Authors: Lokanan Mark , Chopra Gaurav
Published: March 2021

Money laundering is a defiance of law and order within the real estate (RE) sector in Canada. Laundering of illicit funds impacts the stability, reliability, and integrity of the government, financial institutions, and the economic sectors. Due to its mysterious nature, there are more unknowns about the quantum of snow washing in the property market or its effects on price inflation. Using data from the Cullen Commission about money laundering in Canada, this chapter is an effort to examine the nuances that law enforcement encounters while investigating illegal investment operations. This chapter illuminates a broad range of problems around the investigations of unlawful investments and recommends pragmatic solutions to the illicit flow of money in RE sector of Canada.

Authors: Marcone Maria Rosaria
Published: March 2021

This research focuses on supply chain performance measurement systems (SCPMSs) and its purpose is to offer the most appropriate managerial practices that can help innovative firms that want to improve their performance in dynamic competitive contexts, reconfiguring internal products/processes and repositioning their supply in modern, innovative, and recently-established international production chains, which moreover are very different from the supply chains to which they belong. This is ongoing research, and, in this paper, it is intended to present the first cognitive results, still being studied and evaluated. The research focuses on a sample of 20 study cases, and its aim is to detect if small and medium-sized firms (SMEs) that innovate efficiently benefit from enhanced competitiveness. As far as the methodology adopted is concerned, the qualitative analysis of the cases was carried out with an inductive method. The 20 study cases belong to the fashion, mechatronics, automotive, and packaging systems, and they have been investigated as real research laboratories for 6 years. The first results suggest that there might be a close relationship between innovation, efficiency, and firm performance. In addition, many innovations are technology-driven and related, for instance, to business model re-configuration. This paper aims to benefit both practice and theory.

Published: March 2021

In the present research, attempts have been made to weld 18 mm thick AISI 409 ferritic steel plate in a single pass with electron beam welding process. The welded joint was investigated for macrostructure, microstructural, microhardness, impact toughness, and tensile strength. The coarse ferritic grains of base metal were converted into fine equiaxed and columnar grains in the weld zone. The microhardness results revealed that for fusion zone and heat affected zone had 28% and 41% higher microhardness than the base metal. Further, post weld heat treatment at 550ºC/75 minutes resulted in 5% rise in ultimate tensile strength, 10% rise in yield strength, and 31% rise in impact toughness as compared to as welded specimens. The fractography of impact and tensile specimens revealed brittle mode of fracture and changed to ductile mode after post weld heat treatment.

Authors: Duchowicz Pablo Roman , Fioressi Silvina , Romanelli Gustavo , Bacelo Daniel E.
Published: March 2021

This work applied the quantitative structure-activity relationships (QSAR) theory to predict the inhibitory activity exhibited by 40 unsymmetrical aromatic disulfide compounds against the SARS-CoV main protease. Different freely available molecular descriptor programs provided 67,116 independent non-conformational molecular descriptors. This great number of descriptors contained multidimensional representations of the chemical structure and was analyzed through multivariable linear regressions and the replacement method variable subset selection technique. The developed QSAR model achieved an acceptable statistical quality and provided a prospective guide that was considered useful for predicting the inhibitory activity of structurally-related aromatic disulfide compounds on the SARS-CoV main protease.

Authors: Baporikar Neeta , Fotolela Rosalia
Published: March 2021

Entrepreneurship and development of entrepreneurship have been the focus of all economies, but more so of emerging economies. However, there are many barriers including social and cultural aspects in entrepreneurship development. This has resulted in entrepreneurship's mono-dimensional look. Yet, in reality, a person who deals with the creation of the neo-ideas has social and cultural aspects like family characteristics, customs, community, the rate of participation in society that can aid or be a detriment in becoming successful entrepreneurs leading to sustainable entrepreneurship development. Hence, adopting a qualitative exploratory approach using semi-structured in-depth interviews of 30 SME owner-managers of Namibia, the aim of this study is to understand the role of social and cultural facets for sustainable entrepreneurship development. Findings show that social factors in entrepreneurship emerged and grabs the benefits of new concepts to make progress where social justice has raised barriers, and the cultural factors influence entrepreneurs and social behaviors of practice.

