Introduction: Surgical management of foramen magnum (FM) tumors is challenging by virtue of their location and vital neurovascular relationships. The ideal approach to anterior/anterolateral tumors continue to evoke controversy even in the modern era. In this article, we present and discuss our experience in the surgical management of these tumors. Materials and Methods: This retrospective study includes 29 consecutive patients (mean age 36.6 years, M: F = 2.63:1) of extramedullary tumors at the surgical foramen magnum, operated at our center, between 2007 and 2012. Results: Their mean duration of symptoms was 14. 6 months. A majority of the patients presented with motor symptoms (quadri/paraparesis, n = 21, 72.4%), neck pain with/without suboccipital radiation (n = 16, 55.2%) and sensory symptoms like tingling/numbness (n = 16, 55.2%). There were nine extradural (31%) and 20 intradural tumors (69%). Most of the tumors were located posterolateral to the neuraxis (n = 13, 44.8%). Nerve sheath tumors (n = 11, 38%) and meningiomas (n = 5, 17.2%) were the most commonly encountered histologies in our series. The standard posterior approach was the most frequently employed surgical approach (n = 20, 69%). Operative mortality and morbidity were 3.4 and 18.9%, respectively. At a mean follow-up of 27.3 months, 13 out of the 18 available patients improved. Conclusion: A majority of the foramen magnum tumors are amenable to excision via the standard posterior approach. Small anterior dural-based meningiomas/recurrent tumors may require a lateral approach like the far lateral approach.
Importance of C1 laminectomy in foramen magnum decompression surgery: A technical note
Authors: Kumar Ashish , Bhattacharjee Suchanda , Sahu Barada
Published: September 2022

Arnold-Chiari malformations (ACM) of the brain result from aberrations in the development of the posterior fossa resulting in its smaller volume leading to tonsillar herniation. The most common type includes Type I ACM where tonsillar descent reaches up to either C1 or C2 along with cervico-dorsal syringomyelia. The surgery (foramen magnum decompression, [FMD]) is usually straight forward and includes sub-occipital craniectomy and cervical laminectomy based on the level of descent. Rarely inadequate cervical laminectomy of C1 arch may result in residual compression at the level of obex even after "lax" duraplasty. A cervico-dural angle (angle between the neo-dura and cervical dura) at level foramen magnum can be observed in these patients. This angle is usually obtuse in imaging of cranio-vertebral junction (CVJ) of normal people and in postoperative patients of Chiari malformations where normal anatomy is restored. Inadequate C1 laminectomy may result in an acute cervico-dural angle with residual compression at the level of CVJ. Therefore, C1 laminectomy becomes a key step in FMD surgery that is often underemphasized, and neurosurgeons should be careful in doing it adequately.

Published: September 2022

The coexistence of a pituitary macroadenoma and a tuberculum sellae meningioma is very rare. This article demonstrates the surgical technique of the simultaneous resection of a pituitary macroadenoma and a tuberculum sellae meningioma using an endoscopic, endonasal, biportal, transsphenoidal approach. A 36-year-old woman presented with frontal headache and extended visual field loss of the right eye. She underwent cranial magnetic resonance imaging (MRI) revealing a 2 × 2× 2.5 mm contrast-enhancing intrasellar and suprasellar lesion with compression of the optic chiasma. The coexistence of a pituitary macroadenoma and meningioma was suggested. A biportal endoscopic endonasal transsphenoidal approach was performed to remove both lesions. The histological results confirmed the coexistence of the pituitary macroadenoma and meningioma, World Health Organization (WHO) grade I. The endoscopic, endonasal, transsphenoidal approach is a safe and reliable minimal invasive surgical alternative for resection of the intra-, supra- and parasellar lesions, avoiding additional craniotomy.

Published: September 2022

True Recurrent artery of Heubner (RAH) aneurysms are extremely rare and only three cases have been reported in the literature. We report a case of RAH aneurysm in a patient with World Federation of Neurosurgical Societies grade one subarachnoid hemorrhage (SAH), detected only on delayed cerebral angiography. We propose that an aneurysm in this location should be considered in the differential diagnosis of angiogram-negative SAH, and all vascular imaging studies be carefully scrutinized for RAH aneurysm

Published: September 2022

Background:

Evaluating the performance of the available machine learning software is fundamental to ensure trustworthiness and improve automated diagnosis. This study compared the diagnostic accuracy of artificial intelligence (AI) system reporting with human readers for portable chest anteroposterior (AP) x-rays acquired patients in a semi-recumbent position.

