Multi-time Scale Adequacy Evaluation of the Power System With High Penetration of Renewable Energy Sources Based on Empirical Mode Decomposition
Authors: Zhang Wenbo , Xing Haijun , Sun Yiwen , Huang Ruanming , Song Ziyu , Luo Jiayi , Bian Xiaoyan
Published: April 2023

Adequacy is a crucial consideration in the planning and operation
dispatching of the power system, especially in the power system with
high penetration of renewable energy sources. Considering the multi-time
scale characteristics of renewable energy power and the response
characteristics of flexible regulation resources, a multi-time scale
adequacy evaluation method based on empirical mode decomposition is
proposed. In this method, a net load curve is decomposed into multiple
component curves at a multi-time scale by the empirical mode
decomposition (EMD) algorithm. As a result, the adequacy demand of the
system at each time scale is obtained by waveform recognition. Moreover,
the available adequacy resources of the system at different time scales
are obtained according to the regulation models of flexible regulation
resources. By analyzing the adequacy demand and available adequacy
resources of the system at the same time scale, the adequacy evaluation
indices at each time scale can be calculated and weighted to form the
comprehensive indices. At last, taking a practical power system as a
case, the adequacy evaluation indices at each time scale with different
capacities of renewable energy sources and energy storage systems are
compared and analyzed. Simulation results indicate the validity of the
method.
Grønlands mineral- og olieefterforskningshistorie i internationalt politisk perspektiv
Authors: Getreuer Flemming
Published: April 2023

Samspil mellem råstof-, selvstændigheds- og udenrigspolitik er vigtigt i samarbejdet mellem Grønland og Danmark. Mulige indtægter fra råstofudnyttelse har tidligere været en central del af selvstændighedspolitikken i Grønland, men fokus er nu ændret mod det udenrigspolitiske. Grønland har en lang mine- og mineralefterforskningshistorie, men der er relativt få projekter, som har givet stor samfundsmæssig gevinst. Olieefterforskningshistorien har været mere sporadisk med nogle få hektiske perioder i 1970’erne og i det nye årtusinde. Aktiviteterne har haft stor international bevågenhed, både i perioden med dansk myndighed før 1979, i perioden med fælles beslutningskompetence, og nu hvor Grønland siden 2009 har haft ansvaret for lovgivning og administration. Investeringerne i henholdsvis olie- og mineralefterforskning i Grønland er af nogenlunde samme størrelsesorden, men der er meget stor forskel på den involverede industri og effekten på det grønlandske samfund. I perioder har der været interesse for strategisk vigtige råstoffer, under og efter 2. verdenskrig især kryolit og uran og i de senere år sjældne jordarter. Råstofferne indgår i et kompliceret geopolitisk spil mellem USA, EU og Kina, hvor Grønland forsøger at opnå yderligere udenrigspolitisk indflydelse i forhold til Danmark.
Abstract in EnglishGreenland mineral and petroleum exploration history in international political perspectiveGreenland has a long mining and mineral exploration history. Despite significant political interest and investments, only few projects have been economically successful. Petroleum exploration has been more sporadic with hectic activity in the 1970’ties and in the new Millenium. Costs for exploration are in the same order for minerals and petroleum exploration but with large differences in the involved industry, the national companies and the effect on Greenland society and politics. Throughout history there has always been strong political focus on resources in Greenland, both in periods with Danish authority before 1979, in the period with joint competence, and after Greenland took over full legislation and administration in 2009. Possible income from resource exploitation has always been a central part of the independence policy in Greenland but focus is changing towards foreign policy. In some periods other countries have shown interest for strategically important raw materials, especially cryolite and uranium during and after World War II, and in later years Rare Earth Elements. Greenland resources are part of a complicated geopolitical game between the US, EU, and China, and where Greenland is challenging the foreign policy of the Kingdom of Denmark and prepares for independence.

Authors: Weicai Chen
Published: April 2023

Odorrana lipuensis occurs in an entirely dark karst cave in Lipu County, Guangxi Province, China. This paper discusses the ecological habits of the type locality of O. lipuensis, including the cave environment, daily activity rhythm, annual activity pattern, food, and predators. The results show that the life cycle of O. lipuensis is completed entirely in dark caves; cave temperature fluctuates around 19℃; there is no hibernation phenomenon, and it is active throughout the year. The daily activity rhythm does not differ between day and night, and breeding seasons range from March to June. Given the limited distribution range and small population size of O. lipuensis, it is recommended for inclusion in the national second-class protection animal list.
Review and Comparative Assessment of Biacetabulum macrocephalum McCrae, 1962 (Cestoda: Caryophyllidae) from Catostomus commersoni (Lacépède) in Wisconsin, USA
Authors: Amin Omar M
Published: April 2023

