Abstract:

Abstract This article presents the results of scientific-pedagogical research, which consisted in analyzing the American experience of the Dalton plan in the schooling of the Netherlands, the ranking surveys according to strict criteria, and the implementation of an adapted version of the original American pedagogical model of the Dalton Plan in the schooling of Holland; characterizing the features of the introduction of the Dalton Plan into the Dutch educational systems. While researching the works of M. Montessory, H. Parkhurst and D. Lager, had been examined as the main source of the study. The archival documents of the biggest collection of Helen Parkhurst papers of the Archive of University of Wisconsin Stevens Point had been analyzed. It was studied that American experience of the Dalton Plan is top ranked among private institutions of the country. It is obvious that after the United States, the country of the Dalton Plan origin, the continental Europe and Holland have a dominant position regarding the implementation of the Dalton plan in the educational systems. It is stated that schools implementing the Dalton Plan are united in recognizing the fact that such a pedagogical model ensures the development of the student’s individuality and his social experience. The special advantage the Dalton students obtain is the ability to use different approaches and sources in seeking information that is necessary for the organization and achievement of their own research. The ideas of the Dalton Plan can be justified in the light of modern theory and research. The Dalton Plan was successfully implemented into the primary and secondary schools of the Netherlands ranked the counrty11th in the world education survey. The Dalton Plan philosophy became one of the components of the complicated Dutch educational system.

Abstract:

In research focused on self-efficacy it is usually teacher-related phenomena that are studied, while the main aspects related to pupils are rather neglected, although self-efficacy itself is perceived as a belief in one’s own abilities. Evidently, this strongly influences the behavior of individuals in terms of the goal and success in mathematical problem-solving. Considering that alternative teaching methods are based on the principle of belief in one’s own ability (mainly in the case of group work), higher self-efficacy can be expected in the pupils of teachers who use predominantly the well-working pupil-centered pedagogies. A total of 1133 pupils in grade 5 from 36 schools in the Czech Republic were involved in the testing of their ability to solve mathematical problems and their mathematical self-efficacy as well. Participants were divided according to the above criteria as follows: (i) 73 from Montessori primary schools, (ii) 332 pupils educated in mathematics according to the Hejný method, (iii) 510 pupils from an ordinary primary school, and (iv) 218 pupils completing the Dalton teaching plan. In the field of mathematical problem-solving the pupils from the Montessori primary schools clearly outperformed pupils from the Dalton Plan schools (p = 0.027) as well as pupils attending ordinary primary schools (p = 0.009), whereas the difference between the Montessori schools and Hejný classes was not significant (p = 0.764). There is no statistically significant difference in the level of self-efficacy of pupils with respect to the preferred strategies for managing learning activities (p = 0.781). On the other hand, correlation between mathematical problem-solving and self-efficacy was confirmed in all the examined types of schools. However, the correlation coefficient was lower in the case of the pupils from the classes applying the Hejný method in comparison with the pupils attending the Montessori schools (p = 0.073), Dalton Plan schools (p = 0.043), and ordinary primary schools (p = 0.002). Even though the results in mathematical problem-solving are not consistent across the studies, the presented results confirm better performance of pupils in some constructivist settings, particularly in the case of individual constructivism in the Montessori primary schools. The factors influencing lower correlation of self-efficacy and performance in mathematical problem-solving ought to be subject to further investigation.

