Kinetics and equilibrium adsorption of lead (II) ions on olive residues: Effects of chemical activation

Abstract: This work reports on the inﬂuence of treatment conditions on the olive stones for adsorptive lead(II) ions. The olive stones were treated with acidic or alkaline solutions at various concentrations and contact time . The structure and surface properties of the resulting biosorbents were characterized by surface pH, Boehm’s titration and N 2 adsorption–desorption isotherms. The olive stones sample, treated with HNO 3 , possess the highest surface oxygen containing functional groups (3.76 mmol/g), surface area (198 m 2 /g) and pore volume ( 0.081 cm 3 /g) and the more adsorption capacity to the lead ions. The adsorption efficiency was higher for treated of olive stones with HNO 3 than for treated with KOH. However, the weight loss of the adsorbent products was important with HNO 3 treatment. It was also found that the time to reach equilibrium takes less 15 minutes. The effect of contact time, initial concentrations of adsorbate, ionic strength and adsorbent dose on the uptake of lead was studied in batch experiments. The kinetic data were fitted to the pseudo-first order and pseudo-second order, and follow closely the pseudo-second order model. Equilibrium adsorption of Pb(II) were analyzed by the Langmuir, Freundlich and Redlich-Peterson isotherm models. The results reveal that the Redlich-Peterson isotherm models fitted the data .
Etiologie et pathogenie de la maladie du pancreas et de la maladie du sommeil chez les salmonides d'elevage

La maladie du pancreas est une pathologie infectieuse du saumon atlantique et de la truite fario eleves en mer, elle est responsable de necroses pancreatiques qui peuvent conduire, chez le saumon, a la disparition totale du pancreas exocrine ; des lesions cardiaques et musculaires sont aussi observees. La maladie du sommeil est une pathologie infectieuse de la truite arc-en-ciel elevee en eau douce, elle se caracterise par des lesions musculaires importantes, responsables d'un comportement particulier du poisson malade qui se couche sur le flanc ; des lesions pancreatiques et cardiaques sont egalement observees. Ces maladies ont une histopathologie similaire. Une protection acquise contre les deux maladies est obtenue apres exposition a l'une d'entre elles. Ces observations suggerent une parente entre les deux maladies. Dans le materiel virulent responsable de la maladie du sommeil, des particules circulaires et enveloppees de 50 nm sont observees, montrant une etiologie virale
Phenotyping methods and QTL mapping for late leaf spot resistance in cultivated peanut (Arachis hypogaea L.)

Late leaf spot (LLS), caused by Cercosporidium personatum, is a major foliar disease of peanut. LLS resistance is quantitative in nature. To identify genomic regions that control disease resistance, quantitative trait locus (QTL) mapping is required. Obtaining reliable phenotyping data is vital for mapping. Therefore, a population, consisting of 78 recombinant inbred lines (RILs) segregating for LLS resistance, was used for quantitative trait locus (QTL) analysis. Data were collected using three different phenotyping methods and comparisons were made. A set of 447 simple sequence repeat (SSR) and 25 single nucleotide polymorphism (SNP) markers was used for parental screening. The population was genotyped using 141 polymorphic loci. A linkage map with 94 loci, distributed into 19 LGs, was constructed based on the marker segregation data obtained from the population. A total of 7 QTL were identified that explained 10.938. 4% of the variation in the phenotyping data. INDEX WORDS: Peanut, Arachis hypogaea, disease resistance, late leaf spot, Cercosporidium personatum, LLS, phenotyping, quantitative, molecular marker, QTL, mapping, host resistance, detached leaf PHENOTYPING METHODS AND QTL MAPPING FOR LATE LEAF SPOT RESISTANCE IN CULTIVATED PEANUT (Arachis hypogaea L.)
Association of phytoplasmas with yellow leaf syndrome of sugarcane.

Evidence is presented for the association ofplzytoplasmas with symptoms of yellow leaf syndrome of sugarcane (YLS). The phytoplasmas have provisionally been named sugarcane yellows phytoplasmas I and 11 (ScYP I and ScYP I . . The phytoplasmas were consistently detected in leaves of more than forty varieties from eight African countries and 12 countries outside Africa. They were present in all YLS-symptomatic as well as some asymptomatic samples offield-grown cane but not in plants grown from true seed Plzytoplasmn 16s rDNA was confirmed by PCR. Restriction fragment analysis using the primers Rsal and Hael 11 confinned that the PCR-ampliJied products were of phytoplasma rather than of plant or other pathogen origin. Sequences obtained from the intergenic spacer region between the 16s an4 23s rDNA genes confirmed the identity of the phytoplasmas as belonging to the Western X and sugarcane dhite leaf (SCWL) phytoplasmn groups. The association of symptoms of YLS with the presence of sugarcane yellow leaf virus (ScYLV) was found to be poor. R
Wind Value in Hydropower Dominated Electricity Market