Published: March 2021

This paper investigates the effect of partial replacement of fly ash with sago pith waste ash and silica fume in fabricating the geopolymer mortar concrete. The mixtures of geopolymer mortar concrete were prepared by replacing sago pith waste ash and silica fume at 5% of total weight of fly ash. There were six specimens of geopolymer mortar cubes and bricks fabricated in this study. The specimens are tested with compressive strength test, rebound hammer test and ultrasonic pulse velocity test. The results from the tests are compared with some existing published works as to clarify the effect of replacing the fly ash with sago waste and silica fume on the strength of concrete. Comparisons had been made and concluded that the molarity of alkaline solution, Al3O2 and CaO influenced the development of compressive strength along the curing time of fly ash based geopolymer concrete.

The models are predicting and analyzing on compressive and flexural testing by considering fiber reinforcement embedded in confinement concrete. In this work, steel 4340 fiber with high aspect ratio was developed in unique random spline shape and randomly disperse in confinement concrete. Fibers designed in 15.5mm of average length and amount were varied in range of 50 to 200 and 250 to 1000 for compressive and flexural testing, respectively. Both varied orientation and random dispersion of fiber were developed using MATLAB before embedded and analyzed in Ansys Workbench. The finite element model was validated in initial results on plain concrete prior study in influence of confining and fibers to structure. The model proposed showed that confining reinforcement increasing ductility and large deflections in structure testing. In addition, fibers as reinforcement slightly increases in strength for both compressive and flexural in certain number. These method reinforcement was help warning of failure prior to complete failure that use in construction material.

Published: March 2021

Around 1000 million waste tyres are generated annually and over 5000 million more are estimated to be discarded by 2030. It is estimated that one waste tyre is discarded per person in developed areas, hence 1 billion waste tyres are disposed worldwide. Waste tyre is difficult to manage as it takes up space, is difficult to compress and combustion of tyre releases highly toxic substance into the air. Hence, most of them end up in the landfill, as past research data estimated that currently 4 billion waste tyres can be found in landfills. In this study, up to 30% tyre rubber with a fine grind size of 300nm to 500nm was used as partial sand replacement in type N cement mortar. The rubber was treated with 1M NaOH solution to enhance its ability to bond with the other constituent materials. Tests were conducted to determine the properties of rubberised mortar, including consistency, compressive strength, flexural strength, water absorption and acid attack. From the test result, tyre rubber reduced the consistency and strength of mortar. Mathematical regression model showed that reduction of strength occurred in a second-order polynomial function with percentage of rubber. It was concluded that at up to 20% replacement rubberised mortar has the best resistance against water absorption and acid attack while still achieving the target strength.

Published: March 2021

Soft marine clay soil is characterized with highly compressible behavior, in which associated with poor bearing capacity and low in shear resistance. Soil improvement works are carried out to reduce the soil failure and destruction to the superstructure. Various techniques available for soil stabilization including the use of admixture to improve the engineering properties of the problematic soil. This paper aims to report on the use of waste steel dust retrieved from the medication supply industry as soil stabilization agent. Several series of Atterberg limit test and Unconfined Compressive Test were carried out to foresee the potential use of the waste steel dust for the purpose of civil engineering applications. The significant findings from this study is evident that the waste steel dust ranges from 5% to 15% did not able to serve as soil stabilization agent. It can reduce the plastic behavior of the soil sample; however, it also caused the strength of the soil declined. In comparison with previous studies, the presence of activated agent could possibly enhance the performance of waste steel dust as an alternative treatment agent to soil improvement works. The use of activated agent is to serve as pozzolanic materials to create cementitious bonding in between the soil interparticles matrix.

