de peces (Ariopsis felis y Diplodus annularis) de mayor importancia alimenticia para los pobladores rivereños del río Ranchería, al norte de Colombia. Las muestras de tejido orgánico se sometieron a una digestión ácida (HNO3 y HClO4 en relación 3:1) y la cuantificación de los metales se realizó por espectrofotometría de absorción atómica. Adicionalmente, se midieron los niveles de los metales en el sedimento, con el objeto de determinar índices de calidad medioambientales, lo que permitió determinar que los metales pesados no presentan riesgo para los organismos acuáticos que habitan en esta zona. Se encontraron diferentes valores de concentración de metales pesados: en orden decreciente, Zn > Hg > Pb, en sedimento, y Hg > Zn > Pb, en el tejido biológico. Los resultados muestran que las concentraciones de los metales pesados presentes en el tejido de los peces y en el sedimento guardan una correlación positiva y una regresión lineal estadísticamente significativa (p = 0,001, p < 0,05). La presencia de metales pesados en el sedimento del río y de bioconcentrados en los peces podría derivarse de fuentes puntuales y difusas relacionadas con actividades agrícolas, pecuarias, mineras y aguas residuales.

Authors: Ramrakhiani Sonia H. , Byrne Andrew M. , Sink Christopher A.
Published: November 2021

Although international students comprise a significant percentage of the college population, limited attention is directed to their safety needs. This study measured the experiences and perceptions of campus safety among international college students in the United States. The researchers sampled participants from institutions around the country, who self-identified as international students. A researcher-developed 53-item Likert scale questionnaire, the International College Students’ Safety Questionnaire (ICSSQ), was administered to the sample. Findings from the exploratory factor analysis provided preliminary evidence for a four-factor solution for the 26-item ICSSQ with adequate internal consistency. Salient demographic variables, such as, nationality, college status and perceived proficiency in English, were found to be significantly linked to derived factor scores. Implications for institutional adoption of this instrument, along with limitations and directions for future research are included.
Your True Colors
Authors: Guerin Ana
Published: November 2021

This poem reflects the author’s heartbreak, disappointment, and the realization that people may not show who they truly are to one. The author describes feeling disappointment and a sense of guilt from a previous relationship. The person she thought she knew turned out to be someone who did not align with her values. The author is a Mexican American woman who immigrated to the United States as a teenager from Mexico. She found within herself to educate herself through her adult life seeking to erase internalized patriarchy and oppression. Living through such divisive political environment between 2017 and 2020, she began to realize people around her, in specific the relationship illustrated in the poem, were not who she thought they were. The author describes the end of the relationship with a play on words declaring that she does not want to see this person’s dull colors again.

Arceuthobium tsugense (Viscaceae): four subspecies with contrasting morphologies and host distributions
Authors: Mathiasen Robert L. , Kenaley Shawn C.
Published: November 2021

There have been four subspecies of hemlock dwarf mistletoe (Arceuthobium tsugense: Viscaceae) described by various investigators of this complex group of parasitic flowering plants: subsp. tsugense, subsp. amabilae, subsp. contortae, and subsp. mertensianae. As suggested by their subspecific epithets, these taxa differ in their host affinities; parasitizing different and the same hosts to varying degrees. Although these taxa also have morphological differences, their classifica-tion has been under debate for many years. Therefore, we compared the morphological characteristics of each subspecies using both univariate and multivariate statistical analyses in order to better assess their differences. Because some investigators have grouped hemlock dwarf mistletoe with western dwarf mistletoe (A. campylopodum), we also compared the subspecies of hemlock dwarf mistletoe with western dwarf mistletoe. Our morphometric analyses demonstrated that all of the subspecies are morphologically distinct from western dwarf mistletoe and that subsp. contortae is the most morphologically differentiated of the subspecies. Overlap in the morphological characters across two of the other three subspecies was evident; yet, subsp. amabilae and subsp. mertensianae were also consistently delimited using female and male plant morphologies. Statistical comparisons of female or male plants via standard and stepwise discriminant function analyses demonstrated that without consideration of host plant, female and male A. tsugense subsp. tsugense are morphologically similar to corresponding plants of subsp. amabilae and mertensianae but not subsp. contortae or A. campylopodum.
The correct original spelling of Bartram’s Ixia (Ixia caelestina: Iridaceae)
Authors: Franck Alan R. , Manolaraki Eleni H.
Published: November 2021