This paper studies the interaction between hydro and wind power in hydro-thermal-wind power system. Socially efficient and monopoly hydropower allocation solutions are presented. Market power utilization potential for hydropower is reduced during low demand periods when residual demand crosses the elastic part of thermal supply curve. Conversely, in high demand periods when the residual demand crosses the inelastic part of thermal supply curve, real potential for market power utilization exists. Compared to thermal power systems, wind value factors are high as efficiently allocated hydropower buffers wind power shocks. Monopoly hydroallocation decreases wind power value and the gap to wind values under socially efficient hydropower widens as wind market share increases.
Adsorption, functionalization and electrostatic multipolar interactions at CNT and graphene surfaces

Carbon nanotubes (CNTs) are 1D nano materials, quantization along axis exists; CNT is considered as quantum wire or quantum dot.1 Functionalization is powerful method for tuning CNTs quantum energy levels and physical properties. Functionalization of 2D graphene and bigraphene layers is also applied widely. The theory was developed2 for energy spectra tuning in the semiconducting nanowires and polarons formation as the result of functionalization by molecular layers with (i) radial degree of freedom, (ii) conformational transition in the molecules and (iii) incommensurate structures. Periodic distribution of metals, metal organic3 and conducting polymers at CNT surface was found by TEM.4 The charge transfer3 leads to electron and hole (pair), spatially separated in neighboring substrate (CNT) and a molecule or atom. The aim of this work is theoretical consideration of initial stages of functionalization with the charge transfer. It is shown that the electron-hole pairs can be presented as the dipole and quadrupole moments with long range interaction. We consider situation of enough small molecules with relatively large distance between ones. At short range distances, compared with the molecules size, the proposed method would be applied with higher error. The charge transfer is example of a general contact interaction of molecules with different electro negativity. Thus, in comparison with CNT and graphene we have electronegative molecules with F, Cl, O, N. P, S atoms and electropositive metals or metal-organic complexes. In further consideration we suppose the molecules (atoms) to be electropositive and the electronic clouds of the transferred charge to be negative, they are shown in Figure 1. A dipole vector5 d = qr is shown as arrow between centers of negative and positive charges in Figure 1. Following to5,6 we write dipole-dipole interaction as:
Can SEL Reduce School Violence

Amanda B. Nickerson A researcher says teaching empathy, problem solving, and self-control could lead to safer schools. In light of recent highly publicized and tragic incidents, such as the February 2018 shooting at Marjory Stoneman Douglas High School in Parkland, Florida, school communities are increasingly concerned about student and teacher safety. School leaders, politicians, and community members are frantically seeking solutions to the problem of school violence. Many of the ideas proposed have focused on security and "hardening" schools, and some lawmakers have even suggested arming teachers. One strategy that is more likely to work, if used as part of a comprehensive public health approach, is improved social-emotional learning (SEL).

Applying venn diagram to present bloom’s cognitive level of students of a physics learning about light refraction using developed independent lab work module and PhET simulation “bending light”

Evaluation shows the effectiveness of teaching and learning of a class. Mostly teachers provide evaluation in low cognitive level so students are able to achieve the minimum passing grade. Whereas a good evaluation should use Bloom’s Taxonomy as a basis for classifying student’s cognitive level. It leads teacher to provide a learning that facilitates student’s achievement of high cognitive level, including using independent lab work module. Teachers also typically provide a global report evaluation, i.e. providing the final score only, without presenting the distribution of students’ cognitive level. For this purpose, Venn Diagram is used to show the distribution of students’ cognitive level based on Bloom Taxonomy. This research aimed to present the distribution of students’ Bloom cognitive level using Venn Diagram and to investigate whether the development of independent lab work module about light refraction using PhET simulation “Bending Light“ can make students achieve the cognitive levels of knowing, understanding, applying, and analyzing. The obtained data was analyzed using qualitative descriptive method. The respondents were 17 freshmen of Physics Education and Physics Students of UKSW Batch 2016. The post-test showed that all students achieved higher cognitive levels. Thus, the developed independent lab work module was able to improve students’ cognitive level. Venn Diagram could also simplify the presentation of the distribution of students’ Bloom cognitive level for teachers.
Effet d’une induction émotionnelle sur l’orthographe lexicale d’enfants présentant des troubles du langage écrit et d’enfants normo-scripteurs

