Explaining First-Year Seedling Survival from Quality Distributions of Bare-Root Seedlings and Microsites in Industrial Plantations  [PDF]
Puskar N. Khanal, Thomas J. Dean, Scott D. Roberts, Donald L. Grebner, Thomas J. Straka
Open Journal of Forestry (OJF) , 2018, DOI: 10.4236/ojf.2018.83023
Abstract: First-year seedling survival impacts all subsequent management planning in plantation forestry. Descriptive statistics of first-year seedling survival data from the Louisiana Department of Agriculture and Forestry (LDAF) indicated that survival success reaches a plateau at between 79% - 85% under normal weather conditions. We provide an explanation for this plateau based on an analysis of seedling and microsite qualities involved in operational pine plantations by: 1) using a conceptual model demonstrating how variation in seedling quality and microsite quality interact to determine plantation survival, 2) presenting an example to characterize quality distributions of seedling and microsite qualities, and 3) comparing model outcomes based on measured distributions to realistic values of first-year survival. Simulation results indicated that consistent survival could result from random pairings of initial seedling and site quality distributions. LDAF data analysis indicated that 72% of seedlings were associated with the most frequent quality class that comprised seedlings with stem caliper between 3.2 to 4.7 mm and average stem height and volume of 25.75 cm and 3.43 cm3, respectively. Similarly, assessment of microsites at planting sites in Southeast Louisiana indicated that 48% of planted seedlings were associated with the most frequent microsite quality class which supported first-year height increment between 9 to 29 cm. Modelling of current operational practice indicated that using seedlings with larger caliper size would increase first year survival, but would result in higher establishment costs. The conceptual model could be modified to for use in other regions regardless of species types involved.

Abstract: INTRODUCTION: Urinary tract infection (UTI) is one of the major complications of immobility or bedridden condition. Between 46-59% of spinal cord injury patients develop urinary tract infection during the first year of trauma. UTI is a second most common type of infection, accounting for nearly 25% of all infections and a serious health problem affecting millions of people each year. The findings of the study might be helpful to the long term care health institution for the development the strategies to involve the caretakers to prevent urinary tract infection in bedridden patients. OBJECTIVE: The purpose of the study was to find out the level of knowledge and current practice of caretakers of bedridden patients on prevention of urinary tract infection. METHODS: The descriptive and cross-sectional study design was adopted in this study. A self-prepared structured interview questionnaire and observation checklist was used to collect data from 30 caretakers of hospitalized bedridden patients of Nepal Orthopedic Hospital and Spinal Injury Rehabilitation Center Jorpati implying purposive & convenient sampling technique. RESULTS: Out of30 caretakers, no one had adequate (>80%) knowledge and 46.6% had moderate (50-80%) knowledge and 53.3% had low (<50%) knowledge on meaning, high risk group, contributing factors, signs & symptoms, consequences and preventive measures of UTI as a whole. Caretaker's preventive practices of UTI for their bedridden patients were not satisfactory except encourage the patient for drinking 2-3 liters water per day. CONCLUSION: Majorities (53.3%) of the caretakers of bedridden patients had low level knowledge on preventive measures of UTI. Similarly UTI preventive practices of caretakers were also not satisfactory. Therefore, awareness raising programme on preventive measures of UTI need to be organized specially for caretakers.

Abstract: Engineering is one of the major fields of applied science without which no country can move forward in the present global context. The teaching/learning of engineering in Nepal is not possible without English at present. The present paper attempts to highlight the relevance of English language for teaching/learning engineering in Nepal, It also attempts to indicate the relevance of the language for engineers to work in their respective fields. The focus of the paper is to suggest planners and teachers to select the need-based English, for the specific engineering purposes in the present world of specialization. Key words: Applied Science; Teaching learning of engineering DOI: http://dx.doi.org/10.3126/jie.v8i1-2.5127 Journal of the Institute of Engineering Vol. 8, No. 1&2, 2010/2011 Page: 311-314 Uploaded Date : 20 July, 2011
Effects of Growing Conditions of Marigold in Ilam District, Nepal  [PDF]
Bikash Khanal
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.522354

Different growing conditions with temperature and sunlight variation could vary in flower growth and quality of marigold. Plant growth and flowering characteristics are compared in three different conditions viz. plastic house, shade house and open field. Three varieties of marigold viz. Marvel Yellow, Marvel Orange and Marvel Garland with similar cultural practices were grown and observed. Each variety with 6 replications was grown in three different growing conditions. Plant height, leaves formation, length of leaves, number of days to flower, number of flowers per plant and post harvest analysis were recorded. Plant growth characteristics followed by flowering behavior were found significantly better in plants grown under plastic house. During post harvest experiment Marvel Garland variety grown under plastic house with wet post harvest treatment was found significantly better compared to other conditions.

