description: In a series of papers, we have investigated the compatibility of the $Kimber$-$Martin$-$Ryskin$ ($KMR$) and $Martin$-$Ryskin$-$Watt$ ($MRW$) $unintegrated$ parton distribution functions ($UPDF$) as well as the description of the experimental data on the proton structure functions. The present work is a sequel to that survey, via calculation of the transverse momentum distribution of the electro-weak gauge vector bosons in the $k_t$-factorization scheme, by the means of the $KMR$, the $LO\;MRW$ and the $NLO\;MRW$ $UPDF$, in the next-to leading order ($NLO$). To this end, we have calculated and aggregated the invariant amplitudes of the corresponding $involved$ diagrams in the $NLO$, and counted the individual contributions in different frameworks. The preparation process for the $UPDF$ utilizes the $PDF$ of $Martin$ et al, $MSTW2008-LO$, $MSTW2008-NLO$, $MMHT2014-LO$ and $MMHT2014-NLO$ as the inputs. Afterwards, the results have been analyzed against each other, as well as the existing experimental data. Our calculation show excellent agreement with the experiment data. It is however interesting to point-out that, the calculation using the $KMR$ framework illustrates a stronger agreement with the experimental data, despite the fact that the $LO\;MRW$ and the $NLO\;MRW$ formalisms employ a better theoretical description of the $DGLAP$ evolution equation. This is of course due to the use of the different implementation of the angular ordering constraint in the $KMR$ approach, in which automatically includes the re-summation of $ln({1/x})$, $BFKL$ logarithms, in the $LO$-$DGLAP$ evolution equation.

description: Abstract The case study evaluated the changes brought about by the implementation of the large lecture-small recitation class mode in the delivery of an introductory speech communication course in terms of 1) syllabus; 2) teaching strategies; 3) teacher-student interaction; 4) the effectiveness of current teaching strategies in achieving said course objectives and 5) teachers concerns regarding the mode. Six Speech Communication 1 (SPCM 1) large lecture class teachers of the University of the Philippines Los Baños (UPLB) and 716 students were surveyed and/or interview during the 2nd Semester 2014-2015. Results showed that the syllabus content remained unchanged. Large class teachers cited dissatisfaction with the synchronized, time-bound schedule and large student number that constricted the use of different teaching strategies and minimized teacher-student interaction. They used a wide variety of group dynamics and interactive teaching strategies in the generally expository nature of their lecture classes. Students’ perceptions of their lecture teachers as influential and friendly leaders were found higher compared to their teachers’ self. Students’ responses towards the large class mode were generally positive with only a few students calling for policy recall. Nonetheless, the SPCM 1 teachers remained concerned about the effectiveness of the large class mode in achieving the course objectives. The study concluded that the SPCM 1 large class mode has been received positively by the students and has worked because of the concerned teachers’ personal efforts despite persistent beliefs that small classes are the best approach to delivering a communication course. The study recommended significant institutional measures, incentives, and continuous professional faculty and staff development and mentoring programs on large class teaching and other educational changes.

description: We study parallel algorithms for addition of numbers having finite representation in a positional numeration system defined by a base $β$ in $\mathbb{C}$ and a finite digit set $\mathcal{A}$ of contiguous integers containing $0$. For a fixed base $β$, we focus on the question of the size of the alphabet allowing to perform addition in constant time independently of the length of representation of the summands. We produce lower bounds on the size of such alphabet $\mathcal{A}$. For several types of well studied bases (negative integer, complex numbers $ -1 + \imath$, $2 \imath$, and $\imath \sqrt{2}$, quadratic Pisot unit, and the non-integer rational base), we give explicit parallel algorithms performing addition in constant time. Moreover we show that digit sets used by these algorithms are the smallest possible.

description: A new oleanane-type triterpene, ardisiapunine A (1), together with eight known compounds were isolated from the roots of Ardisia lindleyana D.Dietr. Their chemical structures were determined by means of spectroscopic methods including HR-ESI-MS and (1 D, 2 D) NMR data. The absolute configuration of compound 1 was established by a single-crystal X-ray diffraction experiment. The new compound is an unusual oleanane-type triterpene bearing an acetal and a C-13—C-18 double bond. The cytotoxicity of all isolated compounds were evaluated using four human cancer cell lines, including A549, HepG2, HeLa and U87. The new compound 1 and compound 2 were weakly active but the known compound 6 exhibited a high cytotoxicity compared to cisplatin.
The Formation of A 'Filipina Feminism': Re- imagining Filipina Women's Movements in Conversations with Gabriela over Time

