Authors: DURGUN Recep
Published: August 2023

Urdu edebiyatında seyahatname türü her ne kadar yeni bir tür olsa da son asırda hatırı sayılır bir birikime sahiptir. Seyahatnameler seyahat edilen bölge ilgili önemli bir bilgi kaynağıdır. Bu eserler kültürler arası etkileşimde de önemli bir rol oynamaktadır. Pakistanlı ve Hindistanlı seyyahların XX. yüzyılda Türkiye’ye olan ilgileri artmıştır. Pakistan ve Hindistan’dan gelen seyyahların çoğu İstanbul’dan sonra en çok Konya’yı ziyaret etmişlerdir. Bunun en önemli sebebi Mevlana Celaleddin Rumi’ye olan sevgi ve bağlılıklarıdır. Bu seyyahların Konya’yı ziyaretinin temel amacı Rumi’nin türbesinin ziyaret ederek sevap kazanmaktır. Dolayısıyla Pakistanlı ve Hindistanlı seyyahların Türkiye seyahatnamelerinin Konya bölümleri Konya’nın coğrafi konumu, ekonomik, siyasi ve kültürel yapısı hakkında bilgi aktarmalarının yanında Mevlana ve Mevlevilik ile ilgili bilgileri içermesi açısından da önemli kaynaklardır. Teknolojik gelişim, seyahat araçlarının çeşitliliği sonucu seyahatlerin kolaylaşması, ticari faaliyetlerdeki çeşitlilik, düzenlenen ilmi kongrelerin yaygınlaşması ülkeler arasındaki insani hareketliliği artırmıştır. Buna paralel olarak Hindistan ve Pakistan’dan da Türkiye’ye gelen kişi sayısı artmıştır. Bunun doğal sonucu olarak seyahatnameler de artmıştır.

Published: August 2023

The insidious economic impact of water disruption has received less attention compared to palpable climate disasters, but climate change and water security concerns call for investigation on cost consequences of property values and business losses in an already fragile water supply-demand balance in many developing countries. The economic impact of frequent water supply disruptions from the Selangor River in Malaysia due to technical issues, water pollution, and climate-related problems was estimated using the stock flow measure to assess property at risk, and survey to estimate business loss. The findings revealed that commercial, residential, and industrial property valued at RM459,041 million in 2020 in the State of Selangor and parts of Kuala Lumpur were at risk due to frequent water supply disruptions. A survey of small and medium enterprises from the manufacturing, construction, and services sectors revealed that 46% of the respondents were affected with losses amounting to RM2,053 million. The total economic impact of water supply disruption in 2020, combining both property value at risk and business loss, amounted to RM461,094 million, which accounted for 34% of Malaysia's GDP. A number of recommendations are made to prevent the widespread occurrence of water disruptions.

Published: August 2023

Background:

Gastric teratoma (GT) occurs as a rule in infancy and is an extremely unusual gastric tumor in adult patients.

Case Presentation:

In this paper, we present the clinical and imaging findings of a 56-year-old female patient with a GT. The patient's main symptoms were increasing abdominal discomfort and pain. After the physical examination, she underwent ultrasound (US) and computed tomography (CT), which showed a large mass at the posterior wall of the stomach, and a teratoma was initially considered. After surgery, pathology confirmed the diagnosis of GT. The patient recovered after surgery and was discharged in good health. To the best of our knowledge, this study is the first reported case of gastric teratoma in an adult woman in the literature.

Conclusion:

Gastric teratoma of the adult period is a rare benign neoplasm that may have several complications; therefore, imaging is crucial for diagnosis and accurate treatment management. The aim of this study is to emphasize the value of US and CT in the diagnosis and treatment monitoring of mature gastric teratomas.

Superparamagnetic iron oxide nanoparticles have attracted attention due to
their compatibility with various biomedical applications. The quantum confinement
and increased surface area to volume ratio of the nanostructures alter their magnetic
properties. There are several bottom-up techniques to synthesize superparamagnetic
iron oxide nanoparticles; however, they offer certain limitations, like the existence of a
secondary phase. The reaction parameters can be controlled to form pure-phase
nanoparticles to increase their scope of applications in the field of medicine. Moreover,

Heilig geloof in wetgeving : Over geloven en wet(t)en in een democratische rechtsstaat
Authors: van Sasse van IJsselt Paul
Published: August 2023

