Mineralogical factors affecting the separation behavior of Ta-Nb-bearing minerals in the gravity field: mineral grain size, liberation, and association relationship
Authors: Cheng Hongwei , Xu Jian , Wang Shoujing , Lv Zihu , Wei Fushuai , Zhao Dengkui , Wu Dongyin
Published: October 2023

Gravity separation is the primary method used to beneficiate Ta-Nb-bearing minerals, however, it performs poorly in low-grade and fine-grained ores. A comparative study of gravity separation products (concentrate, middlings, and tailings) reveals the factors affecting the separation behavior of Ta-Nb-bearing minerals in the process combined with a spiral chute and shaking table from the perspective of mineralogy. The results reveal that columbite-tantalite is the principal Ta-Nb-bearing mineral. The grain size of columbite-tantalite in the concentrate is the coarsest, followed by that in the middlings, and the finest in the tailings, which are mainly distributed in the range of -150+38 μm, -75+20 μm, and-38 μm, respectively. The liberation degree of columbite-tantalite in the concentrate and tailings is positively correlated with grinding time, while that in the middlings is negatively correlated with grinding time. The density of columbite-tantalite-bearing particles in concentrate is mainly distributed above 3 or even 4, due to the high liberation degree of the columbite-tantalite in the concentrate, as well as the high amount of rich intergrowth associated with heavy minerals. The density of Ta-Nb-bearing mineral particles in the middlings and tailings is predominantly distributed in D<3. It demonstrates that the liberation degree is not the most essential factor in determining columbite-tantalite separation behavior in the gravity field, and the mineralogical characteristics of columbite-tantalite including grain size, association relationship, and particle density, may be more important. The results of this investigation can provide theoretical support for the strengthening separation of low-grade tantalum-niobium ore.

Evaluation of Non-revenue Water Management: A Case Study of Lodwar Water Supply in Lodwar Municipality, Kenya
Authors: Augustus Keya Mucholwa Wanjala , Nyanchaga Ezekiel Nyangeri , Njoroge Bernard N. Kimani
Published: October 2023

This paper scrutinises the availability and effectiveness of non-revenue water management practices at Lodwar Water Supply, which serves an urban populace in Arid, Northern Kenya. The case study is representative of medium-sized water utilities serving populations in water-scarce areas within developing countries. Challenges encountered by water utilities in developing countries are unique, and their resolution requires context-specific approaches. For instance, Lodwar water supply posted an estimated 52% non-revenue water in a recent assessment by Kenya’s water services regulatory agency (WaSREB). The utility lost half of its production. This is unacceptable for a water utility serving an arid service area with 43% water coverage. This paper documents the findings of a causal study conducted to identify probable reasons for the water utility performance and develop recommendations to reverse the worsening non-revenue water trend. Four aspects were identified for scrutiny at the water utility; these were: Availability of strategies, methods, and policies for non-revenue water reduction; Employee and Consumer awareness of non-revenue water management; Techniques for enumeration of components of non-revenue water and the nexus between the foregoing and the prevailing poor non-revenue water and overall performance of the water utility. Three hundred eighty-five questionnaires were administered to consumers, randomly sampled across the selected study area. This was followed by a non-quantitative audit of non-revenue water practices by the water utility and focused group discussions with top management and technical staff at the water utility. This study established the absence of deliberate strategies for control of non-revenue water by the water utility as the critical reason for the unacceptably poor non-revenue water and overall performance of Lodwar Water Supply. Recommendations for mitigation of non-revenue water included the establishment of zone-specific, updated consumer database; DMAs with functional inflow meters; acquisition of meter testing and calibration system; institution of active leakage control initiatives and personnel capacity development

