Abstract (sommario):

ABSTRACT Highly purified subunit vaccines require potent adjuvants in order to elicit optimal immune responses. In a previous phase I trial, an alum formulation of ICC-1132, a malaria vaccine candidate comprising hepatitis B core (HBc) virus-like particle containing Plasmodium falciparum circumsporozoite (CS) protein epitopes, was shown to elicit Plasmodium falciparum-specific antibody and cellular responses. The present study was designed as a single-blind, escalating-dose phase I trial to evaluate the safety and immunogenicity of single intramuscular doses of ICC-1132 formulated in the more potent water-in-oil adjuvant Montanide ISA 720 (ICC-1132/ISA 720). The vaccine was safe and well tolerated, with transient injection site pain as the most frequent complaint. All vaccinees that received either 20 μg or 50 μg of ICC-1132/ISA 720 developed antiimmunogen and anti-HBc antibodies. The majority of volunteers in these two groups developed sporozoite-specific antibodies, predominantly of opsonizing immunoglobulin G subtypes. Peak titers and persistence of parasite-specific antibody following a single injection of the ISA 720 formulated vaccine were comparable to those obtained following two to three immunizations with alum-adsorbed ICC-1132. Peripheral blood mononuclear cells of ICC-1132/ISA 720 vaccinees proliferated and released cytokines (interleukin 2 and gamma interferon) when stimulated with recombinant P. falciparum CS protein, and CS-specific CD4+ T-cell lines were established from volunteers with high levels of antibodies to the repeat region. The promising results obtained with a single dose of ICC-1132 formulated in Montanide ISA 720 encourage further clinical development of this malaria vaccine candidate.

Abstract (sommario):

The liquid shampoo is a product that is generally used to clean hair and scalp. The additional active ingredient used in the liquid shampoo is neem leaves which contain polyphenols that have antibacterial effects. Neem leaves extract was made by hot infusion method with coconut oil as a solvent. The purposes of this research were to find the best concentration of neem leaves infused oil for liquid shampoo material and compare the qualities of liquid shampoo with Indonesian National Standard (SNI) of Shampoo 06-2692-1992. The method of this research was a laboratory experiment with descriptive analysis. This research was conducted in five treatments. Concentration neem leaves infused oil for liquid shampoo materials were ratio between coconut oil and neem leaves in sample A = 720:0 (w/w); B = 720:22,5 (w/w); C = 720:30 (w/w); D = 720:45 (w/w); and E = 720:90 (w/w). The result showed that all of the shampoos met the SNI of Shampoo 06-2692-1992 according to organoleptic, moisture content, and pH. The best shampoo based on organoleptic observation was shampoo C (720:30 (w/w)) with a hedonic percentage of 40%, moisture content of 69.89%, pH 7.03, and specific gravity of 1.0223 g/g. The highest antibacterial activity against S. aureus was shampoo E (720:90 (w/w)) with an inhibition zone diameter was 9.5 mm. Shampoo with the highest antibacterial activity resulted from the highest addition of coconut oils infused Neem leaves. It proved that neem leaves were effective as an additive in making shampoo to boost its antimicrobial properties.

Abstract (sommario):

O objetivo deste estudo foi verificar o sinergismo ou antagonismo de glyphosate com e sem a mistura de saflufenacil no controle de B. decumbens. Foram avaliados no estudo os seguintes tratamentos: glyphosate (1.080), glyphosate + saflufenacil + Dash (1.080 + 24,5 + 0,5% v/v), glyphosate + 2,4 D (1.080 + 720); glyphosate (1.440); glyphosate + saflufenacil + Dash (1.440 + 24,5 + 0,5% v/v); glyphosate + 2,4 D (1.440 + 720); saflufenacil + Dash (24,5 + 0,5 v/v); 2,4 D (720), doses em g i.a./e.a. ha-1. A eficiência de controle de B. decumbens foi avaliada em diversos períodos: 3, 7, 14, 21, 28, 35, 42 e 49 dias após a aplicação (DAA), com base nos sintomas de fitointoxicação, utilizando-se a escala de 0% a 100%. Os resultados foram submetidos à análise de variância pelo teste F e as médias comparadas pelo teste Tukey ao nível de 5% de probabilidade. O herbicida glyphosate aplicado de forma isolada nas duas doses testadas, ou em mistura com saflufenacil, proporcionou um excelente controle das plantas de B. decumbens já a partir dos 14 dias. Os herbicidas saflufenacil e 2,4-D quando aplicados isoladamente sem a presença do herbicida glyphosate mostraram-se ineficientes no controle das plantas. O controle das plantas de braquiária proporcionado pelas misturas de glyphosate com 2,4-D e saflufenacil foi semelhante ao da aplicação isolada de glyphosate. As misturas não apresentaram sinergismo ou antagonismo sobre o controle das plantas de B. decumbens.

