IntroductionWith urbanization and industrialization in the developing world, urban and peri-urban agriculture is increasingly contributing to urban food systems, employment, and income generation opportunities. However, urbanization and industrialization may release harmful pollutants, including heavy metals and trace elements into agricultural soils, posing ecological, environmental and public health concerns. This paper assessed the potential risks of soil contamination with heavy metals and trace elements in peri-urban farmlands in Nairobi city catchment in Kenya. MethodsA total of 60 soil samples were collected from ten vegetable farming zones (S1-S10) and processed following standard protocols. The concentrations of As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, V and Zn were analyzed in the samples using inductively coupled plasma-mass spectrometry (ICP-MS). Results and discussionResults revealed that the soil samples have elevated concentrations of As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, V and Zn, with some elements including As (1.7%), Cd (13.3%), Mn (80%), Pb (1.7%) and Zn (11.7%) exceeding the permissible thresholds for agricultural soils. The spatial distribution of the elements exhibited three similar distribution patterns with slight variations between the hotspot sites of the different elements: (i) Co and Mn, (ii) Cu and Cr and (iii) As, Cd, Fe, Hg, Pb and Zn, while Ni and V exhibited singular spatial distributions compared to other elements. Elements such as As, Cd, Co, Fe, Hg, Mn, Pb and Zn appeared to be of anthropogenic enrichment, while Cr, Cu, Ni and V appeared to originate mainly from lithogenic and natural sources. The elements As, Cd, Hg and Pb exhibited high ecological risks, with Cd contributing about 46-66% of the overall ecological risk. The sampling sites S1, S5, S7, S9 and S10 depicted the highest ecological risks of 145, 103, 146, 121 and 146, respectively. The findings call for proper zoning of suitable agricultural areas and sound waste management protocols in urban and peri-urban landscapes. Further, remediation of contaminated soils and farmers’ sensitization are recommended for ecological and public health risk alleviation.

Objectives: Air pollution health risk assessments (AP-HRAs) provide a method to quantify health effects for entire populations. In Switzerland, AP-HRAs are included in Swiss assessments for Transport Externalities (STEs), ordered by public authorities since the 1990s. This study aimed to describe the differences among national and international AP-HRAs for Switzerland.Methods: We compared input data, approaches and results across AP-HRAs over time. Results and input data for each AP-HRA were expressed as a ratio compared to the most recent STE (in most cases STE-2010).Results: Substantial variation across AP-HRAs was found. For all-cause adult mortality attributed to particulate matter (the most frequent outcome-pollutant pair), the ratio in HRAs oscillated from 0.40 to 2.09 (times the STE-2010 value). Regarding input data, the ratio ranged from 0.69 to 1.26 for population exposure, from 0 to 1.81 for counterfactual scenario, from 0.96 to 1.13 for concentration-response function and from 1.03 to 1.13 for baseline health data.Conclusion: This study demonstrates that methods matter for AP-HRAs. Transparent and possibly standardized reporting of key input data and assumptions should be promoted to facilitate comparison of AP-HRAs.

Hyperlipidemia results in endothelial dysfunction, which is intimately associated with disturbed mitochondrial homeostasis, and is a real risk factor for cardiovascular diseases (CVDs). Triphenylphosphonium (TPP+)-HT, constructed by linking a mitochondrial-targeting moiety TPP+ to hydroxytyrosol (HT), enters the cell and accumulates in mitochondria and is thus an important candidate drug for preventing hyperlipidemia-induced endothelial injury. In the present study, we found that TPP-HT has a better anti-inflammatory effect than HT. In vivo, TPP-HT significantly prevented hyperlipidemia-induced adverse changes in the serological lipid panel, as well as endothelial and mitochondrial dysfunction of the thoracic aorta. Similarly, in vitro, TPP-HT exhibited similar protective effects in palmitate (PA)-induced endothelial dysfunction, particularly enhanced expression of the mitochondrial ETC complex II, recovered FoxO1 expression in PA-injured human aorta endothelial cells (HAECs) and promoted FoxO1 nuclear translocation. We further demonstrated that FoxO1 plays a pivotal role in regulating ATP production in the presence of TPP-HT by using the siFoxO1 knockdown technique. Simultaneously, TPP-HT enhanced Nrf2 nuclear translocation, consistent with the in vivo findings of immunofluorescence, and the antioxidant effect of TPP-HT was almost entirely blocked by siNrf2. Concomitantly, TPP-HT’s anti-inflammatory effects in the current study were primarily mediated via the p38 MAPK/NF-κB signaling pathway in addition to the FoxO1 and Nrf2 pathways. In brief, our findings suggest that mitochondria-targeted TPP-HT prevents lipotoxicity induced endothelial dysfunction by enhancing mitochondrial function and redox balance by promoting FoxO1 and Nrf2 nuclear translocation.

In this paper, by using Jensen–Mercer’s inequality we obtain Hermite–Hadamard–Mercer’s type inequalities for a convex function employing left-sided (k, ψ)-proportional fractional integral operators involving continuous strictly increasing function. Our findings are a generalization of some results that existed in the literature.
Aircraft Noise Reduction Strategies and Analysis of the Effects
Authors: Xie Jinlong , Zhu Lei , Lee Hsiao Mun 
Published: January 2023

