Geomorphological engineering studies of anthropogenic variability of relief in the marine coastal zone

With the development of the coastal zone and the development of the urbanization process, coastal engineering poses a serious threat to local ecosystems. Poorly designed coastal engineering will have irreversible consequences for local ecosystems, such as loss of biodiversity, loss of connectivity and overall degradation of ecosystems. Therefore, it is imperative to improve the concept of ecosystem design of coastal infrastructure. One of the most important problems of marine engineering geomorphology is the drift of approach channels and changes in the coastal relief. These phenomena are a manifestation of a single process of sediment movement along the coast. The main deformations of the relief, as a rule, are determined by the features of the transverse structure of the alongshore sediment flow. This study discussed the methodology for calculating the movement of sediments, the transformation of the relief of the coastal zone. Regional examples show in general terms the assessment of the drift rate of different channels and different sections of individual channels. The problem of drift and artificial deepening of approach channels of ports is highlighted on the example of the coastal zones of the Baltic Sea. In general, these studies can contribute to improving the development of ecosystem coastal engineering.
A comparison of laboratory and pilot plant experiments on the combination of flocculation/ultrafiltration for direct potable water treatment of river water

A direct treatment of river waters with ultrafiltration is not yet realised in larger scales due to considerable fouling and scaling effects caused by water contaminants on the membranes surface under those circumstances. Therefore, the deposits on the membrane cannot be eliminated extensively by conventional backwashing. An extensive detachment of the formed layers while backwashing is desired to achieve cost advantages when using the process combination flocculation/ultrafiltration for the direct treatment of surface waters. Hence, pilot and laboratory plant experiments were carried out while dosing different coagulants at different pH-values with different concentrations of the coagulant to investigate their influence on the build-up of the coating layers. The experiments described here were focused on the following questions. Firstly, how do coagulation and flocculation conditions influence the performance of the treatment combination flocculation/ultrafiltration and which coagulant is best? Secondly, does a good operational performance of the combination flocculation/ultrafiltration at laboratory scale coincide with good operational performances at the pilot plant or does the presence of dissolved organic carbon (DOC) in the raw water decrease the performance significantly? Thirdly, does a good operational performance coincide with an extensive reduction of DOC, or humic substances, respectively?
The Impact of Teaching Methods and Materials on the Teaching of Citizenship Education in Cameroon: A Study of Case Schools in Buea Municipality

The purpose of this study was to investigate the impact of methods and materials on the teaching of Citizenship Education in Secondary Schools in the Buea Municipality. Two research questions were formulated to guide the study: To find out how teaching methods influence the teaching of citizenship, and how the use of instructional materials influence the teaching of citizenship in secondary schools in Buea Municipality. The study adopted a qualitative approach, using the multiple case study design to carry out the investigation with the help of an interview and an observation schedule. It involved 6 citizenship education teachers from 3 sampled case schools; Summerset Bilingual High School Molyko, Government Bilingual Grammar School Molyko, and Baptist high school Great Soppo. The purposive sampling procedure was used to select the participating schools and teachers of the study. Two teachers were interviewed, and one teacher observed in each school, to find out whether the methods and materials used were in line with those proposed by the syllabuses. The data from interview and observation were transcribed and coded thematically. The findings showed that citizenship education teachers use mostly teacher-centered methods in teaching, in contradiction to the learner-centered methods prescribed in the syllabus. Teachers do not have the subject syllabuses and so rely on textbooks for their teaching of the subject.
Why do some social enterprises flourish in Vietnam? A comparison of human and ecosystem partnerships

Purpose Social enterprises can be found across Vietnam. However, little is known about how these organizations contribute to the country’s broader efforts to meet the United Nations Sustainable Development Goals (SDGs). This paper aims to explore whether and to what extent differences in social impacts by social enterprises may be explained by the psychological characteristics of social entrepreneurs and cross-sector “ecosystem” partnerships in training, networking, consultation and funding. Design/methodology/approach A survey of N ≈ 352 Vietnamese social entrepreneurs explored relationships between individual entrepreneurial orientation (EO), social identity, self-construal and personality, with elements of ecosystem partnerships (access to training, networking, consultation and funding) and social impacts over the previous three years (growth/jobs created and people helped, termed efficiency and generosity, respectively). Findings Ecosystem partnerships factored into frequency and quality of partnerships. Frequency predicted social enterprise efficiency (p < 0.05) and quality predicted generosity (p < 0.01). Frequency of partnerships further moderated (boosted) significant links between EO (risk innovation, p < 0.05) and efficiency; and between social identity (communitarianism, p < 0.01) to efficiency; plus, quality of partnerships moderated a link between EO (risk innovation) and efficiency (p < 0.05). Practical implications Ecosystem partnerships may foster social enterprise development through at least two pathways (equifinality), i.e. frequency and quality. The former is linked to efficiency and the latter to generosity, signaling interrelates but distinguishable outcomes. Direct links between EO and communitarian social identity leading to social enterprise development were additionally boosted (p < 0.05) by the frequency and quality of partnerships. Thus, ecosystem partnerships brought about both direct and indirect benefits to social enterprises in Vietnam. Social implications Social impacts of efficiency and generosity support both decent work (SDG-8) and poverty eradication (SDG-1), through ecosystem partnerships in development (SDG-17). Originality/value To the best of the authors’ knowledge, this is the first empirical study to show that social enterprises in Vietnam may enhance social impacts through a combination of effects from social entrepreneurs and ecosystem partnerships. Current models of social enterprises in low-income countries like Vietnam can be expanded to include ecosystem partnerships and social outcomes relating to SDGs 1 and 8, and especially the multiple path benefits that ecosystem partnerships (under SDG-17) bring to social enterprise development.
A current perspective on antibacterial and antibiofilm properties of waru (Hibiscus tiliaceus L.)

