Waves on a compressed floating ice plate caused by motion of a dipole in water

Abstract In the linear approximation, we study wave motions of a compressed elastic ice sheet caused by the motion of a two-dimensional dipole in the water beneath the sheet. The fluid flow is described by the potential theory, while the ice sheet is modelled through a thin elastic plate floating on the water surface. The solution for the vertical displacement of the ice sheet is derived for a transient dipole undergoing arbitrary two-dimensional motion. Three cases are considered in detail when the dipole moves horizontally with a uniform speed at some depth or horizontally oscillates, or moves and oscillates. The formulae for the plate displacement are derived for the fluid of finite depth, but then analysed in detail for the infinitely deep case. We show that the character of the solutions is different in the different domains of the parameter plane and classify the possible cases. Then we calculate the wave patterns on the plate for the different regimes of dipole motion and typical values of plate parameters. The studied problem can be considered as the simplified model of motion of a circular cylinder in a water under an ice cover. In the last section we compare the characteristics of wave motions onsetting in the far-field zone of the flow around a circular cylinder and its dipole approximation and show that the difference in the wave characteristics and force loads for these two cases is small and quickly vanishes when the ice plate thickness increases. In conclusion, we present estimates of amplitudes and wavelengths of wave perturbations for the real oceanic conditions.
Preferential retention of the slowly evolving gene in pairs of duplicates in angiosperm genomes

Gene duplication provides raw material for functional innovation, but gene duplicability varies considerably. Previous studies have found widespread asymmetrical sequence evolution between paralogs. However, it remains unknown whether the rate of evolution among paralogs affects their propensity of being retained after another round of whole‐genome duplication (WGD). In this study, we investigated gene groups that have experienced two successive WGDs to determine which of two older duplicates with different evolutionary rates was more likely to retain both younger duplicates. To uncouple the measurement of evolutionary rates from any assignment of duplicate or singleton status, we measured the evolutionary rates of singleton genes in out‐lineages but classified these singleton genes according to whether they are retained or not in a crown group of species. We found that genes that retained younger duplicates in the crown group of genomes were more constrained prior to the younger duplication event than those that failed to leave duplicates. In addition, we also found that the retained clades have more genes in out‐lineages. Subsequent analyses showed that genes in the retained clades were expressed more broadly and highly than genes in the singleton clades. We concluded that the set of repeatedly retained genes after two WGDs is biased toward slowly evolving genes in angiosperms, suggesting that the potential of genes for both functional conservation and divergence likely affects their propensity of being retained after WGD in angiosperms.
Development of a Model for the Establishment of a Hydro Electric Power Generating Plant

Nigeria as a nation has suffered a lot when it comes to the availability of electricity. A clear comparison between this nation’s electric power supply and other countries revealed the present incessant electric power supply in the country. The average power per capital (watts per person) in the United States is 1,377 Watts. In Canada, it is as high as 1,704 Watts per person and in South Africa; it is 445 Watts per person. The average power per capital in Australia is 1,112 Watts and in New Zealand it is 1,020 W per person. Whereas, the average power per capital (watts per person) in Nigeria is 14 W person. The power system structure is characterized with a lot of faults and outages. These electric power problem has destroyed the industrial processes in the country. As a result, unemployment has increased in the country. As at February, 2020, according to the Federal Government of Nigeria, the number of unemployed youths in the country is 23 million. Data from the International Transparency in the United State stated that there are 40 million unemployed youths in the country. This has increased crime rates among the youths. The country experience a high level of hardship, insecurity and socio-economic disorder as results. Therefore, there is an urgent need to solve this incessant supply of electric power in the country. Hence, a detail study of Akure132/33kV substation Network of the Benin Electricity Distribution Company under which there are 84,264 customers was carried out.
Polymorphic Memory: A Hybrid Approach for Utilizing On-Chip Memory in Manycore Systems

