Prolonged labor is a complication that increases maternal and fetal mortality. Hypnopressur is a therapy that is being developed to treat pain and length of labor. The aim of this study was to prove that hypnopressur is more effective in shortening the duration of active phase I primigravida labor. The study design was randomized control trial. The research subjects were 80 divided into 4 groups: hypnopressure group (HP) n=20, hypnotherapy (HA) n=20, acupressure (AK) n=20 and control group (K) n=20 Intervention in the active phase of the first stage of labor. Statistical test using Wilcoxon, Kruskal Wallis, and Treatment Effect Analysis Test (RR, RRR, ARR). Hypnopressur (HA) was effective in shortening the length of labor compared to hypnoaudio, acupressure and deep breathing supported by the median value of labor duration in the HP group of (120). The 4 groups showed a significant difference (p=0,032). The results showed that the test difference between the 2 treatment groups were as follows, the HP VS HA group had a difference but not significant (p=0,171), the HP VS AK group had a significant difference (p=0,031), there was a significant difference in the HP VS K group (p=0,006). HP was compared to the control group with an RR of 2,5 (CI 1,739 -28,174), meaning that the RR number was statistically significant and had 2,5 times shorter labor duration than the control group. ARR of 45% means that the difference in the ability of HP treatment in shortening the length of labor is 45% compared to the control group. Conclusion HP is more effective in shortening the duration of the first stage of labor in the active phase of primigravida.

Published: September 2022

Introduction: High-efficiency switching mode envelope elimination and restoration (EER) RF power amplifiers (PA) are the most promising of a number of "synthetic" power amplification methods for a wide variety of applications. However, when they operate on a mismatched narrow-band load, for example, an electrically short antenna, additional out-of-band emission occurs, which limits the EER PA scope. The purpose of the work is to develop a simulation model for studying the EER switching mode RF PA operation for a narrow-band load. The choice of transient analysis method and use of the freely distributed simulation environment Micro-Cup 12 are substantiated. A number of original solutions are proposed to reduce the computation time. The description of developed model is given, which makes it possible to study the features of the EER PA operation on a narrow-band antenna on a real signal with amplitude& phase modulation fragment. As an example, a DRM digital radio OFDM signal with 10 kHz bandwidth is used. Studies conducted using this model can be proportionally scaled for any frequency band and will allow further development of technical requirements for the EER PA blocks characteristics. Some calculations results showing the developed model adequacy are presented. Practical significance: the use of this model for the subsequent search for solutions to ensure the possibility of EER PA operation for a narrower band load will expand the scope of these high-efficiency power amplifiers.
The role of infographic elements in the perception of the recipient -an analytical study on the infographic page in Al-Naba newspaper
Authors: ALmishhdani Saad Salman Abdallah , Abadi Emad Obeis
Published: September 2022

Infographic elements (numbers, colors, shapes, and symbols) play a major role in infographic design, because of their impact on the recipient’s perception of the messages to be delivered, so the communicator cannot achieve his goals without them, as numbers and statistics are important elements in the infographic. A large amount of information and data inside the body of the figure is a process that cannot be achieved without numbers, and that its presentation in an interesting and attractive way is not done without the use of colors, and the process of highlighting the important part of the message to be communicated requires a variation in the distribution of colors within the design body. And if we want the message to be stuck in the mind of the recipient, the symbols are enough to achieve this because of their ability to consolidate the message in the mind of the recipient, which helps to remember it when exposed to it a second time. code instead. In order to display them in a smooth and understandable way for the recipient, we must use shapes, whether they are geometric shapes such as square, rectangle, circle and other regular or irregular shapes.

