Published: February 2022

Abstract. Accurate measurements of ice hydrometeors are required to improve the
representation of clouds and precipitation in weather and climate models. In this study, a newly developed, synergistic retrieval algorithm that combines radar with passive millimeter and sub-millimeter observations is applied to observations of three frontally generated, mid-latitude cloud systems in order to validate the retrieval and assess its capabilities to constrain the properties of ice hydrometeors. To account for uncertainty in the assumed shapes of ice particles, the retrieval is run multiple times while the shape is varied. Good agreement with in situ measurements of ice water content and particle concentrations for particle maximum diameters larger than 200 µm is found for one of the flights for the large plate aggregate and the six-bullet rosette shapes. The variational retrieval fits the observations well, although small systematic deviations are observed for some of the sub-millimeter channels pointing towards issues with the sensor calibration or the modeling of gas absorption. For one of the flights the quality of the fit to the observations exhibits a weak dependency on the assumed ice particle shape, indicating that the employed combination of observations may provide limited information on the shape of ice particles in the observed clouds. Compared to a radar-only retrieval, the results show an improved sensitivity of the synergistic retrieval to the microphysical properties of ice hydrometeors at the base of the cloud. Our findings indicate that the synergy between active and passive microwave
observations may improve remote-sensing measurements of ice hydrometeors and thus help to reduce uncertainties that affect currently available data
products. Due to the increased sensitivity to their microphysical properties, the retrieval may also be a valuable tool to study ice hydrometeors in field campaigns. The good fits obtained to the observations increase confidence in the modeling of clouds in the Atmospheric Radiative Transfer Simulator and the corresponding single scattering database, which were used to implement the retrieval forward model. Our results demonstrate the suitability of these tools to produce realistic simulations for upcoming sub-millimeter sensors such as the Ice Cloud Image or the Arctic Weather Satellite.
A high-resolution monitoring approach of canopy urban heat island using a random forest model and multi-platform observations

Abstract. Due to rapid urbanization and intense human activities, the urban
heat island (UHI) effect has become a more concerning climatic and
environmental issue. A high-spatial-resolution canopy UHI monitoring method
would help better understand the urban thermal environment. Taking the city
of Nanjing in China as an example, we propose a method for evaluating canopy
UHI intensity (CUHII) at high resolution by using remote sensing data and
machine learning with a random forest (RF) model. Firstly, the observed
environmental parameters, e.g., surface albedo, land use/land cover,
impervious surface, and anthropogenic heat flux (AHF), around densely
distributed meteorological stations were extracted from satellite images.
These parameters were used as independent variables to construct an RF model
for predicting air temperature. The correlation coefficient between the
predicted and observed air temperature in the test set was 0.73, and the
average root-mean-square error was 0.72 ∘C. Then, the spatial
distribution of CUHII was evaluated at 30 m resolution based on the output
of the RF model. We found that wind speed was negatively correlated with
CUHII, and wind direction was strongly correlated with the CUHII offset
direction. The CUHII reduced with the distance to the city center, due to
the decreasing proportion of built-up areas and reduced AHF in the same
direction. The RF model framework developed for real-time monitoring and
assessment of high spatial and temporal resolution (30 m and 1 h) CUHII
provides scientific support for studying the changes and causes of CUHII,
as well as the spatial pattern of urban thermal environments.
Dynamical forcings in heavy precipitation events over Italy: lessons from the HyMeX SOP1 campaign
Authors: Miglietta Mario Marcello , Davolio Silvio
Published: February 2022

