We present, in this paper, our contribution in SemEval2017 task 4 : ”Sentiment Analysis in Twitter”, subtask A: ”Message Polarity Classification”, for English and Arabic languages. Our system is based on a list of sentiment seed words adapted for tweets. The sentiment relations between seed words and other terms are captured by cosine similarity between the word embedding representations (word2...

The free distribution of seeds and tools is the standard approach to agricultural recovery. The predominance of this approach is partly attributable to the: (1) perception that farmer seed quality is poor, (2) insistence on seed certification, (3) promotion of researcher varieties, (4) misdiagnosis of unavailability, (5) difficulty accessing farmer seed, and (6) support for the commercial seed ...

to investigate the relationship between different traits, discover factors affecting this relationship and to identify components of seed yield in cultivated and wild safflower genotypes, this investigation was conducted at isfahan university of technology research farm under two different water regimes during 2008. significant differences were observed between genotypes belonged to the two spe...

Mechanization and simplification are inevitable trends in agriculture production to decrease input demands and simultaneously improve resource use efficiency. Dry direct-seeded rice is a resource-saving cropping system and has been considered as a replacement for traditional transplanted rice. However, the poor establishment of dry direct-seeded early rice, primarily induced by chilling stress,...

Somaclonal variation is one of the possible sources of variation in plant breeding. To evaluate the usefulness of somaclonal variation for creating variation in Iranian cultivars of wheat, proteins, enzymes and chromosome number of regenerated and seed-produced plants of wheat (Alamout, Hyrmand and Maroon) were studied. Plantlets obtained from the immature embryos and seed culture were collecte...

this study was carried out to determine the effect of seed growing regions and loading speed on some mechanical properties of castor seed. these properties are used to design and improve related machines such as expeller that are used for extraction of oil from castor seed. mechanical properties of castor seed were expressed in terms of rupture force and energy, bio-yield force, apparent modulu...

Turbulence is believed to play important roles in the origin of cosmic magnetism. While it is well known that turbulence can efficiently amplify a uniform or spatially homogeneous seed magnetic field, it is not clear whether or not we can draw a similar conclusion for a localized seed magnetic field. The main uncertainty is the rate of magnetic field diffusion on scales larger than the outer sc...

Ghana’s seed sector has undergone some significant changes in the past few years, including the establishment of a new seed law and regulations, the appointment of a National Seed Council, and the emergence of a more diversified commercial seed sector. This paper begins by reviewing the principal elements in Ghana’s commercial seed sector. It then examines three factors that will be critical to...

Double direct-seeding for double rice cropping is a simplified, labor saving, and efficient cropping system to improve multiple-crop index and total rice production in central China. However, poor crop establishment of direct-seeded early rice due to chilling stress is the main obstacle to wide spread of this system. A series of experiments were conducted to unravel the effects of pre-sowing se...
