Best of both worlds or refusal to comply? The rich kids of Tehran on Instagram

ABSTRACT

This article offers a textual analysis and semiotic reading of the Rich Kids of Tehran's (RKOT’s) Instagram page. Contributing to scholarship on Iranian youth media practices, this article interrogates how the RKOT navigate urban and rural space to engage in everyday processes of resistance against global and local systemic oppression. Grounding their visual representations on Instagram in historical and cultural context, the author questions how and when quotidian actions are transformed into political transgressions when posted on social media. This article emphasizes the RKOT's agency in shaping their brand by analyzing representations of gender performance, intertextuality, and national identity on Instagram.     

单片机的模块化设计

设计一种带有多种输入输出接口的单片机系统,使其成为模块化,能对各种电器进行控制管理,实现智能化,具有简单、经济、实用、方便等特点。     

一种有限非交换环的构造方法

先分别对高斯整环Z(i)=｛a bi｜a,b∈Z｝的元素a bi的实、虚部a,b按模n同余分类得到Zn(i)=｛[a] [b]i｜a,b∈Z｝,再利用两个的直积构造了一类有限非交换环。

基于Web服务的MyLibrary@HUST系统*

在分析了当前一些成熟的MyLibrary系统的基础之上,以XML/Webservice/WSDL技术为基本实现框架，提出了一种全新的三层结构的MyLibrary系统,并详细介绍了三个功能层的核心任务和相应的软件实现。此系统在开放性、个性化、安全性等方面都较现有的系统有一定的改进。     

振动沉管桩贯入阻力对设计、施工的影响

振动沉管桩因其在施工中明显的优势而被广泛采用，但实际操作中常出现沉桩达不到设计标高现象，而不得不改变施工工艺、更换设备或变更设计，从而延误工期，增加投资等情况。本文通过对振动沉桩的贯入机理、贯入阻力的估算、取值方法、阻力判定及实例分析，让设计、施工人员在设计、施工沉管桩时能合理地确定施工方法、进度、质量。     

Efficacy of massage on muscle soreness,perceived recovery,physiological restoration and physical performance in male bodybuilders

It is believed that sport massage after intensive exercise might improve power and perceptual recovery in athletes. However, few studies have been done in this area. This study aimed to examine the effect of massage on the performance of bodybuilders. Thirty experienced male bodybuilders were randomly assigned to either a massage group (n = 15) or a control group (n = 15). Both groups performed five repetition sets at 75–77% of 1RM of knee extensor and flexor muscle groups. The massage group then received a 30-min massage after the exercise protocol while the control group maintained their normal passive recovery. Criteria under investigation included: plasma creatine kinase (CK) level, agility test, vertical jump test, isometric torque test, and perception of soreness. All variables were measured over 6 time periods: baseline, immediately after the DOMS inducing protocol, right after the massage, and 24, 48, and 72 h after the massage. Both groups showed significant (P < .001) decreases in jumping, agility performance, and isometric torque, but significant (P < .001) increases in CK and muscle soreness levels. The massage group in general demonstrated a better recovery rate. As such, a post-exercise massage session can improve the exercise performance and recovery rate in male bodybuilders after intensive exercise.
