Topographic factor of water erosion – analysis of watershed morphometry and RUSLE LS factor in GIS environment
Authors: Nikolova Valentina , Mitova Milena , Dimitrov Emil
Published: October 2022

Soil erosion is the most serious soil degradation factor on the territory of Bulgaria. Nearly 66 % of its area have slopes in a range greater than 3°. The predominant hilly-mountainous relief and high slope degrees are prerequisites for development of water erosion. The properties of the topographic surface as a conditioning factor of erosion processes are evaluated in the current study on the example of the Dzhebelska River watershed (Southern Bulgaria). The following morphometric parameters are considered: basin relief, Melton index, slope and stream power index (SPI). Slope length and steepness factor (LS factor) is calculated using the slope degree and specific contributing area. The values vary between 0 and 43.36. The results of the analysis of the morphometric parameters indicate high erosion susceptibility in the upper and the middle part of the watershed but active erosion can be observed too in the low part of the watershed, where first order streams (Strahler’s method) flows directly to the river of fifth order. The current study is done in GIS environment on the base of 12 m digital elevation model.
Rhyolite-perlite transition zone in the acid volcanoes of the Eastern Rhodopes Paleogene volcanic area (SE Bulgaria)
Authors: Yanev Yotzo
Published: October 2022

In the siliceous volcanoes, the transition between rhyolites and perlite is carried out through a zone with the following morphology: i) rhyolite balls (spheruloids with spherulitic or felsitic texture) among the perlites; ii) alternation of subparallel perlite and rhyolite bands with felsitic texture; iii) a combination of the above two morphologies – rhyolite bands with spheruloids adhering to them; iv) alternation of finger-like wedge-shaped perlite and rhyolite wedges. The rhyolite spheruloids have Na composition (they are composed of tridymite and Na-K feldspar), while the perlites including them, as well as all rhyolites in the Eastern Rhodopes, are potassic. This chemistry, as well as many morphological features, show their immiscibility origin, which has been recently proven also experimentally (Kotel’nikov et al., 2016, 2019). Complex spheruloids are also observed, which consist of two types of spheruloids with different distribu¬tion of alkalis in them: small, in which Na>K and large spheruloids, which include small ones and in which potassium predominates. It is assumed that they are a product of a two-step immiscibility – in the first step large drops and matrix are formed, and in the second the large drops decompose into small drops (enriched with Na) and a new matrix (enriched with potassium), which is the building element of the large drops. The drops crystallize as spherulites, while the matrix solidifies as perlite. The spheruloids are products of nucleation and growth mechanism, i.e. they are formed in the fields between the binodal and spinodal curves. The other type of transition – the alternation of perlite and rhyolite bands is assumed to be formed by the spinodal decomposition, i.e. in the field limited by the spinodal curves.
Some Interesting Underground Cities and Peculiar Underground Structures of Kayseri (Turkey)
Authors: Yamaç Ali
Published: October 2022

Cappadocia, like many other parts of the world, is loaded with underground defense structures. The volcanic tuff, characteristic of the region, is easy to carve through and covers hundreds of square kilometers, thus providing favorable conditions for numerous underground defense structures. Consequently, almost every village in Cappadocia boasts at least one or more rock-cut structures. Although some are small and stand-alone structures, others constitute large and elaborate underground cities, including hundreds of meters-long tunnels and countless rooms. For more than seven years now, the OBRUK Cave Research Group has carried out the Underground Structures Inventory Project in Kayseri province. To date, 33 underground cities have been systematically explored and surveyed. This article begins with an introductory overview of the historical background and research of underground cities in Cappadocia and continues with an account of some of the most telling examples of these structures.

