Authors: العزير د.عبدالكريم علي صالح
Published: May 2024

تعتبر قضية التقسيم الإداري لليمن من المسائل الحساسة والمثيرة للجدل، وقد زادت حدتها مع تبني مؤتمر الحوار الوطني مشروع التقسيم الفيدرالي. يهدف هذا البحث إلى استعراض المتطلبات الضرورية لتقسيم إداري سليم يحقق الأهداف التنموية والسياسية والاجتماعية. يتناول البحث السلبيات التي نتجت عن عدم مراعاة المعايير القانونية والدستورية، مما يؤدي إلى استغلال القضية من قبل أطراف الصراع الداخلي والتدخلات الإقليمية والدولية. يتمثل الحل في تقديم مقترحات لمعالجة هذه السلبيات، مثل تدوير المناصب السياسية العليا بين الأقاليم لضمان عدم استئثار منطقة بالسلطة، مما يسهم في تحقيق الاستقرار السياسي والاجتماعي والإداري والأمني. يختتم البحث بتقديم النتائج والتوصيات التي تعزز الحاجة للتفكير الشامل والدقيق في عملية التقسيم الإداري لضمان تحقيق الاستقرار والتنمية في اليمن.
Subject-verb agreement in Arabic
Authors: Al-Shoaibi Muthanna M. Mokbel
Published: May 2024

Agreement in grammar refers to formal relationship between elements, whereby a form of one word conforms to   the form of another. The preservation of agreement between a controlling phrase and a controlled phrase under various conditions provides a clear indication that agreement relations are sensitive to linear or directional properties, otherwise, we would expect agreement to be affected by word order changes.      In this paper I shall work on subject-verb agreement in Modern Standard Arabic (MSA) whose rich inflectional agreement system is fascinating. I intend to examine its rich agreement patterns in the minimalist framework and find out the structural mechanism of the assignment system followed by a detailed study of the three phi- features in Arabic, i.e. person, number, and gender.      This paper will address the following issues of subject-verb agreement in Arabic: a) why the verb in VSO order does not show the person and number agreement and only shows gender agreement with the post-verbal subject and b) the ambiguity of the first person in Arabic that is unspecified.

Published: May 2024

The development of the term "gig economy" is an alternative for workers amid economic instability where the basis of work is based on market demand. The gig economy system is characterized as freelancers or independent contractors who have short-term working relationships with a number of clients in return for a wage determined according to the task or amount of work. The purpose of this study is to explain and assess how elements such as religiosity, compensation, and work rights protection affect the productivity of the "gig economy" workforce in the ride-hailing services PT Gojek Indonesia. The object of this study, 122 GoJek drivers in Jabodetabek were surveyed quantitatively using the structural equation modeling method (SEM-PLS). The result of this study indicates that the factors of religiosity, compensation, work rights protection have a significant effect on the productivity of the "gig economy" workforce in ride-hailing services. The compensation factor is the most important one.
Takaful and Insurance Efficiency Determinants: Pre and Post Covid-19	Pandemic
Authors: Parizi Ahmat , Riani Ririn
Published: May 2024

This study aims to compare the efficiency of the performance of sharia insurance companies (full fledge) and conventional insurance operating in Indonesia using two stages of data envelopment analysis (DEA) for the period before and during Covid-19 (2018 - 2021). The first stage is to measure efficiency using the non-parametric DEA approach and the second stage uses the Tobit Regression model to see the factors that affect the efficiency level of insurance companies during the period of Covid-19. This result indicates the average efficiency score of Sharia and conventional insurance fluctuated, especially in 2020 there was a decline in efficiency scores, and it is evidence that Covid-19 has had little effect on the insurance business, both conventional and sharia insurance. However, this study reveals that the average conventional insurance can adjust to these conditions faster than the average sharia insurance. The effect on the efficiency level of the insurance companies can be seen from internal and external factors. The findings in this study indicate that insurance efficiency is more influenced by internal variables such as SIZE, ROA and NPM than external variables. There was no significant change in insurance efficiency during the Covid-19 pandemic.