Abstract (sommario):

A eficiência do glyphosate no controle de Brachiaria brizantha cv. Marandu em áreas de cultivo do Tifton 85 foi avaliada utilizando o delineamento experimental em blocos casualizados, com oito doses de glyphosate (0, 90, 180, 360, 720, 1.080, 1.440 e 1.800 g ha-1), e quatro repetições. Cada parcela foi constituída de um vaso com duas plantas de B. brizantha cv. Marandu e duas plantas de Tifton-85. A aplicação do herbicida foi feita quando as plantas de B. brizantha apresentavam cerca de 40 cm de altura. O nível de intoxicação nas plantas de Tifton 85 e a eficiência do herbicida no controle de B. brizantha foram avaliados aos 15, 30 e 60 dias após aplicação (DAA). Aos 60 DAA, as plantas foram colhidas ao nível do solo e secas em estufa. A rebrota foi avaliada, do mesmo modo, aos 60 dias após o corte (DAC). Obeservou-se controle superior a 90% de B. brizantha, a partir da dose de 738,28 g ha-1 de glyphosate, enquanto a intoxicação para as plantas de Tifton 85 foi de apenas 12,05. Aos 60 DAA, houve redução na produção de massa seca de braquiária a partir da dose de 90 g ha-1. Doses superiores a 720 g ha-1 diminuíram o crescimento e desenvolvimento do Tifton 85, afetando sua produção, sem, no entanto, ocasionar a morte das plantas. Os resultados evidenciam boa tolerância do Tifton 85 até a dose de 720 g ha-1 de glyphosate.

Abstract (sommario):

Three different species of Snails, B. Alexandria, M. tuberculata and P. acuta are selected from Lake Tauorgha. Libya. The results show that physa acute is more adaptive for life in captivity when Kept in aquaria for a period of time from three months to one year. M. tuberculata snails are able to reproduce but with a loss degree than P. acuta, when water from Lake Tauorgha. Also, tap water is added to the aquaria, P. acute continued to live in the artificial environment for less than three months. P. acute snails are the most resistant to the artificial conditions with more observable reproductive ability while M. tuberculata has less ability than P. acute but B. alexandrina survived those artificial environment conditions for a few days. The present study revealed that of (720) B. alexandria snails (720) with different shell sizes (15.13%) were found naturally infected with Fasciola (cercaria) and S. mansoni (cercaria) (p< 0.01).

Abstract (sommario):

A structural phase transition study of Ba2YCu3O6+x (x = 0 to 1) has been conducted on a series of 13 quenched samples. These samples were prepared from an orthorhombic material by annealing at temperatures from 400 to 1000 °C in air, followed by rapid quenching. All quenchings were performed by using a liquid-nitrogen-cooled copper cold well with a continuous flow of cooled helium gas. Various measurements including x-ray diffraction, thermogravimetric analysis, Meissner effect, and scanning electron microscopy were carried out in order to correlate the nature of the phase transition with erystallographic data, superconductivity, and annealing temperature. The phase transition from Ba2YCu3,O7 to Ba2YCu3O6 appears to involve two orthorhombic regions: region A with a <b ≈ c/3 below approximately 600 °C and region B with cell parameters of a < b < c/3 from & 600 to 708–720 °C. The transformation from orthorhombic to tetragonal takes place in the temperature range of 708–720 °C. This transition appears to be a second-order, order-disorder type.

Abstract (sommario):

Para avaliar doses do herbicida glyphosate, isolado ou misturado com 2,4-D, na dessecação do campo nativo para semeadura direta de soja, foi conduzido um experimento no compus da UFSM. Os tratamentos foram: glyphosate a 360, 720 e 1080g ha-1 de equivalente ácido, isolado ou em mistura com 200g ha-1 de 2,4-D éster, aspergidos em dois volumes de calda (50 e 200l ha-1), além de testemunha sem controle. A aspersão dos herbicidas ocorreu em 30/10/95 e a semeadura da soja em 27/12/95. Das 57 espécies presentes no campo nativo, as principais foram: Paspalum notatum var. notatum biótipos "C" e "D", Vernonia polyanthes, Vernonia nudiflora, Eryngium horridum e Baccharis trimera. Os resultados mostram que o uso de 2,4-D e a redução do volume de calda de 200 para 50l ha-1 não melhoraram a eficácia de controle do glyphosate, que mostrou controle geral de 48, 73 e 90% para as doses de 360, 720 e 1080g ha-1. O glyphosate mostrou controle ineficiente de V. polyanthes, V. nudiflora e E. horridum, independente da dose ou mistura com 2,4-D, sendo eficiente para B. trimera à 720 e 1080g ha-1. Houve controle do Paspalum de 54, 79 e 93% para o glyphosate à 360, 720 e 1080g ha-1 . O rendimento médio de grãos de soja foi de 1762, 2502, 2690 e 2793 kg ha-1, para testemunha e glyphosate a 360, 720 e 1080g ha-1. Conclui-se que, para semeadura direta de soja sobre campo nativo, a dose de 1080g ha-1 de glyphosate é adequada.

Abstract (sommario):

Abstract Background: The objective of this prospective study was to assess the medical and economic long-term effects of using B-type natriuretic peptide (BNP) concentrations in the management of patients with acute dyspnea. Methods: We performed follow-up analysis of the B-Type Natriuretic Peptide for Acute Shortness of Breath Evaluation, a randomized study including 452 patients who presented to the emergency department with acute dyspnea. Participants were randomly assigned to a diagnostic strategy involving the rapid measurement of BNP concentrations (n = 225) or standard assessment (n = 227). Mortality was assessed at 720 days, morbidity and economic data at 360 days. Results: BNP testing induced several important changes in initial patient management, including a reduction in the initial hospital admission rate, the use of intensive care, and initial time to discharge. At 720 days, 172 deaths had occurred. Cumulative all-cause 720-day mortality was not different between the BNP group (37%) and the control group (36%, P = 0.6). Morbidity as reflected by days spent in-hospital at 360 days was significantly lower in the BNP group [median 12 days ([interquartile range 2–28 days)] compared with the control group [median 16 (7–32)] days, P = 0.025]. Functional status was similar in both groups. Economic outcome as quantified by total treatment cost at 360 days was significantly improved in the BNP group (mean $10 144 vs $12 748 in the control group, P = 0.008). Conclusions: Rapid BNP testing in patients with acute dyspnea has no effect on long-term mortality. However, morbidity as quantified by days spent in-hospital and economic outcome are still improved at 360 days.

