VARIASI POHON FRAKTAL MENGGUNAKAN L-SYSTEMS
Authors: Ramdhan Pradifta Gilang , Purnomo Kosala D. , Ubaidillah Firdaus
Published: October 2021

Fractal tree is simply a trunk and a number of branches, each of which looks like the tree itself. The fractal tree can be generated using the IFS and L-Systems methods. In this article, the author develops fractal tree generation using L-Systems with additional variations. The variations given are in thickness, length, and branch angle. This development is expected to produce more diverse fractal tree patterns. In generating a fractal tree using L-Systems, it begins by determining the letters and symbols to be used. Then determine which axioms should be used. Then the production rules are made together with the determination of the parametric L-Systems. And the last is to determine the probability value for the stochastic L-Systems. In the deterministic L-Systems, thickness variations, length variations, and branch angle variations are carried out. In the variation of branch thickness, if the ratio of the thickness of the left branch is greater than that of the right branch, the fractal tree is skewed to the left. Then in the variation of branch length if the ratio of the length of the left branch is smaller than the ratio of the length of the right branch, the length of the left branch is longer than the length of the right branch. Then at the angle of the branching the smaller the 𝜃 that is included causes the branches to be closer together. The use of stochastic L-Systems can produce more diverse fractal tree patterns, even though they use the same production rules and parameter values

Communication in the current era of globalization is very developed. Many applications that can be used to facilitate communication. However, because of this convenience, the security of the information contained in it will be more easily hacked by irresponsible people. Cryptography is the science or art for security message. In cryptography there are two important processes, namely encryption and decryption. The sender's job is to encrypt the message and the receiver's job is to decrypt the message. The key used for this cryptographic process is the Cipher Block Chaining (CBC) operation mode. CBC mode is a very simple operation mode, so additional techniques are needed to make it more secure. The plaintext will be replaced with new plaintext resulting from a combination of Caesar Cipher and Reverse Cipher techniques. The results obtained indicate that the application of plaintext modifications to CBC can improve message security because the keys used are increasingly complex.

There are several factors that can cause problems in the land sector in Indonesia, one of which is inheritance. This study aims to determine: 1) the legal position of the heirs of foreign citizens in the object of inheritance in the form of land rights obtained from inheritance with Indonesian citizenship; and 2) The validity of the control of land rights by foreign countries on objects originating from the inheritance of Indonesian citizens. The research method uses a normative juridical approach to the law (statute approach), conceptual approach (conceptual approach), and case study approach (case study). The results of the study are heirs who have changed their status to foreign citizens can also be proven by their lineage or have blood relations so that if they acquire property in the form of land originating from inheritance while those who control the property are foreign nationals, if possible, do so to discuss the object. through an exchange, grant, or auction within a maximum period of 1 (one) year, the status will automatically switch. If the land has been turned into state land, then the owner is considered to have relinquished his rights but the owner is still given the opportunity by law to be able to apply for the Right to Use the land.Keywords: Inheritance Law; Legality Of Ownership Of Land Rights; Foreign Nationalilty.Terdapat beberapa faktor yang dapat menimbulkan permasalahan di bidang pertanahan di Indonesia, salah satunya adalah pewarisan.

Duty on the Acquisition of Land and Building Rights or BPHTB is a tax on the acquisition of rights to land and building. It is likely that in the future there will be an overpayment of BPHTB; in the case study of the Supreme Court Decision Number 1154/B/PK/PJK/2017, there was an overpayment of non-payable tax in 2009 by PT Bumi Sawit Permai to KPP Pratama Prabu Mulih which had just been filed at in 2012. There was a difference in authority in returning the BPHTB overpayment, considering that Law No. 20 of 2000, Amendment to Law Number 21 of 1997 on Duty on the Acquisition of Land and Building Rights, which classified BPHTB under Central Tax, was revoked and declared no longer valid since January 1st, 2011, replaced by Law No. 28 of 2009 on Regional Taxes and Retribution (UU PDRD) that classified it under Regional Tax. According to article 23 paragraph (1), (1a) and (2) Law Number 20 of 2000 on Amendment to Law Number 21 of 1997 on Duty on the Acquisition of Land and Building Rights, it was KPP Pratama Prabumulih’s obligation to return the overpayment of the non-payable tax.