The key challenges of manycore systems are the large amount of memory and high bandwidth required to run many applications. Three-dimesnional integrated on-chip memory is a promising candidate for addressing these challenges. The advent of on-chip memory has provided new opportunities to rethink traditional memory hierarchies and their management. In this study, we propose a polymorphic memory as a hybrid approach when using on-chip memory. In contrast to previous studies, we use the on-chip memory as both a main memory (called M1 memory) and a Dynamic Random Access Memory (DRAM) cache (called M2 cache). The main memory consists of M1 memory and a conventional DRAM memory called M2 memory. To achieve high performance when running many applications on this memory architecture, we propose management techniques for the main memory with M1 and M2 memories and for polymorphic memory with dynamic memory allocations for many applications in a manycore system. The first technique is to move frequently accessed pages to M1 memory via hardware monitoring in a memory controller. The second is M1 memory partitioning to mitigate contention problems among many processes. Finally, we propose a method to use M2 cache between a conventional last-level cache and M2 memory, and we determine the best cache size for improving the performance with polymorphic memory. The proposed schemes are evaluated with the SPEC CPU2006 benchmark, and the experimental results show that the proposed approaches can improve the performance under various workloads of the benchmark. The performance evaluation confirms that the average performance improvement of polymorphic memory is 21.7%, with 0.026 standard deviation for the normalized results, compared to the previous method of using on-chip memory as a last-level cache.
Soil microbial properties and functional diversity in response to sewage sludge amendments

ABSTRACT Soil organic matter has vital role in maintaining important soil functions. Consequently, using sewage sludge as soil organic amendment is considered one of the agricultural practices for improving soil fertility, which is also a safe approach for its disposal. The present research was carried out to analyze the different microbial activities and functional diversity of agricultural soil with regard to sewage sludge application. A laboratory experiment was set up by taking the agricultural soil from Haryana Agricultural University fields and amended with 5, 10, 20, 30 and 50 t ha−1 of sewage sludge. It was observed that soil microbial biomass increased upto 60% and potential activities of dehydrogenase, alkaline phosphatase and urease enzymes increased upto 50–55% with increasing application rates of sewage sludge. In addition the community-level physiological profiling technique (CLPP) based on carbon source utilization was used to determine the microbial functional diversity of soil. The results indicated higher functional diversity of microbial population capable of exploiting different carbon substrates with sewage sludge application. These results are imperative for improving the approach of sewage sludge application to the agricultural soil in consideration of increasing soil fertility with reducing the use of chemical fertilizers.
Kalorimetrische Untersuchungen zum Lösungsverhalten von Polyacrylsäure und Poly(natriumacrylat) in Wasser, Formamid und Ethylenglykol

Heats of solution and heats of dilution of poly(acrylic acid) (PAAcH), poly(sodium acrylate) (PAAcNa), and poly(acrylamide-co-sodium acrylate) (1:1) (PAAm/PAAcNa) in water, formamide (FA), and ethylene glycol (EG) as measured at 25°C, are reported. While for PAAcH/H2O and PAAcH/EG only minor caloric effects are observed, the heats of solution for PAAcNa/H2O are strongly exothermic as a result of dissociation of the polysalt. Heats of dilution in this system are endothermic because of the hydrolysis reaction. PAAcH/FA shows large negative enthalpies on dissolution as well as on dilution. This is due to the dissoziation of the COOH-groups which is much more pronounced in FA than in the aqueous system because formamide has a greater ionizing capability. Comparison between the behaviour of copolymer PAAm/PAAcNa and physical admixing of the homopolymers confirms the specific neighbouring group interaction of carboxylate and carbonamide groups along the same chain. Comparing the calorimetric results for PAAcH with those for the low-molecular-weight model compound propionic acid, it becomes evident that the differences are mostly due to the different state of order of the pure compounds, namely, due to the chain structure, the COOH-groups in the polymers are not as flexible as in the monomers. Therefore, in the pure polymer less hydrogen bonds are formed than in the pure propionic acid. The calorimetric results are discussed in the light of previous work on viscosimetric dilute solution behaviour of these systems, showing the consistency of the different experimental findings.
Change of the chemical composition of potato plants when applying organic fertilizers under the conditions of the Chuvash Republic

The experiments were carried out with the use of urban wastewater sludge from the city of Novocheboksarsk (Russia), crushed horns and hooves of cattle (horn-hoofed sawdust), semi-rotted cattle manure and wood ash on typical gray forest heavy loamy soil. By using sewage sludge as fertilizer for potatoes, the yield of tubers increased by almost 50%. However, the quality of potatoes in the first year of setting the experiment (2017) with the use of sewage sludge deteriorated: the ratio of K2O/CaO in tubers decreased more than twice, the starch content decreased, and the amount of nitrates increased. The reason for the deterioration in the quality of tubers is the violation of the ratio of chemical elements (Ca, Mg and K) in the wastewater sludge, which led to the immobilization of potassium in the soil by microorganisms. The main indicators of the fertility of a typical gray forest soil at the end of the experiment improved significantly - the content of organic matter, mobile phosphorus and exchangeable potassium increased significantly. The possibility of one-time use of sewage sludge in increasing the fertility of depleted and degraded soils with the simultaneous use of potash mineral fertilizers to optimize the balance of potato nutrients in the soil is allowed.

