Preferência para oviposição de Diatraea saccharalis (Fabricius, 1794) em variedades de arroz
Authors: Martins J. F. S. , Rossetto C. J. , Roccia A. O.
Published: May 2021

Foi estudada em condições de laboratório, a preferência para oviposição de D. saccharalis nas variedades de arroz IAC-9, TKM-6, Blue belle & Chiang an Tsao Pai Ku, em experimento de livre escolha. Houve diferença significativa entre o número de posturas colocadas nas variedades, sendo a IAC-9 a mais ovipositada. Ocorreu interação significativa entre a face da folha e as variedades, quanto a oviposição. As variedades pubescentes na face superior foram menos ovipositadas nessa face, mas não diferiram das variedades glabras na face inferior onde não há pelos. A pubescência ou um fator associado a ela exerceu uma influência negativa na oviposição. As mariposas preferiram ovipositar na metade superior das plantas, e colocaram mais ovos na variedade mais alta.

Estudo da relação entre dureza da vagem e resistência a Etiella zinckenella Treitschke, 1832 , em feijão (Phaseolus vulgaris L.)
Authors: Ramalho F. S. , Machado R. C. R. , Albuquerque M. M.
Published: May 2021

Estudou-se a re1aço entre dureza de vagem (epicarpo e grão) de feijão P. vulgaris e resistência a Etiella zinckenella. Obteve-se correlação positiva entre percentagem de vagens infestadas e percentagem de grãos danificados. Não se constatou correlação entre percentagem de vagens infestadas ou percentagem de grãos danificados com a dureza da vagem (epicarpo e grãos).

A dureza da vagem de feijão, P. vulgaris, provavelmente não pode ser considerada como fator de resistência a broca da vagem, Etiella zinckenella.

Late- and postglacial shore level changes in the southwestern Baltic Sea
Authors: Bennike Ole , Jensen Jørn Bo
Published: May 2021

Sub-marine deposits in the region of the Arkona Basin, Mecklenburg Bay and Darss Sill have been studied using a multi-disciplinary approach that includes shallow seismic work, depositional sequence stratigraphy, radiocarbon dating and analyses of diatoms and macrofossils. Models for the relative shore level changes in the two basin areas are proposed.
Both in the Mecklenburg Bay basin and in the Arkona Basin maximum shore levels of c. 20 m below present sea level were reached in late Allerød, in late Younger Dryas and in late Preboreal. The drainage of the Baltic Ice Lake led to shore level drops, but in Mecklenburg Bay the drop only amounted to around 5 m, because the Darss threshold hindered further regression.
In the Arkona Basin, the drop after the final drainage of the Baltic Ice Lake was approximately 20 m, whereas the water level falls after the Allerød drainage of the Baltic Ice Lake and after the Ancylus Lake maximum, have not yet been determined. The Darss Sill area became a land area with local lakes after the Ancylus Lake drainage; there is no evidence of erosion or fluvial/deltaic sediments in Mecklenburg Bay that could be referred to the proposed so-called Dana River.
The evolution of the shore level after the Boreal lowstand is poorly confined by our data, but hydrographic conditions similar to the present were established at c. 7.6 cal. ka BP.
Dinoflagellate cysts of the shallow marine Neogene succession in the Kalmthout well, northern Belgium
Authors: Louwye S. , Laga P.
Published: May 2021

The dinoflagellate cyst associations from the Neogene succession in the Kalmthout well allow a correlation with biozonations and key dinocyst events from the North Sea area and the eastcoast of the USA. The recovered cyst assemblages suggest that an Early Miocene (late Aquitanian – early Burdigalian) age can be attributed to the Berchem Formation, while the Diest Formation is of Late Miocene (late Tortonian – Messinian) age. The age of the Kattendijk Formation remains unclear. The Lillo Formation in the Kalmthout well is of Pliocene age and possibly not younger than early Late Pliocene.

