Since the lacrimal puncta are moved away from the eyeball, the tear elimination is difficult, tears are always present. Materials and Methods: This study includes patients suffering from senile ectropion, who were treated surgically at Polyclinic “SHOSHI” in Prishtina. Our study includes 19 patients suffering from senile ectropion, out of which, 17 were older than 75 years old and in those patients the ectropion was preset on both lower eyelids, while 2 patients were under 75 years old and the ectropion was present only on one side lower eyelid. Prior to surgery, patients have undergone laboratory examinations. The surgery was performed under local anesthesia. The suturing was done in three layers using 6.0 vicryl sutures. No operative or post-operative complications were encountered. Purpose: The purpose of this case report study is to show the success of the surgical treatment of ectropion, a procedure that is mainly performed so the tear elimination is enabled, and there are no tears present constantly. Conclusion: In old patients where the eyelid is turned outwards its margin, conjunctiva is constantly irritated, thickened and dry, the best method of treatment is the surgical treatment, making it possible for the tears to drain properly.展开更多

The semi-lunar fold is located in the interior angle of the eye, and represents the third rudimentary eyelid. In the histological aspect, conjunctiva is composed of the epithelium and stroma. Thestroma is divided into two parts: the superficial adenoid part and the inner fibrotic part. The accessory lacrimal glands are found in the stroma. Materials and methods: A case study of a 14 year-old male patient, who came at our clinic as a result of a 5 - 6 mm tumefaction on the bulbar conjunctiva, on the nasal part of the bulbar conjunctiva, attached to the semi-lunar fold. The patient referred that the cyst appeared 6 - 7 months ago and was constantly growing. In the beginning the patient has been treated with antibiotic and corticosteroid eye drops. However, the cyst grew constantly therefore the best solution was the surgical treatment. The surgery was performed under local anesthesia. The total excision of the cyst was performed. The removed tumefaction was then diagnosed as a cyst of the conjunctival stroma. Purpose: The purpose of this study is to show that the best treatment of the conjunctival epithelium tumefaction, which is not reduced in size by the local treatment with antibiotics and corticosteroids, is the surgical treatment. Conclusion: Every change in the conjunctiva, causing functional and aesthetic problems, is an issue that should be directed to the ophthalmologist. Such changes should be treated with medications or surgically, the patient should be followed up, to see whether or not such changes will reappear.展开更多

The period is characterized by a liberal approach toward the development of the region. Such development of Kosovo was evident in all spheres of life, including architecture, which functions as an integral part of a society and its progress. This progress was ＂supported＂ with an intention to overpower the existing architectural environment and the overall identity of the region in some way. However, when this progress was realized wherein numerous buildings considered important were materialized, an intention to have the earlier and ＂original＂ spatial structures to be replaced became evident. In the case of Kosovo, the term ＂liberal＂ can be understood negatively and positively. From the architectural viewpoint, desi^Ins tend to follow technological advances and ＂trends＂ of the time. Consequently, the materialization of such buildings, which are surrounded by symbolisms related to different types of identity and leading toward regional modernism, is an important part to emphasize. The current study aims to consider important thoughts about architectural identity and its categories in general but specific to the context of Kosovo. The history of the region has a critical story of influences toward its formation. Although several philosophies were accepted by the mass, others produced the antidote of the actual input. This study considers theimportance of finding the best possible interpretation of Kosovo＇s architectural identity, such that Kosovo can be well known in the future as it was in the past.展开更多

They are of submucosal or extremely rare subserosal origin. Although most gastric lipomas are usually detected incidentally, they can cause abdominal pain, dyspeptic disorders, obstruction, invagination, and hemorrhages. Subserosal gastric lipomas are rarely symptomatic. There is no report on treatment of subserosal gastric lipomas in the English literature. We present a case of a 50-year-old male with symptomatic subserosal gastric lipoma which was successfully managed with removal, enucleation of lipoma, explorative gastrotomy and edge resection for histology check of gastric wall. The incidence of gastric lipoma, advanced diagnostic possibilities and their role in treatment modalities are discussed.展开更多

