Authors: Siti Nida Saripah  , Fathoni Mahardika  , Deris Santika
Published: August 2024

In improving the school financial administration system, the author developed a website-based school payment application at the early childhood education level. This application makes it easier for school treasurers to manage school financial administration and reduces the risk of data loss or human error in recording payments. The school payment application is implemented in one of the Early Childhood Education areas in Rancakalong sub-district, namely PAUD Sejahtera. However, the success of implementing a school payment application does not solely depend on its technical functionality alone. Psychological, social, and organizational factors also play an important role in accepting and using these technologies. Therefore, evaluating user readiness in accepting and adopting school payment applications is important to understand. The method used in this research is the Technology Readiness Index. This method uses four variables, namely optimism, innovativeness, discomfort and insecurity. The respondents for this research consisted of school treasurers and parents, with a TRI score of 0.335 which was categorized in the medium technology readiness index, thus PAUD Sejahtera was ready to use the school payment application by paying attention to aspects of inconvenience and insecurity which still received low scores of 0.786 and 1.13.

The Effect of Transformational Leadership Style on Organizational Performance: Case of Moroccan Judo Associations
Authors: HANNOUN Omar
Published: August 2024

Transformational leadership has gained significant scholarly attention for its potential to impact organizational performance. This study looked at the function of transformational leadership and its elements, which include intellectual stimulation, idealized influence, inspirational motivation, and individual consideration, in 20 Judo associations in Morocco. Out of 200 surveys distributed, a multiple regression analysis with a significance threshold of p < 0.05 could be performed on 158 of them. Findings indicate that transformational leadership, along with idealized influence and individual consideration, significantly and positively affect organizational performance. However, inspirational motivation and intellectual stimulation do not have a significant impact. It implies that in order to improve organizational performance, leaders should concentrate on idealized influence and individual consideration.
Destiny During Repression. Case Study: Nicolae Rădulescu
Authors: CIORNEA Andrei
Published: August 2024

The article discusses the case of the student Nicolae Rădulescu, one of the five young people who were included in the Burning Bush (Rugul Aprins) group and arrested in 1958 and seeks to reconstruct the facts by gathering the data from the documents of the former Secret Police and the testimony of the victim, the only current survivor of the group. The reading of the interrogation minutes and the numerous informative notes that can be found in the files drawn up in his name from the Informative and Criminal Fund, constitutes, from a witness' perspective, eloquent evidence of the tragedy of the situation, of the mystification and distortion of reality, of the fabrication of a profile in line with the purposes of the Secret Police. Thus, the analysis of the documents in the CNSAS Archive related to the arrest, investigation and trial provides an idea of the specific mechanisms of an oppressive regime in its struggle to annihilate any form of opposition or resistance. The efforts of student Nicolae Rădulescu to preserve dignity will inevitably bring to our attention the concept of the value of the human being in the context of a totalitarian regime. Another direction of the present article is the pursuit of the legitimacy of the fight waged by Nicolae Rădulescu in the name of preserving the Christian identity in a state that guaranteed religious freedom through the Constitution.

A psoríase é uma doença inflamatória crônica, caracterizada pela aceleração da renovação dos queratinócitos, resultando em lesões cutâneas eritematosas e escamosas. A fisiopatologia da psoríase envolve a ativação anômala das células T, levando à amplificação da resposta inflamatória. A prevalência da psoríase varia de 2% a 3% da população global, afetando principalmente indivíduos de ascendência europeia. A doença é poligênica, com fatores desencadeadores ambientais, como infecções e estresse, desempenhando papel importante. O manejo da psoríase inclui tratamentos tópicos e sistêmicos, mas as terapias biológicas surgem como uma abordagem mais eficaz e segura, com inibidores de citocinas como TNF-α, IL-17 e IL-23 mostrando alta eficácia. Embora as terapias biológicas sejam promissoras, desafios como custo e necessidade de monitoramento a longo prazo permanecem. A revisão integrativa analisou 10 estudos e confirmou a eficácia superior das terapias biológicas em comparação com tratamentos tradicionais, especialmente na melhora da qualidade de vida dos pacientes, apesar de riscos associados à imunossupressão. A personalização do tratamento e a combinação com outras terapias são estratégias promissoras para otimizar os resultados clínicos, destacando a necessidade de intervenções terapêuticas precoces e contínuas.

