Four-year Growth Results from 16 Year Old Intensively Managed Low Density Loblolly Pine Plantations

In 1994 eighty four permanent research plots were established in two twelve year-old loblolly pine (Pinus taeda) plantations in East Texas. Plots differed in relation to: soil-site type, density of trees per acre, fertilization treatments, and competing vegetation control. Three levels of thinning treatments reduced the basal areas to 36,60, and 84 square feet of basal area (approximately 100,200, and 300 stems, respectively) per acre. All residual trees were pruned to a height of 25 feet. Plots were re-measured in 1995, 1996, and 1998. Significant differences in diameter and height growth rates were detected in 1996 and 1998. Average diameter growth rates from 1995 to 1998 ranged from 0.64 to 0.31 inches per year depending on density class and treatment type

Financial Analysis of Pruning Combined with Low Density Management of Southern Yellow Pine in East Texas: An Assessment

Time study was conducted on pruning of research plots in a IZyear-old loblolly pine (Pinus taeda) plantation thinned to 58 square feet basal area (190 trees) per acre. Pruning times with labor and equipment costs were used to determine per acre and per tree pruning costs. Pruning costs were used to find values necessary to break-even on a pruning investment. Soil expectation value (SEV) calculations were used to compare profitability of management utilizing heavy thinning with pruning to traditional management regimes. Calculations were performed using a current hourly wage of $8.00, stumpage price of$400.00, per thousand board feet (MBF) and real interest rates of 0.13,2.78,7.00, and 10.00 percent. Per acre combined labor and equipment cost was $116.07. Cost per tree to prune to a height of 25 feet was$0.61. Break-even values were found to range from $118.82 to$645.34 per acre depending on interest rate. Profit increase by utilizing low density management combined with pruning was found to range from $491.43 to$88,093.04 per acre over traditional management for a perpetual series of full rotations

Initial Investigation of Height-Diameter Relationships of Dominant Trees in the mixed Hardwood Bottomland Forests of East Texas

Three to five dominant trees from each of 445 ten-factor variable radius inventory points were utilized to evaluate the height- diameter relationships of 13 species or genera found on bottomland hardwood sites throughout east Texas. Regression analysis was performed using the linear model such that height = (30 + (31 x (d.b.h.). The species were placed into six groups: (1) pines (Pinus taeda and P. enchinata) ; (2) water oak/willow oak/white oak/swamp chestnut oak (Quercus nigra)/(Q. phe//os)/(Q. alba)/(Q. michauxi1) ; (3) blackgum/laurel oak/overcup oak (Nyssa sylvatica)/(Q. laurifolia)/(Q. lyrata); (4) ash/maple (Fraxinus spp.)/(Acerspp.); (5) hickories (Carya spp.), and (6) elms (Ulmus spp.), or were analyzed as individual species: (7) cherrybark oak (Q. pagoda) and (8) sweetgum (Liquidambar styraciflua) based on similar intercepts and slopes of the regression lines. The coefficients of the model were estimated and residual analysis conducted for each species group

Characterizing Fusiform Rust Incidence and Distribution in East Texas

Three measurement cycles were completed on an extensive network of loblolly( Pinus taeda L.) pine and slash (Pinus elliottii Engelm.) pine plots in industrial plantations throughout East Texas in 1984, 1987, and 1990.Because the incidence of fusiform rust caused by Cronartium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme had been recorded at each measurement, it is possible to characterize the temporal and geographic distribution of fusiform rust among these industrial pine plantations in East Texas. Average rust incidence for each species by two year age classes is presented. For loblolly pine, there is no apparent change in overall average incidence between 1987 and 1990, whereas for slash pine, there is an apparent overall average decline of about 7-8 percentage points. For some slash pine age classes, the incidence decline is 20-30 percentage points. Loblolly and slash pine rust incidence maps depict the geographic distribution of rust infection by plantation age groups in East Texas. South. J. Appl. For. 18(1):29-3

Stand Structure and Species Composition in Bottomland Hardwood Forests of East Texas

Bottomland hardwood forests, growing on the flood plains of rivers and streams, comprise about 14 percent (1.6 million acres) of the total commercial forest land in East Texas. These stands represent high values for a variety of forest uses such as timber production and wildlife habitat. However, information on these forests is not as complete as that of the southern U.S. For this study, data from 445 ten-factor variable radius inventory points were used to characterize stand structure, species composition and the general condition of bottomland hardwood forest throughout East Texas. The importance of this information and its impact on management practices is discussed

Sociodemographic factors and patient perceptions are associated with attitudes to kidney transplantation among haemodialysis patients

Background. Treatment decisions made by patients with chronic kidney disease are crucial in the renal transplantation process. These decisions are influenced, amongst other factors, by attitudes towards different treatment options, which are modulated by knowledge and perceptions about the disease and its treatment and many other subjective factors. Here we study the attitude of dialysis patients to renal transplantation and the association of sociodemographic characteristics, patient perceptions and experiences with this attitude. Methods. In a cross-sectional study, all patients from eight dialysis units in Budapest, Hungary, who were on haemodialysis for at least 3 months were approached to complete a self-administered questionnaire. Data collected from 459 patients younger than 70 years were analysed in this manuscript. Results. Mean age of the study population was 53 +/- 12 years, 54% were male and the prevalence of diabetes was 22%. Patients with positive attitude to renal transplantation were younger (51 +/- 11 versus 58 +/- 11 years), better educated, more likely to be employed (11% versus 4%) and had prior transplantation (15% versus 7%)(P < 0.05 for all). In a multivariate model, negative patient perceptions about transplantation, negative expectations about health outcomes after transplantation and the presence of fears about the transplant surgery were associated, in addition to incre- asing age, with unwillingness to consider transplantation. Conclusions. Negative attitudes to renal transplantation are associated with potentially modifiable factors. Based on this we suggest that it would be necessary to develop standardized, comprehensible patient information systems and personalized decision support to facilitate modality selection and to enable patients to make fully informed treatment decisions

Long-term results after liver transplantation for primary hepatic epithelioid hemangioendothelioma

Background: Hepatic epithelioid hemangioendothelioma (PHEHE) is a multifocal, low-grade malignant neoplasia characterized by its epithelial-like appearance and vascular endothelial histogenesis. The outcome of 16 patients treated with orthotopic liver transplantation (OLT) is the subject of this report. Methods: A retrospective study of 16 patients with HEHE (7 men, 9 women) with ages ranging from 24 to 58 years (mean 37 ± 10.6 years). Follow-up intervals ranged from 1 to 15 years (median of 4.5 years). Results: Actual patient survival at 1, 3, and 5 years was 100, 87.5, and 71.3%, respectively. Disease-free survival at 1, 3, and 5 years was 81.3, 68.8, and 60.2%, respectively. The 90-day operative mortality was 0. Involvement of the hilar lymph nodes or vascular invasion did not affect survival. The 5-year survival of HEHE compares favorably with that of hepatocellular carcinoma at the same stage (stage 4A): 71.3 versus 9.8% (p=0.001) Conclusions: The long-term survival obtained in this series justifies OLT for these tumors even in the presence of limited extrahepatic disease. © 1995 The Society of Surgical Oncology, Inc
