微生物可通过诱导形成磷酸盐沉淀来固定土壤中的有效态铅(Pb),在Pb污染土壤修复方面越来越受到人们的重视,但对其诱导的磷酸盐沉淀在土壤中的活性变化特征缺乏了解。研究了1株拉恩氏菌LRP3对单一Pb和Cu-Pb复合磷酸盐沉淀的诱导作用,并通过土壤培养和盆栽试验研究了2种磷酸盐沉淀中的Pb在土壤中的释放及小白菜对其吸收特征。结果表明:菌株LRP3发酵液能够快速去除溶液中单一或与Cu^(2+)共存的Pb^(2+),分别诱导形成呈不规则块状的Pb(H_(2)PO_(4))_(2)晶体和小球形的Pb(H_(2)PO_(4))_(2)-Cu_(3)(PO_(4))_(2)复合晶体。短时土壤培养条件下,复合晶体中的Pb稳定性高,不易活化,而单一晶体中的Pb稳定性较差,容易活化,土壤微生物能够促进其活化。单一和复合磷酸盐晶体可在小白菜根际土壤中释放出Pb,增加小白菜叶子和根中Pb的含量,与对照土壤相比,小白菜叶子和根对Pb的富集系数分别下降了62.50%,78.75%和75.50%,83.75%。因此,菌株LRP3在Pb污染土壤修复方面有重要的应用价值,并且可通过向土壤中添加Cu^(2+)来强化修复效果。

In this paper we examine several definitions of vaccine efficacy(VE)that we found in the literature,for diseases that express themselves in outbreaks,that is,when the force of infection grows in time,reaches a maximum and then *** fact that the disease occurs in outbreaks results in several problems that we *** propose a mathematical model that allows the calculation of VE for several *** trials usually needs a large number of volunteers that must be ***,all volunteers should be enrolled in approximately the same time,but this is generally impossible for logistic reasons and they are enrolled in a fashion that can be replaced by a continuous density function(for example,a Gaussian function).The outbreak can also be replaced by a continuous density function,and the use of these density functions simplifies the ***,for example Gaussian functions,one of the problems one can immediately notice is that the peak of the two curves do not occur at the same *** model allows us to conclude:First,the calculated vaccine efficacy decreases when the force of infection increases;Second,the calculated vaccine efficacy decreases when the gap between the peak in the force of infection and the peak in the enrollment rate increases;Third,different trial protocols can be simulated with this model;different vaccine efficacy definitions can be calculated and in our simulations,all result are approximately the *** final,and perhaps most important conclusion of our model,is that vaccine efficacy calculated during outbreaks must be carefully examined and the best way we can suggest to overcome this problem is to stratify the enrolled volunteer's in a cohort-by-cohort basis and do the survival analysis for each cohort,or apply the Cox proportional hazards model for each cohort.

Localized-states quantum confinement induced by roughness in CdMnTe/CdTe heterostructures grown on Si(111) substrates

引用

Journal of Semiconductors 2024年第9期 34-42页

作者： Leonarde do Nascimento Rodrigues Wesley Fiorio lnoch Marcos L.F.Gomes Odilon D.D.Couto Jr. Bráulio S.Archanjo Sukarno Olavo Ferreira Physics Department Federal University of Vi?osa Instituto de Física Gleb Wataghin Universidade Estadual de Campinas National Institute of Metrology Quality and Technology (Inmetro) Materials Metrology Division (DIMAT)

This work shows that despite a lattice mismatch of almost 20%, CdMnTe/CdTe/CdMnTe heterostructures grown directly on Si(111) have surprisingly good optical emission properties. The investigated structures were grown by molecular beam epitaxy and characterized by scanning transmission electron microscopy, macro-and micro-photoluminescence. Low temperature macro-photoluminescence experiments indicate three emission bands which depend on the CdTe layer thickness and have different confinement characteristics. Temperature measurements reveal that the lower energy emission band (at 1.48 eV)is associated to defects and bound exciton states, while the main emission at 1.61 eV has a weak 2D character and the higher energy one at 1.71 eV has a well-defined (zero-dimensional, 0D) 0D nature. Micro-photoluminescence measurements show the existence of sharp and strongly circularly polarized (up to 40%) emission lines which can be related to the presence of Mn in the heterostructure. This result opens the possibility of producing photon sources with the typical spin control of the diluted magnetic semiconductors using the low-cost silicon technology.