For optimal communication, each taxonomic name ideally has one proper spelling. The specific epithet of Bartram’s Ixia has usually been spelled as coelestina, which is incorrect and contrary to the International Code of Nomenclature for Algae, Fungi, and Plants. In the protologue, Bartram originally spelled it as caelestina, which is an acceptable Latin form that ought to be adopted. The ae variant has been utilized and accepted for names of several other taxa since Bartram. The proper spelling of the basionym of Bartram’s Ixia is Ixia caelestina.

These species were not previously listed in the most detailed previous floristic study in this area Floristic Studies in North Central New Mexico, U.S.A. the Tusas Mountains and the Jemez Mountains by Reif et. al. (2009). Most of these specimens are housed in the Jemez Mountain Herbarium (JMH) at the Los Alamos, New Mexico Nature Center. Others are housed in the herbarium at the Museum of Southwestern Biology at the University of New Mexico (UNM), and a few elsewhere as noted (SEINet).

                If this number is added to the total for the Jemez Mountains from Reif’s work, the new total for the Jemez Mountains is 1,504 taxa. These additions include seven new state records, as well as several species not expected in the Jemez Mountains environment and altitude range. Of special interest are the flora of the San Pedro Parks Wilderness in the northwest part of the range, White Rock Canyon along the Rio Grande, and the desert shrublands west of San Ysidro at the extreme southwest part of the Jemez Mountains. For completeness, we include species escaped from cultivation but apparently well established in the wild, and a list of species that have not recurred where they were collected.

Authors: Philip Apraku Tawiah , Kingsley Arhin-Wiredu , Kwabena Oppong , Bernard Nii Torgbor , Phenehance Effah Konadu , Albert Abaka-Yawson
Published: November 2021

Background: In recent times, the novel coronavirus disease is one of the most challenging public health burdens. Low-and-middle-income countries including Ghana have not been spared by the infection. Several measures are being undertaken by countries to control and prevent the future waves of the disease. Previous studies have established the importance of knowledge, attitude and practices towards an infection as a remedy for controlling the spread of such infection. However, further studies are required to ascertain the socio-demographic characteristics influencing the knowledge, attitude and preventive measures of COVID-19. Methods: This study investigated the socio-demographic characteristics influencing knowledge, attitude and preventive practices towards COVID-19 among the Ghanaian population. A cross-sectional design was adopted to recruit 369 participants for the study utilizing convenience and snowball sampling methods. With the use of an electronic semi-structured questionnaire and social media platforms, an online survey was conducted from March 26 to May 1, 2020. Descriptive statistics, independent t-test, chi-square test, one-way analysis of variance (ANOVA) and linear regression were used to analyze data. Results: The average mean percentage of good knowledge, positive attitudes and good preventive practices regarding the novel coronavirus disease was 83.2%, 88.2% and 69.2%, respectively. In relation to occupation, there was significant difference (t = -2.984, p-value = 0.0030) in COVID-19 knowledge. Income level was significantly associated with attitudes towards COVID-19. Male gender (vs female, β = -1.276, p-value = <0.00001), less than ¢500 income earners (vs above ¢1000, β = -0.845, p-value = 0.017) were associated with lower COVID-19 preventive practice score while being the 42-64 age category (vs 18–25-year group, β = 1.128, p-value = 0.028), health worker (vs non-health worker, β = 0.816, p-value = 0.001) and belonging to Ga ethnic group (vs Akan ethnic group, β = 0.89, p-value = 0.027) were associated with higher scores. Conclusion: Although this study found higher knowledge and attitudes toward the novel coronavirus disease, it did not reflect in higher preventive practices towards the infection. In our fight against this infection in Ghana, COVID-19 preventive measure educational campaigns targeting the male gender and low-income earners should be considered and implemented.

