Break-up characteristics of Chena River Basin
No full textThe author has identified the following significant results. Results from snowmelt model were obtained showing the decreasing changes in snow depth for four elevational ranges in the Chena River Basin. This model is based on the energy balance of the snowpack and the results are shown on attached figures. Also, the measured hydrographs for two stations on the Chena River are shown. The next phase of the study will be to analyze the model using both ERTS-1 imagery and measured field values
Socioeconomic Sustainability of Chena Cultivation in the Forested Land of Hambantota District, Sri Lanka
No full textChena cultivation is one of the major agriculture systems and extensively practiced in rural areas of low country dry zone as their main livelihood. Generally, a slash-and-burn method is used to clear the land in the forested area where the land is prepared before the North-East monsoon starts. Short-duration, comparatively drought resistant crops such as grains, legumes, oil crops, and vegetables are commonly grown in Chena. However, scientific studies on Chena cultivation to assess socioeconomic status were limited in Sri Lanka. Therefore, this study attempted to assess the socioeconomic status of Chena farmers in the close proximity of forest lands in Southern part of Sri Lanka. Chena cultivation areas at Tissamaharama (8 Grama Niladhari divisions namely Gotabhayapura, Yodakandiya, Rathnelumwalayaya, Uddakandara, Viharamahadevipura, Ranakeliya, Wijayapura and Joolpallama) and Lunugamwehera (7 Grama Niladhari divisions namely Udamaththala, Padawgama, Pahalamaththala, Rabukwewa, new town-Lunugamwehera, new town-Weerawila and Keerthipura) Divisional Secretariats in Hambantota district was studied. 40 Chena farmers were purposively selected for the study. Primary data were collected from the farmers by using pre-tested structured questionnaire, personal interviews and field observations. Descriptive statistics and correlation tests were employed to analyse the data. Results revealed that farmers practiced four types of Chena such as Navadali Hena (clearing an untouched forest area), Ath Danduwa Hena (regrowth and cut), Mukulan Hena (consists of medium- sized trees) and Hen Kanaththa (land exist for survival). 98% of farmers are fully involved in chena cultivation in the study area. 32.5%, 22.5%, 20%, 12.5%, and 7.5% of farmers had 11-20, 21-30, 0-10, 31-40, and 41-50 years of experience, respectively in Chena cultivation. The result also revealed that 80% of the farmers were not a member of farmer`s societies and other organizations. A small number of farmers had received some relief from government such as fertilizer, agricultural extension services, 50% of subsidy seed, and 50% of subsidy loan. Chena farmers earned more than Rs.500,000.00 whereas the average income was Rs. 802,392.16 per annum. Further, 63% of the cost was contributed by labour followed next to land preparation (16%) and agrochemical (13%). Sweet melon, green gram, long beans, and tomato were recorded as major cultivated crops. Further, Chena areas were highly problematic by wildlife and cattle damage (87.5%), marketing issues (67.5%), legal (37.5%), drought (30%), and pest and diseases (27.5%). However, around 74% of respondents were willing to continue the Chena cultivation, because they have no other alternative livelihoods in this area. On the other hand, the majority (54%) were neutral or dissatisfied about their situation because they did not have land ownership. Introducing a registration procedure for land ownership, constructing the electrical fence to avoid wildlife damage, establishing a wildlife management unit to protect the wildlife habitat, and planning a proper irrigation method to secure the water supply throughout the year were the major suggestions to improve farming at a sustainable level of production and consumption.