Published: May 2021

Un factor importante en los servicios, en general, son los valores asociados a la cultura. Sin embargo, no existe suficiente literatura académica en este campo. Este trabajo enfoca estas limitaciones utilizando un modelo de valores culturales- el de Schwartz- para desarrollar un enfoque útil de instrumentación de estos valores. Estos se modelan como variables externas, para subrayar aquellos que son realmente relevantes. El trabajo se basa en una encuesta a clientes de talleres post venta en China de automóviles. Así, se evalúan los factores críticos de éxito, mediante modelos de ecuaciones estructurales de mínimos cuadrados parciales (PLS).Palabras claves: Cultura, postventa, fidelización a la marca, PLS-SEM, teoría del valor de nivel IndividualInfluences of cultural values in the automotive marketing servicesAbstract: After-sales services have become very important in the automobile industry. However, this area has not been sufficiently researched, particularly with regard to China, the most important car market globally. In this respect, German manufacturers play a leading role because they dominate the premium market segment. When it comes to services, the one thing that is especially important in China is culture. At the same time, this is exactly where a scientific gap exists because the cultural aspect in automotive services has been mostly neglected in the research literature. Thus, specific knowledge with regard to Chinese service demand behaviour is lacking, which could become a crucial issue because of the enormous differences between Chinese and Western cultures. This paper addresses this limitation by providing a guideline for how the entire process chain of after-sales services could be researched in China. In addition, it also introduces Schwartz’s individual level value theory as a beneficial operationalisation approach to culture. Thereby, values are modelled as exogenous variables in order to show which ones are really causal. This significant advantage cannot be provided by national comparison studies, which are the ones that are most often conducted. A total of 301 Chinese workshop customers of Audi, BMW and Mercedes-Benz were surveyed in order to assess the critical success factors of after-sales services via partial least squares structural equation modelling.Keywords: Culture, After-sales services, Brand loyalty, PLS-SEM, Individual level value theory.

A Treatise on the Theoretical Basis of Research on the Organizational Culture of a Police Organization
Authors: Ivančík Radoslav
Published: May 2021

In recent years, we can meet more and more often in various professional publications, magazines, conferences, but also in various reports in the media the term organizational culture. The fact is that gradually more and more organizations are dealing with issues of organizational culture because they have understood that organizational culture plays an important role in the life of organizations. And not only in formulating organizational strategy, setting goals, or making decisions, but also in fulfilling their mission, creating their image and overall functioning in today's dynamic times affected by deepening globalization. That is also why the author, in his research, deals with organizational culture, specifically, in the presented article he examines police culture. The author characterizes police culture as a specific type of organizational culture that fulfils important functions and missions in terms of police functioning. By analogy with other types of organizations, the author defines police culture as a set of socially typical views, attitudes, norms, and values that determine models of police behaviour, relations to society and the police organization. He points out that despite the generally similar characteristics with other cultures of the organization, there are certain specifics that distinguish the police culture from other organizations. It gives it uniqueness. It should be a priority for every organization to have a good organizational culture aimed at maximum efficiency and success. For this reason, it is important to know its current state by research and to evaluate its positive and negative aspects. The article deals with the theoretical basis of understanding key concepts such as organization, culture, subculture, and organizational culture. At the same time, it presents the theoretical basis for the study of this phenomenon in the environment of the Police Force.
Shifting the Battle to Social Media: The Effectiveness of Boko Haram’s Online Strategy in Terms of its Recruitment
Authors: Sinkó Gábor
Published: May 2021

In 2015, after Boko Haram pledged allegiance to the Islamic State of Iraq and the Levant and became the Islamic State West Africa Province, online social media’s dominance was nearly instantaneous. This paper analyzes whether Boko Haram’s use of social media results in more effective recruitment and, if so, what trends can be observed in the former that contribute to the latter. I conclude that social media plays an instrumental role in the terrorist organization’s online recruitment since Boko Haram can disseminate instant messages to large online audiences while also exercising control over their visual content. Additionally, Boko Haram’s use of social media ties into recruitment as there is a link to radicalization, religious indoctrination, and sharing its narrative. Finally, the group uses social media to depict itself as the winning entity by representing strength, unity, and taking advantage of the country’s anti-government sentiment. While online influences are undoubtedly crucial for recruitment, it must be emphasized that they are usually coupled with offline physical connections in the Nigerian context.
The development of science is uninterrupted
Authors: Dános Valér , Szabó Csaba
Published: May 2021