High Spatial Resolution Infrared Micro-Spectroscopy Reveals the Mechanism of Leaf Lignin Decomposition by Aquatic Fungi

Abstract: Organic carbon is a critical component of aquatic systems, providing energy storage and transfer between organisms. Fungi are a major decomposer group in the aquatic carbon cycle, and are one of few groups thought to be capable of breaking down woody (lignified) tissue. In this work we have used high spatial resolution (synchrotron light source) infrared micro-spectroscopy to study the interaction between aquatic fungi and lignified leaf vein material (xylem) from River Redgum trees (E. camaldulensis) endemic to the lowland rivers of South-Eastern Australia. The work provides spatially explicit evidence that fungal colonisation of leaf litter involves the oxidative breakdown of lignin immediately adjacent to the fungal tissue and depletion of the lignin-bound cellulose. Cellulose depletion occurs over relatively short length scales (5–15 μm) and highlights the likely importance of mechanical breakdown in accessing the carbohydrate content of this resource. Low bioavailability compounds (oxidized lignin and polyphenols of plant origin) remain in colonised leaves, even after fungal activity diminishes, and suggests a possible pathway for the sequestration of carbon in wetlands. The work shows that fungi likely have a critical role in the partitioning of lignified material into a biodegradable fraction that can re-enter the aquatic carbon cycle, and a recalcitrant fraction that enters long-term storage in sediments or contribute to the formation of dissolved organic carbon in the water column.

Abstract: Compound Poisson risk model has been simulated. It has started with exponential claim sizes. The simulations have checked for infinite ruin probabilities. An appropriate time window has been chosen to estimate and compare ruin probabilities. The infinite ruin probabilities of two-compound Poisson risk process have estimated and compared them with standard theoretical results.
On the water hazards in the trans-boundary Kosi River basin
N. Sh. Chen,G. Sh. Hu,W. Deng,N. Khanal
Natural Hazards and Earth System Sciences (NHESS) & Discussions (NHESSD) , 2013, DOI: 10.5194/nhess-13-795-2013
Abstract: The Kosi River is an important tributary of the Ganges River, which passes through China, Nepal and India. With a basin area of 71 500 km2, the Kosi River has the largest elevation drop in the world (from 8848 m of Mt Everest to 60 m of the Ganges Plain) and covers a broad spectrum of climate, soil, vegetation and socioeconomic zones. The basin suffers from multiple water related hazards including glacial lake outburst, debris flow, landslides, flooding, drought, soil erosion and sedimentation. This paper describes the characteristics of water hazards in the basin, based on the literature review and site investigation covering hydrology, meteorology, geology, geomorphology and socio-economics. Glacial lake outbursts are a huge threat to the local population in the region and they usually further trigger landslides and debris flows. Floods are usually a result of interaction between man-made hydraulic structures and the natural environment. Debris flows are widespread and occur in clusters. Droughts tend to last over long periods and affect vast areas. Rapid population increase, the decline of ecosystems and climate change could further exacerbate various hazards in the region. The paper has proposed a set of mitigating strategies and measures. It is an arduous challenge to implement them in practice. More investigations are needed to fill in the knowledge gaps.

Physics , 2013,
Abstract: An expression for rotational velocity of a test particle around the central mass in the invariant plane is derived. For this, a line element of Schwarzschild de-Sitter space-time is used to study the effect of cosmological constant ($\Lambda$) on the motion of both massive and massless particles. Using rotation curve data of 15 nearby spiral and barred spiral galaxies, we estimated the mass and $\Lambda$ of the galaxy. The mass of the galaxies are found to lie in the range 0.13-7.60 $\times$ 10$^{40}$ kg. The cosmological constant ($\Lambda$) is found to be negative ($-$0.03 to $-$0.10 $\times$ 10$^{-40}$ km$^{-2}$), suggesting the importance of anti-de Sitter space in the local bubble. Possible explanation of the results will be discussed.