Di Indonesia, prevalensi kejadian hipertensi semakin meningkat dari tahun ke tahun khususnya pada kelompok lansia. Pemahaman terkait hipertensi masih kurang khususnya pada kelompok lansia disertai juga dengan masih kecilnya persentase minum obat secara teratur. Hal ini mampu memberikan komplikasi berat hingga menimbulkan kematian. Berdasarkan hal tersebut, diperlukan intervensi preventif yaitu pemberian penyuluhan mengenai hipertensi pada lansia di Desa Melinggih Kecamatan Payangan Gianyar. Tujuan dari pemberian penyuluhan ini adalah agar para lansia mampu meningkatkan pengetahuannya mengenai penyakit hipertensi dan bagaimana pentalaksanaan yang tepat. Berdasarkan hasil pretest dari 279 responden lansia memiliki pengetahuan kurang tentang hipertensi yaitu sebesar 69.2%. Selanjutnya setelah diberikan penyuluhan, dari hasil posttest sebagian besar responden lansia memiliki pengetahuan yang baik yaitu sebesar 71%. Setelah diberikan intervensi penyuluhan dapat disimpulkan bahwa pengetahuan lansia mengenai hipertensi mengalami peningkatan.

Biomarkers in renal cell carcinoma and their targeted therapies: a review
Authors: Gupta Shruti , Shamsher Singh Kanwar
Published: October 2023

Renal cell carcinoma (RCC) is one of the most life-threatening urinary malignancies displaying poor response to radiotherapy and chemotherapy. Although in the recent past there have been tremendous advancements in using targeted therapies for RCC, despite that it remains the most lethal urogenital cancer with a 5-year survival rate of roughly 76%. Timely diagnosis is still the key to prevent the progression of RCC into metastatic stages as well as to treat it. But due to the lack of definitive and specific diagnostic biomarkers for RCC and its asymptomatic nature in its early stages, it becomes very difficult to diagnose it. Reliable and distinct molecular markers can not only refine the diagnosis but also classifies the tumors into thier sub-types which can escort subsequent management and possible treatment for patients. Potential biomarkers can permit a greater degree of stratification of patients affected by RCC and help tailor novel targeted therapies. The review summarizes the most promising epigenetic [DNA methylation, microRNA (miRNA; miR), and long noncoding RNA (lncRNA)] and protein biomarkers that have been known to be specifically involved in diagnosis, cancer progression, and metastasis of RCC, thereby highlighting their utilization as non-invasive molecular markers in RCC. Also, the rationale and development of novel molecular targeted drugs and immunotherapy drugs [such as tyrosine kinase inhibitors and immune checkpoint inhibitors (ICIs)] as potential RCC therapeutics along with the proposed implication of these biomarkers in predicting response to targeted therapies will be discussed.

Epidemiology, Genetics, Pathology and Clinical Features in Retinoblastoma
Authors: ALKAN Lütfi Raşid , ATALAY Hatice Tuba
Published: October 2023

Retinoblastoma is the most common intraocular tumor in childhood. 95% of retinoblastoma patients are younger than 5 years old. The RB1 gene mutation is mainly responsible for the genetics of the disease. However, in recent years, it has been shown that other genes are also effective and may cause different presentations. Although the International Retinoblastoma Classification is guiding in the treatment of retinoblastoma, it has recently been suggested that the TNM classification may be more useful for the disease. Many imaging methods are used in the diagnosis of retinoblastoma. Treatment of retinoblastoma is complex and needs to be tailored to the patient. Collaboration with an experienced ophthalmologist, pediatric oncologist, interventional radiologist, and radiation oncology is important. Despite this, there are many issues that cannot be clarified in retinoblastoma due to the genetics that are still not clearly revealed, different ideas in the classification, and the changes that may occur in its management.
Glial and Melanocytic Tumors of the Retina and Optic Disc
Authors: TANRIVERDİ Cafer
Published: October 2023

In this review, solitary limited retinal astrocytic proliferation, retinal astrocytic hamartoma, acquired retinal astrocytoma, optic disc melanocytoma and optic disc melenoma, which are glial and melanocytic tumors of the retina and optic disc, are discussed. The point that makes these diseases important is the necessity of making the differential diagnosis. Because while there are retinal tumors that can show complete regression in this group of diseases, there are also tumors where more severe clinical conditions can be seen that can lead to vision loss and even systemic metastatic spread. In addition, serious retinal and optic nerve complications can be observed in some tumors, which can lead to vision loss. Another important point is the malignant transformation that can be observed in tumors such as melanocytoma, although it is rare. For this reason, periodic follow-up of these cases in the presence of an experienced ophthalmologist is very important. This review aimed to summarize the clinical and histopathological features that may be important in the diagnosis and follow-up of these tumors.
Retinal Tumors Associated with Phacomatoses and Isolated Retinal Hamartoma
Authors: KÖKSALDI Seher , KAYABAŞI Mustafa , SAATCİ Ali Osman
Published: October 2023