Abstract (sommario):

The attitude of the early Islamic state towards figurative representations is often cited as a source contributing to the establishment of officially-supported iconoclasm within the Byzantine Empire in A.D. 726. Islam has generally adopted a position opposed to the representational in secular art, and the exclusion of all figurative motifs from Islamic religious art is clear from the first, yet this attitude is not necessarily to be regarded as intrinsically iconoclastic in the true sense of the word; indeed, outside Arabia itself, the only evidence of iconoclasm until the fall of the Umayyad Caliphate in 132/750 is confined to the well-known attack on images and statues carried out on the orders of Yazīd II. b. ‘Abd al-Malik (101–105/720–724). This much discussed outbreak of iconoclasm is well documented by Islamic and Christian sources, but the very fact that it is so specifically associated with Yazīd's Caliphate suggests that it was considered unusual at the time. Although Christian sources carefully record the difficulties of their communities under the Umayyads, the absence of references to image-breaking under Caliphs before Yazīd implies that his action was a rarity worthy of comment: under normal circumstances, it would seem the Muslims left the Christians to use icons and representations or not, as they wished.

Abstract (sommario):

The effect of four application rates of glyphosate (Roundup, 360 g a.i./l) - 180; 360; 720 and 1440 g a.i./ha on the survival, dynamics of growth, and accumulation of fresh biomass in g per plant was studied on eight newly-developed Bulgarian lines, varieties and candidate varieties of soybean bred by different methods under greenhouse conditions. The objective of this study was to determine and compare the sensitivities of different soybean genotypes to glyphosate. The studied soybean genotypes showed different levels of glyphosate sensitivity due to their genetic differences. Glyphosate rates of 180, 360, 720 and 1440 g a.i./ha, applied at the stage of three trifoliate leaves (V4) of soybean had effect on the survival of the studied genotypes and can be presented conditionally in the following order: H (40.6%) < G (40.7%) < D (51.3%) < C (52.6%) < F (58.9%) < E (60.5%) < B (62.0%) < A (65.3%). The depression coefficients (B) of the studied characteristics depended mainly on soybean genotypes and the applied herbicide rates. The tested glyphosate rates showed a high (GI 26.5-51.6%) to relatively low degree of toxicity (GI 16.0-18.7%) in the studied soybean genotypes.

Condições meteorológicas predominantes em diferentes horários de aplicação podem interferir na eficácia de herbicidas. O objetivo desta pesquisa foi determinar o horário mais adequado para a aplicação de dicamba e associações visando a otimização do controle de Bidens pilosa. O experimento foi realizado em casa-de-vegetação, no delineamento inteiramente casualizado, com 4 repetições. Os tratamentos foram dispostos em esquema fatorial (14 x 4) +1, sendo 14 tratamentos com herbicidas e suas associações e quatro horários de aplicação, mais a testemunha sem herbicida. Os herbicidas dicamba (480 e 280 g i.a. ha-¹), glufosinato de amônio (600 e 300 g i.a. ha-¹), glifosato (1140 e 720 g i.a. ha-¹) e as combinações de dicamba + glufosinato de amônio (480 + 600, 480 + 300, 280 + 600, 280 + 300 g i.a. ha-¹), dicamba + glifosato (480 + 1140, 480 + 720, 280 + 1140 e 280 + 720 g i.a. ha-¹), além da testemunha, foram aplicados sobre Bidens pilosa as 08:00, 12:00, 17:00 e 21:00 horas. Os resultados evidenciaram que as associações de dicamba com glufosinato de amônio e glifosato foram eficazes no controle de B. pilosa, independentemente do horário de aplicação. O horário de aplicação apresentou maior interferência na eficácia dos herbicidas quando aplicados isoladamente nas menores doses.

Brocchinia verheckeni occurred from the states of Ceará to Sergipe, and B. harasewychi was collected from the states of Pernambuco to Alagoas. Both species are considered endemic to these regions. This is the second record of the genus Brocchinia Jousseaume, 1887 in deep waters off Brazil. Brocchinia harasewychi has a protoconch with 1 ¼ whorls, which is more inflated in comparison to B. verheckeni, the body whorl has 3 spiral cords, the uppermost bordering the suture and the other 2 near mid-whorl. The body whorl of Brocchinia verheckeni has 3 strongly nodulose spiral cords and an outer lip with 5 to 6 internal denticles, while that of B. harasewychi has a smooth outer lip. The genus Gergovia Cossmann, 1899 is recorded for the first time in the Atlantic Ocean with the description of Gergovia petiti n. sp., known only from the oceanic region from Northeast Brazil, occurring from the state of Ceará to the state of Bahia, as well as in the Fernando de Noronha archipelago, probably living in the muddy substrate at depths of between 206 and 720 meters.

Abstract (sommario):

This paper discusses the microstructural changes during hot deformation, mainly dynamic nucleation and growth of a precipitates, occurring in the b metastable titanium alloy Ti-5553 (Ti–5Al–5Mo–5V–3Cr–0.5Fe). The effect of process variables on flow response and microstructure evolution during hot working of the alloy with initial bimodal microstructure was established using isothermal hot-compression tests. Testing was conducted at 4 strain rates between 0.001 and 1 s−1and 5 temperatures between 720 °C and 850 °C, on material with prior b grain size of 450 μm, a nodular size of 3 µm and a known primary a-phase fraction. All flow curves exhibited a peak stress followed by moderate flow softening in the two-phase domain. Flow softening was interpreted in terms of deformation heating and substructure or texture evolutions. The dependence on strain rate and temperature of the kinetics of dynamic a-phase nucleation during straining is complex and appears to be of second-order importance compared to the effects of strain. This suggests that the nucleation and growth of a phase in the temperature range between 720 °C and 990 °C results from a mixed-mode displacive-diffusional transformation, similar to the austenite / ferrite transformation above the Ae3 temperature reported by some authors.

