Control por Modos Deslizantes de la Relación de Exceso de Oxígeno en una PEMFC Interconectada a un Motor de CD mediante un Convertidor Boost
Authors: Cervera-Ceballos María , Rodriguez-Blanco Marco Antonio , Vazquez-Ávila José , Alazki Hussain
Published: April 2021

In this work, a proton exchange membrane fuel cell (PEMFC) is used to electric energy supply to a permanent magnet DC motor in a sustainable way and the inlet air flow in the cathode is manipulated to ensure the PEM fuel cells efficient operation. A boost-type DC/DC converter is connected to the PEMFC, it is used with a PI linear control loop to regulate the speed of the DC motor under some possible load disturbances. In addition, a nonlinear sliding mode control (SMC) is designed for regulated the excess oxygen ratio considering constant the temperature and humidity of membrane, to achieve the PEM full cell operate in the ohmic region of the polarization curve, to avoid the oxygen starvation at the cathode and to prevent damage to fuel cell components. The results are validated using the internal models of the PEMFC and the power electronics from SimPowerSystems library of Matlab/Simulink.

Published: April 2021

A hexapod robot control system hardware architecture is presented. The control system is integrated in an FPGA XC6SLX16-Spartan6. The design is developed using hardware description language, VHDL. A robust architecture, divided into three logical state machine blocks, is implemented in the FPGA. Block one consists of a serial communication system for the information interchange between the user and the FPGA. The second block corresponds to the sequential circuit and data manager in charge of controlling the functions of the entire architecture. The third block is an 18-channel PWM pulse generator with a progressive duty cycle change control to perform robot movements. The system is designed to allow the user to download a complex movements sequence by combining different positions and waiting times. The architecture allows to save up to 10 movements different sequences in the internal memory block. Additionally, it allows modifying any sequence in real time, without affecting the robot operation. The architecture controls 18 servomotors allowing 18 degrees of freedom to the robot. The performing and movement test of the robot are presented.

This project presents the design of an electrical power generation system, which takes advantage of a person’s movement when exercising on a static bicycle. This system is implemented in a gym located in Suchiapa, Chiapas. The analysis is carried out of three categories of people: high performance athlete, occasional athlete and sedentary person, to evaluate the calories consumed per day and exercise time on static bicycle. This information provides an estimate of the energy generated in one day, to compare the receipt of power consumption of CFE before and after the system. The static bicycle is mechanically attached to a generator by means of a support, followed by a diode allowing the passage of the electric current with characteristics similar to a switch, which is connected to a voltage regulator that maintains a constant voltage level. The regulator is coupled to the electric accumulator and an inverter. The latter is in charge of converting the direct current input voltage and alternating current output. By implementing the mechanism with nine static electric bicycles, an energy saving of 17.57 % is obtained.
Caracterización térmica y eléctrica de un sistema fotovoltaico de alta concentración de disco parabólico

Published: April 2021

Este artículo presenta el estudio experimental que consiste en el análisis del desempeño térmico y eléctrico de un sistema HCPV que cuenta con dos discos parabólicos y sus respectivas unidades de conversión de potencia (PCUs) configurados en una óptica especial conocida como XRX-Köhler. Este sistema utiliza celdas multi-unión, que, a pesar de su alta eficiencia, no utilizan entre el 60-70% de la radiación recibida por lo que esta energía debe ser retirada con un sistema de enfriamiento para mantener su temperatura dentro de un intervalo que asegure su integridad y el mejor desempeño de la misma. A diferencia de las celdas de unión sencillas, las MJ pueden operar a más altas temperaturas con eficiencias aceptables de producción eléctrica. Esta característica de operar en un rango amplio de temperaturas (~ 90°C), puede hacer que sistemas térmicos de aplicaciones solares funcionen con el calor residual y así mejorar el desempeño total del sistema. Se ha desarrollado una serie de campañas de pruebas experimentales para la evaluación tanto de las curvas I-V en forma instantánea como las eficiencias instantáneas eléctrica y térmica obteniendo valores de ~24% y de ~53%, respectivamente.