During the long course of evolution, disease-causing pathogenic bacteria have developed a variety of virulence mechanisms that help them establish and maintain infections. Among these mechanisms are the production of biofilm protecting the bacteria from undesirable environmental conditions and contributing to the development of new multi-drug-resistance bacterial strains. Hence, biofilm has become an attracted target for the development of a novel strategy in fighting against biofilm-forming pathogens. There has been much work to look for novel antibacterial and antibiofilm agents, including the use of plant-derived materials. Hibiscus tiliaceus is one of the widely known medicinal plant with antibacterial and antibiofilm properties. This review focuses on antibacterial and antibiofilm properties of H. tiliaceus as well as the major phytochemical constituents that might contribute to these activities.
Comparative content of biologically active substances in wood species of the north of the forest steppe on the example of Lipetsk region

The wood of 22 of the most common low resinous tree species were studied. The number of polyphenols in the wood of the studied species ranges from 23.6 to 1433.1 mg% (0.02-1.43%). The maximum number is noted in the wood of thorny blackthorn. As the wood of fruit species ages (over 3 years old), the content of polyphenols decreases. The content of organic acids in wood of tree species varied in the range of 0.21-1.08%. The leader in terms of their content was the common rowan tree. The amount of tannins and dyes in wood species ranged from 1.45 to 26.5% and was maximum in the tissues of thorny blackthorn. The tannin level in the tissues of the tree species was 0.83-20.8%. The highest tannin content was in the wood of the rowan tree. With the natural drying of wood of 20 species within 8 months in a ventilated room at an air temperature of 25° C, the moisture content of the wood decreases 1.4-3.83 times and is set at the level of hygroscopicity (11.47-35.6%). In the process of slow drying of wood species, organic acids are not destroyed in them, but are concentrated. The least hygroscopic is the wood of the walnut and pedunculate oak, the most hygroscopic is the wood of the heart-shaped linden.

Treatment Following Erythema Multiforme in the Oral Mucosa After qHPV Vaccine with Low-Level Laser Therapy: Case Report

Erythema multiforme (EM) is a mucocutaneous condition of uncertain etiology, although the hypersensitivity reaction to a wide variety of agents may be related to the onset of the lesions. In about half of the affected patients it is possible to identify a previous infection. This article aims to report a case of EM in the oralmucosa after qHPV vaccine (Gardasil), to highlight the diagnostic process and the proposed treatment. Female patient, 16 years old, after 10 days of receiving the first dose of the qHPV vaccine. On physical examination, she presented multiple ulcers and hemorrhagic crusts to the touch, based on the clinical picture and the history of the disease, a diagnostic hypothesis was EM. Low-level laser therapy (LLLT) was chosen as an alternative treatment, since the exercises applied were not successful. The patient was followed up, reported decreased pain and burn and, after one year of treatment, there was no recurrence of the lesions. Laser treatment showed an effective treatment alternative, in addition to the low cost and ease of application.
Plasma-Activated Water Modulates Root Hair Cell Density via Root Developmental Genes in Arabidopsis thaliana L.