Authors: Nguyen Thanh Hung , Tran Ngoc Chau , Nguyen Thi Thuy , Ha Danh Duc
Published: October 2022

The herbicide of acetochlor has been widely applied to control weeds in agricultural sector, but it is responsible for numerous environmental hazards. In the current study, we investigated the effects of the herbicide on bacteria and microfungi communities in soil. The research findings revealed that acetochlor used at 1.24 mg/kg inhibited the growth of both bacteria and microfungi. Moreover, the degradation half-life values were greater at higher acetochlor concentrations in soil, from 12.3 ± 1.2 days at the concentration of 1.0× to 24.5 ± 2.5 days at 2.0×. The augmentation of P. fluorescens KT3 and amendment with peat in soil increased the degradation rates. Besides, the cultivation of peanut enhanced degradation of the compound, and stimulated the growth of bacteria and microfungi. This study showed a process to enhance the remediation of acetochlor in soil by augmentation of P. fluorescens KT3 and cultivation of peanut.

Published: October 2022

utachlor has been extensively applied to control weeds, increasing food production and reducing labor. In this study, butachlor degradation by Pseudomonas sp. But1 and Pseudomonas sp. But2 immobilized in polyurethane foam (PUF) was determined to compare with degradation by free cells. The degradation percentages of the pure compound by Pseudomonas sp. But1 and Pseudomonas sp. But2 were 100% and 96% within 24 hours at a concentration of 50 mg/L, respectively. Meanwhile, butachlor degradation in an Cantanil 550EC herbicide was completely after 30 hours. The determination of butachlor degradation by bacteria immobilized in PUF showed that degradation rates of immobilized Pseudomonas sp. But1 were more effective than those of Pseudomonas sp. But1. Even though degradation rates by immobilized bacteria were decreased after long-term storage of 90 days, Pseudomonas sp. But2 immobilized in PUF could be used to degrade butachlor in liquid media.

Engineering interfacial flows and instabilities in solidifying liquids
Authors: Brun Pierre-Thomas
Published: October 2022

This talk is concerned with interfacial fluid mechanics in the context of solidifying liquids. Due to favorable downscaling with length, capillary effects are dominant for submillimetric objects and play a key role is a number of engineering and natural processes where they dictate the shape of drops, thin films, and coatings. As such, interfacial effects have been widely researched, albeit primarily in Newtonian fluids or in fluids whose constitutive law remains constant over time. In particular, the subtle interplay between hydrodynamics, solidification and the solid structures formed when harnessing capillary effects remain poorly understood. We will attempt to fill this gap of knowledge and study the physics of viscous jets and sheets in solidifying liquids. We will discuss experiments conducted with a model system, an elastomeric solution, so as to elucidate the competing phenomena at play in the formation of patterns and structures arising from interfacial flows and their subsequent or concomitant solidification. We will revisit classic fluid mechanics models, e.g. lubrication, and adapt them to situations where the flow is arrested in finite time. First, we will discuss droplet forming instabilities and show that the patterns they form can be engineered via the use of templates. New phenomena, e.g. self-templating, will be explored too. Second, we will revisit classic coating, drainage and imbibition problems and demonstrate that these flows can be used for materials design, e.g. fabricate soft robots. In fact, curing converts the flows we study into elastic solids, introducing the concept of “building with flows”.
Development of a Combustion Module within the Nektar++ Framework
Authors: Forknall Aidan
Published: October 2022

In this project combustion modelling methods will be implemented into the framework of Nektar++, a spectral/hp element solver. The aim is to create a reactive multiphase flow solver capable of accurately modelling combustion flow regimes at low Mach numbers. To date, a pseudo-compressible multiphase flow solver has been developed based on the Incompressible Navier-Stokes code provided by Nektar++. The solver uses a low Mach variable density approach, able to simulate mixing between fuel and oxidizer phases. Validations have been performed with a canonical turbulent flow case and combustor relevant geometry such as cold flow of Sandia Piloted CH4/Air Flames. Simulations are LES, polynomial order 4, and have been completed using Lovelace and Sulis. For modelling of reactive flow, a 1D flamelet generated manifold (FGM) formulation dependant on mixture fraction, Z, is currently in development. Further FGM expansion is expected to include dependences on the variance of mixture fraction, Z’’, and if time permits, the progress variable, c, and its variance, c’’. The completed solver will be validated with canonical flame datasets and assessed against relatively ‘low’ and ‘high’ order reacting flow codes. Subsequently, the developed program will be applied to setups that are more representative of future combustors.
Fifty years of Biological Fluid Dynamics
Authors: Pedley Tim
Published: October 2022