Methods:

Ninety-four patients who underwent portable chest AP with clinical suspicion or confirmed COVID-19 were included in the study; among them, 65 were COVID-19 positive and 29 had symptoms. High-resolution computed tomography (HRCT) Chest was available for 39 patients. Images were read by two radiologists (R1, R2) and AI. In case of disagreement between R1 and R2, a third radiologist (R3) read the images; however, if HRCT Chest was available, we counted HRCT Chest instead of R3. Thus, the gold standard was HRCT or R1 = R2, R1 = R3, or R2 = R3.

Results:

The sensitivity of the AI system in detecting pleural effusion and consolidation was 100% and 91.3%, respectively. The specificity of the AI system in detecting pleural effusion and lung consolidation was 84% and 61%, respectively. Nevertheless, there is no good agreement between the gold standard and AI in the case of other chest pathologies.

Conclusion:

Significant moderate agreement with AI and gold standard was shown for pleural effusion and consolidation. There was no significant agreement between the gold standard and AI in the case of the widened mediastinum, collapse, and other pathologies. However, future studies with large sample sizes, multicentric with multiple clinical indications, and radiographic views are recommended.

Published: September 2022

Bisphenol A is a common environmental factor and endocrine disruptor that exerts a negative impact on male reproductive ability. By exploring bisphenol A-induced testicular cell death using the Institute of Cancer Research (ICR) mouse model, we found that a ferroptosis phenomenon may exist. Mice were divided into six groups and administered different doses of bisphenol A via intragastric gavage once daily for 45 consecutive days. Serum was then collected to determine the levels of superoxide dismutase and malondialdehyde. Epididymal sperm was also collected for semen analysis, and testicular tissue was collected for ferritin content determination, electron microscope observation of mitochondrial morphology, immunohistochemistry, real-time quantitative polymerase chain reaction, and western blot analysis. Exposure to bisphenol A was found to decrease sperm quality and cause oxidative damage, iron accumulation, and mitochondrial damage in the testes of mice. In addition, bisphenol A was confirmed to affect the expression of the ferroptosis-related genes, glutathione peroxidase 4 (GPX4), ferritin heavy chain 1 (FTH1), cyclooxygenase 2 (COX2), and acyl-CoA synthetase 4 (ACSL4) in mouse testicular tissues. Accordingly, we speculate that bisphenol A induces oxidative stress, which leads to the ferroptosis of testicular cells. Overall, the inhibition of ferroptosis may be a potential strategy to reduce male reproductive toxicity caused by bisphenol A.

Authors: Odusolu Patience O , Egbe John J , Okpebri Komommo O , Uduigwomen Praise A
Published: September 2022

Background:

Intrauterine contraceptive device (IUCD) is an effective long-acting reversible contraceptive method that is suitable for women of reproductive age. Despite this, its uptake by women in Nigeria is not optimum.

Objectives:

The objectives were to determine the uptake, demographic characteristics of users, and reasons for the removal of IUCD use at the University of Calabar Teaching Hospital (UCTH), Nigeria.

Materials and Methods:

This was a retrospective study of family planning clients, who accepted and inserted IUCD at UCTH, Calabar, between January 1, 2013, and December 31, 2017. Case records of clients were retrieved and reviewed. Data extracted were entered into excel and analyzed using SPSS.

Results:

Out of 10,102 clients during the period, 1,032 clients accepted and inserted IUCD, giving an uptake rate of 10.2%. There was a gradual decline in the uptake of IUCD from 383 (37.1%) in 2013 to 96 (9.3%) in 2017. The sociodemographic features of IUCD users showed a mean age of 33.53 ± 5.94 with the majority, 696 (67.4%) having tertiary education. The majority were para 3 or 4 and accounted for 627 (60.7%), whereas 662 (64.2%) had previously used a modern contraceptive method. Sixty-five (6.3%) clients had their IUCD removed. The commonest reason for the removal was desire to get pregnant, 44 (67.7%), and side effects of IUCD (20.6%).