Antimullerian hormone
Authors: Bebia Z. N. , Orlov V. M.
Published: November 2021

Antimullerian hormone (АМН) (also called Mullerian Inhibiting Substance) is the gonadal hormone. It is a member of the transforming growth factor-bb family of peptide growth and differentiation factors. АМН is produced in both male and female gonads - by Sertoli cells of the testis and granulosa cells of the ovaries. During the male embryogenesis АМН causes regression of Mullerian ducts, and testosterone stimulate the differentiation of wolffian system. During female embryogenesis, in the absence of АМН and testosterone, mullerian structures differentiate and develop into female internal genitalia and wolffian ducts regress.

АМН continues to be produced by the granulosa cells of the ovary during the reproductive life of the women. АМН is known to inhibit resumption of meiosis in oocytes. Besides, АМН disturbs ovarian steroidogenesis: it decreases aromatase activity, leading to lowered estradiol production and hyperandrogenia in the follicle. АМН inhibits granulosa cells mitosis and decreases the number of LH-receptors on the granulosa cells. АМН is the antagonist of Epidermal Growth factor ( EGF) and might inhibit EGF-stimulated secretion of tissue-type plasminogen activator (tPA), which plays significant role in the ovulatory rupture of the follicle.

Thus, АМН exerts inhibitory influence on all follicular components, including granulosa cells growth, steroidogenesis, oocyte maturation and follicle rupture process. It suggests, that АМН might play certain role in pathogenesis of chronic anovulation (polycystic ovaries syndrome).

Published: November 2021

One of the motives behind the establishment of the Women's Medical Institute (WMI) in 1897 was the need to radically improve the delivery of obstetric and gynecological care to the population. At that time, qualified medical aid could only be provided by a male doctor, which severely limited the demand for it by women, who were more willing to use the services of midwives and obstetricians-practitioners. The training of female physicians, specialists in obstetrics and gynecology, was the dictate of the times. In the "Regulations" on the establishment of the Institute, its main objective was formulated: "to provide women with a medical education, mainly adapted to the treatment of women's and children's diseases and obstetric activities.
Drop-in and retrofit refrigerants as replacement possibilities of R134a in domestic/commercial refrigeration and automobile air conditioner applications
Authors: HMOOD Kamel S , APOSTOL Valentin , POP Horatiu , BADESCU Viorel , POP Elena
Published: November 2021

According to the EU F-gas Regulation, the phase-out of the high global warming potential (GWP) refrigerants (with higher than 150 GWP value) had been established. The most currently existing household and commercial refrigerators and automobile air conditioners applications based on single-stage vapour compression systems operate with R134a as working fluid. The present paper aims, to review and evaluate the performance of a set of eco-friendly alternatives refrigerants to replace R134a, without change or with minor modifications in refrigeration equipment. The theoretical and experimental studies performed in this field of research were reviewed for this objective. These alternative refrigerants are some of HFCs, HFOs and HCs and their mixtures, which are expected to be an excellent candidates in many refrigeration applications. There are Many replacement possibilities had been proposed viz. drop-in replacement, retrofit refrigerant, and new systems. The results exhibited that the most suitable refrigerants as R134a drop-in substitutes are R1234yf, R152a, R450A, and R513A. The pure R1234ze and its mixtures are not suitable drop-in replacements of R134a but can be a good alternative to R134a only in new refrigeration systems. In terms of hydrocarbon refrigerants R290, R600, and R600a could replace R134a with some modifications to existing refrigeration systems to overcome the flammability issue. We should be using certain HFC and HC mixtures with the lowest TEWI index.

