Authors: Rocha Danielly , Silva-Neto Habdias , Oliveira Laísa , Souza Shellyda , Santana Mário , Coltro Wendell
Published: August 2021

Forensic studies are extremally important to investigate suspected adulterations of consumable products, such as Viagra®. This report describes the determination of sildenafil citrate (SC) in commercial and adulterated tablets based on square-wave voltammetry (SWV) measurements using disposable stencil-printed carbon electrodes. The conductive ink used for the manufacture of integrated electrodes was produced by combining graphite powder and glass varnish. To promote a reusable strategy for limiting the geometric area of the electrodes, a 3D-printed holder was constructed. Detailed morphological and electrochemical characterization studies revealed well-defined graphite flakes incorporated on the polymeric substrate and a faster heterogeneous electron-transfer rate constant (Ks = 1.3 × 10–3 cm s–1). Based on the analytical performance, a linear behavior was observed in a SC concentration range from 1 to 20 µmol L–1 with limit of detection equal to 0.2 µmol L–1. The selectivity of the proposed method was evaluated and the presence of potentially interfering compounds like phosphate, lactose, paracetamol and tadalafil and no difference higher than 15% was observed. The analysis of SC was performed in commercial and seized tablets and the achieved values were 50 ± 1 mg for Viagra® tablet, 54 ± 1 mg for generic formulations 38 ± 1 mg for seized tablet. In addition, the proposed method offered satisfactory accuracy (98.2 – 102.0%) no noticeable matrix effect. Lastly, considering the achieved results, the use of stencil-printed carbon electrodes and SWV has demonstrated to be a powerful and robust analytical tool for forensic investigations.
Past, Present and Future of Multivariate Calibration in Analytical Chemistry
Authors: Goicoechea Héctor
Published: August 2021

Booksh and Kowalski, in their outstanding report, stressed that analytical chemistry has its own theory, which we all know as chemometrics. The authors indicated that chemometrics “can be used to specify exactly what information can be extracted from the data produced by any analytical instrument or method”. In accordance with this argument, it can be stated that multivariate calibration (MVC) has historically been applied to analytical chemistry, becoming one of the most important tools of chemometrics.

Published: August 2021

Coexistence between thyroid cancer and hyperthyroidism is rare, and most of the nodular lesions from which a malignant tumor is documented in this group of patients correspond to cold nodules. Justified by the increasing number of reports in the literature about malignant tumors diagnosed from hot nodules, a systematic review was carried out to determine possible factors associated with the diagnosis of thyroid cancer from hot nodules in patients with hyperthyroidism. The results suggest that the clinical diagnosis of toxic nodular goiter, nodular lesions of diameter > 10 mm and a histological type compatible with a follicular carcinoma, are factors that on their own increase the risk of making the diagnosis of cancer from a hot nodule.

Structure learning principles of stereotype change
Authors: Gershman Samuel J. , Cikara Mina
Published: August 2021

Why, when, and how do stereotypes change? This paper develops a computational account based on the principles of structure learning: stereotypes are governed by probabilistic beliefs about the assignment of individuals to groups. Two aspects of this account are particularly important. First, groups are flexibly constructed based on the distribution of traits across individuals. This allows the model to explain the phenomenon of subtyping, whereby deviant individuals are segregated from a group, thus protecting the group’s stereotype. Second, groups are hierarchically structured, such that groups can be nested. This allows the model to explain the phenomenon of subgrouping, whereby a collection of deviant individuals is organized into a refinement of the group. The structure learning account also sheds light on several factors that determine stereotype change, including perceived group variability, individual typicality, cognitive load, and sample size.
Orthographic neighbourhood effects during lateralised lexical decision are abolished with bilateral presentation
Authors: Mills Regan , Woodhead Zoe Victoria Joan , Parker Adam James
Published: August 2021