Published: March 2021

Herein, we compared thermal desorption analysis (TDA) curves obtained by conducting experiments and simulations. In addition, we discussed the validation of our simulations and trapping sites of hydrogen atoms. In as-received F82H, when the samples contained solute atoms, grain boundaries, dislocations, and precipitates, the experimental curve corresponded to the simulated curve. In positron annihilation lifetime (PAL) measurements, di-vacancies were detected in the electron-irradiated F82H. When we changed the growth and the concentration of vacancy-type defects during temperature increase using the rate theory, the simulation results agreed with experiment results. In creep-ruptured Fe, only dislocations were detected by the PAL measurements. However, the existence of a type of defect, which was related to grain boundaries, must be assumed to fit the simulation curve to the experimental one. In the next step, the diffusion of hydrogen atoms on grain boundaries should be added to simulation program.

Authors: Wacharawichanant Sirirat , Opasakornwong Patteera , Poohoi Ratchadakorn , Phankokkruad Manop
Published: March 2021

This work studied the effects of medium-length fibrous cellulose (MFC) on the morphology, mechanical and thermal properties of poly(lactic acid) (PLA)/propylene-ethylene copolymer (PEC) (90/10) blends. The morphological analysis of PLA/MFC composites observed MFC fibers inserted in the PLA matrix and MFC appeared agglomeration when added high MFC loading. The phase morphology showed the two-phase separation of PLA/PEC blends. The presence of PEC reduced the agglomeration of MFC fibers in polymer matrix. The tensile stress and strain curves found that the ultimate stress of PLA was the highest value and the addition of MFC increased Young’s modulus of PLA/MFC and PLA/PEC/MFC composites. The PEC presence improved the strain at breaking point of PLA/PEC blends. The thermal properties found that the incorporation of MFC did not improve the thermal stability of PLA/MFC and PLA/PEC/MFC composites due to the PLA had degradation temperature higher than MFC.

Published: March 2021

The freshwater angelfish, Pterophyllum scalare like many other cichlids show parental care of embryos and larvae. This study was carried out to investigate the embryonic development of P. scalare, which shows biparental care and substrate brooding. During the study adult reproductive behavior and parental care was observed. Once the eggs were fertilized upon spawning, the early and later embryonic stages were observed, documented and various embryo length measurements were analyzed to characterize the developmental pattern in this species. Whole mounts and bone and cartilage measurements of acid free double stained larvae were analyzed to further understand the developmental rates in the hatched larvae. The developmental events were compared with those of other documented cichlid species as well as with the zebrafish, Danio rerio (Family Cyprinidae), which does not show parental care. After fertilization, cleavage division of the P. scalare embryo starts 1.30 hours post fertilization (hpf). On average, cleavage, blastula, gastrula, segmentation and pharyngula periods of embryogenesis are observed for approximately 3 ½, 11 ½, 9 ½, 36 and 12 hours respectively. Ultimately, P. scalare embryos hatched around 72 (hpf). Head Length, dorsal, caudal and anal fins show positive allometric growth while body depth and digestive tract show almost isometric growth. The study highlights that similar to a few other studied cichlids, P. scalare embryogenesis and larval development occur at a slower rate of development compared to D. rerio. In cichlids including P. scalare, parental care may allow these embryos the luxury of developing at a slower rate whereas the lack thereof for D. rerio embryos may necessitate faster development.

