Physical activity programmes in the workplace and the role of organisational culture: A systematic review of current evidence
Authors: Lucas Alex , Wade Matthew , Wagstaff Christopher
Published: December 2020

Evidence links physical activity (PA) participation to mental wellbeing and work performance, leading organisations to implement workplace PA programmes. Workplace factors, like organisational culture (OC), have been associated with PA programme implementation, usage, and sustainability. Yet, no synthesis of this work exists, perhaps contributing to the limited consideration of OC in PA programmes. The aim of this review was to examine the knowledge regarding OC and PA workplace programmes and identify literature themes and gaps to provide recommendations for future research and practical implementation. A systematic review of health and social science databases was conducted, with 40 studies reviewed at full text. Study findings indicated that OC manifested through extant themes and influenced programmes through senior leadership, normative behaviours, acceptance and prioritisation, and organisational policies. Programmes varied in length, type, and quality of PA data metrics collected. Recommendations include: using socio-ecological and employee-centred approaches in programme research and development; improving programme measurement and evaluation to expand the evidence-base and; developing tangible guidance for employers to support programme implementation. OC plays an important role in workplace PA programme success, yet evidence informed decisions, improving measurement, and producing clear guidance is required, leading to ongoing research and developing high-quality programmes.
Sociology of political conflict
Authors: Nikovskaya Larissa
Published: December 2020

The article deals with the sociological aspects of the analysis of political conflict related to the socio-structural and subjective foundations of political processes and relations. It is shown that many problems and contradictions in the social sphere, such as social polarization, excessive inequality, poverty and violation of the principles of social justice, deprivation of basic needs and interests, unstable labor employment significantly determine the field of politics and are projected on the object and subject of political conflict, weighing down their course and positive outcomes. The insolubility of social problems and contradictions, their encapsulation cause either a decrease in the population's interest in politics, in the effectiveness of democratic institutions, contribute to the widening of the gap between the «private» and «public», generate a sense of political alienation and powerlessness, or push to meet basic needs beyond the existing social norms and political institutions, to destructive forms of resolving political conflicts, which leads to a loss of control of society and social catastrophe. The sociological analysis of conflict interactions based on the predominance of horizontal connections and relationships contributes more to maintaining a dynamic balance in society and realizing the positive potential of political conflict, as it differs in flexible intra-group connections and mobile inter-group barriers in the socio-political system. Excessive class divisions and inequality tend to vertical polarization of society, which strengthens the «discontinuous» lines of interaction between the «top» and «bottom», makes the dichotomy «rule-submission» rigid, and reduces the possibilities of dialogical plasticity and flexibility of the political system.
International negotiations as a social and humanitarian resource in world politics
Authors: Lebedeva Marina
Published: December 2020

The article considers international negotiations as a resource of influence and creation in world politics, which is part of the social and humanitarian resource. The article analyzes the negotiation practice and research of international negotiations, starting from the second half of the twentieth century, i.e. from the moment when international negotiations receive intensive development. It is shown that at this time a huge practical and research experience was accumulated on the technology of negotiations, the role and place of negotiations in the world, which made up a social and humanitarian resource for world politics. At the end of the twentieth – beginning of the twentieth centuries there is a decline in negotiation activity and, accordingly, decline research on international negotiations, which was caused by: 1) a change in the nature of conflicts that have largely ceased to be interstate in nature and which began to arise on ethnic and religious grounds with many decentralized participants; 2) a significant reduction in the role of Russian-American relations in the world after the collapse of the USSR. Namely, the Russian-American negotiations, primarily in the field of disarmament, were the most important in international relations of the second half of the twentieth century. As a result, in the 21 st century, the number of international negotiations not only decreased, but treaties reached in the past began to be denounced, primarily by the United States. It is shown that this situation is caused by deep processes of transformation of the political organization of the world, covering its various levels, both national and supranational. As a result, a situation of uncertainty and unpredictability is created, which does not contribute to the search for negotiated solutions. However, the political organization of the world can only be transformed through negotiations. Given the scale of this transformation and the huge number of actors in the modern world, international negotiations will become of great importance, serving as a resource for building a new political organization of the world.

