description: In this paper, we report our studies on the gaseous and chemical properties of a relatively large sample (53 members) of blue compact dwarf galaxies (BCDs). The results of correlations among the oxygen abundance, stellar mass, gas mass, baryonic mass, and gas fraction are present both for E- and I-type BCDs, which are classified according to Loose & Thuan (1985) and show elliptical and irregular outer haloes, respectively. These correlations of I-type BCDs show similar slopes to those of E-type ones. However, in general, E-type BCDs are more gas-poor and metal-rich than I-type ones at a given baryonic mass. Based on these results, we suggest that E-type BCDs, at least a part of them, and I-type ones might be likely at different evolutionary phases and/or having different progenitors. Our investigation of the correlation between oxygen abundance and gas fraction shows that BCDs appear to have not evolved as isolated systems, but to have experienced some gas flows and/or mergers.

description: Somatic embryogenesis is well established for the economic relevant ornamental crop Cyclamen and thus could supplement the elaborate propagation via seeds. However, the use of somatic embryogenesis for commercial large scale propagation is still limited due to physiological disorders and asynchronous development within emerged embryos. To overcome these problems, profound knowledge of the physiological processes in Cyclamen embryogenesis is essential. Thus, the proteomes of somatic and zygotic embryos were characterised in a comparative approach. Protein separation via two dimensional IEF-SDS PAGE led to a resolution of more than 1,000 protein spots/gel. Overall, 246 proteins were of differential abundance in the two tissues compared. Mass spectrometry analysis of the 300 most abundant protein spots resulted in the identification of 247 proteins, which represent 90 distinct protein species. Fifty-five percent of the 247 proteins belong to only three physiological categories: glycolysis, protein folding and stress response. The latter physiological process was especially predominant in the somatic embryos. Remarkably, the glycolytic enzyme enolase was the protein most frequently detected and thus is supposed to play an important role in Cyclamen embryogenesis. Data are presented that indicate involvement of "small enolases" as storage proteins in Cyclamen. A digital reference map was established via a novel software tool for the web-based presentation of proteome data linked to KEGG and ExPasy protein-databases and both were made publicly available online. © 2011 Springer Science+Business Media B.V.

description: The low-energy monochromatic neutron emission from an Y-88/Be source can be exploited to mimic the few keVnr nuclear recoils expected from low-mass Weakly Interacting Massive Particles (WIMPs) and coherent scattering of neutrinos off nuclei. Using this source, a ~<10% quenching factor is measured for sodium recoils below 24 keVnr in NaI[Tl]. This is considerably smaller than the 30% typically adopted in the interpretation of the DAMA/LIBRA dark matter experiment, resulting in a marked increase of its tension with other searches, under the standard set of phenomenological assumptions. The method is illustrated for other target materials (superheated and noble liquids).

description: The mitochondrial nicotinamide adenine dinucleotide, reduced (NADH) dehydrogenase complex (complex I) of plants has a molecular mass of about 1000 kDa and is composed of more than 40 distinct protein subunits. About three quarter of these subunits are homologous to complex I subunits of heterotrophic eukaryotes, whereas the remaining subunits are unique to plants. Among them are three to five structurally related proteins that resemble an archaebacterial γ-type carbonic anhydrase (γCA). The γCA subunits are attached to the membrane arm of complex I on the matrix-exposed side and form an extra spherical domain. At the same time, they span the inner mitochondrial membrane and are essential for assembly of the protein complex. Expression of the genes encoding γCA subunits is reduced if plants are cultivated in the presence of elevated CO2 concentration. The functional role of these subunits within plant mitochondria is currently unknown but might be related to photorespiration. We propose that the complex I-integrated γCAs are involved in mitochondrial HCO3- formation to allow efficient recycling of inorganic carbon for CO2 fixation in chloroplasts under high light conditions. © Physiologia Plantarum 2007.

