CONSTRUCTIVISTIC PATHS IN TEACHING PHYSICS: FROM INTERACTIVE EXPERIMENTS TO STEP-BY-STEP TEXTBOOKS

Teaching Physics, in-between theory and technical applications is nowadays a tedious task. Apparent abundance of web resources makes access to information easy, but its use by pupils is quite unclear. These difficulties, added to less importance held by physics nowadays than in the last decades, inside the na tional educative system, caused in many countries a fall of interest in studying science and technology. Within several national and international programs, involving mainly Poland and Italy, various recipes for school education at lower and higher secondary level were developed in our group. All these recipes were oriented towards real experiments and constructing the discovery paths with pupils. The school (and extra-scholastic activities for primary-age pupils) included: collections of simple experiments “Physics and Toys”, interactive lectures for children, itinerary exhibitions, innovative textbooks inviting the reader to a heuristic dialog, computer-guided experiments, and collections of problems in physic solved step-by-step. We resume some of these implementations and draw main results. Actions were undertaken with three cultural goals: trigger a wide interest in physics through “Fun in Physics” activities, improve didactical efficiency at schools, induce students’ initiative in an independent discovery of science. In detail, for a lower secondary school simple interactive experiments on electromagnetism were introduced, and a textbook on mechanics. For higher secondary schools – a textbook on modern physics and computer-guided experiments; for children aged 5-10 – interactive lectures on mechanics, electricity, acoustics. Evaluations were performed by qualitative and quantitative measures, in Poland and Italy, in collaboration with several teachers and PhD students. teachers and pupils. However, partial and sporadic actions do not lead to significant results. Only con jugated implementations of new experimental tools (real objects) and didactical methods (inquiry-based teaching) shows achievements congruent with the Lisbon EU declaration on Knowledge-based Societies (eu commission White paper: education and training, 1995) .

IDENTIFICATION OF POLYMER SYNERGY WITH HELP OF DOE

Ophthalmic solutions undergo rapid clearance from eye due to instant tear drainage, lower volume of cul-de-sac and lesser contact time with eye. All these drawbacks of ophthalmic solutions results in less efficacious product or requires repeated dosing. Repeated dosing of formulation could lead to lesser patient compliance and possible adverse effects. There are numerous approved polymeric ingredients available for ophthalmic use; however less information is available on their synergies. Hence there was a need to identify synergies among various polymeric ingredients with increased adhesiveness for sustained release ophthalmic formulations. Formulation adhesiveness is the function of viscosity being directly proportional; it plays a major role to sustain the drug release by increasing the contact time in eye with help of muco-adhesive forces or by polymer inter-penetrated network (IPN). Choice of selection of polymeric ingredients were based on their individual viscosities. Significant synergies were considered for those combinations which have higher viscosities compared to their individual viscosities at lower concentrations. The identified synergistic combination was also studied for stress study with the impact of pH, buffers and temperature during steam sterilization process.
Image matching with multi medium Delaunay triangulation

The Delaunay triangulation is well-known in the field of computational geometry, holography, networking and fingerprint matching. In our case, a matching image from the image database is proposed by using the Delaunay triangulation, which has the ability to perform multidimensional in matching. To prevent problems on the complexity of the dimensions, we proposed a method for the Delaunay triangulation matching with several medium dimensions from all feature vectors. Then, apply to match all the image’s databases. In this paper, we use the color histogram as a representation of multidimensional feature vectors to test the matching in several environments and illustrate the main issues. The results in matching accuracy are satisfactory

SYNTHESIS AND CHARACTERIZATION OF MURVA ENCAPSULATED CHITOSAN NANOPARTICLES FOR THE TREATMENT OF DIABETES MELLITUS

Design and development of herbal novel drug delivery system has become a frontier research in the novel drug delivery system arena. Murva is a potent phytomolecule obtained from Maerua oblongifolia of family capparaceae, has been traditionally used to cure various diseases. The limitations of herbal drugs are poor biodistribution and instability. In order to improve the therapeutic efficacy and stability, the herbal drug Murva was encapsulated in chitosan nanoparticles. Chitosan nanoparticles containing Murva (CNP1-CNP5) were synthesized by ionic gelation of chitosan with tripolyphosphate anions (TPP) resulting in particles size smaller than 650nm. The encapsulation efficiency of nanoformulations was over 41.5%. The nanoformulations exhibited slow and sustained in vitro release over 99% of drug from the Murva encapsulated chitosan nanoparticles after 24 hours. The synthesized nanoformulations were found to be stable, biocompatible and produced an enhancement of anti-diabetic activity.
Altitudinal and climatic adaptation is mediated by flowering traits and FRI , FLC and PhyC genes in Arabidopsis thaliana

