Published: October 2022

Abstract. The optimal control problem for flight trajectories of Fly-Gen airborne wind energy systems (AWESs) is a crucial research topic for the field, as suboptimal paths can lead to a drastic reduction in power production. One of the novelties of the present work is the expression of the optimal control problem in the frequency domain through a harmonic balance formulation. This allows the potential reduction of the problem size by solving only for the main harmonics and allows the implicit imposition of periodicity of the solution. The trajectory is described by the Fourier coefficients of the dynamics (elevation and azimuth angles) and of the control inputs (onboard wind turbine thrust and AWES roll angle). To isolate the effects of each physical phenomenon, optimal trajectories are presented with an increasing level of physical representation from the most idealized case: (i) if the mean thrust power (mechanical power linked to the dynamics) is considered as the objective function, optimal trajectories are characterized by a constant AWES velocity over the loop and a circular shape. This is done by converting all the gravitational potential energy into electrical energy. At low wind speed, onboard wind turbines are then used as propellers in the ascendant part of the loop; (ii) if the mean shaft power (mechanical power after momentum losses) is the objective function, a part of the potential energy is converted into kinetic and the rest into electrical energy. Therefore, the AWES velocity fluctuates over the loop; (iii) if the mean electrical power is considered as the objective function, the onboard wind turbines are never used as propellers because of the power conversion efficiency. Optimal trajectories for case (ii) and (iii) have a circular shape squashed along the vertical direction. The optimal control inputs can be generally modeled with one harmonic for the onboard wind turbine thrust and two for AWES roll angle without a significant loss of power, demonstrating that the absence of high-frequency control is not detrimental to the power generated by Fly-Gen AWESs.

Authors: Rahman Md. Moksedur , Habib Md. Ahsan , Shah Md. Saifuddin 
Published: October 2022

Information on artificial breeding of Cirrhinus reba and Labeo bata is not common in Bangladesh. There are reports on serious decline of natural abundance of these species and are considered threatened under present environmental situation. The species should be brought under culture systems to protect them from being dwindled. For optimizing the breeding technique, the experiment was conducted. Nine pairs of male and female of each species were used. The females of both the species were divided into three treatment groups (T1, T2 and T3). Weight of reba female and male ranged from 110 to 140g and 80 to 105g respectively, the same for bata ranged from 310 to 388g and 180 to 260g for female and male respectively. The females of C. reba were injected a first dose of 0.5, 1.0 and 1.5 mg PG kg-1 body weight followed by a second dose of 4.0, 4.5 and 5.0 mg PG kg-1 body weight respectively after 6 hours of the first dose. The doses for L. bata were 0.5, 1.0 and 1.5 mg PG kg-1 body weight as first, followed by a second dose of 4.5, 5.0 and 5.5 mg PG kg-1 body weight. A single dose for males of C. reba was 1.5 mg PG kg-1 body weight and for L. bata 2.0 mg PG kg-1 body weight. Single pair mating was performed under semi-natural conditions in nine separate hapas with continuous showering at a temperature range of 27-28 0C. The highest average fertilization and hatching of C. reba were obtained at 87.88% and 81.47% respectively and that of L. bata were 86.19% and 75.00% respectively from T2.The percentage of fertilization and hatching obtained against the comparatively low doses of hormone in this experiment was considered noteworthy.

Published: October 2022

A 95 days experiment was conducted to observe the growth performance of giant fresh water prawn (Macrobrachium rosenbergii) replacing fishmeal protein by dietary soybean meal protein in ten earthen mini ponds (50 m2), at Khulna University campus . Five experimental diets containing 25% protein as Control, Diet 1, Diet 2, Diet 3 and Diet 4 were used. In Control, 36% fishmeal was used as a sole source of protein and Diet 1, 2, 3 and 4 were prepared by substituting fishmeal protein with 30, 40, 50, and 80% fishmeal protein with soybean meal protein respectively. Juvenile shrimps were collected from local vendors having 1.7 g average weight and stocked at a density of 3 m-2. Water and soil quality was monitored regularly and found within the acceptable range. The prawns were fed twice daily at satiations by serving the diets in feeding trays. The highest average weight gain was found in Diet 4 (23.89 ± 5.29 g) and the lowest in Diet 2 (17.68 ± 1.09), although no significant difference (p>0.05) was observed among the treatment and the lowest FCR (1.09) the highest SGR (2.60) and PER (3.43) was achieved in Diet 4 that showed significant difference (p<0.05) with that of Control. Survival rate in Control, D1, D2, D3 and D4 was found 71%, 83%, 95%, 95% and 86% respectively. Among all treatments the better growth performance was found in Diet 4.
DESIGN AND INVESTIGATION OF THREE-DIMENSIONAL POLARIZATION-INDEPENDENT POLYMER MACH-ZEHNDER INTERFEROMETERS AT 1550 NM

We propose a Mach-Zehnder interferometer (MZI) which consists of a taper, a bending waveguide, and two symmetrical arms. The structure is realized with organic-inorganic hybrid polymer materials and analyzed by a commercially available RSoft CAD BeamPROP solver. We set the core width for input and output of the Mach-Zehnder interferometer at 6 µm for single-mode propagation. This interferometer shows an excess loss of 0.162 dB and has an efficiency of almost 96.4%. We also investigate the polarization dependency of this interferometer varying the beam incident angles from 0-30 degrees and this investigation suggests that this MZI shows polarization dependency when the light incident on the launched side of this MZI at for transverse electric (TE) and transverse magnetic (TM) modes.
Cross-Border Insolvency and the 2022 Australia-India Comprehensive Economic Cooperation Agreement
Authors: Walters Robert 
Published: October 2022