description: We aim at characterising dense cores in the clustered environments associated with massive star-forming regions. For this, we present an uniform analysis of VLA NH3(1,1) and (2,2) observations towards a sample of 15 massive star-forming regions, where we identify a total of 73 cores, classify them as protostellar, quiescent starless, or perturbed starless, and derive some physical properties. The average sizes and ammonia column densities are 0.06 pc and 10^15 cm^-2, respectively, with no significant differences between the starless and protostellar cores, while the linewidth and rotational temperature of quiescent starless cores are smaller, 1.0 km/s and 16 K, than those of protostellar (1.8 km/s, 21 K), and perturbed starless (1.4 km/s, 19 K) cores. Such linewidths and temperatures for these quiescent starless cores in the surroundings of massive stars are still significantly larger than the typical values measured in starless cores of low-mass star-forming regions, implying an important non-thermal component. We confirm at high angular resolutions the correlations previously found with single-dish telescopes between the linewidth, the temperature of the cores, and the bolometric luminosity. In addition, we find a correlation between the temperature of each core and the incident flux from the most massive star in the cluster, suggesting that the large temperatures measured in the starless cores of our sample could be due to heating from the nearby massive star. A simple virial equilibrium analysis seems to suggest a scenario of a self-similar, self-graviting, turbulent, virialised hierarchy of structures from clumps (0.1-10 pc) to cores (0.05 pc). A closer inspection of the dynamical state taking into account external pressure effects, reveal that relatively strong magnetic field support may be needed to stabilise the cores, or that they are unstable and thus on the verge of collapse.

description: С целью повышения  конкурентоспособности овцеводства в Узбекистане с использованием лучшего мирового генофонда выведена новая породная группа овец мясо-шерстной продуктивности – узбекские мясо-шерстные овцы. В условиях круглогодичного пастбищного содержания, на хороших естественных травах сезонных горных пастбищ в резко континентальном климате, с высокой температурой, сухим воздухом и интенсивной инсоляцией, созданы специфический “Ахангаранский” и “Паркентский” экотипы мясо-шерстных овец, а в дальнейшем породная группа мясо-шерстных овец. В 1980-1985 годах прошлого столетия поголовье  таких овец в республике  превысило  200 тыс  голов, а в настояшее  время значительно сократилось. В условиях фермерских хозяйств “Холтураев Ойбек ХМ” и “Оханг Абдуллаев Абдурауф” Ахангаранского района Ташкентской  области Республики Узбекистан ведётся научно-хозяйственный опыт. Сформированы две группы:  I группа (контрольная) – ярки местных курдючных овец (джайдара), 50 голов, II группа (опытная) – ярки мясо-шерстные узбекские, 50 голов. Местные курдючные ярки имеют более высокую живую массу, чем  мясо-шерстные сверстницы. При этом живая масса мясо-шерстных ярок на 3,8 кг (8,9%) ниже, а выход шерсти на 1,58 кг (102,6%) выше,  чем у местных курдючных. Абсолютные среднесуточные привесы от рождения до трёх месяцев жизни по двум  группам ягнят были почти одинаковые.
description: In order to increase the competitiveness of sheep breeding in Uzbekistan, using the best global gene pool, a new breed group of sheep with meat and wool productivity (Uzbek meat and wool sheep) has been bred. In conditions of year-round pasture keeping, on good natural grasses of seasonal mountain pastures in a harsh continental climate, with high temper-ature, dry air and intense insolation, specific Akhangaran and Parkent ecotypes of meat and wool sheep were created, and subsequently a pedigree group of meat and wool sheep. In the years 1980-1985 of the last century, the number of such sheep in the republic exceeded 200 thousand heads, and nowadays it is significantly reduced. In the conditions of  such farms as “Kholturaev Oybek KhM” and “Ohang Abdullaev Abdurauf” of the Akhangaran District in the Tashkent Region of the Republic of Uzbekistan, scientific and economic experience is be-ing conducted. Two groups were formed: group I (control), ewe lambs of local fat-rumped sheep (jaidara) of 50 heads, group II (experimental), Uzbek meat and wool ewe lambs, 50 heads. Local fat-rumped ewe lambs have a higher live weight than their meat and wool herd mates. At the same time, the live weight of meat and wool ewe lambs is 3,8 kg (8,9%) lower, and the yield of wool is 1,58 kg (102,6%) higher than that of the local fat-rumped sheep. Ab-solute average daily gains from birth to three months of life were almost the same for  two groups of lambs.

