description: This study aims to show the effects of fructose on human health with approach animal sample
research. Interest is based on the due to problems of excess sugar consumption, especially the type of
fructose that many peoples don’t know realize it. This objective is supported by the data world sugar
consumption is constantly increasing. Consumption of fructose over the normal limit will increase the risk
of disease. The focus of this research parameter are the blood glucose levels and uric acid. This study design
was Randomized Post Test Control Group Design uses the subject of male white rats Rattus norvegicus (n =
39). The research subjects were then divided into three groups. The control group K (n = 13) was
administered 1 cc of distilled water, the low dose group P1 (n = 13) was given a solution of fructose 1 cc at
a dose of 450 mg/150grBW/day and the high dose group of P2 (n = 13) was given a solution of fructose 1.5
cc at a dose of 1350 mg/ 150grBW/day. Treatment of the subjects during for 30 days. Test results on blood
glucose levels an increase of 46% (P <0.05) in the high-dose nor in uric acid levels also increased 48% in the
high dose (P <0.05). Observation on fructose-containing food products have not been found labels to the
inclusion of fructose contained heavy detail. The conclusion from this research that consumption of fructose
at high levels can harm health risk giving. To anticipate the necessary arrangements total amount of
consumption of sugar, especially fructose and regulations in order to do innovation will labeling fructose
in food and beverage products. Labeling would be beneficial for consumers because they can regulate the

description: In commutative algebra, a Weitzenböck derivation is a nonzero triangular linear derivation of the polynomial algebra $K[x_1,...,x_m]$ in several variables over a field $K$ of characteristic 0. The classical theorem of Weitzenböck states that the algebra of constants is finitely generated. (This algebra coincides with the algebra of invariants of a single unipotent transformation.) In this paper we study the problem of finite generation of the algebras of constants of triangular linear derivations of finitely generated (not necessarily commutative or associative) algebras over $K$ assuming that the algebras are free in some sense (in most of the cases relatively free algebras in varieties of associative or Lie algebras). In this case the algebra of constants also coincides with the algebra of invariants of some unipotent transformation. \par The main results are the following: 1. We show that the subalgebra of constants of a factor algebra can be lifted to the subalgebra of constants. 2. For all varieties of associative algebras which are not nilpotent in Lie sense the subalgebras of constants of the relatively free algebras of rank $\geq 2$ are not finitely generated. 3. We describe the generators of the subalgebra of constants for all factor algebras $K< x,y>/I$ modulo a $GL_2(K)$-invariant ideal $I$. 4. Applying known results from commutative algebra, we construct classes of automorphisms of the algebra generated by two generic $2\times 2$ matrices. We obtain also some partial results on relatively free Lie algebras.

description: In this paper, results from a study on the use of improved coffee production technology schemes among smallholder coffee producers in three prominent coffee producing regions in Honduras are presented. The impact of various schemes (trajectories) in which different agents influence the producers’ decision to use new technologies was analyzed. In particular, there are differences in the influence of a) private coffee buying organizations and b) government and public development agencies on the innovation behavior of coffee growers. Drawing from network data that depict the internal and outbound connectedness of producers in three village communities in main coffee producing zones in Honduras, tools of social network analysis were applied to find out how interactions with certain agents, separately and cumulatively, has influenced their use of improved methods in coffee production and marketing. The results suggest that there are significant differences in the way that various providers of knowledge and technology, especially private buyers and development agencies, influence the farmers’ behavior towards innovation. The influence of buyers, according to the data, is focused on certification and quality aspects, whereas development agents focus on improved agronomic practices. Farmers who communicate with the extension branch of input providers tend to be more innovative. These results suggest that development programs should take more seriously into account the role of private actors in innovation among agricultural producers and, hence, design development programs in such a way to allow for collaboration with these agents.

description: Several researches evaluated consumers’ Willingness To Pay (WTP) for each meat traceable attribute, generating a great deal of information in this regard, although specific to the conditions of each study. In light of this, WTP estimates for traceability characteristics differ across the literature, leading sometimes to contrasting interpretations. Seeking a full, meaningful statistical description of the findings of a collection of studies, the meta-analysis allows us to analyze consistency across studies and control for factors thought to drive variations in WTP estimates. The meta-analysis has been conducted using 23 studies that, in aggregate, report 88 valuations for WTP. Our results, aside from releasing unconditional information on the WTP for single meat traceable attributes, show how certain study-specific characteristics, like the base price and the country where the study has been conducted, have a significant impact on WTP estimates
Radial Variation of Optical and Near-Infrared Colours in Luminous Early-Type Galaxies in ABELL 2199