Both Pfizer-BioNTech’s and Moderna’s corona virus vaccines have been developed on the basis of the mRNA-mediated therapy, discovered by Katalin Karikó, Hungarian-born professor and senior vice president of BioNTech and her co discover, Drew Weissman, professor of the University of Pennsylvania. The greatest scientific achievement of Katalin Karikó’s research work over more than two decades is the elaboration of the mRNA-mediated method for therapeutic application. For Professor Karikó the special milestone was the moment when the first vaccine for COVID-19 was created based on this technology. Her breakthrough discovery has a potent scientific importance in vaccine research, as people are all around the world are hoping for the end of pandemic and lockdown restrictions with arrival of vaccines, wishing that life could finally return to normality. However, we have to remark that several questions emerge concerning the mechanism of action of this new type of vaccines, their side or long-term effects, as well as the duration of immunity or the risk of reinfection. These questions lead to uncertainty in connection with vaccination, therefore clear answers needed. In the fight against the virus, beside healthcare workers, military and police personnel belong to the category of highest risk of infection, therefore, it is crucial to achieve as high vaccination rates in their ranks as possible. To reach this goal, it is important to have authentic information about the vaccine and the indicators of the immune response. As, the unknown always creates fear and uncertainty we intend to put an end to such fears with the help of this interview with Katalin Karikó and to support hesitant colleagues’ decision-making process to get themselves vaccinated. We asked Professor Katalin Karikó about vaccine research, the wide area of application of the mRNA-mediated therapy, about skepticism concerning vaccination and about her personal connections to police forces and to scientific research in the field of law enforcement. She was interviewed by Valér Dános and Csaba Szabó.
Chemical Analysis of Two Extremely Metal-poor Stars HE 2148-2039 and HE 2155-2043*
Authors: Purandardas Meenakshi , Goswami Aruna
Published: May 2021

We present elemental abundance results for HE 2148−2039 and HE 2155−2043 based on a detailed high-resolution spectroscopic analysis. The high-resolution Subaru/High Dispersion Spectrograph (HDS) spectra used for our analysis have a resolution of R ∼ 60,000. Although limited information based on photometry and low-resolution spectroscopy is available, we present for the first time an abundance analysis based on high-resolution spectra for both objects. Our analysis shows that the two objects are extremely metal-poor with [Fe/H] < −3. Among the neutron-capture elements, abundances of only Sr and Ba could be determined in our program stars. For both the objects [Ba/Fe] is found to be <0. While strontium is underabundant in HE 2148−2039 with [Sr/Fe] ∼ −2.02, Sr is near solar in HE 2155−2043. The locations of the program stars in the absolute carbon abundance, A(C) versus [Fe/H] diagram, show that HE 2148−2039 is a carbon-enhanced metal-poor (CEMP)-no Group II object and HE 2155−2043 is a CEMP-no Group III object. Observed [Sr/Ba] ratios are characteristics of a fast rotating massive star progenitor for HE 2155−2043 and a metal-poor asymptotic giant branch (AGB) star for HE 2148−2039. The estimated [Sc/Mn] as well as [C/Cr] ratios in HE 2155−2043 show that the surface chemical composition of this object is mono-enriched. The surface chemical composition of HE 2148−2039 is also found to be mono-enriched based on the [Mg/C] ratio. With respect to their locations in the [C/N] versus T
eff diagram, HE 2148−2039 shows signatures of mixing, and HE 2155−2043 falls in the unmixed region of the [C/N] versus T
eff plot. Kinematic analysis shows that both objects belong to the Galactic halo population.
The Be Star 66 Ophiuchi: 60 Years of Disk Evolution