We Are the Stories We Tell
Authors:   Iowa State University, Cardinal-Pett Clare
Published: April 2021

The argument outlined in this paper is simple: understanding what actually happened in the Americas before 1492 CE enlightens our understanding of the present. I hope to contribute to the broad academic discourse about global issues by addressing false assumptions that do not serve to illuminate real places, people, and practices. Perhaps one of the concerns mentioned in the conference call for papers, an“increased contemporary need to develop strategies to cope with future stresses,” should be addressed, in part, by rethinking the stories we tell about how we got to the current human condition.
(re)Weave: Adapting Urban Obsolescence in Syracuse
Authors:   Syracuse University, Marinic Gregory , Leonard Zeke ,   Syracuse University
Published: April 2021

It has been over fifty years since the beginning of the decline of the American industrial city. After World War II, urban life in the United States began to fracture along social, economic, and demographic lines. The rise of the interstate highway system facilitated the simultaneous collapse of downtown retail districts; advancing urban decay stood in marked contrast to a thriving, homogeneous, trans-continental suburban culture. Today, widespread obsolescence has catalyzed and accelerated to embody the future of shrinking cities in the RustBelt.
“Planetary Reconstruction”: Richard Neutra’s School Lessons from Puerto Rico
Authors:   Mississippi State University, Esenwein Fred
Published: April 2021

Puerto Rico, while a U.S. territory, lacked the education, health, and sanitation infrastructure found in the continental United States. Neutra’s task was to design facilities to improve the infrastructure. While the aesthetic of the buildings is considered Modernist architecture, Neutra was very sensitive to the structures of local communities. His school designs were didactic in the way people engaged the architecture by learning about fluid mechanics and sanitation through passive designs and planning. Gardens and agricultural practices were introduced to improve food and nutrition. Education and food reforms required local knowledge even though there is a broader scientific knowledge that understands how these conditions can thrive in a particular locality. Architecturally, Neutra adjusted the Modernist style to perform in tropical Puerto Rico. Having contributed to the development of Puerto Rico and anticipating the economic boom in the U.S., Neutra’s proposal for the American community is one that was developed from the global south meant to conserve local values, and yet it was conceived as a model plan that was independent of a particular location.

The Politics of Memory: Constructing Heritage and Globalization in Havana, Cuba
Authors:   Marywood University, Fuentes Gabriel
Published: April 2021

Since granted world heritage status by the United Nations Educational, Scientific, and Cultural Organization (UNESCO) in 1982, Old Havana has been the site of contested heritage practices. Critics consider UNESCO’s definition of the 143 hectare walled city center a discriminatory delineation strategy that primes the colonial core for tourist consumption at the expense of other parts of the city. To neatly bound Havana’s collective memory/history within its “old” core, they say, is to museumize the city as ”frozen in time,” sharply distinguishing the “historic” from the “vernacular.”While many consider heritage practices to resist globalization, in Havana they embody a complex entanglement of global and local forces. The Soviet Union’s collapse in 1991 triggered a crippling recession during what Fidel Castro called a“Special Period in a Time of Peace.” In response, Castro redeveloped international tourism—long demonized by the Revolution as associated with capitalist “evils”—in order to capture the foreign currency needed to maintain the state’s centralized economy. Paradoxically, the re-emergence of international tourism in socialist Cuba triggered similar inequalities found in pre-Revolutionary Havana: a dual-currency economy, government-owned retail (capturing U.S. dollars at the expense of Cuban Pesos), and zoning mechanisms to “protect” Cubanos from the “evils” of the tourism, hospitality, and leisure industries. Using the tropes of “heritage”and “identity,” preservation practices fueled tourism while allocating the proceeds toward urban development, using capitalism to sustain socialism. This paper briefly traces the geopolitics of 20th century development in Havana, particularly in relation to tourism. It then analyzes tourism in relation to preservation / restoration practices in Old Havana using the Plaza Vieja (Old Square)—Old Havana’ssecond oldest and most restored urban space—as a case study. In doing so, it exposes preservation/ restoration as a dynamic and politically complex practice that operates across scales and ideologies, institutionalizing history and memory as an urban design and identity construction strategy. The paper ends with a discussion on the implications of such practices for a rapidly changing Cuba.
The Dark God of Efficiency and the Economical Forms of Eladio Dieste
Authors:   South Dakota State University, Garcia Lammers Federico , Garcia Fritz Jessica ,   South Dakota State University
Published: April 2021

