The stars, in the spectrums of which C (carbon), O (oxygen), N (nitrogen), and P (phosphorus) are found, are called DNA-stars. Based on stellar abundances a new method for searching for habitable exoplanets has been developed and a list of 48 DNA-stars in the solar neighborhood, on which life is possible, has been defined. The quota of DNA-stars is equal 1.3% of the total amount of Hypatia Stellar Catalog. Only three DNA-stars out of selected 48 stars belong to the spectral class as our Sun (G2V). The closest to the solar system is the DNA-star with the number HIP 15510, which belongs to the G8V class and is 6 pc away from the solar system. Nine DNA-stars, which have the highest chemical similarity with solar spectrum, were identified. It is identified that one of these nine stars, HIP 24681, has six planets.展开更多

Adolescence is a stage of rapid growth linked to puberty affected by the nutritional transition. This study aimed to evaluate the eating habits of high school students in the district of Bamako. Methodology: The cross-sectional, descriptive study was conducted from June 15 to July 4, 2023. The sample size was calculated with the StatCalc program of the Epi 7.2 software. Data was collected using a questionnaire on KoboCollect. Analyses were performed using SPSS 26 software. Results: A total of 2400 high school students were surveyed. The average age of high school students was 16.9 years ± 1.4. The median age was 17, with extremes of 14 and 19. Of the high school students, 53.3% were boys. The sex ratio (M/F) was 1.14. About 89.4% of high school students had a Smartphone. Among high school students, 51.1% did not engage in physical activity outside of high school. Rice was the cereal most consumed by high school students (99.2%). Consumption of fish and seafood was very low (25.5%). Soft drinks were consumed on average 4.2 days/week. In addition, 60.8% of high school students consumed energy drinks. Certain eating behaviors were found in this study, such as nibbling (38.5%), eating in front of screens (79.0%), and skipping meals (46.1%). Conclusion: The most consumed cereal by high school students was rice. The consumption of ultra-processed products and sedentary leisure are habits to be monitored in the context of the prevention of food-related non-communicable diseases among high school students in the district of Bamako.展开更多

Methods A cross-sectional study was carried out on 9 378 faculty members and staff who participated in an annual health checkup at three universities selected by random cluster sampling. Demographic, anthropometric, biochemical indices and abdominal ultrasound measurements were collected. A nested case-control study was conducted with 200 NAFLD cases and 200 controls matched by gender, age (±3 years), and university. Results The overall prevalence of NAFLD was 10.3% (13.7% in males and 6.8% in females). The prevalence was significantly higher in the science and engineering university {22.1%) than in the comprehensive universities with (6.4%) and without (10.9%) medical colleges. Obesity/overweight, hyperlipidemia, diabetes mellitus, and family history of NAFLD were independently associated with higher risk of NAFLD, as were frequent consumption of desserts and salty/spicy foods. Using nutritional supplements was a protective factor against NAFLD. Intake of coarse cereals, potatoes, vegetables, fruits, and milk was significantly lower, and intake of red meat, viscera, candies and pastries, cooking oil, and total energy was significantly higher in participants with NAFLD than in controls. Conclusion Science and engineering university faculty and staff are key targets for NAFLD prevention. NAFLD is closely associated with age, gender, university type, metabolic diseases, and lifestyle/dietary habits.展开更多

Two spring wheat accessions and 44 semi-spring wheat accessions were confirmed based on their chilling days' requirement and polymorphism was found at VRN loci. The Vrn-A1 allele had the highest frequency in the RPN accessions and VA1-CAPs markers identified growth habit of RPN lines. No polymorphism was found at the VRN3 loci and some polymorphism at the region of promoter and the first intron of VRN1 was not always consistent to growth habit in the wheat RPN accessions. The existence of variation in VRN alleles suggested that singly using the dominant Vrn allele is possible to extend the diversity of wheat accessions and improve their adaption to different environments in autumn-sowing region. This information will be useful for the cultivars exploitation and wheat breeding program.展开更多

