Implementasi Tax on Food dalam Tanggung Jawab Negara Terhadap Hak Pangan Berdasarkan Putusan Mahkamah Konstitusi 39/PUU-XIV/2016
Authors: Putri Intan Permata , Yustikaningrum Rima Yuwana , Devitasari Ananthia Ayu
Published: February 2022

Pasca putusan MK No 39/PUU-XIV/2016 tentang Pengujian Undang-Undang tentang Pajak Pertambahan Nilai Barang dan Jasa dan Pajak Penjualan Atas Barang Mewah dengan permasalahan terkait kriteria 11 jenis komoditas pangan tidak terkena PPN. Namun mahkamah dalam putusan a quo memperluas pemaknaan 11 komoditas pangan sehingga bukan hanya 11 komoditas tersebut yang tidak dikenai PPN. Putusan ini penting dikarenakan meletakkan dasar jaminan hak atas pangan yang menjadi tanggung jawab negara. Permasalahan yang hendak disajikan oleh penulis yakni bagaimana implementasi putusan MK No 39/PUU-XIV/2016 terhadap penerapan PPN pada komoditas pangan? Bagaimana penerapan pajak pada komoditas pangan di berbagai negara? Artikel ini merupakan penelitian hukum normatif dengan menggunakan pendekatan konseptual dan pendekatan perbandingan. Bahan hukum yang digunakan dalam artikel ini meliputi Putusan, Buku, jurnal, laporan dan refenrensi lainnya terkait permasalahan jaminan hak atas pangan khususnya tentang pembebanan PPN atas komoditas pangan. Artikel ini menyimpulkan bahwa pertama, pasca Putusan MK, Pemerintah menerbitkan Peraturan Menteri Keuangan No. 99/PMK.010/2020 yang menambah kriteria barang kebutuhan pokok menjadi 14 item. Namun kriteria ini harus senantiasa dievaluasi dan diperbarui sesuai dinamika sosial, ekonomi, gizi, ekologi dan variabel penunjang lain; kedua, pajak yang dikenakan pada makanan (tax on food) telah diterapkan pada beberapa negara seperti Denmark, Finlandia, Hungaria dan Perancis. Jumlah pangan yang dikenai pajak terdapat beberapa jenis seperti alkohol, tembakau, makanan yang tinggi gula, garam dan lemak jenuh. Tujuannya adalah membangun pola hidup sehat pada masyarakat. Namun dari negara-negara yang telah menerapkan tax on food tersebut tidak ada yang memasukkan bahan pokok sebagai objek pajak. Penerapan bahan pokok sebagai barang yang dikenai PPN tentu saja tidak sejalan dengan konstitusi serta konsep tax on food yang ada selama ini.
Putusan Mahkamah Konstitusi: Dampaknya terhadap Perubahan Undang-Undang dan Penegakan Hukum Pidana
Authors: Wulandari Widati , Putri Nella Sumika , Sulistyani Wanodyo , Chandra Erika Magdalena
Published: February 2022

Putusan Mahkamah Konstitusi (MK) memiliki dampak yang sangat besar bagi perkembangan hukum termasuk hukum pidana. Putusan MK mengakibatkan perubahan norma pidana baik yang di atur dalam KUHP maupun di luar KUHP. Hal ini menarik untuk dikaji apabila dihubungkan dengan perluasan kewenangan MK dari negatif legislator menjadi positif legislator Bentuk putusan MK berupa putusan ‘conditional’ baik konstitusional maupun inkonsitusional bersyarat adalah contoh beralihnya kewenangan MK dari negative menjadi positif legislator. Bagi hukum pidana yang mendasarkan pada asas legalitas, putusan MK terutama yang bersifat ‘conditional’ menimbulkan perdebatan dalam penerapannya, karena dalam kenyataannya tidak seluruh Putusan MK ditindaklanjuti dengan perubahan undang-undang pidana secara formil. Hal ini, menimbulkan berbagai perbedaan dalam penegakan hukum pidana. Putusan MK mengakibatkan perubahan norma hukum pidana melalui dekriminalisasi, depenalisasi, perubahan bentuk delik, maupun penafsiran unsur tindak pidana yang berdampak bagi perubahan hukum pidana materiil maupun hukum pidana formil. Tanpa ada tindak lanjut Putusan MK melalui perubahan perundang-undangan pidana, penegak hukum dapat mengenyampingkan Putusan MK khususnya apabila dihubungkan dengan asas legalitas yang menjadikan undang-undang sebagai sumber hukum utama. Inkonsistensi penegakan hukum tersebut dapat menimbulkan ketidakpastian hukum serta melanggar hak-hak warga Negara.
A Techno-Economic Analysis of Australian Green Steel Production from Hydrogen
Authors: wang changlong , Walsh Stuart , Feitz Andrew
Published: February 2022