Since 2020, the world has been plunged into uncertain times. The world economy was significantly affected by the outbreak of the coronavirus disease of 2019 (COVID-19), which rapidly evolved and was quickly declared a global pandemic. As conflict in Eastern Europe raged from the beginning of 2022, the pandemic being far from over and inflation gripping the world economy, the financial stress individuals and entities were experiencing continued to escalate. At the time Australia and India signed the Comprehensive Economic Cooperation Agreement (AI-CECA) in April 2022. The signing of this economic partnership is a major step forward for both countries. The proposed economic benefits for both nation states are estimated to be significant, and will extend across many sectors including agriculture, financial services, science and innovation. This article will examine the AI-CECA and make the case that cross-border insolvency cooperation must be an ongoing priority for both countries to ensure strong economic management, and inserted into future amendment of this agreement. Problematic though is the fact that the current approach taken by Australia and India varies greatly. This article will also examine the United Nations Commission on International Trade Law , Cross-Border Insolvency Model Law, in the context of Australia and India.

The primacy of Union law over incompatible national measures: Beyond disapplication and towards a remedy of nullity?
Authors: Dougan Michael 
Published: October 2022

Recent ECJ case law suggests that there are exceptional circumstances when the principle of primacy should not merely require the disapplication of national rules that are incompatible with directly effective Union acts, but in fact obliges the domestic courts to regard certain incompatible national measures as null and void. It is argued that these developments are evolutionary rather than revolutionary: as a matter of constitutional principle, it does not fall outside the established framework governing Union-Member State legal relations, for the principle of primacy to extend its legal effects beyond mere disapplication. However, the relevant case law offers little clear guidance about precisely when an incompatibility with directly effective Union law should oblige the national court to treat a given domestic measure as non-existent. The rulings address very different legal and factual situations, and while it is possible to suggest certain common characteristics or criteria, it must still be left to future case law to determine how far a remedy of nullity should supplement or even displace the traditional expectation of disapplication.

Reforming Investment Protection: A Comparative Analysis of the EU and China
Authors: A. Barr Noah 
Published: October 2022

This article provides a comparative analysis of the European Union’s (EU’s) and China’s approaches to international investment law reform. While the EU has been referred to as a ‘systemic reformer’, which promotes significant institutional reform, China’s emerging model of investment protection remains unclassified. In the first part, this article describes the progressive emergence of China’s investment law regime. It argues that the Chinese model of investment protection may be viewed as an outright tool of foreign economic policy. Accordingly, China’s reform’s approach is a middle ground between systemic and incremental reforms. By contrast, due to its democratic nature, the EU has adopted a value-driven model. In this respect, this article posits that the political science scholarship on democracy may shed a different light on the EU’s institutional approach, and thus enrich the debate on investment law reform. The second part analyses the proposed Comprehensive Agreement on Investment (Proposed CAI) between the EU and China, which has been signed but not ratified. After showing that convergence was achieved on substantive protection, it argues that democratic imperatives explain the EU’s preference for a court system. Nevertheless, non-democracies often do not face the same incentives, which may generate disagreements regarding the dispute settlement design for investment claims.

Accountability for the Misuse of Provided Weapons in the Framework of the New European Peace Facility
Authors: Rutigliano Stefania 
Published: October 2022

The European Peace Facility (EPF) is a new mechanism officially established to allow the EU to directly assist partners in military and defence matters. After the Russian Federation’s invasion of Ukraine, the Council of European Union adopted assistance measures under the EPF financing equipment and supplies for the Ukrainian armed forces, including, for the first time, the provision of lethal equipment. This article firstly presents the legality and compliance of this provision with the law of neutrality under international law on the assumption that providing military support to a state unlawfully attacked might represent a mitigating circumstance – considering the inherent right to self-defence – and a collective countermeasure in response to severe violations of collective obligations. Then, the article discusses international responsibilities arising in case of violations of international law committed with EU-provided weapons: not only Ukraine would be liable, but also the EU and its Member States (MS) could be co-responsible for not having adequately assessed the misuse of the weapons or their diversion. Indeed, the accountability framework would appear tripartite and divided between Ukraine, the recipient state, the EU, the formal sender, and its Member States, who fund the assistance measure through an off-budget fund.

Rethinking Coexistence Between Prior Trademarks and Later Geographical Indications
Authors: Wang Xiaoyan , Song Xinzhe 
Published: October 2022

The coexistence principle presents a means for resolving the conflict between prior trademarks and later geographical indications (GIs). This principle has been increasingly adopted in several countries due to recent negotiation efforts of the EU that are meant to combat the ‘first in time, first in right’ (‘FITFIR’) principle promoted by the US. This article focuses on three controversial issues raised in the application of the coexistence principle. The World Trade Organization (WTO) Panel Reports in the Australia-EU (DS290) and US-EU (DS174) disputes related to EU Regulation 2081/92 mentioned these issues but left them unresolved, thereby making space for the EU to require trade partners to widen the scope of coexistence between prior trademarks and later GIs in a manner that runs counter to the WTO Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS Agreement). Furthermore, these unresolved issues led to difficulties in applying the coexistence principle and EU-type coexistence clause adopted in non-EU WTO Members. Based on the findings, this article recommends appropriate methods for implementing the coexistence principle that are consistent with the TRIPS Agreement.