Abstract:

The article reveals the attempt of the Bolshevik regime in the first half of the 20s of the last century to choose a new concept and model of education, to develop and implement educational reforms, in particular: attempts to replace the school with an orphanage, introduction of a comprehensive system, Dalton-Plan, American literacy methods and projects, brigade-laboratory method and others.It is noted that there was a search for solutions to theoretical and practical problems of education and social education of children in Ukraine.It is pointed out that the implementation of educational policy was complex and ambiguous, especially after Ukraineʼs accession to the USSR and changes in the socio-political situation in the country, which created hope for the construction of a new system of education.Objective and subjective difficulties in the implementation of educational reforms are as follows: reconstruction of the war-torn economy of Ukraine, economic crisis and economic reform, insufficient funding of secondary school, the principles of staffing schools, problems of their social composition, complex social-political life of Ukraine, ideology of the education system by the Soviet authorities, propaganda of the leadership of the People's Commissariat of Education, unwillingness of teachers and students to radical changes in the education system, etc.It is concluded that the ideas of pedocentrism, activity approach to teaching, project methods, research and others developed in the 1920s are actively used in the modern school.It is concluded that the ideas of pedocentrism, activity approach to teaching, project, research and other methods, developed in the 1920s are actively used in the modern school. Keywords: school education, educational reforms, complex system, Dalton-Plan, American method of teaching literacy, project method, brigade-laboratory method.

Abstract:

The article examines certain aspects of the development of self-education in China from ancient times to the present. The urgency of self-education is argued, taking into account the challenges of our time and the policy of the PRC to achieve the quality of education and the formation of an open intellectual society. The article presents a retrospective analysis and essential characteristics of the development of self-educational activity in the context of self-learning, self-training, self-education, individualization and informatization of education. Separate forms of organization of self-educational activity in China are revealed through the introduction of the models «Dalton-plan», «Shenben» and others. Some problems and prospects of informatization and digitalization of education, as well as online education in relation to selfeducation activities in the country are shown.

Researched is continuity of secondary and higher vocational education’s system, gives is characteristic of the main teaching and learning activities’ methods in secondary and higher vocational educational institutions in the first half of the 20th century in Volga region. The choice of territorial framework is due to the fact, that Volga region is central one of Russia, the particularities of the system of secondary and higher vocational education’s development are typical for other regions of Russia. In the first half of the 20th century future specialists training’s methodological and methodological base and law-making execution of activities of secondary and higher vocational education institutions’ legal framework took place in Volga region, and that has determined the choice of chronological framework in this article. The authors address teaching and learning activities, used by teachers for learning process’s organization in Volga region’s educational institutions, pick out their advantages and disadvantages. The main methods are: “Dalton plan” with various forms of specially concerted activity, brigade-laboratory method, based on students’ work in team and tasks’ conduct independent operations, and comlpex method, formed up knowledge elicitation (for example, areas of interest and inclinations). Explanatory-illustrative methods of learning, procreational problem, partly search (heuristic), partly research (experimental) methods were used for preparing future specialists at universities.

Abstract:

Our present time is characterised by many contradictions and the aspect of uncertainty indicates a sense of our deep loss of values. Education is the traditional space, in which generations create meanings and adults prefigure the future. Despite the idea of liquid modernity, which dominates our existence, we are convinced that we inherit meaningful testimonies of schools born in the spirit of the Reform from the pedagogic culture of the last two centuries. Schools, such as Dalton, Jena Plan, Decroly and Freinet, are still alive and bringing us a new message of citizenship education coherent with the impulse of their founders. Following our field study to investigate the reality of the Schools of Method in the areas of the Flanders and Brussels we were able to draw a solid concept of community. In the 500th anniversary of the Reformation, we assume that the modern western culture reaches its task to convert the dispute into tolerance. Citizenship education wishes to overcome any separations and indicates the road to peace and harmony. It is not by chance that Reform Schools are now reaffirming the original impulse. They are transforming the contradictions of our postmodern society into the management of daily education. Headmasters and teachers are seriously opting for movement and variety of the curriculum against school stereotypes of the disciplines. Children become protagonists of the reformation, using the methodology of dialogue, development and discovery. Teachers and parents appear to be fundamental parts of the process, and learning democracy in school begins with the practice of a council of pupils: discussing, deciding, doing. The external world actively enters schools to shape life. History is composed of the biographies of senior citizens, mainly grandfathers, and languages are matter of pride for children from families with migrant backgrounds.