Green steel - produced using hydrogen and electricity from renewable energy sources - provides both the means to decarbonize steel manufacturing and a way to facilitate growth of the international hydrogen industry. Australia, with its abundant renewable resources and ample iron-ore deposits, is in an excellent position to participate in this opportunity. We highlight the synergies between the Australian iron-ore industry and the production of green-hydrogen from renewable energy sources. We identify high-potential areas for green steel production by cross-referencing regions of current and future iron-ore extraction against areas of high economic potential for hydrogen production. From these, we select two regions, the Pilbara region of North-Western Australia and the Eyre Peninsula in South Australia, for more detailed case studies. The analysis highlights the advantages of a well-optimised generation mix (in terms of wind, solar, battery, grid connection and salt cavern storage, etc.) in decreasing storage requirements and the resulting production costs. We also demonstrate that green steel production costs could be reduced further if the system could use grid electricity to balance onsite renewable power by participating in the electricity spot market and operating flexibly.

Published: February 2022

The research article is primarily based on development of securities market in Nepal with the aim to analyze the development of securities markets in Nepal. For the accomplishment of the objectives the required data were mainly gathered from secondary sources published by annual report of the Security Board Nepal, different books from library, periodicals, newspaper cuttings, company's magazines etc. From the study, it is found that the number of listed companies has almost been in increasing trend although the growth trend has decreased. This indicates that the NEPSE might have incorporated most of the institutions and thus there is slow growth in listing. Observing the company traded to listed ratios, it can be assumed that NEPSE should monitor the obstacles in the market that are preventing the listed companies to remain untraded.The economic prosperous of the country, the uplift in annual turnover of securities market is quite necessary. Although, the listed companies in NEPSE has been highly dominated by finance companies, the contribution of financial institutions in generating turnover is highest, and the market capitalization of other institutions, which comprises hydropower, promoter share, mutual fund, preference share and other is strongest.

Relationships Between Public Attitudes Toward Stuttering and Autonomic and Subjective Indices of Anxiety
Authors: St. Louis Kenneth , Öge-Daşdöğen Özlem , Johnson Lauren E. , Litzinger Jennifer G. , Myers Lauren , Donai Jeremy
Published: February 2022

Introduction: Research has shown that adults who stutter have reacted with increased skin conductance and lower heart rates when confronted with videos of severe stuttering compared to videos of fluent speech. It has not been clearly established how these physiological indices or autonomic arousals are related to stuttering attitudes. The current study sought to compare physiological and psychometric measures of anxiety with stuttering attitudes.Method: In a multiple-baseline design, 18 normal hearing university students listened to short samples of stuttered, masked, and normally fluent speech while their skin conductance and heart rate variability were being monitored by an Empatica E4 wristband device. Pre-experimentally and after each speech condition, they rated their comfort level on a 1–9 scale. Participants filled out the State-Trait Anxiety Inventory (STAI ) (Spielberger, 1977) prior to the physiological measures and the short state anxiety inventory afterwards. At the end, they filled out the Public Opinion Survey of Human Attributes–Stuttering (POSHA–S).Results: No significant main effects were observed for either autonomic measure for the three speech conditions, but interactions were significant. Individual participant analysis revealed that every respondent reacted differently to the skin conductance or heart rate variability. By contrast, mean subjective comfort ratings were more often lower after hearing stuttered or masked speech and higher after hearing fluent speech. Correlations between all the measures and the POSHA–S summary scores revealed little relationship between the autonomic measures and stuttering attitudes, but higher levels of state or trait anxiety were associated with more positive beliefs about people who stutter. In contrast, lower levels of anxiety tended to be associated with more positive self-reactions to those who stutter.Conclusion: This study did not replicate previous reports of heightened autonomic reactions to stuttering among nonstuttering adults, although psychometric measures suggest a relationship between anxiety and stuttering attitudes. Further research should explore these relationships, especially with young children.

