THE PRODUCING OF THE FUEL PELLETS FROM A MIXTURE OF OAT STRAW AND POTATO PULP

The aim of the research described in the present paper was to determine the best possible parameters for producing biofuel in the form of pellets from a mixture of oat straw and potato pulp. The research of the densifi cation process of mixtures were carried out on SS-4 stand whose main element is a P-300 pellet mill with a ‘fl at matrix-densifi cation rolls’ working system. The densifi cation process of mixtures tests were conducted for the working gap between the densifi cation roll and the fl at matrix, measuring 0.4 mm, and for the mass velocity of the mixtures of approx. 50 kg·h–1. The diameter of the openings in the matrix used in the tests equalled 8 mm, and the length of the openings in the matrix was 28 mm, while the rotational speed of the matrix was 280 rpm. During the measurements, the author assessed the infl uence of the content of potato pulp (10, 20, 30, and 40%) in the mixture with oat straw on the electric energy consumption of the motor which was driving the pellet mill and on the kinetic durability of obtained pellets. The kinetic durability of pellets was determined with the use of a Holmen tester. The pellets were kept in the chamber of Holmen tester for 60 s. Designating the materials moisture (potato pulp, oat straw and mixtures potato pulp and oat straw) was performed pursuant to Polish Standards with the use of a WPE 300S scale-dryer. Increasing the content of potato pulp in the mixture with oat straw from 10 to 40% brought about a reduction of the of the electric energy consumption of the pellet mill by approx. 66% (from 5.94 to 2.03 kW) with a simultaneous decrease in the kinetic durability of the pellets by approx. 40% (from 94.65 to 54.99%). The research results obtained in the working system of the pellet mill, made it possible to conclude that in order to produce pellets of satisfactory quality (density and kinetic durability), the content of potato pulp added to oat straw should not exceed 20%. The performed research has made it possible to develop a detailed technology of producing heating pellets, which resulted in fi ling a patent application.
Increased of hypoglycemic effect and pancreatic regeneration of Pandanus amaryfollius leaves ethyl acetate extract in streptozotocin-induced diabetic rats

The number of diabetes mellitus patients is continuously growing. Diabetes is a chronic disease and/or a major endocrine disorder caused by a deficiency of insulin production by pancreas or low insulin productivity. Hypoglycemic potentials have been widely examined from plant ingredients to substitute diabetes medicines and treatments. The objective of this research was to investigate a hypoglycemic activity and pancreatic cell regeneration of ethyl acetate extract from Pandanus amaryfollius leaves in streptozotocin-induced diabetic rats. The ethyl acetate extract of pandan leaves was prepared by crushing, macerating, filtrating and evaporating the leaves. Forty rats were grouped into five groups: (1) normal controlled rats, (2) diabetic controlled rats, (3) diabetic rats with feed standard and 0.985 mg/20g diet ethyl acetate extract (K1), (4) diabetic rats with feed standard and 1.97 mg/20g diet ethyl acetate extract (K2), and (5) diabetic rats with feed standard and 2.955 mg/20g diet ethyl acetate extract (K3). The treatments were being conducted for 28 days; blood sampling was taken every 7 days to be analyzed its blood glucose levels, and the final research stage was to analyze its blood insulin levels and MDA levels in the rats’ liver and pancreatic histology. The result showed that the intake of ethyl acetate extract in the diabetic rats could lower their blood glucose levels. The higher the dose of ethyl acetate extract resulted in the lower blood glucose levels, the higher blood insulin levels, and the lower liver damage due to the oxidative stress. In addition, the higher the dose of ethyl acetate extract resulted in the lower insulin resistance in the islet of Langerhans, indicated the smaller the volume of pancreatic β-cells. However, the insulin resistance decreased and the insulin secretion increased; hypoglycemic ability of ethyl acetate extract of fragrant pandan leaves remained high.
University of Groningen Quantifying the Influence of Component Failure Probability on Cascading Blackout Risk

