Enlightenment, Neoliberalism, and Information Literacy
Authors: Seale Maura
Published: January 2019

This essay focuses on the ways in which ideas popularly associated with the Enlightenment function as common sense in the Framework for Information Literacy for Higher Education, which was formally approved by the Association of College and Research Libraries at the beginning of 2015. This essay begins with a close reading of the Framework for Information Literacy, followed by an analysis of its ideological underpinnings, specifically liberalism. I then use postcolonial and political theory to think through the role of historical difference in pedagogy generally and in the information literacy pedagogy articulated by the Framework more specifically. The hegemonic ideological liberalism of the Framework, its universality, narrative of progress, and disinterest in power, must be supplemented with historical difference in order to provide context for its truth claims and to inculcate responsibility to the other. This work could take the form of kairotic information literacy pedagogy, or local and contextual articulations of the Framework, or something else. The Framework is not worthless or useless, but it is also not the answer.
Seeing the Forest for the Trees on Mars: Locating the Ideology of the “Library of the Future”
Authors: Dudley Michael
Published: January 2019

For many decades now library practitioners have been generating a vast literature concerned with the “library of the future.” While much of this literature may be classified according to its imperatives for radical versus incremental change, what is largely absent from these articles is a theoretical understanding of the underlying ideological bases of their arguments, as well as extrinsic or transdisciplinary perspectives. Reconsidering these prescriptions for the future of the library through the lens of futures studies has the potential to afford us critical perspectives on their ideological foundations. Hal Niedzviecki’s 2015 book Trees on Mars: Our Obsession with the Future is analyzed to locate the ideological tensions in LIS literature between chasing the future on the one hand and cherishing the security of tradition on the other.
Consultants in Academic Libraries: Challenging, Renewing, and Extending the Dialogue
Authors: Harrington Marni R. , Dymarz Ania
Published: January 2019

There is a trend in academic libraries to hire consultants for internal crises, change management projects, strategic planning processes, outcomes assessment, evidence-based decision making, information literacy instruction, and more. Although we hear informally about the use of consultants in academic libraries, the practice has gone unexamined. We employ a historical and linguistic analysis of consultants in academic libraries, using a critical framework for this research. A critical perspective provides a structure to discuss issues that librarians may not have been able to previously fit into library practice dialogue. A chronological history of consulting in libraries acts as our literature review. This review, along with a targeted examination of library and information science resources, is used to guide two lines of linguistic analysis. The first provides a critique of the core tenets used to define and characterize library consultants, namely, the claim that consultants are unbiased professionals who bring “expertise” and “fresh” ideas to libraries. The second analysis investigates the rhetorical strategies used in existing texts: polarizing language, straw man reasoning, and figurative and indirect language. The discussion section unpacks these linguistic strategies, reflects on what is missing from the texts, and considers how knowledge and power are exerted through language, making connections to the broader context of neoliberalism.

Este trabajo de investigación se enfoca, en el plan de reducción de pérdidas de energía de la Corporación Nacional de Electricidad CNEL, de la provincia de Santo Domingo de los Tsáchilas promoviendo una campaña de concientización ciudadana para evitar el hurto de este servicio.

Durante el periodo de abril (Domingo, 2012) se indagó en los sectores de los barrios bajos de Santo Domingo el problema el cual tiene la otra cara de la moneda, pues existen innumerables asentamientos que carecen de servicios básicos como el de la energía eléctrica. En estas zonas los abonados se conectan directamente de la red para tomar energía eléctrica, sin que este problema existente desde hace años haya podido ser atenuado con eficiencia y difícilmente podrían ser eliminadas por completo.

Así se detecta un problema de incremento de las pérdidas de energía en la corporación Nacional de electricidad CNEL Santo Domingo debido a la falta de equipos de medición, equipos obsoletos o en mal estado, así como redes desnudas que dan pasó a las conexiones directas.

El plan propuesto para la recuperación de las pérdidas no técnicas del sistema CNEL Santo Domingo estima reducir las pérdidas en un lapso no superior a un año, para así lograr incrementar el flujo de caja que proporcione sustentabilidad financiera y permita el pago de los valores facturados por generadores y transmisor, así como lograr su objetivo principal: Disminuir las pérdidas que se han venido dando durante años, para lo cual se deberá emplear personal técnico capacitado y los materiales que cumplan con las normas de calidad especificadas.