Specimens of Biacetabulum macrocephalum McCrae, 1962 (Cestoda: Caryophyllidae) were first described from the white sucker, Catostomus commersoni (Lacépède) in Colorado. The white sucker appears to be its major host species in a few other states often in the Mississippi River basin. We have collected and examined this uncommon cestode, also from C. commersoni in Tichigan Lake, a tributary of the Mississippi River and from the Root River in SE Wisconsin. We update our first and only 1986 account of our Wisconsin population, with new observations and measurements, and compare with those in the original and other descriptions. The morphology of B. macrocephalum is revisited using light microscopy revealing new features. Emphasis is placed on the morphological variability of its scolex and reproductive structures especially its ovarian arms and pre- and post-ovarian vitellaria. Measurements of 10 specimens from the Root River provided an opportunity to review the taxonomy and description of the species, distinguish locality differences, and correct and update other statements and concepts by other observers. The disconnected distribution of worms from the same host species in separate waters of various states is described.

Introduction: Chronic knee pain is the leading cause of functional limitations in the older age group and accounts for many visits to health care providers. This degenerative condition is progressive with functional impairment and a severe decrease in quality of life. Pain management with Adductor Canal Block (ACB) and Genicular Nerve Block (GNB) can be an alternative treatment option for chronic knee pain. This study aims to analyze the difference between clinical & laboratory outcomes of the ACB and GNB groups.

Material & Methods: An experimental study with consecutive sampling was conducted on 34 patients with chronic knee pain divided into 2 groups of ACB and GNB procedures. The parameters measured were VAS score, pain-free duration, range of motion, and interleukin-6 (IL-6) levels.

Results: Predominance of chronic knee pain patients found in older women. Based on statistical analysis, there was an improvement in VAS scores (p<0,05), a similar pain-free duration (p>0,05), an improvement in the range of motion (p<0,05), and a decrease in IL-6 levels (p<0,05) significantly in the ACB group compared to GNB.

Conclusion: ACB can be used as an effective therapy in treating chronic knee pain.
Health Insurance & Humanoid ROBOT-Agents: A case study
Authors: Tiwari Ashu
Published: April 2023

The Sustainable Development Goal (SDG) Target 3.8 has emphasized the persistence of health risks as a major challenge for emerging and developing countries. This challenge necessitates the achievement of Universal Health Coverage (UHC) by enhancing the infrastructure of the public sector. However, relying solely on public sector healthcare may not be sufficient to meet the needs of large populations, particularly in underdeveloped regions. Consequently, private sector healthcare solutions have emerged to fill service gaps, but they remain unaffordable for many low-income individuals. To the end, Health insurance can play a crucial role in making these services more accessible and affordable, but it faces several challenges including poor accessibility, low awareness, lack of skilled workforce, and corruption.
The integration of Artificial Intelligence (AI) and Machine Learning (ML) technologies can offer solutions to these challenges. However, the adoption of technology in the insurance domain poses behavioral challenges that must be identified and addressed. This is particularly important in developing and emerging countries where markets are still underdeveloped, and information asymmetries are high. This study examines some of these challenges by studying people’s attitude towards humanoid agents. For this study a case study approach has ben used. Overall, addressing the challenges of health insurance and incorporating advanced technologies can provide a vital safety net against health risks to people.

Objetivo: analizar los componentes que determinan el mercado de huevo, identificando las principales variables determinantes de la oferta, de la demanda y de las transmisiones de precios. Metodología: se formuló un modelo de ecuaciones simultáneas con información del período 1975-2020. La estimación se realizó mediante el método de mínimos cuadrados en dos etapas, con el procedimiento SYSLIN del paquete computacional SAS (Statistical Analysis System, v.9.4.). Se tomaron en cuenta las principales variables económicas y tecnológicas que inciden en las funciones del modelo. Resultados: el modelo econométrico que representa al mercado de huevo está compuesto por cinco relaciones funcionales y una función de identidad. Se presenta una oferta inelástica (0.15) a los cambios del precio al productor y una demanda inelástica (-0.54) al precio al consumidor. El precio al productor de carne de cerdo fue un competitivo débil de la producción de huevo (-0.25). El precio al consumidor de carne de cerdo es un complementario fuerte (-1.16) y el de carne de bovino es un sustituto cercano (1.12), ambos de la cantidad demandada. Limitaciones: el período de análisis del mercado de huevo en México. Conclusiones: las variables que determinan la oferta de huevo en México son los precios al productor de huevo, cerdo, alimento balanceado y la tecnología o conversión alimenticia. La demanda de huevo en México está determinada principalmente por los precios reales al consumidor de huevo, cerdo, bovino y el ingreso real nacional disponible per cápita.