Words presented to the right visual field (RVF) are processed more rapidly than those in the left visual field (LVF), presumably because of more direct links to the language dominant left cerebral hemisphere. This effect is moderated by a word’s orthographic neighbourhood size (N), with LVF facilitation and RVF inhibition for words with large N. Across two experiments, we sought to further examine lateralised N effects. Experiment 1 examined how hemispheric dominance for language influenced lateralised N effects, in 140 left-handers using a visual half-field task with bilateral presentation. Neither typically nor atypically lateralized participants showed the expected N effect, making the results ambiguous: it could be that left-handers fail to show N effects, or the effect could be abolished by some procedural aspect. Experiment 2 looked to test these options by testing 56 right-handers who responded to the same stimulus set under the original bilateral presentation condition and under unilateral presentation. N effects were found under unilateral but not bilateral presentation. We had adopted bilateral presentation because it had been recommended as better than unilateral presentation for controlling fixation and visual stimulation; our results indicate that this is not a minor methodological modification: it can dramatically affect lateralized effects.
The (Human) Rights of Nature: A Comparative Study of Emerging Legal Rights for Rivers and Lakes in the United States of America and Mexico
Authors: Macpherson Elizabeth Jane
Published: August 2021

An international consensus of scientific experts is now demanding "immediate action" in response to the environmental, climate, and biodiversity crises. But are our legal and regulatory frameworks equipped to respond to the rapid pace of environmental degradation, biodiversity loss and climate change? What incidence is there, transnationally, of laws that seek to protect the Earth from the humans that inhabit it? In the past few decades, there is a growing social, legal, and political movement towards more ecocentric regulation of the planet, where new laws and institutions seek to protect natural resources for their own intrinsic value. In this paper, I consider recent efforts to protect the rights of rivers in the U.S. and Mexico, which are novel and emerging attempts to discover new pathways for enhanced protection of vulnerable waterways. These attempts are being pragmatically driven from the bottom up to the highest levels of the legislature or judiciary as local communities (and sometimes Indigenous Peoples) become increasingly frustrated with apathetic and complacent governmental responses to environmental challenges, using whatever legal tools and processes are available to them. However, rather than an Earth-centred revolution, efforts to protect the rights of nature are distinctly "human"; as communities appeal to human rights laws, and their enhanced constitutional status, to upset the status quo. There are important lessons to be learned from these experiences in other countries in terms of the ability to entrench transformative environmental protections via constitutional hierarchies and the potential for the rights and interests of humans to be both an enabler of, as well as a threat to, nature's rights.
Self-reported alcohol topography, past alcohol use history, and current alcohol cravings
Authors: Noel Jonathan K.
Published: August 2021

Introduction: Drinking topography is the idea that how a person drinks, in addition to how much they drink, can influence the immediate and long-term effects of alcohol consumption. Measures are often crude, and there has been little effort to associate such measures with disease status. Methods: To address these gaps, an online survey was completed by 734 U.S. participants. They described how they usually drank using a series of 20 words (e.g., chug, nip, nurse, shots). A latent class analysis was performed to identify clusters of descriptors. Past alcohol use history, as measured by the Alcohol Use Disorders Identification Test (AUDIT), and current alcohol cravings, as measured by the Desires for Alcohol Questionnaire (DAQ), were then regression on class assignment. The analysis was adjusted for age, sex, race, ethnicity, marital status, income, and education level. Results: Three LCA classes were accepted, with the class characterized by the words shot, swig, gulp, chug, and guzzle having significantly higher AUDIT (b[95% CI] = 1.22 [0.98, 1.46], p < 0.001) and DAQ (b[95% CI] = 12.9 [10.5, 15.3], p < 0.001) scores relative to the class characterized by sample, sip, and nurse. The third class predominantly used drink and sip, and was not significantly different from the sample class (p's = 0.290-0.471). Conclusions: Measuring drinking topography offers a unique way to identify individuals at risk of an alcohol use disorder or those who may be resistant to treatment. It may also be useful in determining drinking motives. However, additional research is needed.
Assessing the relationship between education and delay discounting and future planning in U.S. adults
Authors: Noel Jonathan K.
Published: August 2021