In this paper, we firstly review the quasi uniformly accelerated motion (QUAM) with Fermi derivative by cold plasma in Heisenberg space. We define new quasi uniformly accelerated potential electric energy of quasi normal magnetic biharmonic particles and some Lorentz fields. Moreover, we design the new relationship between the quasi uniformly accelerated motion and the Fermi parallel transportation in cold plasma. Also, we collect new physical geometric designs for a quasi uniformly accelerated motion of normal magnetic biharmonic particles in Heisenberg space. Finally, we construct quasi uniformly accelerated potential electric energy with respect to its electric field and some quasi curvatures.

Published: February 2022

For the sake of ensuring the energy security of Ukraine, the trouble-free operation of the oil transportation system becomes of strategic importance. The problem is exacerbated in connection with the long service life of individual objects of the system, which leads to degradation of the properties of the pipe material due to corrosive and erosion processes, which is enhanced by the effect of time-varying loads. Today, in world practice, various methods are used to strengthen defective sections of pipelines: installation of steel, plastic and fiberglass couplings, winding of an elastic composite tape, the use of reinforcing composite couplings, etc. To study the effect of microcracks, corrosion and erosion defects on the Druzhba oil pipeline of OJSC Ukrtransnafta with an installed bandage, full-scale tests of a defective section of a pipe (material - 17GS steel) reinforced with bandages made of a similar material using a UI1 / 200 GK installation were carried out. As a result of research, the pressure of its destruction was determined. During the tests, strain gauging was used to determine pipe deformations. Comparison of the values of stresses obtained experimentally and analytically confirmed that the use of bands on defective sections of the pipeline is an effective means for extending their service life. For a more accurate and detailed analysis of the reliability and durability of oil pipelines, a study of the defective parts (break point) cut from the pipeline was carried out. As a result of the studies carried out on the models - "cutouts", corrosion defects with a depth of up to 5 mm were registered, which is about 55% of the loss of metal, however, the pipe was not destroyed by these defects, but by a defect of the "crack" type. To obtain the profile of the defect from the model - "cutout", scanning was carried out using a sensor fixed on a mobile tripod connected to a computer via an ADC. At the next stage of research, the assessment of the residual resource was carried out using the analysis of full-scale kinetic curves of damage to hazardous sections of the oil pipeline through experimental studies of models - "cutouts". A fatigue curve has been constructed, which can later be used to predict the fatigue life of such elements.
Reliability of results of use of complex geophysical studies in the process of control of development of oil and gas deposits
Authors: Fedoryshyn D. D. , Trubenko О. М. , Fedoryshyn S. D. , Trubenko А. О.
Published: February 2022

The paper considers modern methods for determining the position of gas-liquid contacts in terrigenous deposits at oil and gas condensate fields in Ukraine. The results of laboratory studies of a representative core collection (87 samples) in the petrophysical laboratory of IFNTUOG made it possible to establish the reservoir parameters and lithological characteristics of reservoir rocks of Carboniferous and Neogene sediments, which made it possible to reliably estimate the reservoir parameters of productive formations. The results of well studies, in particular, obtained during the isolation of oil and gas-saturated reservoir rocks and monitoring the dynamics of changes in oil-water and gas-water contacts, made it possible to form an optimal informative complex of geophysical methods for effective prospecting and development of oil and gas fields. Direct studies of the identified reservoir rocks made it possible to establish that the geological sections of the Jurassic, Cretaceous and Neogene systems of prospecting areas are filled with both hydrophilic and hydrophobic lithotypes of rocks, which have different effects on the readings of electrical and radioactive methods. Reasonably, the maximum value of the electrical resistivity, the maximum oil saturation coefficient (Кo), as well as the minimum value of the water saturation coefficient (Кw), which is typical for oil and gas-saturated formations, must correspond to the condition for displaying these parameters in completely water-saturated rocks. In this case, the boundary of the transition zone will be displayed by the bottom of the maximum radio-saturated layer and the top of the aquifer in this rock. Confirmation of the above is seen from the fragments of geophysical data processing, electrical and neutron studies in the presence of low and high salinity, drilling fluids and drilling fluids. The analysis of the efficiency of using the methods of pulsed neutron-neutron logging (PNNL) and neutron gamma-ray logging (NGL) when monitoring the change in the position of the GLC to prevent watering of productive formations is carried out. According to the research results, it is proposed to use a complex of nuclear physical methods in the process of monitoring the dynamics of changes in NWC, in particular, neutron gamma logging, repeated neutron logging, as well as in the process of drilling conducting electrical methods of imaginary resistance and unauthorized potentials.