I joined the Physiological Flow Studies Unit at Imperial College, London, as a PDRA, in 1968; it was founded in 1965-6 by its Director, Colin Caro, and Sir James Lighthill. I have been working in Biological Fluid Dynamics (BFD) ever since. This talk will describe some the following selection of the topics on which I have worked; I hope it will give a feel for how BFM has changed over the years and how an applied mathematician has been able to contribute:

1. Flow and pressure drop in branched tubes: prediction of inspiratory airway resistance.

2. Unsteady boundary layer theory: calibration of hot film anemometers in reversing (arterial) flow.

3. Flow in non-uniform and collapsible tubes and channels, including unsteady separation (experiment), vorticity waves and their possible influence on wall shear stress (WSS) in arteries (experiment and theory), self-excited oscillations in collapsible channels (theory and computation), with application to lungs, veins and arteries under a cuff (and maybe giraffes).

4. Individual and collective behaviour in suspensions of swimming micro-organisms: bioconvection, gyrotaxis, continuum modelling for dilute suspensions (algae) ; bioconvection for chemotactic bacteria; squirmer models (Volvox) and cell-cell interactions leading to computations for non-dilute suspensions; trajectory measurements for Heterosigma akashiwo near vertical and horizontal plane boundaries – some unexplained phenomena.
Flow transition of low Reynolds number flows past a plunging airfoil
Authors: Gao Ankang
Published: October 2022

The two-dimensional to three-dimensional transition of a flow past a plunging NACA 0012 airfoil at Reynolds numbers from Re=400 to 10 000 and an angle of attack of 15 degrees was investigated using global linear stability analysis and spanwise-homogeneous direct numerical simulation (DNS). Below a Strouhal number of 0.5, the transition Reynolds number is higher than the static airfoil which indicates the plunging motion stabilises the two-dimensional baseflow. For higher frequencies, an period-doubling mode first becomes unstable, which has a peak Floquet multiplier around a spanwise wavelength of 2c. This unstable mode also dominates in three-dimensional direct numerical simulations (DNS). Finally, a short-wave mode becomes unstable at St_c=0.95, which generates more small-scale vorticies in the DNS result.
Direct numerical simulation of the turbulence characteristics in a cylinder wake
Authors: Jiang Hongyi
Published: October 2022

The primary vortex street, turbulent kinetic energy and energy dissipation rate in the wake of a circular cylinder are examined at a Reynolds number of 1000 and up to 120 cylinder diameters downstream of the cylinder. The turbulence characteristics are quantified using direct numerical simulation (based on the framework of Nektar++), which provides a comprehensive dataset that is almost impossible to acquire from physical experiments. The energy dissipation rate is decomposed into the components due to the mean flow, the coherent primary vortices and the remainder. It is found that the remainder component, which develops only in a three-dimensional turbulent wake, accounts for the majority of the total dissipation rate for almost the entire wake. The turbulence dissipation in the wake is largely locally homogeneous, but not locally isotropic or axisymmetric, even after the annihilation of the primary vortex street. The spatial distribution of the turbulence characteristics relative to the spatial distribution of the primary and streamwise vortices is also examined.
Unsteadiness of Shock Wave / Turbulent Boundary Layer Interactions
Authors: Clemens Noel
Published: October 2022

Shock wave / boundary layer interactions are an important feature of high-speed flow that occur in supersonic and hypersonic aircraft inlets, aircraft control surfaces, missile base flows, nozzles, and rotating machinery. These interactions are often associated with severe boundary layer separation, which is highly unsteady, and exhibits high fluctuating pressure and heat loads. The unsteady motions are characterized by a wide range of frequencies, including low-frequency motions that are about two orders of magnitude lower than the integral-scale fluctuations in the upstream boundary layer. The low-frequency motions are particularly problematic for aircraft structures as they can excite high-amplitude vibration of thin panels, which can lead to fatigue and failure. In this seminar, we will discuss experimental research on various types of shock wave / boundary layer interactions that we have conducted over the past 20 years. The discussion will focus on the use of high-speed PIV and pressure sensitive paint to investigate the physical mechanisms that drive the separated flow unsteadiness in 2D and 3D interactions.

