The main purpose of the present study is a comparison of the effects of two kinds of resistance exercise on the maximum strength of the quadriceps and pectoralis major muscles. The subjects of the study were 45 non-athlete, university male students (mean age: 18.5±0.64, 70±10 Kg, 173±5.7 cm) voluntreered to be tested.They were divided into three equal groups of 15 randomly. The name given to them were: a) Mac- CLOYs, b) Delorme-Watkinz and c) Control group.Training groups (a) and (b) performed their specific training program for four days a week for 6 weeks. Analysis of variance (ANOVA) test indicated that maximum strength remarkably increased in training groups (a) and (b). Mac-CLOY group was even more than Delorme-Watkinz group (P<0.05). But there were significant differences between training methods and increment of maximum strength in pectoralis major muscle. The testing of other hypotheses indicated that there are no significant differences among the different groups of the study.

Aims The use of intrauterine devices (IUDs) has been one of the most effective, the safest and cost-effective methods for preventing pregnancy, for a long time. However, some complications have been reported for IUDs. The complications may be reduced by using a specific TECHNIQUE for placement of IUD. The objective of this study was to introduce the rotating withdrawal TECHNIQUE for the first time, which was investigated to reduce the complications of IUD insertion. Materials & Methods This historical cohort study was conducted on 1199 females who referred to Sarem Medical Center for IUD insertion from 1984 to 1995. After primary examinations, IUD was inserted by rotating withdrawal TECHNIQUE. The subjects were followed up for 2 years. Findings Displacement was observed just in 20 cases (1. 67%). All of them were seen in the first month after placement. For these cases, IUD insertion was done again. After the second replacement, displacement was observed in 4 cases (0. 035%) after one month. Therefore, it was recommended to them to use another preventive method. There was no pregnancy or displacement in the other cases during 2 years. Conclusion The rotating withdrawal TECHNIQUE can minimize the pregnancy rate when IUD is used. In addition to the type and quality of IUD, insertion method of IUD can increase its effectiveness.

In this paper, a new method for extending and relaxing the noise-coupling (NC) TECHNIQUE is proposed to enhance the noise-shaping order without adding the number of integrators. The noise-shaping order of the introduced ∑∆ modulator whit applying a second-order noise-coupling TECHNIQUE is enhanced and its performance with optimizing the noise transfer function (NTF) zeros is improved. Also, by removing the analog adder at feedforward path and transferring it to a new feedback branch before the last integrator and adding second-order NC path can be decreased the input voltage swing to the quantizer. Thus, by improving the modulator resolution, power consumption can be reduced. Mathematical analyses and behavioural simulation results confirm the effectiveness of the new NC method. To examine its performance, a 2nd-order single loop ΣΔ modulator was designed. The new noise-coupling method is used to achieve the three-order noise shaping to increase the resolution with low complexity and low-power. The results show an outstanding improvement in signal-to-noise and distortion ratio (SNDR) compared to the conventional structure.

McDonaldization is an official process in which the principles of fast food restaurants are exercised. The McDonaldization of various social institutions has succeeded because it provides advantages over other, usually older, methods of doing business. It has made McDonaldized social institutions bureaucratic and rational in a Weberian sense and, thus, more efficient, calculable, predictable, and controlling over people (often by nonhuman technologies). The principal problem with McDonaldized institutions, and another characteristic of the process, is irrationality or, as Ritzer calls it, the “irrationality of rationality.” A primary purpose of this essay is to expose some of the irrationalities of “McJustice” and to suggest some possible responses to them.

Marriage is a legal bond between a man and woman before religion and law. Every couple often experiences marital conflict due to differing mindsets, cultures, and values, necessitating adjustments. The families and spouses of military personnel become integral parts that must adhere to the same rules. Marriages involving military personnel encounter more complex conflicts compared to civilian communities due to differences in culture, language, personality, lifestyle, and education. The assignment of duties or missions can be a source of conflict, necessitating adjustments from spouses as they serve as the main support system for these personnel to carry out their missions effectively. In addition, unresolved conflicts in military marriages pose significant risks and must be addressed promptly. This literature review aims to explore couple therapies for military couples by examining relevant articles and publications from 2015 to 2020. A total of 21 qualified published literature pieces and four ebooks were reviewed. The results revealed several types of military couple therapy counseling, including emotional-focused therapy (EFT), solution-focused therapy (SFT), and cognitive behavior couple therapy (CBCT), which can effectively address differences and individual desires within the relationship. These therapies are practical and time-efficient, making them less reliant on a specific therapist, especially considering the frequent changes in duties experienced by military personnel. The therapy selection is based on individual needs, requiring cooperation from both partners to improve their relationship.

Gelled propellants are improved propellants that can be considered as the final extension of liquid propellants. High specific impulse, good density, a safety better than that of both solid and liquid propellants and thrust management ability are some of the advantages of these propellants compared with common solid and liquid propellants. In early decades, an extensive research has been carried out on making, quality control, combustion and application of these propellants. Gelled propellants can be used in air breathing systems, pilot seat ejection systems, smart propulsion missiles, advanced launch-vehicle boosters, etc. In this research a review of the papers on making gelled propellants was carried out, on the basis of which, the basic properties and characteristics of gelled propellants are described. Then methods for making important gel fuels and oxidizers such as, hydrazine, mono methyl hydrazine (MMH), unsymmetrical dimethyl hydrazine (UDMH), kerosene, inhibited red fuming nitric acid (IRFNA) and nitrogen tetroxide are presented. Next gelled simulants, their applications and preparation methods as a background for making main gelled propellants are described. In order to study the possibility of making MC-UDMH gelled propellants, MC-H2O gelled simulant was made in the laboratory and the rheological behavior of this simulant was investigated. Results showed that the prepared MC-H2O gel has good rheological behavior and can be used as a simulant for UDMH gelled propellants.

High gain Balun-low-noise-amplifier (LNA) is proposed for tuner of digital televisions (DTVs). The proposed Balun-LNA is based on CS-CG (common-source-common-gate) structure. To improve the isolasion and frequency response, Balun-LNA has cascode transistors before load resistors. Balun-LNA uses current-bleeding circuit to increasie transconductance of CS transistor, so that current-bleeding transistor has transconductance of N-1 times larger than transconductance of cascode transistor. Thereby, transconductance and current of CS transistor are increased N times, as N-1 times of current pass to current-bleeding transistor. Therefore current of CG and CS stages stay identical. Also, Balun-LNA employs a positive feedback to satisfy input impedance matching and CG transistor has higher transconductance. By increasing transconductance of CS and CG transistors, the proposed Balun-LNA achieves to high voltage gain. Accordingly, CG and CS tansistors have symmetrical currents and loads at the differential output of the proposed Balun-LNA. Symmetrical loads cause the balanced differential outputs. This proposed Balun-LNA is designed in 90-nm CMOS technology and covers the frequency range of 40 MHz to 1GHz. This Balun-LNA achieves the voltage gain of 22.6 dB, S11 of less than -10 dB and the Minimum NF of 5 dB. This Balun-LNA operates at the nominal supply voltage of 2.2v.