subject: Women's Movements
subject: Southern Asia Studies

description: The women's movement in the Philippines is the product of a long history of struggle and participation in various historical conjunctures. As a nation troubled by a difficult colonial past, it is important to locate the role of women in the quest for independence. As a society characterized by unequal power relations between the masses and the ruling class, it is crucial to place the women's movement in the struggle for democracy, equality, and social justice. As part and parcel of the whole array of social movements in the Philippines, the women's movement developed and responded to the needs of the time. The changes in the nature of the women's movement from one historical period to another were apt responses to the social conditions and to the status of their struggle at different points in the past. Thus, this study explores the history and experiences of Filipina women in Gabriela, the largest women’s organization in the Philippines, as they build solidarity and shape women’s history over time and across the nation. This paper focuses on Gabriela’s shifting gender politics in different political terrains and remakes Filipina feminisms in dialogue with Western Feminism. We use Gabriela’s story as a case study to investigate the ways that internal fragmentation and constantly negotiated feminist agendas have affected the remaking of feminism. This paper observes the internal dynamics within women’s organizing through a processual lens, allowing us to join voices that unsettle false assumptions around Third World women's experiences and status. The stories we unveil in this study stress the importance of examining the grounded experiences of women's organizing with non-teleological assumptions. The conclusions we draw from the case study urges us to understand 'Filipina feminism' in its unique positionality which was influenced by anti- imperialism, nationalism, and centered around precarity and multiple temporalities.

description: In the present study, we report herein the isolation of cadinane-type sesquiterpenoid, tatarinowin A (ACH-6), and pentadecanoic acid (ACH-8) from petroleum ether extract of rhizome of Acorus calamus L. (Acoraceae) along with 6 other known compounds in this species. It is pertinent to mention here that this is the first report to stain these compounds in which dereplication approach based on GC-MS was applied to target unknown compounds ACH-6 and ACH-8 in A. calamus L. Derelpication approaches based on GC-MS is very useful technique in the area of drug discovery and have eminence potential to identify known and unknown compounds present in extracts of medicinal important plants. This technique can be used to expedite the process of purification of unknown compounds from different matrixes. The isolated compounds were identified with the help of inbuilt library search which reveals the presence of 17 known and 4 unknown compounds. Further, the structure elucidation of all isolated compounds was done using spectroscopy techniques. Also, the structure of ACH-6 was further confirmed by using the single-crystal X-ray diffraction technique.

description: Neutrino oscillations are one of the most studied and successful phenomena since the establishment of the solar neutrino problem in late 1960's. In this work we discuss the exact expressions for the probability P_{αβ} in a constant density medium, in terms of the standard vacuum parameters and the medium density. Besides of being compact, these expressions are independent of any particular parametrization, which could be helpful in the application of unitary tests of the mixing matrix. In addition, we introduce a new approximation on P_{αβ} and compare it with the most commonly used, discussing their main differences.

A study of Key Stage 3 music teachers’ pedagogic beliefs in the context of a new curriculum for Wales
Creators: name: Breeze, Tom
Publisher: name: Cardiff Metropolitan University
Year: 2023
Subjects: Creative arts, media and communication curriculum and pedagogy

description: This study conceptualises the pedagogic beliefs of music teachers (n=75) working with 11-14 year-olds (the age range within which music is a compulsory subject) in mainstream secondary schools in Wales. It uses a mixed-methods, qualitative-dominant approach, with data gained from in-depth interview and online survey. The resulting model sheds light on music teachers’ views of learning as a complex, cyclic process in which the aim is to allow pupils artistic agency, but in which the reality can be muddied by contradiction: what one teacher described as ‘the illusion of choice’. Teachers’ desired outcomes for the learning process are defined as ‘pedagogic’ or ‘pragmatic’, and these desired outcomes challenge prevailing opinions in the literature about a potential culture of elitism in the music classroom. However, in the context of increased uncertainties stemming from the introduction of a new curriculum, music teachers in Wales need to take care not to fall back on ‘soft’ justifications for the existence of the subject based on being ‘good for’ pupils or generating transferable creative dispositions.

description: Biomolecules are complex systems stabilized by a delicate balance of weak interactions, making it important to assess all energetic contributions in an accurate manner. However, it is a priori unclear which contributions make more of an impact. Here, we examine stacked polyglutamine (polyQ) strands, a peptide repeat often found in amyloid aggregates. We investigate the role of hydrogen bond (HB) cooperativity, van der Waals (vdW) dispersion interactions, and quantum contributions to free energies, including anharmonicities through density functional theory and ab initio path integral simulations. Of these various factors, we find that the largest impact on structural stabilization comes from vdW interactions. HB cooperativity is the second largest contribution as the size of the stacked chain grows. Competing nuclear quantum effects make the net quantum contribution small but very sensitive to anharmonicities, vdW, and the number of HBs. Our results suggest that a reliable treatment of these systems can only be attained by considering all of these components.