Extensive natural variation has been described for the timing of flowering initiation in many annual plants including the model wild species Arabidopsis thaliana , which is presumed to be involved in adaptation to different climates. However, the environmental factors that might shape this genetic variation, as well as the molecular bases of climatic adaptation by modifications of flowering time remain mostly unknown. To approach both goals, we characterized the flowering behavior in relation to vernalization of 182 A. thaliana wild genotypes collected in a native region spanning a broad climatic range. Phenotype-environment association analyses identified strong altitudinal clines (0-2600 m) in seven out of nine flowering related traits. Altitudinal clines were dissected in terms of minimum winter temperature and precipitation indicating that these are the main climatic factors that might act as selective pressures on flowering traits. In addition, we used an association analysis approach with four candidate genes, FRI , FLC , PhyC and CRY2, to decipher the genetic bases of this variation. Eleven different loss-of-function FRI alleles of low frequency accounted for up to 16% of the variation for most traits. Furthermore, an FLC allelic series of six novel putative loss- and change-of-function alleles, with low to moderate frequency, revealed that a broader FLC functional diversification might contribute to flowering variation. Finally, environment-genotype association analyses showed that the spatial patterns of FRI , FLC and PhyC polymorphisms are significantly associated with winter temperatures and spring and winter precipitations, respectively. These results support that allelic variation in these genes is involved in climatic adaptation. The effects of tested LN (or VLN) onto FT (or VFT) using flowering data of all accessions. The percentage of NV individuals per accession that remained in vegetative phase at the end of the experiment was used as a quantitative measurement of the obligate vernalization requirement (OVR). Accessions that completely failed to flower in NV conditions were considered to have a qualitative obligate requirement of vernalization. The ratios LN/FT and VLN/VFT of the flowering individuals were estimated as a measurement of the average rate of leaf production, a major component of vegetative growth. Mean phenotypic values of 7-15 individuals per
Pasting Schemes for the Monoidal Biclosed Structure on

Using the theory of pasting presentations, developed in chapter 2, I give a detailed description of the tensor product on ! -categories, which extends Gray's tensor product on 2-categories and which is closely related to Brown-Higgins's tensor product on ! -groupoids. Immediate consequences are a general and uniform deenition of higher dimensional lax natural transformations, and a nice and transparent description of the corresponding internal homs. Further consequences will be in the development of a theory for weak n-categories, since both tensor products and lax structures are crucial in this.

1Department of Urology, Nanjing Medical University, Nanjing, People’s Republic of China; 2Department of Urology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, People’s Republic of China Introduction:: Enhanced recovery after surgery (ERAS) protocols aim to optimize patient recovery after major surgery. Our study was to examine the evidence of the effectiveness of interventions designed to improve patient outcomes after radical cystectomy. Design: Systematic review and meta-analysis. Data Sources: PubMed, Medline, Embase, Cochrane from January 2005 to January 2021 without language restrictions. Eligibility Criteria: Randomized and non-randomized controlled studies implementing ERAS measuring its interventions on rates of postoperative complications, 30-day readmission, length of stay (LOS) and bowel function after radical cystectomy. Data Extraction and Synthesis: Two members of the investigating team independently selected studies and evaluated bias using the Cochrane collaboration tool. Meta-analysis of all comparative studies used inversed-weighted, fixedeffects models and random effects models to pool results. Publication bias was graphically assessed using contour-enhanced funnel plots and the Egger’s test of funnel plot symmetry. Results: Fifteen studies were included in our meta-analysis; we observed that ERAS decreased the time for the first bowel movement (standardized mean difference [SMD]: – 1.30, 95% CI −1.90 to −0.70, P<0.00001) and shortened the length of stay (LOS) ([SMD]: – 0.49, 95% CI −0.77 to −0.20, (P < 0.00001)); however, 30-day readmission (risk ratio [RR]: 0.97,95% [CI] 0.73 to 1.28, P=0.52) and the overall postoperative complication rate (risk ratio [RR]: 0.98,95% confidence interval [CI]: 0.88 to 1.09, P= 0.41) showed no significant difference.
Real-time FPGA implementation of the DTC Power Control for DFIG-Generators applied to wind turbines

— In this paper we develops a new control strategy for extracting and controlling the power of the Doubly-Fed Induction Generator (DFIG) applied to wind turbines. A new contribution for the regulation of the active and reactive power is presented, with the aim of an injection to the distribution network. The proposed model in this paper is based on direct torque control (DTC), which is based on performance estimators to improve the quality of the system. The energy quality genered by wind system will be injected into the distribution network according to international standards. Finally, the results of the real-time implementation of the control are implemented on the Matlab / Simulink Xilinx System Generator environment. The entire wind turbine system has been tested in laboratory conditions using the test bench. Simulation and experimental tests show the high dynamic performance and robustness of the proposed control.
An Innovative Olive P â t é with Nutraceutical Properties