Abstract (sommario):

The nonlinear optical properties of heterocyclic compounds (1-7) were investigated. π-Centers benzo[1,2-b:4,3-b']dithiophene (1) and trithia[5]helicene (5) were studied. Compounds 2-4, 6 and 7 possess either donor-π (D-π) or donor-π-acceptor (D-π-A) structures. The optimized geometry of 7 shows a 3D helical structure. Two-photon absorption cross-sections related to the third-order nonlinear susceptibility were measured using open-aperture Z-scan techniques. Compound 7 has a two-photon absorption cross-section of 103 GM when excited at 720 nm. Important molecular structure-nonlinear optical property relationships are formulated.

Abstract (sommario):

"Panela" is a natural sweetener obtained by concentrating sugar cane juice and handmade in small factories. In the study carried out, the physical and chemical properties of two commercial brands of artisanal granulated panelas and of one made on an experimental level were determined. Three lots of each sample were analyzed. The parameters measured were moisture, a w, protein, ash, minerals, reducing sugars, sucrose, pH, color (L, a and b), insoluble solids (IS), transmittance a 720 nm and filterability. In addition, a qualitative test to detect sulphur dioxide was performed. The parameters with higher variability were moisture (1.66-4.36 g.100 g-1), a w (0.51-0.69), reducing sugars (4.58-11.48 g.100 g-1), pH (5.58-6.90), and color. Potassium was the most abundant mineral (229.52-1027.18 mg.100 g-1). An inverse relationship between IS and transmittance at 720 nm (R² = 0.96) and a direct relationship between IS and ash (R² = 0.94) were found. The sulphur dioxide test was negative for all the samples.

Objetivou-se neste trabalho avaliar a eficácia agronômica e os efeitos fitotóxicos de herbicidas aplicados em pré-plantio no manejo de Euphorbia heterophylla e Bidens pilosa, em sistema de plantio direto da cultura de soja. O experimento foi desenvolvido na safra 2000/2001, na FEP-UNESP, no município de Selvíria-MS. A variedade de soja utilizada foi a 'Conquista', e o delineamento experimental adotado foi o de blocos ao acaso, com sete tratamentos e quatro repetições, com oito linhas da cultura, totalizando 20 m² cada parcela. Os tratamentos foram os seguintes: glyphosate (720 e 960 g ha-1), chlorimuron-ethyl + glyphosate (10 g + 720 e 960 g ha-1), glyphosate + 2,4-D (960 + 868 g ha-1) e testemunhas no mato e no limpo. As aplicações foram realizadas com pulverizador de pressão constante (CO2) de 45 lb pol-2, com barra equipada com quatro bicos do tipo leque Teejet 110.03 XR, espaçados de 0,5 m, e volume de calda de 250 L ha-1. Concluiu-se que os tratamentos testados são eficientes na dessecação de E. heterophylla e B. pilosa e seletivos às plantas de soja. O herbicida chlorimuron-ethyl (10 g ha-1) aplicado juntamente com o glyphosate, no manejo, proporciona ao tratamento um efeito residual significativo para E. heterophylla e B. pilosa, reduzindo a infestação das plantas daninhas durante o ciclo da cultura da soja.

Abstract (sommario):

By using the Olympus GX71 microscope, the effects of Al-5Ti-B addition, holding time and holding temperature on the microstructure of Al-5Cu alloy have been studied, and the influencing rules have been got. The experimental results show that the refinement effect of Al-5Ti-B is very remarkable and the grain sizes of Al-5Cu become small. The optimal parameters are as follows. The refiner addition is 2%-3%, and the holding time is 15 minutes, and the holding temperature is 720°C-740°C. When the 2%-3% Al-5Ti-B refiner is added, the Al3Ti is fine needle shape and the precipitation phase Al2Cu is round flake shape or reticular shape. Simultaneously, the dendrites have minimum spacing, and the microstructure becomes fine and uniform.

Abstract The aim of the study was to assess the distribution of Anaplasma phagocytophilum, Borrelia burgdorferi sensu lato, and Babesia canis in adult females and males of Ixodes ricinus and Dermacentor reticulatus ticks, inhabiting meadows near large forest complexes throughout the Lubelskie Voivodship (eastern region of Poland). Ticks were collected using the flagging method. Among 720 ticks collected, 506 were identified as D. reticulatus, and 214 as I. ricinus. DNA of B. canis and B. burgdorferi s.l. was detected in 21.3% and 0.6% of D. reticulatus ticks, respectively. In I. ricinus ticks, DNA specific to B. burgdorferi s.l. and A. phagocytophilum was detected in 5.6% and 10.3%, respectively. Co-infections of B. burgdorferi s.l. and A. phagocytophilum were found in two I. ricinus ticks. These results indicate that the Lublin region is an area at risk of tick-borne diseases of humans and animals, which must be considered in clinical practice.

