In contrast to the classical antibacterial sulfa drugs that are unsubstituted or monosubstituted, our newly synthesized analogs were designed to obtain sulfonamide moiety containing disubstituted hetero nitrogen atom. These compounds were formed successfully by chlorosulfonation of acetanilide and the product was treated with different cyclic amines and finally amide hydrolysis was necessary to get agents that were analyzed for IR, UV, CHN, melting points and solubility. At last, we studied their antibacterial activity on certain types of bacteria and we noticed the inactivity due to possible steric factor. Principly, this means these products have no inhibiting action against the used microbes.

Abstract

Back ground: Renal cell carcinoma is an uncommon condition that develops during pregnancy. Due to a lack of conventional norms and a dearth of literature, its management is a serious issue.

Case presentation: We will discuss a case study of a twenty-year-old female girl who is pregnant G1 P1 A0, has had five missing periods (20 weeks gestation), and has frank hematuria due to a massive, incidentally detected renal cell carcinoma. We also go through the current guidelines for treating kidney malignancies during pregnancy, as well as the imaging studies that are now available.

Conclusion: Although the best time for surgery is debatable, a mult

The paper presents the design and modeling of a twenty-channel, bidirectional WDM-PON architecture with IM/DD for the 5G fronthaul in C-RAN systems. The proposed architecture is fully compliant with the ITU-T G-series Supplement 66 requirements on next-generation fronthaul interfaces. Each channel has a data-carrying bit rate of 25 Gbps, thus yielding a total capacity of 500 Gbps for the entire system. The entire design has been simulated in OptiSystem V.22. The analysis of the BER for different lengths of fiber and continuous wave laser power conditions provides the performance evaluation. Through simulation results, it can be confirmed that the system conforms to the F1 and Fx functional split specifications that are u

The urban fabric of contemporary cities is experiencing a decline in spatial memory and collective identity as a result of rapid transformations in urban form and behavior. This research is based on the hypothesis that the continuity and spatial integration of the morphological structure enhance spatial perception and belonging, and that this interconnectedness forms the basis for reviving urban identity. The study adopts an analytical-comparative approach that combines digital spatial analysis using DepthmapX and social analysis through a field survey of residents. This approach compares three historic cities that represent different patterns of spatial memory revival: Fez, which preserved the coherence of its organic f

Bridges are one of Baghdad’s most important infrastructure elements, today they are not only for crossing the river and connecting Karkh and Rusafa, but serve as strategic tools to ease traffic congestion resulting from population density and rapid urbanization. With a population exceeding eight million and a growing number of vehicles, maintaining and sustaining bridges through continuous monitoring and inspection has become essential. Yet the current inspection process faces many challenges. This research aims to identify factors hindering optimal bridge inspection and to provide solutions for improved inspection performance. These challenges stem from managerial, technological, economic and environmental issues, red

One of the biggest problems facing the construction sector throughout the globe is financial risks. This is especially true for building projects in Iraq.  These hazards often result in project delays and budgetary constraints.  The goal of this research is to find the reasons behind financial hazards.  A questionnaire was used to discover and extract sub-factors.  A probability and effect matrix was also used to provide a quantitative study of these parameters. We also utilized the relative relevance index to rank the hazards.  The study's findings revealed that eight factors significantly influenced the project, categorized as high risk: inaccurate cost estimates, delayed client payment processes, clients' financi

Efficient design of weaving sections is critical for maintaining smooth traffic flow on urban arterial roads. This study investigates optimal weaving lengths (WL) for improving traffic flow efficiency using two weaving sections located on Malik Mahmud Ring Road in Sulaymaniyah City, Kurdistan Region, Iraq, as a case study. Traffic and geometric data were collected through drone footage and processed using data from Sky Viewer to extract detailed vehicle trajectories. A calibrated and validated microsimulation model was developed in PTV VISSIM 2024 to replicate real-world traffic conditions. A full factorial experimental design tested the effects of WL, mainline traffic volume, and weaving volume on section performance. T

ان حقوق الملكية الفكرية على اختلاف انواعها، وطبيعتها تعتبر مكنة في يد مالكها تمكنه من الاستئثار بالمنافع التي تخولها لهم لها من دون منازعة او وساطة من احد، حيث نجد ان القوانين المنظمة لحقوق الملكية الفكرية تهدف الى تعزيز الابتكار من خلال اقرار الحق الاستئثاري لمالك حقوق الملكية الفكرية على ما توصل اليه من نتاج فكري، ومنع الغير من استغلاله من دون الحصول على اذن من مالكه، كل ذلك ينعكس بشكل ايجابي على تقدم الم

