Produk pertanian kentang menjadi sangat penting karena termasuk makanan utama bagi manusia. Kentang memiliki kandungan karbohidrat yang menjadikanya sebagai makanan utama. Dalam mengelola pertanian kentang ini tentu memiliki beberapa kendala diantaranya adalah penyakit yang menyerang pada daun kentang yang jika dibiarkan akan menghasilkan produksi yang buruk atau bahkan gagal panen. Late blight dan early blight adalah penyakit yang sering ditemui pada daun kentang. Penyakit ini memiliki gejala masing-masing sehingga para petani dapat melakukan pencegahan jika melihat gejala pada daun kentang, tetapi langkah ini memliki kelemahan yaitu proses identifikasi yang lama, dan jika penanganan pada penyakit daun ini sangat lambat akan mengakibatkan penambahan biaya perawatan. Dengan memanfaatkan teknologi yaitu berupa pengolahan citra digital maka hal ini bisa diatasi, jadi pada penelitian ini akan mengusulkan metode yang tepat dalam mendeteksi penyakit pada daun kentang. Klasifikasi akan dilakukan dengan tiga kelas berupa daun sehat, early blight, dan late blight menggunakan metode Deep Learning mengguanakan arsitektur Convolutional Neural Network (CNN). Hasil pada peneltian ini dianggap baik karena pada epoch ke 10 dengan batch size 20 menghasilkan training akurasi 95% dan validation accuracy 94%.Kata Kunci—Penyakit daun kentang, late blight, early blight, identifikasi, CNNPotato agricultural products are essential because they are the leading food. Potatoes have carbohydrate content, which makes them the leading food for humans. But in carrying out this potato farming certainly has several obstacles, including the disease that attacks the potato leaves which if left unchecked will result in poor production or even crop failure. late blight and early blight are diseases that are often found in potato leaves. This disease has its own symptoms so that farmers can take precautions if they see symptoms on potato leaves, but this step has a weakness that is a long identification process, and if the handling of this leaf disease is very slow will result in additional maintenance costs. By utilizing technology in the form of digital image processing, this can be overcome, so this research will propose an appropriate method in detecting diseases in the leaves of potato plants. Classification will be carried out with three classes in the form of healthy leaves, early blight, and late blight using the Convolutional Neural Network (CNN) algorithm. The results of this research are considered good because on the 10th epoch with batch size 20 produces 95% accuracy training and 94% validation accuracy.Keywords—Potato leaf disease, late blight, early blight, identification, CNN

Monografie Elektronizace výuky práva shrnuje dosavadní poznatky s využíváním digitálních technologii na Fakultě právnické Západočeské univerzity v Plzni, Právnické fakultě Univerzity Karlovy a Ústavu státu a práva AV ČR. Ačkoliv všichni autoři podporují digitalizací výuky, jejich názory na její provedení se různí, což považujeme za pozitivní. Podobně je tomu i u studentů, jak ukazují výsledky průzkumu prováděného kolegy z pražské právnické fakulty. Digitalizace je sice nezvratný a v zásadě pozitivní proces, který ovšem současně přináší do výuky tak zásadní změny, že zatím se s nimi obtížně vyrovnávají jak studenti, tak učitelé. Autoři upozorňují i na negativní trendy, které zejména s povrchní digitalizací souvisí. Společné mínění autorů vychází z teze, že digitalizovat má smysl tam, kde digitalizace skutečně zvýší kvalitu výuky práva.
Healthy Cities South Auckland: A focus on youth leadership and sustainability in the post-COVID world
Authors: Conn Cath , Field Robert , Hinepo Williams Margaret , Cammock Radilaite , Nnabugwu Adetoun
Published: April 2021

Introduction: This paper draws on a presentation given at the American Public Health Association (APHA) annual meeting in Philadelphia in 2019 (Drs. Conn and Field). It is based on an innovative public health initiative in the Aotearoa New Zealand context, which incorporates key themes relating to sustainable and healthy cities in the post-COVID world.