The risk of cascading blackouts greatly relies on failure probabilities of individual components in power grids. To quantify how component failure probabilities (CFP) influences blackout risk (BR), this paper proposes a sample-induced semianalytic approach to characterize the relationship between CFP and BR. To this end, we first give a generic component failure probability function (CoFPF) to describe CFP with varying parameters or forms. Then the exact relationship between BR and CoFPFs is built on the abstract Markov-sequence model of cascading outages. Leveraging a set of samples generated by blackout simulations, we further establish a sample-induced semianalytic mapping between the unbiased estimation of BR and CoFPFs. Finally, we derive an efficient algorithm that can directly calculate the unbiased estimation of BR when the CoFPFs change. Since no additional simulations are required, the algorithm is computationally scalable and efficient. Numerical experiments well confirm the theory and the algorithm.
Assessment of non-surgical periodontal treatment combined with Low-Level Laser Therapy ( LLLT ) in chronic periodontitis patients suffering from Iron Deficiency Anemia ( IDA )

Hence there are many chronic diseases known as catalyzers of destructive alterations in the periodontal complex, among them Iron Deficiency Anemia, the purpose of this study is to evaluate the assessment of non-surgical periodontal treatment combined with LLLT in chronic periodontitis patients suffering from IDA. Subjects were selected from patients treated at the University Dentistry Clinical Center of Kosovo in Prishtina, included 63 participants suffering from Iron Deficiency Anemia only, followed by patients with IDA and any concomitant chronic condition and control group consisted of subjects with Chronic Periodontitis. (from October 1st, 2016 until March 31st, 2017). Patients suffering from Chronic Periodontitis were divided into three groups, suffering from IDA (Group A, 21 subjects), IDA and Chronic Disease subjects (Group B, 21 subjects) and the control group with normal iron values suffering from chronic periodontitis (Group C, 21 subjects). In this study we had also inclusion and exclusion criteria, Criteria for classifying Debris, Loe-Silness Gingival Index.LLLT adjusted to (660 nm, 10mW , 8 min/daily, in contact with gingiva); model continuously in the next five days. Blood samples were taken at baseline and at 2-month recall visit. As far as the gender distribution between groups, it’s evident that male subjects are dominant X(m)=39; n=63 in all groups (Chi=0.28; p>0.05). There was no significant difference regarding age discrepancy among subjects (F=11.6; p<0.01). IDA patients groups (A and B) have more tobacco users compare to overweight/obese group 40.9% (Chi=0.31, p>0.05). The differences in GI, OHI-s and CAL values were statistically significant among groups at 2 months. A p value <0.05 was considered significant. IDA patients represented in group B showed higher values for PI ,GI and CAL. CPITN values are much higher in group B compare to group A and the control group C (Chi = 17.9; p<0.05). Comparative data analysis of our measurements showed that root planning and scaling of periodontal pockets resulted in improved results for PI, GI, CAL after two months – compared to baseline measurement outcomes. Meanwhile, Hb and SI levels at baseline and after two months demonstrated weak correlation with periodontal parameters. Clinical article (J Int Dent Med Res 2019; 12(2): 533-539)
Interaction between Fibrinogen and Insulin-Like Growth Factor-Binding Protein-1 in Human Plasma under Physiological Conditions

Fibrinogen is a plasma glycoprotein and one of the principle participants in blood coagulation. It interacts with many proteins during formation of a blood clot, including insulin-like growth factors (IGFs) and their binding proteins (IGFBP). Fibrinogen complexes were found as minor fractions in fibrinogen preparations independently of the coagulation process, and their presence influences the kinetics of polymerization. The idea of this work was to investigate whether fibrinogen in human plasma interacts with IGFBPs independently of the tissue injury or coagulation process. The results have shown that fibrinogen forms complexes with IGFBP-1 under physiological conditions. Several experimental approaches have confirmed that complexes are co-isolated with fibrinogen from plasma, they are relatively stable, and they appear as a general feature of human plasma. Several other experiments excluded the possibility that alpha-2 macroglobulin/IGFBP-1 complexes or IGFBP-1 oligomers contributed to IGFBP-1 immunoreactivity. The role of fibrinogen/IGFBP-1 complexes is still unknown. Further investigation in individuals expressing both impaired glucose control and coagulopathy could contribute to identification and understanding of their possible physiological role.