In Article 7 paragraph (2) of Law Number 1 of 1974 concerning Marriage it is stated that in the event of a deviation from the minimal age of marriage, a marriage dispensation may be requested from the court or other official appointed by both male and female parents. However, there are no indicators related to the conditions for marriage dispensation to be proposed in Law Number 1 of 1974 making the legal politics of granting marriage dispensations focus on judges. In its development, was born Law Number 16 of 2019 replaced Law Number 1 of 1974. This article is a legal article with a statutory approach, a conceptual approach, and a case approach. Through this article, it was found that there was a political change in the marriage dispensation law in Law Number 16 Year 2019, where the politics of marriage dispensation law was stricter than Law Number 1 of 1974 and had the spirit not to easily provide marriage dispensation. This can be seen from the existence of two conditions for filing a dispensation in Law Number 16 of 2019, namely (1) having urgent reasons and (2) Having sufficient supporting evidence.Keywords: Marriage Dispensation; Marriage Law; Politics Of Law.Pasal 7 ayat (2) Undang-Undang Nomor 1 Tahun 1974 tentang Perkawinan disebutkan, bahwa dalam hal terjadi penyimpangan batas usia minimal perkawinan, maka dapat dimintakan dispensasi perkawinan kepada Pengadilan atau Pejabat lain yang ditunjuk oleh kedua orang tua pihak pria maupun pihak wanita. Namun, tidak ada indikator terkait kondisi dapat diajukannya dispensasi perkawinan di dalam Undang-Undang Nomor 1 Tahun 1974 membuat politik hukum pemberian dispensasi perkawinan, benar-benar menitikberatkan pada hakim. Dalam perkembangannya, lahir Undang-Undang Nomor 16 Tahun 2019 yang menggantikan Undang-Undang Nomor 1 Tahun 1974. Artikel ini merupakan artikel hukum dengan pendekatan peraturan perundang-Undangan (statute approach), pendekatan konseptual (conceptual approach), dan pendekatan kasus (case approach). Melalui artikel ini, ditemukan bahwa terjadi perubahan politik hukum dispensasi perkawinan di dalam Undang-Undang Nomor 16 Tahun 2019 , dimana politik hukum dispensasi perkawinan bersifat lebih ketat daripada Undang-Undang Nomor 1 Tahun 1974 dan memiliki semangat untuk tidak dengan mudah memberikan dispensasi perkawinan. Hal ini dapat terlihat dari adanya dua syarat diajukannya dispensasi di dalam Undang-Undang Nomor 16 Tahun 2019, yaitu (1) memiliki alasan mendesak dan (2) Memiliki bukti-bukti pendukung yang cukup.Kata Kunci: Dispensasi Perkawinan; Perkawinan; Politik Hukum.

International economic relations sure is very important for a country and the important thing that follows is the policy that regulates international economic relations it self. In this study, the authors will analyze hows  Renewable Energy Directive II (RED II) policy as a derivative of the RED (Renewable Energy Directive) policy by the European Union will affect the Indonesian palm oil trade which this also would show the violations of previous policies that is General Agreement on Tarifs and Trades. Authors also going to show General Agreement on Tariffs and Trade (GATT) as a policy that regulates how international trade relations should be carried out and the violations of this international agreement undoubtedly could affect Economic relations between the two countries, both on a micro scale and macro scale. In conducting the research authors will be using the normative juridical methods which means the legal research will be based off library materials and secondary materials therefore the main result from this study would be a reflection of how RED II can affect trade in indonesian palm oil products and also by effecting this regulation in 2021 the european union will be violating the non-discrimination principle in GATT 1947.
Juridical Analysis of Regulation Controling of Import or Export of Goods That are Suspected or Originating of Intellectual Property Infringment, Particularly on Registered Trademark
Authors: Basuki Liah Anggraeni
Published: October 2021