Por tal virtud se recomienda una actualización permanente de su base de datos, con el fin de disponer de información precisa y confiable para el análisis de pérdida en el sistema de comercialización, para de esta forma concientizar al cliente con el fin de optimizar el uso de energía eléctrica y con esto eliminar el fraude mediante la aplicación de todos los mecanismos necesarios.

Authors: Habibullah Tarafder , Das Debasish , Paul Deb Prasad
Published: January 2019

Background: During last 2−3 decades image-guided drainage procedures have been developed complementing modern surgical drainage techniques. The development of interventional radiological procedure has made percutaneous puncture and drainage of abdominal fluid collection possible. Image-guided percutaneous drainage of appendicular abscess has become well-established because of its proven safety and efficacy.

Objectives: To evaluate the safety and feasibility of USG-guided percutaneous aspiration for draining appendicular abscess with special attention to the need for conversion and to see the nature of complications after draining of abscess.

Materials and Methods: Between May 2013 to May 2014, 25 cases of appendicular abscess were selected from the admitted patients (surgery department) in Enam Medical College & Hospital who underwent USG-guided percutaneous aspiration. Procedure was performed mostly under local anaesthesia. Patients were followed up for 6 months. Interval appendicectomy was not performed routinely.

Results: USG-guided aspiration was successful in 23 (92%) patients and in 2 (8%) patients procedure failed. Single attempt was successful in 21 (84%) cases and 4 (16%) patients needed double attempt for draining appendicular abscess. In 23 (92%) patients, PCA was done under local anaesthesia and two (8%) patients needed general anaesthesia. Complications developed in 4 (16%) patients. Four (16%) patients needed follow-up USG. Average hospital stay was 5 days (2−8 days) and average duration of using I/V antibiotic was 3.5 days (2−5 days).

Conclusion: USG-guided percutaneous aspiration is an easy and safe method for draining appendicular abscess with minimum procedural complications.

Published: January 2019

Odontomas are benign tumours of odontogenic origin consisting of different dental tissues. Usually they are tooth size or smaller, but occasionally complex variety can exhibit considerable growth. They are usually asymptomatic and often are discovered during routine radiograph. Morphologically odontoma can be classified as complex when present as irregular masses containing different types of dental tissues, or as compound if there is superficial anatomic similarity to even rudimentary teeth known as denticles. We report a case of large complex odontoma that causes pain, infection and facial asymmetry.

Authors: Abdelsalam Asmaa , Chowdhury Kamal , Bakry Ahmed El
Published: January 2019

Cymbopogon schoenanthus subsp. proximus is a medicinal grass, the source of sesquiterpene proximadiol and is well known in folk medicine as renal antispasmodic. The effect of growth regulators, different sugar types, methyl jasmonate and vitamins on de novo organogenesis from seed cultures was studied. Among different concentrations of NAA and BA, 4 mg/l NAA in combination with 0.5 mg/l BA produced 100% callus induction. Both 1.0 and 4.0 mg/l NAA in combination with 0.5 mg/l BA yielded the highest number of shoots. High concentration of sucrose 6% was efficient in root induction from organogenic shoots. Sugar types at a constant concentration of 3% had a significant effect on raising shoot numbers. Different concentrations of methyl jasmonate, biotin and Ca-pantothenate showed a decline in de novo shoot induction, but root formation frequency and numbers were significantly improved with all concentrations used.

Authors: Mamun AA , Islam MM , Ahmed M , Ghosh GC
Published: January 2019

An experiment was carried out to optimize the doses and combinations of growth regulators for in vitro propagation of Dendrobium Red Bull through shoot tip culture. The experiment was laid out according to completely randomized design with 15 treatments and three replications. For multiple shoot induction, newly grown shoot buds (keikies) were cultured on MS supplemented with various combinations of NAA and BAP. The regenerated plants were transferred to ex vitro in different substrates and acclimatized. Best response for the shoot length (21.19 mm) was obtained from the medium supplemented with 3.0 mg/l BAP with 1.5 mg/l NAA. Similarly maximum number of leaves was observed from the same combination at all the recorded days except 60 days, whereas the maximum shoot number (7.66) was obtained from the medium containing 3.0 mg/l BAP + 1.0 mg/l NAA. The shoots were then transferred to root inducing medium and well rooted plants were transferred to different substrates. Survivability of the regenerated plants varied from 60 to 92%. The substrate containing cocodust showed maximum survivability (92%) whereas minimum (60%) was observed from the substrate containing course sand. BAP and NAA proved to be good growth regulators for in vitro multiplication of Dendrobium.