Published: December 2020

Reading literacy competence is an educational problem that requires special attention and needs continuously improved. Reading literacy should begin earliest in the family environment. After entering the school, teachers need to work together with parents to raise a reading culture. Public of Elementary School (SDN) Pulau Kelapa 01 Pagi has not involved parents yet before in encouraging students to read. Therefore, the purposes of this activity are to educate parents about the importance of reading literacy and evaluating the Literacy Project assigned to parents. This community service activity uses the method to educate parents with tutorials, discussion, and experience sharing techniques. After opening the mindset and giving the knowledge about literacy reading, participants, namely the parents of 29 fourth grade students, were given a Literacy Project assignment for a week. This activity has increased the attention of parents about the importance of reading and fostering reading through the family environment. However, in fact, in the implementation of the Literacy Project, parents have not yet fully carried out. Parents still need to implement reading habits at home. In this case, the school needs to collaborate with parents in creating a pleasant literacy atmosphere through various literacy activities in a sustainable manner. Universities can help realize these programs.

Published: December 2020

El Zika es un flavivirus transmitido principalmente por la picadura de mosquitos infectados. Los signos y síntomas pueden incluir erupción cutánea, prurito, fiebre, dolor de cabeza, artralgia, mialgia, conjuntivitis, dolor lumbar y dolor retro orbitario.  Se trata de un virus teratógeno, el cual puede provocar microcefalia, entre otras malformaciones congénitas; además se asocia a síndrome de Guillain Barré en adultos. Debido al riesgo de transmisión intrauterina, es importante realizar ecografías seriadas a las gestantes para controlar el crecimiento fetal y la neuroanatomía. Su diagnóstico se realiza mediante sospecha clínica y se confirma con pruebas de amplificación de ácidos nucleicos y pruebas de anticuerpos IgM. Eliminar los lugares donde el mosquito pone huevos, principalmente contenedores artificiales que contienen agua además del uso de repelentes tópicos contra insectos, es de vital importancia como medidas de prevención. El tratamiento es sintomático, mediante medidas de soporte como hidratación, analgesia y antihistamínicos.

Authors: Cowan Katie
Published: December 2020

This study examined public reactions on Twitter about Donald Trump’s messages regarding the COVID-19 pandemic, which created fear in the public, therefore promoting an increase in panic buying. A content analysis of 52 relevant tweets between March 16 and April 3 identified several themes of public reactions to the messages that were transmitted by Donald Trump about COVID-19, including: incompetence, harm, untrustworthiness, political agenda, misinformation, distraction, lack of empathy, and the dismissal of solving panic buying. The most prevalent theme was the incompetence of Donald Trump, which created fear; therefore panic buying increased among the public.
Blasé Attitude, Hyperreality, and Social Media
Authors: Le Hannah
Published: December 2020

Though there is much to gain through technological development, it is also necessary to critique the ubiquitous presence of devices in social life and the overstimulation they bring. The increasing mediation of reality through applications such as Instagram could blur the division between the ‘real’ world of everyday life and a ‘hyperreality’ fostered by such applications. Using concepts from theorists Jean Baudrillard and Georg Simmel, this paper presents a critique of the overstimulation of information through social media. With continuous and repetitive material being recycled online, it is discussed how a blasé attitude is used to protect oneself from being informationally overwhelmed.
Lennon vs. McCartney
Authors: Kroetch Kimberly
Published: December 2020

In this analysis, the chord progressions used in songs by the Beatles are modelled as Markov chains to identify potential differences between songs for which John Lennon had more influence and those for which Paul McCartney had more influence. A preliminary comparison of random samples of songs from each artist did not identify noteworthy differences between Lennon and McCartney; most pieces resulted in regular Markov chains. This analysis then focusses on two songs from the Beatles – “Norwegian Wood”, primarily written by John Lennon, and “Good Day Sunshine”, primarily written by Paul McCartney – which deviated from this pattern. Similar patterns were found between the two songs despite major differences in the chords that made up each state space. In general, however, McCartney’s song had more variety in terms of the number of chords used and the paths taken between tonic chords.