Protection of intellectual property laws can be started from the action of preventing the entry or exit of goods from a country. The Directorate General of Customs and Excise, Ministry of Finance of the Republic of Indonesia, which is the implementing agency in the customs sector, can control the import or export of goods suspected of being or originating from the result of intellectual property infringement. It is a financial activity involving several institutions including the Directorate General of Customs and Excise, the Ministry of Finance of the Republic of Indonesia as executor, the Directorate of Trademarks, the Ministry of Law and Human Rights as the institution that issues trademark rights and the Commercial District Court to exercise judicial authority. Its implementation, regulations have been made regarding the processes and conditions for controlling the export and import of goods, which accommodate the interests of the state as a regulator with the aim of regulating and harmonizing customs regulations and trademark law and the interests of rights holders or mark owners as the injured party if there is an infringement. However, there are arrangements that are "considered" to be detrimental to the right holder or registered mark owner, that is in relation to the domicile of the party applying for trademark protection in the customs area. This research uses a normative research type and a statue approach as well as a conceptual approach. So that with this research the brand owners or rights holders can determine the right steps to protect the registered marks in accordance with applicable regulations.
Powers and Limits of State during COVID-19 Pandemic: a Critical Appraisal
Authors: Satriawan Iwan , Seviyana Devi
Published: October 2021

The research aims to analyze the power and limit of the state and whether Indonesia has properly adopted the concept of powers and limits during state emergency of COVID-19 pandemic. The method of the research was normative legal research which used statute and case approach were employed for data analysis. The result shows that a state may apply some types of power in an emergency condition. However, in using its powers, the government must consider principle of limits in a state of emergency. In fact, Indonesia does not properly adopt the balance of power and limit in the state of emergency during COVID-19 pandemic. It is true that the government may take actions to respond to the COVID-19 pandemic. However, the State cannot exceed the limitations of using powers in accordance with state emergency principle. There was a tendency to exceed the limits by the State during the pandemic. The State has violated some state of emergency principles during COVID-19 pandemic such as temporary, the rule of law, necessity, proportionally, intangibility, constitutionalism, harmony, and supervision. The research recommends that the Government and the House of Representatives (the DPR) in the future should obey the state of emergency principles, particularly in terms of state power limits to respect constitutional principles and rule of law. In addition, individuals, groups of people, or organizations may submit judicial review of laws or regulations that violate the state of emergency principles in handling pandemic in the light of protecting the fundamental rights of citizens.
The Indonesian Government's Inconsistency in Handling The Covid-19 Pandemic

Published: October 2021

A clear legal umbrella is a basis for the effectiveness of a policy, including in dealing with the Covid-19 pandemic. However, the inconsistency of the legal umbrella in giving birth legal uncertain, and the public becomes confused. This research aims to critique the Indonesian government's attitude in dealing with the Covid-19 pandemic, which began in early 2020 due to the legal umbrella's inconsistency in enforcing different and ineffective legal sanctions at the central government and local governments. The research method used is normative research with a statutory approach. In contrast, the research explained in a descriptive-qualitative way. This research shows that the government considers the Covid-19 pandemic a non-natural disaster and does not lockdown. Meanwhile, the legal umbrella used is the health quarantine law, which requires implementing public health emergencies, almost the same as lockdowns. On the other hand, the Large-Scale Social Restriction (PSBB) policy has a legal basis for a health quarantine law. At the same time, the Covid-19 pandemic situation is a non-natural disaster that should refer to the disaster management law. Furthermore, other results also show ineffective enforcement of legal sanctions, such as criminal sanctions in regional head decisions that can not enforce because PSBB only includes administrative sanctions. In conclusion, the inconsistency of the legal umbrella in dealing with the Covid-19 pandemic is very detrimental to the community due to limited human rights, which can lead to legal uncertainty and public distrust of the government.