Published: February 2022

The problem of choosing the rational control of non-stationary processes in complex gas transmission systems caused by instability of loading in the conditions of limited volume of gas transit is considered. Control effects in such conditions must ensure the transfer of the object from one point of the functional phase space to another, maintaining its specified state under different perturbing effects while fulfilling the condition of minimum total costs. The results of analytical studies of the nature of the flow and duration of non-stationary processes in complex gas transmission systems caused by the exclusion from the mode of operation of individual compressor stations are presented. A mathematical model of the gas pipeline is constructed taking into account the influence of compressor stations on the basis of classical equations of gas flow energy and continuity using the functions of the Dirac source. The implementation of the created mathematical model by applying the integral Fourier and Laplace transforms allowed to obtain in analytical form the dependence that reflects the law of fluctuations in time of mass flow of gas in the initial and final cross section of the pipeline. The constructed dependences of the gas transmission system productivity trend at its beginning and end showed the influence of compressor station placement in the gas transmission system, in particular its serial number on the route number, on the nature of the nonstationary process caused by its shutdown, in particular on the nonstationarity duration. These tasks are the main tasks of operational optimal management of gas transport through main gas pipelines, which allows to solve the problem of uninterrupted supply of gas consumers. For optimal control problems, an algorithm of the method of step variations is proposed, according to which variations of inlet pressure and flow are localized, ie taken as constants at this step, and change of control function mainly affects only outlet pressure. systems, especially if they are not fully loaded.
Comparative evaluation of the executive mechanism of the balancing drive of the rocking machine equipped with a long-running stand
Authors: Kharun V. R. , Senchishak V. M. , Popovych V. Ya. , Shostakivskyi І. І.
Published: February 2022

The article studies long-running drive of a downhole rod pumping unit, the design of which combines a traditional two-arm balancing drive (rocking machine) and a long-running stand. Modern downhole rod pumping units can extract oil, usually from one or two layers of wells up to 3500 m deep with a liquid flow rate from a cubic meter to several hundred cubic meters per day. It is investigated that the characteristics of balancing drives, performed by a number of world manufacturers allow the usage of pumping equipment in the range of fluid flow rate from the well from 1 to 40 m3 day. There is a general global trend of reducing the oil wells’ flow, as most oil fields are in the late stage of development, and therefore most traditional rocking machines are operated with low efficiency. Because the vast majority of of Ukrainian oil-production enterprises’ wells are equipped with beam pumping units their replacement by other types of the downhole rod pumps' drives requires significant investments. Equipping of a traditional balancing drive with a long-travel stand can improve drive’s technical characteristics. Determination of the design changes’ influence on kinematic and dynamic characteristics has been performed for two balancing options: 1 – traditional balancing of the drive with crank counterweights, placed on the cranks of the rocking machine in combination with a long-running stand and 2 – when the balance drive is used only to convert movement of a rope suspension bracket, and counterweights are placed on a long-running stand. It has been calculated that the first balancing variant allows to reduce the maximum torque up to 27.7 %, and by the counterweights placing on a long-running stand, the reduction of the maximum torque can be up to 62 %. It is proposed to use the standard deviation of the torque as a criterion for assessing the quality of balance.

