Effizientere Regionalplanung durch das Raumordnungsverfahren?
Authors: Schubert Markus 
Published: June 2024

Das Raumordnungsverfahren (ROV) wird auch neben vorhandenen Regionalplänen von großer Bedeutung bleiben, nicht zuletzt deshalb, weil sich mit diesem bewährten und flexiblen Instrument Schwächen im gültigen System der Raumordnung und Landesplanung teilweise ausgleichen lassen. Allerdings steckt in einer intensiven Anwendung dieses Verfahrens, wie sie insbesondere in Bayern üblich ist, wo sich das Instrument in der Praxis von den Plänen und Programmen teilweise verselbständigt hat, durchaus auch die Gefahr einer Beeinträchtigung der Regionalplanung. Diese Beeinträchtigung beruht weniger auf der in der Literatur immer wieder warnend hervorgehobenen Antinomie der Instrumente Planung als Gesamtschau und ROV als Einzelfallabstimmung. Das Problem ist vielmehr die verwaltungsorganisatorische Trennung dieser beiden Instrumente, wie sie mehr oder weniger in allen Bundesländern üblich ist, die das ROV anwenden. Dadurch wird die Institution Regionalplanung bzw. Regionaler Planungsverband gezwungen, Entscheidungsbefugnisse an die mit der Durchführung des ROV betrauten Landesplanungsbehörden abzugeben. Um die weitgehend unbestrittenen Vorzüge des ROV weiterhin oder (durch Fortentwicklung des Instruments) zunehmend ausnutzen zu können, ohne daß dies – wie bisher – auf Kosten der Institution Regionalplanung geht, sollte dieses Instrument in die Hände der Regionalen Planungsverbände bzw. der sonst für die Regionalplanung zuständigen Stellen gelegt werden. Damit würde die Regionalplanung als Institution vorteilhaft gestärkt und der in letzter Zeit zunehmend laut gewordenen Forderung Rechnung getragen, die Raumordnungspolitik insgesamt zu dezentralisieren.

Abstract
Adjacent mountain area and plain area generally belong to the same climate zone, and a close hydraulic connection is also found between them. However, the flood controls in these two areas belong to different management departments. Flood occurring in these two areas can bring serious waterlog disasters, posing great threat to human lives and property. Previous studies mainly focused on the individual flood event in mountain or plain areas, while the research on the floods simultaneously occurring in both areas is insufficient. Hence, this study establishes a copula function-based assessment method to systematically analyze the characteristics of simultaneously-occurring floods in mountain and plain areas in Hangzhou City, thereby providing a basis for the collaborative management of floods in both areas. Results show that the proposed approach can give water level combinations in mountain and plain areas that are prone to co-occurring floods. Moreover, the water level in plain area is most likely to simultaneously appear with the water level in mountain areas under similar return periods, indicating that floods of equivalent level are likely to occur in plain areas when severe floods occur in mountain areas. This study provides a better understanding on the interplay of floods simultaneously occurring in mountain and plain areas, offering insights for coordinating the flood protection system in these two areas.

German Idealism, Marxism, and Lukács’ Concept of Dialectical Ontology
Authors: Thompson Michael J. 
Published: June 2024

Abstract
I explore the roots of ontological thinking in the late thought of Georg Lukács via the development of the nature of praxis in German Idealism and the thought of Marx. I contend that the thesis of spontaneous, self-creation as well as social relatedness are both core themes in German Idealism that achieve definitive form in Marx’s thought. In effect, I argue that the human capacities for relatedness and the formation of relations with others paired with the teleological structure of human practical agency constitute a crucial ontological ground for critical theory. It is this that Lukács focuses on in his later ontological writings and which can be used to re-orient contemporary critical theory and critical philosophy which has been dominated by post-metaphysical and neo-Idealist currents in recent decades.