The food availability of Mongolian gazelle showed seasonal changes. The plant biomass was higher in spring and summer than that in autumn and winter. The fecal compositions of the gazelle demonstrated that fibrous parts occupied 62.4%, 74.8%, and 66.0% in spring, autumn, and winter, respectively. The Mongolian gazelle preferred to grazeCompositeae, Leguminosae, Allium spp. and other forbs in spring and autumn, while the grasses, such asAneurolepidium chinense andStipa spp. were selectively feeding in winter.展开更多

In this paper, based on the structure characteristics and XRD data, the crystal habit of BaY2F8 was analyzed. The strong bond in crystal structure of BaYEF8 was Y-FE-Y, which stretched to the shape of chain along the direction of [001]. And this was an advantaged direction for the crystal growth. The steady shapes of BaY2F8 were composed of rhombic prism { 130} and {021 }. The crystal showed an axial habit in the direction of [001]. The analysis of the crystal slice obtained by temperature gradient technique verified the above conclusion. The BaY2F8 crystal was grown by compulsive methods such as Czochralski method.展开更多

The results show that: (1) arthropodans of the orders Coleoptera, Hymenoptera and Hemiptera were major dietary components of P. frontalis; (2) coleoptera larvae always formed the predominant component of lizard diets; (3) dietary diversities of P. frontalis were not significantly different between summer and autumn or between the two sexes; (4) the similarity in trophic niches between seasons was 0.756, whereas the similarity in trophic niches between sexes was 0.994; (5) stomach content weight of lizards varied significantly among different seasons, but there was no significant difference in stomach content weight between sexes; (6) insect diversity differed significantly among the groups of the habitat with different degrees of lizard density, and the habitat with moderate lizards density had the highest insect diversity. We infer that P. frontalis prey mainly on insects and change their diet and food intake with season; males and females consumed similar preys in types and weights. As an important predator, P. frontalis could affect the insect community in the arid ecosystem of Hunshandak Desert on the Mongolian Plateau.展开更多

The leaf age, tiller growth, flowering habits, and agronomic traits of them were observed to analyze their growth habits and characteristics. The results showed that the.agronomic traits of PSR073 and PSR120, such as the plant height, panicle length, grain length, grain width, and 1000-grain weight, all acquired obvious predominance of polyploidy, and that the seed setting rate was more than 83%. No significant difference was observed between the two tetraploids and common diploids in the leaf age, tiller growth, and flowering habits. It was concluded that the characteristics of the two powerful heterosis polyploid hybrids were different from those of the polyploid rice reported earlier. Wide cross and polyploidization had no negative effects on their growth habits and characteristics; on the contrary these had powerful heterosis. This had provided theoretic and practical evidences for their application to agricultural production.展开更多

The results showed that A. cras- sispina exhibited an obvious preference on five different seaweeds, with the preference order of Betaphycus gelatinum 〉 Sargassum hemiphyllum 〉 Gelidium amansii 〉 Ulva lactuca 〉 Codium fragile. The daily feed intake of A. crassispina differed among U. lactuca, S. hemiphyllum and B. gelatinum. The feeding was affected by water temperature, seaweed species and body weight. The optimal vitality and feed intake were observed under 23 -27℃, which were inhibited under whether too higher or too lower temperature. Under the optimal temperature for feeding, the daily feed intake of adult A. crassispina assumed an exponentially-decreasing trend with increase of body weight.展开更多