Authors: Makarenko V. D. , Liashenko A. V. , Vytyaz О. Yu.
Published: February 2022

During the operation of oil and gas wells there is a constant decline in production. The reason may be various factors, such as the reduction of the internal space of the tubing due to the deposition of hydrate-paraffins, asphaltenes, resins and mineral salts. To prevent and clean these deposits, various control methods are used: the use of special coatings on the inner surface of the pipes, the introduction into the pumped stream of various chemical reagents, sonication, magnetic treatment, mechanical methods, etc. However, some of them are considered inefficient, economically unprofitable or quickly fail.That is why an improved design of a device for cleaning the inner surface of tubings of oil and gas wells was proposed. The device refers to the equipment of the oil and gas industry, namely as a mechanism for restoring the internal space of well pumps. Calculations for the design of cleaning devices for different diameters of tubing are given. Kinetic calculations of the movement of the cleaning mill in tubing pipes under the action of hydraulic forces were performed. Based on the obtained equations, in the process of design development, the dimensions and shapes of the working (main) and additional (reverse) cutters were calculated, the masses and strength characteristics of structural elements (pins, traverse, cable, bolted joints, etc.) were selected. Provided the necessary rigidity and reliability of the entire cleaning device. Thus, the proposed design developments in combination with the previously known will allow to obtain a new positive effect, which is to improve the quality of cleaning of tubing. Industrial tests of the developed design on objects showed significant advantages in comparison with domestic and foreign analogs.

Authors: Mykhailiv І. R. , Boiko А. P. , Zhuchenko H. О. , Yatsyshyn М. М.
Published: February 2022

At present, mathematical methods are becoming a necessary tool for geological research. Computer processing of geological data is widely used in modern methods of studying the oil and gas content of the subsoil. Therefore, the description of the structures as possible oil and gas traps, we conducted as an analysis of their quantitative parameters, which allowed to substantiate certain established patterns. In order to identify patterns in the relationships between the numerical parameters of folded structures, we conducted computer geological and statistical modeling of the studied objects of the Boryslav-Pokutska zone using correlation and cluster analysis. In general, correlation analysis allows the analysis of a set of defined quantities and is aimed at identifying and studying the systems that form some of the quantities included in this set. Classification of any objects by content groups is carried out by the method of cluster analysis. A large volume of quantitative indicators has been developed to model the processes that have formed local structures and to determine the patterns of their distribution. Quantitative indicators can be used to evaluate the results of studies of the distribution of tectonic stresses and strains, which will contribute to a more reliable prediction of oil and gas potential. In turn, this will significantly increase the geological efficiency of oil and gas exploration in the areas of the Boryslav-Pokutska zone of the Pre-Carpathian Foredeep. The modern shape of structures and their spatial location is a consequence of tectonic forces over a fairly long period of geological time. Different manifestations of tectogenesis activity in different epochs cause certain changes in the structural plan of geological bodies and thus affect their possible oil and gas potential (formation, disintegration and reshaping of traps and, accordingly, deposits). The structures of the Boryslav-Pokutska zone have undergone a complex and long path of formation: from sedimentary flysch folds to very complex post-sedimentary structural forms, which is due to the influence of the magnitude and nature of the application of formative tectonic forces. Under the influence of tectonic forces of different nature, various morphological structural forms were formed. The morphological varieties of structures can be described by numerical parameters, which can be used as a basis for the classification of structures of the Boryslav-Pokutska zone.

O objetivo do presente trabalho foi avaliar a determinação da fibra em detergente ácido em solução de ácido sulfúrico 1M em comparação a fibra em detergente ácido em solução de ácido sulfúrico 1 N com CTAB (20g). Para isso, foram utilizados três ingredientes: casca de soja, farelo de girassol e feno de tifton. As análises de FDA foram realizadas em auto-clave, foram pesadas 0,5g de amostra em cadinhos filtrantes previamente pesados, em seguida adicionou-se 50 mL de solução ácida para cada amostra. Os teores de FDA foram obtidos utilizando-se duas soluções ácidas, a solução padrão era composta de 28 mL de ácido sulfúrico (H2SO4) com 96-98% de pureza e 20 g de brometo-cetil-trimetilamônio (CTAB), para 1L de solução. A solução teste era composta por H2SO4 na concentração 1M (55 mL para 1L de solução).