Abstract:

A partir do final da década de 1940 do século XX, a prosa moderna brasileira foi impulsionada por um grupo de escritores que começava a definir o núcleo da ficção curta urbana. Como fruto desse momento, o conto se firma e amplia seus universos conteudísticos, visitando desde temáticas urbanas até os temas regionalistas, do relato documental às investidas intimistas. Dentre as temáticas urbanas e coletivas destacamos a velhice. Essa temática está presente nas narrativas de vários representantes da linha média que caracterizou a ficção brasileira dos anos de 1950 até essas primeiras décadas do século XXI. Das trinta histórias que constituem A guerra conjugal (1969) do contista curitibano Dalton Trevisan, algumas trazem protagonistas na velhice, expondo-as em uma fase do casamento na qual a solidão se instala incisiva e seca. Se em outras narrativas o malogro do casamento é espicaçado pelas ironias constantes, nos enredos em que a velhice é temática central o silêncio predomina como significado maior do distanciamento dos casais. Em "Batalha de bilhetes", a temática da velhice é problematizada através dos personagens protagonistas João e Maria. O conto joga alternadamente com a voz do narrador, que introduz o cenário e descreve as ações das personagens; com o diálogo entre eles, curto e estéril, sugerindo a falta de comunicação; e com a linguagem dos bilhetes, elemento primordial para nossos comentários e, como o próprio título incita, "instrumento bélico" usado pelos personagens. Neste artigo procuramos analisar as marcas que diferenciam as perspectivas adotadas e como a distância do discurso constrói a imagem da velhice isolada do casal. Para a leitura utilizaremos Bosi (1988) sobre a velhice e na análise do plano do enunciado e do plano da enunciação.

Abstract:

Studies were conducted to evaluate the efficiency of cationic polymers as a suitable replacement of metal salts for the treatment of a local tannery wastewater. Eleven cationic polymers of varying molecular weights (MW) and charge densities (CD) were examined using jar test apparatus. Three cationic polymers: one with MW of 4 million Dalton and CD of 55%; second with MW of 6 million Dalton and CD of 40%; and the third with MW of 8 million Dalton and CD of 40% were found suitable for tannery wastewater treatment at an optimum dose of 20 mg/L for each. Percentage removals with these three cationic polymers for turbidity, total suspended solids (TSS), total chemical oxygen demand (TCOD) and chromium lied in a range of 91–95%, 69–83%, 25–29% and 96–97%, respectively with respect to plain settled wastewater. The cost of the most suitable cationic polymer C-496 at its optimum dose was $0.09 per cubic metre of wastewater and sludge production was 35 mL/L. The results demonstrated that treatment of tannery wastewater with cationic polymers is a viable and economical option when compared with metal salts.

Abstract:

Two cDNAs specific for P450 genes, CYP6AE28 and CYP6AE30, have been isolated from the rice leaf folder Cnaphalocrocis medinalis Guenée (Lepidoptera: Pyralidae). Both cDNApredicted proteins have 504 amino acid residues in length, but with molecular masses of 60177 Dalton for CYP6AE28 and 60020 Dalton for CYP6AE30, and theoretical pI values of 8.49 for CYP6AE28 and 8.56 for CYP6AE30, respectively. Both putative proteins contain the conserved structural and functional domains characteristic of all CYP6 members. CYP6AE28 and CYP6AE30 show 52% amino acid identity to each other; both of them have 49 - 56% identities with CYP6AE1, Cyp6ae12, and CYP6AE14. Phylogenetic analysis showed that the two P450s are grouped in the lineage containing some of the CYP6AE members, CYP6B P450s and CYP321A1. The transcripts of CYP6AE28 and CYP6AE30 were found to be induced in response to TKM-6, a rice variety with high resistance to C. medinalis. The results suggest that the two P450s may play important roles in adaptation to the host plant rice. This is the first report of P450 genes cloned in C. medinalis

Abstract:

