Soil loss and erosivity index of Padang Besar soil series (Petroferric Tropudult) I: Possible application of Cate-Nelson methods, Anderson-Nelson method and simplified ANOVM for the determination of critical value

Knowledge of the critical value for soil erosion data is useful in terms of soil conservation and management. An experiment was carried out in Universiti Pertanian Malaysia on Padang Besar soil series (Petroferric tropudult). The bare plot soil loss and rainfall characteristics were determined after every storm for a year. Soil loss and erosivity index (K.E. > 10) were fitted with different models. Various approaches were then adapted to study their suitability in obtaining critical values for soil erosion data. In this paper, an example showing the application of techniques and their principles is given. Results indicate that all the four procedures provide similar critical values despite their different principles. It is further showns that new Gate-Nelson technique and simplified ANOVM (Q' = 0.001) result in higher R 2 (0.84**) than the best quadratic model (R 2 = 0.54**). However, due to the principle of obtaining critical values for soil erosion data, it may suffice to use simplified ANOVM (ex = 0.001)

Abnormal activity detection in surveillance video scenes

Automated detection of abnormal activity assumes a significant task in surveillance applications. This paper presents an intelligent framework video surveillance to detect abnormal human activity in an academic environment that takes into account the security and emergency aspects by focusing on three abnormal activities (falling, boxing and waving). This framework designed to consist of the two essential processes: the first one is a tracking system that can follow targets with identify sets of features to understand human activity and measure descriptive information of each target. The second one is a decision system that can realize if the activity of the target track is "normal" or "abnormal” then energizing alarm when recognized abnormal activities

Dry matter and nutrient partitioning of kenaf (Hibiscus cannabinus L.) varieties grown on sandy bris soil

Dry matter and nutrient partitioning of different kenaf varieties grown on sandy Beach Ridges Interspersed with Swales (BRIS) soils were investigated. The experiment was conducted under a shade house condition. Five kenaf varieties, V36, G4, KK60, HC2 and HC95 were grown in pots, replicated four times in a randomized complete block design. Plants were partitioned into roots, stems, and leaves and the dry weights were recorded at harvesting time. The dry matter accumulation differed significantly among varieties. Total biomasses for the different varieties ranged from 56.19g to 63.33g. Stem accounted for the greatest proportion of dry matter (63.98%), followed by root (18.99%). The proportion of the dry matter accumulation in stem was highest (64.28%) in HC2, followed by V36 (64.04%). The average dry matters were 76.83% and 20.56%. in stems and leaves, respectively. The proportion of the macro- and micronutrients in kenaf parts differed significantly among varieties. Nitrogen content had the highest proportion (27.54 to 28.04%) in leaves and lowest (8.06 to 8.24%) in stem, which followed by K, Ca, P and Mg. Most of the kenaf varieties showed variation in nutrient use efficiency (NUE), respect to the measured nutrient elements. The NUE values of < 1.0 g dry matter mg-1nutrient were observed for macronutrients, whereas higher NUE values obtained for micronutrients. Total nutrient accumulation in the plant components differed among the kenaf varieties. Partitioning of dry matter and nutrients in kenaf provides a means to select better varieties and makes it possible to grow kenaf on BRIS soil using better fertilizer program

Neuropathic Changes of Osmicated Common Peroneal and Tibial Nerve in Diabetic Patients and the Related Risk Factors

      So much studies done to present the diabetic neuropathic changes of the peripheral nerves but most of them were done experimentally on laboratory animals , but little about human diabetic neuropathic and structural changes specially of large nerves like common peroneal and tibial nerve .Accordingly the present work designed to study the neuropathic changes of the tibial and common peroneal nerve samples, taken from amputated legs of 30 diabetic patients (8 females and 22 males) at age ranging between (55-75) years, and from 30 cadavers (4 females and 26 males) at age ranging between (25-50) years as control group. The teased and osmicated tibial and common peroneal nerve fibers, and histological sections taken from diabetic patients showed different deformity and Morphometrical changes, of that ; paranodal swelling, segmental demyelination, some areas with an areas of un even myelin and shortest segmentation the (common peroneal nerve 22µ and tibial nerve 265µ ) in comparison to the control group. The multiple regression analysis, showed significant effect of age of the patient and duration of diabetes on the neuropathic changes