description: We performed K band surface photometry for luminous early-type galaxies in a nearby rich cluster ABELL 2199. Combining it with B and R band surface photometry, radial variations of B-R and R-K colours in the galaxies were investigated. It is found that the inner regions of the galaxies are redder in both of B-R and R-K colours. Comparing the radial variations of both of the colours with predictions of Simple Stellar Population (SSP) models for a range of ages and metallicities, it is suggested that the cluster ellipticals have negative metallicity gradients but their age gradients are consistent with zero, although our sample is small; the typical metallicity gradient is estimated to be -0.16+- 0.09 in dlogZ/dlogr, while the age gradient is estimated to be -0.10 +- 0.14 in dlog(age)/dlogr. Considering that similar results have also been derived in the other recent studies using samples of ellipticals in the Coma cluster and less dense environments, it seems that there is no strong dependence on galaxy environment in radial gradient of stellar population in elliptical galaxy.

description: Never before has food been as safe and secure as it is today, but simultaneously, society has become increasingly critical towards agricultural and food related issues. This two-sided development between society and agribusiness will be analyzed using Framing Theory. A quantitative semantic analysis was applied to evaluate the web-based social media in Germany. 50,931 web posts were collected covering 21 issues identified as relevant for the agri-food sector. The results show that all contentious issues are mainly framed in a two-sided way. The modern productivity-driven industry is judged as a negative development, trends returning to a more natural food production are seen as positive.

description: Socotradelphys gen. nov.
Diagnosis. Body maggot-shaped, consisting of unsegmentedprosomeandvestigialurosome.Bodysurface ornamented with sparsely scattered, minute spinules. Urosome unsegmented, positioned posterodorsally on prosome, bilobed posteriorly, with deep posteromedial incision. Caudal rami lobate, lacking caudal setae. Cephalosome with large, bulbous ventrolateral processes positioned in same plane as labrum.Antenna rudimentary, but segmented and tipped with claw; positioned between bases of labrum and ventrolateral process. Labrum large, conical. Mouthparts absent. Leg 1 as globular lobe, located posterior to labrum. Legs 2–5 absent.
Type species. Socotradelphys unipedata gen. et sp. nov. by original designation.
Etymology. The generic name Socotradelphys is derived from “ Socotra Island ”, Yemen, the type locality of thetype species, and - delphys. Gender feminine.
Remarks. Boxshall & Marchenkov (2007) analysed the phylogenetic relationships between five highly transformed genera within the Notodelphyidae and referred to them as the Brementia -group. These genera are Brementia Chatton & Harant, 1915, Achelidelphys Lafargue & Laubier, 1977, Anoplodelphys Lafargue & Laubier, 1978, Paranoplodelphys Boxshall & Marchenkov, 2007, and Pholeterides. Socotradelphys gen. nov. certainly belongs to this group and is characterised by its extremely simplified body structure. It lacks the rostrum, antennules, mouthparts, and legs 2–4. Within the group, Socotradelphys gen. nov. appears to be more closely related to Anoplodelphys than to the other genera, because it carries a pair of ventrolateral processes on the cephalosome. However, all known speciesof Anoplodelphys have a rostrum and paired antennules, plus at least two pairs of biramous legs (legs 1 and 2) so the lack of a rostrum and antennules, and the possession of a uniramous leg 1 only, serves to distinguish the new genus from Anoplodelphys.

description: Africa has inherited highly arbitrary political borders that vastly complicate current efforts to accelerate agricultural growth and reduce hunger. Because Africa’s inherited political borders arbitrarily partition agro-ecological zones and natural market sheds, current country borders serve as barriers, hampering agricultural technology transfer, hindering agricultural trade and dampening incentives for farmers and agribusinesses to invest in Africa’s many regional breadbasket zones. Feasible solutions revolve around neutralizing these deleterious effects through regional scientific networks and regional corridor development programs.
Conformally symmetric vacuum solutions of the gravitational field equations in the brane-world models

description: A class of exact solutions of the gravitational field equations in the vacuum on the brane are obtained by assuming the existence of a conformal Killing vector field, with non-static and non-central symmetry. In this case the general solution of the field equations can be obtained in a parametric form in terms of the Bessel functions. The behavior of the basic physical parameters describing the non-local effects generated by the gravitational field of the bulk (dark radiation and dark pressure) is also considered in detail, and the equation of state satisfied at infinity by these quantities is derived. As a physical application of the obtained solutions we consider the behavior of the angular velocity of a test particle moving in a stable circular orbit. The tangential velocity of the particle is a monotonically increasing function of the radial distance and, in the limit of large values of the radial coordinate, tends to a constant value, which is independent on the parameters describing the model. Therefore a brane geometry admitting a one-parameter group of conformal motions may provide an explanation for the dynamics of the neutral hydrogen clouds at large distances from the galactic center, which is usually explained by postulating the existence of the dark matter.