description: Hybrid semiconductor-based nanocrystals (NCs) are generally synthesized in organic media prior to their assembly into catalytically promising nanostructures via multistep methods. Here, a tunable, easy-to-adapt and versatile approach for the preparation of hybrid nanoparticle networks from aqueous nanocrystal solutions is demonstrated. The networks consist of interconnected semiconductor NC backbones (made of CdSe/CdS dot-in-rods or core/crown nanoplatelets) decorated with noble metal (Au and Pt) or with metal-based domains (Co2+ and Ni2+) demonstrating a powerful synthetic control over a variety of hybrid nanostructures. The deposition of the domains and the formation of the network take place simultaneously (one-step method) at room temperature in dark conditions without any external trigger. Beside the in-depth structural characterization of the gel-like hybrid networks, the wavelength-dependent optical features are studied to reveal an efficient charge carrier separation in the systems and a controllable extent of fluorescence quenching through the domain sizes. Photoluminescence quantum yields and decay dynamics highlight the importance of fine-tuning the conduction band/Fermi level offset between the semiconductors and the various deposited metals playing central role in the electron–hole separation processes. This procedure provides a novel platform toward the preparation of photo(electro)catalytically promising hybrid nanostructures (acetogels and xerogels) without the need of presynthetic hybrid particle design.

Subjects: subject: Medicine and Health Sciences

description: Vascular cognitive impairment encompasses several types of deficits, ranging from mild cognitive impairment to dementia. The cognitive reserve is the brain’s ability to balance damage and improve performance through some types of brain networks. The purpose of this systematic review was to assess the relationship between reserve in vascular impairment, looking specifically at whether cognitive decline is influenced by cognitive reserve, to identify significant vascular risk factors and their pathological pathways and to evaluate the importance of neurological rehabilitation in pa-tients with cognitive impairment. To achieve this purpose, a systematic review covering these four issues was conducted in April 2022 within the PubMed database. A total of 747 scientific articles were found and 39 papers were taken into consideration for the final analysis. We concluded that there is no consensus on the protective effects of brain reserve on cognitive decline, stroke and di-abetes can be considered important risk factors for vascular cognitive impairment while hyperten-sion is not as damaging as blood pressure variability which structurally alters the brain through a variety of mechanisms. Rehabilitation is of utter importance in the regression of cognitive decline in the context of vascular alterations.

description: We present a convergent synthetic route towards boron-nitrogen containing polycyclic aromatic hydrocarbons (BN-PAHs) that allowed us to synthesize six derivatives. Starting from the conjunction of a 1,2-azaborinine nucleophile and various aryl electrophiles, the key step was the extension of the aromatic system via an electrophilic ring closure of the respective alkyne precursors. Our route allows to circumvent the use of substituted PAH precursors, which are often unavailable. Instead, it builds up the BN-PAHs solely from easily accessible monocycles. All derivatives were emissive in solution and solid state with quantum yields up to Φlum = 0.40 and small Stokes shifts. The emission wavelengths in solid state were notably dependent on the connectivity of the rings. Due to excimer formation in one derivative, its emission was significantly redshifted with a comparatively slow secondary photoluminescence (PL) decay.

description: Plasmodium falciparum aquaglyceroporin (PfAQP) is a multifunctional channel protein in the plasma membrane of the malarial parasite that causes the most severe form of malaria infecting more than a million people a year. Finding a novel way to inhibit PfAQP, I conducted 3+ microseconds in silico experiments of an atomistic model of the PfAQP-membrane system and computed the chemical-potential profiles of six permeants (erythritol, water, glycerol, urea, ammonia, and ammonium) that can be efficiently transported across P. falciparum's plasma membrane through PfAQP's conducting pore. The profiles show that, with all the existent in vitro data being supportive, erythritol, a permeant of PfAQP itself having a deep ditch in its permeation passageway, strongly inhibits PfAQP's functions of transporting water, glycerol, urea, ammonia, and ammonium (The IC50 is in the range of high nanomolars). This suggests the possibility that erythritol, a sweetener generally considered safe, may be the drug needed to kill the malarial parasite in vivo without causing serious side effects.