We use a time-dependent hydrodynamic code and a non-LTE Monte Carlo code to model disk dissipation for the Be star 66 Ophiuchi. We compiled 63 years of observations from 1957 to 2020 to encompass the complete history of the growth and subsequent dissipation of the star’s disk. Our models are constrained by new and archival photometry, spectroscopy, and polarization observations, allowing us to model the disk dissipation event. Using Markov Chain Monte Carlo methods, we find that the properties of 66 Oph are consistent with those of a standard B2Ve star. We computed a grid of 61,568 Be star disk models to constrain the density profile of the disk before dissipation using observations of the Hα line profile and spectral energy distribution. We find at the onset of dissipation the disk has a base density of 2.5 × 10−11 g cm−3 with a radial power-law index of n = 2.6. Our models indicate that after 21 yr of disk dissipation 66 Oph’s outer disk remained present and bright in the radio. We find an isothermal disk with constant viscosity with an α = 0.4 and an outer disk radius of ∼115 stellar radii best reproduces the rate of 66 Oph’s disk dissipation. We determined the interstellar polarization in the direction of the star in the V band is p = 0.63 ± 0.02% with a polarization position angle of θ

IS
≈ 857 ± 07. Using the Stokes QU diagram, we find the intrinsic polarization position angle of 66 Oph’s disk is θ
int ≈ 98° ± 3°.
TESS Observations of TX Col: Rapidly Varying Accretion Flow
Authors: Rawat Nikita , Pandey J. C. , Joshi Arti
Published: May 2021

Using the first long-term photometry from the Transiting Exoplanet Survey Satellite, we have carried out a detailed time-resolved timing analysis of an intermediate polar TX Col. The power spectra of almost 52 days of continuous time-series data reveal the orbital period of 5.691 ± 0.006 hr, spin period of 1909.5 ± 0.2 s, and beat period of 2105.76 ± 0.25 s, which is consistent with the earlier results. We have also found the presence of quasi-periodic oscillations (QPOs) for a few days with a period of 5850–5950 s, which appears to be due to the beating of the Keplerian period with the spin period of the white dwarf. The continuous data allowed us to look thoroughly at the day-wise evolution of the system’s accretion geometry. We report here that the TX Col changes its accretion mechanism even on a timescale of one day, confirming its variable disk-overflow accretion nature. For the majority of the time, it was found to be disk-overflow system with stream-fed dominance; however, pure disk-fed and pure stream-fed accretions cannot be ruled out during the observations.
Resolving the Complex Evolution of a Supermassive Black Hole Triplet in a Cosmological Simulation
Authors: Mannerkoski Matias , Johansson Peter H. , Rantala Antti , Naab Thorsten , Liao Shihong
Published: May 2021

We present here a self-consistent cosmological zoom-in simulation of a triple supermassive black hole (SMBH) system forming in a complex multiple galaxy merger. The simulation is run with an updated version of our code KETJU, which is able to follow the motion of SMBHs down to separations of tens of Schwarzschild radii while simultaneously modeling the large-scale astrophysical processes in the surrounding galaxies, such as gas cooling, star formation, and stellar and AGN feedback. Our simulation produces initially an SMBH binary system for which the hardening process is interrupted by the late arrival of a third SMBH. The KETJU code is able to accurately model the complex behavior occurring in such a triple SMBH system, including the ejection of one SMBH to a kiloparsec-scale orbit in the galaxy due to strong three-body interactions as well as Lidov–Kozai oscillations suppressed by relativistic precession when the SMBHs are in a hierarchical configuration. One pair of SMBHs merges ∼3 Gyr after the initial galaxy merger, while the remaining binary is at a parsec-scale separation when the simulation ends at redshift z = 0. We also show that KETJU can capture the effects of the SMBH binaries and triplets on the surrounding stellar population, which can affect the binary merger timescales as the stellar density in the system evolves. Our results demonstrate the importance of dynamically resolving the complex behavior of multiple SMBHs in galactic mergers, as such systems cannot be readily modeled using simple orbit-averaged semianalytic models.
Les dispositifs Balint : « filiations apostoliques » et excitation. « Le réveil des volcans et l’antique déchirure »