Published: September 2022

Relevance: Timely detection and assessment of the prevalence of pancreatic neuroendocrine tumors (p-NETs), visualization of the status of somatostatin receptors, along with morphological characteristics, fundamentally affects the tactics of treatment and long-term prognosis. In recent years, a highly specific diagnostic method 68Ga-DOTATATE PET/CT has become available in Russia.   Purpose: Evaluation of the effectiveness of  68Ga-DOTATATE PET/CT in staging and detection of p-NETs recurrence in comparison with routine visualization methods.   Material and methods:  68Ga-DOTATATE PET/CT was enrolled in 55 patients diagnosed with p-NETs. Information on previous treatment was studied, as well as reports and images of CT and MRI performed no earlier than 2 months before PET/CT. In all patients, we counted foci of pathological accumulation (FPA) of  68Ga-DOTATATE, both the total number and their distribution in various organs and anatomical zones. The number of FPA on PET/CT was compared with the number of metastases on CT and MRI. Verification of FPA was carried out by follow up PET/CTs, as well as histological examination of the surgical material obtained after the resection of tumor foci after PET/CT.   Results: Out of 55 patients, FPA were detected in 48 (87.3 %). Metastases were observed on CT and MRI in 36 patients (65.5 %).  68Ga-DOTATATE PET/CT compared with previous CT and MRI helped to identify an additional 12 people with tumor lesions. The localization of the tumor process on PET/CT completely coincided with CT and MRI in 21 patients. In five patients, the malignant process on PET/CT was detected in the same anatomical areas or lymph nodes as on CT and MRI, but additional foci were detected in these areas. In seven patients, PET/CT revealed distant lung, small pelvis and bone metastases, which were not detected earlier. Secondary isolated liver lesions were detected on CT and MRI in 10 patients. PET/CT revealed additional metastases in lymph nodes and bones in three of them. Secondary lymph node lesions on PET/CT was registered in 24 patients. On CT and MRI in 13 (diameter ≥10 mm). According to CT and MRI, metastases were detected only in the abdomen in 34 patients. PET/CT data matched in 20 (58.8 %) of them. In 14 patients (41.2 %): additional foci were found in the liver, lymph nodes, pelvis and bones. Lung metastases were detected on CT and PET/CT only in one case. Bone lesions on PET/CT were noted in eight patients, on CT and MRI in two. In four patients, primary multiple neuroendocrine tumors of other localizations (small, large intestine, kidney) were detected. Another four patients had multiple p-NETs.

   Conclusion:  68Ga-DOTATATE PET/CT makes a significant contribution to the assessment of the p-NETs prevalence, allows optimizing the tactics of antitumor treatment.

Purpose: To evaluate the effect of previously performed radiation therapy on the successful use of a submental flap in oral reconstruction.   Material and methods: The study included 52 patients who underwent reconstruction of oral cavity defects using a submental flap between February 2015 and January 2021. Radiation therapy was performed in 13 patients in the preoperative period at different time periods and in different doses.   Results: From February 2015 to August 2021, to 52 patients submental flap was used to reconstruct oral cavity defects after surgical treatment of oral mucosal cancer. 13 patients received radiation therapy before surgical treatment compared to 39 who did not. In eleven cases, partial flap necrosis occurred, of which 3 underwent radiation therapy to two in a radical dose before surgical treatment. In two cases, there was a discrepancy of sutures in the oral cavity, one in each group, which did not require surgical intervention and were closed with conservative treatment. Two patients who underwent radiation therapy developed a fistula communicating with the oral cavity and neck healed spontaneously with conservative management. Marginal mandibular nerve palsy developed in three patients, one in the group with radiation therapy, the rest without a history of radiation therapy.   Conclusions: Total flap necrosis was not observed in any group. Thus, preoperative radiation therapy is not a contraindication to the use of a submental flap to reconstruct oral cavity defects with relatively acceptable complications. The submental flap is easy to harvest, reliable, universal flap to reconstruct oral cavity defects.