“Efficiency is the dark god to whom we sacrifice so many things”. Since the rise of the Industrial Revolution in the 18th century, “innovation as progress” became a mantra of industrialized societies. As new materials and the methods for making them emerged, architectural education shifted from an École des Beaux-Arts education rooted in the principles of classicism to an arts and crafts based education definitive of the Bauhaus. This shift allowed architecture students the opportunity to work with new materials such as iron, steel, and reinforced concrete. Throughout the 20th century, innovations came less in the form of the methods that impacted material and construction and more in the form of representational tools. By the end of the century, digital tools dominated both architectural education and practice. In the last half of the 20th century Uruguayan engineer, Eladio Diesterecognized a representational fetish in architecture as he claimed that “current methods of construction and even our professional training teach us to do projects, not build buildings―we think more about the plans than the structure, or we only think about the structure through the framework of the plans.” In his own practice, Dieste was able to collapse the space between representational and material knowledge by focusing on what he defined as Cosmic Economy. The first half of this paper will introduce the circumstances and methods associated with Dieste’s practice in the context of Cosmic Economy. The second half of the paper will describe representation and construction processes as a means to exercise material knowledge in an ongoing student project at South Dakota State University.
Measuring the surface temperature of light-emitting diodes by thermoreflectance
Authors: Zheng Dong-Guang , Shin Dong-Soo , Shim Jong-In
Published: April 2021

As the latest applications of LEDs require more harsh operating conditions, understanding the device thermal properties becomes more essential for further improving the device efficiencies. In applications where heat dissipation can be a critical issue, thermoreflectance (TR) can be utilized as a useful noncontact measurement technique for analyzing the thermal properties. In this paper, we investigate the TR method of measuring the surface temperature, using a lateral-type blue LED chip under high-power operation. The TR we employ measures the change in reflectivity from the Au metal electrode. By comparing with surface/junction temperatures measured by other methods based on the thermocouple and the forward voltage, we find that the TR method can provide accurate and reliable results of measuring the surface temperature of modern LEDs. A useful insight can also be obtained from the temperature distribution on the LED chip surface.
Promoting urban security through community participation: evidence from Wa, Ghana
Authors: Marfo Samuel , Gyader George , Opoku Stephen Kwame
Published: April 2021

Crime remains one of the major threats to urban communities in Ghana. Ostensibly, the hitherto approach in crime control had been targeting statutory institutions, notably the Ghana Police Service, to the neglect of community level participation, which has become critical due to the increase in crime levels and manpower challenges facing the law enforcement agencies. Against this background, this paper examined how community members contribute to the promotion of security in Wa, a cosmopolitan community in the Upper West Region of Ghana, which often escapes official reports. Forty-three (43) community crime control actors in addition to three key informants were selected purposely in a case study design. Primary data were gathered through interviews and focus group discussions. The study found that community actors complement the efforts of the police by supplying relevant information on crime and offenders resulting in the arrest and prosecution of offenders in the law courts; providing logistical support such as motorbikes and fuel to the police; arresting and handing over suspected criminals to the police; engaging the services of private security operatives; as well as undertaking community patrols often known as ‘neighbourhood watch’. Given the critical role of citizens in crime prevention and control, and the promotion of communities’ safety, the paper recommends that the police should periodically organise workshops to educate community members on modern crime trends and strategies so as to improve their skills in crime control and detection.
A 71-Year-Old Man Presenting with Anemia and a Solitary Skin Lesion Associated with Primary Cutaneous Marginal Zone Lymphoma
Authors: Khudyakova Mariya
Published: April 2021

A 71-year-old man with a solitary red lesion on his left arm, which initially thought to be a hematoma, was admitted for inpatient evaluation of anemia, which after a positive direct Coombs test was qualified as autoimmune hemolytic anemia. The patient also presented with hoarseness and biopsies from the swelled nasopharynx and an enlarged right tonsil were obtained. Due to uncertain diagnosis and the patient’s previous history of malignancy, (low grade lymphoproliferative lymphoma) skin and bone marrow biopsies were performed. Unfortunately, the patient’s status rapidly deteriorated as a result of septic shock. The obtained skin, nasopharynx, and tonsil biopsies became available after the patient died and showed marginal zone lymphoma with no evidence of lymphoproliferative neoplasm in the bone marrow.   

This case demonstrates the diagnostic complexity of nodal marginal zone lymphoma complicated by severe life-threatening autoimmune hemolytic anemia in an elderly patient with multimorbidity, which presents management challenges for health care providers.