The phacomatoses or neurocutaneous syndromes are a heterogeneous group of genetic disorders arising from the embryonic ectoderm, characterized by multiple congenital anomalies affecting the eye, skin, and central nervous system. Two of the most common phacomatoses are neurofibromatosis and tuberous sclerosis, and retinal manifestations may be seen in both these entities. Retinal astrocytic hamartomas are benign glial tumors that originate from astrocytes in the retinal nerve fiber layer. While they are classically associated with systemic phacomatoses such as tuberous sclerosis complex and neurofibromatosis, these lesions can also present as incidental findings in otherwise healthy individuals. It should be kept in mind that retinal involvement may accompany phacomatoses and detailed ophthalmological evaluation should be performed in these patients.
Primary Tumours of The Optic Disc and The Optic Disc Sheath
Authors: KESİM Cem , HASANREİSOĞLU Murat
Published: October 2023

Primary optic nerve and optic nerve sheath tumors constitute approximately 8% of intraorbital tumors and although most of them are benign, they are manifested by findings that significantly affect visual function such as vision loss, visual field defect and proptosis. Tumors originating from the optic nerve trunk are mostly benign optic nerve glioma, but rarer tumors such as ganglioglioma, medulloepithelioma, hemangioblastoma, melanocytoma and high-grade glioblastomas such as malignant optic nerve glioma can also be detected. Tumors originating from the optic nerve sheath usually have optic nerve sheath meningioma (ONSM), of those with intraorbital and intracanalicular origin are classified as primary and intracranial ONSMs are classified as secondary tumors. Optic glioma, ONSM, and hemangioblastomas can be seen sporadically or as a component of Type 1 and Type 2 Neurofibromatosis (NF) and Von Hippel-Lindau (VHL) syndromes, respectively. Treatment with systemic chemotherapy, surgical resection and radiotherapy methods should be considered when progressive vision loss, visual field defect and cosmetically intolerable proptosis develop in optic nerve and nerve sheath tumors, which can have a quiet course for years in terms of visual function. While systemic chemotherapy is accepted as the main treatment method in optic gliomas, more successful results are obtained with specialized treatment methods such as stereotactic fractionated radiotherapy in ONSMs.

La normativa ecuatoriana ha introducido valiosos cambios en su legislación mismos que en ocasiones se originan por medio de la jurisprudencia que emite la Corte Constitucional. En este orden de ideas el tema que se analiza dentro de la presente investigación responde a una necesidad básica y un derecho de los padres que se traduce por medio de la tenencia compartida. Si bien, los progenitores tienen la obligatoriedad de velar por el bienestar de sus vástagos, esta obligación en ocasiones debe ser exigida por medio de la vía judicial ante la falta de acuerdo entre los padres. Tradicionalmente, el rol de cuidado de los hijos y de la familia ha sido confiado a la mujer generando brechas de discriminación que no le han permitido desarrollarse de manera adecuada frenando sus expectativas laborales y limitándose frente a múltiples estereotipos. Bajo este criterio este articulo analiza la problemática expuesta vista desde un enfoque cualitativo, respondiendo a un análisis crítico propositivo. Los resultados obtenidos dan cuenta que, el régimen de preferencia materna en la patria potestad y la tenencia de los hijos es complejo y debe abordarse teniendo como referente los principios de igualdad de género y el interés superior de los menores.