Abstract (sommario):

Biomass gasification was separated from catalytic pyrolysis in a two-stage fixed bed reactor with precalcined copper slag catalysts placed in a secondary reactor. The effects of gasification temperature (720-950°C), steam to biomass (S/B) mass ratio (0-2g/g), precalcined copper slag to biomass (C/B) mass ratio (0-2g/g) and copper slag precalcined at different temperatures (800-1000°C) on characteristics of biomass gasification were investigated. The experimental results show that the increase of gasification temperature, S/B mass ratio, C/B mass ratio and precalcination temperature are all favorable for raising gasification efficiency and enhancing the H2 production. With copper slag precalcined at 1000°C for 5 hours as catalyst under the experimental conditions examined, the H2 content, the hydrogen yield, the gas yield and the gasification efficiency reach the maximum of 59.16%, 0.72 Nm3/kg, 1.22 Nm3/kg and 77.56%,respectively.

Abstract (sommario):

We develop the BRST approach to construct the general off-shell local Lorentz covariant cubic interaction vertices for irreducible massless and massive higher spin fields on d-dimensional Minkowski space. We consider two different cases for interacting higher spin fields: with one massive and two massless; two massive, both with coinciding and with different masses and one massless field of spins s1,s2,s3. Unlike the previous results on cubic vertices we extend our earlier result in (Buchbinder, I.L.; et al. Phys. Lett. B 2021, 820, 136470) for massless fields and employ the complete BRST operator, including the trace constraints, which is used to formulate an irreducible representation with definite integer spin. We generalize the cubic vertices proposed for reducible higher spin fields in (Metsaev, R.R. Phys. Lett. B 2013, 720, 237) in the form of multiplicative and non-multiplicative BRST-closed constituents and calculate the new contributions to the vertex, which contains the additional terms with a smaller number of space-time derivatives. We prove that without traceless conditions for the cubic vertices in (Metsaev, R.R. Phys. Lett. B 2013, 720, 237) it is impossible to provide the noncontradictory Lagrangian dynamics and find explicit traceless solution for these vertices. As the examples, we explicitly construct the interacting Lagrangians for the massive spin of the s field and the massless scalars, both with and without auxiliary fields. The interacting models with different combinations of triples higher spin fields: massive spin s with massless scalar and vector fields and with two vector fields; massless helicity λ with massless scalar and massive vector fields; two massive fields of spins s, 0 and massless scalar is also considered.

Abstract (sommario):

Esso/BHPP's West Tuna and Bream B Platforms are the first completed concrete-based platforms in Australia and are Exxon's first designed, built and operated concrete gravity structures (CGSs). Both platforms were towed to location, complete with commissioned topsides facilities, in fourth quarter 1996 and successfully installed in 61 m of water. They will add in excess of 45,000 BOPD (7200 kl/d) of oil production to Bass Strait volumes. West Tuna, with 48 well slots, will be Esso/BHPP's largest and most complex Bass Strait production facility, whereas Bream B will be an 18-slot, unstaffed minimum facility satellite platform with a 720-tonne topsides. By comparison, West Tuna's topsides weigh 7,300 tonnes.Esso/BHPP chose the CGS concept for the two developments following extensive conceptual studies with selected North Sea designers. Because of rising derrick barge day rates in the early 1990s (required for steel pile jacket installations), coupled with the availability of a suitable casting basin near Sydney, the CGS concept was judged economically attractive, with savings estimated at 10 per cent of the total facilities capital expenditure relative to its steel pile jacket alternative.The project saw a number of firsts, including the use of the world's largest land-based crawler cranes to lift and set the completed production modules over 75 m in the air onto the completed CGS structures. CGS fabrication productivity problems were experienced during the early phase of construction reflecting the complex nature of the construction, however implementation of a number of project management initiatives resulted in achievement of world-class productivity by completion of the works.

O objetivo deste trabalho foi verificar a seletividade de herbicidas utilizados em áreas de eucalipto sobreo crescimento de Myracrodruon urundeuva. O experimento foi conduzido em casa de vegetação em duas épocas diferentes (2002 e 2003), em delineamento inteiramente casualizado, arranjado em esquema fatorial (5x4), sendo cinco herbicidas em quatro doses, com seis repetições. Os tratamentos, com as doses, foram: haloxyfop-methyl (0,00, 120, 240 e 480 g ha-1), sulfentrazone (0,00, 300, 600 e 1.200 g ha-1), isoxaflutole (0,00, 150, 300 e 600 g ha-1), oxyfluorfen (0,00, 720, 1.440 e 2.880 g ha-1); e glyphosate (0,00, 720, 1.440 e 2.880 g ha-1). Em ambos os experimentos foram avaliados: efeitos fitotóxicos do produto, número de folíolos, altura de plantas; no segundo, foi feita ainda a análise de clorofila a e b e de carotenóides. O herbicida que apresentou maior fitoxicidade e que comprometeu o desenvolvimento da aroeira foi o glyphosate, sendo, portanto, não recomendado para o controle de invasoras em áreas de plantio de aroeira. Os outros herbicidas não comprometeram o desenvolvimento desta planta, apresentando, por isso, potencial para uso no manejo de plantas daninhas no cultivo desta espécie.

Abstract. A total of 720 newly-hatched Arbor Acres broilers were selected to investigate the effects of fructooligosaccharide (FOS) and B. subtilis on performance and microbial gut concentration in broilers. The result indicated that dietary supplementation with FOS or Bacillus in comparison to an antibiotic had selective effects on increasing caecal concentration of beneficial bacteria such as Lactobacillus and decreasing concentration of harmful bacteria such as E. Coli and Salmonella. However, supplemental aureomycin had non-selective effects on caecal microflora which inhibited all bacteria. Moreover, the combination of FOS and B. subtilis had much better improvement on caecal micro-ecosystem for broiler than they were used solely. Dietary addition of FOS or B. subtilis improved performance of broilers to the levels of those fed the diet with aureomycin and the combination of FOS and bacillus had better effects on reducing diarrhea rate and promoting growth than they were used solely.

