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.

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.

Decolonising Arabic Language Teaching: A Case Study
Authors: Columbu Alessandro 
Published: February 2022

Since the early 2000s Arabic has become an increasingly popular language at academic level across Europe and North America, with high numbers of students enrolling on a variety of programmes offering Modern Standard Arabic – as well as local varieties of Arabic, commonly known as ‘āmmiyya – as the target language (Dickins and Watson 2006, 108; Ryding 2006, 13; Mohamed 2021b, 59). The increasingly high demand for this language has resulted in unprecedented progress in the variety of learning materials available for both teachers and learners. Such developments have largely taken place in the United States, where most textbooks such as the Al-Kitaab series are designed and printed. This paper employs decolonisation and post-colonial theory to look at the ideological implications of the political agendas implicit in popular and widely adopted textbooks and their proposed content for teaching Arabic as a foreign language. Relevant examples from the Al-Kitaab series – one of the most successful and widely adopted textbooks at university level in the UK – show the role of Arabic language teaching materials in perpetuating patterns of European and North American cultural hegemony, making the case for rethinking Arabic language teaching at academic level.
Comparative study on anatomical traits and gas exchange responses due to belowground hypoxic stress and thermal stress in three tropical seagrasses
Authors: Soonthornkalump Sutthinut , Ow Yan Xiang , Saewong Chanida , Buapet Pimchanok 
Published: February 2022

Background
The ability to maintain sufficient oxygen levels in the belowground tissues and the rhizosphere is crucial for the growth and survival of seagrasses in habitats with highly reduced sediment. Such ability varies depending on plant anatomical features and environmental conditions.

Methods
In the present study, we compared anatomical structures of roots, rhizomes and leaves of the tropical intertidal seagrasses, Cymodocea rotundata, Thalassia hemprichii and Halophila ovalis, followed by an investigation of their gas exchange both in the belowground and aboveground tissues and photosynthetic electron transport rates (ETR) in response to experimental manipulations of O2 level (normoxia and root hypoxia) and temperature (30 °C and 40 °C).

Results
We found that C. rotundata and T. hemprichii displayed mostly comparable anatomical structures, whereas H. ovalis displayed various distinctive features, including leaf porosity, number and size of lacunae in roots and rhizomes and structure of radial O2 loss (ROL) barrier. H. ovalis also showed unique responses to root hypoxia and heat stress. Root hypoxia increased O2 release from belowground tissues and overall photosynthetic activity of H. ovalis but did not affect the other two seagrasses. More pronounced warming effects were detected in H. ovalis, measured as lower O2 release in the belowground tissues and overall photosynthetic capacity (O2 release and dissolved inorganic carbon uptake in the light and ETR). High temperature inhibited photosynthesis of C. rotundata and T. hemprichii but did not affect their O2 release in belowground tissues. Our data show that seagrasses inhabiting the same area respond differently to root hypoxia and temperature, possibly due to their differences in anatomical and physiological attributes. Halophila ovalis is highly dependent on photosynthesis and appears to be the most sensitive species with the highest tendency of O2 loss in hypoxic sediment. At the same time, its root oxidation capacity may be compromised under warming scenarios.

Authors: Cobbinah P. , Abengmeneng C. S. 
Published: February 2022

Nursery establishment for healthy seedlings is an integral part of afforestation and reforestation projects. Plant parasitic nematodes (PPNs) are amid the destructive pathogens that greatly threaten forest nurseries. This study assesses forest nursery operations and knowledge of PPNs of four forest districts of Ashanti region of Ghana, namely Juaso, Mankranso, Offinso, and Nkawie. Respondents comprised only forestry staff involved in managing forest nurseries. A Structured and semi-structured interview schedule was employed for data collection. Data obtained were analyzed using the Statistical Package for Social Science version 23. Descriptive statistics were used and means presented using tables and graphs. From the study, all the respondents (100%) established temporary nursery to meet seedlings demand. Majority of the respondents (83.3%) sourced soil from abandoned refuse dump while few (16.7%) collected top soils from unfarmed sites for raising seedlings. Disease occurrence in the nursery was observed by majority (75%) of the respondents while most (66.7%) of them had no idea of the causes of the diseases observed. Greater proportion (66.7%) of the respondents moreover had no knowledge of PPNs and therefore were unaware of their damage potential. Organising seminars and workshops for nursery managers on proper operations and awareness of PPNs to enhance their knowledge is recommended.

A Review on the Incidence of Conjunctivitis Seen in COVID-19 Disease
Authors: Agarwal Isha , Bajpayee Neha 
Published: February 2022

Conjunctivitis is a pathological problem of the eye. It can be defined as an inflammatory condition consisting of membranes and conjunctiva. It can be caused by several organisms and has several possible causes. It may be caused by bacteria, viruses, fungus, or protozoa and may also occur due to infection. Conjunctivitis is a prevalent issue in developing and developed countries. In layman's language, it can also progress to red-eye very commonly and, therefore, the red disease. The treatment of conjunctivitis includes no such medications since some of them are self-healing. However, some require topical steroids to relieve the inflammation—moreover, antihistaminics, mast cell stabilizers, and NSAIDs. In bacterial conjunctivitis, antibiotics are given according to the causative organisms.
Since the virus outbreak started in India and the people of our country underwent several restrictions, including strict lockdowns, we people are bound to use electronic gadgets and online learning platforms, which has exceeded our screen time to several folds. This has increased the prevalence of different eye disorders causing refractive errors, vision loss, dry eye, eyes watering, etc. Even the toddlers who should ideally be put into a playschool and be physically active and kept away from any screen are bound to sit in front of their laptops for hours to learn something. Also, sometimes a patient may present with conjunctivitis as the only symptom. Therefore, this review article will shed light on the above sentences and discuss the severity.