Background and Objectives: Education has been linked to mortality, but the relationship is poorly understood. The current study assessed whether delay discounting and future planning may be potential mediators in the education-mortality pathway.Methods: N = 681 U.S. adults completed an online survey. Linear and logistic regression models were specified to determine the relationships between education, delay discounting, and future planning. Models were repeated among participants with positive health attributes that may also mediate the education-mortality pathway (i.e., currently employed, had high social support, had high health literacy, and were lifetime non-smokers).Results: In the delay discounting task, participants with a high school education or less required $13.70 more than other participants (p = 0.002). The odds of having a future 10-year plan were 49% lower among participants with a high school education or less (95% CI = 0.28, 0.95). The relationships remained among those with positive health attributes.Conclusions: High delay discounting and low future planning may explain, in part, the inverse relationship between education and mortality risk reported elsewhere. Programs encouraging students to complete an undergraduate education and that directly decrease delay discounting or increase future planning are needed.

Published: August 2021

Introduction: To analyze the ART outcome and factors associated with successful ART treatment for infertilecouples in a newly set up medical university IVF centre. Methods: A six-month cohort study of patients undergoing their first assisted reproductive technique cycle was conducted at IIUM fertility centre, Kuantan (from 15th June until 31st Dec 2009). Outcome measures include clinical pregnancy rate, ongoing pregnancy rate, take home baby rate and complications rate. Results: Fifty-five first cycles of IVF/ICSI were studied. Mean embryo per transfer was 2.1±0.8. Four patients were pregnant (23.5%) from a single embryo transfer (SET). Clinical pregnancy rate was 30.9% (17/55). Ongoing pregnancy rate was 23.6% (13/55) and take home baby rate was 21.8% (12/55). There was only one twin pregnancy. Nine patients (16.4%) had OHSS whereby 77.8% were mild and 22.2% were moderate. Conclusion: Take home baby rate at the IIUM fertility centre is comparable to most established ART centres in Malaysia considering that this is only the first year of operation.

Authors: Albadri Cinaria T.
Published: August 2021

Introduction: The goal of the present study was to examine the effect of alcohol consumption on sperm count and motility and the morphological changes in the seminiferous tubules of parent mice and their offspring. Methods: Animals were divided into two groups, Group 1 (alcohol group) of twelve male and twelve female mice, were given a daily dose of (3 g/kg body weight as 25%, v/v) ethanol by gastric gavage for four and eight weeks. Group 2 (control group) also of twelve male and twelve female mice; received normal access of food and water. After four weeks of treatment, the males and females in each group were allowed to mate, and ethanol treatment continued for up to another four weeks. Twelve male offspring from group 1 and twelve male offspring from group 2 were selected randomly and allowed to become mature. Male parent mice were killed at the 4th and 8th weeks of treatment, and their male offsprings were killed when they reached maturity age. Results: Physiological examination of the sperm solution showed that there was a significant decrease in sperm count and motility after 4 and 8 weeks of ethanol treatment in parent male mice, but this decrease was not significant in their adult offspring. Furthermore, histological investigations indicated testicular lesions in the parent male mice and their adult male offspring. Conclusion: Alcohol abuse has deleterious effects on the testes structure and on the sperm count and motility of the epididymal spermatozoa of both parent mice and their offspring.
Who does SEO in Spain? A cybermetric methodology for the construction of company universes
Authors: Escandell-Poveda Raquel , Iglesias-García Mar , Papí-Gálvez Natalia
Published: August 2021

Due to their widespread use, search engines, and specifically Google, are extremely important to attract qualified traffic and thereby achieve the commercial objectives of corporations. Search engine optimization (SEO) allows enhanced connection of corporate websites with their audiences through search engines, using certain keywords. This study describes a methodology to determine the most important Spanish companies offering SEO services to third parties, representing an exploratory study of applied cybermetrics for the construction of a universe of companies. One of the relevant results of this work is the design of an information retrieval strategy based on a statistical analysis of search terms and the performance of geolocated searches in all the provincial capitals and Spanish cities with more than 100,000 inhabitants. After cleaning and reviewing the unique URLs, it is concluded that there are 1,043 companies offering SEO services in Spain positioned in Google. These are basically companies with more than one person, operating from a single location, and that offer other services in their portfolio together with SEO. In addition to providing a starting point for future research on the SEO sector in Spain, this research proposes a methodology for the creation of study universes of brands or companies.
Response Evaluation with Dynamic FDG PET/CT during the Primary Systemic Therapy of Breast Cancer - A Case Report