Indirect in vitro Regeneration of Viola canescens Wall. ex, Roxb. by using Leaf Calli
Authors: Khajuria Arun Kumar , Bisht NS
Published: January 2019

An efficient indirect plant regeneration protocol was developed for Viola canescens, an important medicinal herb used in broad spectra of diseases in number of folk medicines since aeon. Excessive use of this plant without any rehabilitating measure has led to decline its natural population. Present investigation reports the use of zeatin to regenerate the plant from the callus on MS following its acclimatization on the soil condition. Calli of the plant responded positively to zeatin and maximum number of shoots 13.07 ± 2.01 were obtained when 9.12 μM concentration of zeatin was used. Regenerated shoots were subsequently rooted with IBA on MS and half strength MS and showed maximum number of roots 14.13 ± 1.64 after 60 days when medium was fortified with 4.92 μM IBA, followed by transferring them to soil condition, acclimatization of the plantlet was carried in growth chamber and then finally to the field for their survival where it showed 80% survival.

Published: January 2019

Assay of flavonoids in extracts of seven Thymus L. (Lamiaceae) species from Macedonia including identification and quantification was performed. Extracts obtained after hydrolysis of air dried samples (A1) were analyzed by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC). Luteolin and apigenin were identified in comparison to authentic standard substances. The content of total flavonoids in plant samples determined by UV-Vis spectrometry (with AlCl3) ranged from 0.05-0.13 %. Two other extracts were prepared by extraction with a mixture of ethanol:water (7:3, V/V), evaporation until only water remained and extraction first with diethylether (A2) and secondly with ethyl acetate (A3). The content of flavonoids in diethyl-ether and ethyl acetate extracts ranged from 52.5-244.4 mg·ml-1 and 48.7 -117.5 mg·ml-1, respectively. For quantification of luteolin and total flavonoids the HPLC method was applied, using reverse phase column C18, mobile phase consisting of 5% acetic acid and methanol in gradient elution mode and column temperature set to 40 o C. The content of luteolin in the plant samples ranged from 0.23-0.48 % (m/m), while the content of total flavonoids was found to be 0.26-0.52 %.

Published: January 2019

The effect of the buffer system on the stability of tetracaine hydrochloride in eyedrop formulation was evaluated. Eyedrop formulations containing tetracaine hydrochloride 0.5%(w/v) were prepared using different buffer systems (acetate, phosphate and borate buffer) under a constant pH of 5.4, and a buffer concentration of 0.06M. Long-term tests at 26 o C and accelerated stability tests at elevated temperature (45, 50, 60 o C) over a period of 168 days were carried out by following the macroscopic view, pH, sterility, content of tetracaine hydrochloride and detection of the degradation products. Also, values of the constant of degradation rate at different temperatures and t90% were calculated. The phosphate and acetate buffers provided satisfactory stability of tetracaine hydrochloride eyedrops, while borate buffer was not sufficient to maintain the pH value of the solution.

Published: January 2019

Certain variations in the process parameters (emulsification time, surfactant concentration) were performed in order to prepare BSA-loaded gelatin microspheres with particle size ranging from 1 to 10 µm and high loading efficiency using a procedure originally employed by Tabata and Ikada. In vitro degradation and drug release studies in the presence of trypsin and collagenase, respectively, were performed in order to evaluate the potential of gelatin microspheres as regulated and sustained release systems for oral vaccination. Degradation data showed that the preparation procedure had provided prolonged degradation in the presence of both enzymes, suggesting complete in vivo degradation. Exponential dependence of the amount of drug released on time was evidenced. The diffusion coefficients were superior to 0.5 indicating the Case II anomalous Fickian diffusion, except for the particles smaller than 5 µm where in the presence of collagenase the transition to Super Case II transport was observed due to the higher rate of polymer degradation and BSA diffusion through the matrix. The mathematical modeling of drug release showed a biphasic release pattern in the presence of both enzymes, where the rate constants for the initial time release confirmed the influence of the particle size and/or enzymatic degradation rate on the drug release rate.
Design, synthesis and determination of physical and chemical characteristics of glycoconjugates as model for oligosaccharide vaccines against vibrio cholerae
Authors: Grozdanova Aleksandra , Poceva Ana , Milenkova Katerina , Suturkova Ljubica
Published: January 2019