Authors: E A M. Kenza Radhya , Nurifanti Ersya Dwi
Published: October 2021

The Covid-19 pandemic brings new challenges to people around the world, including Indonesia. In Indonesia, the Covid-19 pandemic is still an unresolved problem. As a result of the Covid-19 pandemic, besides threatening health and the economy, it is also exacerbated by government policies. Conflicting policies hinder obstacles in handling the Covid-19 pandemic. The need for a solution in the form of the formation of an umbrella act to overcome the conditions caused by the covid-19 pandemic, which covers the health and economic sectors, can be a solution to the conflicts applied by the Government, and the Umbrella Act can answer the Government's confusion in overcoming this pandemic. This study uses a normative method that discusses legal aspects by critically analyzing library materials applicable to laws and regulations. Umbrella actions can go beyond conflicting with an integrated rule. The Umbrella act can be applied in Indonesia and can be a solution to overcome the number of cases of the Covid-19 pandemic, which is still relatively high. With the Umbrella Act, the Government's responsibility will be fulfilled to provide legal protection to the community. The Umbrella Act, which has been proven to overcome conflicting regulations, will solve the current emergency. With the Umbrella Act, the Government's responsibility will fulfill to provide legal protection to society.
Epidemiology: Gray Immunity Model Gives Qualitatively Different Predictions
Authors: Watve Milind , Bhisikar Himanshu , Kharate Rohini
Published: October 2021

Compartmental models like the SIR model that dynamically divide the host population in categories such as susceptible, infected and immune form the mainstream of epidemiological modelling. Effectively such models treat infection and immunity as binary variables. We show here that considering immunity as a continuous variable instead of binary and incorporating factors that bring about small changes in immunity lead to qualitatively different epidemiological predictions. The small immunity effects (SIE) constitute cross immunity by other infections, small increments in immunity by sub clinical exposures and slow decay in the absence of repeated exposure. The SIE model explains many epidemiological patterns observed during the Covid-19 pandemic that are not adequately explained by conventional models. In the SIE model repeated waves are possible without the need for new variants. Peak and decline of a wave much before reaching herd immunity threshold, low level apparently stable existence of the pathogen, new surges after variable and unpredictable gaps, new surge after vaccinating majority of population are the common features of the pandemic mimicked by simulations using the SIE model. The model further shows complex interactions of different interventions that can be contextually synergistic as well as antagonistic. As a result, interventions intended to arrest the transmission are not always effective and can turn counterproductive under some conditions. Interventions that are beneficial in the short run can be potentially hazardous in the long run. In the absence of empirical estimates of many parameters, the model may not be useful to make quantitative predictions at this stage but it certainly challenges traditional wisdom and currently held beliefs behind non-pharmaceutical interventions recommended to control the epidemic. We also suggest testable predictions to differentiate between the causal logic of the SIE model against the prevalent explanations for the same observed phenomena.

Published: October 2021

Enteric methane (CH4) emitted by ruminant species is known as one of the main greenhouse gases produced by the agricultural sector. The objective of this study was to evaluate the chemical composition, in vitro gas production, dry matter degradation (DMD), digestibility, CO2 production and CH4 mitigation potential of five tropical tree species with novel forage potential including: Spondias mombin, Acacia pennatula, Parmentiera aculeata, Brosimum alicastrum and Bursera simaruba mixed at two levels of inclusion (15 and 30%) with a tropical grass (Pennisetum purpureum). Crude protein content was similar across treatments (135 g kg-1 DM), while P. purpureum was characterized by a high content of acid detergent fiber (335.9 g kg-1 DM) and B. simaruba by a high concentration of condensed tannins (20 g kg-1 DM). Likewise, A. pennatula and P. aculeata were characterized by a high content of cyanogenic glycosides and alkaloids respectively. Treatments SM30-PP70 (30% S. mombin + 70% P. purpureum) and BA30-PP70 (30% B. alicastrum + 70% P. purpureum) resulted in superior digestibility than P. purpureum, while in the AP30-PP70 (30% A. pennatula + 70% P. purpureum) was lower than the control treatment (P≤0.05). At 24 and 48 h, treatments that contained P. aculeata and B. alicastrum produced higher CH4 ml g-1 DOM than P. purpureum (P≤0.05). The inclusion of B. simaruba at 30% reduced CH4 at 25% compared to P. purpureum. Tropical tree species can improve the nutritional quality of ruminant rations and reduce CH4 emissions to consequently contribute to the development of sustainable ruminant production systems that generate diverse ecosystem services.