Specific topics covered include radio-quiet quasars, radio-loud quasars, moderate-luminosity AGNs in X-ray surveys, and future prospects. No significant changes in AGN X-ray emission properties have yet been found at high redshift, indicating that the small-scale X-ray emission regions of AGNs are insensitive to the dramatic changes on larger scales that occur from z = 0-6. X-ray observations are also constraining the environments of high-redshift AGNs, relevant emission processes, and high-redshift AGN demography.

description: We report an experimental investigation of the role of measurement in quantum metrology when the states of the probes are mixed. In particular, we investigated optimized local measurements and general global projective measurements, involving entangling operations, on noisy Werner states of polarization entangled photons. We demonstrate experimentally that global measurement presents an advantage in parameter estimation with respect to the optimized local strategy. Moreover, the global strategy provides unambiguous information about the parameter of interest even when the amount of noise is not well characterized. This shows that the coherence in quantum operations, such as the Bell-state projection device used in our protocol, can be used to further boost the quantum advantage in metrology and play a fundamental role in the design of future quantum measurement devices.

description: Dynamics in correlated quantum matter is a hard problem, as its exact solution generally involves a computational effort that grows exponentially with the number of constituents. While a remarkable progress has been witnessed in recent years for one-dimensional systems, much less has been achieved for interacting quantum models in higher dimensions, since they incorporate an additional layer of complexity. In this work, we employ a variational method that allows for an efficient and controlled computation of the dynamics of quantum many-body systems in one and higher dimensions. The approach presented here introduces a variational class of wavefunctions based on complex networks of classical spins akin to artificial neural networks, which can be constructed in a controlled fashion. We provide a detailed prescription for such constructions and illustrate their performance by studying quantum quenches in one- and two-dimensional models. In particular, we investigate the nonequilibrium dynamics of a genuinely interacting two-dimensional lattice gauge theory, the quantum link model, for which we have recently shown -- employing the technique discussed thoroughly in this paper -- that it features disorder-free localization dynamics [P. Karpov et al., Phys. Rev. Lett. 126, 130401 (2021)]. The present work not only supplies a framework to address purely theoretical questions but also could be used to provide a theoretical description of experiments in quantum simulators, which have recently seen an increased effort targeting two-dimensional geometries. Importantly, our method can be applied to any quantum many-body system with a well-defined classical limit.

description: Malawi continues to rely on maize for household food security. Policies to enhance food security continue to target maize production. Traditionally production and use of cassava was localized in lakeshore areas until the past two decades when maize production was increasingly affected by rainfall variability. Cassava as an alternate food crop has rapidly gained popularity and commercialization of the cassava sector is steadily taking off. Policy and institutional support to diversify the food security basket and promote the diversified applications of cassava in non-food sector has propelled cassava production in nontraditional growing areas. Production has more than quadrupled over the last decade with production of sweet cassava rapidly expanding in nontraditional areas.

description: Localization of electronic states in disordered thin layered systems with b layers is studied within the Anderson model of localization using the transfer-matrix method and finite-size scaling of the inverse of the smallest Lyapunov exponent. The results support the one-parameter scaling hypothesis for disorder strengths W studied and b=1,...,6. The obtained results for the localization length are in good agreement with both the analytical results of the self-consistent theory of localization and the numerical scaling studies of the two-dimensional Anderson model. The localization length near the band center grows exponentially with b for fixed W but no localization-delocalization transition takes place.

