Potato has been widely planted, and China’s potato planting area and total output have become the first in the world. As an important part of the whole mechanization technology, potato planting mechanization directly affects the quality and yield of potato. As the core component of potato planter, the performance of seed metering device directly affects the operation quality of planter. In recent years, with the continuous efforts of researchers and manufacturers at home and abroad, the types and research technology of seed metering device are constantly innovating and improving. This paper mainly introduces the key technologies and types of seed metering devices used in the main models in China and abroad, as well as the existing problems and future development direction of different types of seed metering devices.

In this paper, we discuss a series of ce3+ co doped di calcium magnesium di silicate phosphors were synthesized by high temperature solid state reaction method. Thermoluminescence properties of prepared sample also investigated. Their kinetic parameters [activation energy (E), frequency factor (s) and order of the kinetics (b)] of these phosphors were evaluated and compared using the peak shape method. FractoMechno- luminescence properties Ca2MgSi2O7: Eu2+ and Ca2MgSi2O7: Ce3+, Eu2+ phosphors. Their ML properties showed that when Ca2MgSi2O7: Eu2+ phosphor is co doped with Ce3+, ML intensity was more (strongly) enhanced and their mechanoluminescence intensities of Ca2MgSi2O7: Eu2+ and Ca2MgSi2O7: Eu2+, Ce3+ phosphors increased proportionally increased with the increase in impact velocity, which suggests that these phosphors can be used as mechnoluminescent display device such as fracture sensor, impact sensor, damage sensors, safety management monitoring system etc .

COVID-19 outbreak has been a serious threat and it has been reported with different presentations and complications, here we report a 39 year old healthy male who presented with respiratory symptoms and investigation revealed that he is positive for SARS-CoV-2 and work up for Leukocytosis confirmed the diagnosis of CML.

Introduction: Through studies in the scientific literature about the measurement of sounds in the Intensive Care Unit environment, it is clear that the noise, continuous sound of equipment and those caused by the health team itself is excessive and above 85dB (decibels), favors increased sensitivity of patients to pain, irritation, post-traumatic stress and may cause psychomotor agitation, delirium, changes in heart rate and sleep. A peaceful environment can bring countless benefits to restoring the health of patients, as well as reducing the stress of professionals. Objective: To analyze some research and studies published in Brazil about the noise in an Intensive Care Unit and the perception that professionals have about this topic. Methods: A systematic literature review was performed with electronic search of articles indexed in PePSIC and SciELO databases, published from 2009 to 2019, in which the inclusion and exclusion criteria were considered. Results: indicate that the noise in this type of place often presents with an oscillating intensity of moderate to intense. It is verified that there is from the professionals a certain level of understanding of the existence of noise in the ICU. Considerations: Despite the finding by professionals about noise, it is also observed that there are few current publications about the awareness of health professionals regarding the importance of preserving a quieter environment and criteria that reinforce effective humanization interventions during the study. postoperative period of cardiac surgery in this type of environment.

The use of medicinal plants and probiotics has recently gained interest since the ban on the use of antibiotics as growth promoters by the European Union in 2006. They are new alternatives to bridge the gap between food safety and production. Medicinal plants are cheaper and loaded with several minerals, vitamins and phytochemicals such as: alkaloids, saponin, flavonoids, phenols, tannins etc. which allows them to perform multiple biological activities. Probiotics on the other hand, repopulates the gastro intestinal tracts (GIT) with beneficial bacteria which controls the action of pathogens and control their population, thereby reducing mortality and improving general performance of an animal.

Knowing Diabetes Mellitus, as well as its main characteristics is a means of prevention. From this perspective, this chapter aims to analyze the main characteristics about Diabetes Mellitus, taking as an approach the general aspects that involve epidemiology, costs, correlation with arterial hypertension, in addition to Gestational Diabetes.