Published: October 2021

The spectra of the plasma emitted from the studied samples consist of several dozens of narrow bands superimposed on each other. Tables of spectral lines were used to interpret the spectra. It turned out that the largest number of bands corresponds to the radiation of positively charged ions and atoms of elements that make up the crystal lattices of minerals that make up the studied rocks. Thus, the spectra of the plasma emitted from quartz corresponded to the radiation of atoms and positively charged silicon ions, the charge of which varied from 1 to 4, as well as atoms and positively charged oxygen ions, the charge of which varied from 1 to 3. Positively charged ions and atoms of Si, O, K, Ca, Al and Na, which are part of the crystal lattices of quartz and feldspar, flew out of granites. Positively charged ions and Ca, C and O atoms flew out of the calcite.
Assessment of Microplastic Impacts in the Marine Environment: A Review
Authors: Walker Tony
Published: October 2021

Threats emerging from microplastics pollution in the marine environment have received much global attention. This review assessed sources, fate, and impacts of microplastics in marine ecosystems and identified gaps. Most studies document ubiquity of microplastics and associated environmental effects. Effects include impacts to marine ecosystems, risks to biodiversity, and threats to human health. Microplastic leakage into marine ecosystems arises from plastic waste mismanagement and a lack of effective mitigative strategies. This review identified a scarcity of microplastics mitigation strategies across different stakeholders. Lack of community involvement in microplastic monitoring or ecosystem conservation exists due to limited existence of stakeholder co-management initiatives. Although some management strategies exist for controlling the effects of microplastics (often implemented by local and global environmental groups); a standardized management strategy to mitigate microplastics in coastal areas is urgently required. There is a need to identify focal causes of microplastic pollution in the marine environment through further environmental research. This would extend to creating more effective policies as well as harmonized and extended efforts of educational campaigns and incentives for counteraction and plastic waste reduction, while mandating stringent penalties for polluting the marine environment. This will help reduce microplastic leakage into the environment.

Published: October 2021

Topographic factors are recognized as one of the key factors influencing vegetation distribution patterns, and studying the interactions between them can contribute to enhancing our understanding of future vegetation dynamics. We used the Moderate-resolution Imaging Spectroradiometer Normalized Differential Vegetation Index (MODIS NDVI) image dataset (2000-2019), combined with Digital Elevation Model (DEM), and vegetation type data for trend analysis, and explored NDVI variation and its relationship with topographic factors through an integrated geographically-weighted model in the Three Parallel Rivers Region (TPRR) of southeastern Tibetan plateau in the past 20 years. Our results indicated that there was no significant increase of NDVI in the entire basin between 2000-2019, except for the Lancang River basin. In the year 2004, abrupt changes in NDVI were observed across the whole basin and each sub-basin. During 2000-2019, the mean NDVI value of the whole basin increased initially and then decreased with the increasing elevation. However, it changed marginally with changes in slope and aspect. We observed a distinct spatial heterogeneity in vegetation patterns with elevation, with vegetation in the southern regions showing higher NDVI than the north as a whole. Most of the vegetation cover was concentrated in the slope range of 8~35°, with no significant difference in distribution except flat-land. Furthermore, from 2000 to 2019, the vegetation cover in the TPRR showed an improving trend with the changes of various topographic factors, with the largest improvement area (36.10%) in the slightly improved category. The improved region was mainly distributed in the source area of the Jinsha River basin and the southern part of the whole basin. Geographically weighted regression (GWR) analysis showed that elevation was negatively correlated with NDVI trends in most areas, especially in the middle reaches of Nujiang River basin and Jinsha River basin, where the influence of slope and aspect on NDVI change was considerably much smaller than elevation.