Authors: Quijano Blanco Yobany , Gómez Gracia Julián David , León Perez Deicy Lorena , Perilla Molina Luis Ernesto
Published: October 2023

Se describe una técnica para la desarticulación de los huesos del cráneo con fines académicos, didácticos e investigativos. Esta técnica consiste en la introducción de semillas secas o deshidratadas en las diferentes cavidades craneales, seguida de su inmersión en un recipiente con agua. Esto provoca la hidratación de las semillas, aumentando su volumen y generando un incremento de la presión dentro de las cavidades craneales, lo que conduce a su posterior desarticulación. A través de este proceso, se obtienen todos los huesos que conforman el neurocráneo, el condrocráneo y el vicerocráneo. Al separar los huesos de esta manera, se logra preservar todos los detalles anatómicos, incluyendo su tridimensionalidad y sus elementos anatómicos característicos. Esto potencia las posibilidades de aprendizaje al conservar cada detalle de las piezas anatómicas, así como los procesos de investigación y extensión, dado que brinda la oportunidad de crear exhibiciones con las piezas obtenidas.

It is striking that, while the number of esports participants continues to rise, so is the volume of research on the subject. Furthermore, although the literature on esports players and chronotypes is relatively small, there are a few significant insights under the small findings. In this study, it was aimed to determine the chronotypes of young adults interested in esports and to examine the relationship between them and their physical activity status.

The participants in this study group included 190 participants aged 17 to 24 who are interested in esports and live in different regions of Turkey. A web-based survey was used to obtain data from esports players who participated in esports education. With this survey, the demographic information, playing time, physical activity status, and the Morningness–eveningness Questionnaire (MEQ) scale were applied to determine the chronotypes of the participants. Then, the distribution of the collected data was determined and analyzed with the SPSS 25 program.

The results of the study revealed that young adult participants interested in esports were primarily "neither type (62%)" and then "evening type (31%)". In addition, according to the IPAQ results, the physical activity levels of "evening type" were significantly lowest (p

Engellilik ve Spor Sosyolojisi
Authors: IŞIK AFACAN Meltem
Published: October 2023

İnsan, sosyal bir canlı olduğu için diğer insanlarla birlikte yaşar. Bu yaşam zorunluluğu, sosyal yaşam alanlarının insanlar tarafından kurulmasını gerektirir. Eğitim, sanat, spor gibi sosyal yaşam alanları yazılı ve yazısız olmayan kurallara göre belirlenir. Bu yaşam alanlarında yapılan her şey diğer insanlara da yansıdığı için toplumun kültürünü oluşturur. Eğitim kültürü, sanat kültürü ve spor kültürü gibi oluşan alt kültürlerin durumu, aynı zamanda o toplum için bir medeniyet göstergesidir. Medeniyetin temel göstergelerinden biri, spor gibi insan birlikteliklerinde oluşan etkinlikler ile ilgili sosyal faydanın paylaşılma seviyesidir. Çünkü her insan, hayat koşullarını ilgilendiren yetenek ve becerilere aynı derecede sahip değildir. Dolayısıyla sosyal yaşamın fırsat ve olanaklarından herkesin faydalanabilmesi için resmi ve özel tüm kurum ile kuruluşların yapması gereken görevleri ve almaları gereken sorumlulukları vardır. Sporda engellilik konusuna bu bakış açısından yaklaşmak spor sosyolojisinin amaçlarından biridir. Çünkü spor sosyolojisinin merkezi alanı spor ve spor insanıdır. Engelli sporcular için spor ortamlarına girmek çoğu zaman önemli bir sorun olarak görülmektedir. Bu nedenle engelli spor insanları, engelsiz spor insanlarına göre gelişimsel açıdan geride kalmaktadır. Dolayısıyla bu çalışmada öncelikle spor kültürü içinde farklılıklara ve farklı olanlara bakıştaki değişmelere spor sosyolojisi açısından değinilecektir. Daha sonra spor sosyolojisinde engelliliğin ne olduğu konusu ele alınacaktır. Bu bağlamda çalışmanın temel amacı, engelli sporunun ve engelli spor insanlarının spor sosyoloji açısından araştırılmasının önemi ve gerekliliğini ortaya koymaktır. Araştırma yöntemlerinden betimleme yönteminin kullanıldığı bu çalışmanın engelli sporları konusundaki farkındalığa katkı sağlayacağı ve benzer çalışmalara öncülük edeceği tahmin edilmektedir.