SEED BANK DYNAMICS OF KEKILLA FERN LANDS AND ABANDONED CHENA UNDER PARTIAL SHADE AND FULL SUN CONDITIONS
No full textSeed bank dynamics can be considered an important component of the regeneration ofindividual plant populations and communities. Soil seed bank dynamics in Kekillafernlands and abandoned chena need to be studied as possible sources of regeneration forforest restoration of degraded lands.This study was done to understand regeneration dynamics of soil seed banks with referenceto two light regimes in Kekil1a fernlands and abandoned chena in the periphery ofSinharaja World Heritage Site.Sinharaja World Heritage Site is one of the least disturbed and biologically unique lowlandrain forests now remaining in Sri Lanka. Today some areas of the periphery of Sinharajaare covered with secondary scrub and Kekilla (Dicranopteris linearis) fernlands. Threesites of Kekilla fernlands and three sites of abandoned chena were selected for the study.Four soil samples were purposively collected from four different locations in each site.These four samples were pooled and mixed in a polythene bag. Eight trays were preparedusing one mixture of soil from one site. Four trays from each site were placed underpartial shade (750J.! mol m-2 S-1 ) and others were placed under full sunlight (2000J.! mol m-2S-I). Seeds inside the soils were allowed to germinate. Newly germinated seeds wererecorded every fifth day. All germinated seeds that were able to be identified wereremoved and counted once a month.Seedlings of 45 taxa were identified during the period of study. Among the countedseedlings a larger proportion was recruited under the partial shade treatment than full suntreatment. Results indicate that the number of species germinated from abandoned chenawas greater than that of Kekilla femlands. Finding suggest that in all treatments onlypioneer species germinated. Climax species were not represented in any of the sites orlight treatments
A study of the break-up characteristics of Chena River Basin using ERTS imagery
No full textThe author has identified the following significant results. The Chena River Basin was selected because of the availability of ground truth data for comparison. Very good agreement for snow distribution and rates of ablation was found between the ERTS-1 imagery, the snowmelt model, and field measurements. Monitoring snowmelt rates for relatively small basins appears to be practical. The main limitation of the ERTS-1 imagery is the interval of coverage. More frequent overflights providing coverage are needed for the study of transient hydrologic events. ERTS-1 data is most useful when used in conjunction with snowmelt prediction models and existing snow course data. These results should prove very useful in preliminary assessment of hydrologic conditions in ungaged watersheds and will provide a tool for month-to-month volume forecasting
"Americký způsob je odporné monstrum:" Vykreslení Americké společnosti v poezii Allena Ginsberga, Gregoryho Corsa, Amiriho Baraka a Chena Chena
No full textThis bachelor thesis deals with the portrayal and criticism of American society in the poetic works of twentieth and twenty-first century poets, namely Allen Ginsberg, Gregory Corso, Amiri Baraka and Chen Chen, focusing predominantly on the style of the depiction and issues addressed in the selected poems. The objective of this thesis is to determine some of the principal topics of their social critique and show the impact the historical context had in the composition of their poems and on the commentary contained therein. Selected poems of each author are analyzed separately to point out the notions that are unique to their portrayal and to show that despite differences in personalities and historical periods, certain issues of the United States are discussed and continue to be discussed by poets from both the twentieth and twenty-first centuries. The thesis demonstrates, however, that specific social and racial circumstances, together with historical context, inform each poet's writing, showing that the poets of the twentieth century pose different questions from the poets of the twenty-first century even as their opinion of American society as a whole remains critical.Tato bakalářská práce se zabývá zobrazením a kritikou americké společnosti v básnických dílech básníků dvacátého a jednadvacátého století, jmenovitě Allena Ginsberga, Gregoryho Corsa, Amiriho Baraky a Chena Chena, přičemž se zaměřuje především na styl zobrazení a problematiku řešenou ve vybraných básních. Záměrem této práce je určit některá ze zásadních témat jejich kritiky společnosti a ukázat, jaký vliv měl historický kontext na kompozici jejich básní a na kritiku v nich obsaženou. Vybrané básně každého autora jsou analyzovány zvlášť, aby bylo poukázáno na pojmy, které jsou pro jejich zobrazení jedinečné, a také aby bylo ukázáno, že navzdory rozdílům v jejich osobnostech a historických obdobích se určitými otázkami Spojených států zabývali a nadále zabývají básníci dvacátého i jednadvacátého století. Práce však ukazuje, že jejich specifická společenská třída a rasa spolu s historickým kontextem ovlivňují uměleckou tvorbu jednotlivých básníků, a ukazuje, že básníci dvacátého století kladou jiné otázky než básníci jednadvacátého, i když jejich názor na americkou společnost jako celek zůstává kritický.Ústav anglofonních literatur a kulturDepartment of Anglophone Literatures and CulturesFaculty of ArtsFilozofická fakult
Culture and characterization of human hepatocytes isolated from hepatitis C virus infected liver: Effect of collagen-coated surface and FBS-supplemented medium
No full textThe aim of this study is to maintain and prolong the viability and metabolic functions of hepatocytes isolated from hepatitis C virus (HCV)-
infected human livers. Collagen-coated surface and 10% fetal bovine serum (FBS) supplemented culture media were studied. Metabolic
functions and attachment ability of human hepatocytes in these conditions were compared with normalized conditions (Petri dish, medium
without FBS). Our results showed that collagen-coated dishes with 10% FBS-supplemented culture medium increased urea production and
albumin synthesis. Urea concentration remained stable (30 pg/cell/h) during the first 3-days when human hepatocytes were cultured in collagencoated
dishes. These hepatocytes showed higher urea production when compared with hepatocytes cultured in normal Petri dishes producing
36.4 and 31.7 pg/cell/h concentrations of urea, respectively. Albumin secretion rate was maximal on day 3 after plating (0.86 pg/cell/h). When
using culture medium supplemented with 10% FBS, the metabolic functions of hepatocytes were higher compared to when using normal
culture medium. This study demonstrates that human hepatocytes can be isolated from HCV-infected livers via surgical biopsies with high
cell yield rate, and their metabolic functions remain stable when cultured in collagen-coated dishes with FBS-rich medium for several days.
Base on these results, HCV-infected human hepatocytes can be used in the study of clinical diseases and in the performance of physiological
and pharmacological liver experiments in vitro