Derived Beilinson–Flach elements and the arithmetic of the adjoint of a modular form
Authors: Rivero Óscar , Rotger Victor
Published: March 2021

Kings, Lei, Loeffler and Zerbes constructed in [LLZ], [KLZ1] a three-variable Euler system

\kappa(\textbf{g},\textbf{h})

of Beilinson–Flach elements associated to a pair of Hida families

(\textbf{g},\textbf{h})

and exploited it to obtain applications to the arithmetic of elliptic curves, extending the earlier work [BDR]. The aim of this article is to show that this Euler system also encodes arithmetic information concerning the group of units of the associated number fields. The setting becomes specially novel and intriguing when

\textbf{g}

and

\textbf{h}

specialize in weight 1 to

p

-stabilizations of eigenforms such that one is dual to the other. We encounter an exceptional zero phenomenon which forces the specialization of

\kappa(\textbf{g},\textbf{h})

to vanish and we are led to study the derivative of this class. The main result we obtain is the proof of the main conjecture of [DLR4] on iterated integrals and the main conjecture of [DR1] for Beilinson–Flach elements in the adjoint setting. The main point of this paper is that the methods of [DLR1], [DLR4] and [CH], where the above conjectures are proved when the weight 1 eigenforms have CM, do not apply to our setting and new ideas are required. In the previous works, a crucial ingredient is a factorization of

p

-adic

L

-functions, which in our scenario is not available due to the lack of critical points. Instead we resort to the principle of
improved
Euler systems and

p

-adic

L

-functions to reduce our problems to questions which can be resolved using Galois deformation theory. We expect this approach may be adapted to prove other cases of the Elliptic Stark Conjecture and of its generalizations that appear in the literature.
A two-variable series for knot complements
Authors: Gukov Sergei , Manolescu Ciprian
Published: March 2021

The physical 3d

\mathcal N = 2

theory

T[Y]

was previously used to predict the existence of some

3

-manifold invariants

\widehat{Z}_{a}(q)

that take the form of power series with integer coefficients, converging in the unit disk. Their radial limits at the roots of unity should recover the Witten–Reshetikhin–Turaev invariants. In this paper we discuss how, for complements of knots in

S^3

, the analogue of the invariants

\widehat{Z}_{a}(q)

should be a two-variable series

F_K(x,q)

obtained by parametric resurgence from the asymptotic expansion of the colored Jones polynomial. The terms in this series should satisfy a recurrence given by the quantum A-polynomial. Furthermore, there is a formula that relates

F_K(x,q)

to the invariants

\widehat{Z}_{a}(q)

for Dehn surgeries on the knot. We provide explicit calculations of

F_K(x,q)

in the case of knots given by negative definite plumbings with an unframed vertex, such as torus knots. We also find numerically the first terms in the series for the figure-eight knot, up to any desired order, and use this to understand

\widehat{Z}_a(q)

for some hyperbolic 3-manifolds.
Asymptotic estimates for the largest volume ratio of a convex body
Authors: Galicer Daniel , Merzbacher Mariano , Pinasco Damián
Published: March 2021

The
largest volume ratio
of a given convex body

K \subset \mathbb R^n

is defined as

\mathrm{lvr}(K):= \mathrm {sup}_{L \subset \mathbb R^n} \mathrm {vr}(K,L),

where the sup runs over all the convex bodies

L

. We prove the following sharp lower bound:

c \sqrt{n} \leq \mathrm{lvr}(K),

for
every
body

K

(where

c > 0

is an absolute constant). This result improves the former best known lower bound, of order

\sqrt{{n}/{\log \log(n)}}

.

We also study the exact asymptotic behaviour of the largest volume ratio for some natural classes. In particular, we show that

\mathrm{lvr}(K)

behaves as the square root of the dimension of the ambient space in the following cases: if

K

is the unit ball of an unitary invariant norm in

\mathbb{R}^{d \times d}

(e.g., the unit ball of the

p

-Schatten class

S_p^d

for any

1 \leq p \leq \infty

), if

K

is the unit ball of the full/symmetric tensor product of

\ell_p

-spaces endowed with the projective or injective norm, or if

K

is unconditional.