Мақолада Юсуф Хос Ҳожибнинг “Қутадғу билиг” асари қадимги туркий ҳалқларнинг ҳурмат категориясини изоҳлашда муҳим манбалардан бири сифатида тадқиқот объекти сифатида танланди. Туркий халқлар ҳаётида “Қутадғу билиг” асари жамият-тил-маданиятни қамраб олган ва уларга асосланган насиҳатлар, мақол ва масаллар орқали жамиятдаги муаммоларга оқилона ечим излайди. Бу халқаларнинг бир-бирига узвий боғланиши айни пайтда шахс маданиятини ҳам акс эттиради. Агарда улар орасидаги мана шу узвийлик йўқолса, нутқнинг таъсир кучи ҳам ўз-ўзидан йўқолади. Бу анъана, нафақат ХI аср учун, балки бугун учун ҳам аҳамиятли. “Қутадғу билиг” асари ҳурмат категориясини тилшунослик нуқтаи назаридан фақат вербал шаклда эмас, новербал (паралингвистик) жиҳатдан ҳам тадқиқ этишда яхши натижалар беришини кўрсатишга қаратилди. Тадқиқотда ҳурмат ‘-im’ эгалик қўшимчаси ‘sen’, ‘siz’ олмошлари ва ‘girmek’, ‘çıkmak’ феъллари билан тилшунослик асосида; el, ayak, baş жестлари ва yer, şeref köşesi, baş köşe символлари билан паралингвистик асосда юзага келиши мисоллар ёрдамида изоҳланди. Бундан ташқари, келтирилган мисолларга ўрни билан ўзбек ва турк тилидан муқоясалар ҳам келтирилиб тушунтириди.
НЕСОБСТВЕННО-ПРЯМАЯ РЕЧЬ КАК СРЕДСТВО СОЗДАНИЯ ИНДИВИДУАЛЬНОЙ КАРТИНЫ МИРА ДИСКУРСИВНОЙ ЛИЧНОСТИ ПЕРСОНАЖА И АВТОРА

Published: April 2021

Антропоцентризм художественного дискурса отображается в дискурсивной личности автора и персонажа. Дискурсивная личность автора, проявляемая в авторской модальности и интенциональности, определяется всей системой языковых средств, используемых в художественном дискурсе, что отражается в отборе лексических средств, в семантической, прагматической и композиционной структуре дискурса. Вместе с тем очевидно, что некоторые фрагменты дискурса выражают дискурсивная личность автора и персонажа с наибольшей степенью, что позволяет рассматривать их в качестве вербальных маркеров антропоцентризма. Вербальными маркерами дискурсивной личности персонажа являются: а) художественный диалог; б) несобственно-прямая речь; в) графические средства, характеризуемые выражением авторской модальности и направленные на характеризацию образа персонажа в коммуникативно-прагматическом, когнитивном, культурном и психологическом аспектах. Несобственно-прямая речь (далее — НПР), являясь сложным языковым явлением, основанным на взаимодействии речи автора и персонажа, способствует, с одной стороны, раскрытию концептуальной информации, с другой стороны, — выражению авторской модальности и интенциональности. Сущностной характеристикой НПР является её двуплановость, которая может быть представлена неравнозначно, т.е. в зависимости от прагматической установки на первый план может выходить дискурсивная личность (ДЛ) автора или персонажа. Другой характеристикой НПР является стилистическая маркированность и стилистическая гетерогенность, проявляемая в сентенции различных стилевых регистров, создающих контрастирование литературных и разговорных пластов, лексических и синтаксических единиц.

Advanced Performance Metrics and their Application to the Sensitivity Analysis for Model Validation and Calibration
Authors: Agrawal Urmila , Etingov Pavel , Huang Renke
Published: April 2021