De vrijheid van godsdienst en levensovertuiging is sterk verankerd in de Nederlandse (Grond)wetgeving. Deze vrijheid wordt regelmatig kritisch bevraagd in de Nederlandse pluriforme samenleving, als gevolg van secularisering, ontzuiling en concrete maatschappelijke gebeurtenissen. Paul van Sasse laat in zijn oratie zien dat deze bevraging soms leidt tot verandering van wetgeving, maar vooral tot aanhoudende druk op de vrijheid van godsdienst en levensovertuiging en daarmee op religieuze tolerantie. Dat kan anders in een democratische rechtsstaat. Van oudsher is de vrijheid van godsdienst, en sinds 1983 ook die van levensovertuiging, stevig verankerd in de Nederlandse (Grond)wetgeving. Deze vrijheid wordt regelmatig kritisch bevraagd in de Nederlandse pluriforme samenleving, als gevolg van secularisering, ontzuiling en concrete maatschappelijke gebeurtenissen, waarbij zorgen bestaan rondom integratie, veiligheid en de weerbaarheid van de democratie. Die bevraging vindt plaats ten aanzien van de vrijheid van godsdienst en levensovertuiging als zodanig, maar ook ten aanzien van de op grond van die vrijheid geldende wettelijke uitzonderingen op algemene regels, en de mogelijkheid tot uitoefening van die vrijheid. Aan de hand van drie categorieën wetgeving en vele voorbeelden wordt aangetoond dat concrete veranderingen in wetgeving vooralsnog grotendeels uitblijven, maar er wel een aanhoudende druk bestaat op de individuele en collectieve vrijheid van godsdienst en levensovertuiging en daarmee op religieuze tolerantie. Dat is met name het geval wanneer zij de omgang met orthodoxie betreft en wanneer de wetgever beoogt de democratische rechtsstaat te versterken. Daarbij ondergaat dit begrip een opmerkelijke betekenisverschuiving, wat indringende vragen oproept vanuit het perspectief van de constitutionele kwaliteit van wetgeving en de realisering van grondrechten als kernelement van diezelfde democratische rechtstaat. De relatie tussen overheid en religieuze organisaties verandert daardoor eveneens en maakt de Nederlandse pluriforme samenleving en democratische rechtsstaat kwetsbaar.

Allometric Equations for Estimating Above Ground Biomass of Sengon (Paraserianthes falcataria) in The Community Forest of Bateh Village, Magelang
Authors: Purwanto Ris Hadi , Azim Muhammad Tafakur
Published: August 2023

The above ground biomass of Sengon (Paraserianthes falcataria) in the community forest of Bateh Village were estimated by developing allometric equations. To establish the allometric equations, 400 sample trees were measured to determine the relationships between tree height (H) and stem diameter at breast height (D). Eighteen trees of various sizes were cut to measure the above ground biomass (stem, branch and leaves). The results showed that a diameter of 1.3m above the ground (D) alone was a good predictor of tree height (H). When D was combined with H, r2 was improved somewhat for stem, branch and leaves biomass. The relationships among measured tree dimensions drew a simple linear in log-log scale diagrams with r2 over 0.9699, suggesting the growth patterns of tree dimensions were closely interdependent, whereas the allometric equations between D and H was approximated by the hyperbolic relation with r2 over 0.9141. The individual tree equations appear to be applicable over a wide area of sengon in the community forest of Bateh Village, Magelang, Central Java.

The Chi Square test showed that bubulcus ibis selected several species as nest trees such as Gnetum gnemon L., Cassia siamea Lamk., Artocarpus heterophyllus Lamk., Calophyllum inophyllum L., Melia azedarach L., Antidesma bunius (L.) Spreng., and Dysoxylum gaudichaudianum(Juss.) Miq. Tree height, canopy height, canopy diameter and the distance from human disturbance showed a significant difference between used and non-used trees for the nest, however diameter breast high (DBH) and canopy openness of trees did not show significant differences. Habitat management of Bubulcus ibis should be improved by controlling its population that needed for the conservation of this bird species.

Effect of Gibberellins (GA4) on Germination Time and Height of Cendana (Santalum album Linn.) The hemiparasite Santalum album Linn. (cendana) grows very slow, in nature the rare and difficult seeds need stimulation to germinate. Gibberellins (including GA4) are growth regulators, usually used to increase growth as well as to break seed dormancy. The objectives of this research were to investigate the influence of gibberellins on germination percentage and height of cendana growth. Experiment was laid out in a Completely Randomized Design with 3 replicates of 300 seeds for germination percentage and 3 replicates of 10 seeds for seedling growth. Gibberellin was applied as treatment with 100, 300, and 500 ppm. The seed germination was recorded until 9 weeks, and height of plants measured until 8 months at the greenhouse. The results showed that the addition of gibberellins at all treatment increased the percentage of germination and caused the seeds germinated four weeks earlier than the control. In the first 4 months, 500 ppm gibberellins gave the highest acceleration of germination, afterward all treatments have relatively the same influences. Gibberellins gave positive effect on height of cendana growth. After 7 months, the growth decreased although all gibberellin treatments gave higher growth than the control.