Method: Healthy cities South Auckland began in 2019, and involves Auckland University of Technology (AUT) faculty and students, many of whom are from indigenous Māori and Pacific Island communities, working collaboratively. The initiative aims to improve the health and wellbeing of the urban population using a series of codesigned projects that prioritise youth leadership and principles of sustainability. Current projects include an investigation of healthy food youth enterprise and the role of urban sustainable food environments; and student, faculty, and industry codesign of future-oriented public health higher education.

Discussion: Whilst this public health initiative is grounded in known principles of community action and determinants of health, it is innovative in the close and contextualised attention to Māori and Pacific youth leadership and to a more overt sustainability agenda. Emphasising the shift from healthy cities focusing on people, to one that focuses on the inextricable link between people and the natural environment, the initiative is underpinned by indigenous guardianship concepts, such as Māori Kaitiakitanga (guardianship of the natural order) and Pacific Va (healthy spaces). Traditionally associated with rural and marine spaces, a valuable new development is the application of indigenous principles by youth in an urban setting and for a public health agenda. These notions resonate with global shifts such as the ‘school strikes for climate change’ movement and seem particularly apt in a post-COVID world which must mobilise new ways of bringing about transformative change. These include addressing disease outbreaksand chronic disease and health inequities, while also taking into consideration the contexts of community, culture and natural environments.

Conclusion: In the Aotearoa New Zealand context, strengths-based approaches are a vital way forward, positioning Māori and Pacific young people as champions. Notions of healthy cities as sustainable cities; based on indigenous guardianship applied to 21st century urban spaces; youth activism and urban health in the digital age; and partnership between academia, youth, and industry are significant areas for further study, providing useful lessons for cities’ agendas, both locally and internationally.

Published: April 2021

This research aims to determine the effect of plasticizer types and concentrations on the characteristics of glucomannan bioplastics, and to determine the types and concentrations of plasticizers that can produce glucomannan bioplastics with the best characteristics. This experimental design used a completely randomized design method. Factor I is a type of plasticizer consisting of glycerol, sorbitol, propanol-2, and polyethylene glycol. The second factor is the concentration of plasticizers which consists of 4 levels, namely 0.5%: 1.5%: 2.5%: 3.5%. The experiment resulted in 16 treatment combinations and grouped into 2 groups to obtain 32 experimental units. The data were analyzed for their diversity and continued with the Duncan multiple comparison test. The results showed that the type and concentration of plasticizers had a very significant effect on tensile strength, elongation at break, modulus young, and swelling. The interaction has a very significant effect on tensile strength and expansion and has a significant effect on the elasticity of glucomannan bioplastics. Meanwhile, the type and concentration of plasticizers had no significant effect on the length of biodegradation. The best glucomannan bioplastic was obtained in the treatment of glycerol plasticizers with a concentration of 1.5 % with a tensile strength value of 6.17 MPa, elongation at break of 21.50 %, elasticity 28.72 MPa development 25.84 %, and degradation time of 8 days. Bioplastics produced in this study have meet the SNI 7188.7:2016 standards in the elongation test at break and standards ASTM 5336 in the degradation time variables. The resulting bioplastic has not met SNI on the tensile strength, modulus young, and swelling variables.

Published: April 2021

Citrate-gel auto combustion technique was used to synthesize nickel-copper mixed ferrite nanoparticles NixCu1-xFe2O4 (x= 0.0, 0.4, 1.0) with different calcinating temperatures (200, 450, 650 and 850 °C). Structural, morphological, magnetic, and electrical properties were studied using X-ray diffraction (XRD), transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FTIR), vibrating sample magnetometer (VSM), and LCR meter in order to determine significant influences of Cu2+ cations content in nickel ferrite. The XRD patterns showed that all compositions had cubic spinels, except CuFe2O4 samples. The system structure in Cu-ferrite was deformed at 650 °C  from a cubic to a tetragonal system with a secondary phase CuO. Lattice constant was decreased with increasing Cu2+ cations substitution in Ni-ferrites, while crystalline volume was increased. With the help of Debye-Scherrer`s equation using XRD data, we found that the crystallite size at 850 °C is lying in the range from 38.70  to 48.00 nm. The FTIR spectrum of samples under investigation showed two significant absorption bands, which refer to the formation of a single-phase cubic spinel. The magnetization test revealed a soft ferromagnetic behavior for all the compositions sintered at 850 °C. The saturation magnetization (Ms) was decreased with the substitution by Cu2+ cations, while remnant magnetization (Mr) and coercivity (Hc) were increased in Cu-ferrite. The highest Ms value was 42.25 emu.g-1 for Ni-ferrite, while the highest Hc value was 517.16 Oe for Cu-ferrite. The electrical measurement of samples showed an increase in the real dielectric constant and AC conductivity at a frequency range of 20Hz-3MHz with the addition of copper cations.