Una visión integral del manejo de la hepatitis C y el objetivo de erradicarla
Authors: Restrepo-Gutiérrez Juan Carlos
Published: May 2024

La hepatitis C es una enfermedad viral causada por el virus de la hepatitis C (VHC), que fue identificada por primera vez en 1989 por un equipo de científicos liderado por Michael Houghton en Chiron Corporation. Esta forma de hepatitis era conocida como “hepatitis no-A no-B”, ya que no se podía identificar el agente infeccioso responsable. Puede afectar a personas de diferentes géneros y orientaciones sexuales, incluidos los hombres que tienen sexo con hombres (HSH); y su transmisión ocurre a través de situaciones en las que hay un intercambio de sangre, como el uso compartido de agujas o equipo para la inyección de drogas, o durante prácticas sexuales que pueden causar microlesiones en la mucosa anal. Es importante destacar que la hepatitis C también puede transmitirse a través de otras vías, como la transfusión de sangre no segura, la exposición a instrumentos médicos contaminados, o el compartir objetos personales que puedan tener sangre infectada.

Authors: Maharani Gita Ayu , Silvia Atikah , Dwiandini Afifah
Published: May 2024

Brainstorming is a broadly used approach across various fields, including the creative industry, to facilitate the process of ideation. As technology advances, video conference is often used to facilitate virtual brainstorming, particularly in the creative field of advertising agencies. The media compensation theory (Hantula et al., 2011) was used as a tool to investigate the use of media in the brainstorming process in order to examine how video conferencing facilitates brainstorming activities within the production division of advertising agencies. Data was collected via interview and direct observation during the brainstorming process. The findings suggest that video conference facilitates the brainstorming process by two main categories of utilization: technological utilization and communicative utilization. Moreover, it was discovered that videoconferencing is not able to facilitate brainstorming for a long period of time as it causes fatigue for team members and cannot fully replace face-to-face communication in the brainstorming process. This study supports the adaptation aspect of media compensation theory within the context of brainstorming in advertising agencies.

Published: May 2024

Wage based on unit of output is a wage paid based on the production or quantity of goods produced by the worker, in this research, the amount of batik produced by the batik maker. This study aims to determine the implementation of piece-rate wages for batik workers, Pekalongan (Batang) area in Central Java and Cirebon, West Java to see the welfare of batik workers. This research uses qualitative methods with data collection instruments in the form of interviews and field observations. The magnitude of the poverty line and the average monthly per capita expenditure of the community at the provincial and city levels are indicators in determining the welfare level of workers. The results show that the piece-rate wages received by batik workers are higher than the city and provincial poverty lines, but still low when compared to the average monthly per capita expenditure at the provincial and city levels. Nevertheless, employers can determine the amount of wages below the government's decision if employers and workers have agreed. In conclusion, the wages received by the batik workers have not been able to fulfill the KHL of the batik workers optimally. However, batik makers are considered prosperous because they have fulfilled Article 36 Paragraph (2) of Government Regulation No. 36 of 2021 where wages in Small and Medium Enterprises, especially batik, have fulfilled at least 50% of the average consumption of the provincial community and at least 25% above the poverty line at the provincial level.

El presente estudio tiene como objetivo evaluar el comportamiento agronómico del cultivo de haba manaba frente a diferentes densidades de siembra en el cantón Quinindé, Ecuador, con el fin de proporcionar recomendaciones prácticas para los agricultores y contribuir al desarrollo del sector agrícola de la zona. Se utilizó una metodología cualitativa y cuantitativa, observando y recopilando datos en dos densidades de siembra (T1 y T2) con parcelas de 50 plantas cada una, de las que se tomaron datos de 20 plantas. Se realizaron mediciones de variables como el número de hojas, altura de la planta, diámetro del tallo y producción por hectárea. El tratamiento T2, con una mayor distancia entre plantas, mostró un mejor desempeño en términos de número de hojas, altura de la planta, diámetro del tallo y producción por hectárea en comparación con T1. Aunque la diferencia en la producción no fue significativa, T2 mostró una producción ligeramente mayor de manera consistente. Los resultados sugieren que ajustar la densidad de siembra puede influir en el rendimiento y la rentabilidad del cultivo de haba manaba en Quinindé. Se recomienda considerar una densidad de siembra similar a T2 para obtener un mejor rendimiento y desarrollo de las plantas. Estos hallazgos contribuyen al conocimiento sobre la optimización de la producción agrícola en la región y destacan la importancia de la investigación para el desarrollo sostenible del sector agrícola.