: Food plays a central role in health, especially through consumption of plant-derived foods. Functional foods, supplements, and nutraceuticals are increasingly entering the market to respond to consumer demand for healthy products. They are foods, supplements, and ingredients which o ﬀ er health beneﬁts beyond the standard nutritional value. Some beneﬁts are associated with phenolic compounds and phytochemicals with antioxidant properties. An olive p â t é (OP) was added with antioxidants derived from olive mill wastewater (OMWW) to obtain a functional product rich in phenolic compounds. The olive p â t é is produced from the ground olive pericarp, which shows an excellent natural antioxidant content. The OMWW is a waste product from oil processing, which is also rich in phenolic compounds. The result was a product rich in trans-resveratrol, OH tyrosol, and tyrosol in concentrations such as satisfying the European community’s claims regarding the possible antioxidant action on plasma lipids with excellent shelf-life stability. The total phenolic content was assayed by a colorimetric method, the antioxidant activity by the ABTS [(2,2 (cid:48) -azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)] test, the phenolic proﬁle by Q Exactive Orbitrap LC-MS / MS. The shelf-life stability was conﬁrmed by yeast, molds, and total microbial count, pH, and water activity determinations, and the best pasteurization parameters were determined. The palatability was judged as excellent.
Estimation and evaluation of high-resolution soil moisture from merged model and Earth observation data in the Great Britain Remote Sensing of Environment

Soil moisture is an important component of the Earth system and plays a key role in land-atmosphere in- teractions. Remote sensing of soil moisture is of great scientific interest and the scientific community has made significant progress in soil moisture estimation using Earth observations. Currently, several satellite-based coarse spatial resolution soil moisture datasets have been produced and widely used for various applications in climate science, hydrology, ecosystem research and agriculture. Owing to the strong demand for soil moisture data with high spatial resolution for regional applications, much effort has recently been devoted to the generation of high spatial resolution soil moisture data from either high-resolution satellite observations or by downscaling existing coarse-resolution satellite-based soil moisture datasets. In addition, land surface models provide an alternative way to obtain consistent high-resolution soil moisture information when forced with high-resolution inputs. The aim of this study is to create and evaluate high-resolution soil moisture products derived from multiple sources including satellite observations and land surface model simulations. The JULES-CHESS simulated soil moisture and satellite-based soil moisture datasets including SMAP L3E, SMAP L4, SMOS L4, Sentinel 1, ASCAT, and Sentinel 1/SMAP combined products were first validated against observed soil moisture from COSMOS-UK, a network of in-situ cosmic-ray based sensors. Second, an approach based on triple collocation was applied to compare these satellite products in the absence of a known reference dataset. Third, a combined soil moisture product was generated to integrate the better-performing soil moisture estimates based on triple collocation error estimation and a least-squares merging scheme. From further evaluation, it is found that the merged soil moisture integrates the characteristics of model simulation and satellite observations and particularly improves the limited temporal variability of the JULES-CHESS simulation. Therefore, we conclude that the triple collocation merging scheme is a simple and reliable way to combine satellite-based soil moisture products with outputs from the JULES-CHESS simulation for estimating model-data fused high-resolution soil moisture for the British mainland.
Imaging and Analysis of Pseudomonas aeruginosa Swarming and Rhamnolipid Production (cid:1) †

Many bacteria spread over surfaces by “swarming” in groups. A problem for scientists who study swarming is the acquisition of statistically signiﬁcant data that distinguish two observations or detail the temporal patterns and two-dimensional heterogeneities that occur. It is currently difﬁcult to quantify differences between observed swarm phenotypes. Here, we present a method for acquisition of temporal surface motility data using time-lapse ﬂuorescence and bioluminescence imaging. We speciﬁcally demonstrate three applications of our technique with the bacterium Pseudomonas aeruginosa . First, we quantify the temporal distribution of P. aeruginosa cells tagged with green ﬂuorescent protein (GFP) and the surfactant rhamnolipid stained with the lipid dye Nile red.
Water input and water release from the subducting Nazca Plate along southern Central Chile (33°S–46°S)