Published: August 2021

18-fluorine-fluorodeoxyglucose (FDG) positron emission tomography (PET) and mainly combined with
computed tomography (CT), abbreviated as FDG PET/CT is a useful and accurate tool for staging and
restaging in locally advanced breast cancer. In daily practice static images are prepared during the PET/CT
examinations. However, despite the success of static PET and PET/CT imaging, the role of precise
quantification of FDG-uptake – measured by dynamic acquisition – is ambiguous in the staging and
management of different malignancies. In this case report, we described our experience with staging, interim
and restaging dynamic PET/CT examinations of a woman suffering from breast cancer. Based on the
described case we concluded that dynamic PET/CT is suitable for accurate quantification of FDG-uptake in
primary breast tumors. However, performing dynamic PET/CT examinations is time-consuming, therefore,
it is important to define the group of patients where their use is with the most favourable benefit/risk ratio.
Furthermore, using of interim PET/CT scan is recommended in cases with clinically controversial baseline
tests. Based on literature in vivo biomarkers of the dynamic PET/CT are predictive of more favourable tumor
response and longer disease-free survival, as confirmed by our own results.

(COVID-19). Although there is emerging literature on the use of and mortality associated with V-V ECMO
in the management of patients with COVID-19, our understanding of who may benefit from this
management strategy remains limited. Our clinicians sought to provide further insight into pre-cannulation
characteristics and mortality in a cohort of patients with COVID-19 associated ARDS managed with V-V
ECMO that primarily consisted of obese patients (90%, n=18) with a BMI of 30 kg/m2 or greater. Our
findings not only revealed high survival to hospital discharge (70%, n=14) but demonstrated non-inferior
outcomes and survival in obese patients. With an imminent next wave of rising infections, knowledge of
which patients have a better chance of survival with the initiation of V-V ECMO is essential. Obese patients
have been historically underrepresented in ECMO outcomes literature, but our findings suggest the
utilization of ECMO for COVID-19 associated ARDS in these patient subsets should be considered and
outcomes should be further explored.

Safety risk assessment in dams is a traditional and modern approach to the engineering process of dams on safety systems so as to produce a design history that has a good overall record and integrity. With this approach for both old and new dams, this safety risk assessment aims to determine whether the risk the hazard can be tolerated or not, if it cannot be tolerated then there must be a solution for action to reduce the risk of danger so that the safety of the dam can be obtained. The existing risk assessment can be used as the basis for the construction of the dam to its maintenance, in this study discussed risk assessment safety on dams located in several countries such as in Asia, Europe and America. The methods implemented include the preparation of safety risks, risk analysis, risk evaluation and safety risk management. Based on research results The main risk factor that causes safety responsibilities is the Contractor's responsibility, namely the Non-technical project factor (40.54%), the 2nd rank is the Undecided Responsibility due to internal technical factors (35.13%), the 3rd rank is the technical project factor namely Contractor's Responsibility (10.8%), Rank 4 is external technical factor and external non-technical factor, the last risk factor is internal non-technical factor (2.7%) namely Joint Responsibility.