Cholera is toxin-mediated enteroinfection, with epidemic character and there are approximately 120000 death cases per year worldwide. Protection against cholera has not been accomplished due to deficiencies in the licensed vaccines. Serum vibriocidal activity mediated by LPS antibodies is the only immune segment correlated with the resistance of cholera. On the basis of literature data (Robbins JB, 1990; Ogawa Y, 1996) we synthesized glucoconjugates, composed of detoxified LPS from Vibrio cholerae and protein carriers. Conjugate vaccines were prepared by binding acetic acid and hydrazine-treated lipopolysaccharide (LPS) from Vibrio cholerae O1, serotype Inaba, to cholera toxin B-subunit (CT-B) and bovine serum albumin (cBSA). Adipic acid dihydrazide was used for derivatization of oligosaccharides and 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) as conjugating agent. SDS-PAGE, glycoprotein detection and TLC dot-blot were used for physical and chemical analysis of the prepared four types of conjugates. Safe level of endotoxins, measured by LAL assay was detected in all conjugates. The synthesized conjugates can be used for monitoring immunization schemes on experimental animals. It is to be expected that conjugated vaccines are safe and efficient and that will have high immunogenic and T-dependant characteristics with long immune protection against cholera.
Effect of cyclosporine therapy in transplanted patients-diagnostic values of tubular markers
Authors: Gruev Todor , Petrushevska-Tozi Lidija , Chakalarovski Koco , Ivanovski Ninonslav
Published: January 2019

The introduction of cyclosporine A (CsA) into the clinical practice has resulted in a major improvement in the short-term outcomes of solid organ transplantation and treatment of autoimune diseases. Chronic ScA nephrotoxicity has been described in kidneys of recepients of renal and other organ allografts. However, the exact mechanism underlying the development of fibrosis in chronic CsA nephrotoxicity has remained poorly understood. Evaluation with the validation data set showed that noninvasive urine protein differentiation might be a useful diagnostic strategy in nephrology. Over the past decade numerous studies in patients after transplantation have demonstrated that renal tubular cell injury after a toxic insult, results in sloughing of tubular debris and cell into the tubular lumen with eventual obstruction of tubular flow, increased intratubular pressure and backleak of glomerular filtrate out of the tubule. Urinary enzymes and low molecular proteins have been recommended as useful markers for the detection of changes in the kidney tissue in cases after renal transplantation. The aim of our study was to monitor the concentration and eventual nephrotoxic effect of Cyclosporine A using the concentration of low molecular proteins α-1-microglobulin and β−2-microglobulin, serum Cystatin C, as well as the concentration of isoform of GST-α and π.

Published: January 2019

Rapid urbanization and concretization are the main sources of formation and existence of Urban Heat Island (UHI). Due to high concentration of pollutants in urban environments, the residents are exposed to unexpected health issues. This study aims at delineating the temporal variations in the spatial extent of UHI over Gujranwala using Landsat thermal imagery. It also aims at determining the variations in pollutant concentration in the atmosphere due to vehicle’s tailpipe emissions and fossil fuel burning by industrial plants. We used various indices e.g., NDVI, NDBI, NDWI and land surface temperature calculations to investigate spatio-temporal variations in urban growth patterns and their impacts on the UHI. The results show that the UHI enlarged in all direction specially in the north west during the study period which is similar to urban growth trends. There also exist positive correlation between industrial and vehicle’s discharge with pollutant’s concentration in atmosphere. Remote sensing tools proved elegant in trend mapping and analysis.

Published: January 2019

Autisme merupakan disabilitas perkembangan yang dialami sepanjang hidup penderita Autistic Spectrum Disorder (ASD). Semakin cepat ditangani, semakin besar kemungkinan anak akan kembali normal. Untuk alasan ini, diperlukan metode baru yang dapat membantu orang tua dengan cepat mengenali gejala autisme pada anak-anak mereka. Dalam studi sebelumnya yang dilakukan oleh Fadi Fayez Tabhtah, suatu data set dihasilkan untuk mendeteksi apakah seorang anak memiliki autisme atau tidak. Tetapi penelitiannya hanya menghasilkan data set, ia tidak memeriksa lebih lanjut dimana algoritma cocok untuk data set yang telah dihasilkan. Atribut data set ternyata memiliki nilai yang salah, yang mengundang pertanyaan tentang keakurasian data. Dalam penelitian ini peneliti menggunakan metode CRISP-DM dan menguji keakuratan data set penelitian sebelumnya menggunakan algoritma C.45. Selanjutnya, aplikasi WEKA menggunakan pemilihan fitur dan pengaruh dari nilai yang salah untuk setiap atribut dan menemukan atribut yang paling signifikan. Atribut-atribut ini kemudian diuji dengan algoritma C.45 sehingga model prediksi dari data set diperoleh. Atribut A6 dari perhitungan pohon keputusan tidak muncul sama sekali sebagai cabang. Sebuah model baru diperoleh di mana atribut A6 dihilangkan, sehingga ketika diukur oleh algoritma C.45, nilai akurasi yang lebih baik diperoleh. Hasil model baru kemudian diuji pada data kuesioner baru, yang menghasilkan prediksi yang tepat.