CRIB II score ranged from 3-18 with mean was 8.021±3.883 and median was 7. 73.4% (105/143) were discharged alive. Significant positive correlations were found among birth weight, gestational age, perinatal infection (p<0.001). Adverse neonatal outcome was associated with CRIB II score ≥10. Total CRIB II score with parameters of NDI like developmental delay, cerebral palsy, visual abnormality, absent ABR showed good correlation (p<0.001). Fisher Exact test revealed significant association between total score and Cerebral palsy (p=0.0005), visual abnormality (p=0.0005), absent ABR (p=0.0002).Conclusions: Perinatal risk factors influence future NDI in very low and extremely low birth weight babies. They should be identified and treated promptly to achieve good outcome.

Published: November 2021

In females breast carcinoma is the most common cancer worldwide. Globally, 2.3 million women were diagnosed and 685 000 deaths due to breast cancer were reported in year 2020. Even in the era of immunohistochemistry (IHC) and molecular studies, the aggressive nature of the breast cancer can be determined by its histological type, grade, nodal status, and metastasis. Mucinous carcinoma (MC) is a rare variant of invasive breast cancer accounting for 1-7%. It is represented by the presence of large extracellular mucin pools. Based on the mucin content two main subtypes are identified: Pure Mucinous Carcinoma (PMC) and Mixed Mucinous Carcinoma (MMC). Pure Mucinous Carcinoma (PMC) is localized in most of the cases, whereas the mixed forms tend to metastasize to lymph nodes. Hence the mixed forms often require an axillary dissection during surgery. We are presenting a case of 70 year old female who presented with the complaints of lump in the right breast since 2 months and on ultrasound work up a score of BIRADS V was given. She underwent right modified mastectomy with right axillary dissection and was diagnosed as mixed type of mucinous adenocarcinoma breast by histopathological examination. It was confirmed by IHC which showed positivity for ER, PR & Synaptophysin and negativity for Her2neu. Prognostically MC is better compared to other variants of invasive ductal carcinoma as they respond to hormone therapy.
Reusable Component Retrieval from a Large Repository Using Word2Vec with Continuous Bag of Words

Published: November 2021

A reusable code component is the one which can be easily used with a little or no adaptation to fit in to the application being developed. The major concern in such process is the maintenance of these reusable components in one place called ‘Repository’, so that those code components can be effectively identified as well as reused. Word embedding allows us to numerically represent our textual information. They have become so pervasive that almost all Natural Language Processing projects make use of them. In this work, we considered to use Word2Vec concept to find vector representation of features of a reusable component. The features of a reusable component in the form of sequence of words are input to Word2Vec network. Our method using Word2Vec with Continuous Bag of Words out performs existing method in the market. The proposed methodology has shown an accuracy of 94.8% in identifying the existing reusable component.

Authors: Dasari Kishore Babu , Devarakonda Nagaraju
Published: November 2021

Cyber attacks are one of the world's most serious challenges nowadays. A Distributed Denial of Service (DDoS) attack is one of the most common cyberattacks that has affected availability, which is one of the most important principles of information security. It leads to so many negative consequences in terms of business, production, reputation, data theft, etc. It shows the importance of effective DDoS detection mechanisms to reduce losses. In order to detect DDoS attacks, statistical and data mining methods have not been given good accuracy values. Researchers get good accuracy values while detecting DDoS attacks by using classification algorithms. But researchers, use individual classification algorithms on generalized DDoS attacks. This study used six machine learning classification algorithms to detect eleven different DDoS attacks on different DDoS attack datasets. We used the CICDDoS2019 dataset which is collected from the Canadian Institute of Cyber security in this study. It contains eleven different DDoS attack datasets in CSV file format. On each DDoS attack, we evaluated the effectiveness of the classification methods Logistic regression, Decision tree, Random Forest, Ada boost, KNN, and Naive Bayes, and determined the best classification algorithms for detection.