Abstract Multi-color CCD photometric update of the bright high amplitude δ Scuti star ZZ Microscopium (ZZ Mic) is presented. We find that the B band has the highest amplitude at 0.47 mag while the V band amplitude is smaller at 0.38 mag. The revised pulsation period 0.06717850 day is similar to most recent previous estimates. We did not detect secondary mode pulsations. We find the temperature of the star varies by 720 K during pulsations and its radius changes by 0.1 R ☉. We estimate the mass of ZZ Mic as 1.93 M ☉ and surface gravity g as 4.19.

Abstract (sommario):

This study aimed to investigate the association between sleep behaviors and body composition, which was measured by bioelectrical impedance analysis (BIA) among Chinese adolescents. Overall, 444 students (65.3% females, 19.12 ± 1.177 years) completed questionnaires describing sleep characteristics. Sleep characteristics were derived from subjective means. Body composition was obtained from BIA by InBody 720 (Biospace Co. Ltd., Seoul, Republic of Korea). Regression models tested relationships between sleep and body composition after adjustment for covariates. Students with weekday nap duration (>30 min/d) exerted higher waist-height ratio (WHtR) (B = 0.013, FDR-corrected p = 0.080). Average sleep duration (≤7 h/d) was linked to more WHtR (B = 0.016, FDR-corrected p = 0.080). People with high social jetlag showed gained visceral fat area (B = 7.475), WHtR (B = 0.015), waist to hip ratio (B = 0.012), fat mass index (B = 0.663) and body fat percentage (B = 1.703) (all FDR-corrected p < 0.1). Individuals with screen time before sleep (>0.5 h) exhibited higher visceral fat area (B = 7.934, FDR-corrected p = 0.064), WHtR (B = 0.017, FDR-corrected p = 0.080), waist to hip ratio (B = 0.016, FDR-corrected p = 0.090), fat mass index (B = 0.902, FDR-corrected p = 0.069) and body fat percentage (B = 2.892, FDR-corrected p = 0.018). We found poor sleep characteristics were closely related to general and abdominal obesity.

Abstract A collaborative study was conducted to evaluate the performance of the VITEK® 2 Gram-Negative (GN) Identification card for use with the VITEK 2 automated microbial identification system. The GN test card is used in the identification of fermenting and nonfermenting Gram-negative bacilli, including the select agent organisms Brucella melitensis, Francisella tularensis, Burkholderia mallei, B. pseudomallei, and Yersinia pestis. The VITEK 2 GN card is based on 47 biochemical tests measuring carbon source utilization, inhibition and resistance, and enzymatic activities. A total of 20 laboratories representing government, industry, and private testing facilities throughout the United States participated. In this study, 720 Gram-negative inclusivity isolates were analyzed by the GN Identification method. Of the 720 well-characterized isolates, 707 were identified correctly, 0 were misidentified, 0 were unidentified, and 13 were not characterized as a Gram-negative organism. Additionally, 120 isolates exclusive of fermenting and nonfermenting Gram-negative bacilli were screened by Gram stain. A total of 117 isolates were correctly excluded. Three organisms were incorrectly characterized by Gram stain procedures, resulting in incorrect analysis and misidentification by VITEK 2 GN. The VITEK 2 GN identification method is an acceptable automated method for the rapid identification of Gram-negative bacteria.

Abstract (sommario):

Sub-lethal doses of herbicides can promote plant growth and have a positive effect on an organism this is called hormesis. The purpose of this study was to test the effects of sub-lethal doses of glyphosate on soybean (Glycine max (L.) Merr.) (1.8, 3.6, 7.2, 36, 180, and 720 g ha−1) and Amaranthus retroflexus L. (7.2, 36, 180, 720, 1440, and 2880 g ha−1). Different biological parameters, such as phytotoxicity, fresh weight, root length, content of photosynthetic pigments, and shikimate concentration, were measured. Glyphosate in doses of 1440 and 2880 g ha−1 destroyed A. retroflexus plants. A fresh weight of A. retroflexus at a dose of 36 g ha−1 was reduced by 76.31%, while for the soybean it was reduced by 19.26%. At the highest dose, the shikimate concentration was 145% in the soybean, while in A. retroflexus, the concentration increased by 58.80% compared to the control plants. All doses of glyphosate were statistically significantly different in terms of chlorophyll a content, while higher doses in A. retroflexus caused chlorophyll b to decrease. The change in the production of carotenoids was not statistically significant. The results showed that sub-lethal amounts of glyphosate did not lead to stimulation of measured parameters of soybean.

O experimento foi constituído da variedade de cafeeiro (Coffea arabica L.) Catuaí IAC 44 cultivada a 720 e 950 m de altitude, no município de Martins Soares-MG. O delineamento experimental foi inteiramente ao acaso, com três repetições, usando um esquema de parcela subdividida no tempo. O aumento da altitude influenciou o ciclo reprodutivo do cafeeiro, demandando maior tempo para formação dos frutos. O consumo de nutrientes pelos frutos, assim como o enchimento de grãos, foi mais crítico em condições de menor altitude, já que a planta necessitou completar esses processos em menor espaço de tempo. No estádio de expansão rápida, a percentagem de acúmulo de micronutrientes foi maior na altitude de 720 m, comparada à de 950 m. De modo geral, a altitude influenciou a variação das concentrações foliares de nutrientes, apesar de não se ter observado resposta-padrão da concentração foliar ao aumento da altitude. Conclui-se que a altitude teve influência na extensão do ciclo, bem como no acúmulo de micronutrientes em frutos e na variação, das concentrações foliares destes elementos em folhas de cafeeiro.