The foraging efficiency of birds may vary according to local conditions as a result of the balance between energy consumption and expenditure. The foraging efficiency of Egretta thula (adults n=11) and Egretta caerulea (adults n=69 and juveniles n= 17) was compared in Paranaguá city estuary, in Paraná, Brazil. In 14 hours of observation divided into 2 minutes sessions per individual, were recorded foraging site (mud or shallow water), number of steps, total peckings and successful peckings, and were calculated the success rates, energy effort and capture efficiency. In shallow water E.thula was more efficient than E. caerulea. There was no intraspecific differences in E. thula regarding environments. Adults of E. caerulea were more efficient than juveniles, with greater efficiency in mud than in shallow waters environments. Differences in foraging efficiency between species may be related to the type of foraging according to feeding location.

Phytoplankton is an important model of the aquatic environments functioning, responding directly to environmental variability in space and time. Therefore, represents an excellent tool for the monitoring of reservoirs, which comprise highly heterogeneous ecosystems longitudinally, influencing the structure and distribution of phytoplankton species. The objective of this study was to investigate the variation in the composition and biomass of the phytoplankton in a reservoir in the Goiás state, Brazil, and how these organisms respond to environmental variability along the reservoir spatial extent in dry and rainy periods. The phytoplankton and environmental variables were collected during one dry period and other rainy, over seven sampling sites, distributed in the regions downstream of the dam, lacustrine, intermediate and lotic of the reservoir. The composition and biomass of the phytoplankton community were measured as a response to the spatial and temporal environmental variability. We recorded a spatio-temporal variation in water temperature, light, nutrients, and phytoplankton biomass. Cyanobacteria had the highest biomass in the lacustrine and intermediate regions, while diatoms in the lotic region, in both periods. The highest phytoplankton total biomass was recorded in rainy period. We recorded a clear relation between the phytoplankton biomass and the environmental variability, being that water temperature, turbidity and soluble iron the ones that showed the biggest influence on the biomass structure. Thus, the composition and biomass of the phytoplankton community can be important metrics of reservoirs functioning and, therefore, the phytoplankton study in these ecosystems it's of interest in their monitoring, since reservoirs have great ecological, economic or public health relevance

Macrophytes are plant organisms that live partially or totally submerged in water, being fixed and free. The Doce River is one of the main rivers in southeastern Brazil and, in 2015, it was hit by ore tailings from the Fundão dam burst in Mariana, Minas Gerais. This work aims to provide a floristic survey of macrophytes in the lower Doce River basin and to compare the species composition between lentic and lotic environments. Expeditions were carried out monthly from October 2018 to September 2019, in five stations in lotic and six in lentic environments. A total of 105 species belonging to 33 families of vascular plants were recorded, among them 14 are new occurrences for Espírito Santo state. Richest families were Poaceae (23 spp.) and Cyperaceae (22 spp.). Amphibious/emerging plants were the most representative (46 spp.). NMDS analysis revealed that the composition of the lotic and lentic environments are different.

Streams are environments that are very affected by human activities such as pollution, deforestation of riparian forests and introduction of exotic species. In this context, it is important to know its biodiversity for monitoring and conservation. The present study inventoried the fish fauna of three tributary streams of the Jacarezinho River (Cinzas River basin, Paranapanema River) with different environmental characteristics: Água dos Anjos, Monjolinho and Ubá streams. Quarterly collections were performed in the period between October 2012 and July 2013 at the headwaters, in the middle and at the mouth of each stream, using electrofishing. We analyzed the parameters of species richness, total abundance, relative abundance, capture constancy, rarefaction curves of Coleman, and richness estimators ACE and ICE. We captured a total of 7102 individuals, distributed in six orders, 12 families and 33 species. The most abundant order was Characiformes (76.15 %), while the most abundant species were: Bryconamericus iheringii (39.5 %), Astyanax bockmanni (19.36 %), and Geophagus brasiliensis (7.52 %). The highest species richness was found in Água dos Anjos stream (26), followed by Monjolinho stream (25), and the Ubá stream (15). We recorded the occurrence of four non-native species (Bryconamericus exodon, Gymnotus inaequilabiatus, Poecilia reticulata and Oreochromis niloticus), which represent a risk to the biodiversity of the studied streams. The Ubá stream was considered the most conserved, but the presence of P. reticulata shows that it has also suffered from anthropic impacts. This non-native species is constantly associated to degraded environments, mainly when it occurs in high abundance. Our results suggest that the fish assemblages studied present different structures, probably due to the interaction among historical, abiotic, biotic, and anthropic factors. This study has been carried out for the first time in the Cinzas River basin and can help provide theoretical input for the elaboration of monitoring and conservation plans.