Interesting Evidence for a Low-Level Oscillation Superimposed on the Local Hubble Flow

description: Historically the velocity scatter seen on local Hubble plots has been attributed to the peculiar velocities of individual galaxies. Although most galaxies also have uncertainties in their distances, when galaxies with accurate distances are used recent studies have found that these supposed peculiar velocities may have preferred, or discrete, values. Here we report the interesting result that when these discrete components are identified and removed from the radial velocities of the SNeIa galaxies studied in the Hubble Key Project, there is evidence for a residual oscillation, or ripple, superimposed on the Hubble flow. This oscillation has a wavelength near 40 Mpc and, because its amplitude is small compared to that of the scatter in velocities, it becomes visible only after the discrete components are removed. This result is interesting because even if this ripple has been produced by a selection effect, the fact that it is only revealed after the discrete velocities are removed implies that the discrete velocities are real. Alternatively, if no selection effect can be identified to explain the ripple, then both the discrete velocities and the ripple together become very difficult to explain by chance and these results could then have interesting cosmological consequences.

description: We describe a scheme that enables a strong coherent coupling between a topological qubit and the quantized motion of a magnetized nanomechanical resonator. This coupling is achieved by attaching an array of magnetic tips to a namomechanical resonator under a quantum phase controller which coherently controls the energy gap of a topological qubit. Combined with single-qubit rotations the strong coupling enables arbitrary unitary transformations on the hybrid system of topological and mechanical qubits and may pave the way for the quantum information transfer between topological and optical qubits. Numerical simulations show that quantum state transfer and entanglement distributing between the topological and mechanical qubits may be accomplished with high fidelity.

description: Context. Kinematical data such as the mean velocities and velocity dispersions of stellar samples are useful tools to study galactic structure and evolution. However, observational data are often incomplete (e.g., lacking the radial component of the motion) and may have significant observational errors. For example, the majority of faint stars observed with Gaia will not have their radial velocities measured. Aims. Our aim is to formulate and test a new maximum likelihood approach to estimating the kinematical parameters for a local stellar sample when only the transverse velocities are known (from parallaxes and proper motions). Methods. Numerical simulations using synthetically generated data as well as real data (based on the Geneva-Copenhagen survey) are used to investigate the statistical properties (bias, precision) of the method, and to compare its performance with the much simpler "projection method" described by Dehnen & Binney (1998). Results. The maximum likelihood method gives more correct estimates of the dispersion when observational errors are important, and guarantees a positive-definite dispersion matrix, which is not always obtained with the projection method. Possible extensions and improvements of the method are discussed.

description: The study looks at a Free Primary Education (FPE) program in the Western Region of Nigeriafrom in 1955 - 1965 that included building new schools, hiring teachers, and mandating that children attend primary school. The study assess whether this program could have positively impacted educational and life outcomes in western Nigerian communities as well as in eastern Beninese communities with connections to Nigeria, even if children in those communities did not themselves attend Nigerian primary schools. There is evidence that the program led to increased school attendance and primary school completion for the cohort of individuals exposed to the FPE in the former Western Region. These effects are significantly larger for females. Evidence of spillovers to neighbouring communities in Nigeria particularly for the next generation was also found. However, there is no evidence that the FPE program improved educational outcomes in indirectly treated Beninese communities for those who were of school age at the time of the FPE.