Published: May 2021

Avec cet article reprenant le récit des fondations d’un dispositif groupal de formation psychanalytique : les « Journées Balint d’Annecy », les auteurs ont souhaité rendre un hommage à Simone Cohen-Léon qui s’y était beaucoup investie. Ils ont pris appui sur une situation clinique d’excitation dans un groupe pour illustrer les enjeux « pré-contre-transférentiels » dans la mise en place et dans le déroulement du dispositif. Ils formulent l’hypothèse de manifestations groupales d’excitation comme le témoignage d’effets fantômes survenus dans le groupe en héritage de la transmission non élaborée d’une généalogie du dispositif, de son histoire de ses origines et de ses filiations. Ils questionnent les aménagements du dispositif groupal Balint, avec l’introduction de la relaxation analytique groupale développée par Michel Sapir mais aussi de la mise en scène du corps par le psychodrame Balint développée par Anne Caïn. Peut-on y reconnaître l’apport dans les dispositifs de groupe Balint à médiation verbale, d’une médiation spécifique mobilisant une écoute du corps des participants ? Comment ce fond constant du pulsionnel, du « corps en relation », du corps individuel et groupal s’inscrit-il dans une pratique psychanalytique groupale ?
Emotional Intelligence and Coping Strategies as Predictive Variables of Muscle Dysmorphia Symptoms in a Population of Men
Authors: Herráez Beatriz Gómez , Giráldez Carlos Alberto Marchena
Published: May 2021

The current study analyzes the relationship among the variables of muscle dysmorphia (MD) emotional intelligence (EI), and coping strategies (CS), as well as the role of EI and CS in predicting MD symptoms in 112 men between ages 18 and 30 years. The Muscle Dysmorphia Disorder Inventory, the Trait Meta-Mood Scale 24, and the COPE-28 questionnaire were used as measures. We calculated descriptive statistics, correlation analysis, and linear regression. Results show that an inadequate EI (excessive emotional attention or a lack in both emotional clarity and repair) is related to higher levels of MD symptoms. Likewise, almost all maladaptive CS showed significant positive correlations with MD symptoms, whereas just one adaptive CS showed negative correlation with MD symptoms. Only some CS (acceptance, self-blame, and denial) were shown to be predictors of MD symptoms, and they accounted for 36% of the variance.

Situational Awareness Huddles in a Pediatric Cardiac Intensive Care Unit During the COVID-19 Pandemic
Authors: Christensen Kristen , Colman Nora , Van Voorhis Kay , Daniels Katherine , Culpepper Haley , Hebbar Kiran , Wolf Michael
Published: May 2021

Background

The COVID-19 pandemic has created challenges for provider teams working in intensive care units, including rapidly changing patient care regulations, staffing considerations, and preservation of personal protective equipment. The need for enhanced respiratory precautions for infected patients and patients under investigation has necessitated a new process for interventions and resuscitation.

Local Problem

Along with changing regulations and equipment, significant staff anxiety surrounded caring for infected patients and preparing for emergency situations.

Methods

A huddle process was implemented in the pediatric cardiac intensive care unit for acutely ill patients who required enhanced respiratory precautions and were at risk of imminent decompensation, or who required a bedside procedure. During a huddle, the multidisciplinary team used process maps displayed in patient rooms; the huddle process created a situational awareness of events among these teams.

Intervention

After implementation of huddles, a survey was distributed to cardiac intensive care unit staff in order to understand their satisfaction with the huddle process.

Results

A total of 36 staff responded to the survey. They thought the huddles helped them to prepare for resuscitation scenarios, helped limit the number of personnel responding to an emergency, and reduced their anxiety surrounding caring for these patients. Staff suggested generalizing this huddle process to all patients at acute risk for decompensation in the cardiac intensive care unit.