This paper presents a case study of a natural gas production site covering various technical issues related to selection of an appropriate Reverse Osmosis (RO) system. The long-term field experience indicates the necessity of the selection of appropriate pretreatment systems for fouling-free RO operational conditions. The produced water has a variety of impurities such as oil and grease, process chemicals used for corrosion and scaling control, and dehydration of natural gas, etc. This situation leads to a complicated and extremely difficult task for a membrane specialist to design RO systems, especially the pre-treatment section. Here as part of the pretreatment selection, two types of UF membrane modules viz. spiral wound and hollow fibre, with MWCO of 8000 and 50,000 Dalton respectively, were tested in parallel with NF membranes of the spiral wound type with MWCO 200 Dalton. The UF permeate is used as feed for RO compatibility testing. Both configurations of UF failed to be compatible, due to irreversible fouling of the RO membrane. The NF membrane, however, showed interesting results, due to membrane stability in terms of cleaning and fouling. The NF plant with 50% capacity gave a recovery of 75% and the RO plant gave a recovery of 60% versus the expected 92–95%. The long-term tests have indicated that the reminder of the membranes could be installed to achieve full capacity of the plant. This study also demonstrates the importance of selection of proper pre-treatment set-up for the RO system design.

Abstract:

This research forms part of our ongoing study to elucidate cell wall biosynthesis in red microalgae. Cell wall formation during the cell cycle of the red microalga Rhodella reticulata was followed in cultures synchronized by a regime of dark (12 h), light (12 h), and dilution of the culture thereafter to 1–1.5 × 106cells/ml. Under these conditions, cell number doubled after 24 h, DNA replication occurred between the 6th and 12th hours, and cell division took place between the 8th and 14th hours of the cycle. Cell wall constituents increased only during the light hours, peaking as follows: sulfur at the 2nd hour, protein at the 11th hour, and the various sugars (each at different times) between the 6th and 12th hours of the cycle. Since xylose predominated from the beginning of the cycle, it appears that this sugar was produced first and formed the basic polymer skeleton to which other sugars were attached. Two polymers were produced during the cycle, their sizes (as determined by gel filtration) being 0.5 × 106 and 1.15 × 106 daltons. It thus seems likely that the smaller 0.5 × 106 dalton polymers are produced inside the cells and then excreted into the medium, where they are further polymerized to produce the final-size polymers. The herbicide 2,6-dichlorobenzonitrile (DCB), an inhibitor of cellulose biosynthesis, was previously found to inhibit cell wall formation in red microalgae. When it was added to the cultures at the beginning or at the end of the cycle, no inhibition in cell division was detected, but when it was added at the 8th hour, cell division was significantly inhibited (38%), resulting in an increase in mean cell volume. Addition of DCB did not affect DNA replication or cell wall polysaccharide content or composition, as measured after 24 h of the cycle. It seems that DCB affects an inhibitory phase in cell division and that this inhibition is not necessarily coupled with its inhibition of formation of the sulfated polysaccharide.

Abstract:

In order to adapt to the particularity of pedestrian crossing of universitys passageway, as well as relief the conflict between pedestrians and vehicles, the pedestrian crossing characteristics and crossing facilities were studied. Taking Huanghe road segment near to the main entrance of Dalian Jiaotong University as the investigation object, the pedestrian crossing and vehicle operating characteristics were investigated. By the method of mathematical statistics, the pedestrian crossing characteristics at peak and off-peak period were compared and analyzed. Taking Dalian Jiaotong University as an example, based on the particularity of universitys pedestrian crossing, the design plan of pedestrian crossing facilities was proposed. The research shows that, there is an obvious time distribution characteristic in universitys pedestrian crossing. It is necessary to considerate this characteristic and security to plan pedestrian crossing facilities.