description: Aplodelphys gen. nov.
Diagnosis. Body cylindrical, consistingof unsegmented prosome and small urosome. Body surface covered with fine spinules. Urosome unsegmented, positioned at posterior end of prosome, bearing lobate caudal rami. Caudal setae absent. Rostrum and antennules lacking. Antenna small, 2-segmented with terminal claw. Labrum large, conical, posteriorly-directed, extending slightly beyond distal tip of leg 1 rami. Mouthparts absent. Legs 1 and 2 positioned ventrally and directed posteriorly. Leg 1 biramous; rami digitiform, unsegmented and conical; both rami equal in length. Leg 2 as in leg 1 but with slightly smaller rami. Legs 3–5 absent.
Type species. Aplodelphys conica gen. et sp. nov. by original desgination.
Etymology. The name is derived from the Greek apl (=simple) and - delphys, referring to the simple body structure of the new genus.
Remarks. Aplodelphys gen. nov. shows extreme reduction in appendages, a feature that it shares with Socotradelphys gen. nov. and Paranoplodelphys. Aplodelphys gen. nov. lacks ventrolateral processes on the cephalosome and bears biramous legs 1 and 2, which separates it from Scocotradelphys gen. nov. It lacks antennules but has paired antennae and a biramous leg 2, which serve to distinguish it from Paranoplodelphys.

description: Magyarországon a termálenergiára és a megújuló energiára (faapríték-fűtés) alapozott hajtatásos zöldségtermelés kilátásai biztatóak. A zöldséghajtatásban elsősorban a 3 és 5 hektáros méretű üzemek azok, amelyek geotermikus energiával és biomasszával fűtve képesek olyan mértékű üzemi eredményt elérni, amely nagy biztonsággal megalapozhatja a talaj nélküli integrált zöldséghajtatás fejlesztését. A fosszilis energiahordozók 100 Watt fűtési teljesítményre jutó üzemi eredménye a 0,5 és 1 ha-os üzemméretek mellett negatív, vagy csak nagyon alacsony eredményeket értek el a vizsgált zöldséghajtató modellgazdaságokban. Az üzemméretből származó előnyök az összes fűtési mód esetén 3 ha-os zöldséghajtató modellekben jelentkeznek először, de a méret növelésével az 5 és 10 ha-os modellüzemeknél a mutatószám értéke csak kis mértékben emelkedett. --------------------------------------------- The prospects for forced vegetable production based on thermal energy and renewable energy (heating with wood chips) are promising in Hungary. In this field, it is predominantly businesses with 3 or 5 hectares of land, using geothermal energy and biomass heating, which are able to achieve profits allowing them to launch soilless integrated vegetable forcing operations. The operating result of fossil sources of energy per 100 W of heating capacity enabled businesses with 0.5 and 1 hectare of land to only achieve negative or very low profits in the model farms studied. Benefits of the scale of business first appeared in the vegetable forcing models farming on 3 hectares for all forms of heating, but increasing land size only caused a slight increase of the index figures for the model farms with 5 or 10 hectares of land.
Topics in mean curvature flow of hypersurfaces

Publisher: name: University of British Columbia

description: In this thesis we study the possible solutions of the mean curvature flow problem restricted to hypersurface geometries: We give a complete exposition of the theory contained in some of the articles included in the bibliography. The text is divided in three parts. The first part consist of an informal discussion on some useful knowledge in partial differential equations of parabolic type. The second part of the text is the core of the thesis: It contains a detailed exposition (with full proof of all main results) of the now classical work of Huisken and Hamilton on the MCF of compact-convex initial surfaces. The main result state the existence of a long time solution of the mean curvature flow and that this smooth solution converge to a round point. The third part is meant to be an introduction to some further developments under less restrictive initial data. In some situations the flow can generate singular points and then a smooth solution do no longer exist after a given finite time interval: We characterize in a simple way some of these singularities. An informal discussion on some important results of MCF of entire graphs then conclude our work.

description: Cosmic strings have gained a great interest, since they are formed in a large class of brane inflationary models. The most interesting story is that cosmic strings in brane models are distinguished in future cosmological observations. If the strings in brane models are branes or superstrings that can move along compactified space, and also if there are degenerated vacua along the compactified space, kinks interpolate between degenerated vacua become ``beads'' on the strings. In this case, strings turn into necklaces. In the case that the compact manifold in not simply connected, a string loop that winds around a nontrivial circle is stable due to the topological reason. Since the existence of the (quasi-)degenerated vacua and the nontrivial circle is a common feature of the brane models, it is important to study cosmological constraints on the cosmic necklaces and the stable winding states. In this paper, we consider dark matter production from loops of the cosmic necklaces. Our result suggests that necklaces can put stringent bound on certain kinds of brane models.