This study aims to characterize the agricultural production systems under urban and peri-urban agriculture (UPA) in the Curuçambá neighborhood; identify the main techniques and technologies adopted, cultivations and creations conducted, and the activity relationship within the Metropolitan Region of Belém (RMB); and estimate the production contribution to family consumption complementarily and exploratorily. Data were obtained through interviews conducted among 63 residents in the neighborhood (representing 52.50% of the universe) by monitoring the food consumption of six producers’ families for two weeks and georeferencing images from Google Satellite. Farmers were mainly from the northeast of Pará (57.14%) and other Brazilian states such as Maranhão (9.52%), Ceará (9.52%), and Paraíba (1.59%). Clearly, urban agriculture in the region was established during the migration of rural areas to Amazonian cities. Generally, most farmers had reached elementary school II (69.84%) and had an average monthly income of one to two minimum wages (50.79%). Agricultural production was promoted by approximately 111 residences in the neighborhood and was based on horticulture and small livestock keeping. Additionally, the items analyzed were allegedly produced in six production systems: common beds (71.43%), suspended beds (12.70%), fruticulture (6.35%), agroforestry yards (3.17%), hydroponics (4.76%), and aquaponics (1.59%), and were directed to supply the RMB markets. On average, 30.89% of farmers’ income covered family consumption; we estimated the opportunity cost of consumption for the five main products cultivated in the neighborhood (jambu, lettuce, coriander, chicory, and cariru) as R$ 79.88 monthly, accounting for 8.37% of the current minimum wage at that time.

The way towards a European patent judiciary is best characterised by the title of a Beatles song: it has been “a long and winding road”. But after many proposals, initiatives and setbacks the Unified Patent Court now finally seems to become reality. The tricky issue of whether the UK could still participate even after Brexit1 has been solved – in a very unfortunate way, but it has been solved. The constitutional challenge in Germany has made a new implementation in the German Parliament necessary,2 but the new implementing act reached the necessary two-third majority, and the German Federal Constitutional Court has recently refused to accept a constitutional complaint against the new implementation.3 The UPC Agreement (hereinafter UPCA) has now reached the stage of provisional application. Germany is acting as a gatekeeper and will deposit its ratification once the preparations have been finalised.4

Criza pandemică ne-a demonstrat ironic și paradoxal forța nemaipomenită a schimbării sau necesitatea de a ne schimba prin degradarea relațiilor cu autoritățile și prin fenomenul work from home sau school from home. Schimbarea are sens, că este vorba fie despre un fenomen generat în mod natural, fie despre o consecință a unei acțiuni omenești. Cuprins între o realitate obiectivă și una subiectivă, sistemul de învățământ militar are puterea de a produce mutații calitative printr-o nouă versiune, cea intersubiectivă, în care accentul cade pe importanța valorilor și credințelor care, dincolo de resursele fizice, au constituit de-a lungul istoriei, mai ales prin războaiele purtate, cea mai importantă resursă prin care liderul obținea, prin strategia asumată, victoria.

Published: October 2022

Procesul de dezindustrializare a României, aplicat metodic și insistent după anii `90, pare a nu se integra parcursului firesc spre industria 4.0, ci mai degrabă pare a fi un proces sistematic de distrugere planificată și de radiere a industriei postdecembriste, pe sistemul unui nou plan Valev, conceput în laboratoarele secrete ale artizanilor noii configurații mondiale. Insistența cu care s-a procedat la demolarea sistematică și planificată a majorității capacităților și platformelor industriale mari trădează interese obscure, care nu mai pot fi plasate sub umbrela catalogării lor ca învechite sau neperformante, ci mai mult ca incomode pentru piețele externe și capitalurile străine. Pentru a înțelege mai bine mecanismele care au acționat în vederea resetării României și readucerii acesteia la statutul de colonie semiagrară, exportatoare de materii prime, de resurse naturale și de forță de muncă ieftină, concretizată prin distrugerea industriei grele, petrochimice, alimentare și constructoare de mașini, va trebui să pătrundem în esența cadrului de manifestare a proceselor care susțin globalismul ca ideologie și globalizarea ca politică suprastatală și neocolonialistă a marilor centre de putere internaționale
Challenges facing blood transfusion services at a regional blood transfusion center in Western Kenya
Authors: BM Kavulavu , BN Bushuru , NN Muendo , WO Kumotia , JC Kipkulei , TC Lotodo , JK Kirinyet , F Tum , A Obala
Published: October 2022

