welsh onion (allium fistulosum l.) is one of the important vegetable crops in china. however, the seeds of this crop are short-lived and their vitality tends to be easily lost in the course of storage. the present study was conducted to elucidate the effects of welsh onion seed priming with potassium nitrate (kno3) on seed vigor and on other such related mechanisms during twelve months of stora...

Test exploitation equipment and technology have progressed considerably in marine natural gas hydrate (NGH) exploitation, but many critical technical issues still need to be resolved before commercial production. Previous studies proposed a non-drilling device—a self-entry device (SEED)—but reaching the NGH threshold its initial state is difficult. Consequently, we verified evaluated some produ...

Oil palm (Elaeis guineensis Jacq.) is the highest oil-yielding plant in the world, storing 90 and 60% (dry weight) oil in its mesocarp and kernel, respectively. To gain insights into the oil accumulation mechanism, one of the key enzymes involved in triacylglycerol (TAG) biosynthesis, a Type 2 diacylglycerol acyltransferase (DGAT2) from oil palm, was characterized for its in vivo activity. EgDG...

Histogram equalization (HE) is one of the simplest and most effective techniques for enhancing gray-level images. For color images, HE becomes a more difficult task, due to the vectorial nature of data. We propose a new method for color image enhancement that uses two hierarchical levels of HE: global and local. In order to preserve the hue, equalization is only applied to intensities. For each...

This paper reports a sensitive method with electrochemical technique to detect various proteases, which can be used for the diagnosis of prostate cancer. For the proposed assay method, the working electrode is modified with the peptide probes for the target proteases. These probes contain the substrate sequence of target proteases, as well as the seed peptide sequence that can accelerate the mi...

Seed heteromorphism provides plants with alternative strategies for survival in unfavourable environments. However, the response of descendants from heteromorphic seeds to stress has not been well documented. Suaeda aralocaspica is a typical annual halophyte, which produces heteromorphic seeds with disparate forms and different germination characteristics. To gain an understanding of the salt t...

This study was conducted to examine the effect of low doses of X-rays on date palm (Phoenix dactylifera L., cv. Khalas) seed germination and seedling growth. A significant reduction in seed germination was observed in response to X-irradiation as compared to the non-irradiated control. A significant reduction in seed germination percentage (82.85%) began at 0.25 Gy of X-rays and persisted to de...

[1] Recent experimental evidence indicates that heterogeneous chemical reactions play an important role in the gas-particle partitioning of organic compounds, contributing to the formation and growth of secondary organic aerosol in the atmosphere. Here we present laboratory chamber studies of the reactive uptake of simple carbonyl species (formaldehyde, octanal, trans,trans-2,4-hexadienal, glyo...

In present studies several attempts have been made to reduce the amount of trypsin and chymotrypsin inhibitors in winged bean (Psophocarpus tetragonolobus) mutants developed through induced mutation. The low seed TI (trypsin inhibitor) lines comprised long pod-5 and long pod-2 mutant lines. The low tuber TI feature could be noted in the mutant population. Such lines were long pod-5, large leaf/...

The present study investigated comparatively the impact of two types of input enhancement (i.e. textual vs. compound enhancement) on developing grammar ability in Iranian EFL setting. Sixty-five female secondary high school students were selected as a homogenous sample out of about a 100-member population based on Nelson language proficiency test. Then, their grammar ability was measured based ...
