EFFECT OF EARTHWORM’S EXTRACTS (APORRECTODEA MOLLERI) ON YEAST GROWTH: IN VITRO STUDY
Authors: H. Sofia , Yakkou L. , Raouane M. , EL Harti A. , Amghar S.
Published: February 2022

This study was aimed to investigate the effect of earthworms after their decomposition on yeast growth. To achieve this objective, in vitro crude soluble extracts were prepared from two earthworms lots: freshly harvested from the field “FHE” and the other previously starved for one week “SE”. The dry residues of these two crude extracts were used at different concentrations as a solid media for the growth of two yeast species: one “Candida tropicalis” got from another laboratory and the other was isolated by our team from earthworms’ casts “Filobasidium uniguttulatum”, and their growth was evaluated by colonies counting. The results obtained, compared with the Sabouraud Dextrose Agar (SDA), showed that the growth of both yeast isolates was significantly higher on mediums prepared using exclusively earthworms’ crude extracts and agar. Optimal growth was obtained at a concentration corresponding to 0.375g/100 mL of earthworms’ soluble matter of the two types of earthworms’ lots. These results affirmed the richness and the diversification of those extracts, in nutrients and growth factors, that comes mainly from the intrinsic composition of earthworm’s body biomass. The efficiency of the FHE and SE extracts for cultivation of yeast shows their possible use as a culture media that may be applied to other soil microorganisms and even in vivo as soil amendments or biofertilizers.
AN ECONOMIC ANALYSIS OF THE DETERMINANTS OF DOMESTIC DEMAND FOR TEA IMPORTS IN IRAQ USING THE AUTOREGRESSIVE DISTRIBUTED LAG TECHNIQUE (ARDL) FOR THE PERIOD (1990-2020)
Authors: Kadhim Zuhal R.
Published: February 2022

This study was aimed to estimate the domestic demand function on tea imports in Iraq using the Autoregressive Distributed Lag model (ARDL) for co-integration during the period 1990-2020.The data are verified for stationary by using unit root tests basis on Augmented Dickey - Fuller Test. The existence of a long-run equilibrium relationship among tea import quantity, current prices of tea and coffee buying, gross national income, and number of buyers is proved using bounds test method to co-integration. Results of estimating short and long-run models of the demand of tea imports by using the unrestricted error correction approach showed that the error correction parameter is adjusted annually by 140%. Results of estimating price elasticity of demand in the short run showed that the absolute coefficient of price elasticity of demand is less than one and more than zero, which means that tea is a necessary commodity for the Iraqi shopper. Additionally the cross elasticity coefficient had a positive sign in the short and long run, which means that coffee, is an alternative good for tea from the viewpoint of the Iraqi consumer. With regarding to the coefficient value of the income elasticity of demand, it was positive and less than one in the short and long run, which means that tea, is a necessary normal commodity for Iraqi buyers. The study recommended that it is necessary to diversify the sources of national income in the local economy by utilizing all available resources in order to reduce dependence on oil revenues, which were a major source of financing imports in the country.
AN OBSERVATIONAL STUDY TO EVALUATE THE USEFULNESS OF PROCALCITONIN AS A BIOMARKER OF SEPSIS IN THE EARLY STRATIFICATION OF ADULT PATIENTS ADMITTED TO THE INTENSIVE CARE UNIT WITH SUSPECTED INFECTION.

Published: February 2022

Serum Procalcitonin(PCT) has become useful as a biomarker to assist in the diagnosis of sepsis, as well
as related infectious or inammatory conditions. It is a soluble protein liberated into the circulation of
patients in response to severe systemic inammation, in particular by bacterial infection. The aim of this study was to evaluate
the usefulness of Procalcitonin as a biomarker of sepsis in the early stratication of adult patients admitted to the intensive care
unit with suspected infection.Patients are randomly divided into two groups , Group-1: comprising those patients with a
bacterial infection (SIRS with Sepsis) and Group -2: comprising patients without a bacterial infection (SIRS without Sepsis). we
found that elevated PCT concentrations (> 0.5ng/ml) were detected in a signicantly higher proportion of patients with SIRS
with sepsis compared to those with SIRS without sepsis so we concluded that PCT is an excellent marker providing the additive
effect to improve the predictive power for diagnosing sepsis, for assessing severity of sepsis, and also for predicting the
outcome/prognosis.

