Air pollution affects our day to day activities and quality of life. It poses a threat to the ecosystem and the quality of life on the planet. The dire need to monitor air quality is very glaring, owing to increased industrial activities over the past years. People need to know the extent to which their activities affect air quality. This project proposes an air pollution monitoring system. The system was developed using the Arduino microcontroller. The air pollution monitoring system was designed to monitor and analyze air quality in real-time and log data to a remote server, keeping the data updated over the internet. Air quality measurements were taken based on the Parts per Million (PPM) metrics and analyzed using Microsoft Excel. The air quality measurements taken by the designed system was accurate. The result was displayed on the designed hardware’s display interface and could be accessed via the cloud on any smart mobile device.
Urban rent at risk: the point of viewof private investors [Rendita urbanaa rischio: la prospettiva degli investitori privati]
Authors: Oppio Alessandra , Torrieri Francesca , Dell’Oca Emanuele
Published: May 2021

Urban transformation and regeneration interventions are complex processes in which a multitude of actors act in order to generate an overall value higher than the investment and proportional to the risks, related to each phase of real estate development process. The trade-off between risk and return is one of the essential element in investment decisions, even more in the context of urban transformations projects characterized by long-term time horizons, hence the difficulty for investors to predict the future. In this context, the paper proposes a reflection on the relationship between return and risk in urban transformation and regeneration interventions, focusing on the private investor’s perspective. A first questionnaire was proposed to a selected panel of experts, as pre-test, in order to highlight how the different actors involved in development processes perceive risk and how their adversity varies due to their role and the development phase. The first results of the pre-test phase have pointed out interesting aspects that deserve an in depth investigation through a survey extended to a larger sample, such as the importance of the involvement of private operators and the use of multidimensional and multi-stakeholder models to support risk management.

How is Baseflow Index (BFI) impacted by water resource management practices?
Authors: Bloomfield John P. , Gong Mengyi , Marchant Benjamin P. , Coxon Gemma , Addor Nans
Published: May 2021

Abstract. Water resource management (WRM) practices, such as abstractions and discharges, may impact baseflow. Here the CAMELS-GB large-sample hydrology dataset is used to assess the impacts of such practices on baseflow index (BFI) using statistical models of 429 catchments from Great Britain. Two complementary modelling schemes, multiple linear regression (LR) and machine learning (random forests, RF), are used to investigate the relationship between BFI and two sets of covariates (natural covariates only and a combined set of natural and WRM covariates). The LR and RF models show good agreement between explanatory covariates. In all models, the extent of fractured aquifers, clay soils, non-aquifers, and crop cover in catchments, catchment topography and aridity are significant or important natural covariates in explaining BFI. When WRM terms are included, groundwater abstraction is significant or the most important WRM covariate in both modelling schemes and discharge to rivers is also identified as significant or influential, although natural covariates still provide the main explanatory power of the models. Surface water abstraction is a significant covariate in the LR model but of only minor importance in the RF model. Reservoir storage covariates are not significant or are unimportant in both the LR and RF models for this large-sample analysis. Inclusion of WRM terms improves the performance of some models in specific catchments. The LR models of high BFI catchments with relatively high levels of groundwater abstraction show the greatest improvements, and there is some evidence of improvement in LR models of catchments with moderate to high discharges. However, there is no evidence that the inclusion of the WRM covariates improves the performance of LR models for catchments with high surface water abstraction or that they improve the performance of the RF models. These observations are used to formulate a conceptual framework for baseflow generation that incorporates WRM practices. It is recommended that information on WRM, particularly groundwater abstraction, should be included where possible in future large-sample hydrological data sets and in the analysis and prediction of BFI and other measures of baseflow.
Creep and fracture of warm columnar freshwater ice

Published: May 2021

Abstract. This work addresses the time-dependent response of 3 m×6 m floating edge-cracked rectangular plates of columnar freshwater S2 ice by conducting load control (LC) mode I fracture tests in the Aalto Ice Tank of Aalto University. The thickness of the ice plates was about 0.4 m and the temperature at the top surface about −0.3 ∘C. The loading was applied in the direction normal to the columnar grains and consisted of creep/cyclic-recovery sequences followed by a monotonic ramp to fracture. The LC test results were compared with previous monotonically loaded displacement control (DC) experiments of the same ice, and the effect of creep and cyclic sequences on the fracture properties were discussed. To characterize the nonlinear displacement–load relation, Schapery's constitutive model of nonlinear thermodynamics was applied to analyze the experimental data. A numerical optimization procedure using Nelder–Mead's (N-M) method was implemented to evaluate the model functions by matching the displacement record generated by the model and measured by the experiment. The accuracy of the constitutive model is checked and validated against the experimental response at the crack mouth. Under the testing conditions, the creep phases were dominated by a steady phase, and the ice response was overall elastic–viscoplastic; no significant viscoelasticity or major recovery was detected. In addition, there was no clear effect of the creep loading on the fracture properties at crack growth initiation: the failure load and crack opening displacements.