Published: January 2019

Kebutuhan akan teknologi untuk mengatasi berbagai masalah secara cepat dan tepat semakin berkembang, khususnya untuk sistem informasi manajemen sumber daya manusia (SDM). Kegiatan pencatatan data karyawan secara manual sangat menyita waktu dan tenaga sehingga tidak efisien dan mengakibatkan persentase kesalahan data menjadi cukup tinggi. Dengan teknologi informasi diharapkan data perusahaan khususnya data karyawan dapat diolah dengan cepat dan data yang disajikan akan lebih rapi, sehingga persentase kesalahannya juga berkurang. Objek penelitian ini adalah PT. Klik Teknologi Indonesia, dimana manajemen SDM di perusahaan ini belum ditunjang oleh teknologi sistem informasi. Pengelolaan cuti dan reimburse masih dikelola secara manual. Masalah lain yang terjadi adalah tentang absensi karyawan yang bekerja secara remote, dimana belum ada sistem untuk menangani hal tersebut, sehingga menyulitkan pengelolaan data absensi dari karyawan-karyawan tersebut. Hal tersebut menjadi dasar penelitian dan pengembangan sistem informasi manajemen SDM berbasis web yang dibuat dengan metode Unified Modeling Language (UML) dengan model waterfall, sedangkan Bahasa pemrograman yang digunakan adalah Ruby, dengan framework Ruby on Rails dan basis data PostgreSQL. Dari pengimplentasian sistem dapat disimpulkan bahwa sistem informasi manajemen SDM membuat pengelolaan SDM di perusahaan menjadi lebih mudah, cepat dan akurat, selain itu sistem yang dibuat memberikan fasilitas untuk melakukan virtual absen secara real time, sehingga data dapat dikelola oleh bagian SDM.
Application of the Kano Model for a Better Understanding of Customer Requirements in Higher Education—A Pilot Study
Authors: Madzík Peter , Budaj Pavol , Mikuláš Dalibor , Zimon Dominik
Published: January 2019

Various pieces of information and knowledge turn into “know-how” simply by their application in the market. This applies to all spheres of activities. It is therefore important to know and understand the requirements of customers already in the stage of making a product, and to confront these with the possibilities of a producer. In this article we are exploring the possibilities of a better understanding of the requirements of customers and stakeholders in the process of the creation of products in educational services. In particular, we examined seven general requirements: practice orientation, ethical orientation, research orientation, quality resources, innovation orientation, skills orientation, and quality staff. We use the Kano model on a pilot sample of respondents at an institution of higher education. Our results showed that “practice orientation” and “quality resources” are the most stable requirements, while “quality staff” is the least stable. The most linear requirement (the same effect on satisfaction and dissatisfaction) is “innovation orientation”. “Research orientation” belongs to attractive requirements and we also found that in the case of “ethical orientation” there are weak relations between positive and negative responses in our survey. The “skills orientation” proved to be too general, and our research shows that it could be indifferent. It is therefore advisable to specify the investigated skills when investigating requirements on educational services. The main contribution based on the proposed research procedures is an effective linking of customers and producers already from the beginning of constructing a value chain. Investing in sophisticated management approaches when modelling products and processes can thus become a significant source of the competitive advantage of an educational institution. At the same time, it is a contribution to better placing of its graduates in the labor market.