description: Earth Observation (EO) applications enable decision-makers, researchers, and specialists to understand the phenomena of our planet, allowing global changes to be made from local actions taken by the public and private sectors. With the dissemination and use of Open Data practices, the EO applications have been enhanced, allowing numerous works to be developed, ranging from the analysis of anthropic actions on inland waters to the temporal analysis of land use and land cover changes. These advances and improvements in EO applications have made their development complex, requiring several materials to be used together with the data to compose the results. Consequently, organizing, sharing, and preserving these applications and the knowledge within them to enable reproduction and replication has become a challenge. Often these activities require specific expertise from researchers and specialists and technical infrastructure.
The Group on Earth Observations (GEO) and its community promote Open Data practices, being responsible for defining guidelines and developing the Global Earth Observation System of Systems (GEOSS) that enhances access to EO data. Recently, GEO started the development of a new component of the GEOSS ecosystem, the GEO Knowledge Hub (GKH), to foster the reproduction and replication of EO applications. Created based on the GEO Data Sharing Principles and the GEO Data Management Principles, the GKH allows users to share their EO applications and the underlying resources (e.g., processing scripts, datasets, and description notes), enabling people to understand, reproduce and replicate the shared EO application. In the GKH, the resources of an application can have files (e.g., satellite imagery datasets, in-situ data files) and metadata (e.g., title, authors, spatial location). Furthermore, each resource can be associated with an individual persistent identifier (DOI) created by the GKH, enhancing dissemination and citation.
Applications shared on the GKH can be found and used, making their knowledge accessible. For this, the GKH provides high-level features for organizing the application materials and facilitating their sharing. In addition, the GKH has a powerful search engine that enables textual, thematic (e.g., Sustainable Development Goal-oriented search), and spatial-temporal searches. In addition to share and search capabilities, the GKH provides features that facilitate community engagement, such as discussion sections (Real-time Q&A) and a feedback system. All these features are accessible through high-level web interfaces and Rest APIs, allowing the integration of various tools to use the digital repository.
To encourage the use of the GEO Knowledge Hub, the GEO Secretariat and the GEO community create webinars presenting the digital library and its forms of use. This Knowledge Package centralizes the materials produced in each of these webinars.

description: The appraisal of metallic materials requires application of advanced characterisation techniques. In this paper, the use has been made of Scanning Electron Microscopy, Transmission Electron Microscopy, X-ray diffraction (XRD) and Energy Dispersive X-ray Spectroscopy techniques to characterise morphological, structural and chemical composition of 316-stainless steel and unknown brass sample. The determined lattice parameter of unknown brass sample was 3.6812A and consisted of 63% Cu and 37% Zn by weight. The XRD analysis indicated a faced-centred-cubic crystal structure and the sample concluded to be an alpha brass. The measured dislocation density in 316-stainless steel increased with increasing plastic strain and the dislocation structures varied from relatively uniform distribution at low strains to cell-like structures at high strains. The spread of X-ray diffraction peak related linearly with the dislocation content of 316-stainless steel.

description: Pyrus communis L. (cv. Le-Conte) (pears) and Malus domestica Borkh. (cv. Anna) (apples) are economic fruit crops cultivated in Egypt. Their leaves were assessed for their beta-sitosterol content and found to have 9.4 mg/g dried leaves wt and 5 mg/g dried leaves, respectively. So we used the lipoidal leaves extracts in the formulation of eight beta-sitosterol-rich emulgels from which the most stable formulae were tested for their antimicrobial activity. Finally, the formulae which exerted antimicrobial activity were biologically evaluated for wound healing against well-known wound healing ointment Mebo® which is composed mainly of 0.25% beta-sitosterol in a base of sesame oil and beeswax. Wound contraction was statistically different in both formulae F3 and F8 from both control and Mebo® groups which indicated better wound healing activity of these formulae ensured by further histopathological study of the healed wounds.

description: Phytochemical investigation of the flowers of Anomianthus dulcis led to the isolation of eleven known compounds. The isolated compounds were identified by analysis of physical and spectroscopic (IR, 1 D and 2 D NMR) data. We report five flavonoids (1–4 and 10), two chalcone-sesquiterpenoids (5 and 6), one indole alkaloid (7), one triterpenoid (8), and a mixture of two phenolic compounds (9 and 11). Remarkably, it is the second isolation of sumadain A (5) and sumadain B (6) from a natural source. Compounds 5 and 6 were evaluated against several cancer cell lines, as the previous report lacked biological activity studies. Compound 6 showed strong cytotoxicity against Hela, HT-29, HCT-116, and A549 cell lines, with IC50 values in the range of 5.43–14.64 µg/mL.