Contradiction That Never Was: Epigenesis versus Modularity in Evolutionary Aesthetics
Authors: Kiianlinna Onerva
Published: February 2022

Coevolutionary aesthetics has been forming since the early 2010s. Its contribution of great value has been the inclusion of cultural evolution into Darwinian theories on the origins of art and aesthetic judgement. Coevolutionary aesthetics – or non-modular evolutionary aesthetics as it is sometimes called – emphasizes that aesthetic behavior develops in a specific social environment. Coevolutionary aesthetics suggests that traditional evolutionary aesthetics, drawing from evolutionary psychology, has ignored this. The critical position stems from the widely accepted notions that humans adapt plastically to changing conditions and that there is no «innate» aesthetic module in the mind. What has not been examined is that modularity itself is often considered a condition for plasticity of mind. My main argument is that aesthetic inference is a metarepresentational module without direct fitness-increasing functions. Coevolutionary and evolutionary psychological aesthetics are thus more complementary than contradictory. Combining modular and coevolutionary thinking is the most consilient way forward in evolutionary aesthetics.

PRODUCTION AND UTILIZATION OF PULLULANASE FROM BACILLUS CLAUSII FOR ENHANCED RESISTANT STARCH PRODUCTION IN GARRI
Authors: Nwozor Nwanneka , Ogbo Frank
Published: February 2022

Resistant starch is the portion of starch which escapes digestion in the small intestine and passes into the large intestine where it is fermented by gut microflora. It is considered a functional component of food due to the health benefits it confers following its consumption. The aim of this research was to produce garri with high resistant starch using pullulanase enzyme from Bacillus clausii. The organism was isolated from different cassava processing sites in Awka and identified based on phenotypic, biochemical and molecular characteristics. Pullulanase assay was carried out using standard procedures at 540 nm. Optimum conditions for pullulanase production was determined, after which the pullulalanse enzyme was used to modify garri. The test organism with the highest pullulanase activity was identified as Bacillus clausii. Optimum pullulalanse activity was observed with an innoculum size of 3.0ml, pH 6, an incubation temperature of 35o C and incubation time of 48 hours. The resistant starch content was found to be higher for enzyme-treated garri samples (13.81%) than for the untreated garri samples with (2.69%). This research shows that pullulanase enzyme from Bacillus clausii is a very useful industrial raw material for the increased production of resistant starch in foods.

TERRORISM - DEFINING THE PHENOMENON IN POLISH AND FOREIGN RESEARCH
Authors: OLECH Aleksander
Published: February 2022

Zjawisko terroryzmu w swojej destrukcyjnej istocie było zauważalne od zarania dziejów, ponieważ oddziaływało bezpośrednio na podmioty państwowe i niepaństwowe. Jednak scharakteryzowano je dopiero w XX wieku na podstawie aktów agresji, jakich dokonywano w przeszłości. Określono, że są to ataki przeciw jednostce, grupie, państwu lub organizacji międzynarodowej których dokonuje podmiot niepaństwowy. Współcześnie w ogólnej definicji przyjmuje się, że jest to forma walki stosowana dla osiągnięcia określonych celów, z intencją wymuszenia zmian proklamowanych przez terrorystów. Działania są podejmowane przeciwko osobom cywilnym, cechuje je przemoc i agresja, powodują destabilizację, zamieszanie oraz niepokój w społeczeństwie. W związku z powyższym, ta ważne jest przedłożenie opisów zjawiska terroryzmu, które są prezentowane nie tylko przez polskich badaczy, ale także francuskich (Francja najbardziej atakowane państwo w Unii Europejskiej) oraz w ujęciu międzynarodowym.