Authors: Hanan J. Mustafa  , Tagreed M. Al-Saadi
Published: April 2021

To study the removal of lead (Pb) ions from aqueous solutions, novel magnetite nanoparticles (NPs) of Ni0.31Mg0.15Ag0.04Fe2.5O4 were synthesized by coprecipitation synthesis using metal sulfates, and then coated with Gum Arabic (GA). The prepared NPs were analyzed using various spectroscopic and analytical methods, such as X-Ray diffraction analysis (XRD), Field Emission Scanning Electron Microscopy (FE-SEM), Energy Dispersive X-ray spectroscopy (EDX), Fourier Transform Infra-Red spectroscopy (FT-IR), and Atomic Absorption Spectrophotometer (AAS). By using XRD analysis, the cubic inverse spinel structure of the prepared NPs was proven, showing average values of crystallite size, lattice constant, and density of 28.57nm, 8.32582Å, and 5.2890 g/cm3, respectively. FE-SEM analysis revealed the sphere-like shape of the nanoparticles with a measured crystallite size of 25.93nm. The existence of constituent elements was evidenced by EDX. FT-IR test proved the success of the coating process of magnetite NPs by the presence of the main characteristic absorption bands of GA in the FT-IR spectrum of GA-magnetite NPs. The adsorption of Pb ions by GA- magnetite NPs was shown by AAS analysis, where the concentration of Pb ions decreased from 25ppm to 6.6ppm, reaching 1.1ppm at the time of 25min. The porosity of the NPs and the carboxyl groups in GA played an important role in the process.

Published: April 2021

Compressive Strength (CS) is an important mechanical feature of concrete taken as an essential factor in construction. The current study has investigated the effect of fly ash and silica fume replacement content on the strength of concrete through Artificial Neural Networks (ANNs) and Extreme Learning Machine (ELM). In this study, different ratios of fly ash with (out) extra quantity of silica fume have been tested. Water cement (w/c) ratio varies during the test. Eight input parameters including Total Cementitious Material (TCM), Silica Fume (SF) replacement ratio, coarse aggregate (ca), fly ash (FA) replacement ratio, Sewage Sludge Ash (SSA) as a combination of cement and fine aggregate replacement, water-cement ratio, High Ratio Water Reducing Agent (HRWRA) and Age of Samples (AS) and one output parameter as the CS of concrete have been investigated through ANN and ELM. Up to now, numerous experimental studies have been used to analyze the compressive strength of concrete while retrofitted with fly ash or silica fume, however, the novelty of this study is in its use of AI models (ELM, ANN). The models have been developed and their outcomes were compared through six statistical indicators (MAE, RMSE, RRMSE, WI, RMAE and R2). Subsequently, both methods were shown as reliable tools for assessing the influence of cementitious material on compressive strength of concrete, however, ANN remarkably was better than ELM. As a result, FA showed less contribution to the strength of concrete at short times, but much at later ages. As a result, the enhanced influence of low amount of SF on CS was not significant. Adding fly ash has reduced the compressive strength in short term, but increased the compressive strength in long term. Adding silica fume raises the strength in short term, but decreases the strength in long term.