Predictors of school affective engagement during elementary school: A systematic review

O envolvimento escolar dos alunos tem sido extensivamente estudado devido ao seu papel na adaptação e sucesso escolares. A presente revisão sistemática tem como objetivos analisar os preditores e fatores associados ao envolvimento escolar, no domínio afetivo, na infância (6-12 anos). Esta revisão analisa estudos empíricos publicados entre 1997 e 2017, os quais foram selecionados a partir de critérios pré-definidos. Somente oito estudos foram incluídos nesta revisão. A maioria são estudos quantitativos e longitudinais que apresentam uma qualidade metodológica adequada. Os resultados indicam uma associação positiva entre o apoio do professor e o envolvimento escolar afetivo. Verificou-se ainda a existência de outras variáveis relacionais menos estudadas como preditoras do envolvimento escolar afetivo, tais como fatores relacionados com a família e com os pares. Poucos estudos averiguaram o papel de fatores individuais, embora a investigação encontrada sugira que as raparigas têm níveis mais elevados de envolvimento escolar afetivo que os rapazes. A escassez de estudos focados nos preditores do envolvimento escolar afetivo durante a infância indica que é necessária mais investigação nesta área. São identificadas as limitações metodológicas dos estudos, sendo indicadas algumas sugestões para investigação futura.
Augmenting Abstract Meaning Representation for Human-Robot Dialogue

We detail refinements made to Abstract Meaning Representation (AMR) that make the representation more suitable for supporting a situated dialogue system, where a human remotely controls a robot for purposes of search and rescue and reconnaissance. We propose 36 augmented AMRs that capture speech acts, tense and aspect, and spatial information. This linguistic information is vital for representing important distinctions, for example whether the robot has moved, is moving, or will move. We evaluate two existing AMR parsers for their performance on dialogue data. We also outline a model for graph-to-graph conversion, in which output from AMR parsers is converted into our refined AMRs. The design scheme presented here, though task-specific, is extendable for broad coverage of speech acts using AMR in future task-independent work.
RADIAL SHRINKAGE OF SINGLE-WALLED CARBON NANOTUBE BUNDLES AT HIGH TEMPERATURES

X-ray diffraction measurement on single-walled carbon nanotube (SWNT) bundles revealed radial shrinkage in the temperature range from 290 to 1600 K. The hysteretic temperature dependence was observed in the virgin run of cycling measurements. The result is discussed in terms of desorption of molecules from intertube space in the bundles and of a magnetic phase transition of ferromagnetic metal catalyst particles. In the second and third runs a simple temperature dependence was found. The linear expansivity as a function of temperature is determined by a linear-regression of the data between 290 and 330 K to be (-1.52±0.05) x 10 K, and of the data between 1300 and 1550 K to be (-2.48±0.05) x 10 K. The volume thermal expansion coefficient for the bundles is suggested to be negative over the measured temperature range by assuming that the tube-axis expansion is similar to the in-plane expansion for graphite.
PDFlib PLOP: PDF Linearization, Optimization, Protection Page inserted by evaluation version

In this paper, it is argued that differences in how one relates the genome to its surrounding contexts leads to diverse interpretations of the term epigenetics. Three different approaches are considered, ranging from gene-centrism, over gene-regulation, to dynamic systems approaches. Although epigenetics receives its widest interpretation in a systems approach, a paradigmatic shift has taken place in biology from the abandonment of a gene-centric position on to the present. The epistemological and ontological consequences of this shift are made explicit.
Debasements and Small Coins : An Untold Story of Commodity Money