Bu çalışmanın amacı oryantiring sporu yapan bireylerin hedef bağlılığı, karar verme stilleri arasındaki ilişkinin incelenmesidir. Hedef bağlılığı ve karar verme stilleri puanlarının bağımsız değişkenlere göre incelenmesidir. Araştırmanın örneklemini; İzmir ilinde lisans ve lisansüstü düzeyde oryantiring sporu yapan bireylerin arasından kolayda örnekleme yöntemiyle seçilen 401 birey oluşturmaktadır. Araştırma verilerinin toplanmasında kişisel bilgi formu, hedef bağlılığı ve karar verme stilleri ölçekleri kullanılmıştır. İki ölçek arasında istatistiksel olarak anlamlı bir ilişki bulunmamaktadır. Cinsiyete, yaşa ve ekonomiye göre puan ortalamaları istatistiksel anlamda farklılaşmamaktadır. Eğitim düzeyine göre ise ölçek alt boyutlarında ve toplam puan ortalamalarında istatistiksel olarak anlamlı düzeyde farklılaştığı ve bu üç puan ortalamasında da lisans düzeyindekilerin ortalamalarının lisansüstündekilere göre yüksek olduğu görülmektedir.
The Fragility of Governmentality and Domination: The State, Carceral Labour and “(In)docile Resistance” in the Late Ottoman Empire
Authors: Yildirim Kadir , Akkuş Yakup
Published: October 2023

The “power relations” in the Ottoman Empire were gradually governmentalised and centralised through modernist reforms in the long nineteenth century. As part of this process, the practice of intramural and extramural carceral labour became an important element in the Ottoman penal system in the late empire. Despite the state’s emphasis on the rehabilitative effect of prison labour in legal regulations, particularly regarding intramural carceral labour, the expansion of the practice into extramural activities reveals that providing economic benefits was another driving force in the Ottoman case. In this line, extramural labour was used as a complement to free labour rather than a substitute for it. However, the adverse reactions of prisoners to carceral labour were just as important as the regulations, disciplinary practices, and the administrative and financial limits of the state in determining the success of the practice. By focusing on the resistance strategies of prisoners, including escapes, writing petitions, collective walkouts, slowdowns, strikes, and pilferage, this paper aims to amplify their voices. This prisoner-centred view enables us to take a Foucauldian perspective in the context of power relations and resistance to such practices and to illustrate how prisoners, as “indocile bodies,” weakened the governmentality and domination of the state through many forms of “indocile resistance.”
Temporal patterns of roe deer (Capreolus capreolus) traffic accidents in Lithuania: effects of daytime, season and lunar phase
Authors: GALINSKAITĖ Lina , IGNATAVIČIUS Gytautas
Published: October 2023

In many countries road safety and animal protection pose a serious problem due to wildlife-related accidents.
Profound information of temporal and spatial patterns of deer-vehicle accidents is necessary for safe mitigation
efforts and further accident analysis. We described the temporal patterns of roe deer (Capreolus capreolus) vehicle collisions
from 2014 till 2021 in Lithuania. Using a comprehensive dataset, consisting of 19.707 data points, we examined
the influence of different time units (i.e. day of year, day of week, month) and moon illumination percentage. Therefore,
we identified roe deer peak accident periods within the time units. Highest frequencies of collisions occurred in May,
November and December. Between days of the week collisions increased on Friday with a secondary peak on Saturday.
Relationships between roe deer vehicle collisions (RDVc) and lunar phases were analyzed, providing evidence for high
frequencies of RDVc during full moon illumination. We believe that RDVc are dependent both on human activity in
traffic and wildlife activity. Overall our results highlight, that RDVc disturbance among time is nonrandom. Methods
to effective reduce deer-vehicle accidents should be adapted to species-specific temporal periods or place and concentrated
to short-term mitigation measures (e.g. speed limits, wildlife warning signs, traffic controls).
Middle-term field research on air and noise pollution in the city district of Baltic region