Abstract:

Cauliflower mosaic virus (CaMV), the type member of the Caulimovirus family, is one of the most extensively studied plant viruses since it was one of the first plant viruses shown to encapsidate a genome of double stranded DNA. This virus has served as a model system for studying plant gene organization, expression and replication and is potentially useful as a gene vector for the genetic manipulation of higher plants. Despite being well characterized in terms of its molecular biology, little is known about the structure, organization and assembly of mature CaMV virions.CaMV virions have a molecular mass of ˜22.8x106 daltons and a sedimentation coefficient of 208S.2 In negatively-stained samples, the diameter of the virus was determined to be 50.3±1.4 nm. The capsid consists of multiple copies of a single, phosphorylated polypeptide (37-42 kDa) which is presumed to be post-translationally modified from the 58kDa primary product of gene IV. The sizes of the virion and mass of the capsid protein indicate that there may be 420 copies of the polypeptide, arranged with T=7 icosahedral lattice symmetry, although no direct evidence exists to support this model. Projected images of CaMV particles, examined by conventional electron microscopy procedures, are difficult to interpret since the details are relatively smooth and featureless. The organization of the circular doubled-stranded DNA molecule (˜4.9xl06 daltons) is unknown: neutron diffraction experiments indicate that it is mainly confined to the region between radii 15.0-21.5 nm. The current study is aimed at obtaining a reliable three-dimensional structural determination of CaMV by examining purified virus samples using recently developed cryo-electron microscopy techniques and image analysis procedures.

Da Lian gym is a typical elliptical inclined mega-grid suspend-dome structure. Its complex structure form makes the prestressing construction more difficulty, and it is necessary to make a reasonable choice of construction scheme. In the paper, the summary about traditional prestressing construction schemes is made, and the construction schemes of radial cable tension and strut lifting were compared with construction simulation technology and tensile test. the results indicates that both methods can achieve the prestress construction of the structure, while more difficulties were contained in strut lifting method, therefore construction schemes of radial cable tension was suggested in actual construction. The research can provide theoretical basis for the structure’s prestressed construction plan, and also provide reference for similar projects.

Abstract:

The status of archaeological research is summarized since the publication of Archaeology of the Central Mississippi Valley in 1983. Extensive research dealing with the Paleoindian period and the Pleistocene-Holocene transition has been completed. Fluted points have been found in association with the remains of megafauna, remains of a Paleolama date the extinction of megafauna in the region, and human bone has been identified from the Dalton cemetery at the Sloan site. Plant domestication is believed to have been initiated between 3000–2000 B.C., although corn agriculture is not seen until the Mississippian developments of the ninth century A.D. The route of the 1541–42 DeSoto expedition through the area and associated archaeology has been refined. Extensive work has also been done with Colonial Period sites, especially those of the seventeenth century. New GIS mapping techniques and microwear analyses are enhancing current interpretations of regional archaeology.

Abstract:

Previous studies of Ganoderma lucidum have focused on its medicinal applications. Limited information is available about its antibacterial activity against plant pathogens. Thus, the goal of this study was to purify and characterize the antibacterial activity against plant pathogenic bacteria from culture fluids of G. lucidum. The nature of the bioactive components was determined using heat boiling, organic solvents, dialysis tubing, gel exclusion chromatography (GEC), proteinase sensitivity, HPLC, HPLC-APCI-MS, and GC-MS. The bioactive compounds were neither lipid, based on their solubility, nor proteic in nature, based on proteinase digestion and heat stability. The putative-bioactive polysaccharides have molecular weights that range from 3500 to 4500 Daltons as determined by dialysis tubing, GEC and APCI-MS analysis. The composition of the antibacterial compounds was determined by GC-MS. This is the first report of small polysaccharides produced by G. lucidum with activity against bacterial plant pathogens.