n present study, the effects of curcumin supplementation on oxidative stress and antioxidant defense system in heart tissue in adult rats were investigated. Sixteen rats (8-weeks-old) were selected and divided into two groups. The first group is the experimental group and these rats (n=8) were gavaged with curcumin, dissolved in corn oil, at a dose of 300 mg/kg per day for 28 days. The second group is the control group, rats in this group were given curcumin and equal amount of corn oil to eliminate the porter effect. Euthanasia was performed and total antioxidant capacity (TAS), total oxidant capacity (TOS), malondialdehyde (MDA) and glutathione (GSH) levels were analyzed from heart tissues. Curcumin supplementation resulted in significantly increased GSH levels(P0.05). The total antioxidant capacity (TAS) and total oxidant capacity (TOS) ratios were found to be statistically significant. In the other group supplemented with curcumin, MDA levels tended to decrease compared to the control group, and there was no statistically significant difference between the two groups. Curcumin supplementation protects the heart tissue against oxidative damage and strengthens the antioxidant defense system in adult rats.

Authors: Rey Norman , Miranda Aguirre Catalina
Published: April 2023

El ingreso de Colombia a la OTAN como socio global trae consigo retos y oportunidades para el país y sus Fuerzas Militares, que no solo dependen de la gestión del sector, sino de la voluntad política al interior del país. Este artículo busca recorrer algunos hitos históricos (especialmente estudiando los conceptos estratégicos de esta organización) que condujeron a la adaptación de la seguridad cooperativa como una herramienta para encontrar en países distantes a sus áreas de influencias más cercanas, aliados estratégicos para la consecución de sus intereses. De igual forma, este documento debela algunas oportunidades para ambas partes, pero también, hace un llamado para mitigar tempranamente los riesgos y desafíos asociados a este nuevo marco cooperativo.
Introduciendo la geopolítica de las emociones
Authors: Álvarez Calderón Carlos Enrique
Published: April 2023

Las teorías en relaciones internacionales y los estudios en Seguridad y Defensa, han dependido en el pasado de suposiciones sobre la emoción que rara vez se articulaban y que pudieron no llegar a ser del todo correctas. Por ejemplo, la teoría de la disuasión puede haber sido fundamentalmente defectuosa porque sus suposiciones y prescripciones de política no reconocían completamente las respuestas humanas razonables a la amenaza y el miedo. De manera similar, las teorías liberales de cooperación bajo anarquía y la formación de comunidades de seguridad que enfatizaban el cálculo racional de los beneficios de la comunicación y la coordinación de los actores, eran deficientes en la medida en que no incluían una consideración cuidadosa de las emociones y las relaciones emocionales.

No obstante, varios académicos de diversas corrientes teóricas están considerando en la actualidad que las relaciones entre Estados y actores no estatales están impregnadas de un significado emocional, que llevarían a plantear nuevos escenarios y desafíos para la seguridad, la ética y otras áreas de la política global.

A  decrease in high-density lipoprotein (HDL) happens in type 2 diabetes mellitus. The cytokines TNFa and IL-6 are proinflammatory cytokines that are elevated in the blood in many patients with DM. Turmeric is one of the natural ingredients with antioxidant, anti-cholesterol, and anti-inflammatory properties through its active substance, curcumin. Objective: To prove the effectiveness of the combination of metformin and turmeric extract on HDL levels, TNFa levels, and IL-6 levels in Streptozotocin-Nicotinamide-induced Wistar rats. Methods: The study used a post-test-only controlled group design. The subjects were 24 male Wistar rats which were randomly divided into four groups, namely K1, K2, P1, and P2. The whole group was a type 2 DM model induced by streptozotocin-nicotinamide. Group K2 was given metformin 45mg/KgBW/day, group P1 was given turmeric extract at a dose of 200 mg/KgBW/day, and group P2 was given a combination of metformin and turmeric extract. On day 15, blood was drawn for HDL, IL-6, and TNFa examination. The data were analyzed using the one-way Anova test. Results: The mean HDL level in the P2 group (72,4±33,31) was the highest compared to the other three groups. The lowest mean TNFa level among the four groups was the P2 group (7,56±0,44). The lowest mean levels of IL-6 were obtained in the P2 group (58,82±2,15). One-way Anova test on HDL, IL-6, and TNFa levels showed a significant difference between groups with p-value = 0.000. Conclusion: The combination of metformin and turmeric extract can increase HDL levels and reduce IL-6 levels and TNFa levels better than giving metformin or turmeric extract alone.Keywords:  turmeric extract, HDL, IL-6, TNFa