Abstract. The first Special Observation Period (SOP1) of HyMeX
(Hydrological cycle in the Mediterranean eXperiment) was held in fall 2012 and focused on heavy precipitation events (HPEs) and floods in the
northwestern Mediterranean. Nine intensive observation periods (IOPs)
involved three Italian target areas (northeastern Italy, NEI; Liguria and Tuscany, LT; central Italy, CI), enabling an unprecedented analysis of precipitation systems in these regions. In the present work, we highlight
the major findings emerging from the HyMeX campaign and in the subsequent
research activity over the three target areas by means of conceptual models and through the identification of the relevant recursive mesoscale features. For NEI, two categories of events (Upstream and Alpine HPEs) were
identified, which differ mainly in the temporal evolution of the stability
of the upstream environment and of the intensity of the impinging flow. The
numerical simulation of convection in the Po Valley was found to be very
sensitive to small changes in the environmental conditions, especially when
they are close to the threshold between “flow-over” and “flow-around” regimes. For LT, HyMeX SOP1 focused on orographically enhanced precipitation over the Apennines and quasi-stationary mesoscale convective systems over the sea or
close to the coast. For the latter category of events, associated with the
majority of the recent HPEs, local-scale or large-scale convergence lines
appear fundamental to trigger and sustain convection. These lines are
affected not only by the orography of the region, but also by the
perturbations induced by Sardinia and Corsica on the environmental flow,
and, at later times, by cold pools formed via evaporation of precipitation. For CI, a high low-level moisture content and marked low-level convergence
over the sea were critical to support deep convection in the IOPs affecting
the Tyrrhenian coast. For the HPEs affecting the Adriatic regions, a cut-off
low over the Tyrrhenian Sea induces intense bora over the Adriatic basin. Low-level convergence triggers convection over the sea, while orographic
uplift produces stratiform precipitation. The Adriatic Sea plays a critical
role mainly through air–sea exchanges, which modify the characteristics of the flow and in turn the effect of the orographic forcing.
Correction of field instabilities in biomolecular solid-state NMR by simultaneous acquisition of a frequency reference

Published: February 2022

Abstract. With the advent of faster magic-angle spinning (MAS) and
higher magnetic fields, the resolution of biomolecular solid-state nuclear
magnetic resonance (NMR) spectra has been continuously increasing. As a
direct consequence, the always narrower spectral lines, especially in
proton-detected spectroscopy, are also becoming more sensitive to temporal
instabilities of the magnetic field in the sample volume. Field drifts in
the order of tenths of parts per million occur after probe insertion or temperature
change, during cryogen refill, or are intrinsic to the superconducting
high-field magnets, particularly in the months after charging. As an alternative to a field–frequency lock based on deuterium solvent
resonance rarely available for solid-state NMR, we present a strategy to
compensate non-linear field drifts using simultaneous acquisition of a
frequency reference (SAFR). It is based on the acquisition of an auxiliary
1D spectrum in each scan of the experiment. Typically, a small-flip-angle
pulse is added at the beginning of the pulse sequence. Based on the
frequency of the maximum of the solvent signal, the field evolution in time
is reconstructed and used to correct the raw data after acquisition, thereby
acting in its principle as a digital lock system. The general applicability
of our approach is demonstrated on 2D and 3D protein spectra during various
situations with a non-linear field drift. SAFR with small-flip-angle pulses
causes no significant loss in sensitivity or increase in experimental time
in protein spectroscopy. The correction leads to the possibility of
recording high-quality spectra in a typical biomolecular experiment even
during non-linear field changes in the order of 0.1 ppm h−1 without the
need for hardware solutions, such as stabilizing the temperature of the
magnet bore. The improvement of linewidths and peak shapes turns out to be
especially important for 1H-detected spectra under fast MAS, but the
method is suitable for the detection of carbon or other nuclei as well.
Optimal closed-loop wake steering – Part 2: Diurnal cycle atmospheric boundary layer conditions