Conclusion:

There was a low uptake of IUCD, with a decline in the trend over the study period. Side effects affected the removal of the the IUCD. There is a need for awareness creation and education of women, appropriate counseling, and good patient selection in order to increase uptake.
Malaria in pregnancy
Authors: Ikpeama Edith C , Udealor Peter C , Onwuka Chidinma I
Published: September 2022

Background:

Administration of intermittent preventive treatment (IPT) in pregnancy is recommended for all pregnant women living in areas of stable malaria transmission. In order to increase the chances of a parturient receiving adequate number of IPT in pregnancy, World Health Organization (WHO) now recommends that it should be commenced from second trimester and given every month (at least 4 weeks apart) until the time of delivery, however, this recommendation is not being practiced by all doctors attending to pregnant women.

Objective:

To determine the conformity of Doctors to monthly prescription of IPT till delivery.

Materials and Methods:

This was a cross-sectional survey of antenatal clinic Doctors’ prescription of IPT during pregnancy in Enugu state. Information obtained included the socio-demographic characteristics of the Doctors, knowledge of IPT in pregnancy for malaria and implementation of the new IPT policy. A P-value of <0.05 was considered statistically significant.

Results:

A total of 119 doctors participated in the study. The mean age of the doctors was 36.15 +/- 2.42 years. One hundred and seven (89.9%) of the respondents had good knowledge that IPT is for prevention of malaria. One hundred and eighteen (99.2%) used sulphadoxine-pyrimethamine for IPT. One hundred and fourteen (95.8%) respondents knew that IPT should be commenced in second trimester, and 85.7% conformed to the new monthly policy of IPT prescription. Among the 20.2% of doctors who prescribed IPT only for 2 – 3 times during pregnancy, 13 (54.2%) gave the reason that they were comfortable with the old pattern of stopping at 36 weeks. There was significant association between knowledge of IPT in pregnancy and year of attainment of MBBS (P = 0.015). Age (P = 0.006) and level of practice (P = 0.002) were significantly associated with practice of the new IPT in pregnancy policy.

Conclusion:

There was high conformity to monthly IPT prescription until delivery among doctors in Enugu, Nigeria.

Published: September 2022

Recently acquired olfactory dysfunction (OD) has emerged as one of the hallmark manifestations of the novel coronavirus disease (COVID-19), but the evolution of its spontaneous recovery has remained inconclusive, with reports of persistence of OD beyond 6 months of onset. We undertook this systematic review and meta-analysis with a view of generating a pooled recovery rate of COVID-19-associated ODs and attempt to examine the predictors of olfactory recovery. A systematic search of Scopus, Google Scholar, and PubMed databases, comprising all longitudinal studies reporting the trajectory of COVID-19-related OD, was carried out. The pooled recovery rate was estimated with random-effects model, and the potential heterogeneity of the subgroup sources was analyzed using a meta-regression test. After the Preferred Reporting Items for Systematic Reviews and Meta-Analysis selection process, 28 studies from 16 countries were included, with a total of 5,175 OD patients, among 11,948 COVID-19 cases. The estimated global pooled recovery rate of OD was 82.7% (95% confidence interval, 77.46–88.04%), with a pooled median duration of OD of 11.6 days. Only 2 out of 28 studies had recovery data beyond a period of 2 months. But no significant difference was found in the recovery rate regarding the length of follow-up (P = 0.840). Studies that conducted objective olfactory assessments showed a significantly higher recovery rate than those with subjective assessments (P = 0.001). Although 10 studies (36%) reported >90% recovery, 9 studies (32%) documented persistence of OD in >25% of their patients. Five out of six studies showed that hyposnia tended to show complete recovery than anosmia. Age, co-morbidities, and intranasal treatments had no effects. Test of homogeneity between subgroups using Cochran's Q test was not significant (Q = 0.69, P = 0.40). Our meta-analysis revealed high rates of early- and medium-term recovery of COVID-19-related OD. However, it also showed disturbing rates of persistence of OD. Anosmia tended to be predictive of residual OD than hyposmia. Age, comorbidities, intranasal corticosteroid, and decongestants had no effects on OD recovery.

Published: September 2022

Introduction:

Pulse oximetry is currently used to screen for obstructive sleep apnoea (OSA) in children. However, its use in infant has not yet been well studied.

Aim:

The aim of this study was to develop a screening criterion using pulse oximetry to identify infant with probable OSA.

Materials and Methods:

This was a retrospective cross-sectional study including infants <1 year of age with features of upper airway obstruction or requiring home oxygen to find associations between obstructive apnoea hypopnoea index (OAHI) in infant polysomnography (PSG) and parameters in pulse oximetry by Spearman Rho’s correlation. The factor with the strongest correlation is further analysed by receiver-operating characteristic (ROC) curve to identify a cutoff with highest Youden index to screen for probable OSA (OAHI >2 per hour).