Analysis of electrodialysis as a method of producing potable water
Authors: Shen Angel , Munoz Julie
Published: May 2024

Only 1 percent of the water on Earth is available for human consumption and usage, and scientists predict that this severe shortage will affect the entire planet by 2050. To resolve this problem, we collected samples of ionized seawater from along the coasts of the San Pedro Channel and Santa Monica Bay and measured their respective total dissolved solids (TDS) every hour as it underwent electrodialysis until the measurement was under the acceptable TDS for drinking water. Our objective was to produce large amounts of purified water through the separation process of electrodialysis, which if successful, would be advantageous to improving the water shortage crisis. Our hypothesis was that after saltwater undergoes electrodialysis, the time it takes for the Na+ cations to pass through the cathode exchange membranes and Cl- anions to pass through the anode exchange membranes will decrease as the voltage from the Direct Current (DC) power circuit is increased, which in turn increases the electric current. Our experimentation showed that the final recordings of the deionized water’s TDS were under the acceptable TDS for consumable water for all experiment trials. The results of this experiment may be beneficial in increasing the percentage of water available for human consumption.
Enhancing the quantum efficiency of a silicon solar cell using one dimensional thin film interferometry
Authors: Ahuja Harsh , Chacko Vinod
Published: May 2024

Crystalline silicon solar cells are prominent renewable energy sources that convert solar energy into electrical energy without emitting greenhouse gases. They are used to energize satellites as well as provide electricity for buildings, local areas/settlements, and remote locations. However, the efficiency of these solar cells is limited by two factors: light reflection at the Si-Air interface, which reduces energy absorption, and the recombination rate of electron-hole pairs that reduces the mobile charge carriers available for electricity conduction. Solar cell expenses are comparable to conventional energy resources, motivating research to increase solar cell efficiency for commercial viability. The goal of our study was to increase crystalline solar cell efficiency theoretically by simulation. We mathematically simulated an omni-directional reflector with alternate Si/SiO2 layers using multi-layered thin film interferometry in MATLAB, which was designed to reflect wavelengths in the range of 628 nm to 808 nm. We found that the ODR’s energy reflected more energy at a central wavelength of 800 nm and 8 total layers. We also simulated an anti-reflection coating layer for the top of the solar cell using alternate ZnO-SiO2 multilayers for enhanced transmission in the range of 481 nm to 2000 nm to increase solar cell efficiency for various optoelectronic devices and thermo-photovoltaic applications. We found that this reduced the reflectivity of the Si-Air interface by 49%.

Published: May 2024

The subject of research in this paper is the impact of the crisis in Ukraine on the volatility of the ruble and oil, as well as the correlation of these values with each other. In order to investigate the impact of the crisis in Ukraine as an external shock on the volatility of the ruble and crude oil, changes in the ratio of their values were analyzed on a daily basis, in the observed period during 2022 and the first four months of 2023. The analysis of time series, and then the comparative analysis of the mentioned data and the use of the GARCH model determined a certain divergence in the very nature of the behavior and movement of the ruble and oil immediately before the beginning and during the crisis in Ukraine, during the observed period. There is no doubt that the Russian currency and crude oil markets behaved much more volatile in this period, which implies a significantly greater impact on economic activities, bearing in mind the instability of the value of the ruble and oil as significant factors affecting the overall economic trends in the world.

Novosti v patogenezi in obravnavi bolnikov s sindromom takotsubo
Authors: Jovanović Mark , Poglajen Gregor
Published: May 2024