Abstract (sommario):

PURPOSE: Difficulty in cleaning resilient denture liners remains a material disadvantage. The purpose of the present study was to evaluate the effect of denture cleansers on hardness of resilient liner materials. MATERIALS AND METHODS: Three resilient liners, Luci Sof® (Dentsply), Molloplast-B® (Dentax), and Sofreliner® (Tokuyama), and two denture cleansers, Efferdent® (Warner-Lamber), and 0.5% alkaline hypochlorite preparation were used. Twenty specimens of each material were prepared, measuring 25X15X3mm. Two denture cleansing approaches were used: 1) alkaline hypochlorite, for 20 minutes; 2) alkaline peroxide, for 30 minutes. This procedure was repeated 8 times a day, during 90 days. The specimens were evaluated before and after 360 and 720 cycles, to simulate 1 and 2 years of clinical cleaning procedures, respectively. The Shore A hardness was evaluated in a durometer (Teclock GS-709A), with a penetrating load of 10N for 1 second. Any macroscopic changes, such as loss of color or alteration in surface texture were recorded by one observer. All numeric data were subject to ANOVA with repeated measures followed by Tukey's test (alpha= 0.05). RESULTS: All materials were significantly different, independently to time and treatment. Initially, Luci Sof® and Sofreliner® immersed in either hypochlorite or peroxide increased the hardness mean values significantly. These hardness mean values decreased significantly after 720 cycles. Molloplast-B® showed no significant difference after the treatments, in any time. CONCLUSIONS: Denture cleansers had no effect on hardness of the resilient denture liners evaluated after 2 years of in vivo simulated conditions of hygiene. Sofreliner® was the smoothest material before and after all treatments.

Abstract (sommario):

To improve the oxidation resistance of diamond, chromium boron carbide (Cr–B–C) coatings were synthesized through high temperature solid state synthesis and molten salt method on diamond particles in this paper. After holding the raw material at 900 °C for 2 h, the diamond surface was completely and uniformly covered by Cr–B–C coatings. Oxidation resistance of the diamond coated Cr–B–C was determined by the thermogravimetric analysis (TGA). The results revealed that the Cr–B–C coatings held the diamonds for 100%-mass in air atmosphere until 1151 °C, which was much better than the uncoated diamonds (720 °C) and the B4C-coated diamonds (1090 °C). When Cr–B–C-coated diamond was annealed in air, Cr2O3 and B2O3 were formed as oxygen barrier layer to protect diamond from oxidation. The formation of B2O3 with high temperature fluidity was conducive to avoiding Cr2O3 delamination due to volume expansion during oxidation in air. Furthermore, the presence of Cr2O3 provided lasting protection by reducing the evaporation of B2O3. The oxidation products (B2O3 and Cr2O3) prove a complementary functional protection on diamond particles from oxidation.

The binary system Al-Te contains the intermediate phases AlTe (m.p. 857 °C, syntectic). Al2Te3 (α-phase stable up to 720 °C; β-phase: m.p. 903 °C, congruent) and Al2Te5 (stable between 415 °C and 465 °C, incongruent). The crystal structure of α-Al2Te3 is monoclinic (super-structure; a = 41.565(8) Å, b = 7.189(1) Å, c = 25.477(7) Å, β = 90.21(2)°. Z = 48. Dx = 4.57g/cm3). Te positions of the sub-cell (monoclinic P21; a/3, b, c/6, β) were determined by direct methods; Te atoms are arranged in close-packed layers which are stacked along [100] with the sequence ABCBA. A metastable cubic phase of composition Al2Te3 (Zinc blende-type-structure; a = 5.949(1) Å; Al with random distribution) is obtained by thermal decomposition of ternary compounds AlTeX (X = Cl, Br, I)

Abstract (sommario):

Hepatitis B virus (HBV) infection is endemic in Nigeria and constitutes a public health menace. The prevalence of HBV infection in many professional groups has been described in Nigeria. However, literature on HBV infection among female sex workers (FSW) in Nigeria is scanty. FSW in Nigeria are not subjected to a preventive control of HBV infection. This study assesses the extent of spread of HBV among FSW in Nigeria. Seven hundred and twenty (n = 720) FSW (mean age = 26.7 years) were tested for hepatitis B surface antigen (HBsAg) by a double antibody sandwich ELISA method. The overall HBV prevalence among the FSW was 17.1%. FSWs between the ages of 31-35 year (20.5%) and those with 'age-at-first-sex' below 10 years of age (28%) were most affected. This high prevalence of a vaccine preventable disease is unacceptable, therefore, vaccination of this high risk HBV reservoir group should be considered worthwhile.

Abstract (sommario):

Entre as doenças invasivas causadas pelo Haemophilus influenzae tipo b (Hib), destacam-se, pela freqüência e gravidade, as pneumonias e as meningites. No período de 1993 a 1997, foram notificados, em Minas Gerais, 720 casos de meningites por Hib, sendo a causa mais freqüente de meningite bacteriana em menores de um ano e a segunda causa no total de meningites. Entretanto, estimou-se uma ocorrência total de 1.160 casos considerando as meningites bacterianas não especificadas. O total de casos estimados de doença invasiva por Hib parece justificar a recente inclusão da vacina no esquema básico de imunizações. O alto custo da vacina reforça a necessidade de melhorar a vigilância epidemiológica da meningite, que constitui uma das fragilidades das ações de controle desta doença.

