Menstruation is the regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina. It is characterized by the rise and fall of hormones. In women, various physical changes are brought about by fluctuations in hormone levels during menstrual cycle. Women may experience dysmenorrhea, amenorrhea, oligomenorrhea, menorrhagia, hypomenorrhea and UTI. Menstrual complications in school children. A prospective observational study was conducted for duration of 6 months, and study has been performed through an offline survey and 600 school children were recruited in our study according to inclusion criteria. By using data collection form student history was collected. The study has been performed through an offline survey and 600 school children were analysed using data collection form and student history interview. Out of 600 school individuals, students with dysmenorrhea 167(27.8%) individuals, oligomenorrhea 27(4.5%), hypomenorrhea 12(2%), anemia 1(0.1%), dysmenorrhea and anemia 7(1.1%), dysmenorrhea and menorrhagia 169(28.1%), dysmenorrhea, oligo and UTI 1(0.1%), dysmenorrhea, oligo and menorrhagia 26(5.2%), dysmenorrhea and UTI 10(1.6%), dysmenorrhea and hypomenorrhea 23(3.8%), dysmenorrhea, hypomenorrhea and anemia 2(0.3%), dysmenorrhea, oligo and anemia 2(0.3%), oligo and menorrhagia 6(1%), oligo and hypomenorrhea 37(6.1%), UTI 2(0.3%), menorrhagia 30(5%), oligo and anemia 14(2.3%). With our overall six months work, we concluded that oligomenorrhea, dysmenorrhea are the most common menstrual complications in school children during menstruation. The underlined cause to these complications is lack of proper nutrition, low BMI, and poor economic status. By conducting awareness programs in schools about menstruation and diet, basic knowledge has been provided, this may reduce further menstrual complications.

Osmanlı Devleti’nde cari hukuka göre gayrimüslim nüfus zımmî statüsünde yer almaktadır. Bu statü çerçevesinde de devlete karşı vergi yükümlülüklerini yerine getirirlerdi. Vergi yükümlülükleri içerisinde Gayrimüslimlere ilişkin en önemli kalem cizye vergisidir. Başlangıçta tahrir defterlerine kaydedilen veriler doğrultusunda hane esaslı olarak ödenen bu vergiler tahrirlerin uzun zaman aralıklarıyla yapılması nedeniyle mali yeterliliklerini yitirmeye başlamıştır. Merkezi idare vergi kaybını önlemek ve vergiye esas nüfusun kapsamını daha da genişleterek yeni bir düzenlemeye gitmiştir. Hane esaslı vergi uygulamasından vazgeçerek yaş aralığı ve geliri yeterli olan her bir Gayrimüslim neferden cizye vergisi almak yoluna gitmiştir. Bu doğrultuda muafiyeti olan gruplar da vergi mükellefi statüsüne geçmiştir. Böylece XVII. yüzyıl şartları içerisinde idari bir tasarrufla cizye defterleri yeni bir forma sokulmuştur. Bu uygulama nedeniyle Osmanlı coğrafyası içerisinde yer alan idari birimlerde yeni cizye defterleri tanzim edilmiştir. Bölgesel farklılıklara rağmen genel itibariyle fakir (edna), evsat (orta), âlâ (yüksek) kategorileri altında mükelleflerin din, isim, eşkâl, meslek özellikleri kaydedilmiştir.
Bu çalışmada Sivas, Sivasili, Tokat, Niksar, Zile kazaları için tutulan cizye tahrir defteri içerisinde nefs-i Tokat’a ilişkin düzenlenen cizye kayıtları değerlendirilmiştir. Bu kayıtlar üzerinden Tokat kaza merkezindeki mahalleler, bu mahallelerde yaşayan Gayrimüslimlerin dini aidiyetleri, isimleri, eşkâlleri, meslekleri ve ödedikleri cizye miktarları tespit edilmiştir. Elde edilen veriler ışığında XVII. yüzyılın son çeyreğinde Tokat’ın sosyal, ekonomik ve dini yapısı hakkında mukayeseli değerlendirmeler yapılmıştır.

Resumo- Convolução é uma maneira de se combinar dois sinais para se obter um terceiro sinal. É uma importante técnica em sistemas lineares. Utilizando a estratégia da decomposição de um impulso, os sistemas são descritos por um sinal chamado de resposta ao impulso. Convolução é importante porque relaciona três sinais de interesse: o sinal de entrada, o sinal de saída e a resposta ao impulso. A operação inversa da convolução é as vezes conhecida como deconvolução. Neste trabalho falamos de deconvolução, a operação inversa à convolução. Apresentamos a teoria generalizada e um breve estudo de caso com e sem ruído.