High quality generator dynamic models are critical to reliable and accurate power systems studies and planning. With the availability of PMU measurements, measurement-based approach for model validation has gained significant prominence. Currently, the model validation results are analyzed by visually comparing real--world PMU measurements with the model-based response measurements, and parameter adjustments rely mostly on engineering experience. This paper proposes advanced performance metrics to systematically quantify the generator dynamic model validation results by separately taking into consideration slow governor response and comparatively fast oscillatory response. The performance metric for governor response is based on the step response characteristics of a system and the metric for oscillatory response is based on the response of generator to each system mode calculated using modal analysis. The proposed metrics in this paper is aimed at providing critical information to help with the selection of parameters to be tuned for model calibration by performing enhanced sensitivity analysis, and also help with rule-based model calibration. Results obtained using both simulated and real-world measurements validate the effectiveness of the proposed performance metrics and sensitivity analysis for model validation and calibration.
Modified Startup Delay Providing Circuit for Integrated Circuits
Authors: Patel Darshil
Published: April 2021

Power management in integrated circuits is critical and some
ICs require voltages to be applied in a particular sequence. Integrated
circuits consist of various distinct sub-circuits and power delivery to each of
those circuits at the proper time is required for proper operation. Some
examples are Subscriber line interface circuit (SLIC), switching voltage
regulators, etc. Thus, startup delay circuits are necessary as they ensure the
delivery of power to circuits at the appropriate time. Time delays are conventionally
generated by resistor-capacitor pair but the time constant is very small, for
higher time delay, we have to increase resistor-capacitor sizes which require
more space and is not economical. In this paper, a new technique is proposed
for the generation of sufficient time delays eliminating the need for larger
resistor and capacitor combination. The proposed startup delay circuit is
designed in 180 nm. CMOS process and simulated in LTSpice.
Medieval Norwegian Wooden (Stave) Churches: Built Heritage and Places of Memory
Authors: Szilágyi Kata , Sand-Eriksen Anette
Published: April 2021

This paper focuses on the Norwegian medieval religious buildings called stave churches. The word stave (meaning ‘post, pole’ in Norwegian) derives from the buildings’ post and lintel construction, giving the churches their characteristic style. The structures display a highly developed tradition of wooden Christian buildings, which during the Middle Ages (1050–1500) where the most common in Norway, their number can be estimated at around a thousand. There were probably at least as widespread in other areas (e.g. on the territory of present-day Germany and Russia), but they did not remain in such a large number from the early period. However, the number have declined dramatically, and today only 28 are preserved. The article aims to expand the knowledge of the unique and irreplaceable wooden architecture of the stave churches. Although we consider the wooden churches to be one of the characteristics of Scandinavia traditionally, they mix and carry the influences of other cultures and countries. The heritage and memorial role of wooden churches, as well as the motif of the combination of different architectural and religious elements, represent an interesting comparison to similar phenomena in the Carpathian Basin. Transylvania and especially the Maramureş region are also famous for their wooden churches and the rich carved and painted iconostasis.

Published: April 2021

According to the WWF, forests cover 30% of the earth’s surface and act as important support systems in balancing the world ecosystem (World Wide Fund for Nature (WWF) n.d.). They are home to many plant and animal species and a critical source for sustaining human livelihood. Human dependency on forest products is the backbone of not only the survival of a nuclear family but also contributes to the economy of the local community. As known, Malaysian forests consist of mountainous forests, tropical rainforest, swamps and coastal forests. As for traditional Malay society, they relied heavily on forests for survival. Besides its functioning as a source of food, forests also contribute to the cultural aspects of society in the Malay civilisation. Hence, this study will analyse the image and description of the Malay forests based on the writing of British officers and writers during the colonial era such as Maxwell, Clifford, Swettenham, Fauconnier, Endicott, Winstedt, Skeat, Wilkinson and Annandale. By using a narrative approach and auto-ethnography, views of the Malay forest will be assessed from Western perspectives, which are based predominantly on the observations of British-Malaya colonial officers and Western scholars involved directly in the Malay community and their communal activities at the time. In summary, this writing will depict the worldview of the Malays about their forests, physically and spiritually, through the lens of Westerners.