Purpose: To evaluate the severity of early radiation reactions and the first results of proton therapy treatment of patients with squamous cell carcinoma of the head and neck.   Material and methods: From January 2019 to March 2022, more than 1 400 patients received proton therapy on the proton-cyclotron complex ProteusPlus235. The search for patients was carried out in the database of patients who received proton radiation therapy for oncological diseases in the FMBA system of Russia. The study included 62 patients with confirmed squamous cell carcinoma and the unifying model was: proton therapy in the mode of five-day fractionation of SFD 2 Gr, TFD 50 Gy for locoregional lymphatic collector zones and TFD 60–70 Gy for the area of the primary tumor focus and high-risk zones. The age group is from 18 to 78 years. According to the classification of ICD10 — 35 patients were diagnosed with C00–C14 “Malignant neoplasms of the lip, oral cavity and pharynx” (56,4 %), 27 patients with C30–C32 “Malignant neoplasms of the upper respiratory organs” (43,5 %).   Results: The assessment of long-term treatment results and the severity of radiation complications requires a systematic and uniform approach and is the subject of further research, along with the development of optimal patient models for treatment by proton pencil-beam scanning therapy.   Conclusions: Proton beam and proton chemoradiotherapy have demonstrated decreasing trends or comparable frequency and severity of radiation reactions compared to photon therapy. In this regard, the decision to choose a treatment method should be based on an assessment of clinical efficacy, relapse-free and event-free survival, which is the subject of further scientific research.

A spurious correlation between difference scores in evidence-accumulation model parameters
Authors: Grange James A. , Schuch Stefanie
Published: September 2022

Evidence-accumulation models are a useful tool for investigating the cognitive processes that give rise to behavioural data patterns in reaction times (RTs) and error rates. In their simplest form, evidence-accumulation models include three parameters: The average rate of evidence accumulation over time (drift rate) and the amount of evidence that needs to be accumulated before a response becomes selected (boundary) both characterise the response-selection process; a third parameter summarises all processes before and after the response-selection process (non-decision time). Researchers often compute experimental effects as simple difference scores between two within-subject conditions and such difference scores can also be computed on model parameters. In the present paper, we report spurious correlations between such model parameter difference scores, both in empirical data and in computer simulations. The most pronounced spurious effect is a negative correlation between boundary difference and non-decision difference, which amounts to r = – .70 or larger. In the simulations, we only observed this spurious negative correlation when either (a) there was no true difference in model parameters between simulated experimental conditions, or (b) only drift rate was manipulated between simulated experimental conditions; when a true difference existed in boundary separation, non-decision time, or all three main parameters, the correlation disappeared. We suggest that care should be taken when using evidence-accumulation model difference scores for correlational approaches because the parameter difference scores can correlate in the absence of any true inter-individual differences at the population level.
Parent Teacher Home Visits: An Approach to Addressing Biased Mindsets and Practices to Support Student Success

Published: September 2022

Research has shown educators’ implicit biases to be a key factor in creating and perpetuating disparities in students’ experiences of schooling, learning, and longer-term outcomes, including job opportunities, wealth, and health. Current school reform and transformation efforts are aimed at addressing institutionalized racism in school policies, practices, and cultural systems by implementing implicit bias training for teachers and staff. In this paper, we explain how a school home visits program, Parent Teacher Home Visits (PTHV), is a promising intervention for counteracting implicit biases and improving outcomes for families and students. The PTHV “relational” home visit model focuses on promoting mutually supportive and accountable relationships between educators and families. We present data from a study examining the experiences of 107 educators and 68 family members who participated in PTHV, showing how educators shifted their deficit assumptions about families and students. Although the PTHV model was not created to address implicit biases, we found that the key components of these home visits align with strategies that psychological research has demonstrated effectively counteracting implicit biases and reducing discriminatory behaviors.

Published: September 2022

It is emphasized in the article that thanks to the discovery of D. I. Mendeleev and the Periodic Table of chemical elements existing for more than 150 years, as well as the international table IUPAC, chemistry has been actively developing and keeps developing. A new model for arranging chemical elements in the form of a three-dimensional matrix has been proposed. This makes it possible to predict new elements with the designation of nuclear masses and the electronic structure of shells. There have been developed new patterns according to the cyclicity (block structure) of horizontal rows and the structure of vertical groups and their physical conception have been specified.

