A global transport packaging guideline for selected business areas

In this Master’s Thesis a global transport packaging guideline for selected business areas was compiled for the Fiskars the company, which provides branded consumer goods for home, garden and outdoor use. The business areas included were Home and Garden business areas. The aim of the guideline was to be a comprehensive guide for the suppliers, product development, operations and external vendors of the company. The guideline consists of written instructions, tables and illustrations that provide useful information for players working with transport packages from sourcing through to shipments. As the role of corporate responsibility and sustainability has grown, a part of responsible manufacturing strategy includes using materials that are re-usable, recyclable or recoverable as energy or through composting. Hence packaging waste management implementations of different regions were also inspected. The resulting guide covers a range of topics concerning packaging and its transport. The topics include legal requirements, restricted materials and substances, preferred materials, markings, labeling of boxes, logistics and distribution center requirements, physical testing and an inspection checklist.

Germinação de sementes aéreas e subterrâneas de Commelina benghalensis

O conhecimento dos mecanismos de reprodução de uma espécie de planta daninha, principalmente em relação à dormência e germinação de suas sementes, é de grande importância na determinação do método e da época ideal de seu controle. Com o objetivo de avaliar a germinação de sementes aéreas e subterrâneas de Commelina benghalensis, plantas desta espécie foram cultivadas em vasos, em casa de vegetação, nas condições de Viçosa, Estado de Minas Gerais, Brasil. Semente subterrânea grande (SSG) e semente aérea pequena (SAP) apresentaram o maior e o menor peso (8,81 e 1,90 mg/semente, respectivamente). Semente aérea grande (SAG) e semente subterrânea pequena (SSP) apresentaram pesos intermediários (3,65 e 3,51 mg/semente, respectivamente), porém semelhantes entre si. A data de coleta das sementes aéreas influenciou seu peso, observando-se, nas condições do experimento e no intervalo considerado (setembro a dezembro), maior peso de semente na primeira coleta (24/9/1999). A germinação das sementes aéreas não foi influenciada pelo tempo de armazenamento. Sementes aéreas pequenas germinaram melhor a 20-35 ºC, e as grandes, a 25 ºC. A germinação de sementes aéreas recém-colhidas variou de 7,50% em SAP a 21,67% em SAG/E (semente aérea grande com envoltório). O armazenamento por quatro meses aumentou a porcentagem de germinação de SAG e não alterou a de SAG/E e SAP. Sementes subterrâneas pequenas e grandes armazenadas por três meses apresentaram 32,5 e 92,5% de germinação, respectivamente. O aumento do tempo de armazenamento de três para seis meses diminuiu a porcentagem de germinação de SSG e SSP. O calor seco aumentou a porcentagem de germinação de SAG/E e SSP, não alterou a de SAG e SAP e diminuiu a de SSG. O grau de dormência diferiu muito entre os quatro tipos de sementes. A produção de sementes polimórficas com grandes diferenças no grau de dormência permite que C. benghalensis germine e se estabeleça nos mais diversificados ambientes e épocas do ano, o que dificulta o manejo desta espécie daninha.

Differentiation of Metabolically Distinct Areas within Head and Neck Region using Dynamic 18F-FDG Positron Emission Tomography Imaging

Positron Emission Tomography (PET) using ¹⁸F-FDG is playing a vital role in the diagnosis and treatment planning of cancer. However, the most widely used radiotracer, ¹⁸F-FDG, is not specific for tumours and can also accumulate in inflammatory lesions as well as normal physiologically active tissues making diagnosis and treatment planning complicated for the physicians. Malignant, inflammatory and normal tissues are known to have different pathways for glucose metabolism which could possibly be evident from different characteristics of the time activity curves from a dynamic PET acquisition protocol. Therefore, we aimed to develop new image analysis methods, for PET scans of the head and neck region, which could differentiate between inflammation, tumour and normal tissues using this functional information within these radiotracer uptake areas. We developed different dynamic features from the time activity curves of voxels in these areas and compared them with the widely used static parameter, SUV, using Gaussian Mixture Model algorithm as well as K-means algorithm in order to assess their effectiveness in discriminating metabolically different areas. Moreover, we also correlated dynamic features with other clinical metrics obtained independently of PET imaging. The results show that some of the developed features can prove to be useful in differentiating tumour tissues from inflammatory regions and some dynamic features also provide positive correlations with clinical metrics. If these proposed methods are further explored then they can prove to be useful in reducing false positive tumour detections and developing real world applications for tumour diagnosis and contouring.