Published: February 2022

Abstract. The magnitude of wake interactions between individual wind turbines depends on the atmospheric stability.
We investigate strategies for wake loss mitigation through the use of closed-loop wake steering using large eddy simulations of the diurnal cycle, in which variations in the surface heat flux in time modify the atmospheric stability, wind speed and direction, shear, turbulence, and other atmospheric boundary layer (ABL) flow features.
The closed-loop wake steering control methodology developed in Part 1 (Howland et al., 2020c, https://doi.org/10.5194/wes-5-1315-2020) is implemented in an example eight turbine wind farm in large eddy simulations of the diurnal cycle.
The optimal yaw misalignment set points depend on the wind direction, which varies in time during the diurnal cycle.
To improve the application of wake steering control in transient ABL conditions with an evolving mean flow state, we develop a regression-based wind direction forecast method.
We compare the closed-loop wake steering control methodology to baseline yaw-aligned control and open-loop lookup table control for various selections of the yaw misalignment set-point update frequency, which dictates the balance between wind direction tracking and yaw activity.
In our diurnal cycle simulations of a representative wind farm geometry, closed-loop wake steering with set-point optimization under uncertainty results in higher collective energy production than both baseline yaw-aligned control and open-loop lookup table control.
The increase in energy production for the simulated wind farm design for closed- and open-loop wake steering control, compared to baseline yaw-aligned control, is 4.0 %–4.1 % and 3.4 %–3.8 %, respectively, with the range indicating variations in the energy increase results depending on the set-point update frequency.
The primary energy increases through wake steering occur during stable ABL conditions in our present diurnal cycle simulations.
Open-loop lookup table control decreases energy production in the example wind farm in the convective ABL conditions simulated, compared to baseline yaw-aligned control, while closed-loop control increases energy production in the convective conditions simulated.
Books: ‘Against my ruins’

Published: February 2022

Much of our cultural heritage has been written on paper and bound into books, in which we attempt to capture our lives in both history and fiction. Yet paper is fragile. What books will remain in two or three thousand years to tell our stories? What will future generations make of our literary ruins, of what we leave behind to be unearthed, classified and interpreted? Which stories will endure? I think about our leavings, imbued with what Bruce Sterling calls “the pathos of lost things” (Sterling 60).
Concentración, diversidad y especialización del cooperativismo en México: aplicación de un Análisis Exploratorio de Datos Espaciales
Authors: Pérez Hernández Carla Carolina , Lara Gómez Graciela , Hernández Calzada Martín
Published: February 2022

El uso de estadísticas sobre cooperativas es una parte esencial para la formulación de políticas, no obstante, en México su utilización se ha limitado a estudios descriptivos. Por lo tanto, el propósito inicial de esta investigación es estimar la concentración, diversidad y especialización del cooperativismo mediante los índices de: Krugman, Hirschman- Herfindahl y la entropía de Shannon. Mientras que por sector cooperativo se calcula el coeficiente de Gini. Posteriormente, se ocupa la técnica de redes para hacer una exploración dentro del espacio de los sectores cooperativos. En un tercer momento se aplica un Análisis Exploratorio de Datos Espaciales (ESDA), con las técnicas denominadas: Índice de Moran e Índice Local de Asociación Espacial (LISA). La primera explica a nivel general como se encuentra distribuido el cooperativismo (en materia de concentración, diversidad y especialización), mientras que la segunda explica localmente el nivel de significancia estadística de los agrupamientos espaciales del mismo fenómeno. Los resultados muestran que tanto la diversidad como la especialización cooperativa tienen una autocorrelación espacial positiva, es decir que manifiestan una distribución espacial agrupada, lo anterior es relevante para la formulación de políticas regionales, ya que se lograron identificar y mapear los lugares que concretamente favorecen y desfavorecen la diversidad y especialización cooperativa. Finalmente, la técnica de redes muestra que el sector cooperativo Agro expresa una coocurrencia marcada con otros sectores cooperativos, lo cual implica la existencia de una proximidad cognitiva, organizacional, social o institucional que favorece la posible diversificación cooperativa hacia otros sectores, lo cual puede ser una vía para ampliar la economía social y solidaria en el país.