description: We report a systematic angle-resolved photoemission spectroscopy on topological insulator (TI) TlBi1-xSbxTe2 which is bulk insulating at 0.5 < x < 0.9 and undergoes a metal-insulator-metal transition with the Sb content x. We found that this transition is characterized by a systematic hole doping with increasing x, which results in the Fermi-level crossings of the bulk conduction and valence bands at x~ 0 and x~1, respectively. The Dirac point of the topological surface state is gradually isolated from the valence-band edge, accompanied by a sign reversal of Dirac carriers. We also found that the Dirac velocity is the largest among known solid-solution TI systems. The TlBi1-xSbxTe2 system thus provides an excellent platform for Dirac-cone engineering and device applications of TIs.

description: Seseli is a large genus of aromatic and economically important herbs of the Apiaceae family that includes eighty-seven taxa, mainly distributed in Europe and Asia. Several species of this genus are extensively used in various popular medicines and based on their traditional uses, much research concerning biological activities have been carried out. In the present study, the chemical composition of the essential oil from aerial parts of Seseli bocconei Guss., a rare plant endemic of Sicily, was analysed by GC-MS. No one report has been previously published on the essential oil of this species. The result showed the presence of large quantity of monoterpene and sesquiterpene hydrocarbons whereas it was practically devoid of oxygenated terpenes. Main metabolites of the oil were germacrene D (18.48%) and sabinene (17.46%). Chemotaxonomic considerations with respect to other oils of Seseli taxa were carried out.

description: В работе проведён анализ данных, позволяющий составить представление о возможных механизмах процессов плазменного разложения фенола в его водных растворах под действием различных типов разряда в различных плазмообразующих газах. Обнаружено, что качественный состав частиц, способных окислять фенол, и продуктов разложения один и тот же, и не зависит от исходного плазмообразующего газа и типа разряда. Основными реагентами, приводящими к окислительной деструкции фенола, являются радикалы •ОН и атомы кислорода. В плазме воздуха появляются также оксиды азота и озон, а в плазме кислорода озон. Приводятся данные о кинетике разложения фенола (константах скоростей) в разрядах различного типа и разных плазмообразующих газах, а также об основных продуктах, образующихся при разложении. Показано, что кинетика разложения фенола во всех случаях подчиняется уравнению псевдо первого кинетического порядка по концентрации фенола. Определены показатели энергетической эффективности действия различных разрядов. В случае разряда атмосферного давления в контакте с раствором наблюдается прямая зависимость между изменением рН раствора и его проводимостью.An analysis of the data has been carried out, which allows one to gain an idea of the possible mechanisms of the plasma decomposition of phenol in its aqueous solutions under the action of various types of discharge in various plasma-forming gases. It was found that the qualitative composition of particles capable of oxidizing phenol and the decomposition products is the same and does not depend on the initial plasma-forming gas and the type of discharge. The main reagents leading to the oxidative destruction of phenol are •OH radicals and oxygen atoms. Nitrogen oxides and ozone also appear in air plasma, and ozone in oxygen plasma. Data are presented on the kinetics of phenol decomposition (rate constants) in discharges of various types and different plasma-forming gases, as well as on the main products formed during decomposition. It was shown that the kinetics of phenol decomposition in all cases obeys the pseudo first kinetic equation on phenol concentration. The energy efficiency indicators of the action of various discharges are determined. In the case of a discharge of atmospheric pressure in contact with the solution, a direct relationship is observed between the change in the pH of the solution and its conductivity.

description: Two previously undescribed compounds, namely dalpulapans F and G (1 and 2), along with 11 known compounds were isolated from the MeOH crude extract of the roots of Dalbergia stipulacea. Dalpulapan F was found as a rare isoflavone-quinone derivative. Their structures and absolute configurations were supported by extensive spectroscopic data analysis, including 1 D and 2 D NMR, HRESIMS data, specific rotation data, and comparison of the experimental and calculated ECD data. Cytotoxicity evaluation of the isolated compounds against HepG2 and KKU-M156 cell lines revealed that isoflavonoid 9 and rotenoid 13 exhibited the most activity against the two cell lines.