The lowest mean doubling time was observed for 2% cellobiose, followed by a combination of 2% fructooligosaccharide (FOS) with 2% cellobiose, while during storage at 4℃ for 4 weeks of fermented milk, no significant differences were observed between fermented milk supplemented with 2% cellobiose and 2% FOS. The highest viability retention during storage was observed for the combination of the two prebiotics, cellobiose and FOS. The results indicate that, in milk supplemented with cellobiose or a combination of cellobiose and FOS, Bifidobacterium infantis remain viable during 4 weeks of storage, suggesting the usefulness of cellobiose as a prebiotic ingredient in fermented products involving bifidobacteria.展开更多

A substantial percentage of patients who ex- perience ACS is more than 75 years old, and they represent the fastest-growing segment of the population treated in this setting. These pa- tients present different patterns of responses to pharmacotherapy, namely, a higher ischemic and bleeding risk than do patients under 75 years of age. Our aim was to identify whether the currently available ACS ischemic and bleeding risk scores, which has been validated for the general population, may also apply to the elderly population. The second aim was to determine whether the elderly benefit more from a spe- cific pharmacological regimen, keeping in mind the numerous molecules of antiplatelet and antithrombotic drugs, all validated in the general population. We concluded that the GRACE （Global Registry of Acute Coronary Events） risk score has been extensively validated in the elderly. However, the CRUSADE （Can Rapid risk stratification of Unstable angina patients Suppress ADverse outcomes with Early imple- mentation of the ACC/AHA Guidelines） bleeding score has a moderate correlation with outcomes in the elderly. Until now, there have not been head-to-head scores that quantify the ischemic versus hemorrhagic risk or scores that use the same end point and timeline （e.g., ischemic death rate versus bleeding death rate at one month）. We also recommend that the frailty score be considered or integrated into the current existing scores to better quantify the overall patient risk. With regard to medical treatment, based on the subgroup analysis, we identified the drugs that have the least adverse effects in the elderly while maintaining optimal efficacy.展开更多

Coordinated semi-actuated control due to ability to respond traffic demands on both main and secondary directions, based on road detector registration saves the coordinated features, serving the unused time to the main road, while the secondary clears early. In this paper, the authors analyzed and explained comparatively the results of LOS （level of service） parameters of the current state of control （fixed-time） with the proposed control （semi-actuated coordinated） of the artery of length 2,348 km consisted of four signalized T intersections. Highway Capacity Manual and Synchro/Sim Traffic software are used for analysis and optimization of parameters in this paper.展开更多

Materials and Methods: Forty-five mature maxillary and mandibular anterior teeth, extracted for periodontal reasons, were collected. After the chemo-mechanical instrumentation of the root canal, teeth were filled with four endodontic sealers (Endomethason, AH+, Canason and Apexit). Depending on canal sealers and the CEJ (Cement Enamel Junction), teeth were divided into 8 experimental groups (n = 5) and one control group/CG (n = 5). Teeth color changes (L*a*b*/CIE Commission Internationaled’ Eclaraige) were determinated by a spectrophotometer Vita Easyshade in 4 stages (Baseline, Week 0, 4 and 12). Results: Between the EOCEJ and CG for the parameter L*, there was a statistical significance (p 0.05). The L*a*b* results were: L* (83.6 ± 4.8 → 83.6 ± 4.9);a* (﹣2.68 ± 1.02 → ﹣1.12 ± 0.72) and b* (20.2 ± 4.5 → 24.4 ± 4.2). Conclusions: All endodontic sealers may cause teeth discoloration.展开更多