Results:

A total of 27 infants were studied. The index of oxygen desaturation with SpO2 <90% per sampled hour (ODI<90%) had the best correlation with OAHI (r = 0.52, P = 0.005). Using the cutoff of ODI<90% more than 1.3 per hour, the sensitivity and specificity for identifying OAHI >2 per hour was 77% and 71%, respectively.

Conclusion:

Infant pulse oximetry can be a useful tool to screen for probable infant OSA especially for paediatric units not offering infant PSG service.

Published: September 2022

Diplostomid trematodes (Digenea) include a wide and diverse group of common digeneans. Diplostomid larval stages are significant pathogens that may exert grave effects on both natural fish and aquaculture populations. Diplostomum species, which use fish as a second intermediate host, is one of the most common trematode species, which affects the fish welfare negatively with the formation of cataracts by settling in the eye. This study is determined the molecular characterization of Diplostomum parasite in Cyprinus carpio and Capoeta umbla for the first time from Turkey, based on the mitochondrial COX1 sequence data. Diplostomum samples were determined as Diplostomum spathaceum according to the phylogenetic trees created in the light of the morphological and COX1 sequence data. Sequence results matched ~98-100% with D. spathaceum as a result of blast analysis. It was defined that this parasite was represented by three different haplotypes in Turkey. As a result of haplotype analysis performed on a total of 162 isolates in GenBank and obtained in this study, 40 polymorphic regions and 58 haplotypes were determined. This haplotype network had arranged within a star-like configuration with a main central haplotype. This shows that the variation within D. spathaceum species is quite high. The mean abundance, mean intensity, and prevalence of the parasite in C. carpio were 8.29 (5.80-11.24), 10.91±9.37 (1-39), and 76%, respectively. In the C umbla, mean abundance, mean intensity, and prevalence were calculated as 11.54 (10.16-12.92), 14.07±16.59 (1-67), and 82%, respectively.

Published: September 2022

This study displays the application of the quantile regression theory to predict the size heterogeneity of cultured organisms. The analysis was applied to empirical data of the tilapia cultured in freshwater. Tilapia was cultured at four diets (50%, 80%, 100%, and Satiation). The quantile regression (QR) demonstrated to successfully model the size heterogeneity in tilapia (p<0,05; u<0,20), due to the feeding strategies effect. These results indicate tilapia fed an 80% ration size simulated a maximum biomass of 2,345.17 and 2,853.38kg at the harvest size of 200-300g (at 180 days) and 300-400g (at 210 days). The simulation of the quantile curves at a higher production scale allowed an estimate of the biomass distribution according to different market sizes, this strengthens management decision making in tilapia aquaculture. Implications of quantile regression and size heterogeneity in aquaculture are presented here.

Authors: Paras Andrea , Mitchell Lynne
Published: September 2022

The old adage that travel broadens the mind may not hold true for every student studying abroad. While pre-departure and in-country support for intercultural learning can help, some students still fail to develop their intercultural competence and some even go backwards. Using a combination of quantitative (Intercultural Development Inventory) and qualitative measures, this study examines what happens in intercultural learning when students participated in a four-week experiential field school in India, preceded by a twelve-week preparation course on the ethics of international voluntourism. Results found that, while students’ pre- and post-trip Intercultural Development Inventory results varied, qualitative data gave insights into student learning and revealed important lessons for educators.