Authors:   Universiti Malaysia Sabah, Tangil Jacinta , Amat Asmiaty
Published: April 2021

This study discusses the practice of the bombon system which is a tradition of the Kadazandusun community. The bombon system is a method of conservation of freshwater fish that has been practiced by the Kadazandusun since the time of their ancestors. Through this practice, the Kadazandusun community can preserve their environment, while at the same time ensuring a continuous source of fish. The bombon tradition is based on the traditional beliefs and customary laws of the Kadazandusun people. The bombon system shows the local wisdom of the Kadazandusun community towards the environment and in human relations. The problem around which this study is centred relates to the structural functionalism of the bombon system in the life of the Kadazandusun community. The objective of this study is to look at the function and role of the practice of the bombon system in the life of the Kadazandusun community. This study was conducted via field study, employing interviews, participatory observations and document research. The results show that the bombon system and the Kadazandusun community are functional and support each other’s survival. The practice of the bombon system becomes a functional aesthetic requirement for the community of bombon practitioners, furthering its role as a contributor to the values and culture of the practitioner community. The practice of the bombon system, which highlights many implicit and explicit positive effects in the life of the Kadazandusun community, proves that the practice is functional and continues to be relevant to the life of the community today.

This paper discusses about the symbol of “jantan” (male dominance) which have positive meanings, found in Malay proverbs by Tenas Effendy. This discussion uses the Framework of Malay Critiques by S. Othman Kelantan, which contains 10 principles. The underlying meanings in the “jantan” symbol will be analyzed to scrutinize the worldview of those who conceptualize these Malay proverbs as well as their association with the negative traits of male dominance. Malay proverbs that have been examined will be able to illuminate the inherent thought patterns of the Malay society, and at the same time, explore their vast knowledge of the world. Research on the Malay “Jantan” is important to analyze the lens in which was viewed by a predominantly oral society, as well as the explicit and implicit meanings of the symbols in Malay proverbs.

Hak Pemeliharaan Anak bagi Mualaf: Konflik Undang-Undang di Malaysia

In Malaysia, disputes concerning custody rights are among the frequently-debated topics in cases of conversion to Islam, if it involves a marriage previously registered under civil law. Since coming into force, a frequent issue that has arisen is the rights of convert spouses under the Law Reform (Marriage and Divorce) Act 1976 (Act 164), specifically Sections 3 and 51, as the muallaf (convert to Islam) does not have the right to petition for dissolution of marriage under this Act. However, in 2017, amendments were made to this Act to bring about better and more efficient resolutions to any legal issues arising in such matters. Therefore, this article aims to compare the concept of hadhanah (care and protection of children) in Islamic law with custody rights under Malaysian civil law. The factors that frequently give rise to conflict were analysed, as well as the implications of the 2017 amendments (Act 164) concerning the application procedure for custody rights of convert spouses. Library research was employed to collect data for content analysis. The findings show that the amendments are able to aid in resolving issues concerning divorces of converts who were previously bound to a civil marriage without the right to petition for dissolution. The amendment also allows both spouses the right to apply for custody of a child after their divorce has been finalized by the civil court. The study further recommends that in such cases, child welfare, and not the rights of the converted parent, should be the main concern at all times.

This article studies the hidden wisdom behind the pronouncement of conditional divorce, the rules and conditions prescribed by the jurists, as well as the forms and types of ta’līq in shariah law. This article also seeks to look at the practice of ta’līq in Malaysia as well as provisions under Islamic family law in Malaysia, as well as the practice direction issued by the Department of Syariah Judiciary Malaysia. The study employed library research to expound the opinions of earlier jurists from various schools of Islamic jurisprudence, and textual studies on the provisions of law related to the issue concerned. The study found that the wording of the official pronouncements of ta’līq varies from state to state, hence the consequences can also differ. The researcher is of the view that the practice of pronouncing ta’līq after the solemnization of a marriage contract should be reviewed. It needs to be said that the validation of a divorce by ta’līq is a more complicated process than an ordinary divorce.

The Malaysian government has enforced numerous consumer protection policies as a measure to provide consumers with the best consumer protection. This includes the establishment of the Tribunal for Consumer Claims Malaysia (TTPM), which was established under the Consumer Protection Act 1999. The aim was to ensure consumers receive the best protection of their rights. However, numerous issues have been highlighted, such as the TTPM’s limited jurisdiction followed by inadequate understanding of consumers concerning the role and function of TTPM as a platform for remedial claims. Aiming to address the objectives of this research, the current study employed a qualitative approach to gather information by way of interview and observation. This study finds that the TTPM plays a very important role in providing a platform for remedial claims for consumers in Malaysia. The existence of the TTPM as a medium for consumer protection should be well-exploited as it benefits consumers. However, the roles and functions of the TTPM should be further developed. Thus, it is recommended that the relevant parties take steps to improve consumer protection rights in this country, in particular involving the TTPM.