Vladimir Klavdeevich Arsen’ev is one of the best-known figures of
the Russian Far East, and yet the scholarly literature — particularly in English — on his historical significance is surprisingly thin. Literary scholars, drawn by Arsen’ev’s famous novel Dersu Uzala, and cinema scholars, intrigued by Akira Kurosawa’s masterful film adaptation of that work, have most critically engaged with the Russian polymath’s work (Arsen’ev was, after all, a military officer, an explorer, an author, an ethnographer, a bureaucrat, and more). Much more rarely have scholars assessed Arsen’ev’s important role as an actor in and commentator on Russian colonization in the Far East. This special collection of articles in Sibirica makes a start at that assessment, identifying several areas where a study of Arsen’ev’s life and writings can illuminate important aspects of the region’s early twentieth-century history.

Authors: Jiang Shangrong , You Hong , Zhao Weijing , Zhang Min
Published: December 2020

BACKGROUND: Robot-assisted therapy (RT) has become a promising stroke rehabilitation intervention. OBJECTIVE: To examine the effects of short-term upper limb RT on the rehabilitation of sub-acute stroke patients. METHODS: Subjects were randomly assigned to the RT group (n= 23) or conventional rehabilitation (CR) group (n= 22). All subjects received conventional rehabilitation therapy for 30 minutes twice a day, for 2 weeks. In addition, the RT group received RT for 30 minutes twice a day, for 2 weeks. The outcomes before treatment (T0) and at 2 weeks (T1) and 1 month follow-up (T2) were evaluated in the patients using the upper limb motor function test of the Fugl-Meyer assessment (FMA) the Motricity Index (MI), the Modified Ashworth Scale (MAS), the Functional Independence Measure (FIM), and the Barthel Index (BI). RESULTS: There were significant improvements in motor function scales (P< 0.001 for FMA and MI) and activities of daily living (P< 0.001 for FIM and BI) but without muscle tone (MAS, P> 0.05) in the RT and CR groups. Compared to the CR group, the RT group showed improvements in motor function and activities of daily living (P< 0.05 for FMA, MI, FIM, BI) at T1 and T2. There was no significant difference between the two groups in muscle tone (MAS, P> 0.05). CONCLUSIONS: RT may be a useful tool for sub-acute stroke patients’ rehabilitation.
RESTORASI LAHAN RAWA GAMBUT MELALUI METODE REWETTING DAN PALUDIKULTUR
Authors: Triadi L. Budi Budi
Published: December 2020