Abstract (sommario):

Temporal and spatial variations in ozone levels and temporal changes in solar radiation greatly influence ultraviolet radiation incidence to crops throughout their growth, yet the interactive effects of CO2 and UV-B radiation on Basil production under sunlight environmental conditions has not been studied. Basil ‘Genovese’ plants grown under sunlit plant growth chambers were subjected to a combination of supplemental UV-B (0 and 10 kJ m−2d−1) and ambient (420 ppm) and elevated (720 ppm) CO2 treatments for 38 days after 14 days of germination. UV-B radiation treatments caused a decrease in basil stem branching, fresh mass, and stem dry mass under both CO2 treatments when harvested after 17 and 38 days of treatment. There was also an increase in basil leaf surface wax under UV-B (10 kJ m−2d−1) treatment compared to controls (0 kJ m−2d−1). Elevated CO2 treatments caused a decrease in morphological features, including specific leaf area and fresh mass. Interactive effects between UV-B and CO2 treatments existed for some morphological features, including plant height, root surface area, and average root diameter. Understanding the impacts that CO2 and UV-B radiation treatments have on basilcan improve existing varieties for increased tolerance while simultaneously improving yield, plant morphology, and physiology.

Jalakan Village in Pandak District, Kabupaten Bantul has the characteristics of limestone hills. The source of clean water of the residents contained levels of hardness of 391 mg/l CaCO3. The study was aimed to decrease the water hardness by implementing two types of filtration, by con-ducting a quasi experiment with pre-test post-test design. As the study object was local water company (PAM-Des) distribution in one of the consumer's house. The distribution water was fil-tered using Type A filter (5 cm activated carbon, 14,5 cm cation resin) and Type B (5 cm activa-ted carbon, 9,5 cm zeolite, 5 cm cation resin). The flow of water debit into the filter housing is 500 ml/minute, with 82,44 seconds contact time, and filtration capacity as much as 720 l/day. The Type A filter can reduce hardness level 72,93 %, higher than that of Type B which was 67,58 %. Data analysis with independent sample t-test obtained p-value of 0,013, which means that the different decrease is significant.

O estudo foi conduzido com o objetivo de avaliar a seletividade de alguns herbicidas inibidores de ALS e FS II aplicados em pós-emergência em plantas de Brachiaria brizantha cv. Marandu e Brachiaria decumbens cv. Basilisk em condições de campo e seu efeito na qualidade das sementes. Os herbicidas testados (em g/ha) foram: imazethapyr a 100; chlorimuronethyl a 15; nicosulfuron a 50; bentazon a 720; e atrazine a 3.000, além de uma testemunha, sem aplicação de herbicidas. Dois experimentos em campo foram instalados em delineamento em blocos casualizados com quatro repetições e os ensaios de laboratório em delineamento inteiramente casualizado, com 16 repetições. Todos os herbicidas testados tiveram algum efeito de fitointoxicação visual aos cultivares avaliados. O nicosulfuron foi o herbicida que visualmente proporcionou os níveis mais elevados de injúrias às plantas de B. decumbens e B. brizantha. A produção de MS de B. brizantha nos estádios iniciais de crescimento foi reduzida pelos herbicidas nicosulfuron e atrazine, enquanto, em B. decumbens, apenas o herbicida nicosulfuron ocasionou redução da produção de MS. A qualidade das sementes de ambos os cultivares foi afetada pelo nicosulfuron, que induziu a dormência em sementes de B. decumbens, reduziu a porcentagem de sementes normais e, assim como o atrazine, aumentou a porcentagem de sementes mortas.

Abstract (sommario):

We take the data of twin kilohertz quasi-periodic oscillations (kHz QPOs) in neutron stars (NSs) published before 2011 as the samples, which include 15 Atoll sources and 8 Z sources. Then we test the correlation between the twin peak kHz QPOs, and compare with the samples. We find the power law relation between the lower-frequency (ν1) and the upper-frequency (ν2) of kHz QPOs can fit the data much better than the other models. For the Atoll (Z) sources, the best fitting coefficient and index of power law are a = 687 (720) and b =1.50 (1.83) respectively. The Chi-square per degree of freedom (χ2/d.o.f.) are 1.93 and 1.49 respectively.

Abstract (sommario):

The effect of pre-weld heat treatment on the microstructure and low-temperature impact toughness of the coarse-grained heat-affected zone (CGHAZ) after simulated welding was systematically investigated through the utilization of scanning electron microscopy (SEM) and electron back-scattering diffraction (EBSD). The Charpy impact test validated the presence of an optimal pre-weld heat treatment condition, resulting in the highest impact toughness observed in the CGHAZ. Three temperatures for pre-weld heat treatment (690, 720 and 750 °C) were used to obtain three different matrices (Steel 1, Steel 2, Steel 3) for simulated welding. The optimal pre-weld heat treatment is 720 °C for 15 min followed by water quench. Microstructure characterization showed that there is an evident microstructure comprising bainite (B) in Steel 1 and Steel 2 after pre-weld heat treatment, while the addition of martensite (M) with the pre-weld heat treatment temperature exceeds Ac1 by almost 60 °C (Steel 3). These differences in microstructures obtained from pre-weld heat treatment influence the refinement of high-temperature austenite during subsequent simulated welding reheating processes, resulting in distinct microstructural characteristics in the CGHAZ. After the optimal pre-weld heat treatment, Steel 2 subjected to single-pass welding thermal simulation demonstrates a refined microstructure characterized by a high density of high-angle grain boundaries (HAGBs) within the CGHAZ, particularly evident in block boundaries. These boundaries effectively prevent the propagation of brittle cracks, thereby enhancing the impact toughness.