That is to say, there are risks of serious problems occurring, such as suicide or mental illness, when such stress is a relatively large factor in that person’s life and they are unable to adapt thereto. Therefore, with this research, we sought to clarify the relationship between lifestyle habits and the seven stress responses of depression, anxiety, anger, emotional responses, seclusion, physical fatigue, and hyperactivity of the autonomous nervous system, and based on our results, we investigated the ways in which school nurses can support younger students who experience such psychogenic issues. The subjects of our investigation included 341 university students (123 males and 218 females). We had the subjects complete a measurement of their degrees of stress and a survey about their lifestyle habits. The results indicated that the higher the stress level, lifestyle rhythms were disturbed, especially with regards to diet, and that there were differences between males and females as well. The results also suggested that the higher the stress level, the less amount of rest. This research revealed that increased stress leads to disturbances in lifestyle habits. Some examples of ways in which school nurses can support students include creating an environment in which it is easier for younger students to talk to school nurses, conducting health consultation activities in coordination with teachers and relevant organizations, and ascertaining information regarding the circumstances of younger students. Thus, it is thought that building better lifestyle habits will make it easier to cope with stress, thereby leading to better balance in mental and physical health.展开更多

文摘Eothenomys miletus(E.miletus)is one of the rodent species found in Yunnan,and it has caused significant harm to local agricultural production.In this study,we aimed to investigate the differences in feeding habits and stomach fungi of E.miletus across different areas in the Hengduan mountain regions.By exploring the main factors affecting the feeding habits and fungi of E.miletus,this study provides a theoretical basis for the prevention and control of this species.We collected E.miletus specimens from five regions,namely Deqin,Xianggelila,Lijiang,Jianchuan,and Ailaoshan.We measured their feeding habits and the types of fungi in their stomachs using high-throughput sequencing technology.The results showed that E.miletus primarily fed on Poaceae,Oxalidaceae,Asteraceae,and Fabaceae.Food diversity of E.miletus in Ailaoshan and Jianchuan was significantly lower than in the other three regions.As for stomach fungi,Ascomycota and Basidiomycota were the absolute dominant sectors.Changes in the diversity of fungi in different regions were consistent with changes in food diversity.The diversity of fungi in Ailaoshan and Jianchuan regions was lower than in the other three regions.These findings suggest that the feeding habits of E.miletus in different regions were affected by plant species,which,in turn,affects the diversity of fungi in their stomachs.
文摘This essay articulates a new conceptual distinction-that between repertories and habits-and urges that the history of habits is the most critical unknown in the study of Chinese medical history.

文摘Objective To investigate the prevalence of nonalcoholic fatty liver disease (NAFLD) in different university categories and its association with lifestyle/dietary habits. Methods A cross-sectional study was carried out on 9 378 faculty members and staff who participated in an annual health checkup at three universities selected by random cluster sampling. Demographic, anthropometric, biochemical indices and abdominal ultrasound measurements were collected. A nested case-control study was conducted with 200 NAFLD cases and 200 controls matched by gender, age (±3 years), and university. Results The overall prevalence of NAFLD was 10.3% (13.7% in males and 6.8% in females). The prevalence was significantly higher in the science and engineering university {22.1%) than in the comprehensive universities with (6.4%) and without (10.9%) medical colleges. Obesity/overweight, hyperlipidemia, diabetes mellitus, and family history of NAFLD were independently associated with higher risk of NAFLD, as were frequent consumption of desserts and salty/spicy foods. Using nutritional supplements was a protective factor against NAFLD. Intake of coarse cereals, potatoes, vegetables, fruits, and milk was significantly lower, and intake of red meat, viscera, candies and pastries, cooking oil, and total energy was significantly higher in participants with NAFLD than in controls. Conclusion Science and engineering university faculty and staff are key targets for NAFLD prevention. NAFLD is closely associated with age, gender, university type, metabolic diseases, and lifestyle/dietary habits.