(Éco)tourisme en Haïti : le cas
du mégaprojet Destination Île à Vache
Authors: Osna Walner
Published: August 2024

Cet article analyse le mégaprojet touristique « Destination Île à
Vache » qui se prétend (éco)touristique. Nous soutenons que la mise en œuvre à
Île à Vache (Haïti) de ce mégaprojet est plutôt contradictoire aux fondements
théoriques de l’écotourisme et s’inscrit dans une dynamique de dépossession et
d’accaparement de terres. À partir d’une enquête de terrain qualitative menée à
l’Île à Vache entre décembre 2019 et janvier 2020, notre argumentation confronte
trois grandes caractéristiques de l’écotourisme avec l’exécution du projet.
D’abord, les résultats de cette recherche montrent que la population locale est
exclue du projet. Ensuite, les conséquences socio-environnementales du projet
sont contraires à son fondement (éco)touristique, car son exécution représentait
plutôt une menace pour l’environnement. Finalement, nous avons découvert qu’il a
fragilisé les conditions socioéconomiques des paysan·nes sur l’île au lieu
d’apporter des améliorations. Nous concluons donc que Destination Île à Vache en tant que mégaprojet touristique
illustre la thèse selon laquelle les mégaprojets provoquent dépossession,
déplacement et appauvrissement des populations concernées.
Le rôle des organismes transnationaux
dans la transformation de la ville. Marseille, d’une ville industrielle à la métropole
créative
Authors: Martin-Colonna Cyril , Kadri Boualem
Published: August 2024

La crise industrielle occidentale des années 1970-1980 a induit
la remise en question du modèle économique de développement urbain. Ce dernier
sera alors conçu à travers la culture, les arts, le tourisme et l’événementiel.
Le concept de « ville créative », connu d’abord en Amérique du Nord, est repris
par l’Union européenne. Cette organisation transnationale a proposé aux villes,
dès 1985, un programme nommé « Capitales européennes de la culture », dans le
but de redynamiser l’espace urbain par le modèle de la ville créative. Au-delà
du programme culturel, être Capitale européenne de la culture est synonyme de
transformations urbaine, économique et sociale. Quel rôle exerce alors l’acteur
transnational dans le développement de la ville européenne et le gouvernement
local ? Comment les acteurs du développement urbain s’adaptent-ils à ce rôle
d’influence ? L’observation sera effectuée à partir du cas de Marseille, une
ville industrielle en transition vers le modèle de métropole culturelle, et
l’analyse s’appuiera sur la théorie sociologique néo-institutionnelle.

Constantine est une ville de l’Est algérien, vieille de plus de
trois mille ans. Elle regorge d’atouts touristiques qui ont fait sa notoriété et
sa distinction depuis plusieurs civilisations déjà. Sa vieille ville est un
point d’attraction touristique des plus prégnants. Visiter ses rues permet de
naviguer à travers l’histoire, la culture et les arts d’une cité plusieurs fois
millénaire. Le présent article analyse les parcours touristiques anciens à
Constantine suivant deux méthodes : quantitative, en ayant recours à la space syntax ; et qualitative, à travers la recherche
historique et l’observation. Cela aide à comprendre la logique de déplacement
des touristes à l’intérieur du tissu ancien et à déceler, dans la configuration
actuelle, les chemins les plus fréquentés ainsi que les parcours les plus
anciens et les mieux nantis en monuments et lieux historiques. L’étude a révélé
que, contrairement à ce que la configuration spatiale actuelle fait penser, les
parcours précoloniaux sont les plus intéressants à visiter du fait qu’ils sont
les mieux pourvus en monuments et lieux historiques.
Les visées expressives des parents choisissant une scolarité alternative pour leurs enfants
Authors: Proboeuf Pauline , Legavre Amélia
Published: August 2024

Les parents optant pour des scolarités alternatives (écoles aux pédagogies alternatives et instruction en famille) mettent en avant des visées « expressives », ciblant une prise en compte par les adultes de ce qu’exprime l’enfant dans le cadre de son éducation (besoins, intérêts, gouts, etc.). Toutefois, ces parents témoignent d’attentes pouvant varier. Cet article s’attache à définir et à détailler les différents types de visées qui peuvent se situer derrière une même attention portée aux expressions de l’enfant. À partir de l’analyse d’un corpus de 95 entretiens avec des parents ayant choisi une scolarité alternative et de l’observation d’évènements dédiés à ce type de scolarités, nous avons pu distinguer trois variations de visées expressives : les visées d’émancipation, les visées de protection et les visées de distinction.
Research on marine flexible biological target detection based on improved YOLOv8 algorithm
Authors: Tian Yu , Liu Yanwen , Lin Baohang , Li Peng
Published: August 2024

