Konflik Perkawinan Dan Model Penyelesaian Konflik Pada Pasangan Suami Istri

Penelitian ini bertujuan untuk menganalisis perbedaan intensitas konflik perkawinan pada pasangan suami istri yang tinggal bersama dan yang tinggal terpisah dan cara penyelesaian konfliknya. Penelitian ini menggunakan metode kuantitatif dan dilengkapi dengan data kualitatif. Jumlah keseluruhan sampel 74 istri, 47 orang yang tinggal bersama suami dan 37 orang yang tinggal terpisah dengan suami. Teknik sampling yang digunakan adalah purposif accidental sampling. Data dianalisis menggunakan uji-t dan analisa diskriptif kualitatif. Hasil penelitian menunjukkan terdapat perbedaan intensitas konflik perkawinan pada istri yang tinggal bersama dan yang tinggal terpisah dengan suami. Model penyelesaian konflik yang banyak digunakan oleh para istri baik yang tinggal bersama suami maupun yang tinggal terpisah lebih banyak yang mengarah konstruktif dalam penyelesaian konflik perkawinan. Ditemukan persepsi berkebalikan. Menurut istri yang tinggal bersama suami, intensitas konflik perkawinan akan lebih tinggi jika istri tinggal bersama suami. Sebaliknya, menurut istri yang tinggal tidak bersama dengan suaminya, intensitas konflik akan lebih tinggi jika istri tidak tinggal bersama suaminya

Clinicopathological and morphological spectrum of gastrointestinal stromal tumours on multi-detector computed tomography

Purpose: To describe the clinicopathological and morphological features of gastrointestinal stromal tumours (GISTs) on multi-detector computed tomography (MDCT). Material and methods: MDCT (plain and post contrast) images of 25 confirmed cases of GISTs were retrospectively evaluated from our hospital database. The images were analysed for the location, size, growth pattern, attenuation pattern, relation to adjacent structures, presence or absence of ulceration, calcification, metastases, lymphadenopathy, and for any complications such as haemorrhage, intestinal obstruction, etc. Institutional Ethics Committee clearance was obtained prior to the commencement of the study. Statistics used included percentage frequency. Results: Our study group comprised 14 males and 11 females. The mean age of our study population was 60 years (age range: 40 to 82 years). The mean tumour size was 11.7 cm. The stomach and small bowel accounted for 76% of the primary tumour site. The commonest imaging appearance of GIST observed in our study was that of an exophytic mass (76%) with a heterogenous pattern of enhancement (96%) with intratumoural necrosis (76%). MDCT demonstrated complications in three patients (12%). Six patients presented with metastatic foci (five to the liver and one to the lung), while lymphadenopathy was observed in five patients (20%). Associated complications included intestinal obstruction (8%) and retrogastric haematoma (4%). Incidental findings included uterine fibroid (n = 1), ovarian dermoid (n = 1), and chronic pancreatitis (n = 1). Conclusions: GISTs are predominantly large tumours with a well circumscribed and exophytic pattern on MDCT, with or without cystic/necrotic areas, and they mostly show a heterogenous pattern of enhancement on post-contrast administration

Superfluid helium testing of a stainless steel to titanium piping transition joint

Stainless steel-to-titanium bimetallic transitions have been fabricated with an explosively bonded joint. This novel joining technique was conducted by the Russian Federal Nuclear Center, working under contract for the Joint Institute for Nuclear Research. These bimetallic transitions are being considered for use in future superconducting radio-frequency cavity cryomodule assemblies. This application requires cryogenic testing to demonstrate that this transition joint remains leak-tight when sealing superfluid helium. To simulate a titanium cavity vessel connection to a stainless steel service pipe, bimetallic transition joints were paired together to fabricate piping assemblies. These piping assemblies were then tested in superfluid helium conditions at Fermi National Accelerator Laboratory test facilities. The transition joint test program will be described. Fabrication experience and test results will be presented

The search for gravitational waves

In this paper we briefly review the status and the perspectives of the experimental search of gravitational waves, focusing on the ground based interferometers. The current status of the running detectors and the plans to upgrade them are discussed

All-sky search for short gravitational-wave bursts in the second Advanced LIGO and Advanced Virgo run

We present the results of a search for short-duration gravitational-wave transients in the data from the second observing run of Advanced LIGO and Advanced Virgo. We search for gravitational-wave transients with a duration of milliseconds to approximately one second in the 32-4096 Hz frequency band with minimal assumptions about the signal properties, thus targeting a wide variety of sources. We also perform a matched-filter search for gravitational-wave transients from cosmic string cusps for which the waveform is well modeled. The unmodeled search detected gravitational waves from several binary black hole mergers which have been identified by previous analyses. No other significant events have been found by either the unmodeled search or the cosmic string search. We thus present the search sensitivities for a variety of signal waveforms and report upper limits on the source rate density as a function of the characteristic frequency of the signal. These upper limits are a factor of 3 lower than the first observing run, with a 50% detection probability for gravitational-wave emissions with energies of ∼10-9 Mc2 at 153 Hz. For the search dedicated to cosmic string cusps we consider several loop distribution models, and present updated constraints from the same search done in the first observing run