Crown Model on Several Family of   9 years old  of Teak (Tectona grandis L.f) Progeny TrialCrown plays an important role in regulating the rate of tree growth through the photosynthesis process. Furthermore it can be used to measure stand density and to determine the availability of growing space. Because of the difficulty  and time consuming in direct crown measurement, the development of crown model is needed. The objectives of this study were to develop crown models of teak (Tectona grandis) of 9 years old from selected open pollinated families and to identifi) the variations of crown models among them.The study was conducted in an open pollinated progeny test located at the compartment 49a, RPH Sidowayah, BKPH Kedunggalar, KPH Ngawi. The experimental unit was family. Five families with the best average of stem diameter at breast height were selected as samples. Crown models were developed and variations of crown model were tested with analysis of variance.The crown model of teak can be divided into two sections. The upper crown representing the light crown section followed parabolic model while the under crown representing the shaded crown section followed linear model. No differences in crown model were found among families. The proposed models are:light crown section, paraboloid : Rl =1.91 * hl0.33shaded crown section, linear .. Rs = -0.75 + 0.57 hswhere Rl is light crown radius (m), hl is the height of light crown section (m), Rs is shaded crown radius (m) and hs is the height of shaded crown section (m)

The bamboo clumps tend to decrease due to the shift of used lands for residential or replaced by other crop comodities, which are considered more profitable. On the other hand, the need of bamboo for raw materials remain increase in line with population growth and the development of science. The important of the bamboo cultivation are to maintain the availability of its supply and to improve the quality of bamboo, which meet the market demands. This paper examined financial analysis of bamboo cultivation. Financial study was necessary to show whether the effort to cultivate bamboo is financially feasible or not. The data used were colecting from the research on bamboo plantation of PT XYZ company in Lampung. The results showed that the NPV (IDR 36,644,364.08) was greater than zero, the Net B/C ê-2.56 êwas greater than one, the IRR (11 %) was greater than the rate of 6%, and the payback period on the ninth year was less than the project life 15 years. Based on the criteria of financial study, it can be concluded that the cultivation of bamboo is financially feasible to be developed.

Bambu petung banyak digunakan untuk bahan konstruksi bangunan karena sifatnya yang keras dan kuat. Pembiakan secara vegetatif menggunakan rimpang (rhizome), namun memiliki kelemahan, yaitu kesulitan dalam pembongkaran rumpun bambu. Oleh karena itu digunakan stek cabang,lebih praktis, bahan stekter sedia lebih banyak, mudah diperoleh, murah, tidak merusak rumpun asal, waktu pengambilan lebih cepat, dan pembentukan rumpun lebih mudah. Media pengakaran yang umum digunakan adalah top soil, namun pengadaan top soil dalam jumlah besar sulit, sehingga perlu dicari alternatif lain yaitu dengan mencampur media top soil dengan media lain. Media yang digunakan yaitu media tanah, arang sekam dan kombinasi tanah+arang sekam (2:1). Stek cabang bambu petung dengan umur pohon induk ± 2 tahun, diameter 2-3 cm dan panjang 2 ruas. Panjang tunas pada perlakuan media tanah, arang sekam dan kombinasi tanah+arang sekam menunjukkan berbeda di antara perlakuan. Jumlah tunas terbanyak terdapat pada perlakuan media arang sekam dan kombinasi tanah+arang sekam (3 tunas). Media campuran tanah+arang sekam menunjukkan panjang tunas terpanjang (37,11 cm), dan panjang akar terpanjang (17,5 cm). Media tanah dan arang sekam menunjukkan % berakar terbesar (86,67 %).Kata kunci: stek cabang, bambu petung, media tanah, arang sekam, pembiakan vegetatif. Growth of branches of petung bamboo (Dendrocalamus asper) grafting in soil media, husk charcoal, and their combinationAbstractRecently, the utilization of bamboo is more extensive, but the attention towards its regeneration is not sufficient. The use of stem or branch cuttings are more practical and having more benefits and promising because the cutting materials are more available, easier to gain, cheaper, undamaging the source clump, faster in the taking time, and easier in the clump formation. The common rooting media used is top soil (the fertile part of upper layer soil). Recently, it is quite hard to provide top soil in a large number. Thus, it is important to find an alternative source in order to decrease the use of top soil that is by mixing the top soil media with other materials. The media used were soil media, husk charcoal, and the mixture of soil and husk charcoal (2:1). The branch cuttings used were branches of petung bamboo taken from 2 years old amboo, with 2-3 cm in diameter, and 2 nodus in length. The treatment was done by giving some variations in the soil media, the husk charcoal,and the mixture of soil and huskcharcoal. The mixture of soil and huskcharcoal media gave a significant influencet o the length of sprout variable,but it did not give significant influence to the number of sprout, the length of root, and the percentage of rooting.