Abstract:

Pretreating cotton seeds with selected herbicide markedly increased cotton resistance to vascular wilt caused by Verticillium albo-atrum. The present investigation studied the mechanism of resistance to V. albo-atrum induced by some herbicides in susceptible cotton plants. The three herbicides tested repressed mycelial growth. Prometryn and dalapon caused a marked reduction in the appearance of Verticillium wilt disease and were the most effective in controlling the disease. Phytoalexin (gossypol) production was greatly increased in herbicide-treated inoculated cotton plants. The level of gossypol was higher in the root than stem. Maximum production of gossypol was achieved in cotton plants treated with the herbicides prometryn and dalapon and inoculated with fungal spores but it was not present in uninoculated control plants. Key words: cotton, Verticillium albo-atrum, herbicides, phytoalexin, disease resistance.

Abstract:

Contemporary changes in the whole system of education and training require the teacher to be a person of trust, educator, counselor, friend, organizer, coordinator, associate, innovator, assessor, mentor; in another words, a contemporary and modern person. In the modern school (even more in the future) the role of the teacher is far wider. He needs to be active in school, outside of school, within free activities, as well as cultural and public activities of the school. A good teacher does not resist the influence of a student, because his or her extremely responsible role can be successfully achieved, if they work well with them. To cooperate in this context does not mean that only the teacher listens to the student's suggestions, although that is also very important, but cooperating means accepting the student's proposal, if they are objectively acceptable or explain why a particular proposal cannot be realized. It is not possible to work well and democratically in the classroom if the student's influence is not accepted. If the teacher's behavior and style of work are not necessarily limited to the work and behavior of a student, then there is no interaction, and the teaching process must be an interaction. Changes in the society affect school changes, and changes in school play the most important role in changing the position of the teacher and his role and the style of work in the teaching process. The survival and future of the school is reflected in its educational role. In order for a teacher to be an educator, to fulfill his or her educational role, he/she must love or sympathize with the kids, respect their opinion, encourage them to achieve good results, but also to share with them possible misunderstandings and failures. The success and superiority of teachers as educators depends more on the quality of the relationships established, and less on the knowledge of the subject being taught, even though this component cannot be ignored.Thanks to the good work style, the teacher can achieve better results in the educational process. This does not only apply to the choice of working methods, but the style of work is reflected in the overall individual pedagogical practice of teachers. In the style of work the teacher expresses his / her independence, creativity, initiative, democracy or authoritarianism, lack of competence, irresponsibility. In modern school, children need to play a central role, and the school should become a place where they are exploring, examining, solving problems and to lead them to a deliberate dialogue. Students need to experience the school as a place where the child develops in cognitive, emotional and social sense, and where the child's motivation to work is at a high level. Active teaching (active learning, active school) is an original pedagogical creation based on theoretical settings and practical attempts of transformation of a traditional school into an active school, i.e. a school in which both the student and the teacher have an active role. Thinking about active learning is inspired by the works of Kerenstahner (work school), Laj, Dekrol (school for life and life), Klapard (school by sea), Djuij (pragmatic conception), Montesori, Fereira (active school) Frenoa, Dalton plan, Vinteka-plan, etc. The summary of their research endeavors and theoretical endeavors, aimed at constituting an active school, is the following Piaget's statement, which for active teaching has an absolute programmatic meaning: "In one of the words, the basic principle of active methods should be inspired by the history of science and can be expressed in the following way: Something means self-discovery or reconstruction through re-discovery and it is necessary to adhere to that principle if in the future we want to shape people who will be capable of producing and creating and not just repeating what already exists. " To reach a comprehensive and precise concept of active learning, the activity of children in the learning process is of paramount importance. From the cited Piaget's theoretical point of view, for the active learning, three are very important elements: An important component of activity as an internal (mental) activity is defined: this activity (or at least one of its, important for school learning) is the passage through the intellectual processes through which it came to science when it came to discoveries and finds. So, the student briefly reconstructs these thought processes; The object of thought activities is not only their own immediate experience but also the intellectual content of certain scientific disciplines; The basic goals of school learning through active methods are: a good understanding of what is in science but also the adoption of intellectual arts for productive and creative activities. The traditional school works on pre-defined plans and programs and the goal of the curriculum is to adopt the program. The basic teaching method is the lecture (verbal transfer of knowledge) with the occasional use of teaching resources. The student has a mostly passive role of a listener who has to understand, remember and reproduce the compulsory material. Evaluation, whether verbally or in writing, consists in verifying the measure in which the required degree has been adopted. Learning motives are largely external to nature (appreciation, praise, reward, punishment ...) In a traditional school, the child is looked upon as a pupil, that is to one who should, with understanding, repeat the course more profoundly. An active school is more focused on a young man who is treated as a whole person whose intellectual potentials need to engage more in the teaching process. The active school is based on compulsory education standards based on which the orientation plans and work programs are designed. Such access also implies a part of teaching that is flexible and varies depending on the student's interest. Learning motivation is personal (internal). In teaching, active learning methods are based on work and intellectual engagement of students and research activities. The goal of an active school is not only the adoption of a curriculum, but also the versatile personality development of students. The active school evaluates not only the degree of competence of the knowledge defined by the educational standards, but also the progress of the children in comparison with the initial situation, the motivation and interest of the students for work and activity, the development of the personality and the satisfaction of the student's teaching that is realized.