Boroorganic and phosphorogenic polyols in the processes of separation of liquid mixtures (extractive rectification, first vaporation)
Authors:   Kazan National Research Technological University, Klinov Alexander V.
Published: September 2022

Aminoesters of boric and orthophosphoric acids (AEBA and AEPA) were studied as potential extractants for the separation of azeotropic water-alcohol mixtures by extractive rectification. The conditions of vapor-liquid equilibrium in aqueous solutions of ethanol - water, isopropanol - water in the presence of AEBA and AEPA have been investigated. Within the framework of the UNIFAC model, a partition of AEBA molecules into group components is proposed and previously unknown geometric and energy parameters are determined. On the basis of AEBA and AEPA, polyurethane ionomers have been obtained and studied as a material for a selective layer of pervaporation membranes for separating ethanol-water and isopropanol-water mixtures.
XVI ve XVII. Yüzyılda Osmanlı İmparatorluğu ve Asya Ticareti
Authors: Mantran Robert
Published: September 2022

En parlak döneminde yani XVI-XVII. yüzyıllarda Osmanlı İmparatorluğu tarihi, her şeyden önce Akdeniz'e ve Orta Avrupa'ya doğru kaymış bulunmaktadır: Batılılarla savaşlar, diplomatik ilişkiler, ticarî bağlar seyahatnamelerde, yıllıklarda ve hattâ dönemin tarih kitaplarında oldukça büyük bir yer tutmaktadır. Bu, tarihi yalnız Avrupa açısından kavrayan batıcılar için kutsal bir gelenektir. XVI. yüzyılda I. Selim ve Muhteşem Süleyman'ın saltanatları döneminde Osmanlı İmparatorluğu'nun Yakın Doğu'daki Arap ülkelerini topraklarına katarak genişlediğini unutmamak gerekir: Bunlar, Suriye, Filistin, Mısır, Irak ve Arabistan idi.
1274/1858 Tarihli Osmanlı Ceza Kanunnamesinin Hukuki Kaynakları, Tatbik Şekli ve Men'-i İrtikâb Kanunnamesi
Authors: Akgündüz Ahmet
Published: September 2022

Osmanlı hukukçularına göre ceza hukuku, "insan toplumunun Allah tarafından irade edilen şekilde medeni olarak yaşayıp terakki edebilmesi için vaz' edilen kanun ve nizamların hükümlerini korumak amacıyla konulan kaidelerden" ibarettir. Kanun ve nizamların hükümlerini koruma görevi ceza hukukuna has değilse de, ceza hukuku sırf bu gaye için var olduğundan, bu fonksiyonu ile tarif edilmiştir. Yoksa protesto ve haciz gibi birtakım tedbirler de bu fonksiyonu icra için kabul edilen tedbirlerdir. Yapılan bu tarif temel anlam itibariyle günümüzdekinden farksızdır. Maksat aynı ama ifade ve üsluplar farklıdır. Bilindiği gibi Osmanlı Devleti bir kamu hukuku dalı olan ceza hukuku alanında da, İslam hukukunun hükümlerini benimsemiştir. Onun müsaade ettiği ölçüde bazı ceza kurallarını kabul etmiş ve kanunname tarzında ortaya koymuştur. Bu sebeple Osmanlı hukukunda da ceza hukukuna İslam hukukunda olduğu gibi "Ukubat" denmekte ve Mecelle'de de "Ukubat", yaptığımız tarif doğrultusunda izah edilmektedir.
Urartu At Gemleri

Published: September 2022

Çeşitli kolleksiyonlarda ve müzelerdeki Urartu eserleri arasında değişik formlarda gemlere rastlanır. Bunlardan kitabeli olanlarını açık bir şekilde Urartu gemi olarak kabul etmek zorundayız. Fakat kitabesiz olanların kesinlikle Urartulara ait olduğunu söylemek oldukça zordur. Bu çalışmamızdaki Urartu gemleri, yayınlanmış olan Adana, Van Bölge Müzeleri ve Gaziantep müzesindeki bir kısım gemler ile Elazığ müzesindeki gemlere göre tasnif edilmiştir. Bu malzemeye dayanarak Urartu gemlerinin özelliklerini tesbit etmeye çalıştık.

