in this study, hydraulic properties of low pressure drip irrigation systems were studied under laboratory conditions and using of the pipes that exist in iran. therefore, effect of various heads from 0.45 to 1.8m was evaluated for lateral pipe with outside diameter 32mm and length of 16, 30, 60 and also the lateral pipe with length 16 and outside diameter of 16, 20, 25 and 32mm, on hydraulic ch...

s: Assessment of Publication Bias In addition to the fully-published reports of head-to-head trials cited above, we found three studies that were published in abstract format only, at the time of writing (see Table 7). Two of these may be interim analyses of included studies, and do not present enough data to compare to published studies. 58 One study appears to be independent of the included s...

OBJECTIVE To investigate effects of pediatric head trauma on parent mental health, parent-child relationship and family functioning 2 weeks after discharge. METHODS Ninety-seven mothers and 37 fathers of 106 preschool children hospitalized with head injury completed Mental Health Inventory (MHI), Parenting Stress Index, Family Adaptability and Cohesion Evaluation Scales II (FACES II) and Mult...

Abstract: The study analyzes the flow over bottom racks made of longitudinal T-shaped bars. A clear water flow is considered in a laboratory flume. Free surface profiles, wetted rack lengths, and discharge coefficients are measured, changing parameters such as longitudinal slope, void ratio, and approaching flow. The present work complements existing experimental studies, considering the influe...

Most patients presenting to the emergency department with minor head injuries are discharged with written information. Here the quality of minor head injury discharge leaflets in the Republic of Ireland is evaluated against a nationally accepted template. There was great variability in leaflet content. Most provided minimal information on emergency symptoms but 60% contained no information on p...

Most head injured patients arrive in the accident and emergency (A&E) department within a few hours of the injury. This article concerns the investigation of a group that has received less attention: those whose first attendance is delayed, who reattend, or develop complications after a period of observation. Delay in the initial presentation or unplanned return to the A&E department after head...

The lexical acquisition system presented in this paper incrementally updates linguistic properties of unknown words inferred from their surrounding context by parsing sentences with an HPSG grammar for German. We employ a gradual, informationbased concept of “unknownness” providing a uniform treatment for the range of completely known to maximally unknown lexical entries. “Unknown” information ...

Layer 3 of the medial entorhinal cortex is a major gateway from the neocortex to the hippocampus. Here we addressed structure-function relationships in medial entorhinal cortex layer 3 by combining anatomical analysis with juxtacellular identification of single neurons in freely behaving rats. Anatomically, layer 3 appears as a relatively homogeneous cell sheet. Dual-retrograde neuronal tracing...

Traditional meter gates for farm delivery flow measurement from an open channel conveyance have traditionally incorporated round canal gates (Armco type) for control. In recent years, some irrigation water agencies (i.e., irrigation districts) have replaced deteriorating round gates with lower-cost rectangular gates that cover round holes. Similar to the situation described in a companion paper...

BACKGROUND Allergic reactions to the metal head-pins of a head fixation holder are rare. CASE DESCRIPTION A 45-year-old woman was referred to our hospital for the treatment of unruptured cerebral aneurysms. She underwent successful surgical treatment using four head-pins of the Sugita frame. At her first outpatient visit 3 weeks after discharge, redness, sores, and focal hair loss were noted ...