Published: February 2022

Celem artykułu jest wykazanie bezpośrednich związków specyficznej formy przestępstw politycznych określanych jako zdrada stanu z bezpieczeństwem państwa polskiego. Zasadnicza hipoteza będąca podstawą analizy zawiera się w stwierdzeniu, że czyny godzące w rację stanu oraz istotę podwalin ustrojowych państwa polskiego uznaje się za zagrożenie dla jego bezpieczeństwa i dlatego są one karnie ścigane jako zdrada stanu. Cel szczegółowy dotyczy ukazania ewolucji podejścia do tego problemu w ujęciu historycznym oraz podkreślenia wagi zagrożenia zdradą stanu dla bezpieczeństwa współczesnej Polski. Podstawowymi metodami zastosowanymi przez autorów była metoda historyczna oraz metoda analizy prawnej. Ich użycie pozwoliło wyspecyfikować węzłowe kwestie w podejściu do zdrady stanu w przeszłości oraz przedstawić jej postrzeganie z perspektywy obecnie obowiązujących przepisów polskiego prawa karnego. W rezultacie przeprowadzonych analiz ustalono, że zdrada stanu to najpoważniejsze przestępstwo wobec państwa godzące w jego bezpieczeństwo wewnętrzne i zewnętrzne. Negatywne konsekwencje jakie rodzi dla bezpieczeństwa państwa dokonanie zdrady stanu zostały sklasyfikowane w postaci skutków polityczno-ustrojowych, militarnych oraz ekonomicznych.
On the Dichromatic Number of Surfaces
Authors: Aboulker Pierre , Havet Frédéric , Knauer Kolja , Rambaud Clément
Published: February 2022

In this paper, we give bounds on the dichromatic number  $\vec{\chi}(\Sigma)$ of a surface $\Sigma$, which is the maximum dichromatic number of an oriented graph embeddable on $\Sigma$. We determine the asymptotic behaviour of $\vec{\chi}(\Sigma)$ by showing that there exist constants $a_1$ and $a_2$ such that, $ a_1\frac{\sqrt{-c}}{\log(-c)}   \leq \vec{\chi}(\Sigma) \leq  a_2  \frac{\sqrt{-c}}{\log(-c)} $ for every surface $\Sigma$ with Euler characteristic $c\leq -2$. We then give more explicit bounds for some surfaces with high Euler characteristic. In particular, we show that the dichromatic numbers of the projective plane $\mathbb{N}_1$, the Klein bottle $\mathbb{N}_2$, the torus $\mathbb{S}_1$, and Dyck's surface $\mathbb{N}_3$ are all equal to $3$, and that the dichromatic numbers of the $5$-torus $\mathbb{S}_5$ and the $10$-cross surface $\mathbb{N}_{10}$ are equal to $4$. We also consider the complexity of deciding whether a given digraph or oriented graph embeddable on a fixed surface is $k$-dicolourable. In particular, we show that for any fixed surface, deciding whether a digraph embeddable on this surface is $2$-dicolourable is NP-complete, and that deciding whether a planar oriented graph is $2$-dicolourable is NP-complete unless all planar oriented graphs are $2$-dicolourable (which was conjectured by Neumann-Lara).

Agritourism Farms: A Great Way to Promote Local Products
Authors: Fanelli Rosa Maria
Published: February 2022

Online communication (Web 2.0) is an important tool that can assist consumers in choosing a service and/or buying a product and, if used effectively, can help businesses to improve organizational performance. This is a study of the websites of a sample of 4,080 Italian agritourism farms,
which focuses on the construction, utility, and relative maturity of these businesses. The study entails an exploration of how and where the organization of websites is effective for the promotion of the features of agritourism farms and is therefore essential for providing recommendations
for decisionmakers in the Italian agritourism sector. To test the study hypotheses, an extended model of internet commerce adoption (eMICA) is used, which is adapted to include the information reported on each agritourism farm website. Chi-square automatic interaction detection (CHAID) helps
to analyze the differences in website design and vacation types on offer at the provincial level. The eMICA highlights the utility of using interactivity to measure the relative maturity of agritourism farm websites. In contrast, the CHAID decision tree shows how the diversification of vacation
types is an important strategy for selling local agrifood products, especially to farm accommodation guests.