Published: November 2021

Purpose. To evaluate the effectiveness of bacteriocin of Enterococcus italicusONU 547 and essential oils individually and in combination against indicatorstrains of opportunistic pathogens. Methods. The antagonistic activity of essential oils and bacteriocin was determined by the optical density of the bacterial suspension of test strains (Salmonella enterica NCTC 6017, Escherichia coli АТСС 25922, Pseudomonas aeruginosa АТСС 27853, Pseudomonas putida KT 2440, Enterococcus faecalis АТСС 29212, Klebsiella pneumoniae АТСС 10031,Staphylococcus aureus АТСС 25923). The index of fractional inhibitory activity(FIC) was calculated by adding the FIC values of bacteriocin E. italicus ONU 547and the studied essential oils. The results. The maximum antimicrobial effect was caused by the essential oils of Anisum officinalis and Melissa officinalis, which suppressed the growth of test strains more than 50.0%. When using bacteriocin of E. italicus ONU 547 suppression of viability of indicator strains did not exceed 30.0%. Experimental combinations of essential oils and bacteriocin caused 4 types of consequences: synergy effect; additive effect; antagonistic effect; interactiveeffect (no interaction effect). In most cases, the combined action of bacteriocinand essential oils caused an additive effect. Conclusions. This study demonstrated the potential of using different combinations of natural antimicrobial compounds. The obtained results provide grounds for further development and optimization ofcombinations of essential oils and probiotic strains of microorganisms for use in food and pharmaceutical biotechnology.
Las cooperativas prestadoras de servicios públicos en Argentina. Noción. Tensión de los principios cooperativos. Desarrollo. Contribución social. Principales desafíos que enfrentan
Authors: Fernández Andreani Patricia A.
Published: November 2021

El modelo cooperativo de servicio público ha conseguido un gran desarrollo en Argentina en el siglo XX. Lo distintivo de estas organizaciones es que los usuarios se organizan a través de una empresa democrática para prestarse un servicio de alcance general y de interés colectivo. La contribución social de estas organizaciones excede la mera satisfacción del interés del asociado y se expande permitiendo una mejor calidad de vida del conjunto de los ciudadanos. En tiempos de crisis estas organizaciones han actuado como verdaderos colchones sociales. El mantenimiento y la supervivencia de estas entidades dependerá de las adaptaciones que exigen los tiempos actuales. El presente trabajo procura identificar los nuevos desafíos y proporcionar algunas soluciones normativas, regulatorias y de buen gobierno.

Northern Ireland’s Interregnum. Anna Burns’s Depiction of a (Post)-Troubles State of (In)security
Authors: Bartnik Ryszard
Published: November 2021

This paper aims to present the main contours of Burns’s literary output which, interestingly enough, grows into a personal understanding of the collective mindset of (post)-Troubles Northern Ireland. It is legitimate, I argue, to construe her fiction (No Bones, 2001; Little Constructions, 2007; Milkman, 2018) as a body of work shedding light on certain underlying mechanisms of (post-)sectarian violence. Notwithstanding the lapse of time between 1998 and 2020, the Troubles’ toxic legacy has indeed woven an unbroken thread in the social fabric of the region. My reading of the novelist’s selected works intends to show how the local public have been fed by (or have fed themselves upon) an unjustified—maybe even false—sense of security. Burns, in that regard, has positioned herself amongst the aggregate of writers who feel anxious rather than placated, hence their persistence in returning to the roots of Northern Irish societal divisions. Burns’s writing, in the above context, though immersed in the world of the Troubles, paradoxically communicates “an idiosyncratic spatiotemporality” (Maureen Ruprecht Fadem’s phrase), namely an experience beyond the self-imposing, historical time limits. As such, it gains the ability to provide insightful commentaries on conflict-prone relations, the patterns of which can be repeatedly observed in Northern Ireland’s socio-political milieu. Overall, the main idea here is to discuss and present the narrative realm proposed by Burns as (in)determinate, liminal in terms of time and space, positioning readers between “then” and “now” of the region.