Padi beras merah yang dibudidayakan di masyarakat Sumatera Barat saat ini merupakan padi lokal. Padi lokal memiliki keunggulan tertentu karena telah dibudidayakan secara turun-temurun  sehingga telah beradaptasi dengan baik pada berbagai kondisi lahan dan iklim yang spesifik. Sebaliknya, padi lokal juga memiliki beberapa keterbatasan, antara lain berumur panjang, berpostur tinggi, tidak tahan hama dan penyakit, serta berproduksi rendah. Mutasi yaitu perubahan struktur genetik suatu makhluk hidup secara tiba- tiba dan acak yang diwariskan pada generasi berikutnya. Pemuliaan mutasi mempunyai karakter spesifik antara lain sangat efektif untuk merubah sedikit sifat dalam perbaikan varietas tanaman. Penelitian ini telah dilaksanakan  pada bulan Agustus hingga Desember 2017. Pada saat persemaian ini akan dilakukan pengamatan mutasi klorofil untuk melihat adanya indikasi  keragaman genetik akibat perlakuan iradiasi sinar gamma yang dilakukan terhadap benih. Setiap benih di persemaian diamati perubahan warna daunnya dan dikelompokkan kedalam kriteria Gustafsson. frekuensi mutan tertinggi adalah mutan dengan dosis 200 Gy, sedangkan untuk frekuensi mutasi yang tertinggi adalah tanaman yang diiradiasi dengan dosis 300 Gy. Tanaman yang diiradiasi dengan dosis 200 Gy  memiliki frekuensi mutasi sebesar 0,09% dan untuk dosis 300 Gy frekuensi mutan yang terjadi adalah0,02 %.

Sorghum (Sorghum bicolor (L.) Moench) is a cereal plant that has the potential to be cultivated and developed as a source of carbohydrates. The research objective was to identify the morphology and varieties of sorghum plants from several potential areas of West Sumatra, such as Limapuluh Kota Regency, Payakumbuh City, and Sijunjung Regency be used as a source of germplasm. The research was carried out in Limapuluh Kota District, Payakumbuh City, and Sijunjung Regency for six months starting from June-November 2020. The research was carried out with stages beginning with a survey of the location of sorghum planting, identification of plant morphological characteristics, identification of varieties/cultivars/lines, and collection of germplasm sources. Observations were made on the morphological characteristics of plants in the vegetative and generative phases based on the sorghum plant description book. The results showed differences between morphological features in the field and existing descriptions in terms of plant properties, plant height, leaf color, leaf bone, panicle density, panicle shape, panicle length starting from the neck of the panicle, shape, and color of the neck of the panicle.
Aszimmetrikus kereskedelmi kapcsolatok az olasz-líbiai viszonylatban
Authors: Takács Lili
Published: August 2021

Olaszországot és Líbiát szoros kapcsolatok fűzik egymáshoz a gazdasági biztonság területén, ez azonban nincs a tudományos kutatások középpontjában. Az aszimmetrikus gazdasági kapcsolatok a nagyobb állam számára politikai befolyást is biztosíthatnak. Az olasz–líbiai kereskedelmi kapcsolatok nagy részét a líbiai kőolaj és földgáz Olaszországba való exportja teszi ki, aminek a mennyisége 2011 óta jelentősen csökkent. Az ENI a legnagyobb külföldi szereplő Líbiában, így az ottani olasz befolyás egyik letéteményese. Az energiahordozók kereskedelme terén nincs olyan erős aszimmetria a bilaterális kapcsolatokban, mint az egyéb termékek terén, hiszen Líbia egy úgynevezett rentier state, így az Olaszországba irányuló szállításra szüksége van. A kereskedelmi kapcsolatok egyéb területein erős aszimmetria van Olaszország irányába, bár az arab tavasz óta líbiai piaci részesedése csökkent.

A szimbólumok az emberi közösségek kultúrájának szerveződésében meghatározó fontosságú elemek. Minden társadalom szimbólumrendszere kulcsszerepet játszik értékei, céljai megjelenítésében, a közösségi identitás megteremtésében, valamint egyiklegfőbb eszköze a tradicionális tapasztalatok továbbadásával a kultúra átörökítésében. Dolgozatunkban azt vizsgáljuk, milyen célok mentén születnek a szimbólumok, a társadalmi, illetve a szervezeti kultúra jelentéshordozóiként hogyan válnak a csoportazonosuláskifejezőivé, valamint milyen folyamatok során lesznek a társadalomértelmezés legfontosabb eszközei.