Conclusions

A novel huddle process created situational awareness among staff caring for patients requiring enhanced respiratory isolation because of COVID-19. Multidisciplinary huddles allowed staff from various disciplines to apply a process map for interventions and resuscitations among critically ill children with heart disease.
Protecting Our Service Members: Sexual Assault Response Reform in the US Military
Authors: White Ben
Published: May 2021

Rampant sexual assault is a dark stain on the prestige of the United States military. Reported cases of sexual assault have risen year-after-year over the past decade, and the statistics make it abundantly clear that the systems currently in place to protect those who have sworn to defend us have failed. In the months since the horrific and highly publicized death of Army Specialist Vanessa Guillen, the American public has seen an increasing number of calls for sweeping change to the ways that sexual harassment and sexual assault are handled in the military, but there are a number of barriers that stand in the way of sustainable reform. Foremost among these challenges is the chain of command involvement in the reporting and prosecution process, which is often avoided by victims out of a legitimate fear of workplace retaliation.
An Economic Analysis of the Reservation Policy in India
Authors: Basu Sampurna
Published: May 2021

Persistent socio-religious stratification in India has resulted in widespread inequity in all spheres of life, particularly for those born in the lower ranks of the social caste order. The effects of these inequities are visible amongst the lower caste in the form of poverty, low standards of living, unemployment, and lack of education. To counter this, India’s government introduced a reservation policy as a form of affirmative action that reserves a percentage of legislative seats for the Scheduled Castes, Scheduled Tribes, and Other Backward Castes in the spheres of education, employment, and politics. This paper looks into the usefulness of this policy in making better opportunities available for the Scheduled Castes and Scheduled Tribes and examines its effectiveness using economic analysis. In doing so, the paper explores certain problems, such as ambiguous data, child labor, and rent-seeking behavior, and recommends setting up better screening methods to rectify these issues in an effort to ensure equitable distribution of welfare benefits amongst the recipients of the reservation policy.
Drawbacks and Aftermath of the Affordable Care Act: Ex-Ante Moral Hazard and Inequalities in Health Care Access
Authors: Corso Daniele
Published: May 2021

Background

Following the introduction of the Affordable Care Act, various studies have tried to identify the effects of the reform, without reaching a clear consensus. The aim of this study was to investigate whether expansion of the Medicaid program has led to less inequality in access to health care and to a higher level of ex-ante moral hazard.

Design and methods

The analysis was conducted on two-year longitudinal data (2014-2015) regarding a cohort of 15,898 individuals from a Medical Expenditure Panel Survey (MEPS). After a data cleaning procedure, a sample of 9,255 individuals was selected for the inequality part of the study and 2,307 for the exante moral hazard analysis. Propensity score matching with nearest- neighbour and kernel matching algorithms, difference-in-difference models and concentration index, corrected according to Erreygers methodology, were adopted.

Results

The analysis showed that disparities were reduced between social classes although the ex-ante moral hazard is a real problem with the Affordable Care Act since individuals covered by public insurance tended to abuse the public service. Among those who benefited from the Act, a reduction in preventive behaviours was observed: there was an increase in smoking and a decrease in level of physical activity . As far as concerns access to health care, there was a decrease in inequality in emergency visits, inability to get care and getting care when needed among beneficiaries of the reform.

Conclusions

This study demonstrates that the extension of Medicaid has had a dual effect of reducing disparities in access to health care but, at the same time, it seems to have induced people to take less care of themselves.
Effective counting for discrete lattice orbits in the plane via Eisenstein series
Authors: Burrin Claire , Nevo Amos , Rühr Rene , Weiss Barak
Published: May 2021

In 1989 Veech showed that for the flat surface formed by gluing opposite sides of two regular

n

-gons, the set

Y \subset \mathbb{R}^2

of saddle connection holonomy vectors satisfies a quadratic growth estimate

|\{y \in Y: \|y\|\leq R\}| \sim c_YR^2

, and computed the constant

c_Y

. In 1992 he recorded an observation of Sarnak that gives an error estimate

|\{y \in Y: \|y\|\leq R\}| = c_YR^2 + O\bigl(R^{\frac{4}{3}}\bigr)

in the asymptotics. Both Veech's proof of quadratic growth, and Sarnak's error estimate, rely on the theory of Eisenstein series, and are valid in the wider context of counting points in discrete orbits for the linear action of a lattice in

\operatorname{SL}(\mathbb{R})

on the plane. In this paper we expose this technique and use it to obtain the following results. For lattices