Coupling PCSWMM and WASP to Evaluate Green Stormwater Infrastructure Impacts to Storm Sediment Loads in an Urban Watershed

We coupled rainfall–runoff and instream water quality models to evaluate total suspended solids (TSS) in Wissahickon Creek, a mid‐sized urban stream near Philadelphia, Pennsylvania. Using stormwater runoff and instream field data, we calibrated the model at a subdaily scale and focused on storm responses. We demonstrate that treating event mean concentrations as a calibration parameter rather than a fixed input can substantially improve model performance. Urban stormwater TSS concentrations vary widely in time and space and are difficult to represent simply. Suspended and deposited sediment pose independent stressors to stream biota and model results suggest that both currently impair stream health in Wissahickon Creek. Retrofitting existing detention basins to prioritize infiltration reduced instream TSS loads by 20%, suggesting that infiltration mitigates sediment more effectively than detention. Infiltrating stormwater from 30% of the watershed reduced instream TSS loads by 47% and cut the frequency of TSS exceeding 100 mg/L by half. Settled loads and the frequency of high TSS values were reduced by a smaller fraction than suspended loads and duration at high TSS values. A widely distributed network of infiltration‐focused projects is an effective stormwater management strategy to mitigate sediment stress. Coupling rainfall–runoff and water quality models is an important way to integrate watershed‐wide impacts and evaluate how management directly affects urban stream health.
Cultivable cellulolytic fungi isolated from the gut of Amazonian aquatic insects

ABSTRACT Filamentous fungi have been targeted by bioprospecting studies because they are effective producers of extracellular enzymes that can potentially be used by the bioindustry. In this study, we isolated filamentous fungi from the guts of Amazonian aquatic insect larvae to evaluate their cellulolytic activity. We collected 69 larvae of shredder insects of three genera: Phylloicus (Trichoptera: Calamoceratidae), Triplectides (Trichoptera: Leptoceridae) and Stenochironomus (Diptera: Chironomidae) in ten streams from a protected area in the central Brazilian Amazon. Production of mycelia was elaborated in PDA (Potato Dextrose Agar) medium. The isolates were transferred to a synthetic medium with carboxymethyl cellulose, and Congo red was used to determine the enzymatic index. The hydrolysis halo, indicating the production of cellulases, was observed in 175 fungal isolates (70% of the total), of which 25 had an enzymatic index ≥ 2.0 and belonged to seven fungal genera. The fungal taxa Cladosporium, Gliocephalotrichum, Penicillium, Pestalotiopsis, Talaromyces, Trichoderma and Umbelopsis were isolated from guts of Phylloicus, Triplectides and Stenochironomus, which are traditionally used in biotechnological applications. Our results indicate the cellulolytic potential of fungi associated with the guts of aquatic Amazonian insects.

Furthermore, Brand Awareness and Brand Image owned by AirAsia give a positive impression of a refund to gain consumer trust.
A Novel Integrated Prognosis & Diagnosis System for Lung Cancer Disease Detection using Soft Computing Techniques

Nowadays, lung cancer is one of the ranking first causes of mortality worldwide among men and women. Although there are a lot of treatment options like surgery, radiotherapy, and chemotherapy, five-year survival rate for patients is quite low. However, survival rate may go up to 54% in case lung cancer is identified in an early stage. Therefore, early detection of lung cancer is vital to decrease lung cancer mortality. Medical Experts are continuously trying to find the best solution for the early prediction and diagnosis of Lung Cancer Disease; in this Research work, an attempt has been made to design and develop a novel integrated soft computing predictive system to handle various types of patients’ clinical data to diagnose the lung cancer disease. Here data mining techniques are used to handle the numeric and textual data, image processing techniques are used to handle CT scan images, neural networks are used to train the lung cancer patient images, and fuzzy inference mechanism is used to predict the lung cancer stages. This integrated approach results in detection of lung cancer disease with Prognosis and suggesting diagnosis by the expert system for lung cancer disease. Even in cases of small-sized nodules (3–10 mm), the proposed system is able to determine the nodule type with 96% accuracy.
Doctrine de la découverte : préciser les enjeux théologiques d’une revendication autochtone