Published: February 2022

Let Fq[e] be a ﬁnite ﬁeld of q elements, where q is a power of a prime number p. In this paper, we study the Twisted Hessian curves over the ring Fq[e], where e2 = e, denoted by Ha,d(Fq[e]); (a,d) ∈ (Fq[e])2. Using the Twisted Hessian equation, we deﬁne the Twisted Hessian curves Ha,d(Fq[e]) and we will show that Hπ0(a),π0(d)(Fq) and Hπ1(a),π1(d)(Fq) are two Twisted Hessian curves over the ﬁeld Fq, where π0 and π1 are respectively the canonical projection and the sum projection of coordinates from Fq[e] to Fq. Precisely, we give a bijection between the sets Ha,d(Fq[e]) and Hπ0(a),π0(d)(Fq)×Hπ1(a),π1(d)(Fq).

التوافق بين النص القرآني و وقائع السيرة النبوية : دراسة تطبيقية على منهج نبي الله إبراهيم في الدعوة

Reading and elucidating the Quranic text in accordance with the events of the Sirra is considered a useful means of interpreting and understanding textual connotation in context.

All the prophetic adjudications were his comprehension to Quran.

A researcher can extract methods for daua from the Quranic verses; especially those concerning the prophet Ibrahim.

Muslims are in dire need of those methods since the positivistic ones prevail and lead the world to distress and misery.

There Is an epistemic literature in the Quranic tales of the prophets that help Muslims understanding daua and avoiding them from stigmatizing others as infidel.

Due to the Muslims' current situation, the researcher tries to present a method of daua by analyzing the Quranic text related to the events of Sirra
Gardens in a postsuburb: Community garden governance and ethos in Orange County
Authors: Toda Eiji , Lowe Edward
Published: February 2022

Considerable research has examined the changing values and governing approaches of urban com­munity gardens since the nineteenth century in the United States. However, few studies exist for com­munity gardens located in postsuburban contexts. This study reports the findings from six case stud­ies of community gardens in southern Orange County, California, that asked, how are the themes of garden governance and an overarching garden ethos elaborated at community gardens? Our find­ings suggest that gardens manifest one of three governance approaches which we labeled anarchic, democratic, and corporate. In addition, we found two values frameworks or garden ethoses among these gardens. One is a community ethos oriented toward realizing values promoting greater commu­nity engagement, and the other is an individualistic ethos oriented toward promoting the value of gar­dening as an independent activity for each gardener in their plot. We argue that just as gardens in the inner city have been sites to address urban prob­lems, gardens in postsuburban environments might also address perceived shortcomings in postsubur­ban regions. Our findings also suggest that com­munity gardens, particularly in newer suburban developments, reflect a shift in the utopian visions of postsuburban planning away from a consumerist lifestyle to a newer one that enables access to nature and sustained social connections among residents.

Physics is one of the subjects taught in Senior High School (SMA) education. Physics learning is often seen as an abstract science that is presented in a theory that is less attractive and seems difficult to master and understand. To solve the problem of learning physics, one of the models that is expected to increase the activeness and learning outcomes of students is to apply the Problem Based Learning (PBL) learning model. The use of variations in the PBL learning model with teaching aids and conducting experiments is also considered to make students not easily bored in learning physics and makes the material tend to be easily understood by students. For this reason, a study was conducted with the aim of knowing the effect of the Problem Based Learning (PBL) learning model assisted by teaching aids on the material of spring force on student learning outcomes. The data analysis technique in this research is using normality test and hypothesis testing. The results of the normality test showed that the data were normally distributed, and the results of the hypothesis test showed that the application of the PBL learning model assisted by teaching aids proved to have an effect on improving student learning outcomes.
Financial Innovation and Demand for Money in Nigeria
Authors: Jonah Joshua Nsikak , Egbe Idaka Sunday , Richard Eja Basil
Published: February 2022