Degradasi di lahan rawa gambut umumnya diakibatkan oleh alih fungsi lahan dan pemilihan komoditas yang tidak tepat. Alih fungsi lahan yang disertai dengan pembuatan drainase tanpa perencanaan yang matang menyebabkan lahan menjadi kering, mudah terbakar, subsiden, banjir, emisi CO2 dan permasalahan sosial-ekonomi.Penelitian ini dilakukan melalui studi literatur terkait persoalan dan solusi pemulihan lahan gambut terdegradasi melalui restorasi hidrologi dengan metode rewetting (sekat/canal blocking) dan penanaman jenis tanaman yang tidak membutuhkan drainase (paludikultur).Terdapat empat tipe sekat yang biasa digunakan, Â yaitu sekat papan, sekat isi, sekat plastik, dan sekat geser. Pemilihan tipe sekat sangat tergantung kepada kondisi bio-fisik, dimensi kanal, topografi gambut, ketersediaan material dan aksesibilitas ke lokasi penabatan. Dari penelitian ini diketahui adanya korelasi yang kuat antara keberadaan sekat terhadap penambahan ketinggian muka air tanah, dimana sekat bermanfaat untuk menaikkan muka air tanah dan melembabkan tanah.Selanjutnya, dalam penerapan paludikultur, diketahui bahwa komoditas tertentu lebih tahan terhadap genangan namun tetap memiliki nilai ekonomi seperti: Metroxylon spp, Nypa fruticans Wurmb, Alseodaphne spp. dan Nothaphoebe spp., dan Shorea spp. Agar dapat bertahan hidup jenis-jenis tanaman tersebut harus dipilih dan disesuaikan dengan ketinggian air yang terdapat di lahan gambut.Â Kata kunci: Gambut, paludikultur, sekat kanal, restorasi, muka air tanahIn general, degradation on peatlands is mainly caused by excessive conversion and selection of commodities that cannot grow in wet condition. Conversion of peatlands and extreme canalization have become major threats to peatlands which leads to peat fire, subsidence, flooding, green house emission, as well as economic and social problems.This study was obtained from literature study on current problems and solutions of degraded peatlands through peatland hydrology restoration by rewetting method (canal blocking) and cultivation of species that do not require drainage. There are four types of dams that are often used to control water flows, plank dam, composite dam, plastic dam, and sluice. The selection of dam is highly dependent on bio-physical condition, dimensions of canals, peat-topography, availability and accessibility of transportation to the dam site. This research shows that there is strong correlation between canal blocking and the increasing of ground water level, where canal blocking is useful for raising the water table and moisturizing the soil.In the implementation of paludiculture, the certain species / commodities can survive Â to wet condition, and also have economic value such as: Metroxylon spp, Nypa fruticans Wurmb, Alseodaphne spp. dan Nothaphoebe spp), dan Shorea spp. In order to survive the type of plants has to be selected and adjusted to the condition of peatlands water level. Keywords : Peatlands, paludikultur, canal blocking, restoration, ground water level
Luciano Bianciardi e l’uva della collera
Authors: Raveggi Patrizia
Published: December 2020

Luciano Bianciardi pubblicò per testate diverse, negli anni tra il 1944 e il 1971, quasi mille articoli di natura estremamente varia, (elzeviri, rubrica delle lettere, critica televisiva, inchieste, cronache locali, pezzi sportivi), oltre ai suoi più noti romanzi e a opere di divulgazione storica dell’epopea risorgimentale: il tutto scritto nelle ore di riposo da quello che dal 1954 in avanti costituì il suo vero lavoro e fonte di reddito, un immane impegno traduttorio.
Questo contributo individua nel percorso creativo dell’autore in parola, caratterizzato dalla tecnica del riuso di testi propri e altrui, da lui o tradotti o consultati per studio, una immagine balenatagli in mente durante il servizio militare, in guerra, sotto un bombardamento e da lui annotata poco a valle dell’evento in un suo Diario; tale immagine periodicamente riaffiora in altri scritti fino a fungere da conclusione del romanzo che lo avrebbe reso famoso.

Published: December 2020

Introducción: la Gimnasia Abdominal Hipopresiva es un método creado en la década de los 80 por el Dr. Marcel Caufriez en el ámbito de la reeducación postparto. Actualmente es una técnica muy popularizada, sin embargo, hasta el momento existe poca evidencia en la literatura científica que avale la eficacia de dichos ejercicios.

Objetivo: revisar la evidencia publicada en los últimos cinco años sobre los efectos de los ejercicios abdominales hipopresivos.

Método: para la realización de este trabajo se llevó a cabo una revisión de la literatura en las bases de datos PubMed, Medline, CINAHL, Scopus, Web Of Science, SPORTDiscus, Science Direct, PEDro y Dialnet en febrero de 2020. Se incluyeron artículos publicados en los últimos cinco años, y en idioma inglés  o español.

Resultados: Se obtuvieron 16 artículos. Los estudios analizados evalúan el efecto de los abdominales hipopresivos sobre el suelo pélvico, abdomen, incontinencia urinaria, dolor lumbar, escoliosis y factores metabólicos.

Conclusiones: los ejercicios hipopresivos pueden ser utilizados como método complementario al tratamiento clásico de fortalecimiento de la musculatura del suelo pélvico o abdominal. Las conclusiones de esta revisión se deben tomar con precaución debido a las limitaciones que presenta, como la baja calidad de los artículos analizados.