Исследования по изучению гидролитических процессов показали значительное увеличение кислотного числа при режиме хранения  2 в конце срока хранения (через 12 месяцев). Процесс перекисного окисления липидов при  режиме 2 уже после 8 месяцев хранения достиг пределов, когда продукт не подлежит реализации и является недоброкачественным. Более интенсивно при режиме 2 происходило образование вторичных продуктов окисления.
description: In the work, the processes occurring in dry enriched milk during storage under various conditions were studied: 4 ± 2 ° С (mode 1) and at 18 ± 2 ° С (mode 2). Studies on the study of hydrolytic processes have shown a significant increase in acid number during storage mode 2 at the end of the storage period (after 12 months). The process of lipid peroxidation in mode 2 after 8 months of storage has reached the limits when the product is not sold and is of poor quality. The formation of secondary oxidation products occurred more intensively under regime 2.

description: Individuals with developmental coordination disorder (DCD) experience motor skill and executive function (EF) difficulties that challenge their daily activities. This systematic review aims to provide an in-depth analysis of the relationships between motor skills and EFs in studies among individuals with DCD. We conducted a systematic search of eight electronic databases for articles (published 1994–2021) reporting on quantitative studies that estimated relationships between motor skills and EFs when assessing children, adolescents and adults with DCD. Motor skills and EFs were assessed via reliable and validated assessment tools. Two reviewers independently screened the articles. We evaluated the quality of the selected articles according to EPHPP guidelines and the methodological quality of the assessments from these studies using the COSMIN checklist and reported results following the PRISMA-P checklist. This systematic review was registered in PROSPERO (CRD42019124578). A total of 30,808 articles were screened. Eleven articles met the inclusion criteria and were reviewed. Findings from nine studies demonstrated weak to strong correlations between aspects of motor skills and EFs. Limited evidence supports the relationships between motor skills and EFs among individuals with DCD. Occupational therapists should consider the possibility of this relationship and give more consideration to these components when planning intervention for individuals with DCD.

description: We study the collapse of a fuzzy sphere, that is a spherical membrane built out of D0-branes, in the BFSS model. At weak coupling, as the sphere shrinks, open strings are produced. If the initial radius is large then open string production is not important and the sphere behaves classically. At intermediate initial radius the back-reaction from open string production is important but the fuzzy sphere retains its identity. At small initial radius the sphere collapses to form a black hole. The crossover between the later two regimes is smooth and occurs at the correspondence point of Horowitz and Polchinski.

description: Lithium-sulfur (Li-S) batteries have attracted widespread attention due to their high theoretical energy density. However, their practical application is still hindered by the shuttle effect and the sluggish conversion of lithium polysulfides (LiPSs). Herein, monodisperse molybdenum (Mo) nanoparticles embedded onto nitrogen-doped graphene (Mo@N-G) were developed and used as a highly efficient electrocatalyst to enhance LiPS conversion. The weight ratio of the electrocatalyst in the catalyst/sulfur cathode is only 9%. The unfilled d orbitals of oxidized Mo can attract the electrons of LiPS anions and form Mo–S bonds during the electrochemical process, thus facilitating fast conversion of LiPSs. Li-S batteries based on the Mo@N-G/S cathode can exhibit excellent rate performance, large capacity, and superior cycling stability. Moreover, Mo@N-G also plays an important role in room-temperature quasi-solid-state Li-S batteries. These interesting findings suggest the great potential of Mo nanoparticles in building high-performance Li-S batteries.