Fluid Temperature of Geothermal Energy Wells Converted from Abandoned Oil/Gas Wells
Authors: Zhang P. , Guo B. 
Published: October 2023

Abstract
The transition from fossil energy to clean energy is an ongoing trend. Because geothermal energy is buried beneath oil /gas wells, it is desirable to convert abandoned oil/gas wells to geothermal energy wells. The candidate wells can be dry holes in oil/gas exploration or end-of-life oil/gas wells in depleted oil/gas reservoirs. There is a knowledge gap to fill between the oil/gas wells and geothermal wells in the well conversion engineering, that is, factors affecting the performance of the geothermal wells are not fully understood. The mathematical model developed by Wei and Guo (2023) was used in this work to investigate the factors affecting the temperature of produced water of geothermal energy wells converted from abandoned oil/gas wells. Both vertical and horizontal well options were considered. The result of the field case study using the data for a well in the Songliao Basin of Northeastern China shows that, without pipe insulation, the temperature of the returned water is very close to that of the injected water, regardless of vertical or horizontal wells. With pipe insulation, the temperature of the returned water in the horizontal well is higher than that in the vertical well. The temperature of the returned water declines quickly as the thermal conductivity of pipe insulation increases in the low-thermal conductivity region. The temperature of the returned water in horizontal wells is affected by the horizontal hole section length for heat transfer. But this effect levels off after about 1,000 m of horizontal hole section is reached, meaning that 1,000 m of horizontal hole section is adequate for heat transfer from the geothermal zone to the injected water. This paper provides an analytical method for the technical feasibility assessment of converting abandoned oil/gas wells to geothermal energy wells.

Published: October 2023

Over the last decades, it has been shown that teaching and learning statistics is complex, regardless of the teaching methodology. This research presents the different learning profiles identified in a group of future Primary Education (PE) teachers during the study of the Statistics block depending on the methodology used and gender, where the sample consists of 132 students in the third year of the PE undergraduate degree in the University of the Basque Country (Universidad del País Vasco/Euskal Herriko Unibertsitatea, UPV/EHU). To determine the profiles, a cluster analysis technique has been used, where the main variables to determine them are, on the one hand, their statistical competence development and, on the other hand, the evolution of their attitude towards statistics. In order to better understand the nature of the profiles obtained, the type of teaching methodology used to work on the Statistics block has been taken into account. This comparison is based on the fact that the sample is divided into two groups: one has worked with a Project Based Learning (PBL) methodology, while the other has worked with a methodology in which theoretical explanations and typically decontextualized exercises predominate. Among the results obtained, three differentiated profiles are observed, highlighting the proportion of students with an advantageous profile in the group where PBL is included. With regard to gender, the results show that women's attitudes toward statistics evolved more positively than men's after the sessions devoted to statistics in the PBL group.
Foreign Bias in the Global Portfolio Investment of Selected OIC Countries
Authors: Md Elias Nura Lina 
Published: October 2023

Home bias reflects the propensity of investors to invest substantially in the domestic market. When investing abroad investors exhibit foreign bias, a tendency to overweight certain foreign markets based on their preferences. A thorough review of the literature reveals that foreign bias has not been thoroughly investigated in emerging countries, especially in the context of OIC countries. The purpose of this research is to examine the determinants of foreign bias in the global portfolio investment of selected OIC countries. An unbalanced bilateral panel data of 12 OIC countries’ outward equity investment in 74 host countries from the year 2001 to 2016 is analyzed. Cross-sectional analysis shows that OIC countries exhibit higher foreign bias towards their OIC counterparts especially in the MENA region. The results suggest, OIC countries not only exhibit foreign bias but also demonstrate regional bias. System Generalized Method of Moments (GMM) empirically shows that foreign bias is possibly explained by factors related to financial market openness, familiarity, information asymmetry, and global financial crisis. This study has a significant implication for the investors, fund managers and the regulators of the OIC countries. Investors and fund managers in OIC countries should be aware of the existence of foreign bias in their global portfolio investment that may potentially reduce the benefits of optimal diversification. It is a call for policymakers in the OIC countries to convince their local investors that international portfolio diversification offers risk sharing and eventually increases investment return.