Published: March 2021

Despite estimates suggesting Leptospira spp. being endemic in Southeast Asia, evidence remains limited. Diagnostic accuracy evaluations based on Leptospira ELISA mainly rely on hospitalized and severe patients; therefore, studies measuring the pathogen burden may be inaccurate in the community. We evaluated the Panbio Leptospira ELISA IgM among 656 febrile outpatients attending primary care in Chiangrai, Thailand, and Hlaing Tha Yar, Yangon, Myanmar. ELISA demonstrated limited diagnostic accuracy for the detection of acute leptospiral infection using the manufacturer recommended cutoff, with a sensitivity of 71.4% and specificity of 36.4%, and an area under the receiver operator characteristic curve value of 0.65 (95% CI: 0.41–0.89), compared with our reference test, the PCR assay. ELISA also performed poorly as a screening tool for detecting recent exposure to Leptospira spp. compared with the “gold-standard” microscopic agglutination test, with a specificity of 42.7%. We conclude that the utility of the Leptospira IgM ELISA for both serodiagnosis and seroprevalence is limited in our setting.

An online survey was distributed in 2019 via social media, professional groups, and snowball sampling to TNB persons, who were current residents or recent graduates (within the past 3 years) of a US residency program.

Results

Twenty-six eligible respondents from 10 medical specialties completed the survey. Eighteen (69.2%) respondents felt unsafe disclosing their gender identity or discussing it during interviews some or all of the time due to fear of discrimination and how it might affect their match; 26.9% (7 of 26) felt they were ranked lower than their qualifications due to their gender identity. Eleven (42.3%) were misnamed or misgendered some or all of the time during interviews through use of incorrect name and pronouns. Respondents' recommendations for programs included: (1) adopt gender-affirming practices; (2) offer gender-affirming health benefits; (3) advertise nondiscrimination policies; (4) understand experiences of discrimination during medical training; and (5) value resident gender diversity.

Conclusions

TNB residents and recent graduates perceived gender identity discrimination during residency application, including feeling unsafe to disclose their gender identity and being misnamed or misgendered. Suggestions for programs to improve the experience of TNB applicants are included.

Published: March 2021

Studies have attributed project failure to poor communication management. This research assessed the impact of communication management on the delivery of construction projects in Abuja, with a view to proposing strategies for improving communication management. The quantitative research method was adopted for the study. Data collection was done through questionnaire survey. Analysis of data was carried out using Mean Item Score (MIS) and Relation Importance Index (RII). Results of the study revealed that the most important causes of poor communication management on construction projects range from Poor feedback (RII = 0.89) to Lack of training (RII = 0.82). The influence of communication management on the cost (MIS = 3.80-4.55), time (MIS = 3.83-4.50) and quality (MIS = 3.53-4.25) delivery of construction projects is significant. Based on these findings, it was concluded that the impact of communication management on the delivery of construction projects in Abuja is significant. It was recommended that project managers should avoid the major causes of poor communication management which range from “Ineffective communication channel used” to “Lack of training” in order to minimise potential dispute, misunderstanding and project failures as a result of poor management of communication on project sites.