description: В работе представлены практические сравнительные свойства антимикробной активности ряда синтезированных полимеров и сополимеров на основе стирола и акрилонитрила, а также их металло-сополимеров, полученных механическим смешением антимикробных присадок и полимеров, самих полимеров и сополимеров, без добавок, по стойкости к грибкам и бактериям. Показано их активное действие как к грибкам, так и бактериям. Установлено, что активность металло-сополимеров стирола, акрилонитрила и бутадиена проявляют большую антимикробную активности как к грибкам, так и бактериям. Данное исследование особенно важно и перспективно, поскольку решение вопроса защиты от микроорганизмов на земном шаре, в настоящее время особенно актуально.The paper presents the practical comparative properties of the antimicrobial activity of a number of synthesized polymers and copolymers based on styrene and acrylonitrile, as well as their metal copolymers obtained by mechanical mixing of antimicrobial additives and polymers, polymers and copolymers themselves, without additives, and are resistant to fungi and bacteria. Their active effect on both fungi and bacteria is shown. It has been established that the activity of the metal copolymers of styrene, acrylonitrile and butadiene exhibit great antimicrobial activity against both fungi and bacteria. This study is especially important and promising, since the solution to the issue of protection against microorganisms on the globe is currently especially relevant.

description: The demand for building material is ever increasing owing to population growth. Compacted clay bricks are an important integral building material especially for low cost durable and affordable housing segment. This is a valued building material since its properties can be modified to suit various loading conditions. In this paper, the mechanical and physical properties of clay bricks modified with varying proportions of sawdust and polystyrene are determined. Increment of non-clay material proportion in the modified-clay bricks increases their porosity and water absorbency while their bulk densities, compressive and flexural strengths decreases. The use is made of Particle Image Velocimetry (PIV) method to assess the surface deformation behavior of the modified-clay bricks under uniaxial compressive loading. The distribution of surface deformation as assessed through PIV method is relatively uniform in pure-clay bricks while modified-clay bricks indicates a non-uniform deformation localized near the loading point at low strains. The strain distribution progressively spread out in the modifiedclay brick as the failure point is approached.

description: In this work, the chemical composition and the antioxidant evaluation of the inflorescences from 12 Cannabis sativa L. monoecious cultivars (Carmagnola Lemon CL, Ferimon F, Gran Sasso Kush GSK, Antal A, Carmagnola C, Kompolti K, Futura 75 F75, Villanova V, Tiborzallasi T, Finola FL, Kc Virtus KV and Pineapple P) cultivated at the same condition, were investigated. GC-MS analysis was carried out to evaluate the volatile fraction, while HPLC-MS/MS was used for cannabinoids and polyphenolic compounds. The evaluation of antioxidant activity was carried out using ABTS*+, Trolox equivalence antioxidant capacity (TEAC), ferric reducing antioxidant property (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH*) assays in vitro. The obtained data, demonstrated that each cultivar has a characteristic chemical profile, with highest antioxidant capacity for CL, F75, GSK and F. Based on the in vitro antioxidant activity the plant extracts can be considered as promising candidates for different applications in food field.

description: The chemical investigation of the leaf extract of a Cameroonian medicinal plant, Lippia rugosa A Chev (Verbenaceae) led to the isolation of a new flavonoid derivative flavolippia (1), alongside eleven known compounds: 2,4-dimethylpyridin-3,5-diol (2), 5-hydroxy-6,7,4’-trimethoxylflavone (3), 5-hydroxy-3,7,4’-trimethoxyflavone (4), 7-hydroxy-5,6,4’-trimethoxyflavone (5), 3β-hydroxy-urs-12-en-3-ol (α-amyrin) (6), lupeol acetate (7), lup-20(29)-en-3β-ol (lupeol) (8), lup-20(29)-en-3β,28-diol (betulin) (9), fridelan-3-one (fridelan) (10), saccharose (11), cosanol (12). In addition, a new semi-synthetic alkaloid derivative named lippiamicin (13) was prepared from 2,4-dimethylpyridin-3,5-diol (2). Their structures were established on the basis of their spectroscopic data, as well as 1 D and 2 D NMR. Compounds 1-13 were evaluated for their antioxidant activities. The results obtained showed that compounds 2 and 12 were the most active with IC50 values of 0.145 ± 0.011 and 0.195 ± 0.017 µM/mL respectively (for DPPH•) and 0.241 ± 0.027 and 0.223 ± 0.024 µM/mL respectively (for FRAP) compared to butylated hydroxyltoluene used as positive control.

description: We consider a continuous-space and continuous-time diffusion process under resetting with memory. A particle resets to a position chosen from its trajectory in the past according to a memory kernel. Depending on the form of the memory kernel, we show analytically how different asymptotic behaviours of the variance of the particle position emerge at long times. These range from standard diffusive ($σ^2 \sim t$) all the way to anomalous ultraslow growth $σ^2 \sim \ln \ln t$.