One of the efforts to control weeds in preparing land for lowland rice cultivation with the No-Tillage system one of which uses isopropylamineglyphosate herbicide. The purpose of this study was to determine the dose of glyphosate herbicide that effectively controls weeds for preparation of lowland rice planting with the no tillage system, to determine changes in weed composition in lowland rice after the application of glyphosate herbicide, and to determine the effect of the no tillage system after the application of glyphosate herbicide on growth and paddy yields. Data collection was carried out from June to September 2022 in the rice fields of Trimurjo District, Central Lampung Regency and the Weed Science Laboratory, Faculty of Agriculture, University of Lampung. The treatment was arranged using a randomized block design with 4 replications and 6 treatments consisting of the glyphosate herbicide doses (1,080; 1,440; 1,800; 2,160 g/ha) + no tillage, manual weeding, and intensive tillage system. Homogeneity of variance was tested by Barlett's test and then analyzed for variance. Separation of the mean was carried out using the least significant difference test (LSD) at the 5% level. The results showed that the herbicide isopropylamine glyphosate doses of 1,800 and 2,160 g/ha of the no tillage system could be used to replace the intensive tillage system because it was effective in controlling total weeds, sedges, grasses, and broad leaf groups, dominant weed Fimbristylis miliacea, Echinochloa colonum, Ludwigia octovalvis and Monochoria vaginalis up to 6 WAP, causing a change in the composition of weed species from Echinochloa colonum become monochoria vaginalis at 3 WAP, and from Echinochloa colonum become Ludwigia octovalvis at 6 WAP. The growth is not stunted and yield of lowland rice plants is equivalent to the intensive tillage system with grain yields per hectare of 5.14 - 5.49 t/ha.

Published: October 2023

Pineapple (Ananas comosus [L.] Merr) is one of the potential horticultural commodities and is a mainstay of exports in Indonesia. Pineapple fruit productivity can be increased through the fertilization process. One of the fertilization processes in pineapple plants is fertilization after forcing. The nutrients needed by pineapple plants after forcing are nitrogen and potassium which can support plant growth and increase pineapple fruit production. The purpose of this study was to determine the effect of the frequency of fertilization after forcing and to find out which treatment had the highest productivity. The research was conducted from October 2022 to April 2023 at the Central Lampung Pineapple Plantation, Lampung Province. This study used a single factor randomized block design (RBD), namely the frequency of fertilization on the day after forcing (HSF). The treatment consisted of four levels, namely twice fertilization given at 20 and 55 HSF (P1), two times fertilization given at 15 and 30 HSF (P2), three times fertilization given at 15, 30, 45 HSF (P3) and four times of fertilization given at 15, 30, 45, 60 HSF (P4). Each fertilization application uses Urea 50 kg/ha and K2SO4 75 kg/ha. Each treatment was repeated four times to obtain 16 experimental units. The results showed that the frequency of fertilization after forcing had an effect on the weight of 12 eyed fruit, the length of 11 and 12 eyed fruit, the diameter of 12 eyed fruit, and the weight of 12 eyed crowns in pineapple plants. The fertilization that was able to produce the best pineapple fruit productivity was fertilization with twice the frequency at 15 HSF and 30 HSF which produced the highest production potential compared to the control treatment with a difference of 2.51%.Keywords : pineapple, fertilization, HSF (Days After Forcing)

Bean (Phaseolus vulgaris L.) is generally cultivated in monoculture (sole cropping) by farmers in the highlands as main crops. Increasing land use efficiency (LUE) by inter-cropping sorghum on bean requires certain cultivation techniques so as not reducing the production of seeds or fresh fruit bean. This experiment aimed at determine 1) the yields of seeds and fresh pods harvested from the bean-sorghum intercropping compared to those from the sole cropping and 2) the LUE of the bean-sorghum intercropping. The research, which was conducted during April-September 2021 in Sekincau District, West Lampung Regency, Lampung Province, Indonesia used dwarf beans Balitsa-2 variety and climbing bean Horti-3 variety, each of which to be intercropped with sorghum of Numbu variety. Five levels of cropping system treatment were arranged in a Completely Randomized Block Design (CRBD) with six groups as six replications. The results showed that there was no difference the seeds yield and fresh pods of bean between those harvested from bean-sorghum intercropping and from monocultures. The seed yield harvested from the dwarf bean-sorghum intercropping was higher, whereas those harvested from the climbing bean-sorghum intercropping was lower, respectively, compared to those harvested from the monoculture. In producing fresh pods, intercroppings of dwarf bean-sorghum and climbing bean-sorghum increased the LUE, respectively. Whereas in producing seeds, the dwarf bean-sorghum intercropping increased the LUE, but the climbing bean-sorghum intercropping decreased the LUE.