In addition, irresponsible and incorrect selection of sites for industrial and municipal dumps, which are often located in vicinity or on actual river banks, contributes significantly to environmental pollution. Analysis of the leachate from such sites was done by direct sampling and by using TCLP (Toxicity Characteristic Leashing Procedures) method. Based on the analysis of physicochemical parameters of the filtrated water from the sites Zitkovac, Grabovac and Balaban and analysis of the samples of surface water and groundwater from the site Grabovac, possible steps for removal and reduction of the existing pollution were proposed. Potential permanent solution in form of purification of municipal and industrial waste waters as well as leachate from illegal landfills was suggested. The potential implementation of remediation with a unified system for water purification, by using Membrane Bio Reactor (MBR), which includes the process of stabilization/solidification of a residual sludge, would have as an end product a neutral powder material completely safe for the environment, suitable for a variety of applications.展开更多

Shown in percentage, only 39.2% （765,125） of inhabitants live in urban areas. The focus is to work and find the best and cheap solutions for the 60.8% （1,173,370） of inhabitants of the country which live in rural areas. From this number only 42% of them have access to the sewage network while 60.8% of them have implemented individual solutions （latrines） without any treatment, leading to a large pollution of the water bodies. The existing rural sewage networks are built only with septic tanks, poorly designed and do not fulfill the wastewater treatment criteria. Regarding this issue, the Kosovan legislation concerns only urban areas （settlements of more than 2,000 inhabitants） and is expected to be completed in 2014 for rural areas according to the EU （European Union） directive for wastewater discharge. As a pilot project, the CDI （community development initiatives） started with WWTP （waste water treatment plants） based on the Vertical Constructed Wetland option （french model） as it appears to be the most adapted option in this rolling, rural, and temperate climate context, implementing this kind of treatment in 3 villages for the first time in Kosovo. Through this, it is interesting to take a perspective on all the phases of these projects starting from feasibility reports, project design to concept and modalities of implementation and options for operation and maintenance, in order to assess how this technical option is feasible and replicable in the country at a large scale. It finally appears that the potential for constructed wetland in the Balkan region is promising as it provides a simple solution for most of the regional constraints, but requires skills to be developed locally for designing and building as well as a deeper consideration in the national regulation.展开更多

This paper makes a comparative study between a ＂solid＂ and a ＂waffle＂ slab system. A typical 14-story RC building structure is selected as an example for this study purpose. The first part of this study is focused in deriving an optimal solution for a solid and waffle slab system which are later on considered as constituents of all stories of the 14-story building. In the second part, it is elaborated the effect of both slab systems over the 14-story building model. This study aims to emphasize the advantages of mid-rise buildings constituted of waffle slab system over the buildings characterized with solid types of slabs, in terms of economy, structural safety and performance.展开更多

The aim of present investigation was carried out to study genetic variability of quantitative and qualitative parameters. The populations from SL-2 were characterized of higher significance on seed oil （23.74%） and protein content （16.74%）. The estimation average value of seed protein and oil content was 15.52% and 23.48% respectively. The variability of plant height ranged from 182.33 cm to as much as 200.89 cm, while distinction＇s between them were ＋ 18.56 cm which was a significant higher at P〈0.05 probability level. The SL-3 showed the higher value of HWK （34.6 g）, head per plant （39.33） and head diameter （9.5 cm） but, was characterized significantly lowest on seed protein content （13.99%）. The all traits included in our investigations showed a higher genetic variability with majority of extreme values. The sunflower populations differed significantly in several parameters measured, they have a different genetic and morphological backgrounds. Results from wild sunflower form indicated notable differences in dispersion of important genes for different traits and showed the potential for using in future for breeding program.展开更多

Methods: Forty extracted single rooted human teeth stored in 0.5% saline were used. Periodontal soft tissues were removed followed by crown separation at the CEJ. All the teeth were randomly divided into two groups. Manually Instrumented Group 1 was irrigated with 5.25% NaOCl and 17% EDTA alternately, same as Ultrasonically Instrumented Group 2. The controls for both groups were irrigated with saline solution. Results: Ultrasonic instrumentation and the combined use of two different solutions (5.25% NaOCl and 17% EDTA) yielded better results on smear removal. Conclusions: Irrigation with 17% EDTA followed by 5.25% NaOCl was successful in complete removal of smear layer on cervical and middle thirds of the root canals. Ultrasonic instrumentation was slightly more successful on the apical one third of the root canals.展开更多