La doctrine de la découverte est issue de bulles papales du XVe siècle et de leur tradition d’interprétation. Elle est réputée avoir fortement entravé la reconnaissance de droits ancestraux des peuples autochtones, en droit international et dans la jurisprudence des états coloniaux jusqu’à aujourd’hui. Ainsi au Canada, le rapport final de la Commission de vérité et réconciliation réclame l’abolition officielle de la doctrine de la découverte par le Gouvernement, les Églises et les coalitions œcuméniques. Cependant, le Saint-Siège se refuse toujours à le faire, en plaidant que la doctrine a été invalidée de fait par divers développements historiques et qu’elle relève maintenant exclusivement des états et des tribunaux séculiers. Qu’en est-il ? Cet article retrace des étapes marquantes dans l’histoire de la doctrine, depuis les bulles Dum Diversas (1452), Romanus Pontifex (1455) et Inter Caetera (1493), jusqu’à deux jugements marquants de la Cour suprême des États-Unis et de la Cour suprême du Canada qui ont inscrit la doctrine dans la jurisprudence au XIXe siècle. Il apparaît que la doctrine s’est largement affranchie des bulles papales pour prendre appui sur des sources ultérieures. Cependant, l’évolution de la doctrine de la découverte invite à l’aborder au-delà de la question de l’abolition des bulles concernées, pour une étude à trois volets : 1) historique et conceptuel, en théologie et en droit ; 2) critique culturelle décoloniale du christianisme ; et 3) étude empirique de pratiques qui déconstruisent la doctrine de la découverte, dans des mouvements chrétiens et non confessionnels au sein de la société civile.
Validation of a highly sensitive method for the determination of neonicotinoid insecticides residues in honeybees by liquid chromatography with electrospray tandem mass spectrometry

The validation of a multi-residue method for the determination of five neonicotinoid insecticides (imidacloprid, clothianidin, acetamiprid, thiacloprid and thiamethoxam) in honeybees is described. The method involves the extraction of pesticides using acetonitrile and liquid partitioning with n-hexane. One clean-up is then performed on a florisil cartridge (1 g, 6 mL) and the extract is analysed by liquid chromatography-electrospray ionisation-tandem mass spectrometry (LC-ESI-MS/MS). The recovery data were obtained by spiking honeybees samples free of pesticides at two concentration levels of the various neonicotinoids. The recoveries were in the range between 93.3 and 104.0% with relative standard deviation (RSD) less than 20%. The limit of quantification (LOQ) was 0.5 ng g−1 (corresponding to 0.05 ng bee−1) for all pesticides except for acetamiprid which was 1 ng g−1 (corresponding to 0.1 ng bee−1).
A comprehensive review of distribution generation integrated DC microgrid protection: issues, strategies, and future direction

The evolution of small‐scaled distributed generators and emerging power electronic devices opens up a new arena of power generation, distribution, and consumption. Operationally, the DC microgrid has attracted significant attention as it offers considerable safety benefits, cost‐effectiveness, energy efficiency, and reliability as compared to traditional AC microgrid systems. Looking at the protection aspects, the DC microgrid has some serious issues both for low‐voltage and mid‐voltage DC system. It needs to be focused on bidirectional power flow, non‐zero crossing point, detection and mitigation of grounding faults, high value of fault current, etc., for an adequate solution. In recent times, these issues are considered by various researchers to arrive at a robust and reliable approach toward protecting the DC microgrid. But certain important areas are still out of sight for researchers. In a blend of conventional and modern approaches, there are many hindrances in developing a flexible universal protective scheme. This work focuses on the protection aspects parallel with the challenges and tried to unearth the loopholes which open up a wider area of research to develop a more robust protective architecture. An extensive review has been done systematically and chronologically keeping in mind the DC microgrid architecture, standards, protection hurdles, traditional as well as latest protective measures, and suggested some reliable improvements. In addition, the futuristic possibility to invent a novel comprehensive approach based on the best technology and techniques is presented in a more secure, reliable, and efficient protection system to combat the power system faults, keeping in view the different modes of operation and configuration of the microgrid.