Cette recherche a pour but d’etudier l’effet d’une induction emotionnelle negative par la musique sur les performances orthographiques lexicales d’enfants normo-scripteurs et d’enfants presentant des troubles d’apprentissage du langage ecrit. Selon le modele du RAM (Ellis & Moore, 1999), l’emotion altererait les performances en generant des interferences et un cout attentionnel supplementaire. Les resultats montrent que l’effet de l’emotion se manifeste differemment selon le niveau orthographique, impactant les performances chez les enfants presentant des troubles du langage ecrit seulement. Ces resultats sont discutes au regard du modele du RAM.
Clinical and Functional Outcomes of Proximal Fibular Osteotomy on Varus Deformity and Medial Compartment Knee Osteoarthritis

Background: In Low and Middle Income Countries (LMIC), there is an alternative surgical procedure of Proximal Fibular Osteotomy (PFO) has developed for osteoarthritis of knee joint. It is simple, safe and affordable. PFO helps relief pain in almost all patients.Methodology: We retrospectively analysed 38 patients who underwent PFO in our hospital during the period from August to October 2018. Inclusion criteria are patient with moderate to severe symptoms of the knee with grade 2 knee OA on radiographs. Clinical data, Visual Analogue Scale score (VAS score) and American Knee Society Score (AKSS score) were recorded. Patients were followed up at 6 weeks, 12 weeks, and 6 months postoperatively.Results: 38 patients (38 knees) were included in this study out of which 6 knees (L=2, R=4) were of males and 32 knees (L=11, R=21) were of females. The mean age was 52.4 years. The average preoperative VAS score, KSS clinical and functional score was 7.89 ± 1.01 points (range from 4 to 9 points), 47.23 ± 11.05 points (range from 26 to 90 points) and 45.85 ± 16.62 points (range from 0 to 90 points), respectively. At 6 months, the mean visual analogue scale scores significantly decreased to 2.74-2.34 postoperatively. There was significant improvement in the average postoperative KSS clinical and functional scores which is 67.11 ± 10.09 points (range from 31 to 94 points) and 65.67 ± 12.22 points (range from 22 to 100 points), respectively. The ratio of the knee joint space (medial/lateral compartment) increased from an average of 0.38 ± 0.12 preoperatively to 0.56 ± 0.13 postoperatively.Conclusion: The PFO is a promising surgical option in countries that lack financial and medical resources.
The sub-lethal effects of repeated cold exposure in insects

While insect cold tolerance has been well studied, the vast majority of work has focused on the effects of a single cold exposure. However, many abiotic environmental stresses, including temperature, fluctuate within an organism's lifespan. In this thesis I address two major questions. First, does frequency of cold exposure impose additional stress on insects? Second, how does this stress translate to performance and fitness? I first summarize the literature on the effects of repeated cold exposure in insects, critically examining experimental designs. I then address my questions experimentally using four insect species with contrasting life histories and responses to cold exposure. I examine the fitness costs of repeated cold exposure in the chill-susceptible fly Drosophila melanogaster by recording survival, generation time, and number of offspring in flies that had received five 2 h, one 2 h, or one 10 h exposure to -0.5 oC. I found that D. melanogaster trades off immediate survival and reproductive output in response to repeated cold exposure. In the freeze-tolerant caterpillar Pyrrharctia isabella, repeated freezing did not deplete energy reserves, but did damage hemocytes and Malpighian tubules, and led to decreased survival in repeatedlyfrozen caterpillars. Similarly, I found in the freeze-avoiding caterpillar Choristoneura fumiferana that frequency of exposure, independent of period, intensity, or duration of cold exposures significantly increased mortality, likely due to increased investment in cryoprotection at the expense of glycogen reserves. Finally, in the freeze-tolerant fly Eurosta solidaginis, the frequency of exposure, again independent of period, intensity, or duration of cold exposures led to a significant decline in egg production. Repeated cold exposure therefore imposes additional costs to insects, even when intensity and duration of cold are controlled for. This cost may either be a result of accrued damage, or may be energetic as individuals trade off investment in survival mechanisms for reproductive output. Given that many environments are not static, these effects indicate that investigating the effects of repeated stress exposure is important for understanding and predicting physiological responses in the wild.
Krill worldwide: A comparison of hypoxia tolerances of euphausiid species from Atlantic, Pacific and Polar Regions