Low-temperature atmospheric pressure plasma technology has been used in agriculture and plant science by direct and indirect treatment of bio-samples. However, the cellular and molecular mechanisms affected by plasma-activated water (PAW) are largely unexplored. In this study, PAW generated from a surface dielectric barrier discharge (SDBD) device was used for plant development. Physicochemical analysis was performed to confirm the PAW properties that correlated with the plasma treatment time. Arabidopsis thaliana L. was utilized to study the effect of the PAW treatment in the early developmental stage. The plasma-activated water samples are denoted as PAW5 time in minutes (min), PAW7 min, PAW12 min, PAW19 min and PAW40 min with the plasma treatment time. Seedlings grown in the PAW5, PAW7 and PAW12 had increased root lengths while the root lengths were decreased in the PAW19 and PAW40. In the cellular level observation, the PAW treatment specifically increased the root hair numbers per unit of the root but suppressed the root hair length in the PAW, indicating that PAW mainly modulates the root hair cell density in the root. Furthermore, we found that the root hair density and length at PAW5 in maximal observed conditions were positively regulated by root developmental-related genes including COBRA-LIKE9 (COBL9), XYLOGLUCAN ENDOTRANSGLUCOSYLASE/HYDROLASE9 (XTH9), XTH17, AUXIN1 (AUX1) and LIKE-AUXIN (LAX3).
Isolation of Heterocysts from Anabaena sp. PCC 7120

[Abstract] During combined nitrogen step-down, filaments of cyanobacterium Anabaena sp. PCC 7120 differentiate about 5-10% of vegetative photosynthetic cells into heterocysts, the specialized cells for N2 fixation (Walk, 1996). Heterocysts have a thick cell wall reducing permeation of O2 and consist of two additional layers composed of glycolipids and polysaccharides. The difference in structure and composition of the cell wall between heterocysts and vegetative cells allows separation and isolation of heterocyst. Heterocysts isolated by this protocol can be subjected to protein analysis and activity measurements, which do not require strict anaerobic conditions.
On the fluctuation induced mass enhancement

The effective mass induced by the background fluctuation on particles is considered. The analytical results show that the effective mass depends only on the properties of fluctuation, and takes non-zero value when and only when fluctuation mean value is non-zero. The possible applications of the obtained results to complex systems such as biology and ecology where environmental factors lead to the changes of the information exchange ranges from long to short one are discussed, i.e. the possibility of using physical modeling techniques to investigate macroscopic behaviors of some complex systems under consideration.
Deep‐features with Bayesian optimized classifiers for the breast cancer diagnosis

To improve the state‐of‐the‐art works in breast cancer diagnosis, this paper proposes ensemble‐based deep‐transfer learning with classifiers namely optimizable K‐nearest neighbors, optimizable naïve Bayes, optimizable ensemble, and optimizable support vector machine algorithms for the auto‐feature extraction, detection, and severity classification of input mammograms. The hyperparameters of these classification algorithms are optimized by using the Bayesian optimization technique. The extracted robust features are normalized and then classified using the Bayesian optimized classifiers. Thus, the work throws a light of research on detecting whether the input mammogram is normal or abnormal. Afterward, it further focuses on the severity classification of abnormalities that is, benign or malignant. The aforesaid algorithms are trained and tested for the three‐class classification problem, thus achieving a maximum performance using the Bayesian optimized SVM algorithm applied with ResNet18 deep features providing classification accuracy of 99.689% for MIAS and 98.883% for INbreast dataset.
Freedom and Desire: A Quest for Spiritual Journey in James Joyce’s Novel Ulysses/A Portrait of the Artist as a Young Man

This study, Freedom, and Desire: A quest for a spiritual journey in the novel by James Joyce, describes the journey of the main character of the story from his adolescence to the best way of conceptualizing the dynamic, multilateral relationship between individual experience and sociocultural scope, since it recognizes the causal significance of culture but also recognizes individual choice and changes. The researcher examines the true desire which enables him to embrace his creative spirits “the actual experiences” which also symbolize freedom. This claim is formed by contemplating how many historical shifts in the socio-cultural context, i.e. the increase in freedom of choice, the shift in interpersonal patterns, the loss of traditional values, the loss of religious understanding, and the increasing conflict between the desire for individuality and the complexity of achieving it, have led to changes in the essence of true intentions and modern personhood. For this research, a qualitative method is adopted in the framework of Locke on Freedom (2015). It also points out and aims at the need to establish a new perspective on the provision of spiritual treatment in the field of freedom and desire, which focuses on improving the particular spiritual journey of the person, rather than simply reassuring spiritual distress. A man should not have to restrict himself to limited ideas, for this one has to go beyond limitation to change his mind which is the ultimate reality of advancement in life.
Monitoring superficial water content for systemic burn resuscitation with spatial frequency domain imaging