To address the challenge of suboptimal object detection outcomes stemming from the deformability of marine flexible biological entities, this study introduces an algorithm tailored for detecting marine flexible biological targets. Initially, we compiled a dataset comprising marine flexible biological subjects and developed a Contrast Limited Adaptive Histogram Equalization (CLAHE) algorithm, supplemented with a boundary detection enhancement module, to refine underwater image quality and accentuate the distinction between the images’ foregrounds and backgrounds. This enhancement mitigates the issue of foreground-background similarity encountered in detecting marine flexible biological entities. Moreover, the proposed adaptation incorporates a Deformable Convolutional Network (DCN) network module in lieu of the C2f module within the YOLOv8n algorithm framework, thereby augmenting the model’s proficiency in capturing geometric transformations and concentrating on pivotal areas. The Neck network module is enhanced with the RepBi-PAN architecture, bolstering its capability to amalgamate and emphasize essential characteristics of flexible biological targets. To advance the model’s feature information processing efficiency, we integrated the SimAM attention mechanism. Finally, to diminish the adverse effects of inferior-quality labels within the dataset, we advocate the use of WIoU (Wise-IoU) as a bounding box loss function, which serves to refine the anchor boxes’ quality assessment. Simulation experiments show that, in comparison to the conventional YOLOv8n algorithm, our method markedly elevates the precision of marine flexible biological target detection.
Inter-subspecies diversity of maize to drought stress with physio-biochemical, enzymatic and molecular responses
Authors: Eskikoy Gokhan , Kutlu Imren
Published: August 2024

Background

Drought is the most significant factor limiting maize production, given that maize is a crop with a high water demand. Therefore, studies investigating the mechanisms underlying the drought tolerance of maize are of great importance. There are no studies comparing drought tolerance among economically important subspecies of maize. This study aimed to reveal the differences between the physio-biochemical, enzymatic, and molecular mechanisms of drought tolerance in dent (Zea mays indentata), popcorn (Zea mays everta), and sugar (Zea mays saccharata) maize under control (no-stress), moderate, and severe drought stress.

Methods

Three distinct irrigation regimes were employed to assess the impact of varying levels of drought stress on maize plants at the V14 growth stage. These included normal irrigation (80% field capacity), moderate drought (50% field capacity), and severe drought (30% field capacity). All plants were grown under controlled conditions. The following parameters were analyzed: leaf relative water content (RWC), loss of turgidity (LOT), proline (PRO) and soluble protein (SPR) contents, membrane durability index (MDI), malondialdehyde (MDA), and hydrogen peroxide (H2O2) content, the antioxidant enzyme activities of superoxide dismutase (SOD), ascorbate peroxidase (APX), and catalase (CAT). Additionally, the expression of heat shock proteins (HSPs) was examined at the transcriptional and translational levels.

Results

The effects of severe drought were more pronounced in sugar maize, which had a relatively high loss of RWC and turgor, membrane damage, enzyme activities, and HSP90 gene expression. Dent maize, which is capable of maintaining its RWC and turgor in both moderate and severe droughts, and employs its defense mechanism effectively by maintaining antioxidant enzyme activities at a certain level despite less MDA and H2O2 accumulation, exhibited relatively high drought tolerance. Despite the high levels of MDA and H2O2 in popcorn maize, the up-regulation of antioxidant enzyme activities and HSP70 gene and protein expression indicated that the drought coping mechanism is activated. In particular, the positive correlation of HSP70 with PRO and HSP90 with enzyme activities is a significant result for studies examining the relationships between HSPs and other stress response systems. The discrepancies between the transcriptional and translational findings provide an opportunity for more comprehensive investigations into the role of HSPs in stress conditions.