Abstract
Ramirez, VJ, Bazrgari, B, Spencer, A, Gao, F, and Samaan, MA. Influence of repetitions-to-failure deadlift on lumbo-pelvic coordination, with and without body armor. J Strength Cond Res 38(10): 1732–1738, 2024—Repetition-to-failure (RTF) deadlift is a training modality for building lifting capacity that is often implemented by service members to maintain a minimum level of physical fitness. Despite its physiological benefits, little is known about the effects of RTF on the biomechanics of lumbar spine. Additionally, the effects of heavy deadlift training with body armor are unknown. The aim of this study was to investigate the effects of RTF deadlift on lumbo-pelvic coordination and posture, with and without body armor. Twenty-three healthy subjects, recreational powerlifters, were recruited for this study. Kinematics of the trunk and pelvis were measured using a 3D motion capture system while subjects conducted RTF deadlifts with a 68-kg low-handle hexagonal bar with and without a simulated body armor (22.68 kg). Lumbo-pelvic coordination was characterized using a vector coding approach and coupling angle variability (CAV) using circular statistics, over 3 equally divided segments of the lifting phase. More specifically, the coupling angle values were used to determine the coordination pattern between the thorax and pelvis. Trunk and pelvis ranges of motion and the amount of in-phase lumbo-pelvic coordination pattern increased with RTF deadlift. Additionally, CAV of the first and the third segments of deadlift cycle increased with RTF deadlift. Increase in variability of lumbo-pelvic coordination and peak trunk flexion (i.e., indication of increased mechanical demand of lifting on the spine), as a result of RTF deadlifting, can have deleterious soft tissue responses and contribute to an increase in risk of lower back injury.

High consumption of cooking oil has an impact on the availability of used cooking oil. Used cooking oil can cause pollution if the processing is not sound. So we need an alternative as a solution for handling cooking oil waste. Adsorption using avocado seed adsorbent is the choice because the morphological structure and other characteristics meet the specifications for the adsorption of used cooking oil. This study aimed to determine the acid number, viscosity, density and isothermal adsorption from avocado seeds as an adsorbent in used cooking oil. The method used was by varying the adsorbent doses of 100, 200 and 300 mg L-1 with contact times of 30, 60, 90, 120 and 150 minutes. Adsorption was carried out at a temperature of 70oC and a stirring speed of 200 rpm. The results obtained for the acid numbers at various adsorbent doses at 150 minutes reached 6.22, 4.98 and 3.12 mg KOH g-1. Viscosity at different adsorbents reached 54.2, 46.23 and 45.44 mm2 s-1, while the density reached 898.92, 897.17 and 896.55 kg m-3. Langmuir isothermal adsorption obtained R2 value in the equation reached 0.9365 and Freundlich reached 0.9496, so the Freundlich equation model is more recommended for use in the adsorption process because the regression value is close to 1.

Textile liquid waste is pollution resulted from textile industry activities that often produce hazardous and toxic materials. Therefore, appropriate processing techniques are needed. There are many processing methods that can be used in treating this textile liquid waste, one of which is using membrane technology with phase inversion techniques. Membrane technology has advantages over other processing methods such as, being biopolymeric, relatively lower energy consumption, does not use chemicals in the processing process, and does not cause new waste in the processing process. In this study, 3 variations of cellulose acetate propionate (CAP) concentration were carried out in the manufacture of membranes including, 13% CAP; 14% CAP; and 15% CAP. Membranes that have been made are then carried out several analyses, namely porosity analysis; flux analysis; rejection analysis; and color concentration reduction analysis. The results in this study found that the highest porosity value, rejection value and flux value were found in the CAP membrane with a concentration of 13%. The CAP membrane has the best rejection value on reducing the remazol concentration of 43% with a membrane of 13% CAP.