Introduction: The Intensive Care Unit is a hospital location permeated by not very positive associations, with the multidisciplinary team having to deal with the pain, fears and anxiety of their patients daily and the demands of their families for comprehensive care and less suffering for the patient. Pain is a reaction of the patient with biopsychosocial factors involved. The team does not always act successfully in the face of the patient’s pain, using the psychologist as a mediator of this situation. Objective: to reflect on the role of the psychologist in the face of the patient’s pain in the Intensive Care Unit. Methodology: experience report. Results and discussion: In the intensive care unit, the patient is distant from his family members, without clothes, with monitoring of different equipment and people, with invasive care, which can be felt as threatening his integrity. Pain is an unpleasant sensory experience that may be associated with tissue damage or not. It is a difficult phenomenon to be measured, since it can be an emotional pain, activated by psychological components or not. Each person has a different intensity, manifestation and reaction to pain. There are pain scales that can be used as a strategy to adapt the best intervention in different contexts of illness. The psychologist in this unit acts focused on the patient, his family and team, because everyone involved may be interfering in the recovery process and in the experience of pain and in its coping. In this triad, attentive, neutral listening should be offered to provide psychological support and to facilitate the mediation of these relationships. Conclusion: This study points to the need to study more about the pain process in the ICU context, the role of the psychologist and the importance of humanization in this context.

Air pollution in cities and urban sectors are increasing significantly on a time scale at global level. This alarming fact is substantiated with its gravity in the sense that more than 80% of people living in urban areas are exposed to air quality levels that exceed the World Health Organization (WHO) limits. The situation world over is more critical to populations in low – income cities which are most impacted. According to the urban air quality database, 98% of cities in low – and middle income countries with more than 100 000 inhabitants do not meet WHO air quality guidelines. However, the cities in high – income countries this percentage decreases to 56%. The WHO reveals the fact that around 3000 cities in 103 countries have started measuring air pollution levels and recognizing the associated health impacts. With declines of urban air quality, the risk of stroke, heart disease, lung cancer, chronic and acute respiratory diseases, including asthma, increases for the people who live in these cities. An effort has therefore been made by the authors in this paper to explain briefly some of the relevant factors responsible for urban air pollution such as heat island effect, albedo effect, urban planning with environmental inputs, climate change, urban environment policy parameters, sustainable urban transport, environmental sustainability etc. These issues need to be addressed globally on high scientific scale for effective reduction of urban air pollution.

Greenhouse and field experiments were conducted to test the effectiveness of biofertilizers on switchgrass (Panicum virgatum) yields compared to inorganic fertilizer and a zero-control. In the greenhouse, Variovorax paradoxus JM63, JumpStart® (Penicillium bilaii), inorganic fertilizer and control treatments resulted in significantly higher per L pot biomass yields compared to the control treatment; 2.74 (±0.24), 2.55 (±0.10), 2.52 (±0.24) and 1.34 (±0.09) g L-1, respectively. As JumpStart® is a commercially available biofertilizer, it was used in the field experiment along with inorganic and control treatments. All three treatments were applied to established (2014) switchgrass plots. Significantly (p

The seeds availability and quality are the main constraints for agricultural explosion of plantain productivity in sub-Saharan Africa countries. Plantain vivoplants were generated and submitted to different treatments in the nursery, the plant responses were analysed and compared in other to determine the best treatment influencing the growth promotion and induced resistance to Mycosphaerella fijiensis. Plantain explants and vivoplants were treated with five different treatments: clam shells powder (T1), clam shells and Tithonia diversifolia powder (T2), Tithonia diversifolia flakes (T3), Tithonia diversifolia mulch (T4), Tithonia diversifolia liquid extract (T5). The treatments were applied by their incorporation in the substrate (T1, T2, T3 and T4) or by watering of the whole plant (T5). The germination rate was evaluated and recorded in the greenhouse at the germination and pre-emergence stage, followed by the agromorphological measurements on the vivoplants and their inoculation with Mycosphaerella fijiensis in the shade at the vegetative growth stage. Biochemical analysis was done on the vivoplants leaves tissues. The vivoplants respond positively to all the treatments by a quick germination and emergence, coupled with an important biomarker’s accumulation (total proteins and phenolics). It turns out that the best treatment was T5 (T. diversifolia liquid extract), followed by T4 (T. diversifolia mulch). However, depending on the expected response in the vivoplants, all these treatments have proven to be impactful. Therefore, a combination of Tithonia diversifolia liquid extract (T5) with clams’ shells (T1) could be useful to boost the production at low cost and without chemical inputs of large amount of improved vigorous (clean and less susceptible) planting material, impacting thus the food security and poverty alleviation.