Published: February 2022

In this short note, we consider interval estimation for the parameters under the uniform distribution U(a; b). We study two approaches: (1) based on a Wald-type statistic, (2) based on a pivotal statistic. We show that the first approach in its common form is not valid and we propose a modified version of the first approach. It turns out it is equivalent to the confidence interval with the shortest length.
Sobre el denominado tan(to) demostrativo en español
Authors: Devís Márquez P. Pablo
Published: February 2022

Suele establecerse en la gramática del español una dicotomía entre un tan(to) demostrativo, pero no comparativo, y un tan(to) comparativo. Son objetivos de este trabajo demostrar la no pertinencia de esta distinción, presentar el denominado tan(to) demostrativo no comparativo como resultado de la mera elisión del segundo constituyente del cuantificador comparativo de igualdad “tan(to) + coda”, establecer las condiciones contextuales y/o situacionales que permiten la supresión de la coda, y asumir la imposibilidad de elidir el constituyente tan(to) en el cuantificador comparativo.

Using imaging and radio multi-wavelength observations, we studied the origin of two homologous accelerated electron beams and a quasiperiodic fast-propagating (QFP) wave train associated with a solar jet on 2012 July 14. The jet occurred in a small-scale fan-spine magnetic system embedded in a large-scale pseudostreamer associated with a GOES C1.4 flare, a jet-like coronal mass ejection (CME), a type II radio burst, and a type III radio burst. During the initial stage, a QFP wave train and a fast-moving on-disk radio source were detected in succession ahead of the jet along the outer spine of the fan-spine system. When the jet reached a height of about 1.3 solar radii, it underwent a bifurcation into two branches. Based on our analysis results, all the observed phenomena in association with the jet can be explained by using a fan-spine magnetic system. We propose that both the type III radio burst and the on-disk fast-moving radio source were caused by the same physical process, i.e., energetic electrons accelerated by magnetic reconnection at the null point, and these energetic electrons were propagating along the open field lines of the pseudostreamer and the closed outer spine of the fan-spine structure, respectively. Due to the bifurcation of the jet body, the lower branch along the closed outer spine of the fan-spine structure fell back to the solar surface, while the upper branch along the open field lines of the pseudostreamer caused the jet-like CME in the outer corona.
Thermophysical Investigation of Asteroid Surfaces. II. Factors Influencing Grain Size
Authors: MacLennan Eric M. , Emery Joshua P.
Published: February 2022

Asteroid surfaces are subjected to mechanical weathering processes that result in the development and evolution of regolith. Two proposed mechanisms—impact bombardment and thermal fatigue—have been proposed as viable and dominant weathering processes. Previously, we compiled and estimated thermal inertias of several hundred asteroids (mostly in the main belt) for which we determined dependencies on temperature, diameter, and rotation period. In this work, we estimate grain sizes of asteroid regoliths from this large thermal inertia data set using thermal conductivity models. Following our previous work, we perform multivariate linear model fits to the grain size data set and quantify its dependency on diameter and rotation period. We find that the preferred model indicates that asteroid grain sizes are inversely dependent on object size for <10 km asteroids and exhibit no relationship above this size cutoff. Rotation period and grain size show a positive relationship when the rotation period is greater than ∼5 hr and an inverse relationship below this rotation period. These results indicate that both impact weathering and thermal fatigue are relevant regolith evolution mechanisms. We run post-hoct-tests between spectral groups to infer the influence of composition on regolith grain sizes. We find that M-type (including suspected metal-rich objects) and E-type asteroids have larger grain sizes relative to our population sample and that P-type asteroids have distinctly smaller grains than other groups.
High-resolution Search for Kuiper Belt Object Binaries from New Horizons