description: We carried out UBVRcIc photometric study of three poorly studied young open clusters IC 1442, King 21, and Trumpler 7 (Tr 7). We obtained 263, 244, and 128 member stars using Gaia DR2 proper motions and parallaxes in IC 1442, King 21, and Tr 7, respectively. The reddening, E(B-V), was derived to be 0.54+/-0.04, 0.76+/-0.06, and 0.38+/-0.04 mag for these clusters. The comparison of observed colour-magnitude diagrams (CMDs) with solar metallicity isochrones yields log(Age) = 7.40+/-0.30, 7.70+/-0.20, and 7.85+/-0.25 yr and corresponding distances 2847+/-238, 2622+/-156, and 1561+/-74 pc for IC 1442, King 21, and Tr 7, respectively. The estimated mass function (MF) slopes are found to be -1.94+/-0.18, -1.54+/-0.32, and -2.31+/-0.29 for IC 1442, King 21, and Tr 7, respectively. The study of MF slopes determined separately in the inner and the outer regions of these clusters gives a steeper slope in outer region which suggests spatial variation in slope and mass segregation in the clusters. We found evidence of mass segregation after dynamical study in these clusters. The obtained relaxation time is 74, 26, and 34 Myr for the clusters IC 1442, King 21, and Tr 7, respectively. The mass segregation in IC 1442 may be caused by early dynamical relaxation. The estimated relaxation time is well below to the ages of King 21 and Tr 7 which indicates that these clusters are dynamically relaxed.

description: A mezőgazdaságban egy-egy tevékenységnél magas tőkeigényű beruházások szükségesek a termeléshez. Ezek fényében érthető, hogy a gazdálkodó a piac változékonyságát csak lassan képes követni, ezért több időbe telik a piaci hatásokra történő reagálás. Napjaink vezetőinek ma már nem elég kifogástalanul ismerni a növénytermelés rejtelmeit, megfelelő ökonómiai látásmód is szükséges. Ehhez nyújthat segítséget a szemléletes jövedelemtérkép, amely a gazdálkodónak egyértelmű információkkal szolgál a jövedelmezőségről, és amit hazánkban eddigi ismereteink szerint még nem készítettek. Jelen publikációnk a jövedelemtérképezés gyakorlati alkalmazhatóságát hivatott bemutatni. A jövedelemtérképek hasznosítható többletinformációkat nyújtanak a hozamtérképekhez képest. Hosszabb időszakot felölelő adatsorok esetén vitathatatlan előnyük, hogy szemléletesen képesek mutatni a jövedelmet, ezáltal megerősíthetik a döntéshozókat munkájukban. ----------------------------------- Certain agricultural products require large investments to be made. This makes it difficult to adapt to changes in the market and makes it longer until farmers respond to market influences. Today’s decision-makers need not only be aware of all details of crop growing – they must also have a good economical vision. They may be assisted in this by the detailed revenue map, which provide farmers clear information on profitability. As far as we are aware, no such map has yet been created in Hungary. This publication is intended to demonstrate the practical application of revenue mapping. Revenue maps offer practically usable additional information over yield maps. Their advantage is that they offer a visual representation of revenues based on data for longer periods, which may confirm decision-makers in their work.
Orbital ordering, Jahn-Teller distortion, and resonant x-ray scattering in KCuF3

description: The orbital, lattice, and spin ordering phenomena in KCuF3 are investigated by means of LDA+U calculations, based on ab-initio pseudopotentials.We examine the Cu-3d orbital ordering and the associated Jahn-Teller distortion in several different spin-ordered structures of KCuF3. The ground state is correctly predicted to be an A-type antiferromagnetic structure, and the calculated Jahn-Teller distortion agrees also well with experiment. Concerning the orbital ordering, we find that even for a highly ionic compound such as KCuF3, the orbital-order parameter is significantly reduced with respect to its nominal value due to Cu(3d)--F(2p) hybridization. We also calculate the Cu K-edge resonant x-ray scattering spectra for Bragg reflections associated with orbital order. Consistent with previous studies, we find that the resonant signal is dominated by the structural anisotropy in the distribution of the F neighbors of the resonant Cu atom, and that the Cu-3d orbital ordering has only a minor influence on the spectra. Our LDA+U results, however, also indicate that a change in the magnetic structure has a small influence on the Jahn-Teller distortion, and hence on the resonant spectrum, in the conventional (room-temperature) crystallographic structure of KCuF3. This may indicate that the large change observed experimentally in the resonant signal near the Néel temperature is related to a low-temperature structural transformation in KCuF3.