Published: January 2019

This study was conducted to examine associations between nutrition, time of year and season of calving on milk mineral concentrations in 24 pasture-based dairy farms. There was substantial variation in the concentrations (mean with range in parentheses) of Ca 1072 (864–1310) mg/kg; citrate 1579 (880–2080) mg/kg; P 885 (640–1040) mg/kg; Mg 98 (73–122) mg/kg; Na 347 (248–554) mg/kg; K 1534 (1250–2010) mg/kg; and S 295 (155–372) mg/kg with most of the variation associated with stage of lactation, although the influence of days in milk was different for different minerals. Feeding practices were also important in determining the concentrations of some components. Milk Ca, citrate, P, and K concentrations were greater (p < 0.05) in cows receiving mineral supplements, while Ca, P and Mg were positively correlated (p < 0.05) with the amount of concentrates fed. Milk citrate and K concentrations were positively correlated (p < 0.05) with herbage allowance. Milk Se (15 (<3–37) µg/kg) and Zn (3.4 (2.2–4.9) mg/kg) also varied with time of year, with Se concentrations also greater (13.7 vs 11.6 µg/kg) in spring compared with autumn calving herds and positively correlated (p < 0.05) with the amount of concentrates fed and mineral supplementation. These data indicate that calving pattern and feeding practices could be used to reduce variation in the measured milk mineral concentrations.

A field experiment was conducted in Southern Italy to study the response of durum wheat (Triticum turgidum L. var. durum) grain yield and quality traits to a no-tillage (NT) system and different nitrogen N fertilizer rates (30, 60, and 90 kg N ha−1). The NT system was evaluated and compared to conventional (CT) and reduced (RT) tillage within continuous wheat (WW) and faba bean–wheat (FW) crop sequences over 3-years (2010–2012). The results showed a promising grain yield increase (30%) in the last year. The effect of the N rate on protein content was significant, while productive parameters were not significantly influenced due to both weather conditions and the previous crop. Tillage effect was significantly (p ≤ 0.05) positive on grain yield, yield components and quality parameters, especially in NT system, and was more pronounced when accompanied with faba bean in the rotation system. Despite producing a lower grain protein content (13%) compared to other systems, NT produced good semolina quality (with higher hectoliter weight and lower percentage of broken and shriveled grains). This study provides useful information for farmers on how to produce a satisfactory yield and good grain quality with minimum inputs, helping to design sustainable strategies for durum wheat cultivation in the dry regions.

In pea (Pisum sativum L.) production, Didymella pinodes (Berk. & A. Bloxam) Petr. is the most damaging aerial pathogen globally. In two completely randomized pot experiments with four replicates, we studied the effects of D. pinodes infection interaction with three symbiotic treatments (Rhizobium leguminosarum biovar viciae, arbuscular mycorrhizal fungi (AMF) and co-inoculation of both) and a non-symbiotic control on one or two pea cultivars. Grain yield and yield components of pea, uptakes and physiological efficiencies of N and P and nitrogen fixation were recorded. The results show that there were significant interaction effects among treatments. Therefore, productivity of crops and their uptakes and efficiencies of N and P are dependent on plant health conditions, effectiveness of microbial symbionts and response of pea genotypes. For cv. Protecta inoculated with both symbionts, pathogen infection compared to healthy plants significantly enhanced P acquisition. Overall, plants inoculated with rhizobia alone had higher grain yield by 20–30% and nitrogen fixation by 20–25% than in dual symbiosis independent of plant health conditions. In conclusion, aerial pathogen, pea genotypes and microbial symbionts interactions modified N and P uptake and their efficiencies, which can lead to improving final grain yield quantity and quality in a sustainable farming system.

An early and precise yield estimation in intensive managed grassland is mandatory for economic management decisions. RGB (red, green, blue) cameras attached on an unmanned aerial vehicle (UAV) represent a promising non-destructive technology for the assessment of crop traits especially in large and remote areas. Photogrammetric structure from motion (SfM) processing of the UAV-based images into point clouds can be used to generate 3D spatial information about the canopy height (CH). The aim of this study was the development of prediction models for dry matter yield (DMY) in temperate grassland based on CH data generated by UAV RGB imaging over a whole growing season including four cuts. The multi-temporal study compared the remote sensing technique with two conventional methods, i.e., destructive biomass sampling and ruler height measurements in two legume-grass mixtures with red clover (Trifolium pratense L.) and lucerne (Medicago sativa L.) in combination with Italian ryegrass (Lolium multiflorum Lam.). To cover the full range of legume contribution occurring in a practical grassland, pure stands of legumes and grasses contained in each mixture were also investigated. The results showed, that yield prediction by SfM-based UAV RGB imaging provided similar accuracies across all treatments (R2 = 0.59–0.81) as the ruler height measurements (R2 = 0.58–0.78). Furthermore, results of yield prediction by UAV RGB imaging demonstrated an improved robustness when an increased CH variability occurred due to extreme weather conditions. It became apparent that morphological characteristics of clover-based canopies (R2 = 0.75) allow a better remotely sensed prediction of total annual yield than for lucerne-grass mixtures (R2 = 0.64), and that these crop-specific models cannot be easily transferred to other grassland types.