XVI. Yüzyılda Osmanlı İmparatorluğunda Su-Yolculuk
Authors: Martal Abdullah
Published: September 2022

Osmanlı İmparatorluğunu siyasi açıdan ele alan araştırmalar sayıca belirli bir yere ulaşmasına rağmen, sosyal yönüyle, özellikle alt yapı kuruluşlarıyla ilgili çalışmaların çok az olduğu gözlenmektedir. Osmanlıların sosyal yapısını ilgilendiren konulardan biri de su işleridir. Su, her zaman insanların günlük yaşayışlarında vazgeçilmez unsurlardan biri olmuştur. Bu sebeple, Osmanlılarda su işlerinin nasıl yürütüldüğünü, bu konuda neler yapıldığını ve günümüze neler kaldığını öğrenmek yerinde olur. Ayrıca, XX. yüzyılın ikinci yarısında tarih araştırmalarına getirilen yeni boyutlara bir tamamlama niteliği taşıyabilir.
Gaziantep Câmilerinde Minber Problemi ve Müteharrik Minberler
Authors: Çam Nusret
Published: September 2022

Anadolu'da sanat tarihi araştırmacılarının en az dikkatini çeken bölgelerden biri de Gaziantep'tir. Bunda, bu çevredeki yapıların abidevi ve gösterişli olmayışının büyük rolü vardır. Gerçekten de Gaziantep'teki sanat değerini hâiz en önemli eserler dahi, daha önceki devirlerde birer sanat ve kültür merkezi olan Konya, Kayseri, Erzurum ve İstanbul gibi şehirlerdeki yapılarla mukâyese edilemeyecek kadar mütevazı yapılardır. Bununla birlikte, bunlarda sadece bu çevreye has diyebileceğimiz, fakat henüz etraflı bir şekilde tetkik edilmemiş bazı özellikler ve unsurlar bulunmaktadır. Konumuzu teşkil eden müteharrik minberler de bunlardan biridir. Biz bu yazımızda Gaziantep câmilerinde minber problemi üzerinde durduktan sonra, aslında konunun bir parçası olan "köşk tipi minberler"i bir başka yazımızın konusu yapmak düşüncesiyle yalnızca "müteharrik minberler"i incelemeye çalışacağız.
Memluk Sultanlığında Devlet Yapısı
Authors: Holt P. M.
Published: September 2022

Memlûk sultanı keyfi karar veren bir otokrattı; ama teknik açıdan ne mutlaktı, ne de tamamen bağımsızdı. Bir müslüman olarak herhangibir tebası kadar İslamın kutsal yasasına tâbi olduğu halde hâkimleri, uygulamada ona karşı kullanabilecekleri müeyyidelerden yoksundular. Sünni hukukçuların tefsirine göre İslam doktrini, İslam toplumunun hükümdarı olarak Allah'tan sonra ancak bir kişiyi tanıyordu, o da halife idi. Bundan dolayı Abbasi hilâfetinin 656/1258 yılında Hulagu tarafından fiziki olarak yok edilmesi, örneği görülmemiş bir durum yarattı. Bu vaziyet 659/1261 yılında Memlûk sultanı az-Zâhir Baybars, iltica eden bir Abbasi emirini Mısır'da kabul edip "al-Mustansır" lakabıyla hilafet makamına oturttuğu zaman şeklen düzelmiş oldu.
Türkiye Seyahati