O IDENTITETU SRPSKOG JEZIKA

Published: September 2022

Die Kombination aller Umstände und gesellschaftspolitischen Umstände, die die Entwicklung der literarischen serbischen Sprache begleiten, im historischen Kontext von zwei Weltkriegen und einem Bürgerkrieg, in dem Serben ständig für Freiheit und Unabhängigkeit kämpften, bedingten die Identität der serbischen Sprache sich, wohl oder übel, an die gesellschaftspolitische Situation anzupassen, in Übereinstimmung mit der vorherrschenden Ideologie, der die Serbistik als Linguistik bzw. ihre prominentesten Vertreter, folgt. Diese Veränderungen gefährdeten seine äußere Identität nicht – nach anderen verschiedenen Sprachen, Slawisch und Nichtslawisch, wurde er klar und ausreichend getrennt. Seine unterschiedlich polarisierte innere Identität hat sich verändert, hauptsächlich auf soziolinguistischer Ebene, auf der Ebene von Normen – der Rechtschreibung und des Wortschatzes, was die Struktur des Sprachsystems weder bedroht noch modifiziert, was tatsächlich zeigt, dass das System der serbischen Sprache ein Supersystem seiner Varianten ist, die mit dem Zerfall Jugoslawiens nationale Namen und den Status von Amtssprachen erhielten. Diese Veränderungen führen zu einem Rückgang der Zahl der Sprecher, die ihre Sprache Serbisch nennen, d. h. die Vitalität der serbischen Sprache ist gefährdet, die durch den nachlässigen Umgang ihrer Sprecher mit den Ressourcen und Regeln ihrer eigenen Sprache negativ beeinflusst wird, insbesondere mit der kyrillischen Schrift als identitätsstiftende Nationalschrift, die im Gebrauch marginalisiert wird. Aus diesem Grund muss die Sprachenpolitik die Verfahren zum Schutz der serbischen Sprache und zur Revitalisierung und Pflege der kyrillischen Schrift als philologische und ethnologische Vertikale der serbischen Sprache und des serbischen Volkes planen und konkretisieren.

To increase the corrosion resistance of stainless steel from local types of corrosion, chromium oxide coatings obtained from electrolytes modified with SiO2·nH2O were applied to its surface. It has been established that the coatings obtained from the electrolyte with the addition of SiO2·nH2O are continuous, without cracks, and finely crystalline compared to the coating obtained from the base electrolyte. Elemental analysis did not show the presence of silicon in the composition of the coating obtained from the modified SiO2·nH2O electrolyte, however, it showed the presence of a larger amount of chromium compared to the coating obtained from the base electrolyte. On the polarization curves, there is a complication of the release of hydrogen at the cathode and oxygen at the anode, which indicates a decrease in the electrical conductivity of the obtained coatings. The results obtained make it possible to recommend the use of SiO2·nH2O additives to the electrolyte to obtain chromium oxide coatings on steel with enhanced corrosion protection properties.

Authors:   Musamus University Merauke, Indonesia, Sahupala Peter
Published: September 2022

Sago is a native plant of Indonesia, with an area of ​​about 1.128 million ha or 51.3% of the world's sago area. Potential areas for producing sago (Metroxylon sp.) in Indonesia include Riau, South Sulawesi, Southeast Sulawesi, North Sulawesi, Maluku and Papua, where about 90% of the sago area in Indonesia is in Papua. From studies conducted by non-governmental organizations (NGOs) such as WWF which in May 2014 conducted various studies on the utilization of agricultural wastes that can still be used as alternative energy sources, which of course must be studied further. The study must of course be tested in the laboratory. Studies in the laboratory involve ultimate testing based on chemical content tests and proximation studies (thermal properties of fuel). This study must be carried out with the aim of knowing whether the sample to be used as fuel is feasible or not. This research is to do laboratory testing to determine the chemical composition of briquettes, thermal properties. The 60, 80 mesh size briquettes are molded in a cylindrical shape. The results of printing sago dregs charcoal briquettes consist of 60 mesh and 80 mesh, where the two briquettes have the following dimensions for a grain size of 60 mesh, briquette diameter b = 44.90 mm = 4,490 cm, briquette mass = 0.17 gr, briquette height = 69.80 mm = 6.980 cm.

Marl is limestone mixed with clay that is formed through the process of sedimentation. In this study, the authors used marl in the form of powder originating from the outskirts of the Komering Martapura river because marl has a very high silica content of 74.5%. The purpose and objective of this research is to find out how much influence the addition of marl powder has on the compressive strength of K300 concrete and what is the best percentage of adding marl powder to the compressive strength of concrete. This study used 30 cube-shaped test objects from 5 conditions with 6 kinds of variations. From the test results, the compressive strength of normal concrete characteristics is 303.591 kg/cm2, for the addition of 5% marl powder is 311.376 kg/cm2, for the addition of 10% marl powder is 320,713 kg/cm2, for the addition of 15% marl powder is 329.065 kg/ cm2, for the addition of 20% marl powder at 333.540 kg/cm2, and for the addition of 25% marl powder it is 327.491 kg/cm2. Based on the compressive strength test that has been carried out, it can be concluded that the increase in the maximum characteristic compressive strength in mixed conditions is 20%.