Published: August 2024

Los procesos de digitalización han modificado sustancialmente los modos de producción y consumo de bienes y servicios en la sociedad, así como las diferentes interacciones de las que somos parte. Los estados y sus intervenciones no han quedado por fuera de estos procesos. La situación de pandemia sanitaria por covid-19 -aunque ya se venía gestando previamente-, ha acelerado el uso de las Tecnologías de la Información y la Comunicación (TIC’s) en la gestión e implementación de políticas públicas en general y sociales en particular. En este marco, el objetivo de este escrito es comparar algunas políticas de transferencias de ingresos o garantía de ingresos, emergentes en el contexto de pandemia sanitaria por covid-19 en el estado argentino y español. A partir de etnografías virtuales en grupos de personas receptoras de la red social Facebook, se toman como casos de análisis el Ingreso Familiar de Emergencia y el Refuerzo Alimentario en el caso argentino y del Ingreso Mínimo Vital en España. Se ha buscado explorar algunas dimensiones del proceso de implementación de programas cuya gestión se realizó de manera virtual: Dudas, expresiones en torno al proceso de inscripción y miradas sobre la prestación, en pos de comprender las dificultades a las que se enfrenta la población potencialmente receptora de estas políticas. Los resultados obtenidos pretenden demostrar las potencialidades y limitaciones que ofrecen los procesos de digitalización en las políticas de lucha contra la pobreza y la exclusión social.

Authors: G Vineetha. , Pradeep M. , Harathi P.N , Rajasekharam T.
Published: August 2024

Bacterial leaf blight is one of the most destructive diseases in rice which leads to yield loss of 20-40%. This study aimed to assess the prevalence of bacterial leaf blight in rice across Andhra Pradesh. A roving survey was conducted during Kharif 2023 in Andhra Pradesh to assess the severity of bacterial leaf blight disease in rice. The percent disease index averages from 25 to 59.6% was recorded. The maximum disease severity was observed in the tillering stage. The maximum percent disease index was observed in Chinta reddy Palem village in Nellore district (59.60%), while the minimum was recorded in Denduluru village in Eluru district (25%). The disease was more severe in the BPT-5204 variety. In spite chemical control, there are chances of development of resistance. There is a need for nanotechnology intervention for management of disease. This study also investigates the antimicrobial activity of copper and silver nanoparticles against Xoo by using paper disc diffusion method under invitro conditions. Silver nanoparticles exhibited the highest anti-microbial activity when compared with copper nanoparticles at 0.1% and 0.2% concentrations, respectively. Further research is needed to explore the field application of nanoparticles and their long-term effects on rice crops.

Published: August 2024

A field experiment was conducted during rabi 2022-23 to study the effect of Integrated Nutrient Management on physical and chemical properties of soil such as soil bulk density, maximum water holding capacity, pH, electrical conductivity, organic carbon, available major nutrients. The following parameters were investigated in an experiment comprising eleven treatments replicated thrice in randomized complete block design with quinoa. The results of the experiment suggested that soil physico-chemical properties like maximum water holding capacity, organic carbon had significantly influenced with the application of 50% nitrogen dose (ND) + 50% N through FYM + seed treatment (Azotobacter + PSB). Soil major nutrients like nitrogen, phosphorus and potassium had a higher significant effect with the application of 50% nitrogen dose (ND) + 50% N through vermicompost (VC) + seed treatment (Azotobacter + PSB) in comparison to application of 100% fertilizer dose. In the other hand, soil properties like bulk density, pH, electrical conductivity did not have a significant influence with the practice of Integrated Nutrient Management in quinoa.

Genetic Variability, Correlation and Path Analysis of Yield and its Attributing Traits in Rice (Oryza sativa L.)
Authors: Babu Hani , N Thouseem
Published: August 2024

Genetic variability in a species is a crucial aspect that determines its adaptability, resilience and potentiality for improvement. The present study was aimed to estimate variability, correlation and path coefficients of fifteen rice accessions from Kerala Agricultural University for grain yield and its attributing traits. PCV was found to be higher than GCV for all the characters studied. High PCV and GCV values were recorded for the traits like flag leaf length, leaf area, number of filled grains per panicle, fertility percentage and single plant yield indicating that direct selection can be employed for the improvement of these traits. High heritability coupled with high genetic advance was shown by the traits plant height, flag leaf length, flag leaf width, leaf area, number of filled grains per panicle, total grains per panicle and single plant yield. Hence direct selection will be highly effective for improvement of these traits. Single plant yield showed significant positive correlation with days to 50% flowering, number of filled grains per panicle, total number of grains per panicle and harvest index at phenotypic level and with harvest index at genotypic level. Path analysis has ascertained that there exist direct and indirect effects for all the independent traits studied. Positive direct effects on single plant yield at genotypic level was shown by the traits number of panicles, panicle length, 1000 grain weight, leaf area, grain length, kernel breadth and harvest index. The characters like days to 50% flowering, plant height, number of tillers, flag leaf length, flag leaf width, total number of grains per panicle, 1000 grain weight, kernel length, kernel breadth and L/B ratio had significant positive direct effects at phenotypic level. The results have shown that the accessions studied can be used for further selection for crop improvement programmes. The interactions between the contributing traits are so complex that a balanced method of selection is to be practised for their improvement.
Effect of Water Conservation Technologies on Water use Efficiency of Pearl Millet Green Gram Intercropping System in Semi-Arid Kenya
Authors: Stephen Karanja K. , Josiah Kinama M. , Juliana Cheboi J.
Published: August 2024