Türkiye'nin Bölgesel Doğal Gaz Merkezine Dönüşme Potansiyeli
Authors: KAKIŞIM Cemal
Published: December 2020

Türkiye, 1976 yılında devreye giren Irak-Türkiye Petrol Boru Hattı ile küresel enerji ticaretinde ilk defa transit ülke olarak rol almaya başlamıştır. Bu boru hattı ile Türkiye’nin ulusal petrol talebi karşılanırken, Irak petrolü Türkiye’nin Doğu Akdeniz’deki limanı üzerinden dünya enerji piyasalarına ihraç edilmiştir. Daha sonra yeni oluşturulan boru hatlarıyla Azerbaycan petrolünü de Türkiye’ye üzerinden uluslararası pazarlara ulaştırılmıştır. Türkiye, son dönemde geliştirilen projelerle petrolden sonra doğal gaz alanında da transit ülke haline gelmeye başlamıştır. Ancak Türkiye’nin enerji politikasının hedeflerinden biri, transit ülke olmanın da ötesinde bölgesel bir enerji merkezine dönüşmektir. Enerji merkezi olabilmesinin önünde ise bazı engeller bulunmaktadır. Türkiye’nin yeterli enerji kaynaklarına sahip olmaması, enerji üretiminin oldukça sınırlı olması, doğal gaz ithalatına ve tedarikçi ülkelere önemli ölçüde bağımlı olması, enerji arz güvenliği riskinin yüksek olması, gelişmiş bir enerji altyapısına ve rekabete açık, serbest bir enerji piyasasına sahip olmaması enerji merkezi olabilmesini engelleyen unsurlar arasında öne çıkmaktadır. Bu çalışmada, Türkiye’nin doğal gaz görünümü, devam eden uluslararası boru hattı projeleri, mevcut doğal gaz altyapısı ve doğal gaz piyasası göz önünde bulundurularak doğal gaz merkezi olma potansiyeli değerlendirilecektir.

Metal-organic 1D-coordination polymers, having unique electronic and optical properties, are expected to be a novel advanced functional material capable of fabricating smart plastics, films, and fibers. In this study, we have synthesized a novel metal-organic 1D-coordination polymer composed of a phenylene-bridged bipyrrole bearing N-alkylimino groups (BPI) and palladium(II) ion. The BPI and Pd(II) form square planar bis(bidentate) complex to form a metal coordinated π-conjugation polymer (Poly-BPI/Pd). It is stable in solutions at room temperature, and allowed measurement of its average molecular weight in SEC (Mw = 106,000 and Mn = 18,000, Mw/Mn = 5.88). It also provided a reversible multi redox profile in cyclic voltammetry, most likely originating from strong π-electronic interactions between the BPI components via Pd ion. A variety of substituent groups can be attached to the imino-nitrogens of BPI. A coordination polymer composed of a BPI derivative bearing chiral alkyl chains and Pd(II) showed strong circular dichroism (CD) in the solution due to the unidirectional chiral conformation of the BPI components in the polymer backbone.

Prokaryotes play an important role in biogeochemical cycling in marine ecosystems, but little is known about their diversity and composition, and how they may contribute to the ecological functioning of coastal areas in the South Mediterranean Sea. This study investigated bacterial and archaeal community diversity in seawater samples along the Tunisian coast subject to important physicochemical disturbances. The 16S amplicon sequencing survey revealed higher prokaryotic diversity in the northern Tunisian bays than in southeastern waters (Gulf of Gabès). The major taxonomic groups identified in all samples wereAlphaproteobacteria(40.9%),Gammaproteobacteria(18.7%), Marine Group IIEuryarchaeota(11.3%), andCyanobacteria(10.9%). Among them, the relative abundance ofAlteromonadales,Prochlorococcus, and some clades ofPelagibacterales(SAR11) significantly differed between the northern and the southern bays, whereas no difference was observed across coastal waters in the archaealCandidatusPoseidoniales (MGII),Synechococcus, andPelagibacteraceae(SAR11 clade Ia), for which no relationship was observed with the environmental variables. BothPseudoalteromonasandAlteromonaslevels increased with the increasing salinity, density and nutrients (NH4+and/or PO43–) gradients detected toward the southern waters, while the SAR11 clades Ib and IV andProchlorococcus, decreased in the shallow, salty and nutrient-rich coastal waters of the Gulf of Gabès.Rhodobacteraceaewas positively correlated withSynechococcusand chlorophyll levels, suggesting a relationship with phytoplankton biomass. The present study provides the first insights into planktonic prokaryotic community composition in the South Mediterranean Sea through the analysis of Tunisian seawaters, which may support further investigations on the role of bacterioplankton in the biogeochemistry of these ecosystems.

