the part of precipitation that directly meets the water requirements of a plant, is termed the effective rainfall. effective rainfall estimation methods consist of: direct measurement, empirical methods, and soil-water balance modeling. due to the high costs of measurements and storing devices such as lysimeter, empirical and balance methods are most commonly used to estimate the effective rain...

We reanalyze some of the data used by Klots to establish an experimental basis for the claim by Gspann that clusters have a highest temperature in molecular beams. The value of this temperature is given by the evaporative activation energy and a dimensionless parameter, called the Gspann parameter. The value of the Gspann parameter we derive from the data is higher than the value found by Klots...

Tree balance plays an important role in different research areas like theoretical computer science and mathematical phylogenetics. For example, it has long been known that under the Yule model, a pure birth process, imbalanced trees are more likely than balanced ones. Therefore, different methods to measure the balance of trees were introduced. The Sackin index is one of the most frequently use...

BACKGROUND Balancing the personal and the professional is an ongoing struggle for most professionals, and palliative care clinicians are no exception. A sustained lack of balance can lead to feelings of frustration, inadequacy, and guilt. Palliative care physicians may find this balance particularly difficult due to the nature of their work: caring for patients and families who are often suffer...

BACKGROUND Benzodiazepines and related drugs affect physical functioning negatively and increase fall and fracture risk. As impaired muscle strength and balance are risk factors for falls, we examined the effects of hypnotic withdrawal on handgrip strength and balance in older adult outpatients during and after long-term use of temazepam, zopiclone and zolpidem (here collectively referred to as...

Background: Multiple sclerosis (MS) is a chronic disease characterized by degradation of the central nervous system myelin which may impair the balance of patients. Core Stability Exercises have been the focus of attention for repairing the stability of some patients.   Objectives: To assess the effect of core stability exercise on the balance of patients with multiple sclerosis. ...

INTRODUCTION Visual stimuli can induce vestibular adaptation and recovery of body balance. OBJECTIVE To verify the effect of visual stimuli by digital images on vestibular and body balance rehabilitation of peripheral vestibular disorders. METHODS Clinical, randomized, prospective study. Forty patients aged between 23 and 63 years with chronic peripheral vestibular disorders underwent 12 se...

background: multiple sclerosis (ms) is a neurological disease with a variety of signs and symptoms. exercise therapy has been shown to improve physical functions in ms. however, questions about an optimal exercise therapy remain. in this regard, we suggest a combined exercise therapy including aerobic and resistance exercises for ms patients. the study is designed to observe, test and compare t...

The timing of the disappearance of the snow cover in spring, or snow melt day (SMD), is a key parameter controlling the carbon dioxide balance between the northern mire and heath ecosystems and the atmosphere. We present a simple method for the determination of the SMD using a satellite-based surface albedo product (SAL). The method is based on the local change of albedo from higher wintertime ...