В статье рассматриваются проблемы горизонтальных связей регионов западного порубежья России, находящегося под воздействием геоэкономической турбулентности. На основе статистических методов анализа динамических рядов ввоза и вывоза ключевых наименований продукции проведена оценка динамики и устойчивости межрегиональных торговых потоков. Выявлена противоречивая картина отсутствия явно выраженных трендов на фоне отдельных случаев интенсификации и ослабления межрегиональных потоков, а также повышения амплитудности осцилляции по различным наименованиям и группам регионов. Идентификация случаев кластерного межрегионального взаимодействия и анализ региональных стратегий выявили лишь единичные случаи в межрегиональной кластеризации и стратегических акцентов на развитии горизонтальных связей в западном порубежье.
Aldo Rossi
Authors: Dias Fortes Alexandra
Published: May 2021

Aldo Rossi offers a captivating account of the relationship between human life and material forms. Rossi says that he came to “the great questions”, and to his discovery of Ludwig Wittgenstein and Georg Trakl through Adolf Loos (Rossi 1982: 46). I will outline some connections between Loos, Trakl, and Wittgenstein that might help us to grasp the way in which Rossi’s assertive attitude concerning architecture gradually leans towards “forgetting architecture”. (The goal is not to try and justify how they might have influenced Rossi; rather the aim is to try to understand Rossi’s work with those connections as a backdrop; to outline a constellation of affinities.) The running thread being the internal relation between the object and the subject, i.e., “construction and the artist’s own life” (Lombardo 2003: 97). I will conclude by considering architectural form on the page, that is to say, in Rossi’s plans, “a graphic variation of the handwritten manuscript”, and drawings, “where a line is no longer a line, but writing” (Rossi 1981: 6), and finally by considering what he says about his architecture, namely, that it stands “mute and cold,” though it will still “creak” (Rossi 1981: 44), and give rise to “new meanings”.

Published: May 2021

Infection caused by Pseudomonas aeruginosa is one of the major problems in hospitalized patients which are related to the high mortality. The DNA gyrase B, gyrB reading gene sequence method provides a fast and efficient system for bacterial identification and diagnosis, taxonomic analysis and monitoring of bacteria in the natural environment. Evolution analysis was performed using gene nucleotide sequences for gyrB and 16S rRNA genes. PCR amplifiers were used for the genes under study and their genetic sequences were read. The evolutionary tree was drawn based on the genetic sequences of the classification of P. aeruginosa, compared to the analysis of the 16S rRNA genes, gyrB sequences showed a greater evolutionary deviation of bacteria and may be useful for distinguishing between closely related species. Sequence analysis of 16S rRNA is accurate for identifying unknown bacteria to the genus level. However, the variable gyrB sequence analysis can identify unknown bacteria to the species level. Together with the 16S rRNA analysis, gyrB sequence analysis is considered a useful tool to build the evolutionary relationships of bacteria, especially for the classification of converging bacterial species and controlling the invasive Patho Micobial infection treatment in the hospital.

This study was designed to determine the best olive variety for cultivation in Pakistan. The leaves of eight locally grown varieties were analyzed for levels of moisture, total solids, ash, fat, fibre, protein, K, Ca, Mg, Na, Fe, Mn, Zn and Cu levels. Leaves were then subjected to solvent extraction with each of water ratio in, 75% ethanol, 75% methanol, 95% ethanol and 95% methanol. The extract yield was significantly highest for 75% ethanol extract of all varieties. Significantly highest polyphenol and flavonoid contents were examined for Gemlik leaves extracted with 75% ethanol. We recommend cultivation of Gemlik in Pakistan and extraction of bioactive compounds from olive leaves will be the most efficient with a binary solution of 75% ethanol in water. Further studies should be planned to assess antioxidant, antimicrobial and food preservation properties of olive leaf extract from locally grown varieties.