文摘With the high-quality requirements for cephalexin monohydrate,developing a robust and practical crystallization process to produce cephalexin monohydrate with good crystal habit,appropriate aspect ratio and high bulk density as well as suitable flowability is urgently needed.This research has explored the influence of ultrasound on crystallization of cephalexin monohydrate in terms of nucleation mechanism and crystal habit control.The results of metastable zone width and induction time measurement showed the presence of ultrasound irradiation can narrow the metastable zone and shorten induction time.Cavitation phenomena generated by ultrasound were used to qualitatively explain the mechanism of ultrasound promoting nucleation of cephalexin monohydrate.Furthermore,on the basis of classical nucleation theory and induction time data,a series of nucleation-related parameters(such as crystalliquid interfacial tension,radius of the critical nucleus and etc.)were calculated and showed a decreasing trend under ultrasound irradiation.The diffusion coefficient of the studied system was also determined to increase by 72.73%under ultrasound.The changes in these parameters have quantitatively confirmed the mechanism of ultrasound influence on the nucleation process.In further,the calculated surface entropy factor has confirmed that the growth of cephalexin monohydrate follows continuous growth mechanism under the research conditions of this work.Through the exploration of crystallization conditions,it is found that suitable ultrasonic treatment,seeding,supersaturation control and removal of fine crystals are conducive to improving the quality of cephalexin monohydrate product.Optimizing the crystallization process coupled continuous ultrasound irradiation with fine-crystal dissolution policy has achieved the controllable production of monodisperse cephalexin monohydrate crystal with good performance.

文摘Eighty-one wheat accessions including 50 southern regional performance nursery (SRPN) lines and 31 northern regional performance nursery (NRPN) lines from the United States were tested to evaluate the growth habit by chilling treatments and to estimate the VRN allele variation with 19 pairs of published VRN primers. Two spring wheat accessions and 44 semi-spring wheat accessions were confirmed based on their chilling days' requirement and polymorphism was found at VRN loci. The Vrn-A1 allele had the highest frequency in the RPN accessions and VA1-CAPs markers identified growth habit of RPN lines. No polymorphism was found at the VRN3 loci and some polymorphism at the region of promoter and the first intron of VRN1 was not always consistent to growth habit in the wheat RPN accessions. The existence of variation in VRN alleles suggested that singly using the dominant Vrn allele is possible to extend the diversity of wheat accessions and improve their adaption to different environments in autumn-sowing region. This information will be useful for the cultivars exploitation and wheat breeding program.
文摘The food availability, composition of the diets and selective grazing of the Mongolian gazelle (Procapra gutturosa) were studied in Hulunber Grassland in Nei Monggol. The food availability of Mongolian gazelle showed seasonal changes. The plant biomass was higher in spring and summer than that in autumn and winter. The fecal compositions of the gazelle demonstrated that fibrous parts occupied 62.4%, 74.8%, and 66.0% in spring, autumn, and winter, respectively. The Mongolian gazelle preferred to grazeCompositeae, Leguminosae, Allium spp. and other forbs in spring and autumn, while the grasses, such asAneurolepidium chinense andStipa spp. were selectively feeding in winter.
文摘The shear components of strain tensors for matrix and twin crystal of winned martensite were roughly opposite after calculation,and the strain energy would be reduced.The growth of martensitic plates along the normal direction of the twin plane may depend upon the effect of self-accommodation between the matrix and twin crystals.Based upon the analysis on the displacement vectors of the normals for different habit planes,the{10,3,15}_f plane could form the macroscopic invariant habit plane;but the(55)_f,(22)_f,and(11)_f planes are difficult to become the invariant planes.

文摘BaY2F8 crystals had a relatively low symmetry, and its XRD data showed that those strong diffractions occured in a narrow angle range, so it was difficult to orientate the single crystals of BaYEFs. In this paper, based on the structure characteristics and XRD data, the crystal habit of BaY2F8 was analyzed. The strong bond in crystal structure of BaYEF8 was Y-FE-Y, which stretched to the shape of chain along the direction of [001]. And this was an advantaged direction for the crystal growth. The steady shapes of BaY2F8 were composed of rhombic prism { 130} and {021 }. The crystal showed an axial habit in the direction of [001]. The analysis of the crystal slice obtained by temperature gradient technique verified the above conclusion. The BaY2F8 crystal was grown by compulsive methods such as Czochralski method.