文摘The effects of cellobiose, fructooligosaccharide and their combination on fermentation of skim milk by probiotic Bifidobacterium infantis were evaluated using mean doubling time as a parameter for sustaining growth. The lowest mean doubling time was observed for 2% cellobiose, followed by a combination of 2% fructooligosaccharide (FOS) with 2% cellobiose, while during storage at 4℃ for 4 weeks of fermented milk, no significant differences were observed between fermented milk supplemented with 2% cellobiose and 2% FOS. The highest viability retention during storage was observed for the combination of the two prebiotics, cellobiose and FOS. The results indicate that, in milk supplemented with cellobiose or a combination of cellobiose and FOS, Bifidobacterium infantis remain viable during 4 weeks of storage, suggesting the usefulness of cellobiose as a prebiotic ingredient in fermented products involving bifidobacteria.
文摘Ethnobotanical studies in the Balkans are crucial for fostering sustainable rural development in the region and also for investigating the dynamics of change of Traditional Ecological Knowledge(TEK),which has broad-sweeping implications for future biodiversity conservation efforts.A survey of local botanical and medical knowledge and practices was conducted in four mountainous villages of the Peshkopia region in northeast Albania,near the Macedonian border.Snowball sampling techniques were employed to recruit 32 informants for participation in semi-structured interviews regarding the use of the local flora for food,medicinal,veterinary and ritual purposes.The uses of 84 botanical taxa were recorded as well as a number of other folk remedies for the treatment of both humans and livestock.Comparison of the collected data with another ethnobotanical field study recently conducted among Albanians living on the Macedonian side of Mount Korab shows a remarkable divergence in medicinal plant uses,thus confirming the crucial role played by the history of the last century in transforming TEK.Most noteworthy,as a legacy of the Communist period,a relevant number of wild medicinal taxa are still gathered only for trade rather than personal/familial use.This may lead to unsustainable exploitation of certain taxa(i.e.Orchis and Gentiana spp.) and presents some important conservation challenges.Appropriate development and environmental educational frameworks should aim to reconnect local people to the perception of limitation and renewability of botanical resources.
文摘Age is an important prognostic factor in the outcome of acute coronary syndromes （ACS）. A substantial percentage of patients who ex- perience ACS is more than 75 years old, and they represent the fastest-growing segment of the population treated in this setting. These pa- tients present different patterns of responses to pharmacotherapy, namely, a higher ischemic and bleeding risk than do patients under 75 years of age. Our aim was to identify whether the currently available ACS ischemic and bleeding risk scores, which has been validated for the general population, may also apply to the elderly population. The second aim was to determine whether the elderly benefit more from a spe- cific pharmacological regimen, keeping in mind the numerous molecules of antiplatelet and antithrombotic drugs, all validated in the general population. We concluded that the GRACE （Global Registry of Acute Coronary Events） risk score has been extensively validated in the elderly. However, the CRUSADE （Can Rapid risk stratification of Unstable angina patients Suppress ADverse outcomes with Early imple- mentation of the ACC/AHA Guidelines） bleeding score has a moderate correlation with outcomes in the elderly. Until now, there have not been head-to-head scores that quantify the ischemic versus hemorrhagic risk or scores that use the same end point and timeline （e.g., ischemic death rate versus bleeding death rate at one month）. We also recommend that the frailty score be considered or integrated into the current existing scores to better quantify the overall patient risk. With regard to medical treatment, based on the subgroup analysis, we identified the drugs that have the least adverse effects in the elderly while maintaining optimal efficacy.
文摘Fixed-time control of traffic signals pursues the regulation of phases based on historical data of traffic demand, in this way, neglecting of the random arrival rates of traffic flow on different intersection streams causes increasing of the stops and delays and fuel consumption at the same time. Coordinated semi-actuated control due to ability to respond traffic demands on both main and secondary directions, based on road detector registration saves the coordinated features, serving the unused time to the main road, while the secondary clears early. In this paper, the authors analyzed and explained comparatively the results of LOS （level of service） parameters of the current state of control （fixed-time） with the proposed control （semi-actuated coordinated） of the artery of length 2,348 km consisted of four signalized T intersections. Highway Capacity Manual and Synchro/Sim Traffic software are used for analysis and optimization of parameters in this paper.