This paper draws quantitative implications for some historical coinage issues from an existing formulation of a theory that explains the society’s demand for multiple denominations. The model is parameterized to match some key monetary characteristics in late medieval England. Inconvenience for an agent due to a shortage of a type of coin is measured by the difference between his welfare given the shortage and his welfare in a hypothetical scenario that the mint suddenly eliminates the shortage. A small coin has a more prominent role than small change. Because of this role, a shortage of small coins is highly inconvenient for poor people and, the inconvenience may extend to all people when commerce advances. A debasement may effectively supply substitutes to small coins in shortage. Large increase in the minting volume, cocirculation of old and new coins, and circulation by weight, critical facts constituting the debasement puzzle, emerge in the equilibrium path that follows the debasement.

Tridacna noae ( Röding , 1798 ) – a valid giant clam species separated from T . maxima ( Röding , 1798 ) by morphological and genetic data

The taxonomic status of a giant clam species Tridacna noae (Röding, 1798) in relation to its congener T. maxima (Röding, 1798) was examined by a combination of molecular and morphological analyses. Until recently, T. noae was considered conspecifi c with T. maxima. However, in this study, among the four genes (COI, 16S rRNA, 18S rRNA, 28S rRNA) examined, two (i.e., 16S rRNA and COI) genes grouped T. maxima into two distinct clades, suggesting that a cryptic species was involved. The genetic distance of the 16S rRNA gene between T. maxima and cryptic species was 0.042–0.048. In contrast, the differences within the clades comprising T. maxima and the cryptic species were 0–0.003 and 0–0.005, respectively. A careful comparison of morphological traits revealed differences between T. maxima and the cryptic species, and the shells of the latter species were consistent with the fi gures referred to by Röding for the species he named ‘noae’. Tridacna noae differs from T. maxima in the appearance and arrangement of hyaline organs on the mantle in living specimens. In contrast, shell characters such as numbers of radial ribs and prominence of rib scales, were relatively unreliable. Occasionally, prominent rib scales only grew in one valve of an individual, e.g., in one T. maxima specimen from Hongchia. Based on previous and the present studies, here, a formal taxonomic description of Tridacna noae (Röding, 1798) with the designation of a neotype is provided.

RESISTANCE OF DIFFERENT COTTON VARIETIES TO COTTON LEAF CURL VIRUS UNDER FIELD CONDITIONS

Nine cotton varieties (228/19, S-12, AC-134, MNH-440, MNH-410, MNH295, MNH-395, MNH-329, and MNH-93) were evaluated for Cotton Leaf Curl Virus (CLCV) resistance. For CLCV, percent-infected plants were recorded on 62, 75, 82, 97, 104 and 114 days after planting (DAP). For whitefly, adults per leaf were counted on all these days expect 62 DAP. Difference in percent CLCV infected plants was nonsignificant among varieties on the first observation (62 DAP). From 75 to 114 DAP difference in percent infected plants was significant among the varieties tested. On 114 DAP, MNH-93 had the lowest infection (5.17%) followed by MNH-329 (9.93%). Highest infection was recorded in 228/19 (46.97%) and the second highest in S-12 (31.3%). Infection in other varieties was 18 to 28%. It was concluded that MNH-93 was resistant, MNH-329 moderately resistant, 228/19 highly susceptible and S-12 susceptible to CLCV. Whitefly, Bemisia tabaci (Genn.) population was not significantly different among varieties on any observation date, which indicates that response of the tested varieties to CLCV was independent of the whitefly population.
2 SAFE BETS OR HOT HANDS ? HOW STATUS AND CELEBRITY INFLUENCE NEWLY PUBLIC FIRMS ’ STRATEGIC ALLIANCE FORMATIONS