The insufficient and inadequate soil moisture content in Kenyan’s arid areas has steadily reduced crop production. A field experiment was conducted during 2022/2023 short rain season to evaluate the effect of water conservation technologies and cropping systems on soil moisture dynamics and water use efficiency of selected pearl millet and green gram varieties planted in sole and intercrop system in Kambi-Mawe and Katumani research stations. The experiment was arranged in a split-plot design with individual treatments arranged in a randomized complete block design, replicated three times. The main plots comprised of water conservation technologies (ngolo pits, contour furrows) taking conventional tillage as a control. The cropping system included sole cropping of pearl millet (PMI, PM3), sole green gram varieties (N26 and Biashara) and their intercrops. Soil samples were collected at the depth of 0-20, 20-40 and 40-60 cm at 30 days, 45 days and 60 days after crop emergence and transported to laboratory for fresh weight determination. They were oven-dried at 105oC for 48 hours and the dry weight recorded. Water use efficiency (WUE) was calculated using seasonal crop evapotranspiration (ET) and crop yield. Collected data was analysed using GenStat statistical software 15th edition while mean separation was done using Tukey HSD at p ≤ 0.05 significance level. Results illustrated that water conservation technologies and cropping system significantly increased the soil moisture content recorded at different sampling times. Generally, significantly higher soil moisture was recorded in ngolo pits, followed by contour furrows, while conventional tillage recorded relatively lower soil moisture. Plots under intercropping systems recorded lower soil moisture compared to those under sole cropping irrespective of the crops. Higher WUE values were recorded in ngolo pits, and conventional tillage recorded the lowest values.

Introduction: Sickle cell disease (SCD) poses significant health challenges, particularly in regions like sub-Saharan Africa where its prevalence is high. Malaria, a prevalent infectious disease in this region, exacerbates the complications associated with SCD. Understanding the epidemiology and risk factors of malaria among SCD patients is crucial for effective management and control strategies.
Aim: To evaluate the prevalence and risk factors associated with malaria transmission among sickle cell anaemia patients in urban communities of Taraba State, Northeastern Nigeria.
Methods: The study involved the screening of sickle cell anaemia patients in selected health facilities in Taraba State from December 2022 to December 2023. Data on demographic characteristics, risk factors, and malaria status were collected using structured questionnaires and blood samples. Parasitological examination was conducted to determine malaria prevalence, and statistical analysis was performed using SPSS version 25.0.
Results: The study revealed a malaria prevalence of 12.9% among sickle cell anaemia patients, with higher rates observed in Takum compared to other communities. Malaria infection was more common among males, children aged 1-10 years, non-educated individuals, and those engaged in specific occupations like farming and trading. Risk factors such as stagnant water around residences, presence of bushes, lack of insecticidal nets, and use of indigenous herbs were associated with higher malaria transmission rates.
Conclusion: The findings underscore the importance of targeted interventions to mitigate malaria burden among sickle cell anaemia patients, including educational campaigns, access to preventive measures such as insecticidal nets, and improvement in environmental hygiene practices. Implementing these strategies is crucial for reducing malaria-related morbidity and mortality in affected communities.

The present investigation was undertaken to assess Standardization of different doses and durations of electric and magnetic field seed treatment on growth, yield and yield attributing traits of Bottle gourd (Lagenaria siceraria L.) The experiment was conducted during Rabi season 2022-23 at the field experimental centre, Department of Genetics and Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences (SHUATS), Prayagraj (U.P.). Seeds of Bottle gourd when treated with electric and magnetic fields with various doses and frequencies/durations, treatment T₆ Magnetic field (250mT) for 20 minutes performed best in all growth and yield attributing traits when compared to other treatments. This study is helpful in good crop establishment and prevent the seed from pest and diseases, it also promotes good yield and as it is chemically free and causes no harm to soil it will also benefit farmers. It is highly cost-effective since once the initial research is done, the process can be easily replicated and scaled.