Published: April 2021

The Electrical Submersible Pumping (ESP) system is one of the most commonly used artificial lift methods in the petroleum industry and one recent breakthrough in this system is enclosed in a capsule and positioned on the seabed in a skid. As it is a recent technology, with only a small amount of equipment currently in operation, there is a clear need for a greater understanding of the flow within this geometry with the objective of perfecting the design of this promising submarine boosting system. This paper presents a numerical investigation of single-phase flow within the scaled capsule-intake of an ESP system in the Skid considering a model with geometric and dynamic similarities in relation to a real equipment in operation in the Espadarte field, located in the Campos Basin, Brazil. The tridimensional and transient simulation for a case for one mass flow rate and inclination angles are investigated. While neglecting the effects of the diffuser and impeller in the system, the flow field features, axial and radial velocity profiles in the intake region were computed. The numerical results show that the flow in the intake region is dominated by the secondary flow, leading to the formation of bathtub vortex. It is expected that the vortices influence the flow pattern in the intake region, breaking the larger bubbles into smaller bubbles, making the transition from the slug flow pattern to the dispersed bubbles or bubbly pattern in which it would be more difficult to be dragged into the intake.

Two-dimensional electrically conductive metal-organic frameworks (MOFs) are candidate electrode materials for use in electric double-layer capacitor (EDLC) structure-property investigations due to their well-defined crystalline structures. Their promising capacitive performance was first illustrated by EDLCs constructed with the layered framework Ni3(HITP)2 (HITP = 2,3,6,7,10,11-hexaiminotriphenylene) and an organic electrolyte. Despite this promise, there have been few follow-up studies on the use of these frameworks in EDLCs, raising questions about the generality of the results. Here, we demonstrate the high capacitive performance of the layered framework Cu3(HHTP)2 (HHTP = 2,3,6,7,10,11-hexahydroxytriphenylene) in EDLCs with an organic electrolyte and compare its performance with Ni3(HITP)2. Cu3(HHTP)2 exhibits a specific capacitance of 110 – 114 F g–1 at low current densities of 0.04 – 0.05 A g–1 and shows modest capacitance retentions (66 %) at current densities up to 2 A g–1, mirroring the performance of Ni3(HITP)2. However, we also explore the limitations of Cu3(HHTP)2 in EDLCs, finding a limited cell voltage window of 1.3 V and only moderate capacitance retention over 30,000 cycles. This illustrates that these materials require further development to improve their EDLC performance, particularly to reach similar cycling performance levels as porous carbons. Despite this, our work underscores the utility of framework materials in EDLCs and suggests that capacitive performance is largely independent of the identity of the metal node and organic linker molecule, instead being dictated by the three-dimensional structure of the framework. These important insights will aid the design of future conductive MOFs for use in EDLCs.
Life Cycle Assessment of Direct Air Carbon Capture and Storage with Low-Carbon Energy Sources

Prospective energy scenarios usually rely on Carbon Dioxide Removal (CDR) technologies to achieve the climate goals of the Paris Agreement. CDR technologies aim at removing CO2 from the atmosphere in a permanent way. However, the implementation of CDR technologies typically comes along with unintended environmental side-effects such as land transformation or water consumption. These need to be quantified before large-scale implementation of any CDR option by means of Life Cycle Assessment (LCA). Direct Air Carbon Capture and Storage (DACCS) is considered to be among the CDR technologies closest to large-scale implementation, since first pilot and demonstration units have been installed and interactions with the environment are less complex than for biomass related CDR options. However, only very few LCA studies - with limited scope - have been conducted so far to determine the overall life-cycle environmental performance of DACCS. We provide a comprehensive LCA of different low temperature DACCS configurations - pertaining to solid sorbent-based technology - including a global and prospective analysis.
Drug-Drug-Dietary interactions in pharmacotherapy of GIT medication: A review
Authors: Akula sowjanya  , Abhisek Pal
Published: April 2021

Successful drug therapy depends on the interaction between drug-drug and drug-diet. Drug interactions are a vital reason for causing adverse drug reactions and modify one drug effect by another drug and these kinds of interactions can increase or decrease the effectiveness of the drug. Polypharmacy could be a major risk for Drug-Drug and Drug-food interactions. Food Consumption can alter the effect of drugs by interfering either with their pharmacokinetics or pharmacodynamics processes. Anti-ulcer drugs are used to treat different types of ulcer and that may interact with another drug showing undesirable effects. GIT medications interfere with another type of medication either with at the pharmacokinetic and pharmacodynamic level. The main objective of this article is to review data regarding common Drug-drug & Drug-food interactions related to GIT medications. Data was collected from Google Scholar, PubMed, and Scopus databases, and they were reviewed for publication on drug-drug & drug-food interactions related to GIT medications. This data is very helpful for pharmacists while reviewing and analyzing prescribed medication, especially in geriatrics prescriptions.