This study examined the impact of financial innovation on money demand in Nigeria, using quarterly time series for the period 2009-2019. The dependent variable was money demand, represented by broad money, while the independent variable was financial innovation represented by modern payment channels such as volume of Automated Teller Machines (ATMs) transactions, volume of Point of Sales (POS) transactions, volume of Internet banking transactions, and volume of Mobile banking transactions. The study employed the ordinary least squares (OLS) regression technique as the estimation method within the cointegration, granger causality, and error correction modelling. The result obtained showed that financial innovation has mixed impact on money demand in Nigeria during the period of analysis. For instance, financial innovation has positive impact on money demand through volume of ATM transactions in the current period, two periods lagged of volume of mobile banking transactions, current period and one period lagged of volume of internet banking transactions, and current period’s volume of Point of Sales (POS) transactions in Nigeria. On the other hand, financial innovation has negative impact on money demand through one period lagged of volume of point of sales in Nigeria. On the stability of the demand for money function, the result of the stability tests based on the CUSUM test and CUSUM of squares test showed that the demand for money function was stable during the evaluation period. The study recommended that monetary policy strategy of the central bank of Nigeria (CBN) should be fine-tuned to ensure it is well suited to deal with the challenges posed by financial innovation by way of proliferation of sophisticated payment channels.
Rodomonte e Corsamonte devono morire. Erocità, morte e fine del racconto a metà Cinquecento
Authors: Comelli Michele
Published: February 2022

Il contributo intende indagare il rapporto tra la nozione di eroe, la morte e la fine del racconto nella difficile transizione dal romanzo al poema eroico a metà Cinquecento, prima dell’esperienza tassiana. In particolare, vengono indagati e posti a confronto, al fine di metterne in rilievo gli elementi di continuità e discontinuità, i duelli risolutivi dell’Orlando Furioso di Ludovico Ariosto e dell’Italia liberata dai Goti di Gian Giorgio Tissino, che rappresentano due poli opposti ma interdipendenti della suddetta transizione. Nei duelli tra Ruggiero e Rodomonte, e nella disfida di Lipadusa, nel poema ariostesco, e nella parabola di Corsamonte e nello scontro finale narrati da Trissino, si concretizza, attraverso la dialettica epos/romanzo, un nuovo modello eroico, in grado di rispondere alle esigenze della modernità.
Archeologie della presenza: Digital liveness, vanisch liveness e la mediatizzazione della presenza

Questo lavoro intende mostrare come la questione della liveness e, con essa la questione della presenza, possa essere posizionata piuttosto alla fine del secolo scorso. Attraverso uno sguardo mediarcheologio il lavoro intende chiarire come la liveness è figlia di negoziazioni continue tra spazio, media e corpo umano. Tale negoziazione è chiaramente oggi più profonda e complessa perché figlia di forme di mediatizzazione profonda del mondo e delle arti performative. Per questo motivo il contributo intende infine ragionare intorno al concetto di vanish liveness ovvero quelle forme di liveness digitale, prodotte da piattaforme come Instagram, Snapchat, TikTok, Clubhouse, in cui l’evento live non viene archiviato ed è fruibile, proprio come l’evento dal “vivo”, soltanto da coloro che ne condividono un tempo.
Foundation for behaviour management: A systems approach
Authors: Andrews Diane , Clarke Trevor
Published: February 2022

This article outlines the development and implementation of a project designed to help a school reflect on how well it has developed supportive behaviour management systems. The programme further encourages the school to implement more functional systems. When the local Group Special Education (GSE) office was offered an opportunity to develop some innovation projects, a proposal for looking at behaviour management as a school-wide systemsintervention was developed. The conceptual base was to focus on six targeted school systems believed to be the foundations for functional behaviour management, profile them for a school, report them in a way that has meaning and work with the school in improving functionality.The project has been used in seven schools in Southland and one in Canterbury. All the schools reported positive outcomes, and some schools made major advances in developing functional behaviour management systems.
Getting to the heart of the matter: Examining the efficacy of a whole-school approach to behaviour management.
Authors: Scott Bridget
Published: February 2022