Sesame is an important oilseed crop cultivated worldwide. However, research has focused on biochar effects on grain crops and vegetable and there is still a scarcity of information of biochar addition on sesame. This study was to assess the effect of biochar addition on sesame performance, with a specific emphasis on growth, yield, leaf nutrient concentration, seed mineral nutrients, and soil physicochemical properties. A field experiment was conducted on an upland field converted from paddy at Tottori Prefecture, Japan. Rice husk biochar was added to sesame cropping at rates of 0 (F), 20 (F+20B), 50 (F+50B) and 100 (F+100B) t ha−1 and combined with NPK fertilization in a first cropping and a second cropping field in 2017. Biochar addition increased plant height, yield and the total number of seeds per plant more in the first cropping than in the second cropping. The F+50B significantly increased seed yield by 35.0% in the first cropping whereas the F+20B non-significantly increased seed yield by 25.1% in the second cropping. At increasing biochar rates, plant K significantly increased while decreasing Mg whereas N and crude protein, P and Ca were non-significantly higher compared to the control. Soil porosity and bulk density improved with biochar addition while pH, exchangeable K, total N, C/N ratio and CEC significantly increased with biochar, but the effect faded in the second cropping. Conversely exchangeable Mg and its plant tissue concentration decreased due to competitive ion effect of high K from the biochar. Biochar addition is effective for increasing nutrient availability especially K for sesame while improving soil physicochemical properties to increase seed yield, growth and seed mineral quality.

Hull opening is a key physiological process during reproductive development, strongly affecting the subsequent fertilization and seed development in rice. In this study, we characterized a rice mutant, non-open hull 1 (noh1), which was derived from ethylmethane-sulfonate (EMS)-treated Xinong 1B (Oryza sativa L.). All the spikelets of noh1 developed elongated and thin lodicules, which caused the failure of hull opening and the cleistogamy. In some spikelets of the noh1, sterile lemmas transformed into hull-like organs. qPCR analysis indicated that the expression of A- and E-function genes was significantly upregulated, while the expression of some B-function genes was downregulated in the lodicules of noh1. In addition, the expression of A-function genes was significantly upregulated, while the expression of some sterile-lemma maker genes was downregulated in the sterile lemma of noh1. These data suggested that the lodicule and sterile lemma in noh1 mutant gained glume-like and lemma-like identity, respectively. Genetic analysis showed that the noh1 trait was controlled by a single recessive gene. The NOH1 gene was mapped between the molecular markers ZJ-9 and ZJ-25 on chromosome 1 with a physical region of 60 kb, which contained nine annotated genes. These results provide a foundation for the cloning and functional research of NOH1 gene.

Recent studies on using soil enhancer material, such as biochar, provide varying results from a soil hydrological and chemical perspective. Therefore, research focusing on soil-biochar-plant interactions is still necessary to enhance our knowledge on complex effects of biochar on soil characteristics. The present study investigated the changes in soil water content (SWC) and soil respiration (belowground CO2 production) over time during the growth of Capsicum annuum (pepper) in pot experiments. Concurrently, we investigated the influence of grain husk biochar with the amount of 0, 0.5%, 2.5%, and 5.0% (by weight) added to silt loam soil. Pepper plants were grown under natural environmental conditions to better represent field conditions, and additional irrigation was applied. SWC among treatments showed minor changes to precipitation during the beginning of the study while plants were in the growing phase. The highest water holding throughout the experiment was observed in the case of BC5.0. CO2 production increased in biochar amended soils during the first few days of the experiments; while the overall cumulative CO2 production was the highest in control and the lowest in BC2.5 treatments. We used the HYDRUS 1D soil hydrological model to simulate changes in SWC, using the control treatment without biochar as a reference data source for model calibration. The simulated SWC dynamics fitted well the measured ones in all treatments. Therefore, the HYDRUS 1D can be an exceptionally valuable tool to predict the hydrological response of different amount of biochar addition to silt loam soil including plant growth.