Air quality monitoring, as well as physical pollution, in particular noise, is an important component for assessing
the quality of life in cities and their regions. Detailed and accurate studies require an analysis of the results obtained
with at least an average time interval, which was carried out in this study of the environmental situation in the
area of the city of the Baltic region. The results obtained can identify the main areas of greater pollution, enabling new
planning of communication systems in small towns, as well as avoiding negative effects on the body of residents, thereby
improving overall health. The data was obtained using a mobile laboratory and high-precision equipment, based on
international standards for parameter measurement techniques. According to the results of the research, trends were
found to reduce particulate matter up to 10 microns, depending on the seasons, by more than 10%. The noise level in
most of the area remains unchanged, or gradually increases due to large traffic flows. In contrast to the recreational
area, the greatest increase in pollution in the residential area found PM10, NO2 and benzene, by 30%, 39% and 72%
respectively. In the area adjacent to the road infrastructure, concentrations of benzene, ethylbenzene and toluene were
37–54% higher than in the recreational area. The average concentrations of other pollutants were lower.

The work deals with the issues of nitrogen and phosphorus removal from wastewater. Natural and modified
sorbents: zeolite, glauconite, and bentonite were tested under laboratory conditions. The studies used effluent from
biological wastewater treatment that contained an average concentration of 2.2 mg/L of ammonium nitrogen; 7.6 mg/L
of nitrate nitrogen and 8.7 mg/L of phosphate phosphorus concentration. Wastewater (0.5 L) was mixed with sorbents
(5 g) at a speed of 200 revolutions per minute, then nitrogen and phosphorus concentrations in the solution were
measured. Natural glauconite and bentonite removed 58–60% ammonium nitrogen, while modified sorbents show
higher 63–70% ammonium nitrogen removal efficiency, respectively. Clinoptilolite removed ammonium nitrogen from
wastewater with 76% efficiency. The tested sorbents removed nitrate nitrogen with 14–15% efficiency and phosphate
phosphorus with 19–45% efficiency.

Published: October 2023

The article provides statistical data on the damage to critical and road infrastructure as a result of the armed
aggression of the Russian Federation against Ukraine. Also, taking into account the constant missile attacks and destruction
make it impossible to restore and operate sections and systems of communication routes, which leads to
greater wear and tear and the inability to use them as intended. The purpose of this research is the analysis of the system
of communication routes and the development of the stages of restoration of their operation with the calculation
of the estimated need for financing. The article presents the possibility of harmonizing regulatory, legal and organizational
aspects of the transport industry of Ukraine with EU countries to meet the needs of the population in transportation
and ensure the development of the country’s economy by changing approaches to the formation of transport
and logistics solutions and the development of modern transport infrastructure. What the stages of recovery involve:
short-term (at the stage of martial law); medium term (restoration and restart of systems); modernization (deepening
the integration of the national transport network with the EU transport network).
Purification of the water environment from ammonium nitrogen during nitrification in natural reservoirs and in water use facilities
Authors: IURCHENKO Valentyna , UGNENKO Ievgeniia , MELNIKOVA Oksana , SOROKINA Kateryna
Published: October 2023

Nitrification are two unique reactions of sequential oxidation of ammonium nitrogen, carried out by chemolithoautotrophic
bacteria and archaea. Establishing the main source of nitrification in aquatic ecosystems is necessary
to manage this process. In experimental researches it has been established that in natural water bodies with a low
technogenic load, nitrification is caused by processes in bottom sediments, in areas of water bodies after wastewater
discharge – by processes in the water column. In technogenic environments (water use facilities) nitrification is caused
by processes in solid phases (filter fillings and activated sludge). Nitrification activity of activated sludge in treatment
facilities with deep biological treatment is high and the discharge of deeply purified wastewater into natural water bodies
leads to an increase in the processes of nitrification and the activity of self-purification from nitrogen compounds
in them.

More than 40% of natural riverbeds of Lithuanian rivers have been affected by straightening, in the installation
of melioration systems. The solution of gentle renaturalization was chosen and mild renaturalization measures
were installed in straightened sections of riverbeds. A detailed assessment of the ecological condition of the renaturalized
river sections was carried out according to the physico-chemical, ecological condition, biological (fish index, river
macroinverte-brates, river macrophyte indexes) quality elements at 2019–2022. The results of complex studies show the
renaturalization measures implemented have the greatest positive effect on the studied parameters in the river with the
strongest turbulent flow formed.
