Machine for thinning flowers in gardens
02.05.2024
In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers.

Advanced Infrared Microscope
02.05.2024
Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>
Air trap for insects
01.05.2024
Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>
| Random news from the Archive A common feature of all happy couples
24.04.2024
In search of a happy and healthy relationship, couples may look to various aspects such as respect, trust and fidelity. However, scientists from Martin Luther University Halle-Wittenberg (MLU) and the University of Bamberg have found that one key trait may play an important role in relationship satisfaction: the level of power in a couple. Let's look at how this affects happiness and stability in relationships.
The study, conducted by researchers from Martin Luther University and the University of Bamberg, included a survey of 181 couples who had lived together for at least one month and had been in relationships for an average of eight years. Survey participants assessed various aspects of their relationships by filling out a questionnaire.
The results of the study showed that those couples where both partners experienced a high level of power were happy. Power was understood as the ability to influence others and avoid similar influence in the opposite direction. In the context of a couple relationship, this refers to the ability to make shared important decisions.
It turned out that an imbalanced level of power in a couple was not a major factor in relationship satisfaction. The most important thing turned out to be the personal level of power that the partner assumes from his interlocutor.
Research findings highlight the importance of power levels in relationships for achieving happiness and satisfaction. This is less a question of balance of power and more about the perception of personal power in a couple. Awareness of your own power and respect for your partner's power can contribute to a healthy, long-lasting relationship.