Aims: The demand for blood and blood products in sub-Saharan Africa is occasioned by tropical infectious diseases and obstetric complications that cause anemia. We therefore need a well-organized blood transfusion service with sufficient resources to process blood and blood products, especially in the Western Kenya, where co-infections of tropical diseases are rampant. This study was aimed at determining the blood deficiency and challenges experienced by Eldoret Regional Blood Transfusion Center (ERBTC).

Methods: A cross-sectional descriptive design was used to conduct the study. All the ERBTC staffs, donor records, and blood requisition and dispatch registers were studied. Self-administered questionnaires and data collection abstraction forms were used to collect data. The extracted data from ERBTC registers included those on demand and supply mismatches and blood discards. The obtained data were entered into Microsoft Excel and analyzed using descriptive statistics.

Results: A total of 16 staffs, 230 donor records, and 9612 units of requested blood were reviewed. The ERBTC reported many challenges ranging from understaffing, limited funding, insufficient equipment, and irregular reagents and other laboratory supplies. During the study period, the blood bank only managed to supply 4740 units of blood against a demand of 9612 units, thus occasioning a 50.7% deficit. A discard rate of 7.8% after the screening was also reported due to insufficient volumes after collection and transfusion transmissible infections. However, there were no wastages during the study period.

Conclusion: The main challenges experienced by ERBTC were understaffing, insufficient funding, limited equipment, frequent reagent outages, and discards of unsuitable blood, resulting in very high deficits. We recommend hiring staff, increased funding, acquiring modern equipment and reagents, and recruiting known regular blood donors to alleviate frequent shortage.
Results of the study of electroexcitability of the skin in the area of innervation of the lower alveolar nerve

Published: October 2022

In patients with mandibular fractures, 87.6% of cases showed varying severity damage to the lower alveolar nerve (LAN). So, in most cases, when the displacement of fragments is less than 0.5 cm, a mild degree was noted, when the displacement is from 0.5-1.0 cm - an average degree, and more than 1.0 cm-a severe degree of damage to the LAN. In 3.7% of cases, violations of deep sensitivity were detected. It was revealed that the highest rates of electrical excitability of the skin were noted in 2-the 2nd and 3-3rd zones. So, at admission, the average values in patients with mild severity of damage were noted at the level of 56.5±1.5 mkA, with an average degree - of 115.8±3.1 mkA, with severe-163.8±4.5 mkA. It is noted that the higher the indicators, the more pronounced the violation of sensitivity. The values of indicators in the main group by day 32-40 were 1.6 times less than in the control group.

Las micro, pequeñas y medianas empresas son una parte muy importante para cualquier economía en el mundo. En México representan más del 90 por ciento de las empresas existentes. Un reto al que se enfrentan estas organizaciones es la adquisición de conocimientos y la habilidad para absorberlos. Estas empresas pueden traer conocimientos del exterior para aprovecharlos y usarlos dentro de sus procesos internos, pero cómo adquieren conocimientos y cómo los llegan a aprovechar para el funcionamiento de sus organizaciones. Dentro de esta investigación se realizó un estudio de caso en tres empresas, donde se identificaron rutinas y actividades dentro de las cuatro dimensiones de la capacidad de absorción de conocimiento: Adquisición, asimilación, transformación y explotación. Como resultado se obtuvo el proceso de absorción de conocimiento de las organizaciones, es decir, un conjunto de rutinas y actividades que estas empresas llevan a cabo para absorber conocimiento.