Authors: Anania Osikemekha Anthony , Olomukoro John Ovie , Enuneku Alex Ajeh
Published: May 2021

The objectives of this study are to assess the trace and heavy metals pollution in the sediments of Ossiomo river, using geospatial mapping, environmetrics and ecological risk indices. The results from the descriptive statistics showed that there was significant difference (P<0.05) of the mean values of Fe, Mn, Cu, Cr, Cd, Pb, Ni and V. A posterior analysis using Duncan multiple regression analysis showed that stations 2 and 3 were significantly different from stations 1 and 4. While, there was no significant difference (P>0.05) in the mean values of Zn across the stations. The results of the relationship of the metals revealed a negative correlation between Fe and Mn with the other metals correspondingly. The results of the Kriging interpolation indicated a strong bull eye colour for stations 2 and 3 (6.42), while stations 1 and 4 were minimal (1.4). The results of the geospatial mapping indicated Fe, Zn and Mn to be the most dominant metals across the stations. The results of the PCA (principal component analysis) yielded 16 variables under 9 components with Eigenvalues >1 in components 1- 6 and these variables explained 99.99 % of the total variance in the sediment. The results of the degree of suitability and sphericity of the PCA revealed a high significant difference at P<0.001. The results of the potential ecological risk index values were very high in station 2 (824.30) and 3 (802.11) correspondingly. That of index of geo-accumulation was generally low (< 2). The findings from this study generally revealed the source apportionment of the trace and heavy metals to come from anthropogenic influences such as farming; fertilizers. Sustainable agriculture is highly recommended in order to reduce the impacts of anthropogenic activities, deterioration of the ecosystem and possible death of the life forms in this watercourse.

Authors: Akash Muhammad Sajid Hamid , Rehman Kanwal , Sabir Shakila , Gul Javeria , Hussain Iqbal
Published: May 2021

Nowadays, pharmaceutical waste has been considered as an environmental micro pollutant due to its unavoidable occurrence in the ecosystem and has become a major health issue. Pharmaceutical products are formulated to therapeutically influence the physiological systems, however, their potential health concerns which contribute in increasing environmental pollution like other most potential environmental pollutants still needs to be taken under consideration by the healthcare professionals and environmental experts. So, the contamination of treated wastewater by pharmaceutical waste and outcome of these compounds in the agricultural environment are of increasing concern and potential risk for the ecosystem. With increasing utilization of treated wastewater and biosolids in agriculture, residues of pharmaceutical and personal care products in these reused resources may contaminate the food produced via plant uptake, constituting a route for human exposure. In this article, the occurrence and behavior of pharmaceuticals waste have been briefly reviewed. Moreover, major concerns associated with exposure of biological systems of both plant and animal origin to the pharmaceutical wastes contaminating the ecosystem have also been discussed here which concluded that standard procedures and protocols should be followed to dispose of the leftovers of pharmaceuticals and/or pharmaceutical wastes.

We describe the case of a seven-year-old child who, following the incidental finding of hypertransaminasemia in the blood tests performed for a lymphadenopathy, is subjected to other blood tests that show a persistent moderate increase in CPK values, supporting the hypothesis of a muscle disease even in the absence of specific symptoms. The diagnostic path seems to point towards a late-onset metabolic myopathy. The occasional finding of hypertransaminases , associated with the finding of high CPK levels in an asymptomatic or paucisymptomatic child, orients the diagnostic path. Excluding hepatic storage disease or viral infectious disease, the differential diagnosis leads to a complex late-onset myopathy such as Pompe disease, a rare but important diagnosis whose prognosis could be dramatically improved by the enzyme replacement therapy.
Desmoplastic small round cell tumor of abdomen: Case report of a very rare sarcoma with diagnostic challenge

Published: May 2021

Introduction: A desmoplastic small round blue cell tumor (DSRCT) is a very rare soft tissue sarcoma. The first case was reported in 1989 by Gerald and Rosai. Diagnosis can be challenging, and a differential diagnosis should be considered when a young patient presents with wide-spread abdominal disease without definitive organ involvement as shown in imaging studies. A typical radiological finding in DSRCT is a dominant solid mass in a retrovesical or rectouterine pouch with widespread peritoneal nodules.