This article reviews literature on whole-school approaches to behaviour management in order to address these questions: How is a whole-school approach to behaviour managementdefined in the literature? What are the key principles that make a whole-school approach effective? What are the key systems that make a whole-school approach effective? Is theinvolvement of students an important aspect of a whole-school approach? The review highlights current work on belonging, which shows that a person’s sense of belonging has an impacton their engagement and therefore achievement in a school setting. For a whole-school approach to be effective it must have a positive impact on the engagement of the students.The findings of this review suggest that schools implementing a whole-school approach must first examine the quality of the relationships within their school as these have an impact onstudents’ experiences of belonging. The principles and values about relationships that a school holds will shape the kind of whole-school approach they develop.

Mangroves are tropical coastal vegetation communities dominated by several unique tree species that can be affected by tides. Damage to mangrove forests can be caused by two main factors, namely human activity factors and natural factors. The purpose of this study was to analyze the structure of mangrove vegetation by looking at density, frequency, Impact Value Index (IVI) and species diversity (H ') on the coast of Dambalo Village, Tomilito Sub-district, North Gorontalo District. The method used is a combination of the path method and the checkered line method so that measuring squares are created within the paths. The results showed that the number of mangrove diversity was 11 species, with the Importance Value Index at the tree level of the Rhizophora apiculata species having the highest value of 61.28% and the seedling phase with the same species Rhizophora apiculata having the highest index of importance of 29.80%. The main conclusion from this research is that the mangrove vegetation structure has an abundant level of species diversity. This shows that the index of species diversity in mangrove vegetation is H '= 2.2692 that species diversity is abundant.
The Characteristics and Complexity of the Nigerian Security Challenges: The Need for a New Strategy
Authors: Monday Etebom John
Published: February 2022

Nigeria, the world sixth most populous nation, is faced with an array of security challenges like most developing nations in West Africa, North Africa and the Middle East. The level of insecurity in Nigeria has risen to an unprecedented level. No part of the six geopolitical zones or regions could be said to be safe. The security challenges in each region of the country are slightly integrated and peculiar as well. From insurgency, terrorism, banditry to cattle rustling in the North to farmer-herder conflict, kidnapping, bank robbery, secessionist and separatist agitations in the South of the country. No part of the country is free of insecurity. The study investigated the characteristics of the security challenges confronting the country and analyzed its peculiarities in the six geopolitical zones. The study revealed that the security challenges ravaging the country were domestically created and interrelated. Inversely, it would require some domestic dynamic military cum pragmatic socio-political approaches to quell. The study adopted a quantitative method of analysis and drew from the benefit of insight and experience of the author who had served in the Nigerian military. It further recommended new inclusive security and political strategies for quelling the uprising in the country.
Maximum Liquefaction of Gases Revisited
Authors: PITANGA MARQUES Rui , BORDONİ P.r.g. , PINHO M. O.
Published: February 2022

Joule-Thomson liquefiers are the commonest machines to liquefy gases. Over the years, countless number of articles have been published on the subject. Dozens of 1st and 2nd law analyses were carried out on Joule-Thomson liquefaction cycles. And yet an aspect of purely theoretical interest seems to have passed unnoticed, namely: for a given volume of gas, what conditions should be fulfilled to achieve maximum liquefaction without considering engineering details of design equipment and the highly irreversible character of work-consuming devices, heat exchangers, heat leaks and the throttling process. This work addressed this issue by applying the 1st law analysis and elementary calculus prescriptions to a simple Linde-Hampson liquefying process. The same approach could be applied to other liquefying cycles. As is well-known, for a given mass flow rate of a gas, maximum fraction liquefied occurs when the pre-cooling temperature, Ti , and initial pressure, Pi , lie on the inversion curve. It has been proved that this is only true if an additional condition is fulfilled. Expressions for it were derived for the van der Waals, RKS and PR equations of state.
