Bell Equipment will introduce its new 60-ton truck concept, the B60, at Bauma Africa in September. The B60 takes Bell's articulated dump truck design into a larger class, opening opportunities in domains previously only served by rigid haulers. It combines the ADT concept with a single rear axle, providing a 4x4 vehicle with full articulation and oscillation for improved traction. Testing has shown the B60 provides a smooth ride and lower operating costs than conventional rigid trucks. Bell plans to test the B60 further after its unveiling and build more units for customer testing in 2014.

The document summarizes Maple Leaf Cement's (MLCF) 1HFY15 results and future outlook. MLCF reported a 9% increase in revenue due to higher local sales demand.

MLCF also announced an interim cash dividend of Re. 1/share, enabled by its continuous repayment of long-term debts over the past two years. The company represents a good investment opportunity at its low PE of 6.6-7x for FY15.

This document provides an overview of the four ports (P0, P1, P2, P3) on the 8051 microcontroller. It describes each port's structure, address, and how they can be configured as input or output ports. P0 is an 8-bit multi-function port that can generate the lower address and data bus. P1 is a single-bit simple I/O port. P2 is an 8-bit multi-function port that can generate the upper address bus. P3 is an 8-bit multi-function port with some pins having alternate functions like interrupts or serial communication. The document explains how to configure each port as an input by writing 1's to the port latch,