Case Report: In this case report, we present a case of a very rare sarcoma in a young Saudi male patient who presented with abdominal distension and widespread intra-abdominal disease with liver metastases. The dominant mass had a cystic component and was not in a typical site.

Conclusion: Diagnosis of such sarcoma is challenging and it needs the correlation of clinical, radiological, morphological, immunohistochemical, and even genetic data.

Published: May 2021

Student engagement in an online class has always been a challenge to faculty. We all know that online courses can be difficult for some students, and online discussions do not always turn out as planned. How do we maximize our online communication effectiveness? In a case study of an Emotional Intelligence course in a community college setting, we looked at this through a sociological lens and built on the perspective of socialization theories and conceptions to see students quickly become engaged in discussions with their classmates and openly share their concerns. Data was analyzed and lessons learned.
Opuscula Ugaritico-Accadico-Hebraica: Relative Particles, pa'am, and Amraphel
Authors: Wikander Ola
Published: May 2021

The article deals with two questions concerning the relationship between Hebrew, Akkadian, and Ugaritic: the background of the relative particle šeC-/šaC- and the relationship between Hebrew pa'am ("time, foot") and Ugaritic pamt ("time") and p'n ("foot, leg"). In the former case, a model of morphological conflation is argued. In the latter, Northwest Semitic dialectology is discussed, and the origin of the name Amraphel is used as a comparandum and given a partially new explanation involving borrowing from an international scribal koine, which shows difficulty in pronouncing the voiced pharyngeal.

This study was an attempt to examine the quality indicators of Haraz River water inflow and outflow of water of fish farms. This study aimed to prove and assess the water pollution status of Haraz River and investigate the impact of fish farms on river water quality. Sampling was performed in two seasons of summer and autumn of 2015 in seven stations of river water and inflow and outflow of farms water. Quality pollution index includes (temperature, phosphate, nitrate, nitrite, ammonia, electrical conductivity, BOD, COD, PH Were measured. Comparison of the results with the allowable values of Iran code and waste water standards showed that the factors in all samples and both seasons were in the allowable range and the rate of these indicators in autumn is higher than the summer. The amount of ammonia, carbon and total phosphate in summer is higher than the autumn. The findings of the results reveal that the proper quality and cleanliness of Haraz River water in the study area show that the activity of farms doesn’t have a significant effect on the quality index of Haraz River water.
Identification of Suitable Contrast Enhancement Technique for Improving the Quality of Astrocytoma Histopathological Images.
Authors: DZULKIFLI FAHMI AKMAL
Published: May 2021

Contrast enhancement plays an important part in image processing. In histology, the application of a contrast enhancement technique is necessary since it can help pathologists in diagnosing the sample slides by increasing the visibility of the morphological and features of cells in an image. Various techniques have been proposed to enhance the contrast of microscopic images. Thus, this paper aimed to study the effectiveness of contrast enhancement techniques in enhancing the Ki67 images of astrocytoma. Three contrast enhancement techniques consist of contrast stretching, histogram equalization, and CLAHE techniques were proposed to enhance the sample images. The performance of each technique was compared by computing seven quantitative measures. The CLAHE technique was preferred for enhancing the contrast of the astrocytoma images. This technique produces good results especially in contrast enhancement, edge conservation and enhancement, brightness preservation, and minimum distortions to the enhanced images.

This study was carried out to understand the dynamics of carbon and phosphorus biogeochemical cycles in native forest and horticultural areas. Soilsamples were collected from native forest and horticultural areas, in four municipalities in the Metropolitan Region of Curitiba, Brazil, and evaluated for: carbon, nitrogen and phosphorus of soil microbial biomass (MBC, MBN and MBP, respectively), total organic carbon (TOC), total nitrogen (TN), total phosphorus (TP), inorganic phosphorus (iP), organic phosphorus (oP) and available phosphorus (aP. Soil suspensions diluted at 10-4were spread on plates and phosphate solubilizing bacteria (PSB) were counted. The analyses showed that horticultural areas soils accumulated 43% more TP whereas they lost 23% of TOC and 19% of TN comparing to native areas. 69% of TP in the native areas was organic (oP) whereas 59% of TP in the horticultural areas was inorganic (iP). Horticultural areas had lower numbers of colony forming unities of PSB than native areas. PSB was positively correlated with the ratio of MBC to TOC (qMic), which in turn, was negatively correlated with TOC and TN. Changes in the soil P fractions suggested a shift inthe soil community bacterial structure and in the values of soil microbial biomass of the two different soil ecosystems. The excessive P addition may stimulate soil microbial attack to soil organic matter reserves, whichmay have consequences for maintenance of soil quality and agriculture sustainability