文摘Machine learning has emerged as a pivotal tool in deciphering and managing this excess of information in an era of abundant data.This paper presents a comprehensive analysis of machine learning algorithms,focusing on the structure and efficacy of random forests in mitigating overfitting—a prevalent issue in decision tree models.It also introduces a novel approach to enhancing decision tree performance through an optimized pruning method called Adaptive Cross-Validated Alpha CCP(ACV-CCP).This method refines traditional cost complexity pruning by streamlining the selection of the alpha parameter,leveraging cross-validation within the pruning process to achieve a reliable,computationally efficient alpha selection that generalizes well to unseen data.By enhancing computational efficiency and balancing model complexity,ACV-CCP allows decision trees to maintain predictive accuracy while minimizing overfitting,effectively narrowing the performance gap between decision trees and random forests.Our findings illustrate how ACV-CCP contributes to the robustness and applicability of decision trees,providing a valuable perspective on achieving computationally efficient and generalized machine learning models.
文摘Objective: The aim of this study was to investigate, in vitro, the color changes of the teeth, induced by endodontic sealers. Materials and Methods: Forty-five mature maxillary and mandibular anterior teeth, extracted for periodontal reasons, were collected. After the chemo-mechanical instrumentation of the root canal, teeth were filled with four endodontic sealers (Endomethason, AH+, Canason and Apexit). Depending on canal sealers and the CEJ (Cement Enamel Junction), teeth were divided into 8 experimental groups (n = 5) and one control group/CG (n = 5). Teeth color changes (L*a*b*/CIE Commission Internationaled’ Eclaraige) were determinated by a spectrophotometer Vita Easyshade in 4 stages (Baseline, Week 0, 4 and 12). Results: Between the EOCEJ and CG for the parameter L*, there was a statistical significance (p 0.05). The L*a*b* results were: L* (83.6 ± 4.8 → 83.6 ± 4.9);a* (﹣2.68 ± 1.02 → ﹣1.12 ± 0.72) and b* (20.2 ± 4.5 → 24.4 ± 4.2). Conclusions: All endodontic sealers may cause teeth discoloration.
文摘Direct discharge of municipal and industrial waste waters and leachate (originating from the illegal landfills) into recipients without prior purification is unfortunately very common practice in the region of northern Kosovo. In addition, irresponsible and incorrect selection of sites for industrial and municipal dumps, which are often located in vicinity or on actual river banks, contributes significantly to environmental pollution. Analysis of the leachate from such sites was done by direct sampling and by using TCLP (Toxicity Characteristic Leashing Procedures) method. Based on the analysis of physicochemical parameters of the filtrated water from the sites Zitkovac, Grabovac and Balaban and analysis of the samples of surface water and groundwater from the site Grabovac, possible steps for removal and reduction of the existing pollution were proposed. Potential permanent solution in form of purification of municipal and industrial waste waters as well as leachate from illegal landfills was suggested. The potential implementation of remediation with a unified system for water purification, by using Membrane Bio Reactor (MBR), which includes the process of stabilization/solidification of a residual sludge, would have as an end product a neutral powder material completely safe for the environment, suitable for a variety of applications.