Influence of sensorineural hearing loss on familiar speaker recognition: A forensic perspective on ageing
Authors: Kudera Jacek
Published: March 2021

The main goal of this research was to discover the influence of high frequency sensorineural hearing loss on familiar speaker recognition during earwitnessing line-ups. The secondary objectives were to estimate the influence of familiarity with voices of the suspects on performance in the auditory speaker recognition test, and to correlate the results with forensically important factors such as a confidence scale from the line-up markings. The recordings from the line-up sessions were low-pass filtered to ensure an equal degree of signal distortion for all subjects and imitate the moderate, severe and profound hearing loss conditions. The results show that the correlation between mimicked hearing impairment and ability to identify a familiar speaker is statistically significant. It was observed that higher degree of signal distortion caused lower accuracy of recognition. Interestingly, it was reported that higher levels of familiarity and exposure to speakers’ voices had a negative effect on speaker identification.
Autolycus and Sisyphus – Some Words about the Category of Trickster in Ancient Mythology
Authors: Dominas Konrad
Published: March 2021

The goal of this article is to juxtapose the trickster model suggested by William J. Hynes in the text Mapping the Characteristics of Mythic Tricksters: A Heuristic Guide with the stories of Sisyphus and Autolycus. A philological method proposed in this article is based on a way of understanding a myth narrowly, as a narrative with a specific meaning, which can be expressed in any literary genre. According to this definition, every mythology which is available today is an attempt at presenting a story of particular mythical events and the fortunes of gods and heroes. Therefore, stories about Sisyphus and Autolycus are myths that have been transformed and which in their essence may have multiple meanings and cannot be attributed to one artist. The philological method is, in this way, based on isolating all fragments of the myth relating to the above protagonists and subsequently presenting them as a coherent narrative.
The Archetype of the Trickster in the Writings of C.G. Jung
Authors: Błocian Ilona
Published: March 2021

Jung dealt with the concept of the trickster archetype in many of his works. References to his interpretations of the impact of this archetype and the myths associated with this figure are also scattered in many places of his works devoted to various issues. The notion of the archetype is extremely complex in his grasp, and the ways of understanding it are evolving, similarly to the concept of the unconscious. These evolutions are related to the transition from the plan of patterns of individual human development, to the development of the species, to the recognition of the very patterns of the development of reality, so they contain references to the psychological, anthropological, and philosophical levels. According to Jung, the trickster archetype expresses –i n the most general terms –the conflict of these patterns, which introduces a certain factor to the development process that is both disharmonizing and dynamizing at the same time.
Historical and contemporary transformations of the hydrographic confluence at Sielpia

Published: March 2021

Making use of the cartographic-geomorphological method, a case study of the hydrographic confluence at Sielpia made it possible to identify changes in the river and hydrographic networks connected with the development and decline of the Old Polish Industrial District, whose functioning relied on the use of hydropower in iron metallurgy. The formation and disappearance of artificial industrial reservoirs and canals, the drainage networks, and the appearance of catastrophic flash floods as a result of failures of hydrotechnical structures have been reflected in cartographic materials, land relief, and sediments.
Grave of the Corded Ware culture from site 2 in Aleksandrowice, Kraków District
Authors: Peschel Kamila , Włodarczak Piotr
Published: March 2021

Graves from the Final Eneolithic period are very common in the loess uplands of western Lesser Poland (Małopolska). Their predominant form is a catacomb construction, related to the Kraków-Sandomierz group of the Corded Ware culture. A grave from Aleksandrowice, Kraków district, belongs to a smaller group of features known from the western border of this region. The grave goods are comprised of a stone battle-axe and a long blade knife, and the bones of the burial have not survived due to unfavourable soil conditions. The grave construction and the type of furnishing allow us to suppose that the grave was originally covered with a barrow. The faceted stone battle-axe with western stylistic connotations (Bohemia, Central Germany) is a unique find. It is the first find of this type in the western part of Lesser Poland. Based on the nature of the finds, the grave can be dated to around 2700–2500 BC, which means to the younger stage of the “barrow phase” of the Corded Ware culture.

