Many studies on the adoption of precision technologies have generally used logit models to explain the adoption behavior of individuals. This study investigates factors affecting the intensity of precision agriculture technologies adopted by cotton farmers. Particular attention is given to the role of spatial yield variability on the number of precision farming technologies adopted, using a cou...

Agricultural carbon emissions, which are the second largest source of greenhouse gas emissions in China, not only place great pressure on emission reduction but also seriously affect food security and sustainable development agriculture. As farmers direct users cultivated land main adopters agricultural technology, their adoption behavior low-carbon technology directly determines its promotion ...

This paper reviews recent literature concerning a wide range of processes through which climate change could potentially impact global-scale agricultural productivity, and presents projections of changes in relevant meteorological, hydrological and plant physiological quantities from a climate model ensemble to illustrate key areas of uncertainty. Few global-scale assessments have been carried ...

In Precision Agriculture, images coming from camera-based sensors are commonly used for weed identification and crop line detection, either to apply specific treatments or for vehicle guidance purposes. Accuracy of identification and detection is an important issue to be addressed in image processing. There are two main types of parameters affecting the accuracy of the images, namely: (a) extri...

Primary germ cell tumors of lung are extremely rare. The prognosis is usually poor, with various symptoms seriously affecting quality of life. In this paper we describe the unique case of a patient affected by an embryonal carcinoma of lung and a testicular seminoma after ten years. We also report literature about pulmonary extragonadal germ cell tumors.

The present development of precision agriculture is at the lower stage in Heilongjiang province, but it has taken effect in aspects of demonstration and extension. However there are many problems in the technology research and application, such as technology development lags, the key techniques supporting lags, the lack of “3S” technology service for agricultural application with independent in...

organizational entrepreneurship as one of the main forms of entrepreneurship has a key role in success of organizations. on the other hand, most of the research has not been considered seriously the role of social capital as the most important factor, among the various factors influencing organizational entrepreneurship development. therefore, the main purpose of this descriptive- correlative r...

This paper challenges the hypothesis that negative yield effects in key temperate grain producing regions of the world resulting from global climate change would have a serious impact on world food production. Model results demonstrate that even with concurrent productivity losses in the major grain producing regions of the world, global warming will not seriously disrupt world agricultural mar...

the present investigation was carried out to identify the factors affecting the use of information technology ‎‎(it) by trainees in apply - scientific education in agriculture. the statistical population of this study was educators ‎of agricultural apply - scientific centers. method of sampling was random multi steps sampling. questionnaire used ‎for data collection. the collected data were ana...

Nowadays laser is extensively used in various industrial, communicative, medical, and other fields. Using laser in medicine has enabled physicians to perform the most accurate and finest operations within few minutes. Non-observance of safety points during laser performance could be seriously harmful for the medical staff and the patient. Therefore, in order to prevent the possible damage of th...