Adequate resuscitation is critical for burn wound patients where the affected total body surface area (TBSA) exceeds 20%, as fluid loss leads to organ failure, shock, and patient mortality. Protocols have been developed to combat fluid loss, however excess fluids can also lead to compartment syndromes. Here, we used spatial frequency domain imaging (SFDI), a non-contact wide field imaging technique to measure in-vivo water changes in a 40 % TBSA porcine burn model. In this pilot study one pig received intravenous fluids according to the Parkland formula on top of enteral fluid resuscitation, while a second pig received no fluids during the experiment. Unburned regions of skin were imaged with SFDI from 3 to 22 hours post-burn. This imaging technique uses structured illumination, projected at multiple spatial frequencies and wavelengths, to measure tissue reflectance, which is used to obtain the reduced scattering and absorption coefficients. Water fraction is based upon absorption in the near-infrared spectrum at 971 nm, where water has a high extinction coefficient. SFDI measurements of superficial tissue hydration showed increased water fraction for the pig that received fluid resuscitation (+17%), and a decrease for the pig that received no fluids (-5%). Analysis showed decreased scattering measured in the pig that received fluids (+13%), suggesting increased interstitial water pressure. These preliminary results are consistent with systemic hydration, as estimated based on CT-measured subcutaneous fat thickness. SFDI may, therefore offer the possibility of non-invasively monitoring fluid resuscitation of large TBSA patients.
The Baltimore Urban food Distribution (BUD) App: Study Protocol for A Food Systems Intervention

Background: Low-income urban communities in the United States commonly lack ready access to healthy foods. This is due in part to a food distribution system that favors the provision of high-fat, high-sugar, high-sodium processed foods to small retail food stores, and impedes their healthier alternatives, such as fresh produce. Methods: The Baltimore Urban food Distribution (BUD) study is a multi-level, multi-component systems intervention that aims to improve healthy food access in low income neighborhoods of Baltimore, Maryland. The primary intervention is the BUD application (app), which uses the power of collective purchasing and delivery to affordably move foods from local producers and wholesalers to the city’s many corner stores. We will implement the app in a sample of 38 corner stores, randomized to intervention and comparison. Extensive evaluation will be conducted at each level of the intervention to assess effectiveness via process and impact measures on suppliers, corner stores, and consumers. Discussion: BUD represents one of the first attempts to implement an intervention that engages multiple levels of a local food system. The design of the intervention and the evaluation plan of the BUD project are documented here.Trial registration #: #### (register since not yet recruiting)
French grapevines classed in phenotypical ecogeogroups essay

Two specialists, NEGRUL (1946) et LEVADOUX (1948) proposed for Europe vine-plants cultivated a classification in natural groups issued from ecogeographical areas relatively closed in their situations and evolutions. These ampelographs are complementary in their propositions, Russian for Eastern Europe and French for Western forms. Middle-East is the probable origin of mediterranean viticulture with its vine-varieties then the local wild forms in more septentrional vineyard extensions. After sortotypes or ecogeogroups definitions, anterior structural propositions of French vine-varieties in eco-geographical groups are developped by individual integration forms in taxonomic and morphologic unities. The present propositions are not immovable nor definitive but as such they may be useful in recent genetic advancements. They can confirm or not some new biochemical diagnosis.
Institutional Quality and Trade Flow: Empirical Evidence from Malaysia and Other OIC Member Countries in Africa

This article examines the impact of institutional quality on bilateral trade flow between Malaysia and selected 25 African Organisation of Islamic Cooperation (OIC) member countries. Four institutional qualities were selected from World Governance Indicators with other trade predictors from the period from 1985 to 2016. Using gravity model of trade and Poisson pseudo-maximum likelihood estimation method (PPML) technique, the results confirm that government effectiveness, regulatory quality and political stability have an adverse effect on bilateral trade flow among the OIC countries in Africa. On the other hand, these institutional quality variables were considered as a strength for Malaysian economic growth. Therefore, better institutional quality reforms are needed among OIC member countries in Africa in order to accelerate trade, economic growth and development in their region.
Lipine grain and amido-concentrative additives in young cattle feeding

The development of intensive forms of animal husbandry and the consistent improvement of their efficiency require solving both technical problems and issues of feeding and using full-fledged and cost-effective feed for all types of bred animals. This article presents data on the use of feed additives containing natural antioxidants in the aspect of influence on the quality indicators of the resulting meat. The assessment was carried out after a control slaughter at the age of 120 days in the amount of 3 heads from each group. The results of physical and chemical tests of rabbit meat of experimental groups are presented, and the positive effect of natural additives “Vitazar” and “Ecostimul” on the quality indicators of raw meat is determined.
High-resolution phased array signal processing via DFT beamspace TLS-ESPRIT with structure weighting

A new algorithm, DFT beamspace TLS-ESPRIT with structure weighting is presented. The proposed algorithm provides closed-form estimates of the directions-of-arrival (DOAs) of signals impinging on a uniform linear array (ULA). DFT beamspace TLS-ESPRIT with structure weighting outperforms DFT beamspace TLS-ESPRIT in terms of estimation accuracy, mainly at small and mean values of SNR, and conserves the low computational complexity of the latter algorithm. Improvement of performance is conditioned by exploiting structure (row) weighting method. Distinctions in realization of structure weighting in beamspace as compared to element space are noted. The performance of the proposed algorithm is evaluated by computer simulation, verifying its statistical efficiency.