Abstract:

Twenty herbicides were applied to a rangeland pasture in the Post Oak Savannah Resource Area of Texas in April 1978 and May 1979. At time of treatment, total vegetation cover was 88 to 100%, with 36% grasses and 52 to 64% broadleaf cover. From May 31 through September, total, grass, and broadleaf covers were 89 to 100, 51 to 65, and 27 to 44%, respectively. One to 2 months after treatment, grass cover generally increased except where certain herbicides, particularly bromacil (5-bromo-3-sec-butyl-6-methyluracil), dalapon (2,2-dichloropropionic acid), glyphosate [N-(phosphonomethyl)glycine], or hexazinone [3-cyclohexyl-6-(dimethylamino)-1-methyl-1,3,5-triazine-2,4 (1H, 3H)-dione] had been applied. By September or October in the year of application only dalapon consistently reduced grass cover. In the year following treatment, grass cover was still reduced on the dalapon-treated plots. Most herbicides reduced broadleaf cover in the year of treatment. Broadleaf cover returned most rapidly to those areas treated with dalapon. During the year following treatment, broadleaf cover remained low on plots treated with picloram (4-amino-3,5,6-trichloropicolinic acid), 2,4,5-T [(2,4,5-trichlorophenoxy)acetic acid], and picloram + 2,4,5-T. For plots treated in 1978, the grass and broadleaf standing-crop weights of untreated plots were 490 and 450 kg/ha, respectively, in October 1978, and 2707 and 1033 kg/ha in October 1979. In 1978, grass weight increased with several herbicide treatments whereas only dalapon increased the broadleaf weight. For plots treated in May 1979 and harvested in September 1979, grass and broadleaf standing-crop weights of untreated plots were 2629 and 607 kg/ha, respectively.

Abstract:

The objective of this study is to investigate how the molecular weight distribution of the organic substances affects their treatment efficiencies and the reduction of disinfection by-products (DBPs) in the various unit operations of a full-scale water treatment plant. The results indicate that the membrane with a smaller molecular weight cut-off is more effective for removing the organic substances and its associated water quality parameters from the raw water. For example, using the membrane with a molecular weight cut-off of 0.5 K (500 daltons), the removal efficiency of DOC from the raw water sample can be as high as 88%. Removal efficiencies of other water quality parameters such as UV254 absorbance, THMFP and AOXFP are generally between 65–69%. When undergoing the various unit operations in the conventional water treatment plant, most organic substances are removed in the coagulation process followed by sedimentation.