文摘Republic of Kosovo has 1,304 settlements from which only 37 are urban and 1,267 are rural. Shown in percentage, only 39.2% （765,125） of inhabitants live in urban areas. The focus is to work and find the best and cheap solutions for the 60.8% （1,173,370） of inhabitants of the country which live in rural areas. From this number only 42% of them have access to the sewage network while 60.8% of them have implemented individual solutions （latrines） without any treatment, leading to a large pollution of the water bodies. The existing rural sewage networks are built only with septic tanks, poorly designed and do not fulfill the wastewater treatment criteria. Regarding this issue, the Kosovan legislation concerns only urban areas （settlements of more than 2,000 inhabitants） and is expected to be completed in 2014 for rural areas according to the EU （European Union） directive for wastewater discharge. As a pilot project, the CDI （community development initiatives） started with WWTP （waste water treatment plants） based on the Vertical Constructed Wetland option （french model） as it appears to be the most adapted option in this rolling, rural, and temperate climate context, implementing this kind of treatment in 3 villages for the first time in Kosovo. Through this, it is interesting to take a perspective on all the phases of these projects starting from feasibility reports, project design to concept and modalities of implementation and options for operation and maintenance, in order to assess how this technical option is feasible and replicable in the country at a large scale. It finally appears that the potential for constructed wetland in the Balkan region is promising as it provides a simple solution for most of the regional constraints, but requires skills to be developed locally for designing and building as well as a deeper consideration in the national regulation.
文摘In order to maximize the return of investments and at the same time improve the quality in the construction industry of midrise buildings, it is very important to derive an optimal solution to the building structural system, which would facilitate faster and easier construction activities with minimal quantity of construction material, while maintaining the satisfactory level of building safety and performance. This paper makes a comparative study between a ＂solid＂ and a ＂waffle＂ slab system. A typical 14-story RC building structure is selected as an example for this study purpose. The first part of this study is focused in deriving an optimal solution for a solid and waffle slab system which are later on considered as constituents of all stories of the 14-story building. In the second part, it is elaborated the effect of both slab systems over the 14-story building model. This study aims to emphasize the advantages of mid-rise buildings constituted of waffle slab system over the buildings characterized with solid types of slabs, in terms of economy, structural safety and performance.
文摘Our expedition have identified location in the central part of Kosovo where were collected a samples （accessions） at coordinates; Sub-Locality SL-1 （N42°34′36″, E21°07′45″）, altitude 574 m, SL-2 （N42°34′29″, E 21°07′45″altitude 591 m and SL-3 （N42°34′30″, E21°07′46″） on altitude 565 m. The aim of present investigation was carried out to study genetic variability of quantitative and qualitative parameters. The populations from SL-2 were characterized of higher significance on seed oil （23.74%） and protein content （16.74%）. The estimation average value of seed protein and oil content was 15.52% and 23.48% respectively. The variability of plant height ranged from 182.33 cm to as much as 200.89 cm, while distinction＇s between them were ＋ 18.56 cm which was a significant higher at P〈0.05 probability level. The SL-3 showed the higher value of HWK （34.6 g）, head per plant （39.33） and head diameter （9.5 cm） but, was characterized significantly lowest on seed protein content （13.99%）. The all traits included in our investigations showed a higher genetic variability with majority of extreme values. The sunflower populations differed significantly in several parameters measured, they have a different genetic and morphological backgrounds. Results from wild sunflower form indicated notable differences in dispersion of important genes for different traits and showed the potential for using in future for breeding program.
文摘Aim: The objective of this study was to evaluate the effectiveness of manual and ultrasonic instrumentation with varying irrigation protocols on removal of the smear layer from root canal walls. Methods: Forty extracted single rooted human teeth stored in 0.5% saline were used. Periodontal soft tissues were removed followed by crown separation at the CEJ. All the teeth were randomly divided into two groups. Manually Instrumented Group 1 was irrigated with 5.25% NaOCl and 17% EDTA alternately, same as Ultrasonically Instrumented Group 2. The controls for both groups were irrigated with saline solution. Results: Ultrasonic instrumentation and the combined use of two different solutions (5.25% NaOCl and 17% EDTA) yielded better results on smear removal. Conclusions: Irrigation with 17% EDTA followed by 5.25% NaOCl was successful in complete removal of smear layer on cervical and middle thirds of the root canals. Ultrasonic instrumentation was slightly more successful on the apical one third of the root canals.