Estádios de desenvolvimento e vias de contato e absorção dos herbicidas na inviabilização de tubérculos de Cyperus rotundus

Herbicidas que inviabilizam tubérculos de tiririca (Cyperus rotundus) quando absorvidos nas folhas ou na solução do solo, garantem melhor desempenho para a desinfestação gradativa da área. O objetivo do presente trabalho foi avaliar os estádios de crescimento mais adequados para a aplicação de herbicidas em pós-emergência, além da possibilidade de ação dos principais herbicidas na parte subterrânea da tiririca após aplicação localizada na parte aérea, no solo e sobre ambos os meios. Foram conduzidos dois experimentos em casa de vegetação do Departamento de Fitossanidade da Universidade Estadual Paulista, campus de Jaboticabal-SP. Os resultados do primeiro experimento mostraram que todos os herbicidas estudados (trifloxysulfuron-sodium + ametrine, halosulfuron, sulfentrazone e imazapic) proporcionaram reduções significativas no número de tubérculos viáveis, de forma coerente com suas características de atuação e pela via em que são recomendados. No segundo experimento, as maiores porcentagens de tubérculos afetados na seqüência das "cadeias", a partir das manifestações epígeas originais e derivadas, foram obtidas nas aplicações de trifloxysulfuron-sodium + ametrine nos estádios "jovem" e de pré-florescimento das plantas de tiririca, de halosulfuron no estádio "jovem" e de glyphosate no de pré-florescimento.

Germinação de sementes aéreas pequenas de trapoeraba (Commelina benghalensis)

O conhecimento científico sobre a biologia de plantas daninhas relacionado ao fluxo de emergência das plântulas, às causas de dormência das sementes e à profundidade máxima de emergência contribui significativamente para a utilização de estratégias racionais de manejo dessas plantas na agricultura. Assim, este trabalho foi desenvolvido com o objetivo de avaliar a germinação de sementes e a emergência da plântula de sementes aéreas pequenas de trapoeraba (Commelina benghalensis). Para isso, as sementes foram submetidas à superação de dormência em solução de ácido sulfúrico (por períodos de 1, 2, 3, 4 e 5 minutos), em diferentes condições de temperaturas (temperaturas médias de 16,1; 18,6; 20,6; 23,1; 25,0; 26,9; 29,2; 31,1; e 33,6 ºC), de luz (com e sem) e de profundidade de semeadura (0, 5, 10, 20, 40 e 80 mm). A temperatura ótima para germinação da trapoeraba foi de 25 ºC. Não houve efeito da luz na germinação das sementes. Não se observou interferência positiva na germinação por consequência do tratamento das sementes com ácido sulfúrico, em diferentes períodos de exposição, indicando que as sementes de trapoeraba não possuem impermeabilidade do tegumento à água. A emergência das plântulas de trapoeraba é influenciada negativamente e de forma linear pela profundidade de semeadura dos propágulos no substrato. Não houve emergência das plântulas quando as sementes foram depositadas a 80 mm de profundidade. O substrato areia favorece a emergência das plântulas.

Phytosociology in agricultural areas submitted to distinct wintercropping management

Studies related to weed dynamics are essential for agricultural sustainability in tropical soils, as their interference can cause significant yield losses, especially in crops with lower competitive ability. This study aimed to assess the composition of weed communities in the third cropping season in areas submitted to distinct wintercroppings for two consecutive years. Evaluations were made in terms of species composition, level of infestation, and severity of occurrence of each weed species in relation to the others within the same area. The wintercropping management systems were: (1) Brachiaria ruziziensis; (2) corn intercropped with B. ruziziensis; (3) corn and (4) cowpea. Plant communities under these wintercrop systems were evaluated in the third year in terms of relative frequency, relative dominance, relative abundance and importance index for each species. Areas were also compared in terms of species composition by the Sorensen's similarity coefficient. Two years of distinct wintercrop managements were not enough to cause a significant shift in terms of weed composition and severity in a given area. There is also evidence that some weed species are more favored by specific crops, although the causes of this selective behavior are not fully explored in this article. The presence of B. ruziziensis, either alone or intercropped with corn, resulted in lower similarity coefficients when compared to areas where this species was not present. It is suggested that several mechanisms briefly discussed may be involved in the impact of the presence of B. ruziziensis on the weed community.

Weeds occurrence in areas submitted to distinct winter crops

In the Western Region of Brazil, it is usual to have two agricultural harvests in the same cropping season. Usually the first crop is soybean, followed by corn. In areas where corn is not planted due to a delayed harvest of soybean, farmers generally do not use winter crops. For these areas, the planting of winter oilseed crops aiming at the production of bio-fuels is one of the best alternatives; in addition, this would help in reducing the occurrence of weed species at the following summer crop. This study aimed to assessing the weed community in distinct winter crops post soybean crop, in terms of species composition, level of infestation and severity of occurrence. The following treatments were evaluated: agriculture under a no-till system with winter fallow, winter oilseed crops (crambe, radish, rapeseed) with no-till agriculture in the summer, and agriculture under a conventional tillage system with winter fallow. Phytosociological evaluations of all treatments were carried out 75 DAE of the oilseed crops, and the diversity indexes of Margalef, Menhinick, Simpson, and Shannon-Weiner were determined. Areas were also grouped by cluster analysis based on UPGMA applied at Jaccard's similarity matrix. Among the treatments with winter coverage, radish was the most efficient crop in suppressing the occurrence of weed species. The area with conventional tillage agriculture and winter fallow allowed for a higher occurrence of troublesome weeds. On the other hand, the area under fallow showed the highest absolute level of infestation. Overall, oilseed crops in the winter contribute to lower levels of infestation by weed species in these areas.