Rationale for a Climate Club Embedded in Article 6 of the Paris Agreement – A Pathway to Carbon Neutrality
Authors: Stua Michele , Nolden Colin , Coulon Michael
Published: October 2021

Recent times have witnessed an increasing number of countries and private firms pledging carbon neutrality by mid-century. Whilst representing a significant improvement in intentions to tackle climate change, such pledges lack substance and structure. For instance, individual pledges lack coordination and aggregation among peers, while strategies and measures to achieve ambitious targets are largely absent. Moreover, current disagreements obstructing progress in international climate change negotiations further undermine the reliability of carbon neutrality objectives. Effective international policies are needed to foster aggregate mitigation ambitions and the creation of adequate supporting mechanisms. This theoretical paper describes a governance innovation aimed at overcoming such shortfalls and disagreements through a unifying yet customizable pathway towards carbon neutrality. It does so by first outlining a political governance framework based on a climate club interpretation of Article 6 of the Paris Agreement. Secondly, it proposes carbon emission mitigation effort sharing on a per capita basis to ensure efficiency, equity and political feasibility. Thirdly, this paper describes how the supply of certified mitigations of carbon emissions required to satisfy effort sharing-based demand can be assetized as carbon credits by operationalizing Article 6 as a joint certification mechanism. The resulting governance architecture for managing demand and supply of mitigations shifts efforts to tackle climate change from a ‘problem-driven’ cost approach to ‘opportunity-driven’ value creation pathways towards carbon neutrality.
Investigation of Selective Extraction of Phenolic Compounds and of Saccharides From Picea Abies Bark Using Organosolv Solvents
Authors: Zeppetzauer Franz , Nadányi Richard , Kamm Birgit , Putz Robert , Lisý Anton , Šurina Igor
Published: October 2021

Enormous quantities of softwood and hardwood tree bark are generated yearly in the pulp and woodworking industry. Chemical compounds which can be found in bark extracts have important biological properties and therefore a high potential for using in the production of special formulations. In the present study, extraction of Picea abies bark with organosolv solvents was investigated to achieve a high yield of desirable compounds. For the extraction four different solvent ratios of ethanol and water were applied. The temperature range of extraction was set between 40 and 100 °C and stirring velocity of 400 rpm. Extractions were performed with a solid/liquid ratio of 1:20. Yields of phenolics, flavonoids and tannins were determined using gallic acid for total phenolic content (TPC), quercetin for total flavonoid content (TFC) and tannic acid for total tannins content (TTC) as calibration compounds. Qualitative analysis of phenolic constituents was performed after their derivatization, by gas chromatography coupled with mass spectrometry identification. The total yield of bark extract of 14.75 wt.% was achieved by using an ethanol/water ratio of 50% (v/v) and a temperature of 100 °C. Gas chromatography results show 9 aromatic carboxylic acids as phenolic acids and quercetin and (+)-catechin as flavonoid compounds. Highest concentrations of TPC = 3.21 mg gallic acid equivalent/g, TCF = 0.62 mg quercetin equivalent/g and TTC = 0.84 tannic acid equivalent/g were determined at the same process conditions by photometric method. This study determined the conditions for organosolv extraction of useful compounds and suggests that some of extractives, e.g., taxifolin and rhamnetin presented in the spruce bark extracts, have antiviral (SARS-CoV-2) effects. Therefore, this warrants further evaluation of the antiviral properties of spruce bark constituents.

FPGA-based data acquisition and processing systems play an important role in modern high-speed, multichannel measurement systems, especially in High-Energy and Plasma Physics. Such FPGA-based systems require an extended control and diagnostics part corresponding to the complexity of the controlled system. Managing the complex structure of registers while keeping the tight coupling between hardware and software is a tedious and potentially error-prone process. Various existing solutions aimed at helping that task do not perfectly match all specific requirements of that application area. The paper presents a new solution based on the XML system description, facilitating the automated generation of the control system’s HDL code and software components and enabling easy integration with the control software. The emphasis is put on reusability, ease of maintenance in case of system modification, easy detection of mistakes, and the possibility of use in modern FPGAs. The presented system has been successfully used in data acquisition and preprocessing projects in High-Energy Physics experiments. It enables easy creation and modification of the control system definition and convenient access to the control and diagnostic blocks. The presented system is an open-source solution and may be adopted by the user for particular needs.

Welding processes offer a unique capability with a wide range of applications in industries. In recent times, welding has established itself as a tool for large scale additive manufacturing. In general, the quality and repeatability assurance for welding and specifically for additive manufacturing necessitates integrating process monitoring techniques with existing welding and additive manufacturing processes. The process-specific signals such as welding current fluctuations, temperature, and acoustic, generated during the welding operations, make them a suitable candidate for digitization. This chapter comprehensively describes the process monitoring techniques relevant to welding and additive manufacturing. Firstly, various sensors used during welding are described for their construction and working. Subsequently, specific applications of the sensors in digitizing the welding processes are presented.