The age of the subducting Nazca Plate off Chile increases northward from 0 Ma at the Chile Triple Junction (46°S) to 37 Ma at the latitude of Valparaíso (32°S). Age‐related variations in the thermal state of the subducting plate impact on (a) the water influx to the subduction zone, as well as on (b) the volumes of water that are released under the continental fore arc or, alternatively, carried beyond the arc. Southern Central Chile is an ideal setting to study this effect, because other factors for the subduction zone water budget appear constant. We determine the water influx by calculating the crustal water uptake and by modeling the upper mantle serpentinization at the outer rise of the Chile Trench. The water release under fore arc and arc is determined by coupling FEM thermal models of the subducting plate with stability fields of water‐releasing mineral reactions for upper and lower crust and hydrated mantle. Results show that both the influx of water stored in, and the outflux of water released from upper crust, lower crust, and mantle vary drastically over segment boundaries. In particular, the oldest and coldest segments carry roughly twice as much water into the subduction zone as the youngest and hottest segments, but their release flux to the fore arc is only about one fourth of the latter. This high variability over a subduction zone of <1500 km length shows that it is insufficient to consider subduction zones as uniform entities in global estimates of subduction zone fluxes.
OPEN SOURCE OCR WORKFLOWS FOR HISTORICAL RESEARCH

This paper presents an evaluation of open source OCR for supporting research on material in small-to medium-scale historical archives. Our approach was to develop a workflow engine to support the easy customization of the OCR process towards the historical materials. Commercial OCR often fails to deliver sufficient results here, as their processing is optimized towards large-scale commercially-relevant collections. Our paper demonstrates that such a workflow approach allows users to combine commercial engines’ ability to read a wider range of character sets with the flexibility of open source tools in terms of customisable pre-processing and layout analysis. We present two of our case studies, which demonstrate how this can be achieved and how OCR can be embedded into wider digitally-enabled historical research. The first case study produces high-quality research-oriented digitisation outputs, utilizing services that we developed to allow for the direct linkage of digitisation image and OCR output. The second case study demonstrates what becomes possible if OCR can be customised directly within a larger research infrastructure for history. In such a scenario, further semantics can be added easily to the workflow, enhancing the research browse experience significantly.
Lentivirus Nef Speciﬁcally Activates Pak2

Nef proteins from human immunodeﬁciency virus type 1 (HIV-1) and simian immunodeﬁciency virus (SIV) have been found to associate with an active cellular serine/threonine kinase designated Nef-associated kinase (Nak). The exact identity of Nak remains controversial, with two recent studies indicating that Nak may be either Pak1 or Pak2. In this study, we investigated the hypothesis that such discrepancies arise from the use of different Nef alleles or different cell types by individual investigators. We ﬁrst conﬁrm that Pak2 but not Pak1 is cleaved by caspase 3 in vitro and then demonstrate that Nak is caspase 3 sensitive, regardless of Nef allele or cell type used. We tested nef alleles from three lentiviruses (HIV-1 SF2, HIV-1 NL4-3, and SIVmac239) and used multiple cell lines of myeloid, lymphoid, and nonhematopoietic origin to evaluate the identity of Nak. We demonstrate that ectopically expressed Pak2 can substitute for Nak, while ectopically expressed Pak1 cannot. We then show that Nef speciﬁcally mediates the robust activation of ectopically expressed Pak2, directly demonstrating that Nef regulates Pak2 activity and does not merely associate with activated Pak2. We report that most of the active Pak2 is found bound to Nef, although a fraction is not. In contrast, only a small amount of Nef is found associated with Pak2. We conclude that Nak is Pak2 and that Nef speciﬁcally mediates Pak2 activation in a low-abundance complex. These results will facilitate both the elucidation of the role of Nef in pathogenesis and the development of speciﬁc inhibitors of this highly conserved function of Nef.

Tiling Layered Depth Images

We present a system for modeling and real-time rendering of solid terrains. Using results from the field of tiling, we show how a global 3D texture can be computed for a 2D terrain using a small set of Layered Depth Images. We propose a new set of Wang tiles that are shown empirically to tile the plane without apparent periodic structure. Furthmore, we introduce a new imagebased data struture: multiresolution view-dependent Layered Depth Images. As our results show, this method produces natural looking 3D textures, with full parallax, in real time.
Goals and Online Retail Success: The Small Business Perspective

Paper Abstract Goal setting theory holds that the act of strategic planning itself contributes to perceived success by identifying goals for the new strategy. Strategic planning activity and performance indicators may affect the perceived success of online strategy in small business. The study uses a survey of 179 small business retailers to find out the performance signals that most influence perceived success of an online retail strategy. The research finds that use of formal goal setting is significantly related to perceived success. The research also finds that perceived success is driven by perceived increases in customer numbers and improvements to customer service. other factors of from the small perspective have not been studied.