Published: September 2022

Ratnakosindra döneminin 110. (m. 1891) yılında kral hazretleri kendi mektup, nişan ve madalyalarını Avrupa'nın bazı başkentlerindeki saraylara götürmem için beni özel elçisi olarak görevlendirmişti. Bu görev Türkiye'yi kapsamıyordu. Ancak, Avrupa'daki birtakım küçük ve büyük ülkelere olan mesafeleri haritayı incelemek suretiyle hesapladığım zaman Yunanistan'a Türkiye üzerinden gitmenin diğer yollardan daha kısa ve uygun olduğunu gördüm. Ayrıca Türkiye, Taylandlıların hiç görmediği büyük bir Avrupa ülkesi olarak kabul edilmekle idi. Dolayısıyla seyahat programını, Rus imparatorunu ziyaret ettikten sonra bir posta vapuru ile Karadenize geçip Türkiye'nin başkenti İstanbul'a giderek üç yada dört gün orada kalıp vapurla Yunanistan'a geçecek şekilde yaptım.

Published: September 2022

Kuzey Ege sahilinde Meriç (antik Hebros) nehrinin ağzında kurulmuş bulunan Enez (antik Ainos) mahfuz bir liman olarak Eskiçağ'da büyük bir rol oynadığı gibi, kıyı boyunca batı-doğu yönünde, Avrupa-Asya sahil yolu üzerinde, büyük bir liman şehri olması dolayısı ile de askeri bakımdan da önem taşımıştır. Enez, Eskiçağ'da Taşos (antik Thasos) Boğazı'ndan Çanakkale Boğazı'na kadar olan Kuzey Ege kıyılarında biricik mahfuz bir liman olduğu gibi, Ergene Havzası ile zengin bir hinterlanda sahip bulunduğundan, çok erken çağlardan itibaren iskân edilmiştir.
Osmanlı İmparatorluğu'nda Açılan Amerikan Okulları Üzerine Bir İnceleme
Authors: Polat İlknur
Published: September 2022

Osmanlı İmparatorluğu toprakları üzerinde, Osmanlı eğitim-öğretim kurumları yanında faaliyet gösteren Yabancı Devlet Okulları köken itibarıyla iki boyutlu bir konudur. Önceleri Osmanlı tebaası gayr-ı müslim cemaatler tarafından açılan Millet Okulları'nı daha sonra Yabancı Devletler tarafından açılan Yabancı Okullar izlemiştir. Bu oldukça uzun bir zaman ve olaylar dizisi sonucu belli aşamalardan geçerek gerçekleşmiş bir olgudur. Bu süreci ve tarihsel gelişmeyi görebilmek için de 1453 lere kadar dönmemiz gerekmektedir.

Hititlerde Tuz ve Kullanımı
Authors: Erkut Sedat
Published: September 2022

Bu çalışmaya ileride tuz ile ilgili yapılacak kapsamlı bir araştırmaya baz oluşturmak amacıyla başladık. Elde edilen ilk bulguları yararlı olacağı düşüncesiyle bir an önce yayınlamayı yeğledik. İnsan vücudunun yapı taşlarından olan, halk arasında "yemek tuzu" adıyla anılan Sodyum klorür'e (NaCl) erişkinlerde günde 10-20 gr. gereksinim duyulmaktadır. Bitkisel gıdalarla beslenen insanlarda aldığı besin gereği potasyum vücutta yoğunlaşmaktadır. Potasyum idrarla vücuttan çıkarken sodyumu da beraberinde götürmektedir. Böylece doğal olarak vücuttaki gerekli tuz miktarı azalmakta ve metabolizmanın tuz gereksinimi ortaya çıkmaktadır. Ayrıca terleme ve bazı diğer yollardan vücuttaki tuz eksilmektedir. İlkçağda insanların tarımsal üretime geçmeleri, bitkisel gıdalara yönelmeleri daha az et yemelerine neden olmuştur. Böylece tuzun ek olarak alınması gereksinimi doğmuştur. Bu durum insanları doğal tuz kaynaklarından yararlanmaya yöneltmiştir.