Using the New Horizons LOng Range Reconnaissance Imager camera, we searched for satellites near five Kuiper Belt objects (KBOs): four cold classicals (CCs: 2011 JY31, 2014 OS393, 2014 PN70, 2011 HZ102) and one scattered disk (SD) object (2011 HK103). These objects were observed at distances of 0.092–0.290 au from the New Horizons spacecraft, achieving spatial resolutions of 136–430 km (resolution ∼2 camera pixels), much higher than possible from any other facilities. Here we report that CC 2011 JY31 is a binary system with roughly equal brightness components, CC 2014 OS393 is likely an equal-brightness binary system, while the three other KBOs did not show any evidence of binarity. The JY31 binary has a semimajor axis of 198.6 ± 2.9 km, an orbital inclination of 61.°34 ± 1.°34, and an orbital period of 1.940 ± 0.002 days. The OS393 binary objects have an apparent separation of ∼150 km, making JY31 and OS393 the tightest KBO binary systems ever resolved. Both HK103 and HZ102 were detected with a signal-to-noise ratio (S/N) ≈ 10, and our observations rule out equal-brightness binaries with separations larger than ∼430 km and ∼260 km, respectively. The spatial resolution for PN70 was ∼200 km, but this object had a S/N ≈ 2.5–3, which limited our ability to probe its binarity. The binary frequency for the CC binaries probed in our small survey (67%, not including PN70) is consistent with the high binary frequency suggested by larger surveys of CCs and recent planetesimal formation models, but we extend the results to smaller orbit semimajor axes and smaller objects than previously possible.

Abstract
BACKGROUND: Experimental data on the effect of a high dose of gamma radiation 6 Gy on the activity of antioxidant defense enzymes and lipid peroxidation products (LPO) are presented immunocompetent organs in the body of animals in the experiment. It was found that the effect of ionizing radiation led to an increase in the level of diene conjugates (DC) and malondialdehyde (MDA), inhibition of the activity of catalase (CАT) and glutathione peroxidase (GlP), glutathione reductase (GlR) enzymes in almost all the studied objects, as a result of which the development of oxidative stress was observed in them. The results of the study indicate serious changes in the lipid peroxidation and antioxidant system (AOS) under radiation stress. An imbalance of POL-AOS creates prerequisites for the occurrence of immunopathological conditions, contributing to the development of radiation-related tumor infection. pathologies. Violations of functional relationships of the catalytic redox system.
AIM: The aim of the study was to study the effect of radiation at a dose of 6 Gy on the parameters of lipoperoxidation and the antioxidant system in experimental rats.
MATERIAL AND METHODS: The work was carried out on 20 male Wistar rats weighing 240 ± 20 g. Experimental animals are divided into two groups: I - normal group; II - group exposed to γ-rays at a dose of 6 Gy.
RESULTS: After radiation exposure, all objects showed a tendency to increase the product of lipid peroxidation. As is known, the activation of lipid peroxidation is based on excessive generation of reactive oxygen species, which exceeds the physiological capabilities of antioxidant systems that occur after the depletion of enzyme systems.
CONCLUSION: Based on the results obtained, it was found, that irradiation increases the intensity of the formation of POL products and their accumulation, reduces the activity of enzymes of the antioxidant system in immunocompetent organs in irradiated animals, as a result, the lack of the antioxidant system causes oxidative stress in the body.

Anatomic Repair of Deltoid Ligaments in Acute Injury With Suture Anchor Technique
Authors: Xiao Kai , Xie Wei , An Ying
Published: February 2022

Acute disruption of the deltoid ligament usually occurs in rotational ankle fracture. If left untreated, its instability may contribute to ankle arthritis. We have designed a suture technique to repair all deltoid ligament layers. It provides anatomic ligament-to-bone repair of the superficial and deep deltoid ligaments and anchor suture reinforcement. This technique may protect the horizontally oriented fibers of the deep deltoid ligaments and allow them to heal with sufficient rest while providing immediate stability of the construct. The superficial ligaments are then repaired with residual anchor sutures. [