Modern Oxygen Minimum Zones (OMZs) are extensive and prevail in most of the world oceans. Anthropogenic and climate induced changes will cause OMZs to expand, while coastal hypoxia is assumed to increase in extent and severity. Particularly in Eastern Boundary Upwelling Ecosystems (EBUEs), such as the Humboldt and the Benguela upwelling system, severe OMZs prevail. Animals living in these areas have to physiologically and/or behaviourally adapt to the low oxygen levels or will be excluded from these areas or at least their vertical distribution ranges will be limited. It is assumed that some areas may experience a shift from an abundant and diverse regime to one that is lean and dominated by vertical migrators. Further, temperature is known to impact the hypoxia tolerance of animals negatively. Euphausiids are known as pronounced diel vertical migrators, thus facing different levels of oxygen and temperature within 12 hours and are an important trophic link between primary producers and higher trophic levels throughout the world oceans. The critical oxygen pressure (Pcrit) and the regulation index (RI), as a method to differentiate between oxygen conformity and regulation, were used to assess hypoxia tolerances of different species from different ecosystems. Furthermore, diel vertical migration behaviour was monitored in some species. We will present and compare hypoxia tolerances of different dominant euphausiids species, show how oxygen availability may affect their vertical migration behaviour and assess how future climate scenarios (warming waters and decreasing oxygen content) may alter horizontal and/or vertical distribution of these species.

Conservation genetics of high elevation five-needle white pines

Conservation genetics examines the biophysical factors influencing genetic processes and uses that information to conserve and maintain the evolutionary potential of species and populations. Here we review published and unpublished literature on the conservation genetics of seven North American high-elevation five-needle pines. Although these species are widely distributed across much of western North America, many face considerable conservation challenges: they are not valued for timber, yet they have high ecological value; they are susceptible to the introduced disease white pine blister rust (caused by the fungus Cronartium ribicola) and endemic-turned-epidemic pests; and some are affected by habitat fragmentation and successional replacement by other species.
PUSH-OUT BOND STRENGTH OF DIFFERENT ESTHETIC POSTS AN IN VITRO STUDY

PURPOSE: This in vitro study measured push-out bond strength of different posts as function of radicular regions. Statement of problem: In non circular or excessively flared root canals,prefabricated posts may not fit well,increasing cement thickness and bubbles at coronal level which may alter its mechanical performance causing impaired post retention. Methods:40 sound extracted human central incisors were used in this study. All teeth were endodontically treated and decoronated 2 mm above CEJ. Then were randomly divided into 4 groups of 10 each regarding type of post used:group 1(PD): Polymer infiltrated ceramic,Paradigm MZ 100(3M-ESPE); group 2(FRC)Fiber post,Postec Plus (Ivoclar Vivadent); group 3 (ZR): Lava Zirconium dioxide blocks(3M-ESPE); group 4(CP):Cosmo Post, Zirconium dioxide (Ivoclar Vivadent). All posts were luted with Panavia 21(Kuraray Noritake, Japan). Push-out tests were performed to evaluate the bond strength of different posts at different radicular regions.Data were statistically analyzed using one way (ANOVA)and Scheffe test made pairwise comparison (α=0.05). Results: FRC group recorded the highest bond strength (11.78±0.79MPa). PD group showed higher results (10.10±1.12MPa) than ZR(9.56±0.85MPa) and CP(7.93±0.89 MPa) and the 2 latter groups were not significantly different from each other p≤0.05. Regardless to post type, it was found that middle region recorded highest bond strength means value, then apical region meanwhile the lowest bond strength values were recorded at cervical regions p≤0.05. Conclusions:1Push-out bond strength of different esthetic posts are significantly affected by the type of its materials and manufacturing; FRC recorded the highest bond strength values,PD recorded intermediate values, ZR and CP showed the least values with no significant difference between them. (P≤0.05) 2-Regardless to type of post , the middle radicular region recorded the highest bond strength then apical region, meanwhile cervical region showed the lowest bond strength values P≤0.05.

Combining ability and gene action in chilli (Capsicum annum L.)

Thirteen parents (10 lines and 3 testers) and thirty crosses from line × tester design were evaluated in a randomized block design with three replication during Kharif 2010 and 2011. The results revealed that among the lines SC-23, SC-304, SC-108 exhibited desirable general combining ability effects for most of the traits, while among the testers the Arka Lohit was found to have significant general combining ability effect for number of fruits plant-1, average fruit weight, fruit length, yield hectare-1 and number of seeds fruit-1. In general, The specific combining ability variances were higher than general combining ability variances for all the characters indicating the predominance of non additive gene action. The crosses combinations SC-502 × Arka Lohit, SC-23 × Local, SC-814 × Local and SC-23 × Kashmir Long-1 were identified as good specific combiners for most of the traits.