Background: The HIV associated mortality is decreasing in most countries due to the widespread use of antiretroviral therapy. However, HIV-associated neurocognitive disorder (HAND) remains a problematic issue that lowers the quality of life and increases the public health burden among people living with HIV. The prevalence of HAND varies across studies and selected samples. Therefore, we aimed to quantitatively summarize the pooled prevalence of Frascati-criteria-based HAND and to explore the potential demographic, clinical, and immunological factors.

Methods: A comprehensive literature search in PubMed/Medline, Web of Science, Embase, and PsycINFO was performed. A random-effects meta-analysis was conducted using the event rate (ER) for the estimation of the incidence of HAND. Subgroup meta-analyses were used to evaluate between-group differences in categorical variables. Meta-regression with the unrestricted maximum likelihood (ML) method was used to evaluate associations of continuous variables.

Results: Eighteen studies whose sample sizes ranged from 206 to 1555 were included in the final analyses. The estimated prevalence of HAND, ANI, MND and HAD were 44.9% (95% CI 37.4–52.7%), 26.2% (95% CI 20.7–32.7%), 8.5% (95% CI 5.6–12.7%), 2.1% (95% CI 1.2–3.7%), respectively. Factors associated with HAND were percent female, current CD4 count, education level and country development level (all ps < 0.05).

Conclusion: Longitudinal cohort and multimodal neuroimaging studies are needed to verify the clinical prognosis and the underlying neurocognitive mechanism of HAND. In addition, it is urgently necessary to establish a standardized HAND diagnostic process.

Amyloid proteins are involved in many neurodegenerative disorders such as Alzheimer’s disease [Tau, Amyloid β (Aβ)], Parkinson’s disease [alpha-synuclein (αSyn)], and amyotrophic lateral sclerosis (TDP-43). Driven by the early observation of the presence of ordered structure within amyloid fibrils and the potential to develop inhibitors of their formation, a major goal of the amyloid field has been to elucidate the structure of the amyloid fold at atomic resolution. This has now been achieved for a wide variety of sequences using solid-state NMR, microcrystallography, X-ray fiber diffraction and cryo-electron microscopy. These studies, together with in silico methods able to predict aggregation-prone regions (APRs) in protein sequences, have provided a wealth of information about the ordered fibril cores that comprise the amyloid fold. Structural and kinetic analyses have also shown that amyloidogenic proteins often contain less well-ordered sequences outside of the amyloid core (termed here as flanking regions) that modulate function, toxicity and/or aggregation rates. These flanking regions, which often form a dynamically disordered “fuzzy coat” around the fibril core, have been shown to play key parts in the physiological roles of functional amyloids, including the binding of RNA and in phase separation. They are also the mediators of chaperone binding and membrane binding/disruption in toxic amyloid assemblies. Here, we review the role of flanking regions in different proteins spanning both functional amyloid and amyloid in disease, in the context of their role in aggregation, toxicity and cellular (dys)function. Understanding the properties of these regions could provide new opportunities to target disease-related aggregation without disturbing critical biological functions.

Published: December 2020

The incidence of thyroid cancer (TC) is rapidly increasing worldwide. The diagnostic accuracy and dynamics of TC need to be improved, and traditional treatments are not effective enough for patients with poorly differentiated thyroid cancer. Exosomes are membrane vesicles secreted specifically by various cells and are involved in intercellular communication. Recent studies have shown that exosomes secreted by TC cells contribute to tumor progression, angiogenesis and metastasis. Exosomes in liquid biopsies can reflect the overall molecular information of tumors, and have natural advantages in diagnosing TC. Exosomes also play an important role in tumor therapy due to their special physicochemical properties. TC patients will benefit as more exosome patterns are discovered. In this review, we discuss the role of TC-derived exosomes in tumorigenesis and development, and describe the application of exosomes in the diagnosis and treatment of TC.