China managed to built-up a working market economy transforming itself into dominant player on global scale and put more emphasize on innovation-driven growth. In the course of this unprecedented process, Chinese Small and Medium sized Enterprises (SMEs) have established in huge numbers and become the most dynamic actors in the market economy. They have significant role in the domestic economy in profit creation, employment absorption, taking into practice different types of innovations largely contributing to the social stability and raising of well-being of the local communities. Furthermore, internationalization has also become important factor for the continuously developing SMEs in China. Beyond the observed negative tendencies- significant shrinkages of the SME’s profits - can be many different reasons. The central government has tendency to prioritizing the large size state enterprises in certaing industrial and service sectors, the insufficient size and frequency of the strategic innovations largely due to the lack of know-how, information, skills, competencies, attitude, network-based co-operations and experience of domestic and international markets. These also pointed out the relevance on the strategic innovation and how to impact on the product and process innovation on the SME’s technologies, business models, reshaping the corporate cultures and values as well to stop and reverse his negative trends. It means a defined product strategy, adequate financial and human resources, New Product Development (NPD) R&D resources, high quality project teams, senior management commitment, innovative environment and culture. Crossfunctional teams and top management should responsible for the implementation. This review paper is aiming to give a comprehensive landscape about the current situation of and the special features of the Chinese SME sector and the obstacles that can hindering or slow down their successful innovation processes. These challenges are particularly difficult for SMEs with smaller scale and weaker risk tolerance. Chinese domestic firms have comparative advantages, such as cheap labour resources, better knowledge about Chinese local market comparing to foreign MNEs from developed countries. Facing strong competition both from large-sized State Owned Enterprises (SOEs) and foreign Multinacional Enterprises (MNEs), Chinese SMEs should pay more attentions to indigenous innovation by taking advantage of Chinese huge domestic market.

A 2-year-old, male, weighing 2.4 kg, crossbred cat was brought to Siirt University, Faculty of Veterinary Medicine, Clinic of Surgery Department, due to traffic accident. A diffuse, palpable, painless swelling was detected under the skin on the area starting from the right cranio-lateral abdomen to the right cranio-lateral thorax. In the orthopedic examination, there was pain in the pelvic region and asymmetry at the right coxa-femoral joint. In the radiological examination of the thorax and abdomen, there was damage to the right lateral thoracoabdominal muscle in abdominal region. There were also fractures in the sternum and pelvis and a diffuse interstitial lung pattern in the right coxa-femoral luxation and the lungs. In the ultrasonographic examination, intestinal segments within the swelling at the line of the right lateral thorax were monitored. Ventral median laparotomy was performed on the patient under general anesthesia. Herniated intestines at the right paracostal region were placed back into the abdominal cavity and herniorrhaphy was performed. The abdominal cavity was closed according to the technique. As a result, paracostal hernia is a pathology that is rarely seen in cats after being hit by a car. Many operative techniques have been defined in hernia treatment. Median laparotomy was preferred for our patient and the hernia was treated successfully. This case report was prepared in order to contribute to our colleagues.

The article brings back to attention the La Tène coin hoard found (during the 70’s) at Sânnicolau Român (com. Cefa, Bihor county). The content of the hoard has only been partially recovered: 24 from circa 100 coins, one of them Toc-Chereluș type, and the others Medieșu Aurit type – group c. Using the relationship between these two type of coins, we reopen the discussion about the characteristics of Medieșu Aurit coins, and the issue of dating them in relation with the Toc-Chereluș scyphate.

The triumphal arches, a product of imperial propaganda, are the most famous and widespread Roman triumphal monuments. The official Roman coins illustrated on their reverse the triumphal arches located in the capital of the empire, Rome. Many of these monuments are still preserved, but some have disappeared in the tumult of history. Therefore, coins become “evidence” of the existence of these buildings when thy have not survived over centuries or allow the reconstruction of parts that have disappeared from them. The provincial coins of Lower Moesia also speak of the presence of such triumphal monuments (unknown now by of archaeological discoveries) from this border province. In this paper, some considerations are expressed regarding the numismatic evidence of the triumphal arches at Markianopolis and Tomis.