بدأ المجتمع الدولي يدرك على إثر اكتشاف الثروات الهائلة في المناطق التي تقع خارج حدود السيادة الإقليمية للدول، بأن الفارق الهائل في التطور العلمي والتكنولوجي بين الدول المتقدمة والدول النامية، قد يمنح للدول المتقدمة فرصة استغلال هذه الثروات، وهذا ما سيؤدي بدوره إلى اتساع الفجوة بين الدول المتقدمة والدول النامية، وترسيخ مبدأ عدم المساواة بسبب عدم امتلاك دول العالم الثالث الامكانيات التي تتيح لها المشاركة

In this paper, the finite element method is used to study the dynamic behavior of the damaged rotating composite blade. Three dimensional, finite element programs were developed using a nine node laminated shell as a discretization element for the blade structure (the same element type is used for damaged and non-damaged structure). In this analysis the initial stress effect (geometric stiffness) and other rotational effects except the carioles acceleration effect are included.  The investigation covers the effect speed of rotation, aspect ratio, skew angle, pre-twist angle, radius to length, layer lamination and fiber orientation of composite blade. After modeling a non-damaged rotating composite blade, the work procedure was to ap

Four samples of the Se55S20Sb15Sn10 alloy were prepared using the melting point method. Samples B, C and D were irradiated with (6.04×1010, 12.08×1010 and 18.12×1010 (n.cm-2s -1 ) of thermal neutron beam from a neutron source (241Am-9Be) respectively, while sample A was left not irradiated. The electrical properties were assessed both before and after the radiation. All irradiated and non-irradiated samples show three conduction mechanisms, at low temperatures, electrical conductivity is achieved by electron hopping between local states near the Fermi level. At intermediate temperatures, conduction occurs by the jumping of electrons between local states at band tails. At high temperatures, electrons transfer between extended stat

Background Bilateral cleft lip deformity is much more difficult to correct than unilateral cleft lip deformity. The complexity of the deformity and the sensitive relationships between the arrangement of the muscles and the characteristics of the external lip necessitate a comprehensive preoperative plan for management. The purpose of this study was to evaluate the repair of bilateral cleft lip using the Byrd modification of the traditional Millard and Manchester methods. A key component of this repair technique is focused on reconstruction of the central tubercle.

Methods Fourteen patients with mean age of 5.7 months presented with bilateral cleft lip deformity and were operated on using a mod

The rapid rise in the use of artificially generated faces has significantly increased the risk of identity theft in biometric authentication systems. Modern facial recognition technologies are now vulnerable to sophisticated attacks using printed images, replayed videos, and highly realistic 3D masks. This creates an urgent need for advanced, reliable, and mobile-compatible fake face detection systems. Research indicates that while deep learning models have demonstrated strong performance in detecting artificially generated faces, deploying these models on consumer mobile devices remains challenging due to limitations in computing power, memory, privacy, and processing speed. This paper highlights several key challenges: (1) optimiz

Abstract. Shock chlorination is a well-known practice in swimming pools and domestic wells. One of the limitations for using this technique in drinking water purification facilities is the difficulty of quickly removing high chlorine concentrations in water distribution systems or production facilities. In order to use this method in the drinking water industry a shock de-chlorination method should be introduced for producing microorganism and biocide free water. De-chlorination using natural stagnant aeration (leaving the water to lose the chlorine naturally) is the safest known method if compared with chemical and charcoaling methods. Unfortunately, stagnant aeration is a slow process. Therefore, developing a process for accelerat

The new modified Runge-Kutta methods (MRK) contain the invalidation of phase lag, phase lag’s derivatives, and amplification error. Numerical tests from their outcomes show the robustness and competence of the new methods compared to the well-known Runge-Kutta methods in the scientific literature.

Federal Russia remains the central player in the space of post-Soviet Union,
particularly in the regions of Middle Asia and the Caucasus , which set standard for
the local transformations of the two regions.
The Russian concern continued about the shift of power in the
world, as long as Russia is concerned with limiting the action of the United States
in the area in which Russia sees as vital area to its national interests. Russia's
nationalists play a main role in reviving Russia's influence in Middle Asia as a vital
area and the natural ally of Russia, but without resorting to the old ways of using
the threat of military force.
The idea of the return of Russia as a superpower in the global arena in

The intervention in the military institute represents a great role in the Nigerian
political life since 1960. There are many reasons behind this domination. The First is that
many African militants participated in liberating their countries from colonization. The
second is that they tried to stay in power as long as they could stay through the rule of one
party.
There fore, they depend on the process of political and economic reform to get rid of
military rule that dominated the Nigerian Political life to be a civilian state