文摘We examined the dietary diversity and food intake of Phrynocephalus frontalis, compared the difference of insect diversity in the natural habitats with different lizard densities, and discussed the potential role of this lizard in the desert ecosystem. The results show that: (1) arthropodans of the orders Coleoptera, Hymenoptera and Hemiptera were major dietary components of P. frontalis; (2) coleoptera larvae always formed the predominant component of lizard diets; (3) dietary diversities of P. frontalis were not significantly different between summer and autumn or between the two sexes; (4) the similarity in trophic niches between seasons was 0.756, whereas the similarity in trophic niches between sexes was 0.994; (5) stomach content weight of lizards varied significantly among different seasons, but there was no significant difference in stomach content weight between sexes; (6) insect diversity differed significantly among the groups of the habitat with different degrees of lizard density, and the habitat with moderate lizards density had the highest insect diversity. We infer that P. frontalis prey mainly on insects and change their diet and food intake with season; males and females consumed similar preys in types and weights. As an important predator, P. frontalis could affect the insect community in the arid ecosystem of Hunshandak Desert on the Mongolian Plateau.
文摘Based on a series of polyploid indica-japonica hybrid plant lines obtained from a new breeding strategy of using double predominance of wide cross and polyploidization to breed super flee, two polyploid indica-japonica hybrids, PSR073 and PSR120 were studied in their growth periods to show the powerful heterosis in a larger scale and to study the characteristics of polyploid indica-japonica hybrids more elaborately. The leaf age, tiller growth, flowering habits, and agronomic traits of them were observed to analyze their growth habits and characteristics. The results showed that the.agronomic traits of PSR073 and PSR120, such as the plant height, panicle length, grain length, grain width, and 1000-grain weight, all acquired obvious predominance of polyploidy, and that the seed setting rate was more than 83%. No significant difference was observed between the two tetraploids and common diploids in the leaf age, tiller growth, and flowering habits. It was concluded that the characteristics of the two powerful heterosis polyploid hybrids were different from those of the polyploid rice reported earlier. Wide cross and polyploidization had no negative effects on their growth habits and characteristics; on the contrary these had powerful heterosis. This had provided theoretic and practical evidences for their application to agricultural production.

文摘Abstract Employing experimental-ecological methods, the feeding and vitality of adult Anthocidaris crassispina were investigated. The results showed that A. cras- sispina exhibited an obvious preference on five different seaweeds, with the preference order of Betaphycus gelatinum 〉 Sargassum hemiphyllum 〉 Gelidium amansii 〉 Ulva lactuca 〉 Codium fragile. The daily feed intake of A. crassispina differed among U. lactuca, S. hemiphyllum and B. gelatinum. The feeding was affected by water temperature, seaweed species and body weight. The optimal vitality and feed intake were observed under 23 -27℃, which were inhibited under whether too higher or too lower temperature. Under the optimal temperature for feeding, the daily feed intake of adult A. crassispina assumed an exponentially-decreasing trend with increase of body weight.
文摘Many psychogenic issues trigger issues in children, such as refusal to attend school or bullying. That is to say, there are risks of serious problems occurring, such as suicide or mental illness, when such stress is a relatively large factor in that person’s life and they are unable to adapt thereto. Therefore, with this research, we sought to clarify the relationship between lifestyle habits and the seven stress responses of depression, anxiety, anger, emotional responses, seclusion, physical fatigue, and hyperactivity of the autonomous nervous system, and based on our results, we investigated the ways in which school nurses can support younger students who experience such psychogenic issues. The subjects of our investigation included 341 university students (123 males and 218 females). We had the subjects complete a measurement of their degrees of stress and a survey about their lifestyle habits. The results indicated that the higher the stress level, lifestyle rhythms were disturbed, especially with regards to diet, and that there were differences between males and females as well. The results also suggested that the higher the stress level, the less amount of rest. This research revealed that increased stress leads to disturbances in lifestyle habits. Some examples of ways in which school nurses can support students include creating an environment in which it is easier for younger students to talk to school nurses, conducting health consultation activities in coordination with teachers and relevant organizations, and ascertaining information regarding the circumstances of younger students. Thus, it is thought that building better lifestyle habits will make it easier to cope with stress, thereby leading to better balance in mental and physical health.