Despite recent increasing interest in the Ottoman materiality in Romania, local archaeological research continues to ignore its long biography, artificially separating the sites and objects from the present. No less problematic is the fact that heritage policies focus solely on the more “famous” Ottoman monuments built by the elites, while ignoring the “modest” architecture found, for example, in rural areas. In order to redress these shortcomings, this study looks at the long biography (from the Ottoman period up to the present day) of the Muslim cemetery in Lanurile in rural Dobruja (Bărăganu commune, Constanţa County), analysing it in relation to other material elements from the neighbouring village of Bărăganu. Ottoman documents mention these two villages by the names Osman-Facı and Ebeköyü, both being inhabited by Turks and Tatars and both part of the kaza of Mangalia. The two villages were renamed Bărăganu and Lanurile, respectively, after the inclusion of Dobruja in the Romanian state in 1878. Gradually – in particular during the 1970s and, increasingly, after 1990 – the inhabitants of these villages (Romanians and Turks/Tatars) began to migrate to nearby towns and cities (Basarabi, Medgidia and Constanţa) or to Turkey (in the case of Turks and Tatars). According to local testimony, this migration occurred simultaneously with the settlement in Bărăganu and Lanurile of many families from the Moldavia region. As a result of this massive depopulation, the Muslim cemeteries are the only remaining material legacy of the villages’ Ottoman past. Lanurile cemetery in particular reflects a genealogical depth (through the extensive and dense distribution of funerary monuments), an aspiration to enduring memory (through the monumentality and durability of the funerary stelae) and an image of eternity (through the monotony of the stones planted in the ground). This funerary space is at one and the same time a monument to a disappeared community, a necropolis in the process of becoming an archaeological site and still-functioning cemetery with a long biography. The present study thus seeks to examine the relationships between the materiality of the Ottoman heritage, the material memory of the Turkish and Tatar communities, local commemorative practices, and the social effects of modernity.
Građanska desnica 1984.- 1989. - prilog istraživanju tipologije unutarnjih neprijatelja socijalističke Jugoslavije
Authors: Marijan Davor
Published: September 2022

Popisu unutarnjega neprijatelja Socijalističke Federativne Republike Jugoslavije 1984. godine dodana je kategorija građanske
desnice pod kojom je komunistički režim podrazumijevao skupine i pojedince koji se u postjugoslavenskim interpretacijama
tretiraju kao kritička inteligencija. Zbog njezina intelektualnoga
sastava režim je građansku desnicu sredinom i u drugoj polovici 1980-ih godina smatrao svojim najopasnijim protivnikom.
Takva je ocjena bila uobičajeno pretjerivanje sustava koji je osporavanju svojih dogmi pridavao osjetno veće značenje no što
su to one doista bile. Na temelju dostupnih izvora, prvenstveno
gradiva Saveza komunista i službi sigurnosti, u ovom se radu pokušava odgovoriti na pitanje što je građanska desnica i koliko je
uopće bila utemeljena ta kategorija.
Ključne riječi: intelektualna povijest; Savez komunista Jugoslavije; socijalistička Jugoslavija; unutarnji neprijatelj; građanska
desnica; nacionalizam.
A LOGÍSTICA DE TRANSPORTE AGRÍCOLA MULTIMODAL DA REGIÃO OESTE PARANAENSE
Authors: Dalmás Sandra Regina da Silva Pinela , Lobo Débora da Silva , Freire da Rocha Jr Weimar
Published: September 2022

Este artigo compara as opções para o transporte de granéis agrícolas da região Oeste do Paraná. O propósito foi identificar as razões da pouca utilização da hidrovia em comparação à rodovia e ferrovia. A técnica de observação in loco foi realizada nos terminais fluvial e ferroviário, e de entrevistas não estruturadas, guiadas, com alguns profissionais responsáveis pela logística de empresas atuantes na comercialização de grãos da região. Utilizou-se de pesquisa documental para a coleta de dados secundários, referentes às características dos transportes e preços dos fretes. A análise do conteúdo foi feita por comparação entre os preços de fretes, perdas, e impacto nos custos relacionados aos problemas ambientais, de cada arranjo configurado. Constatou-se que a preferência pelo modal rodoviário ocorre principalmente devido à falta de infra-estrutura logística para os outros modais. Na comparação de desempenho portuário, o porto de Santos apresenta menor tempo médio de espera para atracamento dos navios, do que o Porto de Paranaguá. Concluiu-se que a utilização da hidrovia é uma alternativa para redução dos custos de transporte na região e há uma demanda latente na região por esforços conjuntos da iniciativa pública e privada para a solução das deficiências existentes no escoamento da produção agrícola da região Oeste do Paraná.