One of the most remarkable features in the 20th century was the digitalization of technical progress, which changed the output of companies worldwide and became a defining feature of the century. The growth of information technology systems and the implementation of new technical advances, which enhance the integrity, agility and long-term organizational performance of the supply chain, can distinguish a digital supply chain from other supply chains. For example, the Internet of Things (IoT)-enabled information exchange and Big Data analysis might be used to regulate the mismatch between supply and demand. In order to assess contemporary ideas and concepts in the field of data analysis in the context of supply chain management, this literary investigation has been decided. The research was conducted in the form of a comprehensive literature review. In the SLR investigation, a total of 71 papers from leading journals were used. SLR has found that data analytics integrate into supply chain management can have long-term benefits on supply chain management from the input side, i.e., improved strategic development, management and other areas.

Published: October 2021

Based on collected power generation data associated with solar irradiance, PV system conversion efficiency and cell temperature, an hourly solar PV power estimation model by a parallel artificial neural network (ANN) and particle swarm optimization (PSO) algorithm is proposed. Weight matrices related to different seasons and geographic areas for estimation power generations have been trained by real measured operation data. The parallel PSO algorithm with heuristic global optimization technique assists the ANN training process to get near optimal solutions precisely. The accuracy and reliability of estimation is audited by actual details of photovoltaic power stations in various regions and scales. The results of estimation model can not only assist the electricity dispatcher to explicitly monitor the trend of solar power generation in different areas, but also coordinate with traditional power plants to meet load demand more accurately. The presented model will bring benefits to power dispatching for larger scales of intermittent and unstable solar power generation.

Changing climate conditions coupled with the transformations of cultivation practices and land use in sole crop-based sunflower production may significantly decline yield stability of this oilseed crop. Given that sunflower takes the third place in the world oilseed market, with 45 million tons per year, and in the fourth place in vegetable oil production, it is necessary to adapt production technologies toward sustainable agriculture. Considering that, the goal of the research was to analyze and beneficial sustainable production technology of sunflower in intercropping systems. A four-year trial was conducted in Serbia’s agroecological rain-fed conditions (45°34’23.2"N 19°86’18.9"E) using a split-plot design. Two oil types and one confectionary sunflower hybrid were intercropped with common vetch, red clover and alfalfa. Analyses showed that intercropping of sunflower with common vetch resulted in the decrease in almost all sunflower trait values. Also, sunflower × alfalfa intercropping provided to be the most appropriate. The yield of NS Gricko and Rimi PR were statistically on the same level with sole cropping, while alfalfa biomass had better results when intercropped with NS Gricko as compared to sole cropping. Concerning the general belief that yields are more stable in intercropping than in sole crop, further research in this respect is needed, in addition to the research of time and method of sowing.

Background: Nonalcoholic fatty liver disease (NAFLD) is regarded as a component of metabolic syndrome, which has insulin resistance (IR) as the primary physiopathological event. The aim of study was to establish the association between IR, assessed using triglyceride and glucose index (TyG), and histopathological features of NAFLD lesions. Methods: The study included patients with metabolic syndrome. Fasting plasma glucose (FPG), fasting lipid profiles and liver enzymes were measured. IR was assessed by TyG index. Liver biopsy was performed for assessment steatosis and fibrosis. Results: TyG index had a mean value of 8.93 ± 1.45, with a higher value in the patients with overweight (p=0.002) and obesity (p=0.004) than in the patients with normal weight. TyG index mean value of 8.78 ± 0.65 in subjects without NASH, 8.91 ± 0.57 in patients with borderline NASH and 9.13 ± 0.55 in patients with definite NASH. Significant difference was found between subjects without NASH and the ones with definite NASH (p=0.004). The analysis of the area under the ROC curve proved that TyG index is a predictor for NASH (p=0.043). Conclusion: TyG index is a facile tool used to identify individuals at risk for NAFLD, but not for the progression of liver lesions.