Full text

Abstract:

Since 1999 the Mery-sur-Oise plant has operated using two processes in parallel: one, a membrane process using nanofiltration, and the other, a conventional biological process. For operational flexibility, it is desired to be able to transfer some of the sand-filtered ozonated water from the biological process to the membranes. Before carrying out this transfer, it was important to assess the role of ozonation on membrane fouling, by comparing the effects of ozonated water (SFOW) with non-ozonated water (SFW). Tests were performed, in spring and fall 2001, in a pilot unit comprising two nanofiltration lines in parallel. The first test emphasized the essential role of the pre-filter placed upstream of the membranes. This latter - supplied with ozonated water – released particles when saturated, linked to changes in the feed water quality. Despite very frequent pre-filter replacements, fouling proved to be greater for the membranes supplied by ozonated water. Even though the silt density index and total cell counts levels of SFOW were lower than SFW, ozonated water could increase membrane fouling. The action of ozone on the nature of organic matter appeared to be the main cause. Ozone modified the composition of natural organic matter, on one hand by reducing the hydrophobic fraction in favour of the hydrophilic fraction, which is harder for the membrane NF 200B to reject, and on the other hand by acting on the lyses of algal cells and the release of extracellular organic matter. The membrane autopsies confirmed that the deposit is essentially composed of organic matter. Images taken with a scanning electron microscope showed a more significant deposit for membranes fouled with SFOW. For the membrane fouled in spring, the images also revealed the presence of algae; for some, cells were lysed upon ozonation. HPSEC-UVA-DOC enabled the types of molecules to be identified according to size. Humic substances (1,000 to 5,000 daltons) and other low molecular weight components (400 to 600 daltons) represented a minor part of the fouling material with the major components being proteins (21,000 to 24,000 daltons). Also, humic substances were relatively more abundant in the membrane fouled with ozonated water in spring.

Abstract:

Garlic mustard (Alliaria officinalis) is a common weed species associated with woodland borders, hedge rows, and suburban gardens. Garlic mustard plants expressing foliar symptoms of leaf mosaic and vein banding were collected from Franklin and Cuyahoga counties in Ohio. Analysis of symptomatic tissue using viral-associated double-stranded RNA (dsRNA) analysis on 5% polyacrylamide gels and stained with ethidium bromide resulted in the production of a banding profile (four dsRNA bands with molecular weights of 2.6, 2.0, 1.5, and 0.7 × 106 daltons) similar to that of Cucumber mosaic virus (CMV) (1). Symptomatic tissue suspected of being infected with CMV was analyzed with an indirect enzyme-linked immunosorbent assay (iELISA) employing commercially produced antiserum (Agdia Inc.) against the common strain of CMV antiserum confirmed the presence of CMV. Nonsymptomatic tissue reacted negatively to CMV. This is the first report of CMV in garlic mustard in Ohio. Due to the extensive range of this weed and the wide host range of CMV in ornamental and food-plant species, garlic mustard could serve as an alternate host for CMV in many commercially important plant species.

Sodium carbonate perhydrate, Na2CO3·1.5H2O2, commonly known as sodium percarbonate, has been structurally characterized at temperatures ranging from 293 down to 100 K. As the temperature drops, there is a reversible phase change between 250 and 240 K, in which the crystallographic mirror plane of the room-temperature space group, Cmca, is lost, transforming it to Pbca. This transformation is accompanied by a reversal in the expansion coefficient of cell side b, which, like the other two sides, initially contracts on cooling. The two crystallographically independent hydrogen peroxide sites undergo the largest change, where the disorder seen at room temperature gradually diminishes and is almost completely absent at 100 K, thus indicating dynamic rather than static disorder. It is noteworthy that, despite Cmca being the preferred room-temperature space group in the current work, two previous single-crystal studies rejected this space group in favour of non-centrosymmetric Aba2 [Carrondo et al. (1977). J. Chem. Soc. Dalton Trans. pp. 2323–2331; Adams & Pritchard (1977). Acta Cryst. B33, 3650–3653]. A re-evaluation of these determinations indicates that they are identical to the current structure and should be re-assigned to Cmca.