The Katuk plant (Sauropus androgynus L. Merr) is a natural substance with proven efficacy in treating diabetes, obesity, and inflammation. It also possesses antioxidant, lactation-inducing, and antibacterial properties. This study aimed to investigate the impact of varying concentrations of katuk leaf extract on characteristics of the moisturizer cream produced. The study involved extracting katuk leaves using the maceration method for 24 hours, utilizing ethanol as the solvent. The extraction process resulted in a yield of 1.86%. The final yield contains alkaloid chemicals, flavonoids, terpenoids, saponins, and tannins. The formulations employed in this investigation utilized the codes F0, F1, F2, and F3, representing the content of katuk leaf extract at 0%, 2%, 4%, and 6%, respectively. The cream generated exhibited an identifiable aroma of katuk and had a hue ranging from light green to blackish brown, as determined by organoleptic testing. The pH values of specimens F0, F1, F2, and F3 were 7, 7, 7, and 8, respectively. The spread ability measurements for specimens F0, F1, F2, and F3 were 5.3 cm, 5.5 cm, 6 cm, and 6.1 cm, respectively. According to the findings of this investigation, specimens F0, F1, F2, and F3 adhered for 5 seconds, 4 seconds, 4 seconds, and 5 seconds, respectively. The formulation F2 is the most superior product generated in this investigation. This is because this specimen exhibits the highest level of respondent satisfaction compared to the other specimens. This formulation exhibits antioxidant activity with a per cent inhibition of 30.51% and an IC50 value of 84.63 ppm. The face moisturizing cream derived from katuk leaf extract possesses a high antioxidant potency, placing it in the active/strong category.

Aim. To evaluate the effectiveness of laparoscopic surgeries for diseases and malformations of the pancreas in children. Materials and methods. 53 laparoscopies were performed from 2005 to 2023. Enucleation was performed in 16 children, distal resection of the pancreas with spleen preservation – in 16, corpo-caudal resection of the pancreas – in 4, subtotal resection of the pancreas – in 9, central resection of the pancreas – in 5, head resection with duodenal preservation – in 1, pancreaticoduodenal resection with pyloric preservation – in 2 children. The age of the children ranged from 2 months to 17 years. Results. All surgeries have achieved the intended clinical effect. The average time of enucleation accounted for 88.1 ± 47.7 min., distal resection with spleen preservation – 100.3 ± 21 min., corpo-caudal resection – 113.3 ± 28.9min., subtotal resection – 101 ± 21.7 min., central resection – 243.3 ± 81.1 min., head resection with duodenal preservation – 235 min., pancreaticoduodenal resection with pyloric preservation – laparoscopic and laparoscopically assisted – 435 and 415 min. Intraoperative bleeding was noted in 6 cases (11.3 %), in 2 (3.8 %) conversion was performed in 2 cases (3.8 %). The postoperative period revealed 6 (13.2 %) early and 8 (15.1 %) late complications. No fatal outcomes reported. The follow-up ranged from 1 to 10 years, no recurrences reported. Conclusion. Focal pancreatic lesions in children refer to heterogeneous diseases and malformations requiring various resection interventions. Laparoscopic enucleation and distal resection of the pancreas are considered as the most effective. Further clinical experience is required to explore the feasibility of using laparoscopy in children to perform central resection of the pancreas and pancreaticoduodenectomy.

Published: June 2024

The absorption of nitrogen from urea fertilizer is significantly inefficient. Due to its solubility in water. This problem can be overcome by producing slow-release fertilizer (SRF) that inhibits urea from being dissolved in water. Sulfur-coated urea (SCU) is one of the SRF methods. Therefore, this study aimed sulfur-coated slow-release urea fertilizer using sulfur waste from the Biological Sulfur Recovery Unit (BSRU) in Field X. A total of 14 tons of sulfur cake was produced daily by BSRU in Field X and sent to the laboratory for composition analysis, followed by drying. Subsequently, the dried sulfur was into a powder using a hammer and sieved to achieve a size of 200 mesh. Based on the results, SCU with the sulfur to urea ratio of 1:1 and mixing time of 15 minutes exhibited the best performance in dissolution tests with the longest dissolution time of 5 minutes which was better compared to the uncoated urea. After 7 days of observation, spinach that received SCU was more fertile and greener. The calculated NPV and payout time were 88712 million IDR and 1.76 years, respectively. This indicated that the development of this study was economically attractive. In conclusion, the value of sulfur waste from gas processing was increased by using sulfur waste from BSRU as a coating of urea while reducing related environmental effects.