The focus of present research endeavor was to design a robust fractional-order proportional-integral-derivative (FOPID) controller with specified phase margin (PM) and gain cross over frequency (ωgc) through the reduced-order model for continuous interval systems. Currently, this investigation is two-fold: In the first part, a modified Routh approximation technique along with the matching Markov parameters (MPs) and time moments (TMs) are utilized to derive a stable reduced-order continuous interval plant (ROCIP) for a stable high-order continuous interval plant (HOCIP). Whereas in the second part, the FOPID controller is designed for ROCIP by considering PM and ωgc as the performance criteria. The FOPID controller parameters are tuned based on the frequency domain specifications using an advanced sine-cosine algorithm (SCA). SCA algorithm is used due to being simple in implementation and effective in performance. The proposed SCA-based FOPID controller is found to be robust and efficient. Thus, the designed FOPID controller is applied to HOCIP. The proposed controller design technique is elaborated by considering a single-input-single-output (SISO) test case. Validity and efficacy of the proposed technique is established based on the simulation results obtained. In addition, the designed FOPID controller retains the desired PM and ωgc when implemented on HOCIP. Further, the results proved the eminence of the proposed technique by showing that the designed controller is working effectively for ROCIP and HOCIP.

Organic farmers farming on arable land have often had, in addition to the cultivation of common species of cultivated crops (such as wheat, rye, triticale or potatoes), interest in the cultivation of marginal crops such as hulled wheat species (Einkorn, Emmer and Spelt wheat). The production of marginal cereals has seen significant developments in the European Union related to the development of the organic farming sector. Just the average annual organic production of spelt in the Czech Republic reached more than 9000 tons in 2018. The cultivation of these cereals requires post-harvest treatment in the special method of dehulling. The waste emerging after dehulling of spikelet (i.e., chaff) accounts for about 30% of the total amount of harvest and can be used as an alternative fuel material. When considering the energy utilization of this waste, it is also necessary to obtain information on the energy quality of the material, as well as environmental aspects linked to their life cycle. For evaluating the energy parameters, the higher and lower heating value, based on the elemental (CHNS) analysis, was determined. The environmental aspects were determinate according to the Life Cycle Assessment (LCA) methodology where the system boundary includes all the processes from cradle to farm gate, and the mass unit was chosen. The SimaPro v9.1.0.11 software and ReCiPe Midpoint (H) within the characterization model was used for the data expression. The results predict the energy potential of chaff about 50–90 TJ per year. The results of this study show that in some selected impact categories, 1 kg of chaff, as a potential fuel, represents a higher load on the environment than 1 kg of lignite, respectively potential energy gain (1 GJ) from the materials.

Published: December 2020

African countries such as Nigeria are anticipated to be more susceptible to the impacts of climate change due to reliance on rainfed agriculture. In this regard, the impacts of climate change on crop water requirements (CWR), yields and crop water productivity (CWP) of soybean in the Ogun-Ona River Basin, Nigeria, were evaluated for the baseline period (1986–2015) and future period (2021–2099) under Representative Concentration Pathway (RCP) 4.5 and 8.5 scenarios using AquaCrop Version 6.1. Future climate projections from the Swedish Meteorological and Hydrological Institute’s climate models (HadGEM2-ES and RCA4) were used in simulating the future scenarios. The results show that for the baseline period, CWR and yield are increasing while CWP shows a slight increase. For the future period, the CWR is projected to fluctuate and depend on the rainfall pattern. Meanwhile, carbon dioxide fertilization has positive effects on yield and is projected to increase up to 40% under RCP 8.5. The results of this study certainly offer useful information on suitable adaption measures which could be implemented by stakeholders and policymakers to improve soybean productivity in Nigeria.