微生物可通过诱导形成碳酸盐沉淀来固定土壤中的有效态Pb,在Pb污染土壤修复方面越来越受到人们的重视。通过对1株侧孢短芽孢杆菌ZN5的氨化和硝酸盐同化发酵液对土壤中Pb的碳酸盐固定作用,及其诱导的碳酸盐沉淀在土壤中的稳定性进行研究。结果表明:菌株ZN5的氨化和硝酸盐同化发酵液使土壤可交换态Pb含量分别降低20.28%和17.38%,有机物结合态Pb含量占比分别降低5.65%和3.76%,残渣态Pb含量占比分别降低4.28%和2.35%,碳酸盐结合态Pb比例分别增加28.93%和21.92%,铁锰氧化物结合态Pb含量占比分别增加1.17%和0.66%,导致土壤有效态Pb含量分别降低了71.50%和62.30%,从而使得小白菜在Pb含量为980.77 mg/kg的重污染土壤中能够正常生长。菌株ZN5通过氨化和硝酸盐同化过程诱导的2种含Pb碳酸盐沉淀加入到土壤中,即使土壤总Pb含量约500 mg/kg,小白菜的生长虽然受到一定的影响,但对Pb的富集系数有大幅度地下降。说明菌株ZN5可通过氨化和硝酸盐同化过程诱导形成含Pb碳酸盐沉淀来固定土壤中的有效态Pb,从而降低Pb对小白菜的毒性,并且通过硝酸盐同化过程诱导的含Pb碳酸盐沉淀在土壤中的稳定性更好,在Pb污染土壤修复方面有重要的应用价值。

Efficacy of Combined Phacoemulsification and Goniosynechialysis in the Treatment of Patients with Primary Angle Closure Disease and Concomitant Cataract at Preah Ang Duong Hospital in Cambodia

引用

Open Journal of Ophthalmology 2024年第3期14卷 284-312页

作者： Channdarith Kith Piseth Kong Kossama Chukmol Bunseng Sea Seiha do Meng Ngy Amarin Mar Ratneary Hav Saly Saint Department of Ophthalmology Preah Ang Duong Hospital Phnom Penh Cambodia Department of Ophthalmology Khmer-Soviet Friendship Hospital Phnom Penh Cambodia Faculty of Medicine University of Health Sciences Phnom Penh Cambodia

Background: Goniosynechialysis is a surgical procedure that has been shown to slow the progression of glaucoma in oriental eyes with chronic angle closure glaucoma. This procedure was successful in 80% of cases, and the peripheral anterior syenchiae did not exist until one year later. Nonetheless, there is little evidence of its efficacy in our context. Our study aims to investigate the efficacy of goniosynechialysis during phacoemulsification in patients with primary angle closure disease and concomitant cataract. Methods: This was an observational, prospective study. The intra-ocular pressure, need for anti-glaucoma drugs, visual acuity, the extent of synechiae, anterior chamber depth, surgical success rate, and other indicators were monitored for at least three months following surgery. Results: This study included 114 patients (118 eyes), 61 with chronic angle closure glaucoma (51.69%), 33 with primary angle closure (27.97%), and 24 with acute attack angle closure (20.34%), who were surgically treated with phacoemulsification and goniosynechialysis (Phaco-GSL). The mean intra-ocular pressure had significantly decreased three months after surgery (pre- vs post-op: 22.04 ± 10.86 vs 15.41 ± 6.06 mmHg, p-value p-value p-value p-value p-value Conclusion: Regardless of the type of glaucoma, combined phacoemulsification-goniosynechialysis is effective in lowering pressure, restoring vision, reducing the need for anti-glaucoma drugs, and preventing the synechial recurrence. Success was higher in eyes with less extensive synechiae. Phaco-GSL is safe and effective in the treatment of primary angle closure diseases with co-existing cataract.

Sensors Applied to Plant Breeding: Leaf Reflectance Indices (LRIs) and Resistance to Anthracnose in Capsicum annuum L. var. annuum

引用

Advances in Remote Sensing 2024年第1期13卷 1-17页

作者： Rosimara Barboza Bispo Maria do Socorro Bezerra Araújo Antônio André da Silva Alencar Cláudia Pombo Sudré Rosana Rodrigues Plant Breeding Laboratory Darcy Ribeiro North Fluminense State University Campos dos Goytacazes Brazil Plant Breeding Laboratory University of the State of Mato Grosso Cáceres Brazil

The present work investigated the efficiency of leaf reflectance indices in the identification of Capsicum annuum L. var. annuum resistant to anthracnose in the fruit. Twenty-five F5:6 families originating from contrasting parents were assessed;the parents were accession UENF 2285 (susceptible to anthracnose) and accession UENF 1381, a hot pepper resistant to anthracnose in the fruit. The experiment was carried out in an experimental field in Campos dos Goytacazes, Rio de Janeiro, Brazil, between May and October of 2021. The treatments were arranged in a randomized block design, with three replications and five plants per plot. Fifteen LRIs were estimated using a CI-710 portable mini leaf spectrometer. The assessments covered all plant growth after flowering, and a total of six assessments were performed at 15-days intervals, beginning at 35 and ending 120 days after flowering (DAFs). Analysis of variance in a split-plot scheme was performed, as were tests of mean groupings and principal components analysis (PCA). The best period for evaluating leaf reflectance indices in C. annuum var. annuum is 120 days after flowering. The leaf reflectance indices PRI, CNDVI and Ctr2 stood out as effective in distinguishing between resistant and susceptible genotypes.