\Gamma

with trivial residual spectrum, we recover the error estimate

O(R^{\frac43})

, with a simpler proof. Extending this argument to more general shapes, and using twisted Eisenstein series, for sectors

\mathcal{S}_{\alpha,\beta} = \{r e^{\mathbf{i}\theta} : r>0, \alpha \leq \theta \leq \alpha+\beta\}

we prove an error estimate

\big|\{y \in Y: y \in \mathcal{S}_{\alpha, \beta}, \|y\| \leq R\}\big| = c_Y\frac{\beta}{2\pi} \, R^2 + O_{\varepsilon} \bigl(R^{\frac{8}{5} } \bigr).

For dilations of smooth star bodies

R\cdot B_\psi =\{r e^{\mathbf{i} \theta}: 0 \leq r \leq R \psi(\theta)\}

, where

R>0

and

\psi

is smooth, we prove an estimate

|\{y \in Y: y \in R \cdot B_{\psi}\}|= c_{Y, \psi} R^2 + O_{\psi, \varepsilon}\bigl(R^{\frac{12}{7} }\bigr).
On the discreteness of states accessible via right-angled paths in hyperbolic space
Authors: Lessa Pablo , Garcia Ernesto
Published: May 2021

We consider the control problem where, given an orthonormal tangent frame in the hyperbolic plane or three dimensional hyperbolic space, one is allowed to transport the frame a fixed distance

r>0

along the geodesic in direction of the first vector, or rotate it in place a right angle. We characterize the values of

r>0

for which the set of orthonormal frames accessible using these transformations is discrete. In the hyperbolic plane this is equivalent to solving the discreteness problem (see [Gil2] and the references therein) for a particular one parameter family of two-generator subgroups of

\text{PSL}_2(\mathbb{R})

. In the three dimensional case we solve this problem for a particular one parameter family of subgroups of the isometry group which have four generators.
A relative Sierpinski theorem: Erratum to “Nonhyperbolic Coxeter groups with Menger boundary”
Authors: Haulmark Matthew , Hruska G. Christopher , Sathaye Bakul
Published: May 2021

The purpose of this erratum is to correct the proof of Proposition 2.3 of [HHS]. A classical theorem of Sierpinski states that every subspace of dimension at most one in the 2-dimensional disc

D^2

can be topologically embedded in the Sierpinski carpet. The proof of Proposition 2.3 of [HHS] implicitly provides a relative version of Sierpinski’s theorem. Unfortunately the proof of Proposition 2.3 given in [HHS] is incorrect. We provide two brief proofs that each fill this gap. One is a self-contained argument suited specifically for the needs of [HHS], and in the other we explicitly prove a relative embedding theorem that produces embeddings in the Sierpinski carpet with certain prescribed boundary values.
Tschirnhaus transformations after Hilbert
Authors: Wolfson Jesse
Published: May 2021

In this paper, we use enumerative geometry to simplify the formula for the roots of the general one-variable polynomial of degree

n

, for all

n

. More precisely, let

\mathrm{RD}(n)

denote the minimum

d

for which there exists a formula for the roots of the general degree

n

polynomial using only algebraic functions of

d

or fewer variables. In 1927, Hilbert sketched how the 27 lines on a cubic surface could be used to construct a 4-variable formula for the general degree 9 polynomial (implying

\mathrm{RD}(9)\le 4

). In this paper, we turn Hilbert's sketch into a general method. We show this method produces best-to-date upper bounds on

\mathrm{RD}(n)

for all

n

, improving earlier results of Hamilton, Sylvester, Segre and Brauer.
Nasal polyposis and cystic fibrosis(CF): review of the literature