We present a three‐dimensional P and S wave tomography model beneath the central Japan Sea using arrival time data obtained by long‐term ocean bottom seismometer observations. The tomographic model is determined down to over 300 km. The resulting tomographic image has two features in the mantle wedge. First, a remarkable low‐velocity region is spread within the shallow part of the mantle wedge beneath the Japan arc with a slight extension beneath the Japan Sea. Second, an inclined low‐velocity anomaly exists in the deeper part beneath the Japan Sea and converges to the slab at ~300 km depth. Moreover, its anomaly amplitude is distinctly small compared to the shallow part of the low‐velocity region. These low‐velocity anomalies are interpreted to represent fluids that were dehydrated from the Pacific and Philippine Sea slabs and melt production affected by the fluid. Our observations suggest that the deep dehydration from the Pacific slab is found at a depth of approximately 300 km and large‐scale upwelling flow mechanically induced by plate subduction exists beneath the Japan Sea. Our results indicate the importance of the deep heterogeneous mantle wedge structure beneath the Japan Sea with regards to better understanding the magmatism of the subduction dynamics in Japan and the evolution of the opening of the Japan Sea.
Space‐time ambiguity functions for electronically scanned ISR applications

Published: April 2015

Electronically steerable array (ESA) technology has recently been applied to incoherent scatter radar (ISR) systems. These arrays allow for pulse‐to‐pulse steering of the antenna beam to collect data in a three‐dimensional region. This is in direct contrast to dish‐based antennas, where ISR acquisition is limited at any one time to observations in a two‐dimensional slice. This new paradigm allows for more flexibility in the measurement of ionospheric plasma parameters. Multiple ESA‐based ISR systems operate currently in the high‐latitude region where the ionosphere is highly variable in both space and time. Because of the highly dynamic nature of the ionosphere in this region, it is important to differentiate between measurement‐induced artifacts and the true behavior of the plasma. Often, three‐dimensional ISR data produced by ESA systems are fitted in a spherical coordinate space and then the parameters are interpolated to a Cartesian grid, potentially introducing error and impacting the reconstructions of the plasma parameters. To take advantage of the new flexibility inherent in ESA systems, we present a new way of analyzing ISR observations through use of the space‐time ambiguity function. The use of this new measurement ambiguity function allows us to pose the ISR observational problem in terms of a linear inverse problem whose goal is the estimate of the time domain lags of the intrinsic plasma autocorrelation function used for parameter fitting. The framework allows us to explore the impact of nonuniformity in plasma parameters in both time and space. We discuss examples of possible artifacts in high‐latitude situations and discuss possible ways of reducing them and improving the quality of data products from electronically steerable ISRs.

In situ measurements were made to determine oxygen (O2) metabolic balance in the upper oligotrophic ocean from diel changes in O2 to argon (Ar) ratios. The study took place during 13–24 March 2014, at the Hawaii Ocean Time‐series Station ALOHA (A Long‐term Oligotrophic Habitat Assessment), in the North Pacific Subtropical Gyre. Microbial community respiration and gross O2 production, estimated from in situ diel changes in O2/Ar saturation, agreed well with those calculated using other independent methods. Net oxygen production (NOP), estimated from in situ diel changes in O2/Ar saturation, showed large day‐to‐day variability. However, when averaged over the entire observational period, mean diel NOP was in relatively good agreement with the estimated mean steady state NOP (9.2 ± 9.3 mmol O2 m−2 d−1 compared to 11.7 ± 1.1 mmol O2 m−2 d−1, respectively).

Measurements of the diurnal cycle of potassium (K) atoms between 80 and 110 km have been made during October (for the years 2004–2011) using a Doppler lidar at Kühlungsborn, Germany (54.1°N, 11.7°E). A pronounced diurnal variation is observed in the K number density, which is explored by using a detailed description of the neutral and ionized chemistry of K in a three‐dimensional chemistry climate model. The model captures both the amplitude and phase of the diurnal and semidiurnal variability of the layer, although the peak diurnal amplitude around 90 km is overestimated. The model shows that the total potassium density (≈ K + K+ + KHCO3) exhibits little diurnal variation at each altitude, and the diurnal variations are largely driven by photochemical conversion between these reservoir species. In contrast, tidally driven vertical transport has a small effect at this midlatitude location, and diurnal fluctuations in temperature are of little significance because they are small and the chemistry of K is relatively temperature independent.