Social approval assets are a class of intangible assets based on favorable stakeholder perceptions and evaluations. In this study we theorize how social approval assets with different sociocognitive content serve as frames that influence the way equivocal information about a firm is interpreted. We argue that when assessing equivocal information cues, different frames will focus attention on the aspects of the information cue that are congruent with the frame. We also argue that since the assets present incongruent frames, possessing both leads to weaker effects than possessing each asset alone. Specifically, we examine how firm celebrity—an asset derived from perceived non-conformity that engenders high levels of attention and excitement—and status—an asset based on occupying a desirable position in a social hierarchy—influence the interpretation of a newly-public firm’s underpricing, and thus its effect on the firm’s strategic alliance formations. We also consider whether possessing both status and celebrity is associated with fewer strategic alliances than possessing one asset or the other. We test these theoretical ideas in the ambiguity-ridden context of Internet IPOs during the commercial dawn of the Internet between 1995 and 2000. Our findings generally support our arguments, providing new theory and evidence about the dynamics of information and frame (in)congruence, as well as about the framing effects of social approval assets with different socio-cognitive content.
The Search for Life on Mars - and Earth: A Call for Objectivity

The primary focus of NASA‟s Mars and other planetary exploration programs, such as Titan, Enceladus, and Europa, “is to determine if life is or was present. ” The author suggests that NASA‟s stated primary focus should, therefore, include a re-examination of the data from the 1976 Viking Mission Labeled Release (LR) life detection experiment. That experiment obtained repetitive strong positive signals supported by a variety of controls, altogether signifying the detection of microbial metabolism in the top few centimeters of the surface of Mars. The data fall well within those obtained from hundreds of terrestrial LR tests of soils and microbial cultures that made up the response library assembled for the Viking LR experiment. No physico-chemical theory or experiment of the many attempted over the years has duplicated or explained away the Viking LR results as indicative of life. Together with pertinent findings on Mars and Earth since Viking, the possibility of microbial life on Mars has become a singular scientific issue warranting the herein requested reexamination of the Viking LR data. For those seeking further proof, a new experiment, based on the Viking LR legacy, is proposed. It seeks not only to confirm the Viking results but, if confirmed, to determine whether the Martian life is related to terrestrial life or is alien in nature. Both objectives will be determined by probing the active agent on Mars for a chiral preference in reacting with the LR nutrient. Chiral preferences are a strong characteristic of all known life, but play no role in chemical reactions. A finding of chiral metabolism would unambiguously prove the existence of extant life, even to the most critical observers. Moreover, were a chirality found that was different to that now known for terrestrial life, the finding would be strong evidence for an independent origin of that life form, even if it were found on Earth.
Reproductive response of Pelibuey sheep to the application of recombinant bovine somatotropin and a metabolic restorative preparation

Abstract: The objective of this work was to evaluate the effect of recombinant bovine somatotropin (rBST) and of the metabolic restorative preparation Metabolase (MR) on the reestablishment of the post-partum ovarian activity of Pelibuey sheep. Ninety-four ewes, with their respective lambs, were randomly assigned to one of the following treatments: T1, continuous suckling (CS); T2, CS + MR; T3, CS + rBST; and T4, CS + MR + rBST. Ovulating percentages, weight changes in ewes and lambs, incidence of estrus, onset and return to estrus, calving, fecundity, and prolificacy were evaluated. The highest ovulation percentages were recorded for CS in T1 and T2, and the lowest ones for rBST in T3 and T4. The treatments had a significant effect on lamb weight. Ewes in T3 had the lowest incidence of estrus (52.9%), besides a greater onset (26.8±1.9 hours) and return to estrus (66.6%). Calving (86.2%) and fecundity (1.8±0.2) were significantly higher in T2. The application of rBST in ewes increases lamb body weight, due to increased milk production, but affects negatively post-partum reproductive activity due to the loss of ewe body weight.