The need to obtain consistently high yields of agricultural plants in the Siberian Federal District is sufficiently high. Therefore, this work aimed to study the influence of protective structures on the growth, development, and productivity of tomatoes in the Novosibirsk region. The data obtained allow concluding that the use of protective structures protects plants from recurrent frosts, gusts of northern winds, and a sharp drop in temperature. Plants grown in standard protective structures, in the first periods after planting at a permanent place of growth, were subjected to stressful situations, which led to a decrease in the immunity of the plant and, as a result, damage by fungi and bacteria.

This study aims to understand how ERP users see their role and interpersonal relationships to avoid hidden costs linked to its misuse. In order to understand the actors that are part of the functional network as users of ERP system, the study was carried out in a case study exploratory qualitative approach considering both the lack of similar previous studies in the literature and the understanding of the company in its own context. The process of data collection considered categories regarding organizational culture and hidden costs. The study used primary and secondary evidence for data triangulation. After organization and transcription of the collected material, content analysis was applied as data analysis technique on them. The investigated company proved to be positive for all the cultural characteristics analyzed, although it still presents dysfunctions in its activities. It was concluded that excluding situations with perfect system and actors, all organizations are subject to hidden costs. The observation of these can operationally, competitively and financially boost the organization, it is up to the manager to choose whether or not to pay attention to the “iceberg” in his direction. The research presents practical contributions to companies of the civil construction and also provides academic contribution by addressing the issue of costs information systems through a theoretical perspective from organizational culture.

Authors: Tyng Teh Soo , Aman Aini
Published: October 2022

Coopetition involves multidisciplinary actors in a competition and cooperation phenomenon simultaneously. There is a large research gap on how a coopetition process is established and managed in a business ecosystem. Through the in-depth analysis of a single printing business ecosystem in Malaysia, this paper finds coopetition is common as the way of doing business among the micro, small and medium sized firms in one industrial park growing into a popular printing ecosystem in Selangor state of Malaysia. This paper identifies the sources of coopetition, challenges faced by different firms in the same industry and the mechanism of these firms surviving in this business ecosystem. Through a case study, our findings showed that informal cooperation more likely than a structured coopetition to achieve short-term success yet a long term resilience for small medium enterprises. The possible tension in coopetition is reduced when trust and friendliness is available to maintain the business ecosystem position. The interchangeable supplier-customer relationships facilities value co-creation through exchange of resources and capabilities in the geographic, technological and market overlap business ecosystem. The paper suggests the coopetition strategy is the base strategy to build competitiveness of individual firm located in a business ecosystem.

Lots of people have heard the term growth mindset. What is it and why is it so important? Growth mindset is the belief that intelligence and other abilities are malleable, and that we can improve them—through effort, seeking help, and trying new strategies. That’s distinguished from a fixed mindset, believing that you either have it or you don’t, that you’re a math person or an artsy person—or you’re not.

DNA analyses and DNA-based diagnoses are going forwardly in the commercial deals with shrimp (Penaeus monodon) as well as in the basic research. In this regard extraction of DNA is obvious. However, numerous protocols are available DNA extraction from animal tissue. Therefore, which technique is suitable one for shrimp tissue is indispensable to justify. In the current study, a protocol was optimized for extraction of DNA from shrimp collected from Batiaghata, Khulna. Muscle Tissue (MT) and Hepatopancreas Tissue (HT) were distinctly sampled on15th March, 2007 from only one fresh individual for each of six protocols applied. Guanidium isothiocyanate treatment involving two groups of commercial preparation (DNAzol from invitrogen® and DNA Extraction Buffer (DEB) from Genei®) with or without RNAse, as well as Proteinase K isolation technique and sodium dodecyle sulfate (SDS) isolation technique were applied to extract DNA. The quantity (µgml-1) and quality were determined by UV spectrophotometry at A260nm and A260/280 respectively. The current study provided that the quantity of DNA obtained with almost every protocol was higher when the hepatopancreas tissue was used. Among six protocols, DEB with RNAse (102.5 µgml-1 for MT, 302.5 µgml-1 for HT) resulted the highest concentration of DNA with acceptable level of purity (A260/280 1.86 for MT and 1.70 for HT).