In the 21st century, from bank to insurance, multinational companies to government offices have increased thousands of times their profitability, productivity, sustainability, and also market expansion through the successful uses of ICT. Today another aspect is the preparation of a high-quality financial report that relies entirely on the information. Quality information depends on several characteristics like completeness, accuracy, timeliness, consistency, validity, accessibility, and integrity of that information, etc. Having these characteristics in financial information is the prerequisite for good financial reporting. Usages of IT have a great role in producing quality information and financial reporting consequently. The use of IT in the banking sector is more sophisticated than in other sectors in Bangladesh. Therefore, the purpose of this research is to examine analytically the relationship between the use of Information Technology and the quality of financial reporting. Using primary data sourced a structured questionnaire was administered to selected banks in Bangladesh and data analysis was done through the General Regression Model by OLS method to examine the nature of the relationship that exists between the quality of financial reports and the Adoption of Information Technology. The result of the data analysis of the study showed that a positive correlation exists between IT and the quality of reports.

The patients’ rehabilitation who underwent radiotherapeutic treatment in the head and neck is still a challenge to dental implantation. The purpose of the current article is to discuss the installation of dental implants in patients who underwent radiotherapeutic treatment in the head and neck. The study of some literature was held considering revisions and original articles publications from 2002 to 2020. The research included the keywords: implants, osteoradionecrosis, neoplasms in oral cavity, hyperbaric oxygen therapy, laser therapy, ozone therapy e dental implants in irradiated bones. Databases: PubMed, SciELO e Bireme. The criteria for the article’s inclusion in the study were: an approach about the oral malignant neoplasm, the sequela treatment which may be formed and the implant installation in bones which underwent irradiation. The analysis was developed considering specific information from each article related to the language, publication year, research type and data results, in which the most of the cases have been positive to implants installation taking into consideration some factors. Taking into account the changes in the treatment concepts at first, then the advance of odontology in using the three-dimensional plans and surgical guides and, the evolution of the improvement in the titanium surface and the accomplishment of the minimum time of 12 months in the end of irradiation, it is possible to obtain a predictability in prosthetic treatment of patients undergoing radiotherapy in the head and neck region.

Kampilobakterioza je zoonoza koja se na ljude prenosi sa životinja i proizvoda životinjskog podrijetla, a prouzroči ju bakterija iz roda Campylobacter. Kampilobakteri su sveprisutni mikroorganizmi te ih možemo naći u svim vrstama mesa i proizvodima od mesa, sirovom mlijeku i mliječnim prerađevinama, rjeđe u jajima te u kontaminiranoj vodi. Kampilobakterioza je učestalija ljeti jer više temperature pogoduju rastu uzročnika ove bolesti. Tijekom ljetnog razdoblja (lipanj, srpanj, kolovoz) 2020. godine u tri klaonice sakupljeno je 60 uzoraka kože vratova tovnih pilića koji su pretraživani na bakterije iz roda Campylobacter. Od ukupnog broja pretraženih uzoraka, 28 (46,67 %) uzoraka bilo je iznad granične vrijednosti (1000 cfu/g) prema Uredbi (EU) 2017/1495, u 21,67 % određen je broj Campylobacter spp., ispod granične vrijednosti, a u 19 uzoraka je rezultat bio <100 cfu/g. Uzorci su obrađeni prema standardnom postupku određivanja broja kolonija Campylobacter spp. S obzirom na patogenost bakterija iz roda Campylobacter, od izuzetnog su značenja termička obrada hrane, dezinfekcija vode, sprječavanje križne kontaminacije te higijena prostora u kojem se hrana priprema s ciljem osiguranja zdravstvene ispravnosti hrane. Provođenje biosigurnosnih mjera i praćenje prevalencije kampilobaktera nužni su u klaoničkim objektima kako bi se smanjila učestalost pojave ove zoonoze.