O objetivo do presente trabalho foi a determinação do tempo e potência ideais para determinação da matéria seca dos fenos de alfafa (Medicago sativa) e Tifton (Cynodon dactilon) no forno de microondas tendo como controle a matéria seca obtida em estufa de circulação forçada de ar a 105 ºC por 12 horas. As amostras foram submetidas a dois processamentos diferentes: picadas em picadeira elétrica em partículas de aproximadamente 3 cm e moídas em moinho tipo faca utilizando peneiras com crivos de 1 mm (16 mesh). Para determinação da matéria seca pesaram-se 5g de amostra em béquer de vidro e posteriormente submetidas ao forno microondas. Foram analisadas cinco etapas com diferentes tempos sucessivos de exposição da amostra à fonte de calor, todas as etapas totalizaram 10 min. Para cada etapa foram pesadas cinco repetições de cada amostra (feno de alfafa picado, feno de alfafa moído, feno de tifton picado e feno de tifton moído). Na primeira etapa a amostra foi submetida a 1 min de exposição ao microondas, O procedimento foi repetido mais nove vezes, até completar 10 min de exposição da amostra ao microondas. Na segunda etapa as amostras foram submetidas a 2 min de exposição, repetindo-se o processo por mais quatro vezes, totalizando cinco pesagens em 10 min. Na terceira etapa os tempos de exposição foram 2min, 4min e 4min, sendo as amostras pesadas ao final de cada tempo em questão. A quarta etapa constou dos tempos 1 min, 4min e 5min de exposição das amostras, sendo realizadas três pesagens em 10 min. Na quinta etapa as amostras foram submetidas a 10 min de exposição direta ao microondas e o pesadas ao final do tempo. Este procedimento foi repetido para três potências: 40%, 60% e 80% da potência máxima do forno microondas.

Published: February 2022

Dentro da cadeia produtiva atual, a suinocultura e principalmente a avicultura, apresentam um desenvolvimento tecnológico de grande velocidade. Dentro desse contexto, é importante que fatores como nutrição, genética e sanidade caminhem juntos para que obtenhamos um funcionamento adequado. Na área da nutrição animal, é muito importante nos atentarmos não só pela questão da quantidade más também, pelo caráter da qualidade dos ingredientes que estamos utilizando na formulação de rações. Uma das qualidades de uma dieta está voltada para a característica da energia cuja presença, determina o desempenho da criação, principalmente em aves. A utilização de óleos e gorduras na alimentação de aves apresentam como características, um aumento da energia das rações, melhoram a palatabilidade dos alimentos além de melhorar a digestão e absorção de constituintes não lipídicos dos ingredientes. Os óleos de origem vegetal mais utilizados dentro da nutrição de monogástricos são: óleo de soja, óleo de girassol, óleo de algodão, óleo de linhaça e óleo de canola. Essas substâncias energéticas nas rações para poedeiras podem contribuir de forma benéfica para o peso dos ovos e da gemas, porém, não contribuem para um ganho de peso das aves, o que julgamos ideal já que as poedeiras necessitam ser mais leves para não comprometer a postura.

Published: February 2022

Muitas vezes o veterinário buiátrico depara-se com efectivos bovinos leiteiros de pequena e média dimensão onde existem indícios clínicos e epidemiológicos da presença de paratuberculose, como é o caso da realidade pecuária portuguesa. Estas explorações, geralmente com um encabeçamento inferior a 100 animais, exigem uma abordagem sanitária e técnico-económica específica. No presente artigo, foram descritos aspectos epidemiológicos, clínicos e laboratoriais a ter em consideração para a elaboração de uma decisão final, por parte do produtor, de modo a controlar ou erradicar a doença. O conteúdo deste trabalho recebeu uma menção honrosa atribuída pela Associação Portuguesa de Buiatria, em Abril de 2008, correspondente ao “Prémio de Buiatria Pfizer Saúde Animal”, ao qual o primeiro autor se candidatou.