The Alkaline Diet and the Warburg Effect
Authors: Bahrami Hassan , Greiner Ted
Published: April 2021

The changing diets accompanying our modern life style have increased the content of foods that form acidic metabolic waste residues in the body. Wastes from these metabolic processes are released into the interstitial fluids and the blood, slightly changing their pH temporarily. This link may in turn have an impact on the incidence of non-communicable diseases (NCDs).

According to Warburg effect theory, an acidic cellular and circulatory environment may cause various specific health problems such as hypoxia and cancer, whereas an oxygen-rich optimum-alkaline environment could retain healthy cells. However, the mechanisms by which the diet may be influential on blood pH-related parameters and on health have remained largely unknown.

This paper begins with a detailed presentation of the concepts, issues and the existing evidence regarding alkaline and acid forming diets, and summarizes the three main mechanisms by which the diet influences the acid-base balance in the body. It then presents the findings of a small exploratory study in which one author (HB) followed diets traditionally thought to produce alkaline or acidic residues. After each diet period of one month (with a two-month wash out period), pH, oxygen saturation, and carbon dioxide partial pressure were measured for arterial and for venous blood.  

The resulting data indicated that the diets followed changed blood pH-related parameters in the expected directions according to the acid-base theory of health. Increased intake of acid-forming foods resulted in a slightly lower pH level, but a significant reduction of oxygen saturation in the blood, whereas increased consumption of alkaline forming foods maintained the high oxygen saturation in the blood that, according to Warburg effect theory, may, if maintained, reduce the incidence of NCDs. Further cross-over research of this kind is needed, utilizing large samples and testing various dietary modifications.
Which Hop Tests Can Best Identify Functional Limb Asymmetry in Patients 9-12 Months After Anterior Cruciate Ligament Reconstruction Employing a Hamstrings Tendon Autograft?
Authors: Ebert Jay R , Du Preez Luke , Furzer Bonnie , Edwards Peter , Joss Brendan
Published: April 2021

Background

Hop tests are commonly employed to evaluate functional limb symmetry after anterior cruciate ligament reconstruction (ACLR).

Purpose

To investigate the ability of eight hop tests to identify functional limb asymmetry in patients after ACLR.

Study Design

Prospective cohort.

Methods

Fifty patients were assessed 9-12 months following ACLR. Functional performance on both the operated and non-operated limb was assessed via eight hop tests, assessed in a randomised order. These included the: single (SHD), triple (THD) and triple crossover (TCHD) hop for distance, 6m timed hop (6MTH), single medial (MHD) and single lateral (LHD) hop for distance, single countermovement jump (SLCMJ) and timed speedy hop (TSHT). Differences in Limb Symmetry Indices (LSIs) across hop tests were compared, while Pearson’s correlations were undertaken to investigate the significance and strength of the association between hop test LSIs.

Results

Significant differences were observed across hop LSIs (p<0.0001). Mean LSIs for the SHD (95.0%), 6MTH (95.0%), THD (96.1%) and TCHD (95.3%) were ≥90% and significantly greater (p<0.05) than the MHD (87.3%), LHD (87.5%), SLCMJ (83.4%) and TSHT (86.5%), which were all <90%. The LSI for the SLCMJ was significantly lower (p<0.05) than all other hop tests. While significant correlations existed across the majority of hop LSIs, the strongest correlations existed between the SHD, THD and TCHD (r=0.70-0.80), and lowest correlations between the TSHT and the other hop tests (r=0.26-0.49).

Conclusions

The LHD, MHD and TSHT, as well as the SLCMJ in particular, were best able to demonstrate functional limb asymmetry in patients following ACLR. These hop measures should be incorporated into hop test batteries, if the purpose is to detect the presence of lingering functional deficits.

Examining Muscle Activity Differences During Single and Dual Vector Elastic Resistance Exercises
Authors: Bench Ryan WG , Thompson Sydney E , Cudlip Alan C , Holmes Michael WR
Published: April 2021

Background

Elastic resistance exercise is a common part of rehabilitation programs. While these exercises are highly prevalent, little information exists on how adding an additional resistance vector with a different direction from the primary vector alters muscle activity of the upper extremity.

