Increasing irrigation levels from 37% to 84% of Class "A" Pan evaporation produced a linear increase in cane yield from 65 to 146 tonslha. The response with burnt cane was greater due to more severe moisture stress, and there was also an increase in cane yield between 84% and 100% Pan which was absent in trashed cane. Maximum sucrose content, as well as brix, purity and recoverable sugar % cane...
NĚMEC P. 2015. Comparison of modern forest inventory method with the common method for management of tropical rainforest in the Peruvian Amazon. Electronic devices consisting of field computer, laser rangefinder, electronic compass and global positioning system unit were used for data collection in the tropical rainforest of the Peruvian Amazon with the objective of comparing forest inventory m...
This paper report experiences from the processing and mosaicking of 518 TanDEM-X image pairs covering the entirety of Sweden, with two single map products of above-ground biomass (AGB) and forest stem volume (VOL), both with 10 m resolution. The main objective was to explore the possibilities and overcome the challenges related to forest mapping extending a large number of adjacent satellite sc...
We explore the biophysical potential and economic attractiveness of black spruce (Picea mariana) regeneration in eastern Canada under the high greenhouse gas emission scenario (RCP 8.5) of the Intergovernmental Panel on Climate Change (IPCC). The study integrates net primary productivity and net ecosystem productivity estimates from three major global climate models (GCMs), growth and yield equ...
In this study, the potential of using very high resolution Pléiades imagery to estimate a number of common forest attributes for 10-m plots in boreal forest was examined, when a high-resolution terrain model was available. The explanatory variables were derived from three processing alternatives. Height metrics were extracted from image matching of the images acquired from different incidence a...
Türkiye'nin yüzölçümü yaklaşık 78.5 milyon ha, nüfusu 84 ve yıllık nüfus artış hızı 2020 itibari ile %1.09 olmuştur. Türkiye, hidrolojik özelliklerine uygun 25 havzaya bölünmüştür. Havzalarda ortalama akış 186 milyar m3 ’tür. Fırat-Dicle Nehri Havzası %28.4’lük su potansiyeline sahip olup, potansiyeli bakımından en büyük havzasıdır. toplam kullanılabilir potansiyelinin, 98 m3’ü yüzey suyu 14 ’ü...
یکی از مهمترین بیوسرامیک های مورد استفاده در پزشکی که تحقیقات زیادی را به خود اختصاص داده است هیدروکسی آپاتیت (ha) می باشد. هیدروکسی آپاتیت به دلیل نزدیک بودن ترکیب شیمیایی به بخش معدنی استخوان و در نتیجه زیست سازگاری عالی برای سال های زیادی به عنوان ماده کلینیکی و جایگزین استخوان مورد استفاده قرار گرفته است. مشکل اصلی هیدروکسی آپاتیت خالص مقاومت مکانیکی ضعیف آن است. در این کار پژوهشی با توجه...
Kabupaten Kupang merupakan salah satu kabupaten di Provinsi Nusa Tenggara Timur yang tergolong iklim tropis kering. Oleh karena itu, pemerintah pusat melalui BWS NT II membangun beberapa daerah irigasi satunya adalah Daerah Irigasi Air Sagu dengan luas sebesar 163 Ha sebagai alternatif untuk mengoptimalkan ketersediaan air terbatas. Penelitian ini bertujuan mengetahui besar debit andalan Metode...
The most important pollutants that cause water pollution are nitrogen and phosphorus from agricultural runoff called Non-Point Source Pollution (NPS). To solve this problem, management practices known as BMPs or Best Management Practices are applied. One of the common methods for Non-Point Source Pollution prediction is modeling. By modeling, efficiency of many practices can be tested before ap...
Nitrogen removal performance and the ammonia-oxidising bacterial (AOB) community were assessed in the batch loaded 1.3 ha saturated surface vertical flow wetland at CSBP Ltd, a fertiliser and chemical manufacturer located in Kwinana, Western Australia. From September 2008 to October 2009 water quality was monitored and sediment samples collected for bacterial analyses. During the period of stud...