V zadnjih 30 letih od prvega opisa v strokovni literaturi je sindrom takotsubo postal prepoznavna in uveljavljena klinična entiteta. Podatki kažejo, da znaša prevalenca bolnikov s sindromom takotsubo približno 1–3 % vseh bolnikov z elevacijami spojnice ST in simptomi, ki posnemajo akutni koronarni sindrom. Hkrati približno 4 % bolnikov po akutni fazi sindroma takotsubo vsaj enkrat ponovno zboli za to boleznijo. Gre za vrsto akutnega srčnega popuščanja neishemične etiologije s sorazmerno hitrim okrevanjem krčljivosti miokarda. Sindrom pogosto sproži močan stresni dogodek, ali fizični (npr. sepsa) oz. psihični (npr. izguba bližnjega), pri približno tretjini bolnikov pa jasnega sprožilnega dogodka ne uspemo zanesljivo opredeliti. Glede na klinični potek v akutni fazi bolezni bolnike s sindromom takotsubo delimo v 2 podskupini; bolnike s simptomi akutnega koronarnega sindroma in bolnike s simptomi, katerih simptomi niso v skladu z akutnim koronarnim sindromom. Zaradi nespecifičnih simptomov in znakov je prepoznavanje bolnikov s sindromom takotsubo še vedno diagnostični izziv. Hipoteze o hitrem okrevanju krčljivosti srčne mišice in ugodnem poteku bolezni so nedavno izzvali izsledki novejših raziskav, ki so pokazali primerljivo smrtnost in pogostost akutnih srčno-žilnih zapletov med bolniki s sindromom takotsubo in akutnim koronarnim sindromom. Prav tako novejši podatki kažejo, da podskupina bolnikov po akutni fazi sindroma takotsubo lahko razvije kronično srčno popuščanje. Sindrom takotsubo tako ni benigna bolezen in zahteva nove pristope k diagnostični in terapevtski obravnavi teh bolnikov. V članku želimo predstaviti novosti za razumevanje patogeneze in novosti pri obravnavi bolnikov s sindromom takotsubo in spremljati svoje izkušnje pri obravnavi teh bolnikov.

Published: May 2024

Aim: The aim was to confirm the correlation between chronological age, skeletal age according to X-ray picture of the hand and wrist, and the stages of teeth development, and to determine whether the assessment of teeth development can be used to establish the stage of growth of an individual. Material and method: 362 adolescents were included in the study; 180 boys between the age 11.5–15.5, 182 girls between the age 10.5–14.5. To assess teeth in OPG Demirjian’s classification was used. We assessed teeth 43, 44, 45 and 47 in the mandible, and 13, 14, 15, 17 and 18 in the maxilla. To assess radiographs of the hand and wrist Björk, Grave and Brown classification was applied. Results: The correlation of skeletal and dental age was proved. The highest correlation was found in lower permanent canine, both in girls and boys. S-stage in radiograph of the hand (the stage prior to the maximum growth spurt) corresponds to the stage of the lower canine root with parallel walls (G-stage according to Demirjian). Thus, in case OPG of lower permanent canine shows parallel walls of the root canal the maximum of growth spurt occurs within 0.5–1 year. The maximum growth spurt (MP3cap stage) and the following stages correspond to the situation when lower canine apex is closed (H-stage according to Demirjian). This can help us in the correct timing of orthodontic treatment. ORTODONCIE | ročník 33 | č. 2/2024 ODBORNÉ PRÁCE / ORGINAL ARTICLES Recenzovaný časopis České ortodontické společnosti 14 Conclusion: The assessment of the developmental stages of teeth, namely lower permanent canine, is used in the planning of orthodontic treatment, and can serve as
Derivative block methods for the solution for fourth-order boundary value problems of ordinary differential equations
Authors: Olabode Bola , Momoh Adelegan , Senewo Emmanuel
Published: May 2024

The application of block methods in the study of dynamical system is one area which needs more research. Therefore, this work presents block methods and its application to solve some problems in solid and fluid mechanics. The method was developed directly using the approaches of collocation and interpolation, and using power series polynomial as a trial solution. First, the system of linear equations is solved to obtain the unknown coefficients. The coefficients gotten are then substituted into the approximate solution to obtain continuous scheme. The continuous scheme, its first, second and third derivatives are evaluated at all the grid points to generate the block methods. The derived methods were applied to solve fourth-order boundary value problems of ordinary differential equations arising from beams and chemical problems. The results demonstrate the reliability and efficiency of the proposed method.

The study included accessions of wild annual Helianthus annuus L. (w.f.) and some perennial wild Helianthus species, preserved and maintained in the ex-situ collection at the DAI, General Toshevo. Two isolates of the pathogen were used for infection- Ph 21-6214 and Ph21-211, with each of which three plants from each sample were infected according to a 3x2 scheme. The plants‘ reaction was checked 21 days after inoculation on a nine-ball scale. High resistance (VR) to both pathogen isolates was found in 9 samples of Helianthus annuus L. (w.f.) and in 2 accessions of the perennials H. mollis and H. resinosus. Resistance (R) to both pathogen isolates was shown by two samples from the annual and one from the perennial species. Five samples of Helianthus annuus L. (w.f.) were found to be resistant to pathogen isolate Ph21-6214 and the same number to pathogen isolate Ph21-211. From the obtained results, it could be concluded that the observed reactions of high resistance and resistance in samples from wild species of sunflower can be successfully used as potential sources of genes for resistance to the pathogen in sunflower breeding.