The aim of this study was to address whether NP might be a predictive factor for severity of CF. The authors collected data from the literature on NP as a unique or associated sign in CF and reviewed the clinical and molecular aspects of CF associated with NP. CF genotypes and clinical severity in NP(+) vs. NP(-) patients were reviewed, taking into account pulmonary function, frequency of P. aeruginosa lung infection, frequency of allergy, nutritional status, and exocrine pancreatic function. The CFTR gene was also analyzed in a patient with isolated severe NP as the unique feature of CF. This review of the literature showed a `milder` phenotype in `NP+` vs. `NP-` CF patients, contrasting with a marked association between NP and `severe` CF mutations. In addition, a complex genotype was identified, associating four heterozygous variants, namely p.Q493X (a severe mutation) on the paternal allele, and p.V562I, p.A1006E, and (TG)11(T)5 (IVS8-5T) on the maternal allele, in a case of CF presenting as isolated NP. The authors speculate that genetic/environmental factors associated with NP might attenuate the functional impact of `severe` CF mutations. The overrepresentation of CF carriers among patients with isolated NP also advocates the need for CFTR molecular screening in such populations for genetic counselling purposes.
Physico-chemical parameters of surface water and sediment of Azuabie creek, Rivers state, Nigeria: a water body receiving abattoir wastes
Authors: Ugbomeh A.P.
Published: May 2021

Physico-chemical parameters were determined in water and sediment samples collected from the Azuabie Creek, Rivers State, Nigeria. This was to establish that run-off from the abattoir affected heavy metals concentrations and other physico-chemistry properties of water. Water samples were collected from 5 stations along Azuabie creek and 3 stations along the Azuabie creek-let, Niger Delta between September 2006 and July 2007. These stations were selected to reflect various points of do-mestic waste inputs into the creek with Station 6 opposite the abattoir as the point source, Stations 1 to 3 within a creek-let that receives run-offs from shore settlers as well as from some industries, and upstream Station 8 as control. Surface water temperature, pH, conductivity, turbidity and salinity were typical of the tropics with spatial and seasonal variations. Total dissolved solids was high especially at Stations 1 to 3 in the creek-let with values above Federal Ministry of Environment maximum limit of 1500 mg/L, indicating an impact from effluents. Essential metals detected in water were iron, copper, zinc and chromium. Non-essential metals in water were arsenic and lead. Nickel, cadmium, vanadium and mercury were below detection limit. Physico-chemical parameters indicated an impact from the abattoir wastes. Principal Component Analysis of surface water and sediment characteristics indicated some stations as distinct on their own from other stations.Key Words: Water quality parameters, heavy metals, abattoir wastes, pollution, PCA analysis, Azuabie creek Physico-chemical parameters of surface water and sediment of Azuabie creek, Rivers state, Nigeria: a water body receiving abattoir wastes
Growth response of Oreochromis niloticus fingerlingsfed fermented Parkia biglobosa diets
Authors: Babalola OA , Onigemo M.A. , Okochi A.N.
Published: May 2021

The study was carried out to determine the growth response of Oreochromis niloticus fingerlings fed fermented Parkia biglobosa (locust beans) diets. P. biglobosa served as an attractant in these diets. Two hundred and twenty-five fingerlings (10.1±0.1 g/fish) mixed sex were treated with five diets containing maize, fishmeal, soyameal, fermented locust beans, bone meal, lysine, methionine, vitamin premix, vitamin C and salt in fifteen replicates and stocked at the rate of 15 fish per unit and reared for twelve weeks. Five experimental diets were formulated at varying levels of inclusion of P. biglobosa at 0% (T1), 2.5% (T2), 5% (T3), 7.5% (T4) and 10% (T5). Results showed that there were significant differences (P<0.01) among the treatments as compared to mean weight gained, feed intake, feed conversion ratio, specific growth rate, protein efficiency, mortality/ survival rate. O. niloticus fed 7.5% inclusion of fermented P. biglobosa had the highest weight gained (30.48 g), highest feed intake (8.86 g) and highest specific growth rate (3.67g). The fish that recorded the highest feed conversion and protein efficiency ratio was the diet with 5% fermented P. biglobosa with mean value of 3.93 g and 2.19 g respectively. Fermented locust beans meal is hereby recommended to be included in the diet of O. niloticus at 7.5% level of inclusion.Key Words: Growth parameters, Parkia biglobosa, attractant, fingerlings, Oreochromis niloticus