The present study aimed to evaluate the effect of seed coating with Si in response to infection in a cultivar susceptible and resistant to Colletotrichum lindemuthianum, on the physiological and health potential of seeds and seedlings, during the initial development of bean culture. The experiment was carried out in a completely randomizeddesign, in a 2 × 2 × 2 factorial scheme, with four replications, where the factors were: cultivar (BRS Esplendor and IPR Tuiuiú), silicate application (with and without Agrosilício® coating) and inoculation (seeds inoculated or not with C. lindemuthianum). In the evaluation of the initial development of the culture, the following variables were measured: germination, first count of the germination test, emergence, emergence speed index (IVE), total seedling length, shoot and root length, total dry mass, aerial part dry matter, root dry matter and aerial part dry matter at 15 days after sowing (DAS). The incidence of C. lindemuthianumin beans was determined by the paper roll method. Covering the seeds with Si reduces the incidence and severity of C. lindemuthianumand provides greater growth of bean seedlings. The effect of responses potentiated by Si is more expressive in the cultivar of greater susceptibility.

Soils provide a broad set of vital ecosystem services and sustains the production of food and fibers, balancing the ecosystem. Thus, from the perspective of soil quality, it is defined as an ability to balance within the ecosystem to sustain biological productivity, promoting the health of plants and animals, being evaluated by traditional indicators as physical, chemical and biological indicators, so the present work aims to estimate the soil quality index using multivariate models using soil biological attributes and validation with growth variables of the bioindicator plant. The study was developed in the agricultural area in P. Prudente, SP, the points collected were georeferenced, collections in depth of 0 -20 cm, microbiological analysis, microbial carbon and nitrogen biomass, dehydrogenase, respiration and microbial coefficient, having a bioindicator plant curly lettuce (Lucy Brown) as a validator of the soil. The results were discovered using the PCA model for the identification of autos vectors and autos values, grouping and identifying their collinearities, linear regression, r-pearson validation and cluster heuristic analysis. The microbial attributes and the bioindicator plant discriminated the agricultural areas evaluated with establishment and validation of SQI. The metabolic coefficient and N of the microbial biomass dissipation of the highest covariance values by multivariate analysis. The reforestation area with native species (SQI0.782%) and the livestock crop integration system (SQI0.765%) were evaluated as areas with better soil quality

The use of pre-emergent herbicides is an important tool in weedmanagement. Sulfentrazone + diuron mixture was recently launched ontothe market. The objectiveof this work was to evaluate the weed control and the agronomic performance of soybean in response to application of sulfentrazone + diurondoses in pre-emergence. The experiment was conducted in Londrina PR, in an oxisol. The treatments were doses ofsulfentrazone + diuron (62 + 123, 123 + 245, 184 + 368, 245 + 490, 306 + 613 e 368 + 735 g a.i.ha-1). In addition to these treatments, isolated applications of sulfentrazone (245 g a.i.ha-1) and diuron (490 g a.i.ha-1) were evaluated, as well as a weedyand aweed-freecontrol. For the weed control, the wild radish(Raphanus raphanistrum)and itchgrass (Rottboellia cochinchinensis) emergencewere evaluated. In soybean, photosystem II (PSII)activity, stand, plant height, number of podsper plant, height of insertion of the first pod, number of nodes per plant, mass of a thousand grains and grain yield were evaluated. Results show that the mixture of sulfentrazone + diuron resulted in less than 50% wild radish control, regardless of the dose evaluated. However, for itchgrass, the control was greater than 90% in doses from 123 g sulfentrazone + 245g diurona.i.ha-1. Regarding thesoybeancrop, in doses from 245 g sulfentrazone + 490 g diuron a.i. ha-1 there was a greater number of pods per plant and higher grain yield, of about3,000 kg ha-1. The application of herbicides led to a transient inhibition of PSIIactivity, which did not result in a reduction in crop grainyield, indicating plant recovery. Therefore, the mixture of sulfentrazone + diuron is a good alternative for the weed management in pre-emergence of soybean, and should be positioned according to the history of fieldinfestation.
