The commonly used cut-off values for identifying iron deficiency are extrapolated from older children and may not be suitable for infants. Therefore, our study aimed to establish appropriate cut-off values for the evaluation of iron status in Chinese infants. Pregnant women who delivered at 〉37 gestational weeks with normal iron status were recruited. Later, infants with normal birth weight and who were breastfed in the first 4 months were selected. Blood samples were collected to assess hemoglobin, serum ferritin, soluble transferrin receptor, mean corpuscular volume and free erythrocyte protoporphyrin. Cut-offs of all iron indices were determined as the limit of 95% confidence interval.展开更多

文摘Iron deficiency anemia is one of the most prevalent nutritional deficiency worldwide. The commonly used cut-off values for identifying iron deficiency are extrapolated from older children and may not be suitable for infants. Therefore, our study aimed to establish appropriate cut-off values for the evaluation of iron status in Chinese infants. Pregnant women who delivered at 〉37 gestational weeks with normal iron status were recruited. Later, infants with normal birth weight and who were breastfed in the first 4 months were selected. Blood samples were collected to assess hemoglobin, serum ferritin, soluble transferrin receptor, mean corpuscular volume and free erythrocyte protoporphyrin. Cut-offs of all iron indices were determined as the limit of 95% confidence interval.

文摘Herein,the association between the dynamic adsorption capacity of toluene and several important characteristic values on activated carbon(AC)samples was investigated by multidimensional linear regression.Among the characteristic values,the carbon tetrachloride(CTC)adsorption value has demonstrated relatively stronger correlation with the toluene adsorption capacity on AC sampleswith diverse sources and forms,particularly in exposure to high-concentration toluene.Notably,the relevance of the toluene adsorption capacity to the CTC value could also be extended to a series of other porous adsorbents,which proved the wide applicability of CTC value in characterizing the adsorption behaviors.Based on these results,a mathematical and visual model was then established to predict the toluene adsorption saturation under different conditions(inlet concentration,adsorption time,initial CTC value,etc.)on diverse AC samples,of which the accuracy has later been verified by experimental data.As such,a fast and accurate estimation of the adsorption behaviors over AC samples,and possibly other porous adsorbents,was realized.

文摘Throughout this work,we explore the uniqueness properties of meromorphic functions concerning their interactions with complex differential-difference polynomial.Under the condition of finite order,we establish three distinct uniqueness results for a meromorphic function f associated with the differential-difference polynomial L_(η)^(n)f=Σ_(k=0)^(n)a_(k)f (z+k_(η))+a_(-1)f′.These results lead to a refined characterization of f (z)≡L_(η)^(n)f (z).Several illustrative examples are provided to demonstrate the sharpness and precision of the results obtained in this study.
文摘With the continuous and in-depth advancement of higher education reform,the employment issue of college graduates has become a hot topic of discussion in current colleges and universities.In order to cultivate the professional values of college students,colleges and universities need to strengthen the implementation of policies and measures for youth employment and optimize guidance and services for employment and entrepreneurship.Guide college graduates to rationally plan their academic and career development,improve their overall employment quality and practical ability,and then closely integrate their career planning with the development of the country and society.In this regard,we will focus on“strengthening career education to guide college graduates to establish correct career values.”
文摘The objective of the study is to examine the moderating influence of gender on the relationship between cultural values and Islamic work ethics(IWE)among Palestinian Arab high school teachers in Israel who represent an ethnic and religious minority within a Western-oriented framework.The study sample comprised 1,245 Arab teachers(759 females and 476 males).Data analysis was conducted using structural equation modeling with AMOS,focusing on path analysis.The research findings highlight a substantial relationship between cultural values and Islamic work ethics,with gender as a moderating variable.Additionally,the results indicate a significant positive relationship between the cultural value dimension of uncertainty avoidance and both dimensions of Islamic work ethics-dedication and social responsibility in the workplace,along with independence,diligence,and achievement.In contrast,a pronounced and significant negative relationship was identified between the cultural dimension of femininity/masculinity and these two dimensions of Islamic work ethics.

文摘Medical isotopes are the foundation material for nuclear medicine and are primarily produced through in-reactor irradia-tion.Neutron spectrum regulation is the main technical approach for enhancing the production of medical isotopes,and it requires determining the optimal neutron spectrum and quantifying the values of neutrons in different energy regions.We calculated the neutron energy region values for 20 medical isotopes(^(14)C,^(32)P,^(47)Sc,^(60)Co,^(64)Cu,^(67)Cu,^(89)Sr,^(90)Y,^(99)Mo,^(125)I,^(131)I,^(153)Sm,^(161)Tb,^(166)Ho,^(177)Lu,^(186)Re,^(188)Re,^(92)Ir,^(225)Ac,and ^(252)Cf).The entire energy range was divided into 238 energy regions to improve the energy spectrum resolution,and both fast and thermal reactors were simulated to enhance universal applicability.A dataset of neutron energy region values across the entire energy range was built,which identifies the positive and negative-energy regions and guides the neutron spectrum regulation process during in-reactor medical isotope produc-tion.We conducted neutron spectrum regulation based on this dataset,which effectively improved the production efficiency of medical isotopes and demonstrated the correctness and feasibility of the dataset.
文摘This comparative study examines cultural empathy strategies employed by two major international broadcasters-BBC(British Broadcasting Corporation)and CGTN(China Global Television Network)-in their efforts to balance local emotional resonance with universal values in global communication.Through a mixed-methods approach combining content analysis of 2,400 news reports,interviews with 32 media professionals,and audience reception studies across 15 countries,this research investigates how international media organizations navigate the complex terrain of cross-cultural communication in an increasingly interconnected world.The findings reveal significant differences in empathy strategies:BBC employs a“universalist-localized”approach emphasizing shared human experiences while maintaining Western liberal values,achieving 67.3%cross-cultural resonance scores,while CGTN adopts a“particularist-global”strategy highlighting cultural diversity within a framework of mutual understanding,achieving 61.8%resonance scores.Both organizations face challenges in balancing authentic cultural representation with audience accessibility,managing 73.4%and 68.9%cultural authenticity ratings respectively.The study identifies five key empathy strategies:narrative localization,cultural bridging,emotional universalization,value harmonization,and contextual adaptation.Results indicate that successful cultural empathy requires sophisticated understanding of target audiences’cultural schemas while maintaining editorial authenticity.The research contributes to international communication theory by proposing a Cultural Empathy Framework(CEF)that explains how media organizations can effectively navigate the tension between local emotions and universal values in global broadcasting contexts.