In this study, six aircraft noise reduction strategies including the optimization of aircraft type, regulation of night flight number, optimization of flight procedure, modification of operating runway, land use planning and installation of sound insulation windows were proposed to alleviate the harmful impact of aircraft noise on the local area and population near Guangzhou Baiyun International Airport (BIA) in China. The effects of all proposed strategies except for land use planning and sound insulation windows were simulated and analyzed using CadnaA software. The results indicate that these noise reduction strategies have their own advantages and each of them can serve as an effective noise reduction measure for different applications. For instance, the replacement of noisy aircraft with low-noise aircraft can simultaneously reduce the area and population exposed to a high noise level, while the optimization of flight procedure can only reduce the population exposed under relatively low noise levels (70 ≤LWECPN ≤ 75 dB). Nevertheless, the modification of operating runway is more effective in reducing the population suffering under high noise levels (LWECPN > 85 dB). Among these strategies, reducing the number of night flights is found to be most effective in reducing the overall noise-exposed area and population. Additionally, with the assistance of noise mapping, proper land use planning was suggested according to national standards, and the installation of sound insulation windows with different sound reduction grades can be determined for different areas impacted by the aircraft noise of BIA. It is believed that the results of this study can be applied as a reference in selecting suitable noise reduction strategies to improve the acoustic environment of a specific airport.

Relapsing fever (RF) is an arthropod-borne disease caused by Borrelia spirochete, which is one of the major public health concerns in endemic regions including Africa. However, information on Borrelia spirochetes is limited in Zambia. Here, we investigate the Borrelia spirochetes harbored by Ornithodoros ticks in Zambian National Parks. We analyzed 182 DNA samples pooled from 886 Ornithodoros ticks. Of these, 43 tested positive, and their sequence revealed that the ticks harbored both Old and New World RF borreliae. This research presents the first evidence of Old-World RF borreliae in Zambia. The New World RF borreliae detected herein differed from the Candidatus Borrelia fainii previously reported in Zambia and were closely related to the pathogenic Borrelia sp. VS4 identified in Tanzania. Additionally, Borrelia theileri was recently reported in Zambia. Hence, at least four different Borrelia species occur in Zambia, and the organisms causing relapsing fever there might be more complex than previously thought. We empirically confirmed that real-time PCR with TaqMan minor groove binder probes accurately and simultaneously detected both Old and New World RF. In this manner, they could facilitate quantitative analyses of both types of RF borreliae. Subsequent investigations should endeavor to isolate the aforementioned Borrelia spp. and perform serosurveys on patients with RF.
Transformations de l'industrie espagnole dans le cadre de la modernisation : clés d'interprétation
Authors: Méndez Ricardo , Mecha Rosa 
Published: January 2023

Transformations in spanish industry within the globalisation framework : some aids to interpretation.
After the political and economic transition of 1975, the undeniable dynamism of Spanish industry must be situated in a phase of breaking with the structural characteristics of the preceding years. The effects of this mutation are speeding up the internal differentiation of the industrial structures. It is putting into the foreground the electronics and computer branches and is permanently affecting traditional industries. The expansion of specialised small and medium-sized firms ranks with an intensive concentration of business volume and of power enjoyed by a few large firms. These evolutions make up a new industrial geography which is characterised by (a) the decline of regions with a long industrial tradition and the transfer of intensive work activities towards the inner regions with lower production costs and easy access, by
(b) the disappearance of isolated units and their replacement by concentrations of firms along communications routes and by
(c) the increase of the considerable weight of the Madrid and Barcelona metropolitan areas. The unequal ability of areas to offer competitive advantages has become the essential factor in spacial differentiation.

Historical flooding in the Ter basin (Catalonia). History, heritage and territorial development.
This article aims at taking a positive view of historical flooding and the marks this has left on the territory as a strategy for territorial development, using the River Ter basin (Catalonia) as an example. It first presents the policy of patrimonialisation of the floods in the Alba-Ter Consortium and the main distinctive features in the studied area, and provides a brief review of the great floods which took place in history. It then sets out, classifies and describes the principal witnesses to the flooding which took place in this Mediterranean river basin. Finally, it looks in more depth at the value, from a heritage and tourism point of view, of some of the most interesting witnesses, such as flood markers, alterations made to certain buildings to deal with the flood risk, natural spaces liable to flooding and hydraulic defence projects.

PHILOSOPHICAL CONNOTATIONS OF THE HUMAN VOLITIONAL PRINCIPLE
Authors: Т. А. Бондаренко, , С. Н. Яременко, 
Published: January 2023

Выясняется генезис понятия воли, что приобретает особый смысл, теоретическую и практическую значимость в современных условиях. Производится экспликация дискурса о волевом начале от античности до современности. В классическом понимании воля заключается в способности разума к самоопределению, а также означает фундаментальное свойство сущего, предшествующее всей природе и разуму. На фоне непротивопоставления воли разуму она трактуется как специфическая причинность и отличается от чисто интеллектуальной сферы. Ретроспектива рассматриваемой проблемы включает анализ позиций таких философов, как Аристотель, Августин Блаженный, И. Кант, Ф. Ницше, А. Шопенгауэр, А. Бергсон, А. Швейцер и др. Отмечены новации в осмыслении феномена воли в связи с новейшими научными открытиями в области естественных наук и психологии.
The genesis of the concept of will is revealed, which acquires a special meaning, theoretical and practical significance in modern conditions. Explication of the discourse about the volitional principle from antiquity to the present is made. In the classical understanding, the will consists in the ability of the mind to self- determination, and also means a fundamental property of existence that precedes all nature and reason. Against the background of non-opposition of will to mind, it is interpreted as a specific causality and differs from the purely intellectual sphere. The retrospective of the problem under consideration includes an analysis of the positions of such philosophers as Aristotle, Augustine the Blessed, I. Kant, F. Nietzsche,A. Schopenhauer, A. Bergson, A. Schweitzer, etc. Innovations in understanding the phenomenon of will in connection with the latest scientific discoveries in the field of natural sciences and psychology are noted.