In the new program period 2021-2027, the strategic goal for the development of European agriculture is defined as „stimulating and sharing knowledge, innovation, digitization and promoting their use to a greater extent“. The increasing number of animals on farms, the requirements for humane treatment and environmental protection, as well as the implementation of production systems with limited use of resources require new solutions that can be found in digital technologies used throughout the livestock system. Precision livestock farming involves the use of digital technologies. It aims to improve production and reproduction, animal welfare and facilitate targeted use of resources to reduce the impact on the environment and human health by precisely controlling processes.The implementation of PLF depends on: socio-demographic factors, size of the farm, production system, specialization of the farm, type of animals, animal husbandry technology, age of the farmer, country and region, etc.

The aim of the present study is to evaluate the values of some enzymes and metabolites - ALT, AST, ALP, serum iron and glucose of two herds of Bulgarian native sheep breeds raised at different altitudes, depending on the season, their body condition score (BCS) and the presence of gastrointestinal parasites. The research was conducted with 20 animals each in farms in the village of Mirkovo (715 m above sea level) with Sofia (Elinpelin) sheep breed and in the village of Gubesh (1040 m above sea level) with Central Balkan sheep breed. Body condition assessment was performed during sampling by one individual using an adapted system. Fresh faeces (total sample) were also collected for parasitological tests (coproovoscopy and coprolarvoscopy). Analysis of biochemical parameters was performed in extracted blood plasma with a BTS-350 semi-automatic biochemical analyzer. AST and glucose levels were normal, ALP and Fe were lower in both seasons, and ALT was higher than reference values limits only in summer for both breeds. There were significant differences between the two breeds in summer for BCS, ALT and glucose (p<0.001, p<0.05 and p<0.01 respectively), in winter - only for Fe (p<0.001) and in both seasons for HCT (p<0.001 and p<0.01 respectively), AST (p<0.001 and p<0.05 respectively) and ALP (p<0.001 each). Regarding the activity of AST, there are no significant differences between the two seasons and in both breeds, however, there are such differences only in Central Balkan sheep for BCS and Fe (respectively p<0.01 and p<0.001), and in both breeds together with different degrees of freedom - for all other indicators (HCT, ALT, ALP and glucose).

Published: May 2024

Bean anthracnose, caused by Colletotrichum lindemuthianum, is a key disease in a number of countries around the world. Depending on the varietal structure and climatic conditions, yield losses vary from 10-58% to the complete destruction of crops. For the conditions of Bulgaria, the disease has a sporadic character in the plain areas, but in the mountainous areas it occurs annually. The pathogen control is related to uninfected seed material, long crop rotation, destruction of plant residues, application of fungicides and use of resistant varieties. C. lindemuthianum is characterized by considerable virulence diversity, which makes it difficult to breeding resistant cultivars and leads to overcoming already achieved resistance. This publication summarizes research on the virulence diversity of C. lindemuthianum in Bulgaria over the last forty years. In parallel, data on the resistance of Bulgarian dry bean varieties, some of which are essential for production in the country, to a set of physiological races of C. lindemuthianum are summarized. The analysis of the identified races shows significant virulence diversity in the pathogenic populations in Bulgaria. During the period 1979-2006, 10 physiological races were identified - 2, 3, 6, 22, 23, 54, 73, 79, 81 and 131. Race 81 was dominantly prevalent (78.4% of isolates) in traditional dry bean growing areas in the country. Races 2, 6, 22, 54 and 131 are established in the Rhodopе Mountains and Pirin Mountains. Races 3, 23, 73 and 79 were incidental to Bulgaria and there is no confirmation of their distribution. Of the 17 varieties presented in the overview, resistance to 11 races of C. lindemuthianum has variety Pukliv 1. Variety GTB Blyan is susceptible to races 6 and 81 and resistant to the remaining 9 physiological races included in the test. The Pirina variety is resistant to 10 of the 11 races tested. The varieties Pukliv 1, Trakya and Pirina are resistant to race 81, which prevails in Bulgaria. All cultivars have resistance to one or more of the investigated physiological races, which makes it possible to include them as resistance donors in the breeding of dry beans, by the pyramidal accumulation of race-specific genes.