Correlation of soil properties with weed ocurrence in sugarcane areas

Soil properties can influence weed community composition and weed density agricultural area. Knowing this relationship would allow to choose the best strategy for the control of such plants. This study aimed to investigate the correlation between weed density and chemical and physical attributes of soil in three areas (UCO, USC, and UPA) for commercial sugarcane cultivation in Campos dos Goytacazes, RJ. Grids of 40 m x 40 m were established in the areas, and soil samples were collected at the intersection points for physical and chemical analysis and evaluation of the soil seed bank (SSB), followed by a phyto-sociological survey of the weeds present. Samples were collected during two periods: February/March and June/July, 2010. SSB presented the greatest number of species per vegetation evaluated in the two sampling periods. Clay content had a positive effect leading to greater weed density in all areas (UCO, USC and UPA) in at least one of the densities (0-10 and 10-20 cm). On the other hand, sand content, when significant, presented a negative correlation with plant density in all the SSB areas analyzed. The pH negatively influenced the density of the species found through the phyto-sociological survey at USC and UPA. Cyperus rotundus, dominant in all areas, correlated positively with phosphorus, potassium, and clay content and negatively with pH and high sand content.

Dormancy studies on Euphorbia dracunculoides and Astragalus spp.: major weeds of arid areas

The aim of this study was to examine the dormancy behavior of Euphorbia dracunculoides and Astragalus spp., weeds of arid chickpea. The dormancy breaking treatments were: Gibberalic acid (GA3) and Thiourea each at 50, 100, 150, 200, 250, and 300 ppm and Potassium nitrate (KNO3) at 5,000, 10,000, 15,000, 20,000, 25,000, and 30,000 ppm (24 h soaking). Germination (G) percentage and germination energy (GE) of E. dracunculoides was maximum (89 and 22, respectively) at 250 ppm concentration of GA3 and 81.50 and 11.50 at 15000 ppm concentration of KNO3. Thiourea at 250 and 300 ppm resulted in maximum G percentage (51) and GE (25.50) of E. dracunculoides, whereas the G percentage and GE of Astragalus spp. were maximum (28 and 19, respectively) at the lowest concentration of GA3 (50 ppm). On the other hand, 5000 ppm and 150 ppm concentration of KNO3 and Thiourea showed maximum GE (19.5) and G percentage (28) of Astragalus spp., respectively. Overall, effective dormancy breaking chemical against E. dracunculoides was GA3 (250 ppm) while in Astragalus spp. none of chemicals showed very impressive results. These results showed that both weeds' seeds have dormancy in their habit. Hot water treatment and the above mentioned chemicals (best concentrations) when used with 4, 8, and 12 hours soaking showed ineffective results.

DETECTION OF GLYPHOSATE-RESISTANT PALMER AMARANTH (Amaranthus palmeri) IN AGRICULTURAL AREAS OF MATO GROSSO, BRAZIL

ABSTRACT The recent introduction of Palmer amaranth (Amaranthus palmeri) in Brazilian agricultural areas may promote several changes on weed management, especially in no-till systems and in glyphosate-resistant crops, since glyphosate-resistant biotypes of A. palmerihave been frequently selected in other countries. Therefore, this research was developed in order to evaluate the glyphosate susceptibility of a Palmer amaranth biotype recently identified in the State of Mato Grosso, Brazil. For this purpose, glyphosate susceptibility of three Amaranthusbiotypes was compared: A.hybridus var. patulus, collected in the State of Rio Grande do Sul - Brazil; A.hybridus var. patulus, collected in the State of São Paulo - Brazil; and A.palmeri, collected in the State of Mato Grosso - Brazil. Dose-response curves were generated for all biotypes, considering eight rates of glyphosate and six replicates. All the experiments were repeated twice. Both A.hybridus biotypes were satisfactorily controlled by glyphosate, demanding rates equal to or lower than 541.15 g a.e. ha-1 for 80% control (LD80). The A.palmeri biotype was not controlled by glyphosate in any of the assessments and required rates greater than 4,500 g a.e. ha-1 to reach LD80, which are economically and environmentally unacceptable. Comparison of the Brazilian A.palmeri biotype to the A. hybridus biotypes, as well as, to the results available in scientific international literature, led to the conclusion that the Brazilian Palmer amaranth biotype is resistant to glyphosate.