Purpose

The purpose of this study was to examine the effects of dual vector exercises on torso and upper extremity muscle activity in comparison to traditional single vector techniques.

Study Design

Repeated measures design.

Methods

Sixteen healthy university-aged males completed four common shoulder exercises against elastic resistance (abduction, flexion, internal rotation, external rotation) while using a single or dual elastic vector at a fixed cadence and standardized elastic elongation. Surface electromyography was collected from 16 muscles of the right upper extremity. Mean, peak and integrated activity were extracted from linear enveloped and normalized data and a 2-way repeated measures ANOVA examined differences between conditions.

Results

All independent variables differentially influenced activation. Interactions between single/dual vectors and exercise type affected mean activation in 11/16 muscles, while interactions in peak activation existed in 7/16 muscles. Adding a secondary vector increased activation predominantly in flexion or abduction exercises; little changes existed when adding a second vector in internal and external rotation exercises. The dual vector exercise in abduction significantly increased mean activation in lower trapezius by 25.6 ± 8.11 %MVC and peak activation in supraspinatus by 29.4 ± 5.94 %MVC (p<0.01). Interactions between single/dual vectors and exercise type affected integrated electromyography for most muscles; the majority of these muscles had the highest integrated electromyography in the dual vector abduction condition.

Conclusion

Muscle activity often increased with a second resistance vector added; however, the magnitude was exercise-dependent. The majority of these changes existed in the flexion and abduction exercises, with little differences in the internal or external rotation exercises.

The Single Leg Squat Test: A “Top-Down” or “Bottom-Up” Functional Performance Test?
Authors: Carroll Lindsay A , Kivlan Benjamin R , Martin RobRoy L , Phelps Amy L , Carcia Christopher R
Published: April 2021

Background

Medial knee deviation (MKD) during the single leg squat test (SLST) is a common clinical finding that is often attributed to impairments of proximal muscular structures. Investigations into the relationship between MKD and the foot and ankle complex have provided conflicting results, which may impact clinicians’ interpretation of the SLST.

Purpose

The purpose of this study was to compare ankle dorsiflexion range of motion (ROM) and foot posture in subjects that perform the SLST with MKD (fail) versus without MKD (pass).

Hypothesis

There will be a difference in ankle dorsiflexion ROM and/or foot posture between healthy individuals that pass and fail the SLST for MKD.

Study Design

Cross-sectional study.

Methods

Sixty-five healthy, active volunteers (sex = 50 female, 15 male; age = 25.2 +/- 5.6 years; height = 1.7 +/- .1 m; weight = 68.5 +/- 13.5 kg) who demonstrated static balance and hip abductor strength sufficient for performance of the SLST participated in the study. Subjects were divided into pass and fail groups based on visual observation of MKD during the SLST. Foot Posture Index (FPI-6) scores and measures of non-weight bearing and weight bearing active ankle dorsiflexion (ROM) were compared.

Results

There were 33 individuals in the pass group and 32 in the fail group. The groups were similar on age (p = .899), sex (p = .341), BMI (p = .818), and Tegner Activity Scale score (p = .456). There were no statistically significant differences between the groups on the FPI-6 (pass group mean = 2.5 +/- 3.9; fail group mean = 2.3 +/- 3.5; p = .599), or any of the measures of dorsiflexion range of motion (non-weight bearing dorsiflexion with knee extended: pass group = 6.9o +/- 3.7o, fail group = 7.8o +/- 3.0o; non-weight bearing dorsiflexion with knee flexed: pass group = 13.5o +/- 5.6o, fail group = 13.9o +/- 5.3o; weight bearing dorsiflexion: pass group = 42.7o +/- 6.0o, 42.7o +/- 8.3o, p = .611).

Conclusions

Failure on the SLST is not related to differences in clinical measures of active dorsiflexion ROM or foot posture in young, healthy individuals. These findings suggest that clinicians may continue using the SLST to assess neuromuscular performance of the trunk, hip, and knee without ankle dorsiflexion ROM or foot posture contributing to results.