Published: May 2024

Split potassium fertilization is emerging as an effective technique for the prolonged assimilation of significant amounts of accessible potassium during the vegetation, with the aim of establishing a positive potassium balance in the soil and achieving increased yields of quality produce. The aim of this study was to determine the economic efficiency of the partitioning and split application of potassium doses in the cultivation of tomatoes, both in the early and mid-early production. The results showed that tomato plants demonstrate improved potassium utilization through split application, resulting in increased yields and total production revenues. Split fertilization alternatives proved to be economically viable, with N24Р12К8+8+8 approach being particularly beneficial in early tomato production. This study underlines the importance of optimizing fertilization practices in agriculture, highlighting the potential to increase economic efficiency and profitability for farmers and to ensure the sustainable use of soil resources.

Published: May 2024

The present study aims to establish the application of fluorescence spectroscopy as a field method in the determination of varietal differences after black radish harvesting. The experimental studies were conducted on site at the farm where the black radish accessions were grown. The fluorescence analysis was carried out with a source with an emission wavelength of 285 nm and an author-developed mobile fiber-optic experimental setup. The subjects of this research are root crops from Black Spanish round, Black Spanish long, Rattail, and Nero Tondo. The correlation between the emission signals of the samples was established. This fact allows mobile fluorescence spectroscopy to be successfully applied as a rapid tool to establish the origin of unknown black radish root crops in the presence of a rich library of spectra as an applied tool in breeding programs. The results of the experiment can be used to optimize the time for the analysis of the varietal differences of the black radish genotypes after harvest. Fluorescence spectroscopy in a fiber-optical configuration will support the process of determining the belonging of a specific variety to a given variety, even for samples of unknown origin, when it is necessary to qualify the result of accession in a short time.

Published: May 2024

Varieties from different оriental tobacco ecotypes are a great sensitivity to the conditions of the environment. In recent years, some varieties of tobacco have been grown in areas other than those for which they were selected. This necessitates to study their plasticity, morphology and quality in different untypical conditions. During the period 2021-2022, biometric, quality and some basic chemical indicators were investigated in the dry tobacco of the four varieties of Krumovgrad 90, Elenski 817, Dupnitsa 160 and Dzebel 576 belonging to four different ecotypes (Ecotype Krumovgrad, Ecotype Eastern Balkans, Ecotype Dupnitsa and Ecotype Dzebel Basma). The experiments were conducted in an еxperimental field (EF)-Markovo. The values of chemical indicators were determined in an Accredited Laboratory Complex (s) to TTPI. The results show that climatic conditions are a determining factor for plant development and for the quality of the raw material formed, with better biometric indicators reported in 2022. The investigated varieties have a relatively high percentage of the I-st class. In the conditions of EF - Markovo, the highest nicotine values were reported in the variety Elenski 817. Nicotine values in Dupnitsa 160 and Krumovgrad 90 varieties are lower in tobacco from the 2022 harvest. Climate conditions have a great impact on morphological and chemical indicators in the studied varieties.

Este estudo teve como objetivo realizar o mapeamento do uso e cobertura da terra, a identificação de conflitos e a degradação ambiental na Bacia Hidrográfica do Rio Guajiru, considerando a sua importância social e econômica como fonte de recursos naturais e atividades agropastoris e a proximidade da capital, Natal, no litoral leste do Rio Grande do Norte. Para o mapeamento e análise, utilizaram-se uma cena do satélite sensor MSI Sentinel 2 e a classificação supervisionada com emprego do Semi-Automatic Classification Plugin (SCP) do software QGis 3.16. Os resultados mostram que as pastagens recobrem 30% da área da bacia, seguida da caatinga arbóreo-arbustiva aberta, com 21,9%. Os campos antropizados, ocupados por atividades agrícolas, representam 19%, e as lâminas de corpos d’água ocupam 0,9% da superfície dos terrenos. Os resultados nas APPs mostram que 32,9% dessas áreas são ocupadas por pastagens, e 8,1%, por atividades antrópicas. Dados e informações de campo validam os resultados e atestam que os conflitos legais e a degradação ambiental na bacia estão amplamente distribuídos, com maiores impactos nas áreas de nascentes, e estritamente associados à ocupação humana desordenada.