Existe literatura científica que muestra el impacto del proyecto educativo de ‘Comunidades de Aprendizaje’ (CdA) en el desarrollo de competencias sociopersonales y en una mejor y mayor trayectoria académica en colectivos vulnerables pertenecientes al pueblo gitano. Un amplio campo de la literatura señala la correlación de estos factores con el aumento de la empleabilidad. Sin embargo, existe poca investigación que analice los resultados de las CdA en el aumento de la empleabilidad de las personas gitanas participantes. Esta investigación, a través de un estudio de caso único, identifica el impacto de una CdA, donde el 88% de sus miembros pertenece al colectivo gitano en situación de desigualdad social, en el aumento de su empleabilidad. Para llevar a cabo este análisis se utilizó una metodología de enfoque comunicativo. Las técnicas de investigación aplicadas fueron 6 relatos comunicativos a 3 mujeres y 3 hombres pertenecientes a comunidad gitana en riesgo de exclusión y 2 grupos de discusión dialógica a 5 profesionales de la escuela. Tomando como referencia indicadores de empleabilidad recogidos en la literatura científica, los datos muestran en qué medida el proyecto está mejorando la empleabilidad en estas 6 personas gitanas y qué actuaciones tienen mayor incidencia en dicho impacto.

Verification of pathomorphological diagnosis is a key stage in selection of treatment tactics in patients with neoplasms. Understanding of the nature of pathological process is especially important in context of primary tumors of the bones, soft tissues and metastases as despite active development of diagnostic techniques, they do not allow to obtain full information on histological nature of the tissues, differentiation grade, as well as molecular and genetic characteristics of the tumor. These data are associated with selection of optimal treatment tactics at every stage and disease prognosis. The optimal approach to obtaining histological materials in tumor of the bones and soft tissues are radiologically guided (X-ray, computed tomography and magnetic resonance imaging) trephine biopsy or ultra-sound-guided core biopsy.Aim. To determine information value of trephine and core biopsies of neoplasms of the bones and soft tissues of various locations, identify mistakes during manipulation affecting results of morphological diagnosis.Materials and methods. Between 2015 and 2023 at the Russian Scientific Center of Roentgenoradiology, 788 patients aged 18–85 years (380 men, 408 women) underwent 602 trephine biopsies and 248 core biopsies (n = 850) of neo-plasms of the soft tissues and bones of various locations. Absence of informational value of morphological study required repeat trephine biopsies in 19 patients, core biopsies in 2 patients, open biopsies in 13 patients.Results. Informational value of trephine biopsy of the bones was 90.5 % (long bones – 96.8 %, flat bones – 91.6 %, spine bones – 82.1 %), core biopsy of the soft tissues 98.8 %. Sufficient amount of material for immunohistochemical testing was obtained in 89 % biopsies. Interventions in cases of bone neoplasms were performed using CT (computed tomography) navigation; for core biopsies of the soft tissues, ultrasound was used. Absence of informational value in trephine bio psies was caused by insufficient amount of material (48 (7.97 %) cases), retrieval of trephine biopsy from the area of tumor necrosis (4 (0.67 %) cases), incorrect selection of access (4 (0.67 %) cases) and needle type (1 (0.17 %) case).Conclusion. Results of analysis of trephine and core biopsy data of bone and soft tissue neoplasms showed high information value, which is supported by literature data. This allows to consider these methods of histological material retrieval the “golden standard” of bone and soft tissue tumor diagnosis.