description: Dispersal is a key process in ecology and evolutionary biology, as it shapes biodiversity patterns over space and time. Mounting evidence is showing that attitude to disperse is unevenly distributed among individuals within animal populations, and that individual personality can have pivotal roles in the shaping of this attitude. Here, we contribute to the study of the genetic underpinnings of dispersal-related behavioral variation by assembling and annotating the first de novo transcriptome of the head tissues of Salamandra salamandra. Although dispersal occurs mostly during the post-metamorphic terrestrial life stage in this species, variation in dispersal-related personality traits is already evident at the aquatic larval stage, making it an excellent candidate species for studies of carry-over effects. We employed a structured pipeline to de-novo assemble and annotate transcripts from RNA-Seq in a set of individuals representative of distinct behavioral profiles. We obtained 1,153,432,918 reads, which were successfully de novo assembled and annotated. The high-quality assembly was confirmed by comparing BUSCO, DETONATE and TransRate with the S. salamandra dataset. By aligning the contigs against the de novo transcriptome we obtained a percentage of mapping higher than 94%. The homology annotation performed with DIAMOND led to 153,048 (blastx) and 95,942 (blastp) shared contigs, annotated on NCBI nr, Swiss-Prot and TrEMBL. The domain and site protein prediction made with InterProScan led to 9850 GO-annotated contigs. This de-novo transcriptome represents reliable reference for whole transcriptome and proteome studies of other amphibians, for designing primers to clone specific genes or monitor their expression, and for analyzing comparative gene expression profiles between alternative behavioral types.

description: To enable data aggregation among the event sources in wireless sensor networks and to reduce the communication cost there is a need to establish a coveraged tree structure inside any given event region to allow data reports to be aggregated at a single processing point prior to transmission to the network. In this paper we propose a novel technique to create one such tree which maximizes the lifetime of the event sources while they are constantly transmitting for data aggregation. We use the term Centralized Lifetime Maximizing Tree (CLMT) to denote this tree. CLMT features with identification of bottleneck node among the given set of nodes. This node collects the data from every other node via routes with the highest branch energy subject to condition loop is not created. By constructing tree in such a way, protocol is able to reduce the frequency of tree reconstruction, minimize the delay and maximize the functional lifetime of source nodes by minimizing the additional energy involved in tree reconstruction.

description: In der vorliegenden Dissertation wurde folgende Forschungsfrage untersucht: Wie legitimieren Wissenschaftsbehörden innerhalb der Risikoregulierung ihr Handeln? Dabei wurden Wissenschaftsbehörden als Teil der Ressortforschungseinrichtungen definiert, der mit der Bereitstellung von wissenschaftlichem Wissen zur politischen Entscheidungsfindung, bei der Reduzierung zivilisatorischer Risiken, beiträgt. Da Wissenschaftsbehörden jedoch einem demokratischen Legitimationsdefizit unterliegen und sich gleichzeitig in einem wissenschaftlichen Dilemma bewegen (zwingende Empfehlungen im Raum wissenschaftlicher Unsicherheiten), müssen sie ihr Handeln legitimieren. Anhand einer Mehrfallstudie besonders einflussreicher Fälle (Endlagersuche, Fracking, Glyphosat) wurde entlang von vier Dimensionen (Standardisierung, Autonomisierung, Verwissenschaftlichung und Steigerung der Transparenz) mittels sechs Expert:inneninterviews in verschiedenen Behörden (Bundesanstalt für Risikobewertung, Bundesanstalt für Geowissenschaften und Rohstoffe) sowie einer umfassenden rekonstruktiven Dokumentenanalyse Veränderungen in den Behörden untersuchen.

description: Bases of exactly localized Minkowski and Rindler states on spacelike hypersurfaces are used to describe inertial and accelerated photon counting devices. It is found that the spacetime coordinates of photons absorbed by a pair of counteraccelerating detectors in causally disconnected Rindler wedges are correlated. If a photon is absorbed by a single accelerated detector the Minkowski vacuum collapses to a state containing at least one photon and that photon can be absorbed by an inertial detector.

description: Quantitative evidence on education system coherence is limited, but research suggests that alignment of instructional components is crucial for children's learning. The study uses the Surveys of Enacted Curriculum methodology to investigate the alignment of instructional components in Nigeria's primary education system. The analysis focuses on curriculum standards, national exams, and classroom instruction for mathematics and English language across all primary grades. The study reveals that key foundational skills are covered by all three components, but there are omissions in the English language exams. The components place high emphasis on low cognitive demand processes and low emphasis on more demanding cognitive processes. The curriculum standards and classroom instruction show a slow pace of content progression across grades. Despite the high alignment, low student performance in exams suggests that the education system may be operating in a low-achieving equilibrium.
